This application is the continuation application of International Application No. PCT/CN2024/126696, filed on October23, 2024, which is based upon and claims priority to Chinese Patent Application No. 202311389835.6, filed on October24, 2023, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to the technical field of humidification, and in particular, to an evaporative humidifier and a storage method thereof.

BACKGROUND

A conventional evaporative humidifier typically includes three structural modules: a water tank, a wet curtain assembly, and an air supply assembly. Its operating principle can be summarized as follows: Water stored in the water tank moistens a wet curtain, and the air supply assembly drives air to flow through the wet curtain, thereby humidifying the air. As a key performance indicator, humidification capacity refers to the rate at which the humidifier humidifies the air. A higher humidification capacity corresponds to a faster water consumption rate. Accordingly, a high humidification capacity typically requires a large-capacity water tank. Thewater tank acts as a water storage structure, and itssize is positively correlated with its water storage capacity. Generally, a larger water storage capacity results in a larger water tank and thus a larger overall size of the final product, which causes inconvenience in both transportation and storage.

In conclusion, effectively solving the problem of inconvenient storage and transportation of the evaporative humidifier is an urgent problem to be solved by those skilled in the art.

SUMMARY

In view of this, a first objective of the present disclosure is to provide an evaporative humidifier, which can effectively solve the problem of inconvenient storage and transportation of the evaporative humidifier. A second objective of the present disclosure is to provide a base of an evaporative humidifier.

a support structure, where the support structure can be detachably disposed on the upper portion of the water tank to support the main unit exposed out of the water tank, and the support structure can be detachably assembled to an upper portion of the main unit or an outer side of the water tank.

In the above technical solution, the main unit can be placed into the water tank, so as to be stored using a water storage space of the water tank. During use, the main unit is supported by the support structure to free up the space of the water tank. Therefore, the above evaporative humidifier can prevent an excessively small capacity of the water tank. Moreover, when transported and stored, it can reduce the size using the water storage space of the water tank to facilitate the transportation and storage. The main unit can be placed upright into the water tank, so as to be accommodated by the water tank. During storage, there is no need to wait for water-containing components such as the internal wet curtain assembly to dry out completely, and the liquid will not flow randomly to damage internal electronic devices. In contrast, if the main unit is placed upside down or tipped over, water inside may flow to a fan and a motor, causing damage to the device. The upper portion of the main unit or the outer side of the water tank is provided with an assembly structure for the support structure, such that the support structure remains assembled together with the main unit or the water tank in a storage state to facilitate transportation and storage in the storage state.

To sum up, the evaporative humidifier can effectively solve the problem of inconvenient storage and transportation of the evaporative humidifier.

In some technical solutions, the water tank includes a tank body and an annular gasket; an upper portion of the tank body is provided with the opening; an inner side of the opening of the tank body is provided with a support bevel; the annular gasket protrudes from the inner side of the opening of the tank body to form the inner protruding structure; the second mounting groove is formed in an upper side of the annular gasket; the annular gasket is provided with an annular extending edge on an outer side of the second mounting groove to be lapped on an end surface of the opening of the tank body and abut against the support surface; and a lower portion of the annular gasket corresponding to the second mounting groove is located in a groove between the support bevel and a wall of the tank body.

In some technical solutions, an elastically movable snap protrusion is disposed on the support structure; the snap protrusion can abut against a corresponding structure in the water tank when entering a snapped position, so as to realize a snap-fit; and an elastic snap portion that extends upward is disposed on the support structure, so as to be snapped onto an inner shoulder of the main unit.

In some technical solutions, the snap protrusion abuts against the support structure via an elastic structure, and the snap protrusion is provided with a manual operating portion exposed on an upper side of the support structure.

In some technical solutions, an upper side and/or a lower side of the elastic snap portion are slopes.

In some technical solutions, the evaporative humidifier includes fasteners that are integrally formed; the fasteners include the elastic snap portion and the snap protrusion; and the two fasteners are opposite to each other and abut against each other via an elastic device that is elastically compressible.

In some technical solutions, a bottom of the main unit is fitted to a bottom of an inner chamber of the water tank.

In some technical solutions, a bottom of the water tank is provided with a traveling mechanism, and the support structure is detachably disposed at the bottom of the water tank to replace the traveling mechanism to support the water tank.

In some technical solutions, a water receiving groove configured to receive water falling from a wet curtain in the main unit is formed in the upper portion of the support structure; and when the upper portion of the support structure cooperates with the bottom of the water tank for mounting, the traveling mechanism is accommodated in the water receiving groove.

In some technical solutions, the main unit includes a housing, a fan, and a wet curtain assembly; an air outlet is formed in a top of the housing; an air inlet corresponding to the wet curtain assembly is formed in a side of a lower portion of the housing; the fan is located at an upper side of the wet curtain assembly; and a window for detachment of the wet curtain assembly is formed in the lower portion of the housing.

To achieve the above second objective, the present disclosure further provides a base of an evaporative humidifier. The base of an evaporative humidifier includes: a water tank, an opening facing upward being formed in an upper portion of the water tank; and a support structure that is detachably disposed on the upper portion of the water tank, where the support structure has a mounting groove configured to support a main body of the evaporative humidifier; the mounting groove is smaller than the opening; and the support structure can be detachably assembled to an outer side of the water tank.

In some embodiments, as shown in FIG. 1, the evaporative humidifier mainly includes the main unit 1, the water tank 2, and the support structure 3. The evaporative humidifier mainly has two states: a storage state, in which the evaporative humidifier is generally not used, and a non-storage state, i.e., an operating state, in which the evaporative humidifier is used for humidification.

In some embodiments, the main unit 1 mainly includes the wet curtain assembly 1-3 and the fan 1-2. The fan 1-2 is configured to accelerate air to flow through the wet curtain assembly 1-3. When the air flows through the wet curtain assembly 1-3, it mixes with water in the wet curtain assembly 1-3, thereby greatly increasing a moisture content in the air. The humidified air flows to ambient air to achieve a humidifying effect. The water in the wet curtain assembly 1-3 is mainly supplied from the water tank 2 via a water guide device. The specific structure of the main unit 1 may refer to the prior art. The water guide device, such as a water pump and a siphon device, may be separately disposed or integrated onto the main unit 1.

In some embodiments, the water tank 2 is mainly configured to store the water, i.e., a liquid used for humidification. The water tank 2 is not limited in terms of capacity, shape and the like. It may be of a cylindrical structure or a square structure, and may be specifically configured as needed.

Herein, the opening 2-1 is formed in an upper portion of the water tank 2. The main unit 1 can be placed into the water tank 2 from the opening 2-1, so as to be accommodated by the water tank 2 to form a storage state. The opening 2-1 generally faces upward. It is to be noted that the main unit 1 may be completely disposed in the water tank 2 to achieve complete storage, or partially disposed in the water tank 2 to achieve partial storage. During the partial storage, for example, the main unit 1 is still accommodated, with a top exposed out of the water tank 2. To take out the main unit 1 conveniently, a side of an upper portion of the main unit 1 may be provided with a grip portion 1-6. Certainly, in the storage state, the grip portion is preferably exposed out of the water tank 2 to facilitate operation. The grip portion 1-6 may be a bracelet, or a recess as shown in FIG. 1.

The main unit 1 may be placed upright into the water tank 2, or tipped over or placed upside down into the water tank 2. To prevent residual water in the main unit 1 from flowing randomly to affect the use of the main unit 1, the main unit 1 is preferably placed upright into the water tank 2 from the opening 2-1. The term "upright" refers to maintaining a placement state as during use, i.e., without rotating the main unit 1, the main unit 1 can be placed into the water tank 2 during storage.

In some embodiments, the support structure 3 supports the main unit 1 between the main unit 1 and the water tank 2 when the main unit 1 is taken out of the water tank 2. At this time, the main unit 1 is taken out of the water tank 2 to free up a water storage space of the water tank 2, thereby ensuring a water storage capacity of the water tank 2 during use. After the main unit 1 moves upward relative to the water tank 2 to expose out of the water tank 2, the main unit 1 is no longer directly supported by the bottom of the water tank 2. Instead, the main unit 1is directly supported by the support structure 3 to enter the operating state. The support structure 3 may be directly supported by the water tank 2 or the ground. Nevertheless, the support structure 3 should be detachably disposed on the upper portion of the water tank 2, such that it can clear the opening 2-1 to facilitate movement of the main unit 1 into or out of the opening 2-1. The main unit 1 is accommodated by the water tank 2 when moving into the opening 2-1. When the main unit 1 moves out of the opening 2-1, the space of the water tank 2 can be freed up to increase the water storage capacity. Moreover, when the main unit 1 moves upward, the support structure 3 can replacethe bottom of the water tank 2 to support the main unit 1, maintaining the main unit 1 on the upper portion, and maintaining the freed space.

In some embodiments, in the storage state, the main unit 1 is accommodated in the water tank 2. At this time, the support structure 3 can be assembled to the upper portion of the main unit 1 or an outer side of the water tank 2. For example, when the main unit 1 is completely accommodated in the water tank 2, the support structure 3 can still be disposed on the upper portion of the water tank 2. That is, in the operating state and the storage state, the support structure 3 has a same mounting position, as well asa same mounting posture. The support structure 3 is only disassembled from the water tank 2 when the main unit 1 moves into or out of the opening 2-1, so as to clear the opening 2-1 of the water tank 2 toensuresmooth passage of the main unit 1. The support structure 3 is preferably disassembled from the water tank 2 via a quick disassembly structure. For example, as shown in FIG. 12, when the top of the main unit 1 is exposed out of the water tank 2, the support structure 3 may be placed on the top of the main unit 1. For ease of mounting, the support structure 3 may be placed upside down on the top of the main unit 1 compared with the operating state. Certainly, the support structure 3 may also be placed upright on the top of the main unit 1.

In some embodiments, the main unit 1 may be placed into the water tank 2, so as to be stored using a water storage space of the water tank 2. During use, the main unit 1 is supported by the support structure 3 to free up the space of the water tank 2. Therefore, the above evaporative humidifier can prevent an excessively small capacity of the water tank 2. Moreover, when transported and stored, it can reduce the size using the water storage space of the water tank 2 to facilitate the transportation and storage.

In some embodiments, the main unit 1 can be placed upright into the water tank 2, so as to be accommodated by the water tank 2. During storage, there is no need to wait for water-containing components such as the internal wet curtain assembly 1-3 to dry out completely, and the liquid will not flow randomly to damage internal electronic devices. In contrast, if the main unit 1 is placed upside down or tipped over, water inside may flow to the fan 1-2 and a motor, causing damage to the device.

In some embodiments, in the actual storage state, some components such as the wet curtain assembly 1-3 may not enter the water tank with a main portion of the main unit 1. The main portion of the main unit 1 includes, for example, a housing.

In some embodiments, the upper portion of the main unit 1 or the outer side of the water tank 2 is provided with an assembly structure for the support structure 3, such that the support structure 3 remains assembled together with the main unit 1 or the water tank 2 in the storage state to facilitate the transportation and storage in the storage state.

To sum up, the evaporative humidifier can effectively solve the problem of inconvenient storage and transportation of the evaporative humidifier.

In some embodiments, as described above, the support structure 3 is disposed on the upper portion of the water tank 2, and may be directly supported by the water tank 2. Alternatively, it may not be directly supported by the water tank 2. For example, the support structure 3 is provided with a plurality of support legs. The plurality of support legs are disposed around the outer side of the water tank 2, such that the support structure 3 is directly supported by the ground. The water tank 2 may be supported by the support structure 3, or may also be directly supported by the ground. For ease of arrangement and to achieve a neat external appearance, the support structure 3 is preferably directly disposed on the upper portion of the water tank 2, so as to be supported by the water tank 2.

In some embodiments, as shown in FIGS. 7-9, the support structure 3 may be placed at a rim of the opening 2-1, so as to be supported by the water tank 2.

In some embodiments, to place the support structure 3 on the water tank 2 better and more stably, the support structure 3 is preferably snapped onto the rim of the opening 2-1. Certainly, to achieve the stable connection, other manners such as a threaded connection and a clamping connection may also be used.

In some embodiments, in the operating state, the main unit 1 is placed on the support structure 3, so as to be supported by the support structure 3. To facilitate supporting and ensure the positional stability, a first mounting groove 3-1 fitted to the bottom of the main unit 1 is formed in an upper portion of the support structure 3, such that the main unit 1 is located and limited by the first mounting groove 3-1, ensuring relatively stable positions of the main unit 1 and the support structure 3. The fit herein may be a clearance fit or an interference fit. The first mounting groove 3-1 may be fitted to the bottom of the main unit 1. It is to be noted that when the water guide device needs to pass through the support structure 3, a hole is correspondingly formed in the support structure 3 to facilitate passage of the water guide device, such as passage of a tube of the water guide device.

In some embodiments, a lower portion of the support structure 3 may cooperate with the rim of the opening 2-1 via the second mounting groove 2-2, so as to realize vertical assembly and prevent horizontal misalignment.

In some embodiments, in the operating state, the air inlet 1-5 of the main unit 1 is generally exposed out of the water tank 2. A channel is generally formed in a lower portion of the main unit 1, for example, to facilitate replacement of the wet curtain assembly 1-3, facilitate mounting of the water guide device, and prevent the air from randomly flowing. Herein, the main unit 1 and the support structure 3 may be assembled via the first mounting groove 3-1 to realize a sealed connection, and the water tank 2 and the support structure 3 may be assembled via the second mounting groove 2-2 to realize a sealed connection.

In some embodiments, to further ensure positional stability of the above structures, the support structure 3 is snap-fitted to the rim of the water tank 2, and/or the support structure 3 is snap-fitted to the main unit 1. That is, the support structure 3 is snap-fitted to at least one of the water tank 2 and the main unit 1. The snap-fit is realized by a buckle, typically an elastic buckle that is equivalent to an elastic snap pin structure.

Specifically, for example, to facilitate uniform arrangement, a snap member between the support structure 3 and the main unit 1, and a snap member between the support structure 3 and the water tank 2 may be disposed on the support structure 3.

In some embodiments, as shown in FIGS. 5 and 6, in consideration of maximizing the water tank 2, the opening 2-1 of the water tank 2 is generally as large as possible. This results ina limited supporting area at the opening 2-1. On this basis, to better support the support structure 3, the opening 2-1 is provided with the inner protruding structure 2-3. The second mounting groove 2-2 is formed in the inner protruding structure 2-3. The support structure 3 is provided with a protrusion 3-2 cooperating with the second mounting groove 2-2, so as to realize a sealed connection and a supporting effect. Specifically, the second mounting groove 2-2 may extend along the rim of the opening 2-1 to form an annular structure, i.e., an annular recess.

In some embodiments, to achieve a better supporting effect, a structure of the support structure 3 located on an outer side of the protrusion 3-2 abuts against the upper portion of the water tank 2 via a support surface 3-3, and is preferably aligned with a wall of the water tank 2.

Specifically, an annular support portion may be formed on the outer side of the protrusion 3-2. The support portion is the annular protrusion 3-2 around the outer side of the protrusion 3-2. The support portion is preferably aligned with the wall of the water tank 2, so as to be directly supported by the wall of the water tank 2.

In some embodiments, the water tank 2 may include the tank body 2-4 and the annular gasket 2-5. An upper portion of the tank body 2-4 is provided with the opening. An inner side of the opening of the tank body 2-4 is provided with the support bevel 2-6. The second mounting groove 2-2 is formed in an upper side of the annular gasket 2-5. An annular extending edge is provided on an outer side of the second mounting groove 2-2 to be lapped on an end surface of the opening of the tank body 2-4. Specifically, the edge may form an inverted snap groove to rest on the rim of the tank body 2-4 with its outer side aligned. The end surface of the opening is an end surface of a wall of the tank body 2-4, and abuts against the support surface 3-3 of the support structure 3. A lower portion of the annular gasket 2-5 corresponding to the second mounting groove 2-2 is located in a groove between the support bevel 2-6 and the wall of the tank body 2-4. Generally, a plurality of support bevels 2-6 are arranged uniformly along the opening of the tank body 2-4 to form a plurality of grooves.

In some embodiments, in the storage state, the main unit 1 is placed into the water tank 2, so as to be supported by the water tank 2. To avoid friction with the inner wall of the water tank 2, the bottom of the main unit 1 may be fitted to a bottom of an inner chamber of the water tank 2. Specifically, an inner bottom wall of the water tank 2 may be provided with a plurality of protruding structures, so as to cooperate with recesses in the bottom of the main unit 1 to form a fitted structure.

In some embodiments, the bottom of the water tank 2 may be provided with a traveling mechanism 2-7 to facilitate movement of the evaporative humidifier in the operating state. The traveling mechanism 2-7 may be, for example, a crawler traveling mechanism or a traveling wheel mechanism. Specifically, a universal wheel traveling mechanism may be used.

On this basis, as shown in FIGS. 9-10, the support structure 3 may be detachably disposed at the bottom of the water tank 2 toreplace the traveling mechanism 2-7 to support the water tank 2. In the storage state, the support structure 3, instead of the traveling mechanism 2-7, is assembled to the bottom of the water tank 2 to support the water tank 2, i.e., indirectly support the main unit 1 in the water tank 2. The support structure 3, as a planar support, does not move randomly, thereby ensuring the positional stability.

In some embodiments, a water receiving groove configured to receive water falling from a wet curtain in the main unit 1 may be formed in the upper portion of the support structure 3. The water receiving groove may be separately provided, and may also be the above first mounting groove 3-1. When the upper portion of the support structure 3 cooperates with the bottom of the water tank 2 for mounting, the traveling mechanism 2-7 is accommodated in the water receiving groove. That is, the traveling mechanism 2-7 may be accommodated using an inner space of the water receiving groove, thereby achieving a better fit and a more compact structure in the storage state.

In some embodiments, an inner side of the bottom of the tank body 2-4 may be provided with an upward protruding boss 2-8, to support the bottom of the main unit in the storage state. An outer side of the bottom of the tank body 2-4 is provided with a recess corresponding to the boss 2-8, to accommodate an upper portion of the traveling mechanism 2-7 to achieve a more compact structure. Specifically, there are four bosses 2-8. To better limit the main unit 1, the protruding structure 2-9 may further be disposed on the boss 2-8. Specifically, for example, a lower portion of the wet curtain assembly 1-3 is provided with a plurality of notches 1-7, each of which is fitted to the protruding structure 2-9.

In some embodiments, generally, the main unit 1 includes the housing 1-1, the fan 1-2, and the wet curtain assembly 1-3. The air outlet 1-4 is formed in a top of the housing 1-1. The air inlet 1-5 corresponding to the wet curtain assembly 1-3 is formed in the side of the lower portion of the housing 1-1. The fan 1-2 is located at an upper side of the wet curtain assembly 1-3. The wet curtain assembly 1-3 is generally cylindrical, such that air from the air inlet 1-5 passes through a peripheral side wall of the wet curtain assembly 1-3 to an inner side of the wet curtain assembly 1-3. The air then flows upward along an extension direction to the fan 1-2, so as to be drawn out by the fan 1-2. Thus, the fan 1-2 discharges high-humidity air outward.

In view of the above mounting arrangement, a window for replacement of the wet curtain assembly 1-3 may be formed in the lower portion of the housing 1-1, so as not to increase more openings.

In some embodiments, as shown in FIGS. 3-4, to facilitate the snap-fit between the support structure and water tank 2, the elastically movable snap protrusion 4-2 is disposed on the support structure 3. The snap protrusion 4-2 may cooperate with the inner protruding structure 2-3 to realize the snap-fit between the support structure 3 and water tank 2 for convenient assembly and disassembly. Specifically, the snap protrusion 4-2 can abut against a lower side of the support bevel 2-6.

The elastically movable snap protrusion 4-2 may elastically move by means of an elastic device, or by means of its own elastic structure, so as to move into or out of a snapped position through the elastic movement. At the snapped position, to overcome an elastic force, the snap protrusion 4-2 elastically moves to separate from the snapped position, thereby releasing the snap-fit between the support structure 3 and the water tank 2. It is to be noted that when the snap protrusion 4-2 elastically moves, the elastic device or the elastic structure 4-5 elastically deforms, thereby allowing the snap protrusion 4-2 to move accordingly. When an external force is removed, the snap protrusion 4-2 will return to an original position under an elastic deformation force.

In some embodiments, the snap protrusion 4-2 may abut against the lower side of the inner protruding structure 2-3, such that the snap protrusion 4-2 abuts against the inner wall of the water tank 2. In this case, the water guide plate 4-4 may be integrated on the snap protrusion 4-2 to guide returned water from a water return hole 3-4 to the inner wall of the tank body 2-4, thereby reducing noise of the falling liquid. Since the snap protrusion 4-2 abuts against the lower side of the inner protruding structure 2-3, the snap protrusion 4-2 needs to extend from the lower side of the inner protruding structure 2-3 to the wall of the water tank 2. In practice, the protruding extent of the inner protruding structure 2-3 decreases as it approaches the inner wall of the water tank 2. Meanwhile, the water guide plate 4-4 is integrated on the snap protrusion 4-2 precisely to meet the requirement that the snap protrusion 4-2 abuts against the inner wall of the water tank 2. With the water guide plate 4-4 integrated on the snap protrusion 4-2, the water guide plate 4-4 may constitute a part of the snap protrusion 4-2 to act for example as a rib, and may also be a snap portion of the snap protrusion 4-2. While abutting against the inner wall of the water tank 2, it abuts against the lower side of the inner protruding structure 2-3. In this case, the lower side of the inner protruding structure 2-3 may be narrower than the water guide plate 4-4, such that a portion of the water guide plate 4-4 not abutting against the inner protruding structure 2-3 may guide the water.

Certainly, the water guide plate 4-4 may also be disposed elsewhere without being integrated on the snap protrusion 4-2. The water return hole 3-4 is generally a hole in the water receiving groove at the wet curtain assembly 1-3. The water receiving groove may be formed in the support structure 3 or in the main unit 1.

In some embodiments, the snap protrusion 4-2 may include the water guide plate 4-4 and two vertical plates respectively located on two sides of the water guide plate 4-4. In this case, a water guide groove is formed between the two vertical plates. It is to be noted that the vertical plate may be disposed perpendicularly or inclined relative to the water guide plate 4-4, and may be specifically arranged as needed. An upper side edge of the vertical plate is preferably inclined to abut against the inner protruding structure 2-3. That is, the vertical plate serves as a main snap portion to achieve a limiting effect.

In some embodiments, to better guide the water, an upper side surface of the water guide plate 4-4 may be inclined to form a slope. The upper side surface gradually descends from a water inlet end to a water outlet end. Specifically, the slope may include an inclined plane and/or an arc surface. Certainly, the slope may entirely employ the arc surface or the plane. The plane herein refers to the inclined plane. Certainly, the slope may employ both the arc surface and the plane.

Specifically, the upper side surface may include a first inclined plane, an arc surface, and a second inclined plane connected sequentially along a fluid direction. An inclination of the first inclined plane is greater than an inclination of the second inclined plane. An inclination of a plane where two side edges of the arc surface are located is greater than the inclination of the first inclined plane. With the arc surface, the liquid on the first inclined plane is quickly guided down. In case of a large flow rate of the returned water, since the inclination of the plane where the two side edges of the arc surface are located is greater than the inclination of the first inclined plane, the liquid flowing out of the first inclined plane is thrown onto the arc surface, to slow down a flow velocity. In case of a small flow rate, the flow velocity is relatively low. At this time, the arc surface can offer a desirable guiding effect, to prevent the poor down-flow effect caused by the excessively low flow velocity. The first inclined plane is directly opposite to the water return hole 3-4, i.e., the water return hole 3-4 is located directly above the first inclined plane.

In some embodiments, the main unit 1 may be included. The wet curtain assembly 1-3 may be disposed on the main unit 1. An elastic snap portion 4-1 that extends upward is disposed on the support structure 3, so as to be snapped onto an inner shoulder of the main unit 1. Specifically, for example, it is snapped onto an inner shoulder of the wet curtain assembly, to achieve the snap-fit between the main unit 1 and the support structure 3. If necessary, the support structure 3 may be detached from the main unit 1 to facilitate accommodation of the main unit 1. For example, after the support structure 3, the main unit 1 and the water tank 2 are all detached, and the main unit 1 can be accommodated in the water tank 2. The support structure 3 merely acts as an intermediate bearing structure in this case.

In some embodiments, for ease of assembly and disassembly, both upper and lower sides of the elastic snap portion 4-1 are slopes. The upper slope is configured to guide deformation of the elastic snap portion 4-1 to enter a snapped position, while the lower slope is configured to guide deformation of the elastic snap portion 4-1 to separate from the snapped position. In the snap-fitted state, the lower slope abuts against the inner shoulder. When an external force is applied between the main unit 1 and the support structure 3, the abutment force therebetween increases. Due to the lower slope, the elastic snap portion 4-1 elastically deforms to separate from the snapped position.

In some embodiments, the snap protrusion 4-2 may abut against the support structure 3 via the elastic structure 4-5. The snap protrusion 4-2 is provided with a manual operating portion 4-3 exposed on an upper side of the support structure 3. During use, a force is applied between the main unit 1 and the support structure 3. For example, the upper portion of the main unit 1 is provided with a snap hole to apply an upward pulling force conveniently, such that the elastic snap portion 4-1 is separated from the snapped position, thereby releasing the snap-fit between the support structure 3 and the main unit 1 for detachment.

By operating the snap protrusion 4-2 via the manual operating portion 4-3, a force is applied to the snap protrusion 4-2. Thus, the snap protrusion 4-2 overcomes the elastic force to separate from the snapped position, and the support structure 3 and the water tank 2 can be detached.

In some embodiments, to facilitate arrangement of the above structures, fasteners 4 that are integrally formed may be provided. Thefasteners 4 include the elastic snap portion 4-1 and the snap protrusion 4-2, which are integrally formed to facilitate uniform arrangement.

Specifically, a main portion of the fastener 4 may be located on the lower side of the support structure 3. Moreover, a window may be formed in the support structure 3, such that the elastic snap portion 4-1 extends to the upper side of the support structure 3. The window is sufficiently large to facilitate movement of the entire fastener 4. By forming another window, the manual operating portion 4-3 is exposed out of the upper side of the support structure 3. The fasteners 4 are in a sliding fit with the support structure 3 via slots, thereby further limiting the movement ranges of the fasteners 4. For ease of assembling the support structure 3 onto the water tank 2, a guiding inclined surface is generally provided on a lower side of the fastener.

In some embodiments, there may be a plurality of fasteners 4. For example, there are two or four fasteners 4. If there are two fasteners 4, the two fasteners 4 are opposite to each other and abut against each other via an elastic device that is elastically compressible, so as to restrict each other.

In some embodiments, a width of the water guide plate 4-4 may be not less than a width of the water return hole 3-4 in a corresponding direction. The width direction refers to a direction perpendicular to a water flow direction on the water guide plate, so as to ensure that water falling from the water return hole 3-4 completely falls on the upper side surface of the water guide plate 4-4.

In some embodiments, a lower end of the wet curtain assembly 1-3 may be snap-fitted to the housing 1-1. Alternatively, the wet curtain assembly 1-3 may be lapped with the housing 1-1, i.e., in a simple supporting relationship, which may be specifically provided as needed.

In some embodiments, the fan 1-2 is fixedly disposed on an upper portion of an inner chamber of the housing 1-1. The air outlet is formed in an upper portion of the housing. The wet curtain assembly 1-3 is accommodated on a lower portion of the inner chamber of the housing 1-1. A honeycomb hole is formed in the lower portion of the housing 1-1 to serve as the air inlet. The housing 1-1 and the wet curtain assembly 1-3 may be not fixedly connected, and no indirect fixed connection is required. They may be in a lapped relationship or in an abutting support relationship.

The wet curtain assembly 1-3 includes a cylindrical wet curtain, an upper seat located on an upper end of the cylindrical wet curtain, and a lower seat located on a lower end of the cylindrical wet curtain. The lower seat is annular, with an upper portion provided with an assembly groove cooperating with the cylindrical wet curtain. The elastic snap portion 4-1 is preferably snapped onto an inner wall of the assembly groove.

In some embodiments, a water pumping device may further be included. The water pumping device is configured to convey the water in the water tank 2 to a water distribution tray on an upper end of the wet curtain assembly 1-3. Certainly, a siphon device may also be used as the water guide device. The water distribution tray may be disposed on the upper seat.

When the water pumping device is provided, a pump body may be disposed in the water tank 2, to guide the water to the water distribution tray via a tube. Alternatively, the pump body may be disposed in the main unit 1. A water inlet tube extends into the water tank 2 to pump the water.
