FIELD

This application relates to the technical field of electronic vaporization devices, and in particular, to a vaporizer and an electronic vaporization device.

BACKGROUND

A conventional electronic vaporization device such as an e-cigarette is usually designed with a vaporizer. The vaporizer can vaporize an aerosol substrate stored in the vaporizer for a user to inhale. However, liquid leakage usually occurs in the conventional vaporizer. The aerosol substrate (for example, e-liquid) in the vaporizer is prone to leak from the bottom of the vaporizer to the outside of a housing. On the one hand, the aerosol substrate leaking to the outside of the housing exerts a negative impact on the user experience, and on the other hand, the aerosol substrate is prone to permeate into a main unit (that is, a battery end) of the electronic vaporization device, thereby damaging a circuit, a component, and the like in the main unit, and even scrapping the main unit in a severe case.

SUMMARY

In an embodiment, the present invention provides a vaporizer, comprising: a first air inlet; a first air outlet; a first airflow channel, the first airflow channel being in communication with the first air inlet and the first air outlet; a vaporization assembly arranged in the first airflow channel; a second airflow channel, two ends of the second airflow channel separately intersecting the first airflow channel to form a first intersection and a second intersection, the first intersection being located between the first air outlet and the vaporization assembly, and the second intersection being located between the first air inlet and the vaporization assembly; and a capillary liquid absorbing structure connected to the second airflow channel, wherein, when an inhaling action occurs at the first air outlet, accumulated liquid in the first airflow channel that is close to the second intersection enters the second airflow channel through the second intersection so as to be absorbed by the capillary liquid absorbing structure.

Therefore, alleviation of the liquid leakage of the vaporizer and the electronic vaporization device is facilitated, thereby improving the user experience and reducing the risk of damage to a main unit of the electronic vaporization device caused by the permeation of an aerosol substrate into the main unit.

In order to make the objects, technical solutions and advantages of this application clearer, the technical solutions of embodiments of this application will be clearly and comprehensively described in the following with reference to the embodiments of this application. It is apparent that the described embodiments are a part of the embodiments of this application, rather than all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of this application without creative efforts shall fall within the protection scope of this application. The following embodiments and features in the embodiments may be mutually combined if no conflict occurs.

FIG. 1 is a schematic structural diagram a first embodiment of a vaporizer according to this application.

To resolve the technical problem of severe liquid leakage of the vaporizer and the electronic vaporization device in the related art, an embodiment of this application provides a vaporizer 1. The vaporizer 1 includes a first air inlet 11 and a first air outlet 12. The vaporizer 1 further includes a first airflow channel 13, where the first airflow channel 13 is in communication with the first air inlet and the first air outlet 12, and a vaporization assembly 14 is arranged in the first airflow channel 13. The vaporizer 1 further includes a second airflow channel 151, where two ends of the second airflow channel 151 separately intersect with the first airflow channel 13 to form a first intersection 1511 and a second intersection 1512, where the first intersection 1511 is located between the first air outlet 12 and the vaporization assembly 14, and the second intersection 1512 is located between the first air inlet 11 and the vaporization assembly 14.

The vaporizer 1 further includes a capillary liquid absorbing structure 152, and the capillary liquid absorbing structure 152 is connected to the second airflow channel 151. When an inhaling action occurs at the first air outlet 12, accumulated liquid in the first airflow channel 13 that is close to the second intersection 1512 enters the second airflow channel 151 through the second intersection 1512 and is absorbed by the capillary liquid absorbing structure 152. Detailed descriptions are provided below.

In an embodiment, the vaporizer 1 is a component that is configured to vaporize an aerosol substrate in an electronic vaporization device.

The electronic vaporization device to which the vaporizer 1 of this embodiment is applied may be an e-cigarette or the like, and the vaporizer 1 is configured to vaporize e-liquid (that is, an aerosol substrate) for a user to inhale. Certainly, in other embodiments of this application, the electronic vaporization device to which the vaporizer 1 of this embodiment is applied is not limited to a product form of the e-cigarette. For example, the vaporizer 1 of the electronic vaporization device may be further configured to vaporize liquid medicine, or the like. The vaporized liquid medicine is provided for the user to inhale, so as to assist in the user's medicine treatment. The following description is given by using an example in which a product form of the electronic vaporization device to which the vaporizer 1 of this embodiment is applied is the e-cigarette, which is only for description needs and is not intended to constitute a limitation.

Specifically, the vaporizer 1 includes a first air inlet 11, a first air outlet 12, and a first airflow channel 13 that is in communication with the first air inlet 11 and the first air outlet 12. When the user inhales, that is, an inhaling action occurs at the first air outlet, external air enters the first airflow channel 13 from the first air inlet 11 and flows toward the first air outlet 12 along the first airflow channel 13.

Further, a vaporization assembly 14 is arranged in the first airflow channel 13. The vaporization assembly 14 is a component that is configured to vaporize an aerosol substrate in the vaporizer 1. When the user inhales, the air entering the first airflow channel 13 from the first air inlet 11 carries the aerosol substrate vaporized by the vaporization assembly 14 and flows toward the first air outlet 12, and is outputted from the first air outlet 12 for the user to inhale.

Optionally, the vaporization assembly 14 is preferably a porous heating body, which absorbs the aerosol substrate by a capillary force and generates heat to vaporize the aerosol substrate. Preferably, the vaporization assembly 14 may be a porous ceramic heating body, or the like, and a heating film may be further arranged at the bottom of the vaporization assembly. Certainly, in other embodiments of this application, the vaporization assembly 14 may alternatively be such designed that fiber cotton and a heating wire are matched, which is not limited herein.

The vaporizer 1 further includes the second airflow channel 151. The second airflow channel 151 is spaced apart from the first airflow channel 13, and two ends of the second airflow channel 151 separately intersect with the first airflow channel 13 to form a first intersection 1511 and a second intersection 1512.

The vaporizer 1 further includes a capillary liquid absorbing structure 152, and the capillary liquid absorbing structure 152 is connected to the second airflow channel 151 and is configured to absorb accumulated liquid entering the second airflow channel 151.

Because the vaporization assembly 14 is designed in the first airflow channel 13, the aerosol substrate absorbed by the vaporization assembly 14 inevitably remains in the first airflow channel 13. In addition, because a temperature of the vaporized aerosol substrate is relatively high, and a temperature of an inner wall of the first airflow channel 13 is relatively low, the vaporized aerosol substrate undergoes a sharp temperature drop and condenses when contacting the inner wall of the first airflow channel 13, and the condensed aerosol substrate remains in the first airflow channel 13. Therefore, the foregoing factors cause the aerosol substrate to remain in the first airflow channel 13, that is, to form accumulated liquid. However, when too much accumulated liquid remains in the first airflow channel 13, the accumulated liquid inevitably leaks to the outside of the vaporizer 1.

In view of this, in this embodiment, the second airflow channel 151 is designed. The first intersection 1511 is located between the first air outlet 12 and the vaporization assembly 14, and the second intersection 1512 is located between the first air inlet 11 and the vaporization assembly 14. That is, the first intersection 1511 is close to the first air outlet 12 relative to the second intersection 1512. In this way, when an inhaling action occurs at the first air outlet 12, an air flow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13, air pressure of the first airflow channel 13 at the first intersection 1511 is less than air pressure of the second airflow channel 151 at the first intersection 1511, and air pressure of the first airflow channel 13 at the second intersection 1512 is greater than air pressure of the second airflow channel 151 at the second intersection 1512. Therefore, a pressure difference between the first airflow channel 13 and the second airflow channel 151 at the second intersection 1512 drives accumulated liquid in the first airflow channel 13 that is close to the second intersection 1512 to enter the second airflow channel 151 through the second intersection 1512 and be absorbed by the capillary liquid absorbing structure 152 to reduce the accumulated liquid in the first airflow channel 13. Therefore, alleviation of the liquid leakage of the vaporizer 1 is facilitated and the user experience is improved.

It should be noted that, when an inhaling action occurs at the first air outlet 12, the external air enters the first airflow channel 13 from the first air inlet 11. The air flow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13. In addition, part of the air entering the first airflow channel 13 from the first air inlet 11 flows into the second airflow channel 151 from the second intersection 1512, and the air in the second airflow channel 151 converges from the first intersection 1511 to the first airflow channel 13, to form a complete airflow path, as shown by dashed arrows in FIG. 1. That is, only when an inhaling action occurs at the first air outlet 12, a pressure difference is generated between the first airflow channel 13 and the second airflow channel 151 at the second intersection 1512. Therefore, the accumulated liquid in the first airflow channel 13 is driven to flow into the second airflow channel 151 through the second intersection 1512. When an inhaling action does not occur at the first air outlet 12, that is, when the user does not inhale, air pressure in the first airflow channel 13 is about one standard atmospheric pressure, namely, about 101.325 kPa, and an air pressure difference between the first airflow channel and the second airflow channel 151 is not obvious. In this case, the second airflow channel 151 absorbs a relatively limited amount of accumulated liquid in the first airflow channel 13.

In addition, in this embodiment, the second airflow channel 151 is configured to cooperate with the capillary liquid absorbing structure 152 to absorb the accumulated liquid in the first airflow channel 13, and is not a cavity used for storing the aerosol substrate of the vaporizer 1. For example, in the electronic vaporization device in the product form of an e-cigarette, an e-liquid cavity is usually designed in the vaporizer 1 to store e-liquid (that is, the aerosol substrate).

The first air inlet 11 and the first air outlet 12 of the vaporizer 1 in this embodiment may be spaced apart in a straight-line direction, that is, the vaporizer 1 in this embodiment is designed in a straight liquid form. Certainly, in other embodiments of this application, the vaporizer 1 may alternatively be designed in other forms than the straight liquid form, which is not limited herein.

In an embodiment, the second airflow channel 151 is connected to the capillary liquid absorbing structure 152, and is configured to absorb the accumulated liquid entering the second airflow channel 151 from the second intersection 1512.

Further, the capillary liquid absorbing structure 152 includes a plurality of capillary grooves 1521, and the capillary grooves 1521 can absorb and store the accumulated liquid entering the second airflow channel 151 from the second intersection 1512 by the capillary force, as shown in FIG. 1. In addition, the plurality of capillary grooves 1521 are spaced apart sequentially in an extension direction of the second airflow channel 151 and are in communication with the second airflow channel 151, where the capillary grooves 1521 that are relatively close to the second intersection 1512 are preferentially configured to absorb and store accumulated liquid entering the second airflow channel 151. A specific structural design and implementation of the capillary groove 1521 are described below.

Still referring to FIG. 1, in an embodiment, the first airflow channel 13 includes an air outlet channel 131 and a vaporization cavity 132, where a vaporization assembly 14 is arranged in the vaporization cavity 132. The air outlet channel 131 is in communication with the vaporization cavity 132 and the first air outlet 12, and the vaporization cavity 132 is further in communication with the first air inlet 11. That is, the first air outlet 12, the air outlet channel 131, the vaporization cavity 132, and the first air inlet 11 are sequentially in communication with each other.

A cross-sectional area of the air outlet channel 131 is less than a cross-sectional area of the vaporization cavity 132. When an air flow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13, a cross-sectional area of the air outlet channel 131 is relatively small, a flow velocity of the air flow in the air outlet channel 131 is relatively high, and correspondingly the air pressure is relatively low. Increase in a pressure difference between the air outlet channel 131 and the vaporization cavity 132 is facilitated, to make it convenient for the vaporized aerosol substrate to be better provided for the user to inhale.

Cross-sections of both the air outlet channel 131 and the vaporization cavity 132 are perpendicular to their respective extension directions. In addition, an extension direction of the air outlet channel 131 is defined as a direction extending from the vaporization cavity 132 to the first air outlet 12, and an extension direction of the vaporization cavity 132 is defined as a direction extending from the first air inlet 11 to the air outlet channel 131. For example, in the vaporizer 1 in the straight liquid form shown in FIG. 1, the extension directions of the air outlet channel 131 and the vaporization cavity 132 are both the direction from the first air inlet 11 to the first air outlet 12.

In addition, the first intersection 1511 is arranged in the air outlet channel 131, and the second intersection 1512 is arranged in the vaporization cavity 132. In this way, when the air flow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13, the air pressure of the air outlet channel 131 is less than the air pressure of the second airflow channel 151, and the air in the second airflow channel 151 flows into the air outlet channel 131 through the first intersection 1511; and the air pressure of the vaporization cavity 132 is greater than the air pressure of the second airflow channel 151, and the air in the vaporization cavity 132 flows into the second airflow channel 151 through the second intersection 1512, to form the foregoing complete airflow path.

Certainly, in other embodiments of this application, when an inhaling action occurs at the first air outlet 12, the air flow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13. Therefore, in the direction from the first air inlet 11 to the first air outlet 12, the air pressure in the first airflow channel 13 is represented as gradually decreasing. In view of this, the first intersection 1511 and the second intersection 1512 may alternatively be both arranged in the air outlet channel 131 or may be both arranged in the vaporization cavity 132. Provided that it is ensured that the first intersection 1511 is close to the first air outlet 12 relative to the second intersection 1512, a design for alleviating the liquid leakage of the vaporizer 1 in this embodiment of this application may be implemented. In an exemplary embodiment, the second intersection 1512 is located at the bottom of the vaporization cavity 132, so that the accumulated liquid at the bottom of the vaporization cavity 132 may be absorbed by the capillary liquid absorbing structure 152 along the second airflow channel 151 during inhaling.

Specifically, when the air flow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13, air pressure in the vaporization cavity 132 is P1, air pressure in the air outlet channel 131 is P2, and air pressure in the second airflow channel 151 is P3, where P1 is greater than P3, and P3 is greater than P2.

The air pressure of the vaporization cavity 132 is greater than the air pressure of the second airflow channel 151. A pressure difference between the vaporization cavity 132 and the second airflow channel 151 at the second intersection 1512 drives the accumulated liquid in the vaporization cavity 132 that is close to the second intersection 1512 to enter the second airflow channel 151 through the second intersection 1512 and be absorbed by the capillary liquid absorbing structure 152.

In an embodiment, a volume of accommodation space in the second airflow channel 151 and the capillary liquid absorbing structure 152 is less than a volume of accommodation space in the vaporization cavity 132. Accommodation space is defined as space used by a cavity to store the air and the aerosol substrate. A volume of the accommodation space in the second airflow channel 151 and the capillary liquid absorbing structure 152 is relatively small. When the air flow from the first air inlet 11 to the first air outlet is generated in the first airflow channel 13, a flow velocity of the air flow in the second airflow channel 151 and the capillary liquid absorbing structure 152 is relatively high, and correspondingly the air pressure is relatively low. Increase in the pressure difference between the second airflow channel 151 and the vaporization cavity 132, that is, increase in a force that drives the accumulated liquid in the vaporization cavity 132 to enter the second airflow channel 151 is facilitated, and reduction in the accumulated liquid in the first airflow channel 13, especially reduction in the accumulated liquid at the bottom of the vaporization cavity 132 is further facilitated, thereby alleviating the liquid leakage of the vaporizer 1 and improving the user experience.

In addition, the second airflow channel 151 is spaced apart from the first airflow channel 13. Specifically, the second airflow channel 151 is spaced apart from the air outlet channel 131 and the vaporization cavity 132, and the second airflow channel 151 is in communication with the air outlet channel 131 and the vaporization cavity 132 through the first intersection 1511 and the second intersection 1512. Spacing apart is helpful to ensure the pressure difference between the second airflow channel 151 and each of the air outlet channel 131 and the vaporization cavity 132, to ensure that there is a sufficient pressure difference to drive the accumulated liquid in the vaporization cavity 132 to enter the second airflow channel 151, and to further ensure the formation of the foregoing complete airflow path.

Optionally, a partition 16 may be arranged between the second airflow channel 151 and the first airflow channel 13, as shown in FIG. 1, so that the second airflow channel 151 is spaced apart from the first airflow channel 13, which is not limited herein.

It should be noted that, the vaporizer 1 may further include a leak-proof cavity 15, the second airflow channel 151 and the capillary liquid absorbing structure 152 are arranged in the leak-proof cavity 15, the leak-proof cavity 15 is spaced apart from the first airflow channel 13, and the leak-proof cavity 15 intersects with and is in communication with the first airflow channel 13 through the first intersection 1511 and the second intersection 1512 separately.

Certainly, in other embodiments of this application, the second airflow channel 151 and the capillary liquid absorbing structure 152 may alternatively be designed as being integrally formed in the vaporizer 1, which is described below, instead of additionally designing a leak-proof cavity 15 in the vaporizer 1 and then arranging the second airflow channel 151 and the capillary liquid absorbing structure 152 in the leak-proof cavity 15, as described above.

In summary, two ends of the second airflow channel of the vaporizer provided in this application separately intersect with the first airflow channel to form a first intersection and a second intersection, where the first intersection is located between the first air outlet and the vaporization assembly, and the second intersection is located between the first air inlet and the vaporization assembly. That is, the first intersection is close to the first air outlet relative to the second intersection. In this way, when an inhaling action occurs at the first air outlet, an air flow from the first air inlet to the first air outlet is generated in the first airflow channel, air pressure of the first airflow channel at the first intersection is less than air pressure of the second airflow channel at the first intersection, and air pressure of the first airflow channel at the second intersection is greater than air pressure of the second airflow channel at the second intersection. Therefore, a pressure difference between the first airflow channel and the second airflow channel at the second intersection drives accumulated liquid in the first airflow channel that is close to the second intersection to enter the second airflow channel through the second intersection and be absorbed by the capillary liquid absorbing structure to reduce the accumulated liquid in the first airflow channel, especially the accumulated liquid at the bottom of the vaporization cavity. Therefore, alleviation of the liquid leakage of the vaporizer and the electronic vaporization device is facilitated, thereby improving the user experience and reducing the risk of damage to a main unit of the electronic vaporization device caused by the permeation of an aerosol substrate into the main unit.

The vaporizer 1 further includes a leak-proof component 18, the leak-proof component 18 is arranged in the housing 17, at least part of the first airflow channel 13 is provided in the leak-proof component 18, and a vaporization assembly 14 is arranged in the first airflow channel in the leak-proof component 18. The vaporization assembly 14 is described in the foregoing embodiment, and details are not repeated herein.

In an embodiment, the leak-proof component 18 includes a second air inlet 181 and a second air outlet 182, and the first airflow channel 13 in the leak-proof component 18 is in communication with the second air inlet 181 and the second air outlet 182, as shown in FIG. 4. The second air outlet 182 is in communication with the first air outlet 12 through a portion of the first airflow channel 13 outside the leak-proof component 18, as shown in FIG. 3. Similarly, the second air inlet 181 is in communication with the first air inlet 11 through the portion of the first airflow channel 13 outside the leak-proof component 18, so that the first airflow channel 13 in the leak-proof component 18 is in communication with the first air inlet 11 and the first air outlet 12.

Further, a liquid storage cavity 19 is further provided in the housing 17 of the vaporizer 1, and is configured to store the to-be-vaporized aerosol substrate. Preferably, the liquid storage cavity 19 is adjacent to and surrounds an outer periphery of the first airflow channel 13 between the first air outlet 12 and the second air outlet 182. The liquid storage cavity 19 is in communication with the leak-proof component 18 and is further in communication with the vaporization assembly 14 in the leak-proof component 18, so that the aerosol substrate in the liquid storage cavity 19 can be heated and vaporized by the vaporization assembly 14, as shown in FIG. 3.

In an embodiment, a vacant portion 183 is arranged inside the leak-proof component 18. An inner wall of the leak-proof component 18 of the vacant portion 183 and an inner wall of the housing 17 surround and form the first airflow channel 13 provided in the leak-proof component 18, an outer wall of the leak-proof component 18 and the inner wall of the housing 17 surround and form the second airflow channel 151. In addition, the capillary liquid absorbing structure 152 is arranged in space surrounded and formed by the outer wall of the leak-proof component 18 and the inner wall of the housing 17, as shown in FIG. 4. The housing 17 is omitted in FIG. 4.

Certainly, in other embodiments of this application, the vacant portion 183 of the leak-proof component 18 includes a housing structure independent of the housing 17, and can also surround and form the first airflow channel 13 provided in the leak-proof component 18 without the aid of the inner wall of the housing 17. Similarly, a portion of the leak-proof component 18 in the second airflow channel 151 may also include a housing structure independent of the housing 17, and can also surround and form the second airflow channel 151 together with the outer wall of the leak-proof component 18, which is not limited herein.

Still referring to FIG. 4, further, a dike 184 is arranged on the outer wall of the leak-proof component 18, and the dike 184 abuts against the inner wall of the housing 17. The dike 184 is configured to separate the second airflow channel 151 from the first airflow channel 13, so that the second airflow channel 151 is spaced apart from the first airflow channel 13. In addition, a first communication groove 185 is provided on a portion of the dike 184 corresponding to the first intersection 1511, so that the first airflow channel 13 intersects with the second airflow channel 151 to form the first intersection 1511. A second communication groove 186 is provided on a portion of the dike 184 corresponding to the second intersection 1512, so that the first airflow channel 13 intersects with the second airflow channel 151 to form the second intersection 1512. The second communication groove 186 may also be a groove body similar to a capillary groove, which also absorbs the accumulated liquid in the first airflow channel 13 by the capillary force.

FIG. 4 shows a situation in which the vaporization cavity 132 and part of the air outlet channel 131 of the first airflow channel 13 are provided in the leak-proof component 18. The first communication groove 185 is provided corresponding to the air outlet channel 131 in the leak-proof component 18, and the second communication groove 186 is provided corresponding to the vaporization cavity 132 in the leak-proof component 18.

In addition, FIG. 4 further shows a situation in which a second airflow channel 151 and a capillary liquid absorbing structure 152 are arranged on each of two opposite sides of the first airflow channel 13 in the leak-proof component 18. Further, second airflow channels 151 and capillary liquid absorbing structures 152 on the two sides of the first airflow channel 13 in the leak-proof component 18 are preferably arranged in mirror symmetry.

Further, each of two sides of the leak-proof component 18 in a predetermined direction is provided with a first intersection 1511 and a second intersection 1512. In addition, each of the two sides of the leak-proof component 18 in the predetermined direction is provided with a first communication groove 185 and a second communication groove 186 that are provided corresponding to the first intersection 1511 and the second intersection 1512. The first airflow channel 13 in the leak-proof component 18 runs through the leak-proof component 18 in the predetermined direction, and is further in communication with the second airflow channels 151 on the two sides in the predetermined direction. The predetermined direction (as shown by an arrow X in FIG. 4) is perpendicular to a relative direction (as shown by an arrow Y in FIG. 4) of the second airflow channels 151 on the two sides of the first airflow channel 13 in the leak-proof component 18, and is perpendicular to an extension direction (as shown by an arrow Z in FIG. 4) of the first airflow channel 13 in the leak-proof component 18.

Still referring to FIG. 4, in an embodiment, a plurality of capillary grooves 1521 surrounding an outer periphery of the first airflow channel 13 are provided on the outer wall of the leak-proof component 18, and the capillary grooves 1521 can absorb and store the accumulated liquid entering the second airflow channel 151 from the second intersection 1512 by the capillary force.

Specifically, a plurality of fins 1522 surrounding the outer periphery of the first airflow channel 13 are arranged on the outer wall of the leak-proof component 18, and the capillary grooves 1521 are formed between the adjacent fins 1522. In addition, the fin 1522 abuts against the inner wall of the housing 17 to ensure that the capillary groove 1521 can absorb and store the accumulated liquid by the capillary force.

Further, the plurality of capillary grooves 1521 are spaced apart and are parallel to each other in an extension direction of the second airflow channel 151. After the capillary grooves 1521 that are relatively close to the second intersection 1512 are filled up with the accumulated liquid, the capillary grooves 1521 that are relatively far away from the second intersection 1512 continue to absorb the accumulated liquid until a storage amount of the accumulated liquid in the plurality of capillary grooves 1521 reaches saturation. In addition, after the storage amount of the accumulated liquid in the plurality of capillary grooves 1521 reaches saturation, the leak-proof component 18 is optionally detached for cleaning, so as to be used again, or the vaporizer 1 is optionally replaced with a new one, which is not limited herein.

It should be noted that, a portion of the leak-proof component 18 where the second airflow channel 151 and the capillary liquid absorbing structure 152 are located may be a detachable structure. In this way, the second airflow channel 151 and the capillary liquid absorbing structure 152 can be easily assembled into the leak-proof component 18, and it is also convenient to clean the leak-proof component 18 as described above.

Certainly, in other embodiments of this application, the portion of the leak-proof component 18 where the second airflow channel 151 and the capillary liquid absorbing structure 152 are located and the original leak-proof component 18 may alternatively be an integral structure and cannot be disassembled or assembled, which is not limited herein.

Reference is made to FIG. 5 and FIG. 6. FIG. 5 shows a situation of accumulated liquid in the first airflow channel 31 when the quantity of inhaling of the user reaches 60, 90 and 120 according to a conventional vaporizer 3. FIG. 6 shows a situation of accumulated liquid in the first airflow channel 13 when the quantity of inhaling of the user reaches 60, 90 and 120 according to the vaporizer 1 of this embodiment. In addition, FIG. 6 further shows a situation in which the capillary liquid absorbing structure 152 absorbs the accumulated liquid when the quantity of inhaling of the user reaches 60, 90 and 120 according to the vaporizer 1 of this embodiment. It can be seen that the accumulated liquid in the first airflow channel 13 of the vaporizer 1 of this embodiment is significantly reduced.

In summary, in the vaporizer provided in this application, a portion of the first airflow channel that is in communication with the first intersection is close to the first air outlet relative to a portion of the first airflow channel that is in communication with the second intersection in an extension direction of the first airflow channel. In this way, when the user inhales, an air flow from the first air inlet to the first air outlet is generated in the first airflow channel, and air pressure of a portion of the first airflow channel that is in communication with the second intersection is greater than air pressure at the second intersection of the second airflow channel. That is, there is a pressure difference between two sides of the second intersection, and the pressure difference between the two sides of the second intersection drives the accumulated liquid in the first airflow channel to flow into the second airflow channel through the second intersection and be absorbed by the capillary liquid absorbing structure, to reduce the accumulated liquid in the first airflow channel, especially to reduce the accumulated liquid at the bottom of the vaporization cavity. Therefore, alleviation of the liquid leakage of the vaporizer is facilitated and the user experience is improved.

The electronic vaporization device further includes a first airflow channel 13, where the first airflow channel 13 is in communication with the first air inlet 11 and the first air outlet 12, and a vaporization assembly 14 is arranged in the first airflow channel 13.
