CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims the benefit of priority from Chinese Patent Application No. 2021112343731, filed on 22 Oct. 2021, the entirety of which is incorporated by reference herein.

TECHNICAL FIELD

The disclosure relates to the technical field of atomization devices, in particular to an atomization assembly and an electronic atomizer.

BACKGROUND

Atomization devices on the market, especially electronic cigarettes, have some problems. For example, in order to meet the needs of users, some electronic cigarettes contain more e-liquid inside, but these electronic cigarettes are difficult to achieve a better anti-leakage performance in the case of being filled with more e-liquid. Electronic cigarettes will have a “grumbling” sound during the inhalation process, which will affect the user’s inhalation experience. In addition, an electronic cigarette is usually only suitable for a few types of e-liquids, resulting in poor applicability of the electronic cigarette.

SUMMARY

The disclosure aims to solve at least one of the technical problems in the existing technology. To this end, the disclosure provides an atomization assembly that has both a larger e-liquid storage capacity and better e-liquid anti-leakage performance. The atomization assembly can reduce noise generated in the use process of the user, and has better applicability.

The disclosure further provides an electronic atomizer with the above-mentioned atomization assembly.

An atomization assembly according to an embodiment in the first aspect of the disclosure includes: a first housing, having a flue pipe in which a smoke outlet passage is arranged; a base, which is connected to the first housing to form an accommodating cavity inside the first housing, the flue pipe being located in the accommodating cavity; a separator, which is arranged in the accommodating cavity to separate the accommodating cavity into a first e-liquid storage cavity and a second e-liquid storage cavity, where the first e-liquid storage cavity is configured to store e-liquid, the separator has at least one e-liquid passage hole which is communicated with the first e-liquid storage cavity and the second e-liquid storage cavity and a first air passage formed inside the separator; an e-liquid storage cotton, which is arranged in the second e-liquid storage cavity and capable of adsorbing e-liquid; and an atomization core, where the e-liquid storage cotton is in contact with a periphery of the atomization core, the atomization core has a second air passage inside, the second air passage and the smoke outlet passage are respectively communicated with the first air passage, and the atomization core is capable of heating the e-liquid to generate smoke which is allowed to enter the second air passage.

The atomization assembly according to this embodiment of the disclosure at least has the following beneficial effects.

According to the atomization assembly provided by the disclosure, a part of the e-liquid is stored in the e-liquid storage cotton, and the remaining part of the e-liquid is stored in the first storage cavity. Therefore, compared to direct injection of all e-liquid into one cavity, the atomization assembly of the disclosure can reduce the amount of e-liquid with higher fluidity in the atomization assembly, and reduce the pressure of the e-liquid, thereby reducing the risk of e-liquid leakage of the atomization assembly (including a risk of leakage into the passage through which the smoke flows, and a risk of leakage to the outside of the base). The e-liquid storage cotton itself has a certain volume. For the same cavity, the e-liquid storage capacity in the cavity with an e-liquid storage cotton is less than that without an e-liquid storage cotton. Compared to the storage of all the e-liquid in the e-liquid storage cotton, the atomization assembly of the disclosure only stores a part of the e-liquid in the e-liquid storage cotton, and thus can store more e-liquid. Therefore, the atomization assembly of the disclosure has both a larger e-liquid storage capacity and better e-liquid anti-leakage performance.

Due to the e-liquid storage cotton, the pressure of the e-liquid near the atomization core is relatively low, such that an e-liquid intake rate of the atomization core will not be too large, and the e-liquid in a liquid state will not easily penetrate into the second air passage of the atomization core. In this way, droplets in a flue can be reduced, and the sound of “grumbling” generated when air flows through the droplets can be reduced, thereby reducing the noise that the user hears in the use process of the atomization assembly.

In addition, by providing the atomization assembly with the e-liquid storage cotton, the applicability of the atomization assembly can be improved. Different types of e-liquids have different viscosities. In the case that the power of the atomization core is constant, an atomization rate of the atomization core is basically unchanged, but rates (that is, an e-liquid intake rate of the atomization core) of e-liquids of different viscosities entering the atomization core are different. Generally, it is usually necessary to make the e-liquid intake rate slightly greater than the atomization rate so as to ensure the continuity of the user’s inhalation and the taste of the smoke. Therefore, one kind of atomization core is usually only suitable for a few kinds of e-liquids. If the atomization assembly is provided with the e-liquid storage cotton, the difference in the rates of different e-liquids entering the atomization core is relatively small. In the case that the e-liquid intake rate of the atomization core is slightly greater than the atomization rate, the atomization assembly is applicable to more e-liquids, and thus has high applicability.

In some embodiments of the disclosure, the atomization assembly further includes an e-liquid filling plug, where the first housing or the base is provided with an e-liquid filling hole which is communicated with the first e-liquid storage cavity, and the e-liquid filling is configured for plugging the e-liquid filling hole.

In some embodiments of the disclosure, the e-liquid filling hole is formed in the base; the first e-liquid storage cavity includes an e-liquid filling passage; a lateral portion of the separator is spaced from an inner wall of the first housing to form the e-liquid filling passage; and the e-liquid filling hole is communicated with one end of the e-liquid filling passage.

In some embodiments of the disclosure, the at least one e-liquid passage hole is formed in the separator at one side facing the e-liquid filling passage.

In some embodiments of the disclosure, the separator includes: a separation portion, where an outer edge of the separation portion is configured to abut against an inner wall of the first housing to separate the accommodating cavity, and the e-liquid passage hole is formed in the separation portion; and a first sleeve portion, which is connected to the separation portion at one side facing the first e-liquid storage cavity and protrudes relative to the separation portion, where an inner cavity of the first sleeve portion serves as a portion of the first air passage.

In some embodiments of the disclosure, the flue pipe is arranged around the first sleeve portion; an outer wall of the first sleeve portion is provided with a first annular rib which abuts against the inner wall of the first housing; and the first annular rib has elasticity.

In some embodiments of the disclosure, the separator further includes a second sleeve portion which is connected to the separation portion at one side facing the second e-liquid storage cavity, and an inner cavity of the second sleeve portion serves as a portion of the first air passage; the e-liquid storage cotton is provided with a positioning passage; and the second sleeve portion and the atomization core are both arranged to pass through the positioning passage.

In some embodiments of the disclosure, the atomization core includes: a core pipe, which is connected to the base and provided with an avoidance port; a fixed seat, which is connected to a bottom of the core pipe; a heating wire, which is connected to the fixed seat and is accommodated inside the core pipe; and an e-liquid guide cotton, which is connected to an inner side of the core pipe, where an inner side of the e-liquid guide cotton serves as a portion of a wall surface of the second air passage, and the avoidance port is configured to allow at least one of the e-liquid guide cotton and the e-liquid storage cotton to pass through, such that the e-liquid guide cotton is in contact with the e-liquid storage cotton; and the heating wire is connected to the e-liquid guide cotton.

In some embodiments of the disclosure, the e-liquid storage cotton is arranged around the core pipe, such that the core pipe is accommodated inside the positioning passage; the deformation seam is communicated with the positioning passage; and a part of the e-liquid guide cotton is arranged inside the deformation seam and clamped by the e-liquid storage cotton.

In some embodiments of the disclosure, a sum of an e-liquid storage capacity of the first e-liquid storage cavity and an e-liquid storage capacity of the second e-liquid storage cavity is not less than 10 ml.

An electronic atomizer according to an embodiment in a second aspect of the disclosure includes the atomization assembly as mentioned above.

The electronic atomizer according to this embodiment of the disclosure at least has the following beneficial effects: it has both a larger e-liquid storage capacity and better e-liquid anti-leakage performance, less noise during use, and better applicability to different e-liquids.

Additional features and advantages of the disclosure will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the disclosure.

In this specification, the schematic representations of the terms above do not necessarily refer to the same embodiment or example. Furthermore, the particular feature, structure, material, or characteristic described may be combined in any suitable manner in any one or more embodiments or examples.

The disclosure provides an atomization assembly. The atomization assembly includes a first housing 204, a base 218, a separator 205, an e-liquid storage cotton 208, and an atomization core 221. In an electronic atomizer 101, the atomization assembly may be used in conjunction with a power supply assembly, which can supply power to the atomization assembly, so as to atomize e-liquid in the atomization assembly.

Referring to FIGS. 2, 3 and 5, the first housing 204 is hollow and is connected to the base 218, thereby forming an accommodating cavity 502 inside the first housing 204. The first housing 204 has a flue pipe 301 which is disposed in the accommodating cavity 502, and the flue pipe 301 has a smoke outlet passage 303 inside. The separator 205 is arranged in the accommodating cavity 502 to separate the accommodating cavity 502 into a first e-liquid storage cavity 304 and a second e-liquid storage cavity 501. A space at a side of the separator 205 facing the base 218 is the second e-liquid storage cavity 501, and a space at the other side of the separator 205 facing the flue pipe 301 is the first e-liquid storage cavity 304. Referring to FIG. 6, the separator 205 is provided with an e-liquid passage hole 606, and the first e-liquid storage cavity 304 and the second e-liquid storage chamber 501 are both communicated with the e-liquid passage hole 606. It should be noted that profiles corresponding to FIGS. 3 and 5 are not cut to the e-liquid passage hole 606, so the e-liquid passage hole 606 is not shown in FIGS. 3 and 5.

In conjunction with FIGS. 3 and 5, the first e-liquid storage cavity 304 and the second e-liquid storage cavity 501 are both configured to store e-liquid (e-liquid is not shown), but the storage methods are slightly different. The e-liquid storage cotton 208 is arranged in the second e-liquid storage cavity 501, the e-liquid located in the first e-liquid storage cavity 304 is directly filled into the first e-liquid storage cavity 304, and the e-liquid located in the second e-liquid storage cavity 501 is absorbed into the e-liquid storage cotton 208. A part of the atomization core 221 is arranged in the second e-liquid storage cavity 501. The e-liquid storage cotton 208 is in contact with the atomization core 221. The atomization core 221 can generate heat, such that the e-liquid in the e-liquid storage cotton 208 generates smoke after being heated. Referring to FIG. 3, the separator 205 has a first air passage 305, the atomization core 221 has a second air passage 306, and both ends of the first air passage 305 are respectively communicated with the second air passage 306 and the smoke outlet passage 303. If a passage through which smoke flows is referred to as a flue, the flue includes a first air passage 305, a second air passage 306, and a smoke outlet passage 303.

The general operating principle of the atomization assembly is as follows: the e-liquid in the e-liquid storage cotton 208 is heated to produce smoke, and a pressure difference generated by the user’s inhalation will drive the smoke to flow through the second air passage 306, the first air passage 305 and the smoke outlet passage 303 in sequence, such that the smoke will eventually flow out of the flue; as the e-liquid in the e-liquid storage cotton 208 is consumed, the e-liquid in the first e-liquid storage cavity 304 will flow from the e-liquid passage hole 606 to the second e-liquid storage cavity 501, and will be absorbed by the e-liquid storage cotton 208 in the second e-liquid storage cavity 501, thereby replenishing the e-liquid to the e-liquid storage cotton 208.

According to the atomization assembly provided by the disclosure, a part of the e-liquid is stored in the e-liquid storage cotton 208, and the remaining part of the e-liquid is stored in the first storage cavity. Therefore, compared to direct injection of all e-liquid into one cavity, the atomization assembly of the disclosure can reduce the amount of e-liquid with higher fluidity in the atomization assembly, and reduce the pressure of the e-liquid, thereby reducing the risk of e-liquid leakage of the atomization assembly (including a risk of leakage into the passage through which the smoke flows, and a risk of leakage to the outside of the base 218). The e-liquid storage cotton 208 itself has a certain volume. For the same cavity, when the e-liquid storage cotton 208 is arranged in the cavity, the e-liquid storage capacity in the cavity is less than that in a case where no e-liquid storage cotton 208 is arranged in the cavity. Compared to the storage of all the e-liquid in the e-liquid storage cotton 208, the atomization assembly of the disclosure only stores a part of the e-liquid in the e-liquid storage cotton 208, and thus can store more e-liquid. Therefore, the atomization assembly of the disclosure has both a larger e-liquid storage capacity and better e-liquid anti-leakage performance.

Due to the e-liquid storage cotton 208, the pressure of the e-liquid near the atomization core 221 is relatively low, such that an e-liquid intake rate of the atomization core 221 will not be too large, and the e-liquid in a liquid state will not easily penetrate into the second air passage 306 of the atomization core 221. In this way, droplets in a flue can be reduced, and the sound of “grumbling” generated when air flows through the droplets can be reduced, thereby reducing the noise that the user hears in the use process of the atomization assembly.

In addition, by providing the e-liquid storage cotton 208 in the atomization assembly, the applicability of the atomization assembly can be improved. Different types of e-liquids have different viscosities. In the case that the power of the atomization core 221 is constant, an atomization rate of the atomization core 221 is basically unchanged, but rates (that is, an e-liquid intake rate of the atomization core) of e-liquids of different viscosities entering the atomization core 221 are different. Generally, it is usually necessary to make the e-liquid intake rate slightly greater than the atomization rate so as to ensure the continuity of the user’s inhalation and the taste of the smoke. Therefore, one kind of atomization core is usually only suitable for a few kinds of e-liquids. If the atomization assembly is provided with the e-liquid storage cotton 208, the difference between the rates of different e-liquids entering the atomization core 221 is relatively small. In the case that the e-liquid intake rate of the atomization core 221 is slightly greater than the atomization rate, the atomization assembly can be applied to more e-liquids, and thus has high applicability.

According to the atomization assembly of the disclosure, a sum of an e-liquid storage capacity of the first e-liquid storage cavity 304 and an e-liquid storage capacity of the second e-liquid storage cavity 501 may be set to be no less than 10 ml, so as to reduce the number of times that the user replaces the atomization assembly or re-adds the e-liquid, thereby improving the convenience in use of the atomization assembly. As mentioned above, since the e-liquid storage cotton 208 is arranged in the atomization assembly, even if the total amount of the e-liquid is greater than 10 ml, leakage of e-liquid is not prone to occur in the atomization assembly. It should be noted that the e-liquid storage capacity of the first e-liquid storage cavity 304 directly depends on the size of the first e-liquid storage cavity 304, and the e-liquid storage capacity of the second e-liquid storage cavity 501 mainly depends on the size of the second e-liquid storage cavity 501 and an adsorption capacity of the e-liquid storage cotton 208 for the e-liquid.

The other structures of the atomization assembly will be described in detail below.

Referring to FIGS. 2 to 4, in some embodiments, the atomization assembly further includes a suction nozzle 202 and a main body plug 201. The suction nozzle 202 is connected to an end of the first housing 204, and configured to contact the user’s mouth. The main body plug 201 is configured to plug the suction nozzle 202 to avoid a hygienic problem caused by the falling of dust into the flue when the atomization assembly is not in use. Referring to FIG. 10, in some embodiments, the suction nozzle 202 and the first housing 204 may also be integrated into one piece.

Referring to FIG. 14, in some embodiments, the atomization core 221 includes a core pipe 211, a fixing ring 212, an e-liquid guide cotton 209 and a heating wire 210. The core pipe 211 is installed on the base 218. The fixing ring 212 is installed at the bottom of the core pipe 211. The fixing ring 212 is connected to the heating wire 210 to fix the position of the heating wire 210, and a pin of the heating wire 210 passes through the fixing ring 212. The e-liquid guide cotton 209 is connected to an inner wall of the core pipe 211, and an inner surface of the e-liquid guide cotton 209 serves as a portion of a wall surface of the second air passage 306. The heating wire 210 is connected to the e-liquid guide cotton 209. The heating wire 210 may be directly connected to the inner surface of the e-liquid guide cotton 209 so as to reduce the difficulty in connection between the heating wire 210 and the e-liquid guide cotton 209. In other embodiments, it may be considered to insert the heating wire 210 into the e-liquid guide cotton 209.

Referring to FIG. 14, a positioning passage 1301 is arranged in the center of the e-liquid guide cotton 209, and a part of the core pipe 211 may be arranged to pass through the positioning passage 1301. The core pipe 211 is provided with an avoidance port 1401, which allows at least one of the e-liquid guide cotton 209 and the e-liquid storage cotton 208 to pass through, so that the e-liquid guide cotton 209 is in contact with the e-liquid storage cotton 208. It may be provided that the e-liquid guide cotton 209 penetrates out of the core pipe 211 and contacts the e-liquid storage cotton 208; or the e-liquid storage cotton 208 is squeezed into the core pipe 211 to contact the e-liquid guide cotton 209; or a part of each of the e-liquid guide cotton 209 and the e-liquid storage cotton 208 is squeezed into the avoidance port 1401, and the two parts are in contact with each other. The e-liquid guide cotton 209 can also adsorb the e-liquid. After the e-liquid guide cotton 209 comes into contact with the e-liquid storage cotton 208, the e-liquid in the e-liquid storage cotton 208 can be transferred to the e-liquid guide cotton 209. The heating wire will generate heat to atomize the e-liquid in the e-liquid guide cotton 209, and the smoke will then enter the second air passage 306.

Referring to FIG. 2, in some embodiments, the e-liquid guide cotton 209 may be set in a cylindrical shape, and the outer wall of the e-liquid guide cotton 209 is in contact with the inner wall of the e-liquid storage cotton 208. Referring to FIG. 14, in some embodiments, a deformation seam 1302 may also be arranged on the e-liquid storage cotton 208. The deformation seam 1302 is communicated with the positioning passage 1301. A part of the e-liquid guide cotton 209 surrounds the outside of the heating wire 210, and the other part of the e-liquid guide cotton 209 penetrates out of the avoidance port 1401 and is arranged in the deformation seam 1302. The part of the e-liquid storage cotton 208, which serves as the wall surface of the deformation seam 1302, can clamp the e-liquid guide cotton 209. In contrast, the method shown in FIG. 14 can increase a contact area between the e-liquid storage cotton 208 and the e-liquid guide cotton 209 and increase an e-liquid intake rate of the atomization core 221.

An e-liquid filling hole 401 may be formed in the first housing 204 or the base 218 so as to add the e-liquid to the atomization assembly. The e-liquid filling hole 401 is communicated with the first e-liquid storage cavity 304, the e-liquid enters the first e-liquid storage cavity 304 from the e-liquid filling hole 401, and a part of the e-liquid will enter the second e-liquid storage cavity 501 through the e-liquid passage hole 606. The atomization assembly further includes an e-liquid filling plug 203, which can plug the e-liquid filling hole 401 to prevent e-liquid leakage. The e-liquid filling plug 203 abuts against the wall of the e-liquid filling hole 401 to seal the e-liquid filling hole 401 and to prevent the e-liquid from leaking from the e-liquid filling hole 401. The e-liquid filling plug 203 may be made of some elastic materials, such as silicone, to improve a sealing effect.

FIG. 4 shows a case where the e-liquid filling hole 401 is formed in the first housing 204. Referring to FIGS. 11 to 13, in some embodiments, a lateral portion of the separator 205 is spaced apart from the inner wall of the first housing 204 to form an e-liquid filling passage 1101; the e-liquid filling passage 1101 serves as a portion of the first e-liquid storage cavity 304; and the e-liquid filling hole 401 is communicated with one end of the e-liquid filling passage 1101. This arrangement may be suitable for cases where the first housing 204 is inconvenient to be provided with an e-liquid filling hole. For example, in FIG. 10, the design shown in FIG. 4 cannot be adopted since the suction nozzle 202 and the first housing 204 are integrated.

In conjunction with FIGS. 11 and 12, in some embodiments, at least one e-liquid passage hole 606 is formed in the separator 205 at one side (e.g., the right side of the separator 205 in FIG. 12) facing the e-liquid filling passage 1101, so as to improve the utilization rate of the e-liquid. If the e-liquid filling hole 606 is not arranged in this side of the separator 205, this part of e-liquid in the e-liquid filling passage 1101 will be unlikely to enter the second e-liquid storage cavity 501, that is, this part of the e-liquid will be wasted.

Referring to FIG. 6, in some embodiments, the separator 205 includes a separation portion 603 and a first sleeve portion 601. The first sleeve portion 601 is hollow, and an inner cavity inside the first sleeve portion 601 serves as a portion of the first air passage 305. The outer edge of the separation portion 603 abuts against the inner wall of the first housing 204. The first e-liquid storage cavity 304 and the second e-liquid storage cavity 501 are respectively arranged on both sides of the separation portion 603. The protruding first sleeve portion 601 cooperates with other components in the atomization assembly conveniently (the flue pipe 301 is arranged around the first sleeve portion 601), thereby positioning the separator 205 in the atomization assembly.

Referring to FIG. 6, in some embodiments, the outer wall of the first sleeve portion 601 is provided with a first annular rib 604, which has elasticity. The first annular rib 604 abuts against the inner wall of the smoke outlet passage 303, thereby preventing the e-liquid from entering the smoke outlet passage 303 from a gap between the flue pipe 301 and the first sleeve portion 601 (that is, preventing the e-liquid from leaking into the smoke outlet passage 303).

Similarly, in some embodiments, the outer edge of the separation portion 603 is provided with a second annular rib 605, which has elasticity. The second annular rib 605 abuts against the inner wall of the first housing 204. The second annular rib 605 is configured to prevent the e-liquid from flowing into the second e-liquid storage cavity 501 from the gap between the separator 205 and the first housing 204. If the e-liquid flows into the second e-liquid storage cavity 501 from the gap between the separator 205 and the first housing 204, the amount of e-liquid entering the second e-liquid storage cavity 501 within the same period of time will increase, which easily causes the actual e-liquid intake rate of the atomization core 221 to be too large and thus affects the normal operation of the atomization assembly. The second annular rib 605 is arranged mainly to ensure that the atomization assembly can work according to a preset working condition.

In some embodiments, the separator 205 may be configured as an integrally formed silicone part. In other embodiments, a plastic part may also be formed by injection molding first, where the shape of the plastic part is similar to that of the separator 205 shown in FIG. 6. However, the plastic part is not provided with the first annular rib 604 and the second annular rib 605, but the plastic part is provided with annular grooves at positions corresponding to the first annular rib 604 and the second annular rib 605. Then, silicone rings are installed in these annular grooves, and used as the first ring rib 604 and the second ring rib 605. The latter arrangement is similar to the fit between a piston and a piston ring.

The separator 205 further includes a second sleeve portion 602. The second sleeve portion 602 is connected to the separation portion 603 at one side facing the second e-liquid storage cavity 501, and an inner cavity of the second sleeve portion 602 serves as a portion of the first air passage 305. The second sleeve portion 602 and the atomization core 221 are connected to each other, and the second sleeve portion 602 is also arranged to pass through the positioning passage. After the separator 205 and the first housing 204 are assembled together, the producer can directly arrange the e-liquid storage cotton 208 around the second sleeve portion 602. The second sleeve portion 602 can enhance a positioning effect on the e-liquid storage cotton 208 and facilitate the assembling of the atomization assembly.

It should be noted that as shown in FIGS. 9 to 12, in some embodiments, the separator 205 is not provided with a second sleeve portion 602, the mutual positioning between the separator 205 and the atomization core 221 can be achieved by a first engagement pipe 904, and both ends of the first engagement pipe 904 are nested with the separator 205 and the atomization core 221 respectively. Similarly, the mutual positioning between the first sleeve portion 601 and the flue pipe 301 can be realized by a second engagement pipe 901.

In addition, referring to FIGS. 2 and 5, in some embodiments, the atomization assembly further includes a positioning sleeve 207 and a lining 206. The positioning sleeve 207 is arranged around the e-liquid storage cotton 208 to improve a positioning effect on the e-liquid storage cotton 208. If the separation portion 603 is set in the shape shown in FIG. 12, the positioning sleeve 207 may not be arranged. The lining 206 is connected to a lower side of the separation portion 603, so as to prevent the e-liquid storage cotton 208 from being adhered with the separator 205 and affecting the convenience of replacing the e-liquid storage cotton 208 (the lining 206 has little effect on the e-liquid storage cotton 208 because the lining 206 can be replaced together).

In order to prevent the e-liquid from leaking out of the base 218, in some embodiments, the atomization assembly further includes a main body seal 213. The main body seal 213 is connected to the base 218 at one side facing the second e-liquid storage cavity 501, and the outer edge of the main body seal 213 is provided with a third annular rib, which abuts against the inner wall of the first housing 204. If it is necessary to enhance an e-liquid anti-leakage effect, a plurality of main body seals 213 may be stacked.

The disclosure further provides an electronic atomizer 101, which includes the above atomization assembly. FIGS. 1 and 8 show two different electronic atomizers 101. Each electronic atomizer 101 includes a power supply assembly and an atomization assembly.

Referring to FIGS. 1 to 5, the power supply assembly includes a transducer 219, a battery 217 and an electrical control board 220, where the transducer 219 is installed in the base 218. The first housing 204 is provided with an air inlet hole 102, and the transducer 219 is located near the air inlet hole 102. When the user takes an inhalation action, air enters the base 218 from the air inlet hole 102. The air flowing from outside to inside will trigger the transducer 219. After the transducer 219 is triggered, a circuit on the electrical control board 220 is closed and the battery 217 supplies power to the atomization core 221, thereby generating smoke. The structure and principle of the transducer 219 belong to the well-known technology in the art, and the circuit connection structure among the transducer 219, the electrical control board 220 and the battery 217 also belongs to the well-known technology in the art, which will not be specifically introduced here.

Referring to FIGS. 2 and 7, the electronic atomizer 101 also includes a first e-liquid-retaining cotton 215 and a second e-liquid-retaining cotton 216 for preventing the leakage of e-liquid to the battery 217, where the first e-liquid-retaining cotton 215 and the second e-liquid-retaining cotton 216 are installed in the base 218. Referring to FIG. 7, the first e-liquid-retaining cotton 215 is provided with a first air hole 701; the second e-liquid-retaining cotton 216 is provided with a second air hole 702; the base 218 is provided with a third air hole 703 and a placement groove 704; and the placement groove 704 is configured to accommodate a bottom of the core pipe. The base 218 has a cavity inside for accommodating the battery 217. After air enters the cavity for accommodating the battery 21 from the air inlet hole 102, it will pass through the first air hole 701, the third air hole 703, and the second air hole 702 in sequence, and enter the atomization core.

In the electronic atomizer shown in FIGS. 1 to 5, a power supply component may be installed in the base 218 of the atomization assembly, which can save the number of parts in the electronic atomizer. Referring to FIGS. 8 to 11, in other embodiments, the power supply assembly further includes a support 902 and a second housing 903. The battery 217, the transducer 219 and the electrical control board 220 are all installed on the support 902. The top of the support 902 is connected to the base 218. The second housing 903 is arranged around the support 902. The air inlet hole 102 is formed in the second housing 903. In the electronic atomizer shown in FIGS. 8 to 11, the power supply assembly is configured as a part that can be flexibly disassembled and assembled relative to the atomization assembly. If the power supply assembly fails, the entire power supply assembly can be removed and maintained directly (or directly replaced with a new power supply assembly after removal). The power supply assembly in FIGS. 8 to 11 is more convenient to maintain, and the disassembly in this way will not affect the overall sealing property of the atomization assembly (because there is no need to remove the base 218). An air flow path design of the support 902 shown in FIGS. 8 to 11 is similar to an air flow path design of the base 218 in FIG. 7, which will not be described in detail here.

The embodiments of the disclosure are described in detail above with reference to the accompanying drawings. However, the disclosure is not limited to the above-mentioned embodiments, and various changes may be made without departing from the purpose of the disclosure within the scope of knowledge possessed by those of ordinary skill in the art. The embodiments in the disclosure and the features in the embodiments may be combined with each other to derive other embodiments not explicitly described.
