Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomizer. Background Technology

[0002] An electronic atomizer, also known as an electronic cigarette, is a device that heats and atomizes a liquid to generate an aerosol for users to inhale, simulating the sensation of smoking. A traditional electronic atomizer consists of an atomizing component and a power supply component. The atomizing component contains a reservoir and an atomizing coil. The liquid is stored in the reservoir, and the atomizer has an air inlet and an air outlet, with the atomizing chamber connecting the inlet and outlet. When the user inhales, the power supply component powers the atomizing coil, which heats and atomizes the liquid, generating an aerosol within the atomizing chamber. Simultaneously, outside air enters through the air inlet, carrying the aerosol out through the air outlet for the user to inhale.

[0003] However, it is impossible for users to completely extract the aerosol from the atomizing chamber with each inhalation. Therefore, aerosol residue will remain inside the atomizing chamber. The aerosol residue in the atomizing chamber will turn back into liquid after cooling, which is condensate. If there is too much condensate, it will overflow from the air inlet, flow to the outside of the atomizing component, and then flow into the inside of the power supply component, affecting the consumer experience and the stability of product performance. Utility Model Content

[0004] Therefore, the purpose of this application is to provide an electronic atomizer to solve the problem that in existing electronic atomizers, excessive condensate easily overflows from the air inlet during inhalation, which affects the consumer experience and the stability of product performance.

[0005] According to one aspect of this application, an electronic atomizer is provided, comprising:

[0006] The housing has an air outlet and an oil storage chamber and an airflow channel inside;

[0007] An atomizing component is connected to the housing. The atomizing component has an atomizing chamber and a condensing chamber that are vertically separated. The condensing chamber has an air inlet on its wall. The atomizing chamber includes a first chamber and a second chamber that are interconnected and staggered in the vertical direction. The first chamber is coaxially connected to the airflow channel and the air outlet. The second chamber is connected to the condensing chamber through an air passage. The air passage and the air outlet are also staggered in the vertical direction.

[0008] The side wall of the atomizing chamber is provided with an installation groove, and an atomizing core is provided in the installation groove. The atomizing core has an atomizing surface and an oil inlet surface arranged opposite to each other. The atomizing surface faces the atomizing chamber, and the oil inlet surface is connected to the oil storage chamber.

[0009] In one embodiment, the air inlet and the air outlet are misaligned in the vertical direction.

[0010] In one embodiment, the bottom wall of the atomizing chamber is provided with a first air column, and the air passage penetrates the first air column; and / or, the bottom wall of the condensing chamber is provided with a second air column, and the air inlet penetrates the second air column.

[0011] In one embodiment, the atomizing assembly includes a bracket, the mounting slot is formed within the bracket, the bracket has a partition, the atomizing chamber and the condensation chamber are separated by the partition, and the air passage penetrates the partition.

[0012] In one embodiment, the atomizing chamber is provided with an air guide, and the first chamber and the second chamber are formed by a portion of the surface of the air guide and a portion of the inner surface of the support. The air guide is used to form the second chamber and the side away from the air passage is inclined relative to the vertical direction towards the direction close to the atomizing core.

[0013] In one embodiment, the bracket has an oil inlet chamber and an air exchange groove. The oil storage chamber is connected to the mounting groove through the oil inlet chamber, and the air exchange groove extends from the wall of the oil inlet chamber and is connected to the atomizing chamber.

[0014] In one embodiment, the bracket has a ventilation chamber that is separated from the oil inlet chamber, and the ventilation groove extends through the cavity wall of the ventilation chamber.

[0015] In one embodiment, the bracket is provided with a first sealing element, which is attached to the bracket to close the opening of the ventilation groove facing the first sealing element;

[0016] And / or, the ventilation chamber is provided with a second sealing element, which is attached to the cavity wall of the ventilation chamber to close the opening of the ventilation groove facing the second sealing element.

[0017] In one embodiment, the bracket has an oil suction chamber that is separated from the condensation chamber and communicates with the atomization chamber. The oil suction chamber and / or the condensation chamber are provided with an oil suction element. The end of the ventilation groove away from the oil inlet chamber extends to the wall of the oil suction chamber.

[0018] In one embodiment, the atomizing chamber is provided with multiple limiting plates, all of which form an installation position. The air guide is installed in the installation position and abuts against the limiting plates, so that the air guide can be fixed by the limiting plates. At least a portion of the limiting plates and the surface of the air guide form the cavity wall of the atomizing chamber.

[0019] The aforementioned electronic atomizer, on the one hand, by adding a separate condensation chamber below the atomizing chamber, ensures that the humidity of the atomizing chamber is maintained during inhalation, while most of the condensate can be stored in the atomizing chamber. Even if a large amount of condensate accumulates in the atomizing chamber, only a small amount will overflow into the condensation chamber, thus preventing condensate from overflowing from the air inlet to the outside of the atomizing component. This improves the user experience and ensures the performance stability of the electronic atomizer product. On the other hand, by designing the atomizing chamber to include a vertically offset first... The system consists of a first chamber and a second chamber. The first chamber is coaxially connected to the airflow channel and the air outlet. The second chamber is connected to the condensation chamber through an air passage. The air passage and the air outlet are also staggered in the vertical direction, so that after the outside air enters the atomization chamber through the air passage, it can be temporarily stored in the second chamber before flowing into the first chamber. Then, a large amount of aerosol is carried out from the air outlet along a straight path. This avoids some air being discharged from the air outlet without passing through the atomization surface of the atomizing core. As a result, users can inhale a larger amount of aerosol with each puff, greatly improving the user's vaping experience. Attached Figure Description

[0042] One embodiment of this application provides an electronic atomizer for heating an atomizing liquid stored inside the device to form an aerosol for inhalation by a user.

[0043] The structure of the electronic atomizer in this application will be described below using an electronic cigarette as an example. This embodiment is only used as an example and does not limit the technical scope of this application. It can be understood that in other embodiments, the electronic atomizer of this application is not limited to an electronic cigarette, but can also be any other electronic atomizer that can atomize the atomizing liquid into an aerosol, which is not limited here.

[0044] See Figures 1 to 5 , Figure 1 This paper shows a schematic diagram of the appearance of an electronic atomizer 10 according to one embodiment of the present application. Figure 2 A top view of the electronic atomizer 10 is shown. Figure 3 An explosion diagram of the electronic atomizer 10 is shown. Figure 4 and Figure 5A cross-sectional view of the internal structure of the electronic atomizer 10 is shown. An embodiment of this application provides an electronic atomizing device including a housing 100, an atomizing component 200, and a power supply component (not shown). The atomizing component 200 is disposed within the housing 100 and forms an oil reservoir 104 for storing atomized liquid 30 with the inner wall of the housing 100. The power supply component is connected to the atomizing component 200. The power supply component supplies power to the atomizing component 200, which, under the influence of the electrical energy provided by the power supply component, heats the atomized liquid 30 flowing from the oil reservoir 104 into the atomizing component 200, thereby atomizing the atomized liquid 30 to generate an aerosol for the user to inhale.

[0045] Specifically, in one embodiment, such as Figure 4 and Figure 5 As shown, the housing 100 is along the vertical direction ( Figure 4 The atomizing component 200 is connected to the housing 100 and closes the opening of the housing 100 at one end (in the X direction shown in the diagram). The housing 100 has a mouthpiece 101 at the end away from the opening. The mouthpiece 101 has an air outlet 102 that communicates with the inner cavity of the housing 100. The atomizing component 200 has an air inlet 201 at the end away from the air outlet 102. The air inlet 201 and the air outlet 102 are interconnected. A vent pipe 103 is connected to the inside of the mouthpiece 101, extending from the inner wall of the housing 100 toward the inside of the housing 100. The central axis of the vent pipe 103 is parallel to the central axis of the air inlet 201. The end of the vent pipe 103 away from the air outlet 102 is connected to the atomizing component 200, so that one side of the atomizing component 200 and the inner wall of the housing 100 form an oil storage cavity 104.

[0046] It is understood that an oil storage component may be provided inside the housing 100, and the oil storage chamber 104 is opened inside the oil storage component, which is not limited here.

[0047] Combination Figure 4 and Figure 6 As shown, in one embodiment, the air duct 103 has an airflow channel 103a that runs through both ends and connects the air inlet 201 and the air outlet 102. The atomizing component 200 includes a bracket 220 and an atomizing core 210 electrically connected to the power supply component via a plurality of electrode posts 290. The bracket 220 is connected to the air duct 103 and attached to the inner wall of the housing 100 for fixed connection to the housing 100. The atomizing core 210 is disposed inside the bracket 220. An atomizing chamber 202 is provided inside the bracket 220. The atomizing chamber 202 is connected to the air inlet 201 and is connected to the air outlet 102 via the airflow channel 103a. The atomizing core 210 has an oil inlet surface 210b and an atomizing surface 210a that are arranged opposite to each other. The oil inlet surface 210b is connected to the oil storage chamber 104, and the atomizing surface 210a faces the atomizing chamber 202.

[0048] When the user performs a suction action, causing the atomizing core 210 to be electrically connected to the power supply component, the atomizing liquid 30 flows from the oil storage chamber 104 to the oil inlet surface 210b, and then from the oil inlet surface 210b to the atomizing surface 210a. At the same time, the atomizing core 210 operates, heating the atomizing liquid 30 flowing to the atomizing surface 210a, causing the atomizing liquid 30 to generate an aerosol in the atomizing chamber 202. Outside air enters the atomizing chamber 202 sequentially from the air inlet 201, mixes with the aerosol, and then directly enters the airflow channel 103a, and is then inhaled by the user from the air outlet 102.

[0049] However, as described in the background section, after the atomizing liquid 30 is atomized, aerosol residue inevitably remains inside the atomizing chamber 202. This residual aerosol cools and re-enters the liquid, becoming condensate. Therefore, to prevent excessive leakage of condensate from the atomizing component 200, based on the above embodiments, as follows... Figure 4 and Figure 5 As shown, the bracket 220 also has a condensation chamber 203 vertically positioned above and separated from the atomizing chamber 202. An air inlet 201 is located on the wall of the condensation chamber 203. The atomizing chamber 202 and the condensation chamber 203 are interconnected through an air passage 204. Specifically, in the embodiment shown in the figure, the bracket 220 has a partition 2221, which separates the atomizing chamber 202 and the condensation chamber 203. The air passage 204 passes through the partition 2221. Preferably, both the atomizing chamber 202 and the condensation chamber 203 are provided with oil-absorbing elements 260 made of fiber cotton for absorbing condensate.

[0050] Thus, by adding a condensation chamber 203 at the bottom of the atomizing chamber 202, the humidity of the atomizing chamber 202 is maintained during the inhalation process, while most of the condensate can be stored in the atomizing chamber 202. Even if a large amount of condensate is stored in the atomizing chamber 202, causing the oil suction component 260 to be filled with condensate, only a small amount of condensate will overflow into the condensation chamber 203. This prevents condensate from overflowing from the air inlet 201 to the outside of the atomizing component 200, thereby effectively preventing condensate from entering the power supply component. This increases the service life of the power supply component, reduces the risk of the power supply component starting up on its own, ensures the performance stability of the electronic atomizer 10, and improves the user experience.

[0051] Furthermore, in a preferred embodiment, the air inlet 201 and the air passage 204 are offset in the vertical direction, so that if too much condensate in the atomizing chamber 202 overflows from the air passage 204, it can only drip onto the bottom wall of the condensing chamber 203 and will not leak directly out of the atomizing component 200 along the air inlet 201.

[0052] Furthermore, in a more preferred embodiment, combining Figure 4 and Figure 7 As shown, the bottom wall of the atomizing chamber 202 is provided with a first air column 2222, and an air passage 204 penetrates the first air column 2222. Since the first air column 2222 has a certain height, under normal circumstances, the height of the condensate in the atomizing chamber 202 is lower than the height of the first air column 2222, making it difficult for the condensate in the air intake channel to enter the air passage 204 and leak out by dripping down from the air passage 204. More preferably, the bottom wall of the condensing chamber 203 is provided with a second air column 2231, and an air inlet 201 penetrates the second air column 2231. The function of the second air column 2231 is the same as that of the first air column 2222, and will not be described in detail here. In the embodiment shown in the figure, there are two second air columns 2231, so there are correspondingly two air inlets 201. Of course, the number of second air columns 2231 and air inlets 201 is not limited and can be any number.

[0053] It is worth noting that in the actual use of the existing electronic atomizer 10, most of the air inhaled into the atomization chamber 202 cannot pass through the atomization surface 210a, making it difficult to carry out most of the aerosol. As a result, the amount of aerosol inhaled by the user with each puff is small, which greatly reduces the user's vaping experience.

[0054] To address this issue, in a preferred embodiment, such as Figure 4 and Figure 6 As shown, the atomizing chamber 202 includes a first chamber 202a and a second chamber 202b that are vertically interconnected and staggered. The first chamber 202a is coaxially connected to the airflow channel 103a and the air outlet 102. The second chamber 202b is connected to the condensing chamber 203 through an air passage 204, which is also staggered vertically from the air outlet 102. Simultaneously, the atomizing chamber 202 is positioned along a horizontal direction perpendicular to the vertical direction (…). Figure 4 and Figure 5 An installation groove 205 is provided on one side wall (in the Y direction shown in the figure), and the atomizing core 210 is disposed in the installation groove 205. Preferably, the plane where the atomizing surface 210a is located is parallel to the central axis of the air pipe 103.

[0055] In this way, after the outside air enters the atomizing chamber 202 through the air passage 204, it can be temporarily stored in the second chamber 202b and then flow into the first chamber 202a. Compared with the structure in which the first chamber 202a and the second chamber 202b are not staggered in the vertical direction, a large amount of aerosol can be carried out from the air outlet 102. This avoids some air from being discharged from the air outlet 102 without passing through the atomizing surface 210a of the atomizing core 210. Therefore, it can effectively increase the amount of aerosol mist, so that the user can inhale more mist with each puff, which greatly improves the user's inhalation experience. Furthermore, the first chamber 202a is directly connected to the airflow channel 103a inside the air pipe 103. After the air enters the first chamber 202a, it can carry the aerosol generated in the atomizing chamber 202 out through the air outlet 102 along a vertical straight path with fewer bends. This reduces the loss of atomized gas during the inhalation process, thereby making the aerosol taste purer when the user inhales and further improving the user's inhalation experience.

[0056] Specifically, regarding the atomizing chamber 202 being structured to include a first chamber 202a and a second chamber 202b, an air guide 230, made of an elastic material such as silicone, is provided in the atomizing chamber 202. The first chamber 202a and the second chamber 202b are formed by a portion of the surface of the air guide 230 and a portion of the inner surface of the support 220. More preferably, in order to make it easier for air in the second chamber 202b to gather into the first chamber 202a, the side of the air guide 230 used to form the second chamber 202b and away from the air passage 204 is defined as an air guide surface 231. The air guide surface 231 is inclined relative to the vertical direction in the direction closer to the atomizing core 210.

[0057] By tilting the air guide surface 231 toward the atomizing surface 210a, the air inhaled by the user into the electronic atomizer 10, after entering the air intake channel from the air inlet 201, can bend and gather near the atomizing surface 210a under the guidance of the air guide surface 231 and impact the atomizing surface 210a. This makes it easier for most of the aerosol generated by the atomizing core 210 to be carried out from the air outlet 102 along a vertical straight path by the air gathered next to the atomizing surface 210a.

[0058] Furthermore, such as Figure 6 As shown, a groove can also be made on the side wall of the air guide 230 used to form the first cavity 202a, so that the part of the first cavity 202a near the airflow channel 103a (i.e., the upper part of the first cavity 202a in the figure) has a larger horizontal dimension than the part of the first cavity 202a away from the airflow channel 103a (i.e., the lower part of the first cavity 202a in the figure), which can be more conducive to the rapid flow of atomized gas mixed with aerosol and air.

[0059] For the specific structure of the stent 220, please refer to... Figure 4 , Figure 5 and Figure 7 The support 220 includes an upper support 221, a middle support 222, and a lower support 223 connected in sequence. The upper support 221 and the middle support 222 form a cavity, and the air guide 230 is disposed in the cavity to form an atomizing chamber 202, and as shown... Figure 8 and Figure 9 As shown, multiple limiting plates 2223 are provided on the bottom wall of the middle support 222. All the limiting plates 2223 form an installation position 2224. The air guide 230 is installed in the installation position 2224 and abuts against the limiting plates 2223 so that the air guide 230 can be fixed by the multiple limiting plates 2223. Some of the limiting plates 2223 and the surface of the air guide 230 form the cavity wall of the atomizing chamber 202. The partition 2221 is provided on the middle support 222 or the lower support 223 so that a condensation chamber 203 is formed between the middle support 222 and the lower support 223.

[0060] It is understandable that the material of the air guide 230 is not limited to silicone; it can also be made of plastic, and this is not a limitation. It is also understandable that the structure of the bracket 220 can be an injection-molded integral structure, with a first cavity 202a and a second cavity 202b vertically offset inside. Alternatively, the air guide 230 can be disposed within the integrally molded bracket 220 to form the first cavity 202a and the second cavity 202b, and is not limited to being assembled from the upper bracket 221 and the middle bracket 222, and this is not a limitation either.

[0061] Regarding the structure of the upper bracket 221, in order to control the flow rate of the atomizing liquid 30 into the atomizing core 210, combined with... Figure 6 and Figure 10 As shown, the upper bracket 221 has an oil inlet chamber 2211 with a volume much smaller than that of the oil storage chamber 104. The oil storage chamber 104 is connected to the mounting groove 205 through the oil inlet chamber 2211, so that the atomizing liquid 30 will pass through the oil inlet chamber 2211 before flowing into the atomizing core 210. However, it should be noted that during the use of the electronic atomizer 10, since there is a certain amount of air in the oil inlet chamber 2211, as the atomized liquid 30 in the oil reservoir 104 gradually decreases, the atomized liquid 30 will compress the air in the oil inlet chamber 2211. After being compressed to a certain extent, the air in the oil inlet chamber 2211 will accumulate, which will cause an imbalance between the air pressure in the oil reservoir 104 and the air pressure in the oil inlet chamber 2211. This will hinder the atomized liquid 30 in the oil reservoir 104 from entering the oil inlet chamber 2211, and the final result is that the atomized liquid 30 in the oil reservoir 104 cannot smoothly enter the oil inlet chamber 2211.

[0062] Therefore, in order to solve this problem, such as Figure 10 and Figure 11 As shown, the upper support 221 has a ventilation groove 2212, which extends from the wall of the oil inlet chamber 2211 and connects to the atomizing chamber 202, so that the oil inlet chamber 2211 and the atomizing chamber 202 are connected through the ventilation groove 2212. In this way, the air in the oil inlet chamber 2211, after being compressed by the gradually increasing atomizing liquid 30, can be discharged into the atomizing chamber 202 through the ventilation groove 2212, thereby maintaining the air pressure balance between the oil storage chamber 104 and the oil inlet chamber 2211 and avoiding the phenomenon of poor oil intake.

[0063] However, it should be noted that if the length of the air exchange channel 2212 is short, the air in the oil inlet chamber 2211 can be quickly discharged into the atomizing chamber 202, resulting in a faster air exchange rate. The consequence of the faster air exchange rate is that the atomizing liquid 30 in the oil inlet chamber 2211 is continuously introduced into the atomizing core 210 at a faster speed. When the atomizing liquid 30 entering the atomizing core 210 exceeds the oil-locking capacity of the atomizing core 210, the atomizing liquid 30 will continuously seep out from the atomizing core 210, seriously affecting the user's experience.

[0064] Therefore, in order to solve this problem, the applicant made further improvements to the upper bracket 221, such as... Figure 5 and Figure 11 As shown, the upper bracket 221 also has a ventilation chamber 2213 on the side opposite to the oil storage chamber 104, which is isolated from the oil inlet chamber 2211. The ventilation groove 2212 extends through the cavity wall of the ventilation chamber 2213 along its extension path, causing the ventilation groove 2212 to bend and extend, thereby lengthening the ventilation groove 2212. This slows down the ventilation speed and prevents the atomizing liquid 30 from seeping into the atomizing core 210 too quickly, which would cause leakage.

[0065] Furthermore, in Figure 9 and Figure 10 In the embodiment, the ventilation groove 2212 is formed on the surface of the upper support 221 and the cavity wall surface of the ventilation chamber 2213. In order to reduce the ventilation speed, it is necessary to close the opening of the ventilation groove 2212 on the outer surface of the upper support 221 and the opening on the cavity wall surface of the ventilation chamber 2213, so that the ventilation groove 2212 has a closed and elongated shape. Therefore, in this embodiment, combined with Figure 4 , Figure 12 and Figure 13As shown, the upper bracket 221 is provided with a first sealing element 240, which is also made of elastic material such as silicone. The first sealing element 240 is attached to the surface of the upper bracket 221 to form an oil storage cavity 104 with the inner wall of the housing 100, which serves to seal the atomized liquid 30 in the oil storage cavity 104 and to close the opening of the ventilation groove 2212 on the outer surface of the upper bracket 221 (i.e., the opening of the ventilation groove 2212 facing the first sealing element 240); based on the same function, combined with Figure 5 and Figure 10 As shown, the ventilation chamber 2213 is provided with a second sealing member 250, also made of elastic material such as silicone. The second sealing member 250 is attached to the cavity wall of the ventilation chamber 2213 to seal the opening of the ventilation groove 2212 on the cavity wall of the ventilation chamber 2213 (i.e., the opening of the ventilation groove 2212 facing the second sealing member 250). In a preferred embodiment of this application, in order to further extend the length of the ventilation groove 2212, combined with... Figure 10 and Figure 12 As shown, a sealing groove 2214 is provided on the side of the upper support 221 away from the middle support 222, and the ventilation groove 2212 also extends through the groove wall of the sealing groove 2214. The first sealing member 240 has a protruding sealing part 241 on the side facing the upper support 221. The sealing part 241 is inserted into the sealing groove 2214 to seal the opening of the groove wall of the sealing groove 2214 for the part of the ventilation groove 2212 located in the sealing groove 2214.

[0066] Please see Figure 6 In a preferred embodiment, the surface of the first seal 240 used to form the oil reservoir 104 has an oil guiding surface 242 that is slightly inclined downward relative to the horizontal direction, so that the atomizing liquid 30 can flow more easily into the oil inlet chamber 2211 under the action of gravity.

[0067] It is understandable that if the upper bracket 221 does not have an air exchange chamber 2213, only the first seal 240 can be provided without the second seal 250. If the air exchange groove 2212 is provided inside the upper bracket 221 instead of on the surface of the upper bracket 221, only the second seal 250 can be provided without the first seal 240. The specific configuration can be made according to the specific circumstances, and no limitation is made here.

[0068] Furthermore, based on the above embodiments, such as Figure 11 As shown, the top wall of the upper support 221 is also provided with multiple guide grooves 2215. As shown in the figure, an oil suction component 260 is embedded in the air guide component 230. The oil suction component 260 is set close to the guide groove 2215 so that the condensate can flow along the guide groove 2215 and finally drip onto the oil suction component 260 to be absorbed by the oil suction component 260.

[0069] Additionally, if atomizing liquid 30 or condensate enters the ventilation slot 2212, to prevent the atomizing liquid 30 or condensate from leaking from the ventilation slot 2212 into the atomizing chamber 202 and leaking out along the chamber wall of the atomizing chamber 202, such as... Figure 6 As shown, the bracket 220 has an oil suction chamber 206 that is separated from the condensation chamber 203 and communicates with the atomization chamber 202. In this embodiment, the oil suction chamber 206 is formed by assembling the upper bracket 221 and the middle bracket 222 together; the oil suction chamber 206 is also provided with an oil suction element 260, which, combined with... Figure 13 As shown, the end of the ventilation groove 2212 away from the oil inlet chamber 2211 extends to the cavity wall of the oil suction chamber 206, so that the atomizing liquid 30 or condensate entering the ventilation groove 2212 can drip directly onto the oil suction component 260 and be absorbed by the oil suction component 260 after flowing out of the ventilation groove 2212. This can prevent the atomizing liquid 30 or condensate in the ventilation groove 2212 from leaking out of the ventilation groove 2212 and into the atomizing assembly 200 through the electrode mounting hole.

[0070] Optionally, an oil suction component 260 may be selectively installed inside one or more of the atomizing chamber 202, condensing chamber 203 and oil suction chamber 206. This is not limited, but obviously installing an oil suction component 260 inside all three can minimize the risk of oil leakage.

[0071] Regarding the structure of the 210 atomizer core, combined with Figure 6 and Figure 14 As shown, the atomizing core 210 includes an oil guide body 211 and a heating element 212. The heating element 212 is attached to one side of the oil guide body 211 and has a tab 2122 for abutting against the electrode post 290 to be electrically connected to the power supply assembly. One side of the oil guide body 211 forms an oil inlet surface 210b, and the opposite side, that is, the side where the heating element 212 is attached, forms an atomizing surface 210a. The oil guide is used to guide the atomized liquid 30 in the oil inlet chamber 2211 to the heating element 212, and the heating element 212 is used to heat and atomize the atomized liquid 30.

[0072] As one embodiment, the atomizing core 210 is a ceramic core, meaning the heating element 212 is made of ceramic. Using ceramic allows for smaller aerosol particles, a more delicate aerosol experience, and longer durability and lifespan, as well as better resistance to high temperatures and chemical corrosion. Of course, the material of the wicking body 211 is not limited to ceramic; it can also be made of wicking cotton or other materials, and there is no limitation here.

[0073] As a preferred embodiment, such as Figure 14As shown, in order to improve heating efficiency, the heating element 212 includes at least two heating meshes 2121 that heat up simultaneously, and each pair of adjacent heating meshes 2121 are interconnected by sharing at least one tab 2122. It is understood that the number of heating mesh 2121 is not limited and can be any number of two or more. For example, in the embodiment shown in the figure, there are two heating mesh 2121, which are arranged vertically at intervals. One end of each heating mesh 2121 is connected to each other through a common first electrode tab 2122a. The first electrode tab 2122a forms one electrode of the two heating mesh 2121, such as the positive electrode. The other end of each heating mesh 2121 is connected to each other through a common second electrode tab 2122b. The second electrode tab 2122b forms the other electrode of the two heating mesh 2121, such as the negative electrode. There are two corresponding electrode posts 290. When the heating element 212 needs to be electrically connected to the power supply component, the first electrode tab 2122a abuts against one of the electrode posts 290, and the second electrode tab 2122b abuts against the other electrode post 290, so that the heating element 212 is electrically connected to the power supply component through the two electrode posts 290.

[0074] The power supply component includes a battery, a PCB board connected to the battery, and an airflow sensor connected to the PCB board. For details, please refer to existing technologies, which will not be elaborated here.

[0075] Finally, it should be noted that the electronic atomizer 10 provided in this application may also be without a power supply component, and the electronic atomizer 10 may be connected to an external power source. This can be configured according to specific needs, and there are no limitations here.

[0076] Therefore, the electronic atomizer 10 provided in this application, on the one hand, by setting a condensation chamber 203 at the bottom of the atomization chamber 202, makes it difficult for the condensate in the atomization chamber 202 to leak out of the atomization component 200; on the other hand, by placing the atomizing core 210 on its side, and by making the atomization chamber 202 include a first cavity 202a and a second cavity 202b that are offset in the vertical direction, and by making the air passage 204 and the air outlet 102 also offset in the vertical direction, allows the air entering the atomization chamber 202 to first gather and then flow in the second cavity 202b. The aerosol is carried away through the atomizing surface 210a of the atomizing core 210 and along a straight path without bends, allowing the user to inhale more aerosol and thus greatly improving the inhalation experience. On the other hand, by opening a ventilation groove 2212 and a ventilation chamber 2213 in the upper bracket 221, and by setting a first seal 240 and a second seal 250, the extension path of the ventilation groove 2212 is made longer, thus preventing leakage of the atomizing liquid 30 due to excessively rapid ventilation and reducing the risk of oil leakage.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
