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 create 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 an atomizing coil, and the power supply component provides power to the atomizing coil, heating the liquid in the reservoir to atomize it into an aerosol for the user to inhale.

[0003] Currently, some traditional e-cigarette atomizers use ceramic coils, where the wicking body is made of ceramic, and the heating element is located on the atomizing surface of the wicking body. When the user inhales, outside air passes through the atomizing surface, carrying away the aerosol formed by the heating element heating the atomized liquid, which is then inhaled. However, in actual use, most of the air inhaled into the e-cigarette does not pass through the atomizing surface, thus failing to carry away most of the aerosol. This results in a smaller amount of aerosol inhaled with each puff, significantly reducing the vaping experience. Utility Model Content

[0004] Based on this, the purpose of this application is to provide an electronic atomizer to solve the problem that in existing electronic atomizers, during the inhalation process, the air inhaled into the electronic atomizer cannot carry out most of the aerosol, resulting in a small amount of aerosol inhaled by the user per puff, which reduces the vaping experience.

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

[0006] The housing has an air outlet at one end and an air flow channel and an oil storage chamber for storing atomizing liquid inside.

[0007] An atomizing component is connected to the housing. The atomizing component has a first air inlet and an air intake channel and an atomizing chamber. The air intake channel and the atomizing chamber are interconnected and offset in a vertical direction. One end of the atomizing chamber is connected to the first air inlet through the air intake channel, and the other end is coaxially connected to the airflow channel and the air outlet. The side wall of the atomizing chamber has a mounting groove, and an atomizing core is provided in the mounting groove. The atomizing core has an oil inlet surface and an atomizing surface that are arranged opposite to each other. The oil inlet surface is connected to the oil storage chamber, and the atomizing surface faces the atomizing chamber. The end of the air intake channel away from the first air inlet has an air guide surface, which faces the atomizing surface and is inclined relative to the vertical direction.

[0008] In one embodiment, the atomizing assembly includes a bracket and an air guide disposed within the bracket. The bracket includes a heating cap and a heating base connected to each other. The air guide surface is formed on the air guide, and the air guide surface and the inner wall of the heating base form the air intake channel. The side of the air guide and the inner wall of the heating cap form the atomizing cavity.

[0009] In one embodiment, the side of the air guide used to form the atomizing cavity has a guide block that protrudes relative to the side of the air guide, the guide block has a guide surface that is coplanar with the air guide surface, and the projection of the guide block on the cross-section of the atomizing cavity covers a portion of the atomizing cavity.

[0010] In one embodiment, the heating cover has an oil inlet chamber and an air exchange chamber that are isolated from each other. The oil storage chamber is connected to the mounting groove through the oil inlet chamber. The heating cover also has an air exchange groove that extends from the wall of the oil inlet chamber, through the wall of the air exchange chamber, and to the inner wall of the heating cover to form the atomizing chamber, so that one end of the air exchange groove is connected to the oil inlet chamber and the other end is connected to the atomizing chamber.

[0011] In one embodiment, the heating cover is provided with a heating cover seal, which is attached to the heating cover to close the opening of the ventilation groove facing the heating cover seal.

[0012] And / or, the ventilation chamber is provided with a ventilation seal, at least a portion of which is attached to the cavity wall of the ventilation chamber to close the opening of the ventilation groove toward the ventilation seal.

[0013] In one embodiment, the venting seal has a plurality of spaced-apart sealing ribs, each of the sealing ribs extending circumferentially along the venting seal and closing the opening of the venting groove toward the venting seal, and each pair of adjacent sealing ribs forming an oil reservoir with the cavity wall of the venting chamber.

[0014] In one embodiment, the end of the air exchange groove near the atomizing chamber is defined as the end of the air exchange groove, and at least one oil suction element is provided in the bracket, wherein one of the oil suction elements is disposed close to the end of the air exchange groove and is located at the bottom of the end of the air exchange groove.

[0015] In one embodiment, the atomizing core includes an oil guide body and a heating element. The heating element is attached to one side of the oil guide body and has tabs for electrical connection with a power supply component. The side of the oil guide body attached to the heating element forms the atomizing surface. The heating element includes at least two heating meshes, and each pair of adjacent heating meshes are interconnected by sharing at least one tab.

[0016] In one embodiment, all the heating meshes include a first heating mesh, a second heating mesh, a third heating mesh, and a fourth heating mesh, and the tabs of the heating element include a first tab, a second tab, and a third tab;

[0017] The first heating mesh and the second heating mesh are interconnected via the first electrode tab, which is configured as one of the electrodes of the first heating mesh and the second heating mesh; the third heating mesh and the fourth heating mesh are interconnected via the second electrode tab, which is configured as one of the electrodes of the third heating mesh and the fourth heating mesh; all the heating meshes are also connected together via the third electrode tab, which is configured to form the other electrode of all the heating meshes.

[0018] In one embodiment, the electronic atomizer further includes a power supply component, which has a second air inlet communicating with the first air inlet. The power supply component is movably connected to an air regulating element at the location where the second air inlet is located. The air regulating element is movable relative to the power supply component to change the opening size of the second air inlet.

[0019] The power supply component is further provided with a first limiting block at the location where the second air inlet is opened, and the air regulating element has a second limiting block. The first limiting block is used to abut against the second limiting block to restrict the movement of the air regulating element when the air regulating element fully opens the second air inlet and / or closes the second air inlet.

[0020] The aforementioned electronic atomizer, by placing the atomizing coil in a mounting slot on the side wall of the atomizing chamber, with the atomizing surface of the coil facing the atomizing chamber, and by coaxially connecting the airflow channel and the air outlet of the atomizing chamber, allows the atomizing chamber to directly access the air outlet. Furthermore, by creating an air intake channel in the atomizing assembly that is vertically offset from the atomizing chamber, and having a guide surface that faces the atomizing surface and is inclined relative to the vertical direction, a large amount of air drawn into the electronic atomizer can be gathered and impacted by the guide surface. In this way, most of the aerosol produced by the atomizing coil can be carried out from the air outlet along a straight path by the gathered and impacting air on the atomizing surface, thus preventing some air from being discharged from the air outlet without passing through the atomizing surface. Therefore, the user inhales a larger amount of aerosol with each puff, greatly improving the user's vaping experience. Attached Figure Description

[0045] 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.

[0046] 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 capable of atomizing a liquid into an aerosol, which is not limited here.

[0047] See Figures 1 to 4 , 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 A cross-sectional view of the internal structure of the electronic atomizer 10 is shown. An embodiment of the electronic atomizer 10 provided in this application includes a housing 100, an atomizing component 200, and a power supply component 300. The atomizing component 200 is disposed within the housing 100 and forms an oil reservoir 104 for storing atomized liquid 50 with the inner wall of the housing 100. The power supply component 300 is connected to the atomizing component 200. The power supply component 300 supplies power to the atomizing component 200, which, under the influence of the electrical energy provided by the power supply component 300, heats the atomized liquid 50 flowing from the oil reservoir 104 into the atomizing component 200, thereby atomizing the atomized liquid 50 to generate an aerosol for the user to inhale.

[0048] Specifically, in one embodiment, such as Figure 3 and Figure 4 As shown, the housing 100 is along the vertical direction ( Figure 4The 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). The housing 100 has a nozzle 101 at the end away from the opening, and the nozzle 101 has an air outlet 102 communicating with the inner cavity of the housing 100. The atomizing component 200 has a first air inlet 201 at the end away from the air outlet 102, and the power supply component 300 has a second air inlet 301 at the end away from the air outlet 102, allowing the second air inlet to... The mouthpiece 301, the first air inlet 201 and the air outlet 102 are connected in sequence; a vent pipe 103 extending from the inner wall of the housing 100 toward the inside of the mouthpiece 101 is connected to the inside of the mouthpiece 101. The central axis of the vent pipe 103 is parallel to the central axis of the first air inlet 201, and 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 chamber 104.

[0049] 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.

[0050] Combination Figure 4 and Figure 5 As shown, in one embodiment, the vent pipe 103 has an airflow channel 103a that extends through both ends and connects the first air inlet 201 and the air outlet 102. The atomizing assembly 200 has an atomizing chamber 202. The top of the atomizing chamber 202 is coaxially connected to the airflow channel 103a and the air outlet 102, and the atomizing chamber 202 is aligned along a first horizontal direction (…). Figure 4 and Figure 5 An installation groove 203 is provided on one side wall (in the Y direction shown). An atomizing core 210 is provided in the installation groove 203 and electrically connected to the power supply assembly 300 through a plurality of electrode posts 290. The atomizing core 210 has an atomizing surface 210a and an oil inlet surface 210b arranged opposite to each other on opposite sides. The atomizing surface 210a faces the atomizing chamber 202, so that the plane where the atomizing surface 210a is located is parallel to the central axis of the air pipe 103. The oil inlet surface 210b is away from the atomizing chamber 202 and is connected to the oil storage chamber 104.

[0051] When the user performs a suction action, which electrically connects the atomizing core 210 to the power supply component 300, the atomizing liquid 50 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 50 flowing to the atomizing surface 210a, causing the atomizing liquid 50 to generate an aerosol in the atomizing chamber 202. Outside air enters the atomizing chamber 202 sequentially from the second air inlet 301 and the first 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.

[0052] Thus, it is easy to see from the figure that, through the above design, the atomizing chamber 202 is directly connected to the airflow channel 103a in the air pipe 103. After the external environment enters the atomizing chamber 202, it can carry the aerosol generated in the atomizing chamber 202 out through the airflow channel 103a from the air outlet 102 with fewer bends, thereby reducing the loss of smoke during the inhalation process, and thus making the smoke taste purer and improving the user's inhalation experience.

[0053] Furthermore, as described in the background art, during the actual use of the electronic atomizer 10, most of the air inhaled into the electronic atomizer 10 cannot pass through the atomizing surface 210a, making it difficult to carry out most of the aerosol. This results in the user inhaling less aerosol with each puff, which greatly reduces the user's vaping experience.

[0054] Therefore, based on the above embodiments, as an improvement to the above embodiments, combined with Figure 4 and Figure 6 As shown, the atomizing component 200 also has an air intake channel 204. The bottom end of the atomizing chamber 202 is connected to the first air intake 201 through the air intake channel 204. The air intake channel 204 and the atomizing chamber 202 are connected to each other and are offset in the vertical direction. The end of the air intake channel 204 away from the first air intake 201 has an air guiding surface 231. The air guiding surface 231 faces the atomizing surface 210a and is inclined relative to the vertical direction.

[0055] By opening an air intake channel 204 and tilting the air guide surface 231 of the air intake channel 204 toward the atomizing surface 210a, the air inhaled by the user into the electronic atomizer 10, after entering the air intake channel 204 from the first air intake port 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. As a result, most of the aerosol generated by the atomizing core 210 can be gathered and the air impacting the atomizing surface 210a can be carried out from the air outlet 102 along a vertical straight path. Therefore, the amount of aerosol inhaled by the user with each puff is larger, which better improves the user's vaping experience.

[0056] For a more detailed description of the structure of the atomizing component 200, please refer to [link / reference needed]. Figure 5The atomizing assembly 200 includes a support 220 and an air guide 230 disposed within the support 220. The support 220 includes a heating cap 221 and a heating base 222 connected to each other. The air guide 230 is made of silicone material, and its bottom surface forms the aforementioned air guide surface 231. The air guide surface 231 and the inner wall of the heating base 222 form an air intake channel 204. The side of the air guide 230 and the inner wall of the heating cap 221 form an atomizing cavity 202. Regarding the material of the air guide 230, in one embodiment, the air guide 230 is made of an elastic material such as silicone. Of course, the material of the air guide 230 is not limited to this; it can also be made of plastic material, which is not limited here. It is also understood that the structure of the bracket 220 can be an injection-molded integral structure, which has an atomizing chamber 202 and an air intake channel 204 inside, or the air guide 230 is set in the integrally molded bracket 220 to form an atomizing chamber 202 and an air intake channel 204, and is not limited to being assembled from a heating cover 221 and a heating base 222, nor is it limited here.

[0057] As a further improvement, such as Figure 7 As shown, the side of the air guide 230 used to form the atomizing chamber 202 has a guide block 232 that protrudes from the side of the air guide 230. The guide block 232 has a guide surface 2321 that is coplanar with the air guide surface 231. Since the air guide surface 231 is inclined, the guide surface 2321 is also inclined and has the same inclination angle as the air guide surface 231. Furthermore, the projection of the guide block 232 on the cross-section of the atomizing chamber 202 covers part of the projection of the atomizing chamber 202 on its own cross-section.

[0058] By setting the guide block 232, the air entering the atomizing chamber 202 from the air intake channel 204 can get closer to the atomizing surface 210a. Therefore, it is more conducive to a larger amount of air gathering near the atomizing surface 210a. This can further prevent the air from entering the atomizing chamber 202 from the air intake channel 204 without passing through the atomizing surface 210a and flowing directly out of the airflow channel 103a and the air outlet 102 in the vertical direction.

[0059] Preferably, in order to control the flow rate of the atomizing liquid 50 into the atomizer core 210, such as Figure 4As shown, the heating cover 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 203 through the oil inlet chamber 2211, so that the atomizing liquid 50 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 50 in the oil reservoir 104 gradually decreases, the atomized liquid 50 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 50 in the oil reservoir 104 from entering the oil inlet chamber 2211, and the final result is that the atomized liquid 50 in the oil reservoir 104 cannot smoothly enter the oil inlet chamber 2211.

[0060] Therefore, in order to solve this problem, such as Figure 8 As shown, the heating cover 221 has a ventilation groove 2212, which extends from the wall of the oil inlet chamber 2211 to the wall of the atomizing chamber 202. One end of the ventilation groove 2212 connects to the oil inlet chamber 2211, and the other end connects to the atomizing chamber 202. 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 50, 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.

[0061] 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 atomized liquid 50 in the oil inlet chamber 2211 is continuously introduced into the atomizing core 210 at a faster speed. When the atomized liquid 50 entering the atomizing core 210 exceeds the oil-locking capacity of the atomizing core 210, the atomized liquid 50 will continuously seep out from the atomizing core 210. Since the electrode post 290 passes through the electrode mounting hole opened in the heating base 222, if too much atomized liquid 50 seeps out, the atomized liquid 50 will leak from the electrode mounting hole, seriously affecting the user's experience.

[0062] Therefore, in order to solve this problem, the applicant made a special design to the heating cover 221, such as... Figure 9 and Figure 10As shown, the heating cover 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 50 from seeping into the atomizing core 210 too quickly, which would cause oil leakage.

[0063] Furthermore, in Figure 9 and Figure 10 In the embodiment, the ventilation groove 2212 is formed on the surface of the heating cover 221 and the cavity wall surface of the ventilation chamber 2213. In order to slow down the ventilation speed, it is necessary to close the opening of the ventilation groove 2212 on the outer surface of the heating cover 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 8 and Figure 9 As shown, a heating cap 221 is provided with a heating cap seal 240 made of the same elastic material as silicone. The heating cap seal 240 is attached to the surface of the heating cap 221 to form an oil storage cavity 104 with the inner wall of the housing 100, which serves to seal the atomizing liquid 50 in the oil storage cavity 104 and to close the opening of the ventilation groove 2212 on the outer surface of the heating cap 221 (i.e., the opening of the ventilation groove 2212 facing the heating cap seal 240); based on the same function, combined with Figure 10 and Figure 11 As shown, the ventilation chamber 2213 is provided with a ventilation seal 250, also made of elastic material such as silicone. At least a portion of the ventilation seal 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 ventilation seal 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 heating cover 221 away from the heating base 222, and the ventilation groove 2212 also extends through the groove wall of the sealing groove 2214. The heating cover seal 240 has a protruding sealing part 241 on the side facing the heating cover 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.

[0064] Please see Figure 6In a preferred embodiment, the surface of the heating cap seal 240 used to form the oil reservoir 104 also has an oil guiding surface 242 that is slightly inclined downward relative to the first horizontal direction, so that the atomizing liquid 50 can flow more easily into the oil inlet chamber 2211 under the action of gravity. Similarly, for the structure of the venting seal 250, see also [reference needed]. Figure 11 The ventilation seal 250 has multiple spaced-apart sealing ribs 251. Each sealing rib 251 extends circumferentially along the ventilation seal 250 and closes the opening of the ventilation groove 2212 facing the ventilation seal 250. It can be seen that, through this design, the opening of the ventilation groove 2212 on the cavity wall of the ventilation chamber 2213 is not completely closed, but only closed by the spaced-apart sealing ribs 251. Therefore, the ventilation speed can be moderate, avoiding excessively slow ventilation speed that could lead to poor oil intake. Furthermore, it can be seen that every two adjacent sealing ribs 251 and the cavity wall of the ventilation chamber 2213 form an oil storage groove 252. By forming the oil storage groove 252, if the atomizing liquid 50 leaks into the ventilation chamber 2213, the atomizing liquid 50 can be stored in the oil storage groove 252, thereby preventing the atomizing liquid 50 from leaking out of the ventilation chamber 2213. Similarly, if the heating cover 221 has a sealing groove 2214, the sealing part 241 of the heating cover seal 240 can also be arranged with multiple spaced sealing ribs 251.

[0065] It is understandable that if the heating cover 221 does not have a ventilation chamber 2213, only the heating cover seal 240 can be provided without the ventilation seal 250. If the ventilation groove 2212 is provided inside the heating cover 221 instead of on the surface of the ventilation seal 250, only the ventilation seal 250 can be provided without the heating cover seal 240. The specific configuration can be made according to the specific situation, and no limitation is made here.

[0066] In addition, since the aerosol will generate a lot of condensate after cooling during the use of the electronic atomizer 10, in order to prevent the condensate from leaking downward from the airflow channel 103a, and if the atomizing liquid 50 enters the air exchange slot 2212, in order to prevent the atomizing liquid 50 from leaking from the air exchange slot 2212 into the atomizing chamber 202 and leaking along the chamber wall of the atomizing chamber 202, at least one oil-absorbing element made of fiber cotton is formed in the support 220 of the atomizing assembly 200, so that the oil-absorbing element can absorb the condensate or the atomizing liquid 50, thereby avoiding the problem of atomizing liquid 50 leakage.

[0067] For example, such as Figure 4 and Figure 6In the embodiment shown in the figure, there are multiple oil-absorbing components, including a first oil-absorbing component 260, a second oil-absorbing component 270, a third oil-absorbing component 280, a fourth oil-absorbing component 302, and a fifth oil-absorbing component 303. A first oil-absorbing component 260 is disposed between the heating cap 221 and the oil guide component. The first oil-absorbing component 260 is close to the airflow channel 103a, allowing it to absorb condensate dripping down the inner wall of the airflow channel 103a. A second oil-absorbing component 270 is provided on the bottom wall of the heating base 222, which forms the air intake channel 204. The second oil-absorbing component 270 is used to absorb condensate dripping down the air intake channel 204. The condensate in 4; a third oil suction member 280 is provided between the heating base 222 and the heating cover 221. The end of the ventilation groove 2212 near the atomizing chamber 202 is defined as the end of the ventilation groove. The third oil suction member 280 is set close to the end of the ventilation groove and is located on the bottom wall of the ventilation groove 2212. If there is atomized liquid 50 leaking from the oil storage chamber 104 in the ventilation groove 2212, the third oil suction member 280 can absorb the atomized liquid 50 leaking from the ventilation groove 2212; the fourth oil suction member 302 and the fifth oil suction member 303 are provided in the power supply component 300 to absorb the condensate leaking into the power supply component 300.

[0068] Furthermore, based on the above embodiments, such as Figure 10 As shown, the top wall of the heating cover 221 is also provided with multiple guide grooves 2215, so that the condensate can flow along the guide grooves 2215 and eventually drip onto the first oil suction member 260 for absorption; optionally, as Figure 6 As shown, the bottom wall of the heating base 222, which forms the air intake channel 204, is provided with an air column 2221. The first air inlet 201 penetrates the air column 2221. Since the air column 2221 has a certain height, under normal circumstances, the height of the condensate in the air intake channel 204 is lower than the height of the air column 2221, making it difficult for the condensate in the air intake channel 204 to enter the first air inlet 201 and drip down from the first air inlet 201 and leak out. All of the above designs help to reduce or avoid the occurrence of oil leakage. As shown in the figure, it is a schematic diagram of the structure of the heating base 222 provided in an embodiment of this application. In the embodiment shown in the figure, there are two air columns 2221, so there are also two first air inlets 201. Of course, the number of air columns 2221 is not limited, and correspondingly, the number of first air inlets 201 is also not limited.

[0069] Furthermore, regarding the more specific structure of the heating element 222, such as Figure 13As shown, in one embodiment, the heating base 222 is further provided with two limiting plates 2222 spaced apart along a second horizontal direction (Z direction shown in the figure) perpendicular to the first horizontal direction. The two limiting plates 2222 form mounting positions, and the air guide 230 is disposed in the mounting positions and abuts against the two limiting plates 2222, thereby fixing and limiting the air guide 230 in the second horizontal direction. Preferably, three partitions 2223 spaced apart along the second horizontal direction are also provided between the two limiting plates 2222. It can be seen that the three partitions 2223 are all disposed in the air intake channel 204. Each pair of adjacent partitions 2223 can gather air when air enters the atomizing chamber 202 from the air intake channel 204, which is more conducive to gathering a large amount of air near the atomizing surface 210a to more easily carry out the aerosol.

[0070] Regarding the structure of the 210 atomizer core, combined with Figure 7 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 300. 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 body 211 is used to guide the atomized liquid 50 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 50.

[0071] 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.

[0072] As a preferred embodiment, such as Figure 15As shown, the heating element 212 includes at least two heating mesh sheets 2121, and each pair of adjacent heating mesh sheets 2121 are interconnected by sharing at least one tab 2122. It is understood that the number of heating mesh sheets 2121 is not limited and can be any number of two or more. For example, in the embodiment shown in the figure, there are four heating mesh sheets 2121, including a first heating mesh sheet 2121a, a second heating mesh sheet 2121b, a third heating mesh sheet 2121c, and a fourth heating mesh sheet 2121d. The heating element 212 has three tabs 2122, including a first tab 2122a, a second tab 2122b, and a third tab 2122c. Correspondingly, there are also three electrode posts 290, including a first electrode post 291, a second electrode post 292, and a third electrode post 293. In the specific connection structure between the heating mesh 2121 and the tab 2122, the first heating mesh 2121a and the second heating mesh 2121b are interconnected through the first tab 2122a, which is configured as one of the electrodes of the first heating mesh 2121a and the second heating mesh 2121b, for example, the positive electrode; similarly, the third heating mesh 2121c and the fourth heating mesh 2121d are interconnected through the second tab 2122b, which is configured as one of the electrodes of the third heating mesh 2121c and the fourth heating mesh 2121d, also for example, the positive electrode; all the heating meshes 2121 are also connected together through the third tab 2122c, which forms the other electrode of all the heating meshes 2121, for example, the negative electrode; Figure 14 As shown, when the heating element 212 is electrically connected to the power supply component 300, the first tab 2122a abuts against the first electrode post 291, the second tab 2122b abuts against the second electrode post 292, and the third tab 2122c can abut against the third electrode post 293, or it can be integrally connected to the third electrode post 293 as shown in the figure, so that the heating element 212 is electrically connected to the power supply component 300 through each electrode post 290.

[0073] Thus, it can be seen that by making adjacent heating meshes 2121 share the same tab 2122, the number of conductive contact points can be reduced, thereby reducing the number of electrode posts 290 and achieving the goal of saving costs.

[0074] In terms of the specific structure of the power supply component 300, the power supply component 300 includes a battery, a PCB board connected to the battery, and an airflow sensor connected to the PCB board, etc. For details, please refer to the existing technology, which will not be repeated here.

[0075] However, it should be mentioned that in order to enable or disable the second air inlet 301 to prevent children from accidentally activating the electronic atomizer 10 while playing, or to adjust the amount of air entering the second air inlet 301 to adjust the inhalation taste, in optional embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the power supply component 300 is movably connected to an air regulating element 400 at the location where a second air inlet 301 is provided. The air regulating element 400 can move relative to the power supply component 300 to change the size of the second air inlet 301. In the embodiment shown in the figure, the air regulating element 400 is rotatably connected to the power supply component 300 so that the air regulating element 400 can rotate relative to the power supply component 300 around its own central axis to a first position where the second air inlet 301 is open or a second position where the second air inlet 301 is closed. During the rotation, the opening size of the second air inlet 301 can be adjusted, thereby enabling the adjustment of the amount of air entering the second air inlet 301.

[0076] Furthermore, such as Figure 16 As shown, the power supply component 300 is provided with a first limiting block 304 at the position where the second air inlet 301 is opened, and the air regulating element 400 has a second limiting block 401. When the air regulating element 400 fully opens the second air inlet 301 or when the air regulating element 400 fully closes the second air inlet 301, the first limiting block 304 and the second limiting block 401 abut against each other, thereby limiting the air regulating element 400 to restrict its continued rotation.

[0077] The electronic atomizer 10 provided in this application is assembled as follows:

[0078] First, install the ventilation seal 250 into the ventilation chamber 2213 of the heating cap 221, then install the atomizing core 210 into the mounting groove 203 of the heating cap 221, and then fit the heating cap seal 240 onto the heating cap 221; next, rivet the electrode post 290 through the heating base 222, then install the oil suction component and the air guide component 230 into the heating base 222; finally, snap the heating base 222 and the heating cap 221 together, so that the electrode post 290 is connected to the atomizing core 210 to form the atomizing assembly 200;

[0079] The second step is to inject the atomizing liquid 50 into the housing 100 and then install the atomizing component 200 onto the housing 100.

[0080] The third step is to install the power supply component 300 onto the atomizing component 200, and then install the gas regulating element 400, etc., to finally complete the assembly of the electronic atomizer 10.

[0081] Finally, it should be noted that the electronic atomizer 10 provided in this application may also be without a power supply component 300, 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.

[0082] Therefore, the electronic atomizer 10 provided in this application, on the one hand, by placing the atomizing core 210 on its side and by providing an air guide 230 with an inclined air guide surface 231 in the atomizing assembly 200, allows air to enter the air intake channel 204 and, guided by the air guide 230, gather and impact the atomizing surface 210a of the atomizing core 210. Then, most of the aerosol is carried away along a straight path without bends, thereby greatly improving the vaping experience. On the other hand, by opening an air exchange groove 221 in the heating cap 221... 2. By creating an air exchange chamber 2213 in the heating cap 221 and installing a heating cap seal 240 and an air exchange seal 250, the extension path of the air exchange groove 2212 is lengthened. This prevents leakage of the atomizing liquid 50 due to excessively rapid air exchange, reducing the risk of leakage. Furthermore, by including multiple heating meshes 2121 in the heating element 212 of the atomizing core 210, and connecting adjacent heating meshes 2121 to each other via a common tab 2122, the amount of electrodes used and the number of conductive contact points can be reduced, thereby saving costs. All of these improvements effectively enhance the user experience of the electronic atomizer 10.

[0083] 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.

[0084] 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.
