[0002] An electronic atomization device is an electronic device that can atomize the atomization liquid such as tobacco oil and liquid medicine stored in it into an aerosol through electric heating. Currently, the electronic atomization devices on the market usually include an atomizer for generating aerosols and a power supply component for providing electrical energy to the atomizer. As an important component of the electronic atomization device, the atomizer has always been the focus of research by technical personnel in this field.

[0003] In related technologies, atomized liquid is usually stored in an atomizer. However, most atomizers currently on the market are disposable products.

[0023] Compared with the prior art, this application has at least the following beneficial effects:

[0024] 1. In the technical solution of the present application, a liquid injection through hole connected to the storage chamber is provided at the top of the liquid storage cup, the suction nozzle body is detachably connected to the top of the liquid storage cup, and a sealing member for sealing the liquid injection through hole and the exhaust through hole is provided inside the suction nozzle body. With this arrangement, when the atomized liquid in the liquid storage cup is consumed by the atomizer core and the liquid storage chamber needs to be replenished with atomized liquid, the entire suction nozzle assembly can be detached from the liquid storage cup to expose the liquid injection through hole. At this time, atomized liquid can be injected into the liquid storage chamber through the liquid injection through hole to replenish the atomized liquid; after the atomized liquid is replenished, the suction nozzle body is installed back on the top of the liquid storage cup, so that the sealing member seals the liquid injection through hole and the exhaust through hole to prevent the atomized liquid from leaking to the outside from the liquid injection through hole and the exhaust through hole, so that the atomizer can continue to be used. It can be seen that after the atomized liquid in the liquid storage chamber of the atomizer provided by the present application is consumed by the atomizer core, the atomized liquid can be replenished through the liquid injection hole, so that the atomizer can be reused. Compared with traditional disposable atomizers, the atomizer provided by the present application is not only beneficial to reducing the user's usage cost, but also beneficial to environmental protection.

[0025] 2. Since the seal is arranged inside the nozzle body and is not exposed from the inside of the nozzle body, it is difficult for the user's hands to touch the seal during the process of disassembling and assembling the nozzle body, thereby effectively preventing the user's hands from being contaminated by the atomized liquid adhering to the seal and affecting the user's experience.

[0026] 3. By arranging an exhaust through-hole at the top of the liquid storage cup and spaced apart from the liquid injection through-hole, the air in the storage chamber can be discharged to the outside through the exhaust through-hole during the process of injecting the atomized liquid into the storage chamber through the liquid injection through-hole. In this way, on the one hand, the smoothness of the liquid injection process can be improved; on the other hand, the risk of the air pressure in the storage chamber increasing due to the inability of the air in the storage chamber to be discharged to the outside can be effectively reduced during the liquid injection process, thereby causing the atomized liquid in the storage chamber to leak from the position where the storage chamber is connected to the atomizer core due to the compression of the air pressure.

[0027] 4. By setting the aperture of the injection hole to 2.5 mm to 8 mm, it is convenient for users to inject the atomized liquid into the storage cavity through a syringe or an injection bottle, thereby improving the convenience of injection.

[0028] 5. By setting the aperture of the exhaust through hole to 0.8 mm to 6 mm, it can be ensured that during the process of injecting atomized liquid into the storage chamber through the liquid injection through hole, the air in the storage chamber can be smoothly discharged to the outside.

[0053] Please refer to Figure 1-3 and Figure 7 An embodiment of the present application provides an atomizer, which includes a liquid storage cup 1, an atomizing core 2 and a nozzle assembly 3, wherein:

[0054] The interior of the liquid storage cup 1 is provided with an airway 101 and a storage cavity 102 for storing the atomized liquid. The top of the liquid storage cup 1 is provided with a liquid injection hole 111 and an exhaust hole 112 arranged at intervals. The liquid injection hole 111 and the exhaust hole 112 are both connected to the storage cavity 102, and the aperture of the liquid injection hole 111 is 2.5mm~8mm, and the aperture of the exhaust hole 112 is 0.8mm~6mm. Figure 7As shown, assuming that the hole diameter of the liquid injection through hole 111 is d1 and the hole diameter of the exhaust through hole 112 is d2, then 2.5mm≤d1≤8mm and 0.8mm≤d2≤6mm, for example, d1 can be 2.5mm, 3mm, 3.5mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc., and d2 can be 0.8mm, 1mm, 1.5mm, 2mm, 3mm, 4mm, 5mm, 6mm, etc. It should be noted here that in specific implementation, the cross-sectional shape of the liquid injection through hole 111 can be circular, oval, triangular, rectangular, trapezoidal, racetrack-shaped or other irregular shapes, which can be determined according to actual use needs, and the specific shape of the cross section of the liquid injection through hole 111 is not specifically limited in the present embodiment. Similarly, the cross-sectional shape of the exhaust through hole 112 can be circular, oval, triangular, rectangular, trapezoidal, racetrack-shaped or other irregular shapes, which can be determined according to actual use needs, and the specific shape of the cross section of the exhaust through hole 112 is also not specifically limited in the present embodiment. In addition, it should be noted here that in specific implementation, the liquid injection through hole 111 and the exhaust through hole 112 can be arranged on the top end face of the liquid storage cup 1, or on the top side wall of the liquid storage cup 1, which can be determined according to actual needs, and the present embodiment does not specifically limit this.

[0055] The atomizing core 2 is installed on the airflow flow path of the airway 101, so that the aerosol generated by the atomizing core 2 can be carried away by the suction airflow formed in the airway 101 and discharged to the mouthpiece body 31 for the user to smoke, and the atomizing core 2 is in communication with the storage cavity 102, so that the atomizing core 2 can suck the atomizing liquid from the storage for heating and atomization to generate the aerosol.

[0056] The nozzle assembly 3 includes a sealing member 32 and a nozzle body 31 having a suction channel 311. The sealing member 32 is fixed within the nozzle body 31. The nozzle body 31 is detachably connected to the top of the liquid storage cup 1. Furthermore, the suction channel 311 of the nozzle body 31 is connected to the airway 101 of the liquid storage cup 1. The sealing member 32 seals the liquid injection hole 111 and the exhaust hole 112. It should be noted that, in practice, the sealing member 32 can be made of silicone, rubber, silicone rubber, or other sealing materials, as long as they meet the requirements of use. This embodiment does not impose any specific restrictions on this. Furthermore, the detachable connection between the nozzle body 31 and the liquid storage cup 1 can be a threaded connection, a snap connection, a plug-in connection, a magnetic connection, or the like, as long as they meet the requirements of use. This embodiment does not impose any specific restrictions on this. When the detachable connection between the nozzle body 31 and the liquid storage cup 1 is a snap connection, the lower end of the nozzle body 31 is snapped onto the top of the liquid storage cup 1. In addition, it should be noted that, in a specific implementation, the specific method of the sealing member 32 to seal the liquid injection through hole 111 and the exhaust through hole 112 can be a blocking method or a covering method, as long as it can meet the use requirements. This embodiment does not impose any specific restrictions on this. It can be understood that when the sealing member 32 seals the liquid injection through hole 111 and the exhaust through hole 112 by blocking, the sealing member 32 usually has a plunger portion that can be inserted into the liquid injection through hole 111 and the exhaust through hole 112; and when the sealing member 32 seals the liquid injection through hole 111 and the exhaust through hole 112 by covering, the sealing member 32 covers the opening of the liquid injection through hole 111 and the opening of the exhaust through hole 112.

[0057] In this embodiment, based on the above structural design, the atomizer provided in this embodiment has the following technical effects:

[0058] 1. When the atomized liquid in the liquid storage cup 1 is consumed by the atomizer core 2 and the liquid storage chamber needs to be replenished with atomized liquid, the entire suction nozzle assembly 3 can be detached from the liquid storage cup 1 to expose the liquid injection through hole 111. At this time, the atomized liquid can be injected into the liquid storage chamber through the liquid injection through hole 111 (in some specific application scenarios, the bottle mouth of the liquid injection bottle containing the atomized liquid can be inserted into the liquid injection through hole 111, and then the atomized liquid in the liquid injection bottle can be injected into the liquid storage cup 1 by pouring the liquid injection bottle or squeezing the liquid injection bottle). After the atomized liquid is replenished, the nozzle body 31 is installed back on the top of the liquid storage cup 1, so that the sealing member 32 seals the liquid injection through hole 111 and the exhaust through hole 112 to prevent the atomized liquid from leaking to the outside from the liquid injection through hole 111 and the exhaust through hole 112. In this way, the atomizer can be reused. Compared with the traditional disposable atomizer, the atomizer provided in this embodiment is not only beneficial to reducing the user's usage cost, but also beneficial to environmental protection.

[0059] 2. Since the seal 32 is disposed inside the nozzle body 31 and is not exposed from the inside of the nozzle body 31, it is difficult for the user's hands to touch the seal 32 during the process of disassembling and assembling the nozzle body 31, thereby effectively preventing the user's hands from being contaminated by the atomized liquid adhering to the seal 32 and affecting the user's experience.

[0060] 3. By providing an exhaust through-hole 112 at the top of the liquid storage cup 1, which is spaced apart from the liquid injection through-hole 111, the air in the storage chamber 102 can be discharged to the outside through the exhaust through-hole 112 during the process of injecting the atomized liquid into the storage chamber 102 through the liquid injection through-hole 111. In this way, on the one hand, the smoothness of the liquid injection process can be improved, and on the other hand, the risk of the air pressure in the storage chamber 102 increasing due to the inability of the air in the storage chamber 102 to be discharged to the outside can be effectively reduced during the liquid injection process, thereby causing the atomized liquid in the storage chamber 102 to leak from the position where the storage chamber 102 is connected to the atomizer core 2 due to the compression of the air pressure.

[0061] 4. By setting the aperture of the liquid injection hole 111 to 2.5 mm to 8 mm, it is convenient for the user to inject the atomized liquid into the storage cavity 102 through a syringe or a liquid injection bottle, thereby improving the convenience of liquid injection.

[0062] 5. By setting the aperture of the exhaust through hole 112 to 0.8 mm to 6 mm, it can be ensured that during the process of injecting atomized liquid into the storage cavity 102 through the liquid injection through hole 111, the air in the storage cavity 102 can be smoothly discharged to the outside.

[0063] Further, referring to the figures, in some optional embodiments of the present application, the aperture d1 of the liquid injection hole 111 is 3.5mm~6mm, the aperture d2 of the exhaust hole 112 is 1mm~4mm, and the aperture d1 of the liquid injection hole 111 is larger than the aperture d2 of the exhaust hole 112.

[0064] In this embodiment, on the one hand, by further setting the aperture d1 of the injection hole 111 to 3.5mm~6mm, not only can the injection hole 111 be adapted to the vast majority of injection tools currently on the market, but it can also ensure that the atomized liquid can smoothly pass through the injection hole 111 and enter the storage chamber 102; on the other hand, by further setting the aperture d2 of the exhaust hole 112 to 1mm~4mm, and setting the aperture d1 of the injection hole 111 to be larger than the aperture d2 of the exhaust hole 112, such a setting can enable the air in the storage chamber 102 to be discharged to the outside more smoothly and stably during the injection process, thereby enabling the liquid level of the atomized liquid in the storage chamber 102 to rise at a more appropriate speed during the injection process, thereby avoiding the injection speed being too slow and increasing the user's waiting time, and at the same time avoiding the injection speed being too fast and increasing the risk of the atomized liquid overflowing from the injection hole 111 or the exhaust hole 112 due to the user's lack of concentration.

[0065] For further information, please refer to Figure 3 and Figure 7 In some optional embodiments of the present application, the minimum horizontal distance between the inner wall of the opening of the liquid injection hole 111 and the inner wall of the opening of the exhaust hole 112 is 7 mm to 15 mm. Figure 7 As shown, assuming the minimum horizontal distance between the inner wall of the opening of the liquid injection through hole 111 and the inner wall of the opening of the exhaust through hole 112 is L, then 7mm≤L≤15mm. This arrangement ensures that there is sufficient distance between the opening of the liquid injection through hole 111 and the opening of the exhaust through hole 112, thereby reducing the risk of the opening of the exhaust through hole 112 being blocked by the user's hand during the liquid injection process, thereby affecting the smoothness of exhaust.

[0066] For further information, please refer to Figure 2-6 In some optional embodiments of the present application, the liquid injection through hole 111 and the exhaust through hole 112 are both provided on the top surface of the liquid storage cup 1, and the surface of the sealing member 32 facing the liquid storage cup 1 is provided with a first annular sealing portion 321 and a second annular sealing portion 322 that are spaced apart. The first annular sealing portion 321 abuts against the top surface of the liquid storage cup 1 and surrounds the opening of the liquid injection through hole 111, and the second annular sealing portion 322 abuts against the top surface of the liquid storage cup 1 and surrounds the opening of the exhaust through hole 112, and the vertical height of the first annular sealing portion 321 protruding from the sealing member 32 is 0.2 mm to 1 mm, and the vertical height of the second annular sealing portion 322 protruding from the sealing member 32 is 0.2 mm to 1 mm. Figure 7 As shown, assuming that the vertical height of the first annular sealing portion 321 protruding from the sealing member 32 is h1, and the vertical height of the second annular sealing portion 322 protruding from the sealing member 32 is h2, then 0.2 mm ≤ h1 ≤ 1 mm, 0.2 mm ≤ h2 ≤ 1 mm.

[0067] In this embodiment, based on the above structural design, a first annular sealing portion 321 and a second annular sealing portion 322 with vertical heights of 0.2mm to 1mm are protruded on the surface of the side of the sealing member 32 facing the liquid storage cup 1. When the suction nozzle body 31 is installed on the top of the liquid storage cup 1, the first annular sealing portion 321 can maintain close contact with the top surface of the liquid storage cup 1 and surround the orifice of the liquid injection through hole 111. At the same time, the second annular sealing portion 322 can maintain close contact with the top surface of the liquid storage cup 1 and surround the orifice of the exhaust through hole 112. In this way, on the one hand, it is less likely to produce an installation gap between the sealing member 32 and the top surface of the liquid storage cup 1, thereby improving the sealing effect between the sealing member 32 and the top surface of the liquid storage cup 1, making it more difficult for the atomized liquid to leak to the outside from the liquid injection through hole 111 and the exhaust through hole 112. On the other hand, the present embodiment achieves sealing of the liquid injection through hole 111 and the exhaust through hole 112 by covering the openings in this way. Compared with achieving sealing of the liquid injection through hole 111 and the exhaust through hole 112 by blocking, since the sealing member 32 will not be inserted into the liquid injection through hole 111 and the exhaust through hole 112, when the atomized liquid is replenished and the suction nozzle body 31 is installed back on the top of the liquid storage cup 1, it is difficult for the sealing member 32 to press the air in the liquid injection through hole 111 and the exhaust through hole 112 into the storage chamber 102, thereby effectively reducing the increase in the air pressure in the liquid storage chamber caused by the air in the liquid injection through hole 111 and the exhaust through hole 112 being pressed into the storage chamber 102 by the sealing member 32, thereby causing the atomized liquid in the storage chamber 102 to be squeezed by the air pressure and discharged from the position where the storage chamber 102 is connected to the atomizer core 2 (i.e. Figure 3 There is a risk of leakage at the liquid outlet hole 131 in the liquid outlet hole.

[0068] For further information, please refer to Figure 3-6In some optional embodiments of the present application, the first annular sealing portion 321 is symmetrically arranged with the second annular sealing portion 322 with the central axis of the suction channel 311 as the axis of symmetry, that is, the shape and size of the first annular sealing portion 321 are the same as the shape and size of the first annular sealing portion 321, and the cross-sectional area of ​​the orifice of the injection hole 111 is larger than the cross-sectional area of ​​the orifice of the exhaust through hole 112, that is, the sizes of the first annular sealing portion 321 and the second annular sealing portion 322 are sufficient to surround any one of the orifices of the injection through hole 111 and the exhaust through hole 112. With such a configuration, during the process of installing the suction nozzle body 31 on the top of the liquid storage cup 1, the user does not need to confirm whether the first annular sealing portion 321 corresponds to the liquid injection hole 111 and whether the second annular sealing portion 322 corresponds to the exhaust hole 112. It can also ensure that after the suction nozzle body 31 is installed on the top of the liquid storage cup 1, the openings of the liquid injection hole 111 and the exhaust hole 112 can be surrounded by the corresponding annular sealing portions to achieve sealing, which is conducive to improving the installation convenience of the suction nozzle body 31.

[0069] For further information, please refer to Figure 2-6 In some optional embodiments of the present application, the airway 101 has an air outlet 1130 located on the top surface of the liquid storage cup 1, and a third annular sealing portion 323 is protruded from the surface of the sealing member 32 facing the liquid storage cup 1. The vertical height h3 of the third annular sealing portion 323 protruding from the sealing member 32 is 0.2 mm to 1 mm. The third annular sealing portion 323 is located between the first annular sealing portion 321 and the second annular sealing portion 322. The third annular sealing portion 323 is hollow and through to form an air vent 3230. The third annular sealing portion 323 abuts against the top surface of the liquid storage cup 1 and surrounds the air outlet 1130, and the air outlet 1130 is connected to the air inlet port of the suction channel 311 through the air vent 3230. Such a configuration enables sealed communication between the air outlet 1130 of the airway 101 and the air inlet port of the suction channel 311, thereby preventing the air in the suction nozzle body 31 from being sucked into the suction channel 311 and mixing with the aerosol in the suction channel 311 to reduce the concentration of the aerosol when the user bites the suction nozzle body 31 for suction. This can prevent the aerosol concentration from being reduced and affecting the user's smoking taste.

[0070] For further information, please refer to Figure 4-6In some optional embodiments of the present application, a first connecting rib 324 and a second connecting rib 325 are convexly provided on the side surface of the sealing member 32 facing the liquid storage cup 1, and the first connecting rib 324 is located between the first annular sealing portion 321 and the third annular sealing portion 323, and the second connecting rib 325 is located between the second annular sealing portion 322 and the third annular sealing portion 323. One end of the first connecting rib 324 is connected to the first annular sealing portion 321 as a whole, and the other end is connected to the third annular sealing portion 323 as a whole. One end of the second connecting rib 325 is connected to the second annular sealing portion 322 as a whole, and the other end is connected to the third annular sealing portion 323 as a whole.

[0071] In this embodiment, the provision of the first connecting rib 324 and the second connecting rib 325 can enhance the structural stability of the first annular sealing portion 321, the second annular sealing portion 322 and the third annular sealing portion 323, thereby improving the sealing reliability between the first annular sealing portion 321 and the top surface of the liquid storage cup 1, between the second annular sealing portion 322 and the top surface of the liquid storage cup 1, and between the third annular sealing portion 323 and the top surface of the liquid storage cup 1.

[0072] Further, please refer to Figure 2-3 and Figure 7 In some optional embodiments of the present application, a mounting hole 115 coaxially arranged with the liquid injection through hole 111 is further provided in the top of the liquid storage cup 1, the mounting hole 115 is located below the liquid injection through hole 111 and is connected to the storage chamber 102, and the aperture of the mounting hole 115 is larger than the aperture of the liquid injection through hole 111; the atomizer also includes a sealing body 4 fixed in the mounting hole 115, the sealing body 4 has a sheet portion 41 corresponding to the liquid injection through hole 111, the sheet portion 41 is made of a flexible material (such as silicone, rubber, silicone rubber and other flexible materials) and the thickness of the sheet portion 41 is 0.3mm~2mm, and a slit 410 is provided on the sheet portion 41 that passes through itself, the gap size of the slit 410 is 0.01mm~0.18mm, the length of the slit 410 is 2.5mm~5mm, and the length of the slit 410 is less than or equal to the aperture of the liquid injection through hole 111.

[0073] In this embodiment, based on the above structural design, in some specific application scenarios, when the user injects the atomized liquid into the storage chamber 102 by means of a liquid injection bottle, the bottle mouth of the liquid injection bottle can be inserted into the slit 410 of the sheet portion 41 through the liquid injection through hole 111. Since the sheet portion 41 is made of a flexible material, the slit 410 of the sheet portion 41 will be expanded by the bottle mouth of the liquid injection bottle and the bottle mouth of the liquid injection bottle can pass through the sheet portion 41 to inject liquid. After the liquid injection is completed, the bottle mouth of the liquid injection bottle is pulled out from the slit 410 of the sheet portion 41. The slit 410 of the sheet portion 41 is opened. It will return to its original state. Since the slit 410 of the sheet portion 41 has a gap size of 0.01mm to 0.18mm in its natural state, the air trapped in the slit 410 can form an air blockage. The existence of this air blockage prevents the atomized liquid in the storage chamber 102 from passing through the slit 410 and leaking to the outside. That is, by adding the sheet portion 41 with the slit 410, the convenience of liquid injection can be ensured while making it more difficult for the atomized liquid in the storage chamber 102 to leak to the outside through the liquid injection hole 111 after the nozzle body 31 is installed back on the top of the liquid storage cup 1. In particular, by setting the length of the slit 410 to 2.5mm to 5mm, it is easier for the bottle mouth of the liquid injection bottle to open the slit 410, so that the bottle mouth of the liquid injection bottle can smoothly pass through the sheet portion 41 to inject liquid. By setting the thickness of the sheet portion 41 to 0.3 mm to 2 mm, it can ensure that the bottle mouth of the liquid filling bottle can smoothly pass through the sheet portion 41 for liquid filling, while at the same time, the sheet portion 41 can have good structural toughness to reduce the risk of the sheet portion 41 being damaged by the bottle mouth of the liquid filling bottle during the liquid filling process.

[0074] In this embodiment, it should be noted that, in specific implementation, the number of slits 410 can be one or more, which can be determined according to actual use needs, and this embodiment does not impose any specific restrictions on this. Among them, when the number of slits 410 is multiple, the multiple slits 410 can be arranged crosswise so that during the liquid injection process, the bottle mouth of the liquid injection bottle can more easily pass through the sheet portion 41 for injection. For example, Figure 7 As shown, there are two slits 410, and the two slits 410 are arranged crosswise.

[0075] For further information, please refer to Figure 3 In some optional embodiments of the present application, in order to improve the installation stability of the sealing body 4, the atomizer also includes a hollow through-ring 5, the clamping ring 5 is interference fit in the mounting hole 115, and the sealing body 4 is clamped between the upper end of the clamping ring 5 and the top wall of the mounting hole 115.

[0076] Furthermore, in some optional embodiments of the present application, the specific structural composition of the atomizer may be as follows:

[0077] Please refer to Figure 3 and Figure 8 The liquid storage cup 1 comprises a shell 11, a base 12, and a connecting pipe 13 with an atomization channel 130. The top end surface of the shell 11 is provided with a liquid injection through hole 111 and an exhaust through hole 112. The lower end of the suction nozzle body 31 is buckled to the top of the shell 11. The base 12 is fixedly fitted to the bottom end of the shell 11. The top of the shell 11 is provided with a first mounting channel between the liquid injection through hole 111 and the exhaust through hole 112. The base 12 is provided with a second mounting through hole 1220. One end of the connecting pipe 13 is sealingly fitted into the first mounting channel, and the other end is sealingly fitted into the second mounting through hole 1220. The shell 11, the base 12, and the connecting pipe 13 collectively enclose a storage cavity 102. The second mounting through hole 1220, the atomization channel 130, and the first mounting through hole 113 are sequentially communicated to form at least part of an air passage 101. The side wall of the connecting pipe 13 is provided with a liquid outlet hole 131 in communication with the storage cavity 102. The atomization core 2 is installed in the connecting pipe 13 and covers the liquid outlet hole 131.

[0078] In the present embodiment, based on the above structural design, the atomizer provided in the present embodiment has the advantage of convenient assembly. Specifically, in some application scenarios of manufacturing an atomizer, the atomization core 2 can be first installed in the connecting pipe 13, then the lower end of the connecting pipe 13 is inserted into the second mounting through hole 1220 of the base 12, then the upper end of the connecting pipe 13 is inserted into the second mounting through hole 1220 of the shell 11 and the base 12 is fitted with the bottom end of the shell 11, and finally the lower end of the suction nozzle body 31 is buckled to the top of the shell 11. In this way, a complete atomizer can be obtained, which is relatively convenient to assemble.

[0079] Further, in some optional embodiments of the present application, the specific structural composition of the atomization core 2 can be as follows:

[0080] Please refer to Figure 3 The atomization core 2 comprises a heating body 21, a liquid control body 24, a liquid guide body 22 made of porous material (such as fiber cotton, sponge, etc.), and a support sleeve 23 inserted into the connecting pipe 13. The side wall of the support sleeve 23 is provided with a liquid inlet hole 230 opposite the liquid outlet hole 131. The liquid guide body 22 and the liquid control body 24 are both hollow and through. The heating body 21 is connected to the inner wall of the liquid guide body 22. The liquid guide body 22 is installed in the support sleeve 23 and covers the liquid inlet hole 230. The liquid control body 24 is sleeved on the outer wall of the support sleeve 23 and covers the liquid inlet hole 230 and the liquid outlet hole 131. The liquid control body 24 is made of glass fiber or porous material (such as fiber cotton, sponge, etc.), and the wall thickness of the liquid control body 24 is 0.1mm-0.6mm. The structure of the heating body 21 can be a metal heating sheet, a metal heating mesh, a metal heating wire, etc.

[0081] In this embodiment, based on the above-mentioned structural design, the atomized liquid in the storage cavity 102 can flow into the liquid-guiding liquid 22 through the liquid outlet hole 131, the control liquid 24, and the liquid inlet hole 230 in sequence. When the heating element 21 is energized and heated, the heating element 21 atomizes the atomized liquid adsorbed on the inner wall of the liquid-guiding liquid 22 into an aerosol. When the user bites the nozzle body 31 to inhale, a suction airflow is formed on the airflow flow path connecting the airway 101 and the suction channel 311. The suction airflow takes away the aerosol when flowing through the heating element 21. The aerosol is finally discharged to the nozzle body 31 along with the suction airflow and is inhaled by the user. Among them, compared with the traditional atomizer core structure that only includes the bracket sleeve 23, the guide liquid 22 and the heating element 21, in the atomizer core 2 provided in this embodiment, by adding a control liquid 24 with a wall thickness of 0.1mm to 0.6mm between the liquid outlet hole 131 and the liquid inlet hole 230, the control liquid 24 can reduce the fluidity of the atomized liquid, so that the atomized liquid in the storage cavity 102 can flow into the guide liquid 22 at a more appropriate flow rate. In this way, on the one hand, when the atomizer is in a static state, the atomized liquid can be reduced from seeping from the inner wall of the guide liquid 22 due to the atomized liquid flowing into the guide liquid 22 too fast. On the other hand, it can effectively reduce the risk of "liquid flying" in the atomizer core 2 due to the excessively fast flow of the atomized liquid into the guide liquid 22 during the user's puffing process (it should be noted here that the so-called liquid flying phenomenon refers to the phenomenon that during the user's puffing process, the part of the atomized liquid on the guide liquid 22 that has not yet been atomized by the heating element 21 in time will be sucked into the user's mouth due to the problem of excessively fast liquid supply speed of the guide liquid 22). This can effectively reduce the risk of the user inhaling the atomized liquid that has not been atomized in time by the heating element 21, thereby effectively improving the user's puffing experience.

[0082] Furthermore, in some optional embodiments of the present application, the nozzle body 31 and the housing 11 can be snap-fitted together in the following manner, specifically:

[0083] Please refer to Figure 3 、 Figure 6 and Figure 7, at least one of the suction nozzle body 31 and the shell 11 is made of plastic, the top side wall of the shell 11 is provided with two first buckling portions 114 which are arranged opposite to each other, the inner wall of the lower end of the suction nozzle body 31 is provided with two second buckling portions 312 which are arranged opposite to each other, each first buckling portion 114 and each second buckling portion 312 are arranged one-to-one, each first buckling portion 114 has a first guide surface 1141 and a second guide surface 1142 which is arranged above the first guide surface 1141 along the height direction of the shell 11, each second buckling portion 312 has a third guide surface 3121 and a fourth guide surface 3122 which is arranged above the third guide surface 3121, the included angle between each first guide surface 1141 and the side wall surface of the shell 11 is obtuse, the included angle between each third guide surface 3121 and the inner wall surface of the suction nozzle body 31 is obtuse, and the first guide surface 1141 and the fourth guide surface 3122 are in contact in the corresponding first buckling portion and second buckling portion.

[0084] In the embodiment, based on the above structural design, under the mutual abutting action between the two first buckling portions and the two second buckling portions, the suction nozzle body 31 can be stably buckled on the top of the shell 11 and is not easy to be separated. In the process of buckling the lower end of the suction nozzle body 31 on the top of the shell 11, when the third guide surface 3121 of the second buckling portion 312 extrudes the second guide surface 1142 of the first buckling portion 114 with a certain force, since the included angle between the second guide surface 1142 of the first buckling portion and the side wall surface of the shell 11 is obtuse, and the included angle between the third guide surface 3121 of the second buckling portion and the inner wall surface of the suction nozzle body 31 is also obtuse, the relative sliding between the second guide surface 1142 and the third guide surface 3121 can be more easily occurred, so that the second buckling portion 312 can be more easily moved below the first buckling portion 114 and form mutual abutment with the first buckling portion 114, that is, it is beneficial for the user to buckle the suction nozzle body 31 on the top of the shell 11 more labor-saving. Similarly, in the process of detaching the suction nozzle body 31 from the top of the shell 11, when the fourth guide surface 3122 of the second buckling portion 312 extrudes the first guide surface 1141 of the first buckling portion 114 with a certain force, since the included angle between the first guide surface 1141 of the first buckling portion and the side wall surface of the shell 11 is obtuse, and the included angle between the fourth guide surface 3122 of the second buckling portion and the inner wall surface of the suction nozzle body 31 is also obtuse, the relative sliding between the first guide surface 1141 and the fourth guide surface 3122 can be more easily occurred, so that the second buckling portion 312 can be more easily moved above the first buckling portion 114 and get rid of the limiting action of the first buckling portion 114, that is, it is beneficial for the user to detach the suction nozzle body 31 from the top of the shell 11 more labor-saving.

[0085] For further information, please refer to Figure 1 、 Figure 3 and Figure 9 In some optional embodiments of the present application, the base 12 includes a first base body 121 and a second base body 122 provided with a second mounting through hole 1220.

The first base body 121 is fixedly fitted in the bottom end of the housing 11 and is located below the second base body 122. A ventilation gap 140 connected to the second mounting through hole 1220 is formed between the first base body 121 and the second base body 122. The bottom end surface of the first base body 121 is provided with a ventilation gap 140 connected to the second mounting through hole 1220. 140 is connected to the air inlet 1210; the atomizer also includes a liquid absorbent cotton 60, a first magnetic member 61 and a first electrode assembly 62 electrically connected to the atomizing core 2, the liquid absorbent cotton 60 is arranged on the side of the first base body 121 facing the second base body 122 and is arranged corresponding to the second mounting through hole 1220, the first magnetic member 61 is fixed in the first base body 121 and is exposed on the bottom end surface of the first base body 121, and the first electrode assembly 62 is fixed in the first base body 121 and is exposed on the bottom end surface of the first base body 121.

[0086] In this embodiment, the provision of the air inlet 1210 facilitates the flow of external air into the air passage 101 of the liquid storage cup 1 and forms a suction airflow when the user bites the nozzle for suction.

[0087] In this embodiment, when liquid leakage occurs at the atomizer core 2 , the absorbent cotton 60 can absorb the atomized liquid leaking from the atomizer core 2 , thereby preventing the atomized liquid from leaking to the outside through the air inlet 1210 .

[0088] In this embodiment, the provision of the first magnetic member 61 can facilitate the stable assembly of the atomizer and the power supply assembly 7 of the electronic atomization device in some usage scenarios where the atomizer is applied to the electronic atomization device.

[0089] In this embodiment, the provision of the first electrode assembly 62 can facilitate the electrical connection between the atomizer core 2 and the power supply assembly 7 of the electronic atomization device in some usage scenarios where the atomizer is applied to the electronic atomization device.

[0090] Correspondingly, please refer to Figure 9 The embodiment of the present application also provides an electronic atomization device, which includes a power supply component 7 and an atomizer in any of the above embodiments (such as Figure 1-8 As shown), wherein the power supply assembly 7 is electrically connected to the atomizer core 2.
