Description

Technical Field

[0001] This application relates to the field of atomization equipment technology, specifically to an atomization device and an atomization equipment. Background Technology

[0002] Currently, common atomizing devices with external liquid reservoirs typically employ two connection methods between the external and internal liquid reservoirs: one method involves at least two connecting holes, one for liquid replenishment and the other for ventilation. However, these connecting holes require relatively large spaces, making them unsuitable for small-volume atomizing devices. Furthermore, the normally open ventilation path used for ventilation is prone to leakage during temperature or orientation changes. The other method involves only one connecting hole, through which the external liquid reservoir directly supplies liquid to the internal reservoir. However, this method is susceptible to gas lock or air bubble retention, leading to difficulties in liquid replenishment and inconsistent liquid supply. Due to these shortcomings, atomizing devices struggle to simultaneously address both liquid replenishment and ventilation, resulting in inconvenience and a negative impact on the user experience. Summary of the Invention

[0003] In order to solve the problems of relatively large interconnecting space of atomizing devices in related technologies, which are not conducive to application in small-volume equipment, are prone to leakage, and cause difficulties in replenishing liquid and intermittent liquid supply due to poor ventilation, this application provides an atomizing device and an atomizing equipment.

The device is used to adsorb and heat the aerosol matrix, and to allow the generated aerosol to flow out through the outlet pipe. When the microporous structure is sealed by the aerosol matrix in the outer cavity, the aerosol matrix in the outer cavity can pass through the microporous structure into the inner cavity under suction negative pressure, and allow the gas in the inner cavity to pass through the microporous structure into the outer cavity. When the microporous structure is not sealed by the aerosol matrix in the outer cavity, the aerosol matrix in the first liquid storage chamber can pass through the liquid replenishment interface into the outer cavity under suction negative pressure, and allow the gas in the outer cavity to pass through the liquid replenishment interface into the first liquid storage chamber.

[0005] In a further embodiment of this application, the microporous structure is located at the bottom of the partition wall; and / or, the flow area of ​​the microporous structure is in the range of 0.2 mm² to 0.3 mm².

[0006] In a further embodiment of this application, a buffer space is formed between the liquid surface of the aerosol matrix in the outer cavity and the inner top wall of the outer cavity.

[0007] In a further embodiment of this application, at least a portion of the partition wall is an arc-shaped structure extending circumferentially, and at least a portion of the inner cavity is located inside the outer cavity.

[0008] In a further embodiment of this application, a plurality of microporous structures are arranged at intervals along the circumference of the inner cavity; and when the microporous structures are closed by the aerosol matrix of the outer cavity, at least one microporous structure can introduce the aerosol matrix in the outer cavity into the inner cavity under the action of suction negative pressure, and at least one microporous structure can introduce the gas in the inner cavity into the outer cavity under the action of suction negative pressure.

[0009] In a further embodiment of this application, the top of the second liquid storage chamber has a first connecting pipe that communicates with the air outlet pipe, and the second liquid storage chamber has an air guiding chamber that communicates with the outside; the atomizing core assembly includes: an atomizing core, which is correspondingly disposed with the first connecting pipe, the top of the atomizing core communicating with the first connecting pipe, and the bottom of the atomizing core communicating with the air guiding chamber; and a first liquid suction element, which is sleeved on the outside of the atomizing core and is used to adsorb the aerosol matrix and conduct the aerosol matrix to the atomizing core.

[0010] In a further embodiment of this application, a portion of the outer sidewall of the first liquid-absorbing element abuts against the partition wall, and the area of ​​the first liquid-absorbing element corresponding to the microporous structure has a concave venting groove, which connects the corresponding microporous structure and the first connecting tube.

[0011] In a further embodiment of this application, the second liquid storage chamber includes: a second housing, the bottom of which is through, a first connecting pipe and a liquid replenishment interface located at the top of the second housing, and the top of the partition wall connected to the inner top wall of the second housing; a second base, which is detachably connected to the bottom of the second housing, and an air guiding cavity is formed inside the second base, and the second base has an air guiding hole communicating with the air guiding cavity; and a second sealing member, which is connected to the top of the second base, the top of the second sealing member abutting against the bottom of the partition wall and forming an inner cavity and an outer cavity, and the bottom of the atomizing core penetrating the second sealing member and communicating with the air guiding cavity.

[0012] In a further embodiment of this application, the area corresponding to the outer wall of the second liquid storage tank and the outer cavity is a transparent structure.

[0013] In a further embodiment of this application, the first liquid storage tank and the second liquid storage tank are detachably connected; the bottom of the first liquid storage tank has a liquid replenishment hole, and the liquid replenishment interface is detachably connected to the liquid replenishment hole.

[0014] An embodiment of the second aspect of this application provides an atomizing device, including: the atomizing apparatus of any of the embodiments of the first aspect described above; and a power supply device, wherein the power supply device is electrically connected to the atomizing core assembly of the atomizing apparatus.

[0015] The beneficial effects of the above-mentioned technical solution of this application are as follows: According to the technical solution in this application, through structural improvements and optimizations, a single-hole connection is adopted between the first and second liquid storage chambers. Simultaneously, an inner and outer cavity are connected within the second liquid storage chamber via a microporous structure. The outer cavity serves as a buffer space. Under pressure equilibrium, the liquid replenishment interface and microporous structure can be sealed by an aerosol matrix. Liquid replenishment and ventilation, as well as liquid intake from the outer cavity to the inner cavity, are only performed during suction using negative pressure. This quantitative liquid replenishment effectively prevents difficulties in liquid replenishment and discontinuous liquid supply that can occur with single-hole connection structures. It also prevents leakage from the inner cavity due to excessive pressure, thus effectively suppressing problems such as excessive liquid supply leading to gushing leakage and insufficient liquid supply causing dry burning. This improves the user experience, and the overall structure is relatively compact, making it suitable for use in small-volume devices. Attached Figure Description

[0034] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the objects being described and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0035] The following describes some embodiments of the atomizing device and atomizing equipment provided in this application with reference to the accompanying drawings.

[0036] An embodiment of the first aspect of this application provides an atomizing device 100, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the atomizing device 100 includes a first liquid storage chamber 1, a second liquid storage chamber 2, and an atomizing core assembly 3. The first liquid storage chamber 1 and the second liquid storage chamber 2 are arranged along the height direction, with the first liquid storage chamber 1 positioned above the second liquid storage chamber 2. The first liquid storage chamber 1 has a cavity capable of containing an aerosol matrix and an exhaust pipe 111 extending along the height direction. A suction nozzle 112 is formed at the top of the first liquid storage chamber 1 to facilitate suction. The second liquid storage chamber 2 has a mutually separated inner cavity 213 and an outer cavity 212. The partition wall 211 between the inner cavity 213 and the outer cavity 212 has multiple microporous structures 2111. The atomizing core assembly 3 is disposed in the inner cavity 213. A liquid replenishment interface 214 connecting the outer cavity 212 and the first liquid storage chamber 1 is provided at the top of the second liquid storage chamber 2. The atomizing core assembly 3 is connected to the air outlet pipe 111 and can adsorb the aerosol matrix and heat the aerosol matrix so that the aerosol matrix is ​​heated and atomized to generate aerosol. The generated aerosol can flow out from the air outlet pipe 111 with the airflow.

[0037] When the outer cavity 212 contains an aerosol matrix, such as Figure 5 In the example, the liquid level of the aerosol matrix is ​​higher than that of the microporous structure 2111, which seals the microporous structure 2111. The pressure inside and outside the microporous structure 2111 remains balanced, preventing the aerosol matrix in the outer cavity 212 from directly passing through the microporous structure 2111. Simultaneously, the pressure at both ends of the replenishment port 214 also remains balanced, preventing the aerosol matrix in the first storage chamber 1 from directly passing through the replenishment port 214 and entering the outer cavity 212 of the second storage chamber 2. When suction is performed, a negative pressure is created in the second storage chamber 2. Under this negative pressure, some of the aerosol matrix in the outer cavity 212 passes through the microporous structure 2111, while simultaneously causing some gas in the inner cavity 213 to exit through the micropores and enter the outer cavity 212.

[0038] When the aerosol matrix in the outer cavity 212 is depleted or the mass of the aerosol matrix in the outer cavity 212 is insufficient to seal the microporous structure 2111, such as Figure 4 In the example shown, the two sides of the microporous structure 2111 are connected. When a suction action is performed, a negative pressure is created in the outer cavity 212. Under the action of negative pressure, the aerosol matrix in the first liquid storage chamber 1 passes through the liquid replenishment port 214 and enters the outer cavity 212 to realize the liquid replenishment operation of the outer cavity 212. At the same time, some of the gas in the outer cavity 212 can pass through the liquid replenishment port 214 and enter the first liquid storage chamber 1, so as to achieve pressure balance in the first liquid storage chamber 1 through gas-liquid exchange. When the liquid level of the aerosol matrix in the outer cavity 212 is higher than that of the microporous structure 2111, the microporous structure 2111 is sealed again by the aerosol matrix.

[0039] It should be noted that the microporous structure 2111 in this embodiment has a small diameter pore that can be sealed by the aerosol matrix under natural conditions and can only be open under the action of suction negative pressure. There are multiple microporous structures 2111, i.e., at least two. When the microporous structures 2111 are sealed, the suction action creates negative pressure in the inner cavity 213. A portion of the multiple microporous structures 2111 is used for liquid inlet, and another portion is used for exhaust, thus creating gas-liquid displacement between the inner cavity 213 and the outer cavity 212. Furthermore, the atomizing device 100 can be used in conjunction with a power supply device to form a complete atomizing device. The atomizing core assembly 3 can be connected to the outside, allowing external air to enter the atomizing core assembly 3 and mix with the aerosol generated by the atomizing core assembly 3 to form an aerosol gas.

[0040] It is understandable that traditional atomizing devices 100 with external liquid replenishment chambers, if using a single-hole liquid inlet, are prone to venting difficulties, leading to intermittent liquid supply and affecting atomization performance. Therefore, most existing products use at least two connecting holes, one for liquid replenishment and the other for venting. However, the structure of the liquid replenishment hole 121 and the venting hole occupies a large space and is more complex, which is not conducive to application in small-volume atomizing devices 100. Moreover, the venting hole is also prone to leakage.

[0041] The atomizing device 100 in this embodiment, through structural improvements and optimizations, adopts a single-hole connection between the first liquid storage chamber 1 and the second liquid storage chamber 2. Simultaneously, an inner cavity 213 and an outer cavity 212 are connected in the second liquid storage chamber 2 via a microporous structure 2111. The outer cavity 212 serves as a transition space. Under pressure equilibrium, the liquid replenishment port 214 and the microporous structure 2111 can be sealed by the aerosol matrix. Liquid replenishment and ventilation are only performed during suction using negative pressure, and liquid is introduced from the outer cavity 212 into the inner cavity 213. Each replenishment is quantitative, effectively preventing difficulties in liquid replenishment and discontinuous liquid supply that can occur with the single-hole connection structure. It also prevents leakage from the inner cavity 213 due to excessive pressure, effectively suppressing problems such as excessive liquid supply leading to gushing leakage and insufficient liquid supply causing dry burning. This improves the user experience, and the overall structure is relatively compact, making it suitable for use in small-volume devices.

[0042] In further embodiments of this application, such as Figure 4As shown, in the height direction, the microporous structure 2111 is located at the bottom of the dividing wall, that is, at the bottom of the outer cavity 212 and the inner cavity 213. The aerosol matrix contained in the outer cavity 212 can pass through the microporous structure 2111 into the inner cavity 213 under negative pressure. Only after the aerosol matrix in the outer cavity 212 is basically exhausted will the liquid level be lower than the microporous structure 2111, exposing it. This ensures that the aerosol matrix in the outer cavity 212 is fully utilized, and there is virtually no residue at the bottom. It can be understood that if the microporous structure 2111 is located on the dividing wall far from the bottom, when the liquid level of the aerosol matrix in the outer cavity 212 is lower than the microporous structure 2111, the aerosol matrix will have difficulty passing through the microporous structure 2111 into the inner cavity 213, resulting in the ineffective utilization of the residual aerosol matrix at the bottom. The position of the microporous structure 2111 in this embodiment effectively prevents the above-mentioned problems.

[0043] Furthermore, such as Figure 4 In the example, the flow area of ​​the microporous structure 2111 is in the range of 0.2 mm² to 0.3 mm², so that the pore size of the microporous structure 2111 is kept within a small size range. Only under the action of suction negative pressure can the aerosol matrix in the outer cavity 212 pass through the microporous structure 2111 and enter the inner cavity 213. Under natural conditions, the viscous force of the aerosol matrix in the outer cavity 212 can keep the microporous structure 2111 closed, and the aerosol matrix will not pass through the microporous structure 2111.

[0044] In further embodiments of this application, such as Figure 5 In the example shown, when the outer cavity 212 contains an aerosol matrix, there is a certain gap between the liquid surface of the aerosol matrix in the outer cavity 212 and the inner top wall of the outer cavity 212 in the height direction. That is, the aerosol matrix contained in the outer cavity 212 does not completely fill the outer cavity 212, so that the gap area forms a buffer space 2121. When the environment changes (such as temperature shift, device posture change, etc.) and a pressure difference is generated between the first liquid storage tank 1 and the outer cavity 212, gas-liquid displacement can be formed between the buffer space 2121 and the first liquid storage tank 1 to eliminate the pressure difference, thereby avoiding the formation of a continuous leakage path.

[0045] For example, such as Figure 4 and Figure 5In the example above, if the outer cavity 212 is not within the buffer space 2121, and environmental changes cause the pressure in the first liquid storage chamber 1 to exceed the pressure in the outer cavity 212, the aerosol matrix in the first liquid storage chamber 1 will enter the outer cavity 212. This will create a pressure difference between the outer cavity 212 and the inner cavity 213, causing the aerosol matrix in the outer cavity 212 to pass through the microporous structure 2111 and enter the inner cavity 213. This results in an excess of aerosol matrix at the atomizing core assembly 3, leading to leakage. Therefore, by providing a buffer space 2121 at the top of the outer cavity 212, the aforementioned pressure difference can be buffered, effectively preventing leakage.

[0046] It should be noted that the specific volume of the buffer space 2121 can be set according to the actual situation to meet the requirements of the buffering effect. When the second liquid storage tank 2 is pre-filled with aerosol matrix at the factory, the buffer space 2121 can be reserved as required.

[0047] Furthermore, in a specific example, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in the second liquid storage chamber 2, at least a portion of the partition wall 211 is an arc-shaped structure extending circumferentially along the second liquid storage chamber 2, so that the inner cavity 213 enclosed by the arc-shaped structure is located inside the outer cavity 212. This fully utilizes the limited space in the second liquid storage chamber 2, allowing for a rational arrangement of the inner cavity 213 and the outer cavity 212, increasing their utilization rate, and adapting to the placement positions of the atomizing core assembly 3 and the replenishment interface 214. Preferably, when the second liquid storage chamber 2 as a whole adopts a cylindrical structure, the partition wall 211 adopts a cylindrical or near-cylindrical structure, so that the inner cavity 213 forms a cylindrical or near-cylindrical hollow chamber, and the outer cavity 212 forms an annular or near-annular hollow chamber. The inner cavity 213 and the outer cavity 212 are coaxially arranged so that the circumferential width of the outer cavity 212 remains essentially consistent. Of course, in practical applications, depending on the processing technology and assembly requirements, some irregular structures can also be set on the partition wall 211, for example... Figure 6 and Figure 7In the example, a mounting groove 2113 is provided on the side of the partition wall 211 corresponding to the liquid replenishment interface 214. The mounting groove 2113 is recessed towards the inner cavity 213 to reserve sufficient space in the area of ​​the outer cavity 212 that connects with the liquid replenishment interface 214, avoiding obstruction or interference with the liquid replenishment interface 214. In addition, a corresponding mounting protrusion 2112 can be provided on the partition wall 211 at a position away from the liquid replenishment interface 214. The mounting protrusion 2112 protrudes towards the outer cavity 212 to facilitate assembly and positioning with the first liquid suction element 32 of the atomizing core assembly 3. For example, in the first direction, a mounting groove 2113 is provided on one side of the partition wall 211, and a mounting protrusion 2112 is provided on the other side of the partition wall 211. Of course, the mounting protrusion 2112 can also be connected to the outer wall of the second liquid storage chamber 2 so that the outer cavity 212 is in a cut-off state at this point. The specific configuration can be determined according to the actual processing technology and assembly requirements.

[0048] Furthermore, in a specific example, such as Figures 4 to 7 As shown, multiple microporous structures 2111 on the partition wall 211 are spaced apart circumferentially along the inner cavity 213. Preferably, the multiple microporous structures 2111 are uniformly arranged circumferentially. For example, in the second direction, two microporous structures 2111 are symmetrically arranged on both sides of the partition wall 211. Figure 5 As shown, the outer cavity 212 contains an aerosol matrix, and the microporous structure 2111 is sealed by the aerosol matrix. When suction is performed, under negative pressure, one of the microporous structures 2111 is used for liquid inlet, so that part of the aerosol matrix in the outer cavity 212 passes through the microporous structure 2111 and enters the inner cavity 213. At the same time, the other microporous structure 2111 is used for gas outlet, so that part of the gas in the inner cavity 213 passes through the microporous structure 2111 and enters the outer cavity 212, thereby realizing gas-liquid replacement between the inner cavity 213 and the outer cavity 212, so that the inner cavity 213 and the outer cavity 212 still maintain pressure balance after the suction action. During use, with each suction action, a certain amount of aerosol matrix in the outer cavity 212 enters the inner cavity 213 to be heated and atomized by the atomizing core component 3, and a certain amount of gas enters the outer cavity 212 until the aerosol matrix in the outer cavity 212 is exhausted, exposing the microporous structure 2111. At this point, another suction action will generate negative pressure in the outer cavity 212, and the aerosol matrix in the first liquid storage chamber 1 will pass through the liquid replenishment interface 214 into the outer cavity 212, and seal the microporous structure 2111 again.

[0049] It is understandable that when gas in the inner cavity 213 enters the outer cavity 212, it occupies a certain space. If the microporous structure 2111 used for liquid inlet and the microporous structure 2111 used for exhaust are too close together, the gas entering the outer cavity 212 may occupy part of the space of the aerosol matrix used for liquid inlet, causing insufficient or discontinuous liquid inlet. By arranging multiple microporous structures 2111 at intervals along the circumference of the partition wall 211, a certain distance can be maintained between the liquid inlet area and the exhaust area, avoiding interference between them. The effect is even better when multiple microporous structures 2111 are evenly arranged along the circumference.

[0050] In further embodiments of this application, such as Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, a first connecting pipe 215 is provided at the top of the second liquid storage chamber 2, and the first connecting pipe 215 is connected to the air outlet pipe 111 of the first liquid storage chamber 1; an air guiding chamber 221 is also provided inside the second liquid storage chamber 2, and the air guiding chamber is connected to the outside. Correspondingly, the atomizing core assembly 3 includes an atomizing core 31 and a first liquid suction member 32. The atomizing core 31 is arranged in a height direction corresponding to the first connecting pipe 215, and the top of the atomizing core 31 is connected to the first connecting pipe 215 and the top of the atomizing core 31 is connected to the air guiding chamber 221. The first liquid suction member 32 is sleeved on the outside of the atomizing core 31. The first liquid suction member 32 can adsorb the aerosol matrix, so that the adsorbed aerosol matrix is ​​distributed on the surface of the atomizing core 31, so that the aerosol matrix is ​​heated by the atomizing core 31, causing the aerosol matrix to be atomized by heat and generate aerosol. External air can enter the atomizing core 31 through the air guide chamber 221 to mix with the generated aerosol to form an aerosol gas, which then flows along the first connecting pipe 215 to the outlet end of the air outlet pipe 111 for suction.

[0051] It should be noted that the first absorbent element 32 can be made of absorbent cotton or other porous structures with adsorption function. When the first absorbent element 32 adsorbs an aerosol matrix, the aerosol matrix can flow in the porous structure of the first absorbent element 32; when the first absorbent element 32 does not adsorb an aerosol matrix, the porous structure of the first absorbent element 32 can be used for gas flow.

[0052] Furthermore, in a specific example, such as Figures 3 to 5 and Figure 7As shown, a portion of the outer wall of the first suction element 32 abuts against the partition wall 211. A concave venting groove 321 is provided in the area corresponding to the microporous structure 2111 of the first suction element 32. That is, the area on the partition wall 211 where the microporous structure 2111 is provided does not directly contact the first suction element 32. Furthermore, in the height direction, the venting groove 321 communicates with the first connecting pipe 215, allowing the first connecting pipe 215 to communicate with the microporous structure 2111 through the venting groove 321. During suction, because the venting groove 321 is connected to the first connecting pipe 215, a negative pressure is generated in the venting groove 321. This allows the aerosol matrix in the outer cavity 212 to enter the inner cavity 213 under negative pressure. Alternatively, after the aerosol matrix in the outer cavity 212 is depleted, a passage is formed between the outer cavity 212, the venting groove 321, and the first connecting pipe 215, allowing the replenishment interface 214 to perform a replenishment operation under negative pressure, thereby replenishing the aerosol matrix into the outer cavity 212. It should be noted that the number of venting grooves 321 matches the number of microporous structures 2111, such as... Figure 7 In the example, the first liquid suction element 32 and the area corresponding to each microporous structure 2111 are provided with an exhaust groove 321.

[0053] Specifically, such as Figure 7 In the example, when the partition wall 211 is provided with an assembly protrusion 2112 and an assembly groove 2113, the first liquid suction member 32 is provided with a protrusion structure that matches the assembly protrusion 2112 and a groove structure that matches the assembly groove 2113.

[0054] Furthermore, in a specific example, such as Figures 4 to 10 As shown, the first liquid storage tank 1 includes a first housing 11, a first base 12, and a first sealing element 13. A suction nozzle 112 is formed at the top of the first housing 11, and the bottom of the first housing 11 is open, with an outlet pipe 111 located inside the first housing 11. The first base 12 is detachably connected to the bottom of the first housing 11. The first base 12 has a liquid replenishment hole 121 and a central hole through which the outlet pipe 111 passes. The liquid replenishment hole 121 is connected to the liquid replenishment interface 214 of the second liquid storage tank 2, and the outlet pipe 111 is connected to the first connecting pipe 215 of the second liquid storage tank 2. The first sealing element 13 is connected to the bottom of the first base 12. The first sealing element 13 has a liquid replenishment assembly hole 132 and an outlet pipe 131 to seal the connection between the liquid replenishment hole 121 and the liquid replenishment interface 214, as well as the connection between the outlet pipe 111 and the central hole and the first connecting pipe 215. Preferably, the first sealing element 13 is made of silicone.

[0055] Furthermore, in a specific example, such as Figure 4 , Figure 8 , Figure 9 as well as Figure 11As shown, the second liquid storage tank 2 includes a second housing 21, a second base 22, and a second sealing element 23. The top of the second housing 21 is provided with a second connecting pipe 33 and a liquid replenishment interface 214, and the bottom of the second housing 21 is open. A partition wall 211 is provided inside the second housing 21, and the top end of the partition wall 211 is connected to the inner top wall of the second housing 21. The second base 22 is detachably connected to the bottom of the second housing 21. The second sealing element 23 is located inside the second housing 21 and connected to the top of the second base 22. The top end of the second sealing element 23 abuts against the bottom end of the partition wall 211, thereby forming an inner cavity 213 and an outer cavity 212 within the second housing 21. The second sealing element 23 seals the top of the inner cavity 213 and the outer cavity 212. The second base 22 has an air guide cavity 221, and the bottom of the second base 22 has an air guide hole 222 communicating with the air guide cavity 221. The bottom of the atomizing core 31 passes through the second sealing member 23 and communicates with the air guide cavity 221, so as to form a seal between the atomizing core 31 and the air guide cavity 221 through the second sealing member 23. Preferably, the second sealing member 23 is made of silicone. The outer circumferential wall of the second sealing member 23 is provided with corresponding sealing protrusions to seal with the inner wall of the second housing 21; the middle of the second sealing member 23 is provided with an air guide assembly hole 231 through which the atomizing core 31 can pass, and the inner wall of the air guide assembly hole 231 is provided with corresponding sealing protrusions to seal with the outer wall of the atomizing core 31.

[0056] Furthermore, such as Figure 4 and Figure 6 As shown, the bottom end of the partition wall 211 has a corresponding notch. The notch is small in size. The second sealing member 23 abuts against the bottom end of the partition wall 211 and forms a microporous structure 2111 with the notch.

[0057] Furthermore, such as Figure 4 and Figure 11 The air guide cavity 221 is provided with a second liquid suction element 223 for adsorbing the aerosol matrix. When there is an excess of aerosol matrix in the atomizing core 31, causing some aerosol matrix to enter the air guide cavity 221, the second liquid suction element 223 can adsorb the aerosol matrix to prevent leakage of the aerosol matrix through the air guide hole 222.

[0058] Furthermore, such as Figure 4 , Figure 11 and Figure 12As shown, the atomizing core 31 specifically includes an atomizing tube 311, a liquid absorption structure 313, and a heating element 314. The liquid absorption structure 313 is a hollow cylindrical structure and is disposed inside the atomizing tube 311. The heating element 314 is connected to the inner sidewall of the liquid absorption structure 313. A liquid inlet 312 is provided on the sidewall of the atomizing tube 311 in the area corresponding to the liquid absorption structure 313, so that the aerosol matrix can enter the interior of the liquid absorption structure 313 through the liquid inlet 312 and be distributed on the surface of the heating element 314 through the liquid absorption structure 313. The heating element 314 has a corresponding pin structure 315 and is electrically connected to the power supply component through the pin structure 315, so that the heating element 314 heats the aerosol matrix when energized.

[0059] In practical applications, a second connecting tube 33 can be inserted into the atomizing tube 311 and connected to the first connecting tube 215 through the second connecting tube 33. Preferably, the second connecting tube 33 can be made of a low thermal conductivity material to avoid the second housing 21 from being damaged by high temperature due to contact between the atomizing tube 311 and the first connecting tube 215 or the surrounding inner wall.

[0060] Furthermore, such as Figure 4 , Figure 9 As shown, a corresponding conductive structure 224 is provided in the second base 22, and the pin structure 315 of the atomizing core 31 is connected to the conductive structure 224 so that when the atomizing device 100 is assembled with the power supply device, an electrical connection is formed between the conductive structure 224 and the power supply device.

[0061] In further embodiments of this application, such as Figures 1 to 5 , Figure 8 and Figure 9 As shown, the first liquid storage tank 1 and the second liquid storage tank 2 are detachably connected. For example, a corresponding assembly groove 122 is provided at the bottom of the first liquid storage tank 1, and a first snap-fit ​​structure 1221 is provided in the assembly groove 122. Correspondingly, a second snap-fit ​​structure 216 is provided at the top of the second liquid storage tank 2. The second snap-fit ​​structure 216 can extend into the assembly groove 122 and engage with the first snap-fit ​​structure 1221 to form a snap-fit ​​fixation between the first liquid storage tank 1 and the second liquid storage tank 2. When disassembly is required, the second snap-fit ​​structure 216 can be released from the first snap-fit ​​structure 1221 to separate the first liquid storage tank 1 and the second liquid storage tank 2. The first snap-fit ​​structure 1221 and the second snap-fit ​​structure 216 can be either a buckle or a slot. Correspondingly, the replenishment interface 214 of the second liquid storage tank 2 can be detachably connected to the replenishment hole 121 at the bottom of the first liquid storage tank 1. When the first liquid storage tank 1 and the second liquid storage tank 2 are connected and assembled, the replenishment interface 214 can extend into the replenishment hole 121.

[0062] In further embodiments of this application, such as Figures 1 to 5As shown, the area on the outer wall of the second liquid storage chamber 2 corresponding to the outer cavity 212 is a transparent structure, so that the outer cavity 212 can be visualized. During use, the user can directly observe the remaining amount of aerosol matrix in the outer cavity 212 without disassembly, so as to make liquid replenishment operation as needed.

[0063] An embodiment of the second aspect of this application provides an atomizing device 500, such as... Figure 13 and Figure 14 As shown, the atomizing device 500 includes the atomizing device 100 in any of the embodiments of the first aspect described above, and a power supply device 510. The power supply device 510 is electrically connected to the atomizing core assembly 3 of the atomizing device 100, and the power supply device 510 can supply power to the atomizing core assembly 3, so that the atomizing core assembly 3 heats up when energized, thereby heating the aerosol matrix.

[0064] Furthermore, such as Figure 14 In the example, the power supply device 510 includes a power supply housing 511 and an electrically connected battery 512 and an electrical control 513. The battery 512 supplies electrical energy, and the electrical control 513 controls the power supply to the battery 512. The electrical control 513 can be in the form of an electronic control board, on which corresponding control circuitry is provided. Specifically, the electrical control 513 is positioned above the battery 512 and connected to the conductive structure 224 at the bottom of the atomizing device 100 via corresponding electrode structures, thereby forming an electrical connection between the battery 512 and the atomizing core assembly 3.

[0065] Furthermore, the atomizing device 100 and the power supply device 510 are detachably connected to form a split structure, which facilitates assembly and user convenience.

[0066] Of course, in some examples, the power supply device 510 and the atomizing device 100 can also be set as an integrated structure, that is, the shell structure of the second liquid storage tank 2 can be set as an independent electronic control compartment for installing the battery 512 and the electronic control device 513. The specific configuration can be made according to the actual use needs.

[0067] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make several simple deductions, modifications, or substitutions based on the ideas presented.
