Aerosol-generating device

Abstract

The present application relates to the technical field of atomization devices. Air enters the top of an air intake channel in a housing, the bottom of the air intake channel is in communication with the bottom of an atomization cavity, and a first e-liquid groove is provided at the bottom of the air intake channel and can collect aerosol-generating e-liquid leaking from the atomization cavity, thus reducing leakage of the aerosol-generating e-liquid. Since an atomizer hole communicates the atomization cavity with a box body air hole in the top of a box body of a battery box, and a bottom hole opening of the box body air hole is in communication with the space where an air pressure sensing device is located, the air pressure sensing device in the battery box acquires the air pressure in the atomization cavity by means of the box body air hole in the top of the box body and the atomizer hole. A second e-liquid groove in the top of the box body also can collect the aerosol-generating e-liquid leaking from the first e-liquid groove, and when the level of the aerosol-generating e-liquid collected in the first e-liquid groove reaches the position of a top opening of the atomizer hole, the aerosol-generating e-liquid leaks out of the first e-liquid groove but does not directly enter the box body air hole. By means of the second e-liquid groove collecting the e-liquid, the effect of the leaked aerosol-generating e-liquid on the battery box can be further reduced.

Description

An aerosol generating device Technical Field

[0001] The utility model relates to the technical field of atomizing devices, in particular to an aerosol generating device for atomizing aerosol generating oil. Background Art

[0002] The aerosol generating device can atomize aerosol generating oil to generate aerosol for the user to inhale. The aerosol generating device includes an atomizer, which includes a housing and an atomizer core. The housing has an oil storage chamber, which is connected to the atomizer core to supply the aerosol generating oil into the atomizer core. The atomizer core has an atomizer chamber and an electric heater located in the atomizer chamber to heat the aerosol generating oil. The electric heater heats the aerosol generating oil to generate an aerosol. Currently, this type of aerosol generating device usually adopts a bottom air intake method. The bottom of the atomizer is provided with an air inlet hole that communicates with the atomizer chamber. The air inlet hole is used to replenish air into the atomizer chamber when the user inhales the aerosol. Due to the limited lifespan of the atomizer, the atomizer in some aerosol generating devices is a disposable design. In order to facilitate the replacement of the atomizer, the aerosol generating device also includes a battery box. The battery box and the atomizer are fixed together by magnetic attraction for easy replacement. In order to reduce costs, the air pressure sensing device used to control the operation of the electric heating element according to the puff frequency is usually installed in the battery box. In this way, the battery box needs to have an air hole communicating with the atomization chamber so that the air pressure sensing device can sense the pressure changes in the atomization chamber.

[0003] When the current aerosol generating device is used, the oil in the atomizer is prone to seepage and leaking from the air inlet at the bottom. In addition, when the aerosol generated in the atomizing chamber contacts the colder wall, condensed oil is easily generated in the atomizing chamber. This part of the oil is also prone to leaking from the air inlet at the bottom. After the aerosol-generated oil leaks, it contaminates the battery box, affecting its use and easily reducing the life of the battery box. Utility Model Content

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted under different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0032] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0033] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0034] The end herein refers to a region at the end, which can be understood as a region with a certain length at the end, and is not limited to the end face.

[0035] In some embodiments, referring to FIG. 1 to FIG. 8 , the aerosol generating device includes an atomizer 1 and a battery box 2 located at the lower side of the atomizer 1 .

[0036] Please refer to Figures 1 to 4. The atomizer 1 includes a housing 11 and an atomizer core 12. The top of the housing 11 has a nozzle hole 111, and the housing 11 has an air inlet channel 112. The atomizer core 12 is arranged in the housing 11. The atomizer core 12 has an atomization chamber 121 and an electric heating element (not shown in the figure). The electric heating element is arranged in the atomization chamber 121 and is used to heat the aerosol-generating oil entering the atomizer core 12 to generate aerosol. The housing 11 also has an oil storage chamber 113, which is used to store aerosol-generating oil. The atomizer core 12 has an oil inlet 126 connected to the oil storage chamber 113. The aerosol-generating oil stored in the oil storage chamber 113 can enter the atomizer core 12 through the oil inlet 126.

[0037] To reduce oil leakage from the atomizer core 12, the air inlet channel 112 has an air inlet 1121 at the top of the housing 11 for external air to enter. The air inlet channel 112 is connected to the bottom of the atomizing chamber 121, and the mouthpiece hole 111 is connected to the top of the atomizing chamber 121. This prevents aerosol-generating oil from leaking out of the air inlet 1121.

[0038] The battery box 2 includes a box body 21 and an air pressure sensing device 22 located inside the box body 21. The power supply circuit between the battery box 2 and the atomizer 1 is connected or disconnected in response to the sensing result of the air pressure sensing device 22. In one embodiment, ventilation is required between the atomizer 1 and the battery box 2 located on the lower side of the atomizer 1 so that the air pressure sensing device 22 can sense the air pressure in the atomization chamber 121. The top of the box body 21 has a box body air hole 211, and the outer shell 11 has an atomizer hole 115 that connects the bottom of the air inlet channel 112 with the box body air hole 211. The bottom opening 2112 of the box body air hole 211 is in communication with the space where the air pressure sensing device 22 is located, so that the air pressure sensing device 22 can sense the air pressure in the atomization chamber 121 through the atomizer hole 115 and the box body air hole 211.

[0039] To reduce leakage of aerosol-generating oil, a first oil tank 116 is disposed at the bottom of the air inlet channel 112. The first oil tank 116 is used to collect aerosol-generating oil. The top opening 1151 of the atomizer hole 115 is higher than the bottom of the first oil tank 116. This prevents the aerosol-generating oil from leaking directly through the atomizer hole 115. When the aerosol-generating oil level in the first oil tank 116 reaches the height of the top opening 1151 of the atomizer hole 115, the aerosol-generating oil can be discharged through the top opening 1151 of the atomizer hole 115. This also protects the higher-positioned components of the atomizer 1 from being contaminated by the aerosol-generating oil and affecting their performance. A second oil tank 212 is disposed at the top of the box body 21. The top opening 2111 of the box body air hole 211 is higher than the bottom of the second oil tank 212. The bottom opening 1152 of the atomizer hole 115 faces the bottom of the second oil tank 212 and is staggered left and right with the top opening 2111 of the box body air hole 211. In this way, the aerosol-generating oil flowing out of the bottom opening 1152 of the atomizer hole 115 can directly enter the second oil tank 212.

[0040] In the aerosol generating device of the present application, the channel air inlet 1121 is located at the top of the housing 11. The air inlet channel 112 of the housing 11 takes in air from the top, and the bottom is connected to the bottom of the atomizing chamber 121. Since the atomizer hole 115 connects the atomizing chamber 121 with the box body air hole 211, and the bottom hole 2112 of the box body air hole 211 is connected to the space where the air pressure sensing device 22 is located, the air pressure sensing device 22 in the battery box 2 can sense the air pressure in the atomizing chamber 121 through the box body air hole 211 and the atomizer hole 115 at the top of the box body 21, so that the power supply circuit is connected or disconnected in response to the sensing result of the air pressure sensing device 22. The first oil tank 116 is arranged at the bottom of the air inlet channel 112 to collect the aerosol generating oil leaked from the atomizing chamber 121. The second oil tank 212 at the top of the box body 21 can also collect the aerosol generating oil leaked from the first oil tank 116. When the liquid level of the aerosol generating oil collected in the first oil tank 116 reaches the position of the top opening 1151 of the atomizer hole 115, the aerosol generating oil leaks out of the first oil tank 116. Since the bottom opening 1152 of the atomizer hole 115 faces the bottom of the second oil tank 212 and is staggered to the left and right of the top opening 2111 of the box body air hole 211, the aerosol generating oil leaked from the first oil tank 116 will not directly enter the box body air hole 211, but will be stored in the second oil tank 212. In summary, the aerosol generating device in this application reduces the leakage of aerosol generating oil through the top air intake and the first oil tank 116. The collection of oil by the second oil tank 212 can reduce the impact of the leaked aerosol generating oil on the battery box 2 and improve the service life of the battery box 2.

[0041] It should be noted that the top and bottom in the present application are described when the atomizer 1 is in use. When in use, the nozzle hole 111 is at the top and the atomizing chamber 121 is at the bottom.

[0042] In the present application, the power supply circuit responds to the sensing result of the air pressure sensing device 22 in a variety of feasible ways: for example, the air pressure sensing device 22 is an air pressure sensor, the power supply circuit includes a controller and a circuit switch, and the controller controls the circuit switch to be on or off after receiving the air pressure sensing signal from the air pressure sensing device 22, thereby connecting or disconnecting the power supply circuit. For another example, the air pressure sensing device 22 is an air pressure sensing switch, which is connected when the air pressure sensing device 22 senses a drop in the air pressure in the atomizing chamber 121, at which time the power supply circuit is connected; and is disconnected when the air pressure sensing device 22 senses that the atomizing chamber 121 is not being sucked, at which time the power supply circuit is connected.

[0043] Furthermore, in one embodiment, referring to Figures 3, 4, and 7, the battery case 2 includes a battery 24 within the case body 21, and a power supply circuit (not shown) electrically connects the electric heating element and the battery 24. In one embodiment, the air pressure sensing device 22 is a pressure sensing switch, and the air pressure sensing device 22 is located on the power supply circuit. In one embodiment, the air pressure sensing device 22 is an air pressure sensor capable of sensing pressure changes within the atomizing chamber 121. Specifically, the air pressure sensing device 22 is a microphone.

[0044] In one embodiment, during use, the aerosol generating device needs to control the operation of the electric heating element based on the frequency of puffing. That is, when the aerosol is puffed, the electric heating element needs to operate to atomize the aerosol-generating oil, and when the aerosol is not puffed, the electric heating element needs to stop heating the aerosol-generating oil. To facilitate the control of the operation of the electric heating element, the present application uses an air pressure sensing device 22 to sense whether the atomizing chamber 121 is being puffed. The power supply circuit responds to the sensing result of the air pressure sensing device 22 to open or close the circuit between the electric heating element and the battery 24.

[0045] When the aerosol is inhaled through the nozzle hole 111, the gas in the atomizing chamber 121 is sucked in and the pressure drops. At this point, the air pressure sensing device 22 senses the drop in air pressure, i.e., it senses that the atomizing chamber 121 is being inhaled. Based on this sensing result from the air pressure sensing device 22, the power supply circuit is turned on, and the electric heater begins operating, heating and atomizing the aerosol-forming oil to produce the aerosol. When the aerosol is no longer inhaled, the air pressure in the atomizing chamber 121 returns to normal, and the air pressure sensed by the air pressure sensing device 22 is atmospheric pressure, i.e., it senses that the atomizing chamber 121 is not being inhaled. Based on this sensing result from the air pressure sensing device 22, the power supply circuit is turned off, and the electric heater stops operating, ceasing to heat and atomize the aerosol-forming oil.

[0046] Regarding the atomizer core 12, in some embodiments, the atomizer core 12 can adopt any feasible method in the prior art. Since the improvements in this application do not involve the specific structure of the atomizer core 12, in order to avoid redundant description, this embodiment only briefly describes the structure of the atomizer core 12 with reference to the accompanying drawings. Referring to Figures 3 and 4, the atomizer core 12 includes an atomizer core housing 122 and an atomizer core bracket 123. The atomizer core bracket 123 is inserted into the atomizer core housing 122. The atomizer core housing 122 is installed in the housing 11. The electric heating element is a heating mesh sleeve located in the atomizer core bracket 123. A first oil guide member 124 is located between the atomizer core bracket 123 and the atomizer core housing 122, and a second oil guide member 125 is located between the atomizer core bracket 123 and the heating mesh sleeve. The first and second oil guide members 124 and 125 can be made of porous adsorption materials, such as oil-absorbing cotton. The first oil guide member 124 is coated on the atomizer core bracket 123, and the second oil guide member 125 is coated on the heating mesh sleeve. The heating mesh sleeve is in the atomizing chamber 121. After the heating mesh sleeve contacts the second oil guide member 125, the aerosol-generating oil in contact with the heating mesh sleeve is heated and atomized to produce an aerosol. In some other embodiments, the electric heating element can adopt any feasible method, such as a spiral heating wire, or a plurality of circumferentially arranged heating meshes. In this application, please refer to Figure 3. The oil inlet 126 is on the atomizing core shell 122, and the oil in the oil storage chamber 113 can enter the atomizing chamber 121 through the oil inlet 126. The atomizing core bracket 123 has a bracket through hole 1231, so that the oil can enter the atomizing chamber 121 through the bracket through hole 1231 and be adsorbed by the second oil guide member 125.

[0047] Regarding the air intake channel 112, there are many feasible ways for the air intake channel 112 to be in the shell 11. For example, the air intake channel 112 is integrally formed in the shell 11. For example, please refer to Figures 3 and 4. The air intake channel 112 is composed of multiple sections. The specific structure of the air intake channel 112 in Figures 3 and 4 will be described in detail below.

[0048] Furthermore, to facilitate the arrangement of the atomizer hole 115, in one embodiment, referring to Figures 3 and 4, the bottom of the first oil groove 116 is provided with an upwardly projecting first protrusion 117, the atomizer hole 115 extends onto the first protrusion 117, and the top opening 1151 of the atomizer hole 115 is located on top of the first protrusion 117. Placing the top opening 1151 of the atomizer hole 115 on top of the first protrusion 117 in the first oil groove 116 simplifies the structure of the atomizer hole 115. In some other embodiments, the top opening of the atomizer hole 115 may also be located on the wall of the first oil groove 116.

[0049] Specifically, in one embodiment, please refer to Figures 3 and 4, the atomizer hole 115 is L-shaped, including a first hole segment 1153 and a second hole segment 1154, the first hole segment 1153 extends up and down, the second hole segment 1154 is perpendicular to the first hole segment 1153, and the second hole segment 1154 is connected to the top of the first hole segment 1153.

[0050] Similarly, in one embodiment, referring to Figures 3 and 4 , the bottom of the second oil groove 212 is provided with an upwardly projecting second protrusion 213. The housing air hole 211 extends onto the second protrusion 213, and the top opening 2111 of the housing air hole 211 is located on top of the second protrusion 213. Specifically, the housing air hole 211 is a straight hole. In some other embodiments, the top opening 2111 of the housing air hole 211 may also be located on the wall of the second oil groove 212.

[0051] Furthermore, in one embodiment, referring to Figures 3 and 4, the top of the box body 21 also has a mounting groove 214 with a notch facing away from the atomizer 1, the mounting groove 214 is arranged opposite to the second oil groove 212, the bottom opening 2112 of the box body air hole 211 is connected to the mounting groove 214, the air pressure sensing device 22 is sealed and installed in the mounting groove 214, and the box body air hole 211 extends to the bottom of the mounting groove 214. In this way, the air pressure sensing device 22 can be directly installed in the mounting groove 214, the installation structure is simple, and the path between the air pressure sensing device 22 and the atomizing chamber 121 is short, reducing the pressure sensing error. In some other embodiments, the air pressure sensing device 22 can also be arranged in any other feasible position, such as in the middle or bottom of the box body 21.

[0052] Specifically, in one embodiment, the air pressure sensing device 22 is a microphone, and the air pressure sensing device 22 is sealed with the mounting groove 214 through a sealing gasket 23. The sealing gasket 23 has a sealing gasket hole 231 that exposes the air pressure sensing part of the air pressure sensing device 22.

[0053] Furthermore, in one embodiment, referring to Figures 3 and 4, the oil storage chamber 113 is connected to the atomizer core 12, and the air inlet channel 112 includes an air inlet section 1122 and a connecting section 1123. The air inlet section 1122 runs through the oil storage chamber 113, and the air flow direction of the air inlet section 1122 is opposite to the air flow direction in the atomizer chamber 121. The connecting section 1123 is connected to the bottom end of the atomizer chamber 121. Compared with the arrangement of the air inlet section 1122 and the oil storage chamber 113 with left and right intervals, the air inlet section 1122 running through the oil storage chamber 113 can make the overall structure more compact. In some other embodiments, the air inlet section 1122 can also be arranged with left and right intervals from the oil storage chamber 113.

[0054] Furthermore, in one embodiment, referring to Figures 3 and 4 , the housing 11 includes a base 118 and a sealing seat 119. The sealing seat 119 is located above the first oil groove 116. The base 118 and the sealing seat 119 form a connecting section 1123, which separates the connecting section 1123 from the oil reservoir 113. Furthermore, in one embodiment, an oil absorber 13 is provided in the first oil groove 116 and / or the second oil groove 212. The oil absorber 13 absorbs oil to prevent it from escaping the atomizer 1. Specifically, in one embodiment, the oil absorber 13 is an oil-absorbing cotton pad.

[0055] Specifically, please refer to Figure 3. The housing 11 includes a shell 1101, a nozzle end cover 1102 at one end of the shell 1101, and a base 118 at the other end of the shell 1101. The first oil groove 116 is on the base 118. The lower end of the atomizing core 12 is mounted on the base 118 and is sealed with the sealing seat 119. There is a nozzle 1103 on the nozzle end cover 1102, and the nozzle hole 111 is on the nozzle 1103. The channel air inlet 1121 is on the nozzle end cover 1102. Specifically, the sealing seat 119 is made of silicone. The space between the sealing seat 119 and the base 118 encloses the connecting section 1123 of the air inlet channel 112 for gas to enter the atomizing chamber 121. The sealing seat 119 separates the connecting section 1123 from the oil storage chamber 113.

[0056] The housing 11 includes a vent tube 1104 integrally formed with the nozzle end cap 1102. The lower end of the vent tube 1104 is inserted into and seals against a sealing seat 119. The oil suction member 13 in the first oil tank 116 is located below the vent tube 1104. The inner hole of the vent tube 1104 forms part of the air inlet section 1122.

[0057] Furthermore, in order to adapt to the needs of different users and make the air intake size of the air intake channel 112 adjustable, in one embodiment, please refer to Figures 3, 4 and 8, the atomizer 1 includes an air regulating valve plate 14, which is installed on the side of the nozzle end cover 1102 facing away from the atomizing chamber 121. The air regulating valve plate 14 can rotate relative to the nozzle end cover 1102, and the axis of the rotating shaft of the air regulating valve plate 14 extends along the thickness direction of the nozzle end cover 1102. By rotating the air regulating valve plate 14, the area of ​​the channel air inlet 1121 communicating with the outside world can be changed to adjust the air intake size of the air intake channel 112. The air regulating valve plate 14 takes up less space, making the atomizer 1 more compact.

[0058] Specifically, the air regulating valve plate 14 and the suction nozzle 1103 are arranged at intervals, and the extension direction of the rotation axis of the air regulating valve plate 14 is consistent with the extension direction of the suction nozzle hole 111.

[0059] Furthermore, in one embodiment, referring to Figures 3 and 4 , the air inlet channel 112 includes an end cap air inlet hole 1105, which is located on the nozzle end cap 1102. The air inlet of the end cap air inlet hole 1105 forms a channel air inlet 1121. The atomizer 1 includes a valve plate sealing gasket 15 located between the air regulating valve plate 14 and the nozzle end cap 1102. The valve plate sealing gasket 15 has a valve plate sealing gasket air channel 151 that extends through the end cap air inlet hole 1105. The air regulating valve plate 14 changes the area of ​​the channel air inlet 1121 that is connected to the outside world by adjusting the area of ​​the valve plate sealing gasket air channel 151 that is connected to the outside world.

[0060] The valve plate sealing gasket 15 is in sealing contact with the air regulating valve plate 14 and the suction nozzle end cover 1102, so that the air regulating valve plate 14 can be sealed when rotating. At the same time, the valve plate sealing gasket 15 provides resistance to the air regulating valve plate 14, and the air regulating valve plate 14 is not easy to shake and is easier to maintain in the adjusted position.

[0061] Furthermore, in one embodiment, please refer to Figures 1 to 6, the aerosol generating device includes a nebulizer cover 3, which is used to cover the nebulizer 1. The nebulizer cover 3 includes a cover top 31 and a cover tube 32. The cover top 31 is located at one end of the cover tube 32, and the other end of the cover tube 32 forms a cover opening for the nebulizer 1 to enter; the cover top 31 has a nozzle through-hole for the nozzle 1103 to pass through and extend out of the nebulizer cover 3.

[0062] The aerosol generating device also includes a first magnetic member 4 and a second magnetic member 5. To facilitate assembly and disassembly of the atomizer cover 3, in some embodiments, as shown in FIG5 , the first magnetic member 4 is disposed on the atomizer cover 3, and the second magnetic member 5 is disposed on the housing 11. After the atomizer cover 3 is placed on the atomizer 1, the first magnetic member 4 and the second magnetic member 5 attract each other in the extension direction of the cover tube 32. The mutual attraction between the first magnetic member 4 and the second magnetic member 5 maintains the relative position of the atomizer cover 3 to the atomizer 1.

[0063] It should be noted that although the first magnetic member 4 on the atomizer cover 3 and the second magnetic member 5 on the housing 11 are attracted to each other, the atomizer cover 3 is not required to be in contact with the atomizer 1. The atomizer cover 3 and the atomizer 1 can be in contact or not. When the atomizer cover 3 and the atomizer 1 are not in contact, the atomizer cover 3 is fixed to the battery compartment 2 by magnetic attraction.

[0064] The atomizer cover 3 can be formed in any feasible form: for example, the atomizer cover 3 is formed in one piece; for another example, the cover top 31 and the cover tube 32 of the atomizer cover 3 are assembled separately and fixed by bonding, welding or fasteners.

[0065] The aerosol generating device can shield the atomizer 1 by adopting the atomizer cover 3, thereby overcoming the problem of the atomizer 1 having a messy appearance and a single form design, and increasing the variety of design forms.

[0066] Furthermore, in one embodiment, referring to Figures 4 to 6, the cover tube 32 includes a top abutting surface 321 for abutting the battery box 2; after the atomizer cover 3 is covered on the atomizer 1, the first magnetic member 4 and the second magnetic member 5 are arranged at intervals in the extension direction of the cover tube 32, and the atomizer cover 3 and the atomizer 1 are arranged at intervals in the extension direction of the cover tube 32, so that the top abutting surface 321 can abut against the battery box 2 in the extension direction of the cover tube 32.

[0067] The atomizer cover 3 engages the battery box 2 via the abutting surface 321. That is, there is room for movement between the first magnetic member 4 and the second magnetic member 5 in the direction of the extension of the cover tube 32. Furthermore, there is room for movement between the atomizer cover 3 and the atomizer 1 in the direction of the extension of the cover tube 32. The atomizer cover 3 and the atomizer 1 are not in close contact in the direction of the extension of the cover tube 32. This facilitates installation of the atomizer cover 3 and reduces the installation precision requirements for the atomizer cover 3 compared to a situation where the atomizer cover 3 and the atomizer 1 are in close contact. Furthermore, this installation method of the atomizer cover 3 also makes it easy to remove the atomizer cover 3 separately for operations such as refueling the atomizer 1 and adjusting the air intake.

[0068] To facilitate disassembly of the atomizer 1, in one embodiment, as shown in Figures 3 and 4 , the atomizer 1 and battery compartment 2 are also secured magnetically. The magnetic attraction between the battery compartment 2 and the atomizer 1 is greater than the magnetic attraction between the atomizer 1 and the atomizer cover 3. This makes it easier to separate the atomizer 1 from the battery compartment 2 when the atomizer cover 3 is removed.

[0069] Specifically, in one embodiment, referring to Figures 3 and 4 , the aerosol generating device includes a third magnetic member 6 and a fourth magnetic member 7. The third magnetic member 6 is fixed to the bottom of the atomizer 1, and the fourth magnetic member 7 is fixed to the top of the battery compartment 2. Under the action of the third magnetic member 6 and the fourth magnetic member 7, the battery compartment 2 and the atomizer 1 are magnetically fixed.

[0070] There are magnetic fixing grooves on the top of the battery box 2 and the bottom of the shell 11. The fourth magnetic member 7 is fixed in the magnetic fixing groove on the top of the battery box 2, and the third magnetic member 6 is fixed in the magnetic fixing groove on the bottom of the shell 11.

[0071] It should be noted that the magnetic member described in this application can be either a permanent magnet or a metal material that can be attracted by a permanent magnet. Of course, at least one of the two magnetic members that are attracted to each other should be a permanent magnet. On this basis, the magnetic member is not limited to additional parts. For example, when the atomizer cover 3 is made of a metal material that can be attracted by a permanent magnet, the first magnetic member 4 can be composed of a part of the atomizer cover 3. This situation also belongs to the case where the first magnetic member 4 is configured on the atomizer cover 3. Similarly, the second magnetic member 5 and the third magnetic member 6 can also be formed as part of the housing 11, and the fourth magnetic member 7 can also be formed as part of the box body 21 of the battery box 2.

[0072] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
