[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0037] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] In order to facilitate carrying, the volume of the electronic atomization device needs to be reduced as much as possible, resulting in the volume of the liquid storage chamber being limited, and the atomization medium in the liquid storage chamber is easily exhausted. When the atomization medium in the liquid storage chamber is exhausted, the electronic atomization device needs to be discarded as a whole, which will cause the problem of a short service life of the electronic atomization device and also increase the cost of using the electronic atomization device.

[0040] In order to solve the above problems, an embodiment of the present application provides an electronic atomization device, which is detachably connected to a liquid supply unit 100 having a liquid storage chamber 111 and an atomization body 200, so that after the atomization medium in the liquid storage chamber 111 is used up, the liquid supply unit 100 can be removed from the atomization body 200 and replaced with a new liquid supply unit 100, so that the atomization body 200 can be reused, thereby increasing the service life of the electronic atomization device and reducing the use cost of the electronic atomization device.

[0041] Please also read Figures 1 to 8 , the electronic atomization device provided in the embodiment of the present application is now described.

[0042] The electronic atomization device includes an atomization body 200 and a liquid supply unit 100 detachably arranged on the atomization body 200; the atomization body 200 has a liquid inlet 211; the liquid supply unit 100 includes a liquid storage tank 110 and a connecting member 120, the liquid storage tank 110 has a liquid storage cavity 111 and a liquid outlet 112 that are interconnected; the connecting member 120 is movably connected to the liquid storage tank 110, the connecting member 120 covers the liquid outlet 112 when the liquid supply unit 100 is separated from the atomization body 200, and the connecting member 120 connects the liquid outlet 112 and the liquid inlet 211 when the liquid supply unit 100 is assembled on the atomization body 200.

[0043] See also Figure 6 When the liquid supply unit 100 is assembled in the atomizer body 200, the liquid outlet 112 and the liquid inlet 211 are connected through the connecting piece 120, so that the atomized medium in the liquid storage chamber 111 can enter the atomizer body 200 through the liquid outlet 112 and the liquid inlet 211 to supply liquid to the atomizer body 200; when the atomized medium in the liquid storage chamber 111 is exhausted, the liquid supply unit 100 can be removed from the atomizer body 200, and at this time, the connecting piece 120 closes the liquid outlet 112, and the atomized medium in the liquid storage chamber 111 will not flow out.

[0044] The electronic atomization device in this embodiment is divided into an atomization body 200 and a liquid supply unit 100 detachably arranged on the atomization body 200. The liquid supply unit 100 includes a liquid storage tank 110 and a connecting piece 120. The liquid storage tank 110 has a liquid storage cavity 111 and a liquid outlet 112 which are interconnected. The atomization body 200 has a liquid inlet 211. After the liquid supply unit 100 is assembled on the atomization body 200, the connecting piece 120 connects the liquid outlet 112 and the liquid inlet 211. Therefore, the atomization body 200 can be supplied with atomization medium through the liquid supply unit 100. After the atomization medium in the liquid storage cavity 111 is used up, the liquid supply unit 100 can be removed from the atomization body 200 to replace it with a new one. In this way, the atomization body 200 can be reused, which increases the service life of the electronic atomization device and also increases the application cost of the electronic atomization device. At the same time, since the connecting piece 120 covers the liquid outlet 112 when the liquid supply unit 100 is separated from the atomizing body 200, the liquid storage chamber 111 is in a closed state when the liquid supply unit 100 is independently arranged, thereby preventing the liquid storage chamber 111 from leaking during transportation.

[0045] In one embodiment, see Figure 6 A first connecting port 121 is formed on the connecting member 120 . When the liquid supply unit 100 is assembled on the atomizing body 200 , the first connecting port 121 is located between the liquid outlet 112 and the liquid inlet 211 to connect the liquid outlet 112 and the liquid inlet 211 .

[0046] In one embodiment, see Figure 4 , Figure 6 and Fig.11 A locking structure 150 is provided between the connecting member 120 and the liquid storage tank 110 for locking the connecting member 120 at the position of the capping liquid outlet 112; an unlocking member 212 is provided on the atomizing body 200, and the unlocking member 212 unlocks the locking structure 150 when the liquid supply unit 100 begins to be loaded into the atomizing body 200.

[0047] When the liquid supply unit 100 is independently arranged, the locking structure 150 locks the connecting piece 120 in the position of covering the liquid outlet 112 to ensure that the liquid storage chamber 111 is closed; when the liquid supply unit 100 begins to be loaded into the atomizer body 200, the unlocking piece 212 on the atomizer body 200 just unlocks the locking structure 150, so that the connecting piece 120 can move on the liquid storage chamber 111 to the position connecting the liquid outlet 112 and the liquid inlet 211.

[0048] The setting of the locking structure 150 can ensure that the liquid storage chamber 111 is in a closed state, thereby preventing the liquid supply unit 100 from leaking when being transported alone. The unlocking member 212 is provided on the atomizing body 200, so that the locking structure 150 can be unlocked while the liquid supply unit 100 is assembled, without the need to unlock by hand or other tools, thereby reducing the difficulty of assembling the liquid supply unit 100.

[0049] In one embodiment, see Figure 4 , Figures 6 to 8 The connecting member 120 is slidably disposed on the liquid storage tank 110 along the first direction X; a plug hole 122 is formed on the connecting member 120, and the unlocking member 212 can be inserted into the plug hole 122 along the second direction Y to unlock the locking structure 150, and the second direction Y and the first direction X form an angle with each other.

[0050] When the liquid supply unit 100 is installed in the atomizer body 200, the unlocking member 212 can be inserted into the insertion hole 122 to unlock the locking structure 150. Since the second direction Y and the first direction X form an angle with each other, when the liquid storage tank 110 is pushed along the first direction X, the unlocking member 212 can have a pushing force on the connecting member 120 along the first direction X, thereby pushing the connecting member 120 along the first direction X, so that the connecting member 120 slides from the position of covering the liquid outlet 112 to the position connecting the liquid outlet 112 and the liquid inlet 211.

[0051] In general, when assembling the liquid supply unit 100, it is only necessary to move the liquid storage tank 110 along the second direction Y so that the unlocking member 212 is inserted into the insertion hole 122, so that the unlocking member 212 unlocks the locking structure 150, and then push the liquid storage tank 110 along the first direction X so that the liquid storage tank 110 is loaded into the atomizing body 200, and when the liquid storage tank 110 moves along the first direction X, the unlocking member 212 pushes the connecting member 120 in the opposite direction so that the connecting member 120 connects the liquid outlet 112 with the liquid inlet 211. When disassembling the liquid supply unit 100, it is only necessary to follow the opposite operation. The above-mentioned design of the embodiment of the present application makes the assembly operation of the liquid supply unit 100 simple, and can be operated with one hand, which is labor-saving and convenient.

[0052] In one embodiment, see Figure 4 and Figure 6, the first direction X and the second direction Y are perpendicular to each other. Specifically, the atomizing body 200 has an air outlet channel 217, the first direction X is the centerline direction of the air outlet channel 217, that is, the height extension direction of the atomizing body 200, and the second direction Y is the radial direction of the air outlet channel 217, that is, the horizontal direction. When the atomizing body 200 is placed vertically, the connecting member 120 is slidably arranged on the liquid storage tank 110 in the vertical direction, and the unlocking member 212 is inserted into the jack 122 in the horizontal direction. During assembly, the liquid storage tank 110 is first moved closer to the atomizing body 200 in the horizontal direction so that the unlocking member 212 is inserted into the jack 122, and then the liquid storage tank 110 is pushed vertically downward so that the liquid storage tank 110 is loaded into the atomizing body 200, and the unlocking member 212 pushes the connecting member 120 upward so that the connecting member 120 communicates with the liquid outlet 112 and the liquid inlet 211. It can be understood that in other embodiments, the first direction X and the second direction Y may also be 60 degrees, 70 degrees, 80 degrees or 90 degrees to each other, and the first direction X may also be at an angle to the center line of the air outlet channel 217 of the atomizing body 200, which is not a sole limitation here.

[0053] In one embodiment, see Fig.11 The unlocking member 212 is an inserting strip formed on the surface of the atomizing body 200 , and the inserting strip can be inserted into the inserting hole 122 along the second direction Y.

[0054] In one embodiment, see Figure 3 and Fig.11 A guide assembly 300 is provided between the liquid storage tank 110 and the atomizing body 200 for guiding the liquid storage tank 110 to be inserted into the liquid storage tank 110 along the first direction X. The arrangement of the unlocking member 212 and the insertion hole 122 can guide the liquid storage tank 110 to move along the second direction Y, and the arrangement of the guide assembly 300 can guide the liquid storage tank 110 to move along the first direction X to be inserted into the atomizing body 200, thereby reducing the difficulty of assembling the liquid storage tank 110 and ensuring the positioning accuracy of the liquid storage tank 110 in the atomizing body 200.

[0055] In one embodiment, see Figure 3 and Fig.11 The guide assembly 300 includes a guide hole 310 formed on the liquid storage bin 110 and a guide column 320 formed on the atomizing body 200, and the guide column 320 is inserted into the guide hole 310 to achieve assembly guidance and positioning of the liquid storage bin 110. It can be understood that in other embodiments of the present application, the guide hole 310 can also be formed on the atomizing body 200, and then the guide column 320 is formed in the liquid storage bin 110, which is not limited here.

[0056] In one embodiment, see Fig.11A panel 213 is formed on the atomizing body 200, and the panel 213 encloses a receiving groove 214. The bottom of the liquid storage tank 110 is received in the receiving groove 214. A step is formed on the outer wall of the liquid storage tank 110. The panel 213 is arranged around the outer wall of the liquid storage tank 110 and abuts against the step. The outer surface of the panel 213 is flush with the outer surface of the liquid storage tank 110. The provision of the receiving groove 214 can increase the connection reliability and connection stability between the liquid supply unit 100 and the atomizing body 200, and also makes the overall surface of the atomizing body 200 and the liquid supply unit 100 beautiful.

[0057] In one embodiment, see Figure 7 and Fig.11 , a detachable connection is formed between the liquid storage tank 110 and the atomizing body 200 by magnetic attraction. Specifically, a first magnetic component 400 is provided in the liquid storage tank 110, and a second magnetic component 500 is provided in the atomizing body 200. When the liquid storage tank 110 is loaded into the atomizing body 200, the first magnetic component 400 and the second magnetic component 500 attract each other, thereby ensuring the reliability of the connection between the liquid supply unit 100 and the atomizing body 200. In addition, the magnetic attraction method is simple, and can make the surface of the connection between the liquid storage tank 110 and the atomizing body 200 neat and beautiful. It can be understood that in other embodiments of the present application, the above-mentioned liquid storage tank 110 and the atomizing body 200 can also be snap-fitted, or removably connected by fastening with fasteners, which is not the only limitation here.

[0058] In a specific embodiment, see Figure 7 and Fig.11 A first mounting groove 113 is formed on the side of the liquid storage bin 110 facing the atomizing body 200, and the first magnetic member 400 is received in the first mounting groove 113; a second mounting groove 215 is formed on the side of the atomizing body 200 facing the liquid storage bin 110, and the second magnetic member 500 is received in the second mounting groove 215. When the liquid storage bin 110 approaches the atomizing body 200, the first magnetic member 400 and the second magnetic member 500 attract each other, so that the liquid storage bin 110 and the atomizing body 200 are reliably connected.

[0059] In one embodiment, see Figure 8 and Fig. 9 A slide groove 114 extending along the first direction X is formed on the liquid storage tank 110, and a slider 123 is formed on the connecting member 120. The slider 123 is slidably disposed in the slide groove 114, so as to guide the sliding of the connecting member 120.

[0060] In one embodiment, see Figure 8 and Fig. 9Two slide grooves 114 are formed on the liquid storage bin 110 and are spaced apart along the third direction Z. At least two sliders 123 are provided on opposite sides of the connecting member 120 along the third direction Z. The sliders 123 on both sides of the connecting member 120 are respectively slidably arranged in the two slide grooves 114, thereby ensuring the sliding stability of the connecting member 120 in the liquid storage bin 110.

[0061] In one embodiment, see Figure 8 A receiving groove 115 is formed on one side of the liquid storage tank 110 facing the atomizing body 200, and the connecting member 120 is received in the receiving groove 115. Two slide grooves 114 are respectively arranged on opposite sides of the receiving groove 115, thereby ensuring the installation stability of the connecting member 120 in the liquid storage tank 110.

[0062] In one embodiment, see Figure 4 and Figure 6 The locking structure 150 includes an elastic portion 151 formed on the liquid storage tank 110 and a matching portion 152 formed on the connecting member 120; the elastic portion 151 is abutted against and matched with the matching portion 152, and the unlocking member 212 can push the elastic portion 151 to disengage the elastic portion 151 from the matching portion 152 when the liquid supply unit 100 is installed into the atomizing body 200.

[0063] Among them, since the elastic part 151 is elastic, when the unlocking member 212 pushes the elastic part 151, the elastic part 151 can be separated from the matching part 152 to achieve the unlocking of the connecting member 120, and the connecting member 120 can slide to a position connecting the liquid outlet 112 and the liquid inlet 211 driven by the unlocking member 212. And since the elastic part 151 is elastic, when the liquid storage tank 110 is separated from the atomizing body 200, the elastic part 151 can be reset under its own elastic action to re-form a locking fit with the matching part 152 without manual reset.

[0064] In one embodiment, see Figure 4 and Figure 6 , a receiving groove 115 is formed on the liquid storage tank 110, and the connecting member 120 is slidably arranged in the receiving groove 115 along the vertical direction. The receiving groove 115 has a top side wall and a bottom side wall arranged oppositely; the matching portion 152 includes a matching surface 1522 facing the top side wall. When the connecting member 120 is in a position to cover the liquid outlet 112, the lower side of the connecting member 120 abuts against the bottom side wall of the receiving groove 115, and the elastic portion 151 abuts against the matching surface 1522, so that the vertical direction of the connecting member 120 is limited by the bottom side wall of the receiving groove 115 and the elastic portion 151. When the connecting member 120 is in a position to connect the liquid outlet 112 and the liquid inlet 211, the upper side of the connecting member 120 abuts against the top side wall of the receiving groove 115.

[0065] In one embodiment, see Fig. 9 The mating portion 152 is a protrusion protruding from the side of the connecting member 120 facing the liquid storage tank 110, and the mating surface 1522 is flush with the bottom surface of the insertion hole 122. When the unlocking member 212 is inserted into the insertion hole 122, it can push the elastic portion 151 along the second direction Y to separate the elastic portion 151 from the mating surface 1522, so that the connecting member 120 can slide upward.

[0066] In one embodiment, see Figure 6 , the side of the matching part 152 away from the matching surface 1522 is formed with a first guide surface 1521, and the side of the elastic part 151 facing the top side wall of the accommodating groove 214 is formed with a second guide surface 1513. When the liquid storage tank 110 is separated from the atomizing body 200, the elastic part 151 returns to the initial position, and the connecting member 120 slides down under its own gravity, so that the first guide surface 1521 squeezes the second guide surface 1513 of the elastic part 151. Since the elastic part 151 is elastic, the elastic part 151 retreats so that the matching part 152 is stuck under the elastic part 151, thereby achieving the clamping. In this embodiment, the connecting member 120 is reset by its own gravity. It can be understood that in other embodiments of the present application, when the connecting member 120 is not set to slide in the vertical direction, an elastic reset member can be connected between the connecting member 120 and the liquid storage tank 110, and the reset of the connecting member 120 is achieved by the elastic reset member.

[0067] In one embodiment, see Figure 4 The elastic part 151 includes an elastic arm 1511 and a clamping part 1512. One end of the elastic arm 1511 is connected to the liquid storage tank 110. The clamping part 1512 is formed on the other end of the elastic arm 1511. The clamping part 1512 is used to clamp and cooperate with the matching part 152. Through the setting of the elastic arm 1511, the elastic part 151 has elasticity.

[0068] In one embodiment, see Figure 6 and Fig.10 A sealing gasket 130 is abutted between the connecting piece 120 and the liquid storage tank 110. Through the setting of the sealing gasket 130, when the connecting piece 120 covers the liquid outlet 112, the sealing performance of the liquid outlet 112 is better to avoid leakage; at the same time, when the connecting piece 120 connects the liquid outlet 112 and the liquid inlet 211, the connection sealing performance between the liquid outlet 112 and the liquid inlet 211 is good, and the atomized medium will not leak from the gap between the connecting piece 120 and the liquid storage tank 110.

[0069] For details, please refer to Figure 4The connecting member 120 is formed with a first connecting port 121, and the sealing gasket 130 is formed with a second connecting port 131, and the first connecting port 121 is connected to the second connecting port 131. When the connecting member 120 covers the liquid outlet 112, the sealing gasket 130 covers the liquid outlet 112, and when the connecting member 120 connects the liquid outlet 112 with the liquid inlet 211, the liquid outlet 112, the second connecting port 131, the first connecting port 121 and the liquid inlet 211 are connected in sequence.

[0070] In one embodiment, see Fig. 9 and Fig.10 A limiting column 124 is formed on the connecting member 120, and a limiting hole 132 is formed on the sealing gasket 130. The limiting column 124 and the limiting hole 132 are interference-fitted with each other, so that the sealing gasket 130 is fixedly installed on the connecting member 120, and the sealing gasket 130 can slide on the liquid storage tank 110 together with the connecting member 120.

[0071] For details, please refer to Fig. 9 and Fig.10 A plurality of limiting posts 124 are formed on the connector 120, and each limiting post 124 is arranged around the first liquid inlet 211; a plurality of limiting holes 132 are formed on the sealing gasket 130, and each limiting hole 132 is arranged around the second liquid inlet 211; each limiting post 124 corresponds to each limiting hole 132 in an interference fit, thereby ensuring the connection reliability between the sealing gasket 130 and the connector 120.

[0072] In one embodiment, see Figure 4 and Figure 6 , a convex rib 216 arranged around the liquid inlet 211 is formed on the surface of the atomizing body 200; a groove 125 arranged around the liquid outlet 112 is formed on the surface of the connecting piece 120; the convex rib 216 and the groove 125 are plugged and matched, and a sealing ring 140 is abutted between the convex rib 216 and the inner wall of the groove 125. Among them, the arrangement of the convex rib 216 and the groove 125 enables the liquid supply unit 100 and the atomizing body 200 to be accurately positioned at the liquid outlet 112 and the liquid inlet 211, and the arrangement of the sealing ring 140 enables the liquid supply unit 100 and the atomizing body 200 to be sealed and connected, thereby preventing the atomized medium from leaking at the connection between the liquid supply unit 100 and the atomizing body 200.

[0073] Specifically, the sealing ring 140 is in interference fit with the inner wall of the groove 125. When assembling the liquid supply unit 100, the sealing ring 140 can be pre-embedded in the groove 125 to form the liquid supply unit 100. When the liquid supply unit 100 is installed in the atomizer body 200, the rib 216 is inserted into the groove 125 along the second direction Y, and the outer wall of the rib 216 is in contact with the inner wall of the sealing ring 140, so that the groove 125 and the rib 216 are sealed and plugged. When the liquid storage bin 110 is pushed downward along the first direction X, the rib 216 and the unlocking member 212 jointly push the connecting member 120 to slide upward relative to the liquid storage bin 110.

[0074] In this embodiment, the groove 125 is formed on the surface of the connecting member 120, so that the surface of the connecting member 120 is flat and has no protruding structure, so that the surface of the liquid supply unit 100 is flat and easy to carry. In other embodiments of the present application, the groove 125 can also be formed on the surface of the atomizing body 200, and the rib 216 is formed on the surface of the connecting member 120, which is not limited here.

[0075] In one embodiment, see Figure 3 , Figure 4 and Figure 6 The liquid outlet 112 is located at the bottom of the liquid storage chamber 111, and the bottom inner wall 116 of the liquid storage chamber 111 is at least partially tilted downward from the edge toward the liquid outlet 112. By tilting the bottom inner wall 116 of the liquid storage chamber 111 downward, the atomized medium in the liquid storage chamber 111 can be guided toward the liquid outlet 112, so that the atomized medium can be fully utilized and the atomized medium can be avoided from being retained in the liquid storage chamber 111 and wasted.

[0076] Optionally, the bottom inner wall 116 of the atomization chamber 226 is an inclined straight surface or an inclined curved surface.

[0077] In one embodiment, see Figure 4 , Figure 6 and Figure 8 The liquid storage tank 110 includes a tank body 117 and a tank cover 118, the tank body 117 and the tank cover 118 are detachably connected, and a sealing ring 119 is abutted between the tank body 117 and the tank cover 118; the liquid outlet 112 is formed on the tank cover 118, and the connecting member 120 is movably arranged on the tank cover 118. Among them, by dividing the liquid storage tank 110 into two parts, the tank body 117 and the tank cover 118, the processing difficulty of the tank body 117 is simplified; at the same time, the setting of the sealing ring 119 makes the connection between the tank body 117 and the tank cover 118 have good sealing performance, reducing the leakage of the atomized medium.

[0078] In one embodiment, see Figure 3 and Figure 5The atomizing body 200 is formed with an atomizing chamber 226, the liquid inlet 211 is connected to the atomizing chamber 226, an atomizing core 223 is provided in the atomizing chamber 226, the atomizing core 223 is blocked at the liquid inlet 211, and the atomizing core 223 has an atomizing surface facing the liquid storage tank 110 and a liquid inlet surface facing the liquid storage chamber 111. In this embodiment, by directly connecting the liquid inlet 211 to the atomizing chamber 226, the atomizing medium transported from the liquid storage chamber 111 can directly flow to the liquid inlet surface of the atomizing core 223 and be atomized by the atomizing core 223, the generated aerosol flows into the atomizing chamber 226, and is carried out by the airflow transported by the airflow channel running through the atomizing chamber 226 for the user to inhale, thereby improving the atomization efficiency and simplifying the structure of the atomizing body 200.

[0079] In one embodiment, see Figures 3 to 6 The liquid supply unit 100 and the atomizing body 200 are assembled and arranged along the second direction Y. The liquid storage chamber 111, the liquid outlet 112, the first connecting port 121, the second connecting port 131, the liquid inlet 211 and the atomizing chamber 226 are sequentially distributed along the second direction Y. The liquid inlet surface and the atomizing surface of the atomizing core 223 are arranged opposite to each other along the second direction Y. In addition, the bottom inner wall 116 of the liquid storage chamber 111 is inclined, so that the atomizing medium in the liquid storage chamber 111 can quickly flow to the atomizing core 223 under the action of its own gravity and be atomized by the atomizing core 223.

[0080] In one embodiment, see Figure 3 , the atomizing body 200 includes a main housing 210 and an atomizing assembly 220, and the atomizing assembly 220 includes an atomizing seat 221 and an atomizing cover 222. Among them, an air outlet channel 217 is formed at the top center of the main housing 210, the atomizing seat 221 and the atomizing cover 222 are respectively installed on the bottom of the main housing 210, and the atomizing cover 222 is covered on the atomizing seat 221, and the atomizing seat 221 and the atomizing cover 222 are enclosed to form an atomizing chamber 226. An air outlet 227 is formed at the top of the atomizing cover 222, and the air outlet 227 is connected to the air outlet channel 217. The liquid inlet 211 is formed on the side wall of the main housing 210, and a through groove 228 connected to the atomizing chamber 226 is formed on the atomizing cover 222, and the liquid inlet 211 is connected to the through groove 228.

[0081] In one embodiment, see Figure 3The atomizing body 200 further includes a sealing sleeve 224, which is sleeved on the top of the atomizing cover 222, the outer peripheral wall of the atomizing cover 222 and part of the outer peripheral wall of the atomizing seat 221. The top center of the sealing sleeve 224 seals the connection between the gas outlet 227 and the gas outlet channel 217, and the outer peripheral wall of the sealing sleeve 224 is used to seal the main housing 210, the atomizing seat 221 and the atomizing cover 222. The sealing sleeve 224 is also arranged to abut against the periphery of the liquid outlet 112, so as to ensure that the atomized medium of the liquid inlet 211 flows directly into the through groove 228 and the atomizing chamber 226.

[0082] In one embodiment, see Figure 6 A sealing member 225 is provided on the inner wall of the atomizing core 223 and the atomizing cover 222. Through the setting of the sealing member 225, the atomizing medium flowing in from the through groove 228 flows to the liquid inlet surface of the atomizing core 223 and is atomized by the atomizing core 223, and does not flow directly into the atomizing chamber 226 from the gap between the atomizing core 223 and the atomizing cover 222.

[0083] In one embodiment, see Figure 3 The atomizer body 200 further includes a bottom shell 230, which is arranged in a sleeve arrangement with the main shell 210, and has a storage cavity 231, in which a battery 240 is arranged. Two electrodes 270 are connected to the atomizer core 223, and the other ends of the two electrodes 270 are respectively connected to the battery 240, so that the atomizer core 223 can be powered by the battery 240.

[0084] In one embodiment, see Figure 3 The bottom of the bottom shell 230 is formed with an air inlet 232, and the atomizer seat 221 is formed with a mounting cavity 2221 on one side facing the storage cavity 231. A microphone seat 250 is mounted in the mounting cavity 2221, and a microphone 260 is mounted on the microphone seat 250. A through hole connecting the storage cavity 231 and the mounting cavity 2221 is formed on the microphone seat 250, and an air inlet 2222 is formed at the bottom of the atomizer seat 221. When the user sucks on the mouthpiece, the external airflow enters the storage cavity 231 from the air inlet 232 and is sensed by the microphone 260. The battery 240 starts to supply power to the atomizer core 223, and the atomizer core 223 atomizes the atomization medium into an aerosol. The airflow entering the atomizer cavity 226 from the mounting cavity 2221 carries the aerosol and leads it out from the air outlet channel 217 for inhalation.
