[0038] Optionally, the oil storage shell 200 constitutes the suction nozzle of the electronic atomizer 1000. The electronic atomizer 1000 also includes an atomizer assembly 300. The oil storage shell 200 is also provided with an air outlet channel 202. The atomizer assembly 300 is installed in the sealing assembly 100. One end of the atomizer assembly 300 is connected to the oil storage chamber 201, and the other end of the atomizer assembly 300 is connected to the air outlet channel 202.

[0041] The electronic atomizer 1000 provided by the present invention is provided with an oil storage shell 200 and a sealing assembly 100 in an embodiment of the present invention. The oil storage shell 200 has an oil storage cavity 201. The sealing assembly 100 is sealed and connected to the oil storage shell 200. The sealing assembly 100 is used to seal the oil storage cavity 201, thereby reducing the operational difficulty of sealing the oil storage cavity 201 after filling the oil storage cavity 201 with oil, thereby improving the production speed.

[0042] Please refer to Figures 1 to 6 The present invention also provides a sealing assembly 100 for an electronic atomizer 1000. The sealing assembly 100 includes a shell 10 and a sealing structure 20. The shell 10 has an installation cavity 11 and an oil filling hole 12. The shell 10 includes a first end face 13 and a second end face 14 opposite to each other. The installation cavity 11 passes through the first end face 13, and the oil filling hole 12 passes through the second end face 14. The installation cavity 11 and the oil filling hole 12 are connected. The sealing structure 20 extends into the installation cavity 11 from the first end face 13 and is movable relative to the shell 10. The sealing structure 20 has a through oil filling channel 21. When the sealing structure 20 is in a first position relative to the shell 10, the oil filling channel 21 is connected to the oil filling hole 12. During the process of the sealing structure 20 moving from the first position to the second position, the sealing structure 20 moves toward the direction of the oil filling hole 12 and abuts against the shell 10, and the sealing structure 20 is deformed to block the oil filling channel 21 and the oil filling hole 12.

[0043] Specifically, the sealing structure 20 extends from the first end face 13 into the installation cavity 11 to complete the pre-installation of the sealing structure 20 and the shell 10, so that the electronic atomizer 1000 can be included as a whole and transported to the next level of production process for oil filling and sealing operations. There is no need to separately package and transport the aforementioned oil storage shell 200, shell 10 and sealing structure 20, which reduces the packaging cost and transportation cost of the electronic atomizer 1000 and improves the assembly speed of the sealing structure 20 and the economic benefits of the product.

[0044] Optionally, in the orthographic projection facing the first end face 13, the cross-sectional shape of any position of the receiving chamber 16 is rectangular, and may also be circular, elliptical, triangular, or other non-circular shapes, etc., without limitation. Optionally, the housing 10 is received in the oil storage shell 200 and is sealedly connected to the oil storage shell 200. Specifically, the outer peripheral surface of the housing 10 is sealedly connected to the oil storage shell 200, and the oil filling hole 12 is connected to the oil storage chamber 201. Optionally, the housing 10 also has an oil outlet 15 and a receiving chamber 16, the oil outlet 15 connects the oil storage chamber 201 and the receiving chamber 16, the atomizer assembly 300 is installed in the receiving chamber 16, and the receiving chamber 16 is also connected to the aforementioned air outlet channel 202. The oil in the oil storage chamber 201 can be transported to the atomizer assembly 300 through the oil outlet 15 to be heated to produce aerogel, and the aerogel is transported to the air outlet channel 202 through the receiving chamber 16 and discharged through the air outlet channel 202.

[0045] Optionally, when the sealing structure 20 is located at the first position, part of the sealing structure 20 is accommodated in the installation cavity 11, at this time, the outer peripheral surface of the sealing structure 20 is sealed and connected to the housing 10, and the oil injection hole 12 is connected to the outside through the oil injection channel 21. In the process of the sealing structure 20 moving from the first position to the second position, the sealing structure 20 abuts against the housing and deforms, so that the inner diameter of at least part of the oil injection channel 21 is gradually reduced to block the oil injection channel 21. When the sealing structure 20 is located at the second position, the oil injection channel 21 is blocked, and the sealing structure 20 extends into the oil injection hole 12 and is sealed and connected to the inner wall surface of the oil injection hole 12 to block the oil injection hole 12. Optionally, in the process of the sealing structure 20 moving from the first position to the second position, the sealing structure 20 may undergo plastic deformation or elastic deformation, without limitation.

[0046] Optionally, the sealing structure 20 has a third end face 22. When the sealing structure 20 is in the first position, the third end face 22 protrudes from the side of the first end face 13 facing away from the second end face 14. After the electronic atomizer 1000 completes oil filling, it can be contacted with the third end face 22 through external assembly equipment and push the sealing structure 20 from the first position to the second position to complete the sealing of the oil filling channel 21 and the oil filling hole 12.

[0047] In the production process of the electronic atomizer 1000 provided by the present invention, after the oiling operation is completed on multiple electronic atomizers 1000, the multiple electronic atomizers 1000 can be arranged on the assembly equipment, and the first end faces 13 and the third end faces 22 of the multiple electronic atomizers 1000 are all facing upward. The assembly equipment can simultaneously drive the multiple sealing structures 20 to move from the first position to the second position through the flat plate component, thereby realizing the sealing assembly process of the multiple electronic atomizers 1000, improving the production speed and production efficiency of the electronic atomizer 1000, and reducing the equipment cost of the assembly equipment.

[0048] By setting a sealing assembly 100, the sealing assembly 100 includes a housing 10 and a sealing structure 20, the housing 10 has a mounting cavity 11 and an oil injection hole 12, the housing 10 includes a first end face 13 and a second end face 14 opposite to each other, the mounting cavity 11 penetrates the first end face 13, the oil injection hole 12 penetrates the second end face 14, the mounting cavity 11 and the oil injection hole 12 are connected, the sealing structure 20 extends from the first end face 13 into the mounting cavity 11, and is movable relative to the housing 10, the sealing structure 20 has a through oil injection channel 21, wherein the sealing structure 20 is relative to the housing 1 When the sealing structure 20 is in the first position, the oil injection channel 21 is connected to the oil injection hole 12. When the sealing structure 20 moves from the first position to the second position, the sealing structure 20 moves toward the oil injection hole 12 and abuts against the housing 10. The sealing structure 20 is deformed to block the oil injection channel 21 and the oil injection hole 12, so that the sealing structure 20 can inject oil through the oil injection channel 21 and the oil injection hole 12 when the sealing structure 20 is in the first position. After the oil injection is completed, the sealing structure 20 is moved to the second position to block the oil injection channel 21 and the oil injection hole 12. The operation is simple and the production efficiency is improved.

[0049] Please refer to Figures 1 to 6 The shell 10 also includes a first fixing portion 17, and the sealing structure 20 includes a main body 23 and a second fixing portion 24, the main body 23 is connected to the second fixing portion 24, and when the sealing structure 20 is in the second position relative to the shell 10, the first fixing portion 17 and the second fixing portion 24 are connected and fixed.

[0050] Among them, when the sealing structure 20 is located in the first position, at least part of the main body and at least part of the second fixing part 24 are both located on the side of the first end face 13 facing away from the second end face 14, that is, at least part of the main body and at least part of the second fixing part 24 are both located in the outer shell of the housing 10, and the sealing structure 20 is movably connected to the housing 10. When the sealing structure 20 is located in the second position, the first fixing part 17 and the second fixing part 24 are connected and fixed, so that the sealing structure 20 is connected and fixed to the housing 10, so as to avoid the sealing structure 20 withdrawing from the installation cavity 11, resulting in sealing failure and leakage.

[0051] Optionally, there can be multiple first fixing parts 17 and multiple second fixing parts 24, and multiple first fixing parts 17 and multiple second fixing parts 24 are arranged one by one to improve the connection stability between the sealing structure 20 and the housing 10. Exemplarily, there are two second fixing parts 24, and the two second fixing parts 24 are respectively connected to the two end surfaces of the main body 23 opposite to each other in the second direction Y, and the two second fixing parts 24 are symmetrically arranged in the second direction Y.

[0052] Optionally, the main body and the second fixing portion 24 may be an integral structure, or may be detachably connected by means of snap connection, screw connection, riveting, etc., without limitation. Optionally, the first fixing portion 17 and the second fixing portion 24 may be connected and fixed by means of snap connection, screw connection, riveting, magnetic attraction, etc., without limitation.

[0053] By setting the shell 10 to also include a first fixing part 17, the sealing structure 20 includes a main body 23 and a second fixing part 24, and the main body 23 is connected to the second fixing part 24. When the sealing structure 20 is in the second position relative to the shell 10, the first fixing part 17 and the second fixing part 24 are connected and fixed, so that the sealing structure 20 can be connected and fixed to the shell 10 through the first fixing part 17 and the second fixing part 24, preventing the sealing structure 20 from withdrawing from the installation cavity 11 after blocking the oil filling channel 21 and the oil filling hole 12, causing sealing failure and then leakage.

[0054] Please refer to Figures 1 to 6 The first fixing portion 17 is a card slot provided on the inner wall of the mounting cavity 11, and the second fixing portion 24 is a buckle connected to the outer peripheral surface of the main body 23. The buckle includes a guide surface 241 and a clamping surface 242 which are sequentially connected in the first direction Z. From the direction in which the clamping surface 242 approaches the guide surface 241, the distance between the guide surface 241 and the outer peripheral surface of the main body 23 in the second direction Y gradually decreases. When the sealing structure 20 is in the second position relative to the shell 10, the clamping surface 242 abuts against the inner wall surface of the card slot in the first direction Z, and the first direction Z intersects with the second direction Y.

[0055] In the process of the sealing structure 20 moving from the first position to the second position, the guide surface 241 elastically abuts against the shell 10 and the buckle is elastically deformed so that the buckle extends into the card slot. Optionally, in the orthographic projection on the third direction X, the guide surface 241 and the card surface 242 are both planes, the inner wall surface of the card slot used to abut against the card surface 242 is also a plane, and the card surface 242 and the inner wall surface of the card slot used to abut against the card surface 242 extend along the second direction Y to reduce the difficulty of the manufacturing process of the sealing structure 20 and the shell 10. Optionally, the guide surface 241 can also be a curved surface protruding to the outside of the sealing structure 20, etc., without limitation. Optionally, the third direction X corresponds to the thickness direction of the electronic atomizer 1000. Optionally, the first direction Z corresponds to the length direction of the electronic atomizer 1000, the second direction Y corresponds to the width direction of the electronic atomizer 1000, and the sealing structure 20 moves along the first direction Z relative to the shell 10.

[0056] By setting the first fixing portion 17 as a slot opened on the inner wall of the installation cavity 11, and the second fixing portion 24 as a buckle connected to the outer peripheral surface of the main body 23, the buckle includes a guide surface 241 and a clamping surface 242 which are sequentially connected in the first direction Z. From the direction in which the clamping surface 242 approaches the guide surface 241, the distance between the guide surface 241 and the outer peripheral surface of the main body 23 in the second direction Y gradually decreases. When the sealing structure 20 is in the second position relative to the shell 10, the clamping surface 242 abuts against the inner wall surface of the slot in the first direction Z, and the first direction Z intersects with the second direction Y, so that the sealing structure 20 and the shell 10 can be fixed in the first direction Z by clamping the slot and the buckle. The structure is simple, and the difficulty of the production process of the sealing assembly 100 is reduced.

[0057] Please refer to Figures 1 to 6 The mounting cavity 11 includes a first chamber 111 and a second chamber 112 which are connected in sequence in a first direction Z. The first chamber 111 passes through the first end surface 13, and the second chamber 112 is connected to the oil filling hole 12. The inner wall of the first chamber 111 extends along the first direction Z. From the direction from the first chamber 111 to the second chamber 112, the size of the second chamber 112 in the second direction Y gradually decreases. During the process of the sealing structure 20 moving from the first position to the second position, the sealing structure 20 abuts against the inner wall of the second chamber 112, and the first direction Z intersects with the second direction Y.

[0058] In the process of the sealing structure 20 moving from the first position to the second position, under the restriction of the inner wall surface of the second chamber 112, part of the sealing structure 20 abuts against the inner wall of the second chamber 112 and is deformed, thereby blocking the oil filling channel 21 and the oil filling hole 12. When the sealing structure 20 is located at the second position, the sealing structure 20 penetrates the second chamber 112 and extends into the oil filling hole 12.

[0059] Optionally, the second chamber 112 includes a first inner wall surface 1121 and a second inner wall surface 1122 which are relatively arranged in the second direction Y. The first inner wall surface 1121 and the second inner wall surface 1122 are both smoothly connected to the inner wall surface of the first chamber 111, and are also smoothly connected to the inner wall surface of the oil filling hole 12. From the direction of the first chamber 111 to the second chamber 112, the spacing distance between the first inner wall surface 1121 and the second inner wall surface 1122 in the second direction Y gradually decreases. During the process of the sealing structure 20 moving from the first position to the second position, the sealing structure 20 abuts against the first inner wall surface 1121 and the second inner wall surface 1122.

[0060] Optionally, the inner wall surface of the second chamber 112 is smoothly connected to the inner wall surfaces of the first chamber 111 and the inner wall surfaces of the third chamber to reduce the friction between the shell 10 and the sealing structure 20 when the shell 10 and the sealing structure 20 move relative to each other, thereby reducing the wear of the shell 10 and the sealing structure 20.

[0061] The installation cavity 11 includes a first chamber 111 and a second chamber 112 which are connected in sequence in a first direction Z. The first chamber 111 passes through the first end face 13, and the second chamber 112 is connected to the oil injection hole 12. The inner wall of the first chamber 111 extends along the first direction Z. From the direction from the first chamber 111 to the second chamber 112, the size of the second chamber 112 in the second direction Y gradually decreases. During the movement of the sealing structure 20 from the first position to the second position, the sealing structure 20 abuts against the inner wall of the second chamber 112, and the first direction Z intersects with the second direction Y, so that the sealing structure 20 can be deformed under the action of the inner wall surface of the second chamber 112 during the movement from the first position to the second position to block the oil injection channel 21 and the oil injection hole 12.

[0062] Please refer to Figures 1 to 6 The sealing structure 20 includes a first deformable member 25, a main member 23 and a second deformable member 26 which are connected in sequence. The first deformable member 25 and the second deformable member 26 are arranged relatively spaced apart. During the movement of the sealing structure 20 from the first position to the second position, the first deformable member 25 and the second deformable member 26 both abut against the shell 10. The first deformable member 25 and the second deformable member 26 are deformed and approach each other to block the oil injection channel 21 and the oil injection hole 12.

[0063] Optionally, the main body 23 has an oil injection channel 21, which penetrates the main body 23 in the first direction Z, and the cavity enclosed by the first deformable member 25, the second deformable member 26 and the shell 10 communicates with the oil injection channel 21 and the oil injection hole 12. Optionally, the first deformable member 25 abuts against the aforementioned first inner wall surface 1121, and the second deformable member 26 abuts against the aforementioned second inner wall surface 1122. Optionally, the first deformable member 25 and the second deformable member 26 are both long arm structures, and one end of the first deformable member 25 connected to the main body 23 and one end of the second deformable member 26 connected to the main body 23 are used for deformation.

[0064] Optionally, a U-shaped groove 231 is enclosed at one end of the main body 23 close to the first deformable member 25 and the second deformable member 26, and the U-shaped groove 231 penetrates the main body 23 in the third direction X. The opening direction of the U-shaped groove 231 is the first direction Z and is toward the first deformable member 25 and the second deformable member 26, so that when the first deformable member 25 and the second deformable member 26 abut and deform against the shell 10, the inner wall of the U-shaped groove 231 may also be deformed along with the first deformable member 25 and the second deformable member 26 to prevent the first deformable member 25 and the second deformable member 26 from being broken from the main body 23.

[0065] Optionally, the two end faces of the main body 23 opposite to each other in the second direction Y are smoothly connected to the end face of the first deformation member 25 facing away from the second deformation member 26, and the end face of the second deformation member 26 facing away from the first deformation member 25, and the two end faces of the main body 23 opposite to each other in the third direction X are smoothly connected to the two end faces of the first deformation member 25 opposite to each other in the third direction X, and the two end faces of the second deformation member 26 opposite to each other in the third direction X.

[0066] Optionally, the first deformable member 25, the main member 23 and the second deformable member 26 are an integrated structure, and can also be detachably connected by means of snap connection, screw connection, riveting, etc., without limitation.

[0067] The sealing structure 20 includes a first deformable member 25, a main member 23 and a second deformable member 26 which are connected in sequence, and the first deformable member 25 and the second deformable member 26 are arranged relatively spaced apart. During the process of the sealing structure 20 moving from the first position to the second position, the first deformable member 25 and the second deformable member 26 both abut against the shell 10, and the first deformable member 25 and the second deformable member 26 are deformed and approach each other to block the oil injection channel 21 and the oil injection hole 12, so that the sealing structure 20 can block the oil injection channel 21 and the oil injection hole 12 by deforming the first deformable member 25 and the second deformable member 26, thereby reducing the pressure required for the sealing structure 20 to deform, so that the sealing structure 20 is easier to deform.

[0068] Please refer to Figures 1 to 6 The first deformable member 25 includes a first contact surface 251 facing away from the second deformable member 26, and the second deformable member 26 includes a second contact surface 261 facing away from the first deformable member 25. As the main body 23 approaches the first deformable member 25 and the second deformable member 26, the distance between the first contact surface 251 and the second contact surface 261 in the second direction Y gradually decreases.

[0069] Specifically, the first contact surface 251 is located at one end of the first deformable member 25 away from the main body 23, and the second contact surface 261 is located at one end of the second deformable member 26 away from the main body 23. During the process of the sealing structure 20 moving from the first position to the second position, the first contact surface 251 abuts against and slides relatively with the aforementioned first inner wall surface 1121, and the second contact surface 261 abuts against and slides relatively with the aforementioned second inner wall surface 1122.

[0070] By setting the first deformable member 25 to include a first contact surface 251 facing away from the second deformable member 26, and the second deformable member 26 to include a second contact surface 261 facing away from the first deformable member 25, the distance between the first contact surface 251 and the second contact surface 261 in the second direction Y gradually decreases in the direction from the main body 23 to the first deformable member 25 and the second deformable member 26, so that when the first deformable member 25 and the second deformable member 26 abut against the shell 10, the shell 10 can provide a force to the first contact surface 251 toward the second contact surface 261, and provide a force to the second contact surface 261 toward the first contact surface 251, so that the first deformable member 25 and the second deformable member 26 can be deformed to approach each other, thereby realizing the blocking of the oil injection channel 21 and the oil injection hole 12.

[0071] Please refer to Figures 1 to 6 The first deformable member 25 includes a first connecting portion 252 and a first contact portion 253. One end of the first connecting portion 252 is connected to the main body 23, and the other end of the first connecting portion 252 is connected to the first contact portion 253.

Optionally, the aforementioned first contact surface 251 is located on the first contact portion 253, and the second contact surface 261 is located on the second contact portion 263.

[0073] By setting the first deformable member 25 to include a first connecting portion 252 and a first contact portion 253, one end of the first connecting portion 252 is connected to the main body 23, and the other end of the first connecting portion 252 is connected to the first contact portion 253, and the distance between the first connecting portion 252 and the second deformable member 26 in the second direction Y is greater than the distance between the first contact portion 253 and the second deformable member 26 in the second direction Y, so that during the movement of the sealing structure 20 from the first position to the second position, the deformation of the first deformable member 25 and the second deformable member 26 is smaller, thereby preventing the first deformable member 25 and the second deformable member 26 from breaking.

[0074] Please refer to Figures 1 to 6The sealing structure 20 also includes a first sealing member 27 and a second sealing member 28. The first sealing member 27 is connected to the surface of the first deformable member 25 facing the second deformable member 26, and the second sealing member 28 is connected to the surface of the second deformable member 26 facing the first deformable member 25.

Optionally, when the sealing structure 20 is located at the second position, the first seal 27 and the second seal 28 both extend into the oil filling hole 12, and the end surface of the first seal 27 facing away from the second seal 28, the end surface of the second seal 28 facing away from the first seal 27, the two end surfaces of the first seal 27 facing away from each other in the third direction X, and the two end surfaces of the second seal 28 facing away from each other in the third direction X all abut against the inner wall surface of the oil filling hole 12 to achieve the blocking of the oil filling hole 12.

[0076] Optionally, the surface of the first seal 27 facing the second seal 28 protrudes from the first contact portion 253 in the second direction Y, and the surface of the second seal 28 facing the first seal 27 protrudes from the first contact portion 253 in the second direction Y, so as to further reduce the deformation of the first deformable member 25 and the second deformable member 26, and prevent the first deformable member 25 and the second deformable member 26 from breaking. Optionally, the first seal 27 and the second seal 28 can be made of a material that meets the structural strength and stable chemical properties, specifically silicone, rubber, nylon, etc., without limitation.

[0077] By setting the first seal 27 and the second seal 28, the first seal 27 is connected to the surface of the first deformable member 25 facing the second deformable member 26, and the second seal 28 is connected to the surface of the second deformable member 26 facing the first deformable member 25. When the sealing structure 20 is located at the second position relative to the shell 10, the first seal 27 and the second seal 28 abut to block the oil filling channel 21 and the oil filling hole 12, so that the sealing structure 20 has a better sealing effect on blocking the oil filling channel 21 and the oil filling hole 12, thereby reducing the risk of leakage.
