[0049] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0050] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may 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 may be directly connected to the other element or indirectly connected to the other element.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0052] References to "one embodiment," "some embodiments," or "an embodiment" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present invention. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, particular features, structures, or characteristics may be combined in any suitable manner.

[0053] In order to illustrate the technical solution of the present application, the following description is given with reference to specific drawings and embodiments.

[0054] In related technologies, the seal is generally set as a silicone plug. During the operation of the electronic atomization device, the seal is easily deformed, causing sealing failure, thereby causing leakage of the atomized liquid. If a silicone plug is used to achieve a better sealing effect, the silicone plug will be made thick and large, and the capacity of the electronic atomization device will eventually be greatly reduced.

[0055] In view of this, the present application provides a seal, a sealing structure of an electronic atomization device and an electronic atomization device. Since the seal includes a soft part and a hard part connected to each other, and the hardness of the hard part is greater than the hardness of the soft part, and the soft part includes a first sealing part, when the seal is placed in the liquid storage tank, the first sealing part can be used to abut against the inner wall of the liquid storage tank to form a liquid storage cavity between the bottom wall of the liquid storage tank and the seal. At the same time, since at least part of the hard part abuts against the side of the first sealing part away from the inner wall of the liquid storage tank, the first sealing part can be effectively avoided from being deformed, resulting in a gap between the first sealing part and the inner wall of the liquid storage tank, causing sealing failure, thereby leading to leakage of the atomized liquid in the liquid storage cavity.

[0056] Please refer to Figures 1 to 9 In a first aspect, an embodiment of the present application provides a sealing member 10 for a sealing structure 100 of an electronic atomization device 1000 .

[0057] The sealing structure 100 includes a liquid storage part 20, which is provided with a liquid storage tank 201, and the sealing part 10 is used to be accommodated in the liquid storage tank 201; the sealing part 10 includes a soft part 11 and a hard part 12 connected to each other, and the hardness of the hard part 12 is greater than the hardness of the soft part 11.

[0058] The soft portion 11 and the hard portion 12 may be connected by welding, bonding, screw connection, bolt connection or injection molding, etc. The soft portion 11 may have a certain elasticity and is more susceptible to elastic deformation than the hard portion 12.

[0059] The soft part 11 includes a first sealing part 111, which is used to abut against the inner wall of the liquid storage tank 201 so that a liquid storage cavity is formed between the bottom wall of the liquid storage tank 201 and the sealing member 10, and at least part of the hard part 12 abuts against the side of the first sealing part 111 away from the inner wall of the liquid storage tank 201.

[0060] The first sealing portion 111 abuts against the inner wall of the liquid storage tank 201, thereby sealing the sealing member 10 at its connection with the inner wall of the liquid storage tank 201 to form a liquid storage cavity for containing atomized liquid. Because at least a portion of the hard portion 12 abuts against the side of the first sealing portion 111 facing away from the inner wall of the liquid storage tank 201, at least a portion of the hard portion 12 can support the first sealing portion 111, thereby effectively preventing deformation of the first sealing portion 111, which could result in a gap between the first sealing portion 111 and the inner wall of the liquid storage tank 201 and cause sealing failure, thereby preventing leakage of atomized liquid in the liquid storage cavity.

[0061] From the above, it can be seen that the seal 10 provided in the embodiment of the present application includes a soft part 11 and a hard part 12 connected to each other, and the hardness of the hard part 12 is greater than the hardness of the soft part 11, and the soft part 11 includes a first sealing part 111. Therefore, when the seal 10 is placed in the liquid storage tank 201, the first sealing part 111 can be used to abut against the inner wall of the liquid storage tank 201, so that a liquid storage cavity is formed between the bottom wall of the liquid storage tank 201 and the seal 10. At the same time, since at least part of the hard part 12 abuts against the side of the first sealing part 111 away from the inner wall of the liquid storage tank 201, it can effectively avoid deformation of the first sealing part 111, which causes a gap between the first sealing part 111 and the inner wall of the liquid storage tank 201, resulting in sealing failure, thereby causing the problem of leakage of the atomized liquid in the liquid storage cavity.

[0062] The volume of the sealing member 10 provided in the embodiment of the present application can be made smaller, so as not to affect the capacity of the electronic atomization device 1000 .

[0063] Please refer to Figures 5 to 9 In this embodiment, the first sealing portion 111 includes a first connecting portion 1111 and a first strip portion 1112 protruding from the first connecting portion 1111. The first strip portion 1112 is used to abut against the inner wall of the liquid storage tank 201, and at least part of the hard portion 12 abuts against the side of the first connecting portion 1111 away from the first strip portion 1112.

[0064] By adopting the above solution, a better sealing effect can be achieved through the first strip portion 1112 , and the sealing member 10 can be conveniently placed in the liquid storage tank 201 .

[0065] Optionally, a plurality of first strip portions 1112 are provided, and the plurality of first strip portions 1112 are spaced apart along the depth direction of the liquid storage tank 201 .

[0066] Such a configuration can improve the sealing effect of the first strip portion 1112 and more effectively prevent the atomized liquid in the liquid storage cavity from leaking.

[0067] Please refer to Figures 5 to 9 In this embodiment, the sealing structure 100 includes an atomizer assembly 30, and the sealing member 10 is provided with a first recessed portion 101, which is used to accommodate the atomizer assembly 30; the soft portion 11 includes a second sealing portion 112, which defines the inner wall of the first recessed portion 101, and the second sealing portion 112 is used to abut against the atomizer assembly 30, and at least part of the hard portion 12 abuts against the side of the second sealing portion 112 away from the atomizer assembly 30.

[0068] By adopting the above solution, the second sealing portion 112 can be used to effectively seal the connection between the first recessed portion 101 and the atomizer assembly 30, and at least part of the hard portion 12 can effectively prevent the second sealing portion 112 from deforming, thereby causing a gap between the second sealing portion 112 and the atomizer assembly 30 and resulting in sealing failure.

[0069] It should be noted that the first recessed portion 101 may be a hole or a groove, and the atomizing assembly 30 is also connected to the liquid storage chamber, so that the atomized liquid can flow into the atomizing assembly 30 .

[0070] Optionally, the second sealing portion 112 includes a second connecting portion 1121 and a second strip portion 1122 protruding from the second connecting portion 1121. The second connecting portion 1121 and the second strip portion 1122 both extend continuously around the atomization assembly 30. The second strip portion 1122 is used to abut against the atomization assembly 30, and at least part of the hard portion 12 abuts against the side of the second connecting portion 1121 away from the second strip portion 1122.

[0071] With such a configuration, a better sealing effect can be achieved through the second strip portion 1122 , and the atomizer assembly 30 can be conveniently placed into the first recessed portion 101 .

[0072] It is understood that one or more second strip portions 1122 may be provided. When multiple second strip portions 1122 are provided, the sealing effect of the second sealing portion 112 may be improved.

[0073] Optionally, part of the hard portion 12 is located between the first sealing portion 111 and the second sealing portion 112 .

[0074] With this arrangement, a portion of the hard portion 12 can simultaneously support the first sealing portion 111 and the second sealing portion 112 , effectively preventing deformation of the first sealing portion 111 and the second sealing portion 112 , while also making the seal 10 more compact and smaller in size.

[0075] Please refer to Figures 5 to 9 In this embodiment, the sealing structure 100 includes a base 40, which is covered at the notch of the liquid storage tank 201. The base 40 is provided with a receiving groove 401. The end of the sealing member 10 away from the liquid storage tank 201 is used to be accommodated in the receiving groove 401. The soft portion 11 includes a third sealing portion 113, which is used to abut against the inner wall of the receiving groove 401 so that a connecting cavity 402 is formed between the bottom wall of the receiving groove 401 and the sealing member 10. At least part of the hard portion 12 abuts against the side of the third sealing portion 113 away from the inner wall of the receiving groove 401, and the atomization assembly 30 is connected to the connecting cavity 402.

[0076] By adopting the above-mentioned solution, the third sealing portion 113 can be used to effectively seal the connection between the inner wall of the receiving groove 401 and the sealing member 10, and at least part of the hard portion 12 can effectively prevent the third sealing portion 113 from deforming, thereby causing a gap between the third sealing portion 113 and the inner wall of the receiving groove 401 and resulting in sealing failure.

[0077] Optionally, the third sealing portion 113 includes a third connecting portion 1131 and a third strip portion 1132 protruding from the third connecting portion 1131, the third strip portion 1132 is used to abut against the inner wall of the accommodating groove 401, and at least part of the hard portion 12 abuts against the side of the third connecting portion 1131 away from the third strip portion 1132.

[0078] With such a configuration, a better sealing effect can be achieved through the third strip portion 1132 , and the sealing member 10 can be conveniently placed into the receiving groove 401 .

[0079] It is understood that one or more third strip portions 1132 may be provided. When multiple third strip portions 1132 are provided, the sealing effect of the third sealing portion 113 may be improved.

[0080] Optionally, the first recessed portion 101 is communicated with the communicating cavity 402 , and the atomizing assembly 30 is communicated with the communicating cavity 402 through the first recessed portion 101 .

[0081] Such an arrangement facilitates the communication between the atomizing assembly 30 and the communicating cavity 402 and makes the structure of the sealing member 10 more compact.

[0082] For example, a through hole may be provided in the first recessed portion 101 to achieve communication between the first recessed portion 101 and the communicating cavity 402 .

[0083] Optionally, part of the hard portion 12 is used to abut against the inner wall of the accommodating groove 401 .

[0084] With such a configuration, the third sealing portion 113 can be used to effectively seal the connection between the inner wall of the receiving groove 401 and the sealing member 10, and the partial hard portion 12 can be abutted against the inner wall of the receiving groove 401 to further improve the sealing effect of the connection between the inner wall of the receiving groove 401 and the sealing member 10.

[0085] It can be understood that part of the hard portion 12 is interference fit with the receiving groove 401 .

[0086] Please refer to Figures 5 to 9 In this embodiment, the liquid storage component 20 includes a main body 21 and an air inlet portion 22, the liquid storage tank 201 is arranged in the main body 21, the air inlet portion 22 is arranged inside the liquid storage tank 201, and an air inlet hole 2201 is provided inside the air inlet portion 22, and the air inlet hole 2201 is not connected to the liquid storage tank 201; the sealing component 10 is provided with a second recessed portion 102, the second recessed portion 102 is used to accommodate the air inlet portion 22, and the air inlet hole 2201 is connected to the connecting cavity 402 through the second recessed portion 102; the soft portion 11 includes a fourth sealing portion 114, the fourth sealing portion 114 defines the inner wall of the second recessed portion 102, the fourth sealing portion 114 is used to abut against the air inlet portion 22, and at least part of the hard portion 12 abuts against the side of the fourth sealing portion 114 away from the air inlet portion 22.

[0087] By adopting the above solution, the fourth sealing portion 114 can be used to effectively seal the connection between the second recessed portion 102 and the air inlet portion 22, and at least part of the hard portion 12 can effectively prevent the fourth sealing portion 114 from deforming, thereby causing a gap between the fourth sealing portion 114 and the air inlet portion 22 and resulting in sealing failure.

[0088] It should be noted that the second recessed portion 102 may be a hole or a groove, and external gas may enter the atomizer assembly 30 through the air inlet 2201 and the communicating cavity 402. A gas regulating assembly may be provided at the entrance of the air inlet 2201, and the gas regulating assembly is used to regulate the flow rate of the gas entering the air inlet 2201 from the entrance of the air inlet 2201, thereby realizing the top gas regulating function.

[0089] Optionally, the fourth sealing portion 114 includes a fourth connecting portion 1141 and a fourth strip portion 1142 protruding from the fourth connecting portion 1141. The fourth connecting portion 1141 and the fourth strip portion 1142 both extend continuously around the air inlet portion 22. The fourth strip portion 1142 is used to abut against the air inlet portion 22, and at least part of the hard portion 12 abuts against the side of the fourth connecting portion 1141 away from the fourth strip portion 1142.

[0090] With such a configuration, a better sealing effect can be achieved through the fourth strip portion 1142 , and the air inlet portion 22 can be conveniently placed into the second recessed portion 102 .

[0091] It is understood that one or more fourth strip portions 1142 may be provided. When multiple fourth strip portions 1142 are provided, the sealing effect of the fourth sealing portion 114 may be improved.

[0092] The first strip portion 1112 , the second strip portion 1122 , the third strip portion 1132 and the fourth strip portion 1142 are all arranged in a full circle, and the first connecting portion 1111 , the second connecting portion 1121 , the third connecting portion 1131 and the fourth connecting portion 1141 are all correspondingly arranged in a full circle.

[0093] Optionally, part of the hard portion 12 is located between the second sealing portion 112 and the fourth sealing portion 114 .

[0094] With this arrangement, a portion of the hard portion 12 can simultaneously support the second sealing portion 112 and the fourth sealing portion 114 , effectively preventing deformation of the second sealing portion 112 and the fourth sealing portion 114 , while also making the seal 10 more compact and smaller in size.

[0095] Optionally, the distance between the bottom wall of the accommodating groove 401 and the second recessed portion 102 is greater than the distance between the bottom wall of the accommodating groove 401 and the first recessed portion 101 .

[0096] Such a configuration can increase the space of the communicating cavity 402 between the bottom wall of the accommodating groove 401 and the second recessed portion 102 , thereby making the corresponding condensation chamber larger and achieving a balance between the atomizing core and the condensation effect of the atomizing assembly 30 .

[0097] It is understandable that a larger condensation chamber can provide conditions for the atomizer core of the 0.4Ω atomizer assembly 30 to work.

[0098] The soft portion 11 is made of silicone, rubber or TPU (Thermoplastic Polyurethane), and the hard portion 12 is made of PC (Polycarbonate), ABS (Acrylonitrile Butadiene Styrene) or PP (Polypropylene).

[0099] Such an arrangement can make the soft portion 11 and the hard portion 12 easier to manufacture.

[0100] Optionally, the soft part 11 and the hard part 12 are connected by injection molding.

[0101] Such a configuration makes it easy to connect the soft portion 11 and the hard portion 12 together without the need for assembly and is less likely to cause air or liquid leakage.

[0102] For example, the soft part 11 and the hard part 12 are directly injection-molded in a set of molds, so there is no risk of liquid or gas leakage between the soft part 11 and the hard part 12 , and the number of assembly steps is reduced.

[0103] Please refer to Figures 1 to 9 In the second aspect, an embodiment of the present application provides a sealing structure 100 of an electronic atomization device 1000, including a liquid storage component 20 and a sealing component 10 as in the first aspect, wherein the liquid storage component 20 is provided with a liquid storage tank 201, and the sealing component 10 is accommodated in the liquid storage tank 201.

[0104] The sealing structure 100 provided in the embodiment of the present application has a sealing member 10 including a soft portion 11 and a hard portion 12 connected to each other, and the hardness of the hard portion 12 is greater than the hardness of the soft portion 11, and the soft portion 11 includes a first sealing portion 111. Therefore, when the sealing member 10 is placed in the liquid storage tank 201, the first sealing portion 111 can be abutted against the inner wall of the liquid storage tank 201 to form a liquid storage cavity between the bottom wall of the liquid storage tank 201 and the sealing member 10. At the same time, since at least part of the hard portion 12 is abutted against the side of the first sealing portion 111 facing away from the inner wall of the liquid storage tank 201, deformation of the first sealing portion 111 can be effectively avoided, which may cause a gap between the first sealing portion 111 and the inner wall of the liquid storage tank 201 and cause sealing failure, thereby leading to leakage of the atomized liquid in the liquid storage cavity.

[0105] It should be noted that the sealing structure 100 provided in the embodiment of the present application may further include a liquid-absorbing cotton 50 provided on the base 40 .

[0107] The electronic atomization device 1000 provided in the embodiment of the present application has a sealing part 10 including a soft part 11 and a hard part 12 connected to each other, and the hardness of the hard part 12 is greater than the hardness of the soft part 11, and the soft part 11 includes a first sealing part 111. Therefore, when the sealing part 10 is placed in the liquid storage tank 201, the first sealing part 111 can be abutted against the inner wall of the liquid storage tank 201 to form a liquid storage cavity between the bottom wall of the liquid storage tank 201 and the sealing part 10. At the same time, since at least part of the hard part 12 is abutted against the side of the first sealing part 111 away from the inner wall of the liquid storage tank 201, it can effectively avoid deformation of the first sealing part 111, which may cause a gap between the first sealing part 111 and the inner wall of the liquid storage tank 201, resulting in sealing failure, thereby causing the problem of leakage of the atomized liquid in the liquid storage cavity.

[0108] It should be noted that the electronic atomization device 1000 provided in the embodiment of the present application may also include a shell 200, and the sealing structure 100 is arranged in the shell 200.
