Examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0026] In the description of the present application, it should be understood that if terms such as "center", "middle part", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it should not be construed as a limitation to the present application. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0027] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0028] During the process from the completion of manufacturing and leaving the factory of the electronic atomization device until it reaches the user's hands, due to various environmental changes faced during product transportation, such as the increase or decrease in temperature, the gas inside the electronic atomization device expands or contracts, resulting in a drastic fluctuation in the internal air pressure. This will increase the sealing difficulty of each sealing position and increase the risk of leakage of the atomization medium. Such leakage will not only cause waste of the atomization medium, but also reduce the user experience when the leaked liquid flows to the outer surface of the electronic atomizer. Even after the atomization medium leaks, it may flow into the electronic components, causing the electronic components to malfunction and reducing the reliability of the electronic atomization device.

[0029] To solve this problem, in the first aspect of the present application, an electronic atomization device 200 is provided. Please refer to Figure 1 and Figure 2 , the electronic atomization device 200 includes an atomizer 201 and a sealing plug 100. The atomizer 201 is provided with an air flow channel 202, an air inlet 2021 and an air outlet 2022 communicating with the air flow channel 202. The sealing plug 100 is detachably inserted into at least one of the air inlet 2021 and the air outlet 2022. The sealing plug 100 is inserted into the air flow channel 202, which can reduce the air pressure fluctuation of the electronic atomization device 200 caused by environmental temperature changes and improve the sealing performance of each sealing position in the electronic atomization device 200. This is because the electronic atomization device 200 has cavities inside, including an atomization cavity and an air flow channel 202 (such as an air inlet channel, an air outlet channel, etc.), and these cavities will retain a certain amount of air. After the electronic atomization device 200 leaves the factory until it is used by the user, the gas will be sealed in the cavities. During the transportation of the electronic atomization device 200, due to the change of the environmental temperature, for example, the increase of the environmental temperature causes the gas to expand, thereby increasing the air pressure inside the electronic atomization device 200. When the air pressure changes too much, the sealing of the sealing positions in the electronic atomizer will fail, resulting in a leakage problem. In the present application, by inserting the sealing plug 100 into the air flow channel 202, the volume of the cavity in the electronic atomization device 200 can be reduced, thereby reducing the volume of the air retained in the electronic atomization device 200. According to the ideal gas state equation PV = nRT, it can be known that an ideal gas satisfies V 1 / V 2 = T 2 / T1 , which means that during the same temperature change process, the smaller the initial volume of the gas is set, the smaller its volume change will be, and thus the smaller the air pressure change in the cavity will be. Therefore, this solution uses the sealing plug 100 to reduce the initial volume of the internal gas expansion of the electronic atomization device 200, thereby reducing the air pressure fluctuation inside the electronic atomization device 200 during the temperature change process, making the internal air pressure less susceptible to the influence of external environmental temperature changes, improving the sealing reliability of the sealing position inside the electronic atomization device 200, helping to prevent liquid leakage from the source, and improving the sealing performance of the electronic atomization device 200 during transportation.

[0030] Optionally, the electronic atomization device 200 can be provided with two sealing plugs 100, one inserted into the air inlet 2021 and the other inserted into the air outlet 2022, which can further reduce the cavity volume inside the electronic atomization device 200, thereby reducing the initial volume of the internal gas expansion. Of course, in other examples, only one of the air inlet 2021 or the air outlet 2022 can be provided with the sealing plug 100, which is not limited here.

[0031] The other components and operations of the electronic atomization device 200 are already recorded in the relevant technologies for those of ordinary skill in the art and will not be described in detail here. The structure of the sealing plug 100 will be introduced below.

[0032] Please refer to Figures 3 to 5, a second aspect of the present application provides a sealing plug 100, which can be used to plug into the air flow channel 202. The sealing plug 100 includes an end cover portion 10 and a rod portion 20. The rod portion 20 is disposed on one side of the end cover portion 10, and the rod portion 20 is provided with a liquid storage structure 21. The liquid storage structure 21 includes a liquid storage groove 211 disposed at one end of the rod portion 20 away from the end cover portion 10, and an adsorbent 2110 is provided in the liquid storage groove 211. By using the liquid storage structure 21, when the sealing plug 100 is plugged into the air flow channel 202, on the one hand, the liquid leakage of the air flow channel 202 can be absorbed and stored by the liquid storage structure 21. For example, the adsorbent 2110 in the liquid storage groove 211 can adsorb and hold the atomization medium in the adsorbent 2110, preventing the atomization medium from flowing in the air flow channel 202; on the other hand, the sealing plug 100 can seal the air flow channel 202, blocking the atomization medium from flowing out of the air flow channel 202 to the outer surface of the electronic atomization device 200, ensuring that the outer shell of the electronic atomization device 200 will not be stained with the atomization medium during user use, and improving the user experience. When the user first uses the electronic atomization device 200, the sealing plug 100 is pulled out. During the process of the sealing plug 100 leaving the ventilation pipe, the atomization medium that has penetrated into the air flow channel 202 during liquid leakage can be taken out together with the sealing plug 100. The user does not need to clean the air flow channel 202 a second time, and no liquid atomization medium will flow out of the air outlet 2022 when the electronic atomization device 200 is first used, thereby improving the experience of using the electronic atomization device 200.

[0033] Optionally, the adsorbent 2110 can be made of materials with a certain fiber structure such as cotton and linen to facilitate the adsorption of liquid leakage, or a porous body with pores can be used for adsorption, and this is not limited here. Exemplarily, when the sealing plug 100 is plugged into the electronic atomization device 200, its end cover portion 10 is located outside the air flow channel 202, and the rod portion 20 is located inside the air flow channel 202. When the user first uses the electronic atomization device 200, the end cover portion 10 located outside the air flow channel 202 is convenient for the user to grasp and pull out the sealing plug 100 from the air flow channel 202.

[0034] In order to further improve the storage effect of the liquid storage structure 21 on the atomization medium, in some embodiments, the liquid storage structure 21 further includes a groove 22 provided on the outer peripheral side surface of the rod portion 20. The groove 22 can provide more space for accommodating the atomization medium, improving the adsorption effect of the sealing plug 100 on liquid leakage without increasing the volume of the sealing plug 100, thereby preventing the atomization medium from flowing to the outer surface of the electronic atomization device 200 and improving the sealing effect.

[0035] Optionally, the groove 22 can be arranged in various forms on the outer periphery of the rod body portion 20. In some examples, the groove 22 includes a helical groove extending axially along the rod body portion 20. By arranging the helical groove to extend axially along the rod body portion 20, a continuous liquid storage space can be formed, making full use of the outer surface of the rod body portion 20, increasing the liquid storage capacity of the liquid storage structure 21, and improving the anti-leakage effect. During the process of pulling out the sealing plug 100, the helical surface of the helical groove forms a certain angle with the pulling-out direction, which helps to bring out the atomizing medium in the air flow channel 202. The helical groove can be a helical groove with a constant pitch or a variable pitch. In some other examples, the groove 22 includes a strip-shaped groove extending axially along the rod body portion 20. The strip-shaped groove has a simple structure and can also form a continuous liquid storage space along the axis of the rod body portion 20 to ensure the liquid storage effect. Exemplarily, the groove 22 can be arranged as a plurality of strip-shaped grooves, and the plurality of strip-shaped grooves are arranged at intervals along the circumferential direction of the rod body portion 20. Each strip-shaped groove can be continuously arranged or discontinuously arranged along the axis of the rod body portion 20. In still some other examples, the groove 22 includes an annular groove arranged circumferentially along the rod body portion 20. The annular groove can form a liquid storage space along the circumferential direction of the rod body portion 20 and helps to bring out the atomizing medium during the process of pulling out the silica gel plug. The annular groove can be arranged in the form of a closed loop or an open loop. Optionally, the groove 22 includes a plurality of annular grooves, and the plurality of annular grooves are arranged at intervals along the axis of the rod body portion 20. By arranging a plurality of annular grooves along the axis of the rod body portion 20, in this way, if liquid leakage occurs at any part along the axis of the air flow channel 202, the corresponding annular groove can timely absorb and accommodate the atomizing medium, further improving the anti-leakage effect.

[0036] It can be understood that the groove 22 in the above examples can be simultaneously arranged on the outer periphery of the rod body portion 20. For example, an annular groove and a strip-shaped groove can be arranged simultaneously, or only one of the grooves 22 can be arranged. There is no limitation here.

[0037] In some embodiments, please refer to Figure 6 , when the sealing plug 100 is inserted into the air flow channel 202, a liquid storage gap 23 is formed between the outer surface of the rod body portion 20 and the inner wall surface of the air flow channel 202. That is to say, when the sealing plug 100 is inserted into the air flow channel 202, the outer surface of the rod body portion 20 does not fit tightly against the inner wall surface of the air flow channel 202, and there is a certain gap between the two. In this way, when the electronic atomization device 200 leaks liquid and the atomizing medium flows to the air flow channel 202, the atomizing medium can penetrate into and fill the liquid storage gap 23. After the liquid storage gap 23 is filled with the atomizing medium, a liquid seal effect can be formed by the surface tension of the liquid, thereby preventing the atomizing medium from further leaking. The atomizing medium filled in the liquid storage gap 23 can also play a role in blocking the air flow channel 202 from the external environment, preventing the fragrance of the internal atomizing medium from overflowing and dissipating, so that the taste of the atomizing medium in the liquid storage cavity of the electronic atomizing medium remains fresh and the user experience is improved.

[0038] In some embodiments, an annular protrusion 24 is further provided on the outer peripheral side of one end of the rod body 20 close to the end cover portion 10. The annular protrusion 24 is used for sealing connection with the inner wall of the air flow channel 202. The annular protrusion 24 can play a role in sealing the liquid storage gap 23, further improving the sealing effect. When the sealing plug 100 is inserted into the air flow channel 202, the annular protrusion 24 abuts against the inner wall surface of the air flow channel 202, thereby sealing the air flow channel 202. By arranging the annular protrusion 24 at one end close to the end cover portion 10, in this way, there is enough space at the end of the rod body 20 far from the end cover portion 10 to arrange the groove 22 to provide enough liquid storage space. On this basis, when the liquid storage space is not sufficient to adsorb the leaked liquid, the annular protrusion 24 is used to prevent the atomization medium from flowing out of the air flow channel 202.

[0039] In some embodiments, the rod body 20 and the end cover portion 10 are of an integrally formed structure, which can improve the overall strength and sealing performance of the sealing plug 100.

[0040] In some embodiments, the cross-sectional area of the rod body 20 gradually increases in the direction of the end cover portion 10. On the one hand, this helps the sealing plug 100 to be inserted into the air flow channel 202 or pulled out from the air flow channel 202, reducing the insertion and extraction resistance. On the other hand, a liquid storage gap 23 can be formed at the end of the rod body 20 far from the end cover portion 10, which helps to improve the sealing effect of the sealing plug 100.

[0041] Exemplarily, the rod body 20 is provided with a draft slope. The draft slope helps the sealing plug 100 to be demolded and can also improve the smoothness of insertion or extraction of the sealing plug 100 during the use of the sealing plug 100. Exemplarily, the rod body 20 can be set as a cone.
