The heating element can be in the form of a heating wire, a heating net or a heating needle, etc., and can be powered by the power supply component 200 to heat the aerosol to form a matrix. A core support can be provided at the bottom of the atomizer core. The core support is sealed with the inner wall of the liquid storage tank body 120 and the outer wall of the atomizer core, and can be surrounded by the liquid storage tank body 120 and the atomizer core to form a liquid storage cavity.

When in use, the user can inject liquid aerosols into the liquid storage cavity through the liquid injection port 125 to meet the use requirements.

[0051] A plug-in cavity may be provided at the top of the main housing 210 of the power supply component 200, and the upper end of the plug-in cavity is open, and the bottom of the atomizer component 100 may be inserted into the plug-in cavity and fixed. The fixing method between the atomizer component 100 and the main housing 210 is not limited, for example, at least one of magnetic fixing, snap fixing, interference fit fixing, and fastener fixing may be adopted.

[0052] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 4 The outer peripheral surface of the liquid storage tank body 120 is provided with an annular boss 122, and the lower end of the suction nozzle 110 is supported on the annular boss 122. The liquid storage tank body 120 includes a plug-in portion 124, which is located on the side of the annular boss 122 away from the suction nozzle 110. The plug-in portion 124 is used to be inserted into the plug-in cavity provided on the corresponding power supply component 200. The provision of the annular boss 122 can limit the depth of the atomization component 100 inserted into the power supply component 200, and can make the outer side surface of the electronic atomization device relatively flat to avoid the formation of obvious steps.

[0053] The specific structures of the above-mentioned atomizer core, core support and power supply assembly 200 can adopt existing structures in the relevant technology, and have no direct relationship with the technical solution that the present application hopes to protect, and will not be described in detail here. Next, the structure related to the injection of the liquid storage tank body 120 is specifically introduced.

[0054] Please refer to Figures 2 to 4 The liquid injection port 125 is disposed on the side wall of the liquid storage tank body 120. The liquid injection port 125 may be a through hole that penetrates the side wall of the liquid storage tank body 120. The shape of the through hole is not limited, such as rectangular, circular, elliptical, etc. The inner end of the through hole is connected to the liquid storage space in the liquid storage tank body 120, so that the liquid aerosol-forming matrix can be injected into the liquid storage tank body 120.

[0055] In order to prevent the aerosol-forming matrix in the liquid storage chamber from leaking out from the liquid injection port 125, the atomizer assembly 100 further includes a sealing plug 130, which is detachably connected to the liquid storage tank body 120 and can seal and open the liquid injection port 125. Figure 3 , Figure 4 and Figure 5 The sealing plug 130 includes a tank body connecting portion 131, a blocking portion 135 and a middle portion 136. The tank body connecting portion 131 is connected to the liquid storage tank body 120. The blocking portion 135 is used to block the liquid injection port 125. The middle portion 136 is connected between the tank body connecting portion 131 and the blocking portion 135. The middle portion 136 can be bent and deformed so that the blocking portion 135 can be separated from the liquid injection port 125. In order to facilitate the sealing between the sealing plug 130 and the liquid injection port 125, the sealing plug 130 can be integrally formed with an elastic material, such as silicone, rubber, polyurethane and the like. Of course, in a specific embodiment, the various parts of the sealing plug 130 can also be made separately and connected together.

[0056] In one embodiment, the tank body connection portion 131 includes a boss 132, and the liquid storage tank body 120 is provided with a plug hole 126, the boss 132 is inserted into the plug hole 126, and the portion of the boss 132 extending from the inner end of the plug hole 126 is provided with a radial protrusion 133, and the radial protrusion 133 is used to prevent the boss 132 from being separated from the plug hole 126. The sealing plug 130 is connected to the liquid storage tank body 120 by the boss 132, which is convenient to connect and does not occupy additional space outside the liquid storage tank body 120.

[0057] The plug hole 126 on the liquid storage tank body 120 can pass through the side wall of the liquid storage tank body 120, or avoid the liquid storage tank body 120. When the plug hole 126 passes through the side wall of the liquid storage tank body 120, the plug hole 126 will be connected to the liquid storage space in the liquid storage tank body 120. At this time, in order to prevent the leakage of the aerosol-forming matrix, the material of the protrusion 132 is an elastic material, and the protrusion 132 and the plug hole 126 are sealed. The plug hole 126 passes through the side wall of the liquid storage tank body 120, and the plug hole 126 can be conveniently formed without occupying additional space in the liquid storage tank body 120, and there is no need to set an additional isolation structure on the liquid storage tank body 120.

[0058] In the direction perpendicular to the axis of the boss 132, a tangent plane 134 is respectively provided on both sides of the radial protrusion 133, and the protrusion height at the tangent plane 134 is less than the protrusion height of the adjacent part. When the boss 132 is inserted into the plug hole 126, the tangent plane 134 can facilitate the deformation of the radial protrusion 133, thereby facilitating the connection between the tank body connecting part 131 and the liquid storage tank body 120. In addition, the radial protrusion 133 forms a conical surface on the outer peripheral surface of the corresponding part of the boss 132, which is convenient for guiding the boss 132 into the plug hole 126. In some other embodiments, the number of the tangent plane 134 can also be one, or more than three.

[0059] It should be noted that, in some other embodiments, the tank body connection part 131 may also be connected to the liquid storage tank body 120 using other structures. For example, an opening may be provided on the tank body connection part 131, and a convex column 132 may be provided on the outer wall of the liquid storage tank body 120, and the convex column 132 may be inserted into the opening on the tank body connection part 131 to achieve connection, and the opening may be a blind hole or a through hole.

[0060] When the sealing plug 130 is opened, in addition to the sealing portion 135 being subjected to a force acting toward the outside of the liquid injection port 125, the middle portion 136 is also subjected to a force and transmits the force to the tank body connecting portion 131. In order to prevent the tank body connecting portion 131 from being pulled off from the liquid storage tank body 120 due to excessive force when opening the sealing plug 130, the nozzle 110 has a limiting portion 115, which blocks the side of the tank body connecting portion 131 away from the liquid storage tank body 120, and is used to prevent the tank body connecting portion 131 from being separated from the liquid storage tank body 120.

[0061] In one embodiment, please refer to Figure 4 and Figure 6After the suction nozzle 110 is fixed to the liquid storage tank body 120, the shell side wall on the shell 111 of the suction nozzle 110 can block the tank body connecting part 131 of the sealing plug 130, and the corresponding part of the shell side wall forms a limiting part 115. In some other embodiments, according to the shape and fixing position of the suction nozzle 110, and the setting position of the tank body connecting part 131, the suction nozzle 110 can also be separately provided with a limiting part 115 to block the tank body connecting part, for example, a protruding part extending downward is provided on one circumferential side of the shell 111, and the protruding part is used to block the tank body connecting part.

[0062] In a specific embodiment, the nozzle 110 is provided with a plug avoidance opening 116, and the blocking portion 135 is exposed from the plug avoidance opening 116. The size of the plug avoidance opening 116 is larger than the corresponding size of the blocking portion 135 so that the blocking portion 135 can pass through the plug avoidance opening 116, which can facilitate the operation of the sealing plug 130. The above-mentioned limit portion 115 is located above the plug avoidance opening 116.

[0063] In one embodiment, the plug body avoidance opening 116 passes through the lower edge of the suction nozzle 110, and at least a portion of the sealing plug 130 is located in the plug body avoidance opening 116, so that the sealing plug 130 can be adapted to the situation where the sealing plug 130 protrudes from the surface of the liquid storage tank body 120, which is convenient for installing the suction nozzle 110 and convenient for operating the sealing plug 130 from the bottom side of the sealing plug 130 when opening the sealing plug 130. In some other embodiments, if the outer side surface of the sealing plug 130 is flush with the side surface of the liquid storage tank body 120 or is recessed into the side surface of the liquid storage tank body 120, the lower part of the plug body avoidance opening 116 can also be in a closed state.

[0064] In order to facilitate opening the sealing plug 130, in one embodiment, the sealing plug 130 includes an operating portion 137, which is connected to a side of the sealing portion 135 away from the middle portion 136. Along the axial direction of the liquid injection port 125, the size of the operating portion 137 is smaller than the size of the sealing portion 135, and the operating portion 137 overlaps the outer surface of the liquid storage tank body 120. When the sealing plug 130 needs to be opened, since the thickness of the operating portion 137 is small and easy to deform, the operating portion 137 of the sealing plug 130 can be tilted first, and then the operating portion 137 is used to drive the sealing portion 135 of the sealing plug 130 to open.

[0065] In the case where an annular boss 122 is provided on the outer circumferential surface of the liquid storage tank body 120, the suction nozzle 110 can be supported on the annular boss 122, and a notch 123 is provided on the side of the annular boss 122 close to the suction nozzle 110, at least part of the blocking portion 135 is located in the notch 123, and the operating portion 137 is located outside the annular boss 122 along the direction of the liquid injection port 125. The notch 123 on the boss can facilitate the provision of a larger liquid injection port 125, and more reasonably utilize the space on the atomizer assembly 100.

[0066] In one embodiment, a sink 127 is provided on the liquid storage tank body 120, and at least a portion of the tank body connecting portion 131 is embedded in the sink 127 along the depth direction of the sink 127. The provision of the sink 127 is conducive to bringing the suction nozzle 110 close to the liquid storage tank body 120, and the structure is more compact, which can reduce the space occupied by the suction nozzle 110. At the same time, the tank body connecting portion 131 can be limited by the sink 127 to prevent the tank body connecting portion 131 from rotating. The depth of the sink 127 can be equal to the thickness of the tank body connecting portion 131, or it can be less than the thickness of the tank body connecting portion 131, and it can also be greater than the thickness of the tank body connecting portion 131. In a specific embodiment, please refer to Figure 4 The side surface of the bin body connecting part 131 away from the liquid storage bin body 120 can be flush with the edge of the groove 127, and the inner wall of the limiting part 115 of the suction nozzle 110 is in contact with the outer peripheral surface of the liquid storage bin body 120, so that the space inside the suction nozzle 110 can be fully utilized, and the inner wall of the suction nozzle 110 can directly contact the bin body connecting part 131 to form a limit for the bin body connecting part 131.

[0067] When the electronic atomization device needs to be filled with an aerosol-forming matrix, such as when it is used for the first time or when the aerosol-forming matrix needs to be supplemented, the operating part 137 of the sealing plug 130 can be used to apply an opening force to the sealing plug 130, so that the sealing part 135 is separated from the liquid injection port 125, and then the sealing part 135 is further turned upward and passes through the plug body avoidance port 116 on the suction nozzle 110. After the liquid injection port 125 is fully exposed, liquid can be injected. Since the suction nozzle 110 can limit the storage body connecting part 131 of the sealing plug 130, the sealing plug 130 can be better prevented from being separated from the liquid storage tank body 120 during the process of opening the sealing plug 130, and the reliability is better.

[0069] The structure of the atomizer assembly is the same as the structure of the atomizer assembly 100 in any embodiment of the above-mentioned electronic atomizer device, and will not be described in detail here.
