[0035] Furthermore, the housing 1 has good durability and aesthetics to meet the wear and impact caused by daily use, as well as the user's demand for the appearance of the atomizer device. The atomizer device also includes a bottom cover 7. The housing 1 and the bottom cover 7 are connected to form a shell structure of the atomizer device, which is used to protect and fix the components disposed within the housing 1 and the bottom cover 7.

[0036] Reference Figure 4As shown, the housing 1 is provided with a mounting cavity 11 and at least one plug 12. The plug 12 is part of the housing 1 and is assembled along with the housing 1 during assembly of the atomizer. The plug 12 can be integrally formed with the housing 1, which can save production costs and process steps. The plug 12 can also be fixedly connected to the housing 1 by welding or other methods. The present embodiment of the present application does not specifically limit the method of connection between the plug 12 and the housing 1; however, the plug 12 must be assembled together with the housing 1.

[0037] Liquid storage tank 2 houses an oil tank for storing aerosolized substrate. The aerosolized substrate within the oil tank is heated by atomizing assembly 62 located within the oil tank and atomized into an aerosol. Liquid storage tank 2 is provided with at least one liquid injection port 21. After the atomizing device is assembled, the aerosolized substrate is injected into the oil tank through liquid injection port 21.

[0038] The atomizing device of the embodiment of the present application comprises a housing 1 provided with a mounting cavity 11 and at least one plug 12; a liquid storage tank 2 for storing atomized substrate, and provided with at least one liquid injection hole 21 communicating with the interior; the liquid storage tank is mounted within the mounting cavity 11, and the plug 12 cooperates with the liquid injection hole 21 to seal the liquid injection hole 21. The atomizing device uses the plug 12 on the housing 1 to seal the liquid injection hole 21.

[0039] Moreover, the use of the plug 12 on the housing 1 to seal the liquid injection hole 21 also avoids the use of a silicone seal to seal the liquid injection hole 21.

[0060] In the embodiment of the present application, the provision of the guide protrusion 13 can limit the positional relationship between the liquid storage bin 2 and the housing 1 , and the guide protrusion 13 abuts against the liquid storage bin 2 .

[0063] In an embodiment of the present application, the side wall of the liquid storage element 4 is provided with a ventilation groove 41 extending in the height direction. The ventilation groove 41 can increase the rate at which gas enters the liquid storage element 4, thereby avoiding the consumption of the atomized matrix in the liquid storage element 4 to generate negative pressure, which affects the normal use of the atomization device.

The nozzle decorative piece 31 and the first condensation member 32 are sequentially installed at the inlet end of the nozzle 3. The first condensation member 32 and the nozzle decorative piece 31 are stacked. Then, the inlet end of the nozzle 3 is inserted into the mounting hole 14 of the housing 1. The nozzle 3 and the mounting hole 14 are interference fit to form the main components of the atomization device.

[0075] The atomizing device of the embodiment of the present application uses the plug 12 on the shell 1 to block the liquid injection hole 21 of the liquid storage tank 2 to achieve sealing of the liquid injection hole 21; the upper cover and the base 26 are connected by an interference fit to achieve a sealing effect; and the suction nozzle 3 and the mounting hole 14 of the shell 1 are also connected by an interference fit to achieve a sealing effect; the above structure of the atomizing device can reduce the assembly process and the components in the atomizing device, reduce the cost of the atomizing device, and the atomizing device can be better adapted to automated production.
