When the atomizer 100 is not in use, the isolating rod 30 is inserted into and penetrates through the atomizing assembly 20, so that the atomizing assembly 20 is prevented from being contacted with air, and oxidative deterioration of the atomizing assembly 20 and the aerosol generating substrate due to long-term contact with air is avoided. The user pulls the nebulizer 100 after pulling the spacer from the nebulizing assembly 20. The nebulizing assembly 20 is capable of heating and nebulizing the aerosol-generating substrate stored in the reservoir assembly 10 into an aerosol under the electrical drive of the power supply assembly.

Referring to fig. 2 and 3, the liquid storage assembly 10 includes a housing 11, a base 12 mounted at one end of the housing 11, and a first seal 13 disposed over the base 12. The housing 11 and the base 12 together form a liquid storage chamber 113 for storing aerosol-generating substrate, a suction nozzle 111 is arranged at one end of the housing 11 facing away from the base 12, and an air outlet hole 1111 is arranged at the suction nozzle 111. The air outlet 1111 is provided with a connection pipe 112 at one side close to the liquid storage chamber 113, and the lower end of the connection pipe 112 is connected with the atomizing assembly 20. The connection pipe 112 is communicated with the atomization assembly, and aerosol generated by the atomization assembly 20 can sequentially leave the atomizer 100 through the connection pipe 112 and the air outlet 1111 under the driving of gas.

Referring to fig. 2, the base 12 is provided with an air inlet 123 communicating with the atomizing assembly 20, and one side of the air inlet 123 is provided with a liquid injection hole 121. The liquid injection hole 121 is communicated with the liquid storage cavity 113, a liquid injection plug 122 is installed in the liquid injection hole 121 to prevent leakage of aerosol generating substrate in the liquid storage cavity 113, and a user can supplement the aerosol generating substrate in the liquid storage cavity 113 through the liquid injection hole 121. In this embodiment, the connection between the base 12 and the housing 11 is a clamping connection, and in other embodiments, the connection between the base 12 and the housing 11 may be a screw connection or an adhesive connection.

Referring to fig. 2, the first sealing member 13 is provided with a mounting hole 131 for mounting the atomizing assembly 20, and a through hole 132 communicating with the air inlet hole 123 is provided at the bottom of the mounting hole 131. After the user inhales the nebulizer 100, gas may enter the nebulizing assembly 20 from the inlet aperture 123 through the through-hole 132. The first seal 13 is located at the bottom of the reservoir 113 with its side wall in sealing contact with the inner wall of the housing 11 to avoid leakage of the aerosol-generating substrate. In the present embodiment, the liquid filling plug 122 penetrates the first sealing member 13 after being inserted into the liquid filling hole 121, and the liquid filling plug 122 is in sealing contact with the first sealing member 13 to further enhance the sealing performance. In some embodiments, the first seal 13 may be a silicone or rubber member.

Referring to fig. 2 and 3, the atomizing assembly 20 includes an atomizing outer tube 21, an atomizing inner tube 22 sleeved inside the atomizing outer tube 21, and an atomizing core 23 provided inside the atomizing inner tube 22.

The aerosol-generating substrate in the liquid storage chamber 113 can enter the liquid guide 213 from the first liquid inlet aperture 211, then be guided to the atomizing core 23 via the liquid guide 213, and finally be heated and atomized into an aerosol by the atomizing core 23. During this process, the aerosol-generating substrate within the reservoir 113 builds up a negative pressure within the reservoir 113 as it is continually consumed. Because the auxiliary cavity 212 is communicated with the through hole 132, air entering the auxiliary cavity 212 from the through hole 132 sequentially passes through the micro air passage in the liquid guide piece 213 and the first liquid inlet hole 211 to enter the liquid storage cavity 113 under the action of atmospheric pressure, so that the pressure in the liquid storage cavity 113 is raised and the negative pressure is reduced, and aerosol generating substrate in the liquid storage cavity 113 can stably enter the atomizing core 23 through the first liquid inlet hole 211 and the liquid guide piece 213, and thus the dynamic circulation is realized. During this cycle, the process of directing the aerosol-generating substrate by the liquid guide 213 towards the atomizing core 23 and the process of replenishing the liquid storage chamber 113 with air may be performed simultaneously to maintain a relatively stable pressure within the liquid storage chamber 113, so that the atomizing core 23 is always supplied with a stable aerosol-generating substrate, thereby reducing the chance of dry burning of the atomizing core 23. The liquid guide 213 may be porous fiber, porous ceramic, porous cotton or sponge.

As shown in fig. 2, the upper end of the atomizing inner tube 22 is provided with a connecting portion 221, and a second liquid inlet 223 is formed on the sidewall thereof.

The aerosol-generating substrate drawn by the liquid guide 213 enters the atomizing core 23 through the second liquid inlet 223, and is subsequently heated and atomized into an aerosol.

As shown in fig. 2, the atomizing core 23 includes a heat generating member 231 electrically connected to the power supply assembly, a liquid absorbing member 232 connected to the heat generating member 231, and an atomizing chamber 233 extending axially along the atomizing inner tube 22 is formed inside the heat generating member 231, and the atomizing chamber 233 communicates with the through hole 132 and the connection tube 112. In this embodiment, the liquid absorbing member 232 is a hollow tubular structure, which is sleeved in the atomizing inner tube 22.

The user sucks the atomizer 100, and air sequentially enters the atomizing chamber 233 through the air inlet hole 123 and the through hole 132, and then enters the user's mouth with the aerosol through the connection pipe 112 and the air outlet hole 1111. In some embodiments, the wicking 232 may be porous fiber, porous ceramic, porous cotton, or sponge.

Referring to fig. 2 and 3, the spacer 30 includes a body 31, a sealing ring 33 sleeved on the body 31, and a closure member 32 connected to one end of the body 31.

The end of the sealing member 32 far away from the main body 31 is further provided with a tapered guiding portion 321, so as to avoid the interference between the sealing member 32 and the heating member 231 during the process of inserting and penetrating the isolating rod 30 into the atomizing assembly 20, and the heating member 231 is damaged and fails. When the isolating rod 30 is inserted into the atomizer 100, the sealing ring 33 can be in sealing fit with the connecting pipe 112 to prevent air from entering the atomizing cavity 233 through the air outlet 1111; the guide 321 can cooperate with the air inlet aperture 123 to prevent air from entering the nebulization chamber 233 from the air inlet aperture 123. In the present embodiment, the through hole 132 of the first sealing member 13 is further provided with a fitting portion 133 surrounding the through hole 132, and the fitting portion 133 is in sealing contact with the closure member 32 to enhance the sealing effect on the air intake hole 123.
