[0034] The present application embodiment provides a liquid injection device 1, please refer to Figures 1 to 3The injection device 1 can inject the atomized matrix 6 into the atomizer 5. The injection device 1 includes a cavity 10 and an injection assembly 20. The cavity 10 is provided with a first inner cavity 101, and the first inner cavity 101 is used to store the atomized matrix 6; the injection assembly 20 includes a fixed part 210 and a movable part 220. The fixed part 210 is fixedly connected to the cavity 10, and the movable part 220 is movably connected to the side of the fixed part 210 away from the cavity 10. A second inner cavity 201 is formed between the movable part 220 and the fixed part 210. The fixed part 210 is provided with a first conduit 211, and the first conduit 211 is used to connect the first inner cavity 101 and the atomizer 5. The fixed part 210 is also provided with a second conduit 201. A gas channel 2131 is provided, and the gas channel 2131 is used to connect the first inner cavity 101 and the second inner cavity 201; the movable member 220 can reciprocate between the first position and the second position. When the movable member 220 is located at the first position, the gas channel 2131 does not connect the first inner cavity 101 and the second inner cavity 201; when the movable member 220 is located at the second position, the gas channel 2131 connects the first inner cavity 101 and the second inner cavity 201 to press the gas in the second inner cavity 201 into the first inner cavity 101 through the gas channel 2131, and then press the atomized substrate 6 in the first inner cavity 101 into the atomizer 5 through the first conduit 211. When the movable member 220 is located at the first position, the volume of the second inner cavity 201 is greater than the volume of the second inner cavity 201 when the movable member 220 is located at the second position.

[0035] In some embodiments, when the movable member 220 is located at the first position, the movable member 220 is away from the first inner cavity 101, and when the movable member 220 is located at the second position, the movable member 220 is close to the first inner cavity 101. The movable member 220 can move toward the first inner cavity 101 under the action of an external force, and move from the first position to the second position, so that the volume of the second inner cavity 201 is reduced, so that the gas in the second inner cavity 201 is pressed into the first inner cavity 101 through the gas channel 2131, and then the atomized substrate 6 in the first inner cavity 101 is pressed into the atomizer 5 through the first conduit 211.

[0036] When the liquid injection device 1 performs liquid injection operation on the atomizer 5 installed on the liquid injection device 1, the movable part 220 moves toward the first inner cavity 101 under the action of external force, compressing the space of the second inner cavity 201, so that the gas in the second inner cavity 201 moves to the first inner cavity 101, thereby increasing the air pressure in the first inner cavity 101, and the air pressure in the atomizer 5 is atmospheric pressure. Under the action of the air pressure difference, the atomized matrix 6 in the first inner cavity 101 is pressed into the atomizer 5 through the first conduit 211. The user only needs to apply pressure on the movable part 220 to realize the liquid injection operation of the liquid injection device 1, which is simple and convenient to operate and is conducive to improving the liquid injection efficiency.

[0037] In some embodiments, one end of the first conduit 211 is located in the first inner cavity 101 and is disposed close to the bottom wall 120 of the cavity 10, so that the atomized substrate 6 at the bottom of the first inner cavity 101 can enter the first conduit 211. One end of the first conduit 211 facing the bottom wall 120 can be pointed to prevent the first conduit 211 from being closed due to abutment with the bottom wall 120.

[0038] In some embodiments, when the movable part 220 reciprocates between the first position and the second position, the gas channel 2131 can remain connected to the first inner cavity 101 and the second inner cavity 201, and the distance between the second inner cavity 201 and the bottom wall 120 can be greater than or equal to the height of the first inner cavity 101 to avoid the atomized matrix 6 from sinking into the second inner cavity 201 when the first inner cavity 101 is fully stored with the atomized matrix 6.

[0039] In some embodiments, the fixing member 210 is fixedly connected with a second conduit 212, and the second conduit 212 is located at one end of the gas channel 2131 away from the second inner cavity 201. The second conduit 212 can communicate the first inner cavity 101 with the second inner cavity 201 through the gas channel 2131. In some other implementations, the second conduit 212 can also pass through the gas channel 2131, so that one end of the second conduit 212 is located in the first inner cavity 101, and the other end is located in the second inner cavity 201.

[0040] In some embodiments, a third conduit 221 is provided on the movable part 220, one end of the third conduit 221 is connected to the second inner cavity 201, and the other end is arranged toward the second conduit 212. When the movable part 220 is in the first position, the second conduit 212 and the third conduit 221 are not connected; when the movable part 220 is in the second position, at least part of the structure of the third conduit 221 is inserted into the second conduit 212, and the second inner cavity 201 is connected to the first inner cavity 101 through the second conduit 212 and the third conduit 221.

[0041] In some embodiments, when the movable member 220 moves toward the first inner cavity 101 under the action of external force, the third conduit 221 penetrates the gas channel 2131 and is inserted into the second conduit 212 , and the second inner cavity 201 is connected to the first inner cavity 101 through the second conduit 212 and the third conduit 221 .

[0042] In some embodiments, one end of the second conduit 212 may be located in the first inner cavity 101 and disposed close to the bottom wall 120 of the cavity 10, and the second conduit 212 has a certain length, so that during the movement of the movable member 220 toward the first inner cavity 101, the end of the third conduit 221 toward the bottom wall 120 cannot be exposed from the second conduit 212. When the gas in the second inner cavity 201 enters the first inner cavity 101 through the second conduit 212, an air column may be formed in the second conduit 212 to isolate the third conduit 221 from the atomized substrate 6.

[0043] In some embodiments, a first seal 2121 is provided at one end of the second conduit 212 facing the third conduit 221, and the first seal 2121 can seal the second conduit 212. A first puncture end 2211 is provided at one end of the third conduit 221 facing the second conduit 212. When the movable member 220 is located at the second position, the first puncture end 2211 pierces the first seal 2121 to connect the second conduit 212 and the third conduit 221. The provision of the first seal 2121 can separate the second inner cavity 201 from the first inner cavity 101 when the injection device 1 is not performing the injection operation, so as to prevent the injection device 1 from shaking during transportation or movement, and allow the atomized matrix 6 in the first inner cavity 101 to flow into the second inner cavity 201. Due to the sealing effect of the first sealing member 2121, the distance between the second inner cavity 201 and the bottom wall 120 can be smaller than the height of the first inner cavity 101. Even if the atomized substrate 6 is submerged in the first end 213, the atomized substrate 6 cannot flow into the second inner cavity 201 when the gas channel 2131 is sealed by the first sealing member 2121. The first piercing end 2211 can be sharp to facilitate piercing the first sealing member 2121.

[0044] In some embodiments, the material of the first sealing member 2121 may be a silicone material, and in other embodiments, the material of the first sealing member 2121 may also be a plastic or rubber material with elastic deformation capability. The first sealing member 2121 may be deformed when the first puncture end 2211 is inserted, and when the first puncture end 2211 is pulled away, the first sealing member 2121 may return to its original shape to automatically close and seal the second conduit 212.

[0045] In some embodiments, the number of the second conduits 212 may be one or more, and the number of the first sealing members 2121 and the third conduits 221 may be consistent with the number of the second conduits 212. The second conduits 212 may be arranged around the first conduits 211, and it is only necessary to open corresponding gas channels 2131 at positions corresponding to the second conduits 212 on the fixing member 210. Specifically, the number of the second conduits 212 may be 2, 3, 4, 6, etc.

[0046] In some embodiments, the fixing member 210 includes a first end 213 disposed near the first inner cavity 101, and a first groove 2101 is disposed on the side of the first end 213 facing away from the first inner cavity 101.

The first conduit 211 and the second conduit 212 are disposed on the first end 213, and the third conduit 221 is disposed on the second end 222.

[0047] In some embodiments, the gas channel 2131 can be opened on the first end 213 and located on the side of the first seal 2121 facing the second inner cavity 201. The third conduit 221 can be inserted into the gas channel 2131. The third conduit 221 can penetrate the gas channel 2131 and puncture the first seal 2121 under the action of external force.

[0048] In some embodiments, an elastic member 40 is disposed between the fixed member 210 and the movable member 220 , and the movable member 220 can move away from or approach the fixed member 210 under the elastic force of the elastic member 40 .

The second end 222 may move in the first groove 2101, and the second end 222 may move toward the first end 213 under the action of an external force to compress the volume of the second inner cavity 201. When the external force is removed, the second end 222 may move away from the first end 213 under the action of the elastic force of the elastic member 40 to restore the volume of the second inner cavity 201.

[0050] In some embodiments, the elastic member 40 may be a spring, and the material of the elastic member 40 may be a metal alloy or plastic having elastic deformation capability.
