[0031] Please refer to Figure 1-Figure 8, an atomizer comprises: an atomizing core 100, wherein a liquid storage tank 200 is disposed outside the atomizing core 100; a top seat assembly 400, connected to one end of the liquid storage tank 200, and an exhaust channel is disposed on the top seat assembly 400; a liquid injection assembly 300, arranged at one end of the liquid storage tank 200 facing away from the top seat assembly 400, and an injection channel 301 communicating with the liquid storage tank 200 is disposed inside the liquid injection assembly 300; a return liquid inlet and exhaust assembly, used for opening and closing the exhaust channel and the liquid injection channel 301, and the return liquid inlet and exhaust assembly is configured so that when the liquid thrust in the injection channel 301 is greater than the thrust of the return liquid inlet and exhaust assembly, the injection channel 301 is communicated with the liquid storage tank 200, and the liquid storage tank 200 is communicated with the outside world through the exhaust channel, and when the liquid thrust in the injection channel 301 is less than the thrust of the return liquid inlet and exhaust assembly, the return liquid inlet and exhaust assembly returns to close the exhaust channel and the liquid injection channel 301.

[0032] When liquid is being injected, the liquid pressure pushes the return liquid inlet and exhaust assembly to make the injection channel 301 and the exhaust channel connected to the liquid storage tank 200; after the injection is completed, the return liquid inlet and exhaust assembly returns to its position, and the return liquid inlet and exhaust assembly closes the exhaust channel and the injection channel 301; that is, automatic sealing can be completed after the injection is completed, which can avoid leakage, avoid waste, ensure cleanliness, and improve convenience and user experience.

[0033] Please refer to Figure 1-Figure 4 and Figure 8 The top seat assembly 400 includes a rotary cover 410 and a top seat 420. The top seat 420 is provided with a liquid injection hole 422. The rotary cover 410 is provided with an adjustment hole 412. The exhaust passage includes an exhaust hole 411 provided on the rotary cover 410 and an exhaust cavity 421 provided in the top seat 420. The rotary cover 410 adjusts the connection between the exhaust hole 411 and the exhaust cavity 421 and the connection between the adjustment hole 412 and the liquid injection hole 422 by rotation. The liquid injection hole 422 and the adjustment hole 412 can be provided to perform top liquid injection as needed; due to the function of the return liquid inlet and exhaust assembly, the exhaust cavity 421 can be closed to avoid leakage from the exhaust hole 411.

[0034] In particular, when the exhaust hole 411 is connected to the exhaust cavity 421, the rotary cover 410 closes the injection hole 422. That is, the exhaust hole 411 can be kept connected with the exhaust cavity 421 to prevent leakage from the adjustment hole 412. In particular, a radially opening slot 423 is provided on the top seat 420, and a protrusion 413 adapted to the slot 423 is provided on the rotary cover 410. The rotation is limited by the cooperation between the slot 423 and the protrusion 413. In particular, when the protrusion 413 rotates to one end of the slot 423, the adjustment hole 412 is connected with the injection hole 422, and when the protrusion 413 rotates to the other end of the slot 423, the exhaust hole 411 is connected with the exhaust cavity 421.

[0035] Please refer to Figure 1-Figure 4A sealing gasket 430 is provided between the screw cap 410 and the top seat 420. The sealing gasket 430 can improve the sealing performance and prevent liquid leakage.

[0036] Please refer to Figure 1-Figure 2 and Figure 6 The return liquid inlet and exhaust assembly includes an elastic member and a sealing member. A connecting port connected to the liquid storage tank 200 is provided in the liquid injection channel 301. One end of the sealing member extends into the liquid injection channel 301 and is provided with a baffle 511 for blocking the connecting port. The elastic member abuts against the sealing member. It can be understood that when the liquid in the liquid injection channel 301 pushes the sealing member, the elastic member has a restoring force. After the liquid injection stops, the sealing member closes the liquid injection channel 301 and the exhaust channel under the push of the restoring force of the elastic member.

[0037] Please refer to Figure 6 A sealing ring 512 is provided in the exhaust cavity 421, and the sealing ring 512 is sleeved on the sealing member, and the baffle 511 abuts against the sealing ring 512 to seal the communication port. The sealing member abuts against the sealing ring 512 to seal the exhaust cavity 421, which can improve the sealing performance and prevent liquid from leaking from the exhaust cavity 421.

[0038] As one embodiment of the present invention, the sealing member includes a columnar body 510, on which a baffle plate 511 is disposed to abut against and seal the communication port. The baffle plate 511 seals the communication port while the columnar body 510 seals the injection channel 301. In particular, as another embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 5-Figure 7 The sealing member includes a column 510 and a sphere 520, a baffle 511 is arranged on the column 510, the sphere 520 is arranged between the column 510 and the liquid outlet of the liquid injection component 300, and a sleeve 540 is arranged on the outer sleeve of the sphere 520, and the inner diameter of the sleeve 540 is larger than the outer diameter of the sphere 520. The sphere 520 can better seal the liquid injection channel 301. The sleeve 540 is arranged to prevent the sphere 520 from detaching, and ensure that the sphere 520 can close the liquid injection channel 301 after the liquid injection is completed. It can be understood that there is a gap between the baffle 511 and the peripheral wall of the exhaust cavity 421, so that the exhaust hole 411, the exhaust cavity 421 and the liquid storage tank 200 are connected after the baffle 511 is away from the connecting port.

[0039] In particular, a flexible pad is provided at the liquid outlet 312 of the liquid injection component 300. The flexible pad is directly glued or integrally formed and fixed on the liquid injection component 300. The flexible pad is provided to improve the sealing performance. It can be understood that the sealing pad 430, the sealing ring 512 and the flexible pad are generally made of materials such as silicone and rubber, and other materials can also be used as needed.

Simply, the liquid injection channel 301 can also not pass through the positive electrode 350, and a connecting tube can be extended from the base 330 to the back of the base 320, that is, the liquid injection channel 301 is arranged in the base 330, the base 320 and the bin seat 310. Simply, the base 330 is provided with an air regulating ring 340 on the outer cover to adjust the airflow in the flue of the atomization core 100. In particular, the liquid outlet of the injection channel 301 in contact with the ball 520 is funnel-shaped, that is, the liquid outlet 312 of the liquid guide tube 311 is a funnel groove, which is generally inclined and can also be designed to be an arc surface as required.

[0042] The sealing connection in the present invention generally adopts silica gel or rubber, and other sealing materials can also be used for simplicity. The shape of the sealing material is set according to the needs, and is generally annular.
