All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 2 , which shows an anti-leakage liquid sealing device for aromatherapy provided by an embodiment of the present invention, used to open or close the air outlet of an aromatherapy machine, including a seal 1, a reset element 2 and a pneumatic actuator 3. One end of the reset element 2 is connected to the seal 1, and the other end is fixed. The pneumatic actuator 3 abuts against the seal 1. The seal 1 covers the air outlet of the aromatherapy machine and has an open state and a sealed state. In the open state, the seal 1 moves upward under the action of the pneumatic actuator 3 to open the air outlet. In the sealed state, the pneumatic actuator 3 releases the action on the seal 1, and the reset element 2 closes the air outlet by the seal 1.

[0024] Specifically, the anti-leakage liquid sealing device for aromatherapy further includes an air cavity 9 and an air pump. The air cavity 9 is connected to the air pump, and the pneumatic actuator 3 is arranged at the outlet of the air cavity 9.

[0025] More specifically, the edge of the pneumatic actuator 3 covers and is fixed to the outer edge of the outlet of the air cavity 9. The middle part of the pneumatic actuator 3 protrudes downward.

The air chamber 9 includes a vertical cavity with a predetermined height and a horizontal cavity extending laterally. The vertical cavity and the horizontal cavity are in communication, and the vertical cavity and the pneumatic pusher 3 are coaxial.

[0034] In summary, this aromatherapy leak-proof liquid sealing device uses a pneumatic driving member 3 to cooperate with a sealing member 1 to switch the opening and sealing states of the sealing member 1, thereby realizing the opening or closing of the air outlet of the aromatherapy machine. When the air outlet is closed, the aerosol of the aromatherapy machine cannot flow to the fragrance-dispersing holes 8 through the peripheral gap, realizing the leak-proof liquid function. Moreover, the sealing member 1 is connected to a reset element 2. In the sealed state, the pneumatic driving member 3 releases its action on the sealing member 1, and the air outlet automatically closes under the action of the reset element 2. This structure enables the aromatherapy machine to achieve automatic leak-proof liquid without manual operation, making it convenient to use.
