The negative pressure component is used to create a negative pressure environment for the first cavity, is connected to the first cavity, and is used to put the first cavity in a negative pressure state.

[0008] By setting a negative pressure component in the atomizer, a low-pressure and low-temperature environment can be formed in the first cavity of the atomizer, thereby improving the ultrasonic atomization effect. In a low-temperature and low-pressure environment, the mist particles formed after ultrasonic atomization can better meet medical needs, further improve the atomization treatment effect, and reduce the treatment cycle.

[0009] In addition, the atomizing device in the above technical solution provided by the present invention may also have the following additional technical features:

After ultrasonic atomization, the medicine is dispersed into tiny mist particles. The tiny mist particles enter from one end of the mist outlet pipe and are sprayed out from the other end of the mist outlet pipe to directly act on the local area for local treatment. The mist outlet pipe is provided with a regulating valve. By controlling the opening of the regulating valve, the mist output can be controlled.

[0020] In this technical solution, the negative pressure component includes a vacuum pump and a controller. The vacuum pump is connected to the first cavity. During operation, the vacuum pump can pump out the air in the first cavity to form a vacuum environment in the first cavity. While pumping out the air in the first cavity, the vacuum pump can form a low-pressure and low-temperature working environment in the first cavity to improve the ultrasonic atomization effect. The controller is connected to the vacuum pump and the ultrasonic atomization component at the same time, so as to realize simultaneous control of the ultrasonic atomization component and the vacuum pump.

[0021] In any of the above technical solutions, the vacuum pump is a miniature vacuum pump with a power less than or equal to 5W.

[0022] In this technical solution, the vacuum pump is a miniature vacuum pump with a power less than or equal to 5W. The miniature vacuum pump only occupies a very small space in the atomization device, and can also meet the demand for vacuuming the first cavity.

[0030] Before ultrasonic atomization, the first cavity is evacuated by a vacuum pump to ensure a low-pressure and low-temperature environment in the first cavity. In a low-temperature environment, the ultrasonic atomization effect of the drug is better.

[0031] In the above technical solution, the control method of the nebulizer device also includes: obtaining the atomization concentration of the drug in the first cavity; adjusting the operating parameters of the ultrasonic atomization component according to the atomization concentration; and controlling the atomization pipe of the nebulizer device to be turned on to emit mist based on the atomization concentration reaching the target concentration.

[0032] In this technical solution, after the ultrasonic nebulizer component is started, the drug atomization concentration in the atomization chamber in the first cavity is obtained through the detection component. When the drug atomization concentration is insufficient, the atomization efficiency is improved by adjusting the operating parameters of the ultrasonic nebulizer component, thereby increasing the atomization concentration; on the contrary, when the drug atomization concentration is too high, the atomization efficiency is reduced by adjusting the operating parameters of the ultrasonic nebulizer component, thereby reducing the amount of mist output; based on the atomization concentration reaching the target concentration, the mist output pipe in the atomizer device is turned on to emit mist, and the mist output is controlled by controlling the opening of the regulating valve to provide local treatment to the user.
