Background
The atomizing cup is a device which atomizes and sprays liquid, and liquid particles are uniformly suspended in the air. The medical instrument has wide application in modern life, and can be widely applied to medical instruments for treating respiratory diseases.
At present, the atomizing cup generally sold in the market is mainly a compression atomizer, and is widely applied to the medical field. The air compression type atomizing cup obtains high-speed gas through compressed air, negative pressure generated along with the high-speed gas can attract liquid to flow in, and then two phases are mixed and collide with each other to generate high-speed spraying finally.
Although the development of the atomization technology in China is mature day by day, most of the existing atomization cups in the market still face the following problems: (1) the particles atomized by the atomizing cup are large and uneven and are easy to collide and combine, so that the use risk exists for patients with respiratory diseases; (2) the atomization rate of the atomizing cup cannot be adjusted. If the atomization rate is too fast, the atomizing agent has obvious impact on the mouth and the nose of a human body; if the atomization rate is too fast, the atomization method consumes long time, consumes more energy and has low atomization efficiency. Therefore, the existing atomizing cup has the defects of large atomizing particles and low atomizing efficiency, and has very poor effect on treating respiratory diseases, particularly lower respiratory diseases.

The invention has the beneficial effects that: when high-speed high-pressure gas enters from the gas inlet pipe unit and passes through the energy-saving ring, negative pressure is formed in the water containing cavity pipe body, so that liquid is automatically sucked into the water containing cavity pipe body through the rear end gas inlet pipe, is further smashed into small liquid drops by the high-speed gas, and is discharged from the outlet pipe together under the wrapping of the gas. Because the first crushing of the rear end air inlet pipe is carried out and the second crushing of the cup wall at the outlet of the rear end air inlet pipe is carried out, the liquid drop crushing effect is better than that of a common atomizing cup, and the liquid drop particles after crushing are smaller. Meanwhile, the size of a fan-shaped opening formed by the first semicircular baffle plate and the second semicircular baffle plate can be adjusted. The size of the fan-shaped opening can influence the negative pressure of the water containing cavity. When the fan-shaped opening is opened, the negative pressure of the water containing cavity can suck air to the upper part of the air inlet pipe bracket, so that the water absorption to the lower part can be weakened; when the fan-shaped opening is closed, the negative pressure of the water containing cavity can be completely acted on the lower water suction pipe at the lower part of the air inlet pipe bracket, and the water absorption is strongest at the moment. Therefore, the water suction speed can be adjusted by adjusting the size of the fan-shaped opening. Can produce smaller atomized particles than the existing atomizing cup on the market, and the atomizing speed can be adjusted.
