## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation-in-part of application Ser. No. 17/902,260 filed on Sep. 2, 2022, the content of which is incorporated herein by reference.


TECHNICAL FIELD
The present application relates to the technology in the field of atomizers, in particular to an atomizer with an intelligent control digital display function.
BACKGROUND
The atomizer is mainly used to treat various upper and lower respiratory diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases that occur in the trachea, bronchi, alveoli, and chest. Aerosol inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases. The liquid medicine is atomized into tiny particles by the atomizing inhaler, and the medicine enters the respiratory tract and lungs by breathing inhalation, so as to achieve the purpose of painless, rapid and effective treatment.
Compressed air atomizer is a kind of atomizer, which is also called jet atomization. According to the principle of Venturi injection, compressed air is used to form a high-speed airflow through a small nozzle. The generated negative pressure drives the liquid or other fluids to be sprayed onto the barrier together, and splashes around under the high-speed impact, so that the droplets become mist-like particles and are ejected from the air outlet.
The current air compression atomizer generally does not have a digital display function, which brings inconvenience to use, and has poor heat dissipation effect and short product life. Therefore, it is necessary to improve the current air compression atomizer.
