Problems solved by technology

The noise value of the currently used medical nebulizer is about 60 decibels. The noise of the medical nebulizer is mainly due to the sudden change of the air flow resistance when the gas flows into the air cavity from the air inlet of the oil-free piston compressor. The layer is destroyed, resulting in vibration; the frequency of the above vibration has a certain overlap with the natural frequency of the air cavity under the existing internal structure, which causes resonance and increases the vibration of the sound source

Abstract

The invention provides an oil-free piston compressor of a medical vaporizer. The oil-free piston compressor comprises a crankshaft, an air cylinder, a piston, a connection rod, an air cavity and an air valve, wherein the crankshaft and the air cylinder are connected with an output shaft of a motor, the piston is mounted in the air cylinder in an inserted manner, the crankshaft and the piston are connected via the connection rod, the air cavity is fixed on an end portion of the air cylinder, the air valve is arranged between the air cavity and the air cylinder, the air cylinder is provided with an air inlet and an air outlet, and the air inlet comprises an extension portion fixed inside the air cavity. The air inlet is provided with the extension portion in the air cavity, overlap between vibration generated due to airflow flows into the air cavity from the air inlet and intrinsic frequency of the oil-free piston compressor, sound resonance phenomenon is reduced, and noise is greatly lowered.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an oil-free piston compressor for a medical nebulizer. Background technique [0002] Medical nebulizers are 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 cavity. Nebulization inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases. The nebulizer inhaler is used to atomize the liquid medicine into tiny particles, and the medicine enters the respiratory tract and lung deposition through inhalation, so as to achieve painless , The purpose of rapid and effective treatment. [0003] There are two main atomization principles currently used, one is an ultrasonic nebulizer, and the other is a compression nebulizer. The nebulizer of the ultrason...
