Description
Technical Field

[0002] A nebulizer is an electronic device that atomizes the test solution into tiny particles and then outputs them together with the air. The human body enters the respiratory tract and lungs through breathing. When used medically, the nebulizer can be used to treat upper and lower respiratory system diseases such as colds, bronchitis, asthma, etc. Compared with traditional injections and medications, the nebulizer directly acts on the diseased part for treatment, which has the advantages of painless, rapid and effective treatment. You can also breathe some fresh air through the nebulizer at ordinary times.
[0003] Respiratory diseases have been on the rise in recent years, especially among children, who need to go in and out of hospitals frequently during the cold season. The large number of patients and long waiting times in hospitals increase the risk of cross infection, so some manufacturers have launched home-use nebulizers.

Users often forget the usage time when using it at home, so it is necessary to set a timing function on the nebulizer to accurately mark the nebulizer usage time. Utility Model Content
