BACKGROUND

A nasal irrigator is used to clean the nasal cavity. It usually employs a certain pressure (such as an airbag type nasal irrigator, gravity such as a simple bottle-can type, or mechanical pressure such as electric type) to send a cleaning liquid (such as saline) into nostrils, which is beneficial for the cleaning liquid to clean the nostrils. Through the above path, with the help of the bactericidal effect of the saline itself and the impact of water flow, accumulated pathogens and pollutants in the nasal cavity are discharged. In this way, a normal physiological environment of the nasal cavity is restored, a self-detoxification function of the nasal cavity is restored, and the purpose of protecting the nasal cavity is achieved.
