The invention discloses a multifunctional nasal cavity cleaner. The cleaner is composed of control equipment, cleaning equipment and washing equipment. The cleaning equipment and the washing equipmentare both located on the control equipment. The control equipment is composed of a connecting rod. The connecting rod is externally provided with a charging hole and a controller. One end of the connecting rod is provided with an external water pipe connection port, and the connecting rod is internally equipped with a pressurization control valve, a motor, a power box and a water pipe. One end ofthe water pipe is sealingly connected with the pressurization control valve, and the other end of the water pipe is sealingly connected with the connecting port of the external water pipe. Through theaddition of the cleaning equipment, viscous substances inside the nasal cavity can be cleaned, and the nasal cavity can be cleaned more thoroughly by washing first and then cleaning. A control mainboard performs intelligent control over the washing equipment, and the cumbersome problems of traditional extrusion washing can be solved. At the same time, due to electronic control, the operation is more convenient and the water quantity of washing can be more precisely controlled.
