Ear-washing machine and control method thereof

Abstract

The invention discloses an ear-washing machine and a control method thereof. A cleaning device comprises a casing and a cleaning part. The casing is divided into a sewage recycling cavity, a water storage cavity and an installation cavity by partition plates. A sewage recycling pump is arranged in the sewage recycling cavity, a water outlet pump is disposed in the water storage cavity, and a constant temperature heater is arranged between the water storage cavity and the water outlet pump. A controller for controlling the sewage recycling pump, the water outlet pump and the constant temperature heater is arranged in the installation cavity. The cleaning part comprises a nozzle, a handle and a water-conveying hose. The nozzle is detachably arranged at the front end of the handle, one end of the water-conveying hose penetrates the handle to be connected with the nozzle, and the other end of the water-conveying hose penetrates the casing to be detachably connected with the sewage recycling pump and the water outlet pump. The ear-washing machine can accurately control water pressure, jet velocity and water outlet temperature, a comfortable clean water flow is generated, and the ear-washing machine has a wastewater collecting function and is practical and portable.

Description

technical field [0001] The invention relates to the technical field of personal cleaning and care products, in particular to an earphone washing device and a control method thereof. Background technique [0002] The external auditory canal is a curved duct from the outer ear door to the tympanic membrane, with a total length of about 2.1 to 2.5 cm. The secretion produced by the glands in the cartilage skin of the external auditory canal is earwax. The existence of human earwax affects hearing. Using unclean ear picks to dig earwax is easy to bring germs into the external auditory canal, causing diseases of the external auditory canal. The main manifestations are various inflammations. Symptoms include ear itching, discomfort in the ear, congestion, swelling, and watery discharge. Hearing can be severely affected when the inflammation is severe or when the ear canal is blocked by secretions. Due to the small size of the ear canal and the sensitivity of the tympanic membrane...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing ear cleaning devices on the market have the following defects: 1. It is inconvenient to use for water supply by connecting to tap water, and cannot realize portable operation; 2. Due to the passive water supply of tap water, it is impossible to accurately control the water pressure of the outlet water, and the user experience Poor; 3. Wastewater is collected by natural gravity, the collection efficiency is low and the effect is poor; 4. The output water temperature is not constant
