In daily life, hair washing has become personal hygiene habit of people, and many people need to wash hair once every day for about half a month, so that the hair washing work is finished at home by many people, and also, a few people finish hair washing work at barbershops. However, in a hair-dressing shop, a person specially responsible for hair-washing in the hair-dressing shop usually washes hair once before hair dressing, and sometimes hair is dressed once again to clean short hair stubbles adhered to the hair. Therefore, the workload of hair washing in the barbershop is large, the hair washing expenditure (staff wages) of the barbershop is increased, and the health problems of hand peeling, red swelling and the like caused by long-term contact of the hair washing staff with the shampoo. Manual hair washing makes the hair washing personnel closely contact with the customers, and diseases are easily transmitted by breathing, sneezing, scratching the scalp of the customers by nails, and the like. At present, although patent documents describe automatic hair washing machines, most of the automatic hair washing machines have complex structures, various parts and high production cost, and the automatic hair washing machines are difficult to clean and maintain.
