Description

Technical Field

[0001] This utility model belongs to the technical field of hair washing machines, and more specifically, it relates to a sound insulation device and a hair washing machine. Background Technology

[0002] In modern hairdressing or daily life, washing hair is frequently necessary. To make the water more bubbly and easier to wash hair, a shampoo machine can generate bubbles in the water after mixing compressed air and water. Water containing bubbles is less likely to splash when rinsing hair, and it also cleans hair more thoroughly. Compressed air is typically supplied by an air compressor, and water flow is usually driven by a water pump. An electrical supply powers both the air compressor and the water pump. The air compressor, water pump, and power supply are usually housed in a single chamber, resulting in significant noise and severely impacting the user experience. (See Chinese Utility Model Patent; Subject Name: Nano Hair Washing Machine; Publication No.: CN216165773U; Publication Date: 2022-04-05).
