Description

Technical Field

[0001] The invention belongs to the technical field of cleaning equipment, and in particular relates to a brush head with a sealed inner cavity. Background Art

[0002] As the name implies, cleaning equipment is mechanical equipment designed for cleaning. Modern industries involving cleaning include: municipal sanitation, aviation terminals, business buildings, public places, manufacturing workshops, warehousing and logistics, hotels, medical and health care, retail, dams and stadiums, etc. Cleaning equipment plays a role in efficient cleaning in these places. It reduces the labor cost of cleaning while also improving work efficiency and cleanliness, which is indispensable in modern society.

[0003] Traditional cleaning rollers are generally driven by chains or synchronous belts. During the driving process, there will be a large amount of mud and sand on the ground. The mud and sand will adhere to the chain or synchronous belt as the cleaning roller rotates, causing the chain or synchronous belt to wear too quickly. At the same time, some cleaning rollers are directly driven by motors. Since the motor is exposed to the outside of the equipment and the working environment of the cleaning roller is relatively harsh, the motor is prone to water damage after long-term use.
