Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment, and in particular to a cleaning tool for full-pipeline ultraviolet and ozone sterilization and disinfection. Background Art

[0002] my country's GDP continues to grow rapidly, consumer income continues to grow, especially the rapid growth of residents' income levels in large and medium-sized cities, and residents' living conditions continue to improve. There are more and more duplex houses and large-area houses, and residents' demand for vacuum cleaners and floor scrubbers is also growing.

[0003] Taking a vacuum cleaner as an example, vacuum cleaners can be divided into vertical, horizontal and portable types according to their structures. Existing vacuum cleaners are mainly composed of a dust body, a dust cup and a floor brush. The vacuum cleaner motor rotates at high speed, sucks in air from the suction port, and makes the dust box produce a certain vacuum. Dust and other debris enter the dust filter bag through the carpet or floor brush, the long pipe, the elbow, the hose and the hose joint in turn, and the dust and other debris are retained in the dust filter bag. After the air is purified by the filter, it is discharged from the tail of the body, which can achieve the cleaning of the floor. However, as vacuum cleaners are more and more widely used in current life, there is also a great demand for accessories used with vacuum cleaners. However, existing vacuum cleaners often have the effects of vacuuming and floor brush cleaning. After vacuuming and floor brush cleaning, there are often more debris and sewage attached to the sewage box and the floor brush head in the vacuum cleaner, and the vacuum duct is a component that is difficult to clean and organize. Long-term storage is prone to internal bacterial growth, forming secondary pollution, which affects the use effect of the vacuum cleaner. Summary of the invention
