Waterproof wheel of floor washer

Abstract

The invention provides a waterproof wheel of a floor washer. The waterproof wheel comprises a wheel, a bearing, a shaft core and an outer sealing cover which is arranged on the outer side of the bearing and fixed with the shaft core. The inner side of the bearing is provided with an inner sealing cover which is sleeved on the periphery of the shaft core. The shaft core is provided with an inner barrier and a groove, the inner sealing cover is covered on the outer periphery of the groove, the inner barrier is placed between the inner sealing cover and the bearing, so that the shaft core and the inner sealing cover are combined perfectly, and outside water vapor is prevented form entering into the bearing. Meanwhile, the inner sealing cover and the outer sealing cover are directly embedded into a bearing hole through a convex ring which is made of polyurethane, so that embedding of the inner sealing cover and the outer sealing cover and the wheel is very firm, the inner sealing cover and the outer sealing cover can be easy to mount, not easy to age and abrade, and accordingly the service life of the waterproof wheel is prolonged.

Description

Technical field [0001] The invention relates to a washing machine, in particular to a wheel of the washing machine. Background technique [0002] Hard floors such as terrazzo, marble, granite, artificial stone, floor tiles, PVC, stainless steel sand, epoxy, etc. The traditional cleaning method is to use a mop to add dust, which is more laborious and labor intensive. If it is a station, dock, airport, workshop, warehouse, school, hospital, restaurant, store, and other places with broad hard ground, the traditional cleaning method is not applicable. At present, floor scrubbers are often used for cleaning, replacing manpower with machinery, which is labor-saving, fast, efficient and clean, and its work efficiency is generally more than ten times that of manpower. The floor scrubber is a cleaning machine that is used to clean the floor while absorbing the sewage and take the sewage away from the site. It consists of a brush head that cleans the floor, a squeegee that sucks the sewag...

AI Technical Summary

Problems solved by technology

Originally, the sealing ring of the bearing is only used to protect the lubricating oil and the flat gasket to block the rollers, but it cannot prevent water vapor from entering the entire shaft.

The washing machine mixes water with various chemical reagents for degreasing and decontaminating to clean the ground. Since the wheels of the washing machine are responsible for the movement and walking of the washing machine, it will be in contact with water and various cleaning liquids for a long time. , these liquids can easily enter the inside of the wheel from the inner side of the wheel and cause corrosion of the wheel bearings, resulting in corrosion of the entire bearing and difficulty in rolling

If the bearing is damaged and the washing machine cannot move or walk, the wheels need to be replaced, and the use cost is relatively high

[0004] In addition, the outer wheel cover of the existing floor washing machine is a plastic cover, and the edge of the plastic cover is inlaid with wire teeth to fix the wheel. Prevent water vapor from entering the bushing and damaging the bearing
