Description

cleaning device

This creation relates to a cleaning device.

A common cleaning device uses a sponge head to provide water-absorbing cleaning and absorb water stains. The sponge head is columnar, although its cleaning surface has multiple convex lines. However, when the cleaning surface is pressed down for cleaning, the protruding strips will be pressed down into a flat shape, resulting in a large contact area with the ground, so the resistance when dragging is large, and it is relatively laborious and prone to bouncing when pushing; Otherwise, the cleaning effect in a single wipe is not good.

Therefore, it is necessary to provide a novel and progressive cleaning device to solve the above-mentioned problems.

The main purpose of this creation is to provide a cleaning device that can reduce the resistance generated during cleaning, so as to smoothly drag and clean, and has good cleaning power.

In order to achieve the above purpose, the invention provides a cleaning device, including: a cleaning main body, which includes a cleaning surface and at least one convex portion, each of the convex portions is located on the cleaning surface, each of the convex portions is provided with a groove, and the concave A depth of the groove is smaller than a height of the at least one protrusion.
