Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, and in particular to a detachable bracket, a detachable bracket assembly, a pole assembly equipped with the detachable bracket, and a floor scrubber. Background Art

[0002] In the early days, people used brooms, mops, floor wipes, etc. to clean the floor. These tools mainly rely on manual operation to complete the cleaning work. With the advancement of science and technology, people's requirements for floor cleaning tools have gradually increased. The first to appear was the vacuum cleaner, which relies on electricity to generate negative pressure to absorb garbage, dust, etc. on the ground. According to the cleaning methods and the circulation channels of small and large particles of garbage, this type of technology is usually classified as air-dust circulation technology. However, due to the limitations of its working principle, the vacuum cleaner cannot clean some garbage and stains that are firmly attached to the ground. Therefore, a new "water-dust circulation" floor scrubber has appeared. The motor drives the cleaning cylinder to wipe the ground. At the same time, the floor cleaner will also be equipped with a water supply system and a sink to clean the cleaning cylinder, thereby perfectly cleaning the ground.

[0003] The prior art CN220175029U discloses a floor scrubber pole assembly, comprising a hollow rod body, an upper connecting assembly and a lower connecting assembly, and also comprising an upper connecting shell and a lower connecting shell, the upper end of the upper connecting shell is fixedly connected to the floor scrubber handle, the lower end of the lower connecting shell is fixedly connected to the floor scrubber mop, and the upper and lower side walls of the rod body are provided with limiting grooves. When the upper and lower ends of the rod body are respectively inserted into the upper connecting shell and the lower connecting shell, the upper connecting shell and the lower connecting shell are respectively extended into the upper docking port of the rod body, and the upper connecting assembly, the upper connecting shell, the lower connecting assembly and the lower connecting shell cooperate with each other, so that the upper and lower ends of the rod body are respectively firmly connected to the floor scrubber handle and the mop.

[0004] However, the existing "water-dust circulation" floor scrubber equipped with a floor scrubber pole assembly inevitably occupies a large volume, whether it is set at the bottom of the water tank or on the body. At the same time, in order to power the floor scrubber pole assembly, the floor scrubber pole assembly also needs to be pulled away to an adapter module that can easily draw power. When the user takes the water tank or performs maintenance on the floor scrubber body, it is inevitable that water will drip onto the adapter module used to draw power for the floor scrubber pole assembly.

[0005] Therefore, it is necessary to find a good solution to perfectly install the power supply, water pump, control panel and other components of the floor scrubber into the floor scrubber pole assembly. Utility Model Content
