Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, and in particular to a strip bracket, a strip bracket assembly, a rod assembly equipped with the strip bracket assembly, 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 rod body assembly for a floor scrubber, 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, wherein the upper end of the upper connecting shell is fixedly connected to the handle of the floor scrubber, and the lower end of the lower connecting shell is fixedly connected to the mop head of the floor scrubber, and limiting grooves are provided on the upper and lower side walls of the rod body. 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 respectively extend 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 correspond to each other, so that the upper and lower ends of the rod body are respectively firmly connected to the handle of the floor scrubber and the mop head.

[0004] However, the existing "water-dust circulation" floor scrubber configured with a floor scrubber rod assembly inevitably occupies a large volume, whether it is arranged at the bottom of the water tank or on the body. At the same time, in order to power the floor scrubber rod assembly, the floor scrubber rod assembly also needs to be pulled away to an adapter module for easy power supply. When the user takes or places the water tank or performs maintenance on the floor scrubber body, it is inevitable that water will drip onto the adapter module used to power the floor scrubber rod 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 rod assembly. Utility Model Content
