Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a quick-change mechanism for side brushes used in cleaning equipment. Background Technology

[0002] Currently, the side brush replacement mechanism in cleaning equipment mainly adopts two technical solutions: one is to fix the side brush by screws, and the other is to use magnets for assembly. However, both solutions have significant drawbacks: 1. Screw fixing: Replacing the side brush requires removing the screws, which is cumbersome, usually requires special tools, and is time-consuming, resulting in a poor user experience. 2. Magnets: Although it simplifies the disassembly and assembly process, it is only suitable for assembly scenarios where the side brush is parallel to the ground. If the side brush is tilted or lacks pressure against the ground, it is prone to falling off due to insufficient magnetic force, resulting in insufficient stability.

[0003] Furthermore, existing technologies generally suffer from the problem of separation between the limiting and locking functions, requiring the side brush to be adjusted to the limiting position before an additional locking operation is performed, which is complex and inefficient. At the same time, traditional solutions are difficult to adapt to the need for side brushes to be installed at any angle, limiting the flexibility and practicality of the cleaning equipment.

[0004] The present invention aims to solve the above problems by providing a side brush replacement mechanism that is quick to disassemble, stably locked, and supports installation at any angle of the side brush, so as to improve the convenience and reliability of cleaning equipment.
