Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a cleaning brush which is convenient for replacing the brush and adjusting the brush angle. Background Art

[0002] A cleaning brush is a common cleaning tool in daily life, which can help users clean some hard-to-clean places more effectively. A cleaning brush is mainly composed of a grip and a cleaning head. In order to make the cleaning brush more flexible to use, an angle-adjustable structure is used between the cleaning head and the grip, such as a cleaning brush head structure and a cleaning brush described in the utility model patent authorization announcement number CN220001114U. Since the handle can be rotated relative to the brush head, when working in a certain area, the user drives the brush head to move, and does not need to move with the handle. By changing the angle between the handle and the upper surface of the brush head, the displacement of the brush head along the plane to be cleaned can be converted into the displacement of the handle in another direction, thereby reducing the user's movement and reducing the labor intensity during cleaning.

[0003] However, the existing cleaning brushes that can adjust the cleaning head angle generally adopt the traditional multi-speed snap-fitting method between the cleaning head and the gripping part, which mainly relies on forcing the snapping position to switch, so as to achieve the purpose of multi-speed adjustment. However, this forcing method causes greater wear on the snapping position, and it is easy to cause the snapping to be loose after long-term use. In addition, the snapping force between the gripping part and the cleaning head cannot be adjusted, and the gripping part and the cleaning head cannot be in a fixed state or a movable state. Some users hope that the gripping part and the cleaning head can be flexibly rotated to facilitate reciprocating brushing operations, while some users hope that the gripping part and the cleaning head are fixed so that they can accurately align a certain point with the brushed object for brushing. In this regard, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content
