CLEANING BRUSH

Description

TECHNICAL FIELD

The present invention relates to a brush, particularly to a cleaning brush.

BACKGROUND

In the field of automobile maintenance and care, interior cleaning of automobiles plays a significant role, due to the complexity of the interior structure and the diversity of spaces, cleaning becomes particularly challenging, traditional cleaning brushes are mostly of a one-piece design, with bristles directly fixed to the brush body, lacking the ability to flexibly replace and adapt to different cleaning needs.

Additionally, existing cleaning brushes mostly rely on manual effort for cleaning, which is inefficient and prone to causing fatigue for the user, therefore, how to design a cleaning brush that can both flexibly adapt to different cleaning needs and improve cleaning efficiency has become an urgent problem to be solved.

SUMMARY

The technical problem to be solved by the present invention is to provide a cleaning brush.

The technical problem to be solved by the present invention is achieved through the following technical solution:

A cleaning brush comprising an upper brush body and a lower brush body, wherein the upper brush body and the lower brush body are in a detachable connection structure, the detachable connection structure includes a connecting body at the lower end of the upper brush body and a connecting hole at the upper end of the lower brush body, the connecting body is provided with an external thread, and the connecting hole is provided with an internal thread, and the external thread is adapted to the internal thread.

The upper brush body is in a bell-shaped structure, and an installation shaft is provided at its upper end.

The lower end of the lower brush body is provided with a brush hair hole, and brush hairs are bonded within the brush hair hole through liquid glue.

The brush hairs are made of nylon, plastic, and boar bristle materials.

The installation shaft can be installed on an electric tool.

The beneficial effects of the present invention are as follows: 1. by adopting the detachable connection design of the upper brush body and the lower brush body, users can easily replace the lower brush body with different materials, hardness, or shapes according to different cleaning tasks and scenarios, this design not only improves the adaptability of the cleaning brush but also extends its overall service life, as users can replace only the worn-out brush hair part without discarding the entire brush; 2. The design of the installation shaft at the upper end of the upper brush body allows the cleaning brush to be conveniently connected to an electric tool for cleaning work powered by the electric tool, this not only significantly improves cleaning efficiency and reduces labor intensity of manual operation but also ensures a more uniform and thorough cleaning effect, especially in hard-to-reach or narrow internal spaces of automobiles; 3. The brush hairs are securely bonded within the brush hair hole through liquid glue, which ensures the stability of the brush hairs; 4. The bell-shaped design of the upper brush body is not only aesthetically pleasing but may also help better distribute the pressure during cleaning, reducing brush head wear and providing better hand feel and operational control, this innovative structural design reflects meticulous consideration for user experience.
