Brush

Abstract

The invention provides a brush of which bristles can still be closely attached to a pond wall for cleaning operation under the condition that a pond is filled with water. The brush comprises a brush head (1) and a brush handle (2), wherein the brush handle (2) is fixed on the brush head (1), and the bristles (3) are arranged on the brush head (1). The brush is characterized by also comprising a power-assisting plate (4) which is rotatably connected with the brush head (1), and a limiting mechanism (5) which is used for limiting an included angle (beta) formed by the power-assisting plate (4) and the brush handle (2) to be within a range of 20-60 degrees is arranged between the power-assisting plate (4) and the brush handle (2).

Description

technical field [0001] The invention relates to a brush, in particular to a brush for cleaning pool walls. Background technique [0002] In the prior art, the brushes used to clean the pool wall mostly adopt the brushes as attached figure 1 The structure shown in , which includes a brush head 01 and a brush handle 02, the brush head 01 is equipped with bristles 03, and the brush handle 02 has two kinds of short handle structure and long handle structure. The brush with the above-mentioned structure can play a good role in cleaning the pool wall when there is no water in the pool. But when the pool is full of water, when the brush of the above structure cleans the pool wall, due to the resistance of the water, the bristles on the brush head are difficult to ensure that they are always pressed against the pool wall during the back and forth brushing process. For example, when the user presses the bristles on the pool wall with force, the bottom of the brush head will give th...

Problems solved by technology

However, when the pool is full of water, when the brush of the above structure cleans the pool wall, due to the resistance of the water, it is difficult to ensure that the bristles on the brush head are always pressed against the pool wall during the back and forth brushing process.

For example, when the user presses the bristles on the pool wall with force, the bottom of the brush head will give the brush a large reaction force due to the buoyancy of the pool water, and most of the user's downward pressure will be buffered. This kind of reaction force is not completely vertical upwards, plus the horizontal force of the waves received by the brush in the water, it is difficult for the bristles to stick to the pool wall, so when the user uses the brush with the above structure to clean the pool wall, it is often necessary to use a brush to clean the pool wall. Press the brush against the pool wall with one hand, and pull the brush up and down with the other hand, which is very laborious to operate, and the brush is often not close to the pool wall, and its cleaning effect is difficult to exert
