Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a cleaning brush that is convenient to use. Background Art

[0002] In daily life, a dishcloth is generally used for wiping and cleaning. However, in the kitchen, due to frequent exposure to oil fumes, the kitchen countertops and kitchen equipment are easily stained and become very sticky. It is not easy to clean the ordinary dishcloth, and it is necessary to spray a cleaning agent on the dishcloth first, and then wipe it hard by hand, which easily causes the arms to become sore and tired, and the cleaning is time-consuming and laborious. In addition, when cleaning hard-to-reach high positions such as the bathroom and kitchen walls, people often use a wiping tool with a long handle. However, this tool requires people to keep the wiping tool close to the high position while waving the wiping tool for cleaning, which is very inconvenient. Therefore, when cleaning areas such as the kitchen, bathroom, and toilet that are prone to stubborn stains or bacteria growth, the cleaning brush with better cleaning effect is gradually increasing in use frequency in daily life. The cleaning brush generally includes a handle made of plastic, and a brush head is provided at the head of the handle. Different brush heads are required for cleaning different places, such as hard bristles, soft bristles, scouring pads, etc. However, a cleaning brush is only equipped with one type of brush head, so it is necessary to buy multiple cleaning brushes, which increases the cost and is not conducive to storage.

[0003] In addition, there is also an electric cleaning brush to facilitate people's daily cleaning. It is equipped with multiple brush heads, but the replacement of the brush heads is very cumbersome. At the same time, the electric cleaning brush often has a built-in battery, and a rubber plug is used to plug into the charging port of the battery to prevent water from entering. However, water easily seeps into the charging hole through the gap between the rubber plug and the charging hole, which easily causes the battery to short-circuit and be damaged.

On the back side of the brush head 2, there is an insertion slot 21 that cooperates with the limit clamping block 4. At the opening of the insertion slot 21, there is a clamping projection 22 that protrudes into the insertion slot 21. The insertion slot 21 is a regular hexagon. There are three clamping projections 22 and they are spaced apart on the insertion slot 21. Insert the limit clamping block 4 into the insertion slot 21. At this time, the clamping projection 22 is clamped on the clamping edge to prevent the brush head 2 from falling off, that is, the installation of the brush head can be easily completed, and the method is simple and fast. On the back side of the clamping projection 22, there is an avoidance groove 23. When the limit clamping block 4 is inserted into the insertion slot 21, the edge of the limit clamping block 4 squeezes the clamping projection 22 to bend backward. The avoidance groove 23 provides a deformation space for the clamping projection 22, making the installation of the brush head 2 more labor-saving. Further, there is a gap 24 between both sides of the clamping projection 22 and the edge of the insertion slot 21, which facilitates the deformation of the clamping projection 22 and avoids the side wall of the insertion slot 21 with the clamping projection being squeezed and broken during the insertion of the limit clamping block 4. Further still, the edge of the limit clamping block 4 is inclined from top to bottom to form a guiding surface, and a clamping edge is formed at the lower end of the guiding surface, so as to prevent the clamping projection 2 from being broken when the brush head 2 is disassembled.

[0029] In a preferred embodiment, the brush head 2 is provided with a mounting plate 25, and the mounting plate 25 is provided with a cleaning head, which can be any one of a flat brush, a mushroom brush, a sponge scrubber, a sponge brush, a fiber cloth, and a waxing sponge.
