Abstract
Description
Technical Field
[0001] The utility model relates to a car washing brush and belongs to the technical field of washing brushes. Background Art
[0002] Traditional cleaning brushes are mostly flat-plate designs. When facing objects with curved structures (such as car bodies), the effective contact area between the flat-plate brush and the curved surface is very limited. This means that in order to achieve the ideal cleaning effect, users need to brush repeatedly, which undoubtedly increases the tediousness of the work and reduces the user experience.
[0003] To solve this problem, the utility model patent with application number CN201920251513.8 introduced a new brush head and cleaning brush design. The brush disc is connected to the brush plate through a ball head connector and supported by a spring. This design allows the brush disc to change angles and float according to the curvature of the cleaning surface, so that it can automatically fit objects with different curved surfaces, achieving a more thorough and efficient cleaning effect.
[0004] However, since the spring is made of metal, long-term contact with water and detergents will cause rust problems. Although the use of stainless steel springs with superior rust resistance can solve this problem, it will significantly increase the cost. On the contrary, if the spring's rust resistance is poor, its service life will be greatly shortened, which will seriously affect the overall quality of the product. In addition, the above-mentioned cleaning brush cannot discharge water and needs to be dipped in water, which will also increase the cleaning workload and inconvenience of use. Utility Model Content
[0005] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a car cleaning brush with a more reasonable structure to solve the above problems.
[0006] The automobile cleaning brush described in the utility model comprises a brush holder, a brush disc is installed on the front of the brush holder, and a ball head is arranged on the back of the brush disc; the front of the brush holder is provided with mounting seats equal in number to the brush disc, a hollow accommodating cavity is arranged in the mounting seats, the ball heads are installed in the accommodating cavity to form a ball head connection structure, a spherical gasket matched with the ball head is arranged between the end of the ball head and the bottom of the accommodating cavity; the inner diameter of the mouth of the mounting seat is larger than the diameter of the ball head, the mouth of the mounting seat is provided with a clamping ring which can prevent the ball head from falling out, and the clamping ring is fixed in the mounting seat by a barb arranged at the mouth of the mounting seat.
[0007] The ball-jointed structure makes the brush disc extremely flexible and can dampen rotation, so that it can adjust the angle at will, easily adapt to surfaces of different shapes, and achieve automatic fit, thus ensuring a more thorough and efficient cleaning. In addition, the design also supports the configuration of multiple brush discs to expand the cleaning area and further improve the cleaning effect. All parts can be made of non-metallic materials, which not only reduces production costs, but also effectively avoids the occurrence of rust problems, thereby significantly extending the service life of the product.
[0008] The clamping ring is a discontinuous ring with a notch so that the diameter of the clamping ring can be elastically contracted to facilitate installation in the mounting seat.
[0009] The utility model also includes a brush handle, wherein the brush handle and the mounting seat are hollow structures, the brush handle is connected to the mounting seat through a water pipe, a water outlet hole is opened in the ball head and penetrates to the surface of the brush plate, and can be connected to a water source to directly spray water for auxiliary cleaning.
[0010] In addition, two brush discs are provided, a gap is left between the two brush discs, and a water outlet device is also provided at the gap.
[0011] Wherein, the water outlet device is a water outlet pipe, which is longitudinally arranged between the two brush plates, and a plurality of water outlets are arranged on the front of the water outlet pipe.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] The car cleaning brush described in the utility model has a reasonable structural design. The brush disc can rotate with damping at any angle and adapt to different surfaces. Whether it is a flat surface or a curved surface, it can automatically fit, clean thoroughly and efficiently, and support the configuration of multiple brush discs at the same time, with a large cleaning area and good cleaning effect. The brush handle and the mounting seat adopt a hollow design and can be connected to a water source. The water spraying function is realized through the water outlet hole in the ball head and the water outlet pipe between the brush discs. There is no need to dip in water repeatedly, which reduces the tediousness of dipping in water for cleaning, simplifies the cleaning process, and improves the cleaning efficiency. In addition, all parts can be made of non-metallic materials, which not only reduces the production cost, but also avoids the problem of metal parts rusting due to long-term contact with water and detergents, thereby significantly improving the service life of the product.
