Description
Technical Field
The utility model relates to a brush head structure of a cleaning brush, and belongs to the technical field of cleaning brushes.
Background
The traditional cleaning brushes are all flat brushes, and the brush disc is fixedly connected with the brush handle, but when the curved surface (such as the appearance of a car) of an object to be cleaned is cleaned, the flat brushes in the fixed form are difficult to be completely attached to the curved surface, so that the contact area is small, and the object to be cleaned can be cleaned in place only by repeatedly brushing.
In order to solve the problems, the utility model patent with the application number of CN201920251513.8 discloses a brush head and a cleaning brush, wherein a brush disc is connected with a brush plate through a ball head connecting piece and supported by a spring, so that the angle of the brush disc can be changed and floated, the brush head can adapt to the surfaces with different curved surfaces, and the brush head and the cleaning brush can be automatically attached, so that the cleaning is thorough and efficient, and the aim of better cleaning is achieved.
However, the spring metal parts exist in the structure, and rust prevention of the metal parts becomes a big problem because the cleaning brush is contacted with water and cleaning agent for a long time. If a stainless steel spring with good rust resistance is adopted, the cost can be greatly increased; if the rust resistance of the spring is poor, the service life of the spring is greatly reduced, and the product quality is greatly influenced.

The ball head connecting structure can enable the brush disc to rotate at any angle, so that the brush disc can adapt to different surfaces, is automatically attached, is thoroughly and efficiently cleaned, and achieves a better cleaning purpose. And all parts can be made of nonmetallic materials, so that the rust problem is avoided while the cost is reduced, and the service life of the product is prolonged.
Further, the ball head can move back and forth in the accommodating cavity, and an elastic piece is arranged between the ball head and the bottom of the accommodating cavity, so that a buffering effect can be achieved, and a floating effect is achieved.
Preferably, the elastic member is a polyurethane elastic ball having excellent elastic properties, which also has good abrasion resistance.
The ball head is provided with an inner concave surface which is matched with the polyurethane elastic ball.
The limiting mode of the ball head of the connecting rod in the accommodating cavity is as follows: the connecting cylinder is provided with a plurality of openings along the axis direction of the connecting cylinder, the side wall of the connecting cylinder is divided into a plurality of parts, the outer wall of the connecting cylinder is provided with threads, and the connecting cylinder is screwed with nuts which can polymerize the parts of the side wall together, so that the ball head is prevented from falling out of the accommodating cavity.
Preferably, the nut is round or square in shape.
Preferably, the outer surface of the nut is provided with anti-slip stripes.
The connecting cylinder is connected with the brush handle through the elbow.
Preferably, the brush disc, the connecting rod and the ball head are integrally formed.
Compared with the prior art, the utility model has the following beneficial effects:
the brush head structure of the cleaning brush is more reasonable in structural design, small in size and convenient to use and carry. The ball head connecting structure can enable the brush disc to swing at any angle within a certain range, so that the brush disc can adapt to different surfaces, is automatically attached, is thoroughly and efficiently cleaned, and achieves a better cleaning purpose. And all parts can be made of non-metal materials, such as plastics, polyurethane and the like, stainless steel with good rust resistance is not needed, the cost is reduced, the rust problem is avoided, and the service life of the product is prolonged.
