Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of brush, and relates to a toilet brush, in particular to a toilet brush with replaceable brush head. BACKGROUND

[0002] Traditional toilet brushes have various shapes, and usually have a long handle with a head provided with a brush or plastic wire. Hair and dirt are easily stuck between the brush or plastic wire during use of the toilet brush. In addition, the toilet brush is usually stored in a place without ventilation, which is easy to breed bacteria and produce odor.

[0003] Therefore, people have proposed various toilet brushes with replaceable brush heads, such as an automatic cover opening disposable toilet brush (application number 202021657348.5) recorded in Chinese patent documents. The clamping device clamping the cleaning brush belongs to cross clamping, and has the same working principle as scissors. The clamping device is kept clamped by a spring ring and a U-shaped spring for a long time. The tapered chuck slides into the brush head anti-falling groove, and then the clamping device is expanded by the middle ball, so that the ball is clamped in the rotating circular clamping groove. The tapered chuck and the ball are collectively referred to as the chuck. When the chuck of the cleaning brush is in place, the clamping device clamps the chuck inside with the help of the spring ring and the U-shaped spring, ensuring stable connection.

[0004] For example, a toilet brush with replaceable brush head (application number 202120938316.0) recorded in Chinese patent documents. The rubber cotton head includes a rubber cotton part and a fixed part connected with a push rod. The front end of the push rod is integrally provided with a first extension part, and a pull hook is fixedly arranged on the extension part. A second extension part corresponding to the first extension part is integrally arranged on the rod body. The structure of hanging and taking disposable brush head is more convenient than the existing design, the vision is clearer, and it is easier and more convenient to throw away the sponge head after use. In addition, the structure of the hook is more robust, the product life is longer, and the structure is more stable.
