Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a foldable and rotatable electric cleaning brush. Background Art

[0002] With the development of society, people's living standards are getting higher and higher, and the use of cleaning brushes is becoming more and more popular, especially electric cleaning brushes. As an electric cleaning tool, the electric cleaning brush plays a very important role in production and life; it is widely used in various well-known industries such as industry, agriculture, the tertiary industry and households.

[0003] The electric rotary cleaning brush is a common cleaning brush. The brush head is fixed on the rotary head and driven by a motor to rotate, so as to complete the cleaning work on hard surfaces such as car wheels. Its versatility is reflected in that different brush heads can be installed and fixed, such as round sponge brushes, cylindrical long hair brushes, etc., to cope with the cleaning work in different regions, with different requirements and different processes, so that an electric cleaning brush body can carry multiple brush heads to achieve its multi-functional role.

[0004] When working, different rotary heads need to be replaced. During installation, special angles and positions need to be corresponded, and the installation efficiency is low. When disassembling, a relatively large force is required to pull out. At the same time, with the accumulation of the number of disassembly and assembly times, the fixed structure of the rotary head wears, and it is easy for the installed rotary head to come out, resulting in the whole machine being unable to work.

[0005] Chinese Patent CN218791070U discloses an electric rotary cleaning brush, including a first handle, a power output head movably connected to the first handle, and a quick-change head detachably connected to the power output head. The power output head and the quick-change head are detachably connected through a disassembly device. The disassembly device includes a female socket arranged on the quick-change head and a male socket connected to the power output head. The male socket and the female socket cooperate to connect the quick-change head to the power output head, solving the problem that the quick-change head can be quickly installed on the power output head by setting the male socket and the female socket to cooperate with each other. During installation, only the male socket needs to be inserted into the female socket to connect, without corresponding special angles and positions, and the installation efficiency is high; during disassembly, it is simple to pull out; the fixed structure of the quick-change head will not wear, and it is not easy for the installed quick-change head to come out, resulting in the whole machine being unable to work.
