[0002] As the quality of life is getting better and better, people have higher and higher requirements for the hygiene of the family environment, but because of the pressure in life and work pressure are also increasing day by day, it is urgent to be freed from the heavy work of household hygiene and cleaning, and in Traditional cleaning methods cannot clean some extremely fine dust on the ground, so there are a large number of household cleaning equipment on the market to improve the hygiene of the family environment, including various brands of sweeping robots, mopping machines, vacuum cleaners, and filters for traditional hand-held vacuum cleaners They are all fixed on the dust cylinder. After long-term use of the vacuum cleaner, it is easy to form a blockage of the filter, resulting in reduced suction of the vacuum cleaner, poor dust collection effect, and even the phenomenon that the motor is blocked and burned, and the motor cannot be turned on. Due to the traditional The dust filter of the handheld vacuum cleaner is fixed on the dust filter and cannot be disassembled. When the filter of the dust filter is blocked, it cannot be disassembled and cleaned. The filter can only be cleaned simply by using tools such as brushes.
