Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaner technology, and in particular relates to a vacuum cleaner dust cup filter assembly with a double-layer filter screen. Background Technology

[0002] The dust cup of a vacuum cleaner is mainly used to collect dust, hair, and other debris sucked in during operation, keeping the inside of the vacuum cleaner clean and preventing performance degradation and damage. As vacuuming continues, the dust cup will gradually fill up, so it needs to be emptied regularly.

[0003] Current vacuum cleaners only have one layer of filter in the dust cup, which can only filter out larger particles such as dust clumps and hair. However, it is not effective at filtering out finer particles such as dust, pollen, and bacteria, which can easily pass through and be released back into the air, causing secondary pollution. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing vacuum cleaner dust cups are only equipped with one layer of filter screen, which can only filter out larger particles such as dust clumps and hair, but has poor filtration effect on finer particles such as dust, pollen, and bacteria, making it easy for these tiny particles to pass through and be released back into the air, causing secondary pollution. Therefore, a vacuum cleaner dust cup filter assembly with a double layer of filter screen is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dust cup filter assembly for a vacuum cleaner with a double-layer filter screen, comprising a dust cup body located at the front side of the vacuum cleaner body, the dust cup body comprising a dust cup shell and a first filter screen, a second filter screen being disposed inside the first filter screen, a suction port being disposed at the front end of the dust cup body, and the rear end of the dust cup body abutting against a motor.

[0006] As a further description of the above technical solution:

[0007] The dust cup housing is fitted onto the outside of the first filter screen.

[0008] As a further description of the above technical solution:

[0009] The first filter screen is cylindrical, and a first mounting ring and a second mounting ring are provided at both ends of the first filter screen. One end of the second filter screen is connected to the first mounting ring, and the other end is connected to the second mounting ring.

[0010] As a further description of the above technical solution:

[0011] The second filter screen is conical in shape, narrow at the front and wide at the back.

[0012] As a further description of the above technical solution:

[0013] The bottom of the dust cup housing is provided with a connecting ear, and the main body of the vacuum cleaner is provided with a button clip, the button clip including a button and a buckle, a spring is provided between the button and the buckle, and the buckle is engaged with the connecting ear.

[0014] As a further description of the above technical solution:

[0015] The suction port is conical in shape.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] In this invention, a double-layer filter is installed in the dust cup. The inner layer blocks large particles, while the outer layer further filters fine particles. The inner filter is designed in a cone shape to increase the filtration area, thus providing more filter media to capture dust and fine particles. Furthermore, due to the gradually narrowing characteristic of the cone structure, larger particles are blocked at the front of the cone, while finer particles are captured at the rear. This design prevents large particles from directly clogging the fine pores of the filter, thereby extending the filter's lifespan. Attached Figure Description
