Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner dust bag technology, and in particular to a vacuum cleaner dust bag with a microporous filter. Background Technology

[0002] With the improvement of living standards and the enhancement of environmental awareness, consumers' requirements for vacuum cleaners are no longer limited to basic cleaning functions, but also pay more attention to their filtration effect, dust removal efficiency, and environmental performance. Vacuum cleaner dust bags with microporous filters can efficiently filter fine particulate matter and prevent secondary pollution, meeting the dual needs of modern families for cleanliness and environmental protection. Therefore, it is necessary to design a vacuum cleaner dust bag with a microporous filter.

[0003] To address this, patent CN201912014U discloses a dust bag for a vacuum cleaner, which includes a pleated filter layer. In this invention, the unfolded area of ​​the filter layer is larger than that of a flat outer filter layer. When the same amount of dust is sucked in, the pleated filter layer has greater air permeability, thereby increasing the overall airflow after dust collection and improving the performance of the vacuum cleaner.

[0004] The dust bag mentioned above is prone to deformation when dust accumulates inside during dust removal, making it inconvenient to use. Therefore, it is necessary to design a dust bag with a microporous filter. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum cleaner dust bag with a microporous filter to solve the problem that existing vacuum cleaner dust bags are prone to deformation due to dust accumulation inside the bag during dust removal, making them inconvenient to use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vacuum cleaner dust bag with a microporous filter, comprising a substrate;

[0007] A wear-resistant structure is fixed to the outside of the substrate, and a support structure is uniformly fixed to the outside of the wear-resistant structure.

[0008] The support structure includes a limiting ring, a mounting groove, and a support frame. The limiting ring is uniformly fixed to the outside of the wear-resistant structure. The limiting ring has a mounting groove inside, and the mounting groove has a support frame inside.

[0009] A top fabric is fixed to the top of the substrate, a bottom fabric is fixed to the bottom of the substrate, a filter structure is fixed to the inside of the substrate, and an inner liner is fixed to the inside of the filter structure.

[0010] Furthermore, the wear-resistant structure includes an adhesive layer, a first wear-resistant layer, and a second wear-resistant layer. The adhesive layer is fixed to the outside of the substrate, the first wear-resistant layer is fixed to the outside of the adhesive layer, and the second wear-resistant layer is fixed to the outside of the first wear-resistant layer.

[0011] Furthermore, the first wear-resistant layer is a glass fiber layer, and the second wear-resistant layer is a polyester fiber layer.

[0012] Furthermore, the limiting rings are symmetrically distributed on both sides of the substrate, and the top view of the limiting rings is arc-shaped.

[0013] Furthermore, the filter structure includes a first adhesive layer, a first filter layer, a second filter layer, and a second adhesive layer. The first adhesive layer is fixed to the inner wall of the substrate, the first filter layer is fixed to the inner wall of the first adhesive layer, the second filter layer is disposed on one side of the first filter layer, and the second adhesive layer is fixed to the inner side of the second filter layer.

[0014] Furthermore, the first filter layer and the second filter layer are interwoven to form a spiral structure.

[0015] Furthermore, the outer diameter of the bottom fabric is the same as the outer diameter of the top fabric and the outer diameter of the second wear-resistant layer.

[0016] The advantages of the vacuum cleaner dust bag with microporous filter provided by this utility model are as follows:

[0017] By setting a support structure, the support frame is inserted into the installation groove. Under the limiting action of the limiting ring, the support frame can support the substrate, ensuring that the top and bottom of the substrate are supported, improving the convenience and stability of the substrate during use. This realizes that the device has the function of supporting the dust bag, improving the convenience of using the vacuum cleaner dust bag.

[0018] By incorporating a wear-resistant structure, the first wear-resistant layer is a fiberglass layer, which possesses excellent high-temperature resistance and chemical stability, enabling it to be used in harsh environments such as high temperatures, strong acids, and strong alkalis. It has high filtration efficiency, good air permeability, and is not easily worn. The second wear-resistant layer is a polyester fiber layer, which has strong wear resistance, as well as high heat resistance and chemical stability. It can also be used in harsh environments such as high temperatures and strong acids and alkalis. It has high filtration efficiency, good air permeability, and can effectively capture fine dust, thus enabling the device to have a wear-resistant function and improving the service life of the vacuum cleaner's dust bag.

[0019] By incorporating a filtration structure, the first and second filter layers intertwine to form a spiral structure. This spiral structure generates numerous micropores and gaps for filtering dust. The micropores effectively prevent dust and fine particles from entering the vacuum cleaner, improving filtration efficiency. This design enables the device to perform convenient filtration, thereby enhancing the working efficiency of the vacuum cleaner's dust bag during use. Attached Figure Description
