Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner filter elements, in particular to a vacuum cleaner filter element with a self-sealing structure. Background Art

[0002] As people's living standards and quality of life continue to improve, the use of vacuum cleaners, particularly vacuum cleaners, is increasing in households. A vacuum cleaner filter is a component used to filter and clean dust, dirt, and fine particles from the air. Typically made of fiber material, it captures various airborne pollutants such as dust, pollen, hair, and bacteria. The filter is placed in a specific location inside or outside the vacuum cleaner. Depending on the design, it can be washable and reusable, or disposable.

[0003] When using a vacuum cleaner, air is filtered through the filter element. The captured pollutants remain on the filter element, while clean air flows out through the filter element, keeping the indoor air clean and healthy. The type and performance of the filter element vary depending on the vacuum cleaner brand and model. Users can choose and replace the filter element according to their needs and the vacuum cleaner's recommendations to maintain the vacuum cleaner's efficient operation and good filtering effect.

[0004] However, when installing the filter element, since the filter element needs to be replaced or cleaned regularly, the sealing performance of the filter element after installation may be affected due to operational errors. Therefore, a vacuum cleaner filter element with a built-in sealing structure is needed to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a vacuum cleaner filter element with a self-sealing structure, which has the advantage that the sealing performance remains unchanged after the vacuum cleaner filter element is removed and installed again, thereby solving the problem of poor sealing performance after the vacuum cleaner filter element is removed and installed again.

[0006] To achieve the above object, the present invention provides the following technical solution: a vacuum cleaner filter element with a self-sealing structure, comprising a housing, a filter cartridge movably inserted into the housing, a sealing cover movably mounted on the top of the housing, and a sealing ring;

[0007] The sealing ring is fixedly installed on the outside of the sealing cover;

[0008] The top of the sealing cover is opened and a sealing sleeve is fixedly installed;

[0010] The filter cartridge is designed with stainless steel material, the top of the filter cartridge is provided with an eaves and the eaves is located at the top of the shell, and a filter core is movably inserted in the filter cartridge.

[0011] When using a vacuum cleaner filter element with a self-sealing structure in the present technical solution, the filter core is placed in the filter cartridge and the filter cartridge is directly placed inside the shell. At this time, the connecting pipe can be placed on the top of the filter core, and the sealing cover is put on the top of the shell, and the filter cartridge is positioned and installed on the inside of the shell through the sealing cover. At this time, the top of the connecting pipe passes through the sealing sleeve. When installing the filter element, the shell is directly placed in the dust storage bin of the dust collection equipment, and the limit seat is fixedly connected to the dust storage bin by installing screws, so that the position of the filter element in the dust storage bin is fixed. At the same time, the outer wall of the sealing ring is in contact with the inner wall of the dust storage bin at this time, thereby improving its sealing. When in use, the connecting pipe can be positioned by the sealing sleeve. When the connecting pipe is subjected to suction, the air tightness at the gap on the outer wall of the connecting pipe can be improved by the sealing sleeve.

[0012] Preferably, the outer wall of the shell is provided with reserved grooves in a circular array, the shell is designed with a hard plastic material, and a limit seat is fixedly installed at the center of the bottom circle of the shell.

[0013] Preferably, the limit seat adopts a cylindrical structure design, and the inner wall of the limit seat is provided with an internal thread.

[0014] Preferably, the sealing cover is made of soft rubber material, and a stepped groove is provided on the inner wall of the sealing cover. The inner wall of the sealing cover contacts the housing and the outer wall of the filter cartridge but is not fixedly connected.

[0015] Preferably, the number of the sealing rings is ten, and the ten sealing rings are welded and installed on the outside of the sealing cover at equal distances, and the material of the sealing rings is the same as that of the sealing cover.

[0016] Preferably, the sealing sleeve is made of soft rubber material, has a truncated cone structure, and is glued and mounted on the top of the sealing cover.

[0017] Preferably, the bottom of the communicating tube contacts the upper surface of the filter core but is not fixedly connected, and the outer wall of the communicating tube contacts the inner wall of the sealing sleeve but is not fixedly connected.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] The utility model discloses providing a sealing ring, which is fixedly installed on the outer side of the sealing cover, and opening a hole in the top of the sealing cover and fixing the sealing sleeve. At the same time, a connecting pipe passes through the sealing sleeve. During specific operation, the filter core is placed in the filter cartridge and the filter cartridge is directly placed into the inner side of the housing. At this time, the connecting pipe can be placed on the top of the filter core, and the sealing cover is sleeved on the top of the housing, and the filter cartridge is positioned and installed in the housing through the sealing cover. At this time, the top of the connecting pipe passes through the sealing sleeve. When the filter element is installed, the housing is directly placed in the dust storage bin of the dust collection equipment, and the limit seat is fixedly connected to the dust storage bin by installing screws, so that the position of the filter element in the dust storage bin is fixed. At the same time, the outer wall of the sealing ring contacts the inner wall of the dust storage bin at this time, thereby improving its sealing. When in use, the connecting pipe can be positioned by the sealing sleeve. When the connecting pipe is subjected to suction, the airtightness at the gap of the outer wall of the connecting pipe can be improved by the sealing sleeve, so that the sealing effect is maintained after the vacuum cleaner filter element is taken out and reinstalled.
