Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically a filtration device for vacuum cleaners. Background Technology

[0002] A vacuum cleaner is a device that uses an air pump to create a partial vacuum, generating suction to pick up dust and debris from floors or other locations. The filter in a vacuum cleaner is a filter installed between the suction unit and the dustbin. Its function is to prevent dust sucked into the dustbin from entering the suction unit. Nowadays, most households use vacuum cleaners for cleaning.

[0003] The prior art patent publication number CN218792041U discloses a filter device for a vacuum cleaner, including an upper end cover, a lower end cover, a cylindrical filter core disposed between the upper and lower end covers, and a cleaning device rotatably connected to the upper end cover and extending into the filter core. The cleaning device includes a rotating shaft that passes through the filter core along the axis of the upper end cover and is rotatably connected to the upper end cover, a cap disposed above the upper end cover and fixedly connected to the upper end of the rotating shaft, and at least one hammer assembly disposed at the lower part of the rotating shaft. The hammer assembly includes an elastic element fixedly connected to the rotating shaft at one end, and a... The other end of the component is a hammer that abuts against the inner wall of the filter element. The length of the elastic element is greater than or equal to the length from the rotating shaft to the inner wall of the filter element. The structure is simple and easy to operate. The hammer head bounces as it passes through the folds of the inner wall of the filter element. Combined with the elasticity of the elastic element, the hammer head can continuously strike the inner wall of the filter element, thereby generating vibration and shaking off the dust accumulated in the folds of the filter element. This improves the efficiency and convenience of cleaning dust. At the same time, the hammer head reduces friction with the inner wall of the filter element, avoiding damage to the coating on the surface of the filter paper and reducing wear on the filter paper, thereby increasing the service life of the filtration device.

[0004] Existing technologies mostly use integrated filter devices, which are used to shake out dust by tapping during cleaning. However, the integrated design makes it inconvenient to disassemble and repair the internal filter components if they are damaged. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The filtration mechanism 5 includes a positioning rod 501. The positioning rod 501 is movably arranged inside the dust collection chamber 4. An installation rod 502 is fixedly arranged above the positioning rod 501. Eight limiting plates 503 are fixedly arranged on the outside of the installation rod 502.

[0028] A movable slider 504 is movably mounted above the top plate 1 of the device. A limiting platform 505 is fixedly mounted below the movable slider 504. An installation hole 506 is fixedly mounted on the inner side of the limiting platform 505. The size of the installation hole 506 is the same as that of the installation rod 502. Eight limiting slots 507 are fixedly mounted on the outer side of the installation hole 506. The size of the limiting slots 507 is the same as that of the limiting plate 503. Through the use of the filter mechanism 5, when the internal filter element is damaged, the device can be disassembled by rotating the filter sleeve 3. At this time, the positioning rod 501 and the installation rod 502 in the dust collection chamber 4 can be pulled out, which makes it convenient to replace and repair the adsorption filter plate 7 in the device. Moreover, the movable slider 504 on the top of the device can be rotated during use. The limiting slots 507 cause the limiting plate 503 to drive the installation rod 502 and the positioning rod 501 to rotate, thereby cleaning the dust on the adsorption filter plate 7, making it more convenient to use.

[0029] Eight positioning partitions 6 are fixedly installed on the outer side of the positioning rod 501. The other side of the eight positioning partitions 6 is in contact with the inner surface of the dust collection chamber 4. Correspondingly, an adsorption filter plate 7 is fixedly installed on the inner side of the positioning partitions 6. The adsorption filter plate 7 is conical and its other side is in contact with the inner surface of the dust collection chamber 4. A first mating thread 8 is fixedly installed on the top of the filter sleeve 3. A second mating thread 9 is fixedly installed on the inner side of the mounting sleeve 2. A filter hole 10 is fixedly installed on the inner side of the filter sleeve 3. The size of the filter hole 10 is slightly larger than the size of the filter hole on the adsorption filter plate 7. By using the filter sleeve 3, larger garbage can be filtered through the filter hole 10 on the outer side of the filter sleeve 3 during use. The threaded installation makes it more convenient to install and use.

[0030] Working Principle: This vacuum cleaner's filter device, through the use of filter mechanism 5, allows for disassembly by rotating filter sleeve 3 when the internal filter components are damaged. At this time, the positioning rod 501 and mounting rod 502 inside the dust collection chamber 4 can be pulled out, facilitating the replacement and maintenance of the adsorption filter plate 7. The movable slider 504 on the top of the device can rotate during use, and the limiting slot 507 causes the limiting plate 503 to rotate, thereby cleaning the dust on the adsorption filter plate 7. This makes it more convenient to use. The filter sleeve 3 allows for the filtering of larger debris through the filter holes 10 on its outer side, and the threaded installation makes installation and use more convenient.
