Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to an anti-tangling structure for vacuum cleaners. Background Technology

[0002] Currently, vacuum cleaners use motors and fans to create a partial vacuum, thereby obtaining the airflow used to suck up dust and dirt from object surfaces, such as floors, carpets, furniture, curtains, etc. Motors and fans typically include centrifugal fans and electric motors configured to power centrifugal fans.

[0003] Vacuum cleaners are frequently used to clean various indoor environments. In most indoor environments, extremely long and tough natural and / or synthetic fibers, such as human hair, lint, yarn, pet hair, and mixed fiber debris, can easily accumulate in the vacuum cleaner's dustbin, leading to filter clogging and increased cleaning power consumption.

[0004] To address this issue, we developed an anti-tangling structure for vacuum cleaners. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art by providing an anti-tangling structure for a vacuum cleaner, which has the advantages of convenient installation, prevention of clogging, reduced power consumption, and improved stability.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an anti-tangling structure for a vacuum cleaner, comprising a dust cup, a dust cup filter frame inserted and sealed to the inner wall of the top of the dust cup, a filter screen surrounding the dust cup filter frame, a filter plate sealed between the outer wall of the filter screen and the inner wall of the dust cup, a lower HEPA cover inserted to the top of the dust cup filter frame, and an upper HEPA cover inserted to the bottom of the dust cup, a dust cup cyclone body provided at the inner bottom of the dust cup, the top of the dust cup cyclone body being inserted into the upper HEPA cover, and a front dust cup cover snapped into the bottom of the dust cup.

[0007] Preferably, a vertical arc-shaped baffle is provided on the inner wall of the dust cup, the filter plate is provided on one side of the arc-shaped baffle, and a sinking dust collection chamber is provided on the other side.

[0008] Preferably, a dust cup filter holder sealing ring is fitted onto the outer wall of the dust cup filter holder, and the dust cup filter holder sealing ring is pressed and sealed against the inner wall of the dust cup.

[0009] Preferably, the top of the HEPA lower cover is provided with a flange, and a HEPA sealing ring is fitted onto the flange.

[0010] Preferably, a vacuum pump is snapped onto the inner wall of the dust cup, and the vacuum pump is press-sealed with the HEPA sealing ring.

[0011] Preferably, a groove is provided at the bottom end of the dust cup front cover, and the groove is used to engage a dust cup connector.

[0012] Preferably, a hook is provided on the side wall of the front cover of the dust cup, and the hook engages with the inner wall of the dust cup.

[0013] Preferably, a dust cup baffle is provided on the lower side of the filter plate, and the top of the dust cup baffle is fixedly connected to the inner wall of the dust cup.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The anti-tangling structure of the vacuum cleaner described in this utility model features a dust cup that snaps into the front cover and is press-sealed with the dust cup filter frame, simplifying the structure and facilitating installation. Simultaneously, the vortex structure within the dust cup cyclone body enhances suction stability and reduces the failure rate, eliminating the need for additional manual operation. The filter plate filters the air-fuel mixture, and the arc-shaped baffle creates internal negative pressure to divert airflow, cleaning a larger amount of indoor impurities in a single pass without clogging the HEPA filter. During vacuuming, it prevents natural and / or synthetic fibers from tangling and clogging the steel filter mesh, thus maintaining airflow and preventing increased motor power consumption.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] Figures 1 to 3 A dust cup anti-tangling structure for a vacuum cleaner includes a dust cup 1. A dust cup filter frame 7 is inserted and sealed to the inner wall of the top of the dust cup 1. A steel filter screen 8 is surrounded by the dust cup filter frame 7. A filter plate 2 is sealed between the outer wall of the filter screen 8 and the inner wall of the dust cup 1. The filter plate 2 is fixedly connected to the bottom of the dust cup 1. A HEPA lower cover 6 is inserted into the top of the dust cup filter frame 7, and a HEPA upper cover 9 is inserted into the bottom. The filter screen 8 is sealed between the HEPA upper cover 9 and the HEPA lower cover 6. A dust cup cyclone body 10 is provided at the bottom of the dust cup 1. The top of the dust cup cyclone body 10 is inserted into the HEPA upper cover 9. A dust cup front cover 11 is snapped into the bottom of the dust cup 1. A groove 111 is provided at the bottom of the dust cup front cover 11, which snaps into a dust cup connector 12. A hook 112 is provided on the side wall of the dust cup front cover 11, which snaps into the inner wall of the dust cup 1.

[0020] A vertical arc-shaped baffle 3 is provided on the inner wall of the dust cup 1, and the arc-shaped baffle 3 is set opposite to the direction of the rotating cyclone. A filter plate 2 is provided on one side of the arc-shaped baffle 3, and a sinking dust collection chamber 109 is provided on the other side. Some small impurities are intercepted by the filter plate, while larger fibers are diverted into the sinking dust collection chamber. A vacuum pump is snapped into the inner wall of the dust cup 1, and the vacuum pump is pressed and sealed with the HEPA sealing ring 4. After the negative pressure of the internal vortex generates diversion, a larger amount of indoor impurities can be cleaned in a single operation, making it less likely to clog the HEPA filter.

[0021] A rubber dust cup baffle 13 is provided on the lower side of the filter plate 2. The top of the dust cup baffle 13 is fixedly connected to the inner wall of the dust cup 1. Under negative pressure, the dust cup baffle 13 is sucked up, and mixed impurities enter the dust cup. When it is not clean, the dust cup baffle 13 falls down and closes.

[0022] A dust cup filter holder sealing ring 5 is fitted onto the outer wall of the dust cup filter holder 7, and the dust cup filter holder sealing ring 5 is pressed and sealed against the inner wall of the dust cup 1 to improve cleaning efficiency. The top of the HEPA lower cover 6 is provided with a flange 41, and the flange is fitted with a HEPA sealing ring 4. One end of the vacuum pump abuts against the HEPA sealing ring 4.

[0023] When the vacuum cleaner is working, a large amount of impurities enter the dust cup through the bottom of the dust cup connector 12 and the dust cup cyclone body 10, and enter the interior of the dust cup through the dust cup baffle 13. They rotate along the centrifugal force generated by the spiral air duct on the surface of the dust cup cyclone body 10. Natural and / or synthetic fibers are blocked when they rotate through the filter plate 2. At the same time, when the impurities rotate with the negative pressure airflow, they are diverted when they pass through the arc-shaped baffle 3. Most of the natural and / or synthetic fibers and large-mass impurities enter the sinking dust collection chamber on the right side of the dust cup with the diversion, avoiding a large amount of fiber clogging the filter plate 2. A small amount of natural and / or synthetic fibers and low-mass impurities still rotate with the centrifugal force for further cleaning and separation.

[0024] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
