Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to an improved dust removal device for vacuum cleaners. Background Technology

[0002] In the rapidly developing home appliance market, handheld vacuum cleaners have become an indispensable tool for modern household cleaning due to their convenience and efficiency. With continuous technological advancements, the design of handheld vacuum cleaners increasingly emphasizes user experience, cleaning efficiency, and device durability. The basic working principle of a handheld vacuum cleaner is to generate negative pressure through a built-in fan, drawing dust-laden air into the vacuum cleaner. The dust particles are then separated by a filtration system, and finally, clean air is expelled. In traditional designs, the fan is often located in the middle or bottom of the vacuum cleaner. This results in the drawn-in air having to pass through a long duct and possible bends before reaching the fan, increasing airflow resistance and the risk of particle retention.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to provide an improved dust removal device for vacuum cleaners that can effectively solve the above-mentioned technical problems.

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0027] like Figures 1 to 6 As shown, an improved dust removal device for a vacuum cleaner includes a handheld part 1 with a battery pack 10, a main unit 2 with a fan chamber 3 located at one end of the handheld part 1, a negative pressure fan 7 located in the fan chamber 3, a dust collection part 5 with a dust collection chamber 4 attached below the main unit 2, a fan hood 6 fixed to the inner wall of the dust collection chamber 4, a filter 60 located in the fan hood 6 and attached to the fan chamber 3, an air inlet channel 8 located at one end of the handheld part 1 and communicating with the fan hood 6, and a floor brush box 9 located at one end of the air inlet channel 8. The battery pack 10 is electrically connected to the negative pressure fan 7, the fan hood 6 is communicating with the dust collection chamber 4, and the negative pressure fan 7 is used to generate air pressure, so that the debris passes through the floor brush box 9 and the air inlet channel 8 into the dust collection chamber 4 in sequence. By placing the fan chamber 3 at the top of the dust collection chamber 4, the airflow can pass through the dust collection chamber 4 more smoothly after entering through the floor brush box 9 and then reach the fan, making the airflow more direct and reducing the detour and energy consumption of the airflow within this embodiment.

[0028] Specifically, the hood 6 has an air vent at one end near the main unit 2, and there is a gap between the air vent and the dust collection chamber 4. The hood 6 is equipped with a spiral air duct 61, and one end of the spiral air duct 61 has an opening 62 for communicating with the air inlet channel 8. Through the cooperation of the spiral air duct 61 and the air inlet channel 8, the airflow can form a spiral airflow when passing through the spiral air duct 61, so that dust and other particles are thrown against the air duct wall by centrifugal force, and then fall into the dust collection chamber 4 through the air vent between the hood 6 and the dust collection chamber 4. The relatively clean airflow enters the fan unit through the filter 60. The dust collection unit 5 plays a pre-interception role, and larger dust particles and debris are intercepted in the dust collection chamber 4, reducing the chance of larger particles entering the fan. This allows the intake air to be initially purified before entering the fan, improving the efficiency of dust-air separation and reducing the risk of wear on the negative pressure fan 7.

[0029] A rubber plate 63 is movably mounted on the opening 62. A sub-pipe 81 is provided at one end of the air inlet channel 8. The rubber plate 63 abuts against the sub-pipe 81. The height of the rubber plate 63 is greater than the height of the sub-pipe 81. The rubber plate 63 has elastic characteristics. In the initial state, the rubber plate 63 covers the opening of the sub-pipe 81. In actual use, the suction force generated by the negative pressure fan 7 causes the rubber plate 63 to bend, thereby connecting the spiral air duct 61 and the air inlet channel 8 through the sub-pipe 81. The airflow carries the garbage through the spiral air duct 61 into the dust collection chamber 4. When the negative pressure fan 7 stops running, the rubber plate 63 automatically rebounds and covers the opening of the sub-pipe 81 again, preventing the dust remaining in the spiral air duct 61 from leaking out, and further enhancing the cleaning effect.

[0030] One end of the main unit 2 is provided with a switch button 20 connected to the battery pack 10 wire. The switch button 20 is used to control the battery pack 10 to supply power to the negative pressure fan 7. One end of the main unit 2 is provided with an adjustment button 21, which is connected to the negative pressure fan 7 wire and is used to adjust and control the negative pressure suction of the negative pressure fan 7.

[0031] One end of the dust collection section 5 is provided with a dust discharge port 50, and a cover plate 51 is movably connected to the dust discharge port 50. The cover plate 51 is used to close the dust collection chamber 4. In this embodiment, one end of the cover plate 51 is movably connected to the dust discharge port 50, and the other end of the cover plate 51 is snapped into the dust discharge port 50. The cover plate 51 is provided with a rubber strip 52 that abuts against the dust discharge port 50. When the dust in the dust collection chamber 4 is full, the dust can be poured out by opening the cover plate 51. By setting the rubber strip 52, the dust in the dust collection chamber 4 can be effectively prevented from leaking from the dust discharge port 50.

[0032] Working principle: Pressing the switch button 20 enables the battery pack to supply power to the negative pressure fan 7, thereby generating negative pressure in the negative pressure fan 7. This causes the airflow to carry the garbage through the floor brush box 9 and into the air inlet channel 8. Subsequently, the airflow carries the garbage through the spiral air duct 61, causing large particles such as dust and garbage to be thrown against the air duct wall by centrifugal force. Then, they fall into the dust collection chamber 4 through the gap between the fan cover 6 and the dust collection chamber 4.
