Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaners. Background Technology

[0002] Vacuum cleaners are common cleaning devices used for vacuuming and sweeping floors. However, the dust cups of existing vacuum cleaners often accumulate fine particles of dust and debris over time. These particles easily adhere to the inner surface of the dust cup, especially the filter screen or HEPA filter. When these particles become clogged, the airflow of the filter is significantly reduced, affecting the efficiency of the suction and weakening the vacuum cleaner's fan, increasing energy consumption. Furthermore, the particles adhering to the filter become difficult to clean over time. Additionally, while the dust cups are typically made of transparent material for easy observation, the fine particles adhering to the inner walls can obstruct this view, making it difficult for users to easily monitor the contents of the dust cup. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a vacuum cleaner.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A vacuum cleaner includes a main vacuum unit, a suction hose, and a floor brush. The main vacuum unit is connected to the floor brush via the suction hose. The main vacuum unit includes a body, a fan, and a dust cup. The fan is mounted on the body, and the body has an air intake and an exhaust port corresponding to the fan, and an air intake hose for the suction hose to connect to. The dust cup is installed below the air intake and has a connecting port on its side wall for connecting to the air intake hose. When the fan operates, it generates airflow that passes through the dust cup and is drawn into the suction hose. A filter module is installed inside the dust cup. The airflow passes through the filter module, enters the air intake, and then exits the body through the exhaust port. The dust cup also contains... The scraping mechanism includes a rotating bracket that can rotate within the dust cup. Scraping blades are evenly distributed around the rotating bracket. Each scraping blade includes an inner scraper located inside the rotating bracket and an outer scraper located outside the rotating bracket. The edge of the inner scraper abuts against the filter element on the surface of the filter module, and the edge of the outer scraper abuts against the inner wall of the dust cup. An air guide structure is arranged on the connecting port on the side wall of the dust cup so that the air entering from the connecting port blows towards the scraping blades, pushing the rotating bracket to rotate within the dust cup and causing the inner and outer scrapers to scrape the surface of the filter element and the inner wall of the dust cup.

[0006] The rotating bracket is rotatably mounted on the filter module.

[0007] The filter component on the surface of the filter module is a filter steel mesh surrounding the outside, which forms the surface sidewall of the filter module, and the edge of the inner scraper abuts against the filter steel mesh.

[0008] The filter module includes a cyclone filter cup and a filter bracket with filter cotton and / or filter HEPA. The filter bracket is fixedly installed on the top opening of the cyclone filter cup. An upper annular platform is formed below the top opening of the cyclone filter cup. The side wall of the cyclone filter cup is provided with multiple ventilation holes and is covered with a filter steel mesh. A lower annular platform is provided below the ventilation holes. The rotating bracket is movably fitted on the outside of the filter steel mesh and limited in its installation between the upper and lower annular platforms.

[0009] The rotating support includes an upper collar and a lower collar, as well as multiple scraping blades connected between the upper collar and the lower collar. A stabilizing ring is installed at the bottom of the upper ring platform, and a gap is left between the stabilizing ring and the upper ring platform to clamp the upper collar.

[0010] The lower ring platform is detachably installed on the cyclone filter cup.

[0011] The outer scraper is shorter than the inner scraper, and the outer scraper is located at the lower part of the connecting opening.

[0012] The scraping blade includes a connecting post and inner and outer scraping strips disposed on the inner and outer sides of the connecting post. The outer surface of the connecting post gradually slopes downward and inward. One edge of the outer scraping strip is in close contact with the inner wall of the dust cup, and the other side is attached to the outer surface of the connecting post.

[0013] The beneficial effects of this utility model are as follows: The dust cup of this utility model is equipped with a scraping mechanism inside, which can scrape and remove dust and other fine debris from the inner wall of the dust cup and the filter components on the surface of the filter module when the vacuum cleaner is working. On the one hand, it cleans the dust or debris adhering to the filter components in a timely manner, ensuring that the filter components are not blocked, maintaining the flow of suction air, and avoiding a reduction in the working efficiency of the fan; on the other hand, it ensures the visibility of the dust cup, allowing users to more easily observe the internal condition of the dust cup; in addition, the scraping mechanism is driven to rotate by the air entering the dust cup, without the need to add other drive mechanisms, the structural modification is small, and the modification of the dust cup to add a scraping mechanism is simpler.

[0020] Reference Figures 1 to 5 A vacuum cleaner includes a vacuum cleaner main unit 1, a vacuum hose 2, and a floor brush 3. The vacuum cleaner main unit is connected to the floor brush 3 through the vacuum hose 2. The vacuum cleaner main unit 1 includes a body 11, a fan 12, and a dust cup 13. The fan 12 is installed on the body 11. The body 11 is provided with an air intake 15 and an air exhaust 16 corresponding to the fan 12, and is also provided with an air intake pipe 14 for the vacuum hose 2 to be inserted into. The dust cup 13 is installed below the air intake 15 and has a connecting port 17 on its side wall to connect with the air intake pipe 14. When the fan 12 is working, it generates airflow that passes through the dust cup 13 and is drawn into the air intake pipe 14.

[0021] A filter module 4 is installed inside the dust cup 13. The suction airflow passes through the filter module 4 into the air intake 15 and then exits from the exhaust 16 into the main body 11. A scraping mechanism 5 is also provided inside the dust cup 13. The scraping mechanism 5 includes a rotating bracket 51 that can rotate within the dust cup 13. Scraping blades are evenly distributed around the rotating bracket 51. The scraping blades include an inner scraper 52 located inside the rotating bracket 51 and an outer scraper 53 located outside the rotating bracket 51. The edge of the inner scraper 52 abuts against the filter element on the surface of the filter module 4, and the edge of the outer scraper 53 abuts against the inner wall of the dust cup 13. A guide structure 6 is arranged on the connecting port 17 on the side wall of the dust cup 13, allowing air to enter through the connecting port 17. The wind blows towards the scraping blades, pushing the rotating bracket 51 to rotate inside the dust cup 13, causing the inner scraper 52 and outer scraper 53 to scrape the surface of the filter element and the inner wall of the dust cup 13, removing dust and other small debris. On the one hand, it cleans the dust or debris adhering to the filter element in a timely manner, ensuring that the filter element is not blocked, maintaining the flow of suction air, and avoiding a reduction in the working efficiency of the fan 12; on the other hand, it ensures the visibility of the dust cup 13, allowing users to more easily observe the internal condition of the dust cup 13. In addition, the scraping mechanism 5 is driven to rotate by the wind entering the dust cup 13, without the need to add other drive mechanisms, resulting in minimal structural modifications and making the modification of the dust cup 13 to add the scraping mechanism 5 simpler.

[0022] The rotating bracket 51 of the scraping mechanism 5 can be movably mounted on the inner wall of the dust cup 13 or rotatably mounted on the filter module 4. A preferred embodiment of this invention is that the rotating bracket 51 is rotatably mounted on the filter module 4, minimizing modifications to the interior of the dust cup 13. Furthermore, the filter module 4 can be removed from the dust cup 13, simplifying modifications, assembly, and even maintenance of the scraping mechanism 5. Specifically, the filter module 4 includes a cyclone filter cup 41 and a filter bracket 42 fitted with filter cotton and / or HEPA filter. The filter bracket 42 is fixed to the top opening of the cyclone filter cup 41. An upper annular platform 44 is formed below the top opening of the cyclone filter cup 41. The sidewall of the cyclone filter cup 41 is provided with multiple ventilation openings and is externally covered with a filter steel mesh 43. The filter steel mesh 43 is a filter component on the surface of the filter module 4 and constitutes the surface sidewall of the filter module 4. The edge of the inner scraper 52 abuts against the filter steel mesh 43. A lower annular platform 45 is provided below the ventilation openings. The rotating bracket 51 is movably fitted onto the outside of the filter steel mesh 43 and is limited and installed between the upper ring platform 44 and the lower ring platform 45, allowing for stable rotation between the upper and lower ring platforms 44 and 45. Further, the rotating bracket 51 includes an upper collar 511 and a lower collar 512, as well as multiple scraping blades connecting the upper and lower collars 511 and 512. A stabilizing ring 46 is installed at the bottom of the upper ring platform 44, with a gap between the stabilizing ring 46 and the upper ring platform 44 to clamp the upper collar 511, further reducing the axial range of motion of the rotating bracket 51 and making its rotation more stable. To facilitate assembly of the above structure, the lower ring platform 45 is detachably mounted on the cyclone filter cup 41. The rotating bracket 51 and the stabilizing ring 46 are fitted onto the cyclone filter cup 41 from bottom to top and assembled before the lower ring platform 45 is installed and fixed.

[0023] As a preferred embodiment of this utility model, since the surface of the inner wall of the dust cup 13 does not have many small holes like the filter steel mesh 43, the fit between the inner wall of the dust cup 13 and the outer scraper 53 will be tighter. Therefore, the length of the outer scraper 53 is made shorter than that of the inner scraper 52 to reduce the influence of the fit between the outer scraper 53 and the inner wall of the dust cup 13 on the rotation of the rotating bracket 51. Furthermore, the outer scraper 53 is positioned at a lower position than the connecting port 17. Since the air entering through the air guide structure 6 will blow slightly downwards at an angle, the air can contact the outer scraper 53 as much as possible, thereby more fully driving the rotating bracket 51 to rotate and enabling the scraping mechanism 5 to perform scraping and cleaning. Furthermore, the scraping blade includes a connecting post 513 and inner scraper 52 and outer scraper 53 disposed on the inner and outer sides of the connecting post 513. The outer surface of the connecting post 513 gradually slopes downward and inward. One edge of the outer scraper 53 is in close contact with the inner wall of the dust cup 13, and the other side is attached to the outer surface of the connecting post 513, so that the area of ​​the outer scraper 53 can be larger, which is also to make more full contact with the air entering from the connecting port 17.
