Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and specifically to a vacuum cleaner that is easy to use. Background Technology

[0002] In the vacuum cleaner industry, the cyclone separator is a core component, its function being to separate dust and air through centrifugal force to improve filtration efficiency. However, most existing cyclone separators are integrally molded with the dustbin or fixed with complex clips and screws. For example, some designs combine the separator with the dustbin through a multi-level nested structure, requiring the sequential disassembly of multiple parts, a cumbersome process that necessitates the use of screwdrivers and other tools. This design forces users to spend a significant amount of time and effort during cleaning, especially for non-professional users, as improper disassembly may damage components. Furthermore, some separators are tightly connected to the motor or air duct, requiring the removal of the entire vacuum cleaner's power module during disassembly, further increasing the complexity of the operation.

[0024] like Figures 1 to 4As shown, a user-friendly vacuum cleaner includes a housing 1 with an air inlet 15, an exhaust port 17 on one side of the housing 1, a connecting groove 2 at one end of the housing 1, a detachable dust collection bin 3 with a connecting port 16 that is snapped into the connecting groove 2, a detachable bin lid 14 that is snapped into one end of the dust collection bin 3, a fan chamber 4 located inside the housing 1 and communicating with the exhaust port 17, a fan housing 6 with a fan 5 snapped into the fan chamber 4, a power cord 28 located at one end of the housing 1 and connected to the power cord of the fan 5, and a start button located on the other side of the housing 1 and connected to the power cord of the fan 5. 29. An air inlet window 7 located at one end of the dust collection bin 3, a HEPA filter 8 snapped into the air inlet window 7, a cyclone channel 9 located in the dust collection bin 3 and equipped with an air inlet duct 90, a cyclone separator 11 inserted into the air inlet duct 90, an air inlet chamber 21 located in the cyclone separator 11, and an air outlet window 10 located on one side of the dust collection bin 3 and communicating with the interior of the air inlet chamber 21; wherein, the power cord 28 is used for external power supply, one end of the cyclone separator 11 is provided with a connecting part 13 for insertion into the cyclone channel 9, the HEPA filter 8 is located between the air outlet window 10 and the air inlet window 7, and the air inlet 15 is internally connected to the connecting part 16. In this embodiment, the fan 5 generates negative pressure, causing the external airflow carrying dust to enter the cyclone channel 9 through the air inlet 15. The airflow enters the dust collection bin 3 through the cyclone channel 9 and forms a vortex airflow. Large dust particles adhere to the inner wall of the dust collection bin 3 through the vortex airflow, while small dust particles follow the airflow through the cyclone separator 11 and enter the air inlet window 7. Subsequently, the airflow that has undergone initial filtration is filtered by the HEPA filter 8, and the filtered airflow enters the fan chamber 4. Finally, it flows out through the exhaust port 17 on one side of the fan chamber 4. In this embodiment, the cyclone separator 11 with a connecting part 13 is inserted into the dust collection bin 3 with the cyclone channel 9, making it convenient for users to install and remove the cyclone separator 11.

[0025] Specifically, the connecting part 13 has a circular cross-sectional shape. One end of the cyclone channel 9 is provided with an air inlet 90 for inserting the connecting part 13. A retaining ring 18 is provided on the outer side of the connecting part 13. The retaining ring 18 is made of plastic and is an integral structure with the connecting part 13. In this embodiment, at least three retaining rings 18 are provided, and the three retaining rings 18 are evenly distributed on the outer side of the connecting part 13. By providing retaining rings 18, the retaining rings 18 abut against the inner wall of the air inlet 90. Due to the plastic material, the retaining rings 18 have deformation characteristics, which facilitates the insertion and fixation of the connecting part 13 and the cyclone channel 9. By providing at least three retaining rings 18, the airtightness of the cyclone separator 11 and the cyclone channel 9 is enhanced.

[0026] Specifically, the connecting part 13 and the cyclone separator 11 are an integral structure, and both the connecting part 13 and the cyclone separator 11 are made of plastic, which makes it easy for the connecting part 13 to be inserted into the air inlet duct 90.

[0027] Furthermore, a plurality of openings 20 are provided on one side of the cyclone separator 11. The openings 20 are inclined in the cyclone separator 11 and are connected to the inner cavity of the cyclone separator 11. In this embodiment, the dust collection bin 3 is connected to the inner cavity of the cyclone separator 11 through the inclined openings 20. The fan 5 generates negative pressure, which causes the airflow in the dust collection bin 3 to enter the inner wall of the cyclone separator 11 through the openings 20. The airflow generates a cyclone airflow in the dust collection bin 3 through the openings 20, which enhances the implementation effect of this embodiment.

[0028] Working principle: Power cord 28 is powered by an external power source. Click the start button 29 to start the fan 5. The fan 5 generates negative pressure, causing the external airflow to carry dust through the air inlet 15 into the cyclone channel 9. The airflow enters the dust collection bin 3 through the cyclone channel 9 and forms a vortex airflow. Large dust particles adhere to the inner wall of the dust collection bin 3 through the vortex airflow, while small dust particles follow the airflow into the cyclone separator 11. They are then filtered by the HEPA filter 8, and the filtered airflow enters the fan chamber 4. Finally, it flows out through the exhaust port 17 on one side of the fan chamber 4. After dust collection is completed, open the bin cover 14, remove the dust collection bin 3 from the connecting groove 2, and remove the cyclone separator 11 from the air inlet 90 to clean the dust.
