Description

Technical Field

[0001] This utility model relates to the field of vehicle air purifier technology, and in particular to an impeller structure for a vehicle air purifier. Background Technology

[0002] Car air purifiers are air purification devices specifically designed for car interiors. They use a multi-layer filtration system (such as HEPA filters and activated carbon filters) to adsorb and decompose pollutants in the air, including PM2.5, formaldehyde, odors, and bacteria. They are compact in size and circulate air by a motor driving an impeller.

[0003] While existing car air purifiers primarily rely on filters (such as HEPA filters and activated carbon filters) for filtration, the impeller, as the core component driving air circulation, operates at high speeds for extended periods. Even with filters, some fine dust or particles can penetrate and adhere to the impeller blades with the airflow. Furthermore, vehicles are often used in dusty environments with poor air quality (such as construction sites or sandstorm areas), significantly increasing the impeller's contact with dust. This necessitates manual cleaning with a soft brush. However, due to the small gaps between the blades, the brush cannot reach the inner surface of the blades. Since the blades cannot be disassembled for cleaning, this affects subsequent air circulation. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] like Figures 1 to 9 As shown, this application provides an impeller structure for a vehicle air purifier, including: an impeller body 100 and a disassembly assembly 40. The impeller body 100 includes an upper cover plate 10, a lower connecting plate 20, and blades 30. The upper cover plate 10 is located at the upper end of the blades 30, and the lower connecting plate 20 is located at the lower end of the blades 30. The blades 30 are located in the middle of the upper cover plate 10 and the lower connecting plate 20. The disassembly assembly 40 is disposed at the upper end of the upper cover plate 10 and connected to the blades 30. It is used to install and disassemble the upper cover plate 10 along the upper end of the blades 30, thereby facilitating the rotation of the blades 30 for subsequent cleaning, solving the problem that the inner side of the blades 30 is inconvenient to clean, and improving the cleanliness of the impeller body 100.

[0032] After adopting the above technical solution, since the impeller body 100 includes an upper cover plate 10, a lower connecting plate 20, and blades 30, and since the blades 30 are located in the middle of the upper cover plate 10 and the lower connecting plate 20, the upper cover plate 10 and the lower connecting plate 20 can be connected. Multiple sets of blades 30 together form the impeller body 100 into a whole, which facilitates subsequent air circulation operation. Moreover, the disassembly component 40 is located at the upper end of the upper cover plate 10 and is connected to the blades 30. Thus, the upper cover plate 10 can be disassembled by contacting the upper cover plate 10 to fix the blades 30, making it easy to expose the blades 30 and perform dust cleaning operations on the inner and outer sides of the blades 30. This solves the problem that the impeller body 100 cannot be disassembled and the inner side of the blades 30 cannot be cleaned.

[0033] In an optional embodiment, the disassembly assembly 40 includes a trigger ring 41 located inside the upper cover plate 10. Several sets of connecting blocks 42 are equidistantly connected to the inner side of the trigger ring 41, and pins 43 are equidistantly connected to the inner and outer sides of the trigger ring 41. A support spring 44 is provided on one side of the pin 43, and auxiliary sleeves 45 are distributed and wrapped around the outer sides of both ends of the support spring 44. The pin 43 has an "L" shaped structure, and a fixed connection is formed between the pin 43 and the trigger ring 41. When the user disassembles the upper cover plate 10, the trigger ring 41 is rotated clockwise by the force of the connecting blocks 42, thereby driving the pin 43 to rotate along the inside of the operating groove 14. Under the support of the auxiliary sleeves 45, the pin 43 squeezes the support spring 44, causing the end of the pin 43 to disengage from the inside of the slot 35, thereby facilitating the disengagement of the positioning block 34 from the positioning groove 15.

[0034] During the rotation of the trigger ring 41, all the pins 43 rotate along the inside of the operating groove 14 and move further along the inside of all the slots 35. Finally, the cover body 11 can be pulled upward, causing the positioning groove 15 to slide along the outside of the positioning block 34, thus disassembling the cover body 11.

[0035] In this embodiment, the upper cover plate 10 includes a cover plate body 11, and an outer ring protrusion 13 is integrally formed at the upper edge of the cover plate body 11. A connecting sleeve 12 is installed at the upper end of the cover plate body 11 near the center. An operating groove 14 that matches the pin 43 is opened in the middle of the outer ring protrusion 13. A positioning groove 15 that communicates with the operating groove 14 is opened at the bottom of the cover plate body 11, so that the impeller body 100 can be connected to the output end of the motor. At the same time, the operating groove 14 is convenient to connect with the pin 43, and the positioning groove 15 is convenient to be inserted into the positioning block 34.

[0036] In an optional embodiment, the lower connecting plate 20 includes a connecting plate body 21, and the upper end of the connecting plate body 21 is provided with a number of rotating holes 22 equal to the number of blades 30. A linkage ring 23 is movably connected to the bottom of the connecting plate body 21, and a rubber anti-slip strip 24 is connected to the outer side of the linkage ring 23. The anti-slip strip 24 is made of rubber, which helps to support the lower rotating shaft 32 and facilitate its rotation. At the same time, the linkage ring 23 and the linkage wheel 33 are anti-slip through the anti-slip strip 24.

[0037] In an optional embodiment, the blade 30 includes a blade body 31, and a rotating shaft 32 extends from the upper and lower ends of the blade body 31, respectively. The lower rotating shaft 32 is adapted to the rotating hole 22. A linkage wheel 33 with a diameter larger than the rotating hole 22 is fixedly connected to the bottom of the lower rotating shaft 32. The outer side of the linkage wheel 33 is in contact with the anti-slip strip 24. During the rotation of the linkage wheel 33, the anti-slip strip 24 and the linkage ring 23 can be driven to rotate, which facilitates the synchronous operation of the other linkage wheels 33.

[0038] It should be noted that during the rotation of a single blade body 31, the rotating shaft 32 and the linkage wheel 33 can be driven to rotate, so that the outer side of the linkage wheel 33 will contact the anti-slip strip 24, thereby driving the linkage ring 23 to rotate. During the rotation of the linkage ring 23, all the other linkage wheels 33 will be driven to rotate, further driving the other blade bodies 31 to rotate, so that the blade body 31 can rotate at the same angle, which is convenient for cleaning and also convenient for its reinstallation after cleaning.

[0039] For example, since the top of the upper rotating shaft 32 is fixedly connected with a positioning block 34 that is compatible with the positioning groove 15, and the number of positioning blocks 34 is equal to the number of positioning grooves 15, and a slot 35 that is compatible with the pin 43 is provided on one side of the positioning block 34, the outer ring protrusion 13 can drive the positioning block 34 to rotate during the rotation of the cover plate body 11 driven by the motor, thereby driving the rotating shaft 32 and the blade body 31 to rotate. Under the limiting action of the linkage wheel 33, the connecting plate body 21 is driven to rotate, ensuring that the impeller body 100 can be used normally and that there will be no loosening between the two ends of the blade 30 and the upper cover plate 10 and the lower connecting plate 20 respectively.

[0040] It should be noted that the impeller body 100 is mounted on the attached... Figure 9 Inside the E (car air purifier).
