[0002] A pneumatic vacuum cleaner brush head is a highly efficient cleaning tool that uses compressed air as a power source.
[0003] The edges of pneumatic brushes are more prone to friction, causing the bristles on the edges of the roller brush to wear out more quickly. The bristles in the middle of the pneumatic brush wear less, so replacing the entire brush disc directly inevitably leads to a waste of resources.
[0004] The existing patent (publication number: CN209284456U) discloses a combined pneumatic brush. This combined pneumatic brush allows for easy disassembly and replacement of sub-brush discs at different positions on the lower part of the brush disc. This facilitates the replacement of the outer ring of the pneumatic brush, which is more prone to wear, thus ensuring the effectiveness of the pneumatic brush and reducing resource waste.
[0005] To address the aforementioned issues, existing patents have provided solutions. However, some existing pneumatic vacuum cleaner brush heads are not convenient to hold flexibly or adjust to multiple angles, making it inconvenient to hold the pneumatic vacuum cleaner brush head to clean the objects that need cleaning.
[0006] Therefore, an easily adjustable pneumatic vacuum brush head is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-5 The present invention provides the following technical solution:
[0028] An easily adjustable pneumatic vacuum cleaner brush head includes a fixing ring 1, a vacuum tube 3 fixedly connected to the top of the fixing ring 1, an adjustment mechanism 5 provided on the front side of the vacuum tube 3, and a brushing mechanism 2 provided at the bottom of the vacuum tube 3.
[0029] The adjustment mechanism 5 includes two limiting rings 501, two threaded posts 502, an adjustment plate 503, and a support plate 504. The threaded post 502 is fixedly connected to the adjustment plate 503 on the side closest to the adjustment plate 503. The limiting ring 501 is threadedly connected to the surface of the threaded post 502. The front side of the adjustment plate 503 is fixedly connected to the rear side of the support plate 504.
[0030] In this embodiment: External compressed air enters the multi-pass air channel 203 within the fixed ring 1 through the air inlet pipe 11, and is distributed to the pneumatic bearing 202 to drive the brush bristles 201 to rotate at high speed. The operator can flexibly control the movement of the brush head by holding the handle 6 with rubber anti-slip sleeves 7 and the carrying handle 4. When adjusting the tilt angle of the brush bristles 201, the limiting ring 501 is loosened, and the threaded column 502 rotates within the rotating block 10. After adjusting the angle of the fixed ring 1, the brush bristles 201, and the suction pipe 3, the limiting ring 501 is locked. The brush bristles 201, after angle adjustment, facilitate precise cleaning of areas of different shapes or depths. The carbon fiber composite nylon brush bristles 201 are high-strength, wear-resistant, and anti-static. The suction pipe 3 is connected to external equipment, brushing away dust while simultaneously sucking in and expelling it under negative pressure, resulting in efficient cleaning. This solves the problem that some existing pneumatic vacuum brush heads are inconvenient to hold flexibly, inconvenient to adjust to multiple angles, and inconvenient to hold the pneumatic vacuum brush head to flexibly clean the objects that need cleaning.
[0031] Specifically, such as Figure 4 As shown, the brushing mechanism 2 includes several brush bristles 201, a pneumatic bearing 202, and a multi-pass air supply channel 203. The multi-pass air supply channel 203 is opened inside the fixed ring 1. The bottom of the brush bristles 201 is fixedly connected to the rotating end of the pneumatic bearing 202, the bottom of the pneumatic bearing 202 is fixedly connected to the top of the fixed ring 1, and the multi-pass air supply channel 203 is connected to the air inlet end of the pneumatic bearing 202.
[0032] Specifically, such as Figure 2 As shown, an air inlet pipe 11 is provided on the left side of the fixed ring 1, and the right side of the air inlet pipe 11 extends into the interior of the fixed ring 1 and is fixedly connected to the multi-pass air supply channel 203.
[0033] Specifically, such as Figure 4 As shown, a handle 9 is fixedly connected to the rear side of the fixing ring 1.
[0034] In this embodiment: the multi-pass air supply channel 203 in the brushing mechanism 2 is located inside the fixed ring 1 and is connected to the air inlet end of the pneumatic bearing 202. The air inlet pipe 11 distributes compressed air to each pneumatic bearing 202 through the multi-pass air supply channel 203, driving the brush bristles 201 to rotate at high speed to achieve efficient cleaning. The handle 9 is convenient for operators to carry and move the whole device, improving the ease of use.
[0035] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, rotating blocks 10 are fixedly connected to both sides of the top of the fixed ring 1, and threaded post 502 is rotatably connected inside the rotating block 10. The surface of the limiting ring 501 is in close contact with the surface of the rotating block 10.
[0036] Specifically, such as Figure 1 and Figure 3As shown, a handle 4 is provided on the top of the support plate 504, and a rotating plate 12 is fixedly connected to the bottom of the handle 4. A rotating shaft 13 is rotatably connected inside the rotating plate 12. A rotating hole 8 is opened inside the support plate 504, and the rotating shaft 13 is rotatably connected inside the rotating hole 8.
[0037] In this embodiment: the top rotating block 10 of the fixed ring 1 is rotatably connected to the threaded post 502, and the limiting ring 501 is in close contact with the surface of the rotating block 10. Loosening or tightening the limiting ring 501 can allow the threaded post 502 to rotate and be fixed within the rotating block 10, thereby facilitating flexible adjustment of the angles of the fixed ring 1, the brush bristles 201 and the suction tube 3. After adjustment, the angle is limited by friction to meet the angle requirements of different cleaning scenarios. The top handle 4 of the support plate 504 is rotatably connected to the rotating shaft 13 and the rotating hole 8 through the rotating plate 12, which facilitates the operator to adjust the grip angle of the handle 4 and improves the operating comfort.
[0038] Specifically, such as Figure 1 As shown, a handle 6 is fixedly connected to the front side of the support plate 504, and a rubber anti-slip sleeve 7 is fixedly fitted on the surface of the handle 6.
[0039] Specifically, such as Figure 1 As shown, the material of brush bristles 201 is carbon fiber composite nylon.
[0040] In this embodiment: the rubber anti-slip sleeve 7 on the surface of the front grip 6 of the support plate 504 can enhance the friction when holding the hand, so that the operator can more stably control the direction and force of the brush bristles 201. The brush bristles 201 are made of carbon fiber composite nylon material, which has high strength, wear resistance and anti-static properties. It can effectively remove stains and avoid static electricity adsorption of dust, which may affect the cleaning effect or cause secondary pollution.
[0041] Working Principle: External compressed air enters the multi-pass air channel 203 inside the fixed ring 1 through the air inlet pipe 11, and is then distributed to each pneumatic bearing 202, driving the bristles 201 to rotate at high speed. The operator can then flexibly control the direction and force of the bristle movement by holding the handle 6 and using the rubber anti-slip sleeve 7 to enhance friction. To adjust the cleaning angle, the handle 4 can be rotated, causing the rotating plate 12 to rotate around the rotating shaft 13 within the rotating hole 8, thus providing a comfortable grip angle. When adjusting the tilt angle of the bristles 201, the limiting ring 501 is loosened, allowing the threaded post 502 to rotate inside the rotating block 10, facilitating the adjustment of the angles of the fixed ring 1, bristles 201, and suction pipe 3. After angle adjustment, the limiting ring 501 is locked, ensuring close contact between the surface of the limiting ring 501 and the surface of the rotating block 10, increasing friction. The friction between the surface of the rotating block 10 and the adjusting plate 503 is also increased. The frictional force limits the adjustable angle of the bristles 201, enabling precise cleaning of areas of different shapes or depths. The bristles 201 are made of carbon fiber composite nylon, ensuring sufficient strength and wear resistance while effectively dissipating static electricity, preventing dust from being difficult to remove or causing secondary pollution due to static adsorption. The suction tube 3 connects to an external vacuum cleaner. While the bristles 201 brush away dust, negative pressure is used to suck in and expel the dust, achieving efficient cleaning. This solves the problem that some existing pneumatic vacuum cleaner brush heads are inconvenient to hold flexibly, inconvenient to adjust to multiple angles, and inconvenient to hold and clean objects flexibly. It should be noted that the pneumatic bearing 202 is a mature technology that has been published and will not be elaborated here. The rotation speed of the bristles 201 driven by the pneumatic bearing 202 can be controlled by controlling the pressure of the external compressed air, making it convenient to brush away dust with different adhesion.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
