Description

Technical Field

[0001] This utility model relates to the field of household cleaning equipment technology, and in particular to a vacuum cleaner floor brush steering device. Background Technology

[0002] Vacuum cleaners, as essential tools for both home and commercial cleaning, rely heavily on their floor brushes. Traditional vacuum cleaner floor brushes are often fixed or have only limited oscillation angles, making them inflexible in handling cleaning needs from different directions. This is especially problematic in narrow areas or under furniture, where their maneuverability and operability are poor. To improve cleaning efficiency, floor brush designs with some steering capabilities have emerged in recent years, but their steering flexibility remains insufficient, and their poor operability can easily lead to user fatigue. Most existing vacuum cleaner floor brush steering devices are typically complex in structure, resulting in large size and weight. Prolonged hand operation can cause hand fatigue, hindering extended vacuuming sessions. Furthermore, most floor brush steering devices can only achieve small-angle and small-amplitude rotations, making it difficult to adapt to complex terrain or rapid changes in cleaning paths. The steering response is also often sluggish or jammed, failing to provide a precise and efficient control experience. In addition, existing vacuum cleaner brush steering devices are usually assembled as a single unit, which cannot be disassembled for cleaning. This means that the entire vacuum cleaner needs to be moved when cleaning the vacuum cleaner brush, which greatly increases the difficulty and inconvenience of cleaning the vacuum cleaner. Furthermore, the non-separable design of the vacuum hose and the vacuum cleaner brush head creates many obstacles for subsequent maintenance and replacement. Utility Model Content

[0003] This invention overcomes the shortcomings of the prior art and provides a vacuum cleaner floor brush steering device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0031] Example

[0032] like Figure 1-5 As shown, this application provides a vacuum cleaner floor brush steering device, which includes a vacuum cleaner floor brush head 1.

[0033] The vacuum brush head 1 is provided with a first steering cavity 2 above it. The outer ring of the first bearing 3 is embedded in the top of the first steering cavity 2. The inner ring of the first bearing 3 is fitted with a fixed docking column 4. The docking column 4 is provided at the bottom of the second steering cavity 5, so that the second steering cavity 5 can rotate relative to the first steering cavity 2. The top of the second steering cavity 5 is provided with a primary inlet 6. The bottom of the primary inlet 6 is provided with an integrated fixing mechanism.

[0034] The integrated fixing mechanism includes two guide rods 7, which are fixed laterally and parallel to each other to the side wall of the first steering cavity 2. A first arched fixing block 8 and a second arched fixing block 9 are symmetrically distributed on the two guide rods 7. A first electromagnetic device 10 is provided at one end of the first arched fixing block 8, and a second electromagnetic device 11 is installed at one end of the second arched fixing block 9.

[0035] Furthermore, in a preferred embodiment of the present invention, the first steering cavity 2 communicates with the dust inlet 12 at the bottom of the dust suction brush head 1, and a second bearing 13 is fixed at the junction of the first steering cavity 2 and the dust suction inlet 12 at the bottom of the dust suction brush head 1.

[0036] Furthermore, in a preferred embodiment of the present invention, the first steering cavity 2 and the second steering cavity 5 have completely identical shapes and dimensions.

[0037] Furthermore, in a preferred embodiment of the present invention, a secondary inlet 14 is provided in the middle of the docking column 4 to limit the through-drilling suction pipe 15.

[0038] Furthermore, in a preferred embodiment of the present invention, the aperture of the secondary inlet 14 is larger than that of the primary inlet 6, and the aperture of the primary inlet 6 is equal to the diameter of the suction pipe 15.

[0039] Furthermore, in a preferred embodiment of the present invention, a metal ring 16 is provided at the front end of the suction pipe 15, and the metal ring 16 can be attracted to the third electromagnetic device 17 that generates magnetic force after being energized.

[0040] Furthermore, in a preferred embodiment of the present invention, the third electromagnetic device 17 is fixed above the inner ring of the second bearing 13.

[0041] Furthermore, in a preferred embodiment of the present invention, the two ends of the first arched fixing block 8 and the second arched fixing block 9 are respectively connected to the side wall of the second steering cavity 5 with a return spring 18, and the return spring 18 is sleeved around the guide rod 7.

[0042] Furthermore, in a preferred embodiment of the present invention, an arc-shaped damping block 19 is provided on the inner side of the first arched fixing block 8 and the second arched fixing block 9.

[0043] Furthermore, in a preferred embodiment of the present invention, a driven gear 20 is welded to the outside of the first steering cavity 2, the driven gear 20 meshes with the driving gear 21, the driving gear 21 is fixed to the output end of the micro motor 22, and the micro motor 22 is mounted on the side of the second steering cavity 5.

[0044] It should be noted that the vacuuming brush head 1 and the vacuuming pipe 15 of this device are detachable. When vacuuming is required, the first electromagnetic device 10 and the second electromagnetic device 11 are first de-energized. Under the return force of the return spring 18, the first arched fixing block 8 and the second arched fixing block 9 are pulled towards the inner wall of the first turning cavity 2, thereby causing the first arched fixing block 8 and the second arched fixing block 9 to unfold relative to each other. At the same time, the third electromagnetic device 17 is energized and activated, extending the front end of the vacuuming pipe 15 from the primary inlet 6 and passing through the secondary inlet 14, finally reaching the top of the second bearing 13. At this time, the metal ring 16 at the front end of the vacuuming pipe 15 will be aligned and attracted to each other under the magnetic force of the third electromagnetic device 17 after it is energized, so that the vacuuming pipe 15 is connected to the vacuuming inlet 12 through the inner ring of the second bearing 13. Furthermore, under the function of the second bearing, the suction pipe 15 and the vacuuming brush head 1 can rotate relative to each other. At this time, the first electromagnetic device 10 and the second electromagnetic device 11 are energized synchronously. It should be noted that the magnetic poles generated by the first electromagnetic device 10 and the second electromagnetic device 11 after being energized are opposite. Therefore, the first electromagnetic device 10 and the second electromagnetic device 11 will attract each other. The attraction of the two will further drive the first arched fixing block 8 and the second arched fixing block 9 to slide on the guide rod 7, so that the first arched fixing block 8 and the second arched fixing block 9 overcome the return pull of the return spring 18 and stick together to generate a certain fixing force. After sticking together, the arc-shaped damping block 19 will clamp and fix the suction pipe 15 synchronously, realizing the fixed effect of the suction pipe 15 and the first steering cavity 2 forming an integrated unit, and completing the assembly action of the suction pipe 15 and the vacuuming mop head 1. If disassembly and cleaning are required after use, simply disconnect the power input to the first electromagnetic device 10, the second electromagnetic device 11, and the third electromagnetic device 17. Based on the above principle, the first arched fixing block 8 and the second arched fixing block 9 will re-open relative to each other under the return pull of the return spring 18. After the third electromagnetic device 17 eliminates the attraction force on the metal ring 16, it can detach the front end of the suction pipe 15 from the second bearing 13, thus easily removing the suction pipe 15 through the primary inlet 6 and the secondary inlet 14, completing the disassembly of the suction pipe 15 and the vacuum mop head 1. The detachable design of this device facilitates subsequent cleaning and maintenance while allowing for vacuuming direction adjustment. It can be used to clean stubborn deposits such as hair, dust, and debris separately, preventing the vacuum cleaner from clogging or secondary pollution, allowing for cleaning after each use and improving cleanliness. At the same time, assembly and disassembly are quick, eliminating the need for cumbersome steps such as traditional hole aiming and docking, improving cleaning efficiency. In addition, this device is easy to store, pack, or carry, optimizing portability and flexibility compared to traditional vacuuming equipment.

[0045] It should be noted that, in the cleaning operation state with the vacuuming brush head 1 and the vacuum hose 15 assembled, the cleaner holds the vacuum hose 15 with both hands and starts the micro motor 22. The output end of the micro motor 22 drives the drive gear 21 to rotate. The rotating drive gear 21 then drives the meshed driven gear 20 to rotate. Due to the damping clamping of the integrated fixing mechanism, the vacuum hose 15 and the second steering cavity 5 are combined to form a fixed holding unit. And through the rotation setting of the first bearing 3, the rotation of the driven gear 20 will drive the first steering cavity 2 to rotate relative to the second steering cavity 5, thereby causing the vacuuming brush head 1 to turn relative to the vacuum hose 15 held and fixed by both hands, realizing the automatic turning effect of the vacuuming brush. Because of the setting of the first bearing 3, the vacuuming brush head 1 can achieve 360° all-round turning. The number of rotations of the driven gear 20 can be controlled according to the cleaning needs, thereby freely adjusting the turning angle. The infinitely steerable floor brush of this device can perform vacuuming and cleaning tasks in narrow spaces, under furniture, corners, and other areas, making it easier to turn around, navigate around obstacles, and avoid them. Compared with traditional floor brushes, there is no need to manually lift and adjust the direction repeatedly, saving time and effort, reducing arm or wrist fatigue caused by frequent turning or applying too much force, and providing greater practicality and convenience.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
