Technical Field

[0001] This utility model belongs to the field of cleaning brush head technology, specifically an automatic rotating multifunctional cleaning brush head. Background Technology

[0002] Industrial production environments have high dust content, and equipment operating in such environments accumulates a large amount of dust rapidly on its surfaces. Currently used cleaning brush heads have an overly simplistic structure and poor cleaning performance. For example, existing cleaning brush heads rotate in a fixed direction, resulting in constant relative friction between the brush head and the dried foreign matter on the equipment surface. However, based on practical experience, cleaning with a brush head requires reciprocating along the surface of the foreign matter for quick and effective cleaning. Therefore, it is necessary to develop a new type of cleaning brush head to address the shortcomings of existing technologies. Summary of the Invention

[0003] To address the problems mentioned in the background section, this invention provides an automatic rotating multifunctional cleaning brush head, which has the advantage of better cleaning effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic rotating multifunctional cleaning brush head, including a cleaning cylinder, a transmission component connected to the bottom of the cleaning cylinder, an installation component connected to the bottom of the transmission component, and a handle fixedly connected to the outer surface of the cleaning cylinder;

[0005] The transmission assembly includes an inner gear ring movably connected to the bottom of the cleaning cylinder, a coaxial outer gear ring disposed inside the inner gear ring, a transmission gear disposed between the inner gear ring and the outer gear ring, the outer surface of the transmission gear meshing with the inner wall of the inner gear ring and the outer surface of the outer gear ring respectively, a drive motor disposed inside the cleaning cylinder, a transmission shaft fixedly connected to the bottom of the output shaft of the drive motor, and the lower end of the transmission shaft extending to the bottom of the cleaning cylinder and fixedly connected to the top of the transmission gear;

[0006] The mounting assembly includes a first mounting base fixedly connected to the bottom of the inner gear ring and a second mounting base fixedly connected to the bottom of the outer gear ring. The bottom of the first mounting base and the second mounting base are respectively engaged with a first brush plate and a second brush plate, and the bottom of the first brush plate and the second brush plate are connected with brush bristles.

[0007] Preferably, the top of both the inner gear ring and the outer gear ring are fixedly connected to a coaxial rotating retainer, which is rotatably engaged with the bottom of the cleaning cylinder; the bottom of the first mounting base and the second mounting base are provided with two left and right retaining members, and the first brush plate and the second brush plate are respectively engaged with the bottom of the first mounting base and the second mounting base through the retaining members.

[0008] Preferably, the snap-fit ​​component includes a snap-fit ​​groove formed at the bottom of the first mounting base and the second mounting base, a locking block is slidably snapped into the inside of the snap-fit ​​groove, and limiting grooves located on the front and rear sides of the snap-fit ​​groove are formed inside the first mounting base and the second mounting base, and the two sides of the locking block are slidably snapped into the inside of the limiting groove.

[0009] Preferably, a locking spring is abutted on one side of the locking block, the other end of the locking spring abuts against the inside of the snap-fit ​​groove, and a snap-fit ​​connector is press-fitted on the other side of the locking block. The facing surfaces of the snap-fit ​​connector and the locking block are mutually cooperating inclined surfaces.

[0010] Preferably, a spiral blade is fixedly sleeved inside the second mounting base and the external gear ring, and a flow guide is fixedly sleeved in the middle of the cleaning cylinder. The lower end of the flow guide is connected to the upper end of the spiral blade, and the upper end of the flow guide is connected to the interior of the cleaning cylinder.

[0011] The top of the flow guide is provided with a protective cover, and the bottom of the protective cover is fixedly connected with a positioning spring, the lower end of which is fixedly connected to the flow guide.

[0012] Preferably, a protective cover is fixedly connected inside the cleaning cylinder, the drive motor is fixedly installed inside the protective cover, and a sealing cap located on the top of the protective cover is threaded onto the top of the inner cavity of the cleaning cylinder. Two filter vents are threaded onto the inner and outer sides of the sealing cap, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Due to the transmission component, this utility model can drive the mounting component and the brush bristles at its bottom to rotate rapidly, thereby achieving the effect of removing dust. Due to the transmission gear, the inner and outer brush bristles can rotate in opposite directions, thereby improving the effect of drying and solidifying stains.

Finally, with the cooperation of the filter and breathable cover, the dust and foreign objects are retained in the cleaning cylinder.

[0016] 3. Due to the positioning spring, the protective cover can be tightly attached to the top of the guide shroud under the pull of its elastic restoring force. This ensures that the airflow inside the guide shroud can lift the protective cover so that airflow and dust can enter the cleaning cylinder, while preventing dust and foreign objects inside the cleaning cylinder from leaking back through the guide shroud.

[0017] 4. Due to the design of the snap-fit ​​component, the snap-fit ​​connector can be easily inserted into the snap-fit ​​groove by the elastic cooperation of the locking spring on one side of the locking block. At the same time, the locking block can lock the snap-fit ​​connector in the snap-fit ​​groove by the elastic action of the locking spring. This facilitates the disassembly and assembly of the first and second brush plates, and makes it easier to replace worn brush bristles. Attached Figure Description

[0024] 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.

[0025] like Figures 1 to 5 As shown, this utility model provides an automatic rotating multi-functional cleaning brush head, including a cleaning cylinder 1, a transmission component 2 connected to the bottom of the cleaning cylinder 1, an installation component 3 connected to the bottom of the transmission component 2, and a handle 7 fixedly connected to the outer surface of the cleaning cylinder 1.

[0026] The transmission assembly 2 includes an inner gear ring 21 movably connected to the bottom of the cleaning cylinder 1. An outer gear ring 22, coaxial with the inner gear ring 21, is disposed inside the inner gear ring 21. A transmission gear 23 is disposed between the inner gear ring 21 and the outer gear ring 22. The outer surface of the transmission gear 23 meshes with the inner wall of the inner gear ring 21 and the outer surface of the outer gear ring 22, respectively. A drive motor 24 is disposed inside the cleaning cylinder 1. A transmission shaft 25 is fixedly connected to the bottom of the output shaft of the drive motor 24. The lower end of the transmission shaft 25 extends to the bottom of the cleaning cylinder 1 and is fixedly connected to the top of the transmission gear 23. Due to the arrangement of the transmission assembly 2, the mounting assembly 3 and the bristles at its bottom can be driven to rotate rapidly, thereby achieving the effect of removing dust. Furthermore, due to the arrangement of the transmission gear 23, the inner and outer bristles can rotate in opposite directions, thereby improving the effect of drying and solidifying stains.

[0027] Mounting assembly 3 includes a first mounting base 31 fixedly connected to the bottom of the inner gear ring 21 and a second mounting base 32 fixedly connected to the bottom of the outer gear ring 22. The bottom of the first mounting base 31 and the second mounting base 32 are respectively engaged with a first brush plate 33 and a second brush plate 34. The bottom of the first brush plate 33 and the second brush plate 34 are connected with brush bristles.

[0028] like Figure 3 As shown, the tops of the internal gear ring 21 and the external gear ring 22 are both fixedly connected with coaxial rotating retaining rings 26, which are rotatably engaged with the bottom of the cleaning cylinder 1; the bottoms of the first mounting base 31 and the second mounting base 32 are provided with two left and right retaining pieces 35, and the first brush plate 33 and the second brush plate 34 are respectively engaged with the bottoms of the first mounting base 31 and the second mounting base 32 through the retaining pieces 35.

[0029] like Figure 3 and Figure 4 As shown, the snap-fit ​​component 35 includes a snap-fit ​​groove 351 formed at the bottom of the first mounting base 31 and the second mounting base 32. A locking block 352 is slidably snapped into the inside of the snap-fit ​​groove 351. Limiting grooves 353 located on the front and rear sides of the snap-fit ​​groove 351 are formed inside the first mounting base 31 and the second mounting base 32. The two sides of the locking block 352 are slidably snapped into the inside of the limiting grooves 353. Due to the setting of the snap-fit ​​groove 351 and the limiting grooves 353, the locking block 352 can slide smoothly laterally, thereby clamping the snap-fit ​​connector 355 with the cooperation of the inner wall of the snap-fit ​​groove 351, which facilitates the disassembly and assembly of the first brush plate 33 and the second brush plate 34.

[0030] like Figure 4As shown, a locking spring 354 abuts against one side of the locking block 352, and the other end of the locking spring 354 abuts against the inside of the snap-fit ​​groove 351. A snap-fit ​​connector 355 is pressed onto the other side of the locking block 352. The facing surfaces of the snap-fit ​​connector 355 and the locking block 352 are mutually cooperating inclined surfaces. Due to the setting of the snap-fit ​​connector 35, under the elastic cooperation of the locking spring 354 on one side of the locking block 352, the inclined surface on the other side of the locking block 352 can easily allow the snap-fit ​​connector 355 to snap into the inside of the snap-fit ​​groove 351. At the same time, under the elastic action of the locking spring 354, the locking block 352 can lock the snap-fit ​​connector 355 with the cooperation of the snap-fit ​​groove 351, which facilitates the disassembly and assembly of the first brush plate 33 and the second brush plate 34, thereby facilitating the replacement of worn bristles.

[0031] like Figure 3 As shown, a spiral blade 4 is fixedly sleeved inside the second mounting base 32 and the outer gear ring 22. A flow guide shroud 9 is fixedly sleeved in the middle of the cleaning cylinder 1. The lower end of the flow guide shroud 9 is connected to the upper end of the spiral blade 4, and the upper end of the flow guide shroud 9 is connected to the interior of the cleaning cylinder 1. Due to the arrangement of the spiral blade 4, an upward airflow can be formed around the spiral blade 4 with the cooperation of the flow guide shroud 9, which in turn causes the dust and foreign objects cleaned by the brush bristles below to be sucked into the flow guide shroud 9 and enter the cleaning cylinder 1 with the cooperation of the protective cover 10 and the positioning spring 11. Finally, the dust and foreign objects are retained in the cleaning cylinder 1 with the cooperation of the filter and breathable cover 6.

[0032] A protective cover 10 is provided on the top of the flow guide shroud 9, and a positioning spring 11 is fixedly connected to the bottom of the protective cover 10. The lower end of the positioning spring 11 is fixedly connected to the flow guide shroud 9. Due to the setting of the positioning spring 11, the protective cover 10 can be tightly attached to the top of the flow guide shroud 9 under the pulling action of its elastic restoring force. This can ensure that the airflow inside the flow guide shroud 9 can push up the protective cover 10 so that the airflow and dust can enter the cleaning cylinder 1, while preventing the dust and foreign objects inside the cleaning cylinder 1 from leaking back through the flow guide shroud 9.

[0033] like Figure 3 As shown, a protective cover 8 is fixedly connected inside the cleaning cylinder 1, and a drive motor 24 is fixedly installed inside the protective cover 8. A sealing cover 5 located on the top of the protective cover 8 is threaded onto the top of the inner cavity of the cleaning cylinder 1. Two filter vents 6 are threaded onto the inside of the sealing cover 5, and the two filter vents 6 are respectively connected to the inner and outer sides of the protective cover 8. Due to the setting of the filter vents 6, it can prevent dust and foreign objects sucked into the cleaning cylinder 1 from being discharged to the outside of the cleaning cylinder 1 with the airflow, and can also be used to seal the drive motor 24 inside the protective cover 8 to ensure that the drive motor 24 can dissipate heat in time.

[0034] Working principle and usage process of this utility model:

[0035] When the drive motor 24 is turned on, the transmission gear 23 will rotate continuously through the transmission shaft 25. When the transmission gear 23 rotates, it can drive the inner gear ring 21 and the outer gear ring 22 to rotate in opposite directions simultaneously under the restriction of the rotating retainer 26. Then, with the cooperation of the retaining member 35, the first mounting base 31 and the second mounting base 32 drive the first brush plate 33 and the second brush plate 34 and the brush bristles at the bottom to rotate rapidly and continuously. During this period, the operator controls the lateral movement of the cleaning cylinder 1 as a whole through the handle 7, and then quickly cleans the dried foreign matter with the cooperation of the inner and outer brush bristles rotating in opposite directions.

[0036] Because the rapid rotation of the second mounting base 32 and the second brush plate 34 can drive the spiral blade 4 to rotate rapidly, the airflow below it rises along the guide shroud 9. Then, the dust and foreign objects cleaned from the bottom of the comb can be sucked into the guide shroud 9 by the airflow at the spiral blade 4, and push the protective cover 10 to rise, so that the airflow and dust enter the cleaning cylinder 1. Finally, under the filtering effect of the filter vent 6, the air is discharged to the outside of the cleaning cylinder 1, while the dust and foreign objects are intercepted and stored inside the cleaning cylinder 1. After a period of time, the collected dust and foreign objects can be cleaned by unscrewing the sealing cover 5 or the filter vent 6.
