[0032] Please refer to Figures 1-4 , the present utility model provides a technical solution: a gear assembly for synchronous driving of double rolling brushes of a mite remover, including:

[0033] A gear group base 1, on the outer side of which a transmission wheel groove 12 is provided, and a driving wheel groove 11 extends inward from the transmission wheel groove 12. Two positioning structures are provided inside the gear group base 1;

[0034] A base cover 2, which is snap-fitted and fixed to the outer side of the gear group base 1 with bolts;

[0035] A gear group 3, which is arranged between the gear group base 1 and the base cover 2, includes a driving tooth group arranged in the driving wheel groove 11 and a transmission tooth group arranged in the transmission wheel groove 12. The driving tooth group includes a first driving gear 31 and a second driving gear 32 that are meshed and connected. The first driving gear 31 is connected to the output shaft of a motor 4, and the motor 4 is positioned inside the gear group base 1. The transmission tooth group includes a first transmission gear 33 that is integrally arranged in an inner and outer tower shape with the second driving gear 32, and a second transmission gear 34 and a third transmission gear 35 that are sequentially meshed and connected outside the first transmission gear 33. The second driving gear 32, the first transmission gear 33, and the second transmission gear 34 are rotatably sleeved on a rotating shaft 36 of the gear group base 1. The third transmission gear 35 is sleeved and positioned on a gear core shaft 37. The gear core shaft 37 passes through a positioning hole 13 and is inserted into a rotating seat 5. The positioning structure performs rotational limiting on the outer side of the rotating seat 5. The inner side of the rotating seat 5 is snap-fitted with a rolling brush of the mite remover. Among them, based on the design of the number and position of the driving gears and transmission gears, synchronous reverse or forward driving of the third transmission gear 35, the rotating seat 5, and the rolling brush thereon can be achieved.

[0036] The gear assembly of the present utility model drives the double rolling brushes of the mite remover synchronously in opposite or same directions through the driving tooth groups and transmission tooth groups arranged inside and outside and related to each other, ensuring the stability of the transmission of the gear group.

[0037] The driving tooth groups and transmission tooth groups as a whole are in a wave-like structure. This design can offset the extrusion force generated during the meshing rotation between the gears and reduce the lateral dimension of the gear group, ensuring the stable operation of the gear group while reducing the size.

[0038] An arch-shaped hole 351 is provided in the center of the third transmission gear 35, and the insertion block 371 on the outer side of the gear core shaft 37 is inserted and positioned on the arch-shaped hole 351, ensuring the connection strength and the stable torsional transmission between the large-sized gear and the gear core shaft 37.

[0039] The middle part of the gear core shaft 37 is inserted into the positioning hole 13, and a lubricating bearing 38 is arranged between the two. A limiting rib is provided on the side wall of the positioning hole 13 outside the lubricating bearing 38 to reduce the rotation resistance of the gear core shaft 37.

[0040] The inner end of the gear core shaft 37 is clamped and positioned on the outside of the rotating seat 5 through the first clamping rib 372 to ensure the circumferential clamping and positioning strength.

[0041] The positioning structure includes a stepped positioning seat 14 and a limiting ring 15 outside the stepped positioning seat 14. The concave structure 52 on the outside of the rotating seat 5 is sleeved on the stepped positioning seat 14, and the limiting ring 15 is sleeved on the limiting flange 51 outside the concave structure 52. Through the multi-layer rotating limiting structure, the rotation stability of the rotating seat 5 is ensured.

[0042] The inner side of the rotating seat 5 is in a conical structure, and a second clamping rib 53 extends radially on the surface of the conical structure. The end of the second clamping rib 53 is inclined with a buffer inclined plate 54, which can reduce the difficulty of the rotating seat 5 being inserted in place with the rolling brush in alignment, improve the assembly convenience, and buffer the reaction extrusion force formed by the contact and cleaning between the rolling brush and the cleaning surface, reducing the influence on the gear assembly.

[0043] The working principle of the gear assembly for synchronous driving of the double rolling brushes of the mite remover in this embodiment includes: when the gear assembly works, the output shaft of the motor 4 rotates, driving the first driving gear 31 to rotate. Through meshing transmission, the second driving gear 32 and the first transmission gear 33 rotate synchronously, and drive the outer second transmission gear 34 and third transmission gear 35 to rotate along the rotating shaft 36. The gear core shaft 37 rotates together with the third transmission gear 35, and drives the inner rotating seat 5 and the rolling brush clamped thereto to rotate. The extrusion force conducted by the rolling brush can be buffered through the cooperation of the second clamping rib 53 and the buffer inclined plate 54 to reduce its influence on the gear assembly.

[0044] In summary, due to the adoption of the above technical solutions, the gear assembly for synchronous driving of double rolling brushes of a mite remover in this embodiment has the following beneficial effects compared with the prior art:

[0045] The gear assembly of the present utility model drives the double rolling brushes of the mite remover synchronously and in opposite or same directions through the driving tooth sets and transmission tooth sets arranged inside and outside and interconnected, ensuring the stability of the gear set transmission; the driving tooth sets and transmission tooth sets are integrally in a wave-like structure, which can offset the extrusion force generated during the meshing rotation between the gears and reduce the lateral dimension of the gear set, ensuring stable operation of the gear set while reducing the size; the rotating seat and the gear set base are provided with a multi-layer rotating limit structure to ensure the rotation stability of the rotating seat; a second clamping rib and a buffer inclined plate are arranged at the butt joint of the rotating seat and the rolling brush, which can reduce the difficulty of aligning and inserting the rotating seat and the rolling brush, improve the assembly convenience, and buffer the reaction extrusion force formed by the contact cleaning between the rolling brush and the cleaning surface, reducing the influence on the gear assembly.

[0046] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
