DETAILED DESCRIPTION

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0031] Traditional floor scrubbers are usually manually pushed by hand, and their cleaning effect directly depends on the pressure applied by the user to the floor scrubber. However, this operation method causes the brush parts of the floor scrubber to wear out quickly due to long-term excessive pressure, which affects the service life. Therefore, the inventor has proposed the following improvement plan after research, which is described below.

[0032] See also Figure 1-6 The present embodiment provides an integrated floor brush machine gearbox transmission device, including a gearbox 1 and a driving device, wherein a central gear 11 and a plurality of sub-gears 12 are rotatably arranged in the gearbox 1, and the plurality of sub-gears 12 surround and mesh with the central gear 11, and the driving device is arranged on the gearbox 1 and an output shaft 111 of the driving device is connected to the central gear 11; the gearbox 1 also includes a plurality of pins 121, the pins 121 correspond to the sub-gears 12 one by one, and the pins 121 are penetrated through the sub-gears 12, and the upper side wall of the gearbox 1 is provided with a plurality of mounting holes 13 corresponding to the upper ends of the plurality of pins 121, and the lower side wall of the gearbox 1 is provided with a plurality of through holes corresponding to the lower ends of the plurality of pins 121, and an elastic member 2 is arranged in the mounting hole 13, and the upper end of the pin 121 penetrates into the mounting hole 13 and abuts against the elastic member 2, and the lower end of the pin 121 penetrates through the through hole and is connected with a brush member 3.

[0033] It is understandable that in order to improve the overall performance and durability of the floor scrubber, the central gear 11 in the gear box 1 is meshed with the multiple sub-gears 12 through the transmission of the gear box 1. When the driving device is started, the power is transmitted to the central gear 11 through the output shaft 111, thereby driving all the sub-gears 12 to rotate synchronously. The rotation of the sub-gears 12 is transmitted to the brush member 3 through the pin 121, driving the brush member 3 to perform cleaning work, so that the multiple sub-gears 12 drive the multiple brush members 3 to work independently and at the same speed, thereby improving the cleaning efficiency. At the same time, in order to solve the problem of rapid wear of the brush member 3 due to excessive pressure applied by the user in the traditional floor scrubber, the pin 121 is used as a medium to connect the sub-gear 12 and the brush member 3, so that the upper end of the pin 121 is inserted into the mounting hole 13 on the upper side wall of the gear box 1 and counteracts the set elastic member 2. Its function is to provide a certain buffer and adjustment space when the brush member 3 is under pressure, ensuring that the brush member 3 can remain stable and not easily damaged when under force, and at the same time facilitates the adaptive adjustment of the brush member 3 under different ground conditions, and has a stronger cleaning ability for uneven ground. When the drive device is started, the output shaft 111 starts to rotate and drives the central gear 11 to rotate. The rotation of the central gear 11 is transmitted to all the sub-gears 12 through the meshing relationship, so that they rotate synchronously. As the sub-gears 12 rotate, the pin shaft 121 drives the connected brush 3 to rotate. The brush 3 contacts the ground and removes the dirt on the ground through friction. In the process of the brush 3 contacting the ground, due to the uneven ground or the wear of the brush 3, the elastic member 2 at the upper end of the pin shaft 121 will automatically adjust according to the force conditions to ensure that the brush 3 always maintains the appropriate contact force and cleaning effect. It should be explained that the elastic member 2 is always kept in a compressed state, that is, the elastic member 2 always gives the brush 3 a thrust toward the ground.

[0034] Furthermore, in order to cope with different degrees of wear of the brush 3 or different degrees of flatness of the ground, it is necessary to make the brush 3 more adjustable. The present solution also includes an adjusting screw 4. The mounting hole 13 is a through hole. The adjusting screw 4 is screwed into the mounting hole 13. The elastic member 2 is supported between the adjusting screw 4 and the upper end of the pin shaft 121. The adjusting screw 4 of the present embodiment is screwed into the mounting hole 13, and the upper end of the elastic member 2 is pushed to a predetermined position by the locking effect of the thread. By rotating the adjusting screw 4, the depth of the elastic member 2 inserted into the mounting hole 13 can be changed. Since the elastic member 2 is compressed between the adjusting screw 4 and the upper end of the pin shaft 121, the pre-tightening force of the elastic member 2 on the pin shaft 121 can be changed, so that the brush 3 produces different compression amounts on the elastic member 2 when subjected to the same ground reaction force, so that the user can adjust the adjusting screw 4 to adapt to different flatness conditions of the ground and different wear conditions of the brush 3.

[0035] Furthermore, in order to prevent the adjusting screw 4 from loosening or even falling off due to vibration or misoperation during use, the present embodiment also includes an anti-slip device 5, which is axially slidably connected to the mounting hole 13, and the anti-slip device 5 is fixedly connected to the side of the adjusting screw 4 away from the pin shaft 121; an anti-slip groove 131 is circumferentially provided on the side of the mounting hole 13 away from the pin shaft 121, and when the anti-slip device 5 slides to the anti-slip groove 131, it is engaged with the anti-slip groove 131, so that the axial sliding of the anti-slip device 5 in the mounting hole 13 is limited. It should be explained that the anti-slip device 5 is fixed to the adjusting screw 4. Generally, the anti-slip device 5 and the adjusting screw 4 are located together in the mounting hole 13, and are located on the side of the anti-slip groove 131 close to the pin 121. In some working conditions, the adjusting screw 4 and the anti-slip device 5 may be disengaged in the direction of the end of the mounting hole 13 away from the pin 121 without the user's intention. The anti-slip groove 131 is set close to the end of the mounting block away from the pin 121. Therefore, when the anti-slip device 5 moves in the direction away from the pin 121 in the mounting hole 13 to the hole close to the mounting hole 13, the anti-slip device 5 passes through the anti-slip groove 131. At this time, the anti-slip device 5 will cooperate with the anti-slip groove 131 on the wall of the mounting hole 13 to achieve a clamping limit, so that the anti-slip device 5 can no longer slide freely in the axial direction, thereby ensuring the tightening state of the adjusting screw 4. Specifically, the anti-slip groove 131 is an annular groove.

[0036] Specifically, the anti-slip device 5 includes a mounting block, a horizontal sliding hole 51 is radially penetrated on the mounting block, a first horizontal sliding block 511 and a second horizontal sliding block 512 are provided in the horizontal sliding hole 51, and a compression spring 513 is provided between the first horizontal sliding block 511 and the second horizontal sliding block 512; when the anti-slip device 5 slides to the anti-slip groove 131, the first horizontal sliding block 511 and the second horizontal sliding block 512 respectively pop out through the two end openings of the horizontal sliding hole 51 and extend into the anti-slip groove 131. It can be understood that a compression spring 513 is provided between the first horizontal slider 511 and the second horizontal slider 512. When the anti-slip device 5 is in a non-working state (i.e., not sliding into the anti-slip groove 131), the spring is in a compressed state, providing an outward elastic force for the first horizontal slider 511 and the second horizontal slider 512; when the anti-slip device 5 slides to the anti-slip groove 131, the two end openings of the horizontal sliding hole 51 are aligned with the anti-slip groove 131, and the elastic force of the compression spring 513 pushes the first horizontal slider 511 and the second horizontal slider 512 to pop out through the openings and extend into the anti-slip groove 131, respectively, to achieve locking. After locking, the anti-slip device 5 is firmly fixed on the transmission component to ensure the stability and reliability of the transmission process.

[0037] Furthermore, after the anti-slip device 5 is engaged with the anti-slip groove 131, it is also necessary to consider how to restore the anti-slip device 5 and the adjusting screw 4 so that they can resume axial sliding along the mounting hole 13. In this embodiment, a vertical sliding hole 52 is axially opened on the mounting block, and the lower end of the vertical sliding hole 52 is connected to the horizontal sliding hole 51. A vertical sliding block 521 is provided in the vertical sliding hole 52. The upper end of the vertical sliding block 521 extends out of the mounting block, and the lower ends of the vertical sliding block 521 respectively stop at the first horizontal sliding block 511 and the second horizontal sliding block 512. A first wedge structure is provided between the vertical sliding block 521 and the first horizontal sliding block 511, and a second wedge structure is provided between the vertical sliding block 521 and the second horizontal sliding block 512. The sliding of the vertical sliding block 521 is associated with the sliding of the first horizontal sliding block 511 and the second horizontal sliding block 512 through the first wedge structure and the second wedge structure. Specifically, when the vertical slider 521 moves upward, the first horizontal slider 511 and the second horizontal slider 512 are moved away from each other by the compression spring 513, and when the vertical slider 521 moves downward, the first horizontal slider 511 and the second horizontal slider 512 are moved closer to each other by the first wedge structure and the second wedge structure. Through the linkage design of the vertical slider 521 and the first horizontal slider 511 and the second horizontal slider 512, the extension and retraction actions of the first horizontal slider 511 and the second horizontal slider 512 can be precisely controlled, and the overall operation accuracy of the transmission device can be improved. In addition, the design of the vertical slider 521 allows the user to control the synchronous action of the first horizontal slider 511 and the second horizontal slider 512 through a single operation (such as moving the vertical slider 521 up and down).

[0038] Specifically, the first wedge-shaped structure includes a first inclined surface 5211 arranged at the bottom end of the vertical slider 521 and a second inclined surface 5111 arranged at the upper end of the first horizontal slider 511, the first inclined surface 5211 is located on the side of the first horizontal slider 511 away from the second horizontal slider 512, and the first inclined surface 5211 and the second inclined surface 5111 are abutted against each other; the second wedge-shaped structure includes a third inclined surface 5212 arranged at the lower end of the vertical slider 521 and a fourth inclined surface 5121 arranged at the upper end of the second horizontal slider 512, the third inclined surface 5212 is located on the side of the second horizontal slider 512 away from the first horizontal slider 511, and the third inclined surface 5212 and the fourth inclined surface 5121 are abutted against each other; the first inclined surface 5211 and the third inclined surface 5212 are arranged opposite to each other. It can be understood that the first inclined surface 5211 and the second inclined surface 5111, the third inclined surface 5212 and the fourth inclined surface 5121 respectively constitute two pairs of inclined surfaces that abut against each other. When the vertical slider 521 moves in the vertical direction, its inclined surface will produce relative movement with the inclined surfaces of the first horizontal slider 511 and the second horizontal slider 512, thereby pushing or pulling the first horizontal slider 511 and the second horizontal slider 512 to move in the horizontal direction.

[0039] Specifically, the distance between the first inclined surface 5211 and the second inclined surface 5111 gradually decreases in the direction away from the pin shaft 121. When the vertical slider 521 moves downward, the first horizontal slider 511 and the second horizontal slider 512 are squeezed by the first inclined surface 5211 and the third inclined surface 5212 to approach each other; when the vertical slider 521 moves upward, the first horizontal slider 511 and the second horizontal slider 512 are acted upon by the compression spring 513 to move away from each other. It can be understood that during the downward movement of the vertical slider 521, as the vertical slider 521 gradually moves downward, the first inclined surface 5211 gradually approaches and squeezes the second inclined surface 5111, and at the same time, the third inclined surface 5212 also gradually approaches and squeezes the fourth inclined surface 5121. Since the distance between the inclined surfaces gradually decreases in the direction away from the pin shaft 121, this squeezing effect causes the first horizontal slider 511 and the second horizontal slider 512 to approach each other, achieving automatic centering. When the first horizontal slider 511 and the second horizontal slider 512 extend into the anti-slip groove 131, the first horizontal slider 511 and the second horizontal slider 512 can be retracted by pressing the vertical slider 521, so that the anti-slip device 5 and the adjusting screw 4 can continue to move axially.

[0040] Furthermore, a vertical sliding hole 52 is arranged at an eccentric position of the mounting block, and a cross slot 53 is provided at the center position of the upper end of the mounting block. The cross slot 53 is used for a cross screwdriver to be inserted. The design of the cross slot 53 enables a cross screwdriver to be easily inserted and rotated to rotate the mounting block, thereby driving the adjusting screw 4 to penetrate into or withdraw from the mounting hole 13 to change the elastic force of the elastic member 2 on the pin shaft 121.

[0041] Furthermore, the first horizontal slider 511 is located in the horizontal slide hole 51 on the side of the vertical slide hole 52 facing the central axis of the mounting block, and the second horizontal slider 512 is located in the horizontal slide hole 51 on the side of the vertical slide hole 52 away from the central axis of the mounting block, and the radial length of the first horizontal slider 511 is greater than that of the second horizontal slider 512. Furthermore, the brush member 3 includes a rotating block and a plurality of bristles connected to the rotating block, and the rotating block is detachably connected to the bottom end of the pin 121, and the bristles cover the bottom of the gear box 1. The design of the detachably connected rotating block makes the replacement of the bristles and the maintenance of the rotating block simple and quick, reducing the maintenance cost and time.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
