Description

Technical Field

[0001] The utility model relates to the technical field of roller brushes for floor scrubbers, in particular to a roller brush assembly for floor scrubbers. Background Art

[0002] A floor brush machine usually includes a floor brush machine body and a floor brush. The floor brush machine body is provided with a water tank and a sewage tank. The water tank cooperates with a liquid spraying device to spray water to the roller of the floor brush. The sewage tank is connected to a suction device to suck sewage. The roller of the floor brush is driven to rotate by a motor. During the rotation of the roller, the liquid spraying device sprays water and the suction device sucks synchronously to complete the floor washing. The roller of the floor brush machine in the prior art is usually arranged in a manner that both ends are connected to the floor brush machine body.

[0003] For example, the Chinese patent document with the authorization announcement number CN219742617U disclosed an efficient floor brush structure of a floor scrubber on September 26, 2023, including a floor brush body and an articulated seat connected to the main unit. The front end of the floor brush body is provided with a roller brush bin for installing a floor scrubbing roller brush. The floor scrubbing roller brush contacts the ground through the bottom opening of the roller brush bin, and a suction port and a scraper strip are provided on the back wall of the roller brush bin. The floor scrubbing roller brush is rotatably connected at both ends in the roller brush bin.

[0004] The disadvantage of the prior art is that the fixed structures at both ends of the floor scrubbing roller brush need to be removed first when disassembling for cleaning or maintenance, and the end structures are usually fixed on the floor brush body, so that there are many related parts to be removed, which is inconvenient to operate. In addition, due to the setting of the end fixed structure, in locations such as corners, due to the obstruction of the fixed structure, the cleaning ability of the end of the floor scrubbing roller brush is poor, and sanitary dead corners are easily formed.

The pressure transmitted by the connecting rod is stably transmitted to the rotating shaft where the roller brush is located through the casing. The three segments of the casing are parallel or perpendicular to each other, and the size control and angle control are easy to achieve, which is convenient for manufacturing. Since the rotating shaft is parallel to the second segment, when the rotating shaft is assembled with the casing, the second segment can be used as a calibration to ensure the assembly accuracy of the rotating shaft.

[0012] Preferably, the transmission assembly includes a first gear shaft, a second gear shaft, a first pulley and a second pulley, the first gear shaft and the second gear shaft are driven by a bevel gear set, the first pulley is arranged on the second gear shaft and rotates synchronously with the second gear shaft, the first pulley and the second pulley are synchronously driven by a belt, the second pulley is arranged on the rotating shaft and rotates synchronously with the rotating shaft, the first gear shaft is arranged in the first segment, the second gear shaft is arranged in the second segment, and the first pulley, the second pulley and the belt are arranged in the third segment.

[0031] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0032] In the description of this embodiment, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore, cannot be understood as a limitation on the utility model. In addition, if the terms "first", "second", and "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0033] like Figures 1 to 6As shown, a floor brush machine roller brush assembly proposed in one embodiment of the utility model includes a connecting rod 1, a housing 4, a rotating shaft 31 and a roller brush 32. One end of the connecting rod 1 is inserted into the housing 4. A transmission rod 2 driven to rotate by a driving element is provided in the connecting rod 1. A transmission assembly connected to the transmission rod 2 is provided in the housing 4. The transmission rod 2 drives the rotating shaft 31 to rotate through the transmission assembly. The roller brush 32 is coaxially connected to the rotating shaft 31. One end of the rotating shaft 31 is rotatably connected to the housing 4. The other end of the rotating shaft 31 is suspended to form a free end. The roller brush 32 is sleeved on the rotating shaft 31 from the free end of the rotating shaft 31 and is relatively locked with the rotating shaft 31. A plurality of bristle groups 33 are provided on the periphery of the roller brush 32. When the roller brush 32 rotates, the bristle groups 33 scrub the floor.

[0034] The floor brush machine used in this embodiment includes a floor brush machine body, and a water tank, a water pump, a driving motor, a suction device and a sewage tank are arranged in the floor brush machine body. The sewage tank is connected to the suction device to complete the extraction of sewage after cleaning. The water tank delivers water to the cleaning area of ​​the floor brush machine through the water pump, and the driving motor provides power for the rotation of the floor brush. The floor brush machine roller brush 32 structure of the present application is arranged below the floor brush machine body, and the driving motor drives the transmission rod 2 to rotate around the axis of the transmission rod 2 in a direct connection or gear transmission manner. The floor brush machine roller brush 32 structure can be directly combined with the existing floor brush machine body. Since the floor brush machine is a mature prior art, and this application does not involve the improvement of the floor brush machine body, the specific structure of the floor brush machine will not be repeated in conjunction with the drawings.

[0035] After one end of the connecting rod 1 is inserted into the housing 4, the housing 4 and the outer periphery of the connecting rod 1 are interferingly matched to achieve a tight fixation. Figure 2 In the example shown, the housing 4 is a two-half structure, and the two halves of the housing 4 are fastened by bolts after being fastened together, thereby holding the connecting rod 1 tightly.

[0036] As a simple replacement for the above solution, the connecting rod 1 and the housing 4 are directly fastened by bolts.

[0037] The transmission assembly is used to transmit the rotational power of the transmission rod 2 to the rotation shaft 31 to realize the rotation of the rotation shaft 31 .

[0038] The roller brush 32 of the present embodiment is assembled in the floor brush machine by being inserted into the rotating shaft 31. One end of the roller brush 32 is not fixed to the housing 4. The roller brush 32 can be directly removed from the floor brush machine without disassembling the housing 4 and the transmission assembly. The disassembly efficiency of the roller brush 32 is high, thereby improving the efficiency of cleaning and maintenance of the roller brush 32. There is no fixed structure blocking the end of the roller brush 32 corresponding to the free end of the rotating shaft 31, so the cleaning ability of the end of the roller brush 32 is improved, which can improve the cleaning efficiency of the roller brush 32.

[0039] In order to improve the reliability of the assembly of the rotating shaft 31 and the roller brush 32, reduce the size of the rotating shaft 31, and avoid excessive bending moment caused by the cantilever structure of the rotating shaft 31, one embodiment of the utility model proposes a roller brush 32 structure of a floor brush machine, wherein a mounting sleeve 35 is provided on the rotating shaft 31, and the rotating shaft 31 is made of metal to ensure the service life. The mounting sleeve 35 is made of a lightweight material such as plastic, which not only ensures the reliability of the synchronous transmission between the roller brush 32 and the rotating shaft 31, but also reduces the bending moment of the rotating shaft 31. The mounting sleeve 35 is sleeved outside the rotating shaft 31 and connected to the radial direction of the two by a pin shaft to achieve locking, so as to complete the fixed connection between the mounting sleeve 35 and the rotating shaft 31. A limiting ring 36 is provided on the mounting sleeve 35, and the limiting ring 36 and the mounting sleeve 35 are an integral structure, and the limiting ring 36 protrudes outward from the outer periphery of the mounting sleeve 35. The limiting ring 36 is located at one end of the mounting sleeve 35 facing the third segment 7. A through mounting hole 38 is provided inside the roller brush 32 at its axial position. One end of the roller brush 32 is sleeved outside the mounting sleeve 35 and abuts against the limit ring 36. The mounting hole 38 contacts the outer periphery of the mounting sleeve 35. A knob 39 is provided at the other end of the roller brush 32. The knob 39 is connected to the end of the mounting sleeve 35. The mounting sleeve 35 is provided with a tightening table 37 at the outer periphery of one end close to the limit ring 36. The tightening table 37 is a round table. When the knob 39 is connected and locked with the mounting sleeve 35, one end of the roller brush 32 is gradually squeezed and tightened with the tightening table 37, thereby preventing the roller brush 32 from moving radially relative to the mounting sleeve 35. The housing 4 is provided with a through hole for the mounting sleeve 35 to pass through. The knob 39 includes an operating portion 40 and a connecting ring 41. The connecting ring 41 is snap-connected with the mounting sleeve 35.

[0040] As a simple replacement for the above solution, the inner periphery of the connecting ring 41 and the outer periphery of one end of the mounting sleeve 35 are locked by threads.

[0041] As a simple replacement for the above solution, the connecting ring 41 and the mounting sleeve 35 are fixed by snap-fitting.

[0042] In order to further improve the cleaning ability of the end of the roller brush 32, as Figure 1 and Figure 2 As shown, one embodiment of the utility model proposes a floor brush machine roller brush 32 structure, the outer periphery of one end of the roller brush 32 with a knob 39 is provided with a truncated cone with a cone angle facing outward, and an end bristle group 34 is provided on the truncated cone, and the end bristle group 34 is perpendicular to the generatrix of the truncated cone where it is located. The end bristle group 34 improves the cleaning ability of the roller brush 32 to the sanitary dead corner.

[0043] One embodiment of the present utility model provides a floor brush machine roller brush 32 structure, such as Figure 1 and Figure 2As shown, the housing 4 includes a first segment 5 for connecting to the connecting rod 1, the first segment 5 is opposite to the side of the roller brush 32, and a water pipe for delivering water to the outside of the roller brush 32 is integrated in the first segment 5. The housing 4 also includes a second segment 6 and a third segment 7. The first segment 5, the second segment 6 and the third segment 7 are a continuous integral structure. The second segment 6 vertically connects the first segment 5 and the third segment 7, and a transition fillet is provided between two adjacent segments. The rotating shaft 31 is rotatably connected to the third segment 7, the third segment 7 is parallel to the first segment 5, and the rotating shaft 31 is parallel to the second segment 6.

[0044] In order to match the structure of the housing 4, Figure 2 As shown, the transmission assembly includes a first gear shaft 8, a second gear shaft 9, a first pulley 11 and a second pulley 12. The first gear shaft 8 and the second gear shaft 9 are driven by a bevel gear set 10. The first gear shaft 8 and the second gear shaft 9 are arranged vertically. The first pulley 11 is arranged on the second gear shaft 9 and rotates synchronously with the second gear shaft 9. The first pulley 11 and the second pulley 12 are synchronously driven by a belt 13. The second pulley 12 is arranged on the rotating shaft 31 and rotates synchronously with the rotating shaft 31. The first gear shaft 8 is arranged in the first segment 5, the second gear shaft 9 is arranged in the second segment 6, and the first pulley 11, the second pulley 12 and the belt 13 are arranged in the third segment 7. Figure 2 It can be seen that the first section 5 is provided with a first bearing 14 that matches the first gear shaft 8, the second section 6 is provided with two second bearings 15 that match the two ends of the second gear shaft 9, and the third section 7 is provided with two third bearings 16 that are arranged at intervals to match the rotating shaft 31. Figure 4 and Figure 5 It can be seen that the first bracket 17 is fixed in the first segment 5 and the second segment 6 respectively. Since the housing 4 is a two-half structure, the first segment 5, the second segment 6 and the third segment 7 are symmetrically separated by the plane formed by the axes of the three to form a two-half structure spliced ​​together. When the two-half housing 4 is assembled, the first bracket 17 is also assembled and formed, and a cylindrical groove for mounting a bearing is formed inside the first bracket 17. Figure 2It can be seen that the third segment 7 is provided with a second bracket 18, the third bearing 16 is arranged in the second bracket 18, and the second bracket 18 is fixed to the housing 4 by bolts. When the rotating shaft 31 is assembled, the second bracket 18, the third bearing 16, the rotating shaft 31 and the belt 13 can be pre-installed as an integral structure, and then the second bracket 18 is fixed to the third segment 7, so that the rotating shaft 31 in the third segment 7 can be completed. Then, the pulley on the second gear shaft 9 is matched with the belt 13, and the second gear shaft 9 and the first gear shaft 8 are completed in sequence. Finally, the two halves of the housing are spliced ​​and fixed, and the arrangement of the internal transmission assembly is completed. The assembly method is reliable, especially the installation of the rotating shaft 31 is positioned and adjusted by the second bracket 18, and the force of the rotating shaft 31 will not be directly transmitted to the housing 4. The force of the rotating shaft 31 can be buffered by the second bracket 18, thereby improving the structural reliability of the third segment 7.

[0045] It is understandable that when the structure of the housing 4 is modified, the transmission assembly can also be reassembled to match the structure of the housing 4 by conventional transmission components such as a gear set, a pulley set, a connecting rod assembly, etc.

[0046] In the above embodiment, a water pipe is also integrated in the connecting rod 1, and the first section 5 is also provided with a water pipe. The water pipe in the connecting rod 1 is defined as the first water pipe 3, and the water pipe in the first section 5 is the second water pipe 19. The first water pipe 3 and the second water pipe 19 are connected to supply water when the roller brush 32 is washing the floor. Figure 4 and Figure 6 As shown, the connecting rod 1 is hollow inside, the water pipe is located on one side inside the connecting rod 1, and the transmission rod 2 is located on the axis of the connecting rod 1. In order to prevent the water pipe from interfering with the transmission assembly, a buckle 20 for limiting the second water pipe 19 is provided in the first section 5 to prevent the water pipe from interfering with the transmission assembly. Figure 4 As shown, the buckle 20 is an "L"-shaped folding plate structure, and one end of the buckle 20 is separated from the housing 4 to form an opening, and the water pipe can be inserted into the buckle 20 from the opening for limiting.

[0047] Furthermore, in Figure 5 In the scheme shown, a water channel joint 21 is provided in the first section 5. The water channel joint 21 is linearly conductive and is used to connect the first water pipe 3 and the second water pipe 19. Through the connection of the water channel joint 21, the direct effect of the stress at the junction of the connecting pipe and the first section 5 on the water pipe can be reduced, thereby ensuring the stability of the water channel.

[0048] One embodiment of the present utility model provides a floor brush machine roller brush 32 structure, such as Figure 2As shown, the housing 4 is connected to a shield 22 that blocks between the second segment 6 and the roller brush 32. The shield 22 can prevent the dirty water splashed by the roller brush 32 from splashing onto people. A water distribution chamber 25 connected to the water pipe is provided in the shield 22, and a nozzle 26 connecting the inside of the water distribution chamber 25 and the outside of the shield 22 is provided on the shield 22. A joint 27 is fixedly provided between the second segment 6 and the shield 22. One end of the shield 22 is fixedly connected to the third segment 7. The joint 27 connects the water pipe and the water distribution chamber 25. Figure 2 In the scheme shown, the shield 22 includes a first shield 23 and a second shield 24. The first shield 23 is located outside the second shield 24, and the first shield 23 and the second shield 24 are fixed by screws. A water distribution chamber 25 is formed between the first shield 23 and the second shield 24. One end of the first shield 23 is fixed to the third segment 7, and the outside of the first shield 23 is fixed to the joint 27. The joint 27 is fixed to the second segment 6. A water distribution pipe 28 is arranged in the water distribution chamber 25. The arrangement of the second shield 24 can prevent the water distribution pipe 28 and the joint 27 from being soiled by the sewage splashed by the roller brush 32. The joint 27 is a three-way structure including an inlet and two outlets. Two nozzles 26 are provided. The two nozzles 26 are connected to one outlet of the joint 27 through the water distribution pipe 28 respectively. The inlet of the joint 27 is connected to the second water pipe 19. The inlet of the joint 27 is coaxially arranged with the connecting rod 1. The joint 27 corresponds to the middle position of the axial direction of the roller brush 32. The two nozzles 26 are symmetrically arranged on both sides of the inlet of the joint 27. The nozzle 26 corresponds to a position near the axial trisection of the roller brush 32 , and can spray water on the roller brush 32 more evenly.

[0049] As a simple replacement for the above solution, the water distribution chamber 25 is designed as a sealed chamber, and the nozzle 26 is directly connected to the water distribution chamber 25. Thus, a plurality of nozzles 26 can be provided to obtain a more uniform water distribution effect. However, this solution requires controlling the sealing of the water distribution chamber 25, and the application cost is relatively high.

[0050] One embodiment of the present invention provides a floor brush machine roller brush 32 structure, the outer end of the shield 22 is provided with a convex side brush 29. Figure 2 and Figure 3 As shown, the side brush 29 is arranged on the first shield 23, and a convex rib 30 is arranged at one end of the side brush 29, and the convex rib 30 protrudes from both sides of the side brush 29. The first shield 23 is provided with a limiting groove corresponding to the convex rib 30, and the convex rib 30 is inserted into the limiting groove and fixed to realize the connection between the first shield 23 and the side brush 29. The side brush 29 is made of soft material such as rubber and can be flattened. When cleaning the corners, the side brush 29 can clean the stains at the bottom of the wall or pillars, further improving the cleaning ability of the floor brush machine.
