[0015] The present invention has positive effects: (1) The wire wheel of the present invention rotates in one direction through the limiting cooperation of the limiting block and the limiting boss and the action of the one-way needle bearing. Since the vibration table and the wire wheel are driven simultaneously by the driving device, when the wire wheel unwinds the first pull rope, the vibration table will vibrate continuously. When the wire wheel and the limiting boss are matched, the wire wheel will continue to slip under the driving rotation, thereby maintaining the unwinding of the rag; the vibration table will continuously vibrate the rag horizontally through the second pull rope, thereby simulating the horizontal wiping of stains by human hands, achieving a better cleaning effect on the stains.

[0016] (2) The middle part of the output shaft of the driving device of the utility model drives the wire wheel through the transmission component to reel or unreel the first pull rope, thereby driving the rag to perform vertical lifting and lowering movements; a limit block is fixedly provided on the wire wheel, and a limit boss is fixedly provided on both sides of the base, which can form a limit fit with the limit block; the wire wheel is limited in rotation under the limit fit of the limit boss and the limit block, so that the wire wheel can reel and unreel the first pull rope to a fixed length by using the one-way needle bearing, thereby retracting the rag.

[0017] (3) A rotating sleeve is fixed on the top of the output shaft of the driving device of the present invention, and a connecting rod extending along the extension direction of the output shaft of the driving device is fixed on the rotating sleeve. The connecting rod is eccentrically arranged, and the vibration table drives the rotating sleeve to rotate through the driving device, thereby driving the vibration table to rotate eccentrically; under the action of the eccentric rotation, the vibration table can pull the second pull rope to drive the rag to vibrate horizontally, and at the same time, the first pull rope always keeps pulling the rag in the opposite direction to the pulling direction of the second pull rope, so that the rag can simulate the human hand to wipe the stain back and forth horizontally.

[0018] (4) The transmission assembly of the present invention includes a first gear, a second gear, a third gear and a fourth gear that can form meshing transmission cooperation with each other in sequence.

[0019] (5) The vibration table of the present invention is rotatably arranged on the connecting rod through the connecting bearing, and the second pull rope can rotate along with the rotation of the vibration table and will not be entangled on the vibration table.

[0020] (6) The first pull rope of the utility model is detachably fixed to the spool by the snap-fitting of the fixing block and the slot; at the same time, the second pull rope is fixed to one end of the vibration table and is wound around the bolt and fixed to the vibration table by the threaded fitting of the bolt and the screw hole, or the second pull rope is fixed to one end of the vibration table and is fixed to the end of the connecting plate away from the vibration table; both the first pull rope and the second pull rope can be replaced after being worn out during use, so as to ensure the normal use of the first pull rope and the second pull rope.

The vibrating table 3 is rotatably arranged on the connecting rod 63 through the connecting bearing 64. The vibrating table 3 is rotatably arranged on the connecting rod 63 through the connecting bearing 64. The vibrating table 3 is rotatably arranged on the connecting rod 63 through the connecting bearing 64. The vibrating table 3 is driven by the driving device 6 to rotate the rotating sleeve 62, thereby driving the vibrating table 3 to perform eccentric rotation.

[0035] Since the vibration table 3 and the wire wheel 2 are driven simultaneously by the driving device 6, when the wire wheel 2 unwinds the first pull rope 4, the vibration table 3 will vibrate continuously. When the wire wheel 2 cooperates with the limiting boss 11, the wire wheel 2 will continue to slip under the driving rotation, thereby maintaining the unwinding of the rag; the vibration table 3 will continuously vibrate the rag horizontally through the second pull rope 5, thereby simulating the horizontal wiping of stains by human hands, achieving a better cleaning effect on the stains.

[0036] The rotation of the line wheel 2 is limited by the limiting cooperation between the limiting protrusion and the limiting block 21, so that the one-way needle bearing 8 is used to achieve one-way slippage with the fixed rod 76, and the line wheel 2 can unwind the first pull rope 4 to a fixed length.

[0037] A one-way needle roller bearing 8 is sleeved on the output end of the transmission assembly 7, and the spool 2 is sleeved on the one-way needle roller bearing 8. A limit block 21 is fixedly provided on the spool 2, and a limit boss 11 is fixedly provided on the base 1, which can form a limit fit with the limit block 21 on both sides. The spool 2 is unidirectionally rotated on the base 1 through the limit fit between the limit block 21 and the limit boss 11 and the action of the one-way needle roller bearing 8.

[0038] The one-way needle roller bearing 8 can also be replaced with a ratchet structure.

[0039] Under the action of eccentric rotation, the vibration table 3 can pull the second pull rope 5 to drive the rag to vibrate horizontally. At the same time, the first pull rope 4 always keeps pulling the rag in the opposite direction to the second pull rope 5, so that the rag can simulate human hands to wipe the stains horizontally back and forth.

[0040] The transmission assembly 7 includes a first gear 71, a second gear 72, a third gear 73 and a fourth gear 74 which can form meshing transmission cooperation with each other in sequence.

The center is rotatably connected to a support rod 75, which is fixedly arranged inside the base 1; the end of the fixed rod 76 that is not connected to the rotating seat extends out of the base 1, and the one-way needle bearing 8 is sleeved on the end of the fixed rod 76 extending out of the base 1. The spool 2 is unidirectionally rotated on the fixed rod 76 through the limiting cooperation of the limiting block 21 and the limiting boss 11 and the action of the one-way needle bearing 8. The spool 2 is driven by the driving device 6 and the unidirectional rotation of the spool 2 to reel or unreel the first pull rope 4, thereby driving the rag to perform vertical lifting and lowering movements.

[0041] By reducing the speed of each gear, the rotation speed of the vibration table 3 directly connected to the driving device 6 is faster than the rotation speed of the wire wheel 2. Based on this, while reducing the rotation speed of the wire wheel 2 so that the friction between the wire wheel 2 and the one-way needle bearing 8 is reduced, it can also ensure that the vibration table 3 maintains its original vibration frequency, thereby ensuring the cleaning effect.

[0042] The spool 2 is provided with a first guide groove 22 and a second guide groove 23 which are arranged in an upper and lower manner and are both arranged along the rotation direction of the spool 2.

A fixed block 25 which can be inserted into the card slot 24 to form a snap fit is also provided. One end of the first pull rope 4 fixedly provided on the spool 2 is fixedly provided on the fixed block 25. The first pull rope 4 is detachably fixed on the spool 2 through the snap fit between the fixed block 25 and the card slot 24.

[0043] The vibration table 3 is provided with a plurality of screw holes, each of which is equipped with a bolt. One end of the second pull rope 5 is fixedly arranged on the vibration table 3 and is wound around the bolt and then fixed to the vibration table 3 through the threaded fit between the bolt and the screw hole.

[0044] A guide block 12 is fixedly provided on the base 1 for guiding the first pull rope 4 when winding or unwinding. A guide groove is provided on the guide block 12. A guide member 121 is provided in the guide groove for guiding the first pull rope 4. A hole is penetrated in the middle of the guide member 121 for the first pull rope 4 to pass through. The first pull rope 4 is directionally extended and retracted under the guidance of the guide member 121, thereby reducing the wear of the first pull rope 4 during use.

[0045] A ball bearing 621 is fixed on the outer wall of the rotating sleeve 62 . The outer wall of the ball bearing 621 acts on the base 1 , and the rotating sleeve 62 rotates with the base 1 through the ball bearing 621 .

[0046] The fixed rod 76 is rotatably arranged on one end of the rotating seat and is fixedly provided with a first oil-containing bearing 761, and the part of the fixed rod 76 that contacts the base 1 is fixedly provided with a second oil-containing bearing 762; the outer wall of the first oil-containing bearing 761 acts on the rotating seat, and the outer wall of the second oil-containing bearing 762 acts on the base 1.

[0047] The wire wheel 2 and the vibration table 3 are located on both sides of the base 1. The wire wheel 2 and the vibration table 3 are located at two positions. The length required for the first pull rope 4 to reach the position of the second wire wheel 2 is longer, which can provide a longer buffer.

[0048] The driving device 6 mentioned above adopts a brushless DC external motor.

[0049] (Example 2)

[0050] See Figure 8 In the present invention, a connecting plate is fixedly connected to the vibration table 3, and a second pull rope 5 is fixedly arranged on one end of the vibration table 3 and on the end of the connecting plate away from the vibration table 3; the second pull rope 5 is fixed to the end of the connecting plate away from the vibration table 3 by bolts.

[0051] The vibration frequency of the second pull rope 5 pulling the rag can be increased by the connecting plate.

[0052] The remaining technical features are consistent with those of Example 1.

[0053] The working principle of the utility model is as follows: the brushless DC external transmission motor drives the gear to rotate, the gear drives the output shaft 61 to rotate, the output shaft 61 drives the one-way needle bearing 8 to rotate, the one-way needle bearing 8 drives the wire wheel 2 to rotate, the wire wheel 2 is connected to the rag, so that the rag performs an up and down reciprocating motion; at the same time, the output shaft 61 of the motor drives the vibration table 3 to rotate eccentrically through the rotating sleeve 62, forming vibration, and the vibration table 3 is connected to the rag to vibrate in the horizontal direction.

[0054] The brushless DC external motor drives the fixed rod 76 to rotate through the transmission component 7. The rotated fixed rod 76 drives the one-way needle bearing 8 to rotate under the action of friction. The rotating one-way needle bearing 8 drives the spool 2 to rotate clockwise. At this time, the rag drops and reaches the specified height after running for a period of time. In actual use, it is the height that contacts the ground. At this time, the spool 2 contacts and limits one side of the limiting boss 11. Under the action of the limit, the spool 2 rotates with the one-way needle bearing 8, and the spool 2 continues to slip, and the rag maintains the height after it drops. At the same time, the brushless DC external motor The output end drives the rotating sleeve 62 and the connecting rod 63 to rotate synchronously. The rotating sleeve 62 is provided with a vibration table 3 on the connecting rod 63 as it vibrates, and the vibration table 3 drives the rag to move toward one side. The rag is pulled to the other side by the first pull rope 4. The rag pulled by the first pull rope 4 drives the vibration table 3 and the connecting rod 63 to rotate. The vibration table 3 returns to the position before rotation under the rotation of the brushless DC outgoing motor, and so on. The vibration table 3 drives the rag to vibrate continuously. During this process, the rag remains stable under the joint tension of the first pull rope 4 and the second pull rope 5.

[0055] The brushless DC external motor drives the fixed rod 76 to rotate through the transmission component 7. The rotated fixed rod 76 drives the one-way needle bearing 8 to rotate under the action of the one-way needle bearing 8. The rotating one-way needle bearing 8 drives the wire wheel 2 to rotate counterclockwise. At this time, the rag is lifted up and rises. After running for a distance, it contacts and limits the other side of the limit boss 11. The wire wheel 2 is blocked and the motor is blocked at the same time. The brushless DC external motor stall protection function is triggered, the brushless DC external motor stops working immediately, and the entire mechanism stops running.
