[0027] like Figures 1 to 8 As shown, the present invention provides a first embodiment of a cleaning machine with a clutch device, which includes a vertical body 1000, a floor brush seat 2000 disposed at the bottom of the vertical body 1000 and movable on a horizontal plane, having a roller brush cavity 2100 and a transmission cavity 2140, a roller brush 2400 disposed in the roller brush cavity 2100, a wastewater tank 3000 disposed on the vertical body 1000, a vacuum motor 4000 located inside the body 1000, generating a vacuum and driving the roller brush 2400 to rotate, a clean water tank 5000 disposed on the vertical body 1000 and above the wastewater tank 3000, a pair of rollers 7000 located at the rear end of the floor brush seat 2000 and capable of rolling and rotating on a horizontal plane, and a clutch device located inside the floor brush seat 2000 and between the vacuum motor 4000 and the roller brush 2400 and selectively driven.

[0028] The vertical body 1000 extends vertically to the horizontal plane and rotates relative to the brush holder 2000. In the first position, the clutch is closed, and the vacuum motor 4000 drives the roller brush 2400 to rotate. In the second position, the clutch is disengaged, and the roller brush 2400 stops rotating. A motor cavity 1200 housing the vacuum motor 4000 is formed inside the bottom of the vertical body 1000. The central axis of the motor cavity 1200 is parallel to the horizontal plane and parallel to the length direction of the vertical body 1000.

[0029] The floor brush holder 2000 is roughly rectangular and moves back and forth on a horizontal plane. It has a length direction and a width direction, with the axis of the roller brush 2400 parallel to the length direction of the floor brush holder 2000. The roller brush cavity 2100 is located in front of the transmission cavity 2140.

The floor brush holder 2000 has a liquid recovery path connected to the wastewater tank 3000 and a liquid spray path connected to the clean water tank 5000.

[0030] The clutch device includes a first drive belt 6200 with one end connected to the output of the vacuum motor 4000, a clutch transmission module 6400 driven to rotate by the first drive belt 6200, a second drive belt 6220 with one end connected to the output of the first drive belt 6200 and the other end connected to the clutch transmission module 6400, a third drive belt 6240 with one end connected to the output of the second drive belt 6220 and the other end connected to the roller brush 2400, and a swing member 6600 that can be touched by the vertical body 1000 and prevent the output of the second drive belt 6220.

[0031] The clutch transmission module 6400 includes a central shaft 6420, a hollow gear component 6440 sleeved on the central shaft 6420, a clutch component 6460 sleeved on the central shaft 6420 and disposed on one side of the gear component 6440 and selectively axially meshing with the gear component 6440, and a pair of bearings 6450 sleeved at both ends of the central shaft 6420 and located outside the gear component 6440 or the clutch component 6460.

[0032] The gear component 6440 includes a transmission tooth portion 6442 with multiple teeth on the outer side, a meshing tooth portion 6444 located on the side of the transmission tooth portion 6442 facing the clutch component 6460 and having a plurality of openings in the radial direction, a gear bearing 6452 sleeved on the central shaft 6420 and located on the other side of the transmission tooth portion 6442, and a retaining ring 6454 sleeved on the central shaft 6422 and axially engaging the gear bearing 6452.

[0033] The clutch 6460 includes a clutch center hole 6461 located therein and allowing the center shaft 6420 to pass through, a pawl 6462 that engages with an opening of the pawl 6444, a blocking disc 6464 that is axially spaced from the pawl 6462 and extends radially, and a receiving portion 6466 located between the pawl 6462 and the blocking disc 6464 and at least partially receiving the swing member 6600.

[0034] The swing member 6600 includes a trigger end 6620 located at one end and in contact with the vertical body 1000, a roller end 6640 located at the other end and partially housed by the housing part 6466, and a swing shaft 6660 located between the trigger end 6620 and the roller end 6640 and allowing the roller end 6640 to rotate relative to each other.

[0035] This utility model provides a second embodiment of a clutch device, which includes a cleaning machine comprising a vertical body 1000, a floor brush seat 2000 disposed at the bottom of the vertical body 1000 and movable on a horizontal plane, having a roller brush cavity 2100 and a transmission cavity 2140, a roller brush 2400 disposed within the roller brush cavity 2100, and a vacuum motor 4000 located within the body 1000, generating a vacuum and driving the roller brush 2400 to rotate. The clutch device includes a central shaft 6420, a hollow gear component 6440 sleeved on the central shaft 6420, and a gear component 6440 sleeved on the central shaft 6420. A clutch 6460 is disposed on one side of the gear 6440 and selectively axially meshes with the gear 6440. The clutch is located between the vacuum motor 4000 and the roller brush 2400 and is selectively driven, having two positions. In the first position, the clutch is closed, the gear 6440 and the clutch 6460 are meshed, and the vacuum motor 4000 drives the roller brush 2400 to rotate. In the second position, the clutch is disengaged, the gear 6440 and the clutch 6460 are separated, and the roller brush 2400 stops rotating.

[0036] The gear component 6440 includes a transmission tooth portion 6442 with multiple teeth on the outer side, a meshing tooth portion 6444 located on the side of the transmission tooth portion 6442 facing the clutch component 6460 and having a plurality of openings in the radial direction, a gear bearing 6452 sleeved on the central shaft 6420 and located on the other side of the transmission tooth portion 6442, and a retaining ring 6454 sleeved on the central shaft 6422 and axially engaging the gear bearing 6452.

[0037] The clutch 6460 includes a clutch center hole 6461 located therein and allowing the center shaft 6420 to pass through, a pawl 6462 that engages with an opening of the pawl 6444, a blocking disc 6464 that is axially spaced from the pawl 6462 and extends radially, and a receiving portion 6466 located between the pawl 6462 and the blocking disc 6464 and at least partially receiving the swing member 6600.

[0038] The swing member 6600 includes a trigger end 6620 located at one end and in contact with the vertical body 1000, a roller end 6640 located at the other end and partially housed by the housing part 6466, and a swing shaft 6660 located between the trigger end 6620 and the roller end 6640 and allowing the roller end 6640 to rotate relative to each other.

[0039] During operation, the vacuum motor 4000 rotates at high speed. The first transmission belt 6200 drives the central shaft 6420 to rotate via the second transmission belt 6220, and then drives the roller brush 2400 to rotate via the third transmission belt 6240. The liquid spray path sprays the cleaning liquid in the clean water tank toward the roller brush 2400, which rotates on the ground, thus cleaning the floor. Due to the vacuum effect of the vacuum motor 4000, the dirty liquid flows into the wastewater tank 3000 through the liquid recovery path. When upright, the vertical body 1000 abuts against the trigger end 6620 at one end, while the roller end 6640, located at the other end and inside the housing 6466, rotates relative to the swing shaft 6660, pushing the blocking disc 6464 to move axially. This causes the clutch 6460 to disengage from the gear 6440, so that the second transmission belt 6220 continues to work, while the third transmission belt 6240 stops driving the roller brush 2400 to rotate, thus achieving upright stopping.

[0040] This invention stops the rotation of the roller brush when the cleaning machine is upright, ensuring reliable cleaning operation.
