[0025] Preferably, a filling port communicating with the water cavity is provided on the top of the storage box, and a rubber plug is provided in the filling port.

[0026] A method for using a floor scrubber with an oil removal function comprises the following steps:

[0027] S1. Start the rear motor to drive roller A to rotate clockwise, thereby pushing the entire device to move on the ground. During this process, start the front motor to rotate roller B, thereby driving the cloth cover to rotate clockwise. Use the cloth cover to wipe the garbage and stains on the ground, and then push them into the front slot into the garbage chamber. The liquid pump can be started to spray water in the water chamber onto the cloth cover to improve the cleaning ability.

[0028] S2. As drum B rotates, the rope on its surface moves synchronously. When the rope falls to the ground from the front, the inner shaft and the disc on its surface remain fixed, and the pin and gear that follow the circular motion of drum B move to the lower area. The gear and pin are driven to rotate clockwise along the tooth surface of the left disc. In particular, the rope is pressed between the cloth cover and the ground, and the two ropes on the outer ends of the pin are twisted together, thereby twisting condensed oil stains, hair and other dirt on the ground into the two ropes and pulling them off the ground as drum B rotates.

[0029] S3. After cleaning the floor, the twisted rope is transferred to the front trough. The pin and gear that follow the circular motion of roller B move to the upper area. The gear and pin are driven to rotate counterclockwise along the tooth surface of the right disc, twisting the twisted rope back and loosening it, thereby shaking off the trapped dirt into the front trough and dialing it into the garbage cavity. During this process, the auxiliary roller located on the upper side of the inner trough squeezes the continuously rotating cloth cover to remove water, preventing the sewage from being brought to the subsequent floor. The rake function of the auxiliary roller can rake and comb the ropes neatly and scrape off the dirt in the ropes.

[0030] S4. When the machine is moved or passed through a carpet without the need for floor cleaning, the operator can detent the buckle to disengage it from the bayonet to unlock the inner shaft, then rotate the inner shaft counterclockwise and unscrew the auxiliary roller from the inner groove through the bracket, so that the auxiliary roller replaces roller B and touches the ground. Then release the buckle to lock the inner shaft and the auxiliary roller. At this time, the machine can use roller A and the auxiliary roller to move quickly.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] In the present invention, the rope on its surface is driven by the roller B to follow the synchronous movement. When the rope falls to the ground from the front side, since the inner shaft and the disk on its surface remain fixed, the pin and gear that follow the circular motion of the roller B move to the lower area, and the gear and the pin can be driven to rotate clockwise along the tooth surface on the left disk. In particular, the rope is pressed between the cloth cover and the ground, and the two ropes on the outer ends of the pin are twisted with each other, so that the condensed oil stains or hair and other dirt on the ground are twisted into the two ropes and pulled away from the ground as the roller B rotates. Compared with common friction cleaning, the connection between the cleaning component and the dirt is more firm, so that the overall equipment has a better adhesion and removal effect for condensed oil stains or hair.

[0033] In the present invention, the twisted rope after cleaning the floor is transferred into the front groove, and the pin shaft and gear that follow the circular motion of the roller B move to the upper area, and the gear and the pin shaft can be driven to rotate counterclockwise along the tooth surface on the right disc, twisting the twisted rope back and loosening it, and shaking off the entangled dirt into the front groove. During this process, the auxiliary roller located on the upper side of the inner groove squeezes and removes water from the continuously rotating cloth cover to prevent sewage from being brought to the subsequent floor, and the rake operation on the auxiliary roller can rake and comb each rope neatly and scrape off the dirt in the rope. On the one hand, it can effectively self-clean the cloth cover and the rope, and on the other hand, it can prevent the rope from being entangled, which is convenient for the equipment to perform continuous floor cleaning.

[0034] In the present invention, the buckle is pulled to disengage it from the bayonet to unlock the inner shaft, and then the inner shaft is rotated counterclockwise to rotate the auxiliary roller out of the inner groove through the bracket, so that the auxiliary roller replaces roller B and touches the ground, and the buckle is released to lock the inner shaft and the auxiliary roller. At this time, the equipment can use roller A and the auxiliary roller to move quickly without being affected by roller B, the cloth cover and the twisted rope, and has better flexibility of use.

[0069] A method for using a floor scrubber with an oil removal function comprises the following steps:

[0070] S1. Start the rear motor 5 to drive the roller A4 to rotate clockwise, thereby pushing the entire device to move on the ground. During this process, start the roller B63 of the front motor 5 to rotate, thereby driving the cloth cover 64 to rotate clockwise. The cloth cover 64 is used to wipe the garbage and stains on the ground, and then transfer them into the front groove 61 and guide them into the garbage chamber 67-2. The liquid pump 610 can be started to spray the water in the water chamber 67-1 onto the cloth cover 64 to improve the cleaning ability.

[0071] S2. As roller B63 rotates, the rope 653 on its surface moves synchronously. When the rope 653 falls to the ground from the front, the inner shaft 62 and the disc 654 on its surface remain fixed, and the pin 652 and the gear 656 that follow the circular motion of roller B63 move to the lower area. The gear 656 and the pin 652 can be driven to rotate clockwise along the tooth surface 655 on the left disc 654. In particular, the rope 653 is pressed between the cloth cover 64 and the ground, and the two ropes 653 on the outer ends of the pin 652 are twisted together, thereby twisting the condensed oil stains, hair and other dirt on the ground into the two ropes 653 and pulling them off the ground as roller B63 rotates.

[0072] S3. After cleaning the floor, the rope 653 is transferred into the front groove 61. The pin 652 and the gear 656 that follow the circular motion of the roller B63 move to the upper area. The gear 656 and the pin 652 can be driven to rotate counterclockwise along the tooth surface 655 on the right disk 654, twisting the rope 653 in a twisted state back and loosening it, thereby shaking off the trapped dirt into the front groove 61 and dialing it into the garbage cavity 67-2. During this process, the auxiliary roller 6577 located on the upper side of the inner groove squeezes and removes water from the continuously rotating cloth cover 64 to prevent the sewage from being brought to the subsequent floor. The rake operation on the auxiliary roller 6577 can rake and comb each rope 653 and scrape off the dirt in the rope 653.

[0073] S4. When the machine is moved or passed through the carpet without the need for floor cleaning, the operator can detent the buckle 6573 to disengage it from the bayonet 6574 to unlock the inner shaft 62, then rotate the inner shaft 62 counterclockwise and unscrew the auxiliary roller 6577 from the inner groove through the bracket 6576, so that the auxiliary roller 6577 replaces the roller B63 and touches the ground, and release the buckle 6573 to lock the inner shaft 62 and the auxiliary roller 6577. At this time, the device can use the roller A4 and the auxiliary roller 6577 to move quickly.

7. A method for using a floor scrubber with a degreasing function according to claim 6, comprising the following steps: S1. Start the rear motor (5) to drive the roller A (4) to rotate clockwise, thereby pushing the entire device to move on the ground. During this process, start the roller B (63) of the front motor (5) to rotate, thereby driving the cloth cover (64) to rotate clockwise, and use the cloth cover (64) to wipe the garbage and stains on the ground, and insert them into the front groove (61) into the garbage cavity (67-2), and start the liquid pump (610) to spray the water in the water cavity (67-1) onto the cloth cover (64), thereby improving the cleaning ability; S2. During the rotation of the roller B (63), the rope (653) on its surface follows the synchronous movement. When the rope (653) falls to the ground from the front side, since the inner shaft (62) and the disc (654) on its surface remain fixed, the pin (652) and the gear (656) that follow the roller B (63) in the circular motion move to the lower area. The gear (656) and the pin (652) can be driven to rotate clockwise along the tooth surface (655) on the left disc (654). In particular, the rope (653) is pressed between the cloth cover (64) and the ground. The two ropes (653) on the outer end of the pin (652) are twisted with each other, so that the dirt such as oil stains or hair condensed on the ground is twisted into the two ropes (653) and pulled away from the ground as the roller B (63) rotates. S3, after cleaning the ground, the rope (653) is transferred into the front groove (61), and the pin (652) and the gear (656) that follow the circular motion of the roller B (63) move to the upper area, and the gear (656) and the pin (652) can be driven to rotate counterclockwise along the tooth surface (655) on the right disc (654), twisting the rope (653) in the twisted state back and loosening it, thereby shaking off the dirt that is twisted into the front groove (61) and dialing it into the garbage cavity (67-2). During this process, the auxiliary roller (6577) located on the upper side of the inner groove squeezes and removes water from the continuously rotating cloth cover (64), preventing the sewage from being brought to the subsequent ground, and the rake operation on the auxiliary roller (6577) can rake and comb each rope (653) and scrape off the dirt in the rope (653); S4. When the machine is moved or passed through the carpet without the need for floor cleaning, the operator can detent the buckle (6573) to disengage it from the latch (6574) to unlock the inner shaft (62), then rotate the inner shaft (62) counterclockwise, and rotate the auxiliary roller (6577) out of the inner groove through the bracket (6576), so that the auxiliary roller (6577) replaces roller B (63) and touches the ground, and release the buckle (6573) to lock the inner shaft (62) and the auxiliary roller (6577). At this time, the device can use roller A (4) and the auxiliary roller (6577) to move quickly.
