[0017] Preferably, the number of the semi-annular water spray shells is two, and the two semi-annular water spray shells are symmetrically arranged.

[0018] Preferably, the floor wiping method using the floor wiping cleaning device comprises the following steps:

[0019] S1: When the user uses the device to clean the floor, water is atomized by the semi-ring water spray shell and then sprayed on the floor. At this time, the sweeping brush rotates to sweep away the debris adhering to the bottom surface, so that it is better removed from the floor. Then, the suction machine in the running state cleans the debris swept by the sweeping brush;

[0020] S2: Then start the motor to drive the cylindrical rod clockwise. At this time, the counterweight ball rod on the cylindrical rod deflects and expands under the action of the centrifugal force generated by the rotation of the cylindrical rod, and pushes the sliding bearing to slide downward on the cylindrical rod through the inclined rod. At this time, the U-shaped frame moves downward synchronously to press the outer ring of the bearing to exert a downward force on the transmission belt, causing the transmission belt to deform and drive the brush strip on its lower side to contact the ground. The device can also regulate the force of the brush strip against the ground by the speed of motor rotation;

[0021] When the motor drives the cylindrical rod to rotate clockwise, it drives the driving gear to rotate clockwise. At this time, the driven gear drives the flat gear to rotate counterclockwise under the action of the driven gear, driving the transmission gear shaft to rotate counterclockwise. At this time, the transmission gear shaft drives the ring sleeve to rotate counterclockwise. Since the ring sleeve is eccentrically arranged, when the transmission gear shaft drives the ring sleeve to rotate, the elastic rod located just above the central axis of the transmission gear shaft will be forced to extend out of the ring sleeve. At this time, the elastic rod will drive the row brush on it to synchronously extend out of the ring sleeve to brush the bottom surface of the brush strip in the clockwise transmission state, reducing the amount of stains adhering to the surface of the brush strip, and when the row brush follows the ring sleeve to rotate to just below the central axis of the transmission gear shaft, the row brush will follow the elastic rod to retract into the inside of the ring sleeve. At this time, the stains scraped by the row brush will be discharged from the outside of the ring sleeve, and the row brush continues to process the surface of the brush strip in this way, thereby increasing the working time of the brush strip.

[0022] S3: And because the ring sleeve rotates synchronously with the transmission gear shaft, the stains scraped by the brush will be squeezed into the scraping belt, and the hollow worm on the surface of the ring sleeve drives the worm wheel to rotate during the rotation, prompting the scraping belt to be driven, and the stains on it to be transported into the arc shell. At this time, the C-shaped scraper scrapes and collects the stains on the scraping belt. Since the stains are squeezed into the interior of the collection box, the cavity formed by the collection box and the slide will gradually be filled, prompting the collection box to be passively moved out of the limit shell, thereby achieving the purpose of increasing the volume of the collection cavity. At this time, the seal will passively block the arc groove. The user can observe the remaining volume of the collection box according to the amount of the collection box moved out, so that the user can clean the collection box regularly.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In the present invention, when the device cleans the floor, water is atomized by a semi-annular water spray shell and then sprayed on the floor. At this time, the sweeping brush rotates to sweep away the debris adhering to the bottom surface, so that it is better separated from the floor. Then, the suction machine in the running state cleans the debris swept out by the sweeping brush.

[0025] In the present invention, the motor drives the cylindrical rod to rotate clockwise. At this time, the counterweight ball rod on the cylindrical rod is deflected and expanded under the action of the centrifugal force generated by the rotation of the cylindrical rod. The sliding bearing is pushed downward on the cylindrical rod by the inclined rod. At this time, the U-shaped frame moves downward synchronously to press the outer ring of the bearing to apply a downward force to the transmission belt, causing the transmission belt to deform and drive the brush strip on its lower side to contact the ground. The device can also regulate the force of the brush strip against the ground by the speed of motor rotation.

[0026] In the present invention, when the cylindrical rod is driven by the motor to rotate clockwise, since the ring sleeve is eccentrically arranged, when the transmission gear shaft drives the ring sleeve to rotate, the elastic rod located just above the central axis of the transmission gear shaft will be forced to extend from the ring sleeve. At this time, the elastic rod will drive the row brush thereon to synchronously extend from the ring sleeve to brush the bottom surface of the brush strip in the clockwise transmission state, thereby reducing the amount of stains adhering to the surface of the brush strip, and when the row brush follows the ring sleeve to rotate to just below the central axis of the transmission gear shaft, the row brush will follow the elastic rod to retract into the inside of the ring sleeve. At this time, the stains scraped by the row brush will be discharged to the outside of the ring sleeve, and the row brush will continue to treat the surface of the brush strip in this way, thereby increasing the working time of the brush strip.

[0027] In the present invention, since the ring sleeve rotates synchronously with the transmission gear shaft, the stains scraped by the brush will be squeezed into the scraping belt, and the hollow worm on the surface of the ring sleeve drives the worm wheel to rotate during the rotation, prompting the scraping belt to be transmitted, and driving the stains on it to be transported into the arc shell. At this time, the C-shaped scraper scrapes and collects the stains on the scraping belt. Since the stains are squeezed into the interior of the collection box, the cavity formed by the collection box and the slide will gradually be filled, prompting the collection box to be passively moved out of the limit shell, thereby achieving the purpose of increasing the volume of the collection cavity, and at this time the seal will passively block the arc groove, and the user can observe the remaining volume of the collection box according to the amount of the collection box moved out, so that the user can clean the collection box regularly.

[0051] In this embodiment, Figure 1 and Figure 2 As shown, there are two semi-annular water spray shells 3, and the two semi-annular water spray shells 3 are symmetrically arranged.

[0052] The mopping method and advantages of the present invention: The mopping method of the cleaning device for mopping the floor has the following working process:

[0053] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown:

[0054] S1: When the user uses the device to clean the floor, the semi-annular water spray shell 3 atomizes water and then sprays it on the floor. At this time, the sweeping brush 2 rotates to sweep away the debris adhering to the bottom surface, so that it is better removed from the floor. Then, the suction machine 5 in operation cleans the debris swept by the sweeping brush 2.

[0055] S2: Then start the motor 62 to drive the cylindrical rod 61 clockwise. At this time, the counterweight ball rod 63 on the cylindrical rod 61 is deflected and expanded under the action of the centrifugal force generated by the rotation of the cylindrical rod 61, and the sliding bearing 65 is pushed downward on the cylindrical rod 61 through the inclined rod 64. At this time, the U-shaped frame 67 moves downward synchronously to press the outer ring of the bearing 68 to apply a downward force to the transmission belt 612, causing the transmission belt 612 to deform and drive the brush strip 615 on its lower side to contact the ground. The device can also regulate the force of the brush strip 615 against the ground by the rotation speed of the motor 62.

[0056] When the motor 62 drives the cylindrical rod 61 to rotate clockwise, it drives the driving gear 71 to rotate clockwise. At this time, the flat gear 73 is driven to rotate counterclockwise under the action of the driven gear 72, and the transmission gear shaft 74 is driven to rotate counterclockwise. At this time, the transmission gear shaft 74 drives the ring sleeve 76 to rotate counterclockwise. Since the ring sleeve 76 is eccentrically arranged, when the transmission gear shaft 74 drives the ring sleeve 76 to rotate, the elastic rod 77 located on the upper side of the central axis of the transmission gear shaft 74 will be forced to extend from the ring sleeve 76. At this time, the elastic rod 77 will drive the ring sleeve 76 on it. The row brush 78 is synchronously extended from the ring sleeve 76 to brush the bottom surface of the brush strip 615 in the clockwise transmission state, reducing the amount of dirt adhering to the surface of the brush strip 615. When the row brush 78 rotates with the ring sleeve 76 to the lower side of the central axis of the transmission gear shaft 74, the row brush 78 will follow the elastic rod 77 to retract into the inside of the ring sleeve 76. At this time, the dirt scraped by the row brush 78 will be discharged to the outside of the ring sleeve 76. The row brush 78 continues to treat the surface of the brush strip 615 in this way, thereby increasing the working time of the brush strip 615.

[0057] S3: And because the ring sleeve 76 rotates synchronously with the transmission gear shaft 74, the stains scraped off by the brush 78 will be squeezed into the scraping belt 83, and the hollow worm 81 on the surface of the ring sleeve 76 drives the worm wheel 82 to rotate during the rotation, prompting the scraping belt 83 to be transmitted, and driving the stains on it to be transported into the arc shell 85. At this time, the C-shaped scraper 88 scrapes and collects the stains on the scraping belt 83. Since the stains are squeezed into the interior of the collection box 86, the cavity formed by the collection box 86 and the slide plate 87 will gradually be filled, prompting the collection box 86 to be passively moved out of the limit shell 616, thereby achieving the purpose of increasing the volume of the collection cavity, and at this time the seal 810 will passively block the arc groove 89. The user can observe the remaining volume of the collection box 86 according to the amount of the collection box 86 moved out, so that the user can clean the collection box 86 regularly.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.

5. The floor-wiping cleaning device according to claim 1, characterized in that: The number of the semi-annular water spray shells (3) is two, and the two semi-annular water spray shells (3) are symmetrically arranged.

6. A floor wiping method using a floor wiping cleaning device according to claim 4, characterized in that: The steps include: S1: When the user uses the device to clean the floor, the semi-circular water spray shell (3) atomizes water and then sprays it on the floor. At this time, the sweeping brush (2) rotates to sweep away the debris adhering to the bottom surface, so that the debris is better separated from the floor. Then, the suction machine (5) in operation cleans the debris swept out by the sweeping brush (2); S2: Then the motor (62) is started to drive the cylindrical rod (61) clockwise. At this time, the counterweight ball rod (63) on the cylindrical rod (61) is deflected and expanded under the action of the centrifugal force generated when the cylindrical rod (61) rotates, and the sliding bearing (65) is pushed downward on the cylindrical rod (61) through the inclined rod (64). At this time, the U-shaped frame (67) is synchronously moved downward to press the outer ring of the bearing (68) to apply a downward pressure to the transmission belt (612), causing the transmission belt (612) to deform and drive the brush strip (615) on its lower side to contact the ground. The device can regulate the force of the brush strip (615) against the ground by the speed of rotation of the motor (62); When the motor (62) drives the cylindrical rod (61) to rotate clockwise, the driving gear (71) is driven to rotate clockwise. At this time, the flat gear (73) is driven to rotate counterclockwise under the action of the driven gear (72), and the transmission gear shaft (74) is driven to rotate counterclockwise. At this time, the transmission gear shaft (74) drives the ring sleeve (76) to rotate counterclockwise. Since the ring sleeve (76) is eccentrically arranged, when the transmission gear shaft (74) drives the ring sleeve (76) to rotate, the elastic rod (77) located on the upper side of the central axis of the transmission gear shaft (74) will be forced to extend from the ring sleeve (76). At this time, the elastic rod (77) will drive the ring sleeve (76) on it. The row brush (78) is synchronously extended from the ring sleeve (76) to brush the bottom surface of the brush strip (615) in the clockwise transmission state, reducing the amount of stains adhering to the surface of the brush strip (615), and when the row brush (78) rotates with the ring sleeve (76) to the lower side of the central axis of the transmission gear shaft (74), the row brush (78) will follow the elastic rod (77) to shrink into the inside of the ring sleeve (76), and the stains scraped by the row brush (78) will be discharged to the outside of the ring sleeve (76). The row brush (78) continues to process the surface of the brush strip (615) in this way, increasing the working time of the brush strip (615); S3: Since the ring sleeve (76) rotates synchronously with the transmission gear shaft (74), the dirt scraped by the brush (78) will be squeezed into the scraping belt (83), and the hollow worm (81) on the surface of the ring sleeve (76) drives the worm wheel (82) to rotate during the rotation process, prompting the scraping belt (83) to drive and transport the dirt on it into the arc shell (85). At this time, the C-shaped scraper (88) scrapes and collects the dirt on the scraping belt (83). Since the dirt is squeezed, The liquid flows into the interior of the collection box (86), and the cavity formed by the collection box (86) and the slide (87) is gradually filled, prompting the collection box (86) to passively move out of the limit shell (616), thereby increasing the volume of the collection cavity. At this time, the seal (810) will passively block the arc groove (89). The user can observe the remaining volume of the collection box (86) according to the amount of the collection box (86) moved out, so that the user can clean the collection box (86) regularly.
