[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The lower right end of the sewage tank 1 is connected to the upper left end of the clean water tank 2 through a connecting pipe 3, and the connecting pipe 3 is set higher on the left and lower on the right. When the water line inside the clean water tank 2 is lower than the right end of the connecting pipe 3, the water inside the sewage tank 1 can smoothly pass through the connecting pipe 3 into the inside of the clean water tank 2. A driving adjustment mechanism 4 is set on the right side of the sewage tank 1. The driving adjustment mechanism 4 includes an electric telescopic rod 401. The electric telescopic rod 401 is set on the right outer wall of the sewage tank 1 through a mounting seat. The electric telescopic rod 401 A servo motor 402 is provided at the front end, a moving groove 39 is provided on the right outer wall of the sewage tank 1, and a motor seat 403 is movably installed inside the moving groove 39, the servo motor 402 is arranged on the upper surface of the motor seat 403, and a rotating gear 404 is provided on the circumferential surface of the power output end of the servo motor 402, the front end of the rotating gear 404 is meshedly connected with a driven gear 1 405, and the rear end of the rotating gear 404 is meshedly connected with a driven gear 2 406, and a rotating rod 1 407 is provided on the left side of the driven gear 2 406, and the rotating rod 1 407 is rotatably installed on the right side wall of the sewage tank 1;

[0031] It should be noted that the initial position of the rotating gear 404 is meshed with the driven gear 1 405, that is, when the servo motor 402 drives the rotating gear 404 to rotate, the rotating gear 404 will only drive the driven gear 1 405 to rotate, and when the electric telescopic rod 401 drives the servo motor 402 to move backward, the rotating gear 404 will only mesh with the driven gear 2 406, that is, when the servo motor 402 drives the rotating gear 404 to rotate, the rotating gear 404 will only drive the driven gear 2 406 to rotate.

[0032] A transmission mechanism 5 is arranged above the rotating rod 1 407, and the transmission mechanism 5 includes a belt driving wheel 501, a transmission belt 502 and a belt driven wheel 503, and the belt driving wheel 501 is connected to the belt driven wheel 503 through the transmission belt 502, and the belt driving wheel 501 is arranged on the circumferential surface on the left side of the rotating rod 1 407;

[0033] A worm 6 is provided on the upper surface of the sewage tank 1, and a belt driven wheel 503 is provided on the circumferential surface of the right end of the worm 6. When the driven gear 2 406 drives the rotating rod 1 407 to rotate, the rotating rod 1 407 can drive the worm 6 to rotate through the transmission mechanism 5. The front end of the worm 6 is meshedly connected with a worm wheel 7, and a rotating shaft 8 is provided at the lower end of the worm wheel 7. A turntable 9 is provided at the lower end of the rotating shaft 8. The rotating shaft 8 and the turntable 9 are both rotatably installed inside the upper end of the sewage tank 1. Lifting blocks 10 are provided inside the left and right ends of the turntable 9. The circumferential surfaces of the lower ends of the two lifting blocks 10 are threadedly connected with threaded socket blocks 13. The circumferential surface of the upper end of the lifting block 10 is provided with a spring 11. The lower end of the spring 11 is connected to the turntable 9, and the upper end of the spring 11 is connected to the upper protruding end of the lifting block 10. The inner bottom of the turntable 9 A switch 12 is provided at the bottom, and the switch 12 is provided below the protruding end of the upper part of the lifting block 10. The setting of the spring 11 can push the lifting block 10 upward, so that the initial position of the lifting block 10 abuts against the inner top wall of the turntable 9. Then, when the lifting block 10 is subsequently subjected to an elastic force greater than the spring 11, the lifting block 10 will move downward, press the switch 12, and perform other work. The circumferential surface of the lower end of the lifting block 10 is provided with an external thread matching the threaded sleeve block 13, and the lower end of the threaded sleeve block 13 is provided with a filter cartridge 14. The setting of the lifting block 10 and the threaded sleeve block 13 enables the filter cartridge 14 to be quickly installed on the lifting block 10 through the threaded sleeve block 13, or removed from the lifting block 10, thereby improving the installation and removal efficiency of the filter cartridge 14, and making it more convenient and quick to use.

[0034] It should be noted that, because there is a self-locking effect between the worm wheel 7 and the worm 6, when the turntable 9 is subjected to vibration during operation of the device, the turntable 9 will not drive the worm 6 to rotate in the opposite direction through the worm wheel 7, so that the filter cartridge 14 can be stably located below the turntable 9, thereby preventing the filter cartridge 14 from being shifted in position and causing the sewage to directly enter the interior of the sewage tank 1 without passing through the filter cartridge 14.

[0035] The circumferential outer surface of the upper end of the filter cartridge 14 is provided with a clamping block 15 and a clamping block 2 16, and four clamping blocks 15 and two clamping blocks 16 are provided, and the clamping block 15 is arranged above the clamping block 2 16. The circumferential outer surface of the filter cartridge 14 is sleeved with a metal outer cylinder 17, and the filter cartridge 14 is clamped with the metal outer cylinder 17 through the clamping block 15 and the clamping block 2 16. The upper end of the metal outer cylinder 17 is respectively provided with a clamping groove 22, a lifting groove 24 and an annular groove 23 from the inside to the outside, and the clamping groove 22 and the annular groove 23 are provided with four. The four clamping blocks 15 are respectively clamped on An annular connecting plate 18 is provided inside the four card slots 22 and the annular slot 23, a lifting rod 19 is provided inside the lifting slot 24, and a stopper 21 is provided on the circumferential surface of the lower end of the lifting rod 19. The four lifting rods 19 are connected to the inner ring of the annular connecting plate 18, and the circumferential surface of the four lifting rods 19 is sleeved with a spring 20, the lower end of the spring 20 abuts against the stopper 21, and the upper end of the spring 20 abuts against the inside of the metal outer tube 17, and the lower ends of the four lifting rods 19 are respectively inserted into the upper ends of the four card blocks 16;

[0036] It should be noted that after the filter cartridge 14 is installed inside the metal outer cylinder 17, the distance between the upper surface of the block 2 16 and the inner top wall of the metal outer cylinder 17 is greater than the length of the block 15 plus the lifting rod 19 inserted into the block 2 16. Then, when disassembly is required, the filter cartridge 14 is first moved upward, driving the block 15, the upper part of the lifting rod 19 and the annular connecting plate 18 to move out of the metal outer cylinder 17, so that the block 2 16 is in contact with the inner top wall of the metal outer cylinder 17, and then the lifting rod 19 is moved upward again to move the bottom of the lifting rod 19 out from the upper end of the block 2 16. At this time, the filter cartridge 14 can be rotated horizontally forty-five degrees so that the block 2 16 is vertically corresponding to the slot 22. Then, the filter cartridge 14 can be taken out from the metal outer cylinder 17 as a whole, which is convenient for cleaning and replacement of the filter cartridge 14.

[0037] An arc-shaped water inlet groove 36 is provided on the upper surface of the filter cartridge 14, and a movable plug-in pipe 31 is inserted into the interior of the right arc-shaped water inlet groove 36. The upper end of the movable plug-in pipe 31 passes through the upper end of the sewage tank 1 and is connected to the sewage inlet pipe 29 through the corrugated pipe 30. A circular bottom plate 25 is provided on the lower surface of the metal outer cylinder 17. A plurality of circular vertical rods 26 are provided in a circumferential array on the lower surface of the circular bottom plate 25. A rotating rod 27 is provided below the circular vertical rod 26. A driven gear 1 405 is provided on the circumferential surface of the right end of the rotating rod 27. An intermittent gear 28 is provided on the circumferential surface of the right side of the rotating rod 27. There are two intermittent gears 28, which are respectively provided at the left and right ends below the right circular bottom plate 25. The movable plug-in pipe 3 1 is provided with an annular stopper 32 on the circumferential outer surface of the middle part, and the annular stopper 32 is provided inside the upper end of the sewage tank 1, and a spring 33 is provided on the upper surface of the annular stopper 32, and the upper end of the spring 33 abuts against the upper end of the sewage tank 1, and an annular abutment block 34 is provided on the circumferential outer surface of the lower end of the movable plug-in tube 31, and the lower surface of the annular abutment block 34 abuts against the upper surface of the filter cartridge 14 through the ball 35, and the annular corner at the lower end of the movable plug-in tube 31 is designed in an arc shape. The arc-shaped design of the bottom of the movable plug-in tube 31 enables the filter cartridge 14 to push the movable plug-in tube 31 out of the arc-shaped water inlet groove 36 when the turntable 9 drives the filter cartridge 14 to rotate horizontally, so as to avoid the movable plug-in tube 31 affecting the switching work of the two filter cartridges 14;

[0038] It should be noted that when the empty filter cartridge 14 is located below the movable plug-in tube 31, the arc-shaped portion of the lower end of the movable plug-in tube 31 will be inserted into the arc-shaped water inlet groove 36 of the filter cartridge 14, and at the same time, it will be movably abutted against the upper surface of the filter cartridge 14 through the annular abutment block 34 and the ball 35, so that when the filter cartridge 14 rotates, it will not affect the movable plug-in tube 31, and the initial position of the annular limit block 32 on the movable plug-in tube 31 is not in contact with the inner bottom of the sewage tank 1, and some space is left. When the filter cartridge 14 moves downward after collecting more impurities, the movable plug-in tube 31 can follow the descent to avoid the lower end of the movable plug-in tube 31 from being separated from the filter cartridge 14, resulting in sewage being unable to enter the filter cartridge 14.

[0039] The left wall of the sewage tank 1 is hinged with a sealing door 37 through a hinge shaft. The sealing door 37 is located on the left side of the metal outer cylinder 17. Because the connecting pipe 3 is connected to the top of the clean water tank 2, as long as the water inside the clean water tank 2 is not higher than the connecting pipe 3, and when the floor cleaning machine is in use, water resources are always consumed, so the water line inside the clean water tank 2 is always falling, and then when the water line inside the clean water tank 2 is lower than the connecting pipe 3, the treated water inside the sewage tank 1 will flow into the inside of the clean water tank 2 through the connecting pipe 3, and the bottom of the sewage tank 1 will not accumulate too much The water in the sewage tank 1 will not be higher than the bottom of the sealing door 37, and when the sealing door 37 is opened later, the water in the sewage tank 1 will not flow out from the sealing door 37. A fixing block 38 is provided on the upper surface of the sewage tank 1, and the worm 6 is rotatably installed inside the fixing block 38. The setting of the fixing block 38 can limit the worm 6 without affecting the rotation of the worm 6. A water inlet pipe is provided on the right side of the upper end of the clean water tank 2. The setting of the water inlet pipe can inject clean water into the clean water tank 2 through the water inlet pipe before using the floor cleaning machine.

[0040] When the present invention is in use, when the floor cleaning machine is used to clean the floor, sewage will enter the interior of the right filter cartridge 14 inside the sewage tank 1 through the sewage inlet pipe 29, and the servo motor 402 is started at this time. Because the rotating gear 404 is meshed with the driven gear 1 405 at this time, but not with the driven gear 2 406, when the servo motor 402 works to drive the rotating gear 404 to rotate, the rotating gear 404 will only drive the driven gear 1 405 to rotate, and the driven gear 1 405 rotates to drive the rotating rod 2 27 and the two intermittent gears 28 to rotate, and the intermittent gear 28 When rotating, the intermittent gear 28 on the right side will first contact the circular vertical rod 26, thereby driving the right metal outer cylinder 17 to rotate counterclockwise for a short distance, and then the intermittent gear 28 on the right side will no longer contact the circular vertical rod 26, and the intermittent gear 28 on the left side will contact the circular vertical rod 26, driving the right metal outer cylinder 17 to rotate clockwise back to the initial position, so that under the continuous rotation of the rotating rod 27, the right metal outer cylinder 17 will reciprocate, so that it can shake the sewage inside the filter cartridge 14, reducing the probability of impurities blocking the filter holes and improving the filtering effect and filtering quality;

[0041] After working for a period of time, due to excessive accumulation of impurities inside the right filter cartridge 14, some filter holes will be blocked by the accumulated impurities, making the sewage filtering efficiency worse. At this time, sewage will accumulate inside the right filter cartridge 14, causing the filter cartridge 14 to become heavier. When the overall weight of the filter cartridge 14 and the metal outer cylinder 17 exceeds the limit of the elastic force of the spring 11, the spring 11 can no longer support the lifting block 10 upward. The lifting block 10 will move downward due to the gravity of the metal outer cylinder 17 and the filter cartridge 14. When the lifting block 10 contacts and presses down the switch 12 below it, the switch 12 sends a signal, closing the sewage inlet pipe 29 and stopping the servo motor 402.

[0042] Then, the electric telescopic rod 401 is started, and the electric telescopic rod 401 drives the servo motor 402 and the motor seat 403 to move backward horizontally, so that the rotating gear 404 is no longer meshed with the driven gear 1 405, and is meshed with the driven gear 2 406. At this time, the servo motor 402 is started again, and the servo motor 402 drives the rotating gear 404 to rotate, and the rotating gear 404 drives the driven gear 2 406 to rotate, and the driven gear 2 406 drives the rotating rod 1 407 to rotate, and the rotating rod 1 407 drives the worm 6 to rotate through the transmission mechanism 5, and the rotation of the worm 6 drives the worm wheel 7, the rotating shaft 8 and the rotating disk 9 to rotate, so that the rotating disk 9 drives the two metal outer cylinders 17 below it to rotate 180 degrees, so that the two The position of the metal outer cylinder 17 is replaced, so that the empty filter cartridge 14 is moved to the bottom of the sewage inlet pipe 29, and when the metal outer cylinder 17 rotates, because the lower end of the movable plug-in tube 31 is designed in an arc shape and the ball 35 at the bottom of the annular abutment block 34 is set, when the filter cartridge 14 moves horizontally, the movable plug-in tube 31 can be smoothly pushed upward to the upper end of the filter cartridge 14, so as to avoid the movable plug-in tube 31 affecting the filter cartridge 14 when the filter cartridge 14 rotates. Then, after the positions of the two metal outer cylinders 17 are replaced, the electric telescopic rod 401 drives the servo motor 402 to move forward and reset, so that the servo motor 402 drives the filter cartridge 14 and the metal outer cylinder 17 on the right side to reciprocate when working again;

[0043] After the floor is cleaned, or when both filter cartridges 14 are full of impurities, the sealing door 37 is opened, and the metal outer cylinder 17 on the left is rotated so that the threaded sleeve block 13 is unscrewed from the lifting block 10, and then the metal outer cylinder 17 can be taken out from the interior of the sewage tank 1, and then the filter cartridge 14 is pulled up, so that the filter cartridge 14 pushes the lifting rod 19 and the annular connecting plate 18 upward through the clamping block 2 16, so that the upper part of the lifting rod 19 and the annular connecting plate 18 are moved as a whole to the top of the metal outer cylinder 17, and the annular connecting plate 18 is fixed. At this time, the clamping block 15 has been moved out from the inside of the clamping groove 22 and is located above the metal outer cylinder 17, and the clamping block 2 16 is in contact with the inner top wall of the metal outer cylinder 17. Then, after the filter cartridge 14 is rotated horizontally by forty-five degrees, the clamping block 2 16 corresponds vertically to the clamping groove 22, and then the filter cartridge 14 is moved vertically upward, and it can be taken out from the inside of the metal outer cylinder 17 as a whole, which is convenient for subsequent cleaning and replacement.
