[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In the present invention, the upper slide drives the trash can to move to the left through the driving rod, and at the same time, the fifth motor operates to clean the inside of the trash can through the driving rod. When the trash can moves to the left and is above the side shovel plate, it stops moving. The fourth motor drives the side shovel plate to move upward, and the side shovel plate drives one side of the trash can to move upward. The trash can flips over ninety degrees with the driving rod as the center point, and at the same time drives the driving rod to rotate ninety degrees. At this time, the upper slide starts to reset and drives the trash can to move to the right. When the trash can moves, the upper and lower sides are cleaned by the second brush. The four surfaces and the inside of the trash can are cleaned by using a cleaning machine and an upper cleaning rack, and it can be automatically turned over for cleaning, thereby playing a role in fully cleaning the trash can. No manual intervention is required, the cleaning is comprehensive, and dead corners are reduced.

[0013] In the present invention, when the trash can is moved inside the cleaning machine and the upper cleaning rack for cleaning, a water tank is arranged inside the cleaning machine, and the water pump inside the water tank transmits water to the water pipe rack through a water pipe, and then sprays water upward through a spray nozzle, and the water mist is sprayed onto the surface of the trash can, and then a second brush is provided to roll the brush, thereby effectively improving the cleaning ability. When the trash can is moved inside the cleaning machine and the upper cleaning rack, the bottom of the trash can contacts with the fixed back plate and can be cleaned by the fixed back plate, thereby realizing comprehensive cleaning of the trash can.

[0014] In the present invention, three inner clamping plates are arranged on the surface of the driving rod, and the sizes of the three inner clamping plates are consistent with the inner wall of the trash can, so the driving rod can drive the trash can to move horizontally through the inner clamping plates. While moving, the rotation of the fifth motor will drive multiple groups of first brushes on the surface to rotate through the driving rod. The rotation of multiple groups of first brushes can clean the inner wall of the trash can. Since the inner clamping plates are rotatably connected to the driving rod, and each inner clamping plate is blocked to the left and right by two fixed rings, the driving rod will not drive the inner clamping plates to rotate. By arranging the driving rod to not only drive the trash can to move, but also clean the inside of the trash can, the power can be effectively utilized and the efficiency of cleaning the trash can is improved.

[0015] In the present invention, the trash can is turned over by the inner clamping plate driving the driving rod to rotate. When the trash can rotates, its own height increases. At this time, the trash can will drive the upper slide to move upward through the driving rod. The upper slide slides upward outside the T-shaped slide. At this time, the upper slide can adapt to the height of the trash can. The trash can is turned over by using the side shovel plate, so that the trash can can be automatically cleaned from multiple sides. At the same time, the upper slide and the lower slide are height-adjustable, so that they can adapt to trash cans of different heights. While improving the cleaning ability, it also improves the applicability to different trash cans. There is no need to change the cleaning equipment, and trash cans of various specifications can be cleaned.

[0016] In the present invention, after the trash can is flipped over and raised, the trash can will apply an upward thrust to the multiple groups of second cleaning rollers inside the upper cleaning frame. The multiple groups of second cleaning rollers move upward, driving the side slide frames on both sides to move upward. The multiple groups of side slide frames all move in the side slide grooves. The multiple groups of side slide frames move upward and drive the second spring to compress and deform. By arranging the second cleaning roller assembly in the upper cleaning frame to be liftable, it can be coordinated with trash cans of different heights to achieve the optimal cleaning distance and improve the cleaning capacity.

[0017] In the present invention, the first cleaning roller and the first brush cover are connected, and then the user puts the second brush cover into the first cleaning roller or the second cleaning roller, and then inserts the L-shaped block on the side wall of the second brush cover into the arc-shaped slide rail, and then rotates the second brush cover. The rotation of the second brush cover drives the L-shaped block to rotate in the arc-shaped slide rail, and the arc-shaped baffle in the arc-shaped slide rail clamps the L-shaped block. At the same time, the two magnetic blocks on the side walls of the first brush cover and the second brush cover are magnetically attracted. At this time, the first brush cover and the second brush cover are installed. By designing the first cleaning roller, the second cleaning roller and the first brush cover and the second brush cover to be detachable, it is convenient for the user to adjust according to different trash cans. At the same time, different second brush covers can be replaced according to different parts of different trash cans, so that the best second brush suitable for cleaning the trash can can be achieved, thereby improving the cleaning ability.

[0034] Working principle:

[0035] In the first step, when the user cleans the trash can 47, the user puts the trash can 47 into the right side of the cleaning machine 1 and the upper cleaning frame 45, and the trash can 47 enters the cleaning machine 1 and the upper cleaning frame 45. The first motor inside the cleaning machine 1 and the third motor inside the upper cleaning frame 45 drive the first cleaning roller 33 and the second cleaning roller 42 to rotate. The rotation of the first cleaning roller 33 and the second cleaning roller 42 will drive the first brush cover 35 and multiple second brush covers 36 on the surface to rotate. The rotation of multiple first brush covers 35 and second brush covers 36 will drive the second brush 37 on the surface to rotate. The cleaning machine 1 and the upper cleaning frame 45 clean the upper and lower surfaces of the trash can 47 through the second brushes 37 on the upper and lower sides. At the same time, the upper slide 26 is driven to move left by the first threaded rod 12, and the upper slide 26 drives the trash can 47 through the driving rod 29 The trash can 47 moves to the left, and at the same time, the fifth motor 28 operates to clean the inside of the trash can 47 through the drive rod 29. When the trash can 47 moves to the left and is above the side shovel plate 21, it stops moving. The fourth motor 19 drives the side shovel plate 21 to move upward, and the side shovel plate 21 drives one side of the trash can 47 to move upward. The trash can 47 flips ninety degrees with the drive rod 29 as the center point, and at the same time drives the drive rod 29 to rotate ninety degrees. At this time, the upper slide 26 starts to reset and drives the trash can 47 to move to the right. When the trash can 47 moves, the upper and lower sides are cleaned by the second brush 37. By using the cleaning machine 1 and the upper cleaning frame 45, the four surfaces and the inside of the trash can 47 are cleaned, and it can be automatically turned over for cleaning, so that the trash can 47 can be fully cleaned without manual intervention, and the cleaning is comprehensive, reducing cleaning dead corners.

[0036] In the second step, when the trash can 47 is moved inside the cleaning machine 1 and the upper cleaning rack 45 for cleaning, a water tank is arranged inside the cleaning machine 1, and the water pump inside the water tank transmits water to the water pipe rack 15 through a water pipe, and then sprays water upward through the spray nozzle 16, and the water mist is sprayed onto the surface of the trash can 47, and then a second brush 37 is provided to roll the brush, which effectively improves the cleaning ability. When the trash can 47 moves inside the cleaning machine 1 and the upper cleaning rack 45, the bottom of the trash can 47 contacts the fixed back plate 13 and can be cleaned by the fixed back plate 13, thereby achieving comprehensive cleaning of the trash can 47;

[0037] When the trash can 47 is placed between the cleaning machine 1 and the upper cleaning rack 45, the end of the trash can 47 is located above the multiple pulley assemblies 17, and the second motor inside the inner slide rail 11 drives the first threaded rod 12 to rotate. The first threaded rod 12 drives the lower frame 23 to move through the thread, and the movement of the lower frame 23 drives the upper slide 26 to move. The movement of the upper slide 26 can drive the driving rod 29 to move. The surface of the driving rod 29 is provided with three inner card plates 3, and the size of the three inner card plates 3 is consistent with the inner wall of the trash can 47. Therefore, the driving rod 29 can drive the trash can 47 to move horizontally through the inner card plates 3. The fifth motor 28 rotates and drives the plurality of first brushes 32 on the surface to rotate through the driving rod 29 while moving. The rotation of the plurality of first brushes 32 can clean the inner wall of the trash can 47. Since the inner card plate 3 is rotatably connected to the driving rod 29 and each inner card plate 3 is blocked by two fixing rings 31, the driving rod 29 will not drive the inner card plate 3 to rotate. By setting the driving rod 29 to not only drive the trash can 47 to move but also clean the inside of the trash can 47, the power can be effectively utilized and the efficiency of cleaning the trash can 47 can be improved.

[0038] When the trash can 47 moves to above the side shovel plate 21, the fourth motor 19 operates to drive the second threaded rod 2 to rotate, and the second threaded rod 2 drives the side shovel plate 21 to move upward through threaded cooperation. When the side shovel plate 21 moves upward, the upper slide 26 stops operating as a whole and cannot move. The side shovel plate 21 drives one side of the trash can 47 to flip upward. The trash can 47 flips over and drives the driving rod 29 to rotate through the inner card plate 3. When the trash can 47 rotates, its own height increases. At this time, the trash can 47 drives the upper slide 26 through the driving rod 29 Move upward, the upper slide 26 slides upward outside the T-shaped slide 24, and at this time, the upper slide 26 can adapt to the height of the trash can 47. By using the side shovel plate 21 to turn over the trash can 47, the trash can 47 can be automatically cleaned on multiple sides. At the same time, the upper slide 26 and the lower slide 23 are height-adjustable, so they can adapt to trash cans 47 of different heights, improving the cleaning ability and the applicability to different trash cans 47. There is no need to change the cleaning equipment, and trash cans 47 of various specifications can be cleaned;

[0039] After the trash can 47 is turned over and raised, the trash can 47 will apply an upward thrust to the multiple groups of second cleaning rollers 42 inside the upper cleaning frame 45. The multiple groups of second cleaning rollers 42 move upward, driving the side slides 43 on both sides to move upward. The multiple groups of side slides 43 all move in the side slide grooves 46. The multiple groups of side slides 43 move upward, driving the second springs 44 to be compressed and deformed. By arranging the second cleaning roller 42 assembly in the upper cleaning frame 45 to be liftable, it can be coordinated with trash cans 47 at different heights to achieve the optimal cleaning distance and improve the cleaning ability.

[0040] In the third step, since different trash cans 47 have different sizes and specifications, the cleaning parts are different, and the requirements for the second brush 37 on the surfaces of the first brush cover 35 and the second brush cover 36 are different. The user can replace the first brush cover 35 and the second brush cover 36 on the outer ring of the first cleaning roller 33 or the second cleaning roller 42. The user first puts the first brush cover 35 into the first cleaning roller 33 or the second cleaning roller 42. When the thread groove 34 on the inner wall of the middle part of the first brush cover 35 contacts the thread groove 34 on the surface of the first cleaning roller 33, the user rotates it to connect the first cleaning roller 33 and the first brush cover 35. Then the user puts the second brush cover 36 into the first cleaning roller 33 or the second cleaning roller 42, and then inserts the L-shaped block 41 on the side wall of the second brush cover 36 into the arc shaped slide rail 38, and then the second brush cover 36 is rotated. The rotation of the second brush cover 36 drives the L-shaped block 41 to rotate in the arc-shaped slide rail 38. The arc-shaped baffle 39 in the arc-shaped slide rail 38 clamps the L-shaped block 41, and at the same time, the two magnetic blocks 4 on the side walls of the first brush cover 35 and the second brush cover 36 are magnetically attracted. At this time, the first brush cover 35 and the second brush cover 36 are installed. By designing the first cleaning roller 33, the second cleaning roller 42 and the first brush cover 35 and the second brush cover 36 to be detachable, it is convenient for the user to adjust according to different garbage cans 47. At the same time, different second brush covers 36 can be replaced according to different parts of different garbage cans 47, so that the best second brush 37 suitable for cleaning the garbage can 47 can be achieved, thereby improving the cleaning ability.
