Description

Technical Field

[0001] This utility model relates to the field of swimming pool maintenance equipment, and in particular to a swimming pool cleaning robot. Background Technology

[0002] For many families, having a pool of clear water is a great enjoyment in summer. Pool cleaning robots can effectively reduce the cleaning burden of home pools, automatically handle floating objects on the surface and sediment at the bottom, keeping the pool clean. This not only helps family members enjoy water activities with more peace of mind, but also improves the overall aesthetics and hygiene of the home pool.

[0003] When pool cleaning robots are working, especially when dealing with large pieces of debris in the pool (such as grass clippings, leaves, plastic bags, etc.), this debris is easily sucked into the machine, particularly into the collection bin. Because of its large size, this debris can easily accumulate and clog the collection bin. Once clogged, it not only affects the robot's efficiency but can also cause it to malfunction and stop, requiring manual cleaning and repair. This undoubtedly increases both operating and time costs.

[0004] Secondly, after the pool cleaning robot completes its cleaning work, the operator needs to remove the collection box and empty the trash inside. However, in actual operation, it is often found that some trash, especially small or irregularly shaped trash, sticks to the inside of the collection box and is difficult to remove completely. If this residual trash is not cleaned in time, it will not only affect the effectiveness of the next cleaning work, but may also cause bacteria, mold and other harmful substances to grow inside the collection box, thus adversely affecting the hygiene quality of the pool.

[0005] Therefore, it is necessary to provide a new pool cleaning robot to solve the above-mentioned technical problems. Utility Model Content

A water pump 6 is located on one side of the filter belt 3, with its suction port located at the top of the filter belt 3. A collection tank 7 is located on the other side of the filter belt 3, with drain outlets evenly spaced on its outer wall. A cleaning brush 71 is installed inside the collection tank 7, and a cleaning assembly is installed between the collection tank 7 and the cleaning brush 71. The cleaning brush 71 moves up and down to clean the dirt inside the collection box 7. The transmission mechanism includes a drive pulley 8, a driven pulley 9, and a worm gear 10. The drive pulley 8 is fixedly connected to the rotating shaft at the other end of the cleaning machine 1. The worm gear 10 is rotatably connected inside the cleaning machine 1 near the drive pulley 8. One end of the worm gear 10 is fixedly connected to the driven pulley 9. The drive pulley 8 and the driven pulley 9 are connected by a belt drive. Rotating rods 11 are rotatably connected inside both ends of the filter belt 3. One of the two rotating rods 11 is fixedly connected to a worm gear 12 near the driven pulley 9. The worm gear 12 meshes with the worm gear 10. Guide plates 13 are rotatably connected to both ends of the two rotating rods 11. Guide grooves 14 are opened on the side of the two guide plates 13 near the filter belt 3. The two sides of the filter belt 3 are slidably connected to the inner wall of the corresponding guide groove 14.

[0032] It should be noted that a waterproof battery and a waterproof motor are installed near the rear wheel of the cleaning machine 1. The waterproof battery provides power to the entire device. The key electronic components and circuit boards inside the cleaning machine 1 have undergone strict waterproofing treatment to achieve a high waterproof rating, ensuring that they will not be damaged by water immersion during underwater operations.

[0033] The sludge collection box 4 is made of plastic and has a certain degree of elasticity. It has arc-shaped slots on both sides and engages with one of the two rotating rods 11 that is away from the worm gear 10. When the operator removes it, he only needs to pull the sludge collection box 4 so that the arc-shaped slots on both sides disengage from the rotating rod 11. The rotating rod 11 on one side of the sludge collection box 4 is installed in cooperation with the sludge collection box 4 through a torsion spring. When the filter belt 3 brings large pieces of garbage into the sludge collection box 4, it compresses the torsion spring. When the garbage passes through, the rotating cover 5 automatically resets to prevent large pieces of garbage from overflowing.

[0034] Please see Figure 3 and Figure 7 The cleaning components include: a U-shaped slide bar 15, a connecting rod 17, and a cylinder 18. The cylinders 18 are fixedly connected to both sides of the collection box 7. The U-shaped slide bar 15 is slidably connected to the inner wall of the two cylinders 18. The connecting rods 17 are symmetrically fixedly connected to the top of the U-shaped slide bar 15. The bottom ends of the two connecting rods 17 extend into the collection box 7 and are fixedly connected to the cleaning brush 71. The filter screen 20 is fixedly connected to the inner wall of the collection box 7. The outer wall of the cleaning brush 71 is provided with soft bristles, which are tightly fitted with the filter screen 20. The top of the cleaning machine 1 is rotatably connected to the collection cover 21. The outlet of the water pump 6 is connected to one side of the collection cover 21. The top of the collection box 7 is fixedly connected to the handle 22. The handle 22 has symmetrical holes inside that allow the two connecting rods 17 to pass through.

[0035] It should be noted that the handle 22 has a hole inside that allows the connecting rod 17 to pass through, so that when the operator pulls the U-shaped slide rod 15 to clean the filter screen 20 inside the collection box 7, the connecting rod 17 is not obstructed. One side of the collection cover 21 is rotatably connected to the top of the cleaning machine 1, and the other side of the collection cover 21 is magnetically attached to the top of the collection box 7. When it is necessary to open the collection cover 21, the operator only needs to apply a little force to open the collection cover 21.

[0036] The working principle of the swimming pool cleaning robot 1 provided by this utility model is as follows:

[0037] I. Initial Startup

[0038] When the cleaning machine 1 starts working, the internal power system of the cleaning machine 1 is activated first, and this power system provides power for the entire cleaning process;

[0039] The power system drives the roller brush 2 to start rotating. The roller brush 2 fits tightly against the bottom of the pool. The friction generated by the rotation sweeps up the dirt, algae, small particles and other debris attached to it. At the same time, the water pump 6 starts working. The water pump 6 is located at the top of the filter belt 3. It draws in water from the pool along with small particles of debris by generating negative pressure. This water and debris then undergo preliminary filtration through the filter belt 3. The filter belt 3 has an arc-shaped design and filter holes on its surface, which can intercept large pieces of debris.

[0040] II. Operation of the transmission mechanism and rotation of filter belt 3

[0041] The rotating shaft at the rear of the cleaning machine 1 begins to rotate; this rotating shaft is directly driven by the power system.

[0042] The driving pulley 8 on the rotating shaft drives the driven pulley 9 to rotate via a belt. The driven pulley 9 is fixedly connected to one end of the worm 10, so the worm 10 also starts to rotate. The worm 10 meshes with the worm wheel 12 on the rotating rod 11 of the filter belt 3 near the driven pulley 9. When the worm 10 rotates, it drives the worm wheel 12 to rotate, which in turn drives the filter belt 3 to start rotating along the rotating rod 11 at both ends. In order to ensure that the filter belt 3 can rotate smoothly and continuously, both sides of the filter belt 3 are slidably connected in the guide grooves 14 in the guide plate 13. These guide grooves 14 provide the necessary support and guidance for the filter belt 3.

[0043] III. Large-item waste collection and small-item waste filtration

[0044] When the filter belt 3 rotates to the vicinity of the sludge collection box 4, the large pieces of garbage attached to it will be intercepted at the entrance of the sludge collection box 4. Because of their large size, these large pieces of garbage cannot pass through the filter holes of the filter belt 3. As the filter belt 3 continues to rotate, these large pieces of garbage will be pushed into the sludge collection box 4. The rotating cover 5 on one side of the sludge collection box 4 is installed in cooperation with the sludge collection box 4 through a torsion spring. The automatic closing action of the rotating cover 5 prevents garbage from overflowing.

[0045] Fine particles of debris continue to pass through the filter belt 3 under the suction of the water pump 6 and enter the collection box 7. Inside the collection box 7, there is a filter screen 20. These fine particles of debris are intercepted by the filter screen 20, while the cleaned water passes through the filter screen 20 and is discharged through the drain on the collection box 7, returning to the pool.

[0046] IV. Cleaning Components Operation

[0047] After the cleaning machine 1 finishes cleaning, the operator first takes out the sludge collection box 4 and cleans out the large pieces of garbage collected inside. Then the operator opens the collection cover 21 on the top of the cleaning machine 1, then holds the handle 22 on the collection box 7 and lifts it up to take out the collection box 7. Then most of the garbage inside the collection box is poured out.

[0048] At this time, the operator holds the top handle 22 of the collection box 7 with one hand and pulls the U-shaped slide bar 15 back and forth with the other hand. The U-shaped slide bar 15 slides inside the cylinder 18, which is fixed on both sides of the collection box 7. The U-shaped slide bar 15 drives the cleaning brush 71 to move up and down inside the collection box 7 through the connecting rod 17. The outer wall of the cleaning brush 71 is provided with soft bristles. These bristles are in close contact with the filter screen 20 and can effectively remove the residual garbage on the filter screen 20. After repeatedly pulling the U-shaped slide bar 15, the garbage stuck to the filter screen 20 inside the collection box 7 is brushed off by the cleaning brush 71. Then the operator rinses it with clean water and reinstalls it inside the cleaning machine 1.
