Technical Field
[0001] This utility model relates to the technical field of water surface cleaning, and in particular to an automatic water surface cleaning machine that prevents garbage from overflowing. Background Technology
[0002] Debris easily floats on water surfaces, such as in swimming pools, rivers, lakes, and reservoirs. In existing technologies, when using a water surface cleaning machine to collect this debris, the machine is first placed in the water. Because the floating device generates buoyancy, the filter screen and filter cylinder of the filtration system float on the water. The pump is then activated, drawing water into the filter screen. The water then passes through the mesh of the filter screen and flows out of the filter cylinder, creating a continuous cycle. As the water flows into the filter screen, it carries debris from the surface into the screen, where it accumulates.
[0003] There is a flaw in real-world automatic water surface cleaning machines: when the pump of the automatic water surface cleaning machine is not pumping water, the debris that has entered the filter screen of the automatic water surface cleaning machine will overflow from the filter screen and return to the water surface. Utility Model Content
[0004] To address the problem mentioned above where, when the pump of the automatic water surface cleaner stops pumping water, the debris that enters the filter screen of the automatic water surface cleaner overflows from the filter screen and returns to the water surface, this utility model provides an automatic water surface cleaner that prevents debris from overflowing.
[0005] This utility model provides an automatic water surface cleaning machine to prevent garbage overflow, and adopts the following technical solution:
[0006] An automatic water surface cleaning machine to prevent garbage overflow includes a filtration device and a water pumping device. The filtration device includes a filter cylinder with a filter screen installed on it. The bottom of the filter cylinder has an opening. It also includes a lifting sleeve, where A ≤ B, A is the average density of the lifting sleeve, and B is the density of water. When the automatic water surface cleaning machine is placed in water, the lifting sleeve can be fitted onto the filtration device and raised or lowered.
[0007] By adopting the above technical solution, when the pump is not started, since A≤B, the lifting sleeve floats in the water, and the top of the lifting sleeve is above or level with the water surface, thereby preventing the garbage in the filter screen from overflowing from the opening of the filter device.
[0008] The water pumping device is located at the bottom of the filter device. The water pumping device includes a water pumping shell and a water pump. The water pumping shell and the filter cylinder form a water pumping chamber, and the opening is connected to the water pumping chamber.
[0009] Optional, A ≥ 80% B.
[0010] By adopting the above technical solution, since the downward pressure exerted on the lifting sleeve by the flowing water is limited, if the average density of the lifting sleeve is too small, after the water pump is started, the power of the water pump is limited, and the flowing water cannot push the top of the lifting sleeve below the water surface. A≥80%B, so that the average density of the lifting sleeve is within this range, even if the power of the water pump is limited, the flowing water can push the top of the lifting sleeve below the water surface. The top does not block the garbage from entering the filter screen, which is conducive to the garbage entering the filter screen smoothly.
[0011] Optionally, the filter screen is fitted onto the filter cylinder, the longitudinal section of the lifting sleeve is U-shaped, and the upper edge of the lifting sleeve has an inner groove, so that the lifting sleeve can be fitted onto the filter screen and raised and lowered.
[0012] By adopting the above technical solution, the lifting sleeve will not be subject to the frictional force of the upper edge of the filter screen, allowing the lifting sleeve to float under the buoyancy of the water and descend under the downward pressure of the water.
[0013] Optionally, D≤C≤1.2D, where C is the width of the inner groove and D is the width of the upper edge of the filter screen.
[0014] By adopting the above technical solution, it is possible to prevent the lifting sleeve from shaking significantly on the upper edge of the filter screen.
[0015] Optionally, a flotation device is connected to the outer wall of the filter cartridge, and the average density of the flotation device is less than that of water.
[0016] By adopting the above technical solution, the cleaning machine can float on water.
[0017] Optionally, the number of floating devices is three, and the three floating devices are evenly installed on the outer wall of the filter cylinder.
[0018] By adopting the above technical solution, the weight of the cleaning machine is more balanced on both sides, reducing yaw caused by gravity imbalance and enhancing the stability of the cleaning machine during operation.
[0019] Optionally, the upper edge of the filter screen is fitted over the upper edge of the filter cartridge.
[0020] By adopting the above technical solution, it is easy to remove the filter screen from the filter cylinder, make it easy to empty the garbage in the filter screen, or replace the filter screen.
[0021] Optionally, the inner groove is equipped with a stop.
[0022] By adopting the above technical solution, when the cleaning machine is not in water, the lifting sleeve descends and the lower end of the stop block abuts against the upper edge of the filter screen. When the cleaning machine is in water, the lifting sleeve rises under the buoyancy of the water and the lower end of the stop block leaves the upper edge of the filter screen, thereby preventing the upper edge of the filter screen from getting stuck in the inner groove of the lifting sleeve.
[0023] Optionally, the pumping shell is equipped with a water outlet cylinder, which is connected to the pumping chamber.
[0024] Optionally, water outlets are provided on both the front and rear sides of the pump casing, with the water flowing out of the two sets of water outlets in opposite directions.
[0025] By adopting the above technical solution, when the automatic water surface cleaning machine needs to move forward, the water outlet on the front side is controlled to stop water flow, and water is controlled to flow out from the water outlet on the rear side to push the automatic water surface cleaning machine forward. When the automatic water surface cleaning machine needs to move backward, the water outlet on the rear side is controlled to stop water flow, and water is controlled to flow out from the water outlet on the front side to push the automatic water surface cleaning machine backward.
[0026] In summary, this utility model has at least one of the following beneficial effects:
[0027] When the pump is not running, since A≤B, the lifting sleeve floats in the water. The top of the lifting sleeve is above or level with the water surface, which prevents the debris in the filter screen from overflowing from the opening of the filter device. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.
[0036] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 An embodiment of this utility model provides an automatic water surface cleaning machine to prevent garbage overflow, including a filter device 1 and a water pumping device 3. The filter device 1 includes a filter cylinder 101, a filter screen 102 installed on the filter cylinder 101, an opening 8 at the bottom of the filter cylinder 101, and a lifting sleeve 6, where A≤B, A is the average density of the lifting sleeve 6, and B is the density of water. When the automatic water surface cleaning machine is placed in water, the lifting sleeve 6 can be fitted onto the filter device and raised and lowered.
[0037] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3 The water pumping device is located at the bottom of the filter device. The water pumping device 3 includes a water pumping shell 301 and a water pump 303. The water pumping shell 301 and the filter cylinder 101 form a water pumping chamber 302, and the opening 8 is connected to the water pumping chamber 302.
[0038] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 3 A≥80%B. Since the downward pressure exerted on the lifting sleeve 6 by the flowing water is limited, if the average density of the lifting sleeve 6 is too small, the flowing water cannot push the lifting sleeve 6 below the water surface after the water pump 303 is started. A≥80%B ensures that the average density of the lifting sleeve 6 is within this range, so that the flowing water can push the lifting sleeve 6 below the water surface. The top 10 does not block the garbage from entering the filter screen 102, which is conducive to the garbage entering the filter screen 102 smoothly.
[0039] Please refer to the attached diagram in the instruction manual. Figure 2 , Figure 3 , Figure 4 and Figure 5 The filter screen 102 is fitted onto the filter cylinder 101. The lifting sleeve 6 has a U-shaped longitudinal section, and an inner groove 7 is formed on its upper edge. The lifting sleeve 6 can be fitted onto the filter screen 102 and raised or lowered. The lifting sleeve 6 will not be subject to friction from the upper edge of the filter screen 102, allowing it to float due to the buoyancy of the water (see reference). Figure 3 It can also fall under the downward pressure of water (see reference). Figure 2 (D≤C≤1.2D, where C is the width of the inner groove 7 and D is the width of the upper edge of the filter screen 102. This prevents the lifting sleeve 6 from swaying excessively on the upper edge of the filter screen 102.)
[0040] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 A floating device 2 is connected to the outer wall of the filter cylinder 101. The average density of the floating device 2 is less than that of water, allowing the cleaning machine to float on the water. There are three floating devices 2, which are evenly installed on the outer wall of the filter cylinder 101. This makes the weight of the cleaning machine more balanced on both sides, reduces yaw caused by gravity imbalance, and enhances the stability of the cleaning machine during operation.
[0041] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 3 The upper edge of the filter screen 102 is fitted onto the upper edge of the filter cylinder 101. This makes it easy to remove the filter screen 102 from the filter cylinder 101, making it convenient to empty the debris from the filter screen 102 or replace the filter screen 102.
[0042] Please refer to the attached diagram in the instruction manual. Figure 2 , Figure 3 , Figure 4 and Figure 5 The inner tank 7 has a baffle 9 inside. When the cleaning machine is not in water, such as... Figure 2 The middle lifting sleeve 6 descends, and the lower end of the stop block 9 abuts against the upper edge of the filter screen 102. This occurs when the cleaning machine is in water. Figure 3 The lifting sleeve 6 rises under the buoyancy of the water, and the lower end of the stop block 9 moves away from the upper edge of the filter screen 102, thereby preventing the upper edge of the filter screen 102 from getting stuck in the inner groove 7 of the lifting sleeve 6.
[0043] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 3 The automatic water surface cleaning machine includes a sealed chamber 4 and a water pump 303, which includes two sets of motors. The body parts of the two sets of motors are installed inside the sealed chamber 4. The top of the two sets of motors are connected to a drive shaft, and an impeller is installed at one end of the two sets of drive shafts that extends into the water pumping shell.
[0044] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3 The water pump housing 301 is equipped with a water outlet cylinder 5, which is connected to the water pumping chamber 302. The water flowing out of the water pumping chamber flows through the water outlet cylinder 5 to the outside of the automatic water surface cleaning machine.
[0045] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3The front and rear sides of the water-collecting shell 301 are equipped with water outlet cylinders 5, and the water flowing out of the two sets of water outlet cylinders 5 flows in opposite directions. When the automatic water surface cleaning machine needs to move forward, the water outlet cylinder 5 on the front side is controlled to stop flowing water, and the water flows out from the water outlet cylinder 5 on the rear side, pushing the automatic water surface cleaning machine forward. When the automatic water surface cleaning machine needs to move backward, the water outlet cylinder 5 on the rear side is controlled to stop flowing water, and the water flows out from the water outlet cylinder 5 on the front side, pushing the automatic water surface cleaning machine backward.
[0046] Working principle: When in use, the automatic water surface cleaner is placed on the water surface to be cleaned. Through the cooperation of the three floating devices 2, the cleaner floats on the surface. Then, the water pump 303 is started. The garbage floating on the water surface near the filter device 1 flows into the filter cylinder 101 with the water flow and is intercepted by the filter screen 102, thus facilitating the unified collection of garbage on the water surface. Water enters the interior of the pumping chamber 302 through the opening 8. The water pump 303 drains the water that has entered the filter screen 102 through the water outlet 5. The water flowing out of the water outlet 5 propels the automatic water surface cleaner to move on the water surface. In this way, water continuously flows from the opening of the filter cylinder 101 into the filter screen 102, and the water entering the filter screen 102 is continuously drained by the water pump 303. After the filter screen 102 has collected a certain amount of garbage, it can be cleaned.
[0047] At the same time, as the water around the automatic water surface cleaning machine flows to the filter screen 102, the water exerts downward pressure on the lifting sleeve 6, such as... Figure 2 At this time, the lifting sleeve 6 descends, so the top 10 of the lifting sleeve 6 is lower than the water surface. The top 10 does not block the garbage from entering the filter screen 102, which is conducive to the garbage entering the filter screen 102 smoothly.
[0048] When pump 303 is not started, since A≤B, where A is the average density of lifting sleeve 6 and B is the density of water, ... Figure 3 When the lifting sleeve 6 is raised, the top 10 of the lifting sleeve 6 is above or level with the water surface, thereby preventing the debris in the filter screen 102 from overflowing from the opening of the filter screen 102.
[0049] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
