Description

Technical Field

[0001] This utility model relates to the technical field of automatic water surface cleaning machines, and in particular to a filtration device and an automatic water surface cleaning machine for preventing garbage from escaping. 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: the debris that enters the filter screen can escape from the filter screen and return to the water surface. For example, if the pump of the automatic water surface cleaning machine is not running or the pump power is low, the suction force of the pump is zero or reduced, and the debris in the filter screen is easy to float to the top and escape, which reduces the cleaning efficiency of the automatic water surface cleaning machine. Utility Model Content

[0004] In order to improve the problem mentioned above in the prior art where the garbage entering the filter screen of the automatic water surface cleaner escapes from the filter screen and returns to the water surface, reducing the cleaning efficiency of the automatic water surface cleaner, this utility model provides a filter device and an automatic water surface cleaner to prevent garbage from escaping.

[0005] This utility model provides a filtration device to prevent garbage escape and an automatic water surface cleaning machine, adopting the following technical solution:

[0006] A filtration device for preventing garbage escape includes a filter cylinder and a filter screen, the filter screen being located on the filter cylinder, and the bottom of the filter cylinder having an opening including an escape-proof surface, the escape-proof surface being installed at the opening of the filtration device.

[0007] By adopting the above technical solution, during the process of water flowing around the automatic water surface cleaner to the filter screen, the garbage falls into the inside of the filter screen after reaching the anti-escape surface. When the water pump is not started or the water pump power is low, the suction of the water pump is zero or reduced, and the anti-escape surface prevents the garbage inside the filter screen from escaping to the top of the anti-escape surface, thereby improving the cleaning efficiency of the automatic water surface cleaner.

[0008] Optionally, a sleeve is included, which is fitted onto the filter screen, and the escape-proof surface is installed on the inner side of the sleeve.

[0009] By adopting the above technical solution, it is easy to separate the sleeve from the filter screen, thereby facilitating the cleaning of the anti-escape surface.

[0010] Optionally, a mounting platform is provided on the inner side of the sleeve, and the outer side of the escape-proof surface is mounted on the mounting platform.

[0011] Optionally, a pressure plate is included, which is detachably connected to the mounting platform, and the clips on the pressure plate are pressed into holes on the mounting platform;

[0012] The escape-proof surface is detachably connected to the mounting platform, and the protrusion on the mounting platform is inserted into the hole of the escape-proof surface.

[0013] By adopting the above technical solution, the outer side of the anti-escape surface can be pressed onto the mounting platform by pressing the plate, thereby ensuring that the anti-escape surface is fixed.

[0014] Optionally, the material of the escape-proof surface is a flexible material.

[0015] By adopting the above technical solution, when the garbage reaches the escape-proof surface, the escape-proof surface deforms under the gravity of the garbage, causing the escape-proof surface to tilt downwards. The garbage slides down the downward-tilting escape-proof surface after deformation and falls into the interior of the filter screen.

[0016] Optionally, the escape prevention surface includes two or more surface units.

[0017] By adopting the above technical solution, and through the cooperation of multiple surface units, it is easier to deform under the gravity of the waste, and it is more conducive to the anti-escape surface tilting downwards.

[0018] Optionally, the filter screen is fitted onto the filter cylinder, and a handle is provided at the center of the top of the filter screen.

[0019] By adopting the above technical solution, it is easy to remove the filter screen from the filter cartridge and clean the filter screen. At the same time, the handle makes it easy for the user to lift the filter screen and remove it from the filter cartridge.

[0020] Optionally, a filter layer, which is a sponge filter layer, is placed in the cavity between the filter cylinder and the filter screen.

[0021] By adopting the above technical solution, the water passing through the filter screen is filtered through the filter layer before leaving the outlet, making the water quality purer.

[0022] Automatic water surface cleaning machine, including the aforementioned filter device to prevent garbage escape.

[0023] Optionally, a water pumping device is included, which is located at the bottom of the filter device. The water pumping device includes a water pumping shell and a water pump. A water pumping chamber is formed between the water pumping shell and the filter cylinder. The opening is connected to the water pumping chamber. Water outlet cylinders are provided on both sides of the water pumping shell. The water outlet cylinders are connected to the water pumping chamber.

[0024] Optionally, it also includes a sealed chamber. The pump includes two sets of motors. The body parts of the two sets of motors are installed inside the sealed chamber. The top of the two sets of motors are connected to a drive shaft. An impeller is installed at one end of the two sets of drive shafts that extends into the pumping shell.

[0025] Optionally, a flotation device is also included, which is mounted on the sleeve and includes four flotation units.

[0026] By adopting the above technical solution, the automatic water surface cleaner is placed on the water surface to be cleaned. Through four floating units, the cleaner floats on the surface. Then, the water pump is started. The garbage floating on the water surface near the filter device flows into the filter cylinder with the water flow and is intercepted by the filter screen, thus facilitating the unified collection of garbage on the water surface. Water enters the interior of the pumping chamber through the opening. The water pump discharges the water that has entered the filter screen through the water outlet. The water flowing out of the water outlet propels the automatic water surface cleaner to move on the water surface.

[0027] In summary, this utility model has at least one of the following beneficial effects:

[0028] By installing the escape-proof surface at the opening of the filter device, when the garbage reaches the escape-proof surface, the escape-proof surface tilts downwards, and the garbage slides down the deformed, downward-tilting escape-proof surface and falls into the inside of the filter screen. When the water pump is not running or the water pump power is low, the escape-proof surface prevents the garbage inside the filter screen from escaping to the top of the escape-proof surface, thus improving the cleaning efficiency of the automatic water surface cleaning machine.

[0029] By placing a sponge filter layer in the cavity between the filter screen and the filter cylinder, the water passing through the filter screen passes through the sponge filter layer before exiting the outlet, thus making the water purer. Attached Figure Description

[0043] The following is in conjunction with the appendix Figures 1-11 The present invention will be described in further detail below.

[0044] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2An embodiment of this utility model provides a filter device for preventing garbage escape, including a filter cylinder 5 and a filter screen 11. The filter screen 11 is located on the filter cylinder 5. The bottom of the filter cylinder 5 has an opening 10, including an anti-escape surface 4, which is installed at the opening of the filter device.

[0045] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 7 The system includes a sleeve 2, which is fitted onto the filter screen 11, with an anti-escape surface 4 installed inside the sleeve 2. This facilitates the separation of the sleeve 2 from the filter screen 11, making it easier to clean the anti-escape surface 4.

[0046] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 8 The sleeve 2 has an inner mounting platform 14, and the outer side of the anti-escape surface 4 is mounted on the mounting platform 14. A pressure plate 13 is included, which is detachably connected to the mounting platform 14. A clip 15 on the pressure plate 13 is pressed into a hole on the mounting platform 14. The anti-escape surface 4 is also detachably connected to the mounting platform 14, and a protrusion 17 on the mounting platform 14 is inserted into a hole in the anti-escape surface 4. This allows the pressure plate 13 to press the outer side of the anti-escape surface 4 onto the mounting platform 14, thus ensuring that the anti-escape surface 4 is fixed.

[0047] Please refer to the attached diagram in the instruction manual. Figure 1 The material of the escape-proof surface 4 is a flexible material. When the garbage reaches the escape-proof surface 4, the escape-proof surface 4 deforms under the gravity of the garbage, causing the escape-proof surface 4 to tilt downward. The garbage slides down the deformed and downward tilted escape-proof surface 4 and falls into the interior of the filter screen 11.

[0048] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 3 , Figure 4 and Figure 6 The escape-proof surface 4 includes two or more surface units 401. Through the cooperation of multiple surface units 401, it is easier to deform under the gravity of the waste, and it is more conducive to the downward tilting of the escape-proof surface 4.

[0049] Please refer to the attached diagram in the instruction manual. Figure 2 , Figure 4 and Figure 7 The filter screen 11 is fitted onto the filter cylinder 5, and a handle 12 is provided at the center of the top of the filter screen 11. This makes it easy to remove the filter screen 11 from the filter cylinder 5 and clean it. At the same time, the handle 12 makes it easy for the user to lift the filter screen 11 and remove it from the filter cylinder 5.

[0050] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 7 A filter layer 16, which is a sponge filter layer, is placed in the cavity between the filter cylinder 5 and the filter screen 11. In this way, the water passing through the filter screen 11 is filtered by the filter layer 16 before exiting the outlet, making the water purer.

[0051] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 7 and Figure 8 Automatic water surface cleaning machine, including the aforementioned filter device to prevent garbage escape.

[0052] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 It includes a water pumping device, which is located at the bottom of the filter device. The water pumping device includes a water pumping shell 1 and a water pump. The water pumping shell 1 and the filter cylinder 5 form a water pumping chamber 9. The opening 10 is connected to the water pumping chamber 9. Water outlet cylinders 7 are provided on both sides of the water pumping shell 1 and are connected to the water pumping chamber 9.

[0053] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 Specifically, it also includes a sealed chamber. The pump includes two sets of motors 8. The body parts of the two sets of motors 8 are installed inside the sealed chamber. The top of the two sets of motors 8 are connected to a drive shaft. The end of the two sets of drive shafts that extends into the pump casing 1 is equipped with an impeller 6.

[0054] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 8 Specifically, it also includes a floating device, which is installed on the sleeve 2 and includes four floating units 3. The automatic water surface cleaner is placed on the water surface to be cleaned, and the four floating units 3 make the cleaner float on it. Then, the water pump is started, and the garbage floating on the water surface near the filter device flows into the filter cylinder 5 with the water flow and is intercepted by the filter screen 11, thus facilitating the unified collection of garbage on the water surface. Water enters the interior of the pumping chamber 9 through the opening 10, and the water pump discharges the water that has entered the filter screen 11 through the water outlet 7. The water flow from the water outlet 7 propels the automatic water surface cleaner to move on the water surface.

[0055] Working principle: When in use, the automatic water surface cleaner is placed on the water surface to be cleaned. Through the four floating units 3, the cleaner floats on the surface. Then, the water pump is started. The garbage floating on the water surface near the filter device flows into the filter cylinder 5 with the water flow and is intercepted by the filter screen 11, thus facilitating the collection of garbage on the water surface. Water enters the pumping chamber 9 through the opening 10. The water pump drains the water that has entered the filter screen 11 through the water outlet 7. The water flowing out of the water outlet 7 propels the automatic water surface cleaner to move on the water surface. In this way, water continuously flows from the opening 10 of the filter cylinder 5 into the filter screen 11, and the water entering the filter screen 11 is continuously drained by the water pump. After the filter screen 11 has collected a certain amount of garbage, it can be cleaned.

[0056] Meanwhile, as the water around the automatic water surface cleaner flows to the filter screen 11, the garbage falls into the interior of the filter screen 11 after reaching the anti-escape surface 4. When the water pump is not started or the water pump power is low, the suction of the water pump is zero or reduced. At this time, the anti-escape surface 4 prevents the garbage inside the filter screen 11 from escaping to the top of the anti-escape surface 4, thus improving the cleaning efficiency of the automatic water surface cleaner.

[0057] When installing the escape prevention surface 4, the escape prevention surface 4 can be installed on the mounting platform 14 first. The protrusion 17 on the mounting platform 14 is inserted into the hole of the escape prevention surface 4. Then, the buckle 15 on the pressure plate 13 is pressed into the hole on the mounting platform 14. At this time, the pressure plate 13 presses the outer side of the escape prevention surface 4 onto the mounting platform 14, and the escape prevention surface 4 is fixed. When removing the escape prevention surface 4, the buckle 15 is pushed out from the hole on the mounting platform 14. The pressure plate 13 can be removed from the mounting platform 14 first, and then the hole on the escape prevention surface 4 can be disengaged from the protrusion 17 on the mounting platform 14 to remove the escape prevention surface 4.

[0058] When it is necessary to clean the debris inside the filter screen 11, place the cleaning machine on the shore, remove the sleeve 2 by hand, and use a water hose to rinse the escape-proof surface 4 (see the attached diagram in the instruction manual). Figure 9 Hold the handle 12 close to the filter cylinder 5, then remove the filter screen 11 from inside the filter cylinder 5 and clean the filter screen 11 (see the attached diagram in the instruction manual). Figure 10 Then remove the filter layer 16 from the filter cylinder 5 and rinse the dirt on the filter layer 16 with clean water (see the attached diagram in the instruction manual). Figure 11 ).

[0059] 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.
