Description

Technical Field

[0001] The present application relates to the field of robotics, and in particular to a pool cleaning robot. Background Art

[0002] A pool cleaning robot is a robot that can clean a pool. Typically, a filter cartridge is installed inside the robot. When the robot is operating, water from outside can enter the robot, be filtered by the filter cartridge, and then be discharged through an outlet on the robot.

[0003] The filter box is equipped with a filter. After the pool cleaning robot has been running for a period of time, the filter is prone to clogging, especially in pools with a lot of flocs. The clogged filter will cause the pool cleaning robot's ability to absorb pollutants to decrease. Therefore, the filter box filter needs to be cleaned regularly.

[0004] Currently, the cleaning of the filter is usually done manually, and the filter box needs to be removed from the body before the filter can be cleaned. This results in low cleaning efficiency and increases the burden on people, which affects the user experience. Utility Model Content

[0005] The present application provides a pool cleaning robot, which aims to improve the cleaning efficiency of the filter and reduce the burden on people, thereby improving the user experience.

[0006] The specific technical solutions are as follows:

[0007] An embodiment of the present application provides a pool cleaning robot, which includes: a body, an installation cavity is provided inside the body, and the body is provided with a water inlet and a water outlet connected to the installation cavity; a filter box, the filter box is provided in the installation cavity, and the filter box has a filter screen; a water flow drive device, the water flow drive device is provided in the installation cavity, the water flow drive device has a first mode and a second mode, when the water flow drive device is in the first mode, it drives the water in the installation cavity to flow from the water inlet to the water outlet, and when the water flow drive device is in the second mode, it drives the water in the installation cavity to flow from the water outlet to the water inlet; and a flushing device, the flushing device is located between the water flow drive device and the filter box, and the flushing device is provided with a plurality of drainage holes arranged toward the filter screen.

[0008] In an embodiment of the present application, a pool cleaning robot is provided with an installation cavity within its body, wherein a filter cartridge and a water flow drive device are disposed within the installation cavity. When the water flow drive device is in a first mode, the water flow drive device provides a suction force, causing external water to enter the installation cavity through the water inlet and be discharged through the water outlet after passing through the filter cartridge, thereby cleaning the pool. Furthermore, a flushing device is provided within the installation cavity, the flushing device being located between the water flow drive device and the filter cartridge. When the water flow drive device is in a second mode, the water flow drive device provides a suction force, the direction of which is opposite to the direction of the suction force in the first mode. Under the action of this suction force, external water enters the installation cavity through the water outlet and flows toward the water inlet. As the water flows within the installation cavity, it is discharged through the drainage holes of the flushing device and flushes the filter screen of the filter cartridge, thereby flushing away debris attached to the filter screen. Thus, the pool cleaning robot maintains a good sewage suction capacity.

[0009] Since the pool cleaning robot can flush the filter by adjusting the working mode of the water flow drive device, compared with the manual cleaning method of the filter, it eliminates the process of disassembling and cleaning the filter box, so it has higher cleaning efficiency. In addition, it can also reduce the burden on people, thereby improving the user experience.

[0010] In some embodiments of the present application, the water flow drive device includes a motor and an impeller, and the output shaft of the motor is connected to the impeller; wherein, the rotation direction of the motor when the water flow drive device is in the first mode is opposite to the rotation direction of the motor when the water flow drive device is in the second mode.

[0011] The output shaft of the motor is connected to the impeller, and the motor can drive the impeller to rotate. By adjusting the rotation direction of the motor and the impeller, the first mode and the second mode of the water flow drive device can be switched.

[0012] In some embodiments of the present application, the flushing device includes a mounting baffle and a plurality of nozzles arranged on the mounting baffle, each nozzle being provided with a drainage hole; the mounting baffle is located between the water flow driving device and the filter box, and is connected to the fuselage.

[0013] The mounting baffle is located between the water drive unit and the filter cartridge. It blocks the flow of water, meaning the only path for water to flow through the flushing unit is the drain hole. This allows the water to flow through the drain hole at a higher velocity, improving the flushing capability of the filter.

[0014] In some embodiments of the present application, the drainage hole has a first aperture at one end close to the water flow driving device, and has a second aperture at one end close to the filter box, and the first aperture is larger than the second aperture.

[0015] When the water flow drive device is in the second mode, the water flow drive device operates to draw external water into the mounting cavity through the water outlet and drain toward the filter through the drain hole. Because the first aperture of the drain hole, located near the end of the water flow drive device, is larger than the second aperture near the end of the filter cartridge, water flow is accelerated as it passes through the drain hole, thereby further increasing the velocity of the water as it is discharged through the drain hole, thereby further improving the flushing capability of the filter.

[0016] In some embodiments of the present application, a plurality of the nozzles are arranged in an array.

[0017] Such an arrangement can expand the distribution range of the nozzles, thereby expanding the flushing range of the filter, which is conducive to a more comprehensive cleaning of the filter.

[0018] In some embodiments of the present application, the mounting baffle is provided with a water hole; the flushing device also includes a one-way mechanism arranged at the water hole; when the water flow driving device is in the first mode, the one-way mechanism is opened to allow water to flow through the water hole; when the water flow driving device is in the second mode, the one-way mechanism is closed to block the water hole.

[0019] When the water flow drive device is in the first mode, external water enters the mounting cavity through the water inlet, passes through the filter cartridge, and is discharged through the water outlet to clean the pool. In the first mode, the one-way mechanism is open, revealing the water holes on the mounting baffle. This increases the water flow rate, thereby improving the cleaning efficiency of the pool cleaning robot. When the water flow drive device is in the second mode, external water enters the mounting cavity through the water outlet and flows in the reverse direction. At this time, the one-way mechanism is closed, blocking the water holes, allowing water to be discharged only through the drain hole. This increases the flow rate of water when it is discharged through the drain hole, thereby improving the water flow's ability to flush the filter.

[0020] In some embodiments of the present application, the one-way mechanism includes a water baffle, the area of ​​the water baffle is larger than the area of ​​the water hole, and the water baffle is located on the side of the installation baffle away from the filter box; the water baffle is a rubber plate or a silicone plate, and one side edge of the water baffle is connected to the installation baffle.

[0021] When the water flow driving device is in the second mode, the water flow entering the installation cavity through the water outlet flows toward the installation baffle. Under the action of the water flow, the water baffle will fit more tightly with the installation baffle and keep covering the water hole. As a result, the water baffle can block the water hole so that the water flow can only be discharged through the drainage hole, thereby increasing the flow rate of the water when it is discharged through the drainage hole, so as to improve the water flow's ability to flush the filter screen.

[0022] When the water flow driving device is in the first mode, the water flow entering the installation cavity through the water inlet passes through the filter box and then flows to the installation baffle. Under the impact of the water flow, the water baffle separates from the installation baffle and deforms, so that the water hole is exposed, so that the water flow can flow through the water hole, thereby increasing the water flow rate to improve the cleaning efficiency of the pool cleaning robot.

[0023] In some embodiments of the present application, there are multiple water holes, and each water hole is provided with a one-way mechanism.

[0024] There are multiple water holes. When the water flow drive device is in the first mode, water can flow through multiple water holes simultaneously, thereby further increasing the water flow rate and thus further improving the cleaning efficiency of the pool cleaning robot. In addition, each water hole is provided with a one-way mechanism. When the water flow drive device is in the second mode, all water holes are blocked by the one-way mechanism, so that water can only be discharged through the drain hole.

[0025] In some embodiments of the present application, the flushing device is connected to the body in a detachable manner, so that the flushing device can be easily removed for inspection and maintenance.

[0026] In some embodiments of the present application, the flushing device includes a mounting baffle and a plurality of nozzles arranged on the mounting baffle, each of the nozzles is provided with one of the drainage holes; the mounting baffle includes a plate body and a mounting portion arranged on the edge of the plate body; a limiting protrusion is provided on the side wall of the fuselage, the limiting protrusion defines a mounting groove, the mounting groove extends along the height direction of the pool cleaning robot, and the mounting portion can be inserted into the mounting groove in a plug-in manner.

[0027] The mounting groove extends along the height direction of the pool cleaning robot, and the mounting portion can be inserted into the mounting groove in a plug-in manner, so that the flushing device is detachable relative to the body, and the installation method of the flushing device is simple and easy to operate, which is conducive to improving the disassembly and assembly efficiency of the flushing device.

Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0043] A pool cleaning robot is a robot that can clean a pool. Typically, a filter cartridge is installed inside the robot. When the robot is operating, water from outside can enter the robot, be filtered by the filter cartridge, and then be discharged through an outlet on the robot.

[0044] The filter box is equipped with a filter. After the pool cleaning robot has been running for a period of time, the filter is prone to clogging, especially in pools with a lot of flocs. The clogged filter will cause the pool cleaning robot's ability to absorb pollutants to decrease. Therefore, the filter box filter needs to be cleaned regularly.

[0045] Currently, the cleaning of the filter is usually done manually, and the filter box needs to be removed from the body before the filter can be cleaned. This results in low cleaning efficiency and increases the burden on people, which affects the user experience.

[0046] Based on the above situation, an embodiment of the present application provides a pool cleaning robot, which aims to improve the cleaning efficiency of the filter and reduce the burden on people, thereby improving the user experience.

[0047] Figure 1 This is a schematic diagram of the structure of a pool cleaning robot provided in one embodiment of the present application. Figure 2 This is an exploded diagram of a pool cleaning robot provided in one embodiment of the present application. Figure 3 This is a schematic diagram of the structure of a flushing device provided in one embodiment of the present application. Figure 1 、 Figure 2 as well as Figure 3As shown, the pool cleaning robot 10 provided in an embodiment of the present application includes a body 100, a filter box 200, a water flow drive device 300, and a flushing device 400. The body 100 is provided with an installation cavity 110 inside, and the body 100 is provided with a water inlet 120 and a water outlet 130 connected to the installation cavity 110. The filter box 200 is provided in the installation cavity 110, and the filter box 200 has a filter screen (not shown in the figure). The water flow drive device 300 is provided in the installation cavity 110, and the water flow drive device 300 has a first mode and a second mode. When the water flow drive device 300 is in the first mode, the water in the installation cavity 110 is driven to flow from the water inlet 120 to the water outlet 130. When the water flow drive device 300 is in the second mode, the water in the installation cavity 110 is driven to flow from the water outlet 130 to the water inlet 120. The flushing device 400 is located between the water flow driving device 300 and the filter box 200 . The flushing device 400 is provided with a plurality of drainage holes 421 arranged toward the filter screen.

[0048] The pool cleaning robot 10 in the embodiment of the present application has an installation cavity 110 provided inside the body 100, and the filter box 200 and the water flow drive device 300 are arranged in the installation cavity 110. When the water flow drive device 300 is in the first mode, the water flow drive device 300 can provide suction force, so that external water enters the installation cavity 110 through the water inlet 120, and is discharged from the water outlet 130 after passing through the filter box 200, so that the pool can be cleaned.

[0049] On this basis, a flushing device 400 is also provided in the installation cavity 110, and the flushing device 400 is located between the water flow driving device 300 and the filter box 200. When the water flow driving device 300 is in the second mode, the water flow driving device 300 can provide a suction force, and the direction of the suction force is opposite to the direction of the suction force in the first mode. Under the action of the suction force, external water enters the installation cavity 110 through the water outlet 130 and flows to the water inlet 120. During the flow of water in the installation cavity 110, it will be discharged through the drainage hole 421 of the flushing device 400, and form a flushing effect on the filter net of the filter box 200. The flushing effect can be used to flush away debris attached to the filter net. In this way, the pool cleaning robot 10 can maintain a good sewage suction ability.

[0050] Since the pool cleaning robot 10 can flush the filter by adjusting the working mode of the water flow drive device 300, compared with the manual cleaning method of the filter, the process of disassembling and cleaning the filter box 200 is eliminated, so it has higher cleaning efficiency. In addition, it can also reduce the burden on people, thereby improving the user experience.

[0051] like Figure 1As shown, in some embodiments, the water flow driving device 300 includes a motor 310 and an impeller 320, and the output shaft of the motor 310 is connected to the impeller 320. The rotation direction of the motor 310 when the water flow driving device 300 is in the first mode is opposite to the rotation direction of the motor 310 when the water flow driving device 300 is in the second mode.

[0052] The output shaft of motor 310 is connected to impeller 320, and motor 310 can drive impeller 320 to rotate. By adjusting the rotation direction of motor 310 and impeller 320, water flow drive device 300 can be switched between the first mode and the second mode. In a specific example, when motor 310 drives impeller 320 to rotate forward, water flow drive device 300 is in the first mode. When motor 310 drives impeller 320 to rotate counterclockwise, water flow drive device 300 is in the second mode.

[0053] like Figure 1 、 Figure 3 As shown, in some embodiments, the flushing device 400 includes a mounting baffle 410 and a plurality of nozzles 420 arranged on the mounting baffle 410, each nozzle 420 is provided with a drainage hole 421, and the mounting baffle 410 is located between the water flow driving device 300 and the filter box 200, and is connected to the fuselage 100.

[0054] The mounting baffle 410 is disposed between the water flow drive device 300 and the filter cartridge 200. The mounting baffle 410 serves to block the water flow. In other words, the only path for water flow through the flushing device 400 is the drainage hole 421. This allows the water to flow at a higher velocity after being discharged through the drainage hole 421, thereby improving the flushing capability of the filter.

[0055] In one embodiment, the end of the drainage hole 421 close to the water flow driving device 300 has a first aperture, and the end of the drainage hole 421 close to the filter box 200 has a second aperture, and the first aperture is larger than the second aperture.

[0056] When the water flow drive device 300 is in the second mode, external water enters the installation cavity 110 through the water outlet 130 under the action of the water flow drive device 300 and is discharged toward the filter through the drainage hole 421. Because the first aperture of the drainage hole 421 near the end of the water flow drive device 300 is larger than the second aperture near the end of the filter cartridge 200, the water flow is accelerated during the process of passing through the drainage hole 421, thereby further increasing the flow rate of the water when it is discharged through the drainage hole 421, thereby further improving the flushing ability of the filter.

[0057] like Figure 3As shown, in one embodiment, a plurality of nozzles 420 are arranged in an array. This arrangement can expand the distribution range of the nozzles 420, thereby expanding the flushing range of the filter, which is conducive to a more comprehensive cleaning of the filter.

[0058] Figure 4 This is a schematic structural diagram of a flushing device provided in another embodiment of the present application. Figure 5 This is a schematic diagram of the structure of the flushing device provided in another embodiment of the present application from another perspective. Figure 4 、 Figure 5 As shown, in some embodiments, the mounting baffle 410 is provided with a water hole 411, and the flushing device 400 further includes a one-way mechanism 430 provided at the water hole 411. When the water flow driving device 300 is in the first mode, the one-way mechanism 430 is open, allowing water to flow through the water hole 411; when the water flow driving device 300 is in the second mode, the one-way mechanism 430 is closed, thereby blocking the water hole 411.

[0059] When the water flow drive device 300 is in the first mode, external water enters the installation cavity 110 through the water inlet 120, passes through the filter box 200, and is discharged from the water outlet 130 to clean the pool. In the first mode, the one-way mechanism 430 is open, and the water hole 411 on the mounting baffle 410 is exposed. This increases the flow rate of the water flow, thereby improving the cleaning efficiency of the pool cleaning robot 10. When the water flow drive device 300 is in the second mode, external water enters the installation cavity 110 through the water outlet 130 and flows in the reverse direction. At this time, the one-way mechanism 430 is closed, blocking the water hole 411, so that the water flow can only be discharged through the drain hole 421. This helps to increase the flow rate of the water when it is discharged through the drain hole 421, thereby improving the water flow's ability to flush the filter screen.

[0060] like Figure 4 、 Figure 5 As shown, in one embodiment, the one-way mechanism 430 includes a water baffle 431. The area of ​​the water baffle 431 is larger than the area of ​​the water hole 411. The water baffle 431 is located on the side of the mounting baffle 410 facing away from the filter box 200. The water baffle 431 is a rubber plate or a silicone plate, and one side edge of the water baffle 431 is connected to the mounting baffle 410.

[0061] The area of ​​the water baffle 431 is larger than the area of ​​the water hole 411, so that the water baffle 431 can cover the water hole 411. The water baffle 431 is arranged on the side of the installation baffle 410 away from the filter box 200. In this way, when the water flow driving device 300 is in the second mode, the water flow entering the installation cavity 110 through the water outlet 130 flows toward the installation baffle 410. Under the action of the water flow, the water baffle 431 will fit more closely with the installation baffle 410 and maintain coverage of the water hole 411. As a result, the water baffle 431 can block the water hole 411, so that the water flow can only be discharged through the drainage hole 421, thereby increasing the flow rate of the water when it is discharged through the drainage hole 421, so as to improve the water flow's ability to flush the filter screen. In addition, since the water baffle 431 is a rubber plate or a silicone plate, the water baffle 431 is made of a soft material. In this way, a better sealing effect can be formed when the water baffle 431 is fitted with the mounting baffle 410 .

[0062] When the water flow driving device 300 is in the first mode, the water flow entering the installation cavity 110 through the water inlet 120 passes through the filter box 200 and flows to the installation baffle 410. Under the impact of the water flow, the water baffle 431 separates from the installation baffle 410 and deforms, so that the water hole 411 is exposed, so that the water flow can flow through the water hole 411, thereby increasing the flow rate of the water flow and improving the cleaning efficiency of the pool cleaning robot 10.

[0063] like Figure 4 、 Figure 5 As shown, in one embodiment, there are multiple water holes 411, and each water hole 411 is provided with a one-way mechanism 430. The multiple water holes 411 allow water to flow through multiple water holes 411 simultaneously when the water flow drive device 300 is in the first mode, thereby further increasing the water flow rate and thus the cleaning efficiency of the pool cleaning robot 10. Furthermore, each water hole 411 is provided with a one-way mechanism 430. Thus, when the water flow drive device 300 is in the second mode, all water holes 411 can be blocked by the closed one-way mechanisms 430, allowing water to be discharged only through the drain hole 421.

[0064] In some embodiments, the flushing device 400 is detachably connected to the body 100. This facilitates the removal of the flushing device 400 for inspection and maintenance.

[0065] like Figure 1 、 Figure 2 as well as Figure 3As shown, in one embodiment, the flushing device 400 includes a mounting baffle 410 and a plurality of nozzles 420 disposed on the mounting baffle 410, each nozzle 420 being provided with a drainage hole 421. The mounting baffle 410 includes a plate body 412 and a mounting portion 413 disposed on an edge of the plate body 412. The sidewall of the body 100 is provided with a limiting protrusion 140, which defines a mounting slot. The mounting slot extends along the height direction of the pool cleaning robot 10, and the mounting portion 413 can be inserted into the mounting slot.

[0066] There may be multiple limiting protrusions 140 , and two adjacent limiting protrusions 140 may jointly define a mounting groove.

[0067] The mounting baffle 410 includes a plate body 412 and a mounting portion 413 disposed on an edge of the plate body 412. The nozzle 420 is disposed on the plate body 412. Two mounting portions 413 may be provided, one on each of two opposing edges of the plate body 412. A mounting slot extends along the height of the pool cleaning robot 10, and the mounting portion 413 can be inserted into the mounting slot. This allows the flushing device 400 to be detachable relative to the body 100. Furthermore, the flushing device 400 is simple to install and easy to operate, thereby improving the efficiency of its assembly and disassembly.

[0068] The above content is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
