Abstract
Description
Technical Field
[0001] This application relates to the field of robotics, and in particular to a filtration device and a water tank cleaning robot system. Background Technology
[0002] A pool cleaning robot is a robot capable of performing cleaning tasks in pools. Typically, pool cleaning robots have a filtration system inside their body. During operation, the filtration system collects dirt and debris from the pool. When a large amount of dirt has accumulated, the filtration system needs to be cleaned.
[0003] One type of pool cleaning robot in the related technology is equipped with a base station capable of recovering dirt from a filtration device. During operation in a pool, when the filtration device has collected a significant amount of dirt, the robot returns to the base station and connects. At this point, a connector on the base station extends into the inlet of the filtration device, and simultaneously, a suction pump equipped on the base station activates, sucking the dirt from the filtration device through the connector.
[0004] However, practice has shown that even after the suction pump operates, a significant amount of dirt remains in the filter, meaning the pump cannot completely remove all the dirt. Therefore, reducing dirt residue is a problem worthy of further research. Utility Model Content
[0005] This application provides a filtration device and a pool cleaning robot system, the purpose of which is to reduce the amount of dirt residue in the filtration device during the dirt recovery process.
[0006] The specific technical solution is as follows:
[0007] An embodiment of the first aspect of this application provides a filtering device, the filtering device comprising: a housing, the housing including a first housing and a second housing connected to the first housing, the first housing having a receiving space, the second housing covering an opening of the receiving space; wherein the first housing converges and extends from an end near the second housing to an end away from the second housing.
[0008] In this embodiment of the filtration device, when the pool cleaning robot is connected to the base station, the bottom wall of the first housing is positioned downwards. Because the first housing converges from the end closer to the second housing to the end farther away from the second housing, dirt accumulates in the narrower area formed after the convergence. When the base station's suction pump operates, the accumulated dirt can be easily sucked away by the pump's suction action. This facilitates more thorough dirt recovery from the filtration device and reduces dirt residue in the filtration device.
[0009] In some embodiments, the first housing extends in a converging manner, forming a first end face at the end of the first housing (110) away from the opening, the area of the first end face being smaller than the area of the opening. Thus, when the pool cleaning robot is connected to the base station, dirt accumulates at the first end face, making it more concentrated and easier to remove.
[0010] In some embodiments, the first end face is positioned approximately opposite to the center of the second housing. This arrangement ensures that the first end face is approximately opposite to the center of the opening of the first housing. When the pool cleaning robot is connected to the base station, this facilitates the accumulation of dirt from various locations within the containment space towards the first end face under the influence of gravity.
[0011] In some embodiments, the first housing includes a sidewall and a bottom wall connected to the sidewall. The sidewall is disposed adjacent to the second housing, and the bottom wall is disposed opposite to the second housing. The sidewall has a water inlet. The bottom wall has a recessed portion extending away from the second housing, and the first end face is formed in the recessed portion. By providing a recess in the bottom wall, it is relatively easy to construct a shape in which the first housing converges and extends from one end closer to the second housing towards the end farther from the second housing, thereby satisfying the requirement for dirt to collect on the first end face.
[0012] In some embodiments, the bottom wall includes a first wall panel and a second wall panel. Multiple first wall panels are arranged around the second wall panel, and the second wall panel is connected to the multiple first wall panels. The side of the second wall panel facing the opening forms the first end face. The included angle between the first wall panel and the second wall panel is greater than or equal to 90° and less than 180°. This arrangement allows the first and second wall panels to create a recessed portion in the bottom wall of the first housing that extends away from the second housing, thereby achieving the effect of allowing dirt to accumulate in the recessed portion 1121 of the bottom wall.
[0013] In some embodiments, the included angle between the first wall panel and the second wall panel is greater than or equal to 120° and less than or equal to 160°. When the above conditions are met, the accumulation of dirt in the recess is more effective, and the volume of the filter device is not excessive.
[0014] In some embodiments, the filtration device further includes a drainage channel connected to the first housing and communicating with the inner cavity of the housing; the first housing includes a side wall and a bottom wall connected to the side wall, the side wall having a water inlet, a first end of the drainage channel located at the water inlet, and a second end of the drainage channel extending to approximately opposite the converging extension end of the first housing. When the pool cleaning robot is connected to a base station, the interface on the base station can extend into the drainage channel through the water inlet. Since the second end of the drainage channel extends to approximately opposite the converging extension end of the first housing, this configuration allows the base station's suction pump to more easily remove dirt accumulated at the converging extension end of the first housing through the drainage channel when the pump is operating, thereby facilitating more thorough dirt recovery in the filtration device and further reducing dirt residue in the filtration device.
[0015] In some embodiments, the first housing converges and extends to form a first end face at the end of the first housing away from the opening, the area of the first end face being smaller than the area of the opening; the second end of the drainage channel extends toward the first end face and faces the first end face. With this configuration, when the pool cleaning robot is connected to the base station, dirt accumulates at the first end face, and the second end of the drainage channel extends toward and faces the first end face. This allows dirt at the first end face to be more easily sucked away through the drainage channel, thereby facilitating more thorough recovery of dirt from the filtration device.
[0016] In some embodiments, the difference between the opening area of the second end of the drainage channel and the area of the first end face is less than or equal to 20% of the area of the first end face. This arrangement ensures that the opening area of the second end of the drainage channel is approximately equal to the area of the first end face. This avoids both situations where the opening area of the drainage channel is too small, making it prone to blockage, and where the opening area is too large, resulting in a low flow velocity and thus affecting the efficiency of waste recovery.
[0017] In some embodiments, the difference between the opening area of the second end of the drainage channel and the area of the first end face is less than or equal to 10% of the area of the first end face. This better prevents blockage of the drainage channel and avoids a decrease in flow velocity when water passes through it.
[0018] In some embodiments, the drainage channel has at least an arc-shaped section. This reduces the collision between the water flow and the channel wall as the water flows through it, thereby minimizing energy loss.
[0019] In some embodiments, the drainage channel includes a first section and a second section connected to the first section. The second section is located on the side of the first section away from the inlet. The first section is constructed as a straight section, and the second section is constructed as an arc-shaped section. In some cases, the size of the filter device in the horizontal direction (corresponding to the case where the bottom wall of the first housing faces downward) is large. In this case, the horizontal distance between the inlet and the recess is relatively large. Therefore, the drainage channel can be constructed to include the first section and the second section connected to each other, wherein the first section is a straight section and the second section is an arc-shaped section. This makes the shape of the drainage channel more suitable for the case where the horizontal distance between the inlet and the recess is relatively large, and also makes the shape of the drainage channel transition more naturally, thereby helping to reduce the energy loss when the water flows in the drainage channel.
[0020] In some embodiments, the drainage channel is detachably connected to the first housing. This facilitates maintenance or replacement of the drainage channel.
[0021] In some embodiments, a water-passing gap is provided between the second end of the drainage channel and the inner cavity of the housing. This water-passing gap allows the drainage channel to communicate with the inner cavity of the housing, so that when the pool cleaning robot performs cleaning tasks, external water can enter the inner cavity of the housing through the drainage channel, be filtered, and then discharged from the outlet. Additionally, since the drainage channel communicates with the inner cavity of the housing, when the pool cleaning robot is connected to a base station and the base station performs waste collection, waste in the inner cavity of the housing can also enter the drainage channel through the water-passing gap and be further sucked away by the base station's suction pump.
[0022] In some embodiments, the filtration device further includes a guide member located inside the housing and disposed on the side of the flow channel near the second housing. By providing the guide member between the flow channel and the second housing, the guide member can suppress the generation of vortices, that is, it can prevent the formation of vortices at the first end of the flow channel, thereby improving the efficiency of water flow in and out of the filtration device and thus helping to reduce dirt residue in the filtration device.
[0023] In some embodiments, the first end of the guide is close to the side wall, and the second end of the guide is close to the second end of the drainage channel; wherein, when the bottom wall of the housing is facing downwards, the second end of the guide is lower than the first end of the guide. When the bottom wall of the housing is facing downwards, the second end of the guide is lower than the first end of the guide, and in this case, the guide is inclined. When the pool cleaning robot is connected to the base station, the dirt in the inner cavity of the housing will fall to the location of the second end of the drainage channel under the guidance of the guide, thereby reaching the first end face through the water passage gap. In this way, when the base station's suction pump is working, the dirt located at the first end face can easily enter the guide channel and be further sucked away by the suction pump. As a result, the dirt residue in the filter device can be further reduced.
[0024] In some embodiments, the guide member is detachably connected to the drainage channel. This facilitates maintenance or replacement of the guide member. Furthermore, during the assembly of the filter device, the guide member and drainage channel can be assembled into a single component first, and then this component can be connected to the first housing. This makes the assembly process easier and improves assembly efficiency.
[0025] In some embodiments, a movable plate is provided at the second end of the drainage channel. The movable plate is movably connected to the channel wall of the drainage channel, and the flow area of the water passage gap can be changed by changing the angle of the movable plate. With the movable plate at the second end of the drainage channel, when the pool cleaning robot is performing a cleaning task, the movable plate can rotate relative to the channel wall of the drainage channel, thereby increasing the flow area of the water passage gap and improving the cleaning efficiency of the pool cleaning robot.
[0026] In some embodiments, the filtration device further includes a filter assembly disposed in the second housing. During the cleaning task performed by the pool cleaning robot, as water flows from the inlet into the inner cavity of the housing and then out through the outlet, the filter assembly can filter the water flow, and the filtered dirt will remain in the inner cavity.
[0027] In some embodiments, the filter device further includes a handle, which is fixedly connected to the first housing. By gripping the handle, the filter device can be easily lifted and moved, thus making it easier to remove the filter device from the body of the pool cleaning robot or to install the filter device on the body of the pool cleaning robot.
[0028] An embodiment of the second aspect of this application provides a pool cleaning robot system, the pool cleaning robot system including a pool cleaning robot, the pool cleaning robot including the filtration device in any of the above embodiments.
[0029] The pool cleaning robot system in this application embodiment is based on the same inventive concept as the filtration device in the above embodiment. Therefore, the pool cleaning robot system can obtain the beneficial effects of the filtration device in the corresponding embodiment.
[0030] In some embodiments, the pool cleaning robot system further includes a base station with a docking interface. The filtration device also includes a drainage channel connected to the first housing and communicating with the inner cavity of the housing. A water inlet is provided on the side wall of the first housing. When the pool cleaning robot is connected to the base station, a portion of the docking interface communicates with the drainage channel through the water inlet. The base station is also equipped with a suction pump for pumping out dirt from the filtration device through the docking interface. By providing a base station with a suction pump and a docking interface, dirt in the filtration device can be recycled. After recycling the dirt from the filtration device, the pool cleaning robot can return to the pool to perform cleaning tasks. Compared to the traditional method of manually cleaning the filtration device of a pool cleaning robot, this significantly reduces the burden on humans.
[0031] In some embodiments, when the pool cleaning robot is connected to the base station, dirt in the filter device accumulates at the converging extension end of the first housing. When the base station's suction pump operates, the accumulated dirt can be easily sucked away by the pump's suction action. This facilitates more thorough recovery of dirt from the filter device and reduces dirt residue in the filter device. Attached Figure Description

[0051] like Figures 1 to 6 As shown, an embodiment of the first aspect of this application provides a filtering device 10, which includes a housing 100. The housing 100 includes a first housing 110 and a second housing 120 connected to the first housing 110. The first housing 110 has a receiving space, and the second housing 120 covers the opening of the receiving space. The first housing 110 converges (i.e., gradually narrows) from one end near the second housing 120 to one end away from the second housing 120.
[0052] The filter device 10 in this embodiment is used for a pool cleaning robot 1. When the pool cleaning robot 1 operates in a pool, the filter device 10 can collect dirt (mainly solid waste) in the water. It is understood that the orientation of the filter device 10 will change depending on the orientation of the pool cleaning robot 1. Specifically, when the pool cleaning robot 1 operates at the bottom of the pool, the side wall 111 of the first housing 110 of the filter device 10 faces downwards (see reference). Figure 2 As shown), the first housing 110 has a water inlet on its side wall 111, and the second housing 120 has a water outlet 102. When the pool cleaning robot 1 is working at the bottom of the pool, the water inlet 101 on the side wall 111 also faces downwards. When the pool cleaning robot 1 climbs up the pool wall, the bottom wall 112 of the first housing 110 faces downwards (see reference). Figure 5 As shown), at this time, the water inlet 101 faces horizontally. When the pool cleaning robot 1 is connected to the base station, the bottom wall 112 of the first housing 110 faces downwards (see reference). Figure 5 (As shown), and the inlet 101 faces horizontally. That is to say, in the latter two cases, the orientation of the filter device 10 is the same.
[0053] When the pool cleaning robot 1 performs a cleaning task, water flows into the inner cavity of the housing 100 through the inlet 101 and then out through the outlet 102. Typically, the filter device 10 also contains a filter assembly, which filters out dirt carried by the water and retains it in the inner cavity of the housing 100.
[0054] In this embodiment of the application, when the pool cleaning robot 1 is connected to the base station, the bottom wall 112 of the first housing 110 of the filter device 10 faces downwards. Since the first housing 110 converges from the end near the second housing 120 to the end away from the second housing 120, dirt accumulates in the narrower area formed after the convergence. When the base station's suction pump operates, the accumulated dirt can be easily sucked away by the pump's suction action. This facilitates more thorough dirt recovery in the filter device 10, reducing dirt residue in the filter device 10.
[0055] like Figure 2 , Figure 5 As shown, in some embodiments, the first housing 110 converges and extends, forming a first end face at the end of the first housing 110 away from the opening, the area of the first end face being smaller than the area of the opening of the accommodating space. Thus, when the pool cleaning robot 1 is connected to the base station, dirt will accumulate at the first end face, making it more concentrated and easier to suck away.
[0056] like Figure 2 , Figure 5 As shown, in some embodiments, the first end face is positioned approximately opposite to the center of the second housing 120. For example, the first end face is directly opposite the center of the second housing 120, or slightly offset from the center of the second housing 120. This arrangement ensures that the first end face is approximately opposite to the center of the opening of the first housing 110. When the pool cleaning robot 1 is connected to the base station, this facilitates the accumulation of dirt from various locations within the containment space towards the first end face under the influence of gravity.
[0057] like Figure 5 As shown, in some embodiments, the first housing 110 includes a sidewall 111 and a bottom wall 112 connected to the sidewall 111. The sidewall 111 is disposed adjacent to the second housing 120, and the bottom wall 112 is disposed opposite to the second housing 120. The sidewall 111 is provided with a water inlet 101. The bottom wall 112 has a recess 1121 recessed in a direction away from the second housing 120, and a first end face is formed in the recess 1121. By providing the recess 1121 on the bottom wall 112, it is relatively easy to construct a shape in which the first housing 110 converges and extends from the end near the second housing 120 to the end away from the second housing 120, thereby satisfying the requirement of allowing dirt to collect on the first end face.
[0058] like Figure 2 , Figure 5As shown, in some embodiments, the bottom wall 112 includes a first wall panel 1122 and a second wall panel 1123. Multiple first wall panels 1122 are arranged around the second wall panel 1123. The second wall panel 1123 is connected to the multiple first wall panels 1122, and the side of the second wall panel 1123 facing the opening forms a first end face. The included angle between the first wall panel 1122 and the second wall panel 1123 is greater than 90° and less than 180°.
[0059] With this configuration, the first wall panel 1122 and the second wall panel 1123 can be used to create a recess 1121 on the bottom wall 112 of the first housing 110 that is recessed in a direction away from the second housing 120, thereby achieving the effect of allowing dirt to accumulate in the recess 1121 of the bottom wall 112.
[0060] In one embodiment, the included angle between the first wall panel 1122 and the second wall panel 1123 is greater than or equal to 120° and less than or equal to 160°.
[0061] If the angle is too large, the recess 1121 will be less noticeable, making it difficult for dirt to accumulate there. Conversely, if the angle is too small, the first housing 110 will be too large in the direction of the recess, resulting in an excessively large filter device 10. Therefore, the angle is limited to a range of 120° to 160°. Extensive testing has shown that under these conditions, dirt accumulates well in the recess 1121 without the filter device 10 becoming too large.
[0062] like Figure 2 , Figure 5 As shown, in some embodiments, the filter device 10 further includes a drainage channel 200, which is connected to the first housing 110 and communicates with the inner cavity of the housing 100. The first housing 110 includes a side wall 111 and a bottom wall 112 connected to the side wall 111. The side wall is provided with a water inlet 101. The first end 201 of the drainage channel 200 is located at the water inlet 101, and the second end 202 of the drainage channel 200 extends to be approximately opposite to the converging extension end of the first housing 110.
[0063] When the pool cleaning robot 1 performs its cleaning task, water flows into the inner cavity of the housing 100 through the inlet 101 and the drainage channel 200, and then exits through the outlet 102. During this process, the water flows through the filter components of the filter device 10, thereby filtering the water in the pool.
[0064] When the pool cleaning robot 1 is connected to the base station, the interface on the base station can extend into the guide channel 200 through the water inlet 101. Since the second end 202 of the guide channel 200 extends to be approximately opposite to the converging extension end of the first housing 110, when the base station's suction pump is working, the dirt accumulated at the converging extension end of the first housing 110 can be more easily sucked away through the guide channel 200 under the suction action of the suction pump. This helps to make the dirt in the filter device 10 more thoroughly recovered, thereby further reducing the dirt residue in the filter device 10.
[0065] In one embodiment, the first housing 110 converges and extends to form a first end face at the end of the first housing 110 away from the opening, the area of the first end face being smaller than the area of the opening. The second end 202 of the drainage channel 200 extends toward the first end face and is opposite to the first end face.
[0066] With this configuration, when the pool cleaning robot 1 is connected to the base station, dirt will accumulate at the first end face, and the second end 202 of the drainage channel 200 extends towards and faces the first end face. This allows the dirt at the first end face to be more easily sucked away through the drainage channel 200, thereby facilitating more thorough recovery of dirt in the filter device 10.
[0067] In one embodiment, the difference between the opening area of the second end 202 of the drainage channel 200 and the area of the first end face is less than or equal to 20% of the area of the first end face. This arrangement ensures that the opening area of the second end 202 of the drainage channel 200 is approximately equal to the area of the first end face. This avoids both situations where the opening area of the drainage channel 200 is too small, making it prone to blockage, and where the opening area is too large, resulting in a low flow velocity and thus affecting the efficiency of waste recovery.
[0068] Preferably, the difference between the opening area of the second end 202 of the drainage channel 200 and the area of the first end face is less than or equal to 10% of the area of the first end face. This can better prevent the drainage channel 200 from becoming blocked and avoid the problem of reduced flow velocity when water flows through the drainage channel 200.
[0069] like Figure 2 , Figure 5 As shown, in some embodiments, the drainage channel 200 has at least an arc-shaped section. Therefore, when water flows in the drainage channel, it helps to reduce the collision between the water flow and the channel wall, thereby reducing the energy loss of the water flow.
[0070] like Figure 2 , Figure 5As shown, in one embodiment, the drainage channel 200 includes a first section 210 and a second section 220 connected to the first section 210. The second section 220 is located on the side of the first section 210 away from the inlet 101. The first section 210 is constructed as a straight section, and the second section 220 is constructed as an arc-shaped section.
[0071] In some cases, the size of the filter device 10 in the horizontal direction (corresponding to the case where the bottom wall 112 of the first housing 110 faces downward) is relatively large. In this case, the horizontal distance between the inlet 101 and the recess 1121 is relatively large. Therefore, the guide channel can be constructed to include a first section 210 and a second section 220 that are connected to each other. The first section 210 is a straight section and the second section 220 is an arc-shaped section. This makes the guide channel more suitable in shape for the case where the horizontal distance between the inlet 101 and the recess 1121 is relatively large, and also makes the transition of the guide channel in shape more natural, thereby helping to reduce the energy loss when the water flows in the guide channel 200.
[0072] In some embodiments, the drainage channel 200 is detachably connected to the first housing 110. This facilitates maintenance or replacement of the drainage channel 200.
[0073] like Figure 2 , Figure 5 As shown, in some embodiments, a water passage gap 103 is provided between the second end 202 of the drainage channel 200 and the inner cavity of the housing 100. This water passage gap 103 allows the drainage channel to communicate with the inner cavity of the housing 100. Thus, when the pool cleaning robot 1 performs a cleaning task, external water can enter the inner cavity of the housing 100 through the drainage channel, be filtered, and then discharged from the outlet 102. Furthermore, since the drainage channel communicates with the inner cavity of the housing 100, when the pool cleaning robot 1 is connected to a base station and the base station performs waste collection, waste in the inner cavity of the housing 100 can also enter the drainage channel through the water passage gap 103 and be further sucked away by the base station's suction pump.
[0074] like Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, in one embodiment, the filter device 10 further includes a guide 300 located inside the housing 100 and disposed on the side of the drainage channel 200 near the second housing 120.
[0075] When the suction pump is working, external water enters the filter device 10 through the outlet 102, passes through the diversion channel 200, and is discharged through the inlet 101. During this process, the water carries away dirt along with it. The connection between the diversion channel 200 and the side wall 111 forms a relatively obvious corner structure, making it prone to vortex formation. The generation of vortices can make it difficult to completely remove dirt. In this embodiment, by providing a guide 300 between the diversion channel 200 and the second housing 120, the guide 300 can suppress the generation of vortices. That is, it can prevent the formation of vortices at the first end 201 of the diversion channel 200, thereby improving the efficiency of water flow in and out of the filter device 10, and thus helping to reduce dirt residue in the filter device 10.
[0076] In one embodiment, the first end 301 of the guide 300 is near the sidewall 111 of the first housing 110, and the second end 202 is near the drainage channel 200. When the bottom wall 112 of the housing 100 is facing downwards, the second end 302 of the guide 300 is lower than the first end 301 of the guide 300 (see reference). Figure 5 ).
[0077] When the bottom wall 112 of the housing 100 is facing downwards, the second end 302 of the guide member 300 is lower than the first end 301 of the guide member 300, and the guide member 300 is inclined. When the pool cleaning robot 1 is connected to the base station, the dirt in the inner cavity of the housing 100 will fall to the location of the second end 202 of the drainage channel 200 under the guidance of the guide member 300, and then reach the first end face through the water passage gap 103. In this way, when the base station's sewage pump is working, the dirt located at the first end face can easily enter the guide channel and be further sucked away by the sewage pump. As a result, the amount of dirt residue in the filter device 10 can be further reduced.
[0078] In one embodiment, the guide 300 is constructed as a flat plate structure, which makes the guide 300 easy to process and helps to shorten the processing time.
[0079] like Figure 2 , Figure 5 As shown, in another embodiment, the guide member 300 has at least an arc-shaped plate segment 310. The arc-shaped plate segment 310 has a good guiding effect on the water flow. Thus, as the water flows through the guide member 300, it helps to suppress the formation of vortices. The generation of vortices will reduce the filtration efficiency of the filter device 10. Therefore, when the guide member 300 has at least an arc-shaped plate segment 310, it is beneficial to improve the filtration efficiency of the filter device 10.
[0080] In one embodiment, the guide 300 is detachably connected to the drainage channel 200. This facilitates maintenance or replacement of the guide 300. Furthermore, during assembly of the filter device 10, the guide 300 and the drainage channel 200 can be assembled into a single component before connecting this component to the first housing 110. This simplifies the assembly process and improves assembly efficiency.
[0081] like Figure 2 , Figure 5 As shown, in one embodiment, the second end 202 of the drainage channel 200 is provided with a movable plate 230, which is movably connected to the channel wall of the drainage channel 200. The flow area of the water passage gap 103 can be changed by changing the angle of the movable plate 230.
[0082] The second end 202 of the drainage channel 200 is provided with a movable plate 230. When the pool cleaning robot 1 is performing a cleaning task, the movable plate 230 can be rotated relative to the channel wall of the drainage channel 200, thereby increasing the flow area of the water passage gap 103. This can improve the cleaning efficiency of the pool cleaning robot 1.
[0083] Understandably, please combine Figure 6 The pool cleaning robot 1 has a built-in water flow drive component 20 (e.g., a water pump). Driven by the water flow drive component 20, external water enters the filter device 10 for filtration. Therefore, the movable plate 230 can be hinged to the channel wall of the guide channel 200. In this way, as the water flows from the guide channel into the inner cavity of the housing 100, the water flow can drive the movable plate 230 to rotate, thereby increasing the flow area of the water passage gap 103.
[0084] Alternatively, a motor can be set up to drive the movable plate 230 to rotate. When the pool cleaning robot 1 is performing a cleaning task, the movable plate 230 can be controlled to rotate by the motor, thereby increasing the flow area of the water passage gap 103.
[0085] In some embodiments, the filtering device 10 further includes a filtering assembly (not shown) disposed in the second housing 120. Exemplarily, the filtering assembly may include at least one of a porous material and a filter screen, wherein the porous material is, for example, a sponge.
[0086] During the cleaning process of the pool cleaning robot 1, as water flows from the inlet 101 into the inner cavity of the housing 100 and then out through the outlet 102, the filter assembly can filter the water flow, and the filtered dirt will remain in the inner cavity.
[0087] like Figure 2 , Figure 3As shown, in some embodiments, the filter device 10 further includes a handle 400, which is fixedly connected to the first housing 110. By holding the handle 400, it is easy to lift and move the filter device 10, thus making it easier to remove the filter device 10 from the body 30 of the pool cleaning robot 1 or to install the filter device 10 on the body 30 of the pool cleaning robot 1.
[0088] An embodiment of the second aspect of this application provides a pool cleaning robot system, such as Figure 6 As shown, the pool cleaning robot system includes a pool cleaning robot 1, which includes the filtration device 10 in any of the above embodiments.
[0089] The pool cleaning robot system in this application embodiment is based on the same inventive concept as the filtration device 10 in the above embodiment. Therefore, the pool cleaning robot system can obtain the beneficial effects of the filtration device 10 in the corresponding embodiment.
[0090] In some embodiments, the pool cleaning robot system further includes a base station (not shown), which has a docking interface. The filter device 10 also includes a drainage channel 200, which is connected to the first housing 110 and communicates with the inner cavity of the housing 100. The side wall of the first housing 110 is provided with a water inlet 101. When the pool cleaning robot 1 is connected to the base station, the docking interface is connected to the drainage channel 200 through the water inlet 101. The base station is also provided with a suction pump, which is used to suck up dirt from the filter device 10 through the docking interface.
[0091] The inlet of the vacuum pump can be directly connected to the docking port, or a suction pipe can be installed between the inlet of the vacuum pump and the docking port. In this way, when the vacuum pump is working, it can suck up the dirt in the filter device 10 through the docking port.
[0092] By setting up a base station equipped with a suction pump and a connection interface, the waste in the filter device 10 can be recycled. After the waste in the filter device 10 has been recycled, the pool cleaning robot 1 can return to the pool to perform cleaning tasks. Compared with the traditional method of manually cleaning the filter device 10 of the pool cleaning robot 1, this significantly reduces the burden on humans.
[0093] In some embodiments, when the pool cleaning robot 1 is connected to the base station, dirt in the filter device 10 accumulates at the converging extension end of the first housing. When the base station's suction pump operates, the accumulated dirt can be easily sucked away by the pump's suction action. This facilitates more thorough recovery of dirt from the filter device 10 and reduces dirt residue in the filter device 10.
[0094] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
