Description

Technical Field

[0001] This utility model relates to the field of intelligent cleaning equipment technology, especially swimming pool cleaning technology, and more specifically, to a dual-channel swimming pool robot. Background Technology

[0002] Pool cleaning robots are becoming increasingly important as a professional cleaning device. These robots are specifically designed for cleaning private or public pools, significantly reducing labor costs and providing a more thorough and efficient cleaning experience compared to traditional manual cleaning methods.

[0003] In existing pool robots, there is usually a suction port at the front or bottom, and a roller brush is installed at the front end corresponding to the suction port. The function of the roller brush is to scrape up the garbage at the bottom of the pool and suck it into the pool robot. Then, the coarse particles are collected by the filter screen in the garbage collection device, thus achieving the cleaning of the pool.

[0004] However, if the mesh size of the filter in the garbage collection device is set too large, it will be difficult to collect small pieces of trash; but if the mesh size is set too small, some cotton-like suspended matter in the pool can easily clog the filter. When the filter is blocked by leaves or clogged by cotton-like suspended matter, the water flow at the outlet will become very small.

[0005] When a pool robot is climbing walls or cleaning the pool sidewalls, it relies on the water sprayed from its outlet to maintain pressure and adhere tightly to the pool wall. If the filter becomes clogged, the water pressure at the outlet decreases, increasing the risk of the robot tilting backward or falling. This can lead to incomplete cleaning and, in severe cases, damage to the robot.

[0006] Some manufacturers, to prevent the pool robot from tilting back or falling while climbing walls or cleaning pool sides, install pressure sensors in the waste collection device or water flow sensors at the outlet. By detecting the pressure inside the waste collection device or collecting data on reduced water flow at the outlet, they control the pool robot to prevent it from climbing walls or cleaning the sides. However, users cannot predict when or to what extent the filter will become clogged. When climbing walls or cleaning the sides is needed, the limitations imposed by sensor data degrade the user experience and increase the manufacturing cost of the pool robot due to the addition of various sensors.

[0007] Therefore, how to ensure that pool robots do not risk tilting their heads back or falling when climbing walls or cleaning pool sidewalls is a technical problem that the industry urgently needs to solve. Utility Model Content

[0008] The present invention aims to overcome the shortcomings of the prior art and provide a dual-channel pool robot to solve the problems of tilting its head back or falling when the existing pool robot is climbing or cleaning the side walls.

[0009] The technical solution adopted by this utility model is to provide a dual-channel swimming pool robot, including a swimming pool robot body, the swimming pool robot body being provided with an inner cavity, and a walking mechanism being provided at the lower part or side of the swimming pool robot body.

[0010] A waste collection device is provided in the inner cavity of the main body. The lower part of the waste collection device is provided with a waste collection port, and the side and / or top of the waste collection device are provided with a filter screen.

[0011] A drain outlet is provided on the top and / or side of the body, and the drain outlet is in communication with the inner cavity.

[0012] The drain outlet can be located on both the top and side of the main body. The top drain outlet allows the pool robot to better conform to the wall when climbing due to the reaction force of the water. The side drain outlet provides thrust during drainage, enabling the pool robot to move to the other side and perform lateral cleaning of the water surface.

[0013] The first water inlet is connected to the garbage collection port and is located at the lower part, front part, or side part of the main body.

[0014] The first water inlet is located at the bottom front. The first water inlet is used for daily waste suction. When water enters through the first water inlet, the debris mixed in the water stays in the waste collection device, and the clean water is discharged from the drain, thus achieving daily pool cleaning.

[0015] The second water inlet is located at the bottom of the pool robot body and behind the first water inlet in the forward direction. An inner cavity water inlet is provided on the inner cavity sidewall, and the second water inlet is interconnected with the inner cavity through the inner cavity water inlet.

[0016] The water pump is located between the first water inlet and the inner cavity, and the water pump provides power for the water flow during cleaning.

[0017] During operation, water flows in through the second inlet using the suction of the water pump, then flows into the inner cavity through the inner cavity inlet, and finally flows out through the outlet, forming a second flow channel in addition to the normal cleaning channel.

[0018] A roller brush, comprising a roller brush shaft and roller brush blades disposed on the outer periphery of the roller brush shaft, wherein the roller brush is disposed at the front or lower part of the body, and the roller brush is driven to rotate by a drive motor or by the walking mechanism.

[0019] The function of the roller brush is to better collect trash, and at the same time, the roller brush can scrub and clean the bottom, side walls or water level of the pool while rotating.

[0020] In one technical solution, a first valve is provided at the second water inlet, and a second valve is provided at the inner cavity water inlet. The second valve is fixed to the inner cavity side wall of the main body. When the second water inlet and the inner cavity are interconnected, the water flow channel is opened or closed by the first valve and / or the second valve.

[0021] In one technical solution, a transverse pivot is provided on the inner wall of the body above the water inlet of the inner cavity, and the second valve is fixed on the pivot, so that the second valve rotates around the pivot.

[0022] You can also set it to a hinge-like configuration, which will achieve the same effect.

[0023] In one technical solution, the second valve has a plate-like structure. The flat plate-like structure has good edge fit, which makes the valve more effective when closing the water flow channel.

[0024] In one technical solution, the first valve includes a fixed column, a connecting plate, and a valve plate. The valve plate is rotatably fixed at the second water inlet. The fixed column is fixed to the inner bottom of the body. One end of the connecting plate is connected to the valve plate via a first rotating shaft, and the other end is connected to the end of the fixed column via a second rotating shaft. A counterweight is also provided at the end of the connecting plate. The counterweight is positioned close to the second rotating shaft and extends outward.

[0025] In one technical solution, a rotating rod is further provided between the first valve and the second valve, and the two ends of the rotating rod are respectively connected to the first valve and the second valve and rotate relative to each other.

[0026] In one technical solution, the first valve includes a fixed column, a connecting plate, and a valve plate. The valve plate is rotatably fixed at the second water inlet. The fixed column is fixed to the inner bottom of the body. The connecting plate is connected to the end of the fixed column via a second rotating shaft, and the connecting plate can rotate at the end of the fixed column via the second rotating shaft. A counterweight is also provided at the end of the connecting plate. When the counterweight is set, it is close to the second rotating shaft and extends outward.

[0027] In one technical solution, the connecting plate includes a first connecting plate and a second connecting plate, and a connecting cross plate is further provided between the first connecting plate and the second connecting plate.

[0028] In one technical solution, the counterweight is circular or hemispherical, and a metal counterweight component is embedded within the counterweight.

[0029] In one technical solution, reinforcing ribs are also provided on both sides of the fixing column.

[0030] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0031] This utility model provides a dual-channel pool robot. By adding a second channel, which does not need to pass through a garbage collection device, the water flow through the second channel is stronger. This ensures the posture of the pool robot when climbing walls or cleaning the side walls of the pool, preventing risks such as tilting its head back or falling, and increasing the stability of the pool robot.

[0032] At the same time, it is not necessary to use various flow or pressure detection methods. The detection device is also prone to failure or malfunction. Furthermore, the data detected by the detection device only restricts its installation on the wall or limits the cleaning of the side wall, and cannot completely solve the problem.

[0058] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0059] Example 1

[0060] like Figures 1-11 As shown, this embodiment provides a dual-channel swimming pool robot, including a swimming pool robot body 100. The swimming pool robot body 100 is provided with an inner cavity 101. A walking mechanism 102 is provided on the lower part or side of the swimming pool robot body 100. The walking mechanism 102 can be a walking wheel or a walking track. The walking mechanism 102 mentioned in this embodiment is the same as the walking mechanism 102 used in ordinary swimming pool robots and is a technical solution disclosed in the art. Therefore, the specific structure and function of the walking mechanism 102 will not be described in detail in this embodiment.

[0061] The waste collection device 103 is detachably installed in the inner cavity 101 of the main body 100. A waste collection port is provided at the lower part of the waste collection device 103, and filter screens are provided on the sides and / or top of the waste collection device 103. In this embodiment, filter screens are provided on both the sides and top, which increases the filtration area for better waste collection. Furthermore, the large filter area allows for more water drainage, extending the time the machine is less prone to clogging. The detachable design of the waste collection device 103 allows for easy removal and insertion, facilitating daily cleaning and maintenance. The filter screens on the waste collection device 103 collect waste, enabling daily cleaning of the pool robot.

[0062] A drain outlet 104 is provided on the top and / or side of the body 100, and the drain outlet 104 is in communication with the inner cavity 101.

[0063] In this embodiment, drain outlets 104 are simultaneously located on the top and side of the main body 100. The top drain outlet 104 allows the pool robot to better conform to the wall due to the reaction force of the water when climbing. The side drain outlet 104, with its thrust during drainage, allows the pool robot to move to the other side, enabling lateral cleaning of the water surface.

[0064] It also includes a first water inlet 105, which is connected to the garbage collection port. The first water inlet 105 is located at the lower, front, or side of the main body 100. In this embodiment, the first water inlet 105 is located at the bottom front. The first water inlet 105 is used for daily sludge suction. When water enters through the first water inlet 105, the garbage mixed in the water stays in the garbage collection device 103, and the clean water is discharged from the drain outlet 104, thus achieving daily pool cleaning.

[0065] In this embodiment, a water pump 107 and a power supply device (not shown in the figure) that provides power to the water pump 107 are also included. The power supply device is a storage battery. Other components include control circuits during normal use. Since the power supply and control circuits are common and publicly available structures in swimming pool robots, and no improvements are made to them in this solution, this embodiment will not elaborate on these parts.

[0066] A water pump 107 is disposed between the first water inlet 105 and the inner cavity 101, and the water pump 107 provides power for the water flow during cleaning. The water pump 107 mentioned in this embodiment, as well as its installation position and structure, are consistent with the structure, function, and effect of water pumps in everyday swimming pool robots, and are technical solutions disclosed in this field. Therefore, the specific structure and function of the water pump 107 will not be described in detail in this embodiment.

[0067] The second water inlet 106 is located at the bottom of the pool robot body 100, behind the first water inlet 105 in the forward direction. An inner cavity water inlet 108 is provided on the inner cavity sidewall 109. The second water inlet 106 communicates with the inner cavity 101 through the inner cavity water inlet 108. During operation, water flows in from the second water inlet 106, then into the inner cavity 101 through the inner cavity water inlet 108, and finally flows out from the outlet, forming a second flow channel in addition to normal cleaning.

[0068] In this embodiment, the water pump 107 also provides water flow to the second water inlet 106. It can share a water pump 107 with the first water inlet 105, or it can be driven by a separate water pump 107.

[0069] In this embodiment, a water pump 107 is shared with the first water inlet 105. The use of water pump 107 to draw water in the pool robot is a very mature technical solution, so it will not be described in detail here.

[0070] The roller brush 110 includes a roller brush shaft and roller brush plates disposed on the outer periphery of the roller brush shaft. The roller brush 110 is disposed at the front or lower part of the body 100. The roller brush 110 is driven to rotate by a roller brush motor or by the walking mechanism 102.

[0071] The function of the roller brush 110 is to better collect trash, and at the same time, the roller brush can scrub and clean the bottom, side walls or water level of the pool while rotating.

[0072] like Figures 4-11 As shown, a first valve 200 is provided at the second water inlet 106, and a second valve 300 is provided at the inner cavity water inlet 108. The second valve 300 is fixed to the inner cavity side wall 109 of the body 100. When the second water inlet 106 is connected to the inner cavity 101, the water flow channel is opened or closed through the first valve 200 and / or the second valve 300. Because the water flow does not pass through the waste collection device 103, even if the waste collection device 103 is blocked during operation, the water flow channel can still ensure the normal water spray volume at the outlet, thereby ensuring the normal posture of the pool robot in situations such as climbing walls.

[0073] A transverse pivot 301 is provided on the inner cavity sidewall 109 of the main body 100 above the inner cavity water inlet 108. The second valve 300 is fixed to the pivot 301, causing the second valve 300 to rotate around the pivot 301. In this embodiment, when the pool robot is in a horizontal state, the second valve 300 rotates up and down around the pivot 301, thereby opening or closing the inner cavity water inlet 108.

[0074] like Figure 3 , Figure 4 As shown, when the pool robot is in normal horizontal motion, the inner cavity sidewall 109 is vertical or slightly inclined. Therefore, the pivot 301 is positioned above the second valve 300, so that the second valve 300 is vertically or relatively vertically attached to the inner cavity sidewall 109 in normal operation. It mainly relies on its own downward gravity, without the need for additional external forces.

[0075] In one embodiment, the second valve 300 has a plate-like structure. The flat plate-like structure has good edge fit, which makes the valve more effective when closing the water flow channel. The plate-like valve can also have a slope on the non-closed surface, so that its cross-section is roughly trapezoidal. This can reduce the weight of some areas and make it easier to open automatically when water needs to pass through.

[0076] like Figures 9-11 As shown, in one embodiment, the first valve 200 includes a fixing column 201, a connecting plate 202, and a valve plate 203. The valve plate 203 is rotatably fixed at the second water inlet 106. The fixing column 201 is fixed on the inner bottom of the body 100. One end of the connecting plate 202 is connected to the valve plate 203 through a first rotating shaft 204, and the other end is connected to the end of the fixing column 201 through a second rotating shaft 205. A counterweight 206 is also provided at the end of the connecting plate 202. The counterweight 206 is positioned close to the second rotating shaft 205 and extends outward.

[0077] In this embodiment, the counterweight 206 and the connecting plate 202 are integrally formed, or they can be fixed with screws. Other methods of connection do not affect the performance of the counterweight. Therefore, they will not be described in detail in this embodiment.

[0078] In one embodiment, a rotating rod 207 is further provided between the connecting plate 202 and the valve plate 203. Both ends of the rotating rod 207 are connected to the connecting plate 202 and the valve plate 203 respectively and rotate relative to each other. During connection, a limit block is provided on the upper side of the connection between the connecting plate 202 and the rotating rod 207. The limit block extends towards the rotating rod 207, and when the rotating rod 207 rotates to the limit block, the rotating rod 207 and the connecting plate 202 form an inclined straight line, thus preventing excessive rotation.

[0079] In practice, when the pool robot is working at the bottom of the pool, it walks horizontally. At this time, the counterweight 206 is completely positioned above the valve plate 203, and the connecting plate 202 and the rotating rod 207 form an inclined straight line, thereby ensuring that the valve plate 203 is in close contact with the second water inlet 106. This achieves the closed state of the second water inlet 106.

[0080] like Figure 6 As shown, when the pool robot is in the wall-climbing or stair-climbing state, the pool robot is in a vertical or tilted state. At this time, the counterweight 206 is tilted up by gravity, which drives the rotating rod 207 to lift up. The valve fixed at the end of the rotating rod 207 is also driven to move upward, thereby opening the valve plate 203.

[0081] The principle of opening and closing the valve plate 203 in this solution is to use the counterweight block 206 to rotate according to different scenarios, thereby driving the second water inlet 106 to open or close.

[0082] In one embodiment, when two connecting plates 202 are provided simultaneously, they include a first connecting plate and a second connecting plate, and a connecting cross plate 210 is also provided between the first connecting plate and the second connecting plate. The function of the connecting cross plate 210 is to connect and fix the first connecting plate and the second connecting plate, so that the first connecting plate, the second connecting plate, and the connecting cross plate 210 are fixed together as a whole, and are roughly in the shape of "I".

[0083] The first connecting plate, the second connecting plate, and the connecting cross plate 210 are connected to each other to form a fixed whole, which enhances their stability. This ensures that the force and angle used when opening the valve are consistent, preventing uneven openings and ensuring a uniform water flow rate.

[0084] In one embodiment, the counterweight 206 is circular or hemispherical, and a metal counterweight is embedded within it. In this embodiment, a metal counterweight is preferred because it provides better weight for the same volume. However, other variations of this solution, such as filling the counterweight 206 with sand or rubber, can also achieve the same effect.

[0085] In one embodiment, reinforcing ribs 209 are also provided on both sides of the fixing column 201.

[0086] Because the fixed column 201 supports the connecting plate 202 and frequently switches between open and closed states during operation, it experiences significant stress. If the fixed column 201 is too large, it wastes space; if it is too small, frequent use will cause structural fatigue and breakage. Therefore, by providing reinforcing ribs 209 on both sides, the fixed column 201 can achieve the strength required for daily use without occupying a large area.

[0087] Example 2

[0088] like Figures 12-22As shown, this embodiment provides a dual-channel swimming pool robot. In this embodiment, the first valve 200 includes a fixed column 201, a connecting plate 202, and a valve plate 203. The valve plate 203 is rotatably fixed to the bottom of the swimming pool robot and corresponds to the second water inlet 106. The fixed column 201 is fixed to the inner bottom of the body 100 and is placed on one side of the second water inlet 106. The connecting plate 202 is connected to the end of the fixed column 201 through a second rotating shaft 205, and the connecting plate 202 can rotate at the end of the fixed column 201 through the second rotating shaft 205.

[0089] One end of the connecting plate 202 away from the fixed column 201 abuts or contacts the valve plate 203. A counterweight 206 is also provided at the other end of the connecting plate 202, with both ends being free ends. When the pool robot is in a horizontal position, the counterweight 206 is positioned near the second rotating shaft 205 and extends upwards towards the water outlet. The extended counterweight 206 allows the connecting plate 202 to rotate freely around the second rotating shaft 205 at different angles, depending on the change in the center of gravity.

[0090] like Figure 12 As shown, in a horizontal state, the valve plate 203 is in close contact with the second water inlet 106, so that the second water inlet 106 is in a closed state; the connecting plate 202 is subjected to the gravity of the counterweight 206, and at the same time, it is in close contact with the valve plate 203. At this time, due to the action of the counterweight 206 on the connecting plate 202, the valve plate 203 is not opened by the impact force of water.

[0091] like Figure 22 As shown, in this embodiment, the counterweight 206 is circular. The distance from the center of the second rotating shaft 205 to the center of the counterweight 206 is L, and the distance from the center of the second rotating shaft 205 to the middle of the end of the connecting plate 202 is L'. In this embodiment, L and L' form a "V" shape, where the angle formed by the "V" shape is an obtuse angle. The obtuse angle allows for a greater distance between them, and as long as the angle is slightly tilted, the force of the two forces makes rotation easy.

[0092] like Figure 15 As shown, when climbing the wall, the pool robot is in an inclined or vertical position. At this time, the counterweight 206 rotates at a certain angle due to the force of the center of gravity, and the end of the connecting plate 202 moves away from the valve plate 203. At this time, the valve plate 203 is opened by the impact force of the water flow, and water enters the pool robot. Since the pool robot is in an inclined or vertical position, the inner cavity sidewall 109 is in a horizontal position. The second valve 300 is not under external force. At this time, affected by the water flow, the valve plate 203 at the second inlet 106 is opened by the water flow, and water enters the inner cavity 101. Then the water flows out from the outlet, forming a second flow channel.

[0093] When climbing the wall, the second water inlet 106 opens, forming a separate water flow channel that does not need to enter the waste collection device 103. Therefore, even if the waste collection device 103 becomes clogged during operation, this water flow channel can still ensure a normal water spray volume from the outlet, thus ensuring the normal posture of the pool robot when climbing the wall.

[0094] In this embodiment, the normal posture of the pool robot refers to the fact that the water outlet of the pool robot is located on the upper part of the robot. When climbing the wall, the water spraying from the outlet makes the pool robot stick tightly to the wall. However, after cleaning, the waste in the trash collection device 103 of a traditional pool robot is affected by the collected trash, which reduces the water flow. When the water flow is reduced, the water volume at the outlet is also reduced. As a result, the pool robot does not have enough recoil force to stick to the wall, causing the pool robot to tilt its head back and fall.

[0095] In this embodiment, there is no fixed connection between the connecting plate 202 and the valve plate 203. In a horizontal state, the connecting plate 202 presses against the valve plate 203 under the pressure of the counterweight 206. When the swimming pool robot is climbing slopes, walls, and steps, its body posture is changed. The counterweight 206 moves freely according to the current state of the swimming pool robot, so that the valve can be easily opened after it is not under the pressure of the counterweight. The second flow channel also opens during the process of climbing slopes, walls, and steps.

[0096] This embodiment presents another variation of the structure and opening method of the first valve. The structure and function of the pool robot are consistent with those of Embodiment 1, and it achieves the same technical effects. Therefore, further details will not be provided in this embodiment.

[0097] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
