Description

Technical Field

[0001] The present invention relates to the technical field of intelligent cleaning equipment, in particular to swimming pool cleaning technology, and more specifically to a dual-channel swimming pool robot. Background Art

[0002] Against the backdrop of current technological innovation and the booming high-end manufacturing industry, pool robots are becoming increasingly important as professional cleaning devices. These robots, specifically designed for cleaning private or public pools, not only significantly save labor costs but also provide a more thorough and efficient cleaning effect than traditional manual cleaning methods.

[0003] In existing swimming pool robots, a sewage suction port is usually provided at the front or bottom thereof, and a roller brush is provided at the front end corresponding to the sewage 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 swimming pool robot. Then, the coarse particles are collected by the filter net in the garbage collection device, thereby achieving the cleaning of the swimming pool.

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

[0005] When a pool robot is climbing a wall or cleaning the side of a pool, it relies on the water sprayed from the water outlet to keep the pool robot in close contact with the pool wall. If the filter is clogged, the water pressure at the outlet will decrease, and the pool robot may be prone to tilting its head back or falling. This can easily lead to incomplete cleaning and even damage the pool robot in serious cases.

[0006] To prevent tilting back or falling while climbing walls or cleaning pool sides, some manufacturers install pressure sensors in the waste collection unit or flow sensors at the water outlet. By detecting pressure within the waste collection unit or collecting data indicating reduced water flow at the water outlet, these pool robots are prevented from climbing walls or cleaning side walls. However, users cannot predict when the filter will become clogged or how severe the clog will be. When climbing walls or cleaning side walls is necessary, the robot is limited by sensor data, which reduces the user experience. Furthermore, the addition of various sensors increases the manufacturing cost of the pool robot.

[0007] Therefore, how to ensure that the pool robot does not risk looking up or falling when climbing walls or cleaning the side walls of the pool is a technical problem that the industry urgently needs to solve. Summary of the Invention

[0008] The present invention aims to overcome the deficiencies in the prior art and provide a dual-channel swimming pool robot for solving problems such as tilting the head back or falling when the existing swimming pool robot climbs the wall or sidewall for cleaning.

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

[0010] A garbage collection device is provided in the inner cavity of the main body, a garbage collection port is provided at the bottom of the garbage collection device, and a filter is provided at the side and / or top of the garbage collection device.

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

[0012] Drains can be located on both the top and side of the main body. The top drain allows the pool robot to better adhere to the wall due to the reaction force of the water when climbing a wall. The side drain creates a thrust force during drainage, allowing the pool robot to move to the other side, enabling horizontal cleaning of the water surface.

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

[0014] The first water inlet is arranged at the front of the bottom. The first water inlet is used for daily sewage suction. When water enters from the first water inlet, garbage mixed in the water stays in the garbage collection device, and clean water is discharged from the drain, thus achieving daily swimming pool cleaning.

[0015] The second water inlet is arranged at the bottom of the swimming pool robot body and is placed behind the first water inlet in the forward direction. An inner cavity water inlet is arranged on the side wall of the inner cavity, and the second water inlet is connected to the inner cavity through the inner cavity water inlet.

[0016] The water pump is arranged 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 from the second water inlet through the suction force of the water pump, flows into the inner cavity through the inner cavity water inlet, and then flows out from the water outlet, forming a second flow channel in addition to normal cleaning.

[0018] A roller brush includes a roller brush shaft and a roller brush sheet arranged on the outer periphery of the roller brush shaft. The roller brush is arranged at the front or lower part of the body. 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 collect garbage better. At the same time, the roller brush can scrape and clean the bottom, side walls or water level of the swimming pool during the rotation process.

[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, and the second valve is fixed on the inner cavity side wall of the body; when the second water inlet and the inner cavity are connected to each other, 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 cavity side wall of the body above the inner cavity water inlet, and the second valve is fixed on the pivot so as to rotate around the pivot.

[0022] It can also be set up in a hinge-like manner to achieve the same effect.

[0023] In one technical solution, the second valve is in a plate-like structure. The flat plate-like structure has better fit at each edge, which can make the valve more effective in 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 on the inner bottom of the body, one end of the connecting plate is connected to the valve plate through a first rotating shaft, and the other end is connected to the end of the fixed column through a second rotating shaft, and a counterweight block is also provided at the end of the connecting plate, and the counterweight block is arranged 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 both ends of the rotating rod are respectively connected to the first valve and the second valve and rotate with 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 on the inner bottom of the main body, the connecting plate is connected to the end of the fixed column through a second rotating shaft, and the connecting plate can be rotated at the end of the fixed column through the second rotating shaft, and a counterweight block is also provided at the end of the connecting plate, and the counterweight block is arranged 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 transverse plate is further provided between the first connecting plate and the second connecting plate.

[0028] In one technical solution, the counterweight block is circular or hemispherical, and a metal counterweight piece is embedded in the counterweight block.

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

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The present invention provides a dual-channel swimming pool robot. By adding a second channel, the second channel does not need to pass through a garbage collection device, so that the water flow through the second channel is stronger, ensuring the posture of the swimming pool robot when climbing a wall or cleaning the side wall of the swimming pool, preventing the risk of tilting its head back, falling, etc., and increasing the stability of the swimming pool robot.

[0032] At the same time, there is no need to use various flow or pressure detections, and the detection device is prone to damage or abnormalities. Moreover, the data detected by the detection device only limits its access to 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 are not to be construed as limiting the present invention. To better illustrate the following embodiments, some components in the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent actual product dimensions. Those skilled in the art will appreciate that some well-known structures and their descriptions may be omitted from the accompanying drawings.

[0059] Example 1

[0060] like Figures 1 to 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. The swimming pool robot body 100 is provided with a walking mechanism 102 at the bottom 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 consistent with the walking mechanism 102 used in common swimming pool robots and is a technical solution disclosed in the art. Therefore, the specific structure and function of the walking mechanism 102 are not detailed in this embodiment.

[0061] The garbage collection device 103 is detachably mounted within the inner cavity 101 of the main body 100. A garbage collection opening is provided at the bottom of the garbage collection device 103, and filters are provided on the sides and / or top of the garbage collection device 103. In this embodiment, filters are provided on both the sides and the top, which increases the filtration area for better garbage collection. Furthermore, a wide range of filters allows for more drainage, extending the time the machine remains unblocked. The detachable design of the garbage collection device 103 allows for easy removal and insertion, facilitating daily cleaning and maintenance. The filters provided on the garbage collection device 103 collect garbage, enabling daily cleaning of the pool robot.

[0062] The drain port 104 is provided on the top and / or side of the body 100 , and the drain port 104 is communicated with the inner cavity 101 .

[0063] In this embodiment, drain ports 104 are provided on both the top and side of the body 100. The top drain port 104 allows the pool robot to better adhere to the wall due to the reaction force of the water when climbing the wall. The side drain port 104, when draining water, can move the pool robot to the other side, thereby achieving horizontal cleaning of the water surface.

[0064] The main body 100 further includes a first water inlet 105, which is interconnected with the garbage collection port and is located at the bottom, front, or side of the main body 100. In this embodiment, the first water inlet 105 is located slightly forward of the bottom. The first water inlet 105 is used for daily sewage suction. When water enters through the first water inlet 105, the garbage contained in the water is retained in the garbage collection port 103, and the clean water is discharged from the drain port 104, thus achieving daily pool cleaning.

[0065] In this embodiment, a water pump 107 and a power supply device (not shown in the figure) for providing power to the water pump 107 are also included. The power supply device is a storage battery. Other components included in normal use include a control circuit, etc. Since the power supply and control circuit are common public structures in swimming pool robots in daily life and are not improved in this solution, this embodiment will not elaborate on this part.

[0066] A water pump 107 is disposed between the first water inlet 105 and the inner cavity 101 to provide power for the water flow during cleaning. The water pump 107, its installation location, and structure described in this embodiment are consistent with the structure, function, and effectiveness of water pumps used in common swimming pool robots and are technical solutions disclosed in the art. Therefore, the specific structure and function of the water pump 107 are not 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 through the second water inlet 106, flows into the inner cavity 101 through the inner cavity water inlet 108, and then flows out through the water outlet, forming a second flow path in addition to normal cleaning.

[0068] In this embodiment, the water pump 107 is also used to provide water flow power for the second water inlet 106 , which can share the same water pump 107 with the first water inlet 105 or can be driven by a separate water pump 107 .

[0069] In this embodiment, a water pump 107 is specifically shared with the first water inlet 105. The use of the water pump 107 to absorb water in the swimming 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 a roller brush sheet arranged on the outer periphery of the roller brush shaft. The roller brush 110 is arranged at the front or lower part of the main body 100. The roller brush 110 is driven by a roller brush motor to rotate the roller brush shaft or by the walking mechanism 102 to rotate the roller brush shaft.

[0071] The function of the roller brush 110 is to better collect garbage. At the same time, the roller brush can scrape and clean the bottom, side walls or water level of the swimming pool during the rotation process.

[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 sidewall 109 of the body 100. When the second water inlet 106 and the inner cavity 101 are connected, the first valve 200 and / or the second valve 300 are used to open or close the water flow channel. Because the water does not flow through the garbage collection device 103, even if the garbage collection device 103 is blocked during operation, the water flow channel can still ensure a normal water flow from the water outlet, thereby ensuring the normal posture of the pool robot when climbing a wall.

[0073] A transverse pivot 301 is disposed on the inner cavity sidewall 109 of the body 100 above the inner cavity water inlet 108. The second valve 300 is secured to the pivot 301, allowing the second valve 300 to rotate about the pivot 301. In this embodiment, when the pool robot is in a horizontal position, the second valve 300 rotates up and down about the pivot 301 to open or close 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 tilted. Therefore, the pivot 301 is located above the second valve 300, so that the second valve 300 is normally vertical or relatively vertically attached to the inner cavity sidewall 109. It mainly relies on its own downward force of gravity, without the need for additional external forces.

[0075] In one embodiment, the second valve 300 is a plate-like structure. The flat plate-like structure provides good conformability at the edges, allowing the valve to more effectively close the water flow path. The plate-like valve can also have a slope on the non-closing surface, resulting in a roughly trapezoidal cross-section. This reduces weight in certain areas and facilitates automatic opening when water needs to flow through.

[0076] like Figures 9-11 As shown, in one 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 second water inlet 106, the fixed column 201 is fixed to 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 fixed column 201 through a second rotating shaft 205, and a counterweight block 206 is further provided at the end of the connecting plate 202, and the counterweight block 206 is arranged 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, and can also be fixed by screws. Other ways of combining the two do not affect the effect of the counterweight when used. Therefore, they will not be described in detail in this embodiment.

[0078] In one embodiment, a rotating rod 207 is further disposed between the connecting plate 202 and the valve plate 203. The ends of the rotating rod 207 are connected to the connecting plate 202 and the valve plate 203, respectively, and are rotatable relative to each other. When connected, a limit block is disposed above the connection between the connecting plate 202 and the rotating rod 207. The limit block extends toward the rotating rod 207. When the rotating rod 207 rotates to the limit block, the rotating rod 207 and the connecting plate 202 form an inclined straight line, thereby preventing excessive rotation.

[0079] In a specific implementation, when the pool robot is operating at the bottom of the pool, it is in a horizontal walking state. At this time, the counterweight 206 is completely placed above the valve plate 203, and the connecting plate 202 and the rotating rod 207 form an inclined straight line, thereby making the valve plate 203 and the second water inlet 106 tightly attached to each other. Thus, the second water inlet 106 is closed.

[0080] like Figure 6 As shown, when the swimming pool robot is in the wall climbing state or the ladder climbing state, the swimming pool robot is in a vertical or tilted state. At this time, the counterweight block 206 is lifted up by gravity, driving the rotating rod 207 to move upward, and the valve fixed at the end of the rotating rod 207 is also driven to move upward, thereby realizing the opening of the valve plate 203.

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

[0082] In one embodiment, when two connecting plates 202 are provided, they include a first connecting plate and a second connecting plate, and a connecting transverse plate 210 is further provided between the first connecting plate and the second connecting plate. The connecting transverse plate 210 is used 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 transverse plate 210 are fixed to each other as a whole and form a roughly "I" shape.

[0083] The first connecting plate, the second connecting plate, and the connecting transverse plate 210 are connected to form a fixed whole, which enhances the stability between them and ensures that the force and angle when opening the valve are consistent, so that the opening of the valve does not vary in height or size when one side is opened, thereby ensuring a uniform water flow rate.

[0084] In one embodiment, the counterweight 206 is circular or hemispherical, and a metal counterweight is embedded within the counterweight 206. In this embodiment, metal counterweights are preferred because they provide superior gravity for a given volume. However, other variations of this solution, such as filling the counterweight 206 with sand or rubber, can also achieve similar results.

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

[0086] Because the fixing column 201 supports the connecting plate 202 and frequently switches between open and closed positions during operation, the fixing column 201 is subjected to significant stress. If the body of the fixing column 201 is too large, it wastes space. If the body of the fixing column 201 is too small, it may fatigue and break during frequent use. Therefore, by providing reinforcing ribs 209 on both sides, the fixing column 201 does not occupy a large area while still meeting the strength requirements for daily use.

[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 fixing 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 fixing 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 fixing column 201 via a second rotating shaft 205, and the connecting plate 202 can rotate at the end of the fixing column 201 via the second rotating shaft 205.

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

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

[0091] like Figure 22 As shown, in this embodiment, the counterweight 206 is circular, and 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" is obtuse. The obtuse angle can increase the distance between the two. As long as the angle is tilted, the force between the two can easily rotate.

[0092] like Figure 15 As shown, when the pool robot is wall-climbing, it is tilted or vertical. 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. The valve plate 203 is then pushed open by the impact of the water flow, allowing water to enter the pool robot. Since the pool robot is tilted or vertical, the inner cavity sidewall 109 is horizontal, and the second valve 300 is free of external force. Under the influence of the water flow, the valve plate 203 at the second water inlet 106 is pushed open by the water flow, allowing water to enter the inner cavity 101 and then flow out of the water outlet, forming a second flow channel.

[0093] In the wall-climbing state, the second water inlet 106 is opened, forming a separate water flow channel, and this water flow channel does not need to enter the garbage collection device 103. Therefore, even if the garbage collection device 103 is blocked during operation, this water flow channel can still ensure the normal water flow from the water outlet, thereby ensuring the normal posture of the swimming pool robot in the wall-climbing state.

[0094] The normal posture of the pool robot mentioned in this embodiment refers to the fact that the water outlet of the pool robot is located on the upper part of the pool robot. When climbing a wall, the water outlet sprays water, allowing the pool robot to cling tightly to the wall. However, after cleaning, the waste collection device 103 of a conventional pool robot is affected by the accumulated waste, causing the water flow to decrease. This decreases the water volume at the outlet, which in turn reduces the recoil force of the water, preventing the pool robot from clinging to the wall. This can cause 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 body is in the process of climbing a slope, a wall, or stairs, the body posture of the swimming pool robot is changed, and the counterweight 206 moves freely according to the current state of the swimming pool robot, so that the valve is not subject to the pressure and is easily opened. In the process of climbing a slope, a wall, or stairs, the second flow channel is also opened accordingly.

[0096] This embodiment is another variation of the structure and opening method of the first valve. The structure and function of the swimming pool robot are consistent with those of the first embodiment and have the same technical effects. Therefore, they will not be described in detail in this embodiment.

[0097] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the technical solutions of the present invention, and are not intended to limit the specific implementation methods of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of the present invention shall be included within the scope of protection of the claims of the present invention.
