Description

Technical Field

[0001] This invention relates to the field of pool robots, and in particular to a pool robot for cleaning pools. Background Technology

[0002] Currently, many pools use automated pool cleaning robots for cleaning. These robots can clean pools without draining the water. They can move along the bottom and walls of the pool to clean it, changing the traditional method of manual scrubbing and water changing. This not only replaces the heavy labor of manual pool cleaning but also saves water resources.

[0003] Currently, automatic pool cleaning robots cannot conform well to the surface they walk on, especially when climbing walls, which affects the user experience. Furthermore, the current automatic pool cleaning robots can only climb vertically when climbing from the bottom of the wall, and cannot climb at an angle, which affects their cleaning effect.

[0004] Furthermore, when the main water inlet or filter basket of the current automatic water cleaning robot is blocked by dirt, it will be unable to take in water normally, affecting the cleaning efficiency and even shortening the service life of the cleaning robot. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the present invention provides a pool robot, which is provided with a first counterweight structure and a second counterweight structure. The two counterweights complement each other to stabilize the walking of the pool robot and enable the pool robot to climb the wall in an inclined manner.

[0006] To achieve the above objectives, the present invention employs the following technical solution:

[0007] A pool robot includes a robot body, a first counterweight structure, and a second counterweight structure, wherein the first counterweight structure and the second counterweight structure are disposed on the robot body and are respectively located on the left and right sides of the robot body.

[0008] The first counterweight structure includes a first counterweight mounting structure and a first counterweight. The first counterweight mounting structure has a first movable track, and the first counterweight can be movably set along the first movable track. Along the forward direction of the robot body, the first movable track gradually approaches the bottom surface of the robot body.

[0009] The second counterweight structure includes a second counterweight mounting structure and a second counterweight. The second counterweight mounting structure has a second movable track, and the second counterweight can be movably set along the second movable track. Along the forward direction of the robot body, the second movable track gradually approaches the bottom surface of the robot body.

[0010] The end of the first active track closer to the bottom surface of the robot body is the first track near end, and the end farther from the bottom surface of the robot body is the first track far end;

[0011] The end of the second active track closer to the bottom surface of the robot body is the near end of the second track, and the end farther away from the bottom surface of the robot body is the far end of the second track.

[0012] With the above structure, when the robot body is in the start-up or acceleration phase, the first counterweight, due to its own inertia, tends to move along the first active track towards the side closer to the first track. That is, if the first counterweight is located near the first track, the force it exerts on the side near the first track decreases; if the first counterweight is located far from the first track, the force it exerts on the side far from the first track increases. Alternatively, the first counterweight may move along the first active track towards the side closer to the first track due to its own inertia. The second counterweight behaves similarly. This balances the pool robot, making it more stable during operation.

[0013] When the robot body is in the deceleration phase, the first counterweight, due to its own inertia, tends to move along the first moving track away from the end of the track. That is, if the first counterweight is located near the end of the first track, the force it exerts on the side near the end of the first track increases; if the first counterweight is located far from the end of the first track, the force it exerts on the side far from the end of the first track decreases. Alternatively, the first counterweight may move along the first moving track away from the end of the first track due to its own inertia. The second counterweight behaves similarly. This balances the pool robot, making it more stable during operation.

[0014] When the pool robot is walking on a horizontal surface, and the main body of the robot is stopped or moving at a constant speed, the first counterweight structure and the second counterweight structure will be located at the near end of the first track and the near end of the second track respectively under the action of gravity, so that the overall center of gravity of the pool robot is lowered, making the pool robot run more stably.

[0015] When the pool robot is climbing the wall vertically and its centerline is perpendicular to the horizontal plane, and the robot body is at a stop or at a constant speed, the first counterweight structure and the second counterweight structure will be located at the far end of the first track and the far end of the second track respectively under the action of gravity. This makes the overall center of gravity of the pool robot lower when it is climbing the wall, so that the pool robot runs more smoothly and can prevent the pool robot from climbing out of the pool when it climbs out of the water.

[0016] During the process of the pool robot climbing the wall from the horizontal surface (i.e., the bottom of the pool), with both sides of the pool robot in contact with the wall simultaneously, the first counterweight moves along the first movable track toward the end furthest from the first track, while the second counterweight moves along the second movable track toward the end furthest from the second track; and finally, both reach the ends furthest from the first track and the ends furthest from the second track simultaneously, so that the pool robot can smoothly climb the wall from the horizontal surface (i.e., the bottom of the pool).

[0017] When the two sides of the pool robot are not in contact with the wall simultaneously, if the side with the first counterweight structure contacts the wall first, this side of the automatic cleaning pool robot will be lifted. At this time, the second counterweight in the pool robot will first move along the second movable track away from the end of the second track; the first counterweight will then move along the first movable track away from the end of the first track. This causes a change in the robot's balance point, and eventually brings the pool robot back to its upright position, i.e., its centerline is perpendicular to the horizontal plane. This allows the pool robot to smoothly climb up the wall from the horizontal plane, i.e., the bottom of the pool, while increasing its cleaning area. Similarly, if the side with the second counterweight structure contacts the wall first, the first counterweight in the pool robot will first move along the first movable track away from the end of the first track; the second counterweight will then move along the second movable track away from the end of the second track.

[0018] Furthermore, the first counterweight structure and the second counterweight structure are arranged symmetrically on the robot body.

[0019] The above structure makes the structure of the pool robot more reasonable, and allows the first and second counterweight structures to work together better to stabilize the pool robot.

[0020] Furthermore, the first counterweight structure and the second counterweight structure are positioned biased towards the bottom of the robot body.

[0021] The above structure makes the structure of the pool robot more reasonable, and the first and second counterweight structures can better stabilize the pool robot.

[0022] Furthermore, the first counterweight mounting structure is provided with a first cavity that matches the first counterweight, the first cavity is formed as the first movable track, and the first counterweight is movably disposed in the first cavity;

[0023] The second counterweight mounting structure is provided with a second cavity that matches the second counterweight. The second cavity forms the second movable track, and the second counterweight is movably disposed in the second cavity.

[0024] With the above structure, the first counterweight can be moved along the first movable track, and the second counterweight can be moved along the second movable track.

[0025] Furthermore, both the first and second counterweights are spherical.

[0026] The above structure allows the first counterweight to move more smoothly and better in the first movable track, preventing the first counterweight from getting stuck in the first movable track; the same applies to the second counterweight.

[0027] Furthermore, the first cavity is provided with a first communication hole that communicates with the outside; the second cavity is provided with a second communication hole that communicates with the outside.

[0028] The above structure makes the structure more reasonable.

[0029] Furthermore, both the first and second movable tracks are curved.

[0030] The above structure makes the arrangement of the first and second movable tracks more reasonable, and the first and second counterweight structures can better stabilize the pool robot.

[0031] Furthermore, the robot body has a first sidewall and a second sidewall that are arranged opposite to each other in the width direction; the first counterweight structure is arranged on the first sidewall, and the second counterweight is arranged on the second sidewall, that is, the first sidewall is the left sidewall of the robot body, and the second sidewall is the right sidewall of the robot body; typically, the first sidewall and the second sidewall are used to set up a walking mechanism, such as a tracked walking mechanism.

[0032] The above structure makes the positions of the first and second counterweight structures more reasonable, so as to stabilize the pool robot.

[0033] The first counterweight mounting structure includes a first counterweight mounting portion formed on the first sidewall and a first counterweight mounting cover that matches the first counterweight mounting portion. The first counterweight mounting cover is disposed on the first counterweight mounting portion, and the first counterweight mounting portion is recessed away from the first counterweight mounting cover to form a first counterweight groove one. Correspondingly, the first counterweight mounting cover is recessed away from the first counterweight mounting portion at a corresponding position to form a first counterweight groove two. The first counterweight groove one and the first counterweight groove two are combined to form the first movable track.

[0034] The second counterweight mounting structure includes a second counterweight mounting portion formed on the second sidewall and a second counterweight mounting cover that matches the second counterweight mounting portion. The second counterweight mounting cover is disposed on the second counterweight mounting portion, and the second counterweight mounting portion is recessed away from the second counterweight mounting cover to form a second counterweight groove one. Correspondingly, the second counterweight mounting cover is recessed away from the second counterweight mounting portion at a corresponding position to form a second counterweight groove two. The second counterweight groove one and the second counterweight groove two are combined to form the second movable track.

[0035] The above structure facilitates actual production and installation; and makes the arrangement of the first counterweight mounting structure and the second counterweight structure more reasonable; specifically, the first counterweight mounting cover is fixed to the first counterweight mounting part by fasteners such as screws; the second counterweight mounting cover is fixed to the second counterweight mounting part by fasteners such as screws.

[0036] The first connecting hole is provided on the first counterweight mounting cover, and the second connecting hole is provided on the second counterweight mounting cover.

[0037] Furthermore, the pool robot includes a water replenishment structure, the robot body includes a robot shell, and the robot shell is provided with a water inlet for connecting the inside of the robot shell and the outside of the robot shell; the water replenishment structure includes a cover that matches the water inlet for sealing the water inlet, the cover being disposed on one side inside the robot shell and being able to approach or move away from the water inlet along the axis of the water inlet.

[0038] With the above structure, the water inlet and the water replenishment structure are designed so that when the pool robot is in an abnormal water intake situation, the water replenishment structure can open the water inlet, allowing external water to enter the robot's shell through the water inlet, ensuring the normal operation of the pool robot and protecting it.

[0039] Specifically, when the main water inlet and filter basket in the water tank robot are not blocked, external water enters the robot shell through the water inlet, filling the robot shell with a large amount of water. After passing through the filter basket, the water is discharged from the outlet by the water pump. In the above case, the continuous flow of water inside the robot shell generates pressure to seal the water inlet with the cover. At this time, the water replenishment structure and the water inlet do not function.

[0040] When the main water inlet or filter basket in the water tank robot is not blocked, water cannot enter the robot housing through the main water inlet, resulting in a reduction in the water intake. However, the water pump still works and generates suction, causing the cover to move away from the water inlet to open the water inlet. External water can then enter the robot housing through the water inlet, achieving the purpose of replenishing the water tank robot with water.

[0041] Furthermore, the robot housing is provided with a main water inlet, and the water replenishment port is further away from the head of the robot housing relative to the main water inlet; the head and tail of the robot housing are based on the forward direction of the automatic cleaning pool robot.

[0042] When the pool robot climbs out of the water, the main water inlet will emerge first. At this time, a large amount of air will enter the robot's shell through the main water inlet, causing the pressure inside the robot's shell to decrease. Combined with the suction generated by the water pump, this causes the cover to move away from the water inlet to open the water inlet. Since the water inlet is further away from the head of the robot's shell than the main water inlet, the water inlet is still below the water surface. External water enters the robot's shell through the water inlet, achieving the purpose of replenishing the pool robot with water.

[0043] Furthermore, the pool robot includes a mounting part for movably mounting the cover, the mounting part being provided with a guide hole penetrating through itself, and the axis of the guide hole being collinear or parallel to the axis of the water inlet; the cover is provided with a guide rod that matches the guide hole and is slidably disposed in the guide hole.

[0044] With the above structure, the guide hole and the guide rod cooperate to guide the movement of the cover, making its movement more stable and reliable.

[0045] Furthermore, the water replenishment structure includes a limiting member, which is disposed at the end of the guide rod away from the cover member, and the diameter of the limiting member is larger than the diameter of the guide hole.

[0046] With the above structure, the limiting member restricts the range of motion of the guide rod, that is, it restricts the range of motion of the cover. Specifically, the limiting member is installed on the guide rod by fasteners such as screws. The above structure is actually installed in production.

[0047] Furthermore, the axis of the guide hole is collinear with the axis of the water inlet; the guide rod is located at the center of the cover.

[0048] With the above structure, the guide rod and the guide hole are more rationally positioned, and the guiding cooperation between the two makes the movement of the cover more stable and reliable.

[0049] Furthermore, the mounting part is located at the axis of the water inlet and has a guide hole at the axis of the water inlet. The mounting part extends outward and has one or more connecting arms. The end of the connecting arm away from the mounting part is connected to the robot housing.

[0050] The above structure enables the mounting part to be connected and fixed to the robot shell.

[0051] Furthermore, the mounting part is located at the center of the water inlet or on one side of the robot housing.

[0052] Specifically, the mounting part is located at the center of the water inlet, and one end of its connecting arm away from the mounting part is connected to the inner wall of the water inlet; multiple connecting arms are provided, and several connecting arms are distributed at intervals on the outer periphery of the mounting part; the outside and inside of the robot shell are connected through the water inlet between adjacent connecting arms; more specifically, several connecting arms are equally spaced on the outer periphery of the mounting part, and the number of connecting arms is four.

[0053] Furthermore, a water inlet enclosure is formed around the water inlet protrusion on the outer side of the robot housing. The limiting member is located inside the water inlet enclosure and extends radially outward to fit or gap fit with the inner sidewall of the water inlet enclosure. The limiting member is provided with one or more water inlet holes penetrating itself.

[0054] With the above structure, the side of the water inlet facing outward is surrounded by the water inlet enclosure and the limiting member. External water can only flow to the water inlet through the water inlet hole on the limiting member. The water inlet hole is designed to filter the water entering from the outside, that is, impurities in the water larger than the diameter of the water inlet hole cannot pass through the water inlet hole, thus preventing large impurities from entering the robot shell and affecting the operation of the pool robot.

[0055] Furthermore, along the radial outward direction of the limiting member, the limiting member gradually approaches the water inlet, that is, the center of the limiting member has an arc shape that is further away from the water inlet relative to the surrounding area.

[0056] The above structure makes the structure of the limiting member more reasonable.

[0057] Furthermore, the cap has a tendency to move toward the water inlet when it is away from the water inlet.

[0058] The above structure enables the cover to be reset.

[0059] Furthermore, the water replenishment structure includes an elastic element that acts on the cap to cause it to tend to move toward the water replenishment port when it is away from the water replenishment port.

[0060] Using the above structure, the elastic element enables the cap to be reset.

[0061] Specifically, the elastic element is a spring, and its two ends abut against the limiting element and the mounting part, respectively.

[0062] Furthermore, the water inlets are provided on the left and right sidewalls of the robot housing, and the water inlets on the first and second sidewalls are arranged symmetrically from left to right; each water inlet is provided with a corresponding water replenishment structure; the first sidewall of the robot body is the left sidewall of the robot housing, and the second sidewall of the robot body is the right sidewall of the robot housing.

[0063] The above structure makes the structure of the pool robot more reasonable.

[0064] The water tank robot of this invention includes a swimming pool robot.

[0065] Compared with the prior art, the present invention has the following beneficial effects:

[0066] (1) The pool robot of the present invention is provided with a first counterweight structure and a second counterweight structure. The two counterweights complement each other to stabilize the walking of the pool robot and enable the pool robot to climb the wall in an inclined manner.

[0067] (2) The water tank robot of the present invention is provided with a water inlet and a water supply structure, so that when the water tank robot is in an abnormal water intake situation, the water supply structure can open the water inlet, and external water can enter the robot shell through the water inlet, ensuring the normal operation of the water tank robot and protecting the water tank robot.

[0068] (3) The pool robot of the present invention has a reasonable structure. Attached Figure Description

[0079] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0080] like Figure 1 As shown in Figure 9, a pool robot includes a robot body 1, a first counterweight structure 2, and a second counterweight structure 3. The first counterweight structure 2 and the second counterweight structure 3 are disposed on the robot body 1 and are respectively located on the left and right sides of the robot body 1.

[0081] The first counterweight structure 2 includes a first counterweight mounting structure 201 and a first counterweight 202. The first counterweight mounting structure 201 has a first movable track 2011, and the first counterweight 202 can be movably set along the first movable track 2011. Along the forward direction of the robot body 1, the first movable track 2011 gradually approaches the bottom surface of the robot body 1.

[0082] The second counterweight structure 3 includes a second counterweight mounting structure 301 and a second counterweight 302. The second counterweight mounting structure 301 has a second movable track 3011, and the second counterweight 302 can be movably set along the second movable track 3011. Along the forward direction of the robot body 1, the second movable track 3011 gradually approaches the bottom surface of the robot body 1.

[0083] The first active track 2011 is defined as the first track approach end 2011a, which is closer to the bottom surface of the robot body 1, and the first track away end 2011b, which is farther from the bottom surface of the robot body.

[0084] The end of the second active track 3011 that is closer to the bottom surface of the robot body 1 is the second track near end 3011a, and the end that is farther away from the bottom surface of the robot body is the second track far end 3011b.

[0085] With the above structure, when the robot body 1 is in the start-up or acceleration phase, the first counterweight 202, due to its own inertia, tends to move along the first active track 2011 towards the side away from the first track's near end 2011a. That is, if the first counterweight 202 is located at the first track's near end 2011a, the force it applies to the first track's near end 2011a decreases; if the first counterweight 202 is located at the first track's far end 2011b, the force it applies to the first track's far end 2011b increases. Alternatively, the first counterweight 202, due to its own inertia, moves along the first active track 2011 towards the side away from the first track's near end 2011a. The second counterweight 302 behaves similarly. This balances the pool robot, making it more stable during operation.

[0086] When the robot body 1 is in the deceleration phase, the first counterweight 202, due to its own inertia, tends to move along the first active track 2011 towards the side away from the far end 2011b of the first track. That is, if the first counterweight 202 is located at the near end 2011a of the first track, the force it applies to the side near the first end 2011a increases; if the first counterweight 202 is located at the far end 2011b of the first track, the force it applies to the side far from the first end 2011b decreases. Alternatively, the first counterweight 202, due to its own inertia, moves along the first active track 2011 towards the side away from the far end 2011b of the first track. The second counterweight 302 behaves similarly. This balances the pool robot, making the robot more stable during operation.

[0087] When the pool robot is walking on a horizontal surface, and the robot body 1 is at a stop or at a constant speed, the first counterweight structure 2 and the second counterweight structure 3 will be located at the first track near end 2011a and the second track near end 3011a respectively under the action of gravity, so that the overall center of gravity of the pool robot is lowered, making the pool robot run more stably.

[0088] When the pool robot is climbing the wall vertically and its centerline is perpendicular to the horizontal plane, and the robot body 1 is at a stop or at a constant speed, the first counterweight structure 2 and the second counterweight structure 3 will be located at the far end 2011b of the first track 2011 and the far end 3011b of the second track 3011 respectively under the action of gravity. This makes the overall center of gravity of the pool robot lower when it is climbing the wall, so that the pool robot runs more smoothly and can prevent the pool robot from climbing out of the pool when it climbs out of the water.

[0089] like Figure 8 As shown, during the process of the pool robot climbing the wall from the horizontal surface (i.e., the bottom of the pool), with both sides of the pool robot in contact with the wall simultaneously, the first counterweight 202 moves along the first movable track 2011 towards the side away from the first track end 2011b, while the second counterweight 302 moves along the second movable track 3011 towards the side away from the second track end 3011b; and finally, both reach the side away from the first track end 2011b and the side away from the second track end 3011b simultaneously, enabling the pool robot to smoothly climb the wall from the horizontal surface (i.e., the bottom of the pool).

[0090] like Figure 9 As shown, when the two sides of the pool robot are not in contact with the wall simultaneously, when the side with the first counterweight structure 2 contacts the wall first, the side of the automatic cleaning pool robot with the first counterweight structure 2 is lifted. At this time, the second counterweight 302 in the pool robot will first move along the second moving track 3011 towards the side away from the second track end 3011b; the first counterweight 202 will then move along the first moving track 2011 towards the side away from the first track end 2011b; causing the robot's balance point to change, and Ultimately, this allows the pool robot to return to its upright position, meaning its centerline is perpendicular to the horizontal plane. This enables the pool robot to smoothly climb up the wall from the horizontal plane, i.e., the bottom of the pool, while increasing its cleaning area. Similarly, when the side with the second counterweight structure 3 first contacts the wall, the first counterweight 202 in the pool robot will first move along the first moving track 2011 towards the side furthest from the first track 2011b. The second counterweight 302 will then move laterally along the second moving track 3011 towards the side furthest from the second track 3011b.

[0091] Furthermore, the first counterweight structure 2 and the second counterweight structure 3 are arranged symmetrically on the robot body 1.

[0092] The above structure makes the structure of the pool robot more reasonable, and allows the first counterweight structure 2 and the second counterweight structure 3 to work together better to stabilize the pool robot.

[0093] Furthermore, the first counterweight structure 2 and the second counterweight structure 3 are positioned biased towards the bottom of the robot body 1.

[0094] The above structure makes the structure of the pool robot more reasonable, and the first counterweight structure 2 and the second counterweight structure 3 can better stabilize the pool robot.

[0095] Furthermore, the first counterweight mounting structure 201 is provided with a first cavity that matches the first counterweight 202. The first cavity is formed as the first movable track 2011, and the first counterweight 202 is movably disposed in the first cavity.

[0096] The second counterweight mounting structure 301 is provided with a second cavity that matches the second counterweight 302. The second cavity is formed as the second movable track 3011, and the second counterweight 302 is movably disposed in the second cavity.

[0097] With the above structure, the first counterweight 202 can be movably set along the first movable track 2011, and the second counterweight 302 can be movably set along the second movable track 3011.

[0098] Furthermore, the first counterweight 202 is spherical, and the second counterweight 302 is spherical.

[0099] By adopting the above structure, the first counterweight 202 can move more smoothly and better in the first movable track 2011, avoiding the first counterweight 202 from getting stuck in the first movable track 2011; the second counterweight 302 is similar.

[0100] Furthermore, the first cavity is provided with a first communication hole 2015 communicating with the outside; the second cavity is provided with a second communication hole 3015 communicating with the outside.

[0101] The above structure makes the structure more reasonable.

[0102] Furthermore, the first movable track 2011 has an arc, and the second movable track 3011 has an arc.

[0103] The above structure makes the structural arrangement of the first movable track 2011 and the second movable track 3011 more reasonable, and the first counterweight structure 2 and the second counterweight structure 3 can better stabilize the pool robot.

[0104] Furthermore, the robot body 1 has a first sidewall 101 and a second sidewall 102 arranged opposite to each other in the width direction; the first counterweight structure 2 is disposed on the first sidewall 101, and the second counterweight 302 is disposed on the second sidewall 102, that is, the first sidewall 101 is the left sidewall of the robot body 1, and the second sidewall 102 is the right sidewall of the robot body 1; typically, the first sidewall 101 and the second sidewall 102 are used to set up a walking mechanism, such as a tracked walking mechanism.

[0105] The above structure makes the positions of the first counterweight structure 2 and the second counterweight structure 3 more reasonable, so as to stabilize the pool robot.

[0106] The first counterweight mounting structure 201 includes a first counterweight mounting portion 2013 formed on the first sidewall 101 and a first counterweight mounting cover 2014 matching the first counterweight mounting portion 2013. The first counterweight mounting cover 2014 covers the first counterweight mounting portion 2013. The first counterweight mounting portion 2013 is recessed away from the first counterweight mounting cover 2014 to form a first counterweight groove 1 2013a. Correspondingly, the first counterweight mounting cover 2014 is recessed away from the first counterweight mounting portion 2013 at a corresponding position to form a first counterweight groove 2 2014a. The first counterweight groove 1 2013a and the first counterweight groove 2 2014a combine to form the first movable track 2011.

[0107] The second counterweight mounting structure 301 includes a second counterweight mounting portion 3013 formed on the second sidewall 102 and a second counterweight mounting cover 3014 that matches the second counterweight mounting portion 3013. The second counterweight mounting cover 3014 covers the second counterweight mounting portion 3013. The second counterweight mounting portion 3013 is recessed away from the second counterweight mounting cover 3014 to form a second counterweight groove 3013a. Correspondingly, the second counterweight mounting cover 3014 is recessed away from the second counterweight mounting portion 3013 at a corresponding position to form a second counterweight groove 3014a. The second counterweight groove 3013a and the second counterweight groove 3014a are combined to form the second movable track 3011.

[0108] The above structure facilitates actual production and installation; and makes the arrangement of the first counterweight mounting structure 201 and the second counterweight structure 3 more reasonable; specifically, the first counterweight mounting cover 2014 is fixed to the first counterweight mounting part 2013 by fasteners such as screws; the second counterweight mounting cover is fixed to the second counterweight mounting part 3013 by fasteners such as screws.

[0109] The first connecting hole 2015 is provided on the first counterweight mounting cover 2014, and the second connecting hole 3015 is provided on the second counterweight mounting cover 3014.

[0110] like Figure 3 As shown in Figure 7, the pool robot further includes a water replenishment structure 4, and the robot body 1 includes a robot shell 103. The robot shell 103 is provided with a water inlet 1031 for connecting the inside of the robot shell 103 and the outside of the robot shell 103. The water replenishment structure 4 includes a cover 401 that matches the water inlet 1031 for sealing the water inlet 1031. The cover 401 is disposed on one side inside the robot shell 103 and can move closer to or away from the water inlet 1031 along the axis of the water inlet 1031.

[0111] With the above structure, the water inlet 1031 and the water replenishment structure 4 are designed so that when the pool robot is in an abnormal water intake situation, the water replenishment structure 4 can open the water inlet 1031, and external water can enter the robot shell 103 through the water inlet 1031, ensuring the normal operation of the pool robot and protecting the pool robot.

[0112] Specifically, when the main water inlet 1033 and the filter basket in the water tank robot are not blocked, external water enters the robot housing 103 through the water inlet, filling the robot housing 103 with a large amount of water. After passing through the filter basket, the water is discharged from the outlet by a water pump. In this case, the continuous flow of water inside the robot housing 103 generates pressure, which seals the water inlet 1031 with the cover 401. At this time, the water replenishment structure 4 and the water inlet 1031 do not function. Figure 7 As shown;

[0113] When the main water inlet 1033 or filter basket in the water tank robot is not blocked, water cannot enter the robot housing 103 through the main water inlet 1033, resulting in a reduction in water intake. However, the water pump still works, generating suction, causing the cover 401 to move away from the water inlet 1031 to open the water inlet 1031. External water can then enter the robot housing 103 through the water inlet 1031, achieving the purpose of replenishing the water tank robot. Figure 6 As shown.

[0114] Furthermore, the robot housing 103 is provided with a main water inlet 1033, and the water replenishment inlet 1031 is further away from the head of the robot housing 103 relative to the main water inlet 1033; the head and tail of the robot housing 103 are based on the forward direction of the automatic cleaning pool robot.

[0115] When the pool robot climbs out of the water, the main water inlet 1033 will emerge first. At this time, a large amount of air will enter the robot shell 103 through the main water inlet 1033, causing the pressure inside the robot shell 103 to decrease. Combined with the suction generated by the operation of the water pump, the cover 401 moves away from the water inlet 1031 to open the water inlet 1031. Since the water inlet 1031 is further away from the head of the robot shell 103 than the main water inlet 1033, the water inlet 1031 is still below the water surface. External water enters the robot shell 103 through the water inlet 1031, achieving the purpose of replenishing the pool robot with water.

[0116] Furthermore, the pool robot includes a mounting part 5 for movably mounting the cover 401. The mounting part 5 is provided with a guide hole 501 penetrating through it, and the axis of the guide hole 501 is collinear or parallel to the axis of the water inlet 1031. The cover 401 is provided with a guide rod 402 that matches the guide hole 501 and is slidably disposed in the guide hole 501.

[0117] With the above structure, the guide hole 501 and the guide rod 402 cooperate to guide the movement of the cover 401, making its movement more stable and reliable.

[0118] Furthermore, the water replenishment structure 4 includes a limiting member 403, which is disposed at the end of the guide rod 402 away from the cover member 401, and the diameter of the limiting member 403 is larger than the diameter of the guide hole 501.

[0119] With the above structure, the limiting member 403 restricts the range of motion of the guide rod 402, that is, it restricts the range of motion of the cover member 401; specifically, the limiting member 403 is installed on the guide rod 402 by fasteners such as screws. The above structure is actually installed in production.

[0120] Furthermore, the axis of the guide hole 501 is collinear with the axis of the water inlet 1031; the guide rod 402 is located at the center of the cover 401.

[0121] With the above structure, the guide rod 402 and the guide hole 501 are set more reasonably, and the movement of the cover 401 is more stable and reliable under the guidance and cooperation of the two.

[0122] Furthermore, the mounting part 5 is located at the axis of the water inlet 1031 and has a guide hole 501 at the axis of the water inlet 1031. The mounting part 5 extends outward and has one or more connecting arms 502. The end of the connecting arm 502 away from the mounting part 5 is connected to the robot housing 103.

[0123] The above structure enables the mounting part 5 to be connected and fixed to the robot housing 103.

[0124] Furthermore, the mounting part 5 is located at the center of the water inlet 1031 or on one side of the outside of the robot housing 103.

[0125] Specifically, the mounting part 5 is located at the center of the water inlet 1031, and one end of its connecting arm 502 away from the mounting part 5 is connected to the inner wall of the water inlet 1031; multiple connecting arms 502 are provided, and several connecting arms 502 are distributed at intervals on the outer periphery of the mounting part 5; the outside and inside of the robot shell 103 are connected through the water inlets 1031 between adjacent connecting arms 502; more specifically, several connecting arms 502 are equally spaced on the outer periphery of the mounting part 5, and the number of connecting arms 502 is four.

[0126] Furthermore, a water inlet enclosure 1032 is formed by protrusions around the water inlet 1031 on the outer surface of the robot housing 103. The limiting member 403 is located inside the water inlet enclosure 1032, and the limiting member 403 extends radially outward to fit or gap fit with the inner sidewall of the water inlet enclosure 1032. The limiting member 403 is provided with one or more water inlet holes 4031 penetrating through itself.

[0127] With the above structure, the side of the water inlet 1031 facing outward is surrounded by the water inlet enclosure and the limiting member 403. External water can only flow to the water inlet 1031 through the water inlet hole 4031 on the limiting member 403. The water inlet hole 4031 is set to filter the water entering from the outside, that is, impurities in the water larger than the diameter of the water inlet hole 4031 cannot pass through the water inlet hole 4031, thus preventing large impurities from entering the robot shell 103 and affecting the operation of the pool robot.

[0128] Furthermore, along the radial outward direction of the limiting member 403, the limiting member 403 gradually approaches the water inlet 1031, that is, the center of the limiting member 403 is an arc shape with the center further away from the water inlet 1031 relative to the surrounding area.

[0129] The above structure makes the structure of the limiting member 403 more reasonable.

[0130] Furthermore, the cover 401 has a tendency to move toward the water inlet 1031 when it is away from the water inlet 1031.

[0131] The above structure enables the cover 401 to be reset.

[0132] Furthermore, the water replenishment structure 4 includes an elastic element 404, which acts on the cover 401 to make it tend to move toward the water replenishment port 1031 when it is away from the water replenishment port 1031.

[0133] Using the above structure, the elastic element 404 is used to reset the cover 401;

[0134] Specifically, the elastic element 404 is a spring, and its two ends abut against the limiting element 403 and the mounting part 5, respectively.

[0135] Furthermore, the robot housing 103 has water inlets 1031 on its left and right sidewalls, and the water inlets 1031 on the first sidewall 101 and the second sidewall 102 are arranged symmetrically from left to right; each water inlet 1031 is provided with a corresponding water replenishment structure 4; the first sidewall 101 of the robot body 1 is the left sidewall of the robot housing 103, and the second sidewall 102 of the robot body 1 is the right sidewall of the robot housing 103.

[0136] The above structure makes the structure of the pool robot more reasonable.

[0137] The water tank robot of this invention includes a swimming pool robot.

[0138] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
