Description

Automatic pool cleaning device

[0001] [Amended 28.05.2026 in accordance with Rule 26] This application claims priority to Chinese Patent Application No. 2025206301006, filed April 3, 2025; Chinese Patent Application No. 202522178333X, filed October 15, 2025; and Chinese Patent Application No. 2025224580549, filed November 19, 2025, the disclosures of which are incorporated herein by reference in their entirety. Technical Field

[0002] This application relates to the field of cleaning device technology, and in particular to an automatic water tank cleaning device. Background Technology

[0003] With the advancement of computers, water surface cleaning robots have become increasingly diverse in design, with various opening methods for their water intake ports, such as rotary doors and front-opening doors. These opening methods prevent the robot from cleaning water surfaces wider than the door's width. For example, with a front-opening door type water intake port, the door can easily get stuck and fail to close when the robot tries to clean through it. Furthermore, these opening methods create resistance when the robot moves on and underwater, making movement difficult. Summary of the Invention

[0004] According to one aspect of this disclosure, an automatic pool cleaning device is provided, comprising: a housing; a water surface suction port located at the head of the housing for sucking up dirt on the water surface; a filter device, at least partially located inside the housing, for filtering dirt entering the water surface suction port; a movable guide plate disposed on the housing; and a drive device for controlling the movable guide plate to move and switch between a first position and a second position, wherein when the movable guide plate is in the first position, the movable guide plate can guide water flow or dirt on the water surface into the water surface suction port; and when the movable guide plate is in the second position, the movable guide plate closes the water surface suction port.

[0005] Furthermore, the movable guide plate includes two plates, which are respectively disposed on both sides of the housing, and the driving device can synchronously or independently control the movement of the two movable guide plates.

[0006] Furthermore, when the movable guide plate is in the first position, the movable guide plate extends beyond the side or front end of the housing.

[0007] Furthermore, at least a portion of the movable guide plate is made of a flexible material.

[0009] Furthermore, it also includes a controller, which is used to determine whether the automatic water tank cleaning device meets a first preset condition for moving from the first position to the second position, and to determine whether the automatic water tank cleaning device meets a second preset condition for moving from the first position to the third position. If the first preset condition is met, the driving device controls the movable guide plate to move from the first position to the second position; and if the second preset condition is met, the driving device controls the movable guide plate to move from the first position to the third position.

[0010] Furthermore, the first preset condition includes: the automatic pool cleaning device entering underwater operation mode; or the automatic pool cleaning device performing a backward movement.

[0011] Furthermore, the second preset condition includes: the automatic pool cleaning device entering a state of moving along the pool wall; or detecting an obstacle within a preset distance range from the automatic pool cleaning device.

[0012] Furthermore, when the movable guide plate is in the first position, the movable guide plate extends beyond the side of the housing; when the movable guide plate is in the third position, the movable guide plate does not extend beyond the side of the housing.

[0013] Furthermore, the movement includes rotation.

[0014] Furthermore, the controller can control the movable guide plate corresponding to the detected direction of the obstacle to move to the third position.

[0015] Furthermore, when the two movable guide plates are in the first position, the included angle between them ranges from 45 degrees to 180 degrees.

[0016] Furthermore, it also includes a sensor, wherein when the sensor detects an object to be cleaned on the water surface, the driving device controls the movable guide plate to move to a second position and then to a first position, so that the object to be cleaned is propelled into the water surface suction port by the movable guide plate.

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] This application provides a control method for an automatic pool cleaning device. It is understood that the automatic pool cleaning device is capable of cleaning a pool. The pool is, for example, a pool-shaped structure. The pool-shaped structure can be a swimming pool, a water storage tank, a spa pool, a water tank, a water storage trough, etc. The automatic pool cleaning device can be a device such as an automatic cleaning device or a pool cleaning robot, capable of cleaning the pool-shaped structure. This application does not limit the specific presentation of the automatic pool cleaning device or the pool-shaped structure, as long as the principle of this application is achieved. In the following description, unless otherwise specified, a robot will be used as an example of the automatic pool cleaning device, and a swimming pool will be used as an example of a pool or pool-shaped structure.

[0047] Please refer to Figures 1-7 for the following content.

[0048] The automatic water tank cleaning device 10 will now be described in detail with reference to the accompanying drawings.

[0049] Figure 1 is a schematic diagram of the structure of an automatic water tank cleaning device 10 according to an embodiment of this application. As shown in Figure 1, the automatic water tank cleaning device 10 includes: a housing 100; a water surface suction port 111 located at the head of the housing 100 for sucking up dirt on the water surface; a filter device 114 located at least partially inside the housing 100 for filtering dirt entering the water surface suction port 111; and a movable guide plate 110 disposed on the housing 100. A driving device 210 is used to control the movement of the movable guide plate 110 to switch between a first position and a second position, wherein, when the movable guide plate 110 is in the first position, the movable guide plate 110 can guide water flow or dirt on the water surface into the water surface suction port 111; and, when the movable guide plate 110 is in the second position, the movable guide plate 110 closes the water surface suction port 111.

[0050] Specifically, the housing 100 constitutes the outer shell of the automatic pool cleaning device 10. The housing 100 provides protection and support for the components inside the automatic pool cleaning device 10. Furthermore, various components such as the water surface suction port 111, the bottom suction port, and sensors can be installed on the housing 100 to realize various functions of the automatic pool cleaning device.

[0051] The water surface intake 111 is located at the head of the housing 100. As shown in Figure 1, the head of the automatic pool cleaning device 10 points to the left as shown in Figure 1, and the water surface intake 111 is located at the head of the automatic pool cleaning device 10 shown in Figure 1. When the automatic pool cleaning device 10 cleans dirt on the water surface, a portion of its structure floats on the water surface. The water surface intake 111 is designed to suck up dirt from the water surface and guide pool water and dirt from the water surface intake 111 into the interior of the automatic pool cleaning device 10, for example, into the filter device 114. The water surface intake 111 has a certain height and length so that dirt can pass smoothly through the water surface intake 111. As shown in Figure 1, the water surface suction port 111 is located at the upper part of the automatic water cleaning device 10. In other words, the water surface suction port 111 is located at the upper part of the head of the automatic water cleaning device 10, so that when the automatic water cleaning device 10 floats on the water surface, at least a portion of the water surface suction port 111 can overlap with the water surface. Taking Figure 1 as an example, along the height direction of the water surface suction port 111, at least a portion of the water surface suction port 111 can overlap with the water surface.

[0052] The filter device 114 is located inside the housing 100. The filter device 114 is capable of filtering water and dirt. The filter device 114 will retain the dirt in the filter device 114, while the clean water will be discharged into the water tank through the drainage device.

[0053] A movable guide plate 110 is mounted on the housing 100. As shown in Figure 1, the movable guide plate 110 is located on the upper part of the automatic water tank cleaning device 10, and a rotating shaft can be provided on one side of the movable guide plate 110, and this rotating shaft is connected to the housing 100. For example, the rotating shaft can be located on the housing 100 and at the edge of the water surface suction port 111; the rotating shaft can also be located on the housing 100 and at a certain distance from the edge of the water surface suction port 111. In other words, the movable guide plate 110 can also be located on the upper part of the housing 100 and the rotating shaft on one side of the movable guide plate 110 is a certain distance away from the water surface suction port 111. Depending on the position of the rotating shaft, and because the movable guide plate 110 has a certain length and width, the position of the movable guide plate 110 relative to the water surface suction port 111 will also be different, as long as the movable guide plate 110 can be opened and closed to open and close the water surface suction port 111. For example, the pivot of one side of the movable guide plate can be set at the side edge of the water surface intake 111, so that the movable guide plate is located in front of the water surface intake 111.

[0054] When cleaning dirt, the movable guide plate 110 of the automatic water tank cleaning device 10 can be in the open state, in which the movable guide plate 110 can push the dirt inward into the water surface suction port 111; the movable guide plate 110 can also be in the closed state, in which the movable guide plate 110 can prevent dirt in the filter device 114 from flowing out.

[0055] As shown in Figures 1 to 4, there are two movable guide plates 110, which are respectively disposed on both sides of the housing 100. The drive device 210 can synchronously or independently control the movement of the two movable guide plates (112, 113).

[0056] Specifically, the automatic water tank cleaning device 10 has two movable guide plates (112, 113), namely the first movable guide plate 112 and the second movable guide plate 113. As shown in Figures 1 and 2, the first movable guide plate 112 and the second movable guide plate 113 are located on both sides of the housing 100 (i.e., the left and right sides). If both the first movable guide plate 112 and the second movable guide plate 113 are opened, the two movable guide plates (112, 113) form a trapezoidal side shape with respect to the water surface intake 111, so that when viewed from the water surface intake 111 outwards, the two movable guide plates (112, 113) form a shape similar to an "open mouth". The movable guide plate 110 in the open state can push dirt inwards (i.e. towards the water surface intake 111), so that the dirt can gather or move closer to the water surface intake 111.

[0057] Figure 5 shows a schematic diagram of the drive unit 210 controlling the movable guide plate 110 to be in a first position. The drive unit 210 includes a motor and a drive shaft. In one case, the drive unit 210 can independently control the movement of the first movable guide plate 112; in another case, the drive unit 210 can independently control the movement of the second movable guide plate 113; in yet another case, the drive unit 210 can simultaneously control the movement of both movable guide plates (112, 113).

[0058] The drive unit 210 is used to control the movement of the movable guide plate 110 so as to switch between a first position and a second position.

[0059] The movable guide plate 110 and its various positions will be described in detail with reference to Figures 1 to 4. Figures 1 and 3 show schematic diagrams of the movable guide plate 110 in the first position. As shown in Figures 1 and 3, the first position is the position when the movable guide plate 110 is in the open state; in other words, the movable guide plate 110 is in the first position when it is in the open state.

[0060] As shown in Figure 1, when the movable guide plate 110 is in the first position, it extends beyond the side or front end of the housing 100. Specifically, when the movable guide plate 110 is in the first position, it is in an open state, allowing dirt to enter the water intake 111. As shown in Figures 1 and 3, when the movable guide plate 110 is in the first position, the included angle between the two movable guide plates (112, 113) is between 45 degrees and 180 degrees. The movable guide plate 110 extends beyond the side or front end of the housing 100.

[0061] Figures 2 and 4 show schematic diagrams of the movable guide plate 110 in the second position. As shown in Figures 2 and 4, the second position is the position when the movable guide plate 110 is in the closed state; in other words, the movable guide plate 110 is in the second position when it is in the closed state. The above descriptions of the first and second positions are exemplary. Those skilled in the art can select specific settings for the first and second positions based on the principles of this application, as long as the technical principles of this application are implemented.

[0062] The drive unit 210 can control the movable guide plate 110 to switch between a first position and a second position. Specifically, if the movable guide plate 110 is in the first position, the drive unit 210 can switch the movable guide plate 110 from the first position to the second position. Conversely, the drive unit 210 can switch the movable guide plate 110 from the second position to the first position.

[0063] When the movable guide plate 110 is in the first position, the movable guide plate 110 can guide water flow or dirt on the water surface into the water surface suction port 111; and when the movable guide plate 110 is in the second position, the movable guide plate 110 closes the water surface suction port 111.

[0064] As described above, when the movable guide plate 110 is in the first position, the movable guide plate 110 is in the open state. In this open state, dirt on the water surface can enter the water surface intake 111 with the water flow. In this open state, the movable guide plate 110 forms a shape similar to an "open mouth" relative to the water surface intake 111. Thus, the movable guide plate 110 can guide the water flow / dirt into the water surface intake 111.

[0065] As described above, when the movable guide plate 110 is in the second position, the movable guide plate 110 is in the closed state, that is, the movable guide plate 110 closes the water surface intake port 111, thereby preventing dirt from entering the filter device 114.

[0066] The drive device 210 can also control the movement of the movable guide plate 110 to switch between the first position and the third position.

[0067] Figure 7 shows a schematic diagram of the movable guide plate 110 in the third position. As shown in Figure 7, the opening degree of the movable guide plate 110 in the third position is less than that in the first position. For example, the two movable guide plates (112, 113) are in a parallel or substantially parallel state, with an included angle of 0 degrees or close to 0 degrees. The above description of the third position is merely exemplary, and those skilled in the art can set the third position according to the technical principles of this application.

[0068] Specifically, the drive device 210 is tightly connected to the movable guide plate 110. During the movement of the automatic pool cleaning device 10 along the edge, the movable guide plate 110 is in a first position. As mentioned above, in the first position, the movable guide plate 110 opens to a greater extent outward. In order to avoid the movable guide plate 110, which opens to a greater extent outward, from touching the pool wall or other obstacles, the drive device 210 can reduce the opening extent of the movable guide plate 110 when it is close to the pool wall or other obstacles. That is, the drive device 210 controls the movable guide plate 110 to switch from the first position to the third position.

[0069] When the movable guide plate 110 is in the first position, the movable guide plate 110 extends beyond the side of the housing 100; when the movable guide plate 110 is in the third position, the movable guide plate 110 does not extend beyond the side of the housing 100.

[0070] Specifically, as shown in Figures 1 and 5, when the movable guide plate 110 is in the first position, the two movable guide plates (112, 113) open to both sides respectively, and the movable guide plate 110 extends beyond the side of the housing 100; as shown in Figure 7, when the movable guide plate 110 is in the third position, the two movable guide plates (112, 113) are parallel or substantially parallel to each other, and the included angle between them is 0 degrees or close to 0 degrees. Thus, during the automatic cleaning process of the pool, the two movable guide plates (112, 113) do not extend beyond the side of the housing 100, which can prevent the two movable guide plates (112, 113) from touching the pool wall or obstacles.

[0071] The automatic water tank cleaning device 10 further includes a controller, which is used to determine whether the automatic water tank cleaning device 10 meets a first preset condition for moving from the first position to the second position, and to determine whether the automatic water tank cleaning device 10 meets a second preset condition for moving from the first position to the third position. If the first preset condition is met, the drive device 210 controls the movable guide plate 110 to move from the first position to the second position; and if the second preset condition is met, the drive device 210 controls the movable guide plate 110 to move from the first position to the third position.

[0072] The first preset conditions include: the automatic pool cleaning device 10 entering underwater operation mode; or the automatic pool cleaning device 10 performing a backward movement.

[0073] Specifically, the first preset condition is that the automatic pool cleaning device 10 initially cleans dirt on the water surface, gradually moves to the bottom of the pool to clean dirt, or the automatic pool cleaning device 10 performs a reverse action. The controller can determine that the state of the pool cleaning device 10 has changed, that is, the automatic pool cleaning device 10 has entered the underwater operation state. The automatic pool cleaning device 10 needs to close the water surface inlet 111 and only work from the bottom inlet. Then the controller can control the movable guide plate 110 to move from the first position to the second position.

[0074] If the automatic water cleaning device 10 encounters an obstacle during the water surface cleaning process, it can reverse. During the reversing process, or before the reversing action begins, the movable guide plate 110 needs to move from the first position (as shown in Figure 5) to the second position (as shown in Figure 6), that is, the water surface inlet 111 needs to be closed to prevent dirt entering the filter device 114 from flowing out of the water surface inlet 111 again.

[0075] The second preset condition includes: the automatic water cleaning device 10 entering a state of moving along the pool wall; or detecting an obstacle within a preset distance range from the automatic water cleaning device 10.

[0076] For example, the automatic pool cleaning device 10 cleans dirt in the center of the water surface and gradually moves to a position where the distance between the pool wall and the machine body is very close or / and the corner of the pool wall. The controller determines that the movable guide plate 110 is close to the pool wall. In order to prevent the movable guide plate 110 from hitting the pool wall, the drive device 210 can control the movable guide plate 110 to move from the first position to the third position (i.e., retract the movable guide plate 110 inward to a certain extent) to prevent it from touching the pool wall.

[0077] When the automatic pool cleaning device 10 detects an obstacle within a preset distance during the water surface cleaning process, in order to avoid the movable guide plate 110 from colliding with the obstacle during the moving cleaning process, the automatic pool cleaning device 10 can move the movable guide plate 110 from the first position to the third position (that is, retract the movable guide plate 110 inward to a certain extent) to prevent it from touching the obstacle.

[0078] At least a portion of the movable guide plate 110 is made of a flexible material.

[0079] Specifically, the movable guide plate 110 can be made of a material with significant properties such as softness, flexibility, and deformability. Such materials can withstand a considerable degree of deformation without breaking when subjected to external forces. More importantly, after the external force is removed, these materials can typically return to their original shape, or at least maintain a stable deformed state. For example, when the movable guide plate 110 is in the open state, this flexible material can be folded to reduce resistance from the movable guide plate 110 during movement. When the movable guide plate 110 needs to be retracted, the material can unfold and expand again, thereby enveloping and collecting more dirt into the water surface intake 111.

[0080] The movement of the movable guide plate 110 includes, for example, rotation.

[0081] As shown in Figures 1 and 2, the movement of the movable guide plate 110 may include, for example, rotation about a first end of the movable guide plate 110, which is the connection end between the movable guide plate 110 and the housing 100, and the first end may include a pivot or a rotating shaft.

[0082] The controller can move the movable guide plate 110 corresponding to the detected direction of the obstacle to the third position.

[0083] During the cleaning process, the automatic pool cleaning device 10 can detect the direction of obstacles in the pool using sensors (e.g., image sensors). The controller then controls the movable guide plate 110 corresponding to that direction to move from a first position to a third position. For example, as shown in Figure 7, if the automatic pool cleaning device 10 detects an obstacle on the left side of its path during cleaning, the controller can move the movable guide plate 113 on the left side from the first position to the third position. That is, the movable guide plate 113 is retracted inwards to avoid collision with the obstacle.

[0084] The automatic water tank cleaning device 10 may further include a sensor, wherein when the sensor detects an object to be cleaned on the water surface, the drive device 210 controls the movable guide plate 110 to move to a second position and then to a first position, so that the object to be cleaned is pushed by the movable guide plate 110 and enters the water surface suction port 111.

[0085] The sensor may be an image sensor, an ultrasonic sensor, a laser sensor, or any other sensor that can implement the technical principles of this application.

[0086] When the sensor detects an object to be cleaned (such as twigs, leaves, or paper scraps) on the water surface, the movable guide plate 110 can move from a first position (i.e., open state) to a second position (i.e., closed state), thereby guiding the object to be cleaned into the water surface suction port 111 for filtration. After the object enters the water surface suction port 111, the automatic pool cleaning device 10 still needs to continue cleaning. Therefore, the movable guide plate 110 needs to be moved from the second position to the first position, thus setting the movable guide plate 110 to the open state, allowing dirt on the water surface to enter the water surface suction port 111. Thus, by switching between the opening and closing of the movable guide plate 110, the cleaning operation can be performed more efficiently than relying solely on water flow to carry dirt into the water surface suction port 111.

[0087] Of course, during the process of the movable guide plate 110 guiding the object to be cleaned into the water surface suction port 111 on the water surface, it is not necessary to move the movable guide plate 110 from the second position to the first position. A suitable range of movement can be selected between the second position and the first position as the range of movement. The main purpose is to guide the object to be cleaned into the water surface suction port 111 for filtration by moving the movable guide plate 110.

[0088] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate.
