[0031] Embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. In the drawings, identical or equivalent parts are given the same reference numerals, and their descriptions are not repeated.

[0032] Automatic pool cleaning devices need to monitor their own posture or status during cleaning operations in water in order to perform operations such as extrication or shutdown when it is determined that they are in a state such as being stranded or out of water.

[0033] Figure 1 and Figure 2 An example of a water-free detection mechanism 100 for use in an automatic pool cleaning device is shown. The water-free detection mechanism 100 includes a rotatable part 110 and a detection part 120 located near the rotatable part 110, wherein the detection part 120 is configured to detect rotation of the rotatable part 110 in order to determine the water-free state of the automatic pool cleaning device.

[0034] Using the water-free detection mechanism 100, it is possible to determine whether at least the part of the automatic pool cleaning device equipped with the water-free detection mechanism 100 is currently out of water, and thus determine whether at least a part of the automatic pool cleaning device is currently in a state such as stranded or out of water, thereby allowing corresponding operations to be performed based on the judgment result, such as continuing operation, entering the escape mode, or shutting down.

[0035] like Figure 1 and Figure 2 As shown, the rotatable component 110 can be configured as a frame structure that can rotate on one side, having a first end 111 and a second end 112, wherein the first end 111 is a fixed end or mounting end that can be connected to or installed on an automatic water tank cleaning device, and the second end 112 is a rotating end or free end that can rotate relative to the first end 111.

[0036] For example, the first end 111 of the rotatable component 110 can be connected to or mounted on the automatic pool cleaning device using any suitable hinge structure, such as a single hinge or a double hinge, so that the rotatable component 110, or in other words, the second end 112 of the rotatable component 110, can rotate about the rotation axis, i.e., the hinge axis 113 in the hinge structure. For example, the rotatable component 110 can be configured such that the center of mass of the rotatable component 110 is offset from the hinge axis 113 of the rotatable component 110.

[0037] The rotatable component 110 can be configured such that when the rotatable component 110 is in water, the upward buoyancy force on the rotatable component 110 in the water is sufficient to overcome the weight of the rotatable component 110 itself, so that the rotatable component 110 can rotate under the action of the upward buoyancy force in the water, for example, it can rotate at least a threshold angle (e.g., 15 degrees or 20 degrees, etc.).

[0038] For example, the rotatable component 110 may be configured using a lightweight material with a density lower than that of water, such as foam or lightweight plastic, and / or may be configured in any shape and / or volume suitable for or readily buoyant in water. For example, the rotatable component 110 may be configured as an airtight structure.

[0039] Additionally, for example, components such as buoyancy blocks can be disposed on the rotatable component 110 to increase buoyancy in water and / or reduce the overall average density of the rotatable component 110. The buoyancy blocks can be implemented using any suitable one or more materials or structures, such as foam or airtight structures, and at least a portion of the buoyancy blocks can be disposed inside and / or outside the rotatable component 110. By configuring buoyancy blocks, it becomes possible to implement the rotatable component 110 using a wider range of materials and / or structures.

[0040] When the rotatable part 110 is not in water, such as Figure 1As shown, the rotatable component 110 can, for example, be in a first state under the action of its own gravity G.

[0041] When the rotatable component 110 is submerged in water, it can overcome the influence of its own weight G under the action of an upward buoyancy force F in the water, and start from the previous first state, for example, according to... Figure 2 The solid arrow A1 in the diagram indicates a rotation around hinge axis 113 exceeding the aforementioned threshold angle, and thus becomes... Figure 2 The second state is shown.

[0042] When the rotatable component 110 leaves the water again, the buoyancy force F acting on it in the water decreases and disappears when it is completely out of the water. During this process, the rotatable component 110, at least under its own weight G, returns to its previous second state, for example, according to... Figure 2 The solid arrow A2 in the diagram indicates the direction of rotation around hinge 113, and eventually returns to its original position. Figure 1 The first state is shown.

[0043] In some embodiments, the rotatable component 110 may be configured with a non-uniform density structure. For example, the density or weight of the portion of the rotatable component 110 near the second end 112 may be greater than the density or weight of the portion of the rotatable component 110 near the first end 111, or a counterweight may be provided at the second end 112, so that the rotatable component 110 can more smoothly return from the second state to the first state when it is removed from the water.

[0044] In addition, such as Figure 2 As shown, a limiting structure 130 can also be provided, and the first end 111 of the rotatable component 110 can be connected to or mounted on the limiting structure 130, thereby limiting the rotation amplitude of the rotatable component 110 (or, in other words, the second end 112 of the rotatable component 110), for example, controlling the rotatable component 110 (or, in other words, the second end 112 of the rotatable component 110) to rotate to one side, and the maximum angle of rotation does not exceed another threshold angle (e.g., 80 degrees or 90 degrees). Thus, it is possible to prevent the rotatable component 110 from rotating excessively under the action of buoyancy F and failing to smoothly return from the second state to the first state.

[0045] The limiting structure 130 can be configured to any suitable shape or structure, provided that the rotation amplitude and / or rotation direction of the rotatable member 110 (or, the second end 112 of the rotatable member 110) can be limited.

[0046] The limiting structure 130 may be part of the rotatable component 110, for example, as part of the first end 111 of the rotatable component 110, or it may be independent of the rotatable component 110 and configured as a component of the automatic pool cleaning device, or it may be integrally formed, for example, with part of the housing of the automatic pool cleaning device or part of a support structure of the automatic pool cleaning device.

[0047] The limiting structure 130 can be installed in any suitable location on the automatic pool cleaning device by any suitable means. For example, the limiting structure 130 can be detachably installed on the housing (e.g., the inner or outer wall of the housing) or a frame or support structure (e.g., a support plate) inside the automatic pool cleaning device by any suitable means such as snap-fit ​​connection or screw fixing, or it can be fixed to the housing (e.g., the inner or outer wall of the housing) or a frame or support structure (e.g., a support plate) inside the automatic pool cleaning device by any suitable means such as adhesive or integral molding.

[0048] At least a portion of the aforementioned hinge structure (e.g., the hinge seat portion) can be mounted on or as part of the limiting structure 130 by any suitable means. For example, at least a portion of the hinge structure (e.g., the hinge seat portion) can be detachably mounted on the limiting structure 130 by any suitable means such as snap-fit ​​connection or screw fixing, and can also be fixed on the limiting structure 130 by any suitable means such as adhesive or integral molding.

[0049] like Figure 1 and Figure 2 As shown, the detection component 120 can be configured near the rotatable component 110 and can be configured to detect the rotation of the rotatable component 110, such as including but not limited to detecting changes in the position, angle and / or distance of the second end 112 of the rotatable component 110 relative to the detection component 120, so as to further determine whether the rotatable component 110 or the water separation detection mechanism 100 is currently separated from the water.

[0050] For example, the detection component 120 may include a Hall sensor, and correspondingly, the rotatable component 110 may include any object, structure, and / or component, such as a magnet, that can be sensed by the Hall sensor for changes in position, angle, and / or distance. Such an object, structure, or component may be configured or mounted on the rotatable component 110 by any suitable means such as embedding, attaching, or coating. For example, an object, structure, and / or component, such as a magnetic block or magnetic sheet, that can be sensed by the Hall sensor for changes in position, angle, and / or distance may be configured or mounted at the second end 112 of the rotatable component 110 by suitable means such as embedding, attaching, or coating.

[0051] As described above, the rotatable component 110 can rotate under the influence of buoyancy F or its own weight G in the water. When the rotation of the rotatable component 110 brings the second end 112 closer to the Hall sensor of the detection component 120 (e.g., into the sensing range of the Hall sensor), the intervention switch of the Hall sensor can be turned on. Conversely, when the rotation of the rotatable component 110 moves the second end 112 away from the Hall sensor of the detection component 120 (e.g., out of the sensing range of the Hall sensor), the intervention switch of the Hall sensor can be turned off. Thus, the detection component 120 can determine the state of the rotatable component 110, and thereby determine whether the water-out detection mechanism 100 is currently in the water.

[0052] In different embodiments, the detection component 120 can be configured at any suitable location near the rotatable component 110.

[0053] For example, such as Figure 1 and Figure 2 As shown, the detection component 120 can be configured below the second end 113 of the rotatable component 110.

[0054] In such a situation, when the water detection device 100 is not in water, such as Figure 1 As shown, the rotatable component 110 can be in a first state under its own weight G, and the second end 112 of the rotatable component 110 is close to the detection component 120. At this time, the intervention switch of the Hall sensor of the detection component 120 is turned on, thereby determining that the water-free detection mechanism 100 is currently in a water-free state.

[0055] When the water detection unit 100 is in water, such as Figure 2 As shown, the rotatable component 110 can, for example, be in a second state under the influence of buoyancy F in the water, and the second end 112 of the rotatable component 110 is away from the detection component 120. At this time, the intervention switch of the Hall sensor of the detection component 120 is disconnected, thereby determining that the water separation detection mechanism 100 is currently in the water.

[0056] When the water separation detection mechanism 100 leaves the water again, the buoyancy force F on the rotatable component 110 decreases and disappears when the water separation detection mechanism 100 is completely out of the water. During this process, the rotatable component 110, at least under the action of its own weight G, returns to its original position. Figure 1 The first state is shown. At this time, the intervention switch of the Hall sensor of the detection component 120 is turned on again, thereby confirming that the water separation detection mechanism 100 is currently in the water separation state.

[0057] In other examples, such as Figure 3 and Figure 4As shown, the detection component 120 can be configured on the side of the second end 113 of the rotatable component 110.

[0058] In such a situation, when the water detection device 100 is not in water, such as Figure 3 As shown, the rotatable component 110 can be in a first state under its own weight G, and the second end 112 of the rotatable component 110 is away from the detection component 120. At this time, the intervention switch of the Hall sensor of the detection component 120 is turned off, thereby determining that the water-free detection mechanism 100 is currently in a water-free state.

[0059] When the water detection unit 100 is in water, such as Figure 4 As shown, the rotatable component 110 can, for example, be in a second state under the action of buoyancy F in the water, and the second end 112 of the rotatable component 110 is close to the detection component 120. At this time, the intervention switch of the Hall sensor of the detection component 120 is turned on, thereby determining that the water separation detection mechanism 100 is currently in the water.

[0060] When the water separation detection mechanism 100 leaves the water again, the buoyancy force F on the rotatable component 110 decreases and disappears when the water separation detection mechanism 100 is completely out of the water. During this process, the rotatable component 110, at least under the action of its own weight G, returns to its original position. Figure 3 The first state is shown. At this time, the intervention switch of the Hall sensor of the detection component 120 is disconnected again, thereby confirming that the water separation detection mechanism 100 is currently in the water separation state.

[0061] In another embodiment, the detection component 120 may also be configured above the second end 113 of the rotatable component 110 or at any other suitable location.

[0062] The shape and / or structure of the rotatable component 110, the position of the first end 111 and / or the second end 112 of the rotatable component 110 on the rotatable component 110, the relative positional relationship between the first end 111 and the second end 112, the mounting structure and / or mounting method of the first end 111, the shape and / or structure of the hinge structure, the shape and / or structure of the limiting structure 130, the connection method between the rotatable component 110 and the limiting structure 130, the initial posture of the rotatable component 110 after being connected to the limiting structure 130, the relative positional relationship between the rotatable component 110 and the detection component 120, the shape and / or structure of the detection component 120, etc. are not limited to the above examples, but can have a variety of variations while conforming to the above principles.

[0063] Figures 5 to 7 Another example of a water separation detection device 100 is shown.

[0064] In this example, the first end 111 of the rotatable component 110 is configured as at least one rotating arm, with a protrusion at one end of each rotating arm that can serve as a hinge pin 113. The second end 112 of the rotatable component 110 is configured as a small first frame in which a magnet block capable of serving as a sensing target for the detection component 120 can be embedded or accommodated.

[0065] The rotatable component 110 also includes a larger second frame connecting the first end 111 and the second end 112. This second frame can be configured, for example, using a lightweight material with a density lower than that of water, such as foam or lightweight plastic, and / or can be configured as an airtight structure, or embedded in or accommodating a buoyancy block. The other end of each rotating arm of the first end 111, opposite the protrusion, is fixed to one side of the second frame. Alternatively, the second frame can also be configured on the rotating arm.

[0066] In this example, such as Figures 5 to 7 As shown, the limiting structure 130 includes a side plate portion 131 and a hinge portion 132 of a hinge structure.

[0067] The hinge portion 132 may be integrally formed with the side plate portion 131, or it may be mounted or fixed to the side plate portion 131 by any suitable means, for example, it may be configured on the upper part of the side plate portion 131. A through hole is provided on the hinge portion 132 that matches the hinge pin 113 on the first end 111 of the rotatable member 110. The hinge pin 113 on the first end 111 of the rotatable member 110 is inserted into the through hole and can rotate within the through hole, thereby forming a hinge structure.

[0068] In this example, the rotatable member 110 is configured such that the main body portion of each rotating arm, which serves as the first end 111 (possibly along with at least a portion of the rotatable member 110), is located below the hinge pin 113 when the rotatable member 110 is in the first state. In another example, for example... Figure 8 and Figure 9 As shown, the rotatable component 110 is also configured such that the main body portion of each rotating arm, which is the first end 111 (possibly along with at least a portion of the rotatable component 110), is positioned above the hinge pin 113 when the rotatable component 110 is in the first state, for example, or may be in any other suitable configuration.

[0069] The side plate portion 131 may extend downward in a vertical plane such that at least a portion of each rotating arm, which is the first end 111, is located on one side of the side plate portion 131, and can only be positioned, for example, according to Figure 6 As indicated by the arrow, the rotatable member 110 can rotate on one side of the side plate portion 131 but not on the other side, thus limiting the rotation range of the rotatable member 110.

[0070] In addition, such as Figure 5 and Figure 7 As shown, a limiting protrusion 133 may be provided on a portion of the edge of the hinge portion 132. When each rotating arm, which is the first end 111, rotates away from the side plate portion 131 on one side, it will eventually be blocked by the limiting protrusion 133 and will not be able to continue rotating away from the side plate portion 131, thereby limiting the upper limit of the rotation amplitude of the rotatable member 110.

[0071] Each rotating arm, serving as the first end 111, can be configured into any suitable shape, such as a roughly triangular shape, thereby defining an upper limit of the rotation amplitude in conjunction with the limiting protrusion 133. For example, the upper limit of the rotation amplitude can be any suitable value within the range of 20 degrees to 80 degrees, or it can be a value greater than 80 degrees and less than 90 degrees.

[0072] like Figures 5 to 7 As shown, at least a portion of the detection component 120 can also be mounted or fixed to the side plate portion 131.

[0073] Additionally, depending on the location and space for installing the water separation detection mechanism 100 in the automatic water cleaning device, for example, when the automatic water cleaning device is normally placed horizontally, the projections of the rotatable component 110 and the detection component 120 on at least one of the horizontal and vertical planes may overlap or not overlap, and / or the appearance of at least one of the rotatable component 110 and the detection component 120 may be symmetrical or asymmetrical.

[0074] For example, such as Figures 5 to 7 As shown, the projections of the rotatable component 110 and the detection component 120 in the horizontal and vertical planes do not overlap. The first frame can be disposed on one side of the second frame and biased towards one side of the second frame, and at least one side of the first frame faces a portion of the detection component 120.

[0075] Figure 8 and Figure 9 Another example of a rotatable component 110 of a water separation detection mechanism 100 is shown. In this example, the rotatable component 110 further includes an extension arm 140 that connects directly or indirectly to the first end 111 and the second end 112. The extension arm 140 may, for example, be configured in a curved shape. By configuring the extension arm 140, the detection component 120 can be positioned at a location relatively far from the second end 112 of the rotatable component 110.

[0076] It should be understood that the configuration of the water separation detection mechanism 100 disclosed herein (including but not limited to the shape and / or structure of the rotatable component 110, the position of the first end 111 and / or the second end 112 of the rotatable component 110 on the rotatable component 110, the relative positional relationship between the first end 111 and the second end 112, the mounting structure and / or mounting method of the first end 111, the shape and / or structure of the hinge structure, the shape and / or structure of the limiting structure 130, the connection method between the rotatable component 110 and the limiting structure 130, the initial posture of the rotatable component 110 after being connected to the limiting structure 130, the relative positional relationship between the rotatable component 110 and the detection component 120, the shape and / or structure of the detection component 120, etc.) is not limited to the above examples, but can have various variations while conforming to the above principles.

[0077] As needed, any suitable number of water separation detection units 100 can be installed at any one or more suitable locations on the automatic pool cleaning device, including both the exterior and interior of the automatic pool cleaning device housing.

[0078] For example, the rotatable part 110 and the detection part 120 of the water separation detection mechanism 100 can both be installed inside the housing of the automatic water tank cleaning device. Alternatively, the rotatable part 110 can be installed inside the housing of the automatic water tank cleaning device and the detection part 120 can be installed outside the housing of the automatic water tank cleaning device. Alternatively, the rotatable part 110 can be installed outside the housing of the automatic water tank cleaning device and the detection part 120 can be installed inside the housing of the automatic water tank cleaning device. Alternatively, at least a portion of at least one of the rotatable part 110 and the detection part 120 of the water separation detection mechanism 100 can be installed inside the housing of the automatic water tank cleaning device and another portion of at least one of the rotatable part 110 and the detection part 120 of the water separation detection mechanism 100 can be installed outside the housing of the automatic water tank cleaning device.

[0079] Figure 10 An example of an automatic water tank cleaning device 200 equipped with a water separation detection mechanism 100 is shown.

[0080] like Figure 10As shown, the automatic water cleaning device 200 may include an inlet 210, a filter mechanism 220 (e.g., a trash can, a filter screen, etc.), and an outlet 230. The inlet 210, the filter mechanism 220, and the outlet 230 are connected in sequence, so that water from outside the automatic water cleaning device 200 can enter the automatic water cleaning device 200 from the inlet 210 under the action of a mechanism / component (not shown in the figure) such as a water pump inside the automatic water cleaning device 200, and after being filtered by the filter mechanism 220, it is discharged to the outside of the automatic water cleaning device 200 through the outlet 230, thereby forming a water flow channel 240 in the automatic water cleaning device 200.

[0081] like Figure 10 As shown, at least a portion of the rotatable component 110 of the water separation detection mechanism 100 can be disposed on the water flow channel in the automatic pool cleaning device 200 or disposed in a chamber 250 at the rear of the automatic pool cleaning device that is open to external communication, and / or at least a portion of the detection component 120 can be disposed in a sealed cavity 260 in the automatic pool cleaning device. For example, the first end 111 of the rotatable component 110 can be mounted at the rear of the automatic pool cleaning device 200.

[0082] In this example, when the rear of the automatic pool cleaning device 200 is submerged in water, the rotatable component 110 of the water separation detection mechanism 100 can rotate eccentrically under the upward buoyancy force in the water, moving away from or closer to the detection component 120, and becoming, for example... Figure 2 or Figure 4 In the second state shown, when the rear of the automatic water cleaning device 200 is removed from the water, the rotatable component 110 of the water removal detection mechanism 100 can rotate eccentrically under its own gravity, moving closer to or away from the detection component 120, and becoming, for example... Figure 1 or Figure 3 The first state is shown in the figure.

[0083] As mentioned above, the detection component 120, which is located near the rotatable component 110, can detect the rotation of the rotatable component 110. For example, it can detect changes in the position, angle, and / or distance of the second end 112 of the rotatable component 110 relative to the detection component 120, and thus determine whether the rear of the automatic cleaning device 200 of the pool is currently out of the water based on the detection result of the detection component 120.

[0084] like Figure 11 As shown, in Figure 10 Based on the example or alternatively, a water separation detection mechanism 100 may be configured in a chamber 270 at the front of the automatic pool cleaning device and open to the outside. For example, the first end 111 of the rotatable component 110 may be mounted at the front of the automatic pool cleaning device 200.

[0085] In this example, when the front of the automatic pool cleaning device 200 is submerged in water, the rotatable component 110 of the water separation detection mechanism 100 can rotate eccentrically under the upward buoyancy force in the water, moving away from or closer to the detection component 120, and becoming, for example... Figure 2 or Figure 4 In the second state shown, when the rear of the automatic water cleaning device 200 is removed from the water, the rotatable component 110 of the water removal detection mechanism 100 can rotate eccentrically under its own gravity, moving closer to or away from the detection component 120, and becoming, for example... Figure 1 or Figure 3 The first state is shown in the figure.

[0086] As mentioned above, the detection component 120, which is located near the rotatable component 110, can detect the rotation of the rotatable component 110. For example, it can detect changes in the position, angle, and / or distance of the second end 112 of the rotatable component 110 relative to the detection component 120, and thus determine whether the front of the automatic pool cleaning device 200 is currently out of the water based on the detection result of the detection component 120.

[0087] like Figure 12 The automatic water tank cleaning device 200 may also include a controller 280.

[0088] The controller 280 may include any circuitry and / or module with data processing and / or instruction execution capabilities, such as a central processing unit (CPU), a graphics processing unit (GPU), or a field-programmable gate array (FPGA), and is suitable for the automatic pool cleaning device 200. It may be configured, for example, to perform data processing and / or control related to the cleaning operations and / or other functions of the automatic pool cleaning device 200, based on programs stored in a memory (not shown) within the automatic pool cleaning device 200 and / or instructions from a control panel (not shown) or control terminal (not shown) of the automatic pool cleaning device 200.

[0089] For example, the controller 280 can determine the current state of the automatic pool cleaning device 200 based on the detection data from at least one water-free detection mechanism 100 configured at the front and / or rear of the automatic pool cleaning device 200. For example, it can determine whether only the head or only the tail of the automatic pool cleaning device 200 is out of the water, or whether the entire device is out of the water or the entire device is still in the water. In this way, it can determine whether the automatic pool cleaning device 200 is in a normal working posture or state, or whether it is in an abnormal working posture or state such as being stranded.

[0090] Furthermore, the controller 280 can control the subsequent operations of the automatic pool cleaning device 200 based on the judgment result. For example, if the controller 280 determines that the front and / or rear of the automatic pool cleaning device 200 is out of water, the controller 280 can control the automatic pool cleaning device 200 to enter the escape mode or shut down.
