[0002] With the increasing popularity of swimming pools, cleaning them has become a crucial part of their daily use and maintenance. Currently, automatic pool cleaning systems typically include filters that remove sand, weeds, and other impurities through suction. For example, when cleaning the pool bottom or surface, the automatic cleaning system collects impurities in the filter and discharges the filtered water back into the pool. Typically, the filter is detachably installed on the automatic cleaning system. Therefore, how to detachably install and securely fix the filter to the automatic pool cleaning system has become a pressing technical challenge. Summary of the Invention

Detailed Implementation

[0020] 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.

[0021] This application provides an automatic pool cleaning device. The automatic pool cleaning device of this application can be a device such as a cleaning robot, 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 storage tank, a water storage trough, etc. This application does not limit the specific presentation of the automatic pool cleaning device or the pool-shaped structure, as long as it achieves the principles of this application. 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.

[0022] For example, when cleaning a pool, the robot can include multiple cleaning modes, such as a pool bottom cleaning mode, a pool wall cleaning mode, and a water surface cleaning mode. The pool bottom cleaning mode can include a pool bottom edge cleaning mode and a pool bottom surface cleaning mode; the water surface cleaning mode can include a water surface edge cleaning mode and a random water surface cleaning mode. In the pool wall cleaning mode, the robot attaches to the sidewall using the suction principle of a water pump.

[0023] For example, the robot is detachably equipped with a filter. During the cleaning operation, the filter is used to filter impurities from the collected water, and the robot collects these impurities (such as sand, algae, dust, etc.) into the filter. After the cleaning operation is completed, the filter can be removed from the robot by the user to clean the remaining impurities or replace the filter. In the art, the filter may also be referred to as a "dust box," "trash basket," etc. During the installation of the filter onto the robot, improper installation may occur. In one example, improper installation may be caused by the rotation of gears on the filter and / or the main body during installation, resulting in filter misalignment.

[0024] The automatic water tank cleaning device of this application will be described below with reference to the accompanying drawings. Figure 1 The structure of the automatic water tank cleaning device provided in this application is shown, such as... Figure 1 As shown, the automatic water tank cleaning device provided in this application includes a filter 1 and a main body 2; the filter 1 is installed on the main body 2.

[0025] It is understood that the filter 1 can be a cylindrical container with a cavity. The cavity is used to temporarily store impurities collected by the filter 1. The cross-section of the filter 1 can be circular or square. The filter assembly of the filter 1 can be one or more combinations of filter screen, filter element, and filter membrane.

[0026] It is worth noting that different water bodies may present different filtration needs. For example, if the water body contains a large proportion of millimeter-sized impurities such as fallen leaves, twigs, and insects, a filter screen can be used as the main filtration component. Conversely, if the water body contains a large proportion of hundred-micron-sized impurities such as sand, algae, and suspended solids, a filter cartridge with a precision greater than 50 μm can be used as the main filtration component. The above description of the filter 1 is merely exemplary, and the filter 1 protected by this application is not limited to the contents listed above. Those skilled in the art can select the type and model of the filter 1 according to the actual situation, as long as it can achieve the technical principles of this application.

[0027] Figure 2 A schematic diagram of the structure of the first fixing component of this application is shown. Figure 2 The diagram also shows a portion of the structure of the filter 1. Figure 3 A schematic diagram of the structure of the second fixing component of this application is shown. Figure 3 The diagram also shows a portion of the structure of the main body 2. The filter 1 is provided with a first fixing component. The main body 2 is provided with a second fixing component. Under external force, the first fixing component switches between a first state and a second state; in the first state, the first fixing component enters or disengages from the second fixing component; in the second state, the first fixing component interlocks with the second fixing component, thereby fixing the filter 1 to the main body 2. The filter 1 and the main body 2 will be described in detail below with reference to specific embodiments.

[0028] like Figure 2 As shown, the filter 1 is provided with a first fixing component. Figure 3 As shown, a second fixing component is provided on the main body 2.

[0029] It is understood that the aforementioned configuration can be fixed, detachable, or integrally formed. For example, the first fixing component can be riveted or hinged to the filter 1. Alternatively, the first fixing component can be installed on the filter 1 via a snap-fit. Yet another example is that the first fixing component can also be integrally formed with the filter 1. The configuration of the second fixing component on the main body 2 is similar and will not be elaborated upon here.

[0030] Under the action of external force, the first fixing component switches between a first state and a second state; in the first state, the first fixing component enters or disengages from the second fixing component; in the second state, the first fixing component and the second fixing component interlock, thereby fixing the filter 1 to the body 2. The first fixing component and the second fixing component will be described in detail below with reference to specific examples.

[0031] It is understood that the external force can act directly on the first fixing component. In one scenario, the first fixing component can be connected to the handle 3, so the external force can first act on the handle 3, and then the handle 3 transmits the external force to the first fixing component, thereby allowing the external force to act indirectly on the first fixing component through the handle 3. During the installation of the filter 1 onto the body 2, the first fixing component enters the second fixing component. During the removal of the filter 1 from the body 2, the first fixing component disengages from the second fixing component. In the interlocked state between the first fixing component and the second fixing component, the relative movement of the filter 1 and the body 2 is restricted, thereby fixing the filter 1 to the body 2.

[0032] The following is combined with Figure 2 and Figure 3 The example shown provides a specific illustration of the first fixing component. The first fixing component includes a rotating member 11 and a limiting member 12, the limiting member 12 being located on one side of the rotating member 11, wherein, in a first state, the rotating member 11 is away from the limiting member 12, and in a second state, the rotating member 11 abuts against the limiting member 12.

[0033] It is understood that the rotating member 11 is a component capable of relative movement with the limiting member 12. Figure 2 The rotating member 11 shown in the exemplary illustration is circular. It is understood that the rotating member 11 includes, but is not limited to, circular, elliptical, or other regular or irregular shapes. One side of the rotating member 11 can be one side of the tangent line at any point on the rotation trajectory of the rotating member 11. For example, as... Figure 2 As shown, when the axis of rotation of the rotating member 11 is horizontal, the rotating member 11 can be the upper side, lower side, left side or right side of the rotating member 11.

[0034] It is worth noting that when the rotating member 11 rotates, its relative position to the limiting member 12 can change, thereby enabling the first fixing component to switch between the first state and the second state. When the rotating member 11 moves away from the limiting member 12, the limiting member 12 does not restrict the rotation of the rotating member 11, allowing the rotating member 11 to reach the unlocked position. In the unlocked position, the first fixing component can enter the second fixing component, or the first fixing component can disengage from the second fixing component. The unlocked position can be one or more. In the second state, the rotating member 11 abuts against the limiting member 12, causing the limiting member 12 to restrict the rotation of the rotating member 11. Therefore, the rotating member 11 is restricted to the interlocked position and cannot reach the unlocked position. In the interlocked position, the relative movement of the first fixing component and the second fixing component is restricted and thus relatively fixed, thereby achieving interlocking between the first fixing component and the second fixing component.

[0035] like Figure 2 As shown, the rotating member 11 includes a first protrusion structure 111, wherein, in the first state, the first protrusion structure 111 is away from the limiting member 12, and in the second state, the first protrusion structure 111 abuts against the limiting member 12.

[0036] It is understood that the first protrusion 111 may be disposed on the edge of the rotating member 11. The first protrusion 111 may be a cylinder or other columnar body. At least a portion of the first protrusion 111 protrudes outward from the rotating member 11, and during the rotation of the rotating member 11, the first protrusion 111 can rotate accordingly, such that at a certain moment or in a certain state, the first protrusion 111 abuts against the limiting member 12. For example, in a second state, the limiting member 12 restricts the rotating member 11 by abutting against the first protrusion 111.

[0037] In the first state, the first protrusion structure 111 can rotate along the first direction and pass one end of the limiting member 12 under the action of external force, so as to switch to the second state.

[0038] It is understood that the first direction can be clockwise or counterclockwise. The external force is a force directly or indirectly from the user (e.g., the force from the user's hand when turning the rotating component 11).

[0039] In one example, the first protrusion 111 may be made of an elastic material such as rubber or elastic plastic. Under the action of the external force, the first protrusion 111 is capable of rotating in a first direction. When the first protrusion 111 rotates to contact one end of the limiting member 12 and the external force is not less than a first threshold, the first protrusion 111 undergoes elastic deformation, thereby passing over the limiting member 12 and continuing to rotate in the first direction. After passing over the limiting member 12, the first protrusion 111 can abut against the limiting member 12.

[0040] It is worth noting that the first threshold is the minimum force required to deform the first protrusion 111 beyond one end of the limiting member 12. The first threshold should be greater than the external force generated by the rotation of the gears on the filter 1 and / or the body 2 during installation to prevent the gear rotation from causing the interlock to disengage.

[0041] The rotating component 11 also includes a first groove 113, which is disposed on one or both sides of the protruding structure.

[0042] Understandably, the depth of the first groove 113 can adjust the first threshold. For example, the greater the depth of the first groove 113, the smaller the first threshold.

[0043] It is worth noting that the smaller the first threshold, the smaller the external force required for the first protrusion structure 111 to pass over the limiting member 12. Those skilled in the art can design the depth of the first groove 113 based on the correspondence between the first threshold and the depth of the first groove 113, thereby obtaining the required first threshold.

[0044] The following is combined with Figure 2 and Figure 3 The interaction between the rotating component 11 and the second fixed component will be explained.

[0045] like Figure 2 As shown, the rotating member 11 also includes a second protrusion structure 112, which is disposed on the surface of the rotating member 11 near the second fixing component.

[0046] It is understood that the second protrusion structure 112 can be a cylinder or other columnar body. The end of the second protrusion structure 112 can be configured as a hemispherical surface, an arc surface, or a cylindrical surface.

[0047] It is worth noting that the second protruding structure 112 is eccentrically positioned relative to the rotating member 11. When the rotating member 11 rotates, the second protruding structure 112 changes position relative to the second fixing component on the main body 2.

[0048] like Figure 3As shown, the second fixing component includes a limiting channel 21 and a receiving cavity 22; in the first state, the second protrusion structure 112 enters or disengages from the limiting channel 21; in the second state, the second protrusion structure 112 rotates within the receiving cavity 22 and abuts against one side wall of the receiving cavity 22.

[0049] It is understood that the limiting channel 21 can be groove-shaped or strip-shaped. The limiting channel 21 can be a straight channel or an arc-shaped channel. The shape of the edge of the receiving cavity 22 can match the shape of the rotation trajectory of the second protrusion structure 112 within the receiving cavity 22.

[0050] The interaction between the first and second fixing components is achieved through the second protruding structure 112. When the rotation reaches the unlocked position described above, the second protruding structure 112 can enter or exit the receiving cavity 22 along the limiting channel 21. The rotation of the rotating member 11 can cause the second protruding structure 112 to change position within the receiving cavity 22. When the first protruding structure 111 passes one end of the limiting member 12 and abuts against the limiting member 12 as the rotating member 11 rotates, the second protruding structure 112 abuts against one side wall of the receiving cavity 22. In the absence of external force or when the external force does not reach the first threshold, the first protruding structure 111 is locked by the limiting member 12, thereby locking the second protruding structure 112 within the receiving cavity 22.

[0051] In one example, the entrance to the limiting channel 21 is funnel-shaped.

[0052] It is understood that the flared shape is a shape that narrows inward from the opening. When the second protruding structure 112 enters the limiting channel 21, the flared entrance can guide the second protruding structure 112 to enter along the edge of the flared shape.

[0053] like Figure 2 As shown, the filter 1 also includes a handle 3, which is coaxially arranged with the rotating component 11.

[0054] It is understood that the handle 3 can be a door-shaped handle or an arched handle. The coaxial arrangement means that the rotation axis of the handle 3 is coaxial with the rotation axis of the rotating component 11.

[0055] In one example, under the action of the external force, the handle 3 drives the rotating member 11 to switch between the first state and the second state; wherein, in the first state, the handle 3 may protrude from the upper surface of the filter 1, for example, and in the second state, the handle 3 may be lower than the upper surface of the filter 1 or flush with the upper surface of the filter 1, for example.

[0056] It is understood that the handle 3 can rotate around the pivot under the action of an external force. When the handle 3 rotates, the rotating component 11 is driven to rotate by the handle 3, thereby switching between the first state and the second state.

[0057] The handle 3 protruding from the upper surface of the filter 1 means that at least a portion of the handle 3 protrudes from the upper surface of the filter 1. The protruding portion of the handle 3 enables a lifting action on the filter 1, facilitating the smooth movement of the second protruding structure 112 within the limiting channel 21 during disassembly or installation.

[0058] In the second state, the first and second fixing components interlock, and the filter 1 is installed in place, eliminating the need to lift the filter 1. When the handle 3 is lower than or flush with the upper surface of the filter 1, the handle 3 no longer protrudes from the upper surface of the filter 1, preventing debris from getting caught on the handle 3.

[0059] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate.
