[0021] Furthermore, dimensions may be exaggerated in the accompanying drawings for clarity and are not drawn to scale. Throughout the drawings, the same reference numerals generally refer to the same elements.

[0022] Figure 1 The diagram schematically illustrates the external shape of an automatic pool cleaning device 10 according to an embodiment of the present disclosure. It can perform cleaning operations on the bottom, walls, water, and surface of a pool (e.g., a swimming pool) as needed, for example, to remove debris from the water, bottom, and surface, and to clean dirt from the pool bottom and walls. Figure 1 As shown, the automatic pool cleaning device 10 may include a housing 110, a traveling mechanism 120, a cleaning mechanism 130, and other structures / components. As an example, the automatic pool cleaning device 10 may also include a buoyancy adjustment mechanism, allowing the device to adjust its depth in the water as needed; for example, it can float on the surface, submerge, or sink to the bottom for cleaning operations on the surface, in the water, or at the bottom. As an example, control circuits such as a control unit and an inertial measurement unit (IMU) may be installed inside the housing 10. A drive mechanism such as a water pump and a drive motor may be provided, and a filtration mechanism, such as a dust box, may also be included to filter and purify the water entering the dust box through the inlet, removing impurities, and then discharging the cleaned water from the automatic pool cleaning device through the outlet. As an example, Figure 1 The diagram shows that the traveling mechanism 120 may include tracked traveling mechanisms on both sides of the lower part of the automatic pool cleaning device 10, allowing the pool cleaning device to travel in water, at the bottom of the pool, or on the pool wall to perform corresponding cleaning operations. However, the traveling mechanism is not limited to... Figure 1 The type shown can include, for example, a wheeled traveling mechanism, without limitation. As an example, the traveling mechanism can also include, for instance, a water spray mechanism, so that when the automatic pool cleaning device 10 travels along the pool wall, it can use the pressure generated by the sprayed water to adhere to the pool wall and maintain stability; or it can use the thrust generated by the sprayed water to travel on the water surface. Figure 1 As shown, the cleaning mechanism 130 may include components such as roller brushes on the front and / or rear sides of the automatic pool cleaning device.

[0023] According to one or more embodiments, the automatic pool cleaning device 10 can be configured to drive the traveling mechanism 120 in a specified mode under the control of an internal control unit, so that the automatic pool cleaning device 10 moves along a specific trajectory or toward a specific direction on the bottom, walls, water, and surface of the pool; at the same time, the cleaning mechanism 130 can be activated to clean up garbage, dirt, and grime on the bottom, walls, water, and / or surface of the pool, so that it is sucked into the dust box of the automatic pool cleaning device along with the water flow, filtered through the dust box, trapping the garbage, dirt, and grime in the dust box, and the cleaned water is discharged from the automatic pool cleaning device, thereby achieving the cleaning of the pool.

[0024] When the automatic pool cleaning device 10 performs a cleaning task, it can send garbage / dirt in the water and / or on the water surface into the filtration mechanism of the automatic pool cleaning device, such as a dust box, so as to trap the garbage / dirt in the dust box and discharge the filtered water into the pool.

[0025] Figure 1 The automatic water tank cleaning device 10 shown is merely an example. Those skilled in the art can make changes to it in one or more aspects such as appearance, structure, layout, components, and functions according to actual needs, without departing from the principles of this disclosure.

[0026] When the automatic water tank cleaning device performs cleaning tasks, such as cleaning the water surface, in order to better guide the water flow through the inlet into the dust box, thereby using the water flow to send garbage / dirt into the dust box for cleaning, a corresponding water flow guiding mechanism can be set at the inlet to improve cleaning efficiency.

[0027] As an example, the water flow guiding mechanism may include a rotatable component so that when the rotatable component is driven to rotate by a drive mechanism, it can better guide the water flow into the dust box.

[0028] As an example, the dust box can be a dust box that is detachably installed inside the housing of the automatic pool cleaning device, that is, it can be a detachable dust box.

[0029] According to an embodiment of this disclosure, a water flow guiding mechanism is provided at the water inlet of the dust box of the automatic cleaning device for the water tank. The water flow guiding mechanism includes a rotatable component and a connector. The water flow guiding mechanism is coupled to the dust box through the connector, and the rotatable component is coupled to the connector through a bearing, so that water can be guided into the dust box when the rotatable component is driven to rotate.

[0030] As an example, the aforementioned water inlet may include a water surface inlet for the dust box, such that when the rotatable component of the water flow guiding mechanism rotates, the water flow from the water surface is guided into the water surface inlet of the dust box.

[0031] Figure 2A schematic structure of a dust box for an automatic pool cleaning device according to an embodiment of the present disclosure is shown. Figure 2 As shown, the dustbin 20 includes a water flow guiding mechanism 205. As an example, the water flow guiding mechanism 205 includes a rotating member 210 and a connecting member 220. The rotating member 210 is configured to guide water flow into the dustbin 20 by rotation; the connecting member 220 is configured to couple the water flow guiding mechanism 205 to the dustbin 20, and the rotating member 210 is coupled to the connecting member 220 via at least one bearing.

[0032] As an example, the connector can be coupled to the dust box using a snap-fit ​​method. Figure 2 As shown, for example, the dust box may include a top frame having two opposing sides 230, and the water flow guiding mechanism 205 is engaged with the two sides 230 via the connector 220.

[0033] Figure 3 The structure of the rotating member 210 of the water flow guiding mechanism according to an embodiment of the present disclosure is illustrated schematically. Figure 3 As shown, the rotating member 210 includes a shaft 2105 and at least one blade 2110 arranged along the extension direction of the shaft, the at least one blade 2110 rotating with the rotation of the shaft 2105.

[0034] like Figure 3 As further shown, an opening for water to flow in is provided between the at least one blade 2110 and the shaft 2105.

[0035] like Figure 3 As shown, a plurality of blades 2110 extending axially around the shaft 2105 are arranged around the shaft, and at least one reinforcing rib 2115 is provided between the plurality of blades 2110 and the shaft 2105 to enhance the structural strength of the rotating component.

[0036] Figure 4A The schematic diagram illustrates the specific structure of the rotating member 210 and the connecting member 220 at the connection point. For example... Figure 4A As shown, the shaft of the rotating member 210 has a first end and a second end, and the rotating member 210 is coupled to the corresponding connecting member 220 at the first end and the second end of the shaft, respectively, via bearings. As an example, as described above, the connecting member 220 is snapped onto two opposing sides 230 of the top frame of the dust box.

[0037] Figure 4B It is shown schematically. Figure 4A An enlarged view of the structure within the dashed box. (See image below.) Figure 4BAs shown, one end 2120 of the shaft of the rotating member 210 is coupled to the connecting member 220 through the bearing 240. In other words, a bearing seat for placing the bearing 240 can be provided on the connecting member 220, and one end 2120 of the shaft of the rotating member 210 passes through the bearing, so that the rotating member 210 can rotate relative to the connecting member 220.

[0038] According to an embodiment of this disclosure, at least one seal is provided at the bearing to prevent foreign objects such as sand from entering the position where the rotating part 210 and the connecting part 220 of the water flow guiding mechanism 205 are connected when the automatic cleaning device for the water tank performs cleaning operations. This would cause wear on the shaft end of the rotating part 210 and / or cause the bearing of the rotating part to be jammed by foreign objects, thus affecting the rotation of the rotating part.

[0039] As an example, such as Figure 4B As shown, two seals 260 are provided at the bearing 240, that is, two seals are provided on both sides of the bearing 240 in the axial direction to prevent foreign objects from entering the bearing 240.

[0040] According to embodiments of this disclosure, at least one seal includes a bearing oil seal.

[0041] According to the embodiments included herein, the rotating member 210 may be coupled to the corresponding connecting member 220 at both ends of its shaft via a first bearing and a second bearing, respectively.

[0042] According to at least one embodiment of this disclosure, depending on the installation dimensions and actual requirements, a seal may be provided on at least one side of at least one of the first and second bearings.

[0043] As an example, a first seal can be provided on both sides of the first bearing in the axial direction to prevent foreign objects from entering the first bearing; and / or a second seal can be provided on both sides of the second bearing in the axial direction to prevent foreign objects from entering the second bearing.

[0044] According to at least one embodiment of this disclosure, the rotating component includes at least one of the following: a dial or a paddle, which, when driven to rotate by a drive motor, can guide water flow into the dust box, thereby sending garbage / dirt into the dust box for cleaning.

[0045] According to the above embodiments of this disclosure, a water flow guiding mechanism is provided on the dust box of the automatic pool cleaning device. The water flow guiding mechanism includes a rotating component and a connecting component. The water flow guiding mechanism is coupled to the dust box through the connecting component, and the rotating component is coupled to the connecting component through a bearing. This allows water to be guided into the dust box when the rotating component is driven to rotate. In addition, at least one seal is provided at the bearing to prevent foreign objects such as sand from entering the position where the rotating component and the connecting component of the water flow guiding mechanism are connected during the cleaning operation of the automatic pool cleaning device. This would prevent wear on the shaft end of the rotating component and / or the bearing of the rotating component from being jammed by foreign objects, thus affecting the rotation of the rotating component. This improves the operational reliability of the automatic pool cleaning device and extends the maintenance cycle.

[0046] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "setting," "connection," "linking," "fixing," and "coupling," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communicative connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.
