Therefore, a feature defined with terms such as "first," "second," and "third," which relate to sequence, may explicitly or implicitly include at least one of those features. In the description of this disclosure, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0022] 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.

[0023] 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 filter basket, may also be included to filter and purify the water entering the filter basket through the inlet, removing impurities, and discharging the cleaned water from the automatic pool cleaning device through the outlet. As an example, Figure 1The 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.

[0024] 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 filter basket of the automatic pool cleaning device along with the water flow, filtered through the filter basket, trapping the garbage, dirt, and grime in the filter basket, and the cleaned water is discharged from the automatic pool cleaning device, thereby achieving the cleaning of the pool.

[0025] When the automatic pool cleaning device 10 performs a cleaning task on the water surface, it can send garbage / dirt on the water surface into the filter mechanism of the automatic pool cleaning device, such as a dust box, through the water flow through the water surface inlet 140 of the automatic pool cleaning device, thereby trapping the garbage / dirt in the dust box and discharging the filtered water into the pool.

[0026] 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.

[0027] When the automatic cleaning device for the pool is performing cleaning tasks on the water surface, in order to better guide the water flow through the water inlet into the dust box, and thus use the water flow to send the garbage / dirt into the dust box for cleaning, a corresponding water flow guiding mechanism can be set at the water inlet to improve cleaning efficiency.

[0028] According to embodiments of this disclosure, by providing a rotatable component at the water inlet of the removable dust box of the automatic pool cleaning device, the rotatable component is coupled to the removable dust box. This allows the rotatable component to be coupled to a transmission mechanism of the automatic pool cleaning device when the removable dust box is installed in the internal chamber of the device. This enables the transmission mechanism to drive the rotatable component to rotate, guiding water flow into the water inlet of the removable dust box. When the removable dust box is removed from the internal chamber of the automatic pool cleaning device, the rotatable component can be separated from the transmission mechanism along with the dust box, i.e., separated from the body of the automatic pool cleaning device. This facilitates easy cleaning and / or maintenance of the rotatable component, improving the user experience.

[0029] Specifically, according to embodiments of this disclosure, an automatic water tank cleaning device is proposed, comprising: a housing having a hollow chamber with a first opening; and a removable dust box detachably installed in the hollow chamber via the first opening, wherein the removable dust box has a water surface inlet. As an example, the removable dust box further includes a rotatable component disposed at the water surface inlet, the rotatable component being configured to guide water flow through the water surface inlet into the removable dust box during rotation.

[0030] Figure 2 The schematic diagram illustrates the main structure of an automatic pool cleaning device according to an embodiment of the present disclosure after the top cover has been removed. For example... Figure 2 As shown, the automatic water tank cleaning device 20 includes a housing 210, wherein a hollow chamber 220 is provided inside the housing 210. The hollow chamber 220 has an opening, and a removable dust box 230 can be installed inside the hollow chamber 220 through the opening.

[0031] As an example, the hollow chamber 210 described above can be fixed to the housing base of the automatic water tank cleaning device in the form of a middle frame structure.

[0032] Figure 3A This is a schematic diagram illustrating a hollow chamber employing a mid-frame structure 30 according to an embodiment of the present disclosure. (See diagram below.) Figure 3A As shown, the middle frame structure 30 has a first opening 310, through which the detachable dust box can be installed into the interior of the middle frame structure 30, and the middle frame structure 30 can be fixedly installed to the bottom of the housing of the automatic water tank cleaning device.

[0033] Figure 3B This illustrates a scenario where a removable dustbin 40, according to an embodiment of this disclosure, is mounted to the middle frame structure 30. For example... Figure 3BAs shown, the removable dust box 40 has a water surface inlet 410 and also includes a rotatable component 420 disposed at the water surface inlet 410. The rotatable component 420 is configured to guide water flow through the water surface inlet 410 into the removable dust box when rotating, thereby allowing garbage / dirt to be sent into the removable dust box by water flow to clean the pool and / or water body.

[0034] It should be noted that when the aforementioned removable dust box 40 is installed into the hollow cavity (e.g., the middle frame structure 30) of the housing of the automatic water tank cleaning device and the top cover of the housing of the automatic water tank cleaning device is closed, the upper opening 430 of the removable dust box 40 will be closed by the top cover of the housing. When the automatic water tank cleaning device performs water surface cleaning operation, the garbage on the water surface will enter the dust box through the water surface inlet 410 of the removable dust box with the water flow, thereby being intercepted by the removable dust box 40 to filter the water flow, and the filtered water will be discharged into the water tank.

[0035] Figure 4 This illustrates a scenario where the removable dustbin, according to an embodiment of the present disclosure, is partially removed from the mid-frame structure. For example... Figure 4 As shown, for example, the removable dust box 40 can be removed from the mid-frame structure 30 to clean the garbage / dirt collected in the removable dust box, or to maintain, service or replace the filter of the removable dust box 40.

[0036] like Figure 4 As further shown, the rotatable assembly 420 of the removable dust box includes a shaft 440 and at least one blade 450 arranged along the extending direction of the shaft 440, the at least one blade rotating with the shaft. As an example, a drive gear 460 is provided at at least one end of the shaft.

[0037] As an example, such as Figure 4 As shown, the removable dust box 40 has two side frames 470 facing each other, and the two ends of the shaft 440 extend through the two side frames 470 to the outside of the removable dust box. The shaft 440 is rotatable relative to the side frames 470 by the drive gear 460.

[0038] According to an embodiment of this disclosure, a drive motor and a transmission mechanism are also provided inside the housing of the automatic water tank cleaning device. When the removable dust box is installed in the hollow cavity, the transmission mechanism is coupled to the rotatable component of the removable dust box, and the drive motor is configured to drive the rotatable component to rotate via the transmission mechanism. When the removable dust box is removed from the hollow cavity, the transmission mechanism is separated from the rotatable component.

[0039] For clarity, Figure 4The housing of the automatic pool cleaning device is omitted; instead, the relative position of the overall structure of the drive motor and transmission mechanism 50 to the hollow chamber 30 is schematically shown.

[0040] According to an embodiment of this disclosure, the transmission mechanism 50 includes a first transmission gear, which meshes with the drive gear when the detachable dust box is installed in the hollow chamber.

[0041] Combination Figure 3A As shown, the first transmission gear 510 can be disposed on the inner side of the side wall of the hollow chamber 30. For example, when the removable dust box 40 is installed in the hollow chamber 30, the first transmission gear 510 can mesh with the drive gear 460; and when the removable dust box 40 is removed from the hollow chamber 30, the first transmission gear 510 can be separated from the drive gear 460.

[0042] Figure 5 The schematic diagram illustrates the specific structure of the drive motor and transmission mechanism 50. For example... Figure 5 As shown, the transmission mechanism also includes a second transmission gear 520, which is coaxial with the first transmission gear 510 shown in FIG3 and is disposed on the outside of the side wall of the hollow cavity 30.

[0043] According to an embodiment of this disclosure, the transmission mechanism further includes a drive gear set configured to transmit driving force from the drive motor to the second transmission gear; wherein the drive gear set and the drive motor are disposed on the outer side of the sidewall of the hollow cavity.

[0044] As an example, Figure 5 The structure of the drive gear set and drive motor is further illustrated schematically. For example... Figure 5 As shown, the drive gear set may include: a first drive gear 530, which is driven to rotate by the output shaft of the drive motor 610; and a second drive gear 540, which transmits the driving force from the output shaft of the drive motor 610 to the second transmission gear 520.

[0045] As an example, the second drive gear 540 may include a first gear ring and a second gear ring arranged coaxially side by side, wherein the first gear ring meshes with the first drive gear 530 and the second gear ring meshes with the second transmission gear 520.

[0046] According to embodiments of this disclosure, the rotatable component at the water inlet of the detachable dust box may include a dial or a paddle. When driven to rotate by a drive motor, it can guide water flow into the water inlet of the detachable dust box, thereby sending garbage / dirt into the dust box for cleaning.

[0047] According to the above embodiments of this disclosure, by providing a rotatable component at the water inlet of the removable dust box of the automatic water tank cleaning device, when the removable dust box is installed inside the hollow cavity of the automatic water tank cleaning device, the rotatable component is coupled to the transmission mechanism equipped with the automatic water tank cleaning device, thereby enabling the rotatable component to rotate through the transmission mechanism to guide water flow into the water inlet of the removable dust box; and when the removable dust box is removed from the hollow cavity, the rotatable component can be separated from the transmission mechanism together with the removable dust box, that is, separated from the body of the automatic water tank cleaning device, which facilitates cleaning and / or maintenance of the rotatable component and improves the user experience.
