[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.

[0024] like Figure 1 As shown, the automatic water tank cleaning device 10 may include structures / components such as a housing 110, a traveling mechanism 120, and a cleaning mechanism 130. 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 also be provided, and a filtration mechanism, such as a filter basket, may be installed to filter and purify the water entering the filter basket through the inlet, removing impurities, and then discharging the cleaned water through the outlet of the automatic water tank cleaning device.

[0025] 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.

[0028] According to embodiments of this disclosure, in addition to a filtration mechanism (e.g., a filter basket) and a water spraying mechanism, a flow guide may also be provided inside the housing of the automatic water tank cleaning device. As an example, the water spraying mechanism includes a pump motor and an impeller. The pump motor is configured to drive the impeller to rotate, thereby generating a suction force that draws water from the tank into the filtration mechanism through an inlet. The water filtered by the filtration mechanism is then guided by the flow guide and flows through, for example... Figure 1 The water jet 140 shown discharges into the pool.

[0029] According to embodiments of this disclosure, the flow guide may include a flow guide body and a flow guide accessory. As an example, the flow guide accessory is detachably connected to the flow guide body, while the flow guide body is fixedly connected to the housing of the automatic water tank cleaning device.

[0030] According to at least one embodiment of this disclosure, the automatic pool cleaning device may include an openable top cover, and a flow guide accessory may be installed or / removed when the top cover is open.

[0031] According to at least one embodiment of this disclosure, the top cover and the flow guide accessory are integrally formed.

[0032] Figure 2 This is an exploded view schematically showing the automatic pool cleaning device 10 with the housing top cover and the flow guide accessory removed, where the mounting positions of the top cover 210 and the flow guide accessory 220 on the housing of the automatic pool cleaning device 10 are shown by arrows.

[0033] As an example, Figure 2Further shown is a portion 230 of the flow guide body installed inside the housing of the automatic pool cleaning device 10 and a filter mechanism 250 disposed inside the housing of the automatic pool cleaning device 10.

[0034] As an example, Figure 2 It is also shown that, with the housing top cover 210 and the flow guide accessory 220 removed, at least one impeller 240 disposed inside the housing of the automatic pool cleaning device is displayed. The impeller 240 can be rotated by a pump motor to guide water flow through the flow guide and then discharge it into the pool via, for example, a spray nozzle 140.

[0035] According to embodiments of this disclosure, the guide member for an automatic water tank cleaning device may have an inlet end and an outlet end, with an impeller (e.g., an impeller) provided on the inlet end side. Figure 2 The impeller 240 shown is connected to the outlet of the automatic cleaning device for the water tank (e.g., the outlet end of which is connected to the outlet of the automatic cleaning device for the water tank). Figure 1 and / or Figure 2 The spray nozzle 140 shown is wherein the impeller can be driven to guide water flow from the inlet end of the guide member to the outlet end.

[0036] As an example, the flow guide may include a flow guide body and a flow guide accessory, the flow guide accessory being mounted on the flow guide body. The flow guide body has an opening, which is closed when the flow guide accessory is mounted on the flow guide body. When the flow guide accessory is removed from the flow guide body, the impeller can be cleaned through the opening.

[0037] Figure 3 The diagram schematically illustrates the three-dimensional structure of the guide body of the automatic water tank cleaning device according to an embodiment of the present disclosure.

[0038] As an example, such as Figure 3 As shown, the guide body 30 can be provided with an inlet end 310 and an outlet end 320, and an impeller (e.g., ...) is provided on one side of the inlet end 310. Figure 2 The impeller 240 shown is connected to the outlet of the automatic water cleaning device (e.g., the outlet end 320). Figure 1 and / or Figure 2 As shown in the spray nozzle 140), the impeller can be driven to guide water flow from the inlet end of the guide member to the outlet end.

[0039] like Figure 3 As further shown, the guide body 30 may be provided with an opening 330. When the guide accessory is installed on the guide body 30, the opening 330 can be closed by the guide accessory. When the guide accessory is removed from the guide body, the impeller can be cleaned through the opening 330.

[0040] As an example, such as Figure 3 As shown, the opening 330 can be positioned above the guide body 30.

[0041] As an example, such as Figure 3 As shown, the flow guide body 30 may include two symmetrically arranged flow guide pipes 350, and the opening 330 includes a first opening and a second opening, wherein the first opening and the second opening are respectively provided on the two flow guide pipes 350. However, depending on the size and function of the automatic pool cleaning device, the number and relative positional relationship of the flow guide pipes and / or openings are not limited thereto. For example, if the size of the automatic pool cleaning device only allows for one impeller, the flow guide body may accordingly include only one flow guide pipe. Alternatively, if the automatic pool cleaning device has multiple spray nozzles, the number and / or position of the flow guide pipes and openings may be arranged accordingly based on the number and / or position of the spray nozzles.

[0042] As an example, such as Figure 3 As shown, a connecting structure 3500 can be provided between the two guide tubes 350; as an example, the connecting structure 3500 can take the form of a reinforcing rib, and its specific shape, quantity and / or relative positional relationship are not limited here.

[0043] As an example, such as Figure 3 As shown, the guide pipe 350 can be L-shaped, that is, the inlet and outlet of the guide pipe 350 are basically perpendicular.

[0044] As an example, such as Figure 3 As shown, the opening 330 can be set at the bend of the guide pipe 350.

[0045] As an example, such as Figure 3 As shown, the opening 330 can be curved. However, depending on the location and space on the guide body for mounting the guide accessory, the shape of the opening can also be planar, as long as it allows for easy cleaning of the impeller after the guide accessory is removed. There are no restrictions on this.

[0046] As an example, such as Figure 3 As shown, the lower part of the guide body 30 also includes a frame structure 340, which has a hollow cavity for accommodating the impeller.

[0047] According to embodiments of this disclosure, the frame structure of the guide body can be fixedly connected to the housing of the automatic water tank cleaning device, and the guide accessory is detachably connected to the guide body. When the impeller needs to be cleaned, the guide accessory can be removed from the guide body.

[0048] Figure 4The diagram schematically illustrates the three-dimensional structure of a flow guide accessory of an automatic water tank cleaning device according to an embodiment of the present disclosure. For example... Figure 4 As shown, the flow guide accessory 40 includes a first flow guide accessory 410 and a second flow guide accessory 420 that are respectively matched with the shapes of the first opening and the second opening.

[0049] According to at least one embodiment of the present disclosure, snap-fit ​​members are respectively provided on the two sides of the first flow guide accessory and the second flow guide accessory that are far apart from each other; the flow guide tube is provided with a mating member on the side wall near the first opening and the second opening; the flow guide accessory is connected to the flow guide body by snapping the snap-fit ​​member into the mating member.

[0050] For example, such as Figure 4 As shown, first snap-fit ​​members 4110 and 4210 are respectively provided on the opposite sides of the first guide member accessory 410 and the second guide member accessory 420; correspondingly, mating members are provided on the sidewalls of the two guide tubes near the first and second openings. As an example, such as... Figure 3 As shown, the mating parts 3310 and 3320 can be in the form of slots. Thus, the guide accessory 40 can be connected to the guide body 30 by being snapped into the mating parts 3310 and 3320 provided on the side wall of the guide tube 350 through the first snap-fit ​​parts 4110 and 4210 respectively.

[0051] As an example, such as Figure 4 As further shown, second snap-fit ​​members 4120 and 4220 may also be provided on opposite sides of the first guide member attachment 410 and the second guide member attachment 420 (e.g., on the upper parts of the first guide member attachment 410 and the second guide member attachment 420); correspondingly, mating members may be provided on the sidewalls of the two guide tubes near the first opening and the second opening. As an example, such as Figure 3 As shown, the mating parts 3510 and 3520 can be in the form of snap-fit ​​posts. The guide accessory 40 can be connected to the guide body 30 by snapping into the mating parts 3510 and 3520 provided on the side wall of the guide tube 350 through the second snap-fit ​​parts 4120 and 4220 respectively.

[0052] According to embodiments of this disclosure, the first flow guide accessory and the second flow guide accessory may be integrally formed or may be separately configured, and no limitation is made herein.

[0053] For example, such as Figure 4As shown, when the first guide accessory 410 and the second guide accessory 420 are integrally formed, a first connecting structure 4310 and a second connecting structure 4320 can be provided between the first guide accessory 410 and the second guide accessory 420; as an example, the first connecting structure 4310 and the second connecting structure 4320 can be in the form of reinforcing ribs, and their specific shape, quantity and / or relative positional relationship are not limited here.

[0054] As an example, such as Figure 4 As shown, a protrusion can be provided at the bottom of the first connecting structure 4310, while in... Figure 3 The connection structure 3500 between the two guide tubes 350 shown is provided with a locking hole, so that when the guide accessory 40 is installed on the guide body 30, the protrusion can be inserted into the locking hole, thereby making the connection between the guide accessory and the guide body more secure.

[0055] According to the above embodiments of this disclosure, by designing the flow guide of the automatic water tank cleaning device to include a flow guide body and a detachable flow guide accessory, and providing an opening on the flow guide body, the opening is closed by the flow guide accessory when the flow guide accessory is installed on the flow guide body. When the flow guide accessory is removed from the flow guide body, the impeller can be cleaned through the opening. Not only can the impeller be cleaned simply by removing the flow guide accessory when cleaning is needed, but after cleaning, the flow guide accessory can be installed on the flow guide body to form a channel for flow guidance. This improves the stability of the flow guide in guiding water flow, thereby better controlling the position of the automatic water tank cleaning device and reducing the power consumption of the spray mechanism.

[0056] 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.

[0057] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
