[0019] Furthermore, terms such as "first," "second," and "third," which relate to sequence, are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. 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.

[0020] 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.

[0021] 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, and a cleaning mechanism 130 (e.g., a roller brush), among other structures / components. As an example, control circuits such as a control unit and an inertial measurement unit (IMU) may be installed within 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 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 travel mechanism, without limitation. As an example, the automatic pool cleaning device 10 may also include a spray mechanism, such that when the automatic pool cleaning device 10 travels along the pool wall, it can utilize a spray nozzle (e.g., from its nozzle direction relative to the top of the body of the automatic pool cleaning device 10)... Figure 1 The pressure generated by the water jet from the nozzle 140 (shown) keeps the water adhering to the pool wall, maintaining stability during movement.

[0022] It should be noted that, as an example, in Figure 1Only one spray nozzle 140 is shown in the figure. However, the automatic pool cleaning device may include multiple spray nozzles, such as two spray nozzles symmetrically arranged on the top of the housing of the automatic pool cleaning device; and / or spray nozzles symmetrically arranged on the front and / or rear sides of the housing of the automatic pool cleaning device, so that it can move by the thrust generated by the water flow sprayed from the spray nozzles whose spray direction is opposite to the direction of travel.

[0023] 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.

[0024] As an example, a filtration mechanism (e.g., a filter basket) and a spray mechanism can be installed inside the housing of an automatic water tank cleaning device. The spray mechanism may include a pump motor and an impeller. The pump motor is configured to drive the impeller to rotate in order to generate a suction force, so that water in the water tank is drawn into the filtration mechanism through the inlet, and the water filtered by the filter basket is discharged into the water tank through the spray nozzle, thereby cleaning the water tank.

[0025] After the automatic pool cleaning device cleans the pool (such as a swimming pool), debris such as hair and leaves in the water may become entangled on the impeller of the spray mechanism. The cleaned dirt may also adhere to the impeller blades of the spray mechanism. In addition, the grates at the spray nozzles also need to be cleaned regularly in order to clean and maintain the automatic pool cleaning device, keep it in good working condition, and extend its service life.

[0026] Therefore, this disclosure proposes a design for the spray nozzle of an automatic water tank cleaning device to be detachable. When it is necessary to clean and maintain the spray mechanism, the spray nozzle cover can be removed to facilitate cleaning and maintenance operations.

[0027] Figure 2 The diagram schematically illustrates the structure of a portion of the housing of an automatic pool cleaning device according to an embodiment of the present disclosure, wherein a portion of the top cover of the housing and components disposed within the housing that are unrelated to the principles of the present disclosure have been removed.

[0028] like Figure 2 As shown, an automatic water tank cleaning device according to an embodiment of the present disclosure includes a housing 110, a water spray nozzle 140 disposed on the housing, and a removable water spray nozzle cover 150.

[0029] Figure 3A The schematic diagram illustrates a partial structure of an automatic pool cleaning device according to an embodiment of the present disclosure, wherein the removable spray nozzle cover 150 is separated from the spray nozzle 140 provided on the housing 110 of the automatic pool cleaning device.

[0030] As an example, such as Figure 3A As shown, a first joint 210 is provided on the spray nozzle cover 150, and a second joint 220 is provided on the housing 110 of the automatic water tank cleaning device. The first joint 210 can engage with the second joint 220.

[0031] As an example, such as Figure 3A As shown, the spray nozzle cover 150 includes an outer edge 240. (As indicated...) Figure 2 As shown, after the first engagement portion 210 engages with the second engagement portion 220, at least a portion of the outer edge 240 is exposed. It can be understood that the first engagement portion 210 may be part of the outer edge 240, with a portion of the first engagement portion 210 exposed after engagement with the second engagement portion 220.

[0032] According to embodiments of this disclosure, the first engagement portion may include a snap fastener, and the second engagement portion may include a slot.

[0033] As an example, when the nozzle cap is fitted onto the nozzle 140, at least a portion of the outer edge of the nozzle cap is exposed by the slot serving as the second joint, where a portion of the first joint 210 is exposed; alternatively, a notch or groove can be formed on the housing corresponding to the outer edge so that when the nozzle cap 150 is fitted onto the nozzle 140, at least a portion of the outer edge of the nozzle cap 150 is exposed. For example, by... Figure 3A The notch or groove 250 shown exposes at least a portion of the outer edge.

[0034] Therefore, when the exposed part is subjected to external force, such as by prying the part with a tool such as a screwdriver or a coin, the first or second joint can deform, causing the first joint to separate from the second joint, thereby facilitating the removal of the nozzle cover from the nozzle.

[0035] As an example, the position of the exposed portion of the outer edge may correspond to the position where the first joint and the second joint engage; as another example, the position of the exposed portion of the outer edge may also differ from the position where the first joint and the second joint engage.

[0036] Figure 3BThe illustration schematically shows the spray nozzle cover 150 engaging with the second engaging portion 220 provided on the housing 110 of the automatic water tank cleaning device via the first engaging portion 210, so that the spray nozzle cover covers the spray nozzle. As an example, the first engaging portion 210 provided on the spray nozzle cover 150 is a snap-fit, and the second engaging portion 220 provided on the housing 110 is a slot. The engagement of the snap-fit ​​and the slot connects the spray nozzle cover 150 to the housing 110, thus covering the spray nozzle.

[0037] Figures 4A-4C The schematic illustration shows the specific structure of the removable nozzle cover and the corresponding nozzle according to an embodiment of the present disclosure.

[0038] like Figure 4A As shown, as an example, a plurality of grid pieces 260 are provided on the inner side of the sidewall of the detachable nozzle cover 150, and a first joint portion 210 is provided on the outer side of the sidewall of the nozzle cover 150.

[0039] like Figure 4A As further illustrated, as an example, a first connector 270 may be provided on the outer side of the sidewall of the detachable nozzle cover 150. The detachable nozzle cover 150 is connected to the housing of the automatic water tank cleaning device through the first connector 270 and the first joint 210 and covers the nozzle provided on the housing.

[0040] According to embodiments of this disclosure, the number of the first connector and the first engagement portion provided on the detachable nozzle cover can be different. For example, such as Figure 4A The number of first connectors 270 shown can be two, while the number of first joints 210 can be one. This creates a foolproof structure to prevent incorrect installation when attaching the removable nozzle cover to the nozzle of the automatic pool cleaning device.

[0041] As an example, such as Figure 4A As shown, the first connector 270 includes a plug-in connector that is connected to the housing via a plug-in method; correspondingly, as Figure 4B As shown, the housing of the automatic water tank cleaning device is provided with a socket 280 that matches the connector.

[0042] As described above, a notch 250 can be formed at a point on the housing corresponding to the outer edge so that at least a portion of the outer edge of the nozzle cover is exposed when the nozzle cover is fitted over the nozzle. Alternatively, at least a portion of the first joint 210 on the outer edge of the nozzle cover can be exposed by a slot serving as the second joint 220. According to an embodiment of the present disclosure, when the nozzle cover is fitted over the nozzle, at least a portion of the exposed outer edge and the connector are located on opposite sides facing the housing, such that when an external force is applied to the exposed portion, the nozzle cover can be pried open relatively easily by using the connector as a fulcrum.

[0043] Figure 4B It is further shown that a second coupling portion 220 in the form of a slot is provided on the housing of the automatic pool cleaning device so as to engage with, for example, Figure 4A The detachable nozzle cover shown is fitted with a first joint 210 in the form of a snap fastener.

[0044] According to embodiments of this disclosure, the second joint and the insertion hole are provided at positions on opposite sides of the housing of the automatic water cleaning device, thereby ensuring stress balance when the removable nozzle cover is installed on the nozzle. For example, as Figure 4C As shown, a second joint 220 and a socket 280 are provided on opposite sides of the housing 110 of the automatic water tank cleaning device (e.g., the front and rear sides of the housing 110).

[0045] According to embodiments of this disclosure, such as Figure 4B As shown, the housing of the automatic water tank cleaning device has a connection port 180 extending toward the inside of the housing at the spray nozzle 140, and a socket 280 and a second connecting part 220 (e.g., a slot) are provided on the side wall of the connection port 180.

[0046] As an example, such as Figure 4B As shown, a stepped surface 190 is provided on the upper edge of the side wall of the connection port 180. When the removable nozzle cover 150 is placed on the nozzle 140, as... Figure 4A At least a portion 290 of the inner wall of the outer edge of the detachable nozzle cover 150 shown is in contact with the stepped surface 190.

[0047] According to an embodiment of the present disclosure, at least a portion of the outer edge of the detachable nozzle cover is exposed, such that when subjected to external force, the first joint of the nozzle cover or the second joint provided on the housing of the automatic water tank cleaning device can deform, causing the first joint to separate from the second joint, thereby allowing the nozzle cover to be easily disassembled.

[0048] As an example, it can be found in the corresponding...Figure 3B The location of the second connecting portion 220 (e.g., a slot) shown can be achieved by using a simple tool, such as a readily available coin, to pry open the exposed outer edge of the nozzle cover. This causes deformation of the first connecting portion 210 (e.g., a snap-fit) on the nozzle cover or the second connecting portion 220 (e.g., the housing corresponding to the slot) on the housing of the automatic pool cleaning device. This separates the first and second connecting portions, facilitating easy removal of the nozzle cover. This method avoids the inconvenience of fixing the nozzle cover to the housing with screws.

[0049] According to embodiments of this disclosure, the spray nozzle cover can be easily installed and removed for cleaning the spray nozzle. For example, when installing the spray nozzle cover, simply align the first joint and the first connector of the spray nozzle cover with the second joint and the insertion hole provided on the housing, respectively, then fasten it onto the spray nozzle and press the spray nozzle cover to connect the spray nozzle cover to the housing, thereby covering the spray nozzle. When it is necessary to clean the spray nozzle and / or the spray nozzle cover, the exposed outer edge of the spray nozzle cover can be pried to deform the first joint on the spray nozzle cover or the second joint on the housing of the automatic water tank cleaning device, causing the first joint and the second joint to separate, thereby removing the spray nozzle cover, reducing cleaning and maintenance time and improving cleaning efficiency.

[0050] 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.

[0051] 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.
