Thus, features defined with terms related to order such as "first", "second", "third", etc. may explicitly or implicitly include at least one such feature. In the description of the present disclosure, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0024] In addition, in the drawings, for the sake of clarity of illustration, the dimensions may be exaggerated and are not drawn to actual scale. Throughout the drawings, the same reference numerals generally refer to the same elements.

[0025] Figure 1A Schematically shows the external shape of a pool automatic cleaning device 100 according to an embodiment of the present disclosure. It can perform cleaning operations on the bottom, pool wall, in the water, and on the water surface of a pool (such as a swimming pool) as needed. For example, it is used to clean the garbage in the water, at the bottom, and on the water surface, and clean the dirt on the pool bottom and pool wall. As Figure 1A shown, the pool automatic cleaning device 100 may include structures / components such as a housing 110, a traveling device 120, a cleaning device 130, etc. As an example, the pool automatic cleaning device 100 may further include a buoyancy adjustment device (not shown), so that the pool automatic cleaning device can adjust its depth in the water as needed. For example, it can float on the water surface, dive into the water, or sink to the bottom to perform cleaning operations on the water surface, in the water, or at the bottom. As an example, a control compartment, a power compartment, and a filtration compartment (not shown) may be provided in the housing 100. Among them, control circuits such as a microprocessor, a digital signal processor (DSP), and a microcontroller may be installed in the control compartment, drive devices such as a water pump and a drive motor may be provided in the power compartment, and a filtration device may be provided in the filtration compartment to filter and purify the water entering the interior of the filtration compartment through the water inlet, filter out the debris therein, and discharge the cleaned water out of the pool automatic cleaning device through the water outlet. As an example, Figure 1A shows that the traveling device 120 may include a crawler-type traveling device on both sides of the lower part of the pool automatic cleaning device 100, so that the pool automatic cleaning device can travel in the water, on the pool bottom, or on the pool wall, thereby performing corresponding cleaning operations. However, the traveling device is not limited to Figure 1A the type shown, but may include, for example, a wheel-type traveling device, which is not limited herein. As an example, the cleaning device 130 may include components such as a rotary brush provided on the front side and / or the rear side of the pool automatic cleaning device.

[0026] As an example, Figure 1AAlso shown are a drain opening 140 symmetrically arranged about the longitudinal axis of the body of the automatic pool cleaning device 100 at the rear side of the housing 110 of the automatic pool cleaning device 100, and a drain opening 150 symmetrically arranged about the longitudinal axis of the body of the automatic pool cleaning device at the top of the housing 110; and Figure 1B One of the drain openings 160 symmetrically arranged at the front side of the housing 110 of the automatic pool cleaning device 100 is further shown.

[0027] In addition, the automatic pool cleaning device 100 can adopt a water spraying device as an auxiliary traveling device so that the reaction force generated by the water flow sprayed by the water spraying device can be used to push the automatic pool cleaning device to travel on the water surface, in the water, at the bottom of the pool and / or on the pool wall. In this case, the water flow sprayed by the water spraying device can be guided to one of the drain openings 140-160 provided on the housing 110 of the automatic pool cleaning device 100, thereby generating thrusts in different directions.

[0028] For example, as Figure 1A-1B shown, when the water flow sprayed by the water spraying device is guided to the drain opening 140 provided at the rear side of the housing 110 and discharged, the automatic pool cleaning device 100 can generate a forward thrust parallel to the longitudinal axis of the body of the automatic pool cleaning device, pushing the automatic pool cleaning device 100 forward; when the water flow sprayed by the water spraying device is guided to the drain opening 160 provided at the front side of the housing 110 and discharged, the automatic pool cleaning device 100 can generate a backward thrust parallel to the longitudinal axis of the body of the automatic pool cleaning device, pushing the automatic pool cleaning device 100 backward; when the water flow sprayed by the water spraying device is guided to the drain opening 150 provided at the top of the housing 110 and discharged, the automatic pool cleaning device 100 can generate a pressure towards the bottom of the automatic pool cleaning device 100; this pressure can be both the power for the automatic pool cleaning device 100 to dive in the water and the pressure applied towards the bottom when the automatic pool cleaning device 100 travels on the pool wall of the pool, so as to improve the adhesion between the automatic pool cleaning device 100 and the pool wall and maintain the stability of its body in a vertical state.

[0029] Although Figure 1A-1B the overall appearance of the automatic pool cleaning device of the embodiment of the present disclosure is illustrated, it should be understood that Figure 1A-1B the shown automatic pool cleaning device 100 is only an example, and those skilled in the art can make changes to it in one or more aspects such as appearance, structure, layout, components, functions, etc. according to actual needs without departing from the principle of the present disclosure. For example, the positions, shapes and / or quantities of the above-mentioned drain openings 140-160 provided on the housing 110 of the automatic pool cleaning device 100 can be adjusted accordingly according to the actual design requirements of the automatic pool cleaning device, which are not limited herein.

[0030] According to an embodiment of the present disclosure, a water spraying device for a pool automatic cleaning device is provided, which can change the direction of the sprayed water flow based on the operation requirements of the pool automatic cleaning device, and discharge the water flow through a corresponding drain outlet on the housing of the pool automatic cleaning device, so as to control the traveling state of the pool automatic cleaning device.

[0031] As shown in Figure 2 FIG. 6, the water spraying device 20 for a pool automatic cleaning device according to an embodiment of the present disclosure may include: a water pump 210; a housing 220, wherein the housing 220 may include a water inlet 2210 and a plurality of water outlets 2220, 2230 and 2240; the water pump is used to drive the water flow to flow into the housing from the water inlet and discharge from a target water outlet selected from the plurality of water outlets; a water flow guiding mechanism 230, at least partially installed in the housing 220, for communicating the target water outlet with the water inlet and closing other water outlets.

[0032] As an example, as shown in Figure 2 FIG. 6, in the above water spraying device, the plurality of water outlets include a first water outlet 2220, a second water outlet 2230 and a third water outlet 2240, the water outlet direction of the first water outlet 2220 is towards the top direction of the pool automatic cleaning device; the water outlet direction of the second water outlet 2230 is towards the forward direction of the pool automatic cleaning device; the water outlet direction of the third water outlet 2240 is towards the backward direction of the pool automatic cleaning device.

[0033] As an example, the above water spraying device 20 may further include Figure 2 a control module not shown in FIG. 6, for selecting a target water outlet from the plurality of water outlets, and its installation position is not limited, and it may be independent of the water spraying device 20, for example, installed outside the water spraying device. In addition, a separate control module may not be provided for the water spraying device, but the water spraying device and other devices of the pool automatic cleaning device, such as a cleaning mechanism, a traveling mechanism, a driving mechanism, etc., may share one or more control modules or control devices; or the control module function of the water spraying device may be integrated into the control device or control module of the pool automatic cleaning device.

[0034] As an example, the control device or control module of the pool automatic cleaning device may include, but is not limited to, for example, a control unit such as a central processing unit (CPU), a microprocessor (MPU), a digital signal processor (DSP), etc. equipped in the pool automatic cleaning device.

[0035] According to an embodiment of the present disclosure, based on the operation requirements and / or instructions of the pool automatic cleaning device, a target water outlet can be selected from the plurality of water outlets through the control device or control module of the pool automatic cleaning device.

[0036] For example, when the automatic pool cleaning device needs to clean the pool wall and / or needs to travel on the pool wall, the control device or control module of the automatic pool cleaning device can select the first water outlet 2220 from the multiple water outlets 2220, 2230, and 2240 as the target water outlet. Thus, the water flow is driven by the water pump 210 to flow into the housing 220 of the water spraying device from the water inlet 2210 and discharged from the first water outlet 2220. As an example, the first water outlet 2220 can be aligned with Figure 1A the drain outlet 150 shown, so that the water flow driven by the water pump can be discharged into the pool through the drain outlet 150 at the top of the housing of the automatic pool cleaning device. By discharging the water flow through the drain outlet 150 provided at the top of the housing of the automatic pool cleaning device, a force can be generated to be applied to the bottom of the automatic pool cleaning device, thereby increasing the adhesion of the traveling mechanism of the automatic pool cleaning device to the pool wall and improving its traveling stability on the pool wall.

[0037] As another example, when the automatic pool cleaning device travels on the water surface, the control device or control module of the automatic pool cleaning device can select the third water outlet 2240 from the multiple water outlets 2220, 2230, and 2240 as the target water outlet. Thus, the water flow is driven by the water pump 210 to flow into the housing of the water spraying device from the water inlet 2210 and discharged from the third water outlet 2240. As an example, the third water outlet 2240 can be aligned with Figure 1A the drain outlet 140 shown, so that the water flow driven by the water pump can be discharged into the pool through the drain outlet 140 provided at the rear of the housing of the automatic pool cleaning device. By discharging the water flow through the drain outlet 140 provided at the rear of the housing of the automatic pool cleaning device, a thrust can be generated to push the automatic pool cleaning device forward, enabling the automatic pool cleaning device to travel forward on the water surface.

[0038] As yet another example, when the automatic pool cleaning device travels on the water surface, the control device or control module of the automatic pool cleaning device can select the second water outlet 2230 from the multiple water outlets 2220, 2230, and 2240 as the target water outlet. Thus, the water flow is driven by the water pump 210 to flow into the housing of the water spraying device from the water inlet 2210 and discharged from the second water outlet 2230. As an example, the second water outlet 2230 can be aligned with Figure 1B the drain outlet 160 shown, so that the water flow driven by the water pump can be discharged into the pool through the drain outlet 160 provided at the front of the housing of the automatic pool cleaning device. By discharging the water flow through the drain outlet 160 provided at the front of the housing of the automatic pool cleaning device, a thrust can be generated to push the automatic pool cleaning device backward, enabling the automatic pool cleaning device to retreat on the water surface.

[0039] As Figure 1A-1BAs shown, two drain outlets 160 can be symmetrically arranged at the front of the housing along the longitudinal axis of the body of the automatic pool cleaning device, two drain outlets 140 can be symmetrically arranged at the rear of the housing, and / or two drain outlets 150 can be symmetrically arranged at the top of the housing. And by controlling the water pump 210, different controls can be achieved for the flow rate and / or velocity of the water sprayed from the two drain outlets arranged on both sides. For example, the flow rate and / or velocity of draining water from the two drain outlets 140 can be controlled separately to be different from each other, and even one of the drain outlets can be closed, so that the automatic pool cleaning device can be steered.

[0040] According to an embodiment of the present disclosure, in the above-mentioned water spraying device, the water outlet directions of the plurality of water outlets are different from each other, and at least one of them can be selected as the target water outlet. For example, in the above-mentioned water spraying device 20, the water outlet directions of the plurality of water outlets 2220, 2230 and 2240 are different from each other, and the control device or control module of the automatic pool cleaning device can select 2220, 2230 or 2240 as the target water outlet based on specific operation requirements and / or traveling states.

[0041] As an example, as Figure 2 shown, the water pump 210 can include a pump motor 2110 and an impeller 2120. Among them, the pump motor 2110 can drive the impeller 2120 to rotate under the control of the control device or control module of the automatic pool cleaning device, so as to drive the water flow to enter the housing of the water spraying device through the water inlet 2210. As an example, at least a part of the water pump 210 can be located inside the housing of the water spraying device. For example, the impeller 2120 of the water pump 210 can be located inside the housing of the water spraying device.

[0042] Figure 3 Schematically shows the external shape of the water spraying device according to an embodiment of the present disclosure. As Figure 3 shown, the water spraying device 30 can further include a driving mechanism (such as a driving motor) 310. The water flow guiding mechanism 230 can include a plurality of baffles; among them, the driving mechanism 310 can be arranged outside the housing of the water spraying device and drive the water flow guiding mechanism 230 to rotate through the driving shaft 3110. As an example, the water flow guiding mechanism 230 can include a plurality of baffles. By controlling the water flow guiding mechanism 230 to rotate to a corresponding position through the driving mechanism 310, at least one of the plurality of baffles can be rotated to a position where the target water outlet is communicated with the water inlet, and at least another one of the plurality of baffles can be rotated to a position where the water flow channel between other water outlets and the water inlet is blocked, thereby connecting the target water outlet with the water inlet and closing the other water outlets of the housing, so that the water flow driven by the water pump 210 enters the housing of the water spraying device through the water inlet 2210 of the housing and is discharged through the target water outlet (which can be the first water outlet 2220, the second water outlet 2230 or the third water outlet 2240).

[0043] As an example, such as Figure 2 and Figure 3 schematically shown, the water spraying devices 20, 30 can be individually equipped with a water pump 210 and / or a driving mechanism 310. Thus, as Figure 1A-1B shown, when the water spraying devices are symmetrically arranged on both sides along the longitudinal axis of the body of the automatic pool cleaning device, for example, when the water spraying devices are respectively arranged under the housing of the automatic pool cleaning device at the corresponding positions of the drainage outlets 140 - 160 on both sides as Figure 1A-1B shown, the water spraying flow rate / velocity of the drainage outlets on both sides of the automatic pool cleaning device can be independently controlled, and / or the drainage directions of the drainage outlets on both sides can be independently controlled, so as to more flexibly and precisely control the traveling attitude of the automatic pool cleaning device.

[0044] As another example, when the water spraying devices are symmetrically arranged on both sides along the longitudinal axis of the body of the automatic pool cleaning device, for example, when the water spraying devices are respectively arranged under the housing of the automatic pool cleaning device at the corresponding positions of the drainage outlets 140 - 160 on both sides as Figure 1A-1B shown, the water spraying devices on both sides can also share a water pump to synchronously control the water spraying flow rate / velocity of the drainage outlets on both sides. Similarly, the water spraying devices on both sides can also share a driving mechanism. For example, through a driving motor, the water flow guiding mechanisms of the water spraying devices on both sides are driven to rotate synchronously by a transmission mechanism to synchronously control the water spraying directions of the drainage outlets on both sides. Thereby, the control process can be simplified, the installation space can be reduced, and the cost of the automatic pool cleaning device can be lowered.

[0045] Figure 4 Schematically shows the water flow guiding mechanism and the driving mechanism of the water spraying device according to an embodiment of the present disclosure. As Figure 4 shown, the water flow guiding mechanism 230 includes a plurality of baffles 2310, 2320, and 2330. Among them, the size of the baffle 2310 is larger than the sizes of the baffles 2320 and 2330 on both sides of it. That is to say, the baffle 2310 is a large baffle, and the baffles 2320 and 2330 are small baffles. As an example, the small baffles 2320 and 2330 on both sides can be connected to the large baffle 2310 through the support structures 2410 and 2420. On the other hand, the support structures 2410 and 2420 can also serve as the reinforcing ribs of the water flow guiding mechanism, playing a role in enhancing the structural strength of the water flow guiding mechanism.

[0046] It should be noted that Figure 4 only shows an exemplary mechanism of the water flow guiding mechanism proposed according to the principle of the present disclosure. The shape, position, and number of the support mechanisms therein are not limited herein, as long as it can achieve connecting the small baffle to the large baffle and enabling the large baffle and the small baffle to rotate synchronously with the rotation of the driving shaft.

[0047] Similarly, Figure 4 only the respective baffles included in the water flow guiding mechanism are schematically shown, and the shape, size, number, and position of the baffles are not limited herein, as long as it is possible to connect the target water outlet selected from the multiple water outlets of the housing to the water inlet of the housing under the control of the driving mechanism, while closing the other water outlets.

[0048] As Figure 4 shown, the driving mechanism 310 is coupled to the water flow guiding mechanism 230 through the driving shaft 3110. As an example, a shaft cylinder 2340 is provided at the central position of the baffle 2310 of the water flow guiding mechanism 230, and the shaft cylinder 2340 can be sleeved on the driving shaft 3110, so that the driving mechanism (such as a driving motor) 310 can drive the water flow guiding mechanism 230 to rotate through the driving shaft 3110, thereby driving the large baffle and the small baffle to rotate.

[0049] Figure 5 Schematically shows the outer shape of the housing of the water spraying device according to an embodiment of the present disclosure. As Figure 5 shown, the housing 220 of the water spraying device forms a hollow chamber 2202 and multiple water outlet pipes 2204, 2206, and 2208; wherein, the chamber 2202 can accommodate the water flow guiding mechanism 230 as Figure 4 shown and has a space in which the water flow guiding mechanism 230 can rotate. In addition, each of the water outlet pipes includes a water inlet and a water spraying port, and the water spraying port can be used as the water outlet of the housing of the water spraying device. For example, the water spraying port of the water outlet pipe 2204 can be used as the first water outlet 2220 of the housing of the water spraying device, the water spraying port of the water outlet pipe 2206 can be used as the second water outlet 2230 of the housing of the water spraying device, and the water spraying port of the water outlet pipe 2208 can be used as the third water outlet 2240 of the housing of the water spraying device; wherein, at least one of the multiple water outlet pipes can be communicated with the water inlet via the chamber.

[0050] As an example, as Figure 5 shown, the housing of the water spraying device can also form a water inlet pipe 2212, wherein the water inlet of the water inlet pipe 2212 can be used as the water inlet of the housing of the water spraying device, and as Figure 3 shown, the housing of the water spraying device can be detachably connected to the pump pipe 2112 that houses the impeller of the water pump through the water inlet pipe 2212, so as to facilitate the maintenance of the housing and the cleaning of the impeller.

[0051] As another example, the water inlet pipe of the housing can be shared with the pump pipe that houses the impeller of the water pump, that is, the water inlet pipe of the housing and the pump pipe that houses the impeller of the water pump are no longer separately provided. The specific setting method can be adjusted accordingly according to the structure, size, etc. requirements of the pool automatic cleaning device, and is not limited herein.

[0052] As Figure 5 further shown, a shaft hole is also provided on the housing of the water spraying device so that the drive shaft 3110 of the drive mechanism 310 as shown in Figure 4 can pass through the shaft hole 2216 and the shaft cylinder 2340 of the water flow guiding mechanism 230 is sleeved on the drive shaft 3110. In addition, at the position of the inner wall surface of the housing of the water spraying device facing the shaft hole 2216, a shaft seat 2218 can be correspondingly provided to accommodate and support the end of the drive shaft 3110 passing through the shaft cylinder 2340 of the water flow guiding mechanism 230.

[0053] As an example, the water outlet direction of the first water outlet 2220 is towards the top direction of the automatic pool cleaning device; the water outlet direction of the second water outlet 2230 is towards the forward direction of the automatic pool cleaning device; the water outlet direction of the third water outlet 2240 is towards the backward direction of the automatic pool cleaning device.

[0054] In addition, when the water flow guiding mechanism 230 as shown in Figure 4 rotates in the chamber 2202 of the housing of the water spraying device as shown in Figure 5 when the water flow guiding mechanism rotates to a certain position, the small baffle can open the water inlet of the water outlet pipe communicating with the target water outlet, and the large baffle will close the water inlets of the water outlet pipes communicating with other water outlets. As an example, the size of the small baffle is not less than the inner diameters of the water inlets of the water outlet pipes communicating with the second water outlet and the third water outlet respectively.

[0055] According to an embodiment of the present disclosure, the water flow guiding mechanism can be rotated to at least a first position, a second position and a third position; when the water flow guiding mechanism rotates to the first position, the first water outlet communicates with the water inlet, and the small baffle closes the water inlets of the water outlet pipes communicating with the second water outlet and the third water outlet respectively; when the water flow guiding mechanism rotates to the second position, the second water outlet communicates with the water inlet, and the large baffle closes the water inlets of the water outlet pipes communicating with the first water outlet and the third water outlet respectively; when the water flow guiding mechanism rotates to the third position, the third water outlet communicates with the water inlet, and the large baffle closes the water inlets of the water outlet pipes communicating with the first water outlet and the second water outlet respectively.

[0056] As an example, the water flow guiding mechanism 230 can be rotated to the first position by the drive mechanism 310 as shown in Figure 4 via the drive shaft 3310; for example, as shown in Figure 6AAs shown, when the water flow guiding mechanism 230 rotates to the first position, the first water outlet 2220 communicates with the water inlet 2210 of the housing. The small baffles 2320 and 2330 can close the water inlets of the water outlet pipes 2206 and 2208 that communicate with the second water outlet 2230 and the third water outlet 2240 respectively, so that the water flow driven by the water pump flows along Figure 6A the direction indicated by the arrow, that is, enters the housing through the water inlet 2210 and is discharged through the first water outlet 2220. As an example, in the Figure 6A shown situation, the second water outlet pipe 2206 and the third water outlet pipe 2208 can be symmetrically arranged, and their pipe center lines coincide. The first position can be the position where the water flow guiding mechanism 230 rotates to make the plane where the large baffle 2310 is located present a perpendicular angle with the pipe center lines of the second / third water outlet pipes 2206 and 2208. At this position, the small baffles 2320 and 2330 respectively block the water inlets of the second water outlet pipe 2206 and the third water outlet pipe 2208, so that the water can only flow into the water inlet of the first water outlet pipe 2204 and is discharged through the first water outlet 2220 of the housing.

[0057] As an example, by driving the water flow guiding mechanism 230 via the driving shaft 3310 by the driving mechanism 310 as shown in Figure 4 , the water flow guiding mechanism 230 can be rotated to the second position; for example, as shown in Figure 6B , when the water flow guiding mechanism 230 rotates to the second position, the second water outlet 2230 communicates with the water inlet 2210 of the housing. The large baffle 2310 can close the water inlets of the water outlet pipes 2204 and 2208 that communicate with the first water outlet 2220 and the third water outlet 2240 respectively, so that the water flow driven by the water pump flows along Figure 6B the direction indicated by the arrow, that is, enters the housing through the water inlet 2210 and is discharged through the second water outlet 2230. As an example, in the Figure 6B shown situation, the second position can be the position where the water flow guiding mechanism 230 rotates to make the plane where the large baffle 2310 is located present a 135-degree angle with the pipe center line of the third water outlet pipe 2208. At this position, the large baffle 2310 blocks the water inlets of the first water outlet pipe 2204 and the third water outlet pipe 2208, so that the water can only flow into the water inlet of the second water outlet pipe 2206 and is discharged through the second water outlet 2230 of the housing.

[0058] As an example, by driving the water flow guiding mechanism 230 via the driving shaft 3310 by the driving mechanism 310 as shown in Figure 4 , the water flow guiding mechanism 230 can be rotated to the third position; for example, as shown in Figure 6CAs shown, when the water flow guiding mechanism 230 rotates to the third position, the third water outlet 2240 communicates with the water inlet 2210 of the housing. The large baffle 2310 can close the water inlets of the water outlet pipes 2204 and 2206 that communicate with the first water outlet 2220 and the second water outlet 2230 respectively, so that the water flow driven by the water pump flows along Figure 6C the direction indicated by the arrow, that is, enters the housing through the water inlet 2210 and is discharged through the third water outlet 2240. As an example, in the Figure 6C shown situation, the third position can be the position where the water flow guiding mechanism 230 rotates to make the plane where the large baffle 2310 is located present a 45-degree angle with the pipe center line of the third water outlet pipe 2208. At this position, the large baffle 2310 blocks the water inlets of the first water outlet pipe 2204 and the second water outlet pipe 2206, so that the water can only flow into the water inlet of the third water outlet pipe 2208 and is discharged through the third water outlet 2240 of the housing.

[0059] In addition, although as Figure 1A-1B shown, a grille is used at the drain outlet 140 - 160 provided on the housing of the pool automatic cleaning device as a safety protection to prevent garbage / foreign objects in the pool from entering the drain outlet; however, when using the water flow guiding mechanism 230 as Figure 4 shown, its baffle can also play a safety protection role. Thus, the grille can no longer be provided at the drain outlet 140 - 160, so as to reduce the weight of the pool automatic cleaning device and its manufacturing cost.

[0060] According to another embodiment of the present disclosure, the water flow guiding mechanism may further include a rotatable pipe, and the rotatable pipe can rotate inside the housing of the water spraying device under the drive of a drive mechanism, so as to realize the communication between the target water outlet and the water inlet.

[0061] As an example, Figure 7A schematically shows another structure of the housing of the water spraying device 70 and the water flow guiding mechanism according to an embodiment of the present disclosure. As Figure 7A shown, the housing 710 includes a water inlet 7110 and a plurality of water outlets 7120, 7130, and 7140; among them, the water outlet directions of the plurality of water outlets are different from each other; for example, the water outlet direction of the first water outlet 7120 is towards the top direction of the pool automatic cleaning device; the water outlet direction of the second water outlet 7130 is towards the forward direction of the pool automatic cleaning device, and the water outlet direction of the third water outlet 7140 is towards the backward direction of the pool automatic cleaning device, that is, the second water outlet 7130 and the third water outlet 7140 are symmetrically arranged.

[0062] At least a part of the rotatable pipe 720 can be accommodated in the chamber formed by the housing of the housing 710. As Figure 7AAs shown, the rotatable pipe 720 can be driven to rotate by a driving mechanism (such as a driving motor) 730 via a driving shaft 7310 and a transmission mechanism 7320, so that the water outlet of the rotatable pipe 720 can be aligned with a target water outlet selected from multiple water outlets of the housing 710. For example, it can be aligned with the first water outlet 7120, the second water outlet 7130, or the third water outlet 7140 selected by the control device or control module of the pool automatic cleaning device, realizing the connection between the target water outlet and the water inlet of the housing, so as to spray water towards the top, the forward direction, or the backward direction of the pool automatic cleaning device. Thus, different-direction thrusts can be provided for the pool automatic cleaning device based on the operation requirements and / or instructions of the pool automatic cleaning device, controlling the traveling attitude of the pool automatic cleaning and improving its stability when traveling on the pool wall.

[0063] As an example, as Figure 7A-7B shown, a transmission gear 7210 can be provided on the outer periphery of the water inlet of the rotatable pipe 720 as the transmission mechanism, so that the rotatable pipe 720 can be driven to rotate by the driving motor 730 via the driving shaft 7310.

[0064] It should be noted that although not shown in Figure 7A-7B , a water pump such as Figure 2-3 shown can be used to drive water flow to flow into the housing 710 from the water inlet 7110 and discharge from the target water outlet.

[0065] According to an embodiment of the present disclosure, a pool automatic cleaning device is also proposed, which includes the water spraying device described above in combination with Figure 2-Figure 7B . As an example, water spraying devices can be respectively provided under the housing of the pool automatic cleaning device at positions corresponding to the two-side drain openings 140-160 of the pool automatic cleaning device as shown in Figure 1A-1B , so that different-direction thrusts can be provided for the pool automatic cleaning device by controlling the water spraying devices to spray water towards different drain openings, thereby controlling the traveling and turning of the pool automatic cleaning device.

[0066] Accordingly, several aspects of the present disclosure have been presented above with reference to various apparatuses and methods. These apparatuses and methods are illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints of the overall system. For example, a control device or a control module may include any circuit and / or module having data processing capabilities and / or instruction execution capabilities and suitable for controlling a pool automatic cleaning device, such as a central processing unit (CPU), a microprocessor (MPU), a digital signal processor (DSP), a field programmable gate array (FPGA), etc., and may be configured, for example, to perform data processing and / or control related to the cleaning operation and / or other functions of the pool automatic cleaning device according to program instructions stored in a memory (not shown in the figure) within the pool automatic cleaning device, instructions from a control terminal and / or a control panel (not shown in the figure) of the pool automatic cleaning device, etc.

[0067] Thus, in one or more example embodiments, the described functions can be implemented using hardware, software, or any combination thereof. If implemented in software, these functions can be stored or encoded as one or more instructions or codes on a computer-readable medium. The computer-readable medium includes computer storage media.
