[0033] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0034] Please refer to Figures 1 to 4 A swimming pool cleaning robot comprises a main body 1 and a floating posture adjustment module, wherein the main body 1 can float on the surface of the swimming pool or sink to the bottom of the swimming pool, the main body 1 is provided with a water inlet 11 for absorbing water into the main body, the floating posture adjustment module is arranged in the main body 1, and the floating posture adjustment module is used to adjust the floating posture of the swimming pool cleaning robot in the water; wherein, when the swimming pool cleaning robot floats on the surface of the swimming pool, the water inlet 11 is close to or facing the surface of the swimming pool; when the swimming pool cleaning robot sinks to the bottom of the swimming pool, the water inlet 11 is close to or facing the bottom of the swimming pool.

[0035] The core invention point of the present invention is that the swimming pool cleaning robot provided by the present invention only needs to open one water inlet 11, and the swimming pool cleaning robot can float on the swimming pool water surface or sink to the swimming pool bottom. The swimming pool cleaning robot can control the floating posture of the swimming pool cleaning robot in the water through a floating posture adjustment module, thereby changing the penetration direction and horizontal height of the water inlet 11; wherein, when the swimming pool cleaning robot floats on the swimming pool water surface 3, it can adjust the floating posture to control the water inlet 11 to be close to or face the swimming pool water surface 3; when the swimming pool cleaning robot sinks to the swimming pool bottom, it can adjust the floating posture to control the water inlet 11 to be close to or face the swimming pool bottom.

[0036] The working principle of the present invention is briefly described as follows: In some preferred embodiments of the swimming pool cleaning robot provided by the present invention, the floating posture adjustment module may include a buoyancy adjustment chamber 2 provided on one side of the main body, the buoyancy adjustment chamber 2 may change the buoyancy of one side of the main body 1, and the water inlet 11 may be specifically provided at the bottom of the main body 1;

[0037] The buoyancy regulating chamber 2 can control water injection or drainage in the chamber to increase or decrease the buoyancy of the buoyancy regulating chamber 2, thereby reducing or increasing the buoyancy of the buoyancy regulating chamber 2 in the water; in actual application, the buoyancy regulating chamber 2 can inject an appropriate amount of water into the chamber to reduce the buoyancy of the buoyancy regulating chamber 2, and the swimming pool cleaning robot can sink to the bottom of the swimming pool. When the swimming pool cleaning robot moves at the bottom of the swimming pool in a horizontal posture, the water inlet 11 faces the bottom of the swimming pool. At this time, the swimming pool cleaning robot performs a pool bottom cleaning operation, and the water inlet 11 can more easily inhale dirt deposited on the bottom of the swimming pool;

[0038] When the swimming pool cleaning robot needs to switch from cleaning the pool bottom to cleaning the water surface 3, the swimming pool cleaning robot can rise to the water surface 3 by climbing a wall or the like; during the ascent of the swimming pool cleaning robot, the buoyancy regulating chamber 2 can discharge an appropriate amount of water in the chamber to increase the buoyancy of the buoyancy regulating chamber 2, thereby ensuring that the swimming pool cleaning robot can remain floating after rising to the water surface;

[0039] After the pool cleaning robot floats on the pool water surface 3, the buoyancy regulating chamber 2 can change the buoyancy of the side of the pool cleaning robot provided with the buoyancy regulating chamber 2 by sucking in or discharging an appropriate amount of water into the chamber, while the buoyancy of the other side of the pool cleaning robot remains unchanged. When the buoyancy on both sides of the pool cleaning robot is unequal, the floating posture of the pool cleaning robot in the water tilts, and the side of the pool cleaning robot with relatively greater buoyancy will float upward, while the side of the pool cleaning robot with relatively less buoyancy will sink downward. The pool cleaning robot controls the unequal buoyancy on both sides of the pool cleaning robot through the buoyancy regulating chamber 2, thereby changing the floating posture of the pool cleaning robot. Figure 4 As shown, the buoyancy regulating chamber 2 can control the swimming pool cleaning robot to assume an inclined floating posture, and control the swimming pool cleaning robot to tilt to a position where the water inlet 11 is close to or facing the swimming pool water surface 3. At this time, the swimming pool cleaning robot performs the cleaning operation of the swimming pool water surface 3, and the water inlet 11 can more easily absorb the dirt floating on the swimming pool water surface 3.

[0040] Of course, the above-mentioned buoyancy adjustment chamber 2 is only an optional implementation of the floating posture adjustment module described in the present invention; in some preferred implementations of the present invention, the floating posture adjustment module can also use other existing mechanisms that can change the floating posture of the device in water.

[0041] As can be seen from the above description, the beneficial effects of the present invention are: the swimming pool cleaning robot provided by the present invention has a simple structure, the water inlet 11 occupies a small space inside the swimming pool cleaning robot, and the internal assembly space of the swimming pool cleaning robot can be used to set other functional components (for example, batteries, etc.), thereby improving the performance of the swimming pool cleaning robot;

[0042] In addition, when the operator performs cleaning maintenance on the swimming pool cleaning robot, the operator only needs to clean one water inlet 11, which can shorten the time for the operator to clean the water inlet 11, thereby reducing the use cost of the swimming pool cleaning robot;

[0043] In addition, after the existing swimming pool cleaning robot absorbs dirt in the water, the overall buoyancy of the swimming pool cleaning robot will be changed, resulting in the existing water inlet 11 being unable to approach or face the swimming pool water surface 3 or the swimming pool bottom, thereby affecting the existing swimming pool cleaning robot's ability to absorb and filter dirt; the swimming pool cleaning robot provided by the present invention can adjust the swimming pool cleaning robot's floating posture in real time to ensure that the water inlet 11 is close to or faces the swimming pool water surface 3 or the swimming pool bottom, thereby ensuring the swimming pool cleaning robot's ability to absorb and filter dirt in the water.

[0044] Furthermore, the posture adjustment module includes a buoyancy adjustment chamber 2, which is arranged on one side of the main body 1, and the buoyancy adjustment chamber 2 is used to control the swimming pool cleaning robot to float on the surface of the swimming pool or sink to the bottom of the swimming pool, and / or adjust the floating posture of the swimming pool cleaning robot in the water.

[0045] From the above description, it can be seen that in some preferred embodiments of the present invention, the posture adjustment module may specifically include a buoyancy adjustment chamber 2, which can change the buoyancy of the swimming pool cleaning robot in the water so that the swimming pool cleaning robot floats on the surface of the swimming pool or sinks to the bottom of the swimming pool.

[0046] Specifically, in some preferred embodiments of the present invention, the buoyancy regulating chamber 2 may include a chamber body, a water inlet pump, a water outlet pump, an air inlet pump and an air outlet pump, and the chamber body is connected to the water inlet pump, the water outlet pump, the air inlet pump and the air outlet pump, respectively. In actual application, when the swimming pool cleaning robot needs to reduce its buoyancy in the water to sink from the surface of the swimming pool to the bottom of the swimming pool, the water inlet pump can pump water in the swimming pool into the chamber body, and the air outlet pump discharges the air in the chamber body to increase the density of the chamber body, thereby reducing the buoyancy of the swimming pool cleaning robot;

[0047] The swimming pool cleaning robot may further include a compressed air tank, which is used to spray air downward in a vertical direction, so that the swimming pool cleaning robot floats from the bottom of the swimming pool to the surface of the swimming pool under the action of the spray force; or the swimming pool cleaning robot may include a wall climbing mechanism, which is used to drive the swimming pool cleaning robot to move along the swimming pool wall;

[0048] When the swimming pool cleaning robot needs to increase its buoyancy in the water so as to float to the surface of the swimming pool from the bottom of the swimming pool, the swimming pool cleaning robot can float to the surface of the swimming pool through a compressed air tank or a wall-climbing mechanism. After the swimming pool cleaning robot floats to the surface of the swimming pool, the water in the warehouse body is discharged through the water outlet pump and the air intake pump injects air into the warehouse body, thereby increasing the buoyancy of the warehouse body and allowing the swimming pool cleaning robot to float on the surface of the swimming pool.

[0049] In some other preferred embodiments of the present invention, the buoyancy regulating chamber 2 may also use an existing buoyancy regulating mechanism according to actual use requirements.

[0050] In addition, in some other preferred embodiments of the present invention, the buoyancy adjusting chamber 2 can be further specifically arranged on one side of the main body 1, and the buoyancy adjusting chamber 2 can only change the buoyancy of one side of the swimming pool cleaning robot, while the buoyancy of the other side of the swimming pool cleaning robot remains unchanged, so that the buoyancy on the two opposite sides of the swimming pool cleaning robot is unequal, and the floating posture of the swimming pool cleaning robot in the water tilts, and the side of the swimming pool cleaning robot with relatively larger buoyancy will float upward, and the side of the swimming pool cleaning robot with relatively smaller buoyancy will sink downward, thereby adjusting the floating posture of the swimming pool cleaning robot in the water.

[0051] Furthermore, the water inlet 11 is disposed at the bottom of the main body 1 or at a position close to the bottom on one side of the main body 1 .

[0052] Furthermore, when the swimming pool cleaning robot floats on the swimming pool water surface, the floating posture adjustment module adjusts the posture of the swimming pool cleaning robot, and the swimming pool cleaning robot is inclined at a certain angle to the swimming pool water surface so that the water inlet is close to the swimming pool water surface.

[0053] From the above description, it can be seen that the water inlet 11 can be arranged at the bottom of the main body 1 or at a position close to the bottom of one side of the main body 1. In actual application, when the swimming pool cleaning robot sinks to the bottom of the swimming pool, the swimming pool cleaning robot is in a horizontal posture, and the water inlet 11 can be close to or facing the bottom of the swimming pool; when the swimming pool cleaning robot floats on the surface of the swimming pool, the floating posture adjustment module can control the swimming pool cleaning robot to maintain an inclined posture, and the side of the main body 1 with the water inlet 11 is close to the water surface of the swimming pool.

[0054] In addition, in some other preferred embodiments of the swimming pool cleaning robot provided by the present invention, the water inlet 11 can also be arranged on the side of the bottom of the main body 1 close to the forward direction, and the buoyancy adjustment chamber 2 can be arranged on the side of the main body 1 close to the forward direction; when the swimming pool cleaning robot sinks to the bottom of the swimming pool, the swimming pool cleaning robot is in a horizontal posture at the bottom of the pool, and the water inlet 11 can be close to or facing the bottom of the swimming pool, and the buoyancy adjustment chamber 2 does not need to adjust the floating posture of the swimming pool cleaning robot; when the swimming pool cleaning robot floats on the water surface 3 of the swimming pool, the buoyancy adjustment chamber 2 is arranged on the side close to the water inlet 11, which makes it easier to adjust the floating posture of the swimming pool cleaning robot so that the water inlet 11 is close to or facing the water surface 3 of the swimming pool.

[0055] Furthermore, a water outlet 12 is provided on the main body 1 , and a water flow channel 13 is formed between the water inlet 11 and the water outlet 12 .

[0056] As can be seen from the above description, when the swimming pool cleaning robot is performing cleaning operations, the water inlet 11 sucks in water and dirt in the swimming pool 8, the water and dirt in the swimming pool 8 are filtered through the water flow channel 13, and finally the swimming pool cleaning robot discharges the filtered water from the water outlet 12.

[0057] Among them, in some preferred embodiments of the swimming pool cleaning robot provided by the present invention, a filter can be set in the water flow channel 13, and the filter can filter out dirt in the water and pass through the water flow. The water flow channel 13 filters the dirt in the water of the swimming pool 8 at the filter, and discharges the filtered clean water at the outlet 12.

[0058] Furthermore, the water outlet 12 is disposed on the top of the main body 1 and / or on a side of the main body 1 away from the water inlet 11 .

[0059] In some preferred embodiments of the swimming pool cleaning robot provided by the present invention, the water outlet 12 may be provided at the top of the main body 1. When the swimming pool cleaning robot sinks to the bottom of the swimming pool, the water outlet 12 provided at the top of the main body 1 discharges water upward, so that the water flow provides a downward force on the swimming pool cleaning robot, thereby making the swimming pool cleaning robot perform a more stable bottom cleaning action.

[0060] When the swimming pool cleaning robot floats on the water surface 3 of the swimming pool, in some postures of the swimming pool cleaning robot for cleaning operation of the water surface 3, the water outlet 12 arranged on the top will tilt and sink below the water surface 3, and the water outlet 12 will discharge water into the water, so that the water flow provides thrust to the swimming pool cleaning robot, thereby making it easy for the swimming pool cleaning robot to move in the water under the action of the thrust.

[0061] In some other preferred embodiments of the swimming pool cleaning robot provided by the present invention, the water outlet 12 can also be arranged on a side away from the suction port. When the water outlet 12 discharges water, the water flow generates thrust on the swimming pool cleaning robot, which can push the swimming pool cleaning robot to move in the water toward the side close to the water inlet 11, which is more conducive to the swimming pool cleaning robot to inhale water and dirt during the movement.

[0062] In some other preferred embodiments of the swimming pool cleaning robot provided by the present invention, water outlets 12 are respectively provided on the top of the main body 1 and on the side away from the water inlet 11, and switching devices can be provided on the two water outlets 12 to open one of the water outlets 12 according to actual usage requirements.

[0063] Furthermore, a water pump 4 is included, and the water pump 4 is at least partially located in the water flow channel 13 .

[0064] From the above description, it can be seen that the water pump 4 creates a negative pressure between the water inlet 11, the water flow channel 13 and the water outlet 12. The water pump 4 can help the swimming pool cleaning robot to suck water and dirt in the swimming pool 8 into the water flow channel 13 through the water inlet 11, so as to improve the cleaning efficiency of the swimming pool cleaning robot.

[0065] Furthermore, it also includes a filter 5 , which is arranged in the water flow channel 13 .

[0066] It can be seen from the above description that the water and dirt entering the swimming pool cleaning robot are filtered through the filter 5 .

[0067] Furthermore, it also includes a cleaning device, which is arranged at a position of the main body 1 close to the water inlet 11.

[0068] In some preferred embodiments of the swimming pool cleaning robot provided by the present invention, the cleaning device may be a roller brush 6 (such as Figure 1 As shown), when the swimming pool cleaning robot performs pool bottom cleaning operations, the roller brush 6 can scrub the pool bottom and lift up dirt deposited on the pool bottom to improve the cleaning quality of the pool cleaning robot.

[0069] In some other preferred embodiments of the swimming pool cleaning robot provided by the present invention, a scraper can be provided on the roller brush. In actual application, a motor is provided on the swimming pool cleaning robot to drive the roller brush and the scraper to rotate. The swimming pool cleaning robot can roll the dirt in the water to the water inlet 11 through the scraper, and the scraper drives the water flow to drive the swimming pool cleaning robot to move in the water.

[0070] Furthermore, it also includes a controller and a detection device, both of which are arranged in the main body 1, and the controller is connected to the detection device and the buoyancy regulating chamber 2 respectively.

[0071] From the above description, it can be seen that the detection device can detect at least one of the following information: the floating posture, diving depth, liquid level of the water inlet, etc. of the swimming pool cleaning robot; the controller controls the buoyancy adjustment chamber 2 to adjust the swimming pool cleaning robot to a suitable floating posture according to the detection information of the detector, so as to ensure that when the swimming pool cleaning robot floats on the water surface 3 of the swimming pool, the water inlet 11 is close to or facing the water surface 3 of the swimming pool; when the swimming pool cleaning robot sinks to the bottom of the swimming pool, the water inlet 11 is close to or facing the bottom of the swimming pool.

[0072] Furthermore, the detection device is disposed in the main body 1 at a position close to the water inlet 11 .

[0073] From the above description, it can be seen that arranging the detection device near the water inlet 11 is more conducive to detecting the state of the water inlet 11, thereby controlling the buoyancy adjustment chamber 2 to adjust the posture of the swimming pool cleaning robot to ensure that the water inlet 11 is close to or facing the swimming pool water surface 3 or the bottom of the swimming pool.

[0074] Furthermore, the detection device includes a capacitive liquid level sensor.

[0075] It can be seen from the above description that the capacitive liquid level sensor is used to detect the liquid level at the water inlet, and the circuit part of the capacitive liquid level sensor does not need to be in contact with the liquid, which can simplify the sealing structure of the swimming pool cleaning robot.

[0076] Furthermore, the buoyancy regulating chamber 2 includes a chamber body, a water inlet pump 4 and a water discharge pump 4, and the chamber body is connected to the water inlet pump 4 and the water discharge pump 4 respectively.

[0077] It can be seen from the above description that the water inlet pump 4 can absorb water into the warehouse body, and the water discharge pump 4 can discharge the water in the warehouse body to change the buoyancy of the warehouse body.

[0078] In some preferred embodiments of the swimming pool cleaning robot provided by the present invention, the buoyancy adjustment chamber 2 may further include an exhaust pump and an air intake pump to inject and exhaust air into the chamber.

[0079] Embodiment 1

[0080] Please refer to Figures 1 to 4 , Embodiment 1 of the present invention is: a swimming pool cleaning robot, comprising a main body 1, a floating posture adjustment module, a water pump 4, a filter 5, a detection device, a controller, a driving device 7 and a roller brush 6;

[0081] The main body 1 is provided with a water inlet 11 and a water outlet 12 on opposite sides thereof, and the water inlet 11 is provided at a position close to the bottom of the main body 1 (eg Figure 3 and Figure 4As shown in FIG. 1 , a water flow channel 13 is formed between the water inlet 11 and the water outlet 12, and the water pump 4 and the filter 5 are respectively arranged in the water flow channel 13. The water pump 4 provides negative pressure for the water flow channel 13, so that the swimming pool cleaning robot can inhale water and dirt in the swimming pool 8 through the water inlet 11, and discharge the water filtered by the filter 5 through the water outlet 12, that is, the water flow direction is: water inlet 11-water flow channel 13-filter 5-water outlet 12;

[0082] In the first embodiment, the floating posture adjustment module includes a buoyancy adjustment chamber 2, and the buoyancy adjustment chamber 2 is arranged on one side of the main body 1 close to the water inlet 11; the roller brush 6 is arranged at a position of the main body 1 close to the water inlet 11, and a motor can be arranged in the main body 1 to drive the roller brush 6 to rotate; the driving device 7 is arranged on the main body 1, and in the first embodiment, the driving device 7 is used to drive the main body 1 to move on the bottom of the swimming pool or drive the main body 1 to climb the wall of the swimming pool 8.

[0083] The controller and the detection device are both arranged in the main body 1, and the controller is connected to the detection device and the buoyancy regulating chamber 2 respectively;

[0084] In the first embodiment, the detection device includes a capacitive liquid level sensor, and the capacitive liquid level sensor is arranged in the main body 1 near the water inlet 11. In actual application, the detection device detects the liquid level information at the water inlet 11 and sends the liquid level information to the controller. The controller controls the buoyancy adjustment chamber 2 to work according to the floating posture, diving depth, liquid level of the water inlet and other information of the swimming pool cleaning robot.

[0085] In the first embodiment, the buoyancy regulating chamber 2 includes a chamber body, a water inlet pump, a water outlet pump, an air inlet pump and an air outlet pump, the chamber body is connected to the water inlet pump, the water outlet pump, the air inlet pump and the air outlet pump respectively, and the driving device 7 includes a suction cup provided at the bottom of the main body 1 and a roller provided on the main body 1, the swimming pool cleaning robot can realize the wall climbing function through the suction cup and the roller, so as to drive the swimming pool cleaning robot to be adsorbed on the swimming pool wall and move along the swimming pool wall;

[0086] When the swimming pool cleaning robot is cleaning the pool bottom, the water inlet pump of the buoyancy adjustment chamber 2 can inject water into the chamber body, and the air outlet pump can discharge the air in the chamber body to reduce the buoyancy of the chamber body. When a proper amount of water is injected into the chamber body, the swimming pool cleaning robot can sink to the bottom of the swimming pool, and the swimming pool cleaning robot is in a horizontal state at the bottom of the water (such as Figure 3 As shown), the water inlet 11 is close to the bottom of the swimming pool. At this time, the driving device 7 drives the swimming pool cleaning robot to move on the bottom of the swimming pool. The roller brush 6 rotates to lift up the dirt settled on the bottom of the swimming pool. The water inlet 11 sucks water from the swimming pool 8 and the dirt settled on the bottom of the swimming pool. The water and the dirt pass through the filter 5, the filter 5 filters the dirt, and the water outlet 12 discharges the filtered water.

[0087] In the first embodiment, when the swimming pool cleaning robot completes the pool bottom cleaning operation, the swimming pool cleaning robot moves along the pool wall 8 through the driving device 7 and rises to the swimming pool water surface 3. At this time, the buoyancy adjustment chamber 2 can discharge an appropriate amount of water through the water outlet pump, and the air intake pump injects air into the chamber to increase the buoyancy of the swimming pool cleaning robot, thereby ensuring that the swimming pool cleaning robot can float on the swimming pool water surface 3 after rising.

[0088] When the swimming pool cleaning robot performs a water surface 3 cleaning operation, the buoyancy regulating chamber 2 can further control water injection or drainage in the chamber to adjust the buoyancy of one side of the swimming pool cleaning robot. When the buoyancy of the two sides of the swimming pool cleaning robot is different, the floating posture of the swimming pool cleaning robot in the water will change and tilt, and the side with greater buoyancy will float up and the side with less buoyancy will sink. According to the water level information of the water inlet 11 detected by the capacitive liquid level sensor, the controller controls the buoyancy regulating chamber 2 to adjust the swimming pool cleaning robot to a state where the water inlet 11 is close to the swimming pool water surface 3.

[0089] In addition, it is easy to understand that in the first embodiment, the buoyancy adjustment chamber 2 of the swimming pool cleaning robot controls the filling or drainage of water in the chamber, so that when the swimming pool cleaning robot is tilted at a certain angle to the water surface in the water, the water inlet 11 can be just facing the swimming pool water surface (such as Figure 4 shown);

[0090] At this time, the swimming pool cleaning robot moves on the swimming pool water surface 3, the water inlet 11 sucks in the water in the swimming pool 8 and the dirt on the bottom of the pool, the water and the dirt in the swimming pool 8 pass through the filter 5, the filter 5 filters the dirt, and the water outlet 12 discharges the filtered water.

[0091] Embodiment 2

[0094] When the swimming pool cleaning robot performs a water surface 3 cleaning operation, the swimming pool cleaning robot is in an inclined floating posture in the water, so that the water inlet 11 is close to or facing the swimming pool water surface.

[0095] Embodiment 3

[0096] The third embodiment of the present invention is an improvement on the water inlet 11 based on the first embodiment. In the third embodiment: the water inlet 11 can also be arranged on one side of the main body 1;

[0097] When the buoyancy regulating chamber 2 controls the swimming pool cleaning robot to float on the swimming pool water surface 3, the buoyancy regulating chamber 2 can adjust the floating posture of the swimming pool cleaning robot in the water to ensure that the water inlet 11 is close to or facing the swimming pool water surface 3. At this time, the swimming pool cleaning robot performs the cleaning operation on the swimming pool water surface 3, and the water inlet 11 is easy to inhale the dirt floating on the swimming pool water surface 3;

[0098] The buoyancy regulating chamber 2 can inject a proper amount of water into the chamber to reduce the buoyancy of the buoyancy regulating chamber 2, thereby controlling the swimming pool cleaning robot to sink to the bottom of the water, and controlling the swimming pool cleaning robot to tilt toward the side where the water inlet 11 is opened. The buoyancy regulating chamber 2 adjusts the posture of the swimming pool cleaning robot to ensure that the water inlet 11 is close to or facing the bottom of the swimming pool. At this time, the swimming pool cleaning robot performs the cleaning operation of the swimming pool surface 3, and the water inlet 11 is easy to suck in the dirt settled to the bottom of the swimming pool;

[0099] When the swimming pool cleaning robot floats from the bottom of the swimming pool to the surface of the water, the buoyancy adjustment chamber 2 can inhale or discharge air, thereby adjusting the buoyancy of the swimming pool cleaning robot.

[0100] Embodiment 4

[0101] Embodiment 4 of the present invention is an improvement on the driving device 6 based on embodiment 1. In this embodiment 4: the driving device 6 includes a roller arranged on the main body 1 and a compressed air tank arranged in the main body 1, and the compressed air tank is used to spray air downward in a vertical direction so that the swimming pool cleaning robot floats from the bottom of the swimming pool to the surface of the swimming pool under the action of the spray force.

[0102] In addition, the compressed air tank can also be used to inject compressed air into the buoyancy adjustment chamber 2, so that the buoyancy of the swimming pool cleaning robot is reduced and then floats up.

[0103] In summary, the swimming pool cleaning robot provided by the present invention has a simple structure, the water inlet 11 occupies little space inside the swimming pool cleaning robot, and the internal assembly space of the swimming pool cleaning robot can be used to set other functional components (for example, batteries, etc.), thereby improving the performance of the swimming pool cleaning robot;

[0104] In addition, when the operator performs cleaning maintenance on the swimming pool cleaning robot, the operator only needs to clean one water inlet 11, which can shorten the time for the operator to clean the water inlet 11, thereby reducing the time cost that the operator needs to pay when using the swimming pool cleaning robot;

[0105] In addition, after the existing swimming pool cleaning robot absorbs dirt in the water, the overall buoyancy of the swimming pool cleaning robot will be changed, resulting in the existing water inlet 11 being unable to face the swimming pool water surface 3 or the swimming pool bottom, thereby affecting the existing swimming pool cleaning robot's ability to absorb and filter dirt; the swimming pool cleaning robot provided by the present invention can adjust the swimming pool cleaning robot's floating posture in real time to ensure that the water inlet 11 faces the swimming pool water surface 3 or the swimming pool bottom, thereby ensuring the swimming pool cleaning robot's ability to absorb and filter dirt in the water.

[0106] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
