[0021] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0022] In the related art, a pool cleaning robot generally has two sets of wheels, one in front and one in back, and each set of wheels is connected by a long axis. The long axis of one set of wheels is fixed to the shell, and the other set of wheels uses the wheel on one side as a fulcrum, and a wheel on the other side can move forward and backward along the direction of the shell. This can cause the robot's direction of travel to shift, thereby achieving the robot's steering. However, the wheels are prone to jamming when sliding in the grooves fixed on the shell, so that the robot cannot turn smoothly. At the same time, since the distance between the front and rear wheels is fixed, the robot's steering angle is also fixed, and the robot's steering angle cannot be adjusted according to the shape and size of the swimming pool.

[0023] For the above situation, please see Figure 1 The present application provides a swimming pool cleaning machine 1 , which includes a housing 10 , a first pipe 20 , a second pipe 30 and a driving assembly 50 .

[0024] The housing 10 has a housing chamber 11 and a water inlet (not shown in the figure) connected to the housing chamber 11; the first pipe 20 is arranged in the housing chamber 11; the second pipe 30 is arranged in the housing chamber 11, and the second pipe 30 includes a first part 31 and a second part 32 that are connected to each other, the first part 31 is connected to the first end of the first pipe 20, and is rotatably connected to the first pipe 20 around the central axis of the first pipe 20, the first part 31 and the second part 32 are arranged at an angle, and the second part 32 has a water outlet 321, which is connected to the outside of the housing chamber 11; the driving assembly 50 is arranged in the housing chamber 11, the driving assembly 50 is connected to the water inlet and the second end of the first pipe 20, and the driving assembly 50 is used to extract liquid through the water inlet, and transport the liquid to the water outlet 321 through the first pipe 20 and the second pipe 30, and spray it out through the water outlet 321, so that the swimming pool cleaning machine 1 moves in a direction opposite to the direction of the water outlet 321.

[0025] Specifically, the pool cleaning machine 1 is used to clean the environment in the pool, so the liquid extracted from the driving assembly 50 is water. The driving assembly 50 may include a water pump for absorbing water, and the water is transported from the water inlet to the water outlet 321 by the water pump. The pool cleaning machine 1 can use the reaction force of the water flow discharged from the water outlet 321 to drive the pool cleaning machine 1 to move forward. The first part 31 and the second part 32 of the second pipe 30 are arranged at an angle, so when the first part 31 and the first pipe 20 rotate around the central axis of the first pipe 20, the second part 32 will also rotate with the first part 31, so that the direction of the water outlet 321 changes, and the direction of the water outlet 321 is opposite to the moving direction of the pool cleaning machine 1, so that the moving direction of the pool cleaning machine 1 can be changed.

[0026] It should be noted that the swimming pool cleaning machine 1 in the embodiment of the present application transports water from the water inlet to the water outlet 321 and sprays it out through the driving component 50, and the water flow sprayed from the water outlet 321 provides thrust for advancement. At the same time, a rotatable second pipe 30 is provided, and the direction of the water outlet 321 on the second pipe 30 is changed by the rotation between the second pipe 30 and the first pipe 20, so that the direction of the water outlet 321 can be changed, thereby changing the thrust direction of the water flow on the swimming pool cleaning machine 1, so as to change the travel direction of the swimming pool cleaning machine 1, thereby increasing the cleaning coverage of the swimming pool cleaning machine 1, and achieving the purpose that the swimming pool cleaning machine 1 can adapt to a variety of swimming pools of different shapes and sizes. The steering function of the swimming pool cleaning machine 1 is simple to operate, has a wide range of applications, and is not prone to failure.

[0027] It should also be noted that, in the second pipe 30, when the water flows from the first part 31 to the second part 32, since the first part 31 and the second part 32 are arranged at an angle, the water flowing out of the first part 31 will be forced to deflect and flow toward the second part 32, thereby reducing the kinetic energy of the water flow, slowing down the travel speed of the pool cleaning machine 1, thereby increasing the cleaning time of the pool cleaning machine 1 and achieving a better cleaning effect of the pool cleaning machine 1. The embodiment of the present application does not specifically limit the angle range between the first part 31 and the second part 32, for example, the angle between the first part 31 and the second part 32 can be 30°, 45°, 60°, etc., and the connection between the first part 31 and the second part 32 is sealed to prevent the connection between the first part 31 and the second part 32 from being exposed to water and affecting the normal operation of the pool cleaning machine 1.

[0028] It should be noted that in the related art, many swimming pool cleaning machines 1 realize the straight-moving and turning functions of the swimming pool cleaning machine 1 by means of path planning in advance or identification control by electronic components, but this will add a complex control system and steering system to the swimming pool cleaning machine 1, which is costly. In the embodiment of the present application, the swimming pool cleaning machine 1 realizes the forward movement function by the reaction force of the water flow, and realizes the steering function by the rotation of the second pipe 30, which is not only low in cost but also simple in structure.

[0029] See also Figure 2-Figure 3 In some embodiments of the present application, the pool cleaning machine 1 further includes a limiting portion 41 and a limiting member 42, wherein the limiting portion 41 is disposed on one of the first portion 31 and the first pipe 20; the limiting member 42 is disposed on the other of the first portion 31 and the first pipe 20, and the limiting member 42 is used for engaging with the limiting portion 41; wherein a plurality of limiting portions 41 are disposed, and the plurality of limiting portions 41 are arranged at intervals around the central axis of the first pipe 20.

[0030] It can be understood that the first part 31 is connected to the first pipe 20 for rotation around the central axis of the first pipe 20. When the limiting member 42 is engaged with the limiting portion 41, the first part 31 and the first pipe 20 are in a limited state, so that when water flows into the first pipe 20 and the second pipe 30, the first part 31 and the first pipe 20 will not rotate relative to each other.

[0031] It should be noted that there are multiple limiting portions 41. Taking the case where there is one limiting member 42, and the limiting portion 41 is arranged on the first part 31, and the limiting member 42 is arranged on the first pipe 20 as an example, when the first part 31 just starts to rotate, one limiting portion 41 on the first part 31 is separated from the limiting member 42 on the first pipe 20; when the first part 31 finishes rotating, another limiting portion 41 on the first part 31 is engaged with the limiting member 42 on the first pipe 20. At this time, the relative position between the second pipe 30 and the first pipe 20 changes, and the second pipe 30 and the first pipe 20 are still in a limited state. Similarly, it can be known that, taking the case where there is one limiting member 42, the limiting portion 41 is provided on the first pipe 20, and the limiting member 42 is provided on the first part 31 as an example, when the first part 31 just starts to rotate, the limiting member 42 on the first part 31 is separated from one limiting portion 41 on the first pipe 20; when the first part 31 finishes rotating, the limiting member 42 on the first part 31 is engaged with another limiting portion 41 on the first pipe 20.

[0032] It should also be noted that the multiple limit portions 41 are evenly spaced, that is, the distance and angle between any two adjacent limit portions 41 are the same, so that the angle adjustment of the first part 31 is simpler and clearer. For example, when the angle between any two adjacent limit portions 41 is 30°, the rotation angle of the first part 31 from the start to the end of the rotation is an integer multiple of 30°, and the rotation angle of the first part 31 can be 30°, 60°, 90°, etc.

[0033] For further information, see Figure 2 In some embodiments of the present application, the limiting portion 41 is a groove arranged on the inner wall of the first part 31, and the multiple grooves are arranged around the central axis of the first pipe 20; the limiting member 42 is a block arranged on the outer wall of the first pipe 20, and the block is engaged with the groove.

[0034] It can be understood that the groove is set on the inner wall of the first part 31, and the block is set on the outer wall of the first pipe 20, so the first part 31 is sleeved on the first pipe 20, and by rotating the first part 31, the block on the outer wall of the first pipe 20 can slide in different grooves.

[0035] Furthermore, in some embodiments of the present application, the number of the limiting members 42 is the same as the number of the limiting portions 41 , and the plurality of limiting members 42 and the plurality of limiting portions 41 are evenly spaced and arranged around the central axis of the first pipe 20 .

[0036] It should be noted that there are multiple limiters 42 and limit portions 41, and the number of the two is the same. Taking the limit portion 41 being arranged on the first pipe 20 and the limiter 42 being arranged on the first part 31 as an example, the limiter 41 and the limiter 42 are evenly spaced around the central axis of the first pipe 20, so each limiter 42 can be engaged with a limiter 41. After the first part 31 rotates, although the position of each limiter 42 changes, each limiter 42 can still be engaged with a limiter 41, thereby strengthening the limiting effect between the first pipe 20 and the second pipe 30 and reducing the occurrence of accidental rotation between the second pipe 30 and the first pipe 20.

[0037] For further information, see Figure 2 In some embodiments of the present application, a plurality of limiting members 42 are provided, and the number of limiting portions 41 is greater than the number of limiting members 42 .

[0038] It is understandable that there are also multiple limiters 42, so that the limiter 42 can strengthen the limiter effect on the first pipe 20 and the second pipe 30. At the same time, when the number of limiters 41 is greater than the number of limiters 42, that is, after the first part 31 rotates a certain angle, the limiter 42 can be engaged with any of the limiters 41, and the rotation angle between the first part 31 and the first pipe 20 can be unlimited, so that the number of limiters 41 is specifically set according to actual needs. Among them, the embodiment of the present application does not limit the specific arrangement of the limiters 41 and the limiters 42, and the specific arrangement of the limiters 41 and the limiters 42 can be the same, for example, the limiters 41 and the limiters 42 can be evenly spaced; of course, the specific arrangement of the limiters 41 and the limiters 42 can also be different, for example, the limiters 41 are evenly spaced, and the limiters 42 are unevenly spaced.

[0039] In addition, in some embodiments, the number of the limiting portions 41 may be an integer multiple of the number of the limiting members 42. For example, if the number of the limiting portions 41 is m1 and the number of the limiting members 42 is m2, m1=n*m2 (n is an integer), wherein the m1 limiting portions 41 are divided into n groups, and the number of the limiting portions 41 in each group is the same as the number of the limiting members 42, and the arrangement positions of the limiting portions 41 in each group are the same as the arrangement positions of the limiting members 42, thereby ensuring that after the first portion 31 rotates a certain angle relative to the first pipe 20, even if the position of the limiting member 42 changes, each limiting member 42 can still be engaged with the corresponding limiting portion 41, and the rotation angle of the second pipe 30 can also be adjusted according to actual conditions. For example, when there are two limiting members 42, the limiting portions 41 may be 4, 6, 8, etc.; and when there are three limiting members 42, the limiting portions 41 may be 6, 9, 12, etc.

[0040] See also Figure 3 In some embodiments of the present application, the driving assembly 50 includes a motor 51 and an impeller 52 , the motor 51 is electrically connected to the impeller 52 , and the impeller 52 is disposed in the first pipeline 20 .

[0041] It should be noted that the motor 51 can drive the impeller 52 to rotate, thereby sucking the liquid from the water inlet, and then transporting the liquid to the water outlet 321 through the first pipe 20 and the second pipe 30, and spraying it out through the water outlet 321. Among them, the impeller 52 can convert mechanical energy into kinetic energy, and transport the liquid through the centrifugal force generated when the impeller 52 rotates. The high-speed rotation of the impeller 52 drives the water flow to rotate, and the liquid is thrown out of the impeller 52 under the action of the centrifugal force, and then transmitted through the first pipe 20 and the second pipe 30, and sprayed out through the water outlet 321.

[0042] See also Figure 3 In some embodiments of the present application, the swimming pool cleaning machine 1 further includes a pipe outer cover 60 , which is sleeved on the second pipe 30 , and the pipe outer cover 60 is rotatably connected to the shell 10 around the central axis of the first pipe 20 .

[0043] Specifically, the pipeline outer cover 60 is sleeved on the second pipeline 30 , which can protect the second pipeline 30 , reduce the damage of the second pipeline 30 caused by external foreign objects, and extend the service life of the second pipeline 30 .

[0044] Furthermore, in some embodiments of the present application, a plurality of angle markings (not shown in the figure) are provided on one side of the shell 10 close to the pipe outer cover 60, and an indicator arrow (not shown in the figure) is provided on the pipe outer cover 60, and the indicator arrow is set toward the angle marking, and the indicator arrow is used to indicate the rotation angle of the pipe outer cover 60 and the second pipe 30.

[0045] It should be noted that when the second pipe 30 and the pipe cover 60 rotate together at a certain angle, the indicator arrow on the pipe cover 60 will point to the corresponding angle mark on the housing 10. For example, when the indicator arrow on the pipe cover 60 faces 0°, water flows out from the water outlet 321 of the second pipe 30, and the pool cleaning machine 1 moves forward in a straight line under the impetus of the water flow. When the second pipe 30 rotates at a certain angle, the direction of the water outlet 321 changes, and the water flow provides the pool cleaning machine 1 with thrust for both forward movement and turning. At this time, the pool cleaning machine 1 will deflect at a certain angle while moving forward, and as the rotation angle of the second pipe 30 increases from small to large, the deflection angle of the pool cleaning machine 1 will also change slowly from small to large when moving forward.

[0046] Furthermore, in some embodiments of the present application, the angle range of the angle mark is 0°-90°.

[0047] It can be understood that the direction of the water outlet 321 is opposite to the travel direction of the pool cleaning machine 1, that is, the water outlet 321 of the second pipe 30 sprays water, and the pool cleaning machine 1 moves forward under the reaction force of the water flow. In order to increase the cleaning coverage of the pool cleaning machine 1, the angle of adjustment of the pool cleaning machine 1 each time can be smaller, so that the deflection angle of the pool cleaning machine 1 is also smaller, so that the second running route of the pool cleaning machine 1 is less spaced from the first running route, thereby the rotation angle range between the second pipe 30 and the first pipe 20 can be 0°-90°, that is, the angle range of the angle mark is 0°-90°.

[0048] In some embodiments of the present application, a connection between the first pipe 20 and the first part 31 is sealed.

[0049] It is understandable that the connection between the first pipe 20 and the first part 31 is sealed, so that the water flow in the first pipe 20 can smoothly enter the second pipe 30, preventing the connection between the first pipe 20 and the first part 31 from being exposed to water and affecting the normal operation of the swimming pool cleaning machine 1.

[0050] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, it is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationships in the drawings are only used for illustrative purposes and cannot be understood as limitations on this application. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0051] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
