One end of the second flow channel is connected to the outside, and the other end of the second flow channel is connected to the cavity of the shell. The interiors of the first flow channel and the second flow channel are of equal width, and the first flow channel and the second flow channel are symmetrical about the middle of the main body.

[0007] Furthermore, the inlet of the first flow channel and the inlet of the second flow channel are far away from each other relative to the middle of the main body, and the outlet of the first flow channel and the outlet of the second flow channel are close to each other relative to the middle of the main body.

[0011] The maximum distance from the outer edge of the first flow channel outlet to the outer edge of the second flow channel outlet is L2, and L2 is 0.06L to 0.2L;

[0012] The inner width of the first flow channel and the second flow channel is L3, and L3 is 0.02L to 0.1L;

[0013] The height of the first flow channel and the second flow channel is H1, and H1 is 0.1H to 0.7H;

[0014] The width of the first flow channel and the second flow channel is W1, and W1 is 0.3W-0.8W.

When the cleaning mechanism is in operation, water can be sucked into the body of the swimming pool cleaning robot according to the trajectory of the first flow channel and the second flow channel. Compared with the design in the related art where the first flow channel and the second flow channel are not arranged, the present invention can effectively prevent the internal turbulence by adding the design of the first flow channel and the second flow channel, thereby improving the energy utilization efficiency, increasing the cleaning and recycling efficiency of the swimming pool robot, and improving the problem of poor garbage cleaning and recycling efficiency of the swimming pool robot in the related art.

[0023] 2.

[0024] 3. The swimming pool cleaning robot of the present invention is provided with a guide cover that cooperates with the first flow channel and the second flow channel. When water flows into the robot from the outlets of the first flow channel and the second flow channel, the water flow can be effectively diverted under the action of the guide cover, thereby evenly moving to the first cleaning component and the second cleaning component on both sides, thereby preventing garbage from gathering on one side of the filter and causing blockage.

[0030] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] Reference Figure 1 and Figure 2 A swimming pool cleaning robot with a suction flow channel includes a main body 1, a cleaning mechanism 2 disposed in the main body 1, and a moving mechanism 3 disposed below the main body 1. The main body 1 includes a shell 11 and a first flow channel 12 and a second flow channel 13 disposed in the shell 11. The middle of the shell 11 has a cavity, and the cavity is used to accommodate and install the first flow channel 12, the second flow channel 13 and the cleaning mechanism 2.

[0033] Specifically, the first flow channel 12 has two ends, one end of the first flow channel 12 is located below the housing 11 and communicates with the outside, and the other end of the first flow channel 12 is located in the cavity of the housing 11 and communicates with the cavity of the housing 11. Similarly, the second flow channel 13 has two ends, one end of the second flow channel 13 is located below the housing 11 and communicates with the outside, and the other end of the second flow channel 13 is located in the cavity of the housing 11 and communicates with the cavity of the housing 11. The interior of the first flow channel 12 is of equal width, and the interior of the second flow channel 13 is of equal width, and the first flow channel 12 and the second flow channel 13 are symmetrical about the middle of the main body 1.

[0034] At the same time, the inlet of the first flow channel 12 and the inlet of the second flow channel 13 are far away from each other relative to the middle of the main body 1, and the outlet of the first flow channel 12 and the outlet of the second flow channel 13 are close to each other relative to the middle of the main body 1. That is, the first flow channel 12 extends from a side away from the middle of the main body 1 to a direction close to the middle of the main body 1, and the second flow channel 13 also extends from a side away from the middle of the main body 1 to a direction close to the middle of the main body 1. The first flow channel 12 and the second flow channel 13 have an arc for transition. Taking the first flow channel 12 as an example, the first flow channel 12 has a first arc segment and a second arc segment, and the first arc segment is connected to the second arc segment. Similarly, the second flow channel 13 also has a first arc segment and a second arc segment that are connected to each other.

[0035] In order to obtain better energy utilization, the present invention sets the size of the first flow channel 12 and the second flow channel 13 based on the size of the main body 1. Specifically, the total length of the main body 1 is L, the width of the main body 1 is W, and the height of the main body 1 is H. The maximum distance from the outer edge of the inlet of the first flow channel 12 to the outer edge of the inlet of the second flow channel 13, that is, the distance from the end of the inlet of the first flow channel 12 away from the inlet of the second flow channel 13 to the end of the inlet of the second flow channel 13 away from the inlet of the first flow channel 12 is L1, and L1 is 0.3L~0.7L. By setting L1 in this way, an appropriate distance can be maintained between the inlets of the first flow channel 12 and the second flow channel 13, thereby preventing the inlets of the first flow channel 12 and the second flow channel 13 from competing and losing the suction efficiency.

[0036] The maximum distance from the outer edge of the outlet of the first flow channel 12 to the outer edge of the outlet of the second flow channel 13, that is, the distance from one end of the outlet of the first flow channel 12 away from the outlet of the second flow channel 13 to one end of the outlet of the second flow channel 13 away from the outlet of the first flow channel 12 is L2, and L2 is 0.06L to 0.2L. By setting L2 in this way, the outlets of the first flow channel 12 and the second flow channel 13 are separated by a suitable distance, so that the water flow smoothly enters the interior of the swimming pool cleaning robot and facilitates subsequent diversion.

[0037] The internal width of the first flow channel 12 and the second flow channel 13 is L3, and L3 is 0.02L to 0.1L. By setting L3 in this way, it is avoided that the internal width is too small to cause too much water flow resistance to affect the work efficiency, or the internal width is too large to form turbulence entering the robot and affecting cleaning, that is, the internal width of the first flow channel 12 and the second flow channel 13 is an appropriate value so that turbulence is not formed under the premise of achieving small resistance.

[0038] The height of the first flow channel 12 and the second flow channel 13, that is, the distance from the lowest end point to the highest end point of the first flow channel 12 or the second flow channel 13 is H1, and H1 is 0.1H~0.7H; by setting H1 in this way, the appropriate flow channel height can be maintained to avoid the formation of turbulence while ensuring the distance between the first flow channel 12 and the second flow channel 13 and the top of the shell 11, thereby reducing the flow channel loss caused by the backflow caused by the water flow in the first flow channel 12 and the second flow channel 13 impacting the top of the shell 11.

[0039] The width of the first flow channel 12 and the second flow channel 13 is W1, which is the outer width and is 0.3W to 0.8W. By setting W1 in this way, it is possible to avoid the situation where the width of the first flow channel 12 or the second flow channel 13 is too small to increase resistance, or the width is too large to form turbulence.

[0040] In this embodiment, in order to obtain the best energy utilization rate, L1 = 0.5L, L2 = 0.1L, L3 = 0.05L, H1 = 0.4H, W1 = 0.6W. When the values ​​of the first flow channel 12 and the second flow channel 13 are set under this condition, the water flow suction efficiency of the swimming pool robot is the highest, that is, the garbage recovery rate is the highest. By adding the design of the first flow channel 12 and the third flow channel 13, turbulence can be effectively prevented from occurring inside, thereby improving the energy utilization efficiency and increasing the efficiency of the cleaning and recovery work of the swimming pool robot.

[0041] In order to clean the garbage in the water flow, the cleaning mechanism 2 includes a filter screen 21 arranged in the middle of the cavity of the shell 11. The upper end of the filter screen 21 is fixedly connected to the upper part of the cavity of the shell 11, and the lower end of the filter screen 21 is fixedly connected to the lower part of the cavity of the shell 11. The filter screen 21 divides the cavity of the shell 11 into a first area, a second area and a collection area. The collection area is located between the first area and the second area. A first cleaning component 22 is arranged in the first area, and a second cleaning component 23 is arranged in the second area.

[0042] The outlets of the first flow channel 12 and the second flow channel 13 are located in the collection area. By setting the filter 21 in this way, after the water flow in the first flow channel 12 and the second flow channel 13 enters the collection area, it will pass through the filter 21 to the first area and the second area, and the garbage in the water flow will be blocked by the filter 21 and remain in the collection area. The two ends of the cavity of the shell 11 are respectively provided with water spraying ports located in the first area and the second area, and the water flow flows out from the water spraying ports after being filtered by the filter 21.

[0043] The first cleaning assembly 22 includes a first motor 221 disposed in the first area, the first motor 221 is fixed in the first area, the output shaft of the first motor 221 faces the water outlet of the first area, the output shaft of the first motor 221 is coaxially mounted with a propeller, and the propeller can be driven to rotate by starting the first motor 221; similar to the first cleaning assembly 22, the second cleaning assembly 23 includes a second motor 231 disposed in the second area, the second motor 231 is fixed in the second area, the output shaft of the second motor 231 faces the water outlet of the second area, the output shaft of the second motor 231 is coaxially mounted with a propeller, and the propeller can be driven to rotate by starting the second motor 231. When the first motor 221 and the second motor 231 are started to drive the corresponding propellers to rotate, the flow can be driven to pass through the first flow channel 12 and the second flow channel 13 into the collection area, and then be ejected from the water outlet after being filtered by the filter 21.

[0044] In addition, the first cleaning assembly 22 further includes a first water pump 222 disposed on the first motor 221, and the second cleaning assembly 23 further includes a second water pump 232 disposed on the second motor 231. The first motor 221 is used to drive the first water pump 222 to operate, and the second motor 222 is used to drive the second water pump 232 to operate. By operating one of the first motor 221 and the second motor 231, the corresponding first water pump 222 or the second water pump 232 can be driven to operate, so that water flows from the first flow channel 12 and

[0045] The water enters the inlet of the second flow channel 13, and after being filtered by the filter screen 21, the water is ejected from the first area water jet or the second area water jet. The reaction force of the water ejected from the first area water jet or the second area water jet is used to drive the pool cleaning robot.

[0046] In order to guide the water flow in the first flow channel 12 and the second flow channel 13, the cleaning mechanism 2 also includes a guide cover 24. Specifically, the guide cover 24 is located above the collection area, the guide cover 24 is fixed to the inner wall of the shell 11, the guide cover 24 faces the first flow channel 12 and the second flow channel 13, and the outlets of the first flow channel 12 and the second flow channel 13 face the guide cover 24. When the water flows into the collection area through the first flow channel 12 and the second flow channel 13, the water flow in the first flow channel 12 and the second flow channel 13 will be directed to the guide cover 24, and under the action of the guide cover 24, it will flow evenly in all directions, avoiding the accumulation of garbage on one side of the filter screen 21 and causing local blockage, thereby effectively delaying the time of the pool robot being shut down due to local blockage of the filter screen 21.

[0047] The moving mechanism 3 is used to drive the swimming pool robot to move, and the moving mechanism 3 includes a plurality of wheels rotatably connected to the main body 1 .

[0048] The working principle of the swimming pool cleaning robot with a suction flow channel of the present invention is as follows: the first cleaning component 22 or the second cleaning component 23 is in operation, and the water flow in the swimming pool enters the collection area after passing through the first flow channel 12 and the second flow channel 13 under the action of the first cleaning component 22 or the second cleaning component 23 and is ejected from the water spray port, and the garbage in the water flow will be blocked by the filter 21 and remain in the collection area. By setting the first flow channel 12 and the second flow channel 13, the water flow can be sucked into the swimming pool cleaning robot body according to the trajectory of the first flow channel 12 and the second flow channel 13, and the energy utilization efficiency is higher, thereby increasing the efficiency of the cleaning and recycling work of the swimming pool robot.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
