[0002] The underwater cleaning robot used in swimming pools cleans the garbage at the bottom of the pool by sucking the sewage to be filtered at the bottom of the pool into the robot, filtering the sewage and discharging it out of the body. The robot obtains the moving force of the body at the bottom of the pool by discharging the filtered water.

[0003] However, existing underwater cleaning robots can only move in a single direction, so they can only clean a fixed area of the pool bottom once. If automatic comprehensive cleaning is required, the robot needs to be moved manually in different directions or positions, which is time-consuming and labor-intensive. Summary of the Invention

[0014] As a further improvement of the present invention, the corresponding edges of the cover shell and the base are both provided with depressions to enclose a mounting opening for fixing the water diversion channel.

[0015] As a further improvement of the present invention, a baffle is provided on the travel side of the water suction port of the base; the baffles are symmetrically distributed, and the spacing between the baffles on opposite sides tends to decrease from far to near.

[0016] As a further improvement of the present invention, the sensing module includes a controller, a magnetic part and a Hall sensor; the magnetic part is installed on the walking wheel; the Hall sensor is installed inside the base close to the walking wheel; the Hall sensor corresponds to the magnetic part to sense the moving state of the fuselage; the controller is connected to the Hall sensor, and the controller is connected to the water absorption module.

[0019] As a further improvement of the present invention, a handle is installed at the rear end of the cover shell.

[0020] Compared with the existing technology, the beneficial effect of the present invention is that: by setting a two-way water diversion channel and a water absorption module that can be reversed, it is ensured that when the water discharged by the water absorption module is discharged from the front side of the water diversion channel, the fuselage will retreat, and when the water discharged by the water absorption module is discharged from the rear side of the water diversion channel, the fuselage will move forward; thereby ensuring that the fuselage can move back and forth to clean the bottom of the pool.

[0022] In addition, a sensing module is set on the body, so that when the robot encounters an obstacle or hits the pool wall, and the forward (or backward) force is insufficient to overcome the obstacle, the walking wheels stop moving, and the controller controls the motor to rotate in the opposite direction. In this way, the robot can move in the opposite direction of its original movement, break away from the obstacle or pool wall, and move in the other direction to clean the pool in the other direction.

DETAILED DESCRIPTION

[0035] Specific embodiment 1: Please refer to Figures 1-9 An underwater automatic cleaning robot includes a body, a water absorption module 60, a filter 70, a water diversion channel 80 and walking wheels 40.

[0036] The body includes a cover 10 and a base 20. The cover 10 and the base 20 are connected to each other up and down to form a hollow installation chamber. The corresponding edges of the cover 10 and the base 20 are both recessed to form an installation opening for the fixed installation of the water diversion channel 80.

[0037] The water channel 80 is located within the fuselage. It is a hollow pipe, with both ends nestled within the aforementioned mounting openings for secure installation. Water channel 80 has water outlets 11 at either end, each rotatably connected to a flap that is normally closed. Water channel 80 connects the interior of the fuselage with the exterior, enabling drainage.

[0038] The bottom of the base 20 is provided with a water inlet 23, which is rotatably connected to a water suction flap, which is in a normally closed state. The water suction module 60, the filter module and the water diversion channel 80 are all located in the installation chamber, so that the installation chamber is in a negative pressure environment during operation to absorb water.

[0039] like Figure 2 As shown, the running wheels are arranged on both sides of the fuselage, and their moving direction is parallel to the drainage direction of the water diversion channel 80.

[0040] like Figure 2 As shown, two front and rear guide wheels 50 are provided on the bottom surface of the base 20; the guide wheels 50 are rotatably connected to the body so as to be able to make slight deflection movements, so that when the robot moves forward or backward, the new walking path is different from the original walking path, ensuring that after multiple reciprocating movements, the cleaning area can cover the entire pool bottom.

[0041] like Figure 2 As shown, a barrier bar is provided on the travel side of the water suction port 23 of the base 20 ; the barrier bars are symmetrically distributed, and the spacing between the barrier bars on opposite sides tends to decrease from far to near.

[0042] The water absorption module 60 is arranged in the machine body. The water absorption module 60 includes a water absorption motor and an impeller 61. The water absorption motor is fixedly arranged in the machine body and has the ability to rotate forward and reverse. The impeller 61 is connected to the output end of the water absorption motor to be driven to rotate forward or reverse; Figure 4 and Figure 5 As shown, the impeller 61 is located in the middle of the water inlet channel 80, dividing the water inlet channel 80 into a front channel 81 and a rear channel 82. The suction side of the impeller 61 is connected to the inner cavity of the fuselage to create a negative pressure environment in the fuselage to absorb water, and the discharge side of the impeller 61 is connected to the inside of the water inlet channel 80; Figure 5 As shown, the water inlet channels 80 on both sides of the impeller 61 are streamlined, ensuring that the water discharged from the impeller 61 can be discharged smoothly.

[0043] The filter screen 70 is arranged in the body, between the water inlet 23 and the inlet of the water inlet module 60. The filter screen 70 includes a frame and a filter screen (not shown in the figure). The filter screen is arranged on the frame; Figure 8 As shown, the lower end of the grid is provided with an embedded groove; Figure 9 As shown, a bracket is fixedly provided inside the base 20; the embedded groove matches the bracket to fix the filter 70. Such a setting can ensure that the filter can cover a large area inside the base 20 and is placed more conveniently and firmly.

[0044] The machine body is also equipped with a controller (not shown), a magnetic component 91, and a Hall effect sensor 92. The magnetic component 92 is mounted on the running wheel 40; the Hall effect sensor 91 is installed inside the base 20 near the running wheel 40. The Hall effect sensor 91 corresponds to the magnetic component 92 to sense the machine body's movement. The controller is connected to the Hall effect sensor 91, which is in turn connected to the water suction motor to control the forward and reverse rotation of the water suction motor, thereby controlling whether the water discharged from the impeller 61 is directed to the front channel 81 or the rear channel 82.

[0045] Working Principle: The robot is placed at the bottom of the pool. The suction motor is activated to create a negative pressure inside the robot, drawing sewage from the pool bottom into the robot. Because the filter 70 is located between the suction port 23 and the impeller 61, the sewage is filtered and trapped within the robot before being drawn in by the impeller 61. The clean water, free of waste, is then drawn in by the impeller 61 and discharged through it into either the front channel 81 or the rear channel 82. The specific channel into which it is discharged is determined by the forward or reverse rotation of the suction motor. Taking the initial setting of discharging into the rear channel 82 as an example, the clean water is discharged from the rear channel 82 to the outside of the fuselage, and the fuselage obtains the propulsion force to move forward. The fuselage moves forward to clean the pool bottom in front. After the fuselage cleans the edge of the pool bottom, it is blocked by the pool wall and the running wheel 40 stops rotating. The Hall sensor 91 located in the fuselage cannot obtain the movement of the magnetic part 92 located on the running wheel 40. Therefore, the controller controls the water suction motor to switch the output direction, so that the impeller 61 rotates in the opposite direction and discharges the clean water into the front channel 81. Since the drainage direction is opposite, the fuselage will retreat. When retreating, the guide wheel 50 can move eccentrically to ensure that the fuselage will not move along the original forward path when retreating, and can clean a new part of the pool bottom. Repeating this operation can automatically clean the entire pool bottom.
