[0042] As shown in FIGs. 1 to 3, an electric robot includes a housing 100, an impeller 200, a suction motor 300, and a filter structure 400. The housing 100 is provided with a water inlet 110 and a water outlet 120. The impeller 200 is disposed in the housing 100. The impeller 200 is disposed between the water inlet 110 and the water outlet 120. The suction motor 300 is disposed in the housing 100. The suction motor 300 includes a motor main body 310 and a motor shaft 320 provided on the motor main body 310. The impeller 200 is sleeved-disposed in the motor shaft 320. The suction motor 300 drives the impeller 200 to rotate about the axis of the motor shaft 320 through the motor shaft 320 to generate suction. The rotational speed of the motor shaft 320 is adjustable.The filter structure 400 is disposed inside the housing 100, and the filter structure 400 is disposed between the turbine 200 and the water outlet 120.

[0043] In actual use, the electric robot proposed herein is deployed in an artificial pond (e.g., a swimming pool) to be cleaned, and the suction motor 300 is started to drive the impeller 200 to rotate around the axis of the motor shaft 320 through the motor shaft 320 to generate suction, so that the wastewater close to the water inlet 110 is sucked into the housing 100 through the water inlet 110. The wastewater entering the housing 100 is filtered by the filter structure 400 and then discharged through the water outlet 120. Since the filter structure 400 is arranged at the rear, the filter structure 400 or the solid dirt intercepted by the filter structure 400 will not block the suction force generated by the rotation of the impeller 200, so as to improve the capacity suction, and improves significantly improve the suction efficiency and applicability. In addition, the rotational speed of the motor shaft 320 of the suction motor 300 is adjustable, so that the rotational speed of the motor shaft 320 can be increased to generate greater suction when encountering stubborn stains, further improving the suction capacity. The suction effect is particularly remarkable for leaves or strip waste and gravel.

[0044] The electric robot proposed in this invention is used in artificial basins such as swimming pools to clean the water in the artificial basins.

[0045] Referring to FIGS. 1-2 and 5, the water inlet 110 is provided at the bottom of the housing 100, and the water outlet 120 is provided at the top of the housing 100.

[0046] Referring to FIGS. 2 and 4, the electric robot further comprises a receiving housing 500. The receiving housing 500 is provided in the housing 100. The receiving housing 500 includes a motor cavity 510 and a turbine cavity 520 spaced apart from each other. The main body of the motor 310 of the suction motor 300 is disposed in the motor cavity 510. The impeller 200 is disposed in the impeller cavity 520. The shaft of the motor 320 partially extends into the impeller cavity 520 to be connected to the impeller 200. One end of the impeller cavity 520 is connected to the water inlet 110, and the other end of the impeller cavity 520 is connected to the filter structure 400. In this embodiment, the impeller cavity 520 is a water inlet channel.

[0047] Referring to FIGS. 2-3, the motor shaft 320 is fitted with a sealing member 600 around the outer periphery of the motor shaft 320. The sealing member 600 is located between the motor cavity 510 and the turbine cavity 520. The sealing member is used to seal between the motor cavity 510 and the turbine cavity 520, so as to prevent wastewater that enters the turbine cavity 520 from entering the motor cavity 510. In this embodiment, the sealing member 600 is a sealing ring. The sealing ring is an annular structure. The sealing ring is sleeved on the motor shaft 320. The inner peripheral wall of the sealing ring is in close contact with the outer periphery of the motor shaft 320.The outer peripheral wall of the sealing ring is in close contact with the partition plate between the turbine cavity 520 and the motor cavity 510, so as to realize the sealing between the motor cavity 510 and the turbine cavity 520.

[0048] Referring to FIGs. 2 and 4, the filter structure 400 comprises a frame 410 and a filter screen disposed at an outer periphery of the frame 410. The frame 410 and the filter screen are correspondingly provided with a flow port 411. The turbine cavity 520 is connected to the interior of the frame 410 through the flow port 411.

[0049] More specifically, the wastewater near the water inlet 110 enters the turbine cavity 520 via the water inlet 110 under the suction force generated by the turbine 200. Then, the wastewater inside the turbine cavity 520 flows into the frame 410 of the filter structure 400, then flows out after being filtered by the filter screen at the outer periphery of the frame 410, and then flows outside the electric robot through the water outlet 120. In this way, the solid materials such as dirt and waste remain in the frame 410 of the filter structure 400, and the clean water obtained after separating the wastewater from the dirt and waste flows through the meshes of the filter screen.

[0050] Referring to [Fig. 2], in this embodiment, the turbine 200 is located between the water inlet 110 and the suction motor 300. With such an arrangement, the turbine 200 is closer to the water inlet 110, thereby generating a greater suction force when the turbine 200 rotates. In other embodiments, the suction motor 300 may be disposed between the water inlet 110 and the turbine 200.

[0051] Referring to [Fig.2], the turbine 200 is located between the water inlet 110 and the suction motor 300, which means that the turbine 200 is located below the suction motor 300, so that the turbine 200 is closer to the water inlet 110 at the bottom of the housing 100. At this time, the turbine cavity 520 for housing the turbine 200 is located below the motor cavity 510 for housing the suction motor 300.

[0052] Referring to FIGS. 1 and 4, the electric robot further includes a first travel motor 710 and a first track wheel 720, and a second travel motor 810 and a second track wheel 820. The first travel motor 710 is in transmission connection with the first track wheel 720. The second travel motor 810 is in transmission connection with the second track wheel 820. The first travel motor 710 and the second travel motor 810 are disposed in the housing 100. The first track wheel 720 and the second track wheel 820 are disposed on opposite sides of the housing 100, respectively. The first travel motor 710 is used to drive the first track wheel 720 to rotate. The second travel motor 810 is used to drive the second track wheel 820 to rotate.The first travel motor 710 is configured to perform forward and reverse rotation. The second travel motor 810 is configured to perform forward and reverse rotation. More specifically, the first travel motor 710 and the second travel motor 810 rotate forward at the same time, so as to drive the electric robot forward through the first track wheel 720 and the second track wheel 820. The first travel motor 710 and the second travel motor 810 rotate in opposite directions. at the same time, so as to drive the electric robot backward through the first track wheel 720 and the second track wheel 820. When one of the first travel motor 710 and the second travel motor 810 rotates forward, and the other rotates in the opposite direction, the first track wheel 720 and the second track wheel 820 drive the electric robot to rotate. In this embodiment, relative to the rotation direction of the first travel motor 710 and the second travel motor 810, the direction of driving the electric robot forward by the corresponding track wheel is the forward direction, and vice versa in the backward direction.

[0053] Referring to FIGs. 1 and 4, the first travel motor 710 is in transmission connection with the first track wheel 720 via the transmission gear 900. The second travel motor 810 is in transmission connection with the second track wheel 820 via the transmission gear 900. The transmission gear 900 is a conventional transmission gear in the prior art, and the matching relationship of the transmission gear 900 with the motor and the track wheel is the same as in the prior art.

[0054] Referring to FIGS. 2 and 4, the electric robot further includes a waterproof housing 1000. The waterproof housing 1000 is disposed inside the housing 100. The first travel motor 710 and the second travel motor 810 are disposed inside the waterproof housing 1000, thereby preventing water from entering the first travel motor 710 and the second travel motor 810.

[0055] Referring to FIGS. 2 and 4, the electric robot further includes a first roller brush 730 and a second roller brush 830 disposed at the front end of the housing 100. The first roller brush 730 is in transmission connection with the first moving motor 710. The second roller brush 830 is in transmission connection with the second moving motor 810. The first roller brush 730 and the second roller brush 830 can rotate by friction relative to the surface to be cleaned to clean the surface to be cleaned. More specifically, the first roller brush 730 and the second roller brush 830 play an auxiliary cleaning role. When stains or dirt adhere to the surface to be cleaned, the friction between the first roller brush 730 and the surface to be cleaned and the friction between the second roller brush 830 and the surface to be cleaned can clean the stain or dirt from the surface to be cleaned.The suction force generated by the rotation of the turbine 200 sucks the cleaned stains and dirt through the water inlet 110 into the housing 100.

[0056] Referring to [Fig.4], the first travel motor 710 is connected to the first roller brush 730 via the transmission gear 900, and the second travel motor 810 is connected to the second roller brush 830 via the transmission gear 900.

[0057] Referring to [Fig. 5], a brush strip 1100 is provided at the bottom of the housing 100. The brush strip 1100 is arranged on the side of the water inlet 110 near the rear end of the electric robot, so that when the electric robot moves, the brush strip 1100 can collect dirt near the water inlet 110. In this embodiment, the number of brush strips 1100 is two. The two brush strips 1100 are arranged on both sides of the water inlet 110. The opening distance of the two brush strips 1100 gradually decreases from the one end of the electric robot to the rear end of the electric robot, so that the two brush strips 1100 gather dirt near the water inlet 110.

[0058] Referring to FIGS. 2 and 4, the electric robot further includes a printed circuit board (PCB) control board 1200. The PCB control board 1200 is in transmission connection with the suction motor 300, the first travel motor 710 and the second travel motor 810. The PCB control board 1200 is used to control the suction motor 300, the first travel motor 710 and the second travel motor 810 to start and stop. The PCB control board 1200 is also used to adjust the rotation speed of the motor shaft 320 of the suction motor 300. The PCB control board 1200 is also used to perform switching between forward and reverse rotation of the first travel motor 710 and the second travel motor 810.In this embodiment, the PCB control board 1200 is provided in the waterproof housing 1000, thereby preventing water from entering the PCB control board 1200.

[0059] Referring to FIGs. 1-2, the electric robot further includes a sensor 1300. The sensor 1300 is disposed in an outer side wall of the housing 100. The sensor 1300 is in transmission connection with the PCB control board 1200. The sensor 1300 is used to detect the angle change of the electric robot. The sensor 1300 is used to send a signal to the PCB control board 1200 when it detects that the angle of the electric robot with the ground is greater than 30 degrees, then the PCB control board 1200 increases the rotation speed of the motor shaft 320 of the suction motor 300. Concretely, when the sensor 1300 detects that the angle between the electric robot and the ground is greater than 30 degrees, it indicates that the electric robot starts to climb the wall, and the first end of the electric robot is inclined.At this time, the rotation speed of the motor shaft 320 of the suction motor 300 is increased, so that the turbine 200 rotates to generate a greater suction force, thereby enabling the electric robot. to reliably adsorb on the wall. In this invention, the filter structure 400 is placed backward, and the rotation speed of the motor shaft 320 of the suction motor 300 is increased to strengthen the suction force twice. Thus, the present invention can ensure that the electric robot can reliably climb the wall by virtue of the suction force generated by the rotation of the turbine 200, and there is no need to rely on the pressure of the water sprayed from the water outlet 120.

[0060] Furthermore, when climbing the wall, the first travel motor 710 and the second travel motor 810 maintain forward rotation. After a period of forward rotation, the first travel motor 710 and the second travel motor 810 simultaneously rotate in the opposite direction, and the suction motor 300 decelerates to allow the electric robot to move back from the wall.

[0061] When climbing a wall, the suction motor 300 is accelerated so that the electric robot reliably adsorbs on the wall. When not climbing the wall, the suction motor 300 decelerates to save energy.

[0062] The sensor 1300 can determine whether the electric robot touches an obstacle or the pool wall. The sensor 1300 is used to send a signal to the PCB control board 1200 when it detects that the electric robot encounters the obstacle or the pool wall, by which the PCB control board 1200 changes the rotation direction of the first travel motor 710 and the second travel motor 810.

[0063] In addition, the sensor 1300 is a gyroscope. More specifically, the gyroscope can detect the angular velocity of the electric robot in the three XYZ directions, so as to determine the change of movement of the electric robot in space. In addition, when the gyroscope detects that the acceleration of the electric robot in the three XYZ directions is unchanged, it indicates that the electric robot is not moving. At this time, it can be judged that the electric robot touches the obstacle or the wall of the pool, and then the electric robot can change the moving direction to continue cleaning other areas.

[0064] Furthermore, the running trajectory of the electric robot can be set in advance, and the electric robot can be controlled to clean the artificial pond to be cleaned along the preset running trajectory through the cooperation of the sensor 1300 and the PCB control board 1200. Specifically, the sensor 1300 determines whether the electric robot reaches a turn in the running trajectory, and then feeds back to the PCB control board 1200. Then, the PCB control board 1200 controls the suction motor 300, the first moving motor 710 and the second moving motor of movement 810 according to the feedback from the sensor 1300, to ensure that the electric robot does not deviate from the predefined running path.

[0065] More specifically, two preset times can be set. If the sensor 1300 does not detect that the product is tilted at the first specified preset time, the first travel motor 710 and the second travel motor 810 are switched to reverse rotation, so as to cause the electric robot to change the travel direction. Or during the operation process, the first travel motor 710 and the second travel motor 810 set one travel motor to forward rotation and the other travel motor to reverse rotation according to the second preset time, at which time the electric robot changes the travel direction.

[0066] The suction motor 300 starts first during operation of the electric robot. The first moving motor 710 and the second moving motor 810 start after a few seconds.

[0067] Referring to FIGs. 2 and 4, the electric robot further includes a deflector 1400. The deflector 1400 is provided in the housing 100. The deflector 1400 is disposed between the impeller 200 and the water inlet 110. The axis extension line of the motor shaft 320 passes through the deflector 1400. More specifically, the deflector 1400 is provided such that when the wastewater enters the housing 100 through the water inlet 110, the wastewater will impact the deflector 1400. Then, the wastewater spreads into the housing 100 from the periphery of the deflector 1400. Since the motor shaft extension line 320 passes through the deflector 1400, the deflector 1400 covers the end of the motor shaft 320 near the 1400 deflector.Thus, the waste in the waste water will not be entangled at the end of the motor shaft 320 near the deflector 1400, thereby preventing many leaves or strips of waste from becoming entangled in the motor shaft 320 and slowing down the rotational speed of the drive member, thereby preventing the waste in the waste water from affecting the suction efficiency.

[0068] The electric robot further includes a power supply structure that powers the electric robot.

[0069] Referring to FIGs. 2 and 4, the electric robot further includes a connecting member 1500. One end of the connecting member 1500 is connected to the baffle 1400, and the other end of the connecting member 1500 is connected to the inner wall of the housing 100.

[0070] In one embodiment, the connecting element 1500 is integrally molded with the deflector 1400. More specifically, the connecting element 1500 is attached to the interior wall of the housing 100 by screws or to the interior wall of the housing 100 by a spring clip.

[0071] Referring to [Fig. 2], the outer peripheral profile of the deflector 1400 is a curved surface gradually narrowing from the end near the turbine 200 to the end far from the turbine 200. More specifically, the periphery of the end of the deflector 1400 far from the turbine 200 (referring to the lower end of the deflector 1400) is relatively narrow. The periphery of the end of the deflector 1400 near the turbine 200 (referring to the upper end of the deflector 1400) is relatively wide. Thus, the effluent from the lower end of the deflector 1400 to the upper end of the deflector 1400 gradually spreads toward the periphery of the deflector 1400.Therefore, when the wastewater flows just toward the turbine 200, the wastewater is further away from the axis of the motor shaft 320, which further prevents waste in the wastewater from becoming entangled on the end of the motor shaft 320 near the deflector 1400.

[0072] The deflector 1400 may, but is not limited to, being a hemispherical structure, a conical structure, or a parabolic structure. In this embodiment, with reference to [Fig. 1], the deflector 1400 is a hemispherical structure.

[0073] Referring to [Fig.2], the deflector 1400 is a rotating body. The axis of the motor shaft 320 coincides with the axis of the deflector 1400. More specifically, when the wastewater flows from the lower end of the deflector 1400 to the upper end of the deflector 1400, the wastewater gradually spreads toward the periphery of the deflector 1400. Since the axis of the motor shaft 320 coincides with the axis of the deflector 1400, the surrounding wastewater is relatively far away from the axis of the motor shaft 320.

[0074] Referring to FIGS. 2-3, the turbine 200 includes a turbine column 210 and a blade 220. The turbine column 210 is sleeved onto the motor shaft 320. The blade 220 is spirally wound onto the turbine column 210. More specifically, the blade 220 is spirally wound, which facilitates the upward transport of waste in the wastewater.

[0075] The embodiments described above are merely those preferred in the description, which are not intended to limit the invention. It should be understood that any modifications and replacements may be made by those skilled in the art without departing from the scope of the invention.
