[0062] The present invention provides a mop module 10 .
[0063] In the embodiment of the present invention, please refer to Figure 1 and Figure 2 The mop module 10 includes a mop assembly 11, a rotation drive structure 12 and a lifting drive structure 13. The rotation structure is connected to the mop assembly 11 and drives the mop assembly 11 to rotate; the rotation structure is connected to the mop assembly 11 and drives the mop assembly 11 to lift.
[0064] When it is determined that there is hair on the ground, the lifting drive structure 13 is controlled to drive the mop assembly 11 to descend, so that the mop assembly 11 contacts the hair, and then the rotating drive structure 12 is controlled to rotate. The rotating mop assembly 11 applies downward pressure to the hair, so that the hair sticks to the mop assembly 11, and the hair is transferred from the ground to the mop assembly 11. Finally, the lifting drive structure 13 is controlled to drive the mop assembly 11 to rise, so as to prevent the hair from being entangled in other parts of the cleaning robot, thereby realizing automatic cleaning of the ground hair and ultimately improving the user experience.
[0065] In one embodiment, the mop module 10 also includes a first visual sensor 30, which is electrically connected to the rotation drive structure 12 and the lifting drive structure 13; the first visual sensor 30 is used to detect the hair condition on the ground; the rotation drive structure 12 and the lifting drive structure 13 are used to perform corresponding actions according to the first detection result of the first visual sensor 30.
[0066] The mop module 10 is provided with a first visual sensor 30, which is fixed on the main body 20 of the cleaning robot and arranged opposite to the ground. When the first visual sensor 30 detects that there is hair on the ground, it sends a first detection result to the main controller of the cleaning robot, and the main controller outputs a control instruction according to the first detection result; when the first detection result is that there is hair on the working surface, the main controller controls the lifting drive structure 13 to descend, so that the mop assembly 11 of the mop module 10 descends, and then controls the rotation drive structure 12 to rotate, so that the mop assembly 11 contacts and rotates with the working surface, so that the mop assembly 11 is adsorbed with the hair. When the first detection result is that there is no hair on the working surface, the main controller does not control the operation of the mop module 10; in this way, the first visual sensor 30 is matched with the main controller, and the action of the mop module 10 can be controlled more accurately.
[0067] In one embodiment, the mop module 10 also includes a humidity sensor, which is electrically connected to the rotating drive structure 12 and the lifting drive structure 13; the humidity sensor is used to detect the hair humidity on the ground; the rotating drive structure 12 and the lifting drive structure 13 are used to perform a response action based on the second detection result of the humidity sensor.
[0068] The humidity of the hair specifically refers to the amount of water attached to the surface of the hair. The mop module 10 is provided with a humidity sensor, which is fixed on the main body 20 of the cleaning robot and arranged opposite to the ground. When the first visual sensor 30 detects that there is hair on the ground, and then detects that the hair on the ground is wet through the humidity sensor, the main controller will control the mop module 10 to enter the wet hair cleaning program. When the humidity sensor detects that the hair on the ground is dry hair, the main controller will control the mop module 10 to enter the dry hair cleaning program. With this arrangement, the mop module 10 can perform a more delicate action of absorbing the hair according to the humidity of the hair, thereby improving the cleaning effect of the mop module 10 in cleaning the hair.
[0069] In one embodiment, the mop module 10 also includes a second visual sensor, which is electrically connected to the rotation drive structure 12 and the lifting drive structure 13; the second visual sensor is used to detect the situation of hair sticking to the mop assembly 11; the rotation drive structure 12 and the lifting drive structure 13 are used to perform corresponding actions according to the third detection result of the second visual sensor.
[0070] In this embodiment, the mop module 10 is provided with a second visual sensor, which is fixed on the main body 20 of the cleaning robot and arranged opposite to the mop assembly 11 of the mop module 10. When the second visual sensor detects that the mop assembly 11 of the mop module 10 absorbs too much hair, the main controller controls the mop module 10 to stop running, and then controls the roller to move, so that the entire cleaning robot moves to the base station, and the hair of the mop module 10 can be cleaned through the base station. When the second visual sensor detects that the mop assembly 11 of the mop module 10 does not have a lot of hair, the main controller continues to control the mop module 10 to clean the hair on the working surface. In this way, the second visual sensor is matched with the main controller, and the situation of the mop module 10 absorbing hair can be detected in real time, so that the hair of the mop module 10 can be cleaned in time.
[0071] In one embodiment, see Figures 2 to 4 The mop assembly 11 includes a lifting member 111, a rotating member 112 and a mop 113. The lifting member 111 is connected to the lifting drive structure 13, and the lifting member 111 is provided with a through hole; the rotating member 112 is rotatably connected in the through hole and protrudes from the through hole; and the rotating member 112 is connected to the rotary drive structure 12; the mop 113 is connected to one end of the rotating member 112 protruding from the through hole.
[0072] When it is determined that there is hair on the ground, the lifting drive structure 13 is controlled to drive the lifting member 111 to descend, and the lifting member 111 drives the rotating member 112 and the mop 113 to descend synchronously until the mop 113 contacts the hair on the ground. Then the rotating drive structure 12 is controlled to drive the rotating member 112 to rotate relative to the lifting member 111, and the rotating member 112 drives the mop 113 to rotate synchronously. The rotating mop 113 will apply downward pressure to the hair on the ground, so that the hair sticks to the mop 113, and the hair on the ground can be transferred to the mop 113, thereby completing the cleaning of the hair on the ground. After the hair sticks to the mop 113, the lifting drive structure 13 is then controlled to drive the lifting member 111 to rise, and the lifting member 111 drives the rotating member 112 and the mop 113 to rise synchronously. In this way, the hair stuck to the mop 113 will not come into contact with other parts of the cleaning robot, thus preventing the hair from being entangled in other parts of the cleaning robot. Manual cleaning is not required by the user, and the rising lifting member 111, rotating member 112 and mop 113 will not block the subsequent operation of the cleaning robot.
[0073] The lifting member 111 and the rotating member 112 in the mop assembly 11 of this embodiment move independently without interfering with each other, and the rotating member 112 is rotatably connected to the through hole in the lifting member 111, so that the structure of the mop assembly 11 is more compact.
[0074] In one embodiment, see Figures 2 to 4 The rotating member 112 includes a rotating drum 1121 and a mounting plate 1122, wherein the rotating drum 1121 is connected to the rotating drive structure 12; the rotating drum 1121 is rotatably connected in the through hole, and one end of the rotating drum 1121 away from the rotating drive structure 12 protrudes from the through hole; the mounting plate 1122 is connected to one end of the rotating drum 1121 protruding from the through hole, and the mop 113 is installed on the side of the mounting plate 1122 facing away from the rotating drum 1121.
[0075] Specifically, a ball bearing or a sliding component is arranged between the outer wall of the rotating drum 1121 and the hole wall of the through hole of the lifting member 111 to realize the rotational connection; the rotating member 112 of this embodiment is divided into a rotating drum 1121 and a mounting plate 1122, the rotating drum 1121 is used for the matching connection between the lifting member 111 and the rotary drive structure 12, and the mounting plate 1122 is used for connecting with the mop 113. With such an arrangement, when the mop 113 needs to be replaced, it is only necessary to directly operate on the side of the mounting plate 1122 facing away from the rotating drum 1121, and there is no need to disassemble the entire rotating member 112 for replacement, thereby improving the convenience of use of the hair cleaning mechanism.
[0076] In one embodiment, see Figures 2 to 4The outer wall of the lifting member 111 is provided with a limiting groove; the mop module 10 also includes a limiting member 14, the limiting member 14 includes a limiting rod 141 and a limiting ring 142, the limiting rod 141 is fixed to the bottom of the cleaning robot and movably connected to the limiting groove; the limiting ring 142 is connected to one end of the limiting rod 141 away from the limiting groove, and the limiting ring 142 is used to limit the position of the lifting member 111 in the vertical direction.
[0077] Specifically, the limiting groove is arranged on the outer wall of the lifting member 111 and extends a certain length along the outer wall of the lifting member 111; when the lifting drive structure 13 drives the lifting member 111 to rise and fall, the lifting member 111 can slide in the limiting groove through the limiting rod 141, so that the lifting member 111 uses the groove wall of the limiting groove to limit the lifting position along the vertical direction, and is not easy to deviate to other positions; when the lifting member 111 is driven by the lifting drive structure 13 to rise to a preset height, the limiting ring 142 abuts against the lifting member 111, thereby preventing the lifting member 111 from rising excessively and avoiding the lifting member 111 from colliding with the transmission gear 122, thereby ensuring that the lifting member 111 can operate normally.
[0078] In one embodiment, see Figures 2 to 4 The rotating drive structure 12 includes a first driving motor 121, a transmission gear 122 and a rotating shaft 123. The first driving motor 121 is arranged at the bottom of the cleaning robot, and the output shaft of the first driving motor 121 is provided with a turbine 121a; the transmission gear 122 is rotatably connected to the bottom of the cleaning robot and meshed with the turbine 121a; the rotating shaft 123 is penetrated by the transmission gear 122 and connected to the mop assembly 11.
[0079] The rotary drive structure 12 of the present embodiment realizes the transmission between the first drive motor 121 and the rotating member 112 through the cooperation of the transmission gear 122 and the rotating shaft 123. Since the transmission gear 122 has a constant transmission ratio, the transmission efficiency of the first drive motor 121 to the rotating member 112 is further improved, and the transmission loss is greatly reduced. At the same time, the transmission gear 122 has a compact structure and a small size, and can be easily integrated at the bottom of the cleaning robot to achieve maximum utilization of the bottom space of the cleaning robot.
[0080] For further information, see Figures 2 to 4The transmission gear 122 includes a first gear 122a and a second gear 122b, the first gear 122a is rotatably connected to the bottom of the cleaning robot and meshed with the turbine 121a; the second gear 122b is rotatably connected to the bottom of the cleaning robot and meshed with the first gear 122a; the rotating shaft 123 passes through the second gear 122b and is connected to the rotating member 112; and the diameter of the second gear 122b is greater than the diameter of the first gear 122a.
[0081] In this embodiment, when the first drive motor 121 drives the turbine 121a to rotate, the turbine 121a drives the first gear 122a to rotate, and then the first gear 122a drives the second gear 122b to rotate, and finally the second gear 122b drives the rotating member 112 to rotate through the rotating shaft 123; since the diameter of the second gear 122b is greater than the diameter of the first gear 122a, when the first gear 122a drives the second gear 122b to rotate, according to the principle of gear transmission ratio, the rotation speed of the second gear 122b will slow down, and the force output by the second gear 122b will also increase, thereby increasing the force of the second gear 122b to drive the rotating member 112 to rotate, thereby increasing the transmission force of the first drive motor 121, and finally making the mop 113 easier to rotate.
[0082] In one embodiment, see Figures 2 to 4 The rotating member 112 is provided with a first slot; the rotating shaft 123 includes a connecting shaft 123a and a sleeve 123b, one end of the connecting shaft 123a is inserted into the transmission gear 122; one end of the sleeve 123b is movably inserted into the first slot, so that the rotating member 112 can move up and down relative to the sleeve 123b; the other end of the sleeve 123b is provided with a second slot, and one end of the connecting shaft 123a away from the transmission gear 122 is movably inserted into the second slot, so that the sleeve 123b can move up and down relative to the connecting shaft 123a.
[0083] In this embodiment, the rotating shaft 123 is divided into a connecting shaft 123a and a sleeve 123b. The connecting shaft 123a is actually inserted into the second gear 122b of the transmission gear 122. The connecting shaft 123a and the second gear 122b are fixedly connected. The second gear 122b drives the connecting shaft 123a to rotate. The connecting shaft 123a is movably plugged into the second slot provided with the sleeve 123b, so that the sleeve 123b can be lifted relative to the connecting shaft 123a fixedly connected to the second gear 122b, so that the rotating member 112 connected to the sleeve 123b can be lifted. The first slot is rotatably provided, and the other end of the sleeve 123b away from the transmission gear 122 is movably plugged into the first slot, so that the rotating member 112 can be lifted relative to the sleeve 123b, thereby lifting the mop 113 connected to the rotating member 112. In this way, the mop 113 can be raised and lowered in two stages, thereby making the lifting and lowering adjustment accuracy of the mop 113 higher, making it easier for the mop 113 to contact the hair on the ground, and making it easier for the mop 113 to collect the hair.
[0084] For further information, see Figure 2 and Figure 5 The outer wall of the connecting shaft 123a is provided with a plane 1231a; the side wall of the second slot is provided with a spline 1231b, and the spline 1231b is in contact with the plane 1231a so that the connecting shaft 123a drives the sleeve 123b to rotate; the radial cross-sectional shape of the sleeve 123b and the transverse cross-sectional shape of the first slot are both polygonal.
[0085] Specifically, a plane 1231a is set on the outer wall of the connecting shaft 123a, so that when the connecting shaft 123a drives the sleeve 123b to rotate, the sleeve 123b uses the mutual limitation of the spline 1231b and the plane 1231a to prevent the sleeve 123b from slipping relative to the connecting shaft 123a, thereby allowing the connecting shaft 123a to effectively drive the sleeve 123b to rotate.
[0086] The radial cross-sectional shape of the sleeve 123b and the transverse cross-sectional shape of the first slot are both hexagonal. With such arrangement, when the sleeve 123b drives the rotating member 112 to rotate, the outer wall of the sleeve 123b and the side wall of the first slot of the rotating member 112 can limit each other, thereby not only avoiding the sleeve 123b and the rotating member 112 from slipping on each other, but also ensuring that the rotating member 112 slides on the outer wall of the sleeve 123b through the side wall of the first slot, thereby realizing the lifting and lowering of the rotating member 112 relative to the sleeve 123b.
[0087] For further information, see Figure 2 and Figure 5A limiting surface 1232a is provided on the outer wall of the connecting shaft 123a, and the limiting surface 1232a is arranged near the end of the connecting shaft 123a where it is matched with the transmission gear 122; the limiting surface 1232a is used to limit the rising displacement of the sleeve 123b; a limiting protrusion 1232b is provided on the outer wall of one end of the sleeve 123b close to the transmission gear 122, and the limiting protrusion 1232b is located at the end of the sleeve 123b close to the transmission gear 122, and is used to limit the lifting and lowering range of the rotating member 112.
[0088] Specifically, the limiting surface 1232a is arranged along the radial extension of the connecting shaft 123a, that is, the limiting surface 1232a is arranged along the horizontal direction; when the lifting drive structure 13 drives the sleeve 123b to rise, and until the top end surface of the sleeve 123b abuts against the limiting surface 1232a of the connecting shaft 123a, the limiting surface 1232a blocks the sleeve 123b from continuing to move upward, thereby preventing the sleeve 123b from excessively rising and colliding with the second gear 122b of the transmission gear 122; the limiting protrusion 1232b is arranged around the outer wall of the sleeve 123b, and when the lifting drive structure 13 drives the rotating member 112 to rise, and until the top end surface of the rotating member 112 abuts against the limiting protrusion 1232b, the limiting protrusion 1232b blocks the rotating member 112 from continuing to move upward, thereby preventing the rotating member 112 from excessively rising and pushing the sleeve 123b to collide with the second gear 122b.
[0089] In one embodiment, see Figure 2 and Figure 3 The lifting drive structure 13 includes a second drive motor 131, a connecting rod 132, a slider 133 and a lifting rod 134. The second drive motor 131 is arranged at the bottom of the cleaning robot and is spaced apart from the rotating drive structure 12; one end of the connecting rod 132 is connected to the output shaft of the second drive motor 131; the slider 133 is connected to the other end of the connecting rod 132; the lifting rod 134 is connected to the outer wall of the lifting member 111, and the lifting rod 134 is provided with a slide groove, which extends along the length direction of the lifting rod 134; the slider 133 is slidably connected in the slide groove.
[0090] In this embodiment, when it is necessary to drive the lifting member 111 to move up and down, it is only necessary to control the operation of the lifting drive member, and the lifting drive member drives the connecting rod 132 to rotate, so that the slider 133 also rotates with the connecting rod 132, and the slider 133 will slide in the slide groove of the lifting rod 134 during the rotation process, and drive the lifting rod 134 to move up and down, and the lifting rod 134 drives the lifting member 111 and the rotating member 112 to move up and down synchronously. The slider 133 and the lifting rod 134 in the lifting transmission member of this embodiment cooperate to slide in the horizontal direction, while realizing the lifting of the lifting member 111, it can also further reduce the installation space required for the lifting transmission member in the vertical direction, thereby preventing the lifting transmission member from colliding with the ground and affecting the transmission of the lifting transmission member.
[0091] In another embodiment, see Figure 2 and Figure 3 The rotary drive structure 12 includes a first drive motor 121, two transmission gears 122 and two rotating shafts 123; the mop assembly 11 includes two lifting members 111, two rotating members 112 and two mops 113; the first drive motor 121 is in transmission connection with the two transmission gears 122, and each rotating shaft 123 is connected to a transmission gear 122; each rotating member 112 is connected to a rotating shaft 123, and each mop 113 is connected to a rotating member 112; the two ends of the lifting rod 134 are respectively connected to the outer walls of the two lifting members 111.
[0092] In this embodiment, the two transmission gears 122 and the two rotating shafts 123 are both arranged at the bottom of the device body and are arranged side by side. Through the above arrangement, a rotating driving member synchronously drives the two lifting members 111, the two rotating members 112 and the two mops 113 of the mop assembly 11 to rotate through the two transmission gears 122 and the two rotating shafts, so that the two mops 113 of the mop assembly 11 can rotate and rise and fall at the same time, which can improve the cleaning efficiency of the mop module 10 and simplify the structure of the mop module 10.
[0093] The present invention also provides a cleaning robot, see Figure 1 and Figure 2 The cleaning robot includes a main body 20, a visual sensor 30 and the mop module 10 as described above. The visual sensor 30 is installed on the main body 20 and is used to detect whether there is hair on the ground; the mop module 10 is arranged on the main body 20 and is spaced apart from the visual sensor 30.
[0094] The main body 20 includes a shell, a main controller, a roller and a roller brush dust suction assembly. The main controller and the first visual sensor 30 are installed in the shell. The roller is rotatably connected to the bottom of the shell. The roller brush dust suction assembly is installed at the bottom of the shell and is spaced apart from the roller. The roller brush dust suction assembly is used to absorb other garbage except hair from the ground. A accommodating space is provided at the bottom of the shell. The mop module is installed in the accommodating space. The main controller is electrically connected to the first drive motor 121 of the rotating drive structure 12, the second drive motor 131 of the lifting drive structure 13 and the first visual sensor 30.
[0095] When the first visual sensor 30 detects hair on the ground, the main controller determines that there is hair on the ground based on the detection result of the first visual sensor 30, and the main controller first controls the roller to turn around so that the mop module 10 originally located at the rear is adjusted to the front, and then controls the roller to drive the cleaning robot to move above the hair, and controls the mop module 10 to rise and fall, and the lowest descending position of the mop module 10 is flush with the bottom of the roller, and controls the mop module 10 to clean the hair. After the mop module 10 completes the hair cleaning, the mop module 10 is finally controlled to rise into the accommodating space to avoid position interference between the mop module 10 and the roller brush suction component, which affects the roller brush suction component's cleaning of garbage other than hair on the ground.
