[0028] See also Figure 1A cleaning device of a cleaning robot includes a roller brush mechanism 1 and a roller mechanism 2. The roller brush mechanism 1 includes a first shell 10, a first lifting assembly 11, a roller brush member 12, a garbage box 13 with an opening, and a first driving assembly 14. The first shell 10 is provided with a first cavity 100 with an opening. The first lifting assembly 11 is provided on the first shell 10. The roller brush member 12 is provided in the first cavity 100. One end of the roller brush member 12 extends out of the opening of the first cavity 100. The garbage box 13 is provided in the first cavity 100. The opening of the garbage box 13 is provided corresponding to the roller brush member 12. The first driving assembly 14 is provided on the first shell 10. The first driving assembly 14 extends Extending to the first cavity 100 and connected to the roller brush member 12; the roller mechanism 2 includes a second shell 20, a roller member 21, a water spray assembly 22 and a second drive assembly 23. The second shell 20 is provided with a second cavity 200 with an opening. The roller member 21 is arranged in the second cavity 200, and one end of the roller member 21 extends out of the opening of the second cavity 200. The water spray assembly 22 is arranged on the second shell 20, and the water spray port of the water spray assembly 22 extends into the second cavity 200. The water spray port of the water spray assembly 22 is arranged corresponding to the roller member 21. The second drive assembly 23 is arranged on the second shell 20, and the second drive assembly 23 extends to the second cavity 200 and is connected to the roller member 21.

[0029] In the present application, the roller brush mechanism 1 has a working state and a non-working state. When the roller brush mechanism 1 is in the working state, the roller brush member 12 is in contact with the ground. When the roller brush mechanism 1 is in the non-working state, the roller brush member 12 is not in contact with the ground. The working state and the non-working state of the roller brush mechanism 1 are achieved by lifting the first shell 10 through the first lifting component 11, thereby driving the roller brush member 12 to lift and lower to contact the ground or not contact the ground. For the roller mechanism 2, the roller mechanism 2 also has a working state and a non-working state. When the roller mechanism 2 is in the working state, the roller member 21 is in contact with the ground. When the roller mechanism 2 is in the non-working state, the roller member 21 may be in contact with the ground or not contact the ground.

[0030] The roller brush mechanism 1 and the roller mechanism 2 enable the cleaning device of the cleaning robot to have the functions of sweeping, washing, mopping and dust-pushing. First, for the sweeping function, the specific process is as follows: the roller brush mechanism 1 is driven into the working state by the first lifting component 11. At this time, the roller brush member 12 contacts the ground and generates a small abutment and compression deformation. The roller brush member 12 is driven to rotate by the first driving component 14 to clean the ground. When the roller brush member 12 contacts the garbage on the ground, it pushes the garbage to the opening of the first cavity 100, causing the garbage to be squeezed against the inner wall of the opening of the first cavity 100. The steering force of the roller brush member 12 drives the garbage to move into the garbage box 13. Secondly, for the floor-washing function, the specific process is as follows: when the roller brush mechanism 1 is in operation, the roller brush member 12 is driven downward by the first lifting assembly 11. At this time, the roller brush member 12 contacts the ground and generates a large abutment compression deformation. Then, the water spray assembly 22 sprays water onto the ground. Finally, the first drive assembly 14 drives the roller brush member 12 to rotate to clean the ground. It should be noted that when the roller brush member 12 rotates to clean the ground, the roller member 21 can also rotate to mop the ground. Thirdly, for the floor-mopping function, the specific process is as follows: the water spray assembly 22 sprays water onto the ground or the roller member 21. Then, the second drive assembly 23 drives the roller member 21 to rotate to mop the ground. Fourth, for the dust-pushing function, the water spray assembly 22 sprays water onto the roller member 21 or does not spray water, and then the second drive assembly 23 drives the roller member 21 to rotate to dust-push the floor. Therefore, dust-pushing is a dry mopping mode or similar to dry mopping, and the amount of water sprayed by the water spray assembly 22 in dust-pushing mode is much smaller than that in mopping mode. It should be noted that the first drive assembly 14 drives the roller brush member 12 to rotate at different speeds in sweeping and washing modes, and the second drive assembly 23 drives the roller member 21 to rotate at different speeds in mopping and dust-pushing modes.

[0031] In the present application, the structure of the roller brush part 12 is a cylindrical support rod and a bristle structure, that is, a plurality of bristles are evenly distributed on the surface of the cylindrical support rod. The material of the bristles can be golden grass, bamboo tips, silicone or plastic, among which plastic materials with good deformation and high wear resistance are preferred. The structure of the roller part 21 is a cylindrical support rod and a mop structure, that is, the mop wraps the surface of the cylindrical support rod. The material of the mop can be nylon, polyester fiber or cotton cloth, among which cotton cloth with good water absorption is preferred.

[0032] In the present application, the water spray assembly 22 includes a water tank (not shown), a water pump (not shown), a control valve (not shown) and a water outlet. One end of the water pump is connected to the water tank, and the other end of the water pump is connected to the control valve. The water outlet is set at the control valve. When the water spray assembly 22 needs to spray different amounts of clean water, different water outputs are controlled by controlling the valve of the control valve. It should be noted that since the roller member 21 is a cylindrical support rod and mop structure with a fixed length, a water trough with multiple openings is provided on the top of the second cavity 200. The water trough is connected to the water outlet of the water spray assembly 22. The multiple openings of the water trough are arranged at intervals, and the multiple openings are all arranged corresponding to the surface of the roller member 21. When the clean water from the multiple openings is sprayed onto the surface of the roller member 21, the surface of the roller member 21 is quickly and evenly moistened.

[0033] For the above roller mechanism 2, see Figure 5-Figure 7 The roller mechanism 2 also includes a second lifting assembly 24, an extrusion assembly 25 and a sewage box 26 with an opening. The second lifting assembly 24 is arranged on the second shell 20, the extrusion assembly 25 is arranged in the second cavity 200, one end of the extrusion assembly 25 abuts against the surface of the compression roller member 21, and the sewage box 26 is arranged in the second cavity 200. The opening of the sewage box 26 is arranged below the surface of the extrusion assembly 25 abutting against the compression roller member 21.

[0034] In the present application, when the roller mechanism 2 is in a non-working state, in order to allow the roller member 21 to dry quickly and prevent the roller member 21 from being wet for a long time and causing bacteria to grow on the roller member 21, the second lifting assembly 24 drives the second shell 20 to rise and fall, thereby driving the roller member 21 to rise and fall, so that when the roller mechanism 2 is in a non-working state, the roller member 21 does not contact the ground. At the same time, since the roller member 21 does not contact the ground, the wet roller member 21 can be prevented from causing secondary pollution to the ground when the roller brush mechanism 1 is sweeping the floor.

[0035] In addition, during mopping and dust removal, the roller member 21 is deformed to different degrees by pressing against the ground. The second lifting assembly 24 can be used to control the roller member 21 to rise and fall, thereby controlling the deformation amount of the roller member 21 by pressing against the ground.

[0036] In the present application, the setting of the extrusion component 25 can enable the roller mechanism 2 to have the function of self-cleaning of the roller part 21. When the roller is rotating, it cleans while working, avoiding the dirty roller part 21 from causing secondary pollution to the ground. In addition, the sewage box 26 is set below the surface of the extrusion component 25 that presses the roller part 21, so that the sewage generated by the extrusion can fall into the sewage box 26, avoiding the sewage leaking to the ground and causing secondary pollution.

[0037] In the present application, by using the first lifting component 11 and the second lifting component 24 in coordination, the cleaning devices of the cleaning robot can perform different cleaning tasks without interfering with each other. Users can flexibly switch between different functions according to actual needs, thereby effectively improving the cleaning efficiency of the cleaning device of the cleaning robot.

[0038] For bin 13 above, see Figure 2-Figure 4 A first mounting opening 101 is provided on the side of the first shell 10, and the first mounting opening 101 is connected to the first cavity 100. The garbage box 13 is arranged along the first mounting opening 101 and extends into the bottom of the first cavity 100. The garbage box 13 covers the first mounting opening 101, and the opening of the garbage box 13 is arranged corresponding to the roller brush part 12.

[0039] In the present application, the trash bin 13 is installed in a detachable manner, similar to a drawer-type installation. The specific assembly and disassembly principle is as follows: a first adhesive member is provided at one end of the trash bin 13, and a second adhesive member is provided on the inner wall of the first cavity 100 corresponding to the first adhesive member. When the trash bin 13 is extended into the first cavity 100 along the first installation opening 101 under the action of an external force, and the first adhesive member and the second adhesive member adhere to each other, the installation of the trash bin 13 is completed. When the trash bin 13 is pulled out of the first cavity 100 along the first installation opening 101 under the action of an external force, and the first adhesive member is separated from the second adhesive member, the removal of the trash bin 13 is completed. The structure of the first adhesive member and the second adhesive member can be: a snap-on and slot structure, a Velcro structure, or a magnet structure. In the present application, a magnet structure is preferably used, that is, the first adhesive member and the second adhesive member are magnetically attracted to each other. The detachable installation method of the trash bin 13 makes it convenient for the user to clean the trash in the trash bin 13.

[0040] For the above roller brush mechanism 1, please refer to Figure 2 The roller brush mechanism 1 further includes a dust suction component 15 , which is disposed at one end of the first shell 10 away from the opening of the first cavity 100 .

[0041] In the present application, the roller brush 12 cannot complete the cleaning of small garbage, such as dust or debris. Therefore, by setting the dust suction component 15, the cleaning of such small garbage can be completed, enriching the function of the cleaning device of the cleaning robot and further improving the cleaning efficiency. It should be noted that since the dust suction component 15 is set at the end of the first shell 10 away from the opening of the first cavity 100, when the first lifting component 11 drives the roller brush 12 to rise and fall, the dust suction component 15 also follows the roller brush 12 to rise and fall.

[0042] For the above-mentioned dust collection component 15, please refer to Figure 2The dust collection assembly 15 includes a dust collection box 150, a first elastic member 151, a roller 152 and a dust collection main unit (not shown in the figure). The dust collection box 150 is provided with a dust collection cavity 150a with an opening. The dust collection box 150 is slidably arranged at one end of the first shell 10 away from the opening of the first cavity 100. One end of the first elastic member 151 is fixedly connected to one end of the first shell 10, and the other end of the first elastic member 151 is connected to the dust collection box 150. The roller 152 is arranged at the bottom of the dust collection box 150, and the dust collection main unit is arranged in the dust collection box 150, and one end of the dust collection main unit is connected to the dust collection cavity 150a.

[0043] In the present application, when the roller brush mechanism 1 is in operation, the ground contacts the roller 152 and exerts a force on the roller 152, causing the first elastic member 151 to elastically deform. Based on the elastic force of the first elastic member 151, the dust collection assembly 15 can adapt to different ground surfaces, that is, the dust collection box 150 always maintains an effective dust collection distance from the ground, thereby improving the dust collection effect of the dust collection assembly 15. The first elastic member 151 can act as a buffer when adapting to different ground surfaces. Furthermore, the vacuum main unit is implemented using existing technology, i.e., a small vacuum device that implements the vacuuming principle. Therefore, the vacuum main unit is not described in detail in this application.

[0044] For the first lifting assembly 11, please refer to Figure 2-Figure 8 The first lifting assembly 11 includes a bracket 110, a first drive motor 111, a lifting member 112 and a pressure spring 113. The bracket 110 is provided with a limiting slot 110a. One end of the bracket 110 is connected to the top of the first shell 10. The first drive motor 111 is arranged on the bracket 110. The lifting member 112 is slidably arranged in the limiting slot 110a. The first end of the lifting member 112 is driven and connected to the first drive motor 111. The second end of the lifting member 112 extends out of the limiting slot 110a. One end of the pressure spring 113 is connected to the second end of the lifting member 112. The other end of the pressure spring 113 is connected to the top of the first shell 10. The limiting slot 110a is used to limit the rotation of the lifting member 112 relative to the bracket 110.

[0045] In this application, the lifting process of the first lifting component 11 is as follows: the first driving motor 111 drives the lifting member 112 to lift and lower along the height direction of the limiting groove 110a, and then drives the pressure spring 113 to lift and lower, thereby driving the first shell 10 to lift and lower. It should be noted that in the process of the lifting member 112 lifting and lowering, due to the elastic action of the pressure spring 113, the pressure spring 113 can play a buffering role in the process of the roller brush member 12 contacting the ground and generating different deformations. Among them, the structure of the first lifting component 11 can be a chain sprocket transmission structure, a gear rack transmission structure or a screw transmission structure, among which the first lifting component 11 is preferably a screw transmission structure, that is, the lifting member 112 is a plurality of gears, a screw and a lifting block with a threaded hole, and the plurality of gears are meshed with each other, one gear is connected to the first drive motor 111, and the other gear is connected to the screw, and the screw is rotated and set in the limiting groove 110a, the lifting block passes through the screw and is threadedly connected to the screw, and the lifting block is set in the limiting groove 110a, and the lifting block can move along the length direction of the screw, and one end of the lifting block is connected to the pressure spring 113, among which the plurality of gears are reversing gears, and the position of the first drive motor 111 can be set according to actual needs through the reversing gear.

[0046] Further, for the first lifting assembly 11, please refer to Figure 8 The first lifting component 11 also includes three sensors 114 and a controller. The three sensors 114 are arranged on the bracket 110. The three sensors 114 are arranged on the same vertical plane, and the three sensors 114 are arranged at different heights. The controller is arranged on the bracket 110, and the controller is respectively connected to the three sensors 114 and the first drive motor 111.

[0047] In the present application, the three sensors 114 are displacement sensors 114 corresponding to three different heights. Through the action of the three sensors 114 and the controller, the first lifting component 11 can be lifted and lowered according to a fixed height, that is, the lifting stroke of the first lifting component 11 is limited to avoid the first lifting component 11 from being lifted or lowered insufficiently or excessively during the lifting process, causing the roller brush part 12 in the sweeping or washing mode to fail to work normally or the roller brush part 12 to be damaged by excessive compression with the ground. In addition, when the cleaning device of the cleaning robot is installed on the robot body and used in conjunction with it, the scene sensing function of the robot body itself can enable the first lifting component 11 to automatically adjust the sweeping or washing mode corresponding to the roller brush part 12.

[0048] In the present application, the structure of the first lifting assembly 11 is the same as that of the second lifting assembly 24. The structure and function of the second lifting assembly 24 can refer to the structure and function of the first lifting assembly 11, and will not be described in detail here.

[0049] For the first drive assembly 14, see Figure 3 The first drive assembly 14 includes a second drive motor 140 and a transmission member 141. The second drive motor 140 is arranged at the top of the first shell 10, and the transmission member 141 is arranged on the side of the first shell 10. One end of the transmission member 141 is connected to the second drive motor 140, and the other end of the transmission member 141 extends to the first cavity 100 and is connected to the roller brush member 12. The transmission member 141 can be a belt drive structure, a sprocket chain drive structure or a gear drive structure. By starting the second drive motor 140, the transmission member 141 is driven to rotate, and then the roller brush member 12 is driven to rotate. In addition, the rotation speed of the roller brush member 12 is adjusted by controlling the rotation speed of the second drive motor 140.

[0050] In addition, the first drive component 14 and the second drive component 23 have the same structure. The structure and function implementation of the second drive component 23 can refer to the structure and function implementation of the first drive component 14, and will not be repeated here.

[0051] For the above mentioned waste water box 26, please refer to Figure 5-Figure 7 The second housing 20 is provided with a second mounting opening 201, which is connected to the second cavity 200. A sewage box 26 is provided along the second mounting opening 201 and extends into the bottom of the second cavity 200. The sewage box 26 covers the second mounting opening 201, and the opening of the sewage box 26 is provided below the surface of the extrusion assembly 25 that abuts the compression roller member 21. It should be noted that a sewage outlet 260 is provided at one end of the sewage box 26 that covers the second mounting opening 201. A water pump (not shown) and a sewage tank (not shown) are provided outside the sewage box 26. The water pump is used to pump sewage from the sewage box 26 along the sewage outlet 260 into the sewage tank. In conjunction with the automatic water spraying of the water spray assembly 22, the cleaning device of the cleaning robot can realize the functions of automatic water spraying and automatic sewage recovery.

[0052] In the present application, the installation method of the sewage box 26 is the same as the installation method of the garbage box 13. For the structure and installation method of the sewage box 26, reference can be made to the installation method of the above-mentioned garbage box 13, which will not be repeated here.

[0053] For the above extrusion assembly 25, see Figure 7 The extrusion assembly 25 includes a second elastic member 250 and a wiper member 251.

One end of the wiper member 251 extends to abut the surface of the compression roller member 21.

[0054] In the present application, the elastic force of the second elastic member 250 can keep the wiper member 251 in contact with and press the surface of the roller member 21 at all times, ensuring that all water in the roller member 21 is squeezed out.

[0055] For the above extrusion assembly 25, see Figure 7 The extrusion assembly 25 further includes a guide plate 252 , which is obliquely disposed at the opening of the sewage box 26 , and one end of the guide plate 252 extends to abut against the surface of the compression roller 21 .

[0056] In the present application, the inclined setting of the drain plate 252 can make the sewage produced by the extrusion component 25 flow into the sewage box 26 through the drain plate 252, thereby improving the probability of sewage recovery and reducing the probability of sewage leaking to the ground. In addition, the drainage effect of the drain plate 252 can prevent the sewage squeezed by the extrusion component 25 from directly falling into the sewage box 26 and splashing onto the surface of the roller part 21, thereby preventing secondary pollution of the roller part 21.

[0057] The present invention controls the roller brush member 12 to exert different degrees of compression and deformation on the floor through the first lifting assembly 11, and cooperates with the water spray assembly 22 to spray water or not, and the first driving assembly 14 to drive the roller brush member 12 to operate, so as to enable the cleaning device of the cleaning robot to sweep and wash the floor of the same scene. The second driving assembly 23 drives the roller member 21 to operate, and cooperates with the water spray assembly 22 to control the amount of water sprayed, so as to enable the cleaning device of the cleaning robot to mop and dust push the floor of the same scene. Through the above-mentioned method, the cleaning device of the cleaning robot has the functions of sweeping, washing, mopping and dust pushing, and can complete the cleaning tasks of sweeping, washing, mopping and dust pushing on the same scene, effectively improving the cleaning efficiency of the cleaning device of the cleaning robot, improving the user's convenience, and facilitating the user to use the same device for different cleaning tasks, saving time.
