Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

In the prior art, the problem to be solved of the existing table cleaning robot is that the table is cleaned by wiping the table with a cleaning brush and a cleaning agent by the robot. However, in practice, this is only one of the steps of cleaning the dining table after people have a meal, and the step of cleaning the dining table in the real sense of life should include picking up dishes, sweeping the garbage on the dining table, and wiping the dining table clean. The main technical means of the robot is to clean the table top through a dust suction device and then mop the floor through driving a brush or a rag and the like. However, such a robot for cleaning a table top cannot be applied to a table for cleaning the garbage on the table because the garbage on the table includes large bones and the dust suction device cannot suck the bones; or for garbage which occupies liquid, such as fishbone, the garbage can be adsorbed on the table top and can not be sucked into the garbage cavity of the robot in a suction mode. Therefore, the utility model provides an do not rely on suction device to adsorb rubbish, but clear up dining table rubbish through the mode of sweeping rubbish to solve the problem that suction device can't clear up big rubbish such as bones on the dining table.

As shown in fig. 1 to 5, the dining table cleaning robot comprises a first driving device, and is further provided with an arc-shaped annular garbage cavity 31, wherein at least one end of the annular garbage cavity 31 is communicated with the outside; the annular garbage cavity 31 is internally provided with a rotating block 10 driven by a first driving device, the lower part of the rotating block 10 is provided with a sweeping and brushing part for sweeping garbage, and the rotating block 10 is used for sweeping the garbage into and out of the annular garbage cavity 31 through forward rotation and reverse rotation matching under the driving of the first driving device. The dining table cleaning robot provided by the utility model, as the sweeping brush part at the lower part of the rotating block 10 is driven by the first driving device to sweep the garbage into the annular garbage cavity 31, the first driving device is used as a power device capable of driving the part to rotate, and the output driving force is far larger than the suction force of the suction device for dust collection; moreover, the garbage is sucked into the annular garbage cavity 31 by the suction device, the gravity of the garbage itself needs to be overcome, and the garbage can be swept into the annular garbage cavity 31 by the suction device, only the friction force between the garbage and the table top needs to be overcome, for the garbage with large volume and large mass of large bones, the gravity is far larger than the friction force between the garbage and the table top, so even if the suction device sucks the large dining table garbage, the dining table cleaning robot provided by the utility model can clean the garbage in a sweeping way, for the garbage with small pieces, the garbage can be cleaned naturally in a sweeping way, therefore, basically, the dining table cleaning robot provided by the utility model can clean all types of garbage with fixed shapes on the dining table, the garbage can be cleaned by the robot, and the trouble of manually cleaning the garbage dining table is avoided, the garbage cleaner saves time and trouble, and is particularly significant for restaurants and other places requiring more hands and more time to clean the garbage on the dining table.

It should be noted that the first driving means may be an electric motor, a steering engine or other means for driving the component in forward and reverse rotation, as is conventional to those skilled in the art. The annular garbage chamber 31 may be formed by integrally forming a hollow space in the robot housing 30, or may be a tank body on which a sealing cover is mounted.

Further, one end of the annular garbage cavity 31 is an inlet communicated with the outside, the other end of the annular garbage cavity 31 is an outlet provided with an openable and closable closing door, and the closing door is used for preventing garbage from being swept out from the outlet when the first driving device sweeps the garbage into the annular garbage cavity 31 from the inlet through positive rotation. The working principle is as follows: the first driving device is made to rotate forwards, the rotating block 10 is rotated into the annular garbage cavity 31 from the inlet of the annular garbage cavity 31 to sweep garbage into the annular garbage cavity 31, then the first driving device is made to rotate backwards, the garbage exits from the annular garbage cavity 31 to the outside of the annular garbage cavity 31 along the original movement track, and the process is repeated. When the garbage in the annular garbage cavity 31 needs to be dumped, the closing door is opened, the first driving device is driven to rotate forwards, the rotating block 10 enters from the inlet of the annular garbage cavity 31 and exits from the outlet of the annular garbage cavity 31, and then the garbage in the annular garbage cavity 31 can be swept out from the outlet of the annular garbage cavity 31. It should be noted that in order to leave a space for storing garbage in the annular garbage chamber 31, the rotating block 10 rotates only an angle when rotating forward, and does not rotate to abut against the closing door and stop. For example, a motor is used as the first driving device, and the speed of the motor driving the rotating block 10 to rotate is determined, so that the rotating angle of the rotating block 10 can be controlled only by controlling the actuation time of the motor, and the moving distance of the rotating block 10 in the annular garbage cavity 31 can be controlled.

Furthermore, two inlets and outlets communicated with the outside are arranged at two ends of the annular garbage cavity 31, one inlet and outlet is used for being matched with the sweeping part to sweep garbage into the annular garbage cavity 31 when the rotating block 10 rotates forwards for an angle, and the other inlet and outlet is used for being matched with the sweeping part to sweep garbage into the annular garbage cavity 31 when the rotating block 10 rotates backwards for an angle. The working principle is as follows: the initial position of the rotating block 10 does not actually affect the working process of the present technical solution, however, for example, the initial position of the rotating block 10 is in the annular garbage chamber 31, the first driving device is made to rotate reversely, the rotating block 10 rotates out from the first inlet/outlet of the annular garbage chamber 31 and rotates into the annular garbage chamber 31 again from the second inlet/outlet, and this process sweeps the annular garbage chamber 31 into the annular garbage chamber 31 from the second inlet/outlet; then, the first driving device is made to rotate reversely, the rotating block 10 rotates out of the annular garbage cavity 31 from the second inlet/outlet and rotates into the annular garbage cavity 31 from the first inlet/outlet, and in the process, the garbage on the table top is swept into the annular garbage cavity 31 from the first inlet/outlet. It should be noted that, in order to leave a space for storing garbage in the annular garbage chamber 31, the rotating block 10 rotates only one angle in the forward rotation and reverse rotation, and does not stop after rotating one circle. For example, the rotating block 10 may only rotate to a position just before entering the first inlet/outlet and the second inlet/outlet, and thus, there may be more space for storing garbage. A motor can be used as the first driving device, and the speed of the motor driving the rotating block 10 to rotate is determined, so that the rotating angle of the rotating block 10 can be controlled only by controlling the actuating time of the motor, and the moving distance of the rotating block 10 in the annular garbage cavity 31 can be controlled. When the garbage needs to be dumped, the first driving device is only required to control the rotating block 10 to rotate for a circle (which can be forward rotation or reverse rotation), and the garbage in the annular garbage cavity 31 can be swept out of the annular garbage cavity 31 from the inlet and the outlet of the annular garbage cavity 31.

Further, the annular waste chamber 31 is substantially in the shape of a broken ring. The first drive means mounting portion 20 may be located centrally of the annular waste chamber 31. As a whole, the chassis of the robot housing 30 is circular, and the first driving device mounting portion 20 is disposed at the center of the circle, so that the rotating block 10 is driven to rotate in the circumferential direction. It is easy to think that, in order to prevent the rubbish in the annular rubbish cavity 31 from entering the first driving device installation portion 20, a detachable cover body is arranged on the first driving device installation portion 20, the first driving device can be installed after the cover body is detached, and then the cover body is installed, so that the rubbish in the annular rubbish cavity 31 can be prevented from accidentally entering the first driving device installation portion 20. Preferably, the height of the cover corresponds to the height of the annular waste chamber 31 to prevent waste from accumulating on the cover, although not entering the first drive assembly mounting portion 20.

Further, the rotating block 10 is substantially fan-shaped, the narrow end of the rotating block 10 is used for connecting the first driving device, and the shape of the wide end of the rotating block 10 is matched with the shape of the annular garbage cavity 31. Since the annular garbage cavity 31 is annular, and the radius of each position in the annular garbage cavity 31 is equal, the rotating block 10 can be designed into a fan shape, so that no matter where the rotating block 10 rotates, the side wall of the rotating block 10 can be rotatably abutted against the side wall of the annular garbage cavity 31. If the side wall of the rotating block 10 is not rotatably abutted against the side wall of the annular garbage chamber 31, a gap exists between the side wall of the rotating block 10 and the side wall of the annular garbage chamber 31, and garbage is likely to be accumulated in the gap, so that the garbage cannot be completely and thoroughly cleaned out of the annular garbage chamber 31 when the garbage is dumped.

Further, the annular waste chamber 31 is substantially in the shape of an elliptical ring with a gap at the end, narrow at both sides and wide at both ends. The first drive means mounting portion 20 may be located centrally of the annular waste chamber 31. As a whole, the chassis of the robot housing 30 is oval, the first driving device mounting portion 20 is disposed at the center of the annular garbage chamber 31, and the first driving device is convenient for driving the rotating block 10 to rotate. It is easy to think that, in order to prevent the rubbish in the annular rubbish cavity 31 from entering the first driving device installation portion 20, a detachable cover body is arranged on the first driving device installation portion 20, the first driving device can be installed after the cover body is detached, and then the cover body is installed, so that the rubbish in the annular rubbish cavity 31 can be prevented from accidentally entering the first driving device installation portion 20. Preferably, the height of the cover corresponds to the height of the annular waste chamber 31 to prevent waste from accumulating on the cover, although not entering the first drive assembly mounting portion 20.

Furthermore, the rotating block 10 is an extensible member 210 which can be extended and retracted along the radial direction of the annular garbage cavity 31, one end of the extensible member 210 is connected with the first driving device, and the other end of the extensible member abuts against the side wall of the annular garbage cavity 31; an arc-shaped guide plate 233 is further disposed at the notch of the annular garbage chamber 31, and the guide plate 233 is used for guiding the telescopic member 210 which is turned out from one port of the annular garbage chamber 31 and making it reenter the annular garbage chamber 31 from the other port. The extension member 210 may be a plurality of separate blocks connected by elastic members, and the elastic blocks may be springs, elastic columns, etc. The technical scheme is designed for matching with an oval chassis of a robot shell 30, in the scheme, as the annular garbage cavity 31 is oval, the radius of each part is not equal, a rotating block 10 with a fixed radius cannot be kept against the side wall of the annular garbage cavity 31, and therefore the garbage in the cavity cannot be thoroughly swept out and dumped when the garbage in the annular garbage cavity 31 is dumped. For this reason, the solution is provided by replacing the rotating block 10 with a telescopic member 210, when the telescopic member 210 rotates in a narrow position in the annular garbage chamber 31, the telescopic member 210 will contract to adapt to the width of the annular garbage chamber 31, and when the telescopic member 210 rotates in a wide position in the annular garbage chamber 31, the telescopic member 210 will expand to adapt to the width of the annular garbage chamber 31. After the telescopic member 210 is rotated out from one port of the annular garbage chamber 31, in order to avoid that the telescopic member 210 is naturally extended and cannot enter the annular garbage chamber 31 from the other port of the annular garbage chamber 31 when the telescopic member is rotated to the other port of the annular garbage chamber 31, a guide plate 233 is arranged, the guide plate 233 is in an arc shape corresponding to an elliptical robot chassis, after the telescopic member 210 is rotated out from the annular garbage chamber 31, the end part of the telescopic member 210 abuts against the guide plate 233, and therefore the telescopic member 210 cannot be extended too long and cannot enter the annular garbage chamber 31 again after being rotated out from the annular garbage chamber 31.

Further, the lower portion of the rotating block 10 is provided with a annual ring-shaped accommodating groove 12, the brushing portion is provided with a plurality of rows of brushes 11 radially arranged in the accommodating groove 12, and the accommodating groove 12 is used for accommodating the brushes 11 bent by the bottom of the annular garbage cavity 31 when the rotating block 10 enters the annular garbage cavity 31. As shown in fig. 5, a plurality of rows of brushes 11 may be radially arranged, when cleaning, the first row of brushes 11 contacting the table top garbage first cleans the garbage, the garbage which cannot be cleaned by the first layer of brushes 11 is cleaned by the next layer of brushes 11, and the table top is cleaned layer by the brushes 11, so that substantially all the table top garbage can be cleaned. Because there is certain clearance in robot housing 30 and desktop, therefore brush 11 when the turning block 10 moves out annular rubbish chamber 31, brush 11 need protrusion in robot housing 30's chassis just can guarantee can with the desktop contact and can sweep the rubbish of desktop, therefore, when turning block 10 rotated into annular rubbish chamber 31, if brush 11 was directly pressed between turning block 10 and annular rubbish chamber 31 diapire, brush 11 is easily buckled and warp, make it also unable straightening contact the desktop and clean rubbish when turning block 10 rotated out annular rubbish chamber 31, and the brush hair on the brush 11 drops because frequently extruded easily. Therefore, the annual ring-shaped storage groove 12 is provided to correspondingly store a plurality of rows of radially arranged brushes 11, and when the rotating block 10 enters the annular garbage cavity 31, the brushes 11 are slightly bent and stored in the storage groove 12; when the rotating block 10 is rotated out of the annular garbage chamber 31, the brush 11 is extended and straightened out of the receiving groove 12, thereby contacting the table top and sweeping the garbage. The brush 11 does not have a great influence on the life thereof because the amount of bending deformation is small when stored and straightened.

Further, the dining table cleaning robot further comprises a robot housing 30, the annular garbage cavity is arranged in the robot housing 30, a differential wheel set 43 and a driven wheel 42 are arranged at the bottom of the robot housing 30, and a second driving device for driving the differential wheel set 43 to do differential motion is further arranged on the dining table cleaning robot. The second driving means may be arranged in the center of the annular waste chamber 31, i.e. the driving means mounting portion 20, which may make the overall structure compact. The second drive means may be a motor or a device commonly used by those skilled in the art to impart differential motion to the differential wheel set 43. The differential wheel set 43 is at least two differential wheels, which can be arranged one left side and one right side, and the speeds of the two wheels are different, one is high, the other is low or non-actuated, so that the high-speed wheels can drive the dining table cleaning robot to turn to the side of the low-speed or non-actuated wheels.

Further, a driving device mounting part 20 which is approximately in a vertical cylindrical shape is arranged at the center of the annular garbage cavity 31, and a second driving device is arranged in the driving device mounting part 20; the bottom of the driving device mounting portion 20 is higher than the bottom of the robot housing 30 to form a recess for mounting the differential wheel set 43 and bringing the bottom of the robot housing 30 closer to the table top; driven wheel mounting parts 41 extend outwards from both sides of the robot housing 30, and two driven wheels 42 are mounted on the two driven wheel mounting parts 41, respectively. It should be noted that the driven wheel mounting portion 41 may extend outward from one side of the robot housing 30, and the driven wheel 42 may be mounted on the driven wheel mounting portion 41.

Since the robot housing 30 is a circular or elliptical mechanism having a curvature as described above, if the differential wheel set 43 and the driven wheel 42 are directly disposed on one side of the robot housing 30, the differential wheel set 43 and the driven wheel 42 may be interfered by a wider portion of the robot housing 30 to block the movement of the differential wheel set 43 or the driven wheel 42, and the differential wheel set 43 may abrade the robot housing 30, so that the extended driven wheel mounting portion 41 is disposed to prevent the driven wheel 42 from interfering with the robot housing 30; the differential wheel set 43 is installed in the recess to avoid interference with the robot housing 30 having an arc structure, and only a part of the differential wheel set 43 protrudes out of the recess, so that the chassis height of the robot housing 30 can be reduced, and garbage can be swept into the annular garbage chamber 31 more conveniently.

Further, the port of the annular garbage chamber 31 is provided with a slope 32 for sweeping the table top garbage into the annular garbage chamber 31. Although the differential wheel set 43 can be disposed in the recess to reduce the height of the chassis of the robot housing 30 by the above-mentioned technical solution, since the dining table cleaning robot is driven to move by the differential wheel set 43, the bottom of the robot housing 30 is necessarily spaced from the table top, and during cleaning, some small garbage is easily swept into the gap between the bottom of the robot housing 30 and the table top, and is not swept into the annular garbage chamber 31. In order to clean the table garbage more thoroughly, a slope 32 is arranged at the port of the inlet and the outlet of the annular garbage cavity 31, and the table garbage is swept to the slope 32 by the cleaning part and then enters the annular garbage cavity 31 from the slope 32. The slope 32 can be designed into an acute angle shape, only the angle tip part extends to the height capable of contacting with the table top, so that the contact surface of the slope 32 and the table top is only a straight line, the friction force between the slope 32 and the table top is greatly reduced compared with the contact surface, in other words, the movement of the table cleaning robot is not obstructed by the existence of the slope 32, and small garbage can be thoroughly swept into the annular garbage cavity 31 through the slope 32 by the sweeping part, so that the table cleaning robot can clean the garbage on the table top more thoroughly.

Furthermore, the dining table cleaning robot is also provided with a visual sensor for detecting garbage and a control system for receiving signals of the visual sensor to control the dining table cleaning robot to clean. When the dining table cleaning robot detects garbage through the vision sensor, signals are fed back to the control system, and the dining table cleaning robot can move past and clean the garbage. The visual sensor is a conventional prior art and can be simply formed by programming on a single chip microcomputer.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
