Compared with the traditional restaurant cleaning robot technology, the restaurant cleaning robot designed in the present invention is composed of a driving mechanism, a traveling mechanism, a wiping device, an adjusting device, and a dust collecting device, and has a walking function, a dust removing function, a wiping function and an adjusting function.

In the present invention, the traveling mechanism has a walking function; the functional motor installed in the traveling mechanism can provide power to the restaurant cleaning robot; the function of the vacuum pump is to provide a negative pressure to the dust box; and the dust box can absorb the collected dust. The storage tank is convenient for uniform cleaning; the water tank can supply the water source to the wiping device; the PLC chip in the functional mechanism of the invention can control the rotation and rotation of the walking wheel, thereby achieving the purpose of controlling walking and changing direction, so that the cleaning robot can reach the need to clean up The place; the effect of intelligent cleaning robots. In the wiping device of the present invention, the ground can be wiped. During the wiping process, the water in the water storage tank in the walking structure flows into the wiping block through the outlet pipe and the first inlet pipe, so that the wiping block is semi-dry and semi-wet, and is cleaned. After the robot is vacuumed, the ground is wiped and cleaned by the wiping block to make the floor cleaner; the dust collecting device designed in the invention has the function of vacuuming; the lower end of the dust box has a plurality of dust collecting holes in the circumferential direction, and the function is to vacuum the dust.

Press to keep the pressure inside the vacuum box constant. Cleaned up The dust is sucked into the dust box through the dust suction hole, and the dust in the dust box is moved to the dust box in the walking structure through the first dust suction pipe and the second dust suction pipe; thereby achieving the effect of vacuum cleaning .

The function of the above-mentioned adjusting mechanism is that when the clearing robot touches the table leg during the working process, the driving motor drives the screw to rotate, and both ends of the screw are mounted on the end faces of the supporting block and the adjusting groove; the screw does not rotate at the same time. Moving and screwing between the screw and the nut, the nut moves while the screw rotates. When the nut moves into contact with the second telescopic rod, the nut presses the second telescopic rod so that the second telescopic rod One end moves toward one end of the adjusting block, and when one end of the second telescopic rod moves to match the groove on the nut, one end of the second telescopic rod is caught in the groove on the nut; then the nut moves to bring the adjusting block Moving so that the table legs are just caught in the semicircular groove of one of the two adjustment blocks; at this time, because the semicircular groove of the adjustment block is bound by the legs, the walking structure is driven laterally toward the table legs by the legs; A reaction force is applied to the second housing to cause it to rotate; while the second housing rotates, the first housing is driven around the dining table by four tension springs Rotating; after the second housing is rotated by ninety degrees, the second housing continues to rotate by the force of the scroll spring, and the first housing surrounds the table by four tension springs while the second housing rotates The foot continues to rotate until it is turned to the other side of the table leg, thereby achieving the purpose of cleaning the table legs. After the cleaning is completed, since the clearing robot will continue to move forward, at this time, the semicircular groove on the adjusting block has been rotated to the other side of the leg; then the nut will gradually move to the original position under the action of the driving motor. During the moving process, the nut passes the second telescopic rod, so that the second telescopic rod moves out of the nut along the curved portion of the upper groove of the nut, and after the second telescopic rod is disengaged from the nut, the adjustment block is restored by the tension spring. The force returns to the starting position; the nut also returns to its original position. The second casing designed by the invention is rotated by ninety degrees by the action of the restaurant table leg and the first casing, and then continues to rotate by ninety degrees by the force of the scroll spring; since the scroll spring is only in the second casing When the rotation angle reaches 90 degrees, the second housing continues to rotate in the original direction, and the second housing is rotated by the scroll spring to rotate in the opposite direction; the present invention rotates by designing the second housing. At the next ninety degrees, the second housing can rotate the first housing around the restaurant table legs by the tension spring while rotating twice; thereby cleaning the dust around the table legs.

In the invention, the base plays a supporting role on the fixed shaft; and the first limiting block mounted on the upper side thereof has a fixed function; one end of the clamping block is installed on the inner side of the second spring cavity, and is mounted on the clamping block and The compression spring between the second spring chambers can provide a restoring force to the block when the compression state is in a compressed state; the lower end of the block has a first limit groove, and the push block can pass from the first limit groove from one side of the block Moving to the other side; the lower end of the block is mounted with a compression block; one end of the first telescopic rod is mounted inside the first spring cavity; when the compression spring installed between the first spring cavity and the first telescopic rod is in a compressed state The first telescopic rod can provide a restoring force; the upper end of the first telescopic rod is provided with a guiding arc plate, and when the block moves toward the inner side of the second spring cavity, the compressing block will push the guiding arc plate to move; The plate drives the first telescopic rod to move to the inner side of the first spring chamber; the second limiting block acts as a limit for the card block; the second limiting block acts as a limit for the first telescopic rod The scroll spring mounted between the sleeve and the first annular post can provide a restoring force to the sleeve. The width of the pushing block designed by the invention is the same as the width of the first limiting slot, and the upper end surface of the pushing block is flush with the upper side of the first limiting slot, so that the pushing speed can be smoothly at the first limit. Move in the bit slot.

When the cleaning robot is working, the compression spring installed between the first telescopic rod and the first spring chamber is in a freely telescopic state, and the compression spring installed between the block and the second spring chamber is in a freely telescopic state, and the scroll spring is at a free state; the block is located on the front side of the first telescopic rod in a circumferential clockwise direction; the first telescopic rod is in contact with the first limit block; one of the four push blocks is in contact with the block, and the push block The first limit slot on the block is misaligned with each other; the cleaning robot is controlled by the function motor and the PLC chip in the traveling mechanism to perform mobile cleaning; when the cleaning robot touches the table leg on the ground during the cleaning process, the table leg will Blocking the cleaning robot from advancing, the adjusting mechanism mounted on the lower end of the first housing causes the driving motor control screw to cause the table legs to be caught in the semi-circular groove on the adjusting block; at this time, the table leg is a reaction to the second housing on the cleaning robot The second housing rotates because the four push blocks are mounted inside the second housing, so the second housing rotates while pushing four pushes The block rotates; at this time, one of the four push blocks is in contact with the block, that is, the push block pushes the block to rotate around the fixed axis; and the compressed block mounted on the lower side of the block also rotates. Because one end of the scroll spring is mounted on the sleeve, the other end is mounted on the inner circular surface of the first annular column groove; and the block rotates while driving the first ring column to rotate, the first ring column and the shaft The sleeve is installed by a bearing; the second end of the bearing is fixedly mounted with a second annular column, and the second annular column is mounted with a first telescopic rod, the first telescopic rod is in contact with the first limiting block, and the first limiting block is limited a telescopic rod moves to thereby restrict the movement of the second annular column and the sleeve; when the relative rotation between the sleeve and the first annular column occurs, the scroll spring is subjected to an outward pulling force of the first annular column; After the block rotates at a certain angle, it will contact the second limit block, and the other of the four blocks moves to a position close to the first telescopic rod; since the contact between the second limit block and the block is a circle Arc, so the block and the first While the limit block is in contact, because the second limit block will give it a reaction force, the block will move to the side close to the fixed axis under the reaction force; during the movement, the compression block will push the first installation. The guiding arc plate on the telescopic rod moves toward a side close to the fixed shaft, and the guiding arc plate moves while driving the first telescopic rod; during the movement of the first telescopic rod, the other pushing block gradually approaches the first telescopic rod and The circumferential direction is located in the clockwise direction on the rear side of the first telescopic rod; as the contact area of the first limiting slot port and the push block increases in the movement of the block; the first telescopic rod gradually moves away from the control of the first limit block, And the other pushing block gradually moves from one side of the first limiting block to the other side of the first limiting block through the square notch on the first limiting block; when the pushing block moves to the square in the first limiting slot Partially in full contact; the first telescopic rod has been completely out of control of the first limit block while the other push block has also moved to the front side of the first telescopic rod; at this time due to the installation in the first spring chamber and the second spring chamber compressed spring The first telescopic rod and the block will move away from the fixed axis. At the same time as the movement of the block and the first telescopic rod, the push block gradually moves out of the card from the square shape portion of the first limit groove through the inclined portion. Block, located on the front side of the block; In the force of the scroll spring, the first telescopic rod will push another push block located at the front thereof to move; thereby driving the second outer casing to rotate; sequentially driving, the second outer casing will be in a state of constant rotation; the second outer casing is rotated At the same time, the first outer casing is driven by four tension springs mounted between the second outer casing and the first outer casing, while the first outer casing can be rotated around the dining table leg while moving; through the dust suction device while rotating And wiping the device to clean both sides of the leg; after the cleaning is completed, since the cleaning robot has moved to the other side of the leg, the leg does not affect the movement of the cleaning robot; the cleaning robot can continue to the other ground The dust is cleaned up.
