[0028] See also Figure 1-4 The present invention provides a technical solution: a multifunctional cleaning robot, comprising a shell A1 and a shell B2, wherein the shell A1 and the shell B2 are connected via an electric balance bar 3, and the electric balance bar 3 can be used to realize that the shell A1 rotates around the pin shaft on the shell B2 to realize folding, and a motor mounting plate A103 is installed on one side of the inner part of the shell A1, and a motor A104 is installed on the motor mounting plate A103, and the motor A104 is connected to a ball screw 107 via a coupling 109, and the ball screw 107 is connected to the ball screw 107. A screw slider 108 is threadedly connected, a motor B110 is installed at the bottom of the screw slider 108, a cleaning disc A101 is installed on the main shaft of the motor B110, a centrifugal fan box A1021 is installed inside the cleaning disc A101, a sponge suction cup A102 is installed at the bottom of the centrifugal fan box A1021, the motor A104 is used to realize the movement of the cleaning disc A101 on the ball screw 107, and the centrifugal fan box A1021 is used to work to realize the sponge suction cup A102 adsorbed on the ceiling or glass;

[0029] like Figure 5-6As shown: a cleaning disc B201 and a cleaning disc C202 are arranged at the bottom of the outer shell B2, a centrifugal fan box B2031 is installed inside the cleaning disc B201, a sponge suction cup B203 is installed at the bottom of the centrifugal fan box B2031, a centrifugal fan box C2041 is installed inside the cleaning disc C202, a sponge suction cup C204 is installed at the bottom of the centrifugal fan box C2041, the cleaning disc B201 and the cleaning disc C202 are rotated to scrub the ceiling or glass, and the centrifugal fan box B2031 and the centrifugal fan box C2041 work to enable the sponge suction cup B203 and the sponge suction cup C204 to be adsorbed on the ceiling or the glass.

[0030] like Figure 3-4 As shown: the top of the shell A1 is provided with two grooves A for placing the electric balance rod 3, and one end of the groove A is installed with the electric balance rod connecting rod A105; the top of the shell B2 is provided with two grooves B for placing the electric balance rod 3, and one end of the groove B is installed with the electric balance rod connecting rod B209, and both ends of the electric balance rod 3 are connected with the electric balance rod connecting rod sleeve 301 matching the electric balance rod connecting rod A105 and the electric balance rod connecting rod B209.

[0031] like Figure 4 As shown: four movable pin sleeves B207 are provided on one side of the top of the shell B2, and two movable pin sleeves A106 are provided on one side of the top of the shell A1. The movable pin sleeve A106 is inserted between the two movable pin sleeves B207, so that the center positions of the movable pin sleeve A106 and the movable pin sleeve B207 are in the same straight line, and the movable pin 208 is passed through the movable pin sleeve A106 and the movable pin sleeve B207, and the two ends of the movable pin 208 are fixed with limited blocks.

[0032] The electric balance rod connecting rod sleeve 301 at one end of the electric balance rod 3 is inserted into the electric balance rod connecting rod B209 and can rotate around the electric balance rod connecting rod B209. The electric balance rod connecting rod sleeve 301 at the telescopic end of the electric balance rod 3 is inserted into the electric balance rod connecting rod A105 and can rotate around the electric balance rod connecting rod A105. When the electric balance rod 3 contracts, the movable pin sleeve A106 on the outer shell A1 rotates around the movable pin 208, and the outer shell A1 will be pulled to form a right angle of 90 degrees with the outer shell B2.

[0033] like Figure 6As shown: the motor A104 is bolted to the motor mounting plate A103, the motor B110 is bolted to the bottom of the screw slider 108, the cleaning disc A101 is bolted to the main shaft of the motor B110, the top of the centrifugal fan box A1021 is fixedly connected to the inner top of the cleaning disc A101, and the cleaning disc A101 and the centrifugal fan box A1021 rotate around the main shaft of the motor B110. When the sponge suction cup A102 is not adsorbed, the motor B110 rotates to drive the cleaning disc A101 and the sponge suction cup A102 to rotate. Since the sponge suction cup A102 is adsorbed on the ceiling or glass and is fixed, and when the sponge suction cups B203 and C204 are not working, the motor B110 makes the entire robot perform a steering operation under the action of the reaction force.

[0034] This drives the motor B110 and the screw slider 108 connected to the cleaning disc A101 to rotate. When the sponge suction cup B203 and the sponge suction cup C204 are not working, the rotation of the motor B110 can drive the entire robot to perform a steering operation.

[0035] A motor C206 is installed on the top of the cleaning disc B201 and the cleaning disc C202. The motor C206 is installed on the motor mounting plate B210 at the bottom of the shell B2 by bolts. When the motor C206 works, it drives the cleaning disc B201 and the cleaning disc C202 to rotate; the centrifugal fan box B2031 and the centrifugal fan box C2041 are installed on the inner top of the cleaning disc B201 and the cleaning disc C202. When the sponge suction cup B203 and the sponge suction cup C204 are sucked and motionless, the cleaning disc B201 and the cleaning disc C202 and the sponge suction cup B203 and the sponge suction cup C204 remain motionless. When the motor C206 is working, the cleaning disc B201, the cleaning disc C202, the sponge suction cup B203 and the sponge suction cup C204 rotate at the same time, thereby performing cleaning work.

[0036] like Figure 4-5 As shown: the cleaning disc B201 and the cleaning disc C202 are both provided with belt grooves, and the cleaning disc B201 and the cleaning disc C202 are connected by a belt 205, so as to enable the cleaning disc B201 and the cleaning disc C202 to rotate synchronously.

[0037] The centrifugal fan box A1021 is fixedly connected to the sponge suction cup A102 through a sealing gasket and bolts, the air inlet of the centrifugal fan box A1021 is connected to the sponge suction cup A102, the centrifugal fan box B2031 is fixedly connected to the sponge suction cup B203 through a sealing gasket and bolts, the air inlet of the centrifugal fan box B2031 is connected to the sponge suction cup B203, the centrifugal fan box C2041 is fixedly connected to the sponge suction cup C204 through a sealing gasket and bolts, and the air inlet of the centrifugal fan box C2041 is connected to the sponge suction cup C204. The centrifugal fan box A1021, the centrifugal fan box B2031 and the centrifugal fan box C2041 are used to work to realize the adsorption work of the sponge suction cup A102, the sponge suction cup B203 and the sponge suction cup C204, and the sponge suction cup A102, the sponge suction cup B203 and the sponge suction cup C204 can also adsorb rough and uneven walls.

[0038] Centrifugal fans are installed in the centrifugal fan box A1021, the centrifugal fan box B2031 and the centrifugal fan box C2041. A control box 4 is also installed on the outer casing B2. A battery and a control main board are installed inside the control box 4. The control main board is electrically connected to the motor A104, the motor B110, the motor C206, the centrifugal fan and the electric balance bar 3 respectively. The control main board is used to control the motor A104, the motor B110, the motor C206, the centrifugal fan and the electric balance bar 3 to power on and operate.

[0039] A scrubbing cloth is installed at the bottom of the cleaning disc A101, the cleaning disc B201 and the cleaning disc C202. The scrubbing cloth rotates by rotating the cleaning disc A101, the cleaning disc B201 and the cleaning disc C202, thereby scrubbing the ceiling or the glass.

[0040] Working principle: A multifunctional cleaning robot, when in use, by installing a scrubbing cloth on the bottom of the cleaning disc A101, the cleaning disc B201 and the cleaning disc C202, the robot is adsorbed on the ceiling or glass through the sponge suction cup A102, the sponge suction cup B203 and the sponge suction cup C204. When the robot needs to move forward and backward, the centrifugal fan box A1021 is controlled by the main board to stop working, and the sponge suction cup A102 has no adsorption capacity, and then the motor A104 is controlled to work to drive the ball screw 107 to rotate, so that the screw slider 108 drives The cleaning disc A101 moves forward, and when it moves forward, the motor B110 drives the cleaning disc A101 to rotate so that the scrubbing cloth at the bottom of the cleaning disc A101 scrubs the ceiling or glass, completing the purpose of scrubbing while moving forward. When it moves to a suitable position, the centrifugal fan box A1021 works so that the sponge suction cup A102 is adsorbed on the ceiling or glass. At the same time, the centrifugal fan box B2031 and the centrifugal fan box C2041 are controlled to stop working, and the sponge suction cups B203 and C204 are separated from the ceiling or glass, and then the sponge suction cups A103 and A104 are used to clean the ceiling or glass. The motor A104 is used to rotate in the opposite direction, thereby driving the ball screw 107 to rotate in the opposite direction, and the screw slider 108 drives the entire device to move forward. When moving forward, the motor C206 is used to drive the cleaning discs B201 and C202 to rotate, so that the scrubbing cloths at the bottom of the cleaning discs B201 and C202 can scrub the ceiling or glass, thereby achieving the purpose of scrubbing while moving forward. The paths of the cleaning discs A101, B201 and C202 are exactly the paths for scrubbing the ceiling or glass. When turning is required, the cleaning discs A101, B201 and C202 are used to scrub the ceiling or glass. The sponge suction cup A102 is adsorbed on the ceiling or glass and does not move, and the motor B110 is used to work. Since the motor B110 is connected to the entire robot body, the main shaft of the motor B110 and the centrifugal fan box A1021 on the sponge suction cup A102 are fixed together. When the sponge suction cup A102 is adsorbed and does not move, and the motor B110 is working, the body is driven to rotate by the reaction force, thereby achieving a change in direction. The steering angle can also be controlled by a sensor, so that the robot can move back and forth, left and right on the ceiling or glass to achieve scrubbing of the ceiling or glass.

[0041] Example 1: Cleaning the ceiling, the specific process is as follows:

[0042] 1. Adsorb to the wall;

[0043] The outer shell A1 and the outer shell B2 are folded 90 degrees by the electric balance bar 3, so that the sponge suction cup A102 on the outer shell A1 is attached to the wall, and the centrifugal fan box A1021 is started, and the outer shell B2 faces the ceiling to ensure that the outer shell A1 of the robot is completely adsorbed; then the sponge suction cups B203 and C204 at the bottom of the outer shell B2 are adsorbed, and the sponge suction cup A102 is not adsorbed, and the motor A104 is used to drive the screw slider 108 to move on the ball screw 107 so that the cleaning disc A101 moves forward, and then the sponge suction cup A102 is adsorbed, and the sponge suction cups B203 and C204 are not adsorbed, and then the motor A104 is reversed to drive the entire robot forward, so as to realize step-by-step upward movement. When moving from the ground to the wall, the electric balance bar 3 is always adjusting the angle between the outer shell A1 and the outer shell B2.

[0044] 2. Move to the ceiling;

[0045] After step 1 is completed, the robot will approach the ceiling through the mobile module, and measure the distance between the robot and the ceiling through the distance sensor installed on the robot shell to ensure that this distance is sufficient for the maximum displacement. At this time, the sponge suction cup A102 is reset to the center position to leave enough distance for movement, and the machine is folded 90 degrees through the electric balance bar 3, so that the sponge suction cup B203 and sponge suction cup C204 face upward, and the robot moves so that the sponge suction cup B203 and sponge suction cup C204 are close to the ceiling. At this time, the sponge suction cup A102 is controlled to alternately adsorb and rotate with the sponge suction cup B203 and sponge suction cup C204 to achieve the purpose of differential movement. When the distance between the shell B2 and the wall is enough to accommodate the shell A1, the electric balance bar 3 is started to make the sponge suction cup A102 tightly attached to the ceiling, and the conversion from the wall to the ceiling is completed.

[0046] 3. Clean the ceiling;

[0047] The complete cleaning process is completed by the cleaning module (cleaning disc A101, cleaning disc B201, cleaning disc C202), the adsorption module (sponge suction cup A102, sponge suction cup B203 and sponge suction cup C204) and the moving module (motor A104, ball screw 107, screw slider 108). When the moving module is running, sponge suction cup A102 works alternately with sponge suction cup B203 and sponge suction cup C204, and the cleaning disc on the non-working side rotates to clean. The cotton cloth on the cleaning disc A101 is used for the first cleaning, and the cleaning discs B201 and C202 are used for the second cleaning. When the sponge suction cup A102 is reset when it touches the wall, the motor of the cleaning disc A101 is started to drive the entire robot to rotate, and the rotation angle is sensed by the position sensor, and the cleaning continues after the direction is changed. In this way, the entire ceiling is cleaned.

[0048] 4. After cleaning, return to the low wall;

[0049] After cleaning is completed, the robot will move to the edge of the wall, with the shell B2 facing the wall, reset the suction cup to the middle position, fold the shell B2 to 90 degrees, start the mobile module to make the sponge suction cup B203 and sponge suction cup C204 close to the wall, and move a certain distance at a differential speed to reset the shell A1. Complete from the ceiling to the wall, and then return to the low wall through the mobile module.

[0050] Example 2: The specific process of cleaning glass is as follows:

[0051] 1. The process from the ground to the glass is the same as the crawling method for cleaning the ceiling in Example 1.

[0052] 2. Clean the glass;

[0053] Replace the cotton cloth on the cleaning disc A101 with a dry cotton cloth, and install a wiper on the outer shell A1. After the cleaning disc and the wet cotton cloth complete the cleaning, the dry cloth and the wiper are used for dehumidification. When the robot moves forward, the sponge suction cup A102 works alternately with the sponge suction cups B203 and C204. During the process, the cleaning disc on the non-working side rotates to achieve cleaning. The cotton cloth on the cleaning disc A101 performs the first cleaning, and the cleaning discs B201 and C202 perform the second cleaning. When the cleaning of one side of the glass is finished, the sponge suction cup A102 absorbs the glass, and the motor B110 on the cleaning disc A101 is started to drive the entire robot to rotate. The position sensor senses the rotation angle, and the robot continues to clean after reversing, thereby cleaning the entire glass.

[0054] The above embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
