[0013] The utility model provides a spray arm for a cleaning machine. Compared with the prior art, it has the following beneficial effects:

[0014] 1. A spray arm for a cleaning machine, which drives the bottom active connecting rod to rotate through a motor. The transmission rod connected to the active connecting rod is driven by the active connecting rod to make a reciprocating motion. Since one end and the middle part of the transmission rod are movably connected to the passive connecting rod and the second linkage rod, the bottom second transmission rod can be driven to make the same reciprocating motion, and the spray part at the bottom of the lower connecting rod movably connected to the top can make a circular motion at one end of the lower connecting rod, which can expand the spraying area of the spray arm, improve the cleaning efficiency of larger cleaning objects, and have a wider spraying area.

[0015] 2. A spray arm for a cleaning machine, through the second motor arranged at the bottom of the lower connecting piece, can drive the rotating piece to rotate around the upper connecting block and the lower connecting piece while the motor drives the active connecting rod to rotate. Since the linkage rod and the third lower connecting rod are movably connected inside the connecting blocks and the lower connecting blocks protruding from the side of the rotating piece, the entire robotic arm can be driven to rotate to expand the spraying area, and the cleaning dead corners at both ends of the cleaning machine can be taken into account, avoiding incomplete cleaning due to the relatively fixed spraying position of the robotic arm.

A spraying member 112 is fixedly connected to the bottom of the lower connecting rod 111. The transmission rod 15 and the second transmission rod 18 perform a reciprocating motion under the drive of the driving connecting rod 14. While performing the reciprocating motion, the transmission rod 15 and the second transmission rod 18 cross each other, causing the third linkage rod 110 connected to the middle and the lower connecting rod 111 connected to the bottom to rotate, so that the spraying member 112 fixedly connected to the bottom of the lower connecting rod 111 rotates around the connection point of the third linkage rod 110 and the second transmission rod 18, and sprays water on the surface of the object to be cleaned.

[0023] Please refer to Figure 1 , 3 -4, the rotating assembly 2 includes a rotating member 21. A connecting block 23 protrudes from the top side of the rotating member 21.

[0025] During use, when it is necessary to clean an article, first, the motor 13 drives the bottom active connecting rod 14 to rotate. The transmission rod 15 connected to the active connecting rod 14 is driven by the active connecting rod 14 to perform a reciprocating motion. Since one end and the middle part of the transmission rod 15 are movably connected with the passive connecting rod 17 and the second linkage rod 19, the bottom second transmission rod 18 can be driven to perform the same reciprocating motion. While the transmission rod 15 and the second transmission rod 18 are performing the reciprocating motion, they perform staggered motions at both ends of the passive connecting rod 17, the second linkage rod 19 and the third linkage rod 110, driving the spraying member 112 at the bottom of the lower connecting rod 111 connected to the top to perform a circular motion at one end of the lower connecting rod 111. Due to the second motor 24 provided at the bottom of the lower connecting member 115, it can drive the rotating member 21 to rotate around the upper connecting block 12 and the lower connecting member 115 while the motor 13 drives the active connecting rod 14 to rotate. The linkage rod 16 and the third lower connecting rod 114 are movably connected inside the connecting block 23 and the lower connecting block 25 protruding from the side of the rotating member 21, and can drive the entire robotic arm to rotate to expand the spraying area.
