[0026] During use, the motor 51 is started to drive the turntable 52 to rotate. The turntable 52 drives the slide rod 59 to slide within the first semi-circular chute 521, the second semi-circular chute 522, and the connecting groove 524. When the slide rod 59 slides within the second semi-circular chute 522, it drives the left end of the first adjusting rod 541 to move forward, thereby driving the right end to move backward. Further, it drives the linkage rod 561 to move backward through the fixed rod 543. The linkage rod 561 drives the second adjusting rod 551 to move backward through the latch 562, driving the toothed plate 553 to engage with the driving gear 57. At the same time, the turntable 52 rotates, driving the support rod 554 to rotate. While the support rod 554 rotates, it drives the second adjusting rod 551 to move to the right. The second adjusting rod 551 moves to the right, driving the driving gear 57 to rotate through the toothed plate 553. Thus, it drives the workbench 4 to rotate through the rotating rod 53, thereby driving the accessory to rotate, and spraying paint on different directions of the accessory. When the slide rod 59 enters the first semi-circular chute 521 from the connecting groove 524 out of the second semi-circular chute 522, it drives the left end of the first adjusting rod 541 to move backward, thereby driving the right end to move forward.

At the same time, it drives the movable plate 583 to move forward through the fixed rod 543, driving the locking teeth 587 to engage into the driving gear 57. During the process of the motor 51 driving the turntable 52 to rotate and the slide rod 59 sliding within the first semi-circular chute 521 and driving the support rod 554 to rotate, the driving gear 57 is not driven. By repeating the above operations, the different surfaces of the accessory can be sprayed with paint, making the paint on the surface of the accessory uniform and complete, eliminating the need for manual spraying, automatically adjusting the spraying surface, and improving work efficiency.

[0027] Further, the intermittent rotation device 5 further includes a worm gear 510, a worm 511 and two fixing plates 513. The worm gear 510 is rotatably installed in the middle of the upper end of the turntable 52. The fixing plates 513 are fixedly installed on the top wall of the equipment cavity 3.

The second driving rod 77 drives the second reciprocating screw 71 to rotate, so as to drive the second driving block 73 to reciprocate up and down, so as to drive the installation block 74 to reciprocate up and down. The heating wires 75 in the installation groove 741 in the installation block 74 work to generate heat and heat the air. The fans 76 blow the hot air onto the surface of the fittings to dry the painted surface. At the same time, the filter screen 79 provided makes the wind more gentle after passing through the filter screen 79 and will not impact the paint. At the same time, the filter screen 79 also plays a filtering role to prevent dust from being blown onto the painted surface and affecting the painting effect.

[0030] The working principle of the present invention is as follows: When in use, place the home appliance accessory on the workbench 4, start the motor 51, the start of the motor 51 drives the turntable 52 to rotate, the turntable 52 drives the slide rod 59 to slide in the first semi-circular chute 521, the second semi-circular chute 522 and the connecting groove 524. When the slide rod 59 slides in the second semi-circular chute 522, it drives the left end of the first adjusting rod 541 to move forward, thereby driving the right end to move backward, and further driving the linkage rod 561 to move backward through the fixed rod 543. The linkage rod 561 drives the second adjusting rod 551 to move backward through the block 562, driving the toothed plate 553 to mesh with the driving gear 57. At the same time, the turntable 52 rotates, driving the support rod 554 to rotate. While the support rod 554 rotates, it drives the second adjusting rod 551 to move to the right. The second adjusting rod drives the driving gear 57 to rotate through the toothed plate 553, thereby driving the workbench 4 to rotate through the rotating rod 53, driving the accessory to rotate, so as to facilitate the painting device 6 to paint different directions of the accessory. When the slide rod 59 enters the first semi-circular chute 521 from the connecting groove 524 of the second semi-circular chute 522, it drives the left end of the first adjusting rod 541 to move backward, thereby driving the right end to move forward, and further driving the linkage rod 561 to move forward through the fixed rod 543. The linkage rod 561 drives the second adjusting rod 551 to move forward through the block 562, driving the toothed plate 553 to disengage from the driving gear 57. At the same time, it drives the movable plate 583 to move forward through the fixed rod 543, driving the engaging teeth 587 to engage into the driving gear 57, restricting the rotation of the driving gear 57. During the process of the motor 51 driving the turntable 52 to rotate and the slide rod 59 sliding in the first semi-circular chute 521, driving the support rod 554 to rotate, the driving gear 57 will not be driven. By repeating the above operations, the accessory can be driven to perform intermittent movement. During the process when the accessory stops moving, the solenoid valve 63 transports the paint in the paint tank 61 into the liquid outlet pipe 62, and then transports it to the spray head 68 through the hose 64 and sprays it out through the spray head 68 to spray the surface of the accessory. The toothed ring 523 drives the driven gear 610 to rotate, the driven gear 610 drives the first driving rod 69 to rotate, the first driving rod 69 drives the first reciprocating screw rod 65 to rotate, driving the first driving block 67 to move up and down, thereby driving the spray head 68 to move up and down, reciprocatingly spraying the accessory from top to bottom, and the spraying effect is good. Then the intermittent rotation device 5 drives the painted surface of the accessory to rotate to the rear, drives the worm 511 to rotate through the worm gear 510, the worm 511 drives the driving bevel gear 512 to rotate, driving the driven bevel gear 78 to rotate, thereby driving the second driving rod 77 to rotate, the second driving rod 77 drives the second reciprocating screw rod 71 to rotate, thereby driving the second driving block 73 to reciprocate up and down, thereby driving the mounting block 74 to reciprocate up and down. The heating wire 75 in the mounting groove 741 in the mounting block 74 works to generate heat, heating the air, and the fan 76 blows the hot air towards the surface of the accessory to dry the painted surface. At the same time, the provided filter net 79 makes the wind more gentle after passing through the filter net 79 and will not impact the paint.Meanwhile, the filter screen 79 also plays a role in filtering to prevent dust from blowing onto the painted surface and affecting the painting effect.
