[0048] like Fig.10The isolation device 3 includes a protrusion 46, a rack 47 and a protective plug plate 48. The protrusion 46 is fixedly installed on the bottom right side of the rack 47, and the rack 47 is fixedly installed on the bottom right side of the protective plug plate 48. When the protective plug plate 48 maintains a normal state inside the guide groove 35, it can be located above the threaded rod 14, so that dust can be prevented from accumulating on the surface of the threaded rod 14.

[0049] The supporting wing plates 12 are symmetrically fixedly installed on the rear ends of both sides of the hollow cavity 20, the driving motor 16 is fixedly installed on the left rear end of the workbench 24, the central cavity 45 is fixedly installed on the bottom rear end of the workbench 24, the protective plug plate 48 is slidably inserted in the guide groove 35, the conveying pipeline 4 is fixedly installed at the rear end center of the hollow cavity 20, the inner ring surface of the U-shaped push plate 10 is in contact with the top surfaces of both sides of the hollow cavity 20, the outer ring of the scraper 17 is in contact with the inner ring surface of the central cavity 45, the cleaning push plate 15 is equidistantly fixedly installed with scraper strips, and the scraper strips are slidably inserted in the gap inside the isolation filter 21, the bottom rear end of the workbench 24 is respectively provided with discharge grooves, and the cover plate 26 is vertically aligned with the discharge grooves, and the rear end of the extended front plate 27 is symmetrically fixedly installed with A button switch is provided, and the button switch is electrically connected to the electromagnetic valve 9. The interior of the special-shaped gas cylinder 31 is arranged in a hollow state, and a closed cavity is formed between the second piston rod 30, the special-shaped gas cylinder 31 and the first piston rod 22. The gear 28 is meshed with the rack 47. Both sides of the bottom of the protrusion 46 are inclined at 45°. The protrusion 46 is vertically aligned with the special-shaped gas cylinder 31.

The alignment key 38 on the second spring 33 is opposite to the alignment key 38 on the support block 37. The rear end of the connecting bracket 34 is connected to the front bottom of the U-shaped push plate 10. The inner front end of the workbench 24 is provided with a movable groove adapted to the isolation plate 25.

[0050] The working principle of the embodiment 1 is as follows: when in use, the external absorption device of the conveying pipe 4 can be connected, and then the household appliance to be disassembled can be placed on the top of the workbench 24, so that when the external absorption device is started, the dust generated when the household appliance is disassembled can be absorbed in time. After that, most of the flocculent dust can be isolated by the blocking of the isolation filter 21, so that the flocculent dust can be accumulated on the front end surface of the isolation filter 21. When the external absorption device is not started, the protective plug plate 48 can be pulled to the end away from the workbench 24, so that the rack 47 can be driven to pass through the gear 28, so that the gear 28 can drive the winding wheel 29 to rotate at the same time, so that the connecting rope 32 can pull the covering plate 26 and the isolation plate 25 to move to the front end. Through the setting of the wire wheel 36, it is convenient to The connecting rope 32 pulls the isolation plate 25 and the cover plate 26 to move toward the front end. When the cover plate 26 moves to the front end, it can be misaligned with the release groove inside the top of the workbench 24. At the same time, when the cover plate 26 moves to the front end to the limit position, it can drive the alignment key 38 at the bottom end of the second spring 33 to pass through the alignment key 38 at the top end of the support block 37, so that the alignment key 38 at the bottom end of the second spring 33 can be snapped at the front end of the alignment key 38 at the top end of the support block 37, thereby preventing the cover plate 26 from moving toward the rear end in advance. At the same time, when the cover plate 26 moves to the front end, the U-shaped push plate 10 can be driven to move toward the front end at the same time through the connecting bracket 34, so that the U-shaped push plate 10 can assist at the top ends of both sides of the isolation filter 21 to prevent the isolation filter 21 from being on the When the dust falls, it floats to the side end. Later, when the U-shaped push plate 10 moves to the front end to the extreme position, it can drive the electromagnetic valve 9 to contact the button switch at the rear end of the extended front plate 27. The electromagnetic valve 9 is electrically connected to the button switch, so that when the electromagnetic valve 9 contacts the button switch, the electromagnetic valve 9 can be started. In addition, when the U-shaped push plate 10 moves to the front end to the extreme position, it can drive the bottom end of the nozzle 8 to be vertically aligned with the front end surface of the isolation filter 21, so that the nozzle 8 can blow air to the front end surface of the isolation filter 21. After that, the driving motor 16 can be started to drive the threaded rod 14 to rotate. When the threaded rod 14 rotates, it can drive the cleaning push plate 15 to move inside the isolation filter 21, so that the cleaning push plate 15 can The flocculent dust in the gap of the net 21 is removed, so that the flocculent dust can fall along the surface of the isolation filter 21, and the flocculent dust can be guided by the blowing of the nozzle 8 until the flocculent dust enters the interior of the concentrated cavity 45, thereby completing the flocculent dust removal and unified collection work. At the same time, when the cleaning push plate 15 is moving, it can also drive the scraper 17 to move inside the concentrated cavity 45, so that the scraper 17 can squeeze and push the flocculent dust inside the concentrated cavity 45. When the scraper 17 moves along the interior of the concentrated cavity 45, it can drive the squeezing column 18 to contact the closing plate 43 in advance, so that when the scraper 17 has not moved to the extreme position, the squeezing column 18 can be driven to open the closing plate 43, so that when the scraper 17 moves to the extreme position,The flocculent dust inside the concentrated cavity 45 is pushed out to complete the flocculent dust removal work. When the interior of the isolation filter 21 is cleaned, the drive motor 16 can be started again to drive the threaded rod 14 to rotate in the opposite direction, so that the cleaning push plate 15 is reset. When the extrusion column 18 is out of contact with the closing plate 43, the elasticity of the fifth spring 44 drives the closing plate 43 to slowly reset until the closing plate 43 closes the interior of the concentrated cavity 45, and the closing plate 43 is slidably sleeved on the second guide rod 42, so that the sealing can be ensured. The plate 43 moves in a straight line to improve the docking accuracy of the concentrated cavity 45 and the closed plate 43. After that, when the cleaning push plate 15 is reset, the protective plug plate 48 can be slid into the inside of the guide groove 35 again, so that the protrusion 46 can be driven to contact the circular plate on the top of the second piston rod 30, thereby driving the second piston rod 30 to move downward. When the second piston rod 30 moves into the inside of the special-shaped air cylinder 31, the first piston rod 22 and the side sliding rod 40 can be driven to move downward at the same time, and the alignment key 38 is fixedly installed on the side sliding rod 40. When the side slide bar 40 moves downward, the alignment key 38 on the support block 37 can be misaligned with the alignment key 38 at the bottom of the second spring 33, so that the alignment key 38 at the bottom of the second spring 33 loses its restriction. After that, the elasticity of the fourth spring 41 drives the cover plate 26 to move toward the rear end until the cover plate 26 closes the release groove on the top of the workbench 24, and the isolation plate 25 closes the top of the workbench 24, which can maintain the integrity of the top surface of the workbench 24, making it convenient to place the waste household appliances on the workbench 24. 4, and at the same time, when the cover plate 26 is reset to the rear end, the U-shaped push plate 10 can be driven to move to the rear end at the same time, until the U-shaped push plate 10 is reset to the rear end and can be flush with the front end surface of the isolation filter 21, so that the U-shaped push plate 10 can be prevented from interfering with the waste household appliances on the workbench 24, and when the electromagnetic valve 9 is disconnected from the button switch at the rear end of the extension front plate 27, the electromagnetic valve 9 can be immediately powered off, so that the electromagnetic valve 9 can no longer deliver gas to the inside of the nozzle 8, thereby preventing energy waste.

[0051] Example 2

[0052] On the basis of Example 1, Fig.11 As shown, the extension bracket 19 also includes a rotating bracket 49, a limit pin 50 and a support base frame 51. The limit pin 50 is fixedly installed at the bottom front end of the extension bracket 19, the rotating bracket 49 is rotatably installed at the top front end of the extension bracket 19, and the support base frame 51 is slidably inserted into the inside of the limit pin 50 and the rotating bracket 49.

[0053] When implementing this embodiment, the extended front plate 27 is fixedly installed on the bottom front end of the rotating bracket 49. When the home appliance disassembly work needs to be carried out on the top of the workbench 24, the rotating bracket 49 can be flipped upward until the rotating bracket 49 can be misaligned with the top of the workbench 24, so as to prevent interference with the extended front plate 27 when disassembling the home appliance. Thereafter, when the surface of the isolation filter 21 needs to be cleaned, the rotating bracket 49 can be flipped toward the front end again until the rotating bracket 49 is rotated to fit with the top of the limit pin 50, so that the rotating bracket 49 can be supported to remain in a horizontal state to ensure the docking accuracy of the extended front plate 27 and the electromagnetic valve 9. Thereafter, the supporting base frame 51 can be inserted into the interior of the rotating bracket 49 and the limit pin 50 in turn, so that the rotating bracket 49 can be restricted and fixed inside the limit pin 50, thereby avoiding the rotating bracket 49 from shaking or shifting again during subsequent work.
