[0021] Embodiment 2: Based on the above embodiment, a residual adsorption mechanism 8 is provided inside the dust cylinder 6 .

[0022] Furthermore, the residual adsorption mechanism 8 includes a pull-out rod 802, a cavity 801 is provided inside the top dust barrel 6 at an equal distance corresponding to the pull-out rod 802, and the outer wall of the pull-out rod 802 fits and slides with the inner wall of the cavity 801, and a notch 804 is provided on the outer wall of the top dust barrel 6 at an equal distance corresponding to the pull-out rod 802, and a pull-out block 803 is fixedly connected to the end of the pull-out rod 802 facing the support plate 4, and the top of the pull-out block 803 extends to the outside of the top dust barrel 6 through the inner wall of the notch 804, and the top inner wall of the switch cabinet 1 is fixedly connected to the mounting rod 805 at an equal distance corresponding to the top dust barrel 6, and the bottom of the mounting rod 805 is fixedly connected to the pulling block 803 with a collar 806, and the inner wall of the collar 806 fits and slides with the outer wall of the top dust barrel 6; In this embodiment, the outer wall diameter of the dust tube 6 is slightly smaller than the inner wall diameter of the air outlet 3, so as to avoid the outer wall of the dust tube 6 being frequently rubbed against the inner wall of the air outlet 3 and being damaged, resulting in a reduction in service life; Then, under normal circumstances, a cavity 801 is opened at an equal distance from the inside of the top dust cylinder 6 corresponding to the pull-out rod 802, and the outer wall of the pull-out rod 802 slides in contact with the inner wall of the cavity 801, and a notch 804 is opened at an equal distance from the outer wall of the top dust cylinder 6 corresponding to the pull-out rod 802, and at the same time, a pull-out block 803 is fixedly connected to the end of the pull-out rod 802 toward the support plate 4, and the top of the pull-out block 803 extends through the inner wall of the notch 804 to the outside of the top dust cylinder 6, and the top inner wall of the switch cabinet 1 is fixedly connected to the top dust cylinder 6 at an equal distance. A mounting rod 805 is connected, and a collar 806 is fixedly connected to the bottom of the mounting rod 805 corresponding to the pull-out block 803, and the inner wall of the collar 806 fits and slides with the outer wall of the top dust barrel 6, so that when the top dust barrel 6 moves, the pull-out block 803 is synchronously driven to move. When one end of the top dust barrel 6 facing the air outlet 3 just touches the inner wall of the air outlet 3, the pull-out block 803 also conflicts with the surface of the collar 806. At this time, as the top dust barrel 6 continues to move, the pull-out block 803 moves backward relative to the top dust barrel 6. Under normal conditions, the cavity 801 is in a sealed state. When the pull-out block 803 drives the pull-out rod 802 to move relatively backward, the internal air pressure of the cavity 801 is reduced, and adsorption holes 807 are provided at equal distances through the outer wall of one end of the top dust tube 6 toward the air outlet 3, corresponding to the cavity 801, and the inner wall of the adsorption hole 807 is connected to the inner wall of the cavity 801, and the inner wall of the cavity 801 is fixedly connected with a fixing rod 808, and the outer wall of the fixing rod 808 is fitted with a spring 809, and the outer wall of the fixing rod 808 is fitted with a sliding connection. A connecting block 810 is provided, and a sealing plate 811 is fixedly connected to one side wall of the connecting block 810 corresponding to the adsorption hole 807, so that the sealing plate 811 in the adsorption hole 807 can be squeezed by the external atmospheric pressure, so that air enters the cavity 801 from the adsorption hole 807, and then the adsorption hole 807 on the side wall of the top dust cylinder 6 can be used to adsorb the residual dust on the inner wall of the air outlet 3, and the top dust cylinder 6 can rotate itself to fully adsorb the residual dust in the air outlet 3, thereby ensuring the dust cleaning effect of the air outlet 3; When the dust collecting plate 801 is fully pushed in, the pull rod 802 stops moving, and the spring 809 is set so that the spring 809 can push the connecting block 810 to reset, so that the blocking plate 811 can block the adsorption hole 807 again, so as to prevent the residual dust collected in the cavity 801 from being discharged from the adsorption hole 807. Then, the dust collecting plate 6 returns to its original position, and the spring 817 is fixedly connected to one side wall of the support plate 4 through the pull block 803, and the other end of the spring 817 is fixedly connected to the inner wall of the cavity 801, so that the pull block 803 can be driven by the spring 817 to reset and push the air inside the cavity 801. At this time, the blocking plate 811 will be limited by the installation position and cannot move. At this time, a discharge hole 812 is formed through the inner wall of one end of the top dust tube 6 toward the air outlet 3 at an equal distance from the cavity 801, and the inner wall of the discharge hole 812 is connected to the inner wall of the cavity 801, and the other end of the fixing rod 808 is fixedly connected to the support plate 2 813, and the outer wall of the fixing rod 808 is fitted with a spring 3 814, and the outer wall of the fixing rod 808 is fitted with a connecting block 2 815, and one side wall of the connecting block 2 815 is fixedly connected to the discharge hole 812. A second sealing plate 816 is connected, so that the air inside the cavity 801 squeezes and pushes the second sealing plate 816 open, so that the dust collected in the cavity 801 enters the inner wall of the dust-top cylinder 6 through the discharge hole 812. At this time, the collecting cylinder 10 is connected to the inner wall of the ejection cylinder 701 through the thread, and the inner wall of the ejection cylinder 701 is connected to the inner wall of the dust-top cylinder 6, so that the discharged residual dust is sent to the collecting cylinder 10, and the collecting cylinder 10 can be rotated out regularly for cleaning, which is simple and convenient; Then, when the dust cylinder 6 is returned to its original position, the spring 3 814 drives the connecting block 2 815 to be reset, and drives the blocking plate 2 816 to block the discharge hole 812 again, thus completing the adsorption cleaning step; By doing as above, during the operation of the equipment, the ring 806 can be used to restrict the movement of the pull-out block 803 during the ejection process, so that during the ejection process, the front end of the dust tube 6 can use the adsorption hole 807 on the side wall to adsorb the residual dust on the inner wall of the air outlet 3, and cooperate with the rotation of the dust tube 6 itself, so as to fully adsorb the residual dust in the air outlet 3, thereby ensuring the dust cleaning effect of the air outlet 3, and further helping to reduce the electromagnetic interference risk of the present equipment.

[0023] Working principle: During the operation of the device, the outside air is first drawn into the switch cabinet 1 through the fan 2 on one side and discharged through the multiple air outlets 3 on the other side. When a certain set time is reached, the threaded rod 707 can be driven to rotate by the driving motor 706. At the same time, under the restriction of the trigger rod 709 and the limit slot 9, the threaded rod 707 can drive the trigger rod 709 to move through the connecting ring 708; During the movement, it will first contact and drive one of the levers 705, so that the lever 705 can drive the ejector tube 701 to rotate through the support plate 1 704. At this time, under the cooperation of the spiral groove 702 and the ball 703, the ejector tube 701 can move toward the direction of the air outlet 3 during the rotation, so that the multiple dust ejector tubes 6 can be quickly and orderly pushed into the multiple air outlets 3 in turn, and the accumulated dust adsorbed by static electricity is ejected and cleaned, without affecting the normal circulation of the other air outlets 3, without stopping the equipment, and avoiding the reduction of the air volume in the air outlet 3; Then, when the top dust tube 6 moves, the pull-out block 803 is synchronously driven to move. When one end of the top dust tube 6 facing the air outlet 3 just touches the inner wall of the air outlet 3, the pull-out block 803 also contacts the surface of the collar 806. At this time, as the top dust tube 6 continues to move, the pull-out block 803 moves backward relative to the top dust tube 6. Then, when the pull block 803 drives the pull rod 802 to move relatively backward, the internal air pressure of the cavity 801 is reduced. At this time, the sealing plate 811 in the adsorption hole 807 is squeezed by the external atmospheric pressure, so that air enters the cavity 801 from the adsorption hole 807, and then the adsorption hole 807 on the side wall of the top dust tube 6 can be used to adsorb the residual dust on the inner wall of the air outlet 3, and the top dust tube 6 can rotate itself to fully adsorb the residual dust in the air outlet 3; When it is fully pushed in, the pull rod 802 stops moving, and the sealing plate 1 811 is used to re-seal the adsorption hole 807 through the spring 2 809 to prevent the residual dust collected in the cavity 801 from being discharged from the adsorption hole 807. Then, the top dust barrel 6 returns to its original position to push the air inside the cavity 801. At this time, the sealing plate 1 811 will be unable to move due to the installation position, so that the air inside the cavity 801 will squeeze and push the sealing plate 2 816 open, so that the dust collected in the cavity 801 enters the inner wall of the top dust barrel 6 through the discharge hole 812 and is sent into the collecting barrel 10. Then, when the top dust barrel 6 returns to its original position, the spring 3 814 will drive the sealing plate 2 816 to re-seal the discharge hole 812, completing the adsorption and cleaning step.
