The telescopic air bag 12 is made of elastic rubber materials, and can effectively buffer the vibration of the second driving rod 11 and the filtering device 2. It should be noted that the filtering device 2 generates electromagnetic vibrations in multiple directions when operating, wherein the vibrations in the up-down direction will make the first driving rod 5 and the second driving rod 11 push the rubber part 702 and the flexible airbag 12 up and down, so that the internal volumes of the air inlet pipe 7 and the flexible airbag 12 can be changed in an increasing or decreasing manner, for the air inlet pipe 7, negative pressure can be generated when the internal volume is increased to draw air into the air inlet pipe, and when the internal volume is decreased, the internal air is squeezed into the dehumidifying box 6; for the telescopic air bag 12, when the air is increased, the air in the strip-shaped groove 18 is sucked into the telescopic air bag 12 to move the piston 19 upwards, and when the air is decreased, the air is squeezed into the strip-shaped groove 18 to move the piston 19 downwards.

In the invention, when the filtering device 2 generates electromagnetic vibration during working, the first driving rod 5 and the second driving rod 11 on two sides are driven to synchronously vibrate at the same time. When the first driving rod 5 continuously vibrates, the rubber part 702 of the air inlet pipe 7 is pulled up and down and continuously deforms in a convex-concave manner, so that the integral volume inside the air inlet pipe 7 is periodically increased and reduced, thus air in the shell 1 is continuously sucked and then discharged into the dehumidifying box 6 under the current limiting action of the check valves at the two ends, when the first driving rod 5 vibrates up and down along with the air, the magnetic part on the side wall of the first driving rod continuously enters and exits the spiral coil 8, so that the magnetic flux in the spiral coil 8 is changed and generates current, thus the vibration kinetic energy of the filter device 2 can be converted into electric energy and the semiconductor refrigerating sheet 17 is electrified, the temperature of the semiconductor refrigerating sheet 17 is reduced after the electrification, when the air discharged from the air inlet pipe 7 enters the dehumidifying box 6, the air continuously passes through the semiconductor refrigerating sheet 17 through the vent 21, and water vapor in high-temperature air is condensed when encountering the cold semiconductor refrigerating sheet 17, thus, water vapor can be actively condensed into liquid on the surface of the semiconductor refrigerating sheet 17 and can drop into the flow guide pipe under the action of gravity.

And second actuating lever 11 is when vibration from top to bottom thereupon, but the flexible gasbag 12 of periodic extrusion for the air in the flexible gasbag 12 makes a round trip to flow in bar groove 18 and flexible gasbag 12 inside, so can promote piston 19 reciprocating motion from top to bottom, promote simultaneously through the connecting rod and scrape ring 20 synchronous motion, thereby the drop of water that will condense on semiconductor refrigeration piece 17 scrapes off, improve dehumidification drying efficiency, and elastic flexible gasbag 12 also can cushion second actuating lever 11 and the vibration of filter equipment 2, can reduce its vibration range. The condensed water flowing into the flow guide tube 16 will continue to flow into the serpentine condensation groove 14 on the heat conducting plate 4 under the action of gravity, and the condensed water can absorb the heat of the filtering device 2 and cool the filtering device while flowing in the serpentine condensation groove 14, and is finally discharged by the water discharge tube 15.

In conclusion, the device can collect and utilize the kinetic energy of the electromagnetic vibration generated when the filtering device 2 works so as to drive the cooling device, the expansion and contraction device and the driving mechanism to operate, can greatly consume the electromagnetic vibration kinetic energy, on one hand, can reduce the vibration amplitude and further reduce the intensity of the generated noise, on the other hand, the air in the shell 1 can continuously flow through the cooling device through the expansion device, water vapor in the air is actively condensed and discharged through the flow guide pipe, thus effectively improving the dryness of the air in the shell 1, preventing the condensation when the work is stopped, in addition, the condensed water is discharged into the snake-shaped condensation groove 14 to cool the filtering device 2, so that the ambient temperature of the power filter can be reduced while the filtering device 2 is protected, the water vapor containing amount in the air is reduced, and the condensation condition can be further avoided.
