It should be noted that, when the cam 27 rotates along with the third gear 25, the protruding end of the cam 27 will continuously press the pressing plate 32 on the right side, so that the air plug 30 can be pushed to move right by the connecting rod 31, and air on the right side of the air plug 30 is input into each bellows 23 through the exhaust pipe 33 and each air duct 34, and finally the bellows 23 is stretched, so that the scraping ring 35 can be pushed to move outwards, and when the cam 27 is separated, the spring 29 pushes the air plug 30 to move left and reset, and simultaneously, the air in the bellows 23 is drawn back, and the scraping ring 35 is pulled back.
In the present application, as shown in fig. 1 and 6, since the top and bottom of the inside of the housing 1 are blocked, when the air is introduced into the air conditioning system, air enters through the grill holes 16 on the front and rear sides of the housing 1, is filtered through the filter cloth 11, enters the middle of the filter cloth 11, and flows into the air conditioning system through the air supply passage 9 below.
In this process, the driving motor 4 will drive the first gear 5 to rotate, and make the second gear 6 and the third gear 25 meshed with the first gear 5 all rotate, and the first gear 5 can drive the driving roller 2 to rotate when rotating, so that the filter cloth 11 on the outer side of the filter cloth can circularly rotate. The areas of the filter cloth 11 are continuously rotated to the right, so that the filter cloth 11 can be uniformly consumed and used, and the areas of the filter cloth 11 are conveniently transported to the right side of the outer cylinder 10 to be conveniently cleaned.
When the third gear 25 rotates, the centrifugal fan in the air drum 13 is driven to rotate circularly, the centrifugal fan runs immediately, clean air entering the air supply channel 9 can be continuously pumped away and blown into the inner drum 21 from the air outlet pipe 15, the outer drum 10 is driven to rotate synchronously when the third gear 25 rotates, and the inner drum 21 is fixed, and the blowing holes 22 on the circumferential side wall of the outer drum 10 are continuously communicated with the through holes 8 in the continuous rotation process of the outer drum 10, so that air flow blown into the inner drum 21 is only blown outwards from the blowing holes 22 on the right side, and when the through holes 8 are in a fitting state with the inner wall of the outer drum 10, the blowing holes 22 stop blowing air flow. The blowing holes 22 on the far right side of the outer cylinder 10 intermittently blow out the air flow, so that a matrix of air flows on the filter cloth 11 to apply an impact force to the filter cloth 11, and the dust on the filter cloth 11 is caused to fall.
In addition, when the wind shield 12 on the outer cylinder 10 is not opposite to the through hole 8, the small magnetic sheet 24 can absorb the wind shield 12 on the side wall of the outer cylinder 10 by means of magnetic force, when the wind shield 12 is opposite to the through hole 8, the wind shield 12 can be blown open when the air current is blown out from the blowing hole 22, as shown in fig. 4 and 5, the wind shield 12 is turned upwards after being blown open, and the filter cloth 11 is driven once, so that the filter cloth 11 can shake, and dust on the filter cloth 11 is further promoted to fall off.
Further, when the third gear 25 rotates, referring to fig. 7 and 6, the connecting shaft below the third gear also rotates along with the third gear to drive the cam 27 to rotate together, and the cam 27 periodically touches the right pressing plate 32 and pushes the air plug 30 to move right through the connecting rod 31 in the rotating process, so that the air in the air injection groove 28 can be input into each expansion bellows 23 from the exhaust pipe 33 and each air duct 34, and the air pressure in the expansion bellows 23 is increased, so that the expansion bellows 23 is stretched, and the pushing scraping ring 35 can be moved inside and outside the grid hole 16; when the cam 27 leaves the pressing plate 32, the spring 29 can push the air plug 30 to move left for resetting, and the air in each telescopic corrugated pipe 23 is pumped back into the air injection groove 28 along the air guide pipe 34 and the air exhaust pipe 33, at the moment, the telescopic corrugated pipe 23 is contracted, so that the scraping ring 35 is reset back and forth, and therefore, in the circulating rotation process of the third gear 25, the scraping ring 35 also moves back and forth in the grating holes 16, and debris such as chips entering the grating holes 16 can be pushed out continuously, and the grating holes 16 are prevented from being blocked.
The foregoing is only a preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art, who is within the scope of the present application, should make equivalent substitutions or modifications according to the technical scheme of the present application and the inventive concept thereof, and should be covered by the scope of the present application.
