by arranging the side plates 4 to form an air inlet channel which is vertically arranged in the shell 1, so that external air moves upwards along the vertical direction after entering from the air inlet 13, and by matching with the situation that the speed is relatively low when the electric push rod 2 drives the moving plate 23 upwards, dust in the external air entering the air inlet channel can stay in the air inlet channel or subside downwards in the air inlet channel under the action of gravity, the quantity of dust in the external air reaching the filter screen 5 in the air inlet channel is reduced, the filter screen 5 is beneficial to filtering the external air and intercepting the external dust from entering, meanwhile, because the air in the shell 1 is unidirectionally discharged outwards from the air outlet 12, the mesh diameter of the filter plate 121 arranged at the air outlet 12 is relatively large, insects or small animals can be intercepted, so that the dust entering the shell 1 is easy to discharge from the air outlet 12, and because the foot pad 11 symmetrically arranged at the bottom of the shell 1 and the air outlet 12 are positioned between the foot pad 11, the air discharged from the air outlet 12 and the dust possibly existing in the air can be guided by the foot pad 11, and the air is prevented from being discharged from the air inlet 13 and the air from being far away from the air inlet 13;
when external air enters the movable cavity 22, the swinging plate 41 at the ventilation gap of the air inlet channel swings, so that the connecting rope 52 is pulled to drive the cleaning plate 51 to move upwards, the cleaning plate 51 and the filter screen 5 are separated from each other, after that, when the air in the movable cavity 22 is filled into the shell 1, the ventilation gap of the air inlet channel is closed, the swinging plate 41 returns to the original position, so that the cleaning plate 51 pulled by the connecting rope 52 falls downwards under the action of gravity, the cleaning plate 51 and the filter screen 5 are finally contacted with each other, the cleaning plate 51 is abutted against and impacted against the filter screen 5, the filter screen 5 is impacted and vibrated so as to remove dust attached to the filter screen 5, the dust falls off the signal source equipment from the air inlet channel, the condition that the signal source equipment is blocked due to excessive dust attached to the filter screen 5 is avoided, the heat dissipation effect of the signal source equipment is influenced, meanwhile, the impact and vibration are carried out on the filter screen 5 when air flow in a pulse form is generated each time, the attached dust and dust can be removed, the dust can also effectively and the dust attached on the filter screen 5 can be effectively removed, the dust attached on the filter screen can pass through the filter screen 5 in a small-diameter vibration signal and enter the ventilation equipment;
through setting up inside cavity and inflated cavity on cleaning plate 51 for when cleaning plate 51 falls and touches filter screen 5, utilize elastic layer 53 to cushion, avoid cleaning plate 51 to the too big impact of filter screen 5, cause filter screen 5 to damage, simultaneously, cleaning plate 51 contacts with filter screen 5 through elastic layer 53, avoid cleaning plate 51's edge or edges and corners to produce the damage to filter screen 5, influence the normal use of signal source equipment;
through the blowing holes formed in the elastic layer 53, when the cleaning plate 51 falls down and impacts the filter screen 5, the compressed air in the cavity is sprayed out to further flush the filter screen 5, so that the effect of removing dust attached to the filter screen 5 is improved, the condition that the filter screen 5 is blocked after long-term use is avoided, and meanwhile, the outlets of the blowing holes are pointed to the filter screen 5 and the outlet directions of the blowing holes are different, so that the blown air flow covers the surface of the filter screen 5 as much as possible, and the effect of cleaning the dust attached to the filter screen 5 is improved;
the mutually staggered metal sheets 43 are arranged on the inner wall of the air inlet channel, so that the path of outside air passing through the air inlet channel is increased, the flow speed of the outside air in the air inlet channel is further slowed down by utilizing the blocking of the metal sheets 43, dust is beneficial to hovering or settling in the air inlet channel under the action of gravity, and finally, when air flow is filled into the shell 1, the dust is discharged out of the shell 1, meanwhile, the metal sheets 43 are obliquely arranged downwards, when the flow resistance of the outside air is increased, and the flow speed of the air flow is slowed down, dust and other impurities entering into the air inlet channel can fall off the metal sheets 43 easily, and the dust and other impurities leave the interior of the shell 1;
because the metal sheet 43 is connected in the air inlet channel through the metal wire 431 with elasticity, when outside air passes through the air inlet channel, the metal sheet 43 can vibrate, and when the outside air passing through is blocked, the metal sheet 43 can be cleaned to a certain extent, so that impurities such as dust are prevented from adhering to the metal sheet 43, and the subsequent use of the metal sheet 43 is influenced.
