The top surface of the spray head 74 is symmetrically provided with a pair of impact frames 81 based on the center, and one end of the impact frame 81 away from the spray head 74 is close to the annular mounting plate 21 and a gap is formed between the impact frame and the annular mounting plate 21; when the spray head 74 is intermittently impacted, the end part of the impact frame 81 is impacted against the annular mounting plate 21 in a clearance manner, so that the annular mounting plate 21 drives the flow dividing cylinder 23 to oscillate, the flow dividing cylinder 23 drives the inner partition plate 24 and the flow dividing cone 25 to oscillate synchronously, and the falling of the oil smoke particles attached to the surface is accelerated.
When the installation device works, the installation shell 1 is installed on a wall body, and then the receiving cylinder 2 inserted into the installation shell 1 is fixed through the second connecting piece; when strong external wind rushes into the installation shell 1, air flow needs to pass through the windproof valve assembly, and when specific air flow enters the inside of the split cylinders 23, the air flow needs to pass through the space between the partition plates 24, then the split cones 25 between the partition plates 24 divide the air flow into two parts, one part enters the grooves, the grooves receive the air flow and control the air flow to the original flow direction of the air flow to offset, so that the whole air flow is slowed down, the air flow flowing backwards into the room is greatly slowed down by the cooperation of the split cylinders 23, the air flow entering the room is difficult to cause the turbulence of the indoor air flow, and the influence on people or objects in the room is avoided; the structure inside the split flow cylinder 23 needs to be cleaned after a period of use, specifically, the nut 32 is twisted during cleaning, then the nut 32 is removed from the fixing screw 3, so that the connection between the fixing plate 31 and the fixing screw 3 is released, then the receiving cylinder 2 is extracted from the installation shell 1, and then the split flow cylinder 23 inside the receiving cylinder 2 and the structure inside the split flow cylinder 23 are cleaned; during cleaning, the carrying cylinder 2 is dismounted, then the air pump 42 is started, the air pump 42 inflates the inflation air bags 41, the pair of inflation air bags 41 are inflated to mutually support and press, finally the carrying cylinder 2 is separated, then the carrying cylinder 2 is erected, cleaning liquid is injected into the carrying cylinder 2, and the cleaning liquid is separated by the inflation air bags 41, so that the cleaning liquid is prevented from contacting with the ventilation assembly 11, and the driving motor of the ventilation assembly 11 is prevented from being wetted; the cleaning liquid can soak the diversion cylinder 23 in the receiving cylinder 2, and the diversion cylinder 23 does not need to be detached from the receiving cylinder 2 during soaking, so that the cleaning process is further simplified; in the cleaning start cylinder 51, the cylinder 51 drives the blocking block 52 to drive the separating through hole, and the cleaning solution injected into the receiving cylinder 2 is sprayed out through the through hole, so that the cleaning solution passing through the distributing cylinder 23 is in a flowing state, the flushing of the distributing cylinder 23 is realized, and the cleaning effect is improved; and the inflation bladder 41 isolates the ventilation assembly 11 while continuing to flush.
When the cleaning solution is sprayed out through the through hole, the water flow impacts the baffle plate 54, the baffle plate 54 drives the bearing shaft 53 to rotate, the rotating bearing shaft 53 throws the oscillating block 55 out of the inside of the inserting groove 56 through centrifugal force, and the oscillating block 55 is limited by the tension spring, so that the inner wall of the bearing cylinder 2 is impacted in a clearance way when rotating, the bearing cylinder 2 vibrates, the bearing cylinder 2 transmits the vibration to the distribution cylinder 23 through the annular mounting plate 21, the partition plate 24 in the distribution cylinder 23 vibrates synchronously with the distribution cone 25, and sundries attached to the surfaces of the partition plate 24 and the distribution cone 25 are accelerated to fall off; when the ventilation assembly 11 works, indoor air is extracted, when the room is a kitchen, a large amount of oil smoke particles are carried in the extracted air, the oil smoke particles can be attached to the structure inside the diversion cylinder 23, so that the diversion cylinder 23 is gradually blocked, when the blockage is to a certain extent, in order to avoid affecting normal use, shutdown cleaning is needed, particularly when the diversion cylinder 23 is gradually blocked, the diversion cylinder 23 is gradually increased by airflow impact force, the diversion cylinder 23 is arranged at the end part of the annular mounting plate 21, the annular mounting plate 21 applies the airflow impact force to the surface of the linkage plate 22, the linkage plate 22 drives the sliding block 61 to move in the sliding groove 6, the supporting spring 62 is extruded, the linkage plate 22 synchronously moves to drive the pressing block at the end part of the linkage frame 63 to be close to the touch switch of the alarm 64, and when the touch switch of the alarm 64 is extruded, the alarm 64 sends an early warning signal to the outside, so that workers are reminded of cleaning treatment; when the touch switch of the alarm 64 is pressed, the touch switch controls the liquid pump 72 to start, the liquid pump 72 pumps the degreasing agent in the storage tank 7 into the guide pipe 73, the degreasing agent is sprayed into the receiving cylinder 2 through the spray head 74, the degreasing agent enters the flow distribution cylinder 23 along with the air flow, oil smoke particles attached to the inner structural surface of the flow distribution cylinder 23 are dissolved, and then fall off along with the air flow, so that the flow distribution cylinder 23 is dredged, and preliminary dredging and cleaning are carried out before cleaning by workers; when the spray head 74 sprays the degreasing agent, the telescopic rod 8 is started, the output end of the telescopic rod 8 intermittently impacts the spray head 74, so that the spray head 74 drives the guide pipe 73 to bend, the guide pipe 73 is prepared by elastic materials, bending can be generated when the pressure is released, and the bending automatically recovers when the pressure is released, so that the spray nozzle of the spray head 74 continuously adjusts the angle, the spraying angle of the degreasing agent is increased, and the degreasing agent entering the receiving barrel 2 is distributed more uniformly; when the spray head 74 is intermittently impacted, the end part of the impact frame 81 is intermittently impacted against the annular mounting plate 21, so that the annular mounting plate 21 drives the flow dividing cylinder 23 to oscillate, the flow dividing cylinder 23 drives the inner partition plate 24 to oscillate synchronously with the flow dividing cone 25, and the falling of the oil smoke particles attached to the surface is accelerated.
