Referring to fig. 1 and fig. 2, the present embodiment relates to an air intake mechanism of a sweeper, which includes an air duct pipeline 1, a suction cup 2 and a centrifugal fan 3, wherein the suction cup 2 is communicated with the air duct pipeline 1, the suction cup 2 is provided with a baffle plate 21, the baffle plate 21 is arranged opposite to an inlet of the air duct pipeline 1, and the baffle plate 21 is provided with a slot 211; the centrifugal fan 3 is used for providing suction for the sucker 2. The centrifugal fan is used for providing suction for the sucker through the slotted hole formed in the baffle; at the moment, local vortex is generated at the inlet of the air duct pipeline, so that the tripping speed of the particles is reduced, and the solid particles are favorably absorbed. Meanwhile, the whole flow area is increased due to the arrangement of the slotted holes, the wind resistance of the system is obviously reduced, the energy consumption of the auxiliary engine of the sweeper is reduced, and the purposes of energy conservation and emission reduction are achieved.

The settling chamber is arranged at the outlet of the air duct pipeline, the solid in the gas-solid mixture discharged from the air duct pipeline naturally falls into the settling chamber through gravity, and the gas is further filtered through the arranged filter screen, so that the separation of the gas and the solid is realized.
Preferably, the air inlet mechanism of the sweeper further comprises a solid baffle 5, the solid baffle 5 is located on the inner side surface of the top of the sweeper body 4, and the solid baffle 5 is arranged opposite to the outlet of the air duct pipeline 1. The solid baffle can be arranged at a certain angle with the inner side surface of the top of the sweeper box body, so that gas discharged from the air duct pipeline can better enter the filter screen after colliding with the solid baffle. The gas flow direction is changed by the solid baffle plate, so that the gas is better filtered.
Preferably, the outlet of the air duct line 1 is directed towards the top of the settling chamber 41. The outlet of the air duct pipeline faces the top of the settling chamber, when the gas-solid mixture is discharged from the air duct pipeline, huge impact force can be generated, the gas-solid mixture can impact the top of the settling chamber, and the solid can drop to the bottom of the settling chamber due to the action of gravity, so that the solid is deposited.

The entrance of the air channel pipeline is oppositely provided with the vortex generator, when the sucking disc sucks the gas-solid mixture, the vortex generator can generate local vortex at the entrance of the air channel, the wind resistance of the air channel is reduced, and the suction of the gas-solid mixture is facilitated. The vortex generator further reduces the wind resistance of the air channel on the basis that the sucker sucks the gas-solid mixture, so that more gas-solid mixture is sucked.
Referring to fig. 3, the slot 211 is a rectangular parallelepiped. Because the cuboid hole is of a square structure, the cuboid hole is more convenient to manufacture on the baffle.
Preferably, the number of the slots 211 is more than 2, and the slots 211 are uniformly distributed on the baffle 21. The quantity of slotted hole directly influences the circulation of air, and the slotted hole quantity is more, the increase of circulation of air area, and the windage of system obviously reduces, has reduced the energy consumption of motor sweeper auxiliary engine. In the embodiment, the number of the slotted holes is 11, and the slotted holes are uniformly distributed on the baffle plate, so that on one hand, the number of the slotted holes is enough, the air circulation area is large enough, and the energy consumption of an engine of the sweeper can be effectively reduced; on the other hand, the number of the slotted holes is 11, so that the processing is more convenient.
Preferably, the distance (b) between two adjacent slotted holes is 25mm-40 mm. The distance between two adjacent slots is not too close, thereby affecting the manufacture of the slots. The distance (b) between two adjacent slotted holes is 25mm-40mm, so that the slotted holes can be more conveniently manufactured on the baffle plate.
Preferably, the distance (a) from the slot 211 to the side edge of the baffle 21 is 30mm to 55 mm. When cleaning rubbish, the arrangement of slotted hole directly influences the effect of circulation of air. The distance (a) from the slotted hole to the side edge of the baffle is 30-55 mm, so that the effect of air circulation can be better achieved, and the consumption of an engine of the sweeper is reduced.
In this embodiment, the inventor also provides a sweeper, including sweeper air inlet mechanism and vehicle chassis, sweeper air inlet mechanism sets up on the vehicle chassis. When the sweeper cleans garbage, air inside the sweeper is extracted and exhausted out of the sweeper by the air inlet mechanism of the sweeper arranged on the chassis of the sweeper, so that the air pressure inside and outside the sweeper is unbalanced. In order to keep the balance of the internal and external air pressure, a sucking disc of the air inlet mechanism of the sweeper operates to suck the garbage on the ground into the sweeper, so that the garbage is cleaned.
Different from the prior art, the technical scheme is that the baffle is provided with the slotted hole, and the centrifugal fan is used for providing suction for the sucker; at the moment, local vortex is generated at the inlet of the air duct pipeline, so that the tripping speed of the particles is reduced, and the solid particles are favorably absorbed. Meanwhile, the whole flow area is increased due to the arrangement of the slotted holes, the wind resistance of the system is obviously reduced, the energy consumption of the auxiliary engine of the sweeper is reduced, and the purposes of energy conservation and emission reduction are achieved.
