Please refer to FIG. 1 and FIG. 2 , the present embodiment relates to an air intake mechanism for a sweeper, including an air duct pipe 1, a suction cup 2 and a centrifugal fan 3. The suction cup 2 is communicated with the air duct pipe 1, so The suction cup 2 is provided with a baffle 21, the baffle 21 is arranged opposite to the inlet of the air duct pipe 1, and the baffle 21 is provided with a slot 211; the centrifugal fan 3 is used for the The suction cup 2 provides suction. By arranging a slot hole on the baffle, the centrifugal fan is used to provide suction for the suction cup; at this time, the local vortex generated at the entrance of the air duct pipeline reduces the take-off speed of the particles, which is beneficial to Solid particulate matter is absorbed. At the same time, due to the increase of the overall flow area due to the slotted holes, the wind resistance of the system is significantly reduced, the energy consumption of the auxiliary engine of the sweeper is reduced, and the purpose of energy saving and emission reduction is achieved.

Preferably, the air intake mechanism of the sweeper further includes a sweeper box 4 , and the sweeper box 4 includes a filter screen 42 and a settling chamber 41 , and the settling chamber 41 is arranged relative to the outlet of the air duct pipeline 1 . , the filter screen 42 is disposed opposite to the outlet of the settling chamber 41 , and the filter screen 42 is used to filter the gas in the settling chamber 41 . A settling chamber is set at the outlet of the air duct pipeline, and the solids in the gas-solid mixture discharged from the air duct pipeline are naturally dropped into the settling chamber by gravity, and the gas is further filtered through the set filter screen, so as to realize the gas and solid separation.

Preferably, the air intake mechanism of the sweeper further includes a solid baffle 5 , the solid baffle 5 is located on the inner side of the top of the sweeper box 4 , and the solid baffle 5 is connected to the air duct pipe 1 . Export relative settings. The solid baffle can be set at a certain angle with the inner side of the top of the sweeper box, so that the gas discharged from the air duct pipeline can better enter the filter screen after hitting the solid baffle. The gas flow direction is changed by the solid baffle, which enables better filtering of the gas.

Preferably, the outlet of the air duct pipeline 1 faces 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, a huge impact force will be generated. The gas-solid mixture will impact on the top of the settling chamber, and the solid will fall into the settling chamber due to gravity. Bottom, the deposition of solids is achieved.

A vortex is formed. The inlet of the air duct pipeline is relatively set with a vortex generator. When the suction cup absorbs the gas-solid mixture, the vortex generator can generate a local vortex at the inlet of the air duct, which reduces the wind resistance of the air duct and is conducive to the absorption of the gas-solid mixture. On the basis of sucking the gas-solid mixture by the suction cup, the vortex generator further reduces the wind resistance of the air duct, so as to absorb more gas-solid mixture.

Referring to FIG. 3 , the slot hole 211 in this embodiment is a rectangular parallelepiped hole. Since the cuboid holes have a square structure, it is more convenient to manufacture the cuboid holes on the baffle.

Preferably, the number of the slot holes 211 is two or more, and the slot holes 211 are evenly arranged on the baffle plate 21 . The number of slots directly affects the air circulation. The more the number of slots, the larger the air circulation area, the significantly lower the wind resistance of the system, and the lower the energy consumption of the auxiliary engine of the sweeper. In this embodiment, the number of slot holes is 11, which are evenly arranged on the baffle plate. On the one hand, the number of slot holes is large enough, and the air circulation area is large enough, which can effectively reduce the energy consumption of the sweeper engine; On the other hand, the number of slot holes is 11 more convenient for processing.

Preferably, the distance (b) between two adjacent slot holes is 25mm-40mm. The distance between two adjacent slot holes should not be too dense, thus affecting the manufacture of the slot holes. The distance (b) between the two adjacent slot holes is 25mm-40mm, which can make it more convenient to manufacture the slot holes on the baffle plate.

Preferably, the distance (a) from the slot hole 211 to the side edge of the baffle 21 is 30mm-55mm. When cleaning garbage, the arrangement of slot holes directly affects the effect of air circulation. Setting the distance (a) from the slot to the side of the baffle is 30mm-55mm, which can better achieve the effect of air circulation, thereby reducing the consumption of the sweeper engine.

In this embodiment, the inventor also provides a sweeper, including a sweeper air intake mechanism and a vehicle chassis, and the sweeper air intake mechanism is provided on the vehicle chassis. When the sweeper sweeps garbage, the air pressure inside and outside the sweeper is unbalanced because the sweeper air intake mechanism set on the sweeper chassis draws the air inside the sweeper out of the sweeper. In order to maintain the balance of internal and external air pressure, the suction cup of the air intake mechanism of the sweeper operates to absorb the garbage on the ground and suck the garbage into the sweeper, so as to realize the cleaning of the garbage.

Different from the prior art, the above technical solution is provided with slots on the baffle, and the centrifugal fan is used to provide suction for the suction cup; at this time, the local vortex generated at the inlet of the air duct pipeline, Thereby, the take-off speed of the particles is reduced, which is conducive to the absorption of solid particles. At the same time, due to the increase of the overall flow area due to the slotted holes, the wind resistance of the system is significantly reduced, the energy consumption of the auxiliary engine of the sweeper is reduced, and the purpose of energy saving and emission reduction is achieved.
