Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, a kind of exhaust fan device applied to vacuum cleaner of the utility model, including shell
210, the shell 210 is provided with inner cavity, and top is provided with cover board 220；The bottom of the shell 210 is provided with suction inlet 211,
The suction inlet 211 is connected with inclined dedusting channel 212；Being internally provided with for shell 210 is used to support dust-collecting box
Inner housing 213；Connecting cylinder 214 is provided at the lumen centers of the shell 210, the bottom of the connecting cylinder 214 is provided with pumping
Blower 215.
Such as the dust-collecting box that Fig. 3, Fig. 4 and Fig. 6 and this exhaust fan matched with devices use, including box body 110 and box cover 120, institute
It states and is provided with dust-collecting cavity 112 in box body 110, the box cover 120 is set to the top of box body 110, and one side of box cover 120 and box
Body 110 is hinged, other sides are fastened and connected with box body 110；The upper surface of the box cover 120 is provided with handle 121, and can facilitate will collect
Dirt box takes out；The side wall of the box body 110 is provided with entering-dust mouth 111；Exhaust tube 113 is provided in the dust-collecting cavity 112, it is described
The top of dust-collecting cavity 112 is provided with filter screen 114, and filter screen 114 is run through in the upper end of the exhaust tube 113, and box body is run through in lower end
110 bottom wall.Dedusting channel 212 export shape and box body 110 111 shape adaptation of entering-dust mouth, the size of connecting cylinder 214 with
Exhaust tube 113 is adapted, as shown in figure 5, entering-dust mouth 111 and dedusting channel 212 are right after dust-collecting box is packed into exhaust fan device
It connects, meanwhile, exhaust tube 113 is docked with connecting cylinder 214, in use, opening exhaust fan 215, exhaust fan 215 passes through connecting cylinder 214
The air inside dust-collecting cavity 112 is sucked out with exhaust tube 113, dust-collecting cavity 112 is in negative pressure state, sweeping the floor at suction inlet 211
Brush cleans ground, and the dust of generation is under the action of ambient pressure by suction inlet 211, dedusting channel 212 and into dirt
Mouthfuls 111 enter dust-collecting cavities 112, and since the top of dust-collecting cavity 112 again is provided with filter screen 114, the dust in dust-collecting cavity 112 will not
Into exhaust fan 215, it is ensured that the smooth operation of exhaust fan 215.
The top edge of the box body 110 is provided with outside support flange 117, the inner wall setting at 213 top of inner housing
There is support level 216, when installing dust-collecting box, the support flange 117 of box body 110 is placed on to the support level 216 of inner housing 213
On, it is ensured that the stabilization of dust-collecting box.
The inner wall of the box body 110 is provided with support ladder 115, and the edge of the filter screen 114 is provided with L-shaped positioning
Frame 116, the horizontal position of the posting 116 is in the upper surface of support ladder 115, the inner wall compression of vertical portion and box body 110
