Abstract
The utility model discloses a dual-purpose blower for blowing and sucking, comprising a blowing port switching mechanism, a suction inlet switching mechanism, a positional arrangement of a big and small suction inlets, an exhaust port and a dust collecting port matched with the main body, a blowing outlet switching slice, and a big and small suction inlet switching slice. Wherein, a switching blower is switched by the blowing port switching mechanism in blowing out mode or sucking in mode. In the blowing out mode, the blowing outlet switching slice is driven to close the dust collecting port by the blowing port switching mechanism, so the air sucked from the suction inlet flows out only through the exhaust port. In the sucking in mode, the blowing outlet switching slice is driven to close the exhaust port by the blowing port switching mechanism, and a majority of air flows in through the big suction inlet with large opening area, so here is a big suction inlet mode. Moreover, a switching control lever is used to drive the suction inlet switching mechanism by the blowing port switching mechanism, and the big and small suction inlet switching slices are driven by the suction inlet switching mechanism to close the big suction inlet, so air flows in only through the small suction inlet. Here, the blower is in a small suction inlet mode. The utility model is capable of being provided with the functions of sucking in mode and blowing away mode.
Description
Technical field
The utility model relates to a kind of blower, especially a kind of pressure-vaccum dual-purpose air blast machine.
