Backpack blower
The invention provides a backpack blower. The backpack blower comprises a backpack assembly, an air inlet assembly fixedly assembled to the backpack assembly and an air outlet assembly connected withthe air inlet assembly, wherein the air inlet assembly comprises an air inlet and an air inlet pipe connected with the air inlet, the air inlet pipe is connected with the air outlet assembly, the backpack blower further comprises a motor duct assembly, and the motor duct assembly is contained in the air outlet assembly. According to the backpack blower, compared with the prior art, when air entersthe backpack blower, an air speed can be reduced when the air passes through a bent pipe, noise can be reduced, the air cannot pass through the bent pipe when the air is blown, and the situation thatthe air speed is reduced when the air is discharged from the bent pipe is avoided, so that the air outlet efficiency is higher.
本发明提供了一种背负式吹风机，包括背负组件、与背负组件组装固定的进风组件以及与进风组件相连的出风组件，所述进风组件包括进风口和与进风口相连的进风管，所述进风管与所述出风组件相连，所述背负式吹风机还包括电机涵道组件，所述电机涵道组件收容在所述出风组件内。相较于现有技术，本发明的背负式吹风机在进风时，风经过弯管会降低风速，有利于降低噪音，而在吹风时不会经过弯管，避免了弯管出风降低风速，这样出风效率更高。
