Abstract
A blower includes: a housing, having an air inlet end and an air outlet end; and a duct assembly disposed in the housing and located between the air inlet end and the air outlet end. The duct assembly includes an outer duct and a motor fan blade assembly disposed in the outer duct. The motor fan blade assembly includes a first motor fan blade assembly and a second motor fan blade assembly; the first motor fan blade assembly includes a first fan blade and a first motor that drives the first fan blade to rotate about a first output axis of the first motor; the second motor fan blade assembly includes a second fan blade and a second motor that drives the second fan blade to rotate about a second output axis of the second motor; and the first output axis is parallel to the second output axis.
Claims17
A blower, comprising:
- a housing, having an air inlet end and an air outlet end;
- and
- a duct assembly disposed in the housing, and the duct assembly is located between the air inlet end and the air outlet end, wherein
- the duct assembly comprises an outer duct and a motor fan blade system, and the motor fan blade system is disposed in the outer duct;
- the motor fan blade system comprises a first motor fan blade assembly and a second motor fan blade assembly;
- the first motor fan blade assembly comprises a first motor and a first fan blade, and the first motor drives the first fan blade to rotate about a first output axis of the first motor;
- the second motor fan blade assembly comprises a second motor and a second fan blade, and the second motor drives the second fan blade to rotate about a second output axis of the second motor;
- and
- the first output axis is parallel to the second output axis;
- wherein the blower further comprises a blowpipe, the blowpipe is connected to the air outlet end, and the blowpipe has a first air guide channel and a second air guide channel that are independent of each other;
- the first motor fan blade assembly communicates with the first air guide channel for allowing air generated by the first motor fan blade assembly to flow along the first air guide channel;
- and the second motor fan blade assembly communicates with the second air guide channel for allowing air generated by the second motor fan blade assembly to flow along the second air guide channel;
- wherein the blower further comprises a nozzle, the nozzle has a connection end and an air outlet opposite to the connection end, the connection end of the nozzle is connected to an end of the blowpipe away from the outer duct, and the nozzle is configured to converge the air flown out from the first air guide channel and the second air guide channel and then flow out the air through the air outlet;
- wherein the air outlet is divided into two independent sub-outlets, and each sub-outlet communicates with one of the air guide channels.
