Garden blower
The invention provides a garden blower. The garden blower comprises an air duct pipe body, a fan, a motor and a current collector connected to one end of the air duct pipe body; the fan is coaxially arranged in the air duct pipe body; the motor is arranged outside the air duct pipe body; the fan comprises a fan blade inner ring; a reversing transmission mechanism is arranged between the motor and the fan; the reversing transmission mechanism comprises a driving piece and a driven piece; the driving piece is connected with the motor; and the driven piece is connected with the fan blade inner ring. According to the invention, the motor is arranged outside the air duct pipe body, and the diameter of the fan blade inner ring can be reduced as much as possible, so that smooth ventilation of the air duct pipe body can be guaranteed, and the actual ventilation area of the air duct of the air duct pipe body is increased; and after the diameter of the fan blade inner ring is reduced, the distance from the outer wall of the fan blade inner ring to the inner wall of the air duct pipe body is increased, and the length of the fan blade can be designed as long as possible, so that the air speed and the air volume of the air duct in the air duct pipe body are greatly increased.
本发明提供了一种园林吹风机，园林吹风机包括风道管体、风扇、电机和连接在风道管体一端的集流器，风扇同轴设于风道管体内，电机设于风道管体外，风扇包括风叶内圈，电机与风扇之间设有换向传动机构，换向传动机构包括主动件和从动件，主动件与电机连接，从动件与风叶内圈连接。本发明中将电机设置在风道管体外，可以尽量缩小风叶内圈的直径，这样既能保证风道管体通风顺畅，又增加了风道管体的风道实际通风面积；且风叶内圈的直径减小后，也就增加了风叶内圈外壁到风道管体内壁的距离，可以将风扇的叶片长度设计地尽量长，从而大大增加风道管体内风道的风速和风量。
