1. A garden blower, comprising:
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,
wherein the duct assembly comprises an outer duct, a motor fan blade assembly and a guide cone, and the motor fan blade assembly and the guide cone are disposed in the outer duct;
wherein the outer duct and a rear casing of the housing are arranged in such a way that there is an annular interval therebetween, and the outer duct and the rear casing are deliberately set at a safe distance from each other so as to maintain an absolute non-contact state, forming a negative pressure inlet, thereby whether it is rotation vibration of the motor fan blade assembly or disturbance of the rear casing due to the airflow, the outer duct and the rear casing would not contact each other, and thereby no vibration superposition would be generated;
wherein a first anti-vibration component is provided between the outer duct and a holding casing of the housing, so that the outer duct and the holding casing are spaced apart by the first anti-vibration component to maintain a state of non-direct contact;
wherein the first anti-vibration component is close to the motor fan blade assembly and is situated on a first anti-vibration plane perpendicular to a motor axis of the motor fan blade assembly and parallel to a direction of an exciting force of the vibration generated by the motor fan blade assembly, and wherein the first anti-vibration plane passes through the motor fan blade assembly and/or a holding handle located above the motor fan blade assembly;
wherein a second anti-vibration component is provided between one end of the outer duct, away from the motor fan blade assembly and the holding casing, so that the outer duct and the holding casing are spaced apart by the second anti-vibration component to maintain a state of non-direct contact;
wherein the second anti-vibration component is situated on a second anti-vibration plane parallel to and non-coincident with the first anti-vibration plane, and wherein the guide cone is at least partially located between the first anti-vibration plane and the second anti-vibration plane;
wherein under the rotation of the motor fan blade assembly, air is capable of flowing at high speed from the air inlet end to the air outlet end, and wherein an accommodating chamber connected to the negative pressure inlet is provided between the rear casing and the holding casing, and a controller is provided in the accommodating chamber;
wherein the rear casing is provided with an installation port, and the controller is embedded in the installation port for positioning;
wherein the outer duct comprises a support end located at the air outlet, the support end is configured to support a cone end of the guide cone, the other end of the guide cone is connected to a motor seat, and the second anti-vibration component is sandwiched between an outer wall of the support end and an inner wall of the holding casing.
