Garden Blower

A garden blower, comprising:

• a housing having an air inlet end and an air outlet end;
• and
• a main air path component, comprising a duct assembly, and forming a main air path suitable for airflow to flow from the air inlet end to the air outlet end at high speed, an accommodating chamber being formed between the main air path component and the housing, and an electronic device being provided in the accommodating chamber, and the electronic device comprising a controller,
• wherein the duct assembly comprises an outer duct and a motor fan blade assembly arranged 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 connected to the accommodating chamber between the outer duct and the rear casing, 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 the rear casing is provided with an installation port, the controller is embedded in the installation port for positioning;
• wherein during operation of the garden blower, the heat emitted by the electronic device flows from the accommodating chamber into the main air path through the negative pressure inlet;
• 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, and during operation of the garden blower, the outer duct and the holding casing are not in direct contact;
• wherein the first anti-vibration component is close to the motor fan blade assembly and forms a first anti-vibration plane perpendicular to a motor axis of the motor fan blade assembly;
• the first anti-vibration plane is parallel to a direction of an exciting force of the vibration generated by the motor fan blade assembly.
