Battery-powered backpack blower
The battery-powered backpack blower includes a back support assembly including a back plate configured to permit a user to mount the blower to the user's back, and a volute assembly including a first volute portion and a second volute portion. The backpack blower further includes a housing assembly including a battery assembly and a motor assembly therein, the housing assembly is provided intermediate to the back assembly and the volute assembly.
1. A method for using a backpack blower, comprising the steps of:
providing a blower having a backplate, a volute assembly for providing an air flow pathway through the blower, a fan member to generate air flow through the volute assembly, a motor secured to the volute assembly and operatively connected to the fan member, the motor being powered by at least one battery, a first battery well configured to receive a first battery and a second battery well, spaced from the first battery well, configured to receive a second battery;
inserting the first battery into the first battery well and inserting the second battery into the second battery well; and
placing the blower on a user's back for use.
2. The method of claim 1 , wherein the motor is located between the first battery well and the second battery well.
3. The method of claim 1 , wherein the first battery well is disposed above the second battery well.
4. The method of claim 1 , wherein the volute assembly is disposed substantially parallel with the backplate.
5. The method of claim 1 , wherein the first and second batteries are inserted through a side of the blower.
6. The method of claim 1 , further comprising the step of providing a control assembly with a trigger to control power to the motor; and
depressing the trigger to provide power to the motor.
7. A method of operating a backpack blower, comprising the steps of:
providing a blower with a backplate defining a first plane, a harness attached to the backplate, a volute assembly for providing an air flow pathway through the backpack blower, the volute assembly lying in a second plane, wherein the first plane and the second plane are substantially parallel, a motor operatively connected to a fan member, the motor being powered by at least one battery, a fan member to generate air flow through the volute assembly, and a first battery well to hold a first battery;
inserting the first battery into the first battery well; and
placing the blower on a user's back.
8. The method of claim 7 , wherein the blower has a second battery and a second battery well, further comprising the step of inserting the second battery into the second battery well.
9. The method of claim 8 , wherein a vertical axis going through a first battery center of gravity and a vertical axis going through a second battery center of gravity do not lie in the same plane.
10. The method of claim 7 , wherein the volute assembly has an air intake facing a rearward direction.
