Abstract

An electric blower is configured to blow air. The blower includes a body configured such that a sprayer attachment is attachable thereto. The body is configured to be carried integrally with the sprayer attachment with the sprayer attachment attached to the body. The sprayer attachment includes a container, a nozzle and a liquid supply passage. The container is configured to store a liquid. The nozzle has a discharge opening. The liquid supply passage is connected to the container and the nozzle to lead the liquid.

Claims (56)

1. An electric blower configured to blow air, comprising:

a body configured such that a sprayer attachment is attachable to the body, the sprayer attachment including a container configured to store a liquid, a nozzle having a discharge opening, and a liquid supply passage connected to the container and the nozzle and configured to transport the liquid from the container to the nozzle;

a motor; and

a fan configured to be rotated by the motor and to blow air from the discharge opening of the nozzle when the sprayer attachment is attached to the body,

wherein:

the body includes:

a housing part (i) that houses the motor and the fan, (ii) extending along a rotation axis of the motor and the fan that defines a front-rear direction of the blower, and (iii) having a nozzle-mounting part to which the nozzle is attachable at a front end of the housing part in the front-rear direction;

a grip part (i) configured to be held by a user, (ii) protruding from the housing part generally in an up-down direction of the blower that is perpendicular to the front-rear direction and (iii) having an upper end connected to the housing part and a lower free end spaced from the housing part in the up-down direction; and

a battery-mounting part (i) connected to the lower free end of the grip part, (ii) spaced from the housing part, (iii) configured to removably receive a battery for supplying power to the motor, and (iv) having at least one container-mounting part to which the container is attachable;

the container has (i) a container longitudinal axis, (ii) a first closed axial end and (iii) a second open axial end; and

the at least one container-mounting part is configured to removably receive the container such that, when the container is attached to the at least one container-mounting part, the container longitudinal axis is generally in the up-down direction and the second open axial end is directed upward in the up-down direction.

2. The blower as defined in claim 1 , wherein the at least one container-mounting part includes a plurality of container-mounting parts at different positions on the battery-mounting part.

3. The blower as defined in claim 2 , wherein:

the nozzle-mounting part has a nozzle-mounting part longitudinal axis;

the grip part has a grip part longitudinal axis;

the plurality of container-mounting parts include two container-mounting parts on both sides of a plane containing the nozzle-mounting part longitudinal axis and the grip part longitudinal axis; and

the nozzle-mounting part is configured such that the nozzle is selectively attachable to either one of two nozzle attachment positions that are different in a circumferential direction around the nozzle-mounting part longitudinal axis.

4. The blower as defined in claim 3 , further comprising:

a holder (i) configured to removably hold the container and (ii) that is a separate component from the body,

wherein:

the holder is selectively removably fixed to one of the two container-mounting parts, and

each of the two container-mounting parts is configured to removably receive the container via the holder.

5. The blower as defined in claim 1 , further comprising:

wherein the at least one container-mounting part is on a side portion of the battery-mounting part.

6. The blower as defined in claim 1 , further comprising:

a holder (i) configured to removably hold the container and and (ii) that is a separate component from the body,

wherein:

the holder is removably fixed to the at least one container-mounting part, and

the at least one container-mounting part is configured to removably receive the container via the holder.

7. The blower as defined in claim 6 , wherein the holder includes:

a fixed part removably fixed to the at least one container-mounting part; and

a movable part configured to removably hold the container and connected to the fixed part to be movable relative to the fixed part.

8. The blower as defined in claim 7 , wherein the movable part is rotatably connected to the fixed part.

9. The blower as defined in claim 1 , further comprising the sprayer attachment,

wherein:

the container is attached to the at least one container-mounting part; and

the nozzle is attached to the nozzle-mounting part.

10. The blower as defined in claim 9 , wherein the container is configured to be attached to and detached from the at least one container-mounting part without need for using an auxiliary tool.

11. The blower as defined in claim 9 , wherein the sprayer attachment further includes a valve configured to open and close the liquid supply passage in response to manipulation of the valve by a user.

12. The blower as defined in claim 9 , wherein one end portion of the liquid supply passage has a connecting part configured to be removably connected to the nozzle.

13. The blower as defined in claim 12 , wherein the container has a holding part configured to removably hold the connecting part of the liquid supply passage.

14. The blower as defined in claim 13 , wherein:

the container has a vent hole communicatively connecting an inside of the container to an outside of the container, and

the holding part defines at least a portion of the vent hole of the container and is configured to receive the connecting part fitted therein.

15. An electric blower and sprayer assembly, comprising:

an electric blower (i) configured to blow air and (ii) including a body, a motor and a fan configured to be rotated by the motor; and

a sprayer attachment (a) attached to the body and (b) including a container (i) configured to store a liquid and (ii) having a container longitudinal axis, a first closed axial end and a second open axial end, a nozzle configured to discharge the liquid through a discharge opening of the nozzle, and a liquid supply passage connected to the container and the nozzle and configured to transport the liquid from the container to the nozzle, wherein:

the electric blower is configured such that the fan causes the air to discharge through the discharge opening when the fan is rotated by the motor;

the body includes:

a housing part (i) that houses the motor and the fan, (ii) that extends along a rotation axis of the motor and the fan that defines a front-rear direction of the electric blower and (iii) having a nozzle-mounting part at a front end of the housing part in the front-rear direction;

a grip part (i) configured to be held by a user, (ii) protruding from the housing part (a) in an up-down direction that is perpendicular to the front-rear direction and (b) away from the motor and the fan and (iii) having an upper end connected to the housing part and a lower free end spaced from the housing part; and

a battery-mounting part (i) connected to the lower free end of the grip part, (ii) spaced from the housing part, (iii) configured to removably receive a battery and (iv) having at least one container-mounting part;

the nozzle is attached to the nozzle-mounting part;

the container is attached to the at least one container-mounting part;

the container longitudinal axis is in the up-down direction; and

the second open axial end is directed upwardly in the up-down direction.
