Abstract

A headlamp cleaner includes a tank in which a cleaning fluid is stored, a motor pump which pumps the cleaning fluid stored inside the tank, a fluid path through which the cleaning fluid pumped by the motor pump is pressure-transferred, and a nozzle from which the cleaning fluid pressure-transferred through the fluid path is ejected toward a headlamp. The fluid path mainly includes a hose made of a rigid material such as plastic.

Claims

1. A headlamp cleaner comprising:

a tank in which a cleaning fluid is stored;

a motor pump which pumps the cleaning fluid stored inside the tank;

a fluid path through which the cleaning fluid pumped by the motor pump is pressure-transferred; and

a nozzle from which the cleaning fluid pressure-transferred through the fluid path is ejected toward a headlamp,

wherein the fluid path comprises a hose made of plastic.

2. The headlamp cleaner according to claim 1, wherein at least a part of the hose is corrugated such that an internal sectional area of the fluid path in a radial direction thereof gradually changes along a longitudinal direction of the fluid path.

3. The headlamp according to claim 2, wherein the corrugated part of the hose comprises an internal convex portion including, at a middle portion thereof, a region where the internal sectional area of the fluid path in the radial direction becomes a minimum, and wherein a section of the internal convex portion along the longitudinal direction of the fluid path is curved.

4. The headlamp according to claim 2, wherein the corrugated part of the hose comprises:

an internal concave portion including, at a middle portion thereof, a region where the internal sectional area of the fluid path in the radial direction becomes a maximum; and

an external concave portion including, at a middle portion thereof, a region where an external sectional area of the fluid path in the radial direction becomes a minimum,

wherein sections of both the internal concave portion and the external concave portion along the longitudinal direction of the fluid path are curved.

5. The headlamp according to claim 3, wherein the corrugated part of the hose further comprises:

an internal concave portion including, at a middle portion thereof, a region where the internal sectional area of the fluid path in the radial direction becomes a maximum; and

an external concave portion including, at a middle portion thereof, a region where an external sectional area of the fluid path in the radial direction becomes a minimum,

wherein sections of both the internal concave portion and the external concave portion along the longitudinal direction of the fluid path are curved.

6. The headlamp cleaner according to claim 1, further comprising another nozzle from which the cleaning fluid pressure-transferred through the fluid path is ejected toward another headlamp,

wherein the fluid path further includes a branched portion, and

the hose includes a first hose portion connecting the motor pump and the branched portion, a second hose portion connecting the nozzle and the branched portion, and a third hose portion connecting the another nozzle and the branched portion.
