Abstract

A vehicle cleaner nozzle injects a cleaning medium on an object to be cleaned which is mounted on a vehicle. The vehicle cleaner nozzle includes a housing, a nozzle chip accommodated in an interior of the housing, and a holder configured to support the housing in a state where the housing accommodates the nozzle chip. A feedback flow path for swinging and injecting the cleaning medium is formed by accommodating the nozzle chip in the housing.

First claim

The invention claimed is:

1. A vehicle cleaner nozzle for injecting a cleaning medium on an object to be cleaned that is mounted on a vehicle, the vehicle cleaner nozzle comprising:
a housing having a first inner wall and a second inner wall that form a first opening portion;
a nozzle chip accommodated in the first opening portion of the housing and having a pair of protruding portions that form an oscillation space therebetween; and
a holder that supports the housing,
wherein a feedback flow path is formed in a space surrounded by the first and second inner walls of the housing and each of the pair of protruding portions, and
wherein the feedback flow path is configured to return a part of the cleaning medium to the oscillation space so as to swing the cleaning medium.

2. The vehicle cleaner nozzle according to claim 1 ,
wherein the vehicle cleaner nozzle is provided in a vicinity of a leading end of a piston accommodated to move back and forth with respect to a cylinder provided in a second opening portion formed in a part of a body panel of the vehicle, and
wherein the vehicle cleaner nozzle is configured to inject the cleaning medium on the object to be cleaned in a state where the piston protrudes from the second opening portion.

3. The vehicle cleaner nozzle according to claim 2 ,
wherein the housing is pivotably attached to the holder, and
wherein the holder is pivotably attached to the piston.

4. The vehicle cleaner nozzle according to claim 3 , wherein rotational axes of the housing and the holder are not parallel to each other.

5. The vehicle cleaner nozzle according to claim 1 , wherein each of the protruding portions has a first surface and a second surface that face the first and second inner walls of the housing, respectively.

6. The vehicle cleaner nozzle according to claim 1 , wherein the first and second inner walls of the housing are perpendicular to each other.
