A vehicle cleaning device includes a cylinder to which a cleaning fluid is supplied; a piston slidably inserted in the cylinder; a spray nozzle unit mounted at a leading end of the piston and configured to spray the cleaning fluid toward an object-to-be-cleaned; and a cap that closes a gap between the cylinder and the piston in an opening of the cylinder through which the piston protrudes. The cap includes a tubular part inside the cylinder, and the tubular part defines an end of movement of the piston. A communication hole is provided between a communication groove provided in an outer peripheral surface of the tubular part and an inner peripheral surface of the cylinder, and the gap between the cylinder and the piston communicates with the outside of the cylinder through the communication hole.

Vehicle cleaning device, manufacturing method thereof, and assembly method thereof

Of the moving directions of the piston, the direction in which high-pressure air is delivered is a delivery direction, and the direction in the opposite direction from the delivery direction is a force accumulation direction. The piston is moved in the force accumulation direction by the moving mechanism, and moved in the delivery direction by the biasing force of the biasing spring in response to the release of the moving force exerted by the moving mechanism. The cylinder is provided with: a piston supporting portion that supports the piston; and a connection protrusion that has a delivery path for delivering the high-pressure air to the nozzle. The inner surface of an end of the piston supporting portion in the delivery direction is formed as a closed surface. The delivery path is located further toward the force accumulation direction than the closed surface is.

Foreign body removal device and drive device for foreign body removal device

A vehicular cleaner system () for cleaning a to-be-cleaned object (), wherein: the vehicular cleaner system () is provided with a tank () that accommodates a cleaning liquid, a pump () that pressure-feeds the cleaning liquid inside the tank (), a high-pressure-air generation unit () that generates high-pressure air, a first ejection port that sprays the cleaning liquid toward a cleaning surface of the to-be-cleaned object (), a second ejection port that sprays the high-pressure air toward the cleaning surface, and a controller () and vehicle ECU () that control the spraying of the cleaning liquid and the spraying of the high-pressure air; and the controller () and the vehicle ECU () perform control so as to initiate the spraying of the high-pressure air from the second ejection port after spraying of the cleaning liquid from the first ejection port has been initiated.

Vehicular cleaner system, vehicle having vehicular cleaner system, vehicular cleaner and vehicle having vehicular cleaner

A vehicle cleaner includes a cylinder, a piston, a nozzle holder, a nozzle and a nozzle cover. The nozzle cover includes a cover portion that closes an opening formed in a part of a vehicle body panel of a vehicle, and an engaging portion that protrudes from the cover portion toward the piston and engages with the nozzle holder. The engaging portion is provided with a concave portion for lance engagement on one surface, and an abutting rib on the other surface of the engaging portion opposite to the one surface. The nozzle holder is provided with a first convex portion that engages with the concave portion on one surface, and a first abutted rib against which the abutting rib abuts on the other surface of the nozzle holder opposite to the one surface.

Vehicle cleaner

A vehicle washing device includes: a cylinder including a cylinder tube to which a washing fluid is supplied; a piston including a piston tube that is movably inserted into the cylinder tube and opens at both ends; and a spray nozzle that is mounted at a leading end, in an extension direction, of the piston tube protruding from the cylinder tube. The spray nozzle is configured to spray the washing fluid, supplied through the inside of the piston tube, toward an object-to-be-washed. The outer circumference of the spray nozzle is fitted on the inner circumference of the piston tube.

Vehicle washing device

A foreign matter removal device () is configured to remove foreign matters on a lens () of an in-vehicle camera () attached to a vehicle so that the lens () of the in-vehicle camera () is exposed toward an outside of a body panel of the vehicle. The foreign matter removal device includes a single-cylinder type reciprocating pump () configured to generate high-pressure air and a nozzle () configured to inject the high-pressure air toward the lens (). A volume of an internal space of the pump is 10 cmor less. Exhaust time (t) per cycle required for exhausting the air in the internal space is 0.03 seconds or less.

Foreign material removing device and vehicle provided with this foreign material removing device

A cleaner for cleaning an object to be cleaned includes a generation unit configured to generate high-pressure air, a nozzle configured to inject the high-pressure air toward a cleaning surface of the object to be cleaned, and a control unit configured to control an injection of the high-pressure air. Even when foreign objects do not adhere to the cleaning surface, the control unit executes an operation mode in which the high-pressure air is generated and injected when a predetermined condition is satisfied.

Cleaner, sensor with cleaner, and vehicle including cleaner or sensor with cleaner

Provided is an air cleaner for vehicles, configured so that objects to be cleaned can be easily maintained in as clean state. This fair cleaner () for vehicles is provided with: ejection openings () for ejecting air toward the surfaces () to be cleaned of objects () to be cleaned and a non-positive displacement blower means () for continuously delivering air to the ejection openings ().

Air cleaner for vehicles

A foreign matter removal device that removes foreign matters adhering to a lens () included in an in-vehicle camera (), including a camera bracket () that attaches the in-vehicle camera () to a rear bumper panel () of a vehicle in a state in which the lens () is exposed toward the outside of the rear bumper panel () of the vehicle, a high-pressure air generation unit disposed inside the rear bumper panel () and configured to generate high-pressure air, and a nozzle unit provided with a nozzle () that injects the high-pressure air toward the lens (), wherein a through-hole () is formed in the camera bracket (), and the high-pressure air generated by the high-pressure air generation unit passes from the inside to the outside of the rear bumper panel () through the through-hole (), and is injected from the nozzle () toward the lens ().

Foreign matter removal device and vehicle equipped with foreign matter removal device

Of moving directions of a piston, the direction in which high-pressure air is delivered is a delivery direction, and the direction in the opposite direction from the delivery direction is a force accumulation direction. The piston is moved in the force accumulation direction by the moving mechanism, and moved in the delivery direction by the biasing force of the biasing spring in response to the release of the moving force exerted by the moving mechanism. The cylinder is provided with: a piston supporting portion that supports the piston; and a connection protrusion that has a delivery path for delivering the high-pressure air to the nozzle. The inner surface of an end of the piston supporting portion in the delivery direction is formed as a closed surface. The delivery path is located further toward the force accumulation direction than the closed surface is.

Structural simplification and efficient injection state of high-pressure air from a nozzle are ensured. A foreign material removal device is provided with: a cylinder () into which air is caused to flow; a piston () which is movably supported in the cylinder and feeds the air introduced into the cylinder in a feeding direction as high-pressure air; and a nozzle () which injects the high-pressure air fed by the piston. Thus, the piston is moved relative to the cylinder, the high-pressure air is fed from the cylinder, and the high-pressure air is injected from the nozzle, whereby structural simplification and an efficient injection state of the high-pressure air from the nozzle can be ensured.
