Embodiment Construction

[0029] A lamp cleaning device 1 according to the present invention comprises a cylindrical elongated housing 2 and a retractable hollow cleaning fluid supply tube 4, the cylindrical elongated housing 2 being formed to be connectable to a pressurized cleaning fluid source (not shown). The inlet 3 of the hollow cleaning fluid supply pipe 4 is slidably arranged in the housing 2 .

[0030] Although the lamp cleaning device 1 according to the invention is referred to as a headlight cleaning device, it can also be used as a cleaning device for a windscreen or other surface to be cleaned.

[0031] It should be understood that the lamp cleaning device 1 may be mounted in a concealed manner on a vehicle structure, for example in a bumper of a car. The inlet 3 is connected to a cleaning liquid supply pipe not shown. The cleaning liquid will be supplied through the supply pipe from an electrically operated cleaning liquid pump. The housing 2 is provided with a mounting bracket 5 for mo...

Abstract

The invention refers to a headlamp cleaning device for motor vehicles comprising an elongate housing (2) formed with an inlet port (3) connectable to a source of pressurized cleaning fluid and a retractable hollow cleaning liquid supply tube (4) slidably arranged within the housing (2) and being biased in the retracted position, at least one spray nozzle (6) provided at the distal end of the cleaning fluid supply tube (4) and a fluid valve (22) at the proximal of the cleaning liquid supply tube (4) allowing ingress of the cleaning fluid into the tube once the fluid pressure exceeds a predetermined amount, the fluid valve being designed as a resilient closure cap which at the same time functions as a piston seal for the cleaning fluid supply tube (4) (FIG. 3).

Description

technical field [0001] The present invention relates to a light cleaning device, in particular to a headlight cleaning device for a motor vehicle comprising: an elongated housing forming an inlet connectable to a source of pressurized cleaning fluid; a retractable a hollow cleaning liquid supply tube slidably disposed in the housing and biased in a retracted position; at least one nozzle disposed at a distal end of the cleaning fluid supply tube; and a fluid valve , which is located at the proximal end of the cleaning fluid supply tube, the fluid valve allows cleaning fluid to enter the cleaning fluid supply tube when the fluid pressure exceeds a predetermined amount. Background technique [0002] Such telescoping headlight cleaning devices are generally known in the art. The telescoping headlight cleaning device is usually arranged in a concealed manner under a part of the vehicle structure, for example by a cover or cover in the bumper of the vehicle.
