Abstract
A light cleaning device for washing lights located on an external portion of a vehicle. The device has an elongate housing formed with an inlet port connectable to a source of pressurized liquid and a rinsing head fitted with at least one jet nozzle. The jet nozzle is mounted at a distal end of a telescopically retractable hollow tube of the device, which is normally retracted. There is a liquid flow path from the housing to the rinsing head which can emit a jet spray therefrom when the tube is projected from the housing. The nozzle may have a jet forming member fitted therein to turbulate the jet spray fluid.
Claims23
A vehicle light cleaning device comprising an elongate housing formed with an inlet port connectable to a source of pressurized rinsing liquid, a rinsing head fitted with at least one jet nozzle and mounted at a distal end of a telescopically retractable hollow tube, said tube being normally retracted;
- a liquid flow path extending between said rinsing head and an inside space of the housing;
- a normally closed sealing assembly adapted to open the liquid flow path only responsive to full projection of the tube from the housing.
A liquid jet nozzle for use with a vehicle light cleaning device, the jet nozzle comprising a housing and a jet forming member fitted therein;
- the housing being formed with a spherical portion swivellingly received within a corresponding rinsing head of the cleaning device, and a jet emitting portion;
- the jet forming member dividing the spherical portion of the housing into a liquid inlet chamber and a liquid swirl chamber, said liquid swirl chamber being in flow communication with the jet emitting portion through an axial aperture formed with said housing and wherein a liquid flow path extends between the liquid inlet chamber and the liquid swirl chamber, said liquid flow path comprising at least one tangential duct directing liquid radially inwards into the swirl chamber.
A liquid jet nozzle for use with a vehicle light cleaning device, the jet nozzle comprising a housing and a jet forming member fitted therein;
- the housing being formed with a spherical portion swivellingly received within a corresponding rinsing head of the cleaning device, and a jet emitting portion;
- the jet forming member dividing the spherical portion of the housing into a liquid inlet chamber and a liquid swirl chamber;
- said liquid swirl chamber being in flow communication with the jet emitting portion by at least one axial aperture formed with said housing, and with the liquid inlet chamber by at least one duct formed with the jet forming member tangentially extending into the swirl chamber.
