Document Type and Number:
Japanese Patent JP5494743
Kind Code:
B2
Abstract:
A camera washing device has an air pump, a wash water tank storing wash water, an injection nozzle with an injection part, a junction joint having a high-pressure air passage and a wash water passage, and an electromagnetic valve. The air pump generates and supplies high-pressure air to the high-pressure air passage. When the control part instructs the electromagnetic valve to be switched to an open state, the wash water and the high-pressure air are mixed in the junction joint to generate water particles. The generated water particles are supplied to the injection nozzle. When the electromagnetic valve is switched to the open state after injecting the high-pressure air only to a lens of a rear camera, the injection part injects the water particles to the lens of the camera.
