Abstract

This utility model provides a cleaning device for car door handles and a vehicle, relating to the field of vehicle cleaning technology. The cleaning device for car door handles includes: at least one nozzle structure, at least one delivery channel, and a medium pressurizing structure. The medium pressurizing structure pressurizes the cleaning medium and inputs the pressurized cleaning medium into the delivery channel. The first end of the gradually expanding cavity of the nozzle structure is connected to the delivery channel, which inputs the cleaning medium into the gradually expanding cavity through the first end. The second end of the gradually expanding cavity is the outlet end of the cleaning medium, and the diameter of the first end of the gradually expanding cavity is smaller than the diameter of the second end. The extension line of the direction in which the cleaning medium is ejected from the outlet end is parallel or nearly parallel to the outer surface of the car door handle. The cleaning medium ejected through the outlet end is a planar fluid that cleans the outer surface of the car door handle. This solution improves the cleaning efficiency of the outer surface of the car door handle, and the control and cleaning methods are simple and easy to operate.
