Cleaning device with alarm function

Abstract

The invention discloses a cleaning device with an alarm function. The cleaning device comprises the components of a bracket which is arranged at one side of a traffic lamp; a water storage box which comprises a box body with an opening at the front side and a front cover that closes the box body, wherein the front cover is made of rubber and is provided with holes; a sponge which is arranged at the front side of the water storage box; a standby lamp box; a standby lamp which is arranged in the standby lamp box and is a red LED lamp; a cylinder which drives the sponge perform periodical reciprocation; and a controller which controls a motor for opening the box cover before each motion period, thereby exposing the standby lamp to outside, and then a power supply circuit is switched on for lighting the standby lamp. Afterwards, the sponge firstly moves backwards in each motion period, and the sponge backwards squeezes the front cover of the water storage box so that water in the water storage box is sprayed out through the holes, thereby wetting the sponge. The sponge then moves frontwards and furthermore contacts with the surface of the traffic lamp. The cleaning device realizes automatic cleaning on the traffic lamp.

Description

technical field [0001] The invention relates to a cleaning device with warning function. Background technique [0002] There are two kinds of traffic lights, which are called motor vehicle lights for motor vehicles, and usually refer to signal lights that are composed of red, yellow, and green (green is blue-green) three-color lights to direct traffic.

Problems solved by technology

[0003] However, because the traffic lights are exposed to the outside world for a long time, it is very easy to be covered with dust

When under direct sunlight or foggy conditions, it is especially difficult to fail to see the color of traffic lights, which will lead to misjudgment by drivers or pedestrians
