Description

Umbrella with warning function

Technical Field

The utility model relates to an umbrella technical field, in particular to umbrella with warning function.

Background

The umbrella is an indispensable article in life and is used for rain shielding or sun shading. Most of the current umbrellas only have the function of rain shielding or sun shielding, or the umbrella cover is made into various patterns or colors to increase the aesthetic property. However, in rainy days or at night, the umbrella with the dark umbrella cover is not easy to be found due to weak light, so that traffic accidents are easily caused. Therefore, an umbrella with a warning function is proposed, for example, chinese patent application No. 201510231536.9 discloses an umbrella with a flashlight, the LED flashlight is arranged at the umbrella edge, and the battery built in the handle of the umbrella supplies power to illuminate, so that pedestrians can be easily found by motor vehicles on the road when walking in rainy days, and traffic accidents can be effectively avoided. However, the service life of the battery is limited, the battery needs to be replaced frequently in a battery power supply mode, if the umbrella does not have power in the using process, the umbrella does not have a light-emitting warning function any more, the cost is high due to frequent replacement of the battery, and environmental pollution is caused due to replacement of the lost battery.
