When not in use, the charging cable is inserted into the shell through the spring to achieve the effect of hiding the charging cable, avoiding the phenomenon of the charging cable being entangled and affecting the user experience, thereby improving the user experience. By setting an LED sensor, when a gas sensor is used to detect carbon monoxide and other gases in a nearly enclosed space such as a car, the car has a certain sound insulation effect. There is a risk that a person outside the car fails to hear the alarm and then enters the car to cause a safety accident. By setting an LED sensor to add a warning method, the possibility of the driver seeing the warning is increased, thereby enhancing the prompt effect. BRIEF DESCRIPTION OF THE DRAWINGS
