Abstract:
1. A sucker for attaching an article to an object with an early warning detection function, comprising: a sucker body; a pressure sensor connected with the sucker body; a control circuit board connected with the pressure sensor; and a warning member connected with the control circuit board; wherein: the sucker body has an attachment surface; the control circuit board and the warning member are combined with the pressure sensor; the pressure sensor, the control circuit board and the warning member are mounted in a closed receiving portion; the pressure sensor is connected to the attachment surface of the sucker body; the pressure sensor successively detects and reacts a vacuum leak variation of the attachment surface of the sucker body, and transmits the vacuum leak variation of the attachment surface of the sucker body to the control circuit board; the control circuit board converts the vacuum leak variation of the attachment surface of the sucker body into a feedback signal, and converts the feedback signal into an early warning signal; the control circuit board transmits the early warning signal to the warning member which displays or starts the early warning signal; and the sucker performs an early warning action to provide a safety function.
