Abstract

The invention discloses a door closer capable of automatically opening or closing a door. The door closer comprises a pedestal, a door closer cylinder body arranged on the pedestal, a rocker arm rotatably connected with the door close cylinder body through a pivot, a driving component capable of driving the pivot to rotate and a control component of controlling the driving component to operate. The door closer of automatically opening or closing the door has the advantages that (1) a sensing part is utilized to detect whether a person is close to the door or not, a processor is utilized to control to open or close the door, the use is convenient, and it is avoided that a handle of the door can cause disease spread when people pull the door handle; (2) the sensing part and a time relay areadopted to control the time of opening the door, thereby avoiding pinching hand when the door is closed earlier; (3) when the electricity of the door closer of automatically opening or closing a dooris cut off, a dead lock can not happen on the door closer, and the door can be opened or closed by hand.

Description

technical field [0001] The invention relates to a door closer, in particular to an automatic door closer. Background technique [0002] Existing leaf doors are generally hinged on the door frame through hinges or hinges.
