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. This rotating leaf door is opened and closed by pushing and pulling the leaf door to make the door leaf rotate around the hinge shaft to achieve the purpose of opening and closing the door. This fan door has following shortcoming: (1) people will push or pull the door leaf when going in and out, and when the person who goes in and out has something in his hand, he will put it down first, and then open or close the door, which is inconvenient to use. (2) Everyone has to push or pull the door leaf by hand when entering and exiting. The door handle becomes a medium for spreading diseases and is extremely unhygienic. Contents of the invention [0003] The purpose of the present invention is in order to overcome the shortcoming of prior art, provide a kind...
