3D printing clean environment control device and control method based on micro differential pressure

Abstract

The invention discloses a 3D printing clean environment control device and control method based on micro differential pressure. The 3D printing clean environment control device comprises a disinfection and sterilization device I, a disinfection and sterilization device II, a micro differential pressure sensor, a flow sensor and an air inlet pump which are in communication connection with a controlmodule. The disinfection and sterilization device I is arranged in a 3D printing forming chamber. The micro differential pressure sensor is arranged in the 3D printing forming chamber, and one of twoinput ends of the micro differential pressure sensor is arranged indoors, and the other one is arranged outdoors. The air inlet pump is arranged outside the 3D printing forming chamber, and an air inlet and an air outlet are correspondingly formed in the 3D printing forming chamber. Air output by the air inlet pump sequentially passes through the disinfection and sterilization device II and the flow sensor to reach the air inlet and then enters the 3D printing forming chamber. The air outlet is used for exhausting the air. Through timing sterilization and the micro pressure difference technology for automatic detection of the indoor and outdoor pressure difference, the indoor air is supplemented or exhausted, the air and environment quality in the 3D printing forming chamber can be guaranteed, and the 3D printing work quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of environmental control, in particular to a 3D printing clean environment control device based on micro-pressure difference. Background technique [0002] The 3D printing molding room requires a clean environment. At present, ultraviolet and ozone methods are mainly used for disinfection and sterilization, and the molding room is sealed with sealing strips. Although this method can sterilize the air inside the molding chamber, problems such as the aging of the sealing strip will cause external air to leak into the molding chamber, causing the air in the molding chamber to be polluted and a clean environment cannot be guaranteed. Contents of the invention [0003] A 3D printing clean environment control device and control method based on micro-pressure difference proposed by the present invention can solve the above-mentioned defects in the background technology. [0004] To achieve the above object, the ...
