Joint linkage control structure and laboratory central fresh air control system

Abstract

The invention relates to a joint linkage control structure and a laboratory central fresh air control system. The joint linkage control structure comprises a fresh air treatment cabinet, a detector and a stepping motor, wherein the detector and the stepping motor are arranged on the fresh air treatment cabinet, the stepping motor is connected with an adjusting assembly, the adjusting assembly is connected with a telescopic plate, the telescopic plate matches a fixing plate, the telescopic plate is connected with a moving block by means of a buffering assembly, a first gear is arranged on the moving block, and a driving piece is further arranged on the telescopic plate. The laboratory central fresh air control system comprises a motor, wherein an output shaft of the motor is connected with a bevel gear set, the bevel gear set is connected with a second gear, the motor is further connected with a transmission assembly, the transmission assembly is connected with a fan, the output shaft of the motor is further connected with a forward and reverse rotation assembly, the forward and reverse rotation assembly is connected with a steel wire, the steel wire is provided with an air outlet, the air outlet is connected with a guide assembly, and the air outlet is connected with an exhaust outlet of the fan. The structure and the system are novel in design, simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the field of fresh air control, in particular to a joint linkage control structure and a laboratory central fresh air control system. Background technique [0002] The fresh air system is an independent air treatment system composed of an air supply system and an exhaust system. It is divided into two types: a ducted fresh air system and a ductless fresh air system. The ducted fresh air system is composed of a fresh fan and pipe fittings. Purified outdoor air is introduced into the room, and the indoor air is exhausted through pipes; the ductless fresh air system is composed of fresh fans, which also purify the outdoor air and lead it into the room. Relatively speaking, the ducted fresh air system is more suitable for industrial or large-scale offices due to the large amount of engineering Area use, while the ductless fresh air system is more suitable for home use because of its easy installation; [0003] In the laboratory, d...

Problems solved by technology

[0003] In the laboratory, due to the need for work, it is often necessary to carry out relatively dangerous experiments, resulting in a certain amount of toxic and harmful gases, which will cause harm to the human body if they accumulate in the laboratory for a long time. The traditional treatment method is to put the gas in the laboratory Exhausting the laboratory makes the outside air polluted. Therefore, a joint linkage control structure and a laboratory central fresh air control system are proposed to realize the treatment of the air in the laboratory.
