Technical Field
The invention relates to a personal protection system in a laboratory, in particular to a local air supply system for a human body.
Background
In various research departments and laboratories of colleges and universities, part of pollution and harmful gas is often generated. The existing method for removing indoor polluted gas is ventilation, the polluted gas is controlled in a certain space and discharged through various devices, and the main devices comprise a closed cover, a ventilation cabinet, an external air suction cover, a receiving cover and the like. Although various devices have high efficiency, the actual construction and installation process has high requirements on the quality and technical level of personnel. Because the attention degree of the ventilation facilities in the laboratory is insufficient, the construction units and personnel of the ventilation facilities in the laboratory of various domestic research institutions do not reach the technical standard level, so that the operation efficiency of the ventilation facilities is extremely low and the ventilation facilities are similar to the nominal ones. Polluted gas is diffused in each laboratory, and great threat is caused to the health of indoor personnel.
Disclosure of Invention
In summary, the present invention is directed to a laboratory personal protection system, which is designed to protect the health of laboratory personnel in view of the current situation that laboratory polluted gases cannot be exhausted. The outdoor fresh and clean air is directly sent to the breathing range of a person, and meanwhile, the indoor polluted air is blocked outside the breathing range of the person by using the airflow effect, so that the person directly breathes the outdoor clean air, and the safety of the person is protected.
The purpose of the invention is realized by the following technologies:
a personal protection system in a laboratory consists of an air inlet device and a head air distribution device, wherein the air inlet device consists of a static pressure box, a fan, an electric heating device and a ventilating duct; one end of the fan is communicated with the outside through a ventilating duct, and the other end of the fan is connected with the static pressure box through an electric heating device; the static pressure box is connected with the branch pipe; the branch pipe is connected with a head gas distribution device; the head gas distribution device consists of a head fixing support and a gas distribution device; the front section of the head fixing support is a hollow tube, the front end of the head fixing support is buckled with the front part of a human lower jaw, the rear section of the head fixing support is provided with an ear hook, and the hollow tube is connected with a branch tube through a sleeving hose; the gas distribution device consists of a bronchus and a transverse gas distribution short pipe; one end of the bronchus is communicated with the head fixing bracket through a ball head connecting piece, and the other end is communicated with the transverse gas distribution short pipe through the ball head connecting piece.
The branch pipe is a spiral plastic pipe.
The hose is provided with a gas regulating valve.
The lateral surface of the transverse gas distribution short pipe is distributed with small holes.
The invention has the advantages and beneficial effects that:
1. the invention is suitable for indoor operators with gas pollution and partial particle pollution, so that the indoor operators can suck fresh and clean air, the suction of polluted gas is avoided, and the health of the operators is ensured.
2. The invention is convenient to wear, and because each part does not contact the mouth, cross contamination can not be caused.
3. The air distribution device can flexibly change the direction and range and is suitable for different facial features of people.
4. The invention only consumes energy of the fan and the heater in winter, and has small power and less total energy consumption.
5. The invention has simple structure, flexible and convenient installation, easy acceptance in market and users, convenient popularization and large market potential.
