Abstract

The utility model discloses a respiration bin of a bin-type positive-pressure oxygen respirator, and relates to a respiration bin for life saving appliance. In order to solve the problem of long pipeline and large respiration resistance of the prior bin-type positive-pressure oxygen respirator, the respiration bin of the bin-type positive-pressure oxygen respirator comprises an annular bin, a exhalation pipe hole formed on the wall of the annular bin, an inspiration pipe hole, an oxygen supply pipe hole, and a separator arranged at the middle part of the bin for dividing the annular bin into an upper bin and a lower bin, wherein a large hole is formed on the separator; the exhalation pipe hole is communicated with the lower bin; and the inhalation pipe hole is communicated with the upper bin. The respiration bin can accommodate a cooling tank within so as to reduce pipe connection and enhance the comfort in respiration.

Description

Storehouse formula positive pressure oxygen respirator is breathed the storehouse

Technical field

The utility model relates to a kind of lifesaving appliance and breathes the storehouse, is specially a kind of storehouse formula positive pressure oxygen respirator and breathes the storehouse.

Background technology

The positive pressure oxygen respirator that public mine rescue and fire-fighting, chemical defence are used is a kind of closed circuit respiratory circulatory system that is hedged off from the outer world, and the time wears for people operation or rescue in the toxic and harmful environment.Owing to be hedged off from the outer world, whole respiratory system is closed cycle, during use, and the carbon dioxide CO that human body is breathed out ₂With the Ca (OH) in the peace and quiet jar ₂The gas and the oxygen mix that produce behind the generation chemical reaction, the oxygen gas mixture in the time of can providing human body respiration.Present storehouse formula positive pressure oxygen respirator mostly is annular and breathes the storehouse, breathes the middle part, storehouse and is divided into upper and lower storehouse two parts by dividing plate, is communicated with by the cannelure of breathing on the bulkhead between the upper and lower storehouse.Gas enters through exhaust tube and breathes on the storehouse storehouse exhalation vents to dividing plate during expiration, behind peace and quiet jar of removal carbon dioxide, gas is gone into Xia Cang from breathing storehouse circumferential annular concentrated flow, producing by voltage stabilizing membrane combination and positive pressing spring can be for the gas pressure of human body respiration, gas enters the external cooling tank from tube connector, enters air intake duct for human body respiration after cooling.The connected mode of this cooling tank external causes the pipeline path length, dismounting inconvenience, not easy to clean, and air-flow has also caused the increase of expiratory resistance from last storehouse to the flow direction in storehouse down.

Summary of the invention

Long for solving existing storehouse formula positive pressure oxygen respirator pipeline, the problem that respiratory resistance is big, the invention provides a kind of can cooling tank is built-in, breathe the better positive pressure oxygen respirator of comfortableness and breathe the storehouse.

The technical solution adopted in the utility model is: storehouse formula positive pressure oxygen respirator is breathed the storehouse, comprise annular bin, be located at the expiration mouth of pipe on the annular bulkhead, the air-breathing mouth of pipe, the oxygen supply mouth of pipe and annular bin is separated into the dividing plate in Shang Cang and following storehouse from the middle part, have a macropore on the dividing plate, the expiration mouth of pipe is communicated with following storehouse, and the air-breathing mouth of pipe is communicated with last storehouse.

During installation, peace and quiet jar and cooling core are installed in the macropore top of dividing plate, voltage stabilizing membrane combination and positive pressing spring are installed in following storehouse, during use, the gas of breathing out directly enters breathes the bottom, storehouse, forms variable, lower breath pressure with voltage stabilizing membrane combination and positive pressing spring, and gas directly enters peace and quiet jar by macropore, gas after peace and quiet directly enters suction line for human body respiration by the air-breathing mouth of pipe after placing the cooling core cooling of breathing in the storehouse and from the oxygen mix that the oxygen uptake mouth of pipe enters.

This reality has the novel storehouse formula positive pressure oxygen respirator that provides to breathe the storehouse and has following characteristics compared with the prior art: (1) breathes the installing space that is provided with the cooling core in the storehouse, compares with existing external cooling device, has reduced the volume and the pipeline path of respirator.(2) the expiration mouth of pipe and the air-breathing mouth of pipe are located at Xia Cang and the Shang Cang that breathes the storehouse respectively, the gas of breathing out directly enters peace and quiet jar by macropore, compare with the respiratory circulatory system of routine, the path that gas flows into has been carried out changing completely, reduced respiratory resistance, evidence, the comfortableness that the user breathes is better.(3) screw thread mold insert and manufacturability concave station make pipeline setting, be connected and cleaning convenient, quick.
