Portable respiration device

Abstract

The invention discloses a portable respiration device. It comprises air tank (10), pressure valve component (20), and regulating valve parts (30); the air introduced from pressure valve component is changed into breathing pressure and the changed air is regularly provided to mouth (31); it also comprises pressure switching parts (40), through which the air is condensed and turn on or off power, and the condensed air is introduced from pressure valve part and by passed; and a vibrating device (50), which can contact with human body, and vibrates when power of pressure switch part is turned on, and then warns condensed air shortage. The invention can reduce human injury and death, it will remind operator the time in time when it is time to add air tank or in dangerous time or place such as diving or in fire, which makes operator call for help from other people.

Description

technical field [0001] The present invention relates to portable breathing apparatus, and more particularly to a portable breathing apparatus that automatically Or manually notify the lack of air. Background technique [0002] Typically, a portable breathing apparatus is a safety device that allows divers underwater or firefighters in a fire to carry a portable breathing apparatus and breathe safely in places where breathing is not normally possible. [0003] Generally, a conventional portable breathing apparatus includes: a portable air tank 10 , a pressure valve part 20 , a regulating valve part 3 and an alarm generator 40 . That is, the portable air box 10 is mounted, and can be carried on the back using a typical portable device 11, so that the air box 10 can be carried at about 200-300 kg / cm 3 Inflate under the pressure, and use this volume of air for about 50 minutes. [0004] In addition, the pressure valve part 20, a three-way valve, makes more than about 60kg / cm ...

AI Technical Summary

Problems solved by technology

[0008] However, alarms using sounds like the above are less effective underwater or at the scene of a fire

[0009] Even the operator himself cannot predict the amount of compressed air and the situation of deterioration under the pressure state because the ambient noise and the tense alarm sound cannot be heard.

In addition, in the case of several people using it at the same time, the alarm sounds everywhere, so it is impossible to detect whose alarm sound is alarming, and when diving, the diver has to check his own residual pressure with a residual pressure measuring instrument, it's very inconvenient

[0010] In particular, in case the operator fails to hear the siren sound at the emergency site or just misses checking the residual pressure by the residual pressure measuring instrument, it may cause serious problems such as casualties
