Abstract
The utility model relates to a breathing mask, in particular to a simple respiratory protection device. The simple respiratory protection device solves the problem that underground operators cannot ask for help when suffering anoxia asphyxia. The simple respiratory protection device comprises a mask, an inhaling tube, an exhaling tube, an alarm tube and an alarm inflating ball. An inhaling opening communicated with the inside and the outside and an exhaling opening communicated with the inside and the outside are formed in the middle of the mask side by side. The inhaling tube and the exhaling tube are fixed into a whole side by side. A tube opening in the rear end of the inhaling tube is communicated with the inhaling opening, and an inhaling check valve is installed in the tube opening in the rear end of the inhaling tube. An inhaling filter element is installed in a tube opening in the front end of the inhaling tube. A tube opening in the rear end of the exhaling tube is communicated with the exhaling opening, and an exhaling check valve is installed in the tube opening in the rear end of the exhaling tube. The front portion of the alarm tube and the front portion of the exhaling tube are fixed into a whole side by side, and a whistling hole penetrating through the inside and the outside is formed in the front tube wall of the alarm tube. The simple respiratory protection device is suitable for various kinds of underground operation such as desilting operation and dredging operation.
Description
Technical field
The utility model relates to breathing mask, specifically a kind of simple and easy respiratory protection equipment.
Background technology
In daily life, such as, in the time carrying out underground job (dredging operation, dredging operation etc.), operating personnel often needs to enter in person in various underground installations (comprising pipeline, sewer, methane-generating pit, cellar etc.).Because the oxygen content in underground installation is extremely low, in order to prevent anoxia asphyxia, operating personnel conventionally wears breathing mask and enters in underground installation.But in operation process, such as, once breathing mask breaks down (tracheae obstruction, tracheal rupture etc.), just can there is anoxia asphyxia in operating personnel.Once and there is anoxia asphyxia, operating personnel just cannot sounding, causes it to cry for help, and directly jeopardizes thus operating personnel's life security.Based on this, be necessary to invent a kind of brand-new breathing mask, to solve the problem that cannot cry for help when anoxia asphyxia occurs underground job personnel.
Summary of the invention
The utility model, in order to solve the problem that cannot cry for help when anoxia asphyxia occurs underground job personnel, provides a kind of simple and easy respiratory protection equipment.
The utility model is to adopt following technical scheme to realize: simple and easy respiratory protection equipment, comprises face shield, air intake duct, exhaust tube, warning pipe, warning inflatable ball; Wherein, the middle part of face shield offers the inside and outside air entry connecting and the exhalation vents of inside and outside perforation side by side; Air intake duct and exhaust tube are fixed as one side by side; The rear end mouth of pipe of air intake duct is communicated with air entry, and in the rear end mouth of pipe of air intake duct, breather cheek valve is installed; In the front end mouth of pipe of air intake duct, air-breathing filter core is installed; The rear end mouth of pipe of exhaust tube is communicated with exhalation vents, and in the rear end mouth of pipe of exhaust tube, expiratory one-way valve is installed; The front portion of warning pipe and the front portion of exhaust tube are fixed as one side by side, and the anterior tube wall of warning pipe offers the inside and outside hole, the whistle connecting; The rear end mouth of pipe of warning pipe is communicated with warning inflatable ball.
Concrete use procedure is as follows: first, face shield is worn on face by operating personnel, and ensure that air entry and exhalation vents are all communicated with nasal cavity sealed, the rear portion colligation of warning pipe is fixed on clothes simultaneously.Then, operating personnel enters in underground installation, and ensures that the front end mouth of pipe, the front end mouth of pipe of exhaust tube, the warning pipe front end mouth of pipe of air intake duct all stretch out outside underground installation.Carrying out in the process of underground work or dredging operation, in the time that operating personnel is air-breathing, air-breathing produced negative pressure is closed expiratory one-way valve, and breather cheek valve is opened, fresh air outside underground installation first filters via air-breathing filter core, then enters operating personnel's nasal cavity by air intake duct.In the time that operating personnel exhales, the malleation producing of exhaling is closed breather cheek valve, and expiratory one-way valve is opened, and the air that operating personnel breathes out is discharged outside underground installation by exhaust tube.In this process, such as, if air intake duct or exhaust tube break down (tracheae obstruction, tracheal rupture etc.), just operating personnel can cannot sounding because of anoxia asphyxia.Now, operating personnel only need pinch and press warning inflatable ball with hand, and the air in warning inflatable ball is just managed discharge by warning, and makes hole, the whistle send birdie.Personnel outside underground installation can learn that by birdie anoxia asphyxia occurs operating personnel, sues and labours in time to operating personnel thus in time.Based on said process; simple and easy respiratory protection equipment described in the utility model is based on brand new; while making underground job personnel that anoxia asphyxia occur, can cry for help in time by birdie; efficiently solve thus the problem that cannot cry for help when anoxia asphyxia occurs underground job personnel, thereby effectively ensured underground job personnel's life security.
The utility model is rational in infrastructure, it is ingenious to design, and efficiently solves the problem that cannot cry for help when anoxia asphyxia occurs underground job personnel, is applicable to various underground jobs (such as dredging operation, dredging operation etc.).
