Abstract
The utility model provides a gas defense dust mask, including face guard (1), aerify gasbag (2), air duct (3), air guide branch pipe (4), outlet duct (5), relief pressure valve (6), filter layer (7), air-blower (8), wherein, the one end and the air-blower (8) of aerifing gasbag (2) are connected, the other end passes through relief pressure valve (6), filter layer (7), air duct (3), air guide branch pipe (4) and face guard (1) are inside to be communicated with each other, outlet duct (5) are opened in face guard (1) lower extreme both sides, a serial communication port, there is heating layer (9) that the one deck periphery was around having the thermal resistance silk between relief pressure valve (5) and filter layer (7. The utility model discloses can effectively gas defense, dustproof can make the people breathe smoothly again.
Description
The utility model relates to a kind of articles for labour protection, particularly a kind of gas defence anti-dust respirator that can be used for the harmful work post of part.
At present, the work of a lot of harmful work posts, as spray paint, surface treatment, welding etc. easily produce a large amount of toxic and harmfuls, operating personnel are caused very big harm, and the result of use of widely used various appliances for labor protection is all undesirable at present, too thin as common fabric mouth mask layer of cloth, pernicious gas is easy to enter; The gas defence anti-dust respirator that some is made with rubber and plastics because it is young to give vent to anger, makes the people of band mouth mask feel to feel oppressed very much.In addition, because winter, air was colder, operating personnel's throat is subject to cold air to stimulate, and is unfavorable for their health.
The purpose of this utility model is to provide a kind of effectively gas defence dustproof, makes the people breathe protective mask smoothly again.
The purpose of this utility model is to realize like this, it comprises face shield, air bag, wireway, air-guide branch pipe, escape pipe, pressure-reducing valve, filter course, air blast, wherein, one end of air bag is connected with air blast, the other end communicates with facepiece interior by pressure-reducing valve, filter course, wireway and air-guide branch pipe, escape pipe is opened in the both sides of face shield lower end, and unique distinction of the present utility model is to have between pressure-reducing valve and the filter course one deck periphery to be wound with the zone of heating of resistance wire.
The course of work of the present utility model is as follows: air blast work is there being the air of pressure to be pressed in the air bag, through the pressure-reducing valve step-down, make air keep certain pressure to enter in the zone of heating and enter wireway by filter course after the heating, and then enter face shield by air-guide branch pipe, make and constantly enter the suitable fresh air of temperature in the face shield, the people breathes the waste gas of back generation and discharges with the escape pipe of face shield lower end, because the air pressure in the face shield will be higher than the external world, so the pernicious gas of outside and dust can not be invaded.
In addition, be more suitable for people's breathing, also can load onto pressure regulator valve respectively, can regulate the air pressure in the face shield at any time at two air-guide branch pipes middle parts in order to make the air pressure in the face shield.
The utility model will be become gentle ozone by the gas that air blast is blown into by decompression, heating, three kinds of means of filtration, therefore both reach gas defence dustproof effect, and the people is breathed swimmingly, not have the sensation of feeling oppressed.
Fig. 1 is shape of the present utility model and structural representation.
Further state below in conjunction with accompanying drawing the utility model is auspicious.
As shown in Figure 1, the utility model comprises face shield (1), air bag (2), wireway (3) air-guide branch pipe (4), escape pipe (5), pressure-reducing valve (6), filter course (7), air blast (8), wherein, one end of air bag (2) is connected with air blast (8), the other end is by pressure-reducing valve (6), filter course (7), wireway (3), air-guide branch pipe (4) communicates with face shield (1) inside, face shield (1) both sides, lower end have escape pipe (5), have one deck periphery to be wound with the zone of heating (9) of resistance wire between pressure-reducing valve (6) and the filter course (7).Pressure regulator valve (10) is equipped with at air-guide branch pipe (4) middle part respectively.
Claims (2)
1, a kind of gas defence anti-dust respirator, comprise face shield (1), air bag (2), wireway (3), air-guide branch pipe (4), escape pipe (5), pressure-reducing valve (6), filter course (7), air blast (8), wherein, one end of air bag (2) is connected with air blast (8), the other end communicates with face shield (1) inside by pressure-reducing valve (6), filter course (7), wireway (3), air-guide branch pipe (4), escape pipe (5) is opened in face shield (1) both sides, lower end, it is characterized in that having one deck periphery to be wound with the zone of heating (9) of hot water radiation wire between pressure-reducing valve (6) and the filter course (7).
2, gas defence anti-dust respirator according to claim 1 is characterized in that in the middle part of the air-guide branch pipe (4) pressure regulator valve (10) being housed respectively.
