Abstract

An isolated toxicity mask can isolate toxicity more drastically and is more conveniently for using. A group of air disinfection filters is allocated and is connected with an air inlet on mask encloser through a duct, a pressure buffering spacer is fixing arranged on the mask encloser, the breath of operator is more naturally while wearing to work, the safety performance is better, and the structure is simple.

Description

Every malicious mask

Technical field

The utility model relates to a kind of breathing mask device, in particular for decorate, that cleaning household and auto repair are used is a kind of every malicious mask.

Background technology

At present, known breathing mask, a kind of fire fighter of being carries the breathing mask with oxygen, a kind of is by the mask of two easy screen packs on the face shield every poison, the former cost is higher, and common operating personnel carries and inconvenience, latter's gas defence effect a little less than, longer as if putting on the working time, the sensation expiratory dyspnea, lung constriction is strong, owing to thoroughly can not smell the dense flavor of poisonous and harmful smell again every poison, and it is not smooth again that face shield invests ventilation heat radiation on the face, and Sweat streamed down one's face for the staff, directly influences operating efficiency and personal security.

The utility model content

Higher in order to overcome existing breathing mask cost, carry inconvenience, not thorough every poison, ventilate and freely do not wait deficiency, the utility model provides a kind of novel air sterillization cleaner to be connected with face shield, thereby addresses the above problem.

The technical scheme that the utility model wants the technical solution problem to be adopted is: acquire a cover air sterillization cleaner on former gas defence mask basis, one air admission hole is set on face shield again to be attached thereto and to connect, at the induction port end one pressure buffer partition is set, be fixedly connected on the face shield, after air enters the air sterillization cleaner by air pressure adjustment valve, filter out airborne moisture content through the water proof device earlier, enter again after malicious device filters, send into through conduit, suck nasal cavity again through the pressure buffer partition, alleviated the air pressure that nose bears, felt more natural, more comfortable.

The beneficial effects of the utility model are, thoroughly are convenient for carrying poisonous and hazardous gas the time in the filtered air, and can alleviate operating personnel's respiratory pressure, increase work efficiency.

Description of drawings

Followingly in conjunction with the accompanying drawings the utility model is further specified

Fig. 1 is the utility model face shield shell front view

Fig. 2 is the utility model air sterillization cleaner structure figure

Fig. 3 is the utility model face shield shell rearview

Fig. 4 is the utility model face shield shell-side view

In Figure of description, (1) face shield shell; (2) fixed band; (3) air admission hole; (4) venthole; (5) air pressure is adjusted valve; (6) air sterillization filter housing (1. water proof device, 2. every malicious device); (7) connector; (8) conduit; (9) pressure buffer partition.

Specific embodiments:

In Fig. 1 and Fig. 2, fixed band (2) is fixed on the face shield shell (1), conduit (8) is connected on air admission hole (3) and the connector (7), the fixedly connected air pressure in air sterillization filter housing (6) two is adjusted valve (5) and connector (7), venthole (4) is arranged at face shield shell (1) middle part suitable location, adapts with venthole (3) and human body face structure.

In Figure of description, when air is adjusted valve (5) and is entered by vapour pressure after, after the water proof device filters out moist moisture content, enter again earlier and filter out harmful poisonous gas every malicious device, through conduit (8) from air admission hole (3), pressure buffer partition (9) is again in the suction body, the waste gas of breathing out is then discharged from venthole (5), moves in circles with this.

Claims

1, a kind of every malicious mask, the face shield shell, conduit, the air sterillization filter housing connects successively, it is characterized in that: the air sterillization filter housing is connected with manhole appendix on the face shield shell by conduit, and the other end is connected with the air pressure regulator valve.

2, according to claim 1 every malicious mask, it is characterized in that water proof device in the air sterillization filter housing, place air sterillization filtering body both sides respectively every malicious device, interconnect.
