Description
Technical field
The invention belongs to half face shield type individual dust-proof breath mask technical field, what relate generally to is a kind of breathing follow-type electric air-supplying breathing mask.
Background technology
The personal breathing face shield mainly uses in places such as the tunnel that larger dust, smog are often arranged, workshops, is used for the protection to the personal breathing system.The personal breathing face shield generally is comprised of following components: mask body, air cleaner, air guided valve.Mask body is mainly used in consisting of an airtight good space between consisting of between face shield and the user's mouth and nose, enters mouth and nose to prevent the hazardous mediums such as dust; Air cleaner is unique passage that air enters face shield, has the function of dust removal by filtration; Air guided valve is mainly used in the user is sucked and Exhaled gasesS transmits along separate routes.Traditional personal breathing face shield mostly is self-priming structure, in use namely, when the user sucks gas, becomes negative pressure in the face shield, and the inside airtight valve of air guided valve is opened, and is entered in the face shield through air cleaner by extraneous air and breathes for the user; During breath, become malleation in the face shield, the inside airtight valve of control directional valve is closed, and outside airtight valve is opened, and Exhaled gasesS is discharged by the exhaust outlet on the mask body.Because stopping of the high-absorption material of air cleaner, the sense of feeling oppressed that will occur breathing with difficulty when the user uses for a long time is when respiratory rate is higher even the generation sensation of asphyxia.The larger problem of expiratory resistance when breathing for solving self-priming breathing mask, the mode of passing through the lasting air-supply of increase blower that adopts has at present played certain effect really, yet the air-supply that continues can allow the user that the sensation of filling with wind is arranged, the long-time meeting of use is exhaled not smooth, when reducing inspiratory resistance, but increased accordingly expiratory resistance.Although part full facepiece mask product is also arranged by the dirt box is placed on the oronasal mask outside or waist solves the expiratory resistance problem with filtering with blower, will certainly affect the visual field and wear air-tightness yet blower is placed on the oronasal mask outside with filter dirt box; Be placed on waist and since blower from oral area away from the air output loss large, require the blower fan air output to want large, corresponding blower sizes is just bigger than normal, product is relatively heavier, and blower and filter dirt box are hung over waist, and what can be on to some extent impact of work.
In addition, existing oronasal mask adopts rubber compacting (injection) moulding or rubber-plastics material injection moulding more, and security reliability has certain limitation during use.And filter dirt box is to adopt screw thread or rotary extrusion type spinning structure with being connected of oronasal mask, and it is very not too convenient to change.
Summary of the invention
Purpose of the present invention produces thus, proposes a kind of breathing follow-type electric air-supplying breathing mask.Solved existing dust-proof breath mask and breathed uncomfortable problem, improved comfortableness and security reliability that breathing mask uses, reduced the volume of product, made the simple in structure of product, the replacing of filter dirt box is convenient and swift.
The present invention realizes that the technical scheme that above-mentioned purpose is taked is: a kind of breathing follow-type electric air-supplying breathing mask, comprise filter dirt box, oronasal mask, head fixation kit, outlet valve assembly, blower assembly, described oronasal mask comprises cover body part, support housing part and oral area coupling assembling, support housing partly is connected to the center of cover body, the oral area coupling assembling is arranged on the support housing part, also is provided with suction hole on oronasal mask; Described outlet valve assembly is arranged in the support housing part of oronasal mask, mainly by top cover, base, photoelectric sensor, control sensing circuit plate and breathe directed valve block and form, top cover is fixed on the base, has exhaling hole on the top cover, breathe directed valve block and be connected with top cover, photoelectric sensor and control sensing circuit plate all are arranged in the base; The blower assembly is arranged in the support housing part of oronasal mask, and between outlet valve assembly and oronasal mask, the motor output line of blower assembly is connected with photoelectric sensor on the outlet valve assembly.
Therefore the present invention can detect in real time user's respiratory movement and control the motor automatic ventilating owing to be provided with the outlet valve assembly at existing breathing mask, and automatic control fan rotates air-supply when air-breathing, and controls stopping fan rotation when exhaling.Overcome existing breathing mask after setting up blower, the sensation of filling with wind has been arranged, worn for a long time use and have the smooth phenomenon of expiration.Adopt elastomeric material to make owing to breathe directed valve block, have certain elasticity, therefore can move back and forth according to user's respiratory movement, when air-breathing, directed valve block is closed, and photoelectric sensor is connected circuit, and the powered supplied air device starts air-supply; During expiration, directed valve block is opened, and photoelectric sensor makes circuit is disconnected, and the powered supplied air device is out-of-blast, make Exhaled gasesS pass through outlet valve and discharge smoothly outside the mouth mask, without any expiratory resistance, improved comfortableness and security reliability that the wearer uses.
Because oronasal mask is combining structure, the cover body position that contacts with the human body mouth and nose adopts soft elastomeric material to make, fit with the human face better, so that when guaranteeing products air tightness, wearing more comfortable.Support housing partly adopts the plastic or other material system with certain degree of hardness, has both guaranteed the peaceful reliability worn can make again the blower assembly mounted thereto.
Because the blower assembly is installed on the oronasal mask, overcome external blower volume large, use inconvenience, affect the problem such as the visual field.It is fast that the high-speed micro motor has rotating speed, and air quantity is large, low noise advantages, novel structure, and easy to use, it is little to meet volume, lightweight requirement.
Because the joint of filter dirt box and the connecting portion of oronasal mask are provided with retaining mechanism, when loading, unloading filter dirt box, as long as just filter dirt box can be fastened on the oronasal mask with the hand propelled adjusting head, so that the loading and unloading of filter dirt box are not only convenient but also safe and reliable.
