Description

The open mask of unidirectional gas transmission

Technical field

The present invention relates to daily hygiene articles fields, and in particular to the open mask of unidirectional gas transmission.

Background technique

Mask has certain filtration to the air for entering lung, in respiratory infectious disease prevalence, in dirts such as dust In the environment of dye when operation, wear masks with extraordinary protective effect.In outdoor sport, to resist dust storm and cold, or There have to be movable in the environment of air pollution, and putting on has protective effect on mask.It is worn in hospital, construction site, Sand Dust Environment, It can prevent sucking germ, dust.But existing mask all uses air inlet and exhaust passage to share, what is be discharged from respiratory system is useless Mask cannot be discharged in gas in time, sucked repeatedly, to influence the comfort that mask uses, be also unfavorable for human health, and.

Summary of the invention

The object of the present invention is to provide the open mask of unidirectional gas transmission, which will use unidirectional gas transmission route, can will be into Port and exhaust outlet are completely separable, and exhaust outlet is in open state always.

The open mask of unidirectional gas transmission, including mask body, filtering air delivery device, connection filtering air delivery device 2 and impenetrating mouth The appendix of cover, the appendix, which is located at the lower section of nostril, is equipped with tubaeform Window for ventilation, the tubaeform Window for ventilation and mask Intracorporal part appendix vertically communicates, and guarantees the air current flow direction phase of tubaeform Window for ventilation air current flow direction with appendix Vertically, air curtain is formed, the appendix mutually hangs down in the intracorporal air current flow direction of mask and the air current flow direction of Window for ventilation Directly, the end of the appendix is gas vent, and gas vent is in open state always.

The appendix, which is located in mask body, is equipped with distribution of air flow case, and the thickness of the distribution of air flow case is greater than and appendix Bore, the tubaeform Window for ventilation is installed vertically on the inside of distribution of air flow case, and communicates with distributor box.

The filtering air delivery device, including shell, the blower being set in the housing, set on blower two sides and on shell Two air inlets, the filter membrane set on air inlet, the air outlet on shell, the anion hair between blower and air outlet Raw device, set on shell lower end knob switch, be installed on the battery of housing bottom.

Due to being equipped with above structure, which reduces the inspiratory resistance that user is experienced to greatest extent；It secures Air-flow disengaging, the route of flowing and direction, air-flow in appendix one-way flow always, and the position of air-flow into and out of mask is complete Complete different, the exhaust gas of nostril exhalation can be taken out of outside mask by the air-flow in appendix immediately by Window for ventilation, without in mask Inside forms residual gas, guarantees that wearer in any air environment, can enjoy comfortable, healthy breathing.

Specific embodiment

Implement 1

As shown in Figure 1, Figure 2, Figure 3 shows, the open mask of unidirectional gas transmission, including mask body 1, filtering air delivery device 2, connected The appendix 3 of air delivery device 2 and impenetrating mouth cover 1 is filtered, the appendix 3, which is located at the lower section of nostril, is equipped with tubaeform Window for ventilation 4, The tubaeform Window for ventilation is vertical with the part appendix 3 in mask body 1 to be communicated, and guarantees tubaeform Window for ventilation air current flow direction It is perpendicular with the air current flow direction of appendix 3, form air curtain, air current flow direction of the appendix 3 in mask body 1 Perpendicular with the air current flow direction of Window for ventilation 4, the end of the appendix 3 is gas vent 31, and gas vent 31 is in opens always Put state.It filters air delivery device 2 and uses miniature electric blower 22, appendix will be transported to incessantly by the pure air of filtering 3.Air-flow disengaging, the route of flowing and direction, air-flow one-way flow always are secured, traditional mask air-flow sucking has been abandoned and is exhaled The shared design method in channel out.When air-breathing, negative pressure is generated on the inside of Window for ventilation 4, the part pure air in appendix 3 is due to negative Pressure effect, flow direction change, and enter nostril from Window for ventilation 4, clean air is provided to the respiratory system of people.(figure One) when, exhaling, the exhaust gas come out from nostril enters appendix 3 from tubaeform Window for ventilation, by the faster appendix 3 of speed Air-flow is quickly taken away, without remaining in mask, to guarantee that the air sucked when air-breathing next time is that fresh cleaning is empty Gas.(figure two) gas vent 31 is in open state always, and the size and speed of air-flow are inputted by control filtering air delivery device, Guarantee and air pressure herein atmospheric pressure will not occur not to guarantee the air only export but no import at gas vent 31 always >=1.1 Filtered air inversely enters the phenomenon inside mask.The bore of gas vent 4 is greater than the caliber of 3 arbitrary portion of appendix, So that the exhaust gas breathed out from nostril is easier quickly discharge.The preferably air-locked material of mask body, prevents filtered air Into mask.Using electronic filtering air delivery device, traditional mask is reduced to greatest extent, nose suction is leaned on to draw air into mouth entirely The inspiratory dyspnea covered and generated；Importantly, air-flow disengaging, the route of flowing and direction are secured, the air-flow in appendix 3 Always one-way flow, and the position of air-flow into and out of mask is entirely different, the exhaust gas of nostril exhalation can be defeated immediately by Window for ventilation Air-flow in tracheae 3 is taken out of outside mask, without forming residual gas inside mask.Meanwhile the air sucked every time is all It is clean, pure and fresh.To guarantee that wearer in any air environment, can enjoy comfortable, healthy breathing.

Implement 2

As shown in Figure 1 and Figure 2, the appendix 3, which is located in mask body 1, is equipped with distribution of air flow case 32, the distribution of air flow case 32 thickness is greater than the bore with appendix 3, and the tubaeform Window for ventilation 4 is installed vertically on the inside of distribution of air flow case 32, and It is communicated with distributor box 32.

Implement 3

As shown in figure 3, the filtering air delivery device 2, blower 22 including shell 21, in shell 21 is set to blower 22 two sides and two air inlets 23 being located on shell 21, the filter membrane 24 set on air inlet 23, the air outlet on shell 21 27, the anion generator 25 between blower 22 and air outlet 23, the knob switch 26 set on 21 lower end of shell, installation Battery 28 in 21 bottom of shell.
