Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Embodiment 1:
As shown in Figure 1-2, the positive pole of lithium battery group and circuit 1 thereof is connected on two micro air pump 3 positive terminals after connecting respectively two micro air pump switches 2, lithium battery group and circuit 1 negative pole thereof directly connect respectively on two micro air pump 3 negative terminals, after a Non-return air valve 4 of two micro air pump gas outlet 3 each installations, be connected to the air inlet of filter gas tank 6 at cross gas circuit, the air inlet sidewall of filter gas tank 6 is installed one-way relief valves 5, the gas outlet of filter gas tank 6 connects medical science breathing hose 12 air inlets, medical science breathing hose 12 gas outlets connect the air inlet of air bag 7, the gas outlet of air bag 7 is connected on the hose coupling of air inlet of breathing mask 9, at the face of breathing mask 9, unidirectional air outlet valve 8 is installed again.In order to increase the filter efficiency of air, the air inlet of filter gas tank 6 will have certain space increase and the contact area of filter course, filter course is made up of filtration cotton paper and the activated carbon of solid, in order to prevent that air pump from causing user's anoxic because short of electricity or fault body quit work, one-way relief valves 5 will be used large flow breather cheek valve, ensures user's safety with this.Meanwhile, everyone respiratory airflow per minute is widely different, and from 10 liters/min to 30 liters/min not etc., and people's breathing divides two stages air-breathing and venting one's pent-up feelings, and in expiratory phase, air mass flow being required will be larger.Its flow maximum of existing micro air pump 12 liters/min of left and right, so the two micro air pumps of use of the present utility model add airbag structure simultaneously.As shown in Figure 6, air bag detailed description of the invention: described air bag comprises air outlet adapter 71, air bag rubber layer 72, air bag skin 73, safe tracheae 74, inlet suction port 75, on the sidewall of described safe tracheae 4, pore is set, in the middle of described safe tracheae 4, passage is set.Air-flow enters from inlet suction port 75, air-flow enters safe tracheae 74, the passage that safe tracheae 74 middle parts arrange is very little, cause the pore of mass air flow from the sidewall of safe tracheae 74 air inlets to flow in a large number air bag rubber layer 72, because of the pore on safe tracheae 74 gas outlet sidewalls less than the pore bore of inlet end, cause air-flow constantly to rest in air bag rubber layer 72, thereby inflate to air bag rubber layer 72.User is when air-breathing, and air outlet adapter 71 air pressure reduce, and adds the systolic pressure of air bag rubber layer 72 own, can make the acceleration of air outlet adapter 71 air-flows flow out.Passage in the middle of safe tracheae 74 is to prevent that 72 damages of air bag rubber layer are attached to safe tracheae 74 both sides, cause both sides pore to stop up to cause danger and arrange.This air bag is flat, and capacity is 1 liter of left and right.The present embodiment adopts air bag and enclosed breathing mask as air supply plant, and micro air pump promotes air and directly enters respiratory tract, uses close type breathing mask to ensure air quality under high dust or high haze environment.The present embodiment operation principle: lithium battery group and line powering thereof are to micro air pump, and micro air pump is sent air-flow and entered filter gas tank, is safe intake valve on the entrance sidewall of filter gas tank, and in the time that air pump is not worked because of fault, protection user has air intake.Air-flow is sent into air bag through filtering after entering filter gas tank, and air bag rubber layer stores a part, and another part is sent into breathing mask.When user is air-breathing, breathing mask internal gas pressure reduces can be by the sucking-off of air bag rubber layer storage compartment, and in the time that user feels elated and exultant, the increase of face masks air pressure forces and enters the minimizing of breathing mask air-flow, air bag rubber layer starts stored-gas again, breathes sense difficult problem thereby reduce to reduce.
Embodiment 2:
As shown in Figure 3-4, battery pack and circuit 1 positive pole thereof are connecting on two micro air pump 3 positive terminals after connecting respectively two micro air pump switches 2, lithium battery group and circuit 1 negative pole thereof are directly connected on two micro air pump 3 negative terminals, after a Non-return air valve 4 of two each installations in micro air pump 3 gas outlets, be connected to the air inlet of filter gas tank 6 at cross gas circuit, the air inlet sidewall of filter gas tank 6 is installed one-way relief valves 5, the gas outlet of filter gas tank 6 connects the air inlet of breathing hose 10, the gas outlet of breathing hose 10 connects the air inlet of open nasal tube 11, user's nasal cavity is directly put in the gas outlet of open nasal tube 11.As shown in Figure 5, open concrete connection and embodiment of nasal tube 11: described open nasal tube comprises the inlet suction port 111, connecting hose 112, ear-hang 113, the breathing hose 117 that are connected successively, and the end of described breathing hose 117 arranges nose clip 115 and nasal tube 116.Inlet suction port 111 is connected with connecting hose 112, and connecting hose 112 other ends are directly fixed on ear-hang 113 inside, the lock screw 114 that ear-hang 113 exports be connected with the breathing hose 117 of nose clip 115 and nasal tube 116.Open nasal tube is the face that hangs over user taking ear-hang 113 and nose clip 115 as stress point, and lock screw 114 can regulate the distance between ear-hang 113 and nose clip 115.Nose clip 115 and nasal tube 116 are put into user's nasal cavity, can take user 1/2 to 2/3 nasal cavity, can not stop up nasal cavity completely.The present embodiment adopts open nasal tube as air supply plant, and micro air pump promotes air and directly enters respiratory tract, uses the absorption concentration of PM2.5 in open nasal tube diluent air under the lighter living environment of haze, provides whereby high-quality air for human body respiration.The operation principle of the present embodiment: lithium battery group and line powering thereof are to micro air pump, and micro air pump is sent air-flow and entered filter gas tank, air-flow is sent into breathing hose through filtering after entering filter gas tank, arrives open nasal tube.Nose clip on open nasal tube and nasal tube are directly placed in user's nasal cavity, air-flow directly enters user's nasal cavity, air-flow when user is air-breathing after a large amount of filtration and lacked extraneous air-flow and enter respiratory system simultaneously, has diluted the concentration of PM2.5 in outside air.In the time that user feels elated and exultant, air-flow directly flow into the external world by nasal tube outside.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
