Specific embodiment
The most critical design of the present invention is: controlling the flow direction of air by intake valve and air outlet valve, pass through air pump
The flowing for controlling air, to realize the inflation of product, air suction function.
For the feasibility for being discussed further present inventive concept, in conjunction with technology contents of the invention, construction feature, realized mesh
And effect, embodiment and attached drawing is cooperated to be explained in detail.
Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of filling gas dual-purpose apparatus, including gas nozzle 1, the gas nozzle is please referred to be provided with
Air inlet 101, gas outlet 105 and cavity 103；Control air is equipped between the cavity 103 and the air inlet 101 from air inlet
Mouthfuls 101 unidirectionally flow into the intake valves 102 of cavitys 103, be equipped between the cavity 103 and the gas outlet 105 control air from
Cavity 103 unidirectionally flows to the air outlet valve 104 of gas outlet 105；The cavity 103 is connected with air flowing in control cavity 103
Air pump 2.Air inlet 101 and gas outlet 105 are respectively set on gas nozzle 1, since intake valve 102 and air outlet valve 104 control air-flow
One-way flow, when the activity of air pump 2, air can only from air inlet 101 into, go out from gas outlet 105.If in use, needing air-breathing
Gas nozzle to air-breathing product is connected on air inlet 101 by function, and the interior gas to air-breathing product, which is sucked out, to be drained into atmosphere；If
Need aerification function, the gas nozzle to inflating articles be connected on gas outlet 105, air then from air inlet 101 by air pump 2 be pumped into
Inside inflating articles.It does not need to store and formed high pressure gas in advance in use, in the device of the invention, it is true not to need setting yet
Sky pump, is but able to achieve inflation and air suction function.
Further, further include for drive air pump work motor 3.Air pump 2 is continuously by motor 3, and power is provided,
Make air pump 2 that air persistently be driven to flow, realizes continuous charge or air suction function.
Further, the gear of linkage is equipped between the air pump 2 and the motor 3.Motor 3 is passed power by gear

Air valve 102 and air outlet valve 104 are alternately opened, and pressure sensor waits for inflating articles/to air-breathing product when can measure inflation/air-breathing indirectly
Real-time air pressure.Once pressure value of the pressure beyond setting, triggering PCB controller 11 forms control signal and disconnects motor 3
Power supply, so that intelligence inflation or air-breathing are realized, without worrying that not enough or after air-breathing the inadequate situation of vacuum degree goes out inner gas pressure
It is existing, and independently observed without user and judge whether air-breathing or inflation reach anticipated demand.The inflation that apparatus of the present invention are able to achieve
Pressure limit is 0.2-10.3bar, and vacuum degree reaches -60KPa.The first aperture 106 and second orifice are offered on cavity 103
107, cavity 103 is connected to by the first aperture 106 with the pump housing of air pump 2, and the pressure sensor is connect at second orifice 107.
It further, further include the battery pack 9 being connect respectively with the motor 3, the PCB controller 11.The battery pack 9
It can be dry cell batteries, or rechargeable battery set, when use are not required for providing AC power source, and being convenient for carrying to open air makes
With.
Further, the intake valve 102 and the air outlet valve 104 are check valve.Intake valve 102 as check valve
With air outlet valve 104, control air-flow one-way flow can be realized.
Further, the air inlet 102 is identical as the size of the gas outlet 104.Air inlet 102 and gas outlet 104
It is equipped with helicitic texture, the hand of spiral of helicitic texture can be identical, be also possible to opposite, it is therefore intended that facilitate external
Same root has the tracheae of helicitic texture, facilitates the power and energy of air-breathing and inflation.
It further, further include radiator fan 8, switch 12, indicator light 15, internal stent 13 and shell 14；The heat dissipation
Fan 8 is fixed on one end of 3 transmission shaft of motor；The indicator light 15, the switch 12 with the PCB controller 11
It connects and exposes to the shell 14；The air inlet 101 exposes to the same side of the shell 14 with the gas outlet 105
On；The gas nozzle 1, the air pump 2, the gear, the motor 3, the PCB controller 11, the battery pack 9 are each attached to
In the internal stent 13.Pass through internal stent 13, gas nozzle 1, air pump 2, gear, motor 3, radiator fan 8, PCB controller 11

Obtain small and exquisite, easy to carry and storage.Air inlet 101 and gas outlet 105 expose on the same side of shell 14, so that product knot
Structure is more compact.It is equipped with sealing ring between the pump housing and connecting rod, at the intake valve 102 and air outlet valve 104 of gas nozzle 1, guarantees inflating
Or gas leak phenomenon will not occur when air-breathing.Damping is equipped at the air inlet 101 of gas nozzle 1 and gas outlet 105 and on motor 3
Pad reduces product noise.Stomata is additionally provided on shell 14, radiator fan 8 is located in wind scooper 10 so that product have it is good
Heat dissipation effect extends life of product.
In conclusion a kind of filling gas dual-purpose apparatus provided by the invention, is respectively set air inlet and outlet on gas nozzle
Mouthful, due to as check valve intake valve and air outlet valve control air-flow one-way flow, when air pump activity, air can only be from air inlet
Into, go out from gas outlet.Motor imparts power to air pump by gear, bearing, persistently mentions the power of motor to make to realize
Air pump is supplied, air pump is made persistently to do eccentric reciprocating motion, continuous charge or air-breathing function are realized in air flowing in driving chamber body
Energy.Pressure sensor triggering PCB controller forms control signal and disconnects the power supply of motor, to realize intelligence inflation or inhale
Gas is sentenced without worrying that not enough or after air-breathing the inadequate situation of vacuum degree inner gas pressure occurs, and not having to user independently to observe
Whether disconnected air-breathing or inflation reach anticipated demand.Built-in battery pack, which meets, is not required for connection AC power source when using, convenient
It is carried to outdoor use.If the gas nozzle to air-breathing product is connected on air inlet, in use, needing air suction function to air-breathing product
Interior gas be sucked out and drain into atmosphere；If needing aerification function, the gas nozzle to inflating articles is connected on gas outlet, air
Then it is pumped into from air inlet by air pump to inside inflating articles.It does not need to store simultaneously shape in advance in use, in the device of the invention
At high pressure gas, setting vacuum pump is not needed, inflation and air suction function are but able to achieve yet.Since the present invention program structure is simple,
Required component can be made small and exquisite, for convenience of carrying, can be made into hand-held product.
Herein first, second ... only represents the differentiation of its title, not representing their significance level and position has what
It is different.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
