The specific embodiment
Come some embodiments of the present invention are elaborated below with reference to Fig. 1～Figure 10.Need to prove that technical scope of the present invention is not subjected to the qualification of these embodiment.
As shown in Fig. 1～5, being provided with oxygen enriching devices on the inside of apparatus for oxygen enrichment of air body 1 (below abbreviate " body 1 " as) is oxygen enriching membrane module 35, this oxygen enriching membrane module 35 is used to improve by getter device 26 described later and is drawn into airborne oxygen concentration in the body 1, generates oxygen-enriched air.Air is after passing oxygen enriching membrane module 35, and its airborne oxygen concentration improves about 30% (nitrogen accounts for 70%) from passing preceding common concentration 21% (nitrogen accounts for 79%).
In addition, also be provided with getter device 26 in the inside of body 1, this getter device 26 is drawn into exogenous QI in the described body 1 from the air entry 3 on the back side that is located at body 1, and sends in the oxygen enriching membrane module 35.The air that does not pass the oxygen enriching film (not shown) in the oxygen enriching membrane module 35 then is discharged to the outside from the air vent 4 at the back side that is located at body 1.
5 for constituting the vacuum pump of suction device, be provided with the air entry (not shown) that the downstream by pipeline 5a and oxygen enriching membrane module 35 connects and is communicated with in the vacuum pump 5, make to be drawn into body 1 interior part air and to pass oxygen enriching film in the oxygen enriching membrane module 35.In addition, the air vent (not shown) of vacuum pump 5 links with the air supply opening 6 that is arranged on the end face of body 1 by pipeline 6a, with the air behind the oxygen enrichment deliver to described air supply opening 6 joining oxygen-enriched air dischargers 7 in.Operate under the control device (not shown) control in being located at body 1, that constitute by circuit board 10 of described vacuum pump 5 and described getter device 26.
Described oxygen-enriched air discharger 7 oxygen-enriched air through flexible pipe 12 and the annular seal space 13 that is used to store dew deliver to user's mouth (not shown) from the parts 9 of supplying gas.The parts 9 of supplying gas are arranged in the mode that can tilt freely, rotate to be worn on the apparatus 8, wears ear, cervical region, a first-class place that apparatus 8 can hang over the user, makes the parts 9 of supplying gas be easy to realize the location in user's mouth.
The characteristics of present embodiment are, vacuum pump 5 adopts be volume little, in light weight and can access big flow wave piston type single head vacuum pump.The locate mode of this vacuum pump 5 is, fixing the location-plate 30 shown in Fig. 8 on the bottom surface of vacuum pump 5, and is provided with rubber-like spring members 31,32 between the base plate 2 of the bottom surface that constitutes body housing 42 and described location-plate 30.In addition, be located near the spring members 32 of piston one side in the vacuum pump 5 and be located at away from the spring constant of the spring members 31 of a side of piston different.
The operational circumstances in the apparatus for oxygen enrichment of air with above-mentioned formation and the effect of generation are described below.
Since vacuum pump 5 uses as described above be have that single head constructs wave the piston type vacuum pump, though have the advantage that volume is little, in light weight and flow is big, vibrate very big.Particularly, wherein adopted single head structure as shown in Figure 3, promptly, an axle side of 41 that is located at the motor 40 of vacuum pump 5 inside links with the piston rod 34 that shakes on above-below direction, shake on above-below direction by piston rod 34, make in the cylinder 33 constantly to attract/bleeding.
Therefore, when piston rod 34 shook, near the vibration the piston will inevitably increase, and was conversely, then smaller away from the vibration of piston one side.Be delivered on the body 1 for the vibration that makes vacuum pump 5 is unlikely, adopt usually to make its localized method by elastomeric material.But, with above-mentioned have a single head structure wave piston type vacuum pump 5 in addition under the localized occasion, if a side of close piston is supported with the identical spring members of spring constant with the side away from piston, can not well vibration be suppressed.For this reason, in the present embodiment, near the spring members 32 of piston one side be configured to different away from the spring constant of the spring members 31 of piston one side.Particularly, bigger in vibration, near a side of piston, be provided with the bigger spring members of spring constant 32, and vibration less, away from a side of piston, be provided with the less spring members of spring constant 31.Like this,, can further reduce the vibration of sending, thereby a kind of apparatus for oxygen enrichment of air of low vibration is provided from vacuum pump 5 by the spring constant of selecting respectively to be complementary with concrete condition.
In addition, though having mentioned the location that relies on spring members 31,32 to carry out in the superincumbent explanation is to be undertaken by the bottom surface of vacuum pump 5, but, can not realize the location by the bottom surface of vacuum pump 5 yet, but as shown in Fig. 6,7, with vacuum pump 5 use spring constants different, be suspended on the body housing 42 of body 1 inside near the spring members 32 of piston one side with away from the spring members 31 of piston one side, located by such state.Like this, come, can further reduce to be delivered to the vibration on the body 1, thereby provide a kind of vibration littler apparatus for oxygen enrichment of air compared with the mode that the bottom surface by vacuum pump 5 positions.
In addition, remain under the occasion of the state of suspending by spring members 31,32 at the vacuum pump shown in Fig. 6,75, even if body 1 overturning, the probability that spring material 31,32 comes off is also little, and under the occasion that is supported by spring members 31,32 in the bottom surface of the vacuum pump shown in Fig. 3,45, the probability that spring members 31,32 comes off is just bigger.Solution to this problem is, as shown in Figure 8, location-plate fixing hole 37 and base plate fixing hole 38 are being set respectively on location-plate 30 and the base plate 2, and in described location-plate fixing hole 37 and base plate fixing hole 38, are inserting the rubber components of making by soft materials such as rubber 36.Like this, even at body 1 suddenly under the occasion of overturning, the position skew between location-plate 30 and the base plate 2 also can be limited by rubber components 36, thereby can prevent that spring members 31,32 from coming off.
But, adopt above-mentioned solution, still exist by rubber components 36 and be delivered to the problem that the vibration vibration big, body 1 on the spring members 31,32 is risen to some extent.In order to address this problem, as shown in Figure 9, the diameter of the base plate fixing hole 38 on the base plate 2 is configured to the diameter (as reserving gap A) greater than rubber components 36.Like this, when body 1 normally was placed on the face that is provided with that roughly is level etc., rubber components 36 did not come in contact with base plate 2, can suppress to be communicated to the vibration on the body 1.Only when body 1 tilts angle more than the setting all around or under the occasion of overturning, rubber components 36 just comes in contact with base plate 2, thereby can prevent that spring members 31,32 from coming off when body overturning etc.
In addition, in order further to reduce the vibration that is delivered on the body 1, as shown in Figure 10, or/and on the connection part between air vent (not shown) and pipeline 5a, the 6a, is that telescopic tube road 39 carry out pipe arrangement connect by the parts that are made of telescopic soft material in the air entry (not shown) of vacuum pump 5.Like this, can alleviate the generation of transfer of vibration that vacuum pump 5 the takes place situation to the body 1.
In addition, the above-mentioned parts that are made of soft material not only can be arranged on suction, air vent and the pipeline 5a of vacuum pump 5, on the connection part between the 6a, also can be arranged on pipeline 5a, 6a midway.
In sum, apparatus for oxygen enrichment of air of the present invention not only volume little, in light weight and stream Amount is big, and vibration is very low, and noise is also very little, so can be widely used in special Need in the special-purpose apparatus for oxygen enrichment of air such as low vibration, low noise hospital, bedroom.
