Specific embodiment
With reference to embodiment, technical solution of the present invention is described in further detail, but do not constituted pair
Any restrictions of the invention.
In order to which more clearly the present invention will be described, embodiment is listed below to illustrate superiority of the invention.
Embodiment 1
As shown in Figure 1, a kind of gas-water separation mechanism of ventilator return, including shell 1, set on the shell 1
The proximal end pipeline 3 for having the distal line 2 for being connected with equipment and being connected with for human body；
The shell 1 is equipped with water storage cavity 4 close to the position of proximal end pipeline 3；
The gas for importing distal line 2, which is equipped with, close to the position of distal line 2 in the shell 1 carries out air water
Isolated moisture trap 5；
It is equipped with close to the position of proximal end pipeline 3 for the water water conservancy diversion that moisture trap 5 is isolated in the shell 1
To the air deflector 6 of water storage cavity 4；
Enter the channel 9 of proximal end pipeline 3 between the moisture trap 5 and air deflector 6 for supplied gas.
In practical process, shell 1 is that the direction of proximally pipeline 3 is inclined, and moisture trap 5 can choose a variety of shapes
The structure of formula, the principle of moisture trap 5 are to allow the microlayer model in gas at this by a face and the contact of aqueous gas
It carries out gathering on face collecting as biggish drop.
In order to preferably be condensed microlayer model, in general, we can select the face containing certain tilt angle, should
Face can change gas flow direction, make in gas that the liquid in malleable direction does not agglomerate on the face.
It is a variety of that air deflector 6, which can choose, for example, connect on moisture trap 5 it is some can water conservancy diversion channel 9, Huo Zheneng
Guide surface etc. is set on enough paths left in the water of moisture trap 5.
Thick date core shaped or spinning taper between the preferably both ends detail of shell 1.
In the following, showing the core of the design with two different ways of realization to better illustrate this programme.
Concrete scheme 1:
Based on above-mentioned design, in the present solution, the moisture trap 5 is bullet, the moisture trap 5
Taper end towards distal line 2.The inside of bullet can be emptied, and certainly, not repel it for solid cone shape body.
The surface of the bullet is inclined surface, and there are two effects, and one is the direction for changing gas flowing, is convenient for micro- liquid
Drop cohesion；One is to arrive gas flow guiding if cannot all be agglomerated by part microlayer model on bullet surface in gas
The inner wall of shell 1 allows the inner wall of gas and shell 1 to contact, and remaining drop can be agglomerated in 1 inner wall of shell.
And as an improvement, the air deflector 6 is a gradually thick hollow pipeline, the taper end of the air deflector 6 with
Proximal end pipeline 3 is connected to；The butt end of the air deflector 6 is opposite with the butt end of moisture trap 5；The butt end of the air deflector 6
Diameter is equal to the butt end of moisture trap 5；Fig. 1 can specifically be referred to；
In the embodiment of figure 1, it is preferable that the butt end edge of the air deflector 6 is equipped with a turned-out flange 7；
The flange 7 is most preferably that section is arc, which is cyclic annular cambered surface.
Since the butt diameter of air deflector 6 is equal to the butt end of moisture trap 5, drop is thick from moisture trap 5
End leave after can be contacted with flange 7, flange 7 can by drop water conservancy diversion into water storage cavity 4 or water conservancy diversion to the surface of air deflector 6 in turn
It reaches in water storage cavity 4.Meanwhile flange 7 can prevent the gas in shell 1 that the liquid on 6 surface of air deflector is brought into air deflector 6
Hollow portion in.
And more preferably improved as one kind, the air deflector 6 is a gradually thick hollow pipeline, the air deflector
6 taper end is connected to proximal end pipeline 3；The butt end of the air deflector 6 is opposite with the butt end of moisture trap 5；The water conservancy diversion
The butt diameter of device 6 is less than the butt end of moisture trap 5；It is more favorable for drop in this way and reaches air deflector 6 under gas drive
Surface.Specific visible Fig. 2.
In Fig. 2, the butt end of air deflector 6 extends to the inside of moisture trap 5, in actual design process, air deflector 6
Butt end can also not extend to the inside of steam-water separator, for its using effect, the design of Fig. 2 is relatively reliable.
Such as Fig. 2, in this is preferably improved, the butt end edge of the air deflector 6 is again provided with a turned-out flange
7.The flange 7 is similarly cyclic annular cambered surface.
But the effect for the flange 7 of flange 7 acted in Fig. 1 is different in Fig. 2, and the flange 7 of Fig. 2 mainly hinders
Only the liquid on 6 surface of air deflector is brought into the hollow portion of air deflector 6 by the gas in shell 1.
Concrete scheme 2
It is described in the present solution, be equipped with the hollow nucleome 8 of jujube core shape in the shell 1 based on above-mentioned design
Nucleome 8 is steam-water separator close to the surface of distal line 2；The nucleome 8 is air deflector 6 close to the surface of proximal end pipeline 3；
The nucleome 8 is connected to close to the end of proximal end pipeline 3 with proximal end pipeline 3；The center of nucleome 8, institute is arranged in the channel 9
The outer surface for the nucleome 8 stated is equipped with the drip ring 10 being connected to channel 9.
Specific visible Fig. 3, in this concrete scheme, channel 9 is circular channel 9, and the quantity and diameter in channel 9 are according to ventilation
Depending on amount, in order to reduce air resistance, in general, the gross area of circular channel 9 should be controlled larger to allow gas to
Enough smooth circulations.In the present embodiment, circular channel 9 is set as 4.In the fabrication process, channel 9 may be arranged as other
In general shape is all feasible.
Its principle is that first in the surface flow of the close distal line 2 of nucleome 8, gas can change air-water mixture
Direction, liquid can be gathered in the surface of nucleome 8, and then gas enters nucleome 8 from channel 9 and then enters proximal end pipeline 3；Due to having
The presence of drip ring 10, under normal circumstances, water will not enter in channel 9.The water of cohesion can be flowed along nucleome 8, reach core
Then the other end of body 8 is collected and is entered in water storage cavity 4.
For more preferably angle, one or more diversion trench can be opened up on the surface of nucleome 8, diversion trench is along core
The major diameter direction of body 8 extends from one end of nucleome 8 to other end, is more conducive to collecting for drop in this way.
Risk inside nucleome 8, the drip ring 10 are entered in order to preferably reduce water from the end of drip ring 10
Free end be equipped with water fender 11, the water fender 11 is annular, the end of the inner ring of the water fender 11 and drip ring 10
Portion's connection.Drop or liquid film would not enter the inside of nucleome 8 in this way.
As further preferred, in concrete scheme 1 and concrete scheme 2, can by shell 1 be at least partially arranged to for
Semiconductor chilling plate, inner wall of the cold end of semiconductor chilling plate as shell 1, outer wall of the hot end as shell 1.This preferably sets
In meter, semiconductor chilling plate can be arranged in shell 1 close to one end of distal line 2, the gaseous state in gas can be improved in this way
The cohesion of water.
Above-described is only presently preferred embodiments of the present invention, all made within the scope of the spirit and principles in the present invention
What modifications, equivalent substitutions and improvements etc., should all be included in the protection scope of the present invention.
