Two ends are the exhaust pipe formed by screwed pipe 13.
The defect of oxygen atomizer in Fig. 6 is, when expiration, atomization liquid can be together discharged from screwed pipe 13, one
It is to cause to waste, second is that medication is inaccurate, third, pollution air.
Utility model content
In view of the above problems, the utility model be directed to it is a kind of exhale when atomization liquid will not with exhalation other
The oxygen atomizer being discharged in air.
The oxygen atomizer of the utility model comprising：Tank body, liner, connector, conduit, oxygen connecting tube；
Tank body is formed as tubulose, lower end closed, and upper end is covered by top surface, and upper port is formed on the upside of top surface；
Liner is formed in tank body, liner bottom surface be formed as cone, conical tip downward, at conical tip
Be connected to conduit first end, the second end of conduit is connected to the lower end for the oxygen connecting tube being vertically arranged, oxygen connecting tube it is upper
End is connected to source of oxygen；
The upper end of liner is formed with the oblique guide surface of annular, and the upper end diameter of the oblique guide surface of annular is more than lower end diameter；
The plug of truncated cone is connected on the downside of the top surface of tank body by spring；Plug corresponds to the circular slanting of liner upper end
To guide surface；In its natural state, plug is detached with preset distance with the oblique guide surface of annular；
Upper port upper end is connected to the first port of connector, and connector further includes second port, third port；Second port is set
It is equipped with check valve, third port is connected with flexible screwed pipe, and the one end of screwed pipe not connect with connector is provided with mouthpiece.
Preferably, the check valve is made of the tube body that plastic film is formed, in its natural state, tube body not with connector
It fits together on the inside of the two facing walls of the end of connection；When having air-flow outflow, by airflow function, the two of the fitting
Wall separates, and is flowed out for air-flow.
Preferably, the tank body and liner are transparent.
Since the oxygen atomizer of the utility model is provided with plug, when air-breathing, plug is in oxygen and atomization liquid air-flow
Under the action of rise；When expiration, plug declines under the action of exhaled air flow and closes liner, and exhaled gas is from connector as a result,
Second end outflow, avoid atomization liquid escape into air.

Specific implementation mode
In the following, the oxygen atomizer of the utility model is described in detail in conjunction with attached drawing.
The oxygen atomizer of the utility model comprising：Tank body 10, liner 20, connector 12, conduit 22, oxygen connecting tube
23。
Tank body 10 is formed as tubulose, lower end closed, and upper end is covered by top surface, and upper port 11 is formed on the upside of top surface.
Liner 20 is formed in tank body 10, and liner bottom surface 21 is formed as cone, and conical tip is downward, conical
22 first end of conduit is connected at tip, the second end of conduit 22 is connected to the lower end for the oxygen connecting tube 23 being vertically arranged, oxygen
The upper end of gas connecting tube 23 is connected to source of oxygen.
The upper end of liner 20 is formed with the oblique guide surface 24 of annular, and the upper end diameter of annular oblique guide surface 24 is more than lower end
Diameter.
The plug 25 of truncated cone is connected on the downside of the top surface of tank body 10 by spring 26；Plug 25 corresponds to liner upper end
The oblique guide surface of annular 24；In its natural state, plug 25 is detached with preset distance with annular oblique guide surface 24.Plug 25
Be formed as hollow or convex thin plastic sheet under is pressed into.
11 upper end of upper port is connected to the first port of connector 12, and connector 12 further includes second port 13, third port；The
Two-port netwerk is provided with check valve 13, third port is connected with flexible screwed pipe 14, and screwed pipe 14 is not connect with connector
One end is provided with mouthpiece 15.
Check valve 13 can be realized in a variety of forms.A kind of preferred embodiment is given below.
Check valve 13 is made of the tube body that plastic film is formed, in its natural state, as shown in figure 3, tube body not with connect
It fits together on the inside of the two facing walls of the end of head connection, such as the lips of the closure in oral cavity；When having air-flow outflow, such as scheme
It shown in 5, is separated by two walls of airflow function, the fitting, such as the lips after opening mouth, is flowed out for air-flow.This check valve
Often there is application in the anti-back flow of gas of floor drain.Here the oxygen atomizer this check valve converted.
Tank body 10 and liner 20 are transparent, to facilitate the atomization situation of observation liquid.
In use, liquid is poured into tank body 10 first.Specifically, connector 12 is removed, liquid is fallen via upper port 11
Enter tank body 10.
Connector 12 has been reinstalled, screwed pipe 14 is bent so that tank body keeps vertical, patient's mouth mouthpiece 15.It is logical
The bottom for crossing the inside courage of source of oxygen 20 is constantly filled with oxygen.When oxygen passes through liquid, bubble is formed, by part medical liquid atomizing
Disengage it from liquid.
When the patient inhales, check valve 13 is closed, and plug 25 is lifted up under suction, and spring 26 is compressed, plug
Gap between son 25 and the oblique guide surface of annular becomes larger, and atomization liquid outflow enters connector 12 via upper port 11, at this time by
It is closed in check valve 13, all enters patients with respiratory tract via screwed pipe 14 and mouthpiece 15.
As the patient exhales, the gas of exhalation flows into connector 12, when exhaled gas is flowed to tank body 10, the atomization with outflow
The direction of liquid is on the contrary, prevent the outflow of atomization liquid, and plug by the upward pressure of atomization liquid air-flow due to being become at this time
Small, spring 25 can be returned to nature, or even can continue to move downward and completely enclosed liner under the pressure of exhaled gas
20 upper end limits or avoids the outflow of atomization liquid.Exhaled air flow opens check valve 13 simultaneously, and exhaust gas is from 13 row of check valve
Go out.
