In addition to providing a safer gas supply device, it is possible to improve the health of the user, and it is possible to eliminate the trouble of having to adjust the equipment at any time by setting the gas supply amount according to the stage. Have.

  In FIG. 1, a gas supply device 10 for sucking oxygen includes a container S as an oxygen supply source in which oxygen gas is compressed and stored as a gas, and is screwed into the container S by a screwing type so as to reduce the discharge amount of the compressed oxygen gas. It comprises a gas discharge amount control valve 100 for controlling to a set value. As the container S, a high-pressure container having excellent durability is used.

  2 to 4, the gas discharge amount control valve 100 is formed such that one side penetrates in the longitudinal direction so as to communicate with the movable valve member 150, and the other side is a central portion of the closing member 110 fastened and fixed to the container S. A flow passage 101 communicating with the discharge port 111 formed in the through-hole, and supported in the flow passage 101 so as to receive the elastic force of the first spring 121 in the upper direction of the discharge port 111. A plunger 130 that is airtightly connected to the flow passage 101 so as to be slidable in the longitudinal direction, and a second spring that is slidable in the longitudinal direction in the flow passage 101 above the plunger 130. 123, a movable block member 140 urged in the direction of the container S, a handle 151 penetrating an opening 141a formed in a central portion of the movable block member 140, and the handle 15 A movable valve member 150 having a valve body 155 provided at an end of the valve body 155, a valve seat 153 attached to the valve body 155 so as to surround and close a bottom surface of the opening 141a, and the movable valve member 150 A pressurizing button member 160 having an insertion port 160a that supports the other side of the third spring 125 supported at one end and is inserted and fixed to the movable valve member 150 with a handle 151 protruding upward. Contains.

  A ring-shaped sealing member 141 is fixed to the bottom surface of the movable block member 140.

  Further, a receiving portion 145 of a third spring 125 is provided around the opening 141a at the center of the movable block member 140 and is concentrically depressed downward with the opening 141a. On the larger concentric circle, a receiving portion 143 of the second spring 123 for supporting the second spring 123 is recessed in a partially depressed shape together with the receiving portion 145 of the third spring 125. .

  In addition, a space room 131 having a shape whose upper side is expanded is formed in the upper portion of the plunger 130.

  Further, the discharge port 111 formed in the central portion of the closing member 110 has a protruding nozzle shape, and the plunger 130 has a recess 133 that is large enough to accommodate the nozzle-shaped protruding discharge port 111. Is provided at the bottom.

  Further, a cup-shaped lid 11 having a boss portion 11 a connected to the exhaust port 105 is coupled to the upper portion of the main body of the gas discharge amount control valve 100.

  On the other hand, reference numeral 133a is a sealing portion that is formed to hermetically close the hole, reference numeral O is a sealing O-ring for maintaining airtightness, and reference numeral 135 communicates with the space room 131 of the plunger 130. In this way, the communication port is formed through the plunger 130, the reference numeral 165 supports the plunger 130, the lower part is a joined body screwed with the closing member 110, and the reference numeral 170 is the main body and the joined body 165. , And a cover body for performing a lower cover function of the gas discharge amount control valve 100. Reference numeral 180 is coupled to the upper portion of the cover body 170 via a locking tool 171 and extends in the longitudinal direction of the pressure button member 160. It is an upper guide member in which a locking projection 181 is formed on the side surface so as to guide the movement.

  Next, the operation of the gas supplier according to the present invention will be described. First, as shown in FIGS. 5 and 6, the lid 11 is removed from the gas discharge amount control valve 100. Next, as shown in FIG. 7A, the boss 11 a of the lid 11 is fitted into the cover body 170 and connected to the exhaust port 105.

  When the pressure button member 160 is moved by a predetermined depth (for example, “H”) with the lid 11 placed on the mouth, as shown in FIG. 7B, the pressure button member 160 is coupled. The moved movable valve member 150 is moved downward by “H”. In conjunction with the movement of the movable valve member 150, the valve body 155 and the valve seat 153 of the movable valve member 150 open the opening 141a of the movable block member 140.

  At this time, since the first spring 121 is elastically urged upward in the space room 131 above the plunger 130, it penetrates in a direction perpendicular to the longitudinal direction of the plunger 130. The oxygen gas from the inside of the container S is filled through the connected communication port 135.

  Further, when the valve seat 153 of the movable valve member 150 moves to the opening 141a side of the flow passage 101 and the pressing button member 160 is moved slightly upward so that the opening degree of the opening 141a is reduced, Since the upper portion of the plunger 130 has a larger cross-sectional performance than the lower portion, the plunger 130 moves downward to close the discharge port 111 of the closing member 110.

  Accordingly, when the pressurizing button member 160 is slightly pressed, the exhaust amount exhausted through the exhaust port 105 formed in the movable valve member 150 and the lid 11 connected to the exhaust port 105 is reduced. The jar 130 moves downward. On the other hand, when the pressurizing button member 160 is strongly press-fitted and the exhaust amount through the exhaust port 105 increases, the secondary plunger 130 moves upward and the discharge amount from the discharge port 111 of the closing member 110 is increased. In association with this increase, the exhaust amount through the exhaust port 105 is also increased. Therefore, the oxygen gas exhaust amount is automatically controlled according to the press-fitting amount of the pressurizing button member 160.

  On the other hand, abnormal pressure such as the presence of strong pressure in the flow passage 101 or the occurrence of a time interval on the movement of the movable valve member 150 and the plunger 130 causes abnormal high pressure. Although it may occur in the upper part, in this case, the movable block member 140 is floated while surpassing the elastic supporting force of the second spring 123 supporting the movable block member 140. .

  Accordingly, a state in which the valve body 155 and the valve seat 153 of the movable valve member 150 open the opening 141a of the flow passage 101 by the upward movement of the movable block member 140 is achieved. Therefore, the abnormal high pressure phenomenon at the upper part of the plunger 130 is eliminated, and the safety is further improved.

  Further, by providing a receiving portion 143 of the second spring 123 and a receiving portion 145 of the third spring 125 centering on the opening 141a of the movable block member 140, the second and third springs 123 and 125 are disposed. The interference on the movement can be reduced.

  In addition, since the boss portion 140a is formed around the opening 141a by the concave portion of the receiving portion 143 of the second spring 123, by preventing a sudden pressure reduction, the boss portion 140a can be used as a safer gas supply device. Play a role.

  At this time, when the height of the boss portion 140a is lowered, an effect of further expanding the space above the plunger 130 can be additionally achieved, so that excessive tension of the second spring 123 can be achieved. Even if the boss portion 140a is not reflected in the design, an additional function that can increase the efficiency of the design can be achieved by performing a stopper function that prevents the movable block member 140 from moving upward using the boss portion 140a. It becomes like this.

  Therefore, as can be seen from the above description, the plunger 130 built in the main body, that is, in the flow passage 101 is pressurized and moved by the press-fitting amount of the pressurizing button member 160, and the concave portion 133 of the plunger 130 is closed. Since the gap between the member 110 and the discharge port 111 is variable, the amount of discharge gas exhausted from the container S through the discharge port 111, the communication port 135 and the exhaust port 105 can be controlled.

  Thus, the present invention is hygienic and harmless to the body, and is convenient to use. Therefore, the present invention is excellently used as a simple oxygen inhaler not only for patients who require oxygen but also for general people.

  The above embodiment is a gas supply device (oxygen inhaler) in which a container is filled with oxygen, but is also suitable as an inhaler in which a container is filled with gas for treating asthma. Of course, this invention is not restricted to these, It can utilize as a gas feeder filled with arbitrary gas.
