[0020] gas supply device of Reference numeral 10 expression oxygen uptakes comprises control valve 100, is threaded onto the gas source S that is included in the Compressed Gas in the high-pressure bottle, and is configured to the emitted dose of Compressed Gas is controlled to be a preset value.
[0021] in addition, control valve 100 comprises gas channel 101, piston 130, removable 140, removable valve member 150 and push button element 160.
[0022] in gas channel 101, it comprises a part longitudinal extension of an end, be communicated with the inner space of the body 109 of control valve 100, comprise that another part of the other end is communicated with the outlet 111 of the middle body that is formed on the closure member 110 that is fixedly attached to gas source S.Piston 130 is supported in the inside of gas channel 101, so that first spring 121 applies elastic force along the direction of upwards leaving outlet 111 to piston 130.Piston 130 closely contacts with gas channel 101, so that it can longitudinal sliding motion in gas channel 101.
[0023] removable 140 by second spring 123 along towards the direction resiliency supported of the high-pressure bottle of gas source S above piston 130, and in gas channel 101.Removable 140 can longitudinal sliding motion in gas channel 101.
[0024] removable valve member 150 has pole 151, and it extends through the central opening 141a that is defined in removable 140.Removable valve member 150 also has valve seat 153 and valve body 155, described valve seat 153 and valve body 155 and pole 151 whole combinations, with around with the bottom of sealing opening 141a.
[0025] push button element 160 is supported by an end of the 3rd spring 125, and this spring other end is supported on the removable valve member 150.Push button element 160 has patchhole 151a, and the pole protruding upward 151 of removable valve member 150 is inserted in it, in order to fixed support push button element 160.
[0026] lip ring 141 is fixedly connected on removable 140 bottom.
[0027] in addition, be used for second spring base 143 that second spring 123 is installed is within it centered on removable 140 the coaxial formation of central opening 141a with the local dent shape.The same with second spring base 143, the 3rd spring base 145 is formed between removable 140 the central opening 141a and second spring base 143 so that the local dent shape is coaxial.
[0028] in addition, the space 131 that is formed at piston 130 tops has the shape of upwards widening.
[0029] in addition, the outlet 111 that is formed at closure member 110 middle bodies has the nozzle form of protrusion, and piston 130 has the groove 133 that is formed at its bottom, with the outlet 111 of holding protrusion.
[0030] cup-shaped lid 11 is connected to the top of control valve 100, and has boss 11a, and described boss 11a protrudes, so that insert the outlet 105 of control valve 100 in it.
[0031] Reference numeral 133a represents sealing, and described sealing is used to seal the hole of outlet 105, and Reference numeral O represents to be used to keep the O type ring that seals, and Reference numeral 135 expressions are formed at the through hole that is communicated with in the piston 130, with the space 131 of piston 130.The fastener of Reference numeral 160 expression support piston 130.Fastener 160 has the bottom that screw thread inserts seal 110.Reference numeral 170 expression lids, itself and fastener 160 whole combinations, and as the lower cover of control valve 100.Upper guide member of Reference numeral 180 expressions, it is by the upper bond of padlock portion 171 with lid 170.Upper guide member 180 has the outstanding padlock projection 181 that is formed at its side, with the lengthwise movement of call-on button spare 160.
[0032] the following operation that gas supply device of the present invention will be described.
[0033] at first, when push button element 160 is pressed down when moving to predetermined depth, the removable valve member 150 that combines with push button element 160 moves down (see figure 2).With moving of removable valve member 150, valve body 155 and valve seat 153 are opened the opening 141a on removable 140.
[0034] since the top of piston 130 by first spring 121 fexible bias pressure upwards, so the gas among the gas source S enters by through hole 135, this through hole forms along the direction that vertically intersects vertically with piston 130.
[0035] in addition, when the valve seat 153 of removable valve member 150 moves towards the opening of gas channel 101, when reducing the open degree of opening 141a, push button element 160 slightly moves up.Because the top sectional area of piston 130 is long-pending greater than lower section, so piston 130 moves down the outlet 111 on the sealing closure member 110.
[0036] therefore, when push button element 160 is slightly pressed down, piston 130 moves down, thus reduced via the outlet 105 on the removable valve member 150 with the amount of the gas of outlet 105 lids that link to each other 11 injections.When push button element 160 is firmly pressed down, when increasing the jet amount via outlet 105, piston 130 further moves up, increase with the jet amount that increases via the outlet 111 of closure member 110, and the collaborative jet amount that has increased via outlet 105.Therefore, the gas emitted dose can be controlled automatically according to the depression degree of push button element 160.
[0037] simultaneously since have powerful pressure in the gas channel or between the motion of the motion of removable valve member 150 and piston 130 life period at interval, so may there be improper high pressure in piston 130 tops.This can cause removable 140 to float, thereby has overcome the elastic anchorage force of second spring 123 that supports removable 140.
[0038] therefore, collaborative removable 140 move, the valve body 155 of removable valve 150 and valve seat 153 are opened the opening 141a of gas channel 101.This has alleviated the improper high pressure of piston 130 tops, thereby has realized a kind of safer gas container or gas supply equipment.
[0039] in addition, by centering on second spring base 143 and the 3rd spring base 145 of removable 140 opening 141a, can reduce second spring 123 and the 3rd spring 125 when motion, the interference between them.
[0040] in addition, boss 141 in the inner boundary of opening 141a, is prevented that unexpected pressure from descending by the indentation limitations on second spring base 143.Therefore, the gas supply is with safer and stable.
[0041]。When the height of boss 141 descended, the space of piston 130 tops further increased.Therefore, although do not consider the excessive tension of second spring in the design of gas supply device, boss 141 can be used as removable 140 backstop that moves upward, thereby has improved design efficiency.
[0042] describes in detail as can be known as the aforementioned, the amount that is pressed down according to push button element 160, the gas channel 101 interior pistons 130 that are arranged on body 109 are pressed down and move, and hold the groove of piston 130 and the gap between the outlet 111 on the closure member 110 thereby change.Under this mode, can control from gas source S by export 111, through hole 135 and export 105 gas flows that spray.
[0043] therefore, the gas supply device among the present invention is that cleaning is harmless and easy to use, therefore can be the patient or other crowds that need oxygen uptake and uses as simple respirator.
[0044] according to the present invention as described hereinbefore, the amount such as the gas of oxygen of spraying internally can in use be controlled by pressing down removable push button element, thereby regulates emitted dose to adapt to user's demand.Therefore, the present invention can realize safer gas supply device, and this can promote user's health.In addition, because the gas supply can be set to the stage form, so can overcome the inconvenience that frequent adjustments of gas feeding mechanism is caused.
[0045] though describe the present invention with reference to certain embodiments and accompanying drawing, the present invention not only is confined to this, and should be as the criterion with appending claims.Be understandable that those skilled in the art can be under the situation that does not break away from category of the present invention and design, described embodiment is carried out various forms ofly substituting, transforming or revise.
