A gas charging check valve uses a first elastic element and a second elastic element, which respectively provide elastic force on a top valve and a bottom valve. The top valve and the bottom valve correspond to each other as a set. When the gas charging device is moved to apply an external force on a movement control portion of the gas charging check valve, the second elastic element removes the elastic force applied on the bottom valve to reduce the required gas inject force for a valve formed by the top valve and the bottom valve, so that the gas can more easily enter the valve.

1. A gas charging check valve comprising: a top cover portion comprising a top cover fixing portion, a first elastic element, a top valve and a cover body, wherein the first elastic element is disposed between the top valve and the cover body, and wherein elastic force is applied on the top valve by the first elastic element; anda bottom cover portion comprising a bottom cover fixing portion, a second elastic element, a movement control portion and a bottom valve, wherein the movement control portion has a protrusion portion, wherein the movement control portion is disposed between the second elastic element and the bottom valve, wherein the second elastic element applies elastic force on the movement control portion, and wherein the elastic force of the second elastic element is applied on the bottom valve with the movement control portion;wherein the top cover fixing portion and the bottom cover fixing portion are joined correspondingly, wherein the cover body is embedded on the top cover fixing portion with the first elastic element, the top valve, the second elastic element, the movement control portion and the bottom valve disposed inside the top cover fixing portion and the bottom cover fixing portion, wherein the protrusion portion protrudes outside the bottom cover fixing portion, and wherein when the protrusion portion of the movement control portion is moved by an external force, the elastic force exerted on the bottom valve by the second elastic element is removed. 2. The gas charging check valve claimed in claim 1, wherein the top valve extends downwardly with a first cylinder, wherein the bottom valve extends upwardly with a second cylinder, and wherein the first cylinder and the second cylinder correspond to each other to form a valve for controlling gas in and out. 3. The gas charging check valve claimed in claim 1, wherein the second elastic element is a spring, and wherein the movement control portion further comprises a groove corresponding to the spring with a portion of the spring embedded in the groove. 4. A precision component container apparatus having a gas charging check valve, wherein the precision component container apparatus comprises: a container body having an opening; anda door body corresponding to the opening for sealing the opening; wherein a through hole is disposed in the door body or the container body, and wherein the gas charging check valve is embedded in the through hole for controlling gas in and out; wherein the gas charging check valve comprises:a top cover portion comprising a top cover fixing portion, a first elastic element, a top valve and a cover body, wherein the first elastic element is disposed between the top valve and the cover body, and wherein elastic force is applied on the top valve by the first elastic element; anda bottom cover portion comprising a bottom cover fixing portion, a second elastic element, a movement control portion and a bottom valve, wherein the movement control portion has a protrusion portion, wherein the movement control portion is disposed between the second elastic element and the bottom valve, wherein the second elastic element applies elastic force on the movement control portion, and wherein the elastic force of the second elastic element is applied on the bottom valve with the movement control portion;wherein the top cover fixing portion and the bottom cover fixing portion are joined correspondingly, wherein the cover body is embedded on the top cover fixing portion with the first elastic element, the top valve, the second elastic element, the movement control portion and the bottom valve disposed inside the top cover fixing portion and the bottom cover fixing portion, wherein the protrusion portion protrudes outside the bottom cover fixing portion, and wherein when the protrusion portion of the movement control portion is moved by an external force, the elastic force exerted on the bottom valve by the second elastic element is removed. 5. The precision component container apparatus claimed in claim 4, wherein the top valve extends downwardly with a first cylinder, wherein the bottom valve extends upwardly with a second cylinder, and wherein the first cylinder and the second cylinder correspond to each other to form a valve for controlling gas in and out.
