See Figures 1 to 5:

The utility model provides a filling structure for edible carbon dioxide, comprising a carbon dioxide cylinder 1, an inflating head 2, and an inflating rod 6. The following describes in detail the various components of the filling structure for edible carbon dioxide:

The inflatable head 2 is welded on the top of the carbon dioxide gas cylinder 1, the upper surface of the inflatable head 2 is provided with a sealing hole 201, the sealing hole 201 is threadedly connected with a sealing plug 5, and the inside of the inflatable head 2 is provided with an inflatable jack 202, an inflatable jack 202 is located just below the sealing hole 201, the inner part of the air-filled jack 202 is slidably connected with the sealing slide block 3, the bottom of the sealing slide block 3 is fixedly connected with a return spring 4, and the other end of the return spring 4 is fixedly connected to the air-filled hole 202. On the bottom surface, air inlet holes 203 are opened on both sides of the bottom end of the air inlet hole 202;

Specifically, when the carbon dioxide gas cylinder 1 is not filled with carbon dioxide, the sealing slider 3 can seal the air inlet 203 to prevent the carbon dioxide in the carbon dioxide gas cylinder 1 from leaking out. The threaded connection can further seal the inflation head 2;

The inflatable rod 6 is inserted into the inflatable jack 202, the top of the inflatable rod 6 is fixedly connected with an air delivery pipe 7, the outer circumferential surface of the upper end of the inflatable rod 6 is threadedly connected with a fixing plug 8, and the fixing plug 8 is threadedly connected with the sealing hole 201, and the inflation is carried out. The outer circumferential surface of the bottom of the rod 6 is provided with an air outlet 601;

Specifically, carbon dioxide can be fed into the inflatable rod 6 through the gas delivery pipe 7, and then the carbon dioxide is discharged from the inflatable rod 6 through the air outlet 601;

Therefore, when the carbon dioxide cylinder 1 needs to be filled with carbon dioxide, the sealing plug 5 is first taken out from the sealing hole 201, and then the inflation rod 6 is inserted into the inflation hole 202 from the sealing hole 201, and the inflation rod 6 is pushed. Extend into the sealing hole 201, so that the top of the inflation rod 6 pushes the sealing slider 3 to slide to the bottom of the inflation hole 202. When the sealing slider 3 cannot continue to slide, it means that the inflation rod 6 has been inserted into the inflation hole 202, and then align the air outlet 601 with the air inlet hole 203, and then manually move the fixing plug 8 on the inflation rod 6, so that the fixing plug 8 moves to the sealing hole 201, and makes the fixing plug 8 Connect with the sealing hole 201, so that the upper end opening of the inflatable jack 202 can be sealed, and the inflatable rod 6 is also fixed in the inflatable head 2, and then the air delivery pipe 7 can pass through the inflatable rod 6 and the air outlet hole 601. Carbon dioxide is input into the air inlet 203, and the carbon dioxide is then discharged into the interior of the carbon dioxide cylinder 1 through the air inlet 203, thereby filling the carbon dioxide;

After the carbon dioxide is filled, the fixing plug 8 is unscrewed from the sealing hole 201, and then the inflation rod 6 can be pulled out from the inflation hole 202. When the inflation rod 6 is pulled out, the sealing slider 3 is lost. external force, then the return spring 4 will use the elastic force to push the sealing slider 3 back to its original position, so that the sealing slider 3 continues to seal the air intake hole 203 to prevent carbon dioxide leakage, and then screw the sealing plug 5 into the sealing hole 201, and further Seal.
