A third object of the present invention is to provide a seal around the first face glass and the second face glass.

According to a fourth aspect of the present invention, the first surface glass or the second surface glass is further provided with an air suction port, and the air suction port is sleeved with a sealing tube.

A fifth object of the invention is that the support is one of a dot, a thread or a mesh.

A sixth object of the present invention is that the support exhibits a structure in which the two ends are small and large, and the two ends are portions which are in direct contact with the glass on both sides.

Fig. 1 is a schematic view showing the structure of the present invention.

In order to make the technical solutions, technical features, achievement goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

According to Fig. 1, the present invention is a vacuum glass comprising a first face glass 1, a second face glass 2 and a third face glass 3 which are vertically stacked, wherein the first face glass 1 and the second face are A vacuum layer 5 is disposed between the face glass 2; a hollow layer 9 filled with an inert gas is disposed between the second face glass 2 and the third face glass 3; and a vacuum layer of the first face glass 1 and the second face glass 2 The outer edge of 5 is closed by a sealant layer 6, and the outer edge of the hollow layer 9 of the second face glass 2 and the third face glass 3 is closed by another sealant layer 6, and the vacuum layer 5 and the hollow layer 9 are closed. A plurality of supports 8 are provided to support the glass on both sides. A receiving groove 4 is respectively disposed on the first surface glass 1 and the third surface glass 3 corresponding to the side surface of the vacuum glass, and a gas pipeline 7 is disposed in the receiving groove 4; the gas pipeline One end of 7 extends to the outside of the vacuum glass and forms a closed end 10, the other end of which is in communication with the vacuum layer 5 or the hollow layer 9, and the gas line 7 extending to the outside of the vacuum glass The closed end 10 forms a closed space with the vacuum layer 5 or the hollow layer 9 through the gas line 7.

In the actual manufacturing process, after the vacuuming operation of the vacuum layer 5 is completed, the gas pipe 7 is closed to the outer side of the vacuum glass by heat melting or the like to form the closed end 10; After the inflation operation of the hollow layer 9, the gas line 7 is closed to one end of the outer side of the vacuum glass by heat melting or the like to form the closed end 10.
