Title: VACUUM GLASS PRODUCT
Abstract:
A vacuum glass product, comprising: a first glass substrate (6); a second glass substrate (10) disposed opposite to the first glass substrate (6); a sealing structure (12) provided between the first glass substrate (6) and the second glass substrate (10) and used for airtight binding of the first glass substrate (6) and the second glass substrate (10) to form a vacuum cavity (11); and a support (2) provided inside the vacuum cavity for bearing pressure from the first glass substrate (6) and the second glass substrate (10). The sealing structure (12) comprises: metal layers (7, 9) which are fixedly bound to opposite surfaces of the first glass substrate (6) and the second glass substrate (10), respectively, and an intermediate solder layer (10) which connects the two metal layers. The sealing structure has arc-shaped transition structures at the corner areas of the glass substrates. By changing the shape of the sealing structure at the corner areas of the glass substrates, i.e., replacing break corners with arc-shaped transition, the time for repeatedly heating internal corner parts of a welding strip is reduced during induction welding and heating of the welding strip at the corner areas is more uniform.
