A vacuum glass with an air extraction channel

Abstract

The invention discloses a vacuum glass with an air extraction channel, comprising upper glass, lower glass and a vacuum layer formed between the upper glass and the lower glass, close to the edge between the upper glass and the lower glass A supporting frame and a sealing ring for sealing are arranged at the place, the sealing ring is located on the outside of the supporting frame, supports are evenly distributed in the vacuum layer, an air extraction channel is arranged in the supporting frame, and the supporting frame is close to On one side of the inner side of the vacuum layer, a plurality of first ventilation holes are arranged at equal intervals along its circumference, and the first ventilation holes communicate with the air extraction channel. A groove is installed on the side wall of the support frame, and the inner part of the installation groove A suction hole is provided on the bottom wall, and the suction hole communicates with the suction passage, and a getter is provided in the installation groove. The invention can release the getter after the exhaust is completed, and then absorb the residual gas in the vacuum layer, and can keep the vacuum degree in the vacuum layer continuously when the vacuum glass is used later.

Description

technical field [0001] The invention relates to the technical field of vacuum glass, in particular to a vacuum glass with a pumping channel. Background technique [0002] Vacuum glass is a glass product in which two pieces of flat glass are separated by supports, and the edges of the two pieces of flat glass are sealed to form a vacuum layer between the two pieces of glass. Vacuum glass is widely used in various fields due to its advantages of low carbon energy saving, heat insulation, sound insulation and noise reduction. [0003] However, after the existing vacuum glass is evacuated during production, some gas still remains in the vacuum layer inside, which makes the vacuum degree insufficient, and in the later use of the vacuum glass, as time goes by, insufficient sealing will occur. The problem is that a small amount of gas enters the vacuum layer, further reducing the vacuum. Contents of the invention [0004] The purpose of the present invention is to solve the sho...
