Abstract: Provided is a vacuum pumping device and a related method for manufacturing a vacuum glazing. The vacuum pumping device includes: a circular tubular pumping operation unit; a cylindrical pump-out hole sealing operation unit; a control part; and a driving device. The pumping operation unit and the pump-out hole sealing operation unit share a central axis, and form a cylinder with the former being outside and the latter being inside. A pumping channel is formed in a tube wall of the pumping operation unit, and a heating unit is disposed in the top portion inside the pump-out hole sealing operation unit. The control part time-sequentially controls the pumping operation unit and the pump-out hole sealing operation unit to move, controls the pumping channel to perform operations, and controls the heating unit to heat a sealing sheet to perform a pump-out hole sealing operation.

Abstract: An encapsulated getter arranged in vacuum glazing comprising an encapsulating box and a getter placed in the encapsulating box. The encapsulating box forms a closed cavity, and there is a gap between the getter and an inner surface of the encapsulating box. The position of the getter can be fixed with respect to the encapsulating box by filling material which is air permeable and thermal insulating in the gap.

Abstract: A pillar arranged in vacuum glazing, the pillar is ring-shaped or column-shaped, wherein at least one groove whose depth is no greater than the thickness of the pillar is formed on the upper surface and/or the lower surface of the pillar. The pillar could be made of metallic material such as stainless steel or other metal or alloy whose hardness is high enough, or non-metallic material such as ceramics or special glass.
