Background

The sealing mode of the vacuum process in the existing metal piece vacuum cup industry is mainly divided into two types: one is a tail seal; one is a tailless seal. The tail sealing is that the bottom of the vacuum cup has a small tail after the vacuum pumping is finished, the process is that a copper pipe (the welding tightness is good) is welded on a hole for pumping air of the vacuum cup, the size and the aperture of the copper pipe are the same, interlayer air between an inner pipe and an outer pipe of the vacuum cup is pumped completely through the copper pipe, the copper pipe is cut after the vacuum pumping is finished, and the copper pipe is deformed to achieve a sealing state when the copper pipe is cut, but a section of the copper pipe is remained at the bottom of the vacuum cup. The tailless vacuum is that a little glass is placed to the hole next door with the pumped air on the thermos cup pipe bottom, then put into a sealed environment with the thermos cup, take out into vacuum in the sealed environment, and heat for this space when taking out into vacuum, wait the vacuum take out a definite value after, the temperature of heating also reaches the value that melts glass, through glass melt the hole of thermos cup bottom sealed, thereby obtain this technology thermos cup bottom of the inside vacuum of thermos cup and can not leave like there being the copper pipe of tail.
