Vacuumizing double-layer heat preservation glass cup

Abstract

A vacuumizing double-layer heat preservation glass cup comprises an inner container glass cup body, an outer layer glass cup body and a base, the inner container glass cup body is sleeved with the glass cup body, and the base is located at the bottom of the outer layer glass cup body; a cavity protruding upwards is formed in the center of the bottom of the inner container glass cup, and a vacuumizing preformed hole communicating downwards is formed in the center of the bottom of the outer layer glass cup; metal particles are placed in the vacuumizing preformed holes; and the base is connectedwith the bottom of the outer-layer glass cup. Compared with the prior art, the vacuumizing preformed hole is formed in the bottom of the outer-layer glass cup; the tops of the outer-layer glass cup and the inner-container glass cup are sealed and connected in a rolling manner; air between the outer-layer glass cup and the inner-container glass cup is pumped away through the vacuum pump; the innercontainer glass cup is arranged in the outer layer glass cup and reacts with air under the action of zirconium and vanadium, water vapor in a vacuum area between the outer layer glass cup and the inner container glass cup is adsorbed, the vacuum rate is increased, and meanwhile the vacuumizing closed tail bead formed after vacuumizing is shielded while the stability of the whole cup body is improved due to the arrangement of the base.

Description

technical field [0001] The invention belongs to the technical field of a double-layer thermal insulation glass, in particular to a vacuum-pumped double-layer thermal insulation glass. Background technique [0002] The thermos cup is a household item in a modern civilized society. In the past, the thermos cup made of 304 stainless steel has the advantages of long heat preservation time, anti-fall, and carrying when going out. Almost everyone has one. However, in recent years, as people pay more attention to the concept of health, more and more people have begun to return to the double-layer insulation glass made of high borosilicate glass, which is due to the high chemical stability of the glass material. [0003] However, in the manufacturing process of the traditional double-layer thermal insulation glass, it is often only a glass melting seal for the outer glass and the inner glass, without realizing the real vacuum process of interlayer air with tail, which is a kind of f...

Problems solved by technology

[0003] However, in the manufacturing process of the traditional double-layer thermal insulation glass, it is often only a glass melting seal for the outer glass and the inner glass, without realizing the real vacuum process of interlayer air with tail, which is a kind of false " Therefore, in the process of brewing tea, because it is not a vacuum, the outer glass wall will conduct the heat of boiling water, and the outer wall of the glass will still feel hot when grasped by hand. The temperature of the outer wall of the glass is at least 50 degrees. In addition, due to heat loss Fast, the tea cools down quickly, which directly affects the taste of drinking tea

[0004] In order to achieve long-term heat preservation effect, the outer wall of the inner tank glass and the inner wall of the outer glass are silver-plated to achieve heat preservation effect. The effect is very good, but its disadvantages are: the internal shape of the tea leaves cannot be seen, and the brewing effect of the tea leaves is not good if the temperature is too high, which will cause "stuffy tea". In addition, the silver plating process will affect the cleanliness of the glass surface High standard
