Abstract

A dual-layer anury vacuum glass thermos cup is characterized in that the cup body is formed into a vacuum body through an intussusception interior liner and a shell, wherein the interior liner fixedly connects with the shell at the cup-mouth and the bottom of the shell is equipped with exhausting holes whose shell bottom is equipped with slots wherein glass welding materials for blocking the exhaustion holes is embedded and fixedly connected. The utility model forms the vacuum layer between the interior liner and the shell the processes of air extraction, heating, welding and cooling due to the vacuum welding technique, and the cup body has excellent heat preservation performance with a smooth bottom of the anury conformation and simple manufacturing arts.

Description

Double-deck anury vacuum glass heat-insulating cup

Technical field:

The utility model relates to the double-layer heat insulation glass.

Background technology:

Double-layer glass obtains liking of consumer because of the appearance of its heat-insulating property and cleaning.But existing double-layer glass does not pass through emptying process, and its heat-insulating property is very undesirable.

For glassware, adopt the existing mode that vacuumizes, the blast pipe of protrusion must externally be set, this mode had both influenced attractive in appearance, and simultaneously, the blast pipe that afterbody protrudes is easy to break and leaks gas, thereby makes it lose the function of insulation.

The mode that adopts blast pipe to vacuumize is because the tailpipe easy fracture causes the finished product rate to descend.

Summary of the invention:

The utility model is for avoiding above-mentioned existing in prior technology weak point, the double-deck anury vacuum glass heat-insulating cup that a kind of preparation technology is simple, yield rate is high being provided.

The technical scheme that the utility model technical solution problem is adopted is:

The architectural feature of the utility model dual-layer vacuum glass thermos cup is, cup constitutes vacuum interlayer by the inner bag and the shell of intussusception, described inner bag and shell are fixed at the rim of a cup position, bottom at described shell, steam vent is set, the outer casing bottom at position, steam vent place is fluted, embeds and be consolidated with the glass solder that steam vent is formed shutoff in the groove.

Preparation of the present utility model is operated as follows:

1, described inner bag and shell all are blank with the glass tubing;

2, the inner bag tube billet is shaped to the band cup inner bag at the end by the high temperature rotary-cut;

3, it is fixed at the rim of a cup position that the mode that adopts high temperature to press solidly makes the front end of shell tube billet and inner bag, and compression moulding is a glass neck;

4, the tail end of shell tube billet is shaped to the band cup shell at the end by the high temperature rotary-cut;

5, to outer casing bottom local heating, at intensification position compacting groove, groove central authorities reserve steam vent;

6, rim of a cup is downward, puts into glass solder in groove, heats in the vacuum atmosphere, until glass solder and steam vent welding, handles through cooling again, and solder solidification forms vacuum interlayer between inner bag 1 and shell 2.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model bottom of cup is smooth, good looking appearance, good heat insulating.

2, the utility model bottom of cup vent structure is reliable, is difficult for gas leakage.

3, the utility model preparation technology is simple, reliable, the yield rate height.

Description of drawings:

Fig. 1 is the utility model cup body structure schematic diagram.

Fig. 2 is the utility model inner bag tube billet schematic diagram.

Fig. 3 is the utility model shell tube billet schematic diagram.

Fig. 4 is the utility model inner bag shaping schematic view.

Fig. 5 is the utility model inner bag and shell shaping schematic view.

Number in the figure: 1 inner bag, 2 shells, 3 steam vents, 4 grooves, 5 glass solders, 6 inner bag tube billets, 7 shell tube billets.

Below by embodiment, in conjunction with the accompanying drawings the utility model is further described.

Embodiment:

Referring to Fig. 1, cup constitutes vacuum interlayer by the inner bag 1 and the shell 2 of intussusception, and inner bag 1 is fixed at the rim of a cup position with shell 2, in the bottom of shell 2 steam vent 3 is set, shell 2 bottoms at position, steam vent 3 place are fluted 4, embed and be consolidated with the glass solder 5 that steam vent is formed shutoff in the groove 4.

Concrete preparation operation as follows:

1, with the glass tubing is inner bag tube billet 6 and shell tube billet 7 respectively;

2, inner bag tube billet 6 is shaped to the band cup inner bag 1 at the end by the high temperature rotary-cut;

3, the mode that adopts high temperature to press solidly makes shell tube billet 7 fixed at the rim of a cup position at its front end and inner bag 1, and compression moulding is the cup neck;

4, the tail end of shell tube billet 7 is shaped to the band cup shell 2 at the end by the high temperature rotary-cut;

5, to the bottom local heating of shell 2, at intensification position compacting groove 4, the central authorities of groove 4 reserve steam vent 3;

6, rim of a cup is downward, puts into glass solder 5 in groove 4, and heating in the vacuum atmosphere, until glass solder 5 and steam vent welding is handled through cooling again, and solder solidification forms vacuum interlayer between inner bag 1 and shell 2;

In concrete the enforcement, above-mentioned steps 1 to step 4 is the common process of preparation double-layer glass in the prior art.

In the step 5, local heating makes this local softening to 550-600 ℃, at softening position compacting groove.

In the step 6, used glass solder 5 is a glass particle; Concrete operations mode in this step is: at first cup to be formed is sent in casing, a case is vacuumized make the case internal gas pressure be not less than 1 * 10 ^-1Pa; Subsequently, in No. two casings of cup handover, heating up in No. two casees reaches 600-640 ℃, and the case internal gas pressure is not less than 1 * 10 simultaneously ^-3Pa,, this situation had both kept the cup form, made the scolder thermosol again, and fused with steam vent; At last, cup is transplanted in No. three casings, with 1 * 10 ^-1The air pressure of Pa carries out pressurize, and is fixed until solder cools.
