Abstract

The utility model relates to a double layered metal vacuum internal bladder, comprising an internal enclosure component, an external enclosure component and a vacuum interlayer formed by the internal enclosure component and the external enclosure component. The top of the internal enclosure component is fixedly sealed with the top of the external enclosure component. The bottom of the external enclosure component is opened with a vacuum opening which is fixedly sealed with a vacuum component. The utility model has the advantages of uneasy damage, firmness and duration, good sealing property and long thermal insulation time, etc., and is suitable for various thermal insulation cups, thermal insulation bottles and thermal insulation pots.

Description

A kind of double-level-metal vacuum liner

Technical field

The utility model relates to a kind of thermos cup, vacuum flask or thermo jug inner bag, specifically, is a kind of double-level-metal vacuum liner.

Background technology

At present, the thermos cup that people generally use, vacuum flask or thermo jug, its inner bag are glass inner bag, and this inner bag is broken easily, and suction is not high, and temperature retention time is short.

Summary of the invention

The purpose of this utility model is at above-mentioned the problems of the prior art, provides a kind of and is difficult for breaking, firm and durable, good seal performance, double-level-metal vacuum liner that temperature retention time is long.

The purpose of this utility model be achieved in that by interior go along with sb. to guard him part, peripheral protective part and by interiorly go along with sb. to guard him part, the peripheral protective part is gone along with sb. to guard him the interlayer that vacuumizes that forms and is constituted, in to go along with sb. to guard him the end sealing of top, peripheral protective part of part fixedly connected; The bottom of peripheral protective part offers a vacuum orifice, vacuum orifice with vacuumize part and be sealedly and fixedly connected.

The utility model according to heat radiation principle, can be provided with silver coating, copper plate or coat aluminium foil layer at the interior wall liner of going along with sb. to guard him outside the part.

The utility model, in go along with sb. to guard him within the part wall in courage mouth place or and the peripheral protective part outside wall be provided with screw thread in courage mouth place, screw thread and courage mouth plug coupling.

The beneficial effects of the utility model are because go along with sb. to guard him part in adopting, the spacer structure that vacuumizes that forms is gone along with sb. to guard him in the welding of peripheral protective part, be difficult for breaking, firm and durable and good seal performance; In go along with sb. to guard him part, the peripheral protective part is molded by metal pattern, vacuumize the back negative pressure little, reach 10 ^-3The MPa level vacuumizes 10 of back negative pressure than glass inner bag ^-1The MPa level is little two orders of magnitude are so temperature retention time is long.Have be difficult for breaking, firm and durable, good seal performance, advantage that temperature retention time is long, the utility model is suitable for various thermos cups, vacuum flask or thermo jug and uses.

Following embodiment accompanying drawings is further described the utility model.

The specific embodiment

Referring to figs. 1 through Fig. 4, embodiment 1 by interior go along with sb. to guard him part 1, peripheral protective part 2 and by interiorly go along with sb. to guard him part 1, peripheral protective part 2 is gone along with sb. to guard him the interlayer 3 that vacuumizes that forms and is constituted, in go along with sb. to guard him the top 4 of part 1, the top 5 of peripheral protective part 2 is sealedly and fixedly connected; The bottom of peripheral protective part 2 offers a vacuum orifice 6, vacuum orifice 6 with vacuumize part 7 and be sealedly and fixedly connected; Go along with sb. to guard him interior that wall liner is provided with silver coating 8 outside the part 1; Go along with sb. to guard him interior that wall is provided with screw thread 10 in courage mouth 9 places within the part 1, this screw thread 10 can with courage mouth plug 11 couplings.

With reference to Fig. 5, embodiment 2 compares with embodiment 1, in go along with sb. to guard him that wall is not provided with screw thread in courage mouth 9 places within the part 1.

Manufacturing of the present utility model, in go along with sb. to guard him part 1, the peripheral protective part 2 general stainless steel materials that adopt, by the mould compression molding, in go along with sb. to guard him part 1, peripheral protective part 2 and vacuumize interlayer 3 structures by what butt-joint was gone along with sb. to guard him, peripheral protective part 2 also with vacuumize part 7 butt-joints and be connected, after vacuumizing by special equipment, make inner bag 17.

Assembling of the present utility model is used, the thermo jug of Fig. 6 to Fig. 8, and support member 14 at the bottom of the kettle that install 12 bottoms that stay at kettle lower house 13 at the bottom of the inner bag, courage mouth 9 stays at kettle mouth 15, kettle upper shell 16 and kettle lower house 13 is screwed again, and thermo jug is promptly assembled and is finished.
