Abstract
The utility model relates to the processing of plastic products and the production of heat insulating glass liners. The utility model is characterized in that a glass liner is made of plastic, and a vacuum layer is formed between the inner and the outer sleeves 1 and 2 of the glass liner. One layer heat reflecting shield 4 is additionally arranged in the vacuum layer, and metallic film layers 6 are plated on the walls of the vacuum layer and the heat reflecting layer. A water charging opening 7 is arranged on the upper part of the glass liner, and a self-flow water outlet 8 is arranged on the lower part of the glass liner. The utility model has the advantages of easy processing and manufacture and good heat insulating effect, and the use of a self-flow type thermos bottle accomplished by the utility model is very convenient.
Description
The utility model relates to plastic products processing and glass liner of thermos manufacturing.
The glass liner of thermos of prior art has the glass courage, and its character is crisp, and impact strength is poor, and it is difficult to produce, and yield rate is low; The metal courage is arranged, because of the metal heat-conducting coefficient is big, be incubated relatively poorly, and processing is also difficult, and cost is higher; The plastics vacuum heat-insulating container is arranged, and its structure is that vacuum wall does not add protection, but plastics intensity has certain limit, and vacuum pressure concerns again, the impact that often is collided in use, and be damaged easily in the driving fit position, and vacuum wall metallizing layer is also easily impaired.The prior art vacuum flask still rests on and carries on obforms and the hydrocone type (vapour-pressure type, Electric pump type) because of the relation of glass liner processing technology, and the gravity flow vacuum flask still can not be implemented commercialization production.The adiabatic problem of vacuum heat-preserving mainly be to solve thermal-radiating problem, and the multi-screen reflection can improve the radiation insulation effect exponentially, do not increase radiation shield but have in the prior art vacuum layer.
The purpose of this utility model is to solve the prior art deficiency, and a kind of easy processing is provided, and high insulating effect is applicable to the gravity flow glass liner of thermos of gravity flow vacuum flask.
Content of the present utility model and embodiment accompanying drawings are as follows:
Accompanying drawing is a kind of cutaway view of gravity flow plastics vacuum multi-screen glass liner of thermos.The 1st, cover in the glass liner, the 2nd, glass liner overcoat, the 3rd, vacuum layer, the 4th, heat reflection screen in the vacuum, the 5th, evacuation holes, the 6th, metallic diaphragm, the 7th, the glass liner dress mouth of a river, the 8th, glass liner gravity flow delivery port.
In the glass liner overcoat 1 and 2 and vacuum in heat reflection screen 4 be made of plastics, 1 one-shot forming of interior cover, heat reflection is shielded 4 waists and is truncated into up and down two halves and makes, overlap outside 1 in being placed in, waist connects fixing, and two halves were made about overcoat 2 waists were truncated into, and 4 outsides are shielded in cover 1 and heat reflection in covering in, connect method with waist and engage, the uniformly-spaced space that heat reflection screen 4 and interior cover 1 and overcoat 2 are maintained fixed; By evacuation holes 5, in glass liner, plate layer of metal rete 6 on overcoat vacuum layer and the heat reflection screen partition; Vacuumize by 5 pairs of vacuum layer 3 of evacuation holes, and sealing evacuation holes 5.
Dress water is loaded on glass liner from the dress mouth of a river 7, and water flows out from gravity flow delivery port 8 from pressing automatically because of deadweight.
The utility model is prior art relatively, has obvious characteristics and progress:
The easy processing and manufacturing of glass liner, the yield rate height, and in vacuum layer, add one deck heat reflection screen, and more effectively improve heat insulation effect, and Self-flow thermos bottle is realized easily, its high insulating effect, it is especially convenient to use.
Claims (3)
1, a kind of gravity flow plastics vacuum multi-screen glass liner of thermos is characterized in that comprising cover 1 in the glass liner, glass liner overcoat 2, vacuum layer 3, heat reflection screen 4 in the vacuum, evacuation holes 5, metallic diaphragm 6, the dress mouth of a river 7 and gravity flow delivery port 8.
2,, it is characterized in that heat reflection screen 4 is that plastics are made in the interior cover 1 of glass liner and overcoat 2 and the vacuum according to the described a kind of gravity flow plastics vacuum multi-screen glass liner of thermos of claim 1.
