Abstract
An easy-to-draw vacuum thermos bottle plug mainly comprises a hollow bottle plug (3), an inversed U-shaped ring (1) and a sealing ring (4), wherein the inversed U-shaped ring (1) is fixedly connected on the big diameter end surface of the hollow bottle plug (3) of a sealing circular cone body whose inner is vacuumed, and a user can stretches a finger into the inversed U-shaped ring (1), which is convenient to lift the bottle plug. The elastic sealing ring (4) is sleeved on the arc surface of the circular cone, which can facilitate the easy-to-draw vacuum thermos bottle plug to match with a thermos bottle neck and form sealing environment. The easy-to-draw vacuum thermos bottle plug is not only easily pulled out, but also the inner of the plug is vacuumed, and the bottle plug has low heat conductivity, no specific smell of wood and long service life, is sanitary and clean, and saves energy sources.
Description
Technical field:
The utility model relates to a kind of daily necessities, is specifically related to a kind of vacuum plug of thermos with better heat-insulating property.
Background technology:
Present known plug of thermos mostly is circular cone stage body cork.Because cork self has the special odor of timber, pollutes the hot water in the bottle easily, especially new bottle stopper is even more serious; Cork adhesional wetting back thermal conductivity factor increases in addition, is the main path of the hot water heat radiation in the thermos flask, has also caused a lot of wastes thus, if the heat of the whole thermos flasks of cumulative calculation scatters and disappears, the energy of waste is huge; When cork used, smaller diameter end faced down and fills in the bottle, and the major diameter end face lacks the application point of suitable power, particularly in the winter time, usually is difficult to extract because of the inner and outer air pressure difference.
Summary of the invention:
Pollute weak points such as hot water, thermal conductivity is high and be difficult to extract for overcoming existing thermos flask cork, the utility model proposes a kind of easy pulling vacuum plug of thermos, not only extract easily, and inside vacuumizes, thermal conductivity is low, no timber special odor.
The technical scheme that its technical problem that solves the utility model adopts is:
Easily the pulling vacuum plug of thermos mainly is made of hollow bottle stopper (3), inverted U-shaped finger ring (1) and sealing ring (4).Be consolidated with inverted U-shaped finger ring (1) on the major diameter end face of the hollow bottle stopper of O-ring cone table (3) that inside is evacuated, the user can stretch into finger in the U-shaped finger ring (1), is convenient to bottle stopper is proposed.Be with elastic seal ring (4) on the frustum of a cone cambered surface, can help easy pulling vacuum plug of thermos to cooperate and form sealed environment with the thermos flask mouth;
The utility model also has following feature:
The major diameter end face of hollow bottle stopper (3) is provided with sealed mouth (2), and before not vacuumizing, sealed mouth (2) in a tubular form, be communicated with hollow bottle stopper inner air and outer air, vacuumize when finishing, heat is melted involution makes its sealed mouth (2) that forms sealing, can effectively keep the vacuum environment in the bottle stopper;
The major diameter end face of hollow bottle stopper (3) is provided with the skin minute surface (6) of aluminizing, when the material of hollow bottle stopper (3) is glass or other transparent materials, but the usable reflection heat radiation;
The minor diameter end face internal layer of hollow bottle stopper (3) is provided with the internal layer minute surface (5) of aluminizing, when the material of hollow bottle stopper (3) is glass or other transparent materials, but the usable reflection heat radiation; Internal layer minute surface (5) and the skin minute surface (6) of aluminizing of aluminizing can exist simultaneously, also can only keep one of them.If adopting hollow bottle stopper is the technical scheme of nontransparent material, the minute surface that then need not to aluminize reflection.
The material of hollow bottle stopper (3) can be glass, heat resistant plastice.
The beneficial effects of the utility model are: easily the pulling vacuum plug of thermos is not only extracted easily, and inside vacuumizes, and thermal conductivity is low, no timber special odor, long service life, hygiene, energy savings.

The specific embodiment:
As shown in Figure 1: easily the pulling vacuum plug of thermos mainly is made of hollow bottle stopper (3), inverted U-shaped finger ring (1) and sealing ring (4).Be consolidated with inverted U-shaped finger ring (1) on the major diameter end face of the hollow bottle stopper of O-ring cone table (3) that inside is evacuated, the user can stretch into finger in the inverted U-shaped finger ring (1), is convenient to bottle stopper is proposed.Be with elastic seal ring (4) on the frustum of a cone cambered surface, can help easy pulling vacuum plug of thermos to cooperate and form sealed environment with the thermos flask mouth, in the present embodiment, sealing ring is that wall thickness is the frustum of a cone tubular rubber ring of 3mm, and material can be multiple elastomeric materials such as silica gel, modified resin.Hollow bottle stopper (1) internal vacuum is identical with the vacuum of glass liner for vacuum flask.The major diameter end face of hollow bottle stopper (3) is provided with sealed mouth (2), and present embodiment is located at the root of inverted U-shaped finger ring (1) one side, can avoid unexpected touching and scuffing.Before not vacuumizing, sealed mouth (2) is communicated with hollow bottle stopper inner air and outer air in a tubular form, vacuumizes when finishing, and heat is melted involution makes its sealed mouth (2) that forms sealing, can effectively keep the vacuum environment in the bottle stopper.The major diameter end face of hollow bottle stopper (3) is provided with the skin minute surface (6) of aluminizing, when the material of hollow bottle stopper (3) is glass or other transparent materials, but the usable reflection heat radiation; The minor diameter end face internal layer of hollow bottle stopper (3) is provided with the internal layer minute surface (5) of aluminizing, when the material of hollow bottle stopper (3) is glass or other transparent materials, but the usable reflection heat radiation; Internal layer minute surface (5) and the skin minute surface (6) of aluminizing of aluminizing can exist simultaneously, also can only keep one of them, is the technical scheme of nontransparent material if adopt hollow bottle stopper, the minute surface that then need not to aluminize reflection.Hollow bottle stopper (3) can be that glass, heat resistant plastice etc. are nonpoisonous and tasteless, has certain thermoplasticity, and the material that thermal conductivity is low adopts glass in the present embodiment.
