Description
Technical field
The utility model relates to a kind of vacuum flask, especially a kind of safety thermos flask.
Background technology
Thermos bottle also is vacuum flask, is a kind of container of containing hot water, and distributing of thermos flask heat is divided into conduction, convection current and radiation, and thermos flask has utilized this three's principle just.The bottle stopper of thermos flask is made of cork, and cork is difficult for heat conduction, has prevented the generation of conduction as far as possible; In the middle of the thermos flask is vacuum, prevents cross-ventilated generation as far as possible; Also have the glass liner of thermos flask to be plated to silvery white, non-radiating is gone out to bottle is interior can to make reflect heat.
At present, thermos flask plays an important role in our life, no matter be in the rural area or the city, every household is applying hot water bottles all; Its shell is generally by iron sheet, aluminum, plastics, and bottle stopper generally all is to make with stopper, and wooden bottle stopper of long duration will diminish, and contact with bottle bag edge and becomes flexible; Drop easily, add when fetching water, portable thermos bottle rocks a little; Bottle stopper also can drop, and the bottle stopper of making dirty is very unhygienic, if knock thermos bottle because of carelessness over; Thermos bottle will explosion, and hot water also can splash out, brings unnecessary damages to people.
The utility model content
In order to overcome the deficiency of above-mentioned existing product, the purpose of the utility model is to provide a kind of safety thermos flask; It is employed in glass liner open upper end place internal thread is set, and the bottle stopper lower end is provided with external screw thread.
For the technical scheme that purpose adopted that realizes the utility model is: a kind of safety thermos flask is characterized in that: it is made up of shell, base, glass liner, bottle stopper; Described shell is cylindric, and the upper end is provided with frustum and handle, and the lower end is provided with external screw thread and base, and the surface is provided with handle, and inside is provided with glass liner; Described base is discoid, and the upper end is provided with internal thread; Described bottle stopper is a cylinder, and the lower end is provided with external screw thread.
The beneficial effect of the utility model is: it can either effectively be incubated, and can bottle stopper be fixed again, is difficult for dropping; And it is simple in structure, economical and practical, widely applicable.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
Fig. 1 is the utility model structure chart
Fig. 2 is the utility model cutaway view
1-bottle stopper, 2-handle, 3-frustum, 4-shell, 5-handle, 6-base, 7-glass liner among the figure.
The specific embodiment
In Fig. 1, first embodiment shown in Figure 2, a kind of safety thermos flask is characterized in that: it is made up of shell, base, glass liner, bottle stopper; Described shell is cylindric, and the upper end is provided with frustum and handle, and the lower end is provided with external screw thread and base, and the surface is provided with handle, and inside is provided with glass liner; Described base is discoid, and the upper end is provided with internal thread; Described bottle stopper is a cylinder, and the lower end is provided with external screw thread.
In Fig. 1, second embodiment shown in Figure 2, described base is used for fixing glass liner, and the internal thread of its upper end and the external screw thread of shell lower end interconnect; Described frustum upper end is provided with opening, is fixed together with shell; Described glass liner is cylindric, and the upper end is provided with screwed hole, and its main purpose is to hot water thermal insulating, is made by special material, is difficult for breaking, and is safe; The external screw thread of described bottle stopper lower end and the screwed hole of glass liner interconnect, and play sealing and heat preservation effect; The effect of described handle is to be convenient for people to hand take.
When using the utility model, at first, turn on bottle stopper; Hot water is injected glass liner, then, turn round bottle stopper; Because the special material of glass liner, even there is the people to knock thermos bottle over, glass liner can explosion yet; Adding between bottle stopper and the glass liner is through being threaded, and the hot water in the glass liner can reach long insulation, and can not expose.
