Embodiment
Elliptical cavity formula vacuum flask and its heat preserving method are described in further detail in conjunction with accompanying drawing.
As shown in Figure 1, Figure 2 and shown in Fig. 3, elliptical cavity formula vacuum flask include stainless steel inner container 1, ovallized column body case 2,
Strip convex lens 3, plastics thermal insulation fixture 4, opening capping 5, bottle cap 6 and vacuum flask hand handle 9.Stainless steel inner container 1 is placed in outer
Inside shell 2, the shell 2 is a hollow cylinder, and the cross sectional shape of cylinder is ellipse, the central axis of stainless steel inner container 1 with
First focal line of ovallized column body case 2 overlaps；Longitudinal opening is provided with the side wall of ovallized column body case 2, opening is cut
Face is disposed in proximity to the elliptical head of the second focal line, and strip convex lens 3 are provided with the aperture position.
The stainless steel inner container 1 is the cylindric inner bag being made of stainless steel, and its outer surface coats light absorption coating, with
Strengthen its absorption to light, the central axis of stainless steel inner container 1 overlaps with the first focal line of ovallized column body case 2.
Adiabatic fixture 4 is placed in the bottom of stainless steel inner container 1, for fixing stainless steel inner container 1；The bottle cap 6 of stainless steel inner container 1
It is connected by helix with the bottle sealing of stainless steel inner container 1；The adiabatic material of fixture 4 is plastics, can both prevent heat from damaging
Lose, stainless steel inner container 1 can be fixed again.
There is an opening in the ovallized column body case 2, ovallized column body case 2 is except aperture position, inner surface whole
Silver coating 7 is coated, prevents thermal loss and sunlight reflection.Between the inner surface of ovallized column body case 2 and outer surface
Heat-preservation cotton 8 is filled, further prevents thermal loss.The entrance being open for sunray, opening is bigger, can enter ellipse
Light inside cylinder shell 2 is more, meanwhile, the heat lost by opening is also more, and the size of opening determines guarantor
The heat insulation effect of warm bottle；
It is evacuated inside ovallized column body case 2, prevents thermal convection current.
Strip convex lens 3 are arranged on the aperture position of ovallized column body case 2, and strip convex lens 3 and ovallized column are external
The opening of shell 2 is tightly connected.

After primary event, the first focal line of ovallized column body case, the central axis of stainless steel inner container and the first focal line are necessarily passed
Overlap, so the sunray after focusing on is impinged upon on stainless steel inner container, stainless steel inner container is heated, stainless steel inner container is by warm
Amount passes to the article of the inside；
(4) when elliptical cavity formula vacuum flask is idle (when such as night is without the sun), by opening cap cover in strip convex lens
Outside.
The operation principle labor of the present invention is as follows：The inner surface of ovallized column body case 2 silver-plated 7, its inner surface and outer
Heat-preservation cotton 8 is filled between surface, the opening strip convex lens 3 of ovallized column body case 2 encapsulate, elliptical cavity formula vacuum flask
Inside is evacuated 10, the central axis of stainless steel inner container 1 is placed on the first focal line of ovallized column body case 2, stainless steel
The bottom plastics thermal insulation fixture 4 of inner bag 1 is fixed, it would be desirable to which the article of insulation is placed in stainless steel inner container 1, if finding stainless steel
Article has cooled down in inner bag 1, the strip convex lens 3 of elliptical cavity formula vacuum flask can be faced into the sun, directional light 11 is first
The second focal line of ovallized column body case 2 is focused on by strip convex lens 3, by the focal line of ovallized column body case 2 second
Sunshine can be radiated at after primary event to be placed on the stainless steel inner container 1 of the focal line of vacuum flask first, and stainless steel inner container 1 is entered
Row heating, so as to be heated to the article in vacuum flask., can be by adjusting vacuum flask when the sun is in sky diverse location
The internal layer of hand handle 9 faces the sun all the time to adjust strip convex lens 3, so that more sunrays enter elliptic cylindrical
Shell 2.
The present invention is announced as above with preferred embodiment above, so it is not intended to limiting the invention, and all take equally is replaced
