Detailed description of the invention
Now by reference to the accompanying drawings elliptical cavity formula vacuum flask and heat preserving method thereof are described in further detail.
As shown in Figure 1, Figure 2 and shown in Fig. 3, elliptical cavity formula vacuum flask comprises stainless steel inner container 1, ovallized column body case 2, strip convex lens 3, the adiabatic fixture 4 of plastics, opening capping 5, bottle cap 6 and vacuum flask hand 9.It is inner that stainless steel inner container 1 is placed in shell 2, and described shell 2 is the cylinder of a hollow, and the cross sectional shape of cylinder is oval, and the central axis of stainless steel inner container 1 overlaps with the first focal line of ovallized column body case 2; Ovallized column body case 2 sidewall is provided with longitudinal opening, and the cross section of opening is arranged at the elliptical head near the second focal line, is provided with strip convex lens 3 at described aperture position.
Described stainless steel inner container 1 is the cylindric inner bag be made up of stainless steel, its outer surface light absorber coatings, and to 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 bottom stainless steel inner container 1, for fixing stainless steel inner container 1; The bottle cap 6 of stainless steel inner container 1 is connected by the bottle sealing of helix with stainless steel inner container 1; Adiabatic fixture 4 material is plastics, both can stop thermal loss, and can fix stainless steel inner container 1 again.
Described ovallized column body case 2 has an opening, and ovallized column body case 2 is except aperture position, and inner surface all applies silver coating 7, stops thermal loss and sunlight reflection.Fill heat-preservation cotton 8 between the inner surface of ovallized column body case 2 and outer surface, stop thermal loss further.Opening is used for entering of sunray, and opening is larger, and the light that can enter ovallized column body case 2 inside is more, and meanwhile, the heat lost by opening is also more, and the size of opening determines the heat insulation effect of vacuum flask;
Ovallized column body case 2 inside is evacuated, and stops thermal convection current.
Strip convex lens 3 are arranged on the aperture position of ovallized column body case 2, and strip convex lens 3 are tightly connected with the opening part of ovallized column body case 2.
Ovallized column body case 2 is connected 9 with vacuum flask hand, to facilitate carrying of vacuum flask.
Vacuum flask hand is fixed on 9 skins in ovallized column body case 2, and hand comprises skin and internal layer 9, outer for being fixed on the large rectangle frame in ovallized column body case 2; Internal layer comprises an axis, and axes normal is fixed between the bottom and upper segment of outer field large rectangle frame, and little rectangle frame is arranged around axis.Hand can rotate 9 internal layers and pass through to reverse the nut be arranged on above axis and be fixed on certain position, so that strip convex lens 3 are just to the sun.
Opening capping 5 inner surface is silver-plated, when elliptical cavity formula vacuum flask leaves unused, opening capping 5 can be covered on strip convex lens 3 outside.
The heat preserving method of elliptical cavity formula vacuum flask of the present invention, comprises the following steps:
(1) open field in the wild, by the strip convex lens of elliptical cavity formula vacuum flask opening just to the sun, sunray will focus on the focal position of convex lens;
(2) because the focus of convex lens overlaps with the second focus of ovallized column body case, the sunshine being gathered in strip concave lens focus position necessarily passes the second focal line of ovallized column body case;
(3) sunshine through ovallized column body case second focal line position arrives the inner surface of ovallized column body case, after primary event, necessarily pass the first focal line of ovallized column body case, the central axis of stainless steel inner container overlaps with the first focal line, so the sunray after focusing on impinges upon on stainless steel inner container, heat stainless steel inner container, stainless steel inner container transfers heat to the article of the inside;
(4) when elliptical cavity formula vacuum flask leaves unused (if night is without the solar time), by opening cap cover outside strip convex lens.
Operation principle labor of the present invention is as follows: ovallized column body case 2 inner surface silver-plated 7, heat-preservation cotton 8 is filled between its inner surface and outer surface, ovallized column body case 2 opening strip convex lens 3 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, fix with the adiabatic fixture 4 of plastics bottom stainless steel inner container 1, stainless steel inner container 1 is placed in by needing the article of insulation, if find, in stainless steel inner container 1, article cool, the strip convex lens 3 of elliptical cavity formula vacuum flask can be faced the sun, first directional light 11 focuses on the second focal line of ovallized column body case 2 through strip convex lens 3, through the sunshine of ovallized column body case 2 second focal line can be radiated at after primary event be placed in vacuum flask first focal line stainless steel inner container 1 on, stainless steel inner container 1 is heated, thus the article in vacuum flask are heated.When the sun is in sky diverse location, by regulating vacuum flask hand to regulate strip convex lens 3 to face the sun all the time the internal layer of 9, thus more sunray is made to enter ovallized column body case 2.
Below announce the present invention as above with preferred embodiment, so it is not intended to limiting the invention, and all technical schemes taking the mode of equivalent replacement or equivalent transformation to obtain, all drop in protection scope of the present invention.
