Specific embodiment

Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.Following examples are only used for more Product of the present utility model is clearly demonstrated, therefore is intended only as example, and protection of the present utility model can not be limited with this Scope.

Embodiment：

As shown in Figure 1 and Figure 2, this utility model provides a kind of solar energy lunch box, including box body, and the box body includes protecting Warm box 2 and the base 1 for supporting incubation chamber 2 being arranged on below the incubation chamber 2, the incubation chamber 2 is by outer glass pipe 21 and inner glass tube 22 constitute double-layer glass structure, form vacuum interlayer between the outer glass pipe 21 and inner glass tube 22 24, the outer surface of the inner glass tube 22 is coated with solar selectively absorbing coating 23, the outer glass pipe 21 and inner glass tube The spring supporting 25 for fixing inner glass tube 22 is provided between 22, the bottom of the inner glass tube 22 is provided with getter 26, institute The bottom for stating outer glass pipe 21 is provided with protective cap 27；

Incubation chamber 2 in the present embodiment is heated and is incubated in the case where there is the sun to food, the He of inner glass tube 22 Outer glass pipe 21 has high solar transmission, and fine vacuum is pumped between inner and outer pipe, this almost without gas between tube wall Under state, its convection current heat waste is negligible, only radiation heat loss.When sunlight is mapped to interior glass through the tube wall of outer glass pipe 21 On the solar selectively absorbing coating 23 of the outer surface of pipe 22, convert light into and heat the food in inner glass tube 22 for heat.

Vacuum interlayer 24 in the present embodiment not only can protect solar selectively absorbing coating 23, the work being also incubated With；Solar selectively absorbing coating 23 has the coating of high solar absorptance and low transmitting ratio, absorbs solar radiation simultaneously Solar energy is converted into electric energy；Spring supporting 25 is used for supporting the round end position of inner glass tube 22, it is to avoid inner glass tube 22 and outer glass Glass pipe 21 is contacted；Getter 26 has the effect of air-breathing, and it absorbs the residual gas of vacuum interlayer 24 after evapotranspiring, to improve And the vacuum of holding vacuum interlayer 24；Protective cap 27 is protecting the exhaust nozzle of evacuation rear enclosed.

The box body top is provided with the lid 3 being adapted with the mouth of pipe size of outer glass pipe 22；It is additionally provided with the box body Handle 4, the handle 4 includes being set in the upper lasso and lower lasso of cartridge outer surface, and two ends are connected to lasso With the Handheld Division of the arc on lower lasso, the interior diameter of upper lasso is more than lower lasso interior diameter；Outside the box body generally upper end Diameter is big, the truncated cone-shaped structure that lower end overall diameter is little.

Upper lasso and lower lasso in the present embodiment is used to for handle 4 to be fixed on box body, the convenience of handle 4 of box surface People carry solar energy lunch box.

The solar energy lunch box is highly 250mm.

The external diameter of the cassette upper end is 125mm, internal diameter is 104mm, and the height of the box body is 200mm.

The wall thickness of the outer glass pipe 21 and inner glass tube 22 is 3mm.

The outer glass pipe 22 and inner glass tube 22 are made using the material of Pyrex 3.3.Because glass is fragile article, Adopt Pyrex 3.3 and its thickness is for 3mm, the hardness and intensity of inner glass tube 22 and outer glass pipe 21 is increased, to reach The effect of shatter-resistant.

The box body is integrally formed.

The temperature of the Nausea drying in the sun of the incubation chamber 2 in the present embodiment can reach 270 degree or so, on food lid is filled In the case of lid, sunlight lower ten minutes or so is placed, temperature can rise to 70 degree or so, it can clearly be seen that steam emits Go out, quickly food can be heated.

This utility model gives solar energy lunch box using the heat absorption principle in the sun of solar selectively absorbing coating 23 In food heating, food is incubated using vacuum interlayer 24, mainly solve student, peasant and outwork person in band meal When the problem of hot lunch can be able to eat in the case where there is the sun.

Finally it should be noted that：Above example only to illustrate the technical solution of the utility model, rather than a limitation； Although being described in detail to this utility model with reference to foregoing embodiments, one of ordinary skill in the art should manage Solution：Its technical scheme still described in foregoing embodiments is modified, either to which part or all technical characteristic Carry out equivalent；And these are changed or are replaced, the essence disengaging this utility model for not making appropriate technical solution is respectively implemented The scope of example technical scheme, it all should cover in the middle of the scope of claim of the present utility model and description.
