Detailed Description

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used in the description of the applications herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having" and any variations thereof in the description and claims of the present application and in the description of the figures above are intended to cover non-exclusive inclusions. The terms first, second and the like in the description and in the claims or in the above-described figures, are used for distinguishing between different objects and not necessarily for describing a sequential or chronological order.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

In order to better understand the technical solutions of the present application, the following description will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings.

Referring to fig. 1 to 3, the utility model provides a solar cooker, which comprises a glass shell 1, a metal liner 2, a metal sealing ring 5, a cooker body 3 and a cooker cover 4;

the glass shell 1 and the metal liner 2 are tubular structures with one open end, a positioning bracket 11 is arranged in the glass shell 1, and the bracket can be integrally formed with the metal liner 2 or can be a bracket structure, such as a ring bracket, placed in the formed glass shell 1. The metal liner 2 is arranged inside the glass shell 1, and one inward end of the glass shell 1 is fixed on the positioning bracket 11; the open end of the glass shell 1 is welded with the bottom end of the metal sealing ring 5, the metal sealing ring 5 and the open end of the metal liner 2 are connected together in a hot-melt welding mode to form a vacuum tube structure with one open end, namely a vacuum layer is arranged between the glass shell 1 and the metal liner 2; when the vacuum tube structure is manufactured, an exhaust port 6 can be reserved at the tail part of the glass shell 1, then after the glass shell 1 and the metal liner 2 are welded by hot melting, a certain vacuum degree is formed between the glass shell 1 and the metal liner 2 in a vacuumizing mode through the exhaust port 6, and the exhaust port 6 is sealed. In addition, the metal sealing ring 5 can be welded with the metal liner 2 first, and then the bottom end of the metal sealing ring 5 is welded with the open end of the glass shell 1, so that the tightness of connection is ensured after the connection. Of course, before welding, the outer layer of the metal liner 2 is covered with a light-heat absorbing film layer, and the sunlight irradiates the light-heat absorbing film layer, and then transfers heat to the metal liner 2 to convert solar energy into heat energy.

The pot body 3 is tightly arranged in the metal liner 2 and can be detached, namely, the pot body 3 can be inserted or withdrawn, and the pot cover 4 can be detached to cover the opening of the vacuum tube structure. The fact that the cooker body 3 is tightly attached to the inside of the metal inner container 2 means that after the cooker body 3 is placed in, the outer surface of the cooker body 3 is in butt joint with the inner surface of the metal inner container 2, so that the contact area of the cooker body 3 and the inner surface of the metal inner container 2 is large under the condition that the outer surface of the cooker body 3 is matched with the inner surface of the metal inner container 2, quick conduction of heat energy is facilitated, and the cooker is used for heating water, food and the like needing to be heated in the cooker body 3.

The pot body 3 is a semi-closed pot body 3, one end of the pot body 3 is fixedly connected with the inner side of the pot cover 4, and the structure is shown in fig. 2. Of course, the pan body 3 may also have a tubular structure as shown in fig. 3.

Wherein, the pot cover 4 is provided with a thermometer 41, and a probe 411 of the thermometer 41 is positioned at the inner side of the pot body. The thermometer 41 is provided, so that a user can know the temperature in the pot body 3 at any time to adjust the cooking strategy.

The metal liner is made of metal or alloy material, for example, the metal liner 2 is made of one of copper, iron, aluminum or stainless steel.
