Abstract

The present invention discloses a portable solar cooker, belonging to the field of solar heat utilization. The solar cooker comprises an upper functional assembly, a lower control assembly and a rotary apparatus which are sequentially connected, wherein the upper functional assembly is configured to reflect sunlight, collect heat in a focusing manner and further heat water or foods, the upper functional assembly is closed to form a box body when being in a non-operative state, and the upper functional assembly is opened when being in an operative state; the lower control assembly is connected with the upper functional assembly, and makes the upper functional assembly be subjected to pitch adjustment; the lower control assembly is connected with the rotary apparatus, and the lower control assembly and the upper functional assembly are driven by the rotary apparatus to rotate so that tracking the sun is realized. The portable solar cooker disclosed by the present invention not only has functions of boiling water and cooking foods, but also has the advantages of facilitating carrying and tracking the sun, and can achieve full utilization of solar energy anytime and anywhere, thereby making the application of the solar energy be fully developed.
