As shown in fig. 1, the sunlight collected by the bent reflection plate 20 is located above the inner side. In one embodiment, the reflective plate 20 is an aluminum plate, and the inner side of the reflective plate 20 is provided with a smooth surface; the reflective plate 20 directly serves as a light reflective layer. In another embodiment, the inner side of the reflective plate 20 is provided with a reflective film for refracting sunlight; the sunlight is reflected by other structures, and thus the material of the reflection plate 20 may be selected from other kinds, such as plastic; at this time, the reflective plate 20 is used as a structure for bearing the emitting film, and a hollow design can be performed to reduce the weight. The reflecting plate 20 can be formed by splicing the left and right petals or can be directly formed into a whole arc.

In one embodiment, the ejector rod 11 comprises two round pipes nested with each other, the two round pipes are connected through threads, so that the overall length and orientation of the two combined pipes are limited through rotation, and the thread transmission needs certain self-locking, namely, force in the vertical direction is counteracted, and the requirement that the height can be changed only through rotation is ensured. In another embodiment, the top rod 11 includes a base and a supporting plate, the base is sleeved on the support 10 in a disc shape and keeps a degree of freedom of rotation, and the supporting plate is in a U-shaped channel steel structure and is used for connecting the reflecting plate 20 and adjusting the inclination degree of the reflecting plate 20. In still another embodiment, the height of the reflecting plate 20 is adjusted by the supporting frame 10, and then the supporting frame 10 is manually rotated to change the whole reflecting plate.

The heating tube 30 is hollow tube-shaped, the head end and the tail end of the heating tube 30 are connected to the reflecting plate 20 through the connecting rod 31, the middle section of the heating tube 30 receives the sunlight reflected by the reflecting plate 20, the middle section of the heating tube 30 is provided with a heat absorbing layer, and the middle section of the heating tube 30 is black as the heating tube 30 is provided with the heat absorbing layer. In fig. 1, the rod 31 may be elongated, the rod 31 is located at the middle position of the reflection plate 20, and the rod 31 further includes two collars.

The food rack 40 has a strip-shaped structure with an upper side opened to form a storage space, the size of the food rack 40 is smaller than that of the heating tube 30, so that the food rack 40 can be inserted into the heating tube 30, and a handle 43 is arranged at one end of the food rack 40.

The length of the structure of the food rack 40 for placing food is less than the length of the heating tube 30, the head of the food rack 40 is one end extending into the heating tube 30, the head of the food rack 40 is provided with a first baffle 41 to prevent food from accidentally falling, and the tail of the food rack 40 is provided with a second baffle 42 for covering the entrance of the heating tube 30. In fig. 1, it can be seen that after the food rack 40 is inserted into the heat-generating pipes 30, the second baffle 42 blocks the only entrance of the heat-generating pipes 30 to achieve the heat preservation effect. In order to enhance the adhesion between the second baffle 42 and the heat-generating tube 30, a rubber pad or a ring of annular skirt capable of wrapping the inlet of the heat-generating tube 30 is disposed on one side of the second baffle 42.

As shown in fig. 2, the bottom arc of the food rack 40 is equal to the inner arc of the heating tube 30, and at this time, the outer side of the food rack 40 is in full contact with the inner side of the heating tube 30, so that the food rack 40 is not easy to shake and has good stability.
