The bottom plate 11, the side plate 111 and/or the cover side plate 121 and the cover plate 12 form a box-shaped space; the cover side plate 121 and/or the bottom plate side plate 111 are provided with two or more rows of card slots 113; The upper end and/or the lower end are provided with a blocking lever, and the blocking lever can be inserted into the corresponding slot 113 for fixing the rotation angle of the cover 12. This configuration also enables the above-described bracket 13 to be manually fixed by the rotation angle of the cover 12 by three connection means.

Another specific manual fixing method is as follows: The bracket 13 is provided with a telescopic device, and the bracket can be adjusted. The length of the telescopic device is provided with a locking device for locking the length of the bracket 13 after telescoping; by adjusting the length of the bracket 13, the angle between the cover plate 12 and the bottom plate 11 can be adjusted. This configuration also enables manual fixing of the rotation angle of the cover plate 12.

The solar cooker of the present invention, in order to facilitate carrying and use, has a base 1 which is generally elongated and constitutes two important parts of the base 1 and a cover 12 which is of course elongated. However, the disadvantage of the elongated base 1 is that the placement is unstable and it is easy to dump. Therefore, the solar energy cooker of the present invention is provided with a support plate for a more stable placement of the base.

Referring to Figures 6 and 7, the bottom plate 11 is elongated, and a support plate 14 is disposed below the bottom plate 11, and at least one end of the support plate 14 is away from the long side of the bottom plate 11. As long as one end of the support plate 14 is away from the long side of the bottom plate 11, the landing area of the bottom plate 11 can be increased to enhance the stability of its placement. For the purpose of movement, a roller can be provided below the bottom plate 11.

In order to achieve a stable placement of the base 1 and to facilitate carrying and use, a fixing hole 140 is disposed on the bottom plate 11 and the support plate 14 , and the rotating bolt 142 is connected to the bottom plate 11 and the support plate 14 through the fixing hole 140 , and simultaneously The support plate 14 is rotatable about the rotating bolt 142; the support plate 14 is preferably also elongated; in the working state, the support plate 14 is rotated until at least one end thereof is away from the long side of the bottom plate 11; when in the non-working state, the support plate 14 is rotated to the same The long sides are parallel to the long sides of the bottom plate 11. This structure not only allows the solar cooker to be stably placed in the working state, but also facilitates carrying in a non-working state.

Referring to Fig. 8 and Fig. 9, a schematic structural view of the fifth embodiment of the base provided with the support plate may be provided with a reinforcing groove 144. The cross section of the reinforcing groove 144 may be V-shaped, trapezoidal, U-shaped or curved. By providing a reinforcing groove, the support strength of the support plate 14 can be increased, and the cookware can be placed more stable when it is in working condition.

A spring 143 is attached to the rotating bolt 142, and the spring 143 is sleeved on the rotating bolt and disposed above the bottom plate 11. Due to the elastic force of the spring 143, the structure between the support plate 14 and the bottom plate 11 in the free state can be made tighter, the rotation is less likely to occur, and the angular position after the rotation of the two can be better fixed; in the rotating state, the support plate is pulled. 14 , the support plate 14 is away from the bottom plate 11 , so that the spring 143 is further compressed, a certain distance is generated between the support plate 14 and the bottom plate 11 , and then after the support plate 14 is rotated to a suitable angle, after the support plate 14 is released, Under the elastic force of the spring 143, the bottom plate 11 is again tightly fitted, and the spring 143 is disposed. When rotating, the scratch caused by the relative sliding friction between the support plate 14 and the bottom plate 11 can be avoided, and the bottom plate 11 can be prevented from being damaged. In order to facilitate carrying the aforementioned solar cooker, a groove 141 is provided below the bottom plate 1 1 , and the groove 141 is disposed along the length direction of the bottom plate 11 , and the support plate 14 is placed in the groove 141 in a non-operating state. This makes the solar cooker more portable and aesthetically pleasing.

Referring to Fig. 10, it is a schematic structural view of a base embodiment 6 provided with a support plate. In the figure, the support plates 14 are in multiple groups, and are respectively arranged on the bottom plate 1 1 in an interval, so that the support is more stable.

In the working state, the fixing of the rotation angle between the support plate 14 and the bottom plate 11 is very important, and the placement angle is preferably 90 degrees, and the support effect is the best. Referring to Fig. 11, is a schematic structural view of a base embodiment 7 provided with a support plate. In order to accurately adjust the rotation angle, a baffle 145 is disposed on a side of one end of the support plate 14, and/or the other end of the support plate 14 is provided. A baffle 145 is also provided on the other side of the support; that is, a baffle 145 is provided on the opposite sides of the two opposite sides of the support plate 14. The flapper 145 serves to prevent excessive rotation of the support plate 14. The baffle 145 has two functions. One is that when the support plate 14 is rotated from the non-operating state to the working state, the baffle 145 is disposed such that the longer side of the support plate 14 is rotated to form an angle with the bottom plate 11. At 90 degrees, it is blocked by the baffle and can no longer be rotated; when the support plate 14 is rotated from the working state to the non-working state, when the longer side thereof coincides with the longer side of the bottom plate 11, the support plate 14 is blocked. Can't rotate anymore. The position of the baffle 145 on the support plate 14 is: when the longer side of the support plate 14 and the longer side of the bottom plate 11 are at an angle of 90 degrees, one end of the baffle 145 just abuts against the longer side of the bottom plate 11. On the side, when the longer side of the support plate 14 is parallel to the longer side of the bottom plate 11, the side of the shutter 145 just catches the longer side of the bottom plate 11.

By providing a sundial calibrator, the solar cooker of the invention can adjust the reflector to a proper orientation and pitch angle by manual and accurate, thereby improving the utilization rate and use efficiency of solar cookers for sunlight. The corona calibrator is used as a reference for manual adjustment.

Referring to FIG. 12, FIG. 13 and FIG. 14, a corona calibrator embodiment 1 of the present invention includes: a projection bottom plate 44 on which a projection calibration area 452 is disposed; and a projection body 41 disposed above the projection calibration area 452. The orthographic projection of the projection 41 completely falls within the projection calibration area 452. Specifically, the projection bottom plate 44 is square or circular, and is used for setting the projection calibration area 452. The area of the projection calibration area 452 is larger than the projection surface of the projection body 41. Therefore, it is possible for the orthographic projection of the projection body 41 to be fully projected. Projected within calibration area 452. Obviously, the projection of the projection body 41 is all thrown into the projection calibration area 452, and the projection body 41 is required to be above the projection calibration area, preferably directly above, even if it is not directly above, its position cannot be too much deviation, otherwise It is impossible to cast all of its projections into the projection calibration area 452. Inside. Meanwhile, above or directly above, it is meant that the projection 41 is located above the projection calibration area 452 with a certain distance from the projection calibration area.

The corona calibrator of the present invention is mounted on a solar cooker, and the orientation of the projection bottom plate 44 is consistent with the orientation when the reflector is opened; if the reflector is two curved reflectors that are symmetrical about an axis, the calibrator is preferably mounted. Positioned on the axis, or it is projected on the axis; if the reflector is a piece, the shape is an arc symmetrical in the central axis, the preferred position of the corona aligner is mounted on the central axis, or its orthographic projection On the central axis; if the reflective surface of the reflector is hemispherical, the preferred position of the corona aligner is mounted at an axis that passes through the center of the hemisphere. There should be no other parts that block the sun above the installation position of the sundial. In use, first adjust the position and angle of the solar cooker reflector, so that the projection of the projection 41 falls into the center of the projection calibration area 452; when the sun illumination angle changes over time, the projection portion of the projection 41 or When all the projection calibration area 452 is removed, the position and angle of the reflector are adjusted, and then the projection of the projection 41 falls into the center of the projection calibration area 452; during the whole use of the solar cooker, the projection is continuously adjusted to make the projection The projection of the body 41 falls within the area of the projection calibration zone 452 for as long as possible. This ensures that the reflector can reflect most of the sunlight and achieve full use of solar energy.

Referring to Fig. 15, a schematic structural view of a second embodiment of the corona calibrator of the present invention is shown. As is apparent from the figure, the second embodiment has the same configuration as that of the first embodiment except that the structure of the projection body 41 is changed. The center of the projection body 41 of the second embodiment has a light transmission hole 411. In use, the spot of sunlight passing through the light transmission hole 411 needs to fall as far as possible into the projection calibration area. This spot is equivalent to the projection of the projection in the embodiment.
