The grating type reflector 2 is arranged on the shell 1, the longitudinal slide rail 10 is fixed on the shell 1, the bottom ends of the upper and lower telescopic supporting rods 12 are connected with the transverse slide rail 3 through the sliding blocks and can transversely move along the transverse slide rail 3, and the transverse slide rail 3 can longitudinally move along the longitudinal slide rail 10. The top of the upper and lower telescopic supporting rods 12 is rotatably connected with the first part of the vacuum tube support 4 through a rotating shaft, the middle ends of the upper and lower telescopic supporting rods 12 are connected with the first end of the telescopic supporting rod 7 through a rotating shaft, and the second end of the telescopic supporting rod 7 is connected with the second part of the vacuum tube support frame 4 through a rotating shaft, so that the vacuum tube support 4 can rotate around the supporting rods 12.

The automatic sun tracking device 11 is fixed on the upper and lower telescopic supporting rods 12 and used for detecting the azimuth angle of the sun, and the automatic sun tracking device 11 can adopt a device used for detecting the position of the sun in the prior art.

The vacuum tube 5 is fixed on the vacuum tube holder 4. The vacuum tube 5 may have two openings: the opening 51 at the top and the opening 52 at the bottom can also only have the opening 51 at the top, the cooker inner cylinder 55 is arranged in the vacuum tube 5, and the size of the cooker inner cylinder 55 can be just smaller than that of the vacuum tube 5, so that after the cooker inner cylinder 55 is inserted into the vacuum tube 5, the cooker inner cylinder 55 can be tightly attached to the inner wall of the vacuum tube 5, thereby facilitating the heat conduction of the vacuum tube 5 to the cooker inner cylinder 55. The cooktop inner barrel 55 can have two openings: top opening 551 and bottom opening 552, but may have only one opening: the vacuum tube 5 further comprises a cover which is matched with the opening 52 at the lower end and is installed by matching threads with the opening 52 at the lower end, and the mode adjusting valve 9 is arranged on the surface of the heat preservation cover 553. The stove inner cylinder 55 can be made of stainless steel, aluminum alloy and other metal materials. The vacuum tube 5 may be made of diamond or the like which has good transparency, high temperature resistance and is not brittle.

Since the vacuum tube 5 has two openings, the vacuum tube 5 can be cleaned more conveniently and thoroughly. Food and the like can be placed in the inner barrel 55 of the cooker for heating, so that the vacuum tube 5 is prevented from being polluted by the food and the like which are directly contacted with the vacuum tube 5. The stove inner cylinder 55 adopts two openings, so that the stove inner cylinder 55 is more convenient and thorough to clean.

The vacuum tube 5 can be provided with a heat absorbing layer on the outer wall of the inner cooker cylinder 55 instead of a heat absorbing layer, so that the heating effect of the inner cooker cylinder 55 is not influenced by the gap between the inner cooker cylinder 55 and the vacuum tube 5. The shell 1 can be a flat plate type shell and can be made of soft materials such as iron sheets and polyethylene, when the shell is not needed to be used, the shell 1 can be rolled up and stored in a long box together with the vacuum tube 5, and the shell is convenient to carry. The housing 1 can be folded into a box, so that the vacuum tube 5 and other components can be accommodated in the box, and the carrying is more convenient, as shown in fig. 6. The focusing device may further comprise a rotating device (not shown) arranged at the bottom of the housing 1, which can drive the housing 1 together with the reflector 2 to rotate in a large range, for example, 360 ° in space. The rotating means may be the same as or similar to the mechanism for driving the vacuum tube holder to rotate, and of course, the person skilled in the art can realize the rotation of the housing 1 by many existing rotating mechanisms.

The focusing device can be realized by other structures, and a person skilled in the art can realize the focusing device by a plurality of existing driving mechanisms as long as the position of the vacuum tube 5 can be adjusted.

Since the position of the sun changes continuously during the day, in order to ensure that the light reflected by the reflector 2 is focused on the vacuum tube 5, the position of the reflector 2 and the position of the vacuum tube 5 need to be changed accordingly.

When the automatic sun tracking device 11 detects that the sun moves from the first direction to the second direction, the rotating device can drive the shell 1 to rotate towards the second direction, so that the reflector 2 faces the sun in the positive direction; meanwhile, the telescopic of the upper and lower telescopic supporting rods 12 can be adjusted, so that the height of the vacuum tube support 4 is adjusted, the angle of the vacuum tube support 4 is rotated, the transverse slide rail 3 longitudinally moves along the longitudinal slide rail 10, and the upper and lower telescopic supporting rods 12 transversely slide along the transverse slide rail 3, so that the vacuum tube 5 is positioned at or close to the focus of the reflector 2, and the light energy can be maximally utilized. The method of adjusting the reflector 2 by detecting the azimuth angle of the sun may employ an existing method, such as a method of operating an automatic sun tracking device disclosed in a solar cooker under publication No. 102589151 a. Of course, the height of the upper and lower telescopic supporting rods 12 can be adjusted manually, for example, the height of the upper and lower telescopic supporting rods 12 can be adjusted manually, and then the height of the upper and lower telescopic supporting rods 12 can be fixed by the locking device 8, and the angle of the rotating vacuum tube support 4 can also be adjusted manually.

The solar cooker has a simple structure, is convenient to disassemble, and is beneficial to saving storage space.

The mode adjustment valve 9 is used to adjust a cooking mode when the vacuum tube 5 is operated, and may have a plurality of different cooking function gears, such as a grill mode, a rice cooking mode, a porridge cooking mode, and the like, and when the mode adjustment valve 9 is adjusted to the different cooking modes, the vacuum tube 5 is operated with different cooking parameters, such as different temperatures, heating times, humidity, or pressure, and the like. In some embodiments, the focusing device can adjust the position of the vacuum tube according to the temperature or heating time of the vacuum tube, so as to adjust the parameters of the vacuum tube 5, such as temperature, heating time, humidity, and the like.

For example, a temperature sensor is arranged in the vacuum tube 5, and when the temperature in the vacuum tube 5 is higher than a set temperature (for example, the temperature in a barbecue mode is higher, and the temperature in a rice and porridge cooking mode is lower), the position of the vacuum tube 5 can be adjusted, for example, the height or the rotation angle of the vacuum tube bracket 4 is adjusted, so that the vacuum tube can deviate or be far away from the focus of the reflector 2, and the heating power of the vacuum tube 5 is reduced; or the rotating device adjusts the orientation of the shell 1 to make the reflector 2 move in the direction back to the sun, so that the light energy collected by the reflector 2 is reduced, and even if the vacuum tube 5 is still at the focus of the reflector 2, the heating power of the vacuum tube 5 is also reduced. In addition, the solar cooker may include a timer, and when the timer detects that the heating time of the vacuum tube 5 exceeds a set time, the position of the vacuum tube 5 is adjusted to deviate or be far away from the focal point of the reflector 2, so as to reduce the heating power of the vacuum tube 5; similarly, the heating power of the vacuum tube 5 can be reduced by adjusting the orientation of the housing 1 by the rotating means.

As shown in fig. 4 and 5, the mode adjustment valve 9 of an embodiment, for matching with the top opening of the vacuum tube, includes a valve main body 92 and a rotary plate 91, a rotary plate head 95 may be disposed on the rotary plate 91, the rotary plate 91 is rotatably connected to the valve main body 92 through a rotary shaft 96, a plurality of pressure relief holes with different pressure relief pressure thresholds are disposed on the valve main body 92, as shown in fig. 4, a first pressure relief hole 93 which is not covered by the rotary plate 91 and a second pressure relief hole 94 which is covered by the rotary plate 91, each pressure relief hole has a pressure relief valve 97, and the pressure relief threshold of the pressure relief hole may be determined by the respective pressure relief valve 97. The spiral piece 91 has a notch, and when the spiral piece 91 rotates on the valve main body 92 at any angle, a part (for example, only one) of the pressure relief holes is below the notch, and the rest of the pressure relief holes are covered by the spiral piece 91, and air cannot flow out from the covered pressure relief holes, for example, the first pressure relief hole 93 is below the notch of the spiral piece 91, and the second pressure relief hole 94 is covered by the spiral piece 91, as shown in fig. 4. Therefore, when the rotary plate 91 is at different positions, different pressure relief holes are not covered, so that different pressure relief thresholds are provided, and when the vacuum tube 5 is used for cooking, the mode adjustment valve 9 is covered on the top opening of the vacuum tube 5, so that the pressure in the vacuum tube can be adjusted during cooking.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details.
