Example 1: the heat preservation table in this scheme, as shown in fig. 1, including desktop 9, stabilizer blade 1, heat preservation lid 2 and rotary driving device, stabilizer blade 1 is connected in desktop 9 below, and integrated into one piece has the basin that is used for installing heat preservation lid 2 on the desktop 9, and the basin is the annular, and the basin width is greater than the wall thickness that covers heat preservation lid 2. The surface of the heat preservation cover 2 is provided with heat insulation materials such as aerogel felts or vacuum plates and the like as heat insulation layers, the heat preservation cover 2 is arranged in the water tank, the inner wall of the heat preservation cover 2 is provided with a plurality of self-heating bags 13, and the self-heating belts are uniformly distributed on the inner wall of the heat preservation cover 2. The bottom of the self-heating belt is arranged in the water tank, so that the self-heating bag 13 can absorb water conveniently.

The rotary driving device is a motor 3, a gear 4 is installed at the output end of the motor 3, an installation layer is integrally formed in the heat preservation cover 2, the motor 3 is fixed on the installation layer, and an inner gear ring 6 meshed with the gear 4 is rotatably connected to the installation layer. An annular connecting piece 8 is integrally formed at the lower part of the inner gear ring 6, a plurality of pressing pieces 14 for pressing the self-heating bags 13 are rotatably connected to the connecting piece 8, and the pressing pieces 14 are cylindrical. As shown in fig. 2, the pressing member 14 comes into contact with the self-heating pack 13 and can deform the heating pack. The heat preservation cover 2 is internally riveted with a waterproof cover 7 to prevent water 17 from splashing into the rice 5 when the pressing piece 14 acts on the self-heating bag 13.

The self-heating bag 13 is filled with heat preservation powder 10 or a mixture consisting of the heat preservation powder 10 and heat preservation additives 11, wherein the heat preservation powder 10 consists of 10 parts of baked diatomite, 50 parts of iron powder, 15 parts of aluminum powder, 5 parts of coke powder, 5 parts of activated carbon and 5 parts of salt, and the heat preservation additives 11 consist of 100 parts of quicklime and 50 parts of sodium carbonate. The inner gear ring 6 can be replaced by an outer gear ring, but the use of the outer gear ring can cause the volume of the self-heating bag 13 to be too large, and the cost is increased. The motor 3 and the inner gear ring 6 can be arranged outside the heat preservation cover 2, the arrangement can achieve the same effect, but the appearance is not attractive, and the operation is not performed when the heat insulation coating is installed. The self-heating can also be unevenly distributed on the inner wall of the heat preservation cover 2, as long as the two symmetrical self-heating belts are symmetrically arranged about the central line of the heat preservation cover 2 so that the device is stressed simultaneously when in work, namely the inner wall of the heat preservation cover 2 is subjected to two opposite and equal acting forces, and the two acting forces are mutually offset to prevent the heat preservation cover 2 from vibrating.

The working principle is as follows: the optimal temperature for keeping the meal is 60 deg.C, because the bacteria growth can be inhibited at 60 deg.C, the heat-insulating powder 10 is added into the self-heating bag 13, the meal 5 is placed in the ring enclosed by the water tank, and the heat-insulating cover 2 is covered on the meal 5. The motor 3 is started, the motor 3 drives the gear 4 to rotate, the gear 4 drives the inner gear ring 6 to rotate, and the connecting piece 8 on the inner gear ring 6 drives the pressing piece 14 to extrude the self-heating belt. Since the pressing members 14 are cylindrical, the distance between each pressing member 14 and the self-heating bag 13 is constantly changed during the rotation of the connecting member 8, and therefore the pressing members 14 intermittently press the self-heating bags 13, so that the heat-insulating powder 10 in the self-heating belt is pressed to start heating. In the process, the heat preservation cover 2 is arranged in the water tank, so that the heat preservation cover 2 is prevented from moving when being pressed, the pressing piece 14 which is rotatably connected to the connecting piece 8 rotates in the process of pressing the self-heating bag, the friction force between the pressing piece 14 and the self-heating bag 13 is dynamic friction force, and the abrasion of the self-heating bag 13 is reduced. The heat preservation powder 10 heats up to 60 ℃, and the heat emitted by the heat preservation powder 10 heats the surrounding air, so that the meal 5 is in the air with higher temperature, and the meal 5 is kept at the temperature for a long time. People going home at night can eat hot meal 5 only by uncovering the heat preservation cover 2.

When the heating temperature of the meal is above 100 ℃ and heating and heat preservation are needed, water 17 is added into the water tank, and heat preservation powder 10 and heat preservation additives 11 are added into the self-heating bag 13, so that the self-heating bag 13 is positioned in the water 17. The meal 5 is put in a ring surrounded by the water tank, and the heat preservation cover 2 is covered on the meal 5. The motor 3 is started, the motor 3 drives the gear 4 to rotate, the gear 4 drives the inner gear ring 6 to rotate, and the connecting piece 8 on the inner gear ring 6 drives the pressing piece 14 to extrude the self-heating belt. Since the pressing members 14 are cylindrical, the distance between each pressing member 14 and the self-heating bag 13 is constantly changed during the rotation of the connecting member 8, so that the pressing members 14 intermittently press the self-heating bags 13, and the heat-insulating powder 10 and the heat-insulating additive 11 in the self-heating belt are uniformly mixed. The self-heating bag 13 is pressed and deformed at a position where the distance between the pressing piece 14 and the self-heating bag 13 is small, and the self-heating belt is restored and deformed at a position where the distance between the pressing piece 14 and the self-heating bag 13 is large. When the materials in the self-heating belt are pressed, the gaps between the materials are reduced, and the sucked water 17 is diffused to the periphery. When the pressing is not performed, the gap between the materials is enlarged, and water absorption is performed. This is repeated, and the water 17 in the water tank gradually enters the self-heating bag 13. Meanwhile, the temperature of the self-heating belt begins to rise, the heat-insulating cover 2 is arranged in the water tank in the process, the heat-insulating cover 2 is prevented from moving when being pressed, the pressing piece 14 which is rotatably connected to the connecting piece 8 rotates when the self-heating belt bag is pressed, the friction force between the pressing piece 14 and the self-heating bag 13 is dynamic friction force, and the abrasion of the self-heating bag 13 is reduced. The heat preservation powder 10 heats up to 120 ℃, and the heat emitted by the heat preservation powder 10 heats the surrounding air, so that the meal 5 is in the air with higher temperature, and the meal 5 is kept at the temperature for a long time. Because the heating temperature is only 120 ℃, the duration can be controlled within 20 minutes by adjusting the time for covering the heat preservation cover 2. People do not need to worry about that the food 5 is burnt when people forget to turn off the fire when heating the food 5, and the food 5 can be kept warm after being heated.

Example 2: on the basis of embodiment 1, as shown in fig. 3, a plurality of motors 3b are fixed on the fixing layer, the output ends of the motors 3b are connected with a first connecting rod 16, one end of a second connecting rod 15 is hinged on the first connecting rod 16, and a pressing piece 14b is hinged on the other end of the second connecting rod 15. A slide way 18 is integrally formed on the heat preservation cover 2b, and the pressing piece 14b is installed in the slide way 18. The self-heating belt is located on a moving path of the pressing member 14b while the self-heating belt is located in the water tank.

The clamping groove is matched with the clamping piece, so that the heat preservation cover 2b is prevented from being separated from the water tank due to the fact that the pressing piece 14b is subjected to upward acting force in the working process.

The working principle is as follows: when the pressing device is used, the motor 3b is started, the first connecting rod 16 starts to rotate under the driving of the motor 3b, the second connecting rod 15 swings under the driving of the first connecting rod 16, and the pressing piece 14b slides back and forth in the slide way 18 under the driving of the second connecting rod 15. The pressing piece 14b which slides back and forth intermittently presses the pressing piece 14b in the slideway 18, so that the heat preservation powder 10 in the self-heating belt is pressed and mixed evenly and starts to generate heat. When heating is needed, intermittent pressing of the pressing piece 14b can also enable the heat preservation flour 10 and the heat preservation additive 11 to be uniformly mixed, when the pressing piece 14b presses the self-heating bag 13b, water 17 in the material can diffuse to the periphery, when the pressing piece 14b is not in contact with the self-heating bag 13b, the material is not subjected to pressure, a part of deformation begins to recover, and the water 17 is sucked into gaps between the materials. At this time, the self-heating bag 13b starts to generate heat, and heats the food in the thermal cover 2 b.

The heat preservation powder 10 in the self-heating belt is pressed and mixed evenly and starts to generate heat. When heating is needed, the intermittent pressing of the pressing piece 14c can also enable the heat preservation flour 10 and the heat preservation additive 11 to be uniformly mixed, when the pressing piece 14c presses the self-heating bag 13c, water 17 in the material can diffuse to the periphery, when the pressing piece 14c is not in contact with the self-heating bag 13c, the material is not subjected to pressure, a part of deformation begins to recover, and the water 17 is sucked into gaps between the materials. At this time, the self-heating bag 13c starts to generate heat and heat the food in the thermal insulation cover 2 c.
