Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 This utility model provides a technical solution: a novel rice cooker 1 with anti-dry-burning function, comprising a rice cooker 1, an inner pot 2 disposed in the middle of the inner side of the rice cooker 1, and a temperature control mechanism for controlling the stability of the rice cooker 1 disposed in the lower end of the inner side of the rice cooker 1. The temperature control mechanism includes a cavity 3, a protrusion 4, a first strong magnet 5, a first contact 6, a limiting block 7, a second strong magnet 8, and a second contact 9. The lower end of the inner side of the rice cooker 1 is provided with a cavity 3, the upper end of the cavity 3 is movably inserted with a protrusion 4, the lower end of the protrusion 4 is fixedly disposed with a first strong magnet 5, the lower end of the first strong magnet 5 is fixedly disposed with a first contact 6, the lower end of the first strong magnet 5 is fixedly disposed in the cavity 3, the lower end of the first strong magnet 5 is fixedly disposed with a limiting block 7, the upper end of the limiting block 7 is movably engaged with a second strong magnet 8, and the upper end of the second strong magnet 8 is fixedly disposed with a second contact 9.

[0020] The electric rice cooker 1 is fixedly provided with a total control switch 10 on one side, and a heating surface is fixedly arranged at the lower end inside the electric rice cooker 1; the total control switch 10 is connected in series between the first contact 6, the second contact 9 and the electric rice cooker 1, that is, when the total control switch 10 is closed, the first contact 6 is in contact with the second contact 9, and the heating surface is powered to enter a heating state; when the heating temperature reaches a threshold value, the convex block 4 transmits heat to the first strong magnet 5, the first strong magnet 5 is weakened to the threshold value by the heat magnetic force, and then the second magnet and the second contact 9 are reset downward under the action of the second spring 13; the first contact 6 is separated from the second contact 9, and at this time, the heating surface can be powered off to prevent dry burning;

[0021] The first spring 11 is arranged between the limiting block 7 and the convex block 4 inside the cavity 3, and when the inner container 2 is not placed into the electric rice cooker, the convex block 4 and the first contact 6 and the second contact 9 are in a separated state by the first spring 11;

[0022] The adjusting block 12 is movably screwed at the lower end inside the cavity 3, the second spring 13 is fixedly arranged between the adjusting block 12 and the second magnet, the upper end of the second spring 13 is fixedly connected with the second magnet, and the lower end of the second spring 13 is fixedly connected with the adjusting block 12; by moving the adjusting block 12 up and down, the initial elastic force of the second spring 13 can be adjusted; when the adjusting block 12 moves downward, the elastic force of the second spring 13 becomes larger, so that when the first strong magnet 5 is heated and the magnetic force is attenuated, the second spring 13 can pull the second contact 9 downward to separate the first contact 6 from the second contact 9 at an earlier time (at a lower separation triggering temperature), and vice versa, so that the separation triggering temperature can be increased, and the rice can be cooked harder to produce pot-brownings according to needs;

[0023] The adjusting block 12 is fixedly provided with a knob 14 at the lower end, and the knob 14 can be conveniently rotated to adjust the position of the adjusting block 12;

[0024] The electric rice cooker 1 is provided with a top cover 15 at the upper end.

[0025] Working principle: when the inner container 2 is put into the electric rice cooker 1, the convex block 4 is pressed down, so that the convex block 4 moves down and contacts the surface of the limiting block 7, and the heating surface contacts the inner container 2 at the same time. At this time, the convex block 4 contacts the limiting block 7, and then under the magnetic force of the first strong magnet 5 and the second strong magnet 8, the second strong magnet and the second contact 9 are attracted and move up, so that the first contact 6 and the second contact 9 are closed. At this time, the heating surface is powered on to heat and cook rice by opening the main switch. Then, when the heating temperature reaches the threshold value, the convex block 4 transmits heat to the first strong magnet 5, the magnetic force of the first strong magnet 5 is weakened to the threshold value, and then the second magnet and the second contact 9 are reset downward under the action of the second spring 13, so that the first contact 6 and the second contact 9 are separated. At this time, the heating surface is powered off to prevent dry burning.

[0026] When the device is used, the initial elastic force of the second spring 13 can be adjusted by the up and down movement of the adjusting block 12. When the adjusting block 12 moves down, the elastic force of the second spring 13 becomes larger. In this way, when the first strong magnet 5 is heated and the magnetic force is attenuated, the second spring 13 can pull the second contact 9 downward to separate the first contact 6 and the second contact 9 at an earlier time (at a lower separation trigger temperature). Conversely, the separation trigger temperature can be increased. In this way, the rice can be cooked harder to produce pot-burnt according to the needs.

[0027] The device is simple and convenient to use. The user only needs to rotate the rotating adjusting block 12 to complete the adjustment of the trigger temperature. There is no technical threshold, so it is convenient to popularize and use. The adjustment range is set to two gears. When the adjusting block 12 is at the uppermost end, the initial elastic force of the second spring 13 is the smallest, and the separation trigger temperature of the first contact 6 and the second contact 9 is the highest. In this way, pot-burnt can be produced according to the needs. Conversely, when the adjusting block 12 is at the lowest position, the trigger temperature is the lowest. At this time, the trigger temperature for normal cooking of rice is 103 degrees.
