[0002] Most of the existing food processors on the market have a reservation function, which can be scheduled according to user needs. The existing production method is: water and corresponding ingredients are placed in the cup of the food processor in advance. When the set reservation time is reached, the control system on the food processor controls the heating module to heat to make the corresponding food. Since this operation requires the ingredients to be soaked in water for a long time, this will result in a poor taste of the prepared food, especially in summer when the outside temperature is high. The ingredients soaked in water for a long time will cause the prepared food to have a strange smell, which will affect the taste and may even affect the health of the user.
[0003] At present, there are some automatic dropping mechanisms on the market, which use the impact force generated by the eddy current in the mixing cup to open the dropping mechanism, and in order to obtain sufficient impact force, the dropping slurry needs to extend to the bottom of the mixing cup, which makes the overall mechanism bloated. At the same time, since the opening and closing of the dropping mechanism is easily affected by the water flow, the dropping mechanism cannot effectively maintain the open state, which may easily lead to problems such as food not being able to fall normally or the falling of food being interrupted.

That is, when the second magnet 42 moves away from the discharge channel 22 relative to the first magnet 41, it can trigger the mutual repulsion between the first magnet 41 and the second magnet 42, thereby driving the push rod assembly 3 to leave the discharge channel 22 to open the discharge channel 22.Preferably, the air pressure change generated when the heating chamber 11 is heated drives the push rod assembly 3 to drive the second magnet 42 to move away from the discharge channel 22, thereby changing the distance between the first magnet 41 and the second magnet 42 so that the first magnet 41 and the second magnet 42 repel each other, thereby driving the push rod assembly 3 to leave the discharge channel 22 to open the discharge channel 22, and the repulsive force between the first magnet 41 and the second magnet 42 can effectively maintain the open state of the discharge channel 22, thereby ensuring that the food stored in the silo 2 can smoothly pass through the discharge channel 22 into the heating chamber 11.

[0035] See also Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments, the second magnet 42 is assembled at the end of the push rod assembly 3 or the middle of the push rod assembly 3. When the air pressure change generated by the heating chamber 11 during heating drives the push rod assembly 3 to drive the second magnet 42 to move, the magnetic field of the first magnet 41 and the magnetic field of the second magnet 42 interact with each other, so that the first magnet 41 and the second magnet 42 repel each other. Preferably, the push rod assembly 3 includes a push rod body 31, and the second magnet 42 is assembled at the lower end of the push rod body 31, and the lower end of the push rod body 31 is cooperatively connected to the discharge channel 22.

In this way, when the heating chamber 11 is heated, the internal air pressure of the heating chamber 11 can be increased to push the push rod body 31 to move away from the discharge channel 22. At the same time, the second magnet 42 is driven by the push rod body 31 to move synchronously away from the discharge channel 22, thereby achieving the purpose of changing the distance between the first magnet 41 and the second magnet 42, so that the first magnet 41 and the second magnet 42 repel each other, thereby driving the push rod assembly 3 to leave the discharge channel 22 to open the discharge channel 22, and the repulsive force between the first magnet 41 and the second magnet 42 can be used to effectively maintain the open state of the discharge channel 22, thereby ensuring that the food stored in the silo 2 can smoothly pass through the discharge channel 22 into the heating chamber 11.

After the device is completed, the top cover 5 is covered on the opening to close the storage silo 2 to prevent the food stored in the storage cavity 21 from being disturbed or contaminated by the outside world. Furthermore, the top cover 5 is provided with a movable channel 51, and the upper end of the push rod assembly 3 is movably arranged in the movable channel 51.

The upper end of the push rod body 31 is movably arranged in the active channel 51. When the internal air pressure of the heating chamber 11 changes, the internal air pressure of the heating chamber 11 pushes the push rod body 31 to move upward. At the same time, the active channel 51 can guide the push rod body 31 to move in the height direction to ensure that the internal air pressure of the heating chamber 11 can push the push rod body 31 to move upward, so as to change the distance between the first magnet 41 and the second magnet 42, thereby triggering the mutual repulsion between the first magnet 41 and the second magnet 42.
