[0053] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed by the present invention.

[0054] Please refer to Figure 1 The present invention provides a cooking machine, comprising a fixed seat 1, a first driving structure 2, an agitator 6, a second driving structure 3, a pressure detection structure 4 and a control unit 8. The first driving structure 2 is mounted on the fixed seat 1. The agitator 6 is mounted on the fixed seat 1 and is transmission-connected to the first driving structure 2. The first driving structure 2 can drive the agitator 6 to rotate in the horizontal direction relative to the fixed seat 1. The second driving structure 3 is mounted on the fixed seat 1 and is transmission-connected to the agitator 6. The second driving structure 3 can drive the agitator 6 to slide back and forth in the vertical direction relative to the fixed seat 1 for a preset distance. The pressure detection structure 4 is mounted between the second driving structure 3 and the agitator 6, and is used to detect the actual force Fn of the second driving structure 3. The upward force on the second driving structure 3 is positive, and the downward force on the second driving structure 3 is negative. The control unit 8 is mounted on the fixed seat 1 and is communication-connected to the first driving structure 2, the second driving structure 3, and the pressure detection structure 4.

[0055] The cooking machine provided by the present invention drives the stirrer 6 to rotate by setting a first driving structure 2, thereby stirring the ingredients during the cooking process and evenly heating and cooking the ingredients. The stirrer 6 is driven up and down by setting a second driving structure 3, thereby adjusting the height of the stirrer 6 relative to the cooking pot 9, thereby adjusting the force between the stirrer 6 and the cooking pot 9, and then adjusting the scraping force of the pot, reducing the probability of ingredients sticking to the pot, thereby improving the cooking effect.

[0056] Optionally, the stirrer 6 includes a stirring shaft 61 and a stirring shovel 62 disposed at the lower end of the stirring shaft 61, the stirring shaft 61 is vertically mounted on the fixing base 1 and is transmission-connected to the first driving structure 2 and the second driving structure 3, and the stirring shovel 62 is used to stir the ingredients. Figure 2 When the stirring shovel 62 is not in contact with the cooking pot 9, the stirrer 6 is subjected to its own downward gravity G. At this time, the actual force Fn of the pressure detection structure 4 is downward and equal to G, that is, Fn is a negative value. Please refer to Figure 3 When the stirring shovel 62 contacts and squeezes the cooking pot 9, the stirrer 6 is subjected to a relative upward force from the cooking pot 9. At this time, the actual force Fn of the pressure detection structure 4 is upward, that is, Fn is a positive value.

[0057] Optionally, it also includes a first gear 7, which is sleeved on the outside of the stirring shaft 61. The first driving structure 2 includes a driving motor 21 and a second gear 22 installed at the output end of the driving motor 21. The first gear 7 is meshed and connected with the second gear 22, thereby driving the stirring shaft 61 to rotate.

[0058] Optionally, the height of the first gear 7 is smaller than or greater than the height of the second gear 22 , so that when the second gear 22 follows the lifting and lowering of the stirring shaft 61 , it can still be ensured to be meshed and drivenly connected with the first gear 7 .

[0059] Optionally, a double ball head connector 5 is further included, which includes a connecting body 51, a first ball head 52 arranged at the upper end of the connecting body 51, and a second ball head 53 arranged at the lower end of the connecting body 51. A first spherical groove adapted to the first ball head 52 is opened at the lower end of the pressure detection structure 4, and the first ball head 52 extends into the first spherical groove and can rotate relative to the first spherical groove. A second spherical groove adapted to the second ball head 53 is opened at the upper end of the stirring shaft 61, and the second ball head 53 extends into the second spherical groove and can rotate relative to the second spherical groove. By arranging the first ball head 52 to cooperate with the first spherical groove and the second ball head 53 to cooperate with the second spherical groove, when the stirring shaft 61 rotates, the probability of the stirring shaft 61 driving the pressure detection structure 4 to rotate is reduced, so that the pressure detection structure 4 is relatively stable, and thus the possibility of the second driving structure 3 being driven can be indirectly reduced, thereby improving the installation stability of the second driving structure 3.

[0060] Optionally, the pressure detection structure 4 includes a pressure detector 41, a first connecting part 42 arranged at the upper end of the pressure detector 41, and a second connecting part 43 arranged at the lower end of the pressure detector 41. The first connecting part 42 is connected to the output end of the second driving structure 3, and a first spherical groove is opened at the lower end of the second connecting part 43. By setting the first connecting part 42 and the second connecting part 43, on the one hand, it is convenient to install the pressure detector 41, and on the other hand, it is convenient to connect the pressure detector 41 with the output end of the second driving structure 3 and the double ball head connector 5.

[0061] Optionally, the second driving structure 3 is a push rod motor, and a third ball head 31 is arranged on the output shaft of the push rod motor. A third spherical groove adapted to the third ball head 31 is opened at the upper end of the first connecting part 42. The third ball head 31 extends into the third spherical groove and can rotate relative to the third spherical groove. By setting the third ball head 31 and the third spherical groove, the possibility of the stirring shaft 61 driving the push rod motor to move through the pressure detection structure 4 is further reduced, thereby further improving the installation stability of the push rod motor.

[0062] Optionally, a accommodating cavity is opened in the fixed base 1, and the first drive structure 2, the second drive structure 3, the pressure detection structure 4, the control unit 8 and the upper part of the agitator 6 are all arranged in the accommodating cavity. On the one hand, a waterproof effect is achieved for the first drive structure 2, the second drive structure 3, the pressure detection structure 4, and the control unit 8, and on the other hand, an aesthetic effect is achieved. At the same time, it avoids the first drive structure 2 and the second drive structure 3 from causing harm to the user when they move, thereby ensuring the safety of the cooking machine.

[0063] Optionally, a guide groove 10 extending in the vertical direction is provided in the fixed seat 1, and the upper part of the agitator 6 and the pressure detection structure 4 are both arranged in the guide groove 10 and can slide along the guide groove 10. By setting the guide groove 10, the stability of the agitator shaft 61 moving in the vertical direction is ensured.
