[0002] A food processor is a rotating and stirring cooking appliance, which generally has several functions such as cutting, beating meat, grinding beans, squeezing juice, making rice paste, and shaved ice. As consumers become more and more accepting of food processors, food processors with smaller size and smaller cooking capacity are gradually launched on the market, such as small food processors and garlic mashers (used for cutting and crushing small ingredients such as garlic, ginger, and small pieces of meat). Such small food processors are generally only equipped with a switch on the head. Consumers use the switch to start the cooking knife group of the food processor. After the head is separated from the container, the cooking knife group on the head can still be started and rotated, which poses a safety hazard and has certain limitations. Therefore, further improvement is needed. Utility Model Content

After the safety switch 5 is triggered, the driving device 6 can be started and operated, and the driving device 6 drives the cooking element 2 to operate to cook the food materials in the cooking cup 1.

[0024] The machine head 3 is provided with a transverse movement trigger rod 7 which moves along a transverse trajectory. The first end of the transverse movement trigger rod 7 is arranged opposite to the trigger end of the safety switch 5. The cooking cup 1 is provided with a driving member 8 which is matched with the second end of the transverse movement trigger rod 7. When the cooking cup 1 is docked with the machine head 3, the driving member 8 contacts the second end of the transverse movement trigger rod 7 and drives the transverse movement trigger rod 7 to operate, so that the transverse movement trigger rod 7 moves laterally in the machine head 3 and cooperates with the trigger end of the safety switch 5. Only then can the driving device 6 start to run and drive the cooking element 2 to run. After the machine head 3 is separated from the cooking cup 1, the safety switch 5 is not triggered, and the driving device 6 and the cooking element 2 are restricted from starting and running, thereby ensuring the safety of the food cooking machine.

[0025] In some embodiments of the present invention, Figure 1 , 2 As shown in 4, it includes a circuit board 9 electrically connected to the control board 4, and the safety switch 5 is arranged on the circuit board 9. The circuit board 9 and the control board 4 are separately arranged. The arrangement of the circuit board 9 makes it unnecessary for the safety switch 5 to be arranged on the control board 4, which facilitates the layout of the safety switch 5.

[0026] In some embodiments of the present invention, Figure 1 , 2 As shown in FIG. 4 , the circuit board 9 is arranged vertically, so that the trigger end of the safety switch 5 is arranged toward the side of the food processor.

The guide frame 11 and the guide groove 12 constitute a simple installation and guiding structure of the transverse movement trigger rod 7.

[0029] In some embodiments of the present invention, Figure 2 and 3 As shown, a transmission structure is provided between the transverse trigger rod 7 and the driving member 8, so that when the cooking cup 1 is docked with the machine head 3, the vertical relative movement between the transverse trigger rod 7 and the driving member 8 is converted into a lateral movement of the transverse trigger rod 7 in the machine head 3, so that the cooperation between the transverse trigger rod 7 and the driving member 8 can realize the triggering of the safety switch 5.

[0030] In some embodiments of the present invention, Figure 2 and 3 As shown, the transmission structure includes a guiding bevel 13, which is arranged on the upper part of the driving member 8. The distance between the guiding bevel 13 and the axis of the cooking cup 1 gradually decreases from top to bottom, so that when the cooking cup 1 and the machine head 3 are docked and installed in the vertical direction, the transverse movement trigger rod 7 can be driven by the guiding bevel 13 to move laterally toward the trigger end of the safety switch 5. In other embodiments, the guiding bevel 13 can also be arranged on the upper part of the driving member 8 and the second end of the transverse movement trigger rod 7 at the same time, or the guiding bevel 13 is only arranged on the second end of the transverse movement trigger rod 7.
