The voltage regulating electronics may be a diode. The voltage regulating electronics are embodied in a neutral line.

In some embodiments, the voltage regulation electronics 1430 includes a buck diode to cause the voltage of the first loop to be lower than the voltage of the second loop, such that the power source outputs a different rotational speed when forming the second loop than when forming the first loop, such as the power source outputs a lower rotational speed when forming the first loop than when forming the second loop.

Based on the above structure, when the user operates the button 11 and moves the button 11 inward for a certain distance (for example, 2mm to 4mm), the driving member 141 is driven by the button 11 to move to the first position, so that the first concave portion 14101 moves to a position corresponding to the first touch portion 1431, the first touch portion 1431 is released to pop up, and the first position switch 143, the power source and the power source form a first circuit. Further, the operation button 11 is continuously moved inward by a certain distance (2mm to 3mm), the first touching portion 1431 is pressed by the first protrusion 14103, and the first position switch 143 is turned off. The button 11 is continuously operated to move inward for a certain distance (for example, 2mm to 4mm) to a second position (as shown in fig. 12 and 13), the second protrusion 14102 moves to a position corresponding to the second touch portion 1441, so that the second touch portion 1441 is pressed in, and the second position switch 144, the power source and the power source form a second circuit.

In other embodiments, the first position switch 143 and the second position switch 144 may also be implemented by the same micro-switch, such as the switch structure 14' shown in fig. 14-17. Referring to fig. 14 and 17, the same or similar structures of the switch structure 14' and the switch structure 14 are designated by the same reference numerals as in the switch structure 14. In contrast, in the embodiment shown in fig. 14 to 17, when the second trigger 1441 of the second position switch 144 is pressed in, the second position switch 143 is in the off state, and when the second trigger 1441 is released and ejected, the second position switch is closed. The actuator 141 of the switch structure 14' is in an initial position as shown in fig. 14 and 15. When the user operates the button 11 and moves the button 11 inward for a certain distance, the driving member 141 is driven by the button 11 to move to the first position, so that the first concave portion 14101 moves to a position corresponding to the first touch portion 1431, so that the first touch portion 1431 is released to eject, and the first position switch 143 forms a first loop with the power source and the power source. Further, the operation button 11 is moved inward, the first touching portion 1431 is pressed by the first protrusion 14103, and the first position switch 143 is turned off. When the operation button 11 continues to move inward, the second concave portion 14104 moves to a position corresponding to the second touching portion 1441, so that the second touching portion 1441 is released to pop up, and the second position switch forms a second loop with the power supply and the power supply.

It should be noted that, in the embodiment shown in fig. 14 to 17, the triggering of the first trigger 1431 may be understood as triggering the ejection of the first trigger 1431, and the triggering of the second trigger 1441 may be understood as triggering the ejection of the second trigger 1441.

It should be noted that, in other embodiments, the first position switch and the second position switch may specifically be other types of switch structures. The number of position switches may also be 3 or more. The specific setting mode and the setting position of the position switch and the driving piece can be set according to specific conditions, for example, the position switch and the driving piece can be arranged on the same side of the driving piece, and the application does not limit the setting mode and the setting position. In addition, the driving member can also be matched with the first position switch and the second position switch through other movement modes, such as rotation. The first position switch and the second position switch can be correspondingly arranged on two sides of the driving piece, and the driving piece rotates to the corresponding side, so that the action of the touch part of the position switch corresponding to the side can be triggered, and the position switch is closed. Accordingly, the external force applied to the driver operating portion can rotate the driver. Specifically, when the driving member operating portion receives an external force, the driving member can rotate in the axial direction of the key driving member main body portion.

The stirring main machine component also comprises a main machine shell 17, an upper cover 13 and a motor bracket 15. The upper cover 13 covers the main housing 17 to form a containing space, the motor 16 is disposed in the containing space through the motor bracket 15, and the switch structure 14 is disposed in the containing space and electrically connected to the motor 16. The button 11 is movably provided on the upper cover 13 by a spring 12. The inner end of the button 11 is provided with a connection post 111, and the connection post 111 can be contacted with a contact portion 14111 of the outer end of the driving member operating portion 1411. The button 11 can move inward under the action of external force, thereby driving the driver 141 to move. When no external force is applied to the button 11, the button 11 may rebound to the initial position of the spring 12 by the spring 12. Accordingly, the driving member 141 also returns to its corresponding initial position.

Further, in some embodiments, the mixing host assembly further includes a safety link 18 and a safety switch 19. The safety switch may be a microswitch. The safety switch 19 is arranged in the accommodating space. The safety link 18 is movably disposed at one side of the safety switch 19 (e.g., below the safety link) and is exposed from the main housing 17. After the stirring main machine assembly is installed on the cup cover 20, the safety connecting rod 18 can abut against the cup cover 20 and can move towards the safety switch 19 under the action of the cup cover 20 to trigger the safety switch 19 to be closed, so that the power supply of the stirring main machine assembly 10 is switched on, and then the stirring main machine assembly 10 can drive the stirring knife assembly 40 to perform stirring operation after the operation button 11. In some embodiments, an abutment post 2003 is provided at the bottom of the mounting space 2001 of the cap 20, and the safety link 18 specifically abuts against the abutment post 2003.
