[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0035] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0037] The utility model embodiment provides a food processing machine, such as Figure 1 As shown, it includes: a body 100 having a receiving space and a cup body assembly 200 arranged in the receiving space of the body 100. Figure 2 As shown, the cup body assembly 200 includes a cup body main control chip 201 and a plurality of cup body functional components 202 connected to the cup body main control chip 201. During the operation of the food processor, each cup body functional component 202 realizes a corresponding cup body function under the control of the cup body main control chip 201.

[0039] Compared with the related art, in the food processing machine provided by the embodiment of the present invention, a cup body main control chip 201 is arranged in the cup body assembly 200, and the cup body main control chip 201 is connected to each cup body functional component 202 in the cup body assembly 200, and each cup body functional component 202 is controlled by the cup body main control chip 201 to realize the corresponding cup body function, and the connection between the cup body assembly 200 and the body main control chip 101 can be realized only by connecting the cup body main control chip 201 and the body main control chip 101 when the cup body assembly 200 is installed on the body 100, without connecting each cup body function component 202 to the body main control chip 101. The energy components 202 are respectively connected to the body main control chip 101 on the host. By setting a connection structure in which the cup body main control chip 201 is connected to the body main control chip 101 instead of the connection structure in which each cup body functional component 202 is respectively connected to the body main control chip 101 in the related technology, the connection structure between the cup body component 200 and the body main control chip 101 of the food processor is simplified. The simplification of the connection structure can reduce the number of connection ports between the cup body component 200 and the host 100, and reduce the probability of failure of the connection port when the cup body component 200 is disassembled and installed.

[0040] In some embodiments of the present invention, Figure 3 As shown, the cup body main control chip 201 is connected to the machine body main control chip 101 via a serial port circuit, and the serial port circuit is arranged on the cup body assembly 200.

By setting a three-terminal voltage regulator integrated circuit 300B, the high voltage input at the power input contact K is converted into a low voltage output at the power output contact VCC, so as to better supply power to each cup body functional component 202.

The cup body main control chip 201 realizes the forward, reverse, brake, and stop operations of the motor by controlling the level changes of the MOTO_R terminal and the MOTO_F terminal. For example, when MOTO_F is high and MOTO_R is low, the motor rotates forward; when MOTO_F is low and MOTO_R is high, the motor reverses; when MOTO_F is high and MOTO_R is high, the motor brakes; when MOTO_F is low and MOTO_R is low, the motor stops.

[0053] Specifically, Figure 7 After the serial port circuit shown is connected to the temperature acquisition circuit board 2023, it can actually be equivalent to Figure 8 The equivalent circuit shown is Figure 8 As shown, the equivalent circuit includes a temperature sensor 800, a contact 801 connected to the NTC terminal of the cup body main control chip 201, a contact 802 connected to the power output contact VCC, and a resistor 803 connected to the contact 802.

The cup body main control chip 201 inputs the voltage signal into the internal ADC peripheral through the contact 801, performs AD conversion, and obtains a numerical code that can uniquely represent the voltage value. The cup body main control chip 201 converts the code into a corresponding temperature value through a binary table lookup algorithm, thereby realizing the collection of the food temperature in the cup body component.

[0059] Specifically, Fig.13 As shown, the nozzle detection board 2025 includes two Hall elements 2025A and 2025B, and a magnet 2025C. The two Hall elements 2025A and 2025B are connected to the nozzle detection board connector 300H including terminals H1, H2, H3, and H4. The two Hall elements 2025A and 2025B respectively identify different nozzle positions 2025E and 2025D. When the magnet 2025C moves to the nozzle position identified by the Hall element 2025A, the Hall element 2025A senses the magnet. When the magnet 2025C moves to the position of the pulp nozzle marked by the Hall element 2025B, the Hall element 2025B senses the magnetic field signal and converts the signal into an electrical signal and sends it to the cup body main control chip 201 via the HL_K_1 terminal and HL_K_2 terminal of the cup body main control chip 201, so that the cup body main control chip 201 can obtain the specific position of the pulp nozzle.

The two Hall elements 2026A and 2026B respectively identify different valve core positions 2026D and 2026E. When the magnet 2026C moves to the valve core position 2026D identified by the Hall element 2026A, the Hall element 2026A The magnetic field signal is sensed and converted into an electrical signal and sent to the cup body main control chip 201 via the IL_K_3 terminal and IL_K_4 terminal of the cup body main control chip 201. Similarly, when the magnet 2026C moves to the valve core position 2026E marked by the Hall element 2026B, the Hall element 2026B senses the magnetic field signal and converts the signal into an electrical signal and sends it to the cup body main control chip 201 via the IL_K_3 terminal and IL_K_4 terminal of the cup body main control chip 201, so that the cup body main control chip 201 can obtain the specific position of the valve core.
