Example one

The present application provides a food processor, which may comprise: the cup comprises a machine head and a cup body, wherein the machine head and the cup body are connected through a coupler, a first control unit U1 (which can be a first control chip) is arranged on the cup body, and a second control unit U2 (which can be a second control chip) is arranged on the machine head; a first TX pin 1-1 and a first RX pin 1-2 of the first control unit U1 are in short circuit, and a first lead is led out; a second TX pin 2-1 and a second RX pin 2-2 of the second control unit U2 are in short circuit, a second lead is led out, and the first lead is connected with the second lead;

the first control unit U1 or the second control unit U2 turns off its own data receiving function when data transmission is performed, turns on the data receiving function after data transmission is completed, and sets its own TX pin to be an input pin or an open-drain output high level.

In an exemplary embodiment of the present application, the data receiving function of the first control unit U1 is turned off when the first control unit U1 performs data transmission, the data receiving function is turned on after the data transmission is completed, and the first TX pin 1-1 is set to an input pin or an open-drain output high level; and the number of the first and second groups,

and when the second control unit U2 transmits data, the data receiving function of the second control unit U2 is turned off, and after the data transmission is finished, the data receiving function is turned on, and the second TX pin 2-1 is set to be an input pin or an open-drain output high level.

In an exemplary embodiment of the present application, as shown in fig. 2, the TX/RX pin of U1 and the TX/RX pin of U2 may be shorted, and the two shorted together by a wire harness. The embodiment scheme reduces the needle number and the wire harness number of the coupler, is beneficial to the design of structural modeling, and reduces the safety risk caused by winding and pressing the wire harness; the probability that the user takes the cup body when lifting the machine head is obviously reduced, and the user experience is improved.

In the exemplary embodiment of the present application, the TX and RX pins of the MCU (i.e., the first control unit U1 and the second control unit U2) are connected by a wire harness after being short-circuited, and the software is configured to close its own reception when the MCU transmits data, thereby completing half-duplex communication.

In an exemplary embodiment of the present application, the communication flow of the first control unit U1 and the second control unit U2 may be as shown in fig. 3. The first control unit U1 may be a master control unit (or simply a master), and the second control unit U2 may be a slave control unit (or simply a slave).

In an exemplary embodiment of the present application, the master may actively send data to the slave, and the slave may process and return data to the slave immediately after receiving a frame of data (a question and a answer). The master/slave shuts down its own reception during transmission, and specifically, may be implemented by setting a transmission flag bit or shutting down a reception interrupt. And the host/slave starts self receiving immediately after the transmission is finished, and simultaneously sets the corresponding TX pin as input or open-drain output high level.

In an exemplary embodiment of the present application, the handpiece may further be provided with a motor and a sensor respectively connected to the second control unit U2, the first control unit U1 sends a control command to the motor through the second control unit U2, and the second control unit U2 collects information of the sensor and the motor and feeds back the information to the first control unit U1.

In exemplary embodiments of the present application, the sensor may include, but is not limited to: temperature sensor, anti-overflow electrode and water level electrode.

In the exemplary embodiment of the present application, a thermistor type temperature sensor is generally used as a temperature sensor for detecting the temperature of the slurry, and is generally provided in the head, and the first control unit U1 is provided in the cup. The machine head is connected with the cup body through a coupler. Signals of temperature, overflow prevention and the like can be transmitted to the first control unit U1 of the cup body through the coupler, a motor (which can comprise a rotary valve motor) is arranged in the machine head assembly, control commands of the motor can be sent to the second control unit U2 by the first control unit U1 through the coupler, and the motor is controlled by the second control unit U2.

In the existing design, a four-pin coupler is generally required to complete the transmission of sensor signals, control signals and power, and comprises a grounding wire, a power wire and two signal communication wires, as shown in fig. 1. And the existing products have the following problems: when a user lifts the machine head, the cup body is easy to take up, and in severe cases, the cup body can be toppled over, and the skin can be scalded by the serous fluid; the coupler has too many needles, which causes large volume of the coupler, is not beneficial to structure and modeling design and influences the aesthetic property of the product; the coupler needle number is many, and the inside pencil of machine is more, has the condition emergence such as pencil winding, line ball, can produce safety risks such as short circuit, electric leakage when serious.

In the exemplary embodiment of the present application, the scheme of the present embodiment connects the TX/RX pins to a communication line at the same time, and performs bidirectional time-sharing transmission of data. The number of needles of the coupler is reduced, the design of structural modeling is facilitated, and the attractiveness of the product is enhanced. The probability that the user takes the cup body when lifting the machine head is obviously reduced, and the user experience is improved.

Example two

The embodiment is based on the first embodiment, and an embodiment of connecting resistors in series from the TX pin to the communication line is provided.

In the exemplary embodiment of the application, a first resistor R1 is connected in series between the first TX pin 1-1 and the first RX1-2 pin which are short-circuited with each other; and a second resistor R2 is connected in series between the second TX pin 2-1 and the second RX pin 2-2 which are mutually shorted.

In an exemplary embodiment of the present application, a resistor of about 1K may be connected in series between RX and TX of the two control units, as shown in fig. 4.

In the first exemplary embodiment of the present application, after the control unit (such as the first control unit U1 or the second control unit U2) finishes transmitting data, the TXD pin (i.e., the TX pin) must be set to be input or output-to-drain by software, and for some control units that do not support the software setting of the TXD pin (i.e., the TD pin) mode, when the control unit does not transmit data, the TXD (transmit data) pin outputs high level, and the TXD is directly connected to the RXD (receive data) pin, which may cause the RXD pin to continuously output high level, thus causing communication failure. In the scheme of the embodiment, the resistor is connected in series between the TXD and the RXD, so that the TXD cannot pull up the voltage on the communication line, and the communication can be correctly carried out in the control unit which does not support the software setting of the TXD pin output mode.

EXAMPLE III

This embodiment is based on the first embodiment, and provides an embodiment in which diodes are connected in series to the TX and RX pins of the control unit (e.g., the first control unit U1 or the second control unit U2).

In the exemplary embodiment of the present application, a first diode D1 is connected in series between the first TX pin 1-1 and the first RX pin 1-2, which are shorted to each other; a second diode D2 is connected in series between the second TX pin 2-1 and the second RX pin 2-2, which are shorted with each other.

In an exemplary embodiment of the present application, a cathode of the first diode D1 is connected to the first TX pin 1-1, and an anode of the first diode D1 is connected to the first RX pin 1-2; and the number of the first and second groups,

the cathode of the second diode D2 is connected to the second TX pin 2-1, and the anode of the second diode D2 is connected to the second RX pin 2-2.

In the exemplary embodiment of the present application, a third resistor R3 is connected in series between the anode of the second diode D2 and the power source VCC.

In an exemplary embodiment of the present application, as shown in fig. 5, diodes may be connected in series to the TX and RX pins of the control unit, and the cathodes of the diodes are connected to the TX pin.

In the exemplary embodiment of the present application, when the TXD of U1 outputs 1, the voltage of the communication line is pulled high by R3, so the RXD of U2 can receive 1. When the RXD of U1 outputs 0, the voltage of the communication line is pulled low by the RXD of U1 through D1, so the RXD of U2 can receive 0.

In the exemplary embodiment of the present application, when the master U1 transmits, the slave U2 is in the receiving state, and the TXD pin of the slave U2 in the receiving state outputs a high level, so that:

when the host U1 sends a signal 0, the TXD of the host U1 outputs a low level, the TXD of the slave U2 outputs a high level, the voltage on the communication line is 1/2VDD, i.e., the voltage on the RXD pin of the slave U2 is 1/2VDD, and for most control units, the pin voltage is lower than 0.8V and can be reliably identified as a low level, the pin voltage is generally in a non-transition region between 0.8V and 3.5V, and the pin voltage is higher than 3.5V, so the second embodiment may not be able to reliably communicate.

In the exemplary embodiment of the present application, the diode is connected in series between the TXD and the RXD, when the TXD outputs 0, the diode pulls down the voltage on the communication line, and when the TXD outputs high, the voltage on the communication line is pulled up by R3, so that the TXD sends 0 and 1, and the reliability of communication is improved.

Example four

The embodiment is based on the first embodiment, and as shown in fig. 6, an embodiment that applies single-wire bidirectional communication in a scheme with isolation requirement is given.

In an exemplary embodiment of the present application, an isolation circuit is disposed between the first control unit and the second control unit, and the isolation circuit includes a first isolation circuit U3 and a second isolation circuit U4 to implement single-wire bidirectional communication.

In an exemplary embodiment of the present application, the isolation circuit may be an opto-coupler isolation circuit.

In the exemplary embodiment of the present application, the input terminals of the first isolation circuit U3 are all connected to the first lead, the first output terminal of the first isolation circuit U3 is connected to the cathode of the first diode D1, and the anode of the first diode D1 is connected to the second lead; a second output terminal of the first isolation circuit U3 is grounded;

a first input end of the second isolation circuit U4 is connected with the second lead, a second input end of the second isolation circuit U4 is connected with a power supply VCC, and an output end of the second isolation circuit U4 is connected with the first lead; the first lead is also connected with a power supply VCC through a fourth resistor R4;

an anode of the second diode D2 is connected to the second lead, and a cathode of the second diode D2 is connected to the second TX pin; the second lead is also connected to a power supply VCC through a third resistor R3.

In an exemplary embodiment of the present application, as shown in fig. 6, U1 is a master, U2 is a slave, and U1 and U2 are respectively in power supply systems isolated from each other:

when the U1 sends data to the U2, the TXD of the U1 is low, the optocoupler U3 is turned on, and the voltage on the communication line is pulled low through the D1, so the RXD pin of the U2 can receive 0. The TXD of the U1 is high level, the optocoupler U3 is not conducted, the voltage on the communication line is pulled high by R3, and therefore the RXD pin of the U2 can receive 1;

when the U2 sends data to the U1, TXD of the U2 is low, and the voltage on the communication line is pulled low through the D2, so that the optocoupler U4 is turned on, and RXD of the U1 can receive 0. The TXD of U2 is high, the communication line is pulled high by R2, the opto-coupler U4 is non-conductive, the RXD of U1 is pulled high by R1 to VCC1, and thus 1 can be received.

In the exemplary embodiment of the present application, the master-slave software communication processing scheme is the same as that of the first embodiment.

In the exemplary embodiment of the application, an optical coupling isolation circuit is added on the basis of the third embodiment, and the requirement for single-wire communication in an isolation system is met.

EXAMPLE five

The embodiment is based on the third or fourth embodiment, and an embodiment that a schottky diode is connected in series on the TX pin to the communication line is provided.

In an exemplary embodiment of the present application, the first diode and the second diode are each a schottky diode.

In an exemplary embodiment of the present application, the series connected diodes are defined as schottky diodes.

In the exemplary embodiment of the present application, it is known that the common diode drop is around 0.7V; therefore, when the TX pin transmits data, the voltage of the communication line is pulled down through the diode, the low level is 0.7V, and the communication is in failure when the TTL level (transistor-transistor logic level) is connected to the upper limit of the low level (0.8V). The scheme of the embodiment uses the Schottky diode with the voltage drop of about 0.2V, so that the low level on the communication line can be closer to 0V, the control unit can reliably detect the low level of the communication line, and the communication reliability is further improved.

The communication method for the food processing machine provided by the embodiment of the application at least comprises the following beneficial effects:

1. the probability that the user takes the cup body when lifting the machine head is obviously reduced, and the user experience is improved;

2. the reliability and the real-time performance of the communication signal of the coupler of the food processor are improved, and the safety and the reliability of the pulping process are ensured;

3. the number of needles and the number of wire harnesses of the coupler are reduced, the design of structural modeling is facilitated, and safety risks caused by winding and pressing of the wire harnesses are reduced;

4. and the bidirectional data communication is convenient for the expansion of functional modules of the food processor.
