The display circuit comprises an LED digital display screen and an LED state display lamp assembly and is used for displaying working parameters such as power, temperature, capacity, time and the like and working states. The specific circuits of the key circuit and the display circuit are prior art and are not described in detail here.

And the NFC data transmission circuit comprises an NFC chip and an NFC antenna and is used for communicating with the mobile terminal with an NFC function so as to receive a working instruction sent to the execution element through the mobile terminal or exchange data. The NFC chip is internally stored with an identification corresponding to the food processor and used for being identified and paired by the mobile terminal with the NFC function.

The mobile terminal can be a smart phone, a tablet and a smart watch, and is provided with a display screen with a touch function, after the mobile terminal and the food processor are successfully matched, the corresponding application can be directly called, a preset control interface is started and entered, and a user can perform temporary interactive operation with the food processor through the display screen of the mobile terminal. The mobile terminal matched with the food processor is provided with a network communication module, and the food processor is communicated with the network through the mobile terminal.

The NFC antenna communicates with a mobile terminal that has completed pairing and is close to the NFC antenna by generating or listening to a radio frequency field, and the data transmitted by the communication includes a work instruction issued through (an operation interface of) the mobile terminal and related work status information (which is sent to the mobile terminal by the food processor) (so as to be displayed on the operation interface of the mobile terminal), or acquires related data stored on the mobile terminal (e.g., for updating recipes, adjusting cooking processes, updating firmware, etc.).

And the main control circuit is coupled with the UI interaction circuit and the NFC data transmission circuit, controls the execution element to work according to a corresponding preset working mode according to set working parameters or issued working instructions, and sends related working state information to the display circuit, or (after being paired with the mobile terminal) controls the NFC data transmission circuit to send the related working state information to the mobile terminal.

In this embodiment, the main control circuit is a single chip microcomputer, a signal terminal pin of a main control MCU (integrated circuit) of the single chip microcomputer is connected to the UI interaction circuit and the NFC chip, and a control terminal pin is connected to an MOS transistor driving circuit, and drives the motor through the MOS transistor. Correspondingly, the motor adopts a direct current brush motor. In addition, an alternating current motor (instead of a direct current brush motor) can be adopted according to the situation, and a corresponding motor driving circuit is configured, wherein the specifically configured driving circuit is well known by the technical personnel in the field and is not detailed here.

Example 2:

as shown in fig. 3, this embodiment shows another food processor based on NFC interaction, and compared to embodiment 1, this embodiment mainly shows another implementation of the master circuit and the NFC data transmission circuit.

In order to simplify the circuit, improve the communication efficiency and reduce the cost, in this embodiment, the main control circuit (chip) is integrated with the NFC chip, that is, the NFC chip has the resources of the main control chip, which can realize the function of the main control circuit, or the single chip has the port resources of the main control chip, also has the RF interface for NFC communication, and is connected to the NFC antenna through the RF interface, and the other port resources of the main control chip are used for controlling the food processor.

The master control circuit (chip) and the NFC chip are integrated on the same chip, so that communication between the two chips is reduced, and system reliability is improved. Due to the fact that transfer processing is saved in the data transmission process, the processing efficiency of the chip is higher, and user experience is better.

Example 3:

the present embodiment shows yet another NFC interaction based food processor. Compared with embodiment 2, in this embodiment, in order to further improve the data transmission efficiency and further optimize data exchange, a static random access memory, namely an SRAM, is integrated inside an NFC chip (or a master control circuit) to buffer received or uploaded complete data (to implement through transmission), and the buffer is released after the receiving is completed at the receiving end.

Meanwhile, partial data in the data transmission process is backed up conveniently. The NFC chip (or master control circuit) is provided with an EEPROM (electrically erasable and programmable read only memory) for backing up communication data for performing related operations for subsequent (re-) use.

More specifically, two data storage areas are arranged on the electrically erasable programmable read-only memory, and the uploading and the downloading of the data are stored in the data storage area which is planned in advance by the EEPROM.

As shown in fig. 4, in order to ensure that the receiving end can timely and completely receive data, an FD pin is disposed on the NFC chip, when an external NFC device is close to an antenna sensing area, the FD outputs a low level, the pin needs to be pulled up to VCC through a resistor, and the pull-up resistor is greater than 2K Ω.

When the main control chip detects that the FD signal is at a low level, it starts to receive or upload data (i.e., send local data to an external NFC device — a mobile terminal). The specific situation is as follows:

1. updating data to be uploaded at the host terminal to an NFC chip cache area in real time, and uploading the data when the NFC detects the mobile terminal;

2. when the data of the mobile terminal is downloaded, the NFC chip receives the data and temporarily stores the data in an SRAM cache region of the NFC chip, the main control chip detects that the FD signal is changed from high level to low level, a signal is sent to inform the NFC chip to be ready to receive the data, and the data are transmitted to the main control chip according to a protocol;

3. the main control chip processes the data, or executes related operations or stores the data into the EEPROM for backup so as to be used later.

The remaining technical features are the same as those of embodiment 1 or 2 and are not described in detail here.

According to the technical scheme, the communication efficiency is improved, the real-time performance is strong, the data downloaded by the external NFC equipment can be transmitted to the main control chip in time, and the main control chip responds and processes the data in time after receiving the data; the FD pin can save the running resources of the chip, does not need to communicate and read data all the time, and only receives the data when needed.

Example 4:

as shown in fig. 5, this embodiment shows a fourth embodiment of the food processor, in which the food processor is provided with a control panel and a sensing panel for placing the mobile terminal. The NFC data transmission circuit is arranged in the induction panel, and an NFC induction mark is arranged in a corresponding area of the induction panel (or a bracket for fixing the mobile terminal is arranged, for example, a frame capable of framing the mobile terminal is arranged in the induction area). The UI interaction circuit is arranged on the control panel. The control panel and the induction panel are integrally arranged, and the NFC induction identification is located above the UI interaction area.

Through the integrated setting of panel and the response panel integration will be controlled, can increase pleasing to the eye degree. Meanwhile, when the mobile terminal is used, the mobile terminal is placed at the position of the induction mark, the display screen of the mobile terminal can be used as an expansion screen of the control panel, the operation interface is placed at the same position in a concentrated mode, information is available in a list, and operation of a user is facilitated.

The rest of the structure and the features are the same as those of embodiment 1, and are not described in detail here.
