The user can read the pressure and time data through the display area of ​​the cover 10, and can also switch the display mode and set the time duration through the first touch control area and the second touch control area.

[0045] In order to realize the detection of steam pressure by the detection module 60, the detection module 60 is connected with the steam in the pressure cooker. Therefore, in this embodiment, the accommodation space in the shell 20 is divided into a first accommodation space 21 and a second accommodation space 23. The mainboard 40, the mounting bracket 30 and the power supply 50 are arranged in the first accommodation space 21, and the detection module 60 is arranged in the second accommodation space 23. The second accommodation space 23 is connected with the steam in the pressure cooker. Specifically, a connecting portion 22 is formed at the bottom of the shell 20, and the interior of the connecting portion 22 is hollow to form the second accommodation space 23. A through hole 24 is provided at the bottom of the connecting portion 22 to connect the steam. In order to facilitate the installation of the smart accessory, a threaded structure can also be designed on the outside of the connecting portion 22 to facilitate the detachable installation of the smart accessory on the pot body or pot cover of the pressure cooker.

[0046] The detection module 60 can be an integrated packaged smart chip, using a ceramic plate as a base material, and the pressure sensor and the internal signal processor are integrated by packaging. The temperature sensor can also be further integrated. The pressure sensor and the temperature sensor are used to detect the steam pressure and temperature data in the pressure cooker respectively. The internal signal processor converts and processes the pressure and temperature data and transmits them to the communication module 47 of the main board 40, and then displays them through the display module 41. Specifically, a second mounting groove 28 is provided at the bottom of the first accommodating space 21, and the second mounting groove 28 is connected to the second accommodating space 23. The integrated smart chip card of the detection module 60 is arranged in the second mounting groove 28. Threaded holes can be provided on both sides of the second mounting groove 28. A communication data board 70 is arranged above the second mounting groove 28. The communication data board 70 can be fixed in the threaded holes by bolts. The communication data board 70 is used for communication connection between the detection module 60 and the controller 40, and also plays a role of separating the first accommodating space 21 and the second accommodating space 23.

[0047] In the above technical solution, the pressure sensor and temperature sensor in the integrated intelligent chip serving as the detection module 60 are respectively used to detect the steam pressure and temperature in the pressure cooker, and transmit the steam pressure and temperature data to the main board 40 through the communication data board 70; the display module 41 is used to display the steam pressure data or display time data in the pressure cooker; the operator touches and controls the first touch control area, and the display module 41 switches to the pressure display mode for displaying the steam pressure value in the pressure cooker; the operator touches and controls the second touch control area, and the display module 41 switches to the time display mode. At this time, further operation of the second touch control area can set and display the cooking time; when the steam pressure / temperature value in the pressure cooker exceeds the set value or the countdown reaches the set value, the alarm module 44 of the main board 40 sends an alarm signal to remind the user.

[0048] See also Figure 9-12, which is a schematic diagram of the display mode of the smart accessory. The specific operation method is as follows: touch the first touch control area, the main board 40 displays the steam pressure value detected by the detection module 60 through the display module 41, and the user can read the above pressure value through the display area of ​​the cover 10; touch the second touch control area, and the main board 40 displays the time mark through the display module 41. In this embodiment, the time adjustment uses a cycle system: 0-60 cycles, that is, the cycle is 0 after 60. The specific adjustment method is as follows: 0-10, each time the second touch control area is touched, the duration increases by 1; 10-20, each time the second touch control area is touched, the duration increases by 2; 20-60, each time the second touch control area is touched, the duration increases by 5; after the duration is set, the display module 41 goes out once and the time is locked. Press and hold the second touch control area for more than 2s, the duration is reset to zero and the time is reset.

[0049] After the duration is set, the steam pressure reaches 1kpa and the timing module starts counting down. When the set time is reached, the display module 41 automatically lights up and displays the set countdown time (for example, if the set time is 20, the display module 41 displays 20), and the alarm module 44 sends an alarm signal to prompt the countdown to start. After that, touching the first touch control area displays the pressure data, and touching the second touch control area displays the remaining time.

[0050] Furthermore, the display module 41 can also realize charging display. When the charging port 11 is connected to an external power source, a battery symbol is displayed; when the external charging power source is unplugged, the battery symbol goes out. When the voltage of the power supply unit 50 is lower than the preset value, the battery symbol flashes quickly to remind the user to charge in time. When the user fails to charge in time and the voltage of the power supply unit 50 is lower than the preset voltage, the smart accessory automatically shuts down. After shutting down, if the voltage of the power supply unit 50 recovers to above the preset value, it will automatically start up again and can continue to be used.

[0051] When the steam pressure or temperature value in the pressure cooker reaches the preset warning value, the main board 40 sends an alarm signal through the alarm module 47 to remind the user that there may be danger. In this embodiment, when the steam pressure in the pressure cooker is higher than 130kpa, the alarm module 47 will send an alarm signal, which can be a sound signal or a pattern flashing signal. In this embodiment, the alarm module 47 is a buzzer. When the steam pressure is too high (or the temperature is too high, the countdown is too long), the buzzer sends a buzzer prompt signal to remind the user to handle it in time.

[0052] Applying the smart accessories of this embodiment to the pressure cooker can improve the safety and intelligence level of the pressure cooker, thereby greatly improving the user experience; at the same time, the smart accessories of this embodiment are small in size and low in cost, and are suitable for large-scale promotion and application.
