[0038] The mouth muscle training device also includes: a rechargeable battery 106; the rechargeable battery 106 is connected with the MCU main control chip 101 for power supply.
[0039] The output module includes several LED lamps 107; the MCU main control chip 101 is connected with the LED lamps 107. Specifically, it may include a first group of LED lamps 107 and a second group of LED lamps 107; the MCU main control chip 101 is connected with the first group of LED lamps 107 so as to The ratio of the target pressure value controls the display of the first group of LED lamps 107; the MCU main control chip 101 is connected with the second group of LED lamps 107 to control the second group of LED lamps 107 according to the ratio of the number of times the target pressure has been reached and the number of times the target is reached. display.
[0040] The output module also includes a sound playback unit; the sound playback unit includes a FLASH chip 108, an audio decoding chip 109, a power amplifier chip 110 and a loudspeaker 111; the MCU main control chip 101 is connected with the FLASH chip 108 to read Audio file to be played; the audio decoding chip 109 is connected with the MCU main control chip 101 to decode the audio file; the power amplifier chip 110 is connected with the audio decoding chip 109; the loudspeaker 111 is connected with the audio decoding chip 109; The power amplifier chips 110 are connected to each other.
[0041] The two groups of LED lamps 107 can be provided with 10 LED lamps for each group. When the child blows air, the MCU main control chip 101 obtains the value of the air pressure sensor 102, calculates a percentage according to the target pressure value set by the parents, and then lights up the first group of 10 LEDs according to the percentage. The lamp 107 is used to indicate the magnitude relationship between the actual pressure value and the target pressure value, one LED lamp 107 is lit every 10%, and so on.
[0042] When the target pressure value set by the parents is reached, the number of times of reaching the standard is automatically accumulated, and a percentage is also calculated according to the target number of times of reaching the standard set by the parents, and then according to the percentage, the 10 LED lights 107 of the second group are lit in turn, To indicate the completion progress of the training, one LED light 107 is lit every 10%, and so on.
[0043] When the number of times the target reaches the standard is reached, the training is completed, and the MCU main control chip 101 reads the music file in the FLASH, decodes and amplifies it, and finally plays it through the loudspeaker 111 .
[0044] see figure 2 Shown is a flow chart for setting the buttons 104, specifically, it may include three buttons 104, namely "+ button", "- button" and "confirmation button". The button 104 can be a physical button 104 set on the shell of the oral muscle training device, or it can be a soft button 104 , such as being presented through the button 104 on the touch-type liquid crystal display 105 .
[0045]The "confirmation key" is used to select setting items or save settings, and the set items include target pressure setting and target attainment times setting.
[0046] see image 3 As shown, when pressing the "confirmation key" to set the item, the cursor indicator is also included in front of the currently set item, press the "+ key", the cursor moves up, press the "- key", the cursor moves down, and the selection is carried out. The target pressure setting is still the setting of the target number of times to reach the standard.
[0047] When the cursor points to the target pressure setting, press the "+ key" to increase the target pressure value, and press the "- key" to decrease the target pressure value.
[0048] When the cursor points to the setting of the number of target attainment times, press the "+ key" to increase the number of target training times, and press the "-key" to decrease the number of target training times.
[0049] After setting the target pressure value and the number of times to reach the target, you can press the "confirmation key" to save the settings.
[0050] After the setting is completed, the liquid crystal display 105 displays the target pressure value and the number of times the target is reached.
[0051] Of course, the real-time pressure value transmitted by the air pressure sensor 102 detected by the MCU main control chip 101 can also be displayed on the liquid crystal display 105, and the number of times the standard has been reached is displayed according to calculation.
[0052] In the embodiment of the present invention, the MCU main control chip 101 selects STM32F103C8T6; the air pressure sensor 102 selects XGZP020SB1; the liquid crystal display 105 screen selects a 12864 OLED module; the audio decoding chip 109 selects VS1053; the power amplifier chip 110 selects HT6872; The speaker 111 is 2W/8Rφ40mm; the FLASH chip 108 is W25Q256.

[0054] The MCU main control chip converts the voltage output by the air pressure sensor into a pressure value through the internal A/D module; the air pressure sensor is connected to the blowing module;
[0055] The MCU main control chip judges whether the currently detected pressure value reaches the set target pressure value, and if so, lights up the first group of LED lights, and increases the number of times that the standard has been reached by 1;
[0056] The MCU main control chip judges whether the number of reaching the standard has reached the set target number of reaching the standard, and if so, lights up the second group of LED lights and plays music.
[0057] Concrete, described mouth muscle training method also includes:
[0058] The MCU main control chip controls the number of lights in the first group of LED lights according to the ratio of the detected pressure value to the set target pressure value;
[0059] The MCU main control chip controls the number of lighted lights in the second group of LED lights according to the ratio of the number of times that the standard has been reached to the number of times that the target is reached.
[0060] The above is only a specific embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any non-substantial changes made to the present invention by using this concept should be an act of violating the protection scope of the present invention.
