In the implementation process, the external air source can adopt a simple inflatable ball which is connected with the air duct through the air duct 3, and only needs to continuously extrude the inflatable ball during inflation; the external air source can also adopt the existing inflator, and the inflator can be started to realize inflation after the air delivery pipe 3 of the inflator is connected with the air guide pipe. The air bag is provided with the measuring device capable of measuring the expansion height of the air bag, and a user can know the degree of mouth opening training at any time through the height value measured by the measuring device, so that the aim of accurate training is fulfilled.

The lower side of the air bag is connected with a flexible inverted U-shaped supporting plate 4, the lower teeth can be clamped into a U-shaped groove of the inverted U-shaped supporting plate, and the air bag can be quickly and accurately placed between the upper teeth and the lower teeth when the air bag is used conveniently; the inverted U-shaped supporting plate can prevent the air bag from sliding off the teeth after being placed, and the training is prevented from being influenced. Preferably, the air sac is divided into two sections, the two sections of air sacs are communicated through an air pipe 5, and the air guide pipe can be arranged on the air pipe or any section of air sac. In the implementation process, the two sections of air bags are respectively placed on the lower teeth on the two sides of the inner side of the oral cavity, and because the air bags are spread by the teeth close to the inner side, the teeth close to the outer side can be naturally spread, so that the air bags do not need to be designed close to the outer side, and only simple air pipe communication is needed. On one hand, the design can synchronously inflate the two sections of air bags through the air duct and the air pipe; on the other hand, the cost can be saved, the volume of the whole mouth gag is reduced, and the speed of the air bag for inflating and expanding is improved.

The invention also comprises a controller 6, and the height value measured by the measuring device is displayed on a panel 61 of a display part of the controller, so that a user can conveniently check the expansion height of the air bag at any time to monitor the mouth opening degree. Specifically, the controller comprises an MCU62, an input module 63 and an output module 64, the measuring device comprises a micro distance measuring sensor 65 which transmits a measuring signal to the input module through a wire 66, the input module transmits a signal to the MCU, and the MCU processes the signal and displays the measured height value on the panel through the output module. Therefore, the simple controller 6 is formed by adopting the distance measuring sensor, the MCU, the input module, the output module and the like, and the measurement and the display of the expansion height of the air bag are realized, so that the degree of the mouth opening training is monitored in real time, and the aim of accurate training is fulfilled.

Preferably, the miniature distance measuring sensor is arranged on a groove bottom plate of the inverted U-shaped supporting plate, the conducting wire is embedded in the groove bottom plate, and the conducting wire axially penetrates out of the air guide pipe from the pipe wall of the air guide pipe to be connected with the input module, so that the conducting wire is hidden, exposed and prevented from contacting with the oral cavity. And the miniature distance measuring sensor adopts a button type laser distance measuring sensor and is embedded in the groove bottom plate, only the transmitting port of the laser distance measuring sensor is ensured to be positioned in the bottom wall of the air bag, when the air bag is inflated and expanded, laser emitted by the transmitting port is transmitted to the top wall of the air bag from the bottom wall in the air bag, so that the expansion height of the air bag is measured, and a measuring signal is transmitted to the controller.
