Please refer to fig. 10, which schematically illustrates an exploded view of the temporomandibular joint training apparatus according to an embodiment of the present invention. As shown in fig. 10, the inflation and exhaust device includes an air pump 1, the air pump 1 has two working modes of air pumping and air inflation, the air pump 1 is provided with an air inlet 11, an air outlet 12 and an air vent 13, the air outlet 12 of the air pump 1 is connected with the first insertion pipe 220A through a first air transmission pipeline 3, and the air inlet 11 of the air pump 1 is connected with the second insertion pipe 220B through a second air transmission pipeline 4. Because the utility model adopts the same air pump for air inflation and air exhaust, the utility model not only can reduce the number of parts and reduce the cost, but also can simplify the integral structure of the main machine and further reduce the weight of the temporomandibular joint training instrument. It should be noted that, as will be appreciated by those skilled in the art, in other embodiments, the inflation and deflation device may comprise two air pumps, one for inflation and one for deflation.

Preferably, in order to reduce the cost, the housing 210 of the main unit 200 is not completely closed, so that the inside of the housing 210 is communicated with the outside atmosphere, and thus, when the air pump 1 is in the inflation mode, the outside air can enter the air pump 1 through the vent hole 13, and the air pump 1 inflates the sucked air inside the airbag body 110 through the first air transmission pipeline 3 and the first insertion pipe 220A. When the air pump 1 is in the air pumping mode, air inside the airbag body 110 can be sucked into the air pump 1 through the second inserting pipe 220B and the second air transmission pipeline 4, and is finally discharged through the vent 13 on the air pump 1.

Specifically, when the air pump 1 is in the inflation mode, the check valve 31 is in the open state, so that the air delivered to the check valve 31 by the first air delivery pipeline 3 can only be ensured to enter, and therefore, the air inflated into the airbag body 110 can be prevented from flowing back into the air pump 1 through the check valve 31, and the normal operation of the temporomandibular joint training apparatus can be prevented from being affected. When pressure reduction or pressure maintaining is needed, namely the air pump 1 is in an air suction mode or a shutdown state, the one-way valve 31 is in a closed state, so that the phenomenon that the redundant air in the first air transmission pipeline 3 enters the air bag again to influence the normal operation of the temporomandibular joint training instrument can be avoided.

Therefore, when gas needs to be filled into the airbag body 110, under the control of the control panel 2, the air pump 1 is in an inflation mode, and the gas sucked into the air pump 1 through the vent 13 can be conveyed to the first air transmission pipeline 3 through the air outlet 12 of the air pump 1, conveyed to the first insertion pipe 220A through the first air transmission pipeline 3, and finally filled into the airbag body 110 through the first insertion pipe 220A, so that the airbag body 110 is expanded along the first direction D1. When pressure maintaining is needed, the air pump 1 is in a shutdown state under the control of the control board 2. When the air in the airbag body 110 needs to be exhausted, the air pump 1 is in an air exhaust mode under the control of the control board 2, and the air in the airbag body 110 can be conveyed to the second air transmission pipeline 4 through the second inserting pipe 220B, conveyed to the air pump 1 through the second air transmission pipeline 4, and finally exhausted through the vent 13 on the air pump 1.

Because the second inserting pipe 220B is always in a communicating state with the vent pipe 41, in order to prevent the gas filled into the airbag body 110 from flowing back into the air pump 1 through the vent pipe 41 in the inflating process, when the air pump 1 is in an inflating mode, the electromagnetic valve 42 is in a normally closed state under the control of the control panel 2. When pressure reduction is needed, under the control of the control panel 2, the air pump 1 is switched to an air suction mode, the electromagnetic valve 42 is in an open state, and air inside the airbag body 110 can reach the electromagnetic valve 42 through the vent pipe 41, and then is conveyed to the exhaust pipe 43 through the electromagnetic valve 42, and finally is discharged through the vent hole 13 on the air pump 1.

Therefore, the pressure sensor 5 can monitor the pressure inside the airbag body 110 in real time and send the monitored pressure value to the control board 2, so as to further improve the safety of the temporomandibular joint training instrument provided by the utility model in the using process. Specifically, when the pressure sensor 5 monitors that the pressure inside the airbag body 110 reaches a target pressure, the air pump 1 stops continuously inflating air into the airbag body 110 under the control of the control board 2; when the pressure sensor 5 detects that the pressure inside the airbag body 110 is too high and needs to be reduced, the air pump 1 is switched to an air-bleeding mode under the control of the control board 2 to reduce the pressure inside the airbag body 110 by discharging the gas inside the airbag body 110.
