and when the detection signal is greater than the temperature threshold signal, the switch submodule disconnects a power supply loop of the heating wire.
6. The hot air blow-drying system for the pressure-regulating type medical instrument according to claim 5, characterized in that: the control circuit comprises an infrared sensor installed on the sealing shell, the infrared sensor is coupled with the control circuit, the infrared sensor is used for detecting the temperature of the medical appliance to be air-dried and transmitting a temperature signal to the control circuit, and the control circuit receives the temperature signal and sends a control signal to the switch circuit to control the power supply loop of the heating wire to be disconnected when the temperature signal is greater than a temperature threshold signal.
7. The hot air blow-drying system for the pressure-regulating type medical instrument according to claim 3, characterized in that: the pressure threshold is 0.1-0.8 MPA.
8. The hot air blow-drying system for the pressure-regulating type medical instrument according to claim 5, characterized in that: the temperature threshold is 25 ℃ to 80 ℃.
9. The hot air drying method for the pressure-regulating type medical instrument according to claim 1, characterized in that: the method comprises the following steps:
acquiring a current pressure signal of a pressure probe (9) to generate first pressure information;
if the first pressure information is detected to be larger than the first reference value, adjusting the pressure value of the pressure regulator (4) according to the current first pressure information so that the current first pressure information of the pressure regulator (4) is smaller than the first reference value;
acquiring the pressure value of the sealed shell (1) in real time to generate second pressure information;
and if the second pressure information is kept to be acquired to be larger than the second reference, controlling the air inlet control valve (3) to be closed according to the current second pressure information.
