Respiration aiding equipment

Respiration aiding equipment, comprising:

• a main control module,
• a heating loop, comprising a temperature detection module to detect first temperature data of the heating loop, and
• a heating loop protective circuit connected to the heating loop,
• wherein the heating loop protective circuit comprises an acquisition sub-circuit, a suppression sub-circuit, a protective sub-circuit, a discharge sub-circuit and a temperature detection sub-circuit to detect second temperature data of the heating loop protective circuit;
• the protective sub-circuit is connected to the temperature detection module of the heating loop and generates input voltage according to the first detected temperature data, the acquisition sub-circuit collects the input voltage of the protective sub-circuit and sends the input voltage to the suppression sub-circuit;
• the suppression sub-circuit clamps the input voltage and releases current through the discharge sub-circuit;
• and the protective sub-circuit performs short-circuit protection when the current is too high;
• wherein the discharge sub-circuit comprises a discharging diode, a discharging resistance and a discharging switch tube, an input end of the discharging diode is accessed into control voltage of the main control module, an output end of the discharging diode is connected to one end of the discharging resistance and a control end of the discharging switch tube, an input end of the discharging switch tube is connected to the suppression sub-circuit, and an output end of the discharging switch tube is connected to the other end of the discharging resistance, the temperature detection sub-circuit and grounded.
