一种控制电路及通气治疗设备
By designing a control circuit in the ventilation therapy device that includes a capacitor, a processor, a first control switch, and a threshold setting circuit, the problem of the processor failing to start normally after a power outage is solved. This enables the processor to switch normally between power outage and power supply states, ensuring that the device can start and operate normally after a power outage.

AI Technical Summary
The processor of the existing ventilation therapy equipment cannot start normally after a power outage, which causes the audible and visual alarm device to malfunction. Furthermore, when the power is restored, the processor's power-on sequence does not meet the requirements, preventing it from starting normally.
Design a control circuit including a capacitor, a processor, a first control switch, and a threshold setting circuit. The first control switch disconnects the power supply circuit when the capacitor output voltage is lower than the threshold voltage, putting the processor in a power-off state, eliminating the 'refractory period', and ensuring that the processor can start normally the next time it is connected to power.
It enables the processor to switch normally between power-off and power-on states, ensuring that the ventilation therapy equipment can start and work normally after a power outage, thus improving the operability of the equipment.
