[0029] The emergency stop nasal aspirator of the present invention includes an electronic microprocessor, operation buttons, a charging management circuit, a first boost circuit, an air pump drive circuit, a voice circuit, a second boost circuit, a lighting circuit, and a display module.

[0030] The electronic microprocessor is mainly responsible for the operation and detection of the entire system. The operation buttons and four button signals are directly sent to the microprocessor for processing. SW1 is the power on / off and mode selection button, and SW5 is the nasal suction operation button in manual mode. This button is only functional when manual mode is selected through the SW1 button.

[0031] The charging management circuit, mainly composed of chip IC1 and other peripheral devices, primarily manages the charging of the internal lithium battery to prevent overcharging. Resistors R2 and R4 detect the external power supply, and this detection signal is directly sent to the microprocessor so that the microprocessor can identify whether an external power supply is connected. Resistors R6 and R9, and capacitor C10 detect the lithium battery voltage, and this detection signal is directly sent to the microprocessor. The microprocessor monitors the battery voltage in real time, and takes appropriate action if the voltage drops.

[0032] The first boost circuit is mainly composed of chip IC2, which provides voltage to drive the air pump. MOSFETs Q1 and Q2 form an electronic switch to prevent direct voltage transfer to the lithium battery when the USB port has voltage. When the device is powered off, MOSFETs Q5 and Q6 disconnect the lithium battery from the subsequent circuit, thereby reducing standby power consumption.

[0033] The air pump drive circuit is mainly composed of MOSFET Q3.

[0034] The voice circuit, mainly composed of IC5 and other external components, primarily drives the speaker to play music.

[0035] The second boost circuit primarily provides a stable power supply for the electronic microprocessor.

[0036] The display module, directly driven by the electronic microprocessor, primarily displays relevant system operating mode information. The display module uses a two-digit or multi-digit LED display with multiple indicator icons. Other display modules such as TFT, LCD, and VFD can be used as substitutes. The manual mode switch can be replaced by any other type or shape of switch.
