Nebulization device having dual modules

A nebulization device having dual modules, comprising:

• a nebulization host machine;
• a three-way tube communicated with the nebulization host machine;
• a controller connected to the nebulization host machine;
• and
• a ventilator and a mask communicated with the three-way tube respectively;
• wherein:
• the nebulization host machine comprises a side cover, a nozzle arranged on one side of the side cover, a liquid medicine bottle arranged on the other side of the side cover and communicated with the nozzle, a nebulization sheet arranged on one side of the liquid medicine bottle and communicated with the nozzle, and a first plug-in interface arranged below the liquid medicine bottle;
• a bottom portion in the nozzle is provided with a partition plate that divides an interior of the nozzle into an upper nebulization chamber and a lower gas flow chamber;
• the partition plate is provided thereon with a gas flow detection structure extending into an interior of the three-way tube;
• the gas flow detection structure comprises an inverted trapezoidal plate that is arranged on the bottom portion of the nozzle and integrally connected to the nozzle, and extends into the interior of the three-way tube, a protrusion that is arranged in the interior of the three-way tube and abuts against an end portion of the inverted trapezoidal plate, a gas chamber that is arranged in an interior of the inverted trapezoidal plate and communicated with the ventilator, and contains a gas flow, a slot arranged in an inner wall of the inverted trapezoidal plate, a sensor arranged in the slot for detecting gas flowing through the gas chamber, and a first circuit board arranged in the first plug-in interface and connected to the sensor;
• the nebulization sheet is connected to the first circuit board;
• and
• the sensor detects a gas flow signal in the gas chamber, and then sends the signal to the controller, and the controller drives the nebulization host machine to generate a nebulized liquid medicine to be ejected from the nozzle for administration.
