The air inlet grid 11 is internally provided with filter cotton, and the filter cotton can purify air entering the portable respirator. The shrinkage cavities are used for gathering the air entering from the air inlet grid 11 and enabling the air to flow into the portable respirator from the shrinkage cavities. The throughbore 12 is used for passage of an output conduit to direct humidified air within the portable ventilator to the patient end. The opening 13 is used for placing a human-computer interaction interface of the control main board 20, so that an operator can complete control operation on the portable respirator through a touch screen. The handle 14 is arranged to make the portable respirator portable. The memory tolerance slot 15 can be used for placing an SD card and the like to record and store the air flow, the working time and the like of the portable respirator.

The control main board 20 includes a touch screen panel 21 for man-machine interaction. The touch screen panel 21 is disposed in the opening 13, so as to facilitate human-computer interaction. The control main board 20 may further include a knob for adjusting the pressure in the blower chamber 30, a button for adjusting the airflow rate of the humidified air exiting from the output duct, a start-stop button, and the like. The control board 20 is a conventional technology, and is composed of a plurality of electrical components, such as a CPU, a memory, an amplifier, a single chip, a PLC, etc., which are well known to those skilled in the art and will not be described herein.
