Referring mainly to fig. 4, in an embodiment, a retaining tube 121 forming a gas channel 120b and a return channel 120e surrounding the retaining tube 121 are disposed in the adaptor 120, the return channel 120e is communicated with the heating chamber 120a, the axial cross section of the return channel 120e is trapezoidal, and the width of one end of the return channel 120e near the heating chamber 120a is smaller than the width of the other end of the return channel 120 e.

The medicine feeder changes the movement track of the gas medicine by arranging the gas channel 120b in the adapter 120 to communicate the heating cavity 120a with the heating cavity 130a above, namely, the gas medicine is sprayed from the conical divergent shape to the periphery to flow upwards in a cylindrical shape, and directly flows to the heating cavity 130a above, thereby playing the roles of limiting and guiding flow, and reducing the mass aggregation of the gas medicine to liquefy. In addition, since the axial cross section of the return channel 120e is trapezoidal (i.e. the return channel 120e is funnel-shaped), a small amount of generated liquid medicine can flow back to the heating sheet 202 along the inner wall of the return channel 120e and be vaporized again, thereby improving the utilization rate of the liquid medicine.

It should be noted that, the existing drug delivery device in the market generally only heats and vaporizes once through the heating element 20 and then directly sucks the drug gas through the suction nozzle 131, so that the drug gas at normal temperature is sucked by human body to be choked, which can cause cough. In the utility model, the gas medicine generated by the heating component 20 reaches the heating cavity 130a through the gas channel 120b and is heated again by the heating component 30, so that the gas medicine inhaled by a person after heating can not generate rejection reaction, and the experience is enhanced.
