When the first single (four) 23 is in the closed state, the temporary chamber is in communication with the rear portion of the chamber 213. In addition, the inhaled drug release device 2 further includes a mouthpiece μ which is disposed at the output port 212 of the housing 21 and is detachable by the user, and is connected to the front section of the chamber 213 of the case _ and can be used A Bacterial filter 25 of bacteria in the helium gas, and a first indium i) and a first early-direction valve 26. The mouthpiece 24 has a passage 241 that communicates with the chamber 213 and the outside. The gas inlet member 25 has an input end 251 fixed to the casing and communicating with the chamber 213, an output end 25 2 opposite to the input end 251, a port 252 and an input end 251 and an output end 252. Between the layers 253. The aforementioned second check valve % controls the on and off of the gas passage 25 and the chamber 213. As shown in Fig. 23, in use, the user needs to have the mouthpiece μ and activate the control valve 31 to open it. At this time, the medicine in the drug reservoir 3 is sprayed into the casing 21 at a high speed via the nozzle 32. In the chamber 213, the atomization effect can be generated by striking the inner wall surface of the casing 21, and the atomized medicine will be diffused into the temporary chamber 223 by the rear portion of the chamber 213. When the user inhales, the chamber 213 The front section generates a negative pressure force to attract the first one-way valve 23 to open in the flow direction of the airflow, so that the atomized medicine can pass through the first check valve 23 from the temporary chamber 223 and the rear section of the chamber 213. The air outlet of the air permeable portion 222 of the cover 22 allows the air to enter and exit the cover 22, thereby balancing the internal and external pressures, thereby preventing excessive generation of the chamber 213 and the temporary storage chamber 223. Negative pressure is therefore easier and less laborious for the user to inhale the drug. In addition, as shown in FIG. 4, when the user exhales, the first check valve 23 1285120 is pushed by the positive pressure of the exhaled airflow to form a closed state, and the second single 26 is instead positively pushed by the exhaled airflow. Opened away from the u bite ^, so that the exhaled air can be input to the helium by the input end 251: 'After passing through the filter layer 253, the action is discharged by the input (4) 252 to the user who has infectious respiratory diseases. In other words, it filters bacteria more effectively and prevents the spread of bacteria. As shown in FIG. 5, in addition, the inhaled drug release device 2 of the present invention can be carried by the user as described above. For example, when used in a medical institution, the mouthpiece 24 can be replaced by a mask 27 as the case may be. The medicine device 3 can be further provided with an output joint 33'. At this time, the liquid medicine can be accommodated in the medicine storage device 3. When used, the output of the high (four) gas equipment 4 (of course, an air source) can be used in the medical institution. The f-way is engaged with the output joint 33 of the accumulator 3, «, the cover 27 is placed at the mouth and mouth of the user, and is input into the accumulator 3 at high speed by high-pressure oxygen, and is generated at the nozzle 32 under the action of the cypress effort. The liquid medicine is sucked into the high-speed gas by the negative pressure, and the high-speed sprayed into the rear section of the chamber 213 of the human shell, and the atomization effect can be generated by hitting the inner wall surface of the casing 21, thereby diffusing to the temporary storage S 223 Therefore, when the user inhales, the first turn 23 is opened due to the negative pressure, and the atomized medicine can also be output through the first check valve 23 from the output port 212 for the user to effortlessly Inhalation (as shown in Figure 6). As shown in FIG. 7, when the user exhales, the first check valve 23 forms an OFF state and the second check valve % is instead pushed by the positive pressure of the exhaled airflow toward the casing 21 away from the 21 Turning on, therefore, the exhaled airflow can be filtered by the second check valve 26, the gas member 25, and then discharged to the outside by the output terminal 252. So for some people with infectious respiratory diseases
