The cover 24 is movably coupled to the barrel 21 and covers the cavity 210. In actual use, the user can open the flip-top 24 and fill the liquid medicine into the cavity 210 for atomization, so as to provide the user with the liquid medicine atomized in the cavity 210 inhaled from the nozzle 22. The structure of the nozzle cartridge 20 will be described in more detail below.

Fig. 3 to 5 are a schematic exploded view, a schematic external view and a cross-sectional view of a nozzle barrel according to the present application. As shown in fig. 3, the cylinder 21 includes a housing 210, an exhaust chamber 211, an air flow passage 212, and a chemical solution discharge hole 213. The sensing structure 23 is disposed in the exhaust cavity 211. The nozzle 22 is disposed at one side of the cylinder 21 and communicates with the chamber 210. The nozzle 22 communicates with the exhaust chamber 211 through the flow channel 212, and the nozzle 22 communicates with the chamber 210 through the liquid medicine discharge hole 213. The cylinder 21 further includes a liquid medicine leakage plate 214 disposed at a bottom side of the cavity 210, and the liquid medicine leakage plate 214 is connected to the liquid medicine discharge hole 213. Accordingly, the liquid medicine atomized in the chamber 210 may flow toward the liquid medicine discharge hole 213 to enter the nozzle 22 by being guided by the liquid medicine leakage plate 214.

In this embodiment, the nozzle cartridge 20 further includes an atomization sheet 25. The atomizing plate 25 is disposed at one side of the liquid medicine discharging hole 213, thereby filtering foreign substances such as impurities that may flow into the cavity 210 from the nozzle 22 when a user exhales. The atomizing plate 25 also has functions of vibration atomization, prevention of outflow of a chemical solution, and the like.

Furthermore, the sensing structure 23 includes a shielding rod 231, a swinging member 232 connected to the shielding rod 231, and a positioning seat 233, and the shielding rod 231 is disposed corresponding to the position of the sensor 13. The shade bar 231 includes an extension arm 2311 and a shade piece 2312. The positioning seat 233 is coupled to the cylinder 21. The swinging member 232 includes a rotating shaft 2321 and at least one blade 2322 connected to the rotating shaft 2321. The rotating shaft 2321 is rotatably disposed on the positioning seat 233. The at least one blade 2322 protrudes out of the positioning seat 233. In addition, one end of the extension arm 2311 is connected to the rotating shaft 2321, and the other end is connected to the mask 2312 and protrudes out of the positioning seat 233 to be located above the sensor 13.

It should be noted that the blade 2322 is a thin sheet made of a soft material, and the blade 2322 can be blown by air to rotate and swing around the rotation axis 2321.

Specifically, the cylinder 21 includes a pair of hooks 215 disposed on the liquid medicine leakage plate 214 and outside the cavity 210. The positioning socket 233 is coupled in the exhaust chamber 211 by the pair of hooks 215.

It is further noted that the nozzle cartridge 20 further includes a conductive spring 26. The conductive spring 26 is disposed at the bottom of the cylinder 21. When the host 10 is assembled to the bottom side of the nozzle barrel 20, the conductive terminals 122 of the host 10 are electrically connected to the conductive clips 26.

Please refer to fig. 6 to 8, which are schematic diagrams of an operation, a gas flow path, and cross-sectional views of the nebulizer with the sensing structure during exhalation according to the present application. As shown in the figure, when the user exhales, the gas blown from the nozzle 22 flows into the cylinder 21 and blows the swinging member 232, thereby driving the shielding rod 231 to trigger the sensor 13. In more detail, the gas blown from the nozzle 22 during exhalation flows into the exhaust chamber 211 from the gas flow channels 212 on both sides of the cylinder 21, and blows the swinging member 232. At this time, the blade 2322 swings around the rotation shaft 2321, and drives the shutter rod 231 to turn. In addition, the mask 2312 of the mask bar 231 leaves the sensing range of the sensor 13, thereby triggering the sensor 13 and sending out a sensing signal.

It should be noted that the sensing signal sent by the sensor 13 is transmitted to the sensing circuit board 121, and further transmitted to the control module 12, so as to achieve the function of detecting the exhalation of the user. Accordingly, when the sensor 13 senses the exhalation of the user, the control module 12 controls to stop the atomization of the liquid medicine, thereby preventing the waste of the liquid medicine and improving the administration efficiency.
