The body assembly B includes a first casing 3, a control module C and a sensor S disposed in the first casing 3. The accommodating component A is detachably disposed on the body component B, and the accommodating component A includes a second casing 4 and an atomizing module E. The nozzle assembly N is detachably disposed on the accommodation assembly A.

5 to FIG. 8, which illustrate an atomizer D including a nozzle assembly N according to the present invention. 5 and FIG. 6 illustrate that the hollow pipe fitting 2 of the nozzle assembly N is disposed on the outer surface 102 of the nozzle set 1; and FIG. 7 and FIG. 8 illustrate that the hollow pipe fitting 2 of the nozzle assembly N is disposed on the inner surface 100 of the nozzle set 1.

In detail, the atomizer D of the present invention uses the aforementioned nozzle assembly N, and the atomizer D includes a body assembly B, a receiving assembly A, and the aforementioned nozzle assembly N.

The body assembly B includes a first casing 3, a control module C and a sensor S disposed in the first casing 3. The control module C and the sensor S are electrically connected to each other.

The accommodating component A is detachably provided on the main body component B, and the accommodating component A and the main body component B can be disassembled and assembled with each other. The accommodating component A includes a second casing 4 and an atomizing module E disposed in the second casing 4. Similarly, the atomizing module E is detachably disposed in the second casing 4 and is electrically connected to the control module C.

The nozzle assembly N is detachably disposed on the accommodation assembly A, and the nozzle assembly N includes a nozzle set 1 and a hollow pipe 2. The hollow pipe fitting 2 can be disposed on the outer surface 102 or the inner surface 100 of the nozzle kit 1. For the feature description and setting method of the nozzle kit 1 and the hollow pipe fitting 2, please refer to FIGS. 1 to 4, which will not be repeated here.

As mentioned above, the hollow pipe 2 of the nozzle assembly N of the atomizer D of the present invention has a connection opening 22 and a detection opening 21. As described above, the connection opening 22 of the hollow pipe 2 in this embodiment is connected to the sensor S provided in the body assembly B, and the detection opening 21 is close to the ejection opening 11 of the nozzle set 1. When the user puts his lips on the nozzle assembly N of the atomizer D and performs an inhalation operation, the detection opening 21 and the ejection opening 11 generate a negative pressure. The sensor S disposed in the body assembly N detects the change in the air pressure of the detection opening 21 through the gas flow in the hollow pipe 2. Since the pressure change of the discharge opening 11 is equal to the pressure change of the detection opening 21, the pressure change of the detection opening 21 that can be detected by the sensor S can be regarded as the pressure change of the discharge opening 11 of the nozzle assembly N.

It is worth mentioning that, in the atomizer D of the present invention, the sensor S is disposed in the first casing 3 of the body assembly B and is electrically connected to the control module C. Therefore, whether the hollow pipe member 2 of the nozzle assembly N is disposed on the inner surface 100 or the outer surface 102 of the nozzle set 1, the pipe body thereof extends to the inside of the body assembly B. In other words, the hollow pipe 2 of the present invention does not pass through the second housing 4 of the receiving assembly A, but is straight.

As mentioned above, the nozzle assembly N of the atomizer D of the present invention has a hollow pipe 2, and the connection opening 22 is connected to the sensor S in the body assembly B. The sensor S can detect the pressure change of the detection opening 21 through the hollow pipe 2 and convert it into a sensing signal to transmit its sensing signal to the control module C also disposed in the body component B. Then, the control module C sends a control signal according to the sensing signal, thereby controlling the activation of the atomization module E containing the component A to perform an atomization operation. In actual application, the initial nebulizer D is not activated. When the user holds the lips against the nozzle assembly N and performs an inhalation action, the internal space of the nozzle assembly N (including the ejection opening 11 and the detection opening 21) The gas flows to the mouth of the user, and thus generates an outward negative pressure for the nozzle assembly N. The sensor S senses the negative pressure to generate a negative pressure signal, and transmits the negative pressure signal to the control module C. The control module C generates an activation signal according to the negative pressure signal, and transmits the activation signal to the atomizing module. E. The atomizing module E receiving the activation signal performs an atomizing action to atomize the liquid medicine in the component A, and actively delivers the atomized drug component to the user's body, or The chemical component can also be passively inhaled by the user according to the user's inhalation action.

In contrast, when the user stops the inhalation action or moves his lips away from the nozzle assembly N, the gas inside the nozzle assembly N does not flow, so the sensor S fails to sense the pressure change, so no negative pressure signal is provided to In the case of the control module C, the control module C provides a stop signal to the atomizing module, so that the atomizing module E stops the atomizing operation.

With the foregoing arrangement, the nebulizer D of the present invention can provide a controlled amount of drug atomization when the user actually inhales, and when the user stops inhaling, the atomization of the drug can be stopped immediately. This can give users a precise amount of medicine and improve High drug utilization.
