control mode 1

When the user is in a stable breathing state

The working time of the atomizer is set according to the breathing frequency of a user, the working state of the atomizer is synchronous with the inspiration action of the user, when the user inhales, the atomizer starts to work, the generated foggy liquid medicine is inhaled into a diseased part along with the inspiration action of the user, when the user exhales, the atomizer stops working, and the situation that the generated foggy liquid medicine is blown out of a suction nozzle by the airflow exhaled by the user to cause the waste of the liquid medicine is avoided.

In this embodiment, the operating state of the nebulizer is set by measuring the breathing frequency of the user, for example, when the user inhales for 5 seconds, the operating time of the nebulizer is set to 5 seconds, the user holds the breath for 2 seconds, and exhales for 1 second, the time for the nebulizer to stop operating is 3 seconds, and when the nebulizer operates, the nebulizer stops 3 seconds after 5 seconds of operation, and then operates for 5 seconds, and the operation is circulated in sequence.

For example, if the inhalation time of some users is short, the operating time of the nebulizer is set to 3 seconds, the breath is held for 2 seconds, the exhalation is fast for 1 second, the time for stopping the nebulizer is set to 3 seconds, the nebulizer stops operating for 3 seconds every 3 seconds, and the nebulizer does not output atomized liquid medicine when in a stopped state.

In the using process, due to the change of the breathing frequency of the user, the inspiration action is asynchronous with the working state of the atomizer, the expiration can be adjusted again through the pause key of the controller, when the inspiration is started, the atomizer is started to work again according to the set time, and for example, when the time of the user is prolonged or shortened, the working time of the atomizer can be adjusted through the time adjustment key of the controller.

In this embodiment, the housing of the controller is provided with an operating time setting button for modifying the mist generating time of the atomizer in an increasing or decreasing manner, and a setting button and a pause button for stopping the operating time for controlling the operating state of the atomizer.

Control mode 2

When the user is in a state of breathing unsmooth.

The atomizer keeps working state and continuously outputs atomized liquid medicine.

The above contents are only for explaining the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby, and any modification made on the basis of the technical solution according to the technical idea of the present invention all fall within the protection scope of the claims of the present invention.
