When switch is pressed, with this sensor contacts, sensor, when detecting with the first switch contact, determines that the state of the first switch is
Open, then send wake-up signal to detection device；When the first switch is extracted, switched to non-connecing with this sensor by contact condition
Touch state, sensor detect with first switch switched to contactless state by contact condition time, to detection device send stop
Dormancy signal.
Refer to Fig. 7, the embodiment of the present invention additionally provides a kind of operation based on any of the above-described described medical liquid atomizing equipment
Method, the method may comprise steps of:
Step 701: by the first switch open of described medical liquid atomizing equipment.
Wherein, the first switch is the first order switch of medical liquid atomizing equipment, and only after the first switch open, second opens
Pass can be triggered.
Step 702: utilize detection device detection to act on the inspiratory airflow of the suction end being atomized pipeline, according to described air-breathing
The size of air-flow, controls the state of second switch.
When the suction end being atomized pipeline is provided with suction nozzle, user can bite suction nozzle, carries out aspiratory action with mouth, detection
Device can detect the inspiratory airflow of user.
When the suction end being atomized pipeline is provided with face shield, face shield can be covered mouth and nose, and carry out air-breathing with mouth by user
Action, detection device can detect the inspiratory airflow of user.
User, when utilizing atomizing type treatment respiratory tract disease, is to need to be drawn in bronchus the medicinal liquid of atomization,
Respiratory tract disease effectively can be treated, and being drawn in bronchus by the medicinal liquid of atomization is to need user deeply to exhale
Can realize during suction action, therefore, in the present embodiment, a signal threshold value can be set, utilize this signal threshold value to determine
Whether user is carrying out deep breathing action.
Wherein it is possible to utilize signal threshold value to proceed as follows, to realize the control to second switch:

When opening state and trigger signal less than signal threshold value, close second switch.
When triggering signal and reaching signal threshold value, show that this user is carrying out deep breathing action, it is possible to achieve having of medicinal liquid
Effect sucks, thus opens second switch.Time under second switch is in opening, detect that triggering signal is less than signal threshold
Value, shows that the aspiratory action of user completes, now user may carry out expiration action, it is impossible to carry out effective suction of medicinal liquid
Enter, therefore can close second switch.
Step 703: trigger nebulizer when second switch is opened and medicinal liquid is atomized.
Owing to the nebulizer in medical liquid atomizing equipment can be ultrasound atomizer, it is also possible to be compressed air type nebulizer,
By second switch is attached with nebulizer, nebulizer is triggered second switch, so that nebulizer is by medicinal liquid
Be atomized, the medicinal liquid after atomization can from atomization pipeline suction end ejection, with ensure user can suck atomization after medicine
Liquid.
Below as a example by this nebulizer is as ultrasound atomizer, medicinal liquid is atomized by nebulizer in the embodiment of the present invention
Flow process illustrates.
Step A1: when described second switch is opened, triggering electric energy provides device to provide electric energy for ultrasound wave maker；
