Sensitivity, and by finger can direct feel to air-flow, mountable multiple induction air outlets on a panel, it is not easy to operate
The situation of mistake, even people with visual impairment, which can also facilitate, to be operated.
Specifically, having detected whether that user is close by pyroelectric sensor, when no user is close, centrifugal fan is not opened
It is dynamic, avoid the waste of electric energy.
When finger incudes air outlet close to some, obstruction is generated to the air-flow that discharge pipe sprays, i.e. finger produces air-flow
A raw reaction force, the reaction force is through on airflow function to the pressure sensor being connected with discharge pipe, control circuit board root
According to the operation of the pressure value information identification user of pressure sensor, so that control switch be made to execute operation.
Corresponding 3 control switches of 3 pressure sensors can control 3 electrical appliances respectively, and make 3 pressure sensors simultaneously
It detects signal and passes through and judge that the size of each pressure sensor pressure value can also adjust the revolving speed of centrifugal fan, to adjust
That saves discharge pipe goes out wind velocity, and then is adjusted to sensitivity.Such as when original state, finger needs distance perception to answer air outlet
The pressure value that 1cm just can be such that pressure sensor detects is greater than setting pressure a, by increasing the revolving speed of centrifugal fan to improve wind
Speed, the pressure value that such finger distance perception answers air outlet 2cm that pressure sensor can be made to detect are greater than setting pressure a.In this way
The function that adjustment of sensitivity is increased in the case where additionally not increasing component facilitates user to be adjusted according to itself hobby
It is whole.
It further, can be by first specifying target when control switch is the rotation regulating switch by step motor control
Other two induction air outlet (pressure sensor) is then used as adjusting key to adjust by air outlet (i.e. corresponding electrical appliance)
Section stepper motor positive and negative rotation further enriches function of the invention to which rotation regulating switch be adjusted.
In addition, to adjust the distance between the hearth of kitchen ventilator, user can turn down oil by adjusting lifting kitchen ventilator
Smoke machine enhances the suction of kitchen ventilator.
