When the concealed intelligent switch connection power supply, smoke exhaust ventilator enters init state：Buzzer 9 plays booting sound
Happy, display screen 10 and press key lamp 12 are lighted 3 seconds.Subsequent smoke exhaust ventilator enters standby mode, display screen 10 and press key lamp 12
It is turned off, surface certain altitude is switched if being at this time placed in palm, and from switch left side stroke to switch right side, then intelligent switch
Interior first body-sensing circuit 6 and the second body-sensing circuit 7 sense the operation of human hand, and smoke exhaust ventilator is made to enter maximum power operation shape
State controls chip 2 and controls the prestissimo operating that relay 5 makes left and right motor with program setting, headlamp is with most strong brightness
Illumination, 10 display system information of display screen, all press key lamps 12 are all lighted.At this point, since press key lamp 12 is already on, use
Motor speed or illumination intensity etc. can be adjusted flexibly by touch key-press 8 according to actual conditions in person.When smoke exhaust ventilator uses knot
Palm need to be only placed in switch surface certain altitude by Shu Hou, user, from switch right side stroke to switch left side, the first body-sensing electricity
Road 6 and the second body-sensing circuit 7 just sense the operation of human hand, and control chip 2, which controls relay 5, keeps left and right motor out of service,
Headlamp is closed, and display screen 10 and all press key lamps 12 are turned off, and system is again introduced into standby mode.
During aforesaid operations, in order to realize the optimum operation effect to smoke exhaust ventilator, human body palm range switch surface
Height be 4cm.Switch may be opened by being climbed in view of biologies such as insects on smoke exhaust ventilator, the concealed intelligent switch designs at
The time that human body palm is drawn from switch side to the other side must be in 2 seconds.
Fig. 3 is the circuit diagram of the first body-sensing circuit 6 and the second body-sensing circuit 7 of the invention.According to Fig.3, first
