Example description.
The first layout type of induction electrode 3 and its application：
As shown in Fig. 2, the quantity of induction electrode 3 is one, it is preferably disposed on the middle part of control panel 2.When induction electrode 3
When quantity is one, achievable operating gesture may include clicking every sky, every empty long-press etc., and induction electrode 3 also has inspection
Survey touch function.
Can be realized by functions such as above-mentioned operating gesture, touch detections smoke exhaust ventilator is switched, wind turbine turns
Speed control, the brightness of headlamp control etc..For example, smoke exhaust ventilator switch both can by operating gesture every sky click or every
Empty long-press is realized, and e.g., smoke pumping can be realized to be touched to induction electrode 3 by being realized to the touch of induction electrode 3
For the switch of machine, when human contact is to induction electrode 3, the capacitance value data of autonomous induction is sent to capacitance by induction electrode 3
Induction chip 4 carries out digital-to-analogue conversion, and then electric capacity chip 4 controls unit during the capacitance value data after digital-to-analogue conversion is sent to second
5 are analyzed, when the capacitance value data that induction electrode 3 is touched is located in the threshold value that preset smoke exhaust ventilator is turned on and off
When, control unit 5, which passes through, in second controls unit 1 and sends instruction in communication unit 6 to first so that control the control of unit 1 in first and take out
The wind turbine of kitchen ventilator is turned on and off.
In another example the brightness of the rotating speed or headlamp of wind turbine can be clicked every sky by operating gesture, every empty long-press come
It realizes, it e.g., can be by select the unit for needing to adjust every the operating gesture clicked of sky, you can by being clicked pair every sky
The unit controlled switches over, i.e., selects to carry out control to wind turbine by clicking every sky or be carried out to headlamp
Control.Then, it can be adjusted come the brightness of rotating speed or headlamp to wind turbine by the operating gesture every empty long-press, e.g., when
By every sky click selection the rotating speed of wind turbine is adjusted after, by every empty long-press come improve wind turbine rotating speed or reduce wind turbine
Rotating speed；And the switching of the rotating speed of wind turbine increased or decreased can by being defined every the operating gesture of empty long-press, e.g., if

The operation object of the operating gesture of sliding is switched over.And the third layout type of induction electrode 3 can then remove switching from
Step, as shown in Figure 4, it is assumed that when needing the rotating speed to wind turbine to be adjusted, human body can be made to pass through two in vertical direction
The adjusting to the rotating speed of wind turbine can be realized in the sliding that different order is carried out between induction electrode 3；Simultaneously, it is assumed that when needing to compare
When the brightness of bright lamp is mediated, human body can be made by carrying out different order between two induction electrodes 3 in the horizontal direction
Sliding the adjusting to lighting brightness can be realized.
Furthermore the third layout type of induction electrode 3 with horizontal sliding action and vertical sliding other than it can be operated, also
The operating gesture rotated clockwise or counterclockwise every sky in plane can be carried out, it e.g., can be by every the empty clockwise or inverse time
Needle rotation operating gesture come control wind turbine rotating speed, headlamp brightness either cleaning systems degree of cleaning etc., again
Excessive repeat just is not made.

As shown in figure 5, the quantity of induction electrode 3 is three or more, multiple induction electrodes 3 are located on same line.With induced electricity
Second of layout type of pole 3 and its application compare that difference lies in the tools of the induction electrode 3 on same line there are three more than, make
When proper progress slide, sliding control accuracy can higher.
For example, when the quantity of the induction electrode 3 on same line is three or more, it is assumed that when needing to the bright of headlamp
When degree is adjusted, realized to headlamp not by controlling different sliding sequences and slipping over the induction electrode 3 of different number
With the adjusting of the brightness of gear so that the range of the brightness regulation of headlamp is wider, precision higher.
In addition, when the quantity of the induction electrode 3 on same line is four or more, it can also be by same line
On induction electrode 3 carry out division region so that multiple induction electrodes 3 in each region can have independent control work(
Energy.Such as, it is assumed that when the quantity of the induction electrode 3 on same line is six, six induction electrodes 3 can be divided into two controls
Region so that first to third induction electrode 3 is a control area, and the 4th to the 6th induction electrode 3 is another
A control area, and the two control areas can be set as the brightness of the rotating speed, headlamp to wind turbine respectively and be adjusted.
Furthermore regardless of induction electrode 3 is which kind of above-mentioned layout type, each induction electrode 3 in each layout type
It may have individual touch control function.Preferably, induction electrode 3 may include the induction electrode of pcb board formula, spring
Induction electrode, the induction electrode of copper foil formula or the induction electrode of electro-conductive glass formula.Wherein, the induction electrode of pcb board formula is main
