The technical solution of the utility model is described in further detail with reference to the accompanying drawings and detailed description.
The present embodiment illustrates so that household electrical appliance are kitchen hood as an example, and kitchen hood includes touch controlled key group
Part.Certainly, household electrical appliance can also be other types, such as, TV, air-conditioning, micro-wave oven, electric cooker etc. be in the utility model
Protection domain within.
As Figure 1-3, the touch controlled key component of the present embodiment include panel 1, encapsulated layer 2, sensor 3, controller 4,
Box body 5 and filler 6.Each part is illustrated respectively below：
Panel 1, it is the panel of kitchen hood.Because metal decking has the property more excellent than the panel of other materials
Can, thus, it is preferable to using metal decking, certainly, panel 1 can also be the panel of other materials.
Some touch-control marks 11 are provided with panel 1, touch-control mark 11 has certain area and mark, for guiding
User carries out touch-control to touch-control mark 11.Generally, touch-control mark 11 has a border circular areas, and in the border circular areas
With mark, such as：Start mark, shutdown mark, air quantity mark, illuminating lamp mark etc..
Encapsulated layer 2, encapsulated layer 2 are located at the inner surface of panel 1 and contacted with the inner surface of panel 1.Encapsulated layer 2 is used to encapsulate
Sensor 3, encapsulated layer 2 are used to the vibration on panel 1 being transferred to sensor 3.
Encapsulated layer 2 is the soft materials that can transmit vibration, for example, silica gel buffer thin film, encapsulated layer 2 or use
The encapsulated layer 2 that PCB seal pressures Shooting Technique is formed.Certainly, the utility model encapsulated layer 2 is not limited in above two material
Material, every material that can transmit vibration, within the scope of protection of the utility model.Encapsulated layer 2 preferably passes through stickup
Mode is fixed on the inner surface of panel 1.
Sensor 3, sensor 3 are the vibrating sensor for detecting vibration signal.
Vibrating sensor includes vibrating diaphragm, silicon back pole plate, capacitance-voltage conversion circuit and signal amplification circuit, and vibrating diaphragm is carried on the back with silicon
Electric capacity is formed between pole plate.Vibrating sensor be using vibration change caused by barometric gradient make vibrating diaphragm be stressed interference and produce
Deformation, and then change the capacitance between vibrating diaphragm and silicon back pole plate, the change of capacitance is converted into by capacitance-voltage conversion circuit
The exporting change of magnitude of voltage, then export voltage amplification caused by sensor by amplifying circuit, so as to which vibration signal be converted
Into voltage signal.The resistance of a high impedance is used to provide a bias voltage VPP for the electric capacity that vibrating diaphragm and silicon back pole plate are formed,
So as to producing fixed charge on electric capacity, the voltage of sensor output is directly proportional by the deformation to VPP and vibrating diaphragm.
Each touch-control mark 11 at least corresponds to three sensors 3, and touch-control mark 11 senses positioned at corresponding to touch-control mark 11
