Detailed description of the invention
First embodiment
As shown in Figure 1, the present embodiment illustrates for soft-touch control, including circuit board 10, at least one first button 11 on circuit boards is set, and receives the controller 12 that any one first button 11 operates signal and sends the first control signal corresponding to this first button. Described first button 11 is carry, to controller, the button making electrical equipment carry out opening or closing signal, and namely functionally, the first button 11 is the energising or power-off that are used directly to and control electrical equipment. First button 11 is touch key-press, and touch key-press is capacitance type touch key and/or resistive touch button, it is preferable that touch key-press is capacitance type touch key. When there being finger that the first button 11 is carried out pressing operation, first button 11 itself is have certain capacitance (Cp), the finger of people is once touch the first button 11, owing to the finger of people also has corresponding electric capacity (Cf), as in figure 2 it is shown, therefore controller 12 can detect the additive value (Cx) of the electric capacity of the electric capacity on staff and the first button 11.
Cx=Cp+Cf formula 1
By detecting this change, will know that and whether have finger close, as in figure 2 it is shown, the capacitance detected by controller is significantly raised when touching the first button 11.
As shown in Figure 3, described circuit board 10 is provided with anti-interference electrode 13, this anti-interference electrode 13 electrically connects with controller 13, described anti-interference electrode 13 is in latticed, and it is distributed in the first button 11 around, anti-interference electrode 13 adopts the conducting metal such as copper or aluminum to make, it is preferred to copper, and anti-interference electrode 13 forms an electric capacity.Owing to have employed 6 the first buttons 11 in the present embodiment, latticed anti-interference electrode 13 is equivalent to be provided with 6 holes, and each hole is that the first button 11 is stepped down, so that the first button 11 is not covered by anti-interference electrode 13. after being provided with anti-interference electrode 13, the interference that switch is formed by one harmonic wave that can filter the external world, if the position that two these soft-touch controls are installed is in such as kitchen or the bigger place of toilet relative humidity, if aqueous vapor enters in switch, due to the first button 11 selection is capacitance type touch key, therefore, after first button 11 and interference electrode 13 are partly or entirely covered by aqueous vapor, electric capacity is formed between aqueous vapor and the first button 11, at this moment, the change of the capacitance that controller 12 can be detected simultaneously by the first button 11, and the capacitance of anti-interference electrode 13 be changed to Cy, controller 12 is internal passes through algorithm, namely Cy is deducted with the Cx in above-mentioned formula 1, when the difference of gained is if less than the value set, then think interference signal, when the difference of gained is if greater than the value set, then it is judged to manual operation signal, significantly, after anti-interference electrode 13 is set, on the first button 11 and anti-interference electrode 13 surface so long as not water, but aqueous vapor, such structure is can be undertaken filtering by the interference of aqueous vapor, greatly reduce the probability by mistake controlled.
Described controller 12 can be the controllable type device of single-chip microcomputer, DSP or MCU mono-class, and in the present embodiment, what controller 12 adopted is single-chip microcomputer.
As shown in figures 1 and 3, also including the second button 14 arranging on the circuit board 10 and electrically connecting with controller 12, the second button is touch key-press, and touch key-press is capacitance type touch key and/or resistive touch button, preferably, touch key-press is capacitance type touch key. after controller 12 receives the operation signal coming from least two the first button 11, or after controller 12 receives the operation signal coming from the second button 14 and at least one the first button 11, or after controller 12 receives the operation signal coming from the second button 14, controller sends the second control signal, this second control signal can be regulate signal, for regulating the some degree of certain lamp, or switching signal, such as lighting the LED backlight being arranged on switch, or timing signal, such as it is used for making the work of certain electrical equipment how long and is automatically switched off etc., in a word, user can be configured as required, and user is when buying, the functional requirement of oneself only need to be described to manufacturer, manufacturer can produce according to the demand of user. for self arrangement on the circuit board 10 of the second button 14, it is preferable that the head end of the second button 14 is connected with tail end and surrounds into an annular section, and all first buttons 11 are in the annular section that the second button is surrounded. described annular section be except install controller 12 or to should have controller 12 region (when controller 12 and the second button 14 install face on the circuit board 10 be not same time, at this moment just for except installation to the region that should have controller 12).
For the mode that aforesaid operations the second button and/or the first button send the second control signal, specifically, operator can touch the surface of whole switch with whole palm, palm covers the operation control surface of whole switch, this mode can form electric capacity Cx1 between each the first button and palm, forming electric capacity Cz1 between second button and palm, can form electric capacity Cy1 between anti-interference electrode and palm, final capacitance meter formula is:
C=Cx1+Cx2+Cx3+Cx4+Cx5+Cx6+Cz1-Cy1Formula 2
According to rational setting, for the result of above-mentioned formula 2, the capacitance of gained can more than setting value, so that it is manual operation signal that aforesaid operations signal is judged to, so, when controller receives the input signal of the first button 11 and the second button 12 at the same time, the second control signal is sent.
Operator can also touch two or more first button 11 with finger simultaneously, or first touch the second button 14 with finger, then touches the first button 11, or touch the second button 14 simultaneously and touch the first button 11, and final capacitance meter formula is:
C=Cx1+Cx2+ ... Cxn formula 3
C=Cx1+Cz1Formula 4
Formula 3 is touch the capacitance meter formula of two or more first button 11 simultaneously, wherein, n be include more than 3 natural number.
Formula 4 for first touching the second button 14 with finger, then touches the first button 11, or touch the second button 14 simultaneously and touch the capacitance meter formula of the first button 11.
Furthermore it is also possible to adopt any one side of soft-touch control, or pinch any two side of switch with two fingers of a hands, touch so that the second button 14 is formed,
Second embodiment
As shown in Figure 4, this utility model is not limited to above-mentioned embodiment, and described second button 14 is multiple and in strip, these second buttons are identical with the arrangement of above-mentioned first embodiment, simply not surrounding the region of a Guan Bi, certainly, its arrangement can also be other forms. All the other structures are same with the first embodiment party, do not repeating at this.
3rd embodiment
As it is shown in figure 5, this utility model is not limited to above-mentioned embodiment, the second button is multiple and in the form of a ring, all around second button outside each first button. All the other structures are same with the first embodiment party, do not repeating at this.
In addition to the embodiments described above, the first button and the second button can also adopt mechanical button, for instance touch key.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in claims of the present utility model.
