Description

The touch control type operation panel that is used for purifier

Technical field

The utility model relates to a kind of guidance panel, relates in particular to a kind of touch control type operation panel that is used for purifier.

Background technology

Touch technology can be divided into four kinds of resistance-type (Resistive), condenser type (Capacitive), acoustic wave (Surface Acoustic Wave) and optical profile types (Optics) etc. according to principle of induction.This wherein, the aspect of using with resistance-type and capacitance-type strain gauge is the widest again.

Resistance touch screen or Trackpad can be described as a maximum technology of present use amount, and its drive principle is to seek coordinate axis with the mode of voltage drop.When each voltage by a pair of 0.5V of the X-axis in the coordinate and Y-axis drives, if resistance touch screen or Trackpad are touched,, can produce voltage drop because the loop is switched on, controller then can calculate the shared ratio of voltage drop, further calculates corresponding coordinate axis then.

From the structural plane of resistance-type, common resistance-type upper strata is that the PET (plastic material polyethylene terephthalate) with ITO Coating (indium oxide tin film) works as material, and lower floor works as material with the PET of ITO Coating or glass.When general untapped state, two-layer up and down is to strut with insulator Spacer Dot (spacer insulator point), otherwise will produce the fixedly problem of every bit of cursor.

General resistance-type framework formula Film on Glass (film on glass), that is to say that the upper strata is the PET of ITOCoating, lower floor then is the general glass with ITO Coating, and its shortcoming is, if general glass in use staves accidentally, glass fragment can hurt the user.

For avoiding this unexpected the generation, the special a kind of safer framework PolyesterLaminated (polester laminate structural formula) that adopts of existing manufacturer, be that the upper strata still is the PET of ITO Coating, but lower floor then is PET, optical cement, the chemically reinforced glass (from top to bottom) of ITO Coating.This wherein, it is strong 3.4 times that chemically reinforced glass bears pressure than general glass anti-, so when chemically reinforced glass is still unfortunate when breaking, optical cement can whole layer coats the fragment of chemically reinforced glass, avoids fragment incised wound user.This just looks like that the sheathing paper of windshield is the same, only can not split and can break, the resistance-type panel security of this kind Polyester Laminated framework Film on Glass that surpasses just far away.

Capacitance type touch-control panel more then is a distinct technology with resistance-type.Capacitive framework is fairly simple, basically be based on ito glass, four jiaos of discharges at ito glass, form a uniform electric field on the surface, when the object that can conduct electricity, for example similarly be people's finger when touching contact panel, can siphon away some electric current of trace, the controller of back then can calculate the ratio that electric current is sucked away, and touches a little corresponding to X-axis in the coordinate and Y-axis information thereby calculate.

Compare with resistance-type, far surpass resistance-type because no matter condenser type gets life-span, operation high temperature, anti-UV (ultraviolet ray) and initial strength everyway ready at penetrability, hardness, accuracy rate, reaction time, touch-control, therefore the big more options of Touch Screen or Trackpad adopt condenser type at present.

Be used as 3C (the mandatory product certification of the China national) product of guidance panel compared to widespread use Touch Screen or Trackpad, purifier or other household products still adopt traditional push type button.In general, on purifier, be provided with when comprising the guidance panel of button, for the clear function (for example back washing, water outlet or the like) that indicates each button, often need to make earlier multicolour pattern film, and then paste to the button position of purifier with viscose with respect to each button.Yet after long-time the use, the guidance panel on the purifier (the particularly multicolour pattern on the button) is easy to lacquer or breakage, causes consumer's dislike or inconvenience.

The utility model content

Fundamental purpose of the present utility model is providing a kind of touch control type operation panel that is used for purifier, mainly utilize Touch Screen or Trackpad to replace traditional pressing button, only need applying light Touch Screen or Trackpad can reach the purpose of operation purifier, use for a long time, guidance panel (the particularly multicolour pattern on the button) still can keep original state.

Based on above-mentioned purpose, the touch control type operation panel that is used for purifier described in the utility model comprises housing, Trackpad, the panel layer of button pattern or luminous display surface is provided, circuit board.Described Trackpad touch when being available for users to this purifier of executable operations by, described circuit board is provided with the Trackpad driving circuit, this Trackpad driving circuit is electrically connected with the Trackpad formation, thereby according to the coordinate information that obtains from described Trackpad, drives the Control Component of purifier.
