[embodiment]
The present invention is described in further detail below in conjunction with accompanying drawing.
See also Fig. 2, the mobile phone 3 of preferred embodiment of the present invention comprises: mobile phone body 30, mobile phone lid 40, key panel 50.Mobile phone lid 40 is to be used to coat mobile phone body 30, and key panel 50 is between mobile phone lid 40 and mobile phone body 30.Wherein, key panel 50 provided by the invention comprises: substrate 520, button projection 540, photocatalyst layer 560.
Mobile phone body 30 comprises body wiring board 320 and a plurality of key contacts 340.Key contacts 340 is formed at the surface of this circuit board body, and corresponding and corresponding mobile phone body functional switch.When key contacts 340 is subjected to oppressing, can make the appropriate section conducting of the body wiring board 320 of mobile phone body 30, thus the on-off action of playing.Key contacts 340 can be the conductive rubber contact.
Mobile phone lid 40 is coated on the outside of mobile phone body 30, and size conforms to mobile phone body 30, is used to protect the body wiring board 320 of mobile phone body 30; in the present embodiment, mobile phone lid 40 is the upper surface shell of mobile phone 3, and it comprises: casing 420; display window 440, a plurality of key holes 460.Casing 420 is the main part of mobile phone lid 40, and its shape, size are corresponding with shape, the size of mobile phone body 30, can pass through fastening structure, and it is installed on the mobile phone body 30.Casing 420 can be made by alloy, plastic or other material.Display window 440 is formed on the casing 420, corresponding to the display screen of mobile phone body 30, it is protected.A plurality of key holes 460 also are formed on the casing 420, and its position is corresponding to the key contacts 340 of mobile phone body 30, and the button projection 540 of key panel 50 can be realized operating of contacts thus by stretching out in the respective keys hole 460.
Key panel 50 provided by the invention comprises: substrate 520, button projection 540, photocatalyst layer 560.Substrate 520 is rubber or plastic tab, comprises facing surfaces 522,524.Button projection 540 is formed on the surface 522 of substrate 520, and it comprises a contact-making surface (indicate), and this contact-making surface is pointed palp surface during for operation push-button.Button projection 540 can be made by silicon rubber or plastic raw materials, is generally column construction, and it can be integrally formed with substrate 520, also can be fixed on the surface 522 of substrate 520 by stickup.The metal coating that the surface of button projection 540 also can further form the coating of reference numerals symbol and be used to influence mobile phone texture.
In addition, those skilled in the art should understand that mobile phone provided by the invention also can be the mobile phone of other shape and structure, as clamshell phone.Key panel provided by the invention, especially the specific design of button projection as structure, shape, material, quantity and position distribution etc., also can have other change, not should with
Embodiment is exceeded.
Wherein, key panel 50 also comprises a photocatalyst layer 560, and in the present embodiment, photocatalyst layer 560 is formed at button projection 540.Its generation type comprises that the mode to spray, to soak or to be coated with makes photocatalyst layer 560 directly be formed at the surface of button projection 540, or before 540 moulding of button projection, the photocatalyst material is added among the raw material of fusion, with together moulding of button projection 540, make photocatalyst material be distributed in the inside of button projection 540 to form photocatalyst layer 560.Two kinds of generation types all make the photocatalyst material particle can be uniformly distributed in the photocatalyst layer 560.This photocatalyst layer 560 comprises titanium dioxide (TiO
2), zinc oxide (ZnO
x) to wait photocatalyst material, the preferable range of the grain graininess of these photocatalyst materials be the 15-50 nanometer.
The concrete form structure of photocatalyst layer 560 can not be named limit in addition with it, should decide on its concrete forming method.When adopt spraying, soaking or the mode of coating when making it be formed at button projection 540 surperficial, formed photocatalyst layer 560 is a two-dimensional structure; When photocatalyst layer 560 and button projection 540 are one-body molded, the photocatalyst material particle will be distributed in the block inside of button projection 540, and formed photocatalyst layer 560 can be considered a three-dimensional structure.
In addition, photocatalyst layer 560 also can be further forms on substrate 520, or only forms at the contact-making surface of button projection 540.Its generation type is identical with the mode that it is formed at button projection 540.
Key panel 50 is between mobile phone body 30 and mobile phone lid 40.The surface 522 of substrate 520 is near mobile phone lids 40, and is corresponding, and its another surface 524 is near mobile phone body 30.Button projection 540 can be by stretching out in the mobile phone lid 40 corresponding key holes, and its position is corresponding to the corresponding key contacts 340 of mobile phone body 30.When pressing keys projection 540, can oppress corresponding key contacts 340, can make the appropriate section conducting of the body wiring board 320 of mobile phone body 30.Accordingly, during operation push-button, the zone that finger is contacted is distributed with photocatalyst layer 560.
The operation principle of explained later photocatalyst layer 560.
When the photocatalyst layer 560 that is formed at button projection 540 was accepted illumination, when particularly accepting the UV-irradiation below wavelength 400 nanometers, the photocatalyst material of photocatalyst layer 560 was (as TiO
2, ZnO
x) with its surface hydrone and the oxygen molecule generation chemical reaction that contacts, generation hydrogen ion (H
+), hydroxide ion (OH
-) and oxygen radical.On the one hand, because the existence of the extremely strong free radical of redox ability, decomposition is attached to the harmful germ and the dirt of button projection 540, also destroys the condition that new harmful germ multiplies simultaneously, thereby suppress new harmful germ growth; On the other hand, the OH of reaction generation
-And H
+Can destroy and disperse the formation of water droplet, make the surface be difficult for forming water droplet, contact angle (Contact Angle) diminishes, thereby makes the surface of button projection 540 have Superhydrophilic (Super Hydrophilic Ability), and harmful germ and dirt are cleared up easily.Reach thus and make key panel 50 decontaminations easy to clean, the antibiotic effect of sterilization.
During cleaning, key panel 50 can be pulled down, accept earlier illumination separately,, thereby remove dirt, killing pathogenic bacteria comparatively up hill and dale again with the clear water flushing.Also can directly mobile phone 3 especially button projection 540 be exposed to irradiation under the light source, reach the purpose of local bactericidal scale removal, carry out simple and easy cleaning.
The particulate that can further add gold (Au) or platinum (Pt) in the photocatalyst material of photocatalyst layer 560 also can drop to the carbon monoxide (CO) around the mobile phone below the 30ppm, improves the effect of photocatalyst effect.
With respect to prior art, the present invention is used for photocatalyst material the key panel of mobile phone, utilize photocatalyst material under illumination condition with water and oxygen reaction, and have the function of decomposing dirt, kill bacteria, make that the key panel of mobile phone is easy to clean, sterilization is antibiotic.
