Abstract
The utility model discloses a capacitance type touch button which includes an acrylic housing, a pattern part, an IC control module, and a PVC box outer cover. The acrylic housing is in a circular structure, and is the outermost part of the entire capacitance type touch button. The pattern part is realized through photo printing with the help of the thermal transfer technology, and the pattern part is tightly attached to the back of the acrylic housing. The PVC box outer cover is fixed on the back of the pattern part. The IC control module is arranged in a PVC box, and one contact point of the IC control module is pasted on the center of the pattern part via an aluminium sheet. The capacitance type touch button takes the IC chip as the control core, and the service lifetime of the capacitance type touch button is over a million times. The housing is made of acryl and is provided with a photo, so the visual prompting capability is strong. Beside, the button can be provided with any pattern and character, so the capacitance type touch button is clear and visual.
Description
Technical field
The utility model relates to a kind of capacitance touch type button, relates in particular to the appearance formula touch button of showing in the exhibition of science popularization showpiece.
Background technology
At present; In the industry that the science popularization showpiece is showed, have no the touch button of the damage problem that can solve element in the button interaction system, and the useful life that general button can only reach is 5-15 ten thousand times; Useful life is shorter relatively; And the outward appearance of button is more stiff, and the visual cues ability is relatively poor, participates in directly perceived inadequately.。
The utility model content
For overcoming the prior art deficiency; The purpose of the utility model provides a kind of capacitance touch type button, uses the IC chip as the control core, reaches useful life more than 1,000,000 times; Shell takes to use acrylic to add the mode of description; The visual cues ability is strong, and can on button, do figure and font arbitrarily, accomplishes simple and clear.
The purpose of the utility model realizes through following technical scheme.
A kind of capacitance touch type button, it comprises acrylic shell, pattern part, IC control module, PVC box outer cover.Described acrylic shell is a circular configuration, and it is whole device outermost layer; Pattern part is to be realized by the description of producing through hot transfer technique, and the firm back side that is attached to the acrylic shell; PVC box outer cover is fixed on the back side of pattern part; The IC control module is arranged in the PVC box, and the central authorities at pattern part are pasted through aluminium flake in an one of which touch point.
This is practical, and electric charge in the human body will be accumulated through induction bonding pad, has changed the capacitance variations of the benchmaring induction point of IC itself newly through the touch of human finger, changes final module output switching value thereby cause controlling inner frequency.
The beneficial effect of the utility model:
1, use transparent acrylic as touch interface, make things convenient for the title of any layout in bottom surface and button, apparent size can require size immediately, and the surface is better through the polishing touch feeling;
2, long service life is non-maintaining, meets the more and bigger occasion of flow of the people of crowd;
3, the condenser type type is touch, does not have the mechanical action process;
4, easy for installation, non-maintaining.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.

Embodiment
A kind of capacitance touch type button, it comprises acrylic shell 1, pattern part 2, IC control module 3, PVC box outer cover 4.Acrylic shell 1 is a circular configuration, and it is whole device outermost layer, and its thickness is 10mm, and the specification of its radius is not waited by 30mm-200mm; Pattern part 2 is to be realized by the description of producing through hot transfer technique, and the firm back side that is attached to acrylic shell 1; PVC box outer cover 4 is fixed on the back side of pattern part; IC control module 3 is arranged in the PVC box 4, and the central authorities at pattern part 2 are pasted through aluminium flake in an one of which touch point.Appearance formula touch button is the touch through human finger, and the electric charge in the human body will be accumulated through induction bonding pad, has changed the capacitance variations of the benchmaring induction point of IC itself, changes thereby cause controlling inner frequency, final module output switching value.
Use 20 touch buttons in the plantation zoning exhibition of this exhibition section of the basic necessities of life of China national science and technology center, each button is represented a kind of crops, through touching the place of production of introducing this crop.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage that is familiar with this art can understand the utility model content and also implements, and can not limit the protection range of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection range of the utility model.
