Description
Technical field:
The utility model relates to a kind of touch controlled key device that is used for cooking furnace, and particularly a kind of touch controlled key device that is used on the electromagnetic oven belongs to the renovation technique of cooking furnace device of pushbutton.
Background technology:
Along with the progress of society, the use of various household appliances also more and more widely, the control of household appliances and use and all to realize by the human-computer interaction device.The man-machine interactive operation occupation mode great majority of existing household appliances are following two kinds of manual type operation schemes: a kind of is the touch-switch button, what it mainly used is mechanical button, by pressing keys, make the mechanical part conduction, produce the input that change in voltage is finished control signal.Another kind is direct charge inductive type button, and it utilizes human body self institute static electrification, by conduction button conduct charges, and utilizes the variation of the electric charge induction circuit inductance quantity of electric charge, with the input of control signal.These two kinds of schemes all in various degree exist following defective: for light touch switch type key, it is mainly realized by mechanical connecting structure, repeatedly use and be easy to generate aging, the wearing and tearing of mechanical connecting structure, even situation such as loose contact, and be subjected to the restriction of structural member easily, because the connection of the most fit structure spare of mechanical button is operated, when the structural member design was unreasonable, not firm, processing ease lost efficacy; And,, being easy to generate misoperation because electric charge directly is sent on the electromagnetic induction circuit by the conduction key component for the charge inductive type button, reliability is not high.
The utility model content:
The purpose of this utility model is to consider the problems referred to above and a kind of high touch controlled key device of control reliability of operating is provided.The utility model is easy to process, with low cost, long service life.
The technical solution of the utility model is: include panel, touch-sensitive panel and circuit board, wherein touch-sensitive panel is close to the lower surface of panel, and touch-sensitive panel is provided with the conductive electrode that is connected with circuit board.
The upper surface silk-screen of above-mentioned panel has the touch key-press symbol, and the touch key-press symbol is corresponding perpendicular to the position of the conductive electrode on the position on the panel direction and the touch-sensitive panel.
The size of above-mentioned touch key-press symbol is also corresponding with the size of conductive electrode.
Above-mentioned touch-sensitive panel cements in the lower surface of panel by adhesive.
The end of above-mentioned conductive electrode is connected on the circuit board by welding or binding post.
Above-mentioned touch-sensitive panel is the flexible PCB plate or is coated with electric conducting material on flexible material.
Above-mentioned flexible material is silver slurry, charcoal slurry, aluminium foil, tinfoil paper.
The utility model is owing to adopt film that flexible material makes as touch-sensitive panel, and design conductive electrode thereon, and employing is close to the panel lower surface to touch-sensitive panel, make conductive electrode and the complete contacting structure of panel lower surface, therefore, the utility model induction sensitivity height, operation control reliability height.The utility model is a touch controlled key device a kind of easy to process, with low cost, convenient and practical.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Embodiment:
Structural representation of the present utility model includes panel 1, touch-sensitive panel 2 and circuit board 3 as shown in Figure 1, and wherein touch-sensitive panel 2 is close to the lower surface of panel 1, and touch-sensitive panel 2 is provided with the conductive electrode 21 that is connected with circuit board 3.
For ease of user operation, the upper surface silk-screen of above-mentioned panel 1 has touch key-press symbol 11, and touch key-press symbol 11 is corresponding perpendicular to the position of the conductive electrode 21 on the position on the panel direction and the touch-sensitive panel 2.In the present embodiment, the size of above-mentioned touch key-press symbol 11 is also corresponding with the size of conductive electrode 21.
In the present embodiment, above-mentioned touch-sensitive panel 2 cements in the lower surface of panel 1 by adhesive.The end of above-mentioned conductive electrode 21 is connected on the circuit board 3 by welding or binding post.
Above-mentioned touch-sensitive panel 2 is for the flexible PCB plate or be coated with electric conducting material on flexible material.Above-mentioned flexible material is silver slurry, charcoal slurry, aluminium foil, tinfoil paper.
The principle of foregoing circuit plate 3 is same as the prior art, includes voltage amplifier circuit, modulate circuit, single-chip microcomputer etc.
The operation principle that the utility model is used for cooking furnace is as follows: when the cooking furnace energising is used, the light finger light touches is to the touch key-press symbol 11 of panel 1 upper surface, the electric capacity that is close to formation between conductive electrode 21 and the finger on the touch-sensitive panel 2 below the panel 1 will make the voltage of the subsequent conditioning circuit on the circuit board 3 change, this changes again through after the amplifying circuit amplification, adjusting by modulate circuit, signal is sent to MCU carry out sampling processing, realization is identified as key information with the touch signal of finger, and then realizes controlling electric equipment products.
The utility model is owing to adopt film that flexible material makes as touch-sensitive panel, and designs conductive electrode thereon, adopts touch-sensitive panel is close to the panel lower surface makes conductive electrode and the complete contacting structure of panel lower surface.Therefore, the utility model induction is sensitive reliable, easy to process, with low cost.
