Problems solved by technology
[0002] Nowadays, most of the buttons used in electrical appliances are mechanical buttons. Because there is a gap between the control panel and the buttons of the mechanical buttons, it is easy to cause dirt or oil to accumulate, and it is not easy to clean
At present, some touch buttons have appeared, but in the actual use process, the touch buttons are not effective and prone to insensitivity to touch. Therefore, they are rarely used in real life; and many panels cannot use metal panels. In many environments, the buttons are prone to malfunction, which affects the use

The invention discloses a touch button device, comprising a metal board, a plastic board, a PCB and a control circuit, wherein the metal board, the plastic board and the PCB are sequentially arranged; the upper surface of the metal board is plane; the plastic board is provided with a plurality of through holes; a plurality of sensors are arranged on the PCB; the sensors are arranged corresponding to the through holes; and the plurality of sensors are electrically connected with the control circuit. Therefore, dirt and the like are prevented from depositing, so that the touch button device is convenient to clean and can be widely applied to various electric appliances; the plastic board is provided with the plurality of through holes, so that when people touch the metal board and external force acts on the through holes, the metal board has tiny deformation, and distance between the metal board and the PCB is reduced; when sensors detect that deformation changes, signals are transmitted to the control circuit, so that inductance in the control circuit changes; whether the button is pressed is recognized by the control circuit, and thereby function corresponding to the button is achieved, thus being convenient to use.
Description
technical field [0001] The invention belongs to the field of electrical appliances, in particular to a touch key device. Background technique [0002] Nowadays, most of the buttons used in electrical appliances are mechanical buttons. Because there is a gap between the control panel and the buttons of the mechanical buttons, it is easy to cause dirt or oil to accumulate, and it is not easy to clean. At present, some touch buttons have appeared, but in the actual use process, the touch buttons are not effective and prone to insensitivity to touch. Therefore, they are rarely used in real life; and many panels cannot use metal panels. In many environments, the buttons are prone to malfunction, which affects the use. Contents of the invention [0003] The object of the present invention is to provide a touch key device that can solve at least one of the above problems. [0004] According to one aspect of the present invention, a touch key device is provided, including a meta...
