Background
In many electronic devices, especially household appliances, knob switches are often used for parameter setting and operation. The knob switch of physical connection, such as potentiometre formula knob switch, area pole coding formula knob switch, in use can influence life because of mechanical structure's wearing and tearing, and the knob switch of physical connection is owing to need trompil on electrical equipment's panel when using, destroys the integrality and the leakproofness of equipment shell, leads to the atress intensity of panel to weaken greatly, still can lead to the outside pollutant of equipment to get into inside the equipment, constitutes pollution and destruction to the inside spare part of equipment and circuit, has hindered the cleanness of panel to a certain extent simultaneously. Therefore, in recent years, a non-contact sensing knob switch is increasingly used, in which a non-contact sensing knob is composed of two parts, i.e., a non-contact sensing knob and a knob sensing circuit, the non-contact sensing knob is disposed at a fixed position on the outer surface of an operation panel, and knob sensing electricity is provided inside the operation panel, the non-contact sensing knob is not in contact with the knob sensing circuit, and the non-contact sensing knob can be moved or removed at will. The non-contact sensing knob brings great technological sense and simple operation to products using the knob switch. However, the non-contact sensing knob is not fixed, so that certain potential safety hazard exists in the operation under the condition of removal. Like children at home, feel curious and remove non-contact response knob to non-contact response knob, and removed the in-process and carelessly triggered the cooking utensils to fire, because the unknown of family after the cooking utensils are fired, the cooking utensils can have the hidden danger of conflagration to endanger user's safety for a long time burning.
Of course, some of the considered products may add a child lock button on the device using the non-contact sensing knob switch, so that the child lock is locked when the device is used up, and the child lock is unlocked when the device is used. Although the mode can solve the potential safety hazard to a great extent, the cost is increased, and more use steps are brought to users, so that the usability of the equipment is reduced.
