The device of the present invention will be described in detail below in conjunction with specific embodiments.

As shown in Figure 2, we applied the multi-touch switch control device proposed by the present invention to a facial cleanser on the market. In Figure 2 side one is the clean surface of the facial cleanser, and one side is provided with a rubber layer. Used to vibrate to clean the face. The e on side 1 in Figure 2 is a working indicator. The cleansing instrument emits light instructions when it is working. It can also have a built-in buzzer to emit sound warnings; through the improvement of the present invention, in Figure 2

side

2, 4 and 6 One sensing electrode is set on the surface, and the sensing electrodes are located at a, b and c respectively. When the cleansing device is not in use, it is in a static state. When the user needs to use the cleansing device, he only needs to pick up the cleansing device by hand, and the parts of the hand picked up the cleansing device touch a and b respectively. At this time, the cleansing device is triggered; that is, the user is picking up At the same time as the cleansing device, the cleansing device is activated without pressing the switch forcefully. When the user touches point c, the vibration frequency of the cleanser is adjusted. The 5 side d in Figure 2 is the charging socket of the facial cleanser, and the charger is used for charging. According to the user's usual usage habits, the present invention sets touch points (sensing electrodes) with different numbers on the product where the finger is easy to touch, so as to realize the operation of different functions. When the use is over, the user only needs to remove the finger from the corresponding touch point (sensing electrode), and the product automatically stops working. By touching more than 2 touch points (sensing electrodes) at a specific position at the same time at the same time (to avoid misoperation), the product can be turned on. In the power-on state, the touch points (sensing electrodes) at the designated position can be triggered by a single point or multiple points. Realize function mode conversion or power adjustment. Example of cleansing instrument: When the finger presses the "touch point a" and "touch point b" at the same time, when the MCU detects the relevant trigger signal, it will output the power-on control signal according to the software instruction set by the product, and realize the vibration, Or heating, or cooling, vacuum pumping and other functions. In the power-on state, the mode conversion or the adjustment of the power output can be realized by point triggering or constant pressing of "touch point c" or other touch points.

The invention activates the electronic appliance through the touch of the induction electrode, eliminating the tedious steps of manual pressing, realizing the customer first concept of "pick up and use", and greatly improve the user experience; because the induction electrode can be set on the side of the electronic appliance For example, the cleansing device can increase the utilization rate of the clean surface of the cleansing device (the button switch on the original clean surface is gone, and the whole surface is made into a massage clean surface); the use of sensor electrodes avoids the shortcomings of the original button switch’s insufficient waterproof ability , Making the waterproof performance of electronic products better.
