Longxin Zhongke has obtained a special anti-station circuit and intelligent locking patent for touching keys to improve the effect of filtering the voltage of the amplifier module.

Finance Industry reported on February 28, 2025 that the information of the National Knowledge and Rights Bureau showed that Longxin Zhongke (Jinhua) Technology Co., Ltd. obtained a patent titled \”Anti-touch key identification anti-fixing circuit and smart lock\”. Authorization announcement CN 222531673 U, and the application date is May 2024.

A patent summary shows that this new practical embodiment provides a touch key identification anti-sink circuit and smart lock, involving the field of smart lock technology, including a stable module, a first resistor, a first capacitor module, and a power amplifier. The module and the touch key identify the module, wherein the first resistor and the first capacitor module are combined into a resistor capacitance filter to filter the power amplifier module to remove the signal of the stable pressure module, and then filter the voltage caused by the touch key identification module, and eliminate the voltage severity caused by the touch key identification module. In addition to the misidentification of the touch key identification module on the touch key touch event, due to the splitting effect of the first resistor on the sturbation voltage of the amplifier module, the voltage tampering of the amplifier module on the stable pressure module can be reduced, so the resistor can be resisted. Compared with the capacitor filter in the advanced technology, the capacitive filter improves the effect of filtering the voltage storing signal of the amplifier module, and solves the problem of the misidentification of the touching event of the touching key in the previous technology.
