2results about How to "Improve touch reliability" patented technology

The utility model relates to a light adjusting circuit technical field discloses a kind of LED lamp strip control circuit with touch and PWM light adjustment with simple structure, touch sensitivity is high and stable light adjustment effect, including touch area circuit (100), touch detection circuit (110), MCU main control circuit (120), LED drive circuit (130) and MOS tube power supply on-off circuit (140), wherein, when the control signal of MCU main control circuit (120) input is high level, MOS tube power supply on-off circuit (140) is controlled to be conducted, to control MOS tube power supply on-off circuit (140) to LED drive circuit (130) output a voltage signal, the duty cycle of LED drive circuit (130) regulation output PWM signal, to control the voltage of LED drive circuit (130) loading in LED lamp strip.

This application relates to the field of household appliance technology, specifically providing a housing and a household appliance, aiming to solve the problems of decreased touch sensitivity of touch buttons due to environmental interference and mechanical jamming of mechanical buttons in existing household appliances. To this end, the housing of this application includes: a base body with a mounting cavity; a switch assembly disposed within the mounting cavity, the switch assembly including a circuit board and a trigger part connected to the circuit board; and a protective sleeve having a connecting end and a pressing end opposite to the connecting end, the connecting end being located within the mounting cavity and connected to the trigger part, and the pressing end being at least partially exposed outside the mounting cavity. In this application, the housing isolates dust, liquids, and other contaminants through the physical barrier of the pressing end of the protective sleeve, preventing trigger signal interference and short circuits, improving touch reliability, and enhancing user experience. Simultaneously, the connecting end of the protective sleeve directly engages or snaps with the trigger rod, simplifying the mechanical structure and helping to eliminate the risks of mechanical wear and foreign object jamming.
