Embodiment 1

[0021] Example 1: See attached figure 1 , the touch switch circuit with a controllable delay time delay provided in this embodiment is composed of a normally closed relay drive circuit S, an adjustable resistor R1, 2 sampling resistors R1, R3, and 2 single MCR100-8 models. It consists of thyristor SCR1, SCR2, electrolytic capacitor C, switch tube mosfet, two touch pieces ON, OFF, load P, and DC power supply VCC-GND; the ground terminal of load P is connected to the location GND of DC power supply VCC-GND; One end of the capacitor C is correctly connected to the ground GND of the DC power supply VCC-GND.

[0022] One of the one-way thyristor SCR1 is used as an opening switch, and the cathode of the one-way thyristor SCR1 as an opening switch is connected to the non-ground terminal of the load P, and the control terminal of the one-way thyristor SCR1 as an opening switch is connected to a touch The slice ON is connected, and the switch K of the normally closed relay drive circu...

Embodiment 2

[0028] Implementation example 2. On the basis of implementation example 1, the load P is set as a relay drive circuit to realize the control of high-power circuits.

[0029] The invention can be directly applied to the manufacture of intelligent lamp control circuits.

[0030] The delay-off touch switch circuit with controllable delay length provided by the present invention has a reasonable design, can delay close, and the delay time is adjustable, and has convenient signal collection (sampling) points and control (adjustment) points, which is convenient It can be directly used in conjunction with an intelligent control program, or directly as a part of an intelligent control circuit, and can be widely used in the manufacture of intelligent home appliances such as lighting, air conditioners, and televisions.

Abstract

The invention provides a touch switching circuit capable of being switched off in a delayed manner and with controllable delay time. The touch switching circuit is characterized by comprising a normally closed relay drive circuit (S), an adjustable resistor (R1), two sampling resistors (R1 and R2), two MCR 100-8 one-way thyristors (SCR1 and SCR2), a capacitor (C), a switch tube (mosfet), two touch pieces (ON and OFF), a load (P) and a direct-current power supply (VCC-GND). The touch switching circuit is reasonable in circuit design, can be switched off in a delayed manner, is adjustable in delay time, and convenient in signal acquisition and control points, can be directly used with an intelligent control program conveniently or directly serve as a part of an intelligent control circuit, and can be widely applied to production of intelligent household appliances such as intelligent lighting equipment, air-conditioners and televisions.

Description

technical field [0001] The invention relates to an electronic circuit technology, in particular to a touch switch circuit with a controllable delay time and a delay close that can be used in conjunction with an intelligent control program. Background technique [0002] Existing household appliances such as touch lamps usually turn off directly after receiving a touch signal to turn off, and in most cases, people need to perform some short-term activities within a short period of time after turning off the lights, such as Need to go to bed etc. in the dark; When people are watching TV programs, if the screen is shut off immediately when the power is cut off when watching TV programs, it will have a large change in people's vision and affect people's vision. [0003] The inventor found materials such as "Simple touch-off circuit diagram composed of one-way thyristor" in Baidu's "Baidu library", but it does not have a delay off function, so the inventor of the present invention...
