Problems solved by technology

[0003] In order to solve the problem that the existing switch cannot control the fresh air volume and air quality at the same time, the present invention provides a cycle timing intelligent electronic switch, which is used to control the ventilation equipment, so that the indoor air pollution is always kept at a low level, and on this premise The most energy-saving; the switch can retain the original "circulation timing pressure regulating switch" stepless speed regulation function, and can also be changed to multi-speed regulation, so as to match the ventilation equipment with multi-speed regulation

Embodiment Construction

[0021] exist figure 1 In the schematic circuit diagram shown, the input end of the step-down rectification and voltage stabilization circuit (1) is connected to the mains, and the output end is respectively connected to the cycle timing circuit (2) and the intelligent sensing module (3), and the cycle timing circuit (2) It is connected in parallel with the intelligent sensing module (3), and the output signal is merged and connected with the trigger pole of the electronic switch (4), thus forming a complete cycle timing intelligent electronic switch circuit.

[0022] In the step-down rectification and voltage stabilization circuit (1), the resistor R 1 , Capacitor C 2 、C 4 , rectifier diode VD 3 , Zener diode VD 4 A low-voltage DC power supply is provided for use by the cycle timing circuit (2). The cycle timing circuit (2) takes the time base integrated NE555 as the core, when the power is just turned on, due to C 5 There is no time to charge, the ② pin of the time base...

Abstract

The invention relates to an electric switch, particularly to a cycle-timing switch with adjustable speed for controlling power source on and off according to quality of indoor air. The invention can be applied to controlling indoor ventilation device, so as to guarantee that indoor fresh wind quantity meets the lowest standard for indoor staff, and that concentration of indoor air pollutant maintains at lower level below qualified concentration, and energy can be saved in maximum based on these two conditions. The invention also can meet speed regulation control of change speed and stepless speed regulating ventilation device.

Description

Technical field [0001] The invention relates to an electronic switch, especially a switch capable of cycle timing, speed regulation, and control of power on and off according to indoor air quality. Background technique [0002] "Cycle timing pressure regulating switch" (patent number: ZL 2004 2 0095710.9, applied by myself on November 26, 2004) solves the energy-saving and noise problems of civil exhaust fans. Due to the fact that indoor environmental pollution is relatively common at present, the circulation and timing exhaust can meet the fresh air volume requirements of indoor personnel, but the indoor air quality may not be up to standard; in addition, fresh air systems have begun to enter Chinese homes, and these fresh air systems from European and American countries require 24 hours without Stopping the ventilation will easily cause empty energy consumption, and it does not match our living habits. The "circulation timing pressure regulating switch" can make the fresh ...
