As shown in fig. 4, the signal transmitting module has the following structure and working principle: the three-point LC push-pull oscillator comprises transistors VT1 and VT2, an inductor L1, capacitors C1 and C2 and the like, wherein the resistors R1 and R2 are bias current resistors, the capacitors C1 and C2 and the inductor L1 form a parallel resonant circuit, the parallel resonant circuit is tuned to 28MHz and is used as a common load access circuit of the transistors VT1 and VT2, and the capacitors C3 and C4 are coupling capacitors, so that the oscillator oscillates to generate a 28MHz constant-amplitude high-frequency oscillation signal due to a strong positive feedback effect. When different oscillation currents flow through the inductor L1, high-frequency oscillation signals with different powers are coupled to the inductor L2 due to mutual inductance, and are transmitted to the air by the antenna to serve as command signals, so that the signal receiving module can receive the command signals and perform corresponding actions according to the command signals.
As shown in fig. 5, the signal receiving module has the following structure and working principle: the super-regenerative detector is composed of a transistor VT1, an inductor L1, capacitors C4, C5 and C6, a resistor R2 and the like. The transistor VT1, the inductor L1, the resistors C4 and C5 form a capacitance three-point oscillator, the oscillation frequency is determined by a parallel resonant network consisting of L1 and C4 and the value of a feedback capacitor C5, wherein the feedback intensity can be adjusted by C5. When receiving the command signal sent by the transmitting module, the inductor L1 and the capacitor C4 are in parallel resonance with the resonant tank, and the oscillator starts to oscillate. In the process of oscillation establishment, high-frequency current in the resonant loop inductor L1 and the capacitor C4 charges the capacitor C6 through the capacitor C5 and the interelectrode capacitor of the transistor VT1, the voltage on the capacitor C6 is gradually increased, the voltage is applied to an emission junction of the transistor VT1 as a direction bias voltage, so that the direct-current operating point of the warning inductor VT1 is rapidly moved downwards, and high-frequency oscillation is weakened.
When the voltage on the capacitor C6 rises to make the BE-to-BE voltage of the transistor VT1 less than the turn-on voltage, the transistor VT1 is turned off and the oscillator stops oscillating. Then, the capacitor C6 is discharged through the resistor R2, so that the emitter junction of the transistor VT1 obtains forward bias again, and the next oscillation process is re-established, thereby forming the high-frequency oscillation modulated by the intermittent oscillation formed by charging and discharging the capacitor C6. When the high-frequency instruction signal transmitted by the remote control of the transmitting module is not received, the circuit gain is very high, and external stray interference and thermal disturbance of elements in the circuit are amplified, so that the circuit presents very large 'super noise'. This "super noise" is outputted from the upper end of the resistor R2, and a noise voltage of about 14mV is obtained after high frequency components are filtered out by DZL. And then sent to a two-stage low-frequency amplification stage for amplification, wherein the transistor VT2 and the like form a voltage amplification stage. The resistors R4 and R5 are bias resistors, and the transformer T is a load of the transistor VT 2. The signal output by the secondary of the transformer T is directly coupled to the base of the transistor VT3 for ice-lightning power amplification, which is without base dc bias. The resistor R6 is a load resistor of the transistor VT3, the amplified noise signal voltage of about 2.5V is obtained from the resistor R6, the noise signal voltage is coupled by the capacitor C8, and is subjected to voltage doubling rectification by the diodes VD1 and VD2 and filtering by the capacitor C12 to control the conduction of the transistor VT4 to enable the relay J to attract, signals are input to the MCU control chip, and the MCU control chip instructs the relay with corresponding power, such as K1 or K2, to attract, so that the motor of the intelligent range hood is electrified to work, and the corresponding power work is realized.
When the signal receiving module receives 28MHz constant-amplitude high-frequency command signals with different powers sent by the transmitter, the 'super noise' in the super regenerative detector is suppressed, so that the super regenerative detector has no noise voltage output. At the moment, the transistor VT4 is cut off, the relay J is released, the K1 relay or the K2 relay of the intelligent range hood circuit driving module is powered off, meanwhile, the MCU control chip instructs the relay K4 or the K5 to suck, so that the motor works with corresponding power, and the power of the intelligent range hood can be remotely and synchronously adjusted according to the working power of a cooker.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
