Description

Inferior ripple Electronic Remote Switching

The utility model relates to a kind of teleswitch of household electrical appliance.

Existing teleswitch includes remote control transmitter and receiver, and receiver is to improve on original wiring board mostly, or changes, or overlapping linking to each other, and uses inconvenience, and charged all the time, wastes energy.

The purpose of this utility model provides a kind of inferior ripple electronic romote-controller, and this telepilot volume is little, easy to use, and not charged during electrical appliance, saves energy.

The purpose of this utility model is achieved in that it partly is made of inferior ripple electronic emitter and Ya Bo electronic receiver two, transmitter is an air bag, receiver is a square type or round socket, there is plug the socket bottom surface, or directly insert the wiring board input end and become many electric appliance remote controllers, the socket capping have two holes or (with) three hole jacks, and have luminous pore and a signal receive window, one circuit board is installed in the socket, circuit board is provided with electric power loop, signal receives and LC frequency-selective circuit, bistable trigger-action circuit and relay switching circuit.

Fig. 1, Fig. 2 have provided outside drawing of the present utility model;

Fig. 3 is acceptor circuit figure;

Fig. 4 is emitter structures figure.

As shown in Figure 1 and Figure 2, the utility model is to be made of inferior ripple electronic emitter 6 and 1 liang of part of Ya Bo electronic receiver, transmitter 6 is an air bag, receiver 1 is a square type or round socket, there is plug the socket bottom surface, or directly insert wiring board input end 2 and become many electric appliance remote controllers, the socket capping have two holes or (with) three hole jacks 5, and have luminous pore 3 and a signal receive window 4, one circuit board is installed in the socket, circuit board is provided with electric power loop, signal receives and LC frequency-selective circuit, bistable trigger-action circuit and relay switching circuit.As shown in Figure 3, C among the figure ₁Be decompression capacitor, establish this electric capacity purpose and be for AC network anti-interference.D ₁-D ₄, C ₂Deng the composition electric power loop.C ₃Be coupling capacitor, HT is that acoustic pressure sheet signal receives inverting element, L, C ₄Form frequency-selective circuit, D ₅Be slicing, V ₃, V ₄With D ₆, D ₇, C ₇, C ₈, R ₆, R ₈, R ₉, R ₁₁Form bistable circuit, V ₅Export anti-phasely, K is that topworks drives load, D ₈Be the K discharge loop.Its principle of work is as follows:

220 volts of alternating currents are through C ₁Step-down gets the 12V DC voltage behind diode rectification.After piezoelectric patches was received signal when the signal input was arranged, through V ₁Amplify, the frequency-selective circuit select-out signal of being made up of L, C is again through D ₅Amplitude limit V ₂Amplify and remove to trigger bistable circuit, make its circuit upset, relay is a topworks, and relay adhesive (operating current 9 μ A) back drives and exchanges (220V) load.When input signal once more, bistable circuit overturns again, and circuit is got back to the incipient stage.Relay quits work when no signal.

Inferior ripple telepilot transmitter is an air bag.See Fig. 4, when quick-moving speed is pinched air bag, produce certain pressure, sound wave is penetrated in acceleration when making the interior air flow stream of balloon cross siren, the radiative acoustic wave frequency is 18KHz.Receive transducing electron device TH and select piezoelectric ceramic piece for use, piezoelectric ceramic piece is a dome-type, and sphere is positioned at the window 4 of socket capping.

More than be not difficult to find out, the utlity model has following 2 outstanding effects:

1, this receiver can directly insert in the former socket, or receiver is inserted the input end of wiring board, becomes many electric appliance remote controllers, also need not change the structure of former socket, and is very convenient, practical during use.

2, owing to adopt bistable circuit and relay topworks, electricity is arranged just when load (making electrical appliance) is arranged, not the time spent not charged, save the energy, safe in utilization, economical.

Claims (2)
