Description

The timing broadcaster

The utility model relates to the time controller of household electrical appliance, and concrete is a kind of timing broadcaster.

Raising along with people's living standard, all there are stereo set and electronic clocks such as radio cassette player, radio in many families, existing stereo set, Source Music, radio cassette player, sound-track engraving apparatus do not have timing function, promptly can not regularly broadcast, and existing electronic clock sound is too small, and dull, the people has been listened feel ear-piercing, nervous sense is arranged, and some alarm clock can only send sharp-pointed alarm song.Existing electronic clock and existing stereo set organically can be combined, making stereo set possess function does not regularly also have such product in the market.

The purpose of this utility model is to realize above-mentioned imagination, electronic clock and stereo set are organically combined, under the prerequisite that does not change electronic clock and stereo set inner structure, make stereo set increase function regularly, and do not influence the original effect of electronic clock and stereo set, they are melted into a whole, make it more perfect, more be subjected to people's welcome.

The purpose of this utility model is achieved in that

A kind of timing broadcaster includes electronic clock, stereo set, it is characterized in that: this electronic clock is connected by a terminal box with single equipment that rings; Be provided with transformer B in the terminal box, by the rectifier bridge that capacitor C 1, C2, diode D1, D2 form, battery E1, direct supply output plug E2, time switch K1, short circuiting switch K2, ac power plug CT; Wherein the former limit winding of transformer B is connected with ac power plug CT; The two ends of the secondary winding of transformer B are connected with two input ends of rectifier bridge respectively; The output terminal of this rectifier bridge is connected with the positive pole of battery E1; The center tap of the secondary winding of transformer B is connected with the negative pole of battery E1; Time switch K1 is in parallel with short circuiting switch K2; Direct supply output plug E2 connects into the closed-loop path through the both positive and negative polarity of short circuiting switch K2 and battery E1; Time switch K1 is connected with timing output plughole on the electronic clock; Direct supply output plug E2 is connected with direct supply input jack on the stereo set.

The utility model has following positive beneficial effect:

The utility model as time controller, is a terminal box by adjunct circuit with the timing function of electronic clock; The power supply of time switch control stereo set such as radio cassette player is realized regularly broadcast, decides the clock circuit chip because of present electronic clock all adopts number; Generally all have warning output terminal and sleep output terminal, the warning output terminal can drive outside load such as the loudspeaker that connects and send chimes of doom, the sleep output terminal can preset regularly, can be used for doing timer, the sleep timing can be used for as time controller, promptly pass through adjunct circuit, interiorly at certain time intervals close load automatically, as the household electrical appliances device, through be set the length of one's sleep, clock will carry out timing by dividing to scale down, when arrive 0:00 the length of one's sleep, the upset of sleep output terminal level makes electrical equipment open or turn-off.The novel terminal box of passing through of this reality makes stereo set increase timing function, and do not influence electronic clock and the original effect of stereo set under the prerequisite that does not change electronic clock and stereo set inner structure, and they are melted into a whole, and makes it more perfect, and is more popular to people.

Now in conjunction with the accompanying drawings the utility model is described in further detail as follows:

Fig. 1 is the embodiment that the utility model is formed structural representation;

Fig. 2 is the synoptic diagram of terminal box among Fig. 1;

Fig. 3 is a kind of circuit theory diagrams of existing electronic clock;

Fig. 4 is another embodiment of the novel composition structural representation of this reality.

See also Fig. 1: timing broadcaster of the present utility model, include electronic clock 1, stereo set 2, it is characterized in that: this electronic clock 1 is connected by a terminal box 3 with stereo set 2; See also Fig. 2: be provided with transformer B in the terminal box 3, by the rectifier bridge that capacitor C 1, C2, diode D1, D2 form, battery E1, direct supply output plug E2, time switch K1, short circuiting switch K2, ac power plug CT; Wherein the former limit winding of transformer B is connected with ac power plug CT; The two ends of the secondary winding of transformer B are connected with two input ends of rectifier bridge respectively; The output terminal of rectifier bridge is connected with the positive pole of battery E1; The center tap of the secondary winding of transformer B is connected with the negative pole of battery E1; Time switch K1 is in parallel with short circuiting switch K2; Direct supply output plug E2 connects into the closed-loop path with the both positive and negative polarity of battery E1 behind short circuiting switch K2; Time switch K1 is connected with timing output plughole on the electronic clock; Direct supply output plug E2 is connected with direct supply input jack on the stereo set.

By above description as can be known, terminal box 3 is equivalent to the power supply that timing function is arranged of stereo set, itself be provided with two cover power supplys in the terminal box 3, a cover is battery E1, and a cover is the power supply that is made of transformer B, ac power plug CT, rectifier bridge, wherein battery E1 can be an accumulator, when electrical network had electricity, whole device passed through attaching plug CT from the electrical network power taking so at ordinary times, and accumulator E1 is charged, during grid power blackout, be the power supply of this device by accumulator E1; K switch 2 is a short circuiting switch, and after K switch 2 closures, time switch K1 is inoperative; Stereo set is not subjected to timing controlled, and behind 2 dozens of passes of K switch, stereo set is subjected to timing controlled, can regularly turn-off.

See also Fig. 3, existing electronic clock comprises three major types: the liquid crystal digital clock, the light emitting diode digital clock, quartzy digital clock, these digital clocks all are made of the integrated circuit of clock chip, this chip functions is powerful, have the I/O interface, can drive load, circuit shown in Figure 3 is present the most frequently used a kind of electronic clock circuit, it is made of digital clock universal integrated circuit chip LM83 61 series or MM5397 series, it is a kind of multiduty 5 functional clocks, can be as standard time clock, the warning clock, timing watch, electronic stopclock, counter etc., its 25 pin is the warning output terminal, is used for external alarm, as loudspeaker etc., its 27 pin is the sleep output terminal, can be regularly as time controller, what the utility model had promptly used digital clock extends out the timing function interface, is inserted in the 27th pin by the K switch among Fig. 21 and obtains timing signal, timing can preestablish by switch S among Fig. 31 to S7, clock will carry out timing by dividing to scale down, when arrive 0:00 the length of one's sleep, and sleep output terminal level generation saltus step, when level skips to low level by high level, stereo set turn-offs, and when level skipped to high level by low level, stereo set was opened.

See also Fig. 4, if the capacity of stereo set inside is enough big, also digital clock and terminal box together can be installed in stereo set inside, like this, timing broadcaster of the present utility model can be seen the time, can regularly broadcast, can not timing broadcast, at any time can playing back music, as long as closed not timing K switch 2, it is little to have solved electronic clock doorbell sound, and dull problem can make people's mood happy simultaneously, get up on time, workman particularly, teacher, student etc. wants the early bird, plays magnificence, and inspiring song effect is best, everyone can feel at ease heart sleep like this, it is punctual to guarantee, in time get up, and be numerous workmans, teachers and students' desirable companion.
