Abstract

The utility model provides a kind of phone controllable screening device, and it is by ring detecting circuit, holding circuit, and playback circuit, timing circuit, code detection circuit, recording circuit, buzzer are through electrically connecting formation.Its advantage is, can stop that not critical phone disturbs the owner who is having a rest or doing important thing, not answer the phone that urgent need is answered, create conditions for owner avoids interference but do not delay owner, this device both can be used as separate piece and had been contained in the telephone circuit, also can be used as accessory and was contained in the phone.

Description

Phone controllable screening device

Technical field: the utility model relates to a kind of Communication Equipment, particularly a kind of phone controllable screening device.

Background technology: in the use of existing telephone, a kind of situation is arranged, existing telephone can't be handled, promptly when a people is in rest or important thing is arranged, do not wish that inessential phone disturbs, but can not lose the important phone of throwing into.People handle this problem otherwise are exactly to have put microphone or dialled phone down, all numbers are not all advanced, otherwise be exactly to answer the important or unessential phone that all are thrown into, and obviously this dual mode is not desired.

Summary of the invention: the purpose of this utility model is to propose a kind ofly both can hinder unessential phone, can tap into the device of important phone again---a kind of phone controllable screening device.

Can realize the purpose of this utility model by following technical proposals, a kind of phone controllable screening device, it is characterized in that, its formation is: ring detecting circuit and holding circuit, playback circuit, timing circuit, code detection circuit electrically connect, playback circuit and recording circuit electrically connect, timing circuit and holding circuit electrically connect, and code detection circuit and buzzer electrically connect.

Effect of the present utility model is that it can stop to fall unessential incoming call for owner, avoids the interference of these incoming calls, makes it can have a rest or attentively do important thing well, does not delay the access of important phone simultaneously again.

Description of drawings:

Accompanying drawing 1 is a circuit block diagram of the present utility model.

Embodiment: referring to accompanying drawing, ring detecting circuit 1 electrically connects with holding circuit 2, playback circuit 3, timing circuit 4, code detection circuit 5.Playback circuit 3 electrically connects with recording circuit 6.Timing circuit 4 electrically connects with holding circuit 2.Code detection circuit 5 electrically connects with buzzer 7.State display switch 8 is connected in the circuit.

The workflow of this device is: open switch 8, enter state on duty, when phone was squeezed into, ring detecting circuit 1 detected bell signal, started holding circuit 2 immediately and made the telephone set can not ring, started playback circuit 3, code detection circuit 5 and timing circuit 4 simultaneously.Playback circuit 3 is to calling party message, and message can be: " owner has a rest, if no urgent thing please beats after a while, be in a hurry please continue group code * * * or password ".At this moment, there is following several situation to take place, 1, the calling party do not have urgent thing, on-hook immediately, timing circuit then discharges holding circuit, and this device is got back to state of value.2, the calling party is in a hurry, continuous dial code * * * or password, detect through code detection circuit 5, as correctly, buzzer rings, the called machine of getting, holding circuit 2 discharges, this device is got back to state on duty; If the called machine of not getting, timing circuit 4 then discharges holding circuit 2, and this device is got back to state on duty.3, caller continuous dial code * * * or password bad, timing circuit 4 then discharges holding circuit 2, this device is got back to state on duty.

This device both can be made a separate piece, was positioned on the telephone line, also can be used as an accessory and was contained in the telephone set.

Claims

1, a kind of phone controllable screening device, it is characterized in that, its formation is: ring detecting circuit and holding circuit, playback circuit, timing circuit, code detection circuit electrically connect, playback circuit and recording circuit electrically connect, timing circuit and holding circuit electrically connect, and code detection circuit and buzzer electrically connect.
