Abstract

The utility model provides a timing turn off socket for the electric appliance power socket field. The utility model is mainly characterized in that: a timing turn off circuit is arranged inside a shell and connected with a commercial electricity inlet wire of a power socket, and comprises a relay turn off switch, a changeover separate circuit, a signal processing separate circuit and a timing watch which are connected with each other. Compared with the prior power socket, the utility model has the advantages of capability of automatically turning off the power in definite time, convenience brought about to people, avoidance of damage and accidents caused by human negligence when some electric appliances are operated overtime, simple structure, reliable work, low operational electricity consumption, no electricity consumption under the condition that the socket is not used, etc.

Description

Regularly turn-off socket

Technical field

The utility model belongs to appliance field, relates to supply socket, is specifically related to a kind of timing and turn-offs socket.

Background technology

Existing supply socket comprises shell, the mains supply inlet wire, and jack, by artificial insertion or extract the attaching plug of electrical appliance, or by artificial open-close on-off.Because need artificial power cutoff in time after many electrical appliance work a period of times, as the charging of battery storage battery, or electric kettle is heated up water, otherwise, often forget not power cutoff in time, electrical appliance workpiece overlong time because of party's carelessness, gently then cause electrical appliance to damage, heavy then security incident takes place.

The utility model content

The designer in daily life, find that above-mentioned drawback in use appears in existing supply socket easily, exist can not timing to automatically switch off power supply defective, purpose is to provide a kind of timing to turn-off socket, can overcome the existing problem of existing power supply socket preferably.

Technical solution adopted in the utility model is that socket is turn-offed in a kind of timing of design, and its structure comprises: supply socket also is connected with the civil power inlet wire of supply socket in the enclosure the timing breaking circuit is set.

Described timing breaking circuit adopts by the relay stopcock, the conversion parallel circuit, the signal processing parallel circuit, timing indicator constitutes, the switch of relay stopcock is connected in the civil power inlet wire of supply socket, its relay is connected with the output of signal processing parallel circuit, the dropping resistor inlet wire of conversion parallel circuit is connected with the switch outlet of relay stopcock, the power input of signal processing parallel circuit is connected with the output of conversion parallel circuit, and the output of timing indicator is connected with the signal input part of signal processing parallel circuit.

The K switch of manually opened relay stopcock, to the power supply of this machine, the work of this machine, the conversion parallel circuit through step-down, rectification, filtering, voltage stabilizing, is transformed into low-voltage DC to civil power, supplies with signal processing parallel circuit and relay J.After the attaching plug of electrical appliance inserts socket, electrical appliance work operation.When the time of operation reaches the time that timing indicator sets, the output signal of telecommunication of timing indicator is anti-interference through the signal processing parallel circuit, after the processing and amplifying, deliver to relay J control switch K and turn-off, thus automatically cutting off power source, stop the power supply to supply socket and this machine, electrical appliance is out of service automatically.

In case of necessity, also can utilize the switch of relay stopcock, adopt the manual mode power cutoff in advance.

Socket is turn-offed in this timing of the present utility model, compares with existing supply socket, can timing to automatically switch off power supply, bring convenience to the user, and avoid causing the accident because of the out-of-date operation of human negligence electrical appliance; The circuit that adopts is simple and easy to make, and cost is low, reliable operation; Have shutdown during work and do not have only seldom electricity of electric capacity charging consumption during the signal, have only behind the signal of coming moment just power consumption supply with the actuating of relay, not power consumption when not working has obvious advantage.
