Description

Infrared ray multifunction remote-control socket

The utility model relates to a kind of socket, exactly is a kind of infrared ray multifunction remote-control socket.Existing household socket mostly is common socket greatly, does not have distant control function; Though some socket adopts infra-red remote control, can only control single channel, can not multichannel control respectively, purposes is single, and it is not too convenient to use.

The purpose of this utility model is to design a kind of infrared ray multifunction remote-control socket, existing available infra-red remote control is controlled the remote control socket of single socket break-make respectively, the common socket that the remote control of not being with is arranged again, to make things convenient for the user, enlarge the scope of application, adapt to the needs of different capacity electrical equipment, and bigger three-dimensional receiving angle is arranged.

Design of the present utility model is as follows, comprise plug, power line, shell, socket and infrared transmitter, it is characterized in that said socket comprises at least one common socket that directly links to each other with power line and at least one remote control socket by infrared transmitter control break-make, said socket is placed in an end of shell side by side, the other end positioned inside of shell is by the infrared receiver of being made up of infrared ray receiving element and control corresponding unit, the middle part of this end housing has an infrared ray receive window, and window is provided with the scuttle of a projection.

The utility model is provided with two kinds of different sockets on a shell, the needs that can adapt to different capacity electrical equipment, it can make light fixture, electric fan, television set, multiple household electrical appliance such as radio-cassette player are carried out remote control switch, can make does not need remote control or the bigger electrical appliance co-used socket of power yet, because its socket is arranged side by side, the width of shell is bigger, increased coefficient of safety, socket rollover in also can preventing to use, bigger infrared ray receive window, and its scuttle projection, increase remote control and received the elevation angle, the utility model increased the remote control receiving sensitivity when socket keeps flat, so can have bigger three-dimensional receiving angle.As seen, the utlity model has that applied range, the instructions for use that can adapt to different electrical equipment, receiving angle are bigger, safe and convenient to use, good reliability, need not frequently plug, but prolong socket useful life etc. advantage.

The utility model has following accompanying drawing:
