Abstract

The utility model discloses an infrared remote control switch, which substantially comprises a power supply circuit, a switch circuit and an infrared receiving circuit, wherein the switch circuit is connected between the power supply circuit and a domestic appliance, and the infrared receiving circuit is connected with the switch circuit. The infrared receiving circuit comprises an infrared receiver which can receive the signals of an infrared emitter, and the infrared receiver circuit controls the switch circuit to show communication (ON) or open circuit (OFF), which results in the turning on or turning off of the domestic appliance.

Description

Infrared telecontrol switch

The utility model relates to a kind of switch, and especially a kind of infrared telecontrol switch can start household electrical appliance by the infra-red remote control mode.

General household appliances as television set, sound equipment, air conditioner etc., are provided with remote control mostly, and must be by the unlatching of the mode control apparatus of remote control, close, exercises such as setting.

But other small household appliances, as various small electric apparatus such as desk lamp, desk lamp, electric fan, dehumidifier, air filters, because it only has the action of opening or closing usually, and there is no other setting action, so it is comparatively simple in operation, therefore there is no the device of remote control, if the action that then must open or close will operate the time to the position side of placing this electrical equipment, thereby comparatively bother in the use inconvenient.And because the existing mostly remote control of present household appliances makes most consumer be accustomed to the controlling electric device that uses a teleswitch; But the electrical equipment of general simple type does not then have the device of remote control as the electrical equipment that unlatching (ON) is only arranged or cut out (OFF) action, thereby more sense trouble and inconvenience in the use.

Especially in the family if old man or handicapped person are arranged, when they are in alone, then especially feel trouble inconvenience if will operate these small household appliances.

For addressing the above problem, the utility model is designed a kind of infrared telecontrol switch, and its main purpose is to provide a kind of remote control switch that can be started household electrical appliance by the infra-red remote control mode that gets.

Infrared telecontrol switch of the present utility model mainly is made up of power circuit, switching circuit and infrared radiation receiving circuit; Wherein this switching circuit is connected between this power circuit and the household electrical appliance, and this infrared radiation receiving circuit connects switching circuit, this infrared radiation receiving circuit has an infrared receiver again, and this infrared receiver must receive the signal of an infrared transmitter, make this infrared radiation receiving circuit control switch circuit be conducting (ON) or open circuit (OFF), make aforesaid household electrical appliance be opened or close.

After using infrared telecontrol switch of the present utility model, can make the household appliances that do not have remote control originally can remote control open or close, greatly facilitate people especially to old man or handicapped person's life.

Below be accompanying drawing of the present utility model:

Fig. 1 is a circuit block diagram of the present utility model;

Fig. 2 is a circuit diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model is elaborated:

At first, see also Fig. 1 and Fig. 2, the utility model mainly is made up of power circuit 1, switching circuit 2 and infrared radiation receiving circuit 3, and is now that the annexation and the effect division of each circuit is as follows:

Power circuit 1, it connects civil power in order to the supply internal circuit;

Switching circuit 2, it is connected between this power circuit 1 and the household electrical appliance 4;

Infrared radiation receiving circuit 3, it connects switching circuit 2, this infrared radiation receiving circuit 3 has an infrared receiver 31, and this infrared receiver 31 can receive the signal of an infrared transmitter 32, make these infrared radiation receiving circuit 3 control switch circuit 2 be conducting (ON) or open circuit (OFF), make aforesaid household electrical appliance 4 be opened or close.

According to above-mentioned structure, but make infrared receiver 31 receiving infrared-ray signals by infrared transmitter 32 emission signals, two comparators 33 in this infrared radiation receiving circuit 3 can change into high state (HIGH) by low state (LOW), and make switching circuit 2 change into high state by low state equally, so can make power circuit 1 power supply, and make switching circuit 2 be conducting (ON) state, household electrical appliance 4 are opened.

This infrared transmitter 32 is launched signal again one time again, after then this infrared receiver 31 receives signal, two comparators 33 in this infrared radiation receiving circuit 3 can change into low state (LOW) by high state (HIGH), and make switching circuit 2 change into low state by high state equally, so can make power circuit 1 outage, and make switching circuit 2 be (OFF) state that opens circuit, household electrical appliance 4 cut out.

Therefore, if repetitiousness push the unlatching that infrared transmitter 32 can loop control household electrical appliance 4 or close.

Moreover household electrical appliance 4 can connect use, so that use with infrared transmitter 32 remote controls if unlatching (ON) is only arranged or cut out the control action of (OFF).

And owing to be able to infrared transmitter 32 remote control home appliances 4, as desk lamp, desk lamp, electric fan, dehumidifier or air filter etc., thus so that manipulate, especially old man or handicapped person are manipulated.

Claims

1. infrared telecontrol switch, it is characterized in that: it comprises:

In order to the power circuit of supply internal circuit, it connects civil power;

Switching circuit, it is connected between power circuit and the household electrical appliance;

Infrared radiation receiving circuit, it connects switching circuit, and this infrared radiation receiving circuit has a signal that is used to receive an infrared transmitter, makes this infrared radiation receiving circuit control switch circuit be conducting (ON) or opens circuit (OFF) thereby the infrared receiver that makes aforesaid household electrical appliance be opened or close.
