Abstract
The utility model relates to an automatic power supply switch, wherein the motion of an infrared heat-release inductive probe is controlled by a transmission mechanism, a signal detected by the infrared heat-release inductive probe controls the power of a relay, and the contact of the relay turns of/off the power supply. Provided is a new current failure switch, which solves the problem that the infrared inductive switch can not detect if the people are still in a room, and provides a auto-power-off function when there is no people.
Description
Technical field
The utility model relates to a kind of automatic power supply switch, particularly a kind of active infra-red line traffic control automatic power supply switch.
Background technology
Place such as classroom, office has many office electrical equipment not close the waste that causes the energy owing to personnel leave, and has accident potential such as fire.
Summary of the invention
The utility model be at when indoor nobody the time powered-down automatically, cause the problem of electricity wasting, a kind of active infra-red line traffic control automatic power supply switch has been proposed.
The technical solution of the utility model is: a kind of automatic power supply switch, comprise that infrared heat releases inductive probe, transmission mechanism, relay, infrared heat is released inductive probe and is released the inductive probe motion by the transmission mechanism control infrared heat, infrared heat is released signal control relay that inductive probe detects and is got electricly, and the contact of relay opens or closes power supply.
The beneficial effects of the utility model are: provided a kind of new cut-off switch, solved in the past as indoor people and sat the problem that infra-red sensor switch just can not be found out, automatic circuit break function when providing unmanned simultaneously.
Description of drawings
Fig. 1 is the principle schematic of a kind of automatic power supply switch of the utility model.
Embodiment
The principle schematic of automatic power supply switch as shown in Figure 1, automatic power supply switch comprises that infrared heat releases inductive probe 2, transmission mechanism 1, relay 3, infrared heat is released inductive probe 2 and is released inductive probe 2 left-right rotation by a transmission mechanism 1 control infrared heat, detects surrounding environment and has or not variations in temperature.Because human body has 37 degree body temperature, has temperature difference with environment temperature, when detecting variations in temperature, this automatic power supply switch is thought the indoor people of having, relay 3 the electric work closing of contact, 4 power supplies of power switch conducts power supply; When detecting less than variations in temperature, it is indoor unmanned that this automatic power supply switch is thought, relay is not worked, and mains switch is closed, and cuts off the indoor electric appliance power supply.
Claims (1)
1, a kind of automatic power supply switch, it is characterized in that comprising that infrared heat releases inductive probe, transmission mechanism, relay, infrared heat is released inductive probe and is released the inductive probe motion by the transmission mechanism control infrared heat, infrared heat is released signal control relay that inductive probe detects and is got electricly, and the contact of relay opens or closes power supply.
