Energy-saving device capable of automatically recognizing whether or not people exist in elevator and turning on illuminating lamp

Abstract

The invention relates to the technical field of electricity saving, and discloses an energy-saving device capable of automatically recognizing whether or not people exist in an elevator and turning on an illuminating lamp. The energy-saving device comprises a shell, the elevator is movably connected in the shell, the left end of the elevator is movably connected to an extension spring, the lower end of the elevator is fixedly connected to a supporting rod, the lower end of the supporting rod is movably connected to a connecting rod, the lower end of the connecting rod is movably connected to a guide column, and the left end of the guide column is fixedly connected to a guide block. When the guide block moves leftwards, a leftward pushing force is applied to the guide block, so that the interior is compressed, elastic potential energy is gathered in the guide block, preparation is made for resetting of the guide block, meanwhile, when the guide block moves leftwards, a leftward pushing force is applied to the contact, so that the contact is pushed to move leftwards to make contact with a trigger mechanism, and an internal circuit is connected, therefore, the effects that only when people exist in the elevator, the internal lamp is lightened, and when nobody exists, the internal bulb is turned off are achieved.

Description

technical field [0001] The invention relates to the technical field of power saving, in particular to an energy saving device for automatically identifying whether there is a person inside an elevator and turning on a lighting lamp. Background technique [0002] With the gradual development of society, people's living standards have been significantly improved. With the use of electricity by modern people, a large amount of current is consumed. Therefore, modern people are looking for new energy sources, or research and development of electricity consumption. Products are thus constrained internally, so there are a lot of power-saving machines on the market. [0003] But at present, there are still defects that need to be overcome in the energy saving inside the elevator. The interior of the elevator is opaque, so it needs to be turned on for a long time. At the same time, there are many people and bacteria inside. If the ventilation is not timely, it is easy to infect othe...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an energy-saving device that automatically recognizes whether there are people inside the elevator and turns on the lighting lamps. When there is no one inside, it can purify the internal air and prevent bacterial infection. It solves the problem that the interior of the elevator is opaque and needs to be turned on for a long time. However, when no one is in use, it is a waste of power and consumes a lot of power. , which is not conducive to energy-saving standards. At the same time, there are many people and bacteria inside. If the ventilation is not timely, it is easy to cause other people to be infected.
