Environment-friendly energy-saving doorbell with autonomous power supply function

Abstract

The invention relates to an environment-friendly energy-saving doorbell with an autonomous power supply function. The environment-friendly energy-saving doorbell comprises a barrier layer of a doorbell frame box, guide grooves, a guide ridge, a push rod gear, a guide hammer, a bearing with an outer ring in the shape of a circular truncated cone, a bearing gear, a fixed shaft of a power generation assembly, a base, a convex push rod, a key sleeve, a spring, an annular base plate, a key clamp sleeve, a bolt, a fixing plate, an annular barrier, the doorbell frame box, a spherical contact switch, an oscillating circuit and the like, and is characterized in that the bearing with the outer ring in the shape of the circular truncated cone is arranged at the lower end of the power generation assembly, the bearing gear is arranged on a slope surface of the outer side of the bearing, the guide grooves are oppositely symmetrically formed in the lower surface of the barrier layer of the doorbell frame box and the bottom surface of the doorbell frame box, the guide ridge is arranged between the guide grooves, the guide hammer is arranged between the upper and lower guide grooves and is positioned at one end of the push rod gear, the convex push rod is arranged at the other end of the push rod gear, the push rod gear can be coupled with the bearing gear in pushed procedures, accordingly, the power generation assembly can be driven to generate power, the spherical contact switch can be turned on when the spherical contact switch which is positioned on the inner rear wall of the doorbell frame box is butted to the guide hammer, and the circuit can be closed and starts to oscillate and produce sound.

Description

technical field [0001] The invention relates to an environmentally friendly and energy-saving doorbell with independent power supply, which belongs to the field of household gadgets. Background technique [0002] At present, the power supply of household doorbells all use dry batteries, because the terminal voltage of dry batteries gradually decreases with the prolongation of use time, which affects the normal operation of doorbells and also brings pollution to the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is: Based on the invention of "an energy-saving and environment-friendly mechanical battery" with the patent application number of 201410170566.9, a self-powered, environment-friendly and energy-saving doorbell is provided. When the button of the doorbell is pressed, the push rod gear and the bearing The gear, which enables the generator to generate electricity to power the doorbell circuit. [0004] The ...
