Description

Lens structure applied to doorbell Technical Field The utility model relates to the technical field of lenses, in particular to a lens structure applied to a doorbell. Background The Fresnel human body infrared sensing lens is an indispensable accessory for the display function of intelligent household products such as intelligent doorbell and intelligent camera, and is used for collecting infrared light emitted by external human bodies, and then focusing the infrared light onto the surface of the sensor so that the intelligent household products such as camera and camera can detect the infrared light emitted by the human bodies when the human bodies move, and then start and capture images. At present, when the lens is installed, the lens is generally fixed on the doorbell in a screw or adhesive mode, but when the lens is disassembled and assembled, tools (such as a screw driver or a hot air blower) are needed, and the risks of low operation efficiency and screw slipping exist. To this end we propose a lens structure for use on a doorbell. Disclosure of utility model It is an object of the present utility model to provide a lens arrangement for use on a doorbell, which solves or at least alleviates one or more of the above-mentioned and other problems of the prior art.
