Cell-less type piezoelectric power generation wireless doorbell

Abstract

The invention discloses a cell-less type piezoelectric power generation wireless doorbell. The cell-less type piezoelectric power generation wireless doorbell comprises a wireless signal outdoor transmitter and a wireless signal indoor receiver, wherein the wireless signal outdoor transmitter comprises a piezoelectric material power generation portion, an electric energy processing portion, a wireless signal transmitting portion, a wireless signal outdoor transmitter casing and a doorbell pressing rod, and the wireless signal indoor receiver comprises a wireless signal reception portion and a power supply. When the doorbell pressuring rod is pressed, pressing force is transmitted through a spring to a piezoelectric material, mechanical energy is converted into electric energy through utilizing the piezoelectric effect, the electric energy is transmitted through the electric energy processing portion to drive the wireless signal transmitting portion to transmit a wireless signal, the wireless signal is received by a wireless signal reception end to generate a ring tone, and the purpose of calling a host is realized. Compared with an electronic doorbell in the prior art, the cell-less type piezoelectric power generation wireless doorbell is advantaged in that the wireless signal outdoor transmitter requires no extra power supply, using dry cells or button lithium cells can be avoided, and the effects of energy saving and environmental protection are realized.

Description

technical field [0001] The invention relates to a wireless electronic doorbell, in particular to a wireless environment-friendly electronic doorbell using piezoelectric material to generate electricity as an energy source. Background technique [0002] Currently, most wireless doorbells on the market require chemical batteries or external power sources. Existing traditional doorbells have some disadvantages. For example, the doorbell device needs batteries (dry batteries or storage batteries) or commercial power to drive and trigger the wireless signal transmitter. Also can cause environmental pollution; Adopt mains power supply to also consume electric energy, have increased carbon discharge, as in case power failure, then doorbell will not work. At present, Qingdao Ao Gena Electronic Technology Co., Ltd. (patent publication number: CN201420078436.8) and Wuhan Lingpu Technology Co., Ltd. (patent publication number: CN201420589205.3) have launched self-generating wireless d...
