Description
Technical field
The utility model relates to a kind of self power generation counter, specifically relates to the novel self power generation counter of a kind of PVDF of employing piezo technology and electrode evaporation metal level technology.
Background technology
Present counter all is to adopt button cell or dry cell power supply mostly, has caused a large amount of old and useless batterys to the pollution of environment; The part counter is with the solar electrical energy generation module, but generating efficiency is very low, and counter must be placed under the illumination could work, at night normally electric power storage, easily outage appears in the low situation of electric weight and numeral shows unsharp situation, the irradiation of sunshine also causes the aging of computer case easily, and greatly reduce serviceable life.
Because we need to press each button in the process of using counter, produced very frequently discontinuity pressure energy, we can convert this part pressure energy to power storage fully and continue for it in the counter, however the equal unrealized this point of traditional counter.
Summary of the invention
The purpose of this utility model is in order to overcome deficiency of the prior art, the self power generation counter that provides a kind of PVDF of utilization piezo technology to generate electricity.
In order to solve the problems of the technologies described above, the utility model is to be achieved through the following technical solutions:
A kind of self power generation counter, it is characterized in that: comprise housing, button, PVDF piezoelectric membrane, electronics contact, evaporation metal electrode, tank circuit plate, button storage cell, a described PVDF piezoelectric membrane minute multilayer is installed on the electronics contact, button is directly over the electronics contact, the evaporation metal electrode is connected with the PVDF piezoelectric membrane, utilize electrode evaporation metal level technology extraction electrode wire, the tank circuit plate is connected on the described electrode cable, and described button storage cell is connected with the tank circuit plate.
Rectification circuit on the described tank circuit plate can be three-phase, single-phase or heterogeneous controlled rectification circuit.
Compared with prior art, the beneficial effects of the utility model are:
When using counter, press the pressure energy of generation at every turn, utilize the PVDF piezo technology to be translated into the electric energy sustainable utilization.It is not lasting to have improved the use of traditional calculations device, and the shortcoming of the refuse battery contaminated environment that produces, and compares with the solar electrical energy generation counter, has greatly improved generating efficiency and the serviceable life of counter, has obvious advantage.
