Description
Technical field
The present invention relates to small-sized electric generating apparatus, particularly a kind ofly collect the device that body energy is converted into electric energy.
Background technology
From human body, harvest energy has had very long history, but due to the energy that can collect little, cannot effectively be applied.In recent years, the appearance of low power consumption electronic device makes human body produce power become possibility for these equipment are used.The energy-producing form of human body is varied, as swing arm, and walking, the energy that knee kinematics and body temperature etc. behavior or physiology produce.
Breathing is the body energy that another kind may be used for energy regenerating.By human exhaled breath and air-breathing, air completes the process flowing into and flow out.The energy of flow of air produces certain pressure value, and maximum reaches 2% of air pressure, and this is equivalent to the energy of 1W.The major advantage of breathing gas flowing successively to produce, even if people also will constantly breathe in sleep, moreover respiratory rate is substantially constant under human normal activity.Chinese scholars once attempted using human body respiratory to be used as the kinetic energy of energy regenerating, and ChengliangSun in 2011 utilizes micro stripline PVDF successfully to catch breathing can produce voltage, is nW-μ W; Within 2012, AidinDelnavazandJ é r é mieVoix adopts the raw electric principle of electromagnetism, and also can obtain output voltage is several μ W.As previously mentioned, these methods all can only produce lower output voltage and conversion efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of energy collecting device utilizing piezoelectric to collect human body respiration energy and carrying out to generate electricity.
A kind of human body respiration energy collecting device of the present invention, is characterized in that comprising respiratory air flow Power Component and piezoelectricity mouth organ chamber assembly, wherein:
Respiratory air flow Power Component comprises for mouth mask, interface and siphunculus, and interface to be arranged on mouth mask and to be positioned at human nasal upper/lower positions, and interface connects piezoelectricity mouth organ chamber assembly by siphunculus;
Piezoelectricity mouth organ chamber assembly comprises oscillator stationary pipes and piezoelectric vibrator, oscillator stationary pipes end is respiratory air flow gateway, opening is provided with in oscillator stationary pipes stage casing, this opening installs piezoelectric vibrator in the axial direction, and piezoelectric vibrator one end is fixed in oscillator stationary pipes, the other end is unsettled formation cantilever beam structure freely.
The structure species of piezoelectric vibrator is a lot, and being preferably the combination of piezoelectric ceramic and reed, is be pasted on reed side by piezoelectric ceramic by conducting resinl to form piezoelectric vibrator.
Further, in oscillator stationary pipes, control damper is set near respiratory air flow gateway place.
The quantity of piezoelectric vibrator can be one also can be multiple, and when for time multiple, the opening in oscillator stationary pipes stage casing has several, and array distribution is in oscillator stationary pipes, and each opening is provided with a piezoelectric vibrator.
Compared with prior art, its remarkable advantage is in the present invention: human body respiratory rate in normal activity situation keeps constant substantially, in conjunction with mouth organ cavity body structure, and can according to the resonance frequency of respiratory rate determination reed; Add and use the cantilever beam structure of piezoelectric vibrator, can ensure that piezoelectric ceramic vibrates under resonance frequency very well, produce most strong deformation, thus inspire maximum piezoelectricity energy.This structure additionally uses draught damper, can coutroi velocity very well, thus is easy to realize controlling reed amplitude.
