Description
Technical field
Doorbell, more particularly to a kind of energy-conservation doorbell of the piezo-electric effect of utilization piezoelectric are saved the present invention relates to one kind.
Background technology
Present door bell for anti-theft door is to use battery or directly using the electronic door bell of electricity mostly, because of the terminal voltage of dry cell,
Extend with use time and be gradually reduced, and influence doorbell normal work, while can also cause environment pollution.It is estimated, mesh
The battery level of preceding doorbell is about 7.896 hundred million sections.It is apparent that the battery level of doorbell is one and opened greatly very much according to analysis
Branch, while the harm to environment is also larger.And electronic door bell has the problem of energy expenditure is with frequently battery is changed, with society
Meeting expanding economy, various pollutions and energy consumption are CR Critical, and energy-saving and emission-reduction have become the main flow of the world today.
Piezoelectric is a kind of can to realize the functional material that mechanical energy and electric energy are mutually changed.Piezoelectric is being pressed
Voltage can occur between both ends of the surface in the masterpiece used time, and this is based on caused by piezo-electric effect.Piezo-electric effect refers to that some dielectrics exist
Polarization phenomena can be produced when being deformed in a certain direction by the effect of external force, inside it, while in its two with respect to table
Occurs positive and negative opposite electric charge on face.After external force is removed, it can return to uncharged state again.Piezoelectric is divided into organic
Piezoelectric and inorganic piezoelectric material.Wherein, inorganic piezoelectric material is divided into piezo-electric crystal and piezoelectric ceramics, and piezo-electric crystal is usually
Refer to piezoelectric single crystal；Piezoelectric ceramics then refers to piezoelectricity polycrystal.Piezoelectric ceramics refers to be mixed with the raw material of necessary composition, into
Type, high temperature sintering, solid phase reaction and sintering process between powder and the fine-grain irregular collective that obtains it is many
Crystal.Organic piezoelectric materials are also known as piezopolymer, and such as Kynoar (PVDF) (film) and other using it as representative have
Machine piezoelectricity (film) material.The application field of present piezoelectric can be roughly classified into two major classes:That is vibrational energy and ultrasonic vibration
Energy-electric energy transducer application, including electroacoustic transducer, underwater acoustic transducer and ultrasonic transducer etc., and other sensors and drive
Dynamic device application.
The content of the invention
The goal of the invention of the present invention is to provide a kind of energy-conservation doorbell based on piezoelectric principle.The doorbell utilizes piezoelectric
Piezo-electric effect, is not required to battery and powers, and saves the energy, and long lifespan is cheap, can be widely applied to life.
The present invention realizes that its goal of the invention is adopted the technical scheme that：A kind of energy-conservation doorbell based on piezoelectric principle, bag
The PBU pushbutton unit and loudspeaker arrangement of doorbell are included, it is structurally characterized in that：The PBU pushbutton unit is by the consistent two panels piezoelectricity of polarised direction
Piece and the flexible insulating material layer composition for separating two panels piezoelectric patches；The two panels piezoelectric patches passes through between two opposite faces
Wire one is connected, and is connected between two relative faces of two panels piezoelectric patches by wire two；Connect in the wire one and wire two
Enter limited leakage resistance, inductance and loudspeaker arrangement.
The present invention principle and beneficial effect be：Two panels piezoelectric patches is separated with one layer of very thin insulating materials, by with pressure
Polarised direction unanimously arrange so that two panels piezoelectric patches compression situation is consistent.A piece of piezoelectric patches is being produced into electric charge just with wire
The negative pole that pole produces electric charge with another piezoelectric patches is connected, and the positive pole of the latter is connected with the former negative pole.Divide in circuit
The loudspeaker of current-limiting resistance, inductance and doorbell is not connected.Piezoelectric can produce instantaneous high pressure, and current-limiting resistance can be protected and raised one's voice
Device, inductance can also extend immediate current, and reaching responds the doorbell long period.Accessed in wire one and wire two limited
Leakage resistance, inductance and loudspeaker arrangement, can improve the operating efficiency of doorbell.When doorbell is by pressed by external force, two panels piezoelectric patches is simultaneously
Produce same moment polarization current so that doorbell produces the response of eclipsing effects so that efficiency increase.The doorbell utilizes piezoresistive material
The piezo-electric effect of material, is not required to battery and powers, and saves the energy, and the general stable long lifespan of piezoelectric performance, cheap, can be general
In applied to life.
Further, piezoelectric patches of the present invention is made up of piezoceramic material.
Compared with Common piezoelectricity materials, piezoelectric ceramics has electromechanical coupling factor high, and piezoelectric property controllability is good, chemistry
Property is stable, it is easy to prepare and the product of variously-shaped, size and arbitrary polarisation direction can be made, the advantages of cheap.
Further, piezoelectric patches of the present invention is made up of strontium titanates piezoceramic material.
Strontium titanates, with high dielectric constant and high refraction constant, has as important, emerging electron ceramic material
Significant piezoelectric property；Moreover, strontium titanates is lead-free ceramicses material, it is free from environmental pollution；Strontium titanates performance is stable, and it is used as piezoelectricity
Ceramic-type doorbell long lifespan, efficiency high.
Further, the flexible insulating material layer thickness of the present invention for being used to separate two panels piezoelectric patches is 1-2mm.
So, it can both ensure the insulation between two panels piezoelectric patches, cause that two panels piezoelectric patches compression situation is consistent again.
