Description
Technical field
This utility model is related to a kind of doorbell, more particularly to a kind of energy-conservation doorbell of the piezoelectric effect of utilization piezoelectric.
Background technology
Present door bell for anti-theft door is mostly to use battery or directly using the electronic door bell of electricity, because of the terminal voltage of aneroid battery,
Extending with use time and being gradually reduced, and affect doorbell normal work, while can also cause environment pollution.It is estimated, mesh
The battery level of front doorbell is about 7.896 hundred million sections.It is apparent that the battery level of doorbell is one and opens greatly very much according to analysis
, while the harm to environment is also larger.And electronic door bell has energy expenditure and frequently changes battery, with society
Understand 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
Can there is voltage between both ends of the surface in the masterpiece used time, and this is caused based on piezoelectric effect.Piezoelectric effect refers to that some electrolytes exist
When above being deformed by the effect of external force in a certain direction, polarization phenomena can be produced inside it, while in the relative table of its two
Occurs positive and negative contrary 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 piezoquartz and piezoelectric ceramics, and piezoquartz is usually
Refer to piezoelectric single crystal；Piezoelectric ceramics then refers to piezoelectricity polycrystal.Piezoelectric ceramics refer to mixed with the raw material of necessary composition, into
Type, high temperature sintering, the fine-grain irregular collective obtained by solid state reaction and sintering process between powder it is many
Crystal.Also known as piezopolymer, such as Kynoar (PVDF) (thin film) and other with it as representative have organic piezoelectric materials
Machine piezoelectricity (thin film) material.Now the application of piezoelectric can be roughly classified into two big class:That is vibrational energy and supersonic vibration
Energy-electric energy transducer application, including electroacoustic transducer, underwater acoustic transducer and ultrasonic transducer etc., and other sensors and drive
Dynamic device application.
Utility model content
Goal of the invention of the present utility model is to provide a kind of energy-conservation doorbell.The doorbell utilizes the piezoelectric effect of piezoelectric,
It is not required to battery to power, energy saving, life-span length is cheap, can be widely applied to life.
This utility model realizes that its goal of the invention is adopted the technical scheme that：A kind of energy-conservation doorbell, including doorbell presses
Button device and loudspeaker arrangement, it is structurally characterized in that：The pushbutton unit by the consistent two panels piezoelectric patches of polarised direction and for every
Open the flexible insulating material layer composition of two panels piezoelectric patches；Pass through the phase of wire one between two opposite faces of the two panels piezoelectric patches
Even, it is connected by wire two between two relative faces of two panels piezoelectric patches；Current limiting is accessed in the wire one and wire two
Resistance, inductance and loudspeaker arrangement.
Principle of the present utility model and beneficial effect are：Two panels piezoelectric patches is separated with one layer of very thin insulant, by with
The polarised direction of pressure is unanimously arranged so that the pressurized situation of two panels piezoelectric patches is consistent.A piece of piezoelectric patches is produced into electric charge with wire
Positive pole and another piezoelectric patches produce the negative pole of electric charge and couple together, the positive pole of the latter is connected with the former negative pole.In circuit
The middle speaker for connecting current-limiting resistance, inductance and doorbell respectively.Piezoelectric can produce instantaneous high pressure, and current-limiting resistance can be protected and raised
Sound device, inductance can also extend immediate current, and reaching responds the doorbell long period.Accessing in wire one and wire two has
Current-limiting resistance, inductance and loudspeaker arrangement, can improve the work efficiency of doorbell.When doorbell receives pressed by external force, two panels piezoelectric patches is same
When produce same moment current of polarization so that doorbell produce eclipsing effects response so that efficiency increase.The doorbell utilizes piezoelectricity
The piezoelectric effect of material, is not required to battery and powers, energy saving, and general piezoelectric stable performance life-span length, cheap, can
In being widely used in life.
Further, piezoelectric patches described in the utility model 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
It is stable in properties, it is easy to the product of variously-shaped, size and arbitrary polarisation direction to be prepared and can be obtained, the advantages of cheap.
Further, piezoelectric patches described in the utility model 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；And, strontium titanates is lead-free ceramicses material, free from environmental pollution；Strontium titanates stable performance, it is used as piezoelectricity
Ceramic-type doorbell life-span length, efficiency high.
Further, the flexible insulating material layer thickness for separating two panels piezoelectric patches described in the utility model is 1-2mm.
So, the insulation between two panels piezoelectric patches had both been can ensure that, has caused the pressurized situation of two panels piezoelectric patches consistent again.
