Description
Technical field
The utility model is related to a kind of energy-conservation doorbell, more particularly to a kind of energy-saving doors of the piezo-electric effect of utilization piezoelectric
Bell.
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.
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 piezo-electric effect of piezoelectric,
It is not required to battery to power, saves the energy, long lifespan is cheap, can be widely applied to life.
The utility model realizes that its goal of the invention is adopted the technical scheme that：One kind energy-conservation doorbell, including button assembly
With the sounding component for producing audible signal, it is structurally characterized in that：The button assembly is by the consistent two panels titanium of polarised direction
Sour potassium sodium bismuth piezoelectric patches and for separate two panels bismuth sodium potassium titanate piezoelectric patches thickness be 1-2mm flexible insulating material layer group
Into；The two panels bismuth sodium potassium titanate piezoelectric patches is connected between two opposite faces by wire one, two panels bismuth sodium potassium titanate piezoelectricity
It is connected between two relative faces of piece by wire two；Access has sounding component in the wire one and wire two.
Principle and beneficial effect of the present utility model are：Bismuth sodium potassium titanate piezoelectric be one kind can realize mechanical energy and
The functional material that electric energy is mutually changed.Piezoelectric voltage can occur when being under pressure effect between both ends of the surface, and this is to be based on
Caused by piezo-electric effect.When piezo-electric effect refers to that some dielectrics are deformed in a certain direction by the effect of external force, its
Inside can produce polarization phenomena, while there is positive and negative opposite electric charge on its two apparent surfaces.After external force is removed, it
Uncharged state can be returned to again.
Two panels bismuth sodium potassium titanate piezoelectric patches is separated with one layer of very thin insulating materials in the utility model, the polarization of pressing force
Direction is unanimously arranged so that two panels bismuth sodium potassium titanate piezoelectric patches compression situation is consistent.A piece of piezoelectric patches is produced into electric charge with wire
Positive pole and another piezoelectric patches produce electric charge negative pole connect, the positive pole of the latter is connected with the former negative pole.Bismuth titanates
Sodium potassium piezoelectric patches piezoelectric can produce instantaneous high pressure, make door bell rings should.When doorbell is by pressed by external force, two panels bismuth sodium potassium titanate
Piezoelectric patches produces same moment polarization current simultaneously so that doorbell produces the response of eclipsing effects so that efficiency increase.Experiment is tested
Card, thickness can both ensure the insulation between two panels bismuth sodium potassium titanate piezoelectric patches for 1-2mm flexible insulating material layer, cause again
Two panels piezoelectric patches compression situation is consistent.The doorbell utilizes the piezo-electric effect of piezoelectric, is not required to battery and powers, and saves the energy, and
The general stable long lifespan of piezoelectric performance, it is cheap, it can be widely applied in life.
Compared with Common piezoelectricity materials, bismuth sodium potassium titanate piezoelectric has dielectric coupling coefficient high, and piezoelectric property is adjustable
Section property is good, and chemical property is stable, it is easy to prepare and the product of variously-shaped, size and arbitrary polarisation direction can be made, price is low
Honest and clean the advantages of.Bismuth sodium potassium titanate piezoelectric patches is lead-free ceramicses material, free from environmental pollution, and performance is stable, and it is used as piezoelectric ceramic type
Doorbell long lifespan, efficiency high.
Sounding component described in the utility model includes current-limiting resistance, inductance and Microspeaker.Connect respectively in circuit
The Microspeaker of current-limiting resistance, inductance and doorbell.Current-limiting resistance can protect Microspeaker, and inductance can also prolong immediate current
It is long, the effect of Microspeaker response for a long time is reached, the operating efficiency of doorbell is improved.
Further, the PBU pushbutton unit of doorbell of the present invention is installed on a door or wall on, PBU pushbutton unit and door or wall
Between compression spring is installed.
Compression spring can be used for providing stroke when ringing a doorbell, Consumer's Experience when enhancing is rung a doorbell, while allowing piezoelectric patches
It is more uniformly stressed.
Further, the coefficient of elasticity of compression spring of the present invention is 400-2000N/m.
Shown according to experiment, finger is rung a doorbell, and provided pressure is general in 4N or so, and selection coefficient of elasticity is 400-
2000N/m compression spring can both ensure preferable Consumer's Experience, and piezoelectric patches stress can be taken into account again and installing space limitation is asked
Topic.
Brief description of the drawings
Fig. 1 is the utility model embodiment circuit theory schematic diagram.
