Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 3, 4, shown in 5, a kind of doorbell with spontaneous electrical function, comprise self power generation module 4, the control circuit controlling doorbell work and the electric energy conversion module electrical energy pulse of self power generation CMOS macro cell converted to for control circuit work, described electric energy conversion module includes current rectifying and wave filtering circuit, described current rectifying and wave filtering circuit is set to half-wave rectifying circuit, and include diode D1 and filter capacitor C2, the positive terminal of diode D1 connects the output terminal of self power generation module, the negative pole end of diode D1 connects one end of filter capacitor C2, the other end ground connection of filter capacitor C2, the two ends of filter capacitor C2 export the voltage after rectifying and wave-filtering, flow to the Voltage stabilizing module 3 etc. at rear.Diode D1 is schottky diode, and the voltage after rectifying and wave-filtering outputs to control circuit through Voltage stabilizing module 3 process.The handle 5 that self power generation module comprises Electromagnetic generation assembly and can move reciprocatingly, self power generation module produces electrical energy pulse according to handle to-and-fro movement.Electromagnetic generation assembly comprises base 9, base is arranged magnetic conduction skeleton 8, magnetic conduction skeleton is arranged with power coil 7, the side of power coil arranges permanent magnet 6, and described permanent magnet 6 is arranged in described handle 5, described permanent magnet 6 according to the to-and-fro movement of handle away from or near power coil.Base 9 is provided with the fluting moved up and down for handle, between described handle and base, is provided with returning spring.
In its this series products of tangible doorbell, do not need the whole cycle being applied to electricity generation module, the normal use of the voltage that its half period produces enough doorbell.Due in full-wave rectifying circuit, the conduction voltage drop of diode bridge heap can be higher, and the pressure drop of a general-purpose diode is at about 0.8V, then have the loss of voltage of 1.5V with the rectification circuit that the method is built, conversion efficiency is lower.
Rectification circuit is arranged to half-wave rectifying circuit by the utility model, the electrical energy pulse that handle 5 action produces, DC voltage is drawn after electric capacity C filtering after filtering again by schottky diode D rectification, then through follow-up voltage stabilizing process etc., the control circuit work of supply doorbell.Because this scheme is half-wave rectification, so need to consider voltage direction, although handle only produces an electric energy in the whole action cycle and powers, but because it adopts a diode, and employing schottky diode, the forward voltage drop of schottky diode is 0.4V, the about 0.4V of loss pressure drop, in this half period, if the electrical energy pulse amplitude that self power generation module produces is between 6-10V, then this half period internal conversion voltage amplitude is out at 5.6V-9.6V, and conversion efficiency, between 93-96%, decreases electric energy loss.Compared to the conversion efficiency of full-wave rectification in this half period, be improved largely.
In addition, the magnetic size of the permanent magnet 6 in the main and handle 5 of the amplitude of the electrical energy pulse produced due to self power generation module and the number of turns of power coil proportional, namely the magnetic of permanent magnet 6 number of turn that is less or power coil 7 is fewer, then electrical energy pulse amplitude is less, if therefore need identical output voltage, can reduce the volume of corresponding permanent magnet, the number of turn of power coil, then corresponding magnetic conduction skeleton 8, base 9 all can reduce accordingly, and overall volume also reduces thereupon.The original component number of half-wave rectifying circuit decreases, and indirectly reduces components and parts cost, and the space taking pcb board also reduces to some extent.The voltage that the electric energy that self power generation module produces does not need too much counteracting to lose because of rectifying and wave-filtering part, therefore can reduce the amplitude of the potential pulse of self power generation module, thus the also corresponding reduction of the pressing force of self power generation module, volume.Such as when control circuit needs 7V voltage, if employing prior art, self power generation module needs the voltage producing 8.5V, then power coil needs the number of turn of about 1000 circles, and the size of whole self power generation module is approximately 30*26*9mm volume and is approximately 7 cubic centimetres.When adopting the technical solution of the utility model, self power generation module only needs the voltage producing about 7.4V, the power coil number of turn is approximately the number of turn of 870 circles, the volume of whole self power generation module can approximately reduce to 6.1 cubic centimetres, size is approximately 26*26*9mm, and the manufacturing cost of product also can reduce accordingly.
