Abstract
The utility model relates to a watch degausser which comprises a coil with an iron core, wherein, the coil is connected with 220V power source and is provided with a switch. The utility model is characterized in that a thermistor is connected in series with the coil. The utility model can obtain an automatic attenuation alternating magnetic field through the thermistor, so the utility model has the advantages of convenient operation, energy saving, simple structure, low cost and large degaussing range. A watch with a high magnetizing degree can be also reliably degaussed.
Description
The utility model relates to a kind of wrist-watch demagnetizer.
In a single day stem-winder is magnetized, just lost its accuracy, so people have invented multiple method and the device that makes the wrist-watch degaussing of having magnetized, for example the coil with a ribbon core inserts the 220V alternating current, set up a constant amplitude alternating magnetic field, wrist-watch is moved at home and abroad from this magnetic field, to reach the purpose of degaussing.Can also pass through AC voltage regulator, make the 220V voltage of output be reduced to 0 gradually.These two kinds of methods all are to make the alternating magnetic field that obtains a decay on the table part come degaussing, first method trouble, route that moves and the bad grasp of distance; Second method is used the equipment complexity, generally do not possess this condition, and these two kinds of methods is all wasted electric energy.
The purpose of this utility model provides a kind of wrist-watch demagnetizer of new structure, and its equipment is simple, and is easy to use, and can reach the purpose of economize on electricity.
The purpose of this utility model is achieved in that it comprises a coil that has iron core, connects the 220V power supply and also switch is housed, and a thermistor is characterized in that connecting with coil.
The utility model adopts the thermistor with positive temperature control number, obtains an alternating magnetic field of decay automatically, so simple to operate, and because thermistor energising back resistance increases current attenuation, working time weak point simultaneously suddenly, so, reach purpose of energy saving than adopting constant interchange power saving.The utility model adopts the secondary demagnetizing method, has the big advantage of demagnetization scope, for the higher also degaussing reliably of table of magnetization degree.The utility model is simple in structure in addition, and cost is low.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
1 is coil among the figure, and iron core 2 is housed in the coil, is in series with the thermistor RT of positive temperature coefficient (PTC) with coil, and power supply adopts the 220V alternating current, and K switch is housed.
When wrist-watch demagnetizer of the present utility model uses, only switch need be pulled, just degaussing work can be finished automatically.
