Abstract
The invention relates to a double-fuse mechanism, particularly to a double-fuse mechanism especially for various home appliances. The double-fuse mechanism comprises a work fuse, a spare fuse and a contactor, wherein the spare fuse and the contactor are in parallel connection with the work fuse. The double-fuse mechanism has the following advantages: 1. the mechanism is low in cost; and 2. the time for using the fuse without replacement can be doubled, thereby bringing more convenience to users.
Description
Technical field
The present invention relates to a kind of double safety mechanism, relate in particular to the double safety mechanism of a kind of specialty for various household electrical appliance.
Background technology
Now domestic various household electrical appliance all can be used protective tube, employing be all the mechanism of simple insurance, that is to say only with a protective tube.Due to a variety of causes, protective tube can be burned, and causes household electrical appliance normally to use.Need to change protective tube, but because user does not nearly all have electrician's basis, some electrical equipment is changed protective tube certain difficulty (as reasons such as installation sites), because service engineering teacher is in the replacing of protective tube the inconvenience that seems of making house calls, and can produce certain expense.
Summary of the invention
For the weak point of above-mentioned technology, the invention provides a kind of simple method, in the situation that increasing cost hardly, make the time of changing can extend one times.
A kind of double safety mechanism, comprises work insurance pipe, and the standby protective tube, the contactor that are connected in parallel with work insurance pipe.
Wherein, described contactor comprises static iron core, moving iron core, coil, spring.
Beneficial effect of the present invention is, first, this mechanism cheap (cost is no more than 5 yuan), secondly, the time of changing fuse can extend one times.Person easy to use widely.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A kind of double safety mechanism, as shown in Figure 1, comprises work insurance pipe 2, in addition, also comprises the standby protective tube 1, the contactor 3 that are connected in parallel with work insurance pipe 2.
Wherein, described contactor 3 comprises static iron core 4, moving iron core 6, coil 5, spring.
Simply introduce the operation principle of contactor, electrical equipment energising under normal circumstances, as shown in Figure 3, and A coil, B coil electricity, static iron core 4 produces magnetic field, and down, contact C and D disconnect the elastic force that moving iron core 6 overcomes spring; In the time that work insurance pipe 2 burns out, A coil, B coil no power, static iron core 4 does not produce magnetic field, and under spring action up, contact C and D connect moving iron core 6, backup fuse work, household electrical appliance normally use, as shown in Figure 2.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
Claims (2)
1. a double safety mechanism, comprises work insurance pipe, it is characterized in that, also comprises the standby protective tube, the contactor that are connected in parallel with work insurance pipe.
2. structure as claimed in claim 1, is characterized in that, described contactor comprises static iron core, moving iron core, coil, spring.
