Abstract
The utility model relates to an automatic electric breaking switch which is especially suitable for domestic appliances. The automatic electric breaking switch is composed of a case body, an inductance, a button, a rotating shaft, a spring and a steel disc. When the power is cut off suddenly, the automatic electric breaking switch can automatically cut off the power to avoid the instant high voltage damaging electric appliances after the power switches on. When nobody is in the house, the automatic electric breaking switch can avoid a waste of electricity. The automatic electric breaking switch has the advantages of simple structure, high safety, high reliability, low cost, energy saving and domestic appliances protecting.
Description
The utility model relates to a kind of automatic power-off switch, is specially adapted to the automatic power-off switch that household electrical appliance are used.
At present in the society generally the switch of usefulness all be people's hand control, in use have a power failure suddenly as fortuitous event, forget the pass swap switch after the power failure, when sending electricity again, the high pressure that moment produces just damages electrical equipment easily, if electric light, people are not in time closed swap switch, when again the incoming call and indoor nobody the time, will waste.
The purpose of this utility model is to avoid above-mentioned deficiency and a kind of automatic power-off switch of providing.
Below in conjunction with accompanying drawing formation of the present utility model is described further: Fig. 1 is the structure chart and the front view of automatic power-off switch, automatic power-off switch, form by box body (1), lid (2) button (3), inductance (4), spring (5), it is characterized in that being equipped with on the box body (1) fixed rotating shaft (7), button (3) can rotate around it, and a spring (5) and inductance (4) and steel disc (9) are housed in the box body (1).Spring (5) one ends are fixed on the box body (1), and the other end closes side with button (4) and is connected.Inductance (4) one ends are fixed on the box body (1), and a contact (6) is installed on the other end, and an iron plate (10) is installed at the beginning place of button (3).Button (3) is gone up processing 1 prominent point (8), and adjacent with the steel disc that is fixed on box body (1) (9), one that steel disc (9) is adjacent with prominent point (8) is processed with a flex point.
Box body (1) can not only prevent electric leakage, and is the support that each parts is installed.Leave a square hole in the middle of the lid (2), be used for installing button (3), lid (2) is connected with screw with box body (1).Button (3) is fixing with a fixed rotating shaft (7) and box body (1), and be axle with fixed rotating shaft (7), presses button (3), " opening " or " pass " of realization switch.Spring (5) one ends link to each other with box body (1), and the other end is connected with the pass side of button (3).Inductance (4) one ends are fixed on the box body (1), and the contact of the other end (6) is with respect to the iron plate (10) of button on (3) beginning.The end that steel disc (9) is adjacent with button (3) has a flex point, can be used to block the prominent point (8) on the button (3).
During use, connect circuit, " the opening " of pressing switch, at this moment iron plate (10) contact with contact (6), at this moment owing to electricity is arranged, in the inductance (4) electric current is arranged and produces magnetic pull, holds iron plate (10), makes switch be in "open" state.In case have a power failure, the magnetic pull of inductance (4) disappears, and switch is got back to the position of " pass " at once automatically under the effect of spring (5).The flex point of steel disc (9) is at this moment just in time blocked the prominent point (8) on the button (3), so no matter sends a telegram here when, unless just go Push switch to switch on by the people, otherwise switch is in "off" state always.So just can guarantee that electrical equipment is not subjected to the damage of instantaneous high pressure, and energy savings, prolong the useful life of electrical equipment.
The utility model is simple in structure, and is safe in utilization, and reliable, cost is low, and can save energy consumption, protection electrical equipment.
