Abstract

The utility model relates to a dual-functional household earthquake warner, which belongs to the field of electronic warner. The utility model not only can remind people of immediately evading when an earthquake takes place but also can be applied as a clock in the spare time, which is composed of a time telling electronic clock circuit, a doublet trigger alarm generating circuit, a Hall element, a magnet, a metal tube, a copper wire ring, a bracket, a spring and a regulating screw. The utility model is characterized in that: the spring, magnet and metal tube are connected in series by copper wire and then are connected with the regulating screw, while the Hall element is positioned near the magnet. As the technical plan is applied, the utility model has the advantages and active effects as follows: the technique of mechanical swing and electronic clock is mutually combined; tiny and nimble, artistic and practical and low in manufacturing cost.

Description

Two function earthquake siren for household

Affiliated technical field

The utility model relates to a kind of two function earthquake siren for household, belongs to the electronic alarm field, and it can not only reminds people in time be hidden when earthquake takes place, and can also use as clock at ordinary times.

Background technology

Seismic energy causes great disaster to people, and a lot of ruinous earthquakes in this case, if can in time hide, prevent, just can reduce a lot of losses all from small earthquakes.At present, existing earthquake siren for household, great majority all adopt the Metal Ball swinging technique, but function singleness.

Summary of the invention

The purpose of this utility model provides a kind of two function earthquake siren for household, makes to use as clock again at ordinary times in that the police of earthquake Times takes place.

The purpose of this utility model is achieved in that it is by the electronic clock circuit that gives the correct time. two triggering chimes of doom generation circuit, Hall element, magnet, metal tube, copper cash ring, support, spring, adjusting screw constitute.In circuit, power supply is connected with mechanical switch, the power input of electronic clock circuit when power positive cathode is informed of a case, sound output and the two chimes of doom generation circuit audio signal output terminals that trigger of electronic clock circuit of giving the correct time connect loudspeaker, the silicon controlled anode. after linking, an end and the Hall element of resistance connect with mechanical switch, the controllable silicon negative electrode connects two power inputs that trigger chimes of doom generation circuit, the silicon controlled trigger electrode with connect Hall element after the other end of resistance links to each other, during concrete enforcement, circular spirit bubble is placed on the appropriate location above the shell, adjusting knob is placed on appropriate location, the shell back side, be used to regulate the level of shell, outer casing frontispiece is placed clock pointer, loudspeaker are placed in the appropriate location in the enclosure. support, it is characterized in that: with spring, magnet, metal tube links to each other with adjusting screw with copper cash series connection back, places Hall element near magnet.Metal tube is pressed the circuit elements device annexation of Fig. 1 and is welded in the circuit board with the stainless steel material that is difficult for oxidation.

The utility model is owing to adopt technique scheme, and the advantage and the good effect that are had are: mechanical pendulum braking technique and electronic clock technology combine, and be small and exquisite nimble, both artistic and practical, and cost is not high yet.
