Description

A kind of household alarm

Technical field

The utility model relates to a kind of anti-alarm of usurping, especially a kind of household alarm.

Background technology

Society is improving, and is economical in development.Along with the enhancing of the antitheft consciousness of people, various burglar alarms also arise at the historic moment, and its designs and varieties are various, and are machinery, electronics, optics, computer, multifarious, complete; But its structure is generally all very complicated, and cost is also high.For consumers in general, press for a kind of economical and practical burglar alarm that makes things convenient for and can be placed on any position again.Chinese patent ZL90108307.0 discloses a kind of alarm for door opening, it comprises trigger unit, the loudspeaker that is contained in the circuit of the generation alerting signal in the rectangular parallelepiped shell and sounds and report to the police, the rectangular parallelepiped shell is contained on the door, wherein trigger unit is by the slide fastener that is contained on the doorframe, be arranged in a T-slot of rectangular parallelepiped shell, the tilting spring foil metal that is positioned at the T-slot inboard constitutes with the electricity level that is positioned at T-slot, the free end of slide fastener comprises a T shape pin, T shape pin inserts in the T-slot during use, when door is opened, impel T shape pin to slide along T-slot, spring foil metal is depressed by T shape pin and is touched electrode, the circuit that produces alerting signal is connected, and loudspeaker sends chimes of doom.The alarm of this scheme also is that the slide fastener with trigger unit is contained on the doorframe, promptly is fixed on the door and window equally with whole alarm, can not arbitrarily move, and the thief only notes and do not run into the switch position after being taken in for the first time, can keep away alarm next time.

Summary of the invention

The purpose of this utility model is to solve the problem of above-mentioned existence, provides a kind of make things convenient for arbitrarily to move, and is simple in structure, can make the hard to guard against alarm of thief.

The technical solution of the utility model is achieved in that it comprises the housing that is shoe-shaped and is installed on the power supply that composes in series warning device in regular turn, trigger switch, control circuit and loudspeaker in the housing, wherein loudspeaker is loaded on upper of a shoe inside, trigger switch is located at heel near the upper of a shoe place, and control circuit is loaded on enclosure interior and loudspeaker and trigger switch and joins.

Mobile alarm device and warning for convenience, described trigger switch is made of the spring and the switch S 1 of joining with button being located at the button that is ramped shaped on the housing and being positioned at housing, one end of described switch S 1 is located on the power circuit, the other end is located on the control circuit, and spring is located between housing inner bottom surface and the button.

It is loud to send chimes of doom for convenience of loudspeaker, and the vamp of the position of corresponding loudspeaker is provided with several sound holes on the described housing.

The utility model makes alarm can arbitrarily move any position that is placed on door and window because trigger switch is located on the alarm housing, makes the person of forcing open the door hard to guard against; Because the button of trigger switch is ramped shaped, in use, alarm is placed on the door and window back, and when the person of forcing open the door pushed, doorframe was pressed in and makes alarm will send chimes of doom on the button; When not using at ordinary times, only need remove alarm and get final product; Therefore the utility model is easy to use, simple in structure.

Below in conjunction with accompanying drawing the utility model is further described.

Embodiment

As shown in Figures 1 and 2, the utility model comprises the housing 1 that is shoe-shaped and is installed on the power supply that composes in series warning device in regular turn, trigger switch, control circuit and loudspeaker in the housing, wherein loudspeaker 3 is loaded on upper of a shoe inside, trigger switch 4 is located at heel near the upper of a shoe place, and control circuit 2 is loaded on housing 1 inside and joins with loudspeaker 3 and trigger switch 4.Mobile alarm device and warning for convenience, described trigger switch 4 is made of the spring 42 and the switch S 1 of joining with button 41 being located at the button that is ramped shaped 41 on the housing 1 and being positioned at housing 1, one end of described switch S 1 is located on the power circuit, the other end is located on the control circuit 2, and spring 42 is located between housing 1 inner bottom surface and the button 41.Loudspeaker sends chimes of doom for convenience, and the vamp of the position of corresponding loudspeaker 3 is provided with several sound holes 5 on the described housing 1; The control circuit 2 that wherein said control loudspeaker 3 sends chimes of doom comprises: interface IC, resistance R 1, triode Q1 and the oscillatory circuit of being made up of diode D1 and inductance L 1, described switch S 1 is connected between the supply pin VDD and power supply of interface IC, when switch S 1 is pressed, power supply is supplied the 3V power supply through ic chip to ic chip, high level signal turn-on transistor Q1 of the OUT output pin of ic chip output sounds loudspeaker (3) thereby produce oscillator signal by inductance L 1 and diode D1 under the situation of triode Q1 conducting then.

As shown in Figure 1 and Figure 2, housing 1 of the present utility model is designed to the shoe-shaped structure, and the button 41 of trigger switch 4 is ramped shaped, and spring 42 is located at housing 1 inside, be clipped between button 41 and housing 1 inner bottom surface, the two ends of switch S 1 are connected between power supply and the control circuit 2.During use, the heel of a shoe of slippers is placed in the crack of door and window, the front end and the doorframe of button 41 join, and when the person of forcing open the door pries open door when pushing, doorframe is with the slope direction of button 41, be pressed in from bottom to top on the button 41, switch S 1 is pressed to electrode by spring 42, switch S 1 conducting, and supply voltage flows into oscillatory circuit by triode Q1, produce audio frequency by the circuit that shakes again and send into loudspeaker 3, make loudspeaker 3 send chimes of doom; In the time need not using at ordinary times, only need alarm taken away and get final product, needn't as fixing alarm, multiple setting to be passed through and chimes of doom could be do not sent.The utility model can also use in places such as drawer, automobile doors simultaneously.
