Abstract

The utility model relates to a calling device, particularly a dual-purpose door bell. The utility model is composed of a button, a socket, a boiled water alarm sensor, a current loop and relative electric bell elements. The calling device can sound different sounds according to the length of time when the button is pressed, the interruption of the button, and different button pressing times, and thus different comers are identified; at the same time, the calling device can be used as a boiled water alarm when a bolt is inserted. The utility model has the advantages of simple structure, easy fabrication, low cost, high reliability, one object with multifunction, and convenient operation.

Description

Dual purpose doorbell

The utility model relates to a kind of calling device, particularly Dual-purpose door bell.

In existing Electric door bell, generally all can not send unlike signal offering an explanation out different messengers, the music door-bell that has, though can play out the music sound, expensive price, and the sound equipment time immobilizes; In addition, general doorbell can only be special-purpose, can not doublely do his usefulness, so convenient inadequately.

The purpose of this utility model is will provide a kind of can send the doorbell of different length sound equipments, and can be used as the boiling water warning device according to the signal of making an appointment, thereby can be offered an explanation out different messengers and be reached the purpose of one-object-many-purposes by the doorbell sound.

The purpose of this utility model is achieved in that in this device and includes socket, button, the boiling water alarm sensor, current return and the battery that is installed in enclosure interior, coil, hammer stem, spring leaf, the bell body, when pressing button, during coil electricity, hammer stem is attracted to hit the bell body by coil, meanwhile, the contact that spring leaf links to each other with hammer stem is left, current interruptions, hammer stem sets back, circuit is connected once more, and hammer stem is attracted by coil again, carries out so repeatedly, its the tinkle of bells constantly and with the length of pressing the button time changes, thereby can offer an explanation out different messengers by prior previously arranged signal.In addition, in this electric bell loop, and link the boiling water alarm sensor, this alarm sensor is enclosed within on the handle of pot lid, when utilizing boiling water, one end of water vapor stream jack-up vane and the other end of vane descends, contact with the contact chip that is positioned at this end, the conducting electric current promptly is equivalent to press button with hand, so send the tinkle of bells, thereby water is opened as can be known.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Describe specific structural details of the present utility model and working condition thereof in detail below in conjunction with Fig. 1,2,3,4.

Dual-purpose door bell includes socket 1, button 2, the boiling water alarm sensor, current return and the coil 4 that is installed in housing 16 inside, battery 3, hammer stem 5, spring leaf 6, bell body 18 all elements, housing 16

inner spring sheets

6 and 5 of hammer stems accompany insulating trip 7, just the contact 8 on the spring leaf often is in closure state with hammer stem 5, the hammer stem end is near one of coil 4 end, when pressing button 2, current lead-through, hammer stem 5 is attracted by coil magnet, so tup impacts bell body 18, meanwhile the contact 8 on hammer stem 5 and the spring leaf is separated, current interruptions, hammer stem 5 sets back, and at this moment circuit is connected once more, and hammer stem 5 is attracted by coil magnet again, tup impacts bell body 18 once more, carry out so repeatedly, the length that its jingle bell time is pressed the time with button 2 changes, and debates not different messengers thereby can press the interrupted and different number of times of length of button time according to prior agreement.

When this doorbell double as boiling water alarm used, then in the current return of doorbell, socket 1 in parallel was connected itself and boiling water alarm sensor, as shown in phantom in Figure 1.The boiling water alarm sensor be by one have hole 10 in case be enclosed within insulcrete 11 on the kettle lid handle, insulcrete have for 11 times the middle part frame on the transverse axis 19 fixing by screw 13 and two ends can free oscilaltion vane 12, constituted by fixing U-shaped contact chip 9 of screw 13 and the current return that is communicated with socket 1 near vane one end; Promptly be installed on the socket 17 on the insulcrete 11, with the loop-coupled socket 1 of doorbell so that under socket, be hinged with electric wire.Insulcrete promptly is to use the screw 13 of the different length that is suitable for kettle top curvature to be supported on the Hu Ding, and the also double device that fixes of the screw that has uses.

During use, with the circular hole 10 on the insulcrete 11 of sensor, be enclosed within on the handle of pot lid, and make pore on the pot lid 15 aim at the end of vanes away from contact chip 9, in the ordinary course of things, make this end level height of vane be lower than a end slightly near contact chip 9, the latch that will connect the doorbell circuit then inserts in the socket 1, when water was opened in the kettle, water vapor circulation air passing hole 15 impulsion vanes 11 made this end perk of vane, and the other end of vane descends, and contact with contact chip 9, so make the circuit turn-on that leads to socket 1 that connects vane 12 and contact chip 9, bell ring is reported to the police, usually time spent not, then can take out latch, take off alarm sensor, doorbell still can use as usual.

The utility model is simple in structure, and is easy to manufacture, with low cost, reliable for effect, thereby both can having sent unlike signal, doorbell offered an explanation different messengers, arbitrarily its double water boiling alarm of doing that makes in parallel with the water boiling alarm sensor uses again, one-object-many-purposes, easy to use, promote easily.

Claims

1, a kind of calling device, particularly Dual-purpose door bell include socket, button, boiling water alarm sensor, current return and are installed in battery, coil, hammer stem, spring leaf, the bell body of enclosure interior, it is characterized in that:

(1) housing inner spring sheet upper contact and hammer body bar often are in closure state, and an end of hammer stem is near one of coil end;

(2) tup on the hammer stem is near the bell body, and when tup hit the bell body, the spring leaf upper contact separated with hammer stem;

(3) in the doorbell current return, socket is housed, links to each other by the loop of latch with the boiling water alarm sensor.
