Description

Fire extinguisher automatic speech explanation device

The utility model is about a kind of electronic speech device, particularly about a kind of fire extinguisher automatic speech explanation device.

More therefore and burnt along with improving constantly of modern's awareness of safety, more and more high for the requirement of the security of living environment, but still have many things to be still can't to grasp, fire is unpredictable natural and man-made calamities wherein, and many people.In fact, some fire is avoidable, if inevasible, if can take place at that time at fire, in time puts out burning things which may cause a fire disaster, just can avoid a unexpected calamity.

Fire extinguisher promptly be a kind of save from damage individual family background property indispensable a kind of equipment, but when urgent the use,, and make it can't bring into play the fire-extinguishing function concurrently that this has but often because of the user does not know how to operate fire extinguisher.Especially when very urgent, again because of there not being enough light in the scene of a fire, or under smoky situation, cause the user can't see operational manual on fire extinguisher clearly, thereby forfeiture fire extinguishing good opportunity causes fire extinguisher can't put out fire in the scene of a fire timely and effectively.

Main purpose of the present utility model provides a kind of fire extinguisher automatic speech explanation device, even in the scene of a fire, do not have enough light or under smoky environment, the utility model is all unaffected, and the user can be provided a kind of speech explanation that makes the step that sprays fire extinguisher.

Another purpose of the present utility model provides a kind of through rocking promptly the fire extinguisher speech explanation device of play operation step automatically.

The utility model is achieved in that installing one speech explanation device on a fire extinguisher, and comprising: a supply unit provides required power supply; One gauge tap connects above-mentioned supply unit; Spring is pressed and is rocked switch, connects above-mentioned gauge tap; One capacitor connects above-mentioned spring pressure and rocks switch; One speech IC connects above-mentioned capacitor, during power turn-on, drives this speech IC, to export a specific signal; One voice amplifying circuit receives the signal that above-mentioned speech IC is exported, and sends out an amplifying signal; And a sound-producing device, connect above-mentioned voice amplifying circuit, to receive this amplifying signal that it is spread out of.

Described supply unit is a battery.

Described voice amplifying circuit comprises a variable resistance and an output amplifier, and described variable resistance connects a volume control switch, with the size of control volume.

Described sound-producing device is a compact horn.

The utility model is voice of recording the emergency operation method of this type fire extinguisher in a speech IC, rock switch in conjunction with spring pressure, and be made into a micro metal box or a plastic box, it is installed on the fire extinguisher, to allow the user when picking up fire extinguisher, this speech explanation device pronunciation automatically tells the user should how to operate this fire extinguisher, to allow the consumer who buys this fire extinguisher obtain bigger guarantee.

The effect that describes the purpose of this utility model, technology contents, characteristics in detail and reached by the specific embodiment conjunction with figs. below.

Fig. 1 is a three-dimensional appearance schematic diagram of the present utility model.

Fig. 2 is an electrical block diagram of the present utility model.

Fig. 3 is a speech explanation schematic representation of apparatus of the present utility model.

Fig. 4 presses the structural representation that rocks switch for spring of the present utility model.

Referring to three-dimensional appearance schematic diagram of the present utility model shown in Figure 1, it is installing one a speech explanation device 12 on a fire extinguisher 10, this speech explanation device 12 is installed on the fire extinguisher 10 in the mode of pasting, and speech explanation device 12 is recorded different speech explanation books at multi-form fire extinguisher 10, so be applicable to the various fire extinguishers 10 on the market; Speech explanation device 12 also can directly directly be installed on the fire extinguisher 10 when making, and need not install in addition again.

Referring to electrical block diagram of the present utility model shown in Figure 2, in this circuit structure, a supply unit is a battery 14, connects a gauge tap 16, to set opening or closing of power supply; Other has spring pressure to rock switch 18, is activated at once through rocking promptly, and this spring is pressed and rocked switch 18 connections one capacitor 20, when power supply is switched on, promptly this capacitor 20 is charged; One electronic speech integrated circuit 22 connects above-mentioned capacitor 20, and connects the voice amplifying circuit 24 of a gain adjustable (gain); One sound-producing device is a compact horn (speaker) 26, connects above-mentioned voice amplifying circuit 24, to be combined into a speech explanation device.Wherein, above-mentioned voice amplifying circuit 24 is made up of a small-sized variable resistance 28 and an output amplifier 30, and this variable resistance 28 connects a volume control switch, can control the size of output volume.

When gauge tap 16 is the situation of opening, the spring pressure is rocked switch 18 and is rocked, make power turn-on, capacitor 20 just begins charging, so that enough this electronic speech integrated circuits 22 of driven by power to be provided, exporting a signal specific to voice amplifying circuit 24, this signal specific is amplified and spread out of an amplifying signal to compact horn 26, make it send the special sound of the fire extinguisher operation instruction that electronic speech integrated circuit 22 recorded.

Referring to speech explanation schematic representation of apparatus of the present utility model shown in Figure 3, this speech explanation device 12 is in a small-sized box 34, it is a can or plastic box, each element of installing foregoing circuit structure, and be provided with a plurality of through holes 36 on the surface of this speech explanation device 12, the voice that compact horn is sent can be known to be played out.And above-mentioned volume control switch 32 is installed in a side of speech explanation device 12, with the size of control voice output volume.

Spring press rock switch 18 structure as shown in Figure 4, a location pedestal 38 is provided with a positioning rod 40 in the middle of it, other has a spring 42 to connect positioning pedestals 38, and around backstay 40, the purpose of backstay 40 promptly when providing spring 42 to rock from side to side, unlikely departing from.The top of spring 42 then is provided with a contact 44, and is provided with a switch contact-making surface 46 around this contact 44.When spring is pressed and to be rocked switch 18 and be subjected to rocking, spring 42 rolls, the contact 44 on its top is contacted with switch contact-making surface 46, this moment, power supply was switched at once, but this switch 18 will certainly be connected, once disconnect again, so must cooperate the capacitor among Fig. 2, this capacitor is at the instantaneous electric energy of filling with of power turn-on, enough allow the speech explanation device pronounce several seconds, so as long as fire extinguisher continues to be shaken, promptly can provide enough electric energy to make the automatic sounding of speech explanation device, the emergency operation method of this fire extinguisher is described.

This spring is pressed and is rocked the switch whether switch control sound circuit is switched on, but can not allow this speech explanation device not have sometimes to end most explanation always, so on circuit design, promptly adopt a gauge tap, finish using or in the process of its carrying at fire extinguisher, gauge tap is set in " pass ", avoids it in handling process, constantly to send voice because of rocking; If fire extinguisher is when being in the state of using, gauge tap then is set in " opening ", so that when promptly using, when rocking fire extinguisher, send the method for operating of this fire extinguisher.
