Abstract
The utility model relates to a novel theft-proof purse with a photosensitive alarming device. The utility model is characterized in that the alarming device is composed of a photosensitive tube, an amplifying triode, a music integrated block, a sounding element, etc., wherein the photosensitive tube is connected with the terminal of a base electrode of the amplifying triode; an emitting electrode of the amplifying triode is directly connected to the music integrated block; the sounding element adopts a piezoelectric ceramic sheet, and the sounding element is connected to the corresponding contact point of the music integrated block; the alarming device is arranged in the surface sandwich of the purse. The utility model has the advantages of simple structure, small size, sensitive response, long service life, difficult damage, little electricity consumption, convenient operation, etc. of the alarming device. The utility model better overcomes the defects in the prior art.
Description
The utility model relates to a kind of dress that is mainly used in and is with small-sized objects such as various certificates, money, ticket tool, and portable small-sized suitcase, specifically refers to a kind of novel anti-theft wallet that has photosensitive warning device.
Wallet is a kind of small-sized object that people often carry; mainly be to be used for loading various certificates; money; small-sized objects such as ticket tool; it is of a great variety; but at present commercially available various wallets all do not attach any antitheft (or anti-lost) warning device is arranged; people are to prevent the stolen of wallet or lose and worried through regular meeting in use; particularly in the many crowded public arenas of people; bring many inconvenience to people; though existing people has carried out big quantity research for this reason; and design the various bags that some have theftproof performance; as adopt infrared alarming; electromagnetic wave is reported to the police or can produce the bag of mode such as high-tension electricity when improper the use; briefcase etc.; though these devices have certain burglar alarm effect; but its volume is generally bigger; structure is comparatively complicated; production cost is also higher; can't directly be applied on the less wallet of volume; lose or stolen and wallet is often easier, thereby people's a kind of wallet with burglar alarm performance that waits in expectation.
The purpose of this utility model just is to provide a kind of novel anti-theft wallet that has photosensitive warning device, with by photosensitive warning device that it was had and the application mode and the structure that do not change existing wallet, in function of use that keeps prior art preferably and advantage, have also that warning device is simple in structure, volume is small and exquisite, be quick on the draw and advantage such as easy to operate, overcome the deficiencies in the prior art preferably.
The purpose of this utility model realizes in the following manner: a kind of novel anti-theft wallet that has photosensitive warning device, mainly form by preceding bag and the warning device that is arranged in the wallet, it is characterized in that above-mentioned warning device is by photosensitive tube, amplifying triode, music-integrating block, sounding component and corresponding contactor and dc source are formed, wherein photosensitive tube adopts photodiode or phototriode, this pipe is bound up on the base terminal of amplifying triode, the emitter stage of amplifying triode directly is bound up on the music-integrating block, above-mentioned sounding component adopts piezoelectric ceramic piece, and be bound up on the corresponding contact of music-integrating block, returning apparatus has contactor on the tie line of dc source, above-mentioned warning device is arranged in the appearance interlayer of wallet, and has aperture corresponding to photosensitive tube and sounding component place on the wallet extexine.
Adopt a kind of novel anti-theft wallet that has photosensitive warning device of the present utility model, because the application mode and the structure that have adopted photosensitive warning device and do not changed existing wallet, make it in function of use that keeps prior art preferably and advantage, have also that warning device is simple in structure, volume is small and exquisite, be quick on the draw, long service life, not fragile, consuming electric power is few and advantage such as easy to operate, has overcome the deficiencies in the prior art preferably.
Description of drawings:
Fig. 1 is a kind of example structure schematic diagram of the present utility model;
Fig. 2 is a circuit diagram of the present utility model.
Wherein: 1-wallet, 2-extexine, 3-warning device, 4-contactor, 5-sounding component, 6-photosensitive tube, 7-amplifying triode, 8-music-integrating block, 9-dc source, 10-aperture.
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, a kind of novel anti-theft wallet that has photosensitive warning device of the present utility model, mainly form by preceding bag 1 and the warning device 3 that is arranged in the wallet, it is characterized in that above-mentioned warning device 3 is by photosensitive tube 6, amplifying triode 7, music-integrating block 8, sounding component 5 and corresponding contactor 4 and dc source 9 are formed, wherein photosensitive tube 6 adopts photodiode or phototriode, this pipe is bound up on the base terminal of amplifying triode 7, the emitter stage of amplifying triode 7 directly is bound up on the music-integrating block 8, above-mentioned sounding component 5 adopts piezoelectric ceramic piece, and be bound up on the corresponding contact of music-integrating block 8, returning apparatus has contactor 4 on the tie line of dc source 9, above-mentioned warning device 3 is arranged in the appearance interlayer of wallet 1, and has aperture 10 corresponding to photosensitive tube 6 and sounding component 5 places on wallet extexine 2.
When wallet takes out in pocket (or other bag) or drops out, make the high sensitivity photosensitive tube contact light source of sensor, its luminous energy transfers the base stage of the voltage of electric energy through amplifying triode to, make its base potential be higher than the emitter stage current potential, amplifying triode is tending towards saturation conduction, supplies with pulse signal of music-integrating block, outputs to sounding component (piezoelectric ceramic piece) after music-integrating block is handled, send alarm sound, the user can cut off the electricity supply by the contactor on the wallet and stop to pipe; In the time of in wallet is in pocket, make amplifying triode be in cut-off state, can not produce alarm call owing to luminous energy is not enough.In use, the user can first power cutoff when taking out wallet, and when putting into, connects power supply again, avoiding unnecessary alarm call, thereby realizes the purpose of this utility model effectively.
