Description

Can discern the burglar alarm wallet of counterfeit money

Technical field

The utility model relates to the personal belongings field, the particularly a kind of burglar alarm wallet that can discern counterfeit money.

Background technology

Wallet majority commonly used at present only has traditional wallet function, promptly deposit cash, ticket etc., but wallet does not all have anti-theft device mostly, causes wallet stolen, does not discern the function of counterfeit money yet, causes many unnecessary loss to the user.Therefore, the antitheft anti-vacation of wallet has just become people's research topic.In recent years, several wallets that have anti-theft device have also appearred, as the wallet of pressure sensor device is housed, patent CN87211239 " the thief-proof anti-mistake warning wallet of press button formula ", the principle theft prevention that adopts pressurized to report to the police, the shortcoming of the antitheft wallet of this kind is that the pressure size is wayward, is easy to generate wrong report or fails to report poor reliability; Also have some light control alarm wallets, as patent CN91218291.1 " light control alarm wallet ", CN91209171.1 " light control alarm wallet ", CN89217458.7 " light-operated loss, burglar alarm wallet " all adopts the principle of optoelectronic induction to carry out controlling alarm, but this kind wallet is subjected to the influence of external environment bigger, especially just can't use evening; The wallet of some tensile force of belt devices for another example, as patent 99247507.4 " pulling force warning wallet ", the wallet of bracelet chain type, as patent CN00134983.X " a kind of antitheft; the warning wallet ", patent CN00207151.7 " music alarm wallet " needs to untie the clip that is fixed on one's body at every turn when using, use up when putting back to and also will press from both sides again, use inconvenience very; Shake control warning wallet in addition, wallet can not leave human body, then reports to the police after leaving, and this kind warning wallet is easy to generate when reporting to the police stolen, or oneself sends to report to the police and think by mistake stolenly, produces unnecessary dispute.For the anti-counterfeit money of wallet, the patent CN02219439.8 that also has only me to design in the present disclosed technology can discern the wallet of counterfeit money, but this patent does not have antitheft function.

Summary of the invention

For fear of with overcome above-mentioned deficiency, the purpose of this utility model provides a kind of burglar alarm wallet that can discern counterfeit money.The realization the technical solution of the utility model is:

By the burglar alarm wallet that can discern counterfeit money that common wallet, power supply, music-integrating block, buzzer, coin identifying light, diac, switch are formed, be main configuration wiring board with the music integrated block IC, in the input connection K switch of music integrated block IC ₁With power supply E, the output of IC connects diac T, and then is connected to the base stage of transistor BG, and the collector and emitter of BG and buzzer Y inductance L constitute output loop, coin identifying light LED and K switch in addition ₂, also constitute an output loop after the power supply E series connection.

The utility model has the advantages that: making is simple, cost is low, function is many, both can be antitheft, can in time discern counterfeit money again, and easy to use, be fit to different time, place and purposes.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model circuit theory diagrams

As shown in the figure, number in the figure is represented respectively: IC. music-integrating block T. diac G. controls contact L. inductance Y. buzzer BG. transistor K ₁. K switch ₂. switch LED. coin identifying light E. power supply.

The specific embodiment

As shown in Figure 1, serve as the wiring board of main configuration with music-integrating block (IC), be connected with switch (K at its input ₁) and power supply (E), the pulse signal of the output output of music-integrating block (IC) can pass through diac (T), pulse signal is delivered to the base stage of transistor (BG), amplify through transistor (BG), colelctor electrode, emitter stage and the buzzer of transistor (BG), inductance (L) constitutes output loop, and the audio alarming signal after the amplification drives buzzer (Y) and sends alarm sound; The control contact (G) of diac (T) links to each other with the electrode that is fixed on around the wallet outer surface; Coin identifying light (LED) and switch (K ₂), power supply (E) series connection constitutes the loop.Its electric principle is: as (K ₁) close, music-integrating block (IC) enters the work holding state, when if the control contact (G) of diac T is subjected to the contact of conductor, when particularly thief's finger touches the electrode that is fixed on around the wallet outer surface, diac T will conducting, the pulse signal that is sent by music-integrating block (IC) just is sent to transistor (BG) and amplifies, and promotes buzzer Y and sends chimes of doom; As switch (K ₂) when closed, coin identifying light (LED) will send the light of purple, carries out the discriminating of coin.

During use, wallet is put in the pocket, when the thief when stealing wallet, will touch the electrode that is fixed on around the wallet outer surface, at this moment wallet just sends chimes of doom, thereby plays antitheft effect; When we when using wallet, wallet taken out opens wallet, switch (K ₁) will close voluntarily, chimes of doom stops; Differentiate coin as need, only need be the switch (K in the wallet lower left corner ₂) open, coin identifying light LED promptly sends purple light, the coin that reflects, and after finishing using, the wallet that closes is put into pocket, (K ₁) close, music-integrating block (IC) enters the work holding state, takes precautions against the thief constantly.

Claims (1)

1, can discern the burglar alarm wallet of counterfeit money, it comprises: power supply (E), music-integrating block (IC), buzzer (Y), diac (T), inductance (L), transistor (BG), coin identifying light (LED) is characterized in that with music-integrating block (IC) serving as main configuration wiring board, at the input connection switch (K of music-integrating block (IC) ₁) and power supply (E), the output of music-integrating block (IC) connects diac (T), and then being connected to the base stage of transistor (BG), the collector and emitter of transistor (BG) and buzzer (Y) inductance (L) constitute output loop, in addition coin identifying light (LED) and switch (K ₂), also constitute an output loop after power supply (E) series connection.
