Abstract

The utility model relates to an electronic remote control theft-proof bag which can give an alarm, can electrically shock a target and can resist theft. A common bag is additionally provided with an induction circuit, a control circuit, an emitting and alarm circuit, a high-voltage generating circuit and a high-voltage electrode. A remote sensing/control device is carried by a host of the bag. A precaution switch in the bag is turned on, and a switch of the remote sensing/control device is positioned at a 'receiving' position. After a thief is close to the bag for a period of time, an alarm emits a sound, which warns the thief. Simultaneously, a control signal is emitted. The remote sensing/control device emits a sound. The alarm sound of the bag is lasted for some time. When the thief stops committing a crime, the alarm sound disappears. When the thief continues to commit a crime, the bag releases high voltage, which forces the thief to stop committing a crime. The utility model has the advantages of sensitive response, and convenient and reliable usage.

Description

Electronic remote control theft-proof case or bag

The utility model relates to the antitheft case and bag of a kind of electronic telecontrol.

Antitheft case and bag of Chu Shouing in the market, just sound is alert antitheft, and switch can not remote control, and function falls behind.Some case and bag has electric shock device, but insufficiency has used certain difficulty, and automaticity is low.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of warning is provided, the anti-case and bag of stealing, and it is sensitivity, warning reliably very, even discharges little high pressure, can stop case and bag stolen effectively, simultaneously health is not had injury.

The purpose of this utility model realizes by following proposal:

In various case and bag in the market, increase induction, control, emission is reported to the police, high-pressure generating circuit and high-field electrode, return the case and bag owner and increase remote sensing/control device of carrying, when using anti-theft feature, open early warning switch in the case and bag, remote sensing/control device switch places " receipts " position, when the thief near case and bag after a period of time, alarm sounding warning thief in the case and bag, the while emissioning controling signal, remote sensing/control device sounding that effect case and bag owner carries, the case and bag chimes of doom continues for some time, and stops crime as the thief, and chimes of doom disappears, the thief continues crime, remote sensing/control device switch is still located " receipts " position, and case and bag discharge high voltage forces the thief to stop crime, reaches the antitheft purpose of alarm." send out " position as remote sensing/control device switch place, remote sensing/control device sends control signal control high-pressure generating circuit, makes high-pressure generating circuit stop to discharge high pressure.

Compared with prior art, the utlity model has following advantage:

1, adopts little high-voltage pulse, can effectively instead steal, human body is not had any injury;

2, have the people can inform owner near behind the case and bag certain hour, owner is is in time gone and found out what's going on, it is antitheft whether decision shocks by electricity to it;

3, adopt the boxlike inductive pick-up, be quick on the draw, use reliable;

4, remote sensing/control device can be controlled the discharge of case and bag easily;

5, simple in structure, little power consumption, in light weight, easy for installation, can stop case and bag stolen effectively.
