Abstract

A children torch with a sensitive switch comprises a battery and a lamp, which is characterized in further composed of an operation sensor and an electronic switch circuit. The signal output of the operation sensor is connected with the input of the electronic switch circuit which output is connected with the control circuit of lamp. The utility model can avoid mechanical switch to control lamp, but use the operation sensor engaged with the electronic switch circuit to control the lamp. When user takes on the torch, user can avoid searching for the switch and the operation sensor senses operation and outputs trigger signal, and the electronic switch circuit turns on the lamp, with easy application at night and for children application.

Description

Children's flashlight of band inductive switch

Technical field

The utility model relates to a kind of flashlight that belongs to the family expenses small electric apparatus.

Background technology

Flashlight is a kind of tradition and family expenses small electric apparatus commonly used, existing flashlight circuit, generally comprise battery, switch and bulb, control the bright of bulb or go out by a mechanical switch, because switch is less, if children used at midnight, then is not easy to find switch, and the operation of mechanical switch also is not easy, and makes troubles to use.

Summary of the invention

The purpose of this utility model is the children's flashlight that discloses a kind of Convenient switch bulb.

The utility model purpose is to realize like this, it comprises cell apparatus and lamp, it is characterized in that described flashlight also has an action sensor and an electronic switching circuit, the signal output part of action sensor is connected to the input of electronic switching circuit, and the output of electronic switching circuit is connected in the control loop of lamp.

Described action sensor can be: 1, displacement transducer that is installed on the flashlight; Or: 2, touch induction device that is installed in the flashlight surface.

The described touch induction device that is installed in the flashlight surface is made up of two electrodes, and two electrodes are installed in the surface of flashlight at a distance of certain distance.

Flashlight of the present utility model does not need to adopt mechanical switch to come bulb is controlled, but adopt action sensor to cooperate electronic switching circuit to come bulb is controlled, when the operator picks up flashlight, no longer need to seek switch, sense action and output triggering signal by action sensor, light bulb by electronic switching circuit,, be particularly suitable for children and use at night so use more conveniently in the dark.

Description of drawings

Fig. 1 is the circuit theory diagrams of an embodiment of the utility model.

Fig. 2 is the circuit theory diagrams of another embodiment of the utility model.

Fig. 3 is mounted in the scheme of installation of the touch induction device on flashlight surface.

The specific embodiment

Below with reference to the accompanying drawings, embodiments of the invention are described.

Among Fig. 1, action sensor adopts an electronic warning system (as theft-proof alarm of motor vehicle) vibration displacement sensor F commonly used, be installed in flashlight inside, its output is connected to the electronic switching circuit of being made up of Q1 (power field effect pipe D30N3), the output of Q1 is connected on the current supply circuit of lamp L, lamp L adopts white high-brightness LED light emitting diode, power saving and long service life, when flashlight at ordinary times leaves standstill when motionless, displacement transducer F output is a low level, electronic switch Q1 ends, lamp L is not luminous, when the user picks up flashlight, and displacement transducer F output output high level, the Q1 conducting, lamp L lights luminous.Capacitor C 1 and resistance R 1 are attempted by on the input of Q1, both played jamproof effect, play the triggering delay function again: when flashlight in moving process, what displacement transducer F exported is interrupted high level pulse, because the effect that discharges and recharges of capacitor C 1 makes Q1 can keep continuous conducting state.Delay time is by C1 and R1 decision, general desirable 3-5 second.Electronic switching circuit also can be made up of other semiconductor switch device or integrated circuit, as uses common NPN triode 8050 etc.

Among Fig. 2 another embodiment of the present utility model, action sensor adopts a touch induction device, this touch induction device is made up of two touch electrode P1 and P2, and two touch electrodes can adopt the metal electrode or the carbon film electrodes of sheet strip, is installed in the surface of flashlight T, it can be parallel installation, or the installation of thorny torch annular, as Fig. 3, two electrodes are at a distance of certain distance, several centimetres of general desirable 1-, two electrodes are connected the input of electronic switch Q1 by lead-in wire.When flashlight at ordinary times leaves standstill when motionless, resistance between P1 and the P2 approaches infinity, Q1 ends, lamp L is not luminous, and when the user picked up flashlight, finger touched the touch electrode P1 and the P2 on handgrip surface, be equivalent between P1 and P2, insert a resistance less than hundreds of K Ω, make the Q1 conducting, lamp L lights luminous, realizes the purpose of this utility model equally.The effect of C1 and R1 is the same with Fig. 1 embodiment, all be to play effect anti-interference and the triggering time-delay, if choose the numerical value of suitable R 1 and C1, make the voltage at C1 two ends when action sensor moves, be in slow charging and the slow state that discharges, can also make lamp L when switch, have gradually bright function of gradually going out, can lower night unexpected switch bulb to operator's vision and psychology stimulation, be more suitable for using at night in children.
