Description

Portable automatic explosive drug detecting instrument

Technical field

The present invention relates to detector, particularly a kind of Portable automatic explosive drug detecting instrument.

Background technology

Along with social development and civilized progress, the requirement that people control for public safety and drugs is increased day by day.There have been some similar equipment public place now, but detection time is long, reuses needed clearance time also long, has greatly affected actual testing.So, all very large for social demand and the market demand of cost compare portable explosive Drugs Checkout Gear low, convenient to use.

U.S. Si Baike company (Spectrex) provides a kind of detector (model is EX-DETECT XD-2) that utilizes chemical reagent explosive detection and drugs, but owing to must manually adding reagent, operate more inconveniently, the popularization of product is affected.

Summary of the invention

Technical matters to be solved by this invention is to provide a kind of Portable automatic explosive drug detecting instrument, its compact conformation, use quick, easy to carry.

For solveing the technical problem, the invention provides a kind of Portable automatic explosive drug detecting instrument, it is characterized in that, it comprises base, the button of carrier state pilot lamp, circuit board, heating arrangement, test paper fixture, stepper motor, screw mandrel, reagent piston, reagent container, reagent dropper, guidance panel, test tube is changed cover plate, promote bolt, button is through guidance panel, circuit board is between button and base, test tube is changed cover plate and is covered stepper motor and reagent container, stepper motor is directly screwed into an integral body with screw mandrel, screw mandrel is connected with screw thread with promotion bolt, promoting bolt contacts in buckle mode with reagent piston, reagent piston contacts with reagent container inwall in the middle of reagent container, the liquid inlet of reagent dropper is positioned at the centre position, bottom surface of reagent container, the liquid outlet of reagent dropper is positioned at directly over heating arrangement, heating arrangement is in the centre of test paper fixture.

Preferably, described Portable automatic explosive drug detecting instrument also comprises power interface and power switch, and power interface and power switch are positioned in a side of base.

Preferably, described Portable automatic explosive drug detecting instrument also comprises a upper cover plate, and upper cover plate and base coordinate closes Portable automatic explosive drug detecting instrument.

Preferably, described heating arrangement is that the impedance that FPC coil plate is made is the heater coil of 1 ohm of left and right, and coil two ends are accessed by 12V power supply, a heat conduction alloy sheet in addition above coil plate.

Positive progressive effect of the present invention is: the present invention is in the situation that guaranteeing accuracy of detection, explosive illicit drugs inspection volume and weight have greatly been dwindled, can hang on waistband completely or take, simultaneously, there is automatic liquid supply device and automatic heating device and can make operation more convenient, in addition, be also furnished with large capacity rechargeable battery, can independently use in the wild, also can directly on automobile, charge or charge with power supply adaptor.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Fig. 2 is the structural representation that in Fig. 1, test tube is changed cover plate bottom.

Embodiment

Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the present invention that intactly illustrates.

As depicted in figs. 1 and 2, Portable automatic explosive drug detecting instrument of the present invention comprises following element: the button 2 of base 1, carrier state pilot lamp, circuit board 3, heating arrangement 4, test paper fixture 5, stepper motor 6, screw mandrel 7, reagent piston 8, reagent container 9, reagent dropper 10, upper cover plate 11, guidance panel 12, power interface 13, power switch 14, test tube change cover plate 15, with screw mandrel 7 with the connected promotion bolt 16 of screw thread; Power interface 13 and power switch 14 are positioned in a side of base 1, button 2 is through guidance panel 12, circuit board 3 is between button 2 and base 1, test tube is changed cover plate 15 and is covered stepper motor 6 and reagent container 9, upper cover plate 11 can be closed whole Portable automatic explosive drug detecting instrument with base 1, when using Portable automatic explosive drug detecting instrument, only need to open upper cover plate 11.

Stepper motor 6 is directly screwed into an integral body with screw mandrel 7, and screw mandrel 7 is connected with screw thread with promotion bolt 16, promotes bolt 16 and contacts in buckle mode with reagent piston 8, and reagent piston 8 contacts with reagent container inwall in the middle of reagent container 9.The liquid inlet of reagent dropper 10 is positioned at the centre position, bottom surface of reagent container 9, and liquid outlet is positioned at directly over heating arrangement 4.Heating arrangement 4 just in time exposes whole heating arrangement 4 at centre and the test paper fixture 5 of test paper fixture 5.The motor, screw mandrel, promotion bolt, test tube, the reagent dropper device that promote reagent can have many covers, and this example has the duplicate reagent adding set of two covers, for adding two kinds of different reagent.Heating arrangement is that the impedance that FPC coil plate is made is the heater coil of 1 ohm of left and right, coil two ends are accessed by 12V power supply, a heat conduction alloy sheet in addition above coil plate, test paper is placed on conducting strip like this, and heater coil is switched on and can be heated to 100 degrees Celsius 3 seconds.

The principle of work of Portable automatic explosive drug detecting instrument of the present invention is as follows: be first possible containing the test paper of Poison or explosive Related Component, be placed on trial-production fixture the inside, then press left side button, No. one stepper motor rotarily drives screw mandrel rotation, cause promoting the reagent piston advances forward that bolt advances in promotion reagent container, extruding a reagent adds on test paper by reagent dropper, then heating plate meeting heatable catalytic chemical reaction, shows corresponding color according to the corresponding composition in test paper.If press the right button, No. two stepper motors rotarily drive screw mandrel rotation, cause promoting the piston advances forward that bolt advances in promotion reagent container, extruding No. two reagent adds on test paper by reagent dropper, the chemical reaction of No. two reagent is without heatable catalytic, so now heating arrangement is not worked, therefore can directly watch test paper color to analyze Related Component information in trial-production.

In order to facilitate inoperative place to use, this Portable automatic explosive drug detecting instrument also comprises the chargeable high-capacity lithium battery that voltage is 12V.

Portable automatic explosive drug detecting instrument of the present invention is a kind of realization by the device of chemical reaction color developing detection explosive and illicit drugs inspection, and main application electric technology and structure technology are embodied as chemical reaction provides condition.

Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, do not deviating under the prerequisite of principle of the present invention and essence, can make various changes or modifications to these embodiments.Therefore, protection scope of the present invention is limited by appended claims.
