Abstract
The utility model discloses a paper metal detector who makes by hand, including handle and ring form, the handle is hollow structure, internally mounted has the circuit board base of circuit board and the battery case that is provided with the battery in the handle, be provided with power indicator on the front of handle and survey the pilot lamp, be provided with turn button on the side of handle, power indicator, it is connected with battery and circuit board respectively to survey pilot lamp and turn button, the circuit board is connected with the buzzer through the connecting wire, be provided with the coil in the ring form, the coil is connected through the wire with the circuit board, handle and ring form block are connected, and the block junction is still fixed through the double faced adhesive tape. The utility model discloses the structure is simpler, is favorable to the student to pass through to make personally metal detector, its convenient to detach and installation, and the product structure is open, but the spare part split, the user can clearly see each partial structure to understand corresponding natural science principle.
Description
Technical field
It is manual that the utility model relates to a kind of new technology paper, particularly relates to a kind of home built papery metal detector.
Background technology
Metal detector is mainly used for the electronic device detecting metal, can be applicable to multiple field.Militarily, metal detector can be used for detecting metallic mine; In security fields, the weapon and tool used in crime carried with or hide can be detected; In archaeology, the ancient tomb of burying metal can be detected, find gold, silver, treasures and jewels in ancient tomb and jewellery or other metallic articles; In engineering, can be used for Underground metal embedded object, such as pipeline, pipeline etc.; In ore prospecting, can be used to detect and find rusty gold particle; Industrial, can be used for on-line monitoring, as removed cotton, coal, the metal sundries etc. in food.Metal detector also can be used as the apparatus carrying out teenager's defence education and activity to popularize scientific knowledge, also to can yet be regarded as interesting games for play, but existing metal detector manufacture difficulty is large, be not easy to dismounting and install, thus be not easy to the study of student and grasp metal detector, be more not easy to the propagation and employment of metal detector.
Utility model content
For deficiency of the prior art, the utility model provides a kind of easy for removal and installation, is also convenient to the study of student and the metal detector of grasp.
To achieve these goals, technical solution adopted in the utility model is:
A kind of home built papery metal detector, comprise handle and annular solid, handle is hollow structure, in handle, inside is provided with the circuit board base of circuit board and is provided with the battery case of battery, the front of handle is provided with power light and detection pilot lamp, the side of handle is provided with rotary knob, power light, detection pilot lamp is connected with battery and circuit board respectively with rotary knob, circuit board is connected with hummer by connecting line, coil is provided with in annular solid, coil is connected by wire with circuit board, handle and annular solid are connected together, and the place of being connected together also is fixed by double faced adhesive tape.
Described battery is the square dry cell of 9V.
Described handle and annular solid are all form by paper is folding.
The beneficial effects of the utility model: compared with prior art, the utility model structure is simpler, be conducive to student by personally making metal detector, thus be also conducive to the principle of work that student grasps metal detector more, it is easy for removal and installation, user can be known and see its structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model circuit board shows and the schematic diagram that hummer, coil are connected;
Fig. 3 is principle of work schematic diagram of the present utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of home built papery metal detector, comprise handle 1 and annular solid 2, handle 1 is hollow structure, in handle 1, inside is provided with the circuit board base of circuit board and is provided with the battery case of battery, the front of handle 1 is provided with power light 11 and detection pilot lamp 12, the side of handle 1 is provided with rotary knob 13, power light 11, detection pilot lamp 12 is connected with battery and circuit board respectively with rotary knob 13, circuit board is connected with hummer 14 by connecting line, coil 21 is provided with in annular solid 2, coil 21 is connected by wire with circuit board, handle 1 and annular solid 2 are connected together, and the place of being connected together also is fixed by double faced adhesive tape, described battery is the square dry cell of 9V, described handle 1 and annular solid 2 are all form by paper is folding.
As shown in Figure 3, annular solid 2 of the present utility model is when object, because the coil 21 in annular solid 2 passes through electric current, thus produce magnetic field A, when coil 21 is more and more near object, magnetic field A will produce vortex flow, and produce another magnetic field B simultaneously, and magnetic field B can have an impact to magnetic field A, therefore metal detector can determine whether to there is metal according to the change in magnetic field, will run hummer 14 and detection pilot lamp 12 when detection has metal.
The beneficial effects of the utility model: compared with prior art, the utility model structure is simpler, be conducive to student by personally making metal detector, thus be also conducive to the principle of work that student grasps metal detector more, it is easy for removal and installation, user can be known and see its structure.
