Description
Technical field
The present invention relates to a kind of flashlight, relate in particular to the adjustable flashlight of a kind of light illumination mode.
Background technology
The personnel of operation and explosion-proof operation need to dispose lighting apparatus generally speaking under water, it is the illuminating lamp that is assembled on the waterproof mask that present stage is used more lighting apparatus, this kind illuminating lamp light illumination mode is generally non-adjustable, uses cumbersomely, and cost is also high.The flashlight of the light illumination mode adjusted in the market generally all adopts mechanical knob to realize light-modulating mode operation, the long-time purpose of using the back not reach adjusting because of parts loose contact operation failure, sealing property are bad etc.The more important thing is that when using, undesirable or mechanical switch can produce small electric spark and produce potential safety hazard in operating process because of the water proofing property of mechanical switch structure in some underwater operations and particular surroundings.
Granted publication number discloses a kind of tunable optical flashlight for the Chinese utility model patent of CN201354939Y, this flashlight comprises stack shell, battery, board box, illuminating lamp, lens and movable roll adjustment system, and movable roll adjustment system is in stack shell and between protheca and pedestal.This flashlight changes the distance of collecting lens group by movable roll adjustment system, thereby arbitrarily adjusts focal length, changes the angle and the power of light path, by changing gathering or dispersing of light, can throw light under different situations.This flashlight is regulated illumination by movable roll adjustment system, except still having the above-mentioned shortcoming that the mechanical light modulation structure exists, goes back complex structure.
Summary of the invention
Main purpose of the present invention is, provides a kind of and can conveniently regulate different light illumination modes and flashlight simple in structure.
To achieve these goals, the technical solution used in the present invention is: a kind of flashlight, comprise lamp head, stack shell and light-emitting component, be provided with the circuit board that is connected with light-emitting component in flashlight inside, on the stack shell outside wall surface, be provided with the control piece of strong magnet, circuit board has at least two Hall elements, control piece relatively stack shell move to make strong magnet respectively with the corresponding position of different Hall elements.
The present invention changes the distance of Hall element on strong magnet and the circuit board by mobile control piece, to change the light illumination mode of light-emitting component, the user need not the touch controls circuit can enlarge the convenience and the security reliability of the scope of application of flashlight, the life-span of regulating electric weight prolongation light-emitting component, increase use according to using needs to come the regulated at will light illumination mode.

Fig. 1 is the cutaway view of flashlight of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is that the B-B of Fig. 1 is to sectional view.
Below in conjunction with accompanying drawing the present invention is described in detail.
The specific embodiment
Referring to Fig. 1, flashlight comprises lamp head 1, stack shell and afterbody 3.Light-emitting component 41, reflector 14 and eyeglass 13 are set, the light-emitting component 41 preferred great power LED light emitting diodes that adopt in the lamp head 1.For ease of the installation of inner member, stack shell of the present invention is made of tube body 21 and adapter sleeve 22, and adapter sleeve 22 is arranged between a body 21 and the lamp head 1 and with the two and couples together.Adapter sleeve 22 is provided with projection 53, and projection 53 can be one-body molded with adapter sleeve 22, is installed on the adapter sleeve 22 after also can making separately with rubber or plastic cement elastomeric material again.Control piece 51 is installed on the outside wall surface of adapter sleeve 22 in the outside of adapter sleeve 22.Control piece 51 roughly is tubular, has groove on the inner wall surface thereof, and strong magnet 52 is arranged in this groove.Control piece 51 adapter sleeve 22 rotations relatively, when control piece 51 rotated, strong magnet 52 was with control piece 51 rotations.Referring to Fig. 3, along the circumferential direction evenly be provided with six grooves 512 on the internal face of control piece 51, the shape of groove 512 and protruding 53 tops are suitable, and groove 512 can form with projection 53 and cooperate.
Referring to Fig. 1, circuit board 44 is in adapter sleeve 22, and perpendicular to the axis arranged of flashlight, light-emitting component 41 is by the circuit on the lead 42 connecting circuit plates.Referring to Fig. 2, along the circumferential direction (just flashlight is circumferential) evenly is provided with six Hall elements 431,432,433,434,435 and 436 on circuit board.Core concept of the present invention is, changes the light illumination mode of light-emitting component by the distance that changes strong magnet and Hall element.In the present embodiment, change the distance of strong magnet 52 and each Hall element by rotation control piece 51, can realize when strong magnet 52 is in the position corresponding with Hall element 431,432,433,434,435 and 436 respectively that by setting the light illumination mode of flashlight is respectively flicker, SOS, closes, 100% bright, 50% bright and 25% bright to the selection of Hall element and circuit.Fig. 2 shows flashlight and is in blink states, and strong magnet 52 is in and Hall element 431 corresponding positions.Rotation control piece 51, when projection 53 respectively with control piece 51 on six grooves 512 in one of them when cooperating, strong magnet 52 be in respectively with six Hall elements in one of them corresponding position, the light illumination mode of flashlight is wherein a kind of in above-mentioned six kinds.
Referring to Fig. 1, charging inlet 8 is exposed to the outside of a body 21, is provided with guard ring 7 in the outside of tube body 21, and guard ring 7 is roughly tubular, which is provided with the breach (not shown).Guard ring 7 can be relatively 21 rotations of tube body, when guard ring 7 rotated to the relative position of breach and charging inlet 8, charging inlet 8 was exposed to the flashlight outside, charging inlet can be connected to come to battery 9 and charged with the external charging plug this moment; When guard ring 7 rotated to other positions except that this position, guard ring 7 hid charging inlet 8, and charging inlet 8 and flashlight external isolation are opened.
Referring to Fig. 1, at lamp head 1 respectively and between the head circle 12, control piece 51, adapter sleeve 22, at adapter sleeve 22 respectively and between the control piece 51, tube body 21, guard ring 7, between guard ring 7 and a body 21 and between tube body 21 and afterbody 3, sealing ring 10 is set all.Flashlight of the present invention is provided with high-pressure seal ring 10 between each coupling part, be tightly connected by sealing ring 10, has strengthened the sealing of flashlight, guarantee flashlight under water, high pressure or explosive environment still can normally use.
The foregoing description only is used for the understanding to the present invention's design, is not limitation of the present invention, and design can also have many structural variations to change according to the present invention, and these variations or change all belong to protection scope of the present invention.For example, what at least two Hall elements can be along flashlight is axial arranged, and accordingly, control piece stack shell relatively moves axially, and so also can change the strong magnet on the control piece and the distance of reaction of Hall element by mobile control piece.In addition, guard ring also can be set to relative stack shell and make axially movable structure.
