Abstract

The utility model relates to an electric torch, comprising a cylinder body and a luminous body, and two or more luminous bodies are arranged on the head part of the electric torch. The electric torch is characterized in that a mechanical switching push-button is arranged at the tail part of the electric torch; an electronic switch controller comprising a trigger and a driving control circuit is arranged at the front part of the cylinder body. The electric torch has the advantages that the mechanical switch is matched with the corresponding electronic switch controller to realize the switching of the power supply and the alternative work between an LASER and five LEDs. Meanwhile, under the close state of a refractive body, the electronic switch controller is not needed to supply power.

Description

A kind of flashlight

Technical field

The utility model relates to a kind of flashlight, especially relates to the improved flashlight of a kind of switch.

Background technology

At present, the common employing mechanical switch of existing flashlight, the mechanical switch of single-pole single-throw(SPST purposes can only be made the purposes that opens and shuts off of power supply, and can not switch the work of a plurality of loads.But for the flashlight that is provided with two or more illuminators, reach the purpose that several illuminators wheel changes jobs, generally adopt the single pole multiple throw of more complicated and this can make the flashlight structure complexity, increase design difficulty.And the switch of electronic type can switch the work of a plurality of different loads, but electronic switch is owing to must could work under electrifying condition, so can not be as the open and close purposes of power supply, and the consumption of electric power arranged still under the situation that load is closed, produce unnecessary energy resource consumption, the limited energy such as inapplicable use battery are kept the occasion of work, as flashlight etc.

Chinese patent by retrieval, the patent application of relevant flashlight switch has 174, wherein invents 10,162 of utility models, 2 of design patents.

A kind of built-in flashlight switch is disclosed as Chinese patent 02295481.3, form by left and right sides switch base and built-in switch thereof, switch base bottom arranged outside switch, on ﹠ off switch stretches out switch base, it is characterized in that: described switch base top is fluted, places spring in the groove, the spring lower end connects a utmost point of switch, another utmost point is set in the middle of the switch base bottom, and extremely links to each other with another of switch, the switch base outside also has locating hole.

And for example Chinese patent 02288442.4 relates to a kind of improvement of flashlight base push switch, and this device has a flashlight body; Be provided with interior tank in one tail-hood, the rear end is provided with through hole; The button piece of one insulation, its rear end cylinder are that loose joint goes into that tail-hood is screwed into body in the through hole; Its feature is being disk body at the front end of button piece, and this disc surfaces convexes with L type coupler body; One metallic gasket is provided with the perforation of L type for the snapping of L type coupler body and the catch of plural number, and the catch below forms recess; Its base ring body clip of one spring is positioned in the recess.

Result for retrieval shows: do not have to put down in writing the patent application of or close technical scheme identical with the utility model patent application in the Chinese patent.

Summary of the invention

The purpose of this utility model is at the flashlight afterbody mechanical switch to be set to make unlatching or powered-down usefulness, be provided with electronic switch controller at the flashlight body front end, the core of electronic switch controller is a trigger, when power supply is closed by mechanical switch, controller power source is turned off, and (above 30 minutes) trigger can be kept the output level of power cutoff eve in a period of time.Power-on once more in this time period when providing power supply to on-off controller, is given triggering signal of trigger again, makes the upset of trigger output level.The trigger output level is realized laser module (LASER) and five light emitting diodes (LED) wheel are changed jobs by the control box built-in drive circuit.

In a word, adopt a mechanical switch to make electric power starting or close purposes under the situation of not setting up internal wiring in order to solve existing flashlight, be difficult to that flashlight is provided with two or more illuminators and carry out switch control, though and the switch of electronic type can switch the work of a plurality of different loads, but electronic switch is owing to must could work under electrifying condition, and the shortcoming of unnecessary energy resource consumption is still arranged under the situation that load is closed, the utility model provides a kind of new flashlight.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of flashlight, comprise stack shell, tube head, tube tail, illuminator, be provided with two or more illuminators at the flashlight head, illuminator includes but not limited to laser module and light emitting diode, its design feature is: in flashlight tube tail bit a mechanical switch button is set, be provided with on-off controller in the flashlight cylinder front, electronic switch controller comprises trigger and Drive and Control Circuit.

The beneficial effects of the utility model are, a tube position is provided with mechanical switch behind flashlight, is provided with electronic switch controller at the flashlight body front end, and the core of on-off controller is a trigger.Adopt a mechanical switch to cooperate corresponding electronic switch to realize that the switch of power supply and realization change jobs to laser module (LASER) and five light emitting diodes (LED) wheel.Electronic switch controller need not power supply under the situation that refractive body is closed.

Description of drawings

Below in conjunction with accompanying drawing and example the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model ON-OFF control circuit figure.

Among the figure: the 1st, cylindrical shell, the 2nd, shift knob, 3 on-off controllers, E are power supplys, and SW is a mechanical switch, and R is a current-limiting resistance, and LED is a light emitting diode, and LASER is a laser lamp, and RS is a trigger.

The specific embodiment

Referring to Fig. 1, Fig. 2, a kind of flashlight, be provided with five illuminators at flashlight cylinder (1) tube head, illuminator adopts a laser module (LASER) and five light emitting diodes (LED), at flashlight cylinder (1) afterbody a mechanical switch button (2) is set, mechanical switch (2) adopts single-pole single-throw switch (SPST) or other mechanical switch and only makes the single-pole single-throw switch (SPST) purposes, be provided with electronic switch controller (RS) in the flashlight cylinder front, the core of on-off controller is a trigger.Adopt a mechanical switch to cooperate corresponding electronic switch controller to realize that the switch of power supply and realization change jobs to laser module (LASER) and five light emitting diodes (LED) wheel.

The above specific embodiment only is preferred embodiment of the present utility model, and the impartial design variation of being done according to the utility model claim all should be technology of the present utility model and contains such as.
