Description

Electonic incense

Technical field

The present invention relates to electron emitting structure, relate in particular to a kind of Electonic incense.

Background technology

Existing perfume (or spice) of burning incense and pray is generally combustible material to be mixed and suppresses elongated the burning incense forming.But this cigarette that produces in when burning of burning incense is all harmful to human body and atmosphere, and the dust that produces of afterburnt also can be to environment, therefore usually can be prohibited from using because of various fire prevention, environmental regulations.

In prior art, have and adopt Electonic incense to replace the structure that tradition is burnt incense.This kind of Electonic incense conventionally adopts periphery to scribble with the burn incense slender optic fibre of the identical opaque material of color of tradition and makes, the bottom of this optical fiber is used for collecting the divergent rays that light-emitting component sends, light enters into and can be limited in inside of optical fibre transmission after inside of optical fibre and cannot escape from optical fiber perimeter side walls, and final light illuminate the top end of optical fiber with the fragrant head of simulated combustion from the outgoing of optical fiber top while being sent to optical fiber top.But the optical fiber of this kind of Electonic incense structure employing is expensive, thereby cause the cost of manufacture of Electonic incense higher.

Summary of the invention

In view of this, be necessary to provide a kind of lower-cost Electonic incense.

A kind of Electonic incense, comprise for receiving and the light conductor of conducting light, being arranged on the light source of light conductor light inputting end and the light out part of light conductor bright dipping end is set, this light conductor is hollow tube, this light source is LASER Light Source, the contiguous light source setting in one end of this hollow tube and as light inputting end, the other end of this hollow tube is as bright dipping end, and this bright dipping end contacts with light out part and covered by light out part.

Electonic incense provided by the invention adopts LASER Light Source to have the light of high directivity to hollow tube transmitting, thereby provides light harvesting function without being equipped with the divergent rays that expensive optical fiber is conventional light source, makes the manufacturing cost of whole Electonic incense lower.

The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.

The specific embodiment

Referring to Fig. 1, the Electonic incense 10 that first embodiment of the invention provides comprises hollow tube 11, LASER Light Source 12 and light out part 13.

It is elongated cylindric that described hollow tube 11 is substantially.This hollow tube 11 have for the upper end 110 of bright dipping with relative with this upper end, for the lower end 112 of light inlet.In the present embodiment, this hollow tube 11 is external coated coat of colo(u)r 114.Preferably, the color of this coat of colo(u)r 114 and the tradition color of burning incense is identical, the appearance colour of burning incense to simulate tradition.In the present invention, this hollow tube 11 does not do the use that reflects or correct light, therefore hollow tube 11 extremely the coat of colo(u)r 114 on lateral wall all can be made by light transmissive material or light-proof material.

This LASER Light Source 12 is arranged on the lower end 112 of hollow tube 11, to send laser beam in hollow tube 11.In the present embodiment, this LASER Light Source 12 is laser diode 120.This laser diode 120 can or embed hollow tube 11 inside completely from 112 parts, the lower end of hollow tube 11, and in the present embodiment, this laser diode 120 is arranged on 112 places, lower end of hollow tube 11 and does not embed the inside of hollow tube 11.Because laser beam has high directivity, from the laser of laser diode 120 after entering hollow tube 11, upper end 110 that can direct directive hollow tube 11 without any booster action by hollow tube.

This light out part 13 is arranged in the upper end 110 of hollow tube 11 and covers the upper end 110 of hollow tube 11, to receive the laser beam from LASER Light Source 12.This light out part 13 is by light transmissive material, as glass, resin etc. are made.The surface of this light out part 13 is preferably atomization surface, thus the light that arrives light out part 13 can be under the effect of atomization surface be dispersed to each different direction, the perfume (or spice) effect that simulation is burnt incense and lighted.

From theory, this light out part 13 can cover or the local upper end 110 that covers hollow tube 11 completely, because in the thinner situation of laser beam, this light beam may only can be penetrated and the local location of hollow tube 11 upper ends 110, therefore need only and guarantee that the size of this light out part 13 is enough to receive laser beam, and there is no need to make the size of light out part 13 even as big as covering whole upper end 110.In the present embodiment, this light out part 13 covers the upper end 110 of hollow tube 11 completely.

This kind of Electonic incense 10 adopts LASER Light Source 12 to have the laser beam of high directivity to hollow tube 11 transmittings, thereby provides light harvesting function without being equipped with the divergent rays that expensive optical fiber is conventional light source, makes the manufacturing cost of whole Electonic incense 10 lower.

Referring to Fig. 2, the Electonic incense 20 that second embodiment of the invention provides comprises hollow tube 11, LASER Light Source 12 and light out part 13 equally.

It is basic identical that the structure of this Electonic incense 20 is arranged at the Electonic incense 10 of the first embodiment, and difference is: 1. the LASER Light Source 12 of Electonic incense 20 not only comprises laser diode 120, but also comprises diffraction grating 122 and convergent lens 124; 2. Electonic incense 20 comprises multiple hollow tubes 11.

This diffraction grating 122 is arranged in the bright dipping light path of laser diode 120 so that the single beam line from laser diode 120 is separated into multi beam light.In the present embodiment, the just center to diffraction grating 122 of this laser diode 120.Understandable, in actual manufacture process, can design according to real needs the diffraction exponent number of this diffraction grating 122.Determining of diffraction exponent number m can be according to formula: m λ=Λ (n ₂sin θ _dif-n ₁sin θ _inc) calculate, wherein Λ is grating cycle, n ₁for refractive index, the n of incident light place medium ₂refractive index, the θ of diffraction light place medium _incfor incident angle, the θ of incident light _diffor the diffraction angle of diffraction light.

This convergent lens 124 is arranged in the bright dipping light path of this diffraction grating 122 to assemble via the isolated multi beam light of diffraction grating 122, then makes this multi beam light enter respectively different hollow tube 11.In the present embodiment, the center superposition of the focus of this convergent lens 124 and diffraction grating 122, with by the multiple hollow tubes 11 of direction directive to be parallel to each other by the isolated multi beam light of diffraction grating 122, this is arranged parallel to each other described multiple hollow tube 11 becomes possibility, thereby meets the specific demand in Electonic incense use procedure.

It should be noted that, in the present embodiment, the technical scheme of " center superposition of the focus of convergent lens 124 and diffraction grating 122 " is the object in order to realize " multiple hollow tubes 11 can be arranged parallel to each other " and the selection carried out, but, in the time that the multiple hollow tubes 11 of needs are arranged according to other shapes/relative position relation, can corresponding selection convergent lens 124 and diffraction grating 122 between there is other position relationship, to meet other requirements.

In addition, above-mentioned diffraction grating 122, convergent lens 124 are in order to meet respectively light splitting, converging action and to arrange, and this diffraction grating 122, convergent lens 124 also can replace with other beam splitter, light convergent component, do not introduce one by one at this.

Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
