And cannot be irradiated on photo-induced reversible deformation layer 5, photo-induced reversible deformation layer 5 keeps original state, gas channel to be in closed state, outside
Boundary's air-flow cannot enter atomizer or suction nozzle end, and status indicator lamp reddens, cannot aspirate, need to clean up oil spill.
During transport and storage, the electronic cigarette of the present apparatus is installed additional because photo-induced reversible deformation layer 5 is in original shape (light source
It is closed) and gas channel is made to close, if tobacco tar leaks, the tobacco tar of leakage will not be leaked from air admission hole or suction nozzle end
Go out, opened even if electronic cigarette opens by mistake, as long as there is oil leak that will be sealed in leaked fuel collection chamber 10 without oozing out.
In practical applications, 10 volume of leaked fuel collection chamber is sufficiently small.Since LED light source radiation light path is short and the entire leakage of radiation
Oil collects cavity region, as long as there is oil leak, no matter how electronic cigarette is placed, and radiant light can be absorbed by oil leak completely, photo-induced reversible
Deformation layer 5 can Quick-return original state and so that leaked fuel collection chamber 10 is sealed.Response time (including Bending Deformation can be prepared as needed
Time and turnaround time) in the shape-memory material of millisecond range.This can play the role of tobacco tar quick leak-checking and leakproof.
The electronic cigarette anti-oil leakage device using photo-induced reversible deformation layer of the present invention can also be utilized to adjust draw inlet amount,
Specific method is：As shown in figure 3, two are used as described in the present invention the electronic cigarette anti-oil leakage device of photo-induced reversible deformation layer
It is symmetrically disposed in shell 12, when needing big air inflow, can trigger two light sources, under the premise of smokeless oil leaks,
Two gas channels in device are in connected state, can enter air from two air admission holes, to generate big air inflow；
When only needing small air inflow, alternative triggers one of light source, under the premise of smokeless oil leaks, its in device
In a gas channel be in connected state, another gas channel is closed, only from one of air admission hole enter
Air generates smaller air inflow.
Consumer can select come autonomous by the anti-oil leakage device of the present invention according to the quality of atomizer or the feature of oil leak
It is also mounted between atomizer and suction nozzle end between battery rod and atomizer or the two is all installed.
Consumer can be as needed, and selection needs the light source being turned on and off.
Clean up oil spill conveniently, by the light source accommodating chamber 2 of liquid retaining block and fixed LED light source 1 as a whole with device remaining

A kind of few extinction ingredient, what which can absorb that the light source (1) sends out causes the photo-induced reversible deformation layer (5) to be sent out
The light of raw deformation；After wherein starting the light source (1), what the light source (1) sent out photic makes the photo-induced reversible deformation layer (5)
Overcome the elastic force of elastic layer (6) to be swelled towards the elastic layer (6), thus makes first liquid retaining block (9-1) and the second blocking solution
Block (9-2) is detached from the light side surface of the photo-induced reversible deformation layer (5) and is bonded, and to make the gas channel open, supplies
User aspirates；When electronic cigarette tobacco tar leakage occurs, the electronic cigarette tobacco tar of leakage flows into the gas channel, the extinction
Ingredient blocking illumination is mapped on the photo-induced reversible deformation layer (5), and the original shape of photic deformation layer (5) self-recovery is simultaneously
And the screen resilience of the elastic layer (6) also promotes photic deformation layer (5) to return to the original form, and thus makes first liquid retaining block
(9-1) and the second liquid retaining block (9-2) are bonded again with the light side surface of the photo-induced reversible deformation layer (5), are formed to air-flow
The closure in channel prevents user from aspirating.
5. electronic cigarette oil-leakage-prevention method according to claim 4, which is characterized in that the extinction ingredient is polyalcohols,
It can absorb infrared light, correspondingly, the light source (1) be infrared light supply, the photo-induced reversible deformation layer (5) be it is infrared it is photic can
Inverse deformation layer.
6. electronic cigarette oil-leakage-prevention method according to claim 4, which is characterized in that the extinction ingredient be glycerine or 1,
2- propylene glycol can absorb ultraviolet light, and correspondingly, the light source (1) is ultraviolet source, and the photo-induced reversible deformation layer (5) is
Ultraviolet light induced reversible deformation layer.
7. electronic cigarette oil-leakage-prevention method according to claim 5, which is characterized in that constitute the infrared photo-induced reversible deformation
Layer material be：Polymer composites, the carbon black prepared with carbon nano-tube filled thermoplastic elastomer (TPE) introduces polystyrene
The shape memory polymer composite material of the centering infrared optical response prepared in matrix introduces optical fiber system in polystyrene matrix
Standby mid-infrared light induced shape-memory materials, graphene nanometer sheet are dispersed in the graphite prepared in dimethyl silicone polymer matrix
Alkene/elastic composite.
8. electronic cigarette oil-leakage-prevention method according to claim 6, which is characterized in that constitute the ultraviolet light induced reversible deformation
Layer material be：In acrylic acid esters co-polymer network introduce cinnamate group monomer prepare ultraviolet light induced shape-changing material or
The liquid crystal elastic body for using the azobenzene of photic cis-trans isomerism to be prepared as mesomorphic unit.
