Description
Technical field
The present invention relates to electronic cigarette technical field, particularly a kind of electronic cigarette anti-oil leakage device and oil-leakage-prevention method.
Background technology
Often there is Leakage in current commercially available electronic cigarette (particularly atomizer), a kind of situation is: leak tobacco tar during suction from suction nozzle end suction nozzle, and this may be that tobacco tar steam-condensation remains in that suction nozzle end is not removed, tobacco tar adding amount is excessive, the oil suction of oil storage parts is uneven or caused by the reason such as atomizer Oil Guide parts Oil Guide excessive velocities; Another kind of situation is: because atomizer central gas flow channel is communicated with ambient atmosphere by air admission hole, also likely causes tobacco tar to leak to electronic cigarette housing exterior walls from air admission hole, stains consumer's hand.Above-mentioned leakage of oil all makes consumer experience sense decline, and brings negative effect to product.Electronic cigarette Leakage not only may aspirate time or improper use time occur, also may electronic cigarette store and transportation in because of vibration, collide and occur.Therefore, solve electronic cigarette Leakage to receive much concern always.

Suction and tobacco tar leak detection can synchronously be carried out, concrete grammar is: during suction, start power switch, trigger light source to open, as without leakage of oil situation, the light of light source transmitting will shine directly on photo-induced reversible deformation layer 5 and make it to bend deformation simultaneously, air admission hole 8 is communicated with venthole 3, external air flow enters atomizer or suction nozzle end from device gas channel, and status indicator lamp turns green, can aspirate; As there is leakage of oil in leaked fuel collection chamber 10, the light that light source is launched can not be irradiated on photo-induced reversible deformation layer 5 by being absorbed by the tobacco tar in leaked fuel collection chamber, photo-induced reversible deformation layer 5 maintains the original state, gas channel is in closed state, external air flow can not enter atomizer or suction nozzle end, status indicator lamp reddens, and can not aspirate, and need clean up oil spill.
Transport and storage process in, the electronic cigarette installing this device additional makes gas channel close because photo-induced reversible deformation layer 5 is in original shape (light source is in closed condition), if tobacco tar seepage, the tobacco tar of seepage can not spill from air admission hole or suction nozzle end, open even if electronic cigarette opens by mistake, as long as there is leakage of oil will be sealed in leaked fuel collection chamber 10 and can not ooze out.
In actual applications, leaked fuel collection chamber 10 volume is enough little.Due to the short and whole leakage oil collection cavity region of radiation of LED light source radiation light path, as long as there is leakage of oil, no matter how electronic cigarette is placed, and radiant light all can be absorbed by leakage of oil completely, and photo-induced reversible deformation layer 5 can Quick-return original state and leaked fuel collection chamber 10 is sealed.(comprising Bending Deformation time and turnaround time) shape-memory material in millisecond scope can be prepared the response time as required.This can play the effect of tobacco tar quick leak-checking and leakproof.
The electronic cigarette anti-oil leakage device of employing photo-induced reversible deformation layer of the present invention can also be utilized to regulate suction air inflow, concrete grammar is: as shown in Figure 3, adopt the electronic cigarette anti-oil leakage device of photo-induced reversible deformation layer to be arranged in shell 12 symmetrically as described in the present invention by two, when needing large air inflow, two light sources can be triggered, under the prerequisite that smokeless oil is leaked, two gas channels in device are all in connected state, air can be entered from two air admission holes, thus produce large air inflow; When only needing little air inflow, alternative one of them light source of triggering, under the prerequisite that smokeless oil is leaked, one of them gas channel in device is in connected state, another gas channel is in closed condition, only enters air from one of them air admission hole, produces less air inflow.
Anti-oil leakage device of the present invention can be arranged between battery rod and atomizer from main separation according to the feature of the quality of atomizer or leakage of oil and to be also mounted between atomizer and suction nozzle end by consumer, or the two is all installed.
Consumer as required, can select the light source needing to open or close.
Clean up oil spill conveniently, liquid retaining block is separated and can cleans up oil spill with device remainder with the light source container cavity 2 having set firmly LED light source 1 as a whole.
