Description

The electronic cigarette of suction feed flow

Technical field

The present invention relates to a kind of electronic cigarettes of suction feed flow.

Background technique

Electronic cigarette replaces tobacco with the liquid " tobacco tar " of " having taste harmless "；People by suck tobacco tar heater (or electricity Resistance silk) flue gas that generates under high temperature action obtains the feeling of smoking with this.

For structure, electronic cigarette is that the osmosis of " Oil Guide cordage " is utilized to draw the tobacco tar of oil storage cabin mostly at present Enter heater (or directly resistance wire is wound in cordage).This structure has two:

1. the thermal efficiency is low

Flue gas generation needs sufficiently high temperature, and effective section of gasifying should be heater surface.And in above structure Heater surface is closely coupled to it cordage, and the cordage surface that is only adsorbed on finally gasified is contacted with heater Part tobacco tar, and cooling effect is played contained in another part tobacco tar in cordage --- thus drastically influence the thermal efficiency.It is aobvious So this is very big defect for the product being battery powered；

2. being also easy to produce structural leakage

Since cordage and heater connected component are in air intake passage, it is meant that the tobacco tar in cordage is easy to pass through suction Gas channel leaks outward；

Since function, the heater power that tobacco tar infiltration capacity is only cordage line footpath are definite value --- therefore in sucking process Flue gas yield is only directly proportional to the time sucked, unrelated with suction size；In this way when osculum is sucked, excessive flue gas will inhaled It is condensed in gas channel and exists and leak outward in fluid form.Therefore urgently fine using Oil Guide to existing electronic cigarette The mode that dimension rope absorption tobacco tar is heated improves.

Summary of the invention

It is heated and is deposited using Oil Guide cordage absorption tobacco tar present invention aim to address electronic cigarette in the prior art The above problem, a kind of electronic cigarette of suction feed flow is provided.The present invention designs the electronic cigarette of suction feed flow, including shell, storage Bunker, heater, cigarette holder, check valve, heater conducting wire, battery, it is characterised in that: the front end of cigarette holder sets a partition, on partition There are two hole, one is stomata, and stomata one end is connected by shell with atmosphere close to cigarette holder, the other end, another is oilhole, oil By one end of cigarette holder close to heater, the other end is connect by check valve with oil storage cabin in hole, and when smoking, tobacco tar is because of air pressure difference note Enter heater and generates flue gas.Oil storage cabin is the container of thin non-elastic membrane body material production.Oil storage storage capacity subtracts with built-in tobacco tar Reduce less and accordingly.Electronic cigarette is divided into two regions of positive and negative air-pressure by the partition that cigarette holder front end is equipped with.When smoking, tobacco tar is main Because air pressure difference injects heater.Advantages of the present invention has the good thermal efficiency, good tobacco tar feed flow regulation, good antiseepage Leakage, good cost performance.

Detailed description of the invention

Attached drawing 1 is cross-sectional view of the structure of the invention.

Specific embodiment

The electronic cigarette of suction feed flow in figure, including shell 1, oil storage cabin 2, heater 3, cigarette holder 4, heater conducting wire 5, battery 6, it is characterised in that: the front end of cigarette holder sets a partition 7, and a stomata 8 is provided on partition, and stomata passes through shell and big gas phase Even, stomata one end is connected by shell with atmosphere close to the cigarette holder other end；Another is oilhole 10, and oilhole is leaned on by one end of cigarette holder The nearly heater other end is connect by check valve 9 with oil storage cabin 2.Oil storage cabin is the container of thin non-elastic membrane body material production.Cigarette Filter membrane 11 is provided in mouth.Air inlet or air inlet gap (not drawing in figure) are offered on shell.It is provided on supporting plate pneumatic Microswitch (not drawn in figure) control connection heater.

Principle: being in negative pressure in the cigarette holder inner cavity of smoke using suction when sucking electronic cigarette.And it is decomposed into two points Power: a part by stomata supplement fresh air, extraneous fresh air by before the shell of cigarette air inlet or gap entrance, Start the Pneumatic microswitch of heater simultaneously, it can also other controller control fever body runnings；Another part passes through oil Tobacco tar is drawn from oil storage cabin to heater surface and human body is ultimately inhaled by smoke gasification at once in hole.

1. liquid storage (oil storage cabin+check valve)

The container of oil storage cabin system thin non-elastic membrane body material production, a connection check valve, one is then closed；Tobacco tar storage Wherein.Have before factory exclude oil storage cabin, in check valve air operational sequence；Check valve ensure that liquid only export but no import --- because This oil storage cabin is reduced with liquid makees corresponding compression, thus ensure that no matter at electronic cigarette position which kind of direction can obtain it is continual Supply, until tobacco tar is used up；

2. feed flow (cigarette holder inner cavity negative pressure+oilhole)

Under normality, without draught head, therefore tobacco tar will not generate water clock inside and outside oilhole diameter very little and oil storage cabin；

When smoking, the negative role power in cigarette holder inner cavity draws tobacco tar to fever by oilhole, check valve from oil storage cabin Body surface face；

3. (cigarette holder inner cavity negative pressure+heater) occurs for flue gas

When smoking, the electricity of heater is connected while the negative role power in cigarette holder inner cavity supplements fresh air by stomata Source；Heater will be sent to the tobacco tar whole smoke gasification on surface after being powered.

4. aligning (heater+stomata+oilhole)

Greatest requirements according to exhaust gas volumn:

(1) select the maximum supply amount (ML) of tobacco tar: tobacco tar supply amount can be by changing stomata, the realization of oilhole size (example: oilhole is constant, and stomata is bigger, and fuel delivery is smaller).Different with the dynamics of smoking later, tobacco tar supply amount will be in the area 0--ML Between make corresponding change；

(2) select heater electrical power parameter: heater electrical power parameter is then according to the cigarette of unit time maximum supply amount Oil reaches the product for holding voltage, electric current when the whole smoke gasification of heater surface.

5. antiseep (filter membrane)

The micro leakage of tobacco tar be environment temperature significantly change draw have tobacco tar expand with heat and contract with cold and the punching of continuous gravity It hits, tobacco tar is oozed out from oilhole.This patent uses passive protection mode: filter membrane is high oil absorption, ventilative material, at most absorbable 1/4 Oil storage cabin tobacco tar.

The characteristics of this patent:

1. the good thermal efficiency

When smoking, required tobacco tar is quantitatively instilled directly into heater surface and at once whole smoke gasifications, therefore the thermal efficiency is good It is good.It facts have proved that more traditional " Oil Guide cordage " the mode thermal efficiency of this patent improves 1 times or more；

2. good feed flow regulation

Tobacco tar maximum supply amount can be precisely adjusted by adjusting stomata, oilhole size according to tobacco tar viscosity, in this way with suction Food electronic cigarette dynamics, exhaust gas volumn increases and decreases therewith for time increase and decrease --- tobacco tar supply amount increases and decreases in due course ---；

3. good antiseep

When not smoking, since water clock therefore will not be generated without draught head inside and outside oilhole diameter very little and oil storage cabin；When smoking, The tobacco tar overflowed from oil storage cabin is gasified by heater, and little residual is without will form water clock；When meeting judder or Ying Huan The border temperature difference cause oilhole have micro tobacco tar overflow when, by filter membrane absorb without will form water clock；

4. good cost performance

Therefore structure is simple, small in size, manufacturing cost is cheap (without spy without considering special anti-leakage structure by the present invention Kind of material special process), it is convenient for automated production, mating with all kinds of electronic cigarettes (can need to only considers heater conducting wire and battery Connection type), can also have a style of one's own with tobacco tar as consumptive material.
