Wherein, the components of the atomizing agent mainly adopt propylene glycol and glycerol at present, the fragrant substances mainly come from tobacco extracts and edible essences, and the alkaloid mainly is nicotine.

The core features of existing electronic cigarette patents, such as CN201379072, CN102387719A, etc., are that a heating body (filament) is wound on a liquid permeable member; the liquid storage part stores tobacco tar (also called tobacco tar), and the oil guiding part guides the oil on the oil storage part to the liquid penetration part for heating and atomizing the heating body (filament).

However, the existing electronic cigarette design has shortcomings, including:

(1) a large amount of liquid tobacco tar exists on the liquid storage part, so that leakage is easy to cause;

(2) because of more liquid adding and long pumping time, the tobacco tar is easy to generate chemical change due to long-term contact with the air, so that the taste is also easy to change;

(3) the taste cannot be changed conveniently;

(4) the cigarette is not provided with a filter tip with a traditional cigarette during smoking, is not sanitary and inconvenient, can not be bitten by teeth and has poor simulation feeling;

(5) the atomizer shell is made of metal, and the atomizer which is frequently replaced not only pollutes the environment, but also wastes resources. Therefore, the existing electronic cigarette cannot well meet the requirements of consumers, and a new electronic cigarette is urgently needed to be designed.

The impermeable layer arranged outside the liquid storage part 11 can be made of tin foil paper or impermeable paper, and the impermeable layer is tightly wrapped to achieve the effect of preventing the tobacco tar from permeating outwards. The length of the liquid storage part 11 is slightly longer than the effective heating area length of the heating part.

The invention forms the air flow channel from the outside air, the air inlet 33 on the shell 3, the concave arc surface and the second side hole 441 on the outer ring of the electrode, the first side hole 451 and the first center through hole 452 on the inner ring 45 of the electrode, the third center through hole 433 on the insulating support piece 43, the gap between the heating part and the liquid storage part 11, and finally to the suction nozzle part 13.

When the electronic cigarette of the present invention is used, the housing 3, the heating unit, and the holding unit 5 are connected, and the insertion holder 42 is inserted into the liquid storage unit 11. When in suction, the heating circuit is communicated by an automatic switch started by suction negative pressure or a power switch is manually turned on, and then suction can be carried out. If the amount of smoke is small, the pressing structure 51 can be used to press the liquid storage part 11 toward the middle, so that the liquid storage part 11 is tightly contacted with the heating element 41, and the oil on the outer layer of the liquid storage part 11 moves toward the heating element 41. After the smoking is finished, the cigarette 1 can be taken out, and a new round of smoking can be carried out by replacing the cigarette 1 with a new cigarette 1. The electronic cigarette gas circuit is divided into two paths, wherein one path is that negative pressure generated by suction passes through the cigarette mouthpiece part 13, the transition part 12, a gap between the heating part and the liquid storage part 11, the third center through hole 433 on the insulating support part 43, the first center through hole 452 of the electrode inner ring 45, the second center through hole 311 of the shell center electrode 31 and the inner cavity of the shell in sequence, and then is transmitted to the power supply control part 61 at the other end to start the electronic cigarette gas circuit and is connected with the circuit to heat the heating element 41 of the heating part so as to atomize the tobacco tar in the liquid storage part 11 to generate smoke; the other path is that the suction negative pressure passes through the nozzle part 13, the transition part 12, the gap between the heating part and the liquid storage part 11, the third center through hole 433 on the insulating support 43, the first center through hole 452 of the electrode inner ring 45, the first side hole 451 on the electrode inner ring 45, the second side hole 441 on the concave cambered surface of the electrode outer ring 46 in sequence, and finally enters the air inlet hole 33 on the shell 3 to make air inlet.

The experiments were carried out with tobacco tar having different mass parts composition:

(1) adding 180 mg of tobacco tar containing 86 parts of atomizing agent, 8 parts of tobacco extract, 5 parts of essence and 1 part of alkaloid into the liquid storage part 11 of the cigarette, inserting the liquid storage part into the heating part of the appliance 2, locking the clamping part 5 and starting smoking.

(2) 200 mg of tobacco tar containing 90 parts of atomizing agent, 6 parts of tobacco extract, 2 parts of essence and 2 parts of alkaloid is added into a cigarette liquid storage part 11, then the cigarette liquid storage part is inserted into a heating part of an appliance 2, and a clamping part 5 is locked to start smoking.

(3) Adding 160 mg of tobacco tar containing 88 parts of atomizing agent, 6 parts of tobacco extract, 4 parts of essence and 2 parts of alkaloid into the liquid storage part 11 of the cigarette, inserting the liquid storage part into the heating part of the appliance 2, locking the clamping part 5 and starting smoking.

The experiments show that the smoke and the taste are the same as those of the conventional electronic cigarette during smoking, but the lip biting feeling is obviously better than that of the conventional electronic cigarette, the lips do not have obvious cooling feeling and hard object feeling, the smoking is easy, the use is convenient and sanitary, and no obvious residue exists in a heating part.

Meanwhile, the test shows that the suction resistance of the electronic cigarette during smoking is about 1100 Pa; if the suction resistance is too small or too large, the experience effect of the electronic cigarette is affected.

The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should be covered by the present patent.
