technical field

The invention belongs to the technical field of cigarette substitutes, in particular to a sheet-shaped heating electronic cigarette.

Background technique

According to reports, there are currently nearly 1 billion smokers in the world, and the number of smokers in China exceeds 350 million. These smokers mainly smoke traditional cigarettes. When traditional cigarettes are burned, they undergo volatilization, pyrolysis and high-temperature resynthesis. There are as many as 7,300 compounds in the smoke, of which 2,740 are produced by high-temperature combustion, pyrolysis, and high-temperature resynthesis. These substances Part of it is related to the characteristic aroma of tobacco, but there are also very small amounts of substances that are harmful to the human body (these harmful substances include CO, benzo[α]pyrene, fused-ring aromatic hydrocarbons, etc.).

Recently, due to the continuous upsurge of the anti-smoking campaign and the demand of smokers for their health, the sales of low-tar and low-harm cigarettes have increased, and new tobacco products without combustion process are also booming, especially the growth of electronic cigarettes is particularly rapid. It is predicted that the e-cigarette market will be even bigger in the future.

The electronic cigarettes mentioned in the present invention, also known as electronic nicotine delivery systems (ENDS), belong to the category of new tobacco products. The official definition of an ENDS by the World Health Organization is: A consumer product that delivers nicotine to the lungs.

Electronic cigarettes mainly use batteries to supply power to heating elements such as resistance wires, so that the components such as atomizers, aroma substances and alkaloids in the e-liquid are atomized for consumers to experience. Among them, propylene glycol and glycerol are currently used as the main components of the atomizer, the aroma substances are mainly derived from tobacco extracts and food flavors, and the alkaloids are mainly nicotine.

The core feature of the existing electronic cigarette patents, such as CN201379072, CN102387719A, etc., is that the heating body (filament) is wound on the liquid penetrating part; the liquid storage part stores the smoke oil (also called smoke oil), and the oil guide part stores the oil The oil on the part is led to the liquid penetrating part for the heating body (wire) to heat and atomize.

However, there are still deficiencies in the existing electronic cigarette design, including:

(1) There is a large amount of liquid e-liquid on the liquid storage part, which is easy to cause leakage;

(2) Due to the large amount of liquid added and the long pumping time, the e-liquid is prone to chemical changes in long-term contact with the air, resulting in changes in the taste;

(3) It is not convenient to change the taste;

(4) There is no filter tip for traditional cigarettes when smoking, which is unhygienic and inconvenient, and the teeth cannot be bitten, and the simulation feeling is not good;

(5) The shell of the atomizer is made of metal, and the frequently replaced atomizer not only pollutes the environment, but also wastes resources. Therefore, the existing electronic cigarettes cannot well meet the needs of consumers, and it is urgent to design new electronic cigarettes.

Contents of the invention

The technical problem solved by the present invention is that the existing electronic cigarettes are prone to oil leakage, and the added e-liquid is easily changed when stored in the oil storage cotton for a long time, it is inconvenient to change the taste at any time, and it is unsanitary, inconvenient and lacking There are problems such as poor simulation feeling caused by smoking traditional cigarette filters, and environmental pollution and resource waste caused by the replacement of the metal shell of the atomizer.

In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a sheet-shaped heating electronic cigarette, including an appliance and a cigarette that cooperate with each other and are independent of each other. The appliance includes a housing, a power supply part, a heating part, a clamp There is a detachable connection between the heating part and the housing, and a detachable connection between the clamping part and the heating part or between the clamping part and the housing; the heating part includes a sheet-shaped insertion support and is arranged on A heating element inserted into the surface of the support; the cigarette includes a liquid storage part and a suction nozzle part that penetrate each other, and a cigarette packaging part that seals the liquid storage part and the suction nozzle part together; the liquid storage part stores e-liquid ; The clamping part can accommodate and support the cigarette, and the appliance and the cigarette are matched by inserting the insertion support into the liquid storage part.

By dividing the sheet-shaped heating electronic cigarette into two independent parts, the cigarette stick and the appliance, it is convenient to quickly replace the cigarette stick, and the smoke oil can be sucked and atomized in a short period of time, avoiding the long-term condition of the smoke oil It also reduces the risk of leakage of e-liquid after long-term storage, and it is also convenient to replace e-cigarettes with different flavors at any time. The heating part is detachably connected to the housing, which is convenient for replacing or cleaning the heating part. The clamping part is detachably connected to the housing or the heating part. After the cigarette is sucked, the clamping part can be disassembled, and the cigarette can be pulled out and discarded, so that the heating part and the clamping part can be cleaned. Clean or replace. The detachable connection is a threaded connection or a buckle connection or a plug-in connection. By providing the clamping part, the cigarette can be further clamped, fixed and sealed. By arranging the insertion support in a sheet shape, heating elements can be arranged on one or both sides of the sheet-shaped insertion support, thereby greatly improving heating efficiency. The medium capable of absorbing smoke oil is a multi-layer loose structure, composed of natural fibers (such as tobacco leaves, silk or sheets of tobacco stems, cotton, etc.), ceramic fibers, quartz fibers, glass fibers, carbon fibers, graphite fibers, aramid fibers, Made of at least one of ordinary fiber, paper, cloth or non-woven material. The heating element is one of a heating resistance wire, a conductive heating film, a conductive heating band, and a printed circuit printed on the insertion support. The heating element is preferably a heating resistance wire. If a heating resistance wire is selected, it can be composed of one or more heating resistance wires connected in series or in parallel.

Further, the insertion support is provided with at least one heating element hole passing through the front and rear surfaces of the insertion support, and the heating element passes through the heating element hole. The heating element can be a filamentary heating element. By setting at least one heating element hole, the heating element can pass through the heating element hole, which facilitates the arrangement of the heating element. It is also possible to allow multiple heating elements to pass through the heating element hole at the same time to achieve parallel connection of the heating elements, or to make the same heating element The element passes through the heating hole multiple times to increase the length of the heating element, so that the heating capacity of the heating element can be changed, and the heating efficiency can be improved as required. When the heating element adopts resistance wire, it needs to set the heating element hole; when the heating element adopts printed circuit, it does not need to set the heating element hole; when the heating element uses conductive heating film or conductive heating tape, the heating element hole can be set or not.

Further, heating elements are provided on the front and rear surfaces of the insertion support. Heating elements are arranged on the front and rear surfaces of the insertion support, which can increase the length of the heating elements, and can also realize the series or parallel connection of the heating elements, thereby improving the heating efficiency. The insertion support is made of high temperature resistant insulating hard material. Since the temperature of the heating part is relatively high when heating, and considering that the insertion support needs to be inserted into the liquid storage part, the insertion support is made of a high-temperature-resistant insulating hard material. The high temperature resistant insulating hard material is one of ceramics, glass and polytetrafluoroethylene.

Further, the clamping part is also provided with an extruding structure capable of clamping and extruding the liquid storage part. By setting the extrusion structure, not only can the cigarette stick be clamped, but also when the amount of e-liquid is small, the liquid storage part can be gradually squeezed to continuously atomize the e-liquid.

Further, the appliance is provided with at least one air intake hole. By arranging the air intake holes, it is possible to facilitate the entry of outside air, make the air flow more smooth, and reduce the suction resistance.

Furthermore, the cigarette also includes a transition part arranged between the liquid storage part and the suction nozzle part, and an oil-repelling structure is arranged inside the transition part, and the cigarette packaging part combines the liquid storage part, the transition part and the suction nozzle packaged together. The transition part can not only prevent the e-liquid from the liquid storage part from infiltrating into the mouthpiece, avoid the risk of the e-liquid being directly inhaled into the mouth, but also can cool down the smoke, increase the flavor, adjust the suction resistance, and stretch the smoke. Therefore, at least one structure of a hollow structure or a loose structure is additionally provided behind the oil-repelling structure. The oil blocking structure may adopt a baffle with holes. Because even if the liquid storage part is equipped with an anti-seepage layer, its main function is to prevent the seepage of the outer packaging paper, but it cannot effectively prevent the e-liquid from seeping into the hollow structure or loose structure of the transition part. Setting up an oil-repelling structure, and then connecting a hollow structure or a loose structure can effectively prevent the e-liquid from penetrating into the nozzle.

Further, the nozzle part is made of fiber structure. By setting the fiber filter structure used in traditional cigarettes in the mouthpiece, it avoids the hard feeling of the lips touching the mouthpiece of ordinary e-cigarettes, the peculiar smell or cold feeling of the silicone mouthpiece, and greatly improves the simulation feeling of the e-cigarette. The fiber structure can be made of acetate fiber, propionate fiber or polylactic acid fiber or paper fiber.

Further, a hollow structure and/or a loose structure is also provided in the transition part, and the hollow structure and the loose structure are composed of a fiber structure or a sheet structure. The function of the transition part is mainly to prevent the e-liquid from directly seeping out of the suction nozzle. At the same time, it is also considered that if there is only the liquid storage part and the suction nozzle, the cigarettes will be too short, and the fiber filter structure of the natural extension of the suction nozzle will be damaged. Factors such as insufficient mellowness of the atomized smoke and excessive suction resistance will affect the consumer experience. Therefore, the transition part needs to be added to cool down the smoke, increase the aroma, adjust the suction resistance, and extend the cigarette stick. At least one structure of hollow structure or loose structure. The hollow structure is composed of at least one of natural fibers, plastic fibers, glass fibers, quartz fibers, ceramic fibers, paper fibers, acetate fibers, propionate fibers, polylactic acid fibers, and other artificial fibers. The loose structure is composed of at least one of natural fibers, plastic fibers, glass fibers, quartz fibers, ceramic fibers, paper fibers, acetate fibers, propionate fibers, polylactic acid fibers, and other artificial fibers. The hollow structure and loose structure of the transition part can also be composed of a plastic sheet-like or paper-like sheet-like structure composed of the above-mentioned fibers.

Further, the transition part of the cigarette also includes an aroma-enhancing structure. Setting the flavoring structure can improve the taste of the smoke and enhance the user experience. The fragrance-increasing structure is composed of fragrance substances or fragrance-inducing carriers. The fragrance-increasing structure can be constructed by adding aroma substances to the material forming the transition part, or adding filamentous, sheet-like, or granular aroma-inducing carriers in the transition part.

Further, the liquid storage part includes a medium capable of absorbing e-liquid and the e-liquid absorbed by the medium, and also includes an anti-seepage layer arranged outside the liquid storage part. The anti-seepage layer can be made of tinfoil or anti-seepage paper or anti-seepage film, or it can be made of an anti-seepage cylinder that matches the cigarette and liquid storage medium, has an opening at the contact end with the insertion support of the heating part, and has holes at the other end. The provided anti-seepage layer can not only prevent the e-liquid from penetrating into the packaging part of the cigarette, so as not to affect the appearance of the cigarette, but also prevent the e-liquid from absorbing water or the substances in it volatilize, which is convenient for storage. The e-liquid in the liquid storage part can be liquid, semi-fluid or solid; when it is solid e-liquid, no medium is required.

Compared with the prior art, the beneficial effects of the present invention are mainly reflected in:

(1) By setting the insertion support in a thin sheet shape, not only is it easier to insert the liquid storage part, but also heating elements can be installed on one or both sides of the insertion support, which can greatly improve the atomization ability of the e-liquid;

(2) Cigarettes can be quickly replaced individually, which avoids the oxidative deterioration of the e-liquid and reduces the risk of oil leakage. Once an electronic cigarette of the present invention draws a small amount of smoke, the cigarette can be pulled out from the clamping part and discarded by operating the clamping part, and the new original flavor or new one will be reinstalled in the next round of smoking. Flavored electronic cigarettes can be smoked. Such quick and convenient replacement of electronic cigarettes can complete the suction and atomization of e-liquid in a short period of time, avoiding the oxidation and deterioration of e-liquid under long-term conditions, and also reducing the leakage of e-liquid from conventional e-cigarettes for a long time. risk;

(3) The suction is hygienic and convenient, and the simulation feeling is good. The electronic cigarette of the present invention is composed of two independent parts, a cigarette and an appliance. The transition part of the cigarette prevents the e-liquid from the liquid storage part from penetrating into the fibers of the mouthpiece, avoiding the risk of the e-liquid being directly sucked into the mouth; the mouthpiece has a filter for traditional cigarettes, which prevents the lips from touching ordinary e-cigarettes The hard object feeling of the suction nozzle, the peculiar smell or cool feeling of the silicone nozzle greatly improves the simulation feeling of the electronic cigarette;

(4) It will not cause large pollution and waste of resources to the environment. The electronic cigarette of the present invention uses tipping paper and filter tips similar to traditional cigarettes, and does not use the metal or thick plastic shell of conventional electronic cigarette atomizers, so the cigarettes discarded after smoking will not be atomized like ordinary electronic cigarettes It causes a greater pollution risk to the environment like a device, and also reduces the waste of metal resources.

In a word, the electronic cigarette obtained by the technical solution of the present invention not only has the smoking experience of conventional electronic cigarettes, but also is convenient and hygienic to smoke, simple and economical to manufacture, friendly to the environment, and has broad application prospects.

The fiber filter structure of the mouth 13 will make the atomized smoke not mellow enough, the suction resistance is too large and other factors will affect the consumer experience, so the transition part 12 needs to be added to cool the smoke, increase the aroma, At least one structure of a hollow structure or a loose structure that adjusts the suction resistance, elongates the cigarette, and the like. Wherein, the hollow structure is made of at least one of natural fiber, plastic fiber, glass fiber, quartz fiber, ceramic fiber, paper fiber, acetate fiber, propionate fiber, polylactic acid fiber, and other artificial fibers; the loose structure is made of natural fiber, At least one of plastic fibers, glass fibers, quartz fibers, ceramic fibers, paper fibers, acetate fibers, propionate fibers, polylactic acid fibers, and other artificial fibers. The hollow structure and loose structure of the transition part 12 can also be made of a plastic sheet-like or paper-like sheet-like structure composed of the above-mentioned fibers.

The transition portion 12 of the cigarette 1 also includes an aroma enhancing structure. The aroma-enhancing structure is an aroma substance or an aroma carrier. The fragrance enhancement of the transition part 12 can be realized by adding aroma substances to the materials constituting the transition part 12, or adding fragrance-inducing carriers in the transition part 12 in the form of filaments, flakes, or granules.

The liquid storage portion 11 of the cigarette 1 includes a medium capable of absorbing e-liquid and the e-liquid absorbed by the medium. Described medium is multi-layer loose structure, is made of natural fiber (as silk or sheet of tobacco leaf, tobacco stem, cotton etc.), ceramic fiber, quartz fiber, glass fiber, carbon fiber, graphite fiber, aramid fiber, common fiber, paper, It is made of at least one of cloth or non-woven materials; for example, it is made of embossed paper layers or glass fiber layers. The medium capable of absorbing e-liquid can also adopt a two-layer structure, for example, the inner layer is a layer of glass fibers arranged in layers, and the outer layer is a layer of absorbent cotton wrapped with glass fibers. The anti-seepage layer arranged on the outside of the liquid storage part 11 can be made of tinfoil paper or anti-seepage paper. By tightly wrapping the anti-seepage layer, the effect of preventing the leakage of e-liquid is achieved. The length of the liquid storage part 11 is slightly longer than the length of the effective heating zone of the heating part.

The present invention forms outside air, passes through the air inlet 33 on the shell 3, the concave arc surface on the electrode outer ring 46 and the second side hole 441, the first side hole 451 on the electrode inner ring 45 and the first center. hole 452, the third central through hole 433 on the insulating support 43, the base through the airflow hole 421 inserted into the base 422 of the support 42, the gap between the heating part and the liquid storage part 11, the transition part, and finally the suction The air flow channel of the mouth 13.

When the electronic cigarette of the present invention is used, the casing 3 , the heating part, and the clamping part 5 are connected, and the insertion support 42 is inserted into the liquid storage part 11 . When sucking, the heating circuit is connected through the automatic switch activated by the suction negative pressure or the power switch is manually turned on, and then the suction can be started. If the amount of smoke is small, the squeeze structure 51 can be used to squeeze the liquid storage part 11 in the middle, so that the liquid storage part 11 is in close contact 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, replaced with a new cigarette 1, and a new round of smoking can be performed. At this time, the electronic cigarette gas path is divided into two paths, one path is that the negative pressure generated by the suction passes through the cigarette suction nozzle part 13, the transition part 12, the insertion support part 42 of the heating part and the surface/liquid storage part of the heating element 41 in sequence , the base through the airflow hole 421 on the base 422 of the insertion support 42 of the heating part, the third central through hole 433 on the insulating support 43, and the first central through hole 452 of the electrode inner ring 45, the housing central electrode After the second center through hole 311 of 31 and the inner cavity of the housing, it is transmitted to the power control part 61 at the other end to start it and connect the circuit to heat the heating element 41 of the heating part to atomize the e-liquid in the liquid storage part 11 to generate smoke The other way is that the suction negative pressure passes through the gap between the suction nozzle part 13, the transition part 12, the heating part and the liquid storage part 11, the base on the insertion support 42 base 422 of the heating part through the airflow hole 421, The third central through hole 433 on the insulating support 43, the first central through hole 452 of the electrode inner ring 45, the first side hole 451 on the electrode inner ring 45, the second side on the concave arc surface of the electrode outer ring 46 The hole 441 finally reaches the air intake hole 33 on the housing 3 to make it intake air.

Experiments were carried out using e-liquids with different components by mass:

(1) Add 180 mg of e-liquid containing 83 parts of atomizing agent, 10 parts of tobacco extract, 5 parts of essence, and 2 parts of alkaloid into the liquid storage part 11 of the cigarette, insert it into the heating part of the appliance 2, and lock it The holding part 5 starts suction.

(2) After adding 140 mg of e-liquid containing 88 parts of atomizing agent, 7 parts of tobacco extract, 3 parts of essence and 2 parts of alkaloid into the liquid storage part 11 of the cigarette, insert it into the heating part of the appliance 2 and lock it The holding part 5 starts suction.

(3) Add 160 mg of e-liquid containing 89 parts of atomizing agent, 8 parts of tobacco extract, 2 parts of essence, and 1 part of alkaloid into the liquid storage part 11 of the cigarette, insert it into the heating part of the appliance 2, and lock it The holding part 5 starts suction.

After the above experiments, it shows that the smoke and taste are the same as those of conventional e-cigarettes, but the lip bite is obviously better than that of conventional e-cigarettes. There is no obvious cool or hard feeling on the lips. Significant residue.

At the same time, according to tests, the draw resistance of the electronic cigarette is preferably about 1100 Pa; if the draw resistance is too small or too large, the experience effect of the electronic cigarette will be affected.
