TECHNICAL FIELD

[0001] The utility model relates to electronic cigarette technical field, concretely relates to a kind of electronic cigarette cartridge. BACKGROUND

[0002] The existing baking type electronic cigarette roasting apparatus, in order to avoid the cigarette to produce a large number of harmful substances and can enjoy the unique taste of cigarette, can roast the tobacco of the cartridge, and the tobacco is heated without burning, that is, it is roasted below the combustible temperature until it smokes, and the user can inhale the cigarette smoke. Because the tobacco product is smoked by heating instead of open fire burning, the user inhales a large number of harmful substances produced by open fire burning of tobacco products, so smoking with electronic roasting apparatus is gradually widely used.

[0003] For the electronic cigarette cartridge, the authorized announcement number CN114009829B discloses an electronic cigarette cartridge, which specifically discloses that it is composed of a flow guiding section, a smoking base material section, a hollow section, and a filter section arranged in the wrapping member in turn; the wrapping member is a hollow paper cylinder; the flow guiding section is arranged at the far end of the wrapping member, and the flow guiding section is surrounded by the inner cylinder wall of the wrapping member and the first partition member; the first partition member is attached or glued in the inner cylinder wall of the wrapping member and separates the flow guiding section and the smoking base material section; the smoking base material section is filled with a smoking base material and a sensing body, the smoking base material is a particle made of tobacco and / or non-tobacco plants; the sensing body is made of continuous sheet-shaped or columnar magnetic conductive material after at least one bending or bending, and the longitudinal section of the sensing body presents an incomplete closed geometric shape in the cigarette; the sensing body has one end and two legs; the end in the closed state on the sensing body is the end, and the two sides in the open state are the legs; the ends of the two legs are arranged towards the first partition member, and the end is arranged towards the second partition member; the sensing body is placed in the smoking base material and surrounded by the smoking base material; the hollow section is surrounded by the second partition member, the inner cylinder wall of the wrapping member, and the filter section, the second partition member is attached or glued on the inner cylinder wall of the wrapping member and separates the hollow section and the smoking base material section; the filter section is arranged at the near end of the wrapping member, and the filter section is made of a material capable of filtering and cooling smoke; the first partition member and the second partition member are both flexible sheets, and the longitudinal sections of the two are both “]” shaped or “[” shaped. The first partition member and the second partition member both include an inner ring seal portion and an outer ring fitting portion, the inner ring seal portion and the outer ring fitting portion are different components of a whole flexible sheet, the inner ring seal portion is the center part of the whole flexible sheet and is circular, the diameter of the inner ring seal portion = the inner cylinder diameter of the wrapping member; the outer ring fitting portion is the other part of the whole flexible sheet except the inner ring seal portion; the flexible sheet is one of 3000CU-20000CU high-transparency formed paper, punched paper, punched aluminum foil, punched aluminum foil paper, punched silica gel sheet, punched gel sheet, and punched polylactic acid sheet.

[0004] However, for the above electronic cigarette cartridge, there is still room for improvement, for example: although the induction body is arranged in the smoking base material and surrounded by the smoking base material, the arrangement structure of the induction body is not good enough, so that the induction body is not good enough for the baking effect of the smoking base material. In addition, although the cartridge is provided with a first partition member in the cylinder wall of the wrapping member, the first partition member is made of one of high-transparency molding paper, punched paper, punched aluminum foil, punched aluminum foil paper, punched silica gel sheet, punched gel sheet, and punched polylactic acid sheet, so that the design of the first partition member cannot be used to filter the air before entering the smoking base material, so that the use effect is not good enough; at the same time, the first partition part cannot be used to block the ash formed by the baked smoking base material, that is, the leakage prevention effect is not good.

[0005] Therefore, it is necessary to improve the prior art. Invention content

[0006] In view of the problems existing in the prior art, the purpose of the present application is to provide an electronic cigarette cartridge, which sets the induction ring in a ring shape and extends its upper and lower ends to the upper and lower end faces of the tobacco section, so that the baking effect is more uniform, and the tobacco can be more fully baked. In addition, a head solid core filter rod is arranged at the head of the cartridge, so that the air before entering the tobacco section can be filtered, so that the user can inhale cleaner smoke when smoking. Moreover, the head solid core filter rod can also block the ash formed by the baked tobacco very well, avoiding ash leakage, that is, the leakage prevention effect is good.

[0007] In order to achieve the above purpose, the technical scheme of the present application is:

[0008] An electronic cigarette cartridge comprises a wrapping paper cylinder and a head solid core filter rod, a tobacco section, a hollow filter rod and a tail solid core filter rod arranged in the wrapping paper cylinder from top to bottom; an induction ring is arranged in the tobacco section and coaxial with the wrapping paper cylinder; the upper and lower ends of the induction ring penetrate the upper and lower end faces of the tobacco section, so that the length of the induction ring is equal to the length of the tobacco section; the inner and outer wall surfaces of the induction ring are surrounded by the tobacco in the tobacco section; the head solid core filter rod, the hollow filter rod and the tail solid core filter rod are made of acetate fiber; the induction ring can be used to bake the tobacco in the tobacco section more fully; the head solid core filter rod can be used to improve the filtering effect of the cartridge, to prevent misfire and to block ash.

[0009] Further comprising the following technical schemes:

[0010] Further, a plurality of through holes are evenly distributed on the side wall of the induction coil, which can improve the efficiency of baking to some extent.

[0011] Further, the shortest distance between the outer wall of the induction coil and the wrapping paper tube is equal to the distance between the inner wall of the induction coil and the central axis of the wrapping paper tube, so that the induction coil can bake the tobacco in the tobacco segment more uniformly, thereby improving the efficiency of baking.

[0012] Further, the hollow filter rod is provided with a first aerosol channel and a second aerosol channel connected in sequence from top to bottom, the upper end of the first aerosol channel is communicated to the tobacco segment, and the lower end of the second aerosol channel is communicated to the tail solid core filter rod. Through the above arrangement, the user can ensure that the smoke does not have a hot mouth feeling.

[0013] Further, the diameter of the first aerosol channel is smaller than that of the second aerosol channel, so that the cooling effect of the smoke can be improved to some extent.

[0014] Further, the induction coil is arranged in the upper end port of the first aerosol channel, so that the smoke can be more smoothly input into the first aerosol channel 41.

[0015] Further, the induction coil is made of a material capable of converting electromagnetic energy into heat.

[0016] Further, the induction coil is made of a material capable of converting electromagnetic energy into heat.

[0017] Further, the length of the head solid core filter rod is 5mm, the length of the tobacco segment and the induction coil is 11mm, the length of the hollow filter rod is 17mm, and the length of the tail solid core filter rod is 11mm.

[0018] Further, the material of the head solid core filter rod, the hollow filter rod and the tail solid core filter rod can also use nicotine molecule branding polymer instead of acetic acid fiber.

[0019] The beneficial effects of the present application are:

[0020] The induction coil is arranged in the upper end port of the first aerosol channel, so that the smoke can be more smoothly input into the first aerosol channel 41.

[0021] Furthermore, the solid filter at the head also employs a solid filter design, allowing it to filter the air before it enters the tobacco section, thus providing users with cleaner smoke. Moreover, because the solid filter at the head seals off the tobacco section, it serves as an indicator. Specifically, this design prevents some users from mistakenly lighting the cartridge as a regular cigarette. Since the user cannot directly see the tobacco section, it serves as a reminder that the cartridge is not a regular cigarette without a sensor coil, preventing accidental ignition by directly lighting the solid filter at the head. Simultaneously, the solid filter at the head effectively blocks the ash formed from the toasted tobacco, preventing leakage and providing excellent leak-proof performance.

[0030] The specific implementation methods according to this disclosure are described below with reference to the accompanying drawings.

[0031] like Figures 1-5As shown, an electronic cigarette cartridge comprises a wrapping paper tube 1, a head solid core filter stick 2, a tobacco segment 3, a hollow filter stick 4 and a tail solid core filter stick 5 which are sequentially arranged in the wrapping paper tube 1 from top to bottom; an induction ring 6 is arranged in the tobacco segment 3 and coaxial with the wrapping paper tube 1; the upper and lower ends of the induction ring 6 respectively penetrate the upper and lower end faces of the tobacco segment 3 so that the length of the induction ring 6 is equal to the length of the tobacco segment 3; the inner and outer wall surfaces of the induction ring 6 are both surrounded by the tobacco in the tobacco segment 3; the head solid core filter stick 2, the hollow filter stick 4 and the tail solid core filter stick 5 are all made of acetate fiber. Specifically, the induction ring 6 can be used to make the tobacco in the tobacco segment 3 be more fully roasted; the head solid core filter stick 2 can be used to improve the filtering effect of the cartridge, to play a role in preventing mistaken ignition and to block ash.

[0032] In summary, the induction ring 6 is arranged in a ring shape and its upper and lower ends respectively extend to the upper and lower end faces of the tobacco segment 3, so that it can roast the tobacco around it in a ring shape during heating. This roasting structure has a large roasting area and more uniform roasting effect, so that the tobacco can be more fully roasted. In addition, since the head solid core filter stick 2 is also designed as a solid core filter stick, it can filter the air before entering the tobacco segment, so that the user can inhale cleaner smoke when smoking. Moreover, since the head solid core filter stick 2 seals the tobacco segment 3, it can be used as an identifier. Specifically, this design can prevent some users from mistakenly igniting the cartridge as a common cigarette without knowing the situation, i.e. this design makes the user cannot directly see the tobacco in the tobacco segment 3, so that it can remind the user that this cartridge is not a common cigarette without an induction ring under certain circumstances, so that the user cannot directly ignite the position of the head solid core filter stick 2, i.e. to prevent mistaken ignition. At the same time, the head solid core filter stick 2 can also block the ash formed by the roasted tobacco well, avoiding ash leakage, i.e. good leak-proof effect.

[0033] Preferably, a plurality of through holes 61 penetrating the inner and outer wall surfaces of the induction ring 6 are uniformly distributed on the side wall of the induction ring 6, so that the roasting efficiency can be improved to a certain extent.

[0034] As Figure 3As shown, preferably, the shortest distance between the outer wall surface of the induction coil 6 and the wrapping paper tube 1 is equal to the distance between the inner wall surface of the induction coil 6 and the central axis of the wrapping paper tube 1. Thus, the above-mentioned arrangement can make the induction coil 6 more centrally located in the tobacco segment 3, so that the induction coil 6 can more evenly roast the tobacco in the tobacco segment 3, so as to further improve the roasting efficiency. In addition, due to the good roasting effect of the tobacco, the tobacco can generate more smoke in a unit of time, so that the user does not need to wait for too long before the next puffing.

[0035] As shown in Figure 3 and Figure 5 , preferably, the hollow filter rod 4 is provided with a first aerosol passage 41 and a second aerosol passage 42 connected in sequence from top to bottom, the upper end of the first aerosol passage 41 is communicated to the tobacco segment 3, and the lower end of the second aerosol passage 42 is communicated to the tail solid core filter rod 5. Thus, due to the first aerosol passage 41 and the second aerosol passage 42 arranged in the hollow filter rod 4, the tobacco smoke will produce a Venturi effect when passing through the two aerosol passages, thereby rapidly reducing the temperature, and then the tobacco smoke enters the tail solid core filter rod 5 for further cooling and filtering before being supplied to the user for smoking, thereby ensuring that the user will not have a burning mouth feeling when smoking.

[0036] As shown in Figure 3 and Figure 5 , in particular, the diameter of the first aerosol passage 41 is smaller than the diameter of the second aerosol passage 42, which can improve the temperature reduction effect of the tobacco smoke to a certain extent.

[0037] As shown in Figure 3 , preferably, the induction coil 6 is arranged in the upper end port of the first aerosol passage 41, so that the tobacco smoke can be more smoothly input into the first aerosol passage 41.

[0038] Preferably, the induction coil 6 is made of a material capable of converting electromagnetic energy into heat. In particular, the induction coil 6 is made of metal or metal alloy, and the thickness is 0.01-0.1mm. More specifically, the material can be preferably selected from iron-nickel alloy, manganese-zinc ferrite material, nickel-zinc ferrite material, cobalt alloy, pure iron or stainless steel. The cobalt alloy is preferably cobalt-based superalloy, rare earth cobalt hard magnetic alloy or tungsten-cobalt alloy; the stainless steel is preferably martensitic steel, ferritic steel, austenitic steel or austenitic-ferritic (dual-phase) stainless steel.

[0039] In combination with Figure 3 , in the embodiment, the length of the head solid core filter rod 2 is 5mm, the lengths of the tobacco segment 3 and the induction coil 6 are both 11mm, the length of the hollow filter rod 4 is 17mm, and the length of the tail solid core filter rod 5 is 11mm. The above-mentioned arrangement can form a cartridge with sufficient length.

[0040] In other embodiments, the materials of the head solid filter rod 2, the hollow filter rod 4 and the tail solid filter rod 5 can also use nicotine molecule branded polymer instead of cellulose acetate. Since the above-mentioned materials are prior art, they will not be described in detail here.

[0041] In combination Figure 6 In use, first, a metal heating element 7 with a plurality of anti-shielding holes 71 is sleeved on the outer side wall of the cartridge, and then the cartridge is inserted into the inner heating type tobacco roaster, and the tobacco roaster is provided with a magnetic induction coil 8 for cooperating with the induction coil 6. Thus, since the metal heating element 7 is provided with the anti-shielding holes 71, the alternating magnetic field generated by the magnetic induction coil 8 after being powered by the power supply can be smoothly induced by the induction coil 6 in the tobacco section 3 and generate heat, thereby achieving the effect of uniformly roasting tobacco in the cigarette section 3. The anti-shielding holes 71 serve to ensure the normal use of the induction coil 6. Of course, the metal heating element 7 can also be heated by connecting a matched heating device, thereby achieving the effect of roasting tobacco outside the cartridge.

[0042] The scope of the present utility model is not defined by the above-described embodiments, but by the appended claims and their equivalents.
