Description

Technical Field

[0001] The present invention relates to the technical field of steam type electronic cigarettes, and in particular to a novel cigarette cartridge for steam type electronic cigarettes, and also to an electronic cigarette system used in conjunction with the cigarette cartridge. Background Art

[0002] Existing steam-type electronic cigarettes (i.e., aerosol atomization systems) are nicotine delivery systems that heat electronic cigarette aerosols to produce a vaporization reaction for consumers to inhale. This type of electronic cigarette system usually adopts the basic structure of a traditional atomizer core with an oil tank, and uses the atomizer core to heat electronic cigarette aerosols to produce aerosols for consumers to inhale. Since the oily electronic cigarette aerosols are directly connected to the suction channel, this type of electronic cigarette system is not a strictly sealed system. The electronic cigarette aerosols will penetrate into the suction channel through the oil-conducting cotton in the system, so there is always a pain point of oil leakage, which seriously troubles the development of the industry and affects the product's inhalation quality.

[0003] In order to solve the problem of liquid electronic cigarette aerosol leakage, the existing technology introduces oil storage cotton, that is, liquid electronic cigarette aerosol is stored in the smoke oil carrier (commonly known as oil storage cotton), and the aerosol in the oil storage cotton is transported to the atomization core through the oil guide cotton on the atomization core, which successfully solves the problem of electronic cigarette oil leakage, and disposable electronic cigarettes are developed based on this technology. However, on the other hand, disposable electronic cigarettes have problems such as environmental protection and waste of resources. At present, many countries have formulated a ban on disposable electronic cigarettes, which has received widespread response from all over the world.

[0004] Therefore, there is an urgent need in the art for an electronic cigarette technology that retains the oil storage cotton structure without wasting resources or causing a large number of battery scraps.

[0005] In addition, all electronic cigarettes may have hygiene problems during consumption, which is caused by the mouthpiece not being kept clean during repeated use and storage. Most of the usage scenarios are to simply wipe the electronic cigarette device or smoke directly without wiping it. There has always been a strong demand for disposable cartridges similar to cigarettes in this field, but due to the complex structure of electronic cigarette cartridges, small-puff disposable cartridges have not been introduced, which is also one of the industry's problems.

[0006] Another major reason why there are no disposable e-cigarette cartridges on the market is that the existing e-cigarette cartridges have a complex structure, so their manufacturing process is complex and costly. The manufacturing cost of a 2 ml standard cartridge is usually more than RMB 5, of which the cost of the atomizer core accounts for a relatively high proportion of the cartridge cost. The market expects that the manufacturing cost of a 2 ml standard cartridge is usually no more than RMB 0.5. Therefore, simplifying the structure of the cartridge and reducing its production difficulty is one of the technical development directions in this field.

[0007] On the other hand, the existing steam-type electronic cigarettes always have the technical pain point of being difficult to truly restore the taste and aroma of tobacco. One of the important reasons is that the amount of high-boiling-point tobacco substances (mainly reducing sugars and various nitrogen-containing compounds, such as various organic acids and amino acids, etc.) added to the electronic cigarette atomizer is strictly limited, and insufficient content of high-boiling-point tobacco substances makes it difficult to restore the tobacco flavor and aroma. Therefore, most of the existing tobacco-flavored electronic cigarettes remain at the level of imitating the taste and aroma of tobacco, and electronic cigarettes that truly present the taste and aroma of tobacco and can restore the taste and aroma of tobacco have always been a technical problem in the industry. As countries around the world begin to implement bans on the production and sale of non-tobacco-flavored electronic cigarettes, the current mainstream flavored (mainly fruit-flavored) electronic cigarettes are about to be banned from sale worldwide, and the research and development of tobacco-flavored steam electronic cigarettes with good restoration is a hot topic in this field. Summary of the invention

[0008] The purpose of the present invention is to overcome the defects of the prior art and provide a new cartridge for use with a steam-type electronic cigarette through structural improvement, so as to reduce the manufacturing cost, simplify the mass production process, and provide a disposable product with a small number of puffs while ensuring good electronic cigarette aerosol storage and atomization functions. In addition, the cartridge is filled with tobacco-flavored electronic cigarette aerosols and equipped with special electronic cigarette equipment, which can also present a better tobacco flavor and aroma.

[0009] In order to achieve the above-mentioned purpose, the present invention provides a new type of cigarette cartridge, which includes a tubular shell 1, a lower plug 2 installed in the lower section of the tubular shell 1, an upper plug 3 installed in the middle section of the tubular shell 1, a metal heating element 4 fixed between the lower plug 2 and the upper plug 3, and an electronic cigarette aerosol carrier 5.

[0010] The tubular housing 1 is made of non-metallic material;

[0011] The lower plug 2 has a lower plug through hole 21 arranged along the length direction, and the upper plug 3 has an upper plug through hole 31 arranged along the length direction. The space surrounded by the tubular shell 1, the lower plug 2 and the upper plug 3 is the electronic cigarette aerosol storage and heating integrated area 100, and the area inside the tubular shell 1 and above the upper plug 3 is the mouthpiece section 200;

[0012] The metal heating element 4 is in a hollow tube shape, and a flue gas flow channel 41 is provided in the middle of the metal heating element 4 along the length direction;

[0013] The electronic cigarette aerosol carrier 5 is a column having a hollow flow channel 51 arranged along the length direction, and its outer diameter is not greater than the inner diameter of the tubular housing 1. The electronic cigarette aerosol carrier 5 is sleeved on the outer side of the metal heating element 4, and the inner surface of the electronic cigarette aerosol carrier 5 is adjacent to the outer side of the metal heating element 4; the electronic cigarette aerosol carrier 5 absorbs the electronic cigarette aerosol;

[0014] The lower plug through hole 21 , the smoke flow channel 41 , the upper plug through hole 31 and the suction nozzle section 200 are connected.

[0015] In the present invention, for the convenience of description but not limitation, the direction toward the bottom cover 8 is referred to as “downward”, and the direction toward the nozzle segment 200 is referred to as “upward”. The up-down direction is also referred to as the length direction.

[0016] In the present invention, the tubular housing 1 has the shape of a hollow tube, and the other elements installed therein therefore have the shape of a hollow column. For ease of manufacture, they can be hollow circular tubes or hollow circular columns, but other polygonal hollow tubes or polygonal hollow columns can also achieve similar functions.

[0017] In the present invention, describing each through hole such as the lower plug through hole 21, the smoke flow channel 41, the upper plug through hole 31 and the mouthpiece section 200 as being arranged along the length direction means that these through holes connect the upper and lower sides of the components to allow aerosol to pass through the components, and does not limit the shape of the through holes. The through hole can be a straight through hole or a curved flow channel.

[0018] In the present invention, a hollow filter rod 6 may be further provided in the mouthpiece section, and a smoke channel 61 is provided in the middle of the hollow filter rod 6 along the length direction. The hollow filter rod 6 is generally used to reduce the temperature of the aerosol, adsorb part of the substances in the aerosol, or adsorb the liquid condensed in the area due to the local temperature reduction. Porous materials, foaming materials or acetate fiber bundles are all common materials for preparing the hollow filter rod 6.

[0019] Furthermore, in order to facilitate assembly or positioning, a filter rod holder 7 may be provided in the nozzle section 200 . The filter rod holder 7 is tubular and has a hollow filter rod accommodating cavity 71 provided in the middle along the length direction. The accommodating cavity is used to accommodate the hollow filter rod 6 .

[0020] As another preferred embodiment, a bottom cover 8 matching the tubular housing 1 is installed below the lower plug 2 , and a bottom cover through hole 81 is defined in the bottom cover 8 , and the bottom cover through hole 81 is communicated with the lower plug through hole 21 .

[0021] Optionally, there is a bottom cover cavity 82 between the lower surface of the lower plug 2 and the upper surface of the bottom cover 8, and a loose adsorption material is arranged in the bottom cover cavity 82. The loose adsorption material, such as a small amount of non-woven fabric, is used to absorb a small amount of liquid that may drip or leak from the electronic cigarette aerosol storage and heating integrated area 100, but should avoid blocking the gas flow channel between the lower plug 2 and the bottom cover 8.

[0022] In the present invention, the integrated storage and heating area for electronic cigarette aerosols is used to store electronic cigarette aerosols and provide a space for the electronic cigarette aerosols to be heated to generate aerosols. Therefore, the integrated storage and heating area for electronic cigarette aerosols surrounded by the lower surface of the upper plug 3, the upper surface of the lower plug 2 and the inner wall of the tubular shell 1 is a columnar space as a whole, and the metal heating element 4 and the electronic cigarette aerosol carrier 5 are fixed therein.

[0023] For the electronic cigarette aerosol storage and heating integrated area 100, since the metal heating element 4 and the electronic cigarette aerosol carrier 5 are integrally coaxially installed together as a hollow column and are fixed here together, one way to fix the metal heating element 4 and the electronic cigarette aerosol carrier 5 is to abut them through the upper plug 3 and the lower plug 2 to prevent them from moving.

[0024] Another fixing method is to set a limiting mechanism on the upper surface of the lower plug 2 that matches the bottom of the metal heating element 4. Preferably, the limiting mechanism is a boss 22 set in the middle of the upper surface of the lower plug 2, and the outer diameter of the boss 22 matches the inner diameter of the metal heating element 4, so as to facilitate fixing them together. At this time, the length of the metal heating element 4 can be less than the length of the electronic cigarette aerosol carrier 5 to avoid the top of the metal heating element 4 directly contacting the lower surface of the upper plug 3, and to avoid the lower surface of the upper plug 3 from being deformed due to possible excessive heating.

[0025] In a preferred embodiment, the outer surface of the electronic cigarette aerosol carrier 5 is adjacent to the inner wall of the tubular housing 1 .

[0026] The electronic cigarette aerosol carrier 5 is used to absorb and load the electronic cigarette aerosol (commonly known as electronic cigarette oil). When the metal heating element 4 is heated by electromagnetic induction, the electronic cigarette aerosol in direct contact with the heating element is heated to generate aerosol, which fills the smoke flow channel 41. Therefore, in order to achieve this function, the electronic cigarette aerosol carrier 5 can be a hollow column made of porous adsorption material, or a hollow column composed of rolled and stacked layered adsorption materials, or they can be wrapped on the outside of the metal heating element 4. As long as the adsorption of liquid substances can be achieved, the technical solution of the present invention can be achieved.

[0027] In the present invention, the layered adsorbent material includes one or more layered materials selected from the group consisting of high temperature resistant natural fiber cotton and / or non-woven fabric and / or oil absorbent cotton, and each material can be single-layered or multi-layered. Among them, the high temperature resistant natural fiber cotton is, for example, high temperature resistant linen cotton, and these layered adsorbent materials are all materials that can be purchased on the market. These layered adsorbent materials can be used alone or in combination, and they all have certain adsorption properties.

[0028] When multiple layered adsorption materials are used, if the material includes high temperature resistant natural fiber cotton, the high temperature resistant natural fiber cotton is preferably adjacent to the metal heating element 4 to exert its high temperature resistance and better avoid local carbonization that may occur when the metal heating element 4 is heated. If the material includes oil-absorbing cotton, the oil-absorbing cotton is preferably arranged in the outermost layer to exert its excellent adsorption properties.

[0029] In another optional embodiment, the outer surface of the electronic cigarette aerosol carrier 5 is not adjacent to the inner wall of the tubular housing 1. In this case, the space enclosed by the outer surface of the electronic cigarette aerosol carrier 5 and the inner wall of the tubular housing 1 can be filled with electronic cigarette aerosol. Since the stock liquid usually has a certain viscosity and a large tension, and the electronic cigarette aerosol carrier 5 also has a certain density, the smoke flow channel 41 in the middle of the metal heating element 4 can still be unobstructed.

[0030] In the present invention, the metal heating element 4 has at least a partial hollow area to ensure that when the electronic cigarette aerosols on the electronic cigarette aerosol carrier 5 are heated to generate aerosols, these aerosols can enter the smoke flow channel 41 in the middle of the metal element. As a preferred embodiment of the present invention, the metal heating element 4 includes a lower end support 42, an upper end support 43 and ribs 44 connecting the upper and lower end supports, and the number of ribs 44 is 3 to 12.

[0031] In the present invention, the function of the "rib" is to connect the ribs 44 of the upper and lower end supports, so it can be a straight rib, or have a curved shape or other shapes that are convenient for manufacturing.

[0032] As an optional embodiment, the metal heating element 4 is in a hollow circular tube shape, and the lower end support 42 and the upper end support 43 are circular rings. Alternatively, the metal heating element 4 is in a hollow polygonal column shape, and the lower end support 42 and the upper end support 43 are corresponding polygonal rings.

[0033] The metal heating element 4 can be formed by weaving metal wires, or by stamping, casting or corrosion forming of metal materials. The production process of the metal heating element 4 should not be limited, as long as the bracket has the necessary hardness and can be set in the electronic cigarette aerosol storage and heating integrated area 100.

[0034] In the present invention, the upper plug 3 and the lower plug 2 are made of silicone, preferably food grade silicone.

[0035] The tubular housing 1 is made of non-metallic materials. In the present invention, non-metallic materials are a general term for all materials other than metal materials. They do not have the characteristics of metal materials, do not generate induced electromotive force, do not generate eddy current, do not generate heat, and do not shield the magnetic field in an alternating magnetic field. Non-metallic materials can be organic, inorganic, or various materials obtained by physical or chemical treatment of organic and inorganic materials. Rubber, ceramics, wood, paper, and various plastics can all implement the technical solution of the present invention.

[0036] Considering that the electronic cigarette system is usually handheld in size, as part of a portable handheld device, the outer diameter of the metal heating element 4 is 2-20 mm and the length is 2-100 mm, which is reasonable and convenient for industrial production. The outer diameter of the tubular housing 1 is 4-30 mm and should be larger than the outer diameter of the metal heating element 4.

[0037] In the present invention, the metal heating element 4 is made of electromagnetic induction material, usually metal material such as stainless steel. Those skilled in the art can also select other easily available electromagnetic induction materials according to the prior art.

[0038] The present invention also provides an electronic cigarette system used in conjunction with the above-mentioned novel cigarette cartridge, in particular, a steam-type electronic cigarette system that realizes heating through electromagnetic induction.

[0039] The steam type electronic cigarette system that realizes heating by electromagnetic induction belongs to the prior art in this field. The system generally includes an electronic cigarette housing, a battery arranged in the electronic cigarette housing, an electromagnetic induction coil connected to the battery, and necessary electric control components. When the electric control component outputs an electric control signal, the battery outputs a high-frequency alternating current to the coil, and the coil generates a high-frequency alternating magnetic field.

[0040] When in use, the new cigarette cartridge of the present invention is set in the electronic cigarette system, and the metal heating element 4 should be located in the magnetic induction coil of the electronic cigarette system. Based on the principle of electromagnetic induction heating, when the electronic control system of the electronic cigarette system provides a high-frequency current with a certain voltage and frequency to the magnetic induction coil, a high-frequency alternating magnetic field is generated inside the coil. In this way, an alternating eddy current with the same frequency as the coil is generated inside the metal heating element arranged in the high-frequency alternating magnetic field to achieve heating. Those skilled in the art can implement frequency conversion management of the coil through program control of the IC, so that the metal heating element has heating curve management, which is convenient for the electronic cigarette aerosol on the electronic cigarette aerosol carrier 5 to be heated to a specific temperature, ensuring that the generated vapor contains the desired flavor and aroma substances.

[0041] The novel cigarette cartridge of the present invention arranges a metal heating element and an electronic cigarette aerosol carrier together, wherein the outer wall surface of the metal heating element is in direct contact with the inner wall surface of the electronic cigarette aerosol carrier. When the bracket heats up under the action of the magnetic induction coil, the heat is directly transferred to the electronic cigarette aerosol in contact with it, and the electronic cigarette aerosol is heated, atomized and generates steam. The steam enters the hollow smoke flow channel and flows to the mouthpiece section under the negative pressure provided by the user's inhalation action.

[0042] In addition, when the new type of cigarette cartridge of the present invention is used as a MINI type small-puff cigarette cartridge, due to the small number of puffs (usually less than 30 puffs), the problem of carbon deposition in the core has not yet occurred when the electronic cigarette aerosol is consumed, thereby effectively avoiding the problem of taste deviation caused by carbon deposition on the metal heating element when using electronic cigarette aerosol with original tobacco flavor.

[0043] The novel cigarette cartridge of the present invention has the characteristics of small volume, simple structure and easy production. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The following examples are used to explain the technical solutions of the present invention in a non-limiting manner.

[0065] Example 1

[0066] like Figure 1-3 The new cigarette cartridge shown comprises a tubular shell 1, a lower plug 2, an upper plug 3, a metal heating element 4, an electronic cigarette aerosol carrier 5, a hollow filter rod 6 and a bottom cover 8.

[0067] The tubular housing 1 is a plastic tube with an inner diameter of about 8 mm. The lower plug 2 is installed at the lower part thereof, and the upper plug is installed at the middle part thereof. Through holes are provided in the middle parts of the lower plug and the upper plug along the length direction as gas flow channels.

[0068] Lower plug 2 Figure 4C As shown, its upper surface is configured as a boss 22 so that the metal heating element is fixed together with the boss 22. The side of the lower plug is fixed to the tubular housing 1 through an external thread or a sealing ring.

[0069] Metal heating element 4 Figure 4B As shown, it includes a circular lower end support 42 and an upper end support 43, which are fixedly connected by four ribs 44. Therefore, the area between adjacent ribs 44 and the support is hollow, which is convenient for aerosol to pass through.

[0070] The inner diameter of the lower end support 42 matches the outer diameter of the boss 22 , so that the metal heating element is mounted on the boss 22 .

[0071] Electronic cigarette aerosol carrier 5 Figure 4DAs shown, there is a hollow flow channel 51 arranged along the length direction, which is sleeved on the outside of the metal heating element 4, and its inner surface is adjacent to the outside of the metal heating element 4, and its outer surface is adjacent to the inner wall of the tubular shell 1. The electronic cigarette aerosol carrier 5 absorbs liquid electronic cigarette aerosol, so part of the electronic cigarette aerosol directly contacts the surface of the metal heating element.

[0072] The bottom surface of the electronic cigarette aerosol carrier 5 abuts against the upper surface of the lower plug 2, and the top surface abuts against the lower surface of the upper plug 3, so that it is confined in the electronic cigarette aerosol storage and heating integrated area without displacement.

[0073] In this embodiment, the electronic cigarette aerosol carrier 5 is composed of a layer of high temperature resistant natural fiber cotton, a layer of non-woven fabric and multiple layers of oil-absorbing cotton rolled and stacked in sequence.

[0074] A hollow filter rod 6 made of acetate fiber tow is arranged above the upper plug 3, such as Figure 4D shown.

[0075] When in use, the novel cigarette cartridge of the present invention is configured in an electromagnetic induction heating electronic cigarette system, and the metal heating element 4 should be located in the magnetic induction coil of the electronic cigarette system. When the heavy magnetic induction coil of the electronic cigarette system is controlled to generate a high-frequency alternating magnetic field, an alternating eddy current with the same frequency as the coil is generated inside the metal heating element arranged in the high-frequency alternating magnetic field to achieve heating. The electronic cigarette aerosol on the electronic cigarette aerosol carrier 5 is heated to a specific temperature, and the generated steam enters the smoke flow channel and then flows to the mouthpiece section.

[0076] Example 2

[0077] The same structure as embodiment 1, the difference is that the structure of the bottom cover 8 and the lower plug 2 is as follows Figure 5C-5D There is a bottom cover cavity 82 between the upper surface of the bottom cover 8 and the lower surface of the lower plug 2, and a small amount of non-woven fabric can be filled in the bottom cover cavity 82 to absorb a very small amount of leaked electronic cigarette aerosols, but it does not affect the airflow from the bottom cover through hole 81 to the lower plug through hole 21.

[0078] In addition, in order to prevent the hollow filter rod 6 from being displaced in the tubular housing 1 , a filter rod holder 7 is provided in the tubular housing 1 to fix the hollow filter rod 6 in the hollow filter rod accommodating cavity 71 .
