Description

Technical Field

[0001] This utility model relates to the field of vapor-type electronic cigarette technology, and in particular to a split-type cartridge for vapor-type electronic cigarettes, as well as an electronic cigarette system used in conjunction with the cartridge. Background Technology

[0002] Existing vapor-type electronic cigarettes (i.e., aerosol atomization systems) are nicotine delivery systems that deliver nicotine by heating the atomized e-cigarette to induce a vaporization reaction and produce an aerosol for the consumer to inhale. These systems typically employ a traditional atomizer coil and e-liquid tank structure, using the coil to heat the e-cigarette to generate an aerosol for the consumer to inhale. Because the e-cigarette's oily atomized substance is directly connected to the inhalation channel, these systems are not strictly sealed. The atomized substance can seep into the inhalation channel through the wicking material within the system, resulting in persistent leakage, a significant problem that severely hinders industry development and affects the quality of the inhaled product.

[0003] To address the leakage problem of liquid e-cigarette vaporizers, Chinese utility model patent application CN2024112435296 discloses a novel e-cigarette cartridge, the structure of which includes a tubular outer shell (1), a lower plug and an upper plug installed inside the tubular outer shell, a magnetic heating element (4) fixed between the lower plug and the upper plug (3), and an e-cigarette vaporizer carrier (5). The magnetic heating element (4) is a hollowed-out tubular shape, and the middle of the magnetic heating element (4) has a vapor flow channel (41) arranged along the length direction. The electronic cigarette atomizer carrier (5) is a column with a hollow flow channel (51) arranged along the length direction. Its outer diameter is not greater than the inner diameter of the tubular shell (1). The electronic cigarette atomizer carrier (5) is sleeved on the outside of the magnetic heating element (4). The inner surface of the electronic cigarette atomizer carrier (5) is adjacent to the outside of the magnetic heating element (4). Electronic cigarette atomizers are adsorbed inside the electronic cigarette atomizer carrier (5). The lower plug hole (21), the smoke flow channel (41), the upper plug hole (31), and the mouthpiece section (200) are connected.

[0004] The inventors discovered during actual research and development that separating the filter rod and heating element of the e-cigarette cartridge, allowing the two parts to be disassembled, would facilitate product testing during the product development and testing phases. Therefore, this utility model was proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the defects of the existing technology and provide a new split cartridge for use with vapor-type electronic cigarettes through structural improvements. The filter rod part and the heating part of the cartridge are set separately, so that the filter rod part can be replaced separately after the cartridge is inserted into the electronic cigarette device during the research and development and testing stages.

[0006] To achieve the above objectives, this utility model provides a split-type e-cigarette cartridge, which includes an independent mouthpiece assembly and a heating assembly. The mouthpiece assembly includes a tubular outer shell 1 and a central plug 3 installed in the middle section inside the tubular outer shell 1. The tubular outer shell 1 is made of non-metallic material. The central plug 3 has a central plug through hole 31 arranged along the length direction. The central plug 3 divides the space inside the tubular outer shell 1 into upper and lower parts, wherein the lower part is an integrated area 100 for storing and heating electronic atomized substances, and the upper part is a mouthpiece section 200.

[0007] The heating assembly includes a magnetic heating element 4, an electronic smoke atomizer carrier 5, and a heating element shell 2, which are connected together from the inside to the outside.

[0008] The magnetic heating element 4 is at least partially hollowed out in the shape of a tube. At least part of the material of the magnetic heating element 4 is metal, and the middle part has a flue gas passage 41 arranged along the length direction.

[0009] The electronic cigarette atomizer carrier 5 is sleeved on the outside of the magnetic heating element 4, and the inner surface of the electronic cigarette atomizer carrier 5 is adjacent to at least part of the outer side of the magnetic heating element 4; electronic cigarette atomizers are adsorbed inside the electronic cigarette atomizer carrier 5.

[0010] The heating element shell 2 is sleeved on the outside of the electronic cigarette atomizing carrier 5, and a limiting mechanism 21 matching the lower edge of the tubular shell 1 is provided in the middle of the outer wall of the heating element shell 2.

[0011] The upper part of the heating assembly is assembled in the electronic cigarette atomizer storage and heating integrated area 100, so that the smoke flow channel 41, the middle plug hole 31 and the mouthpiece section 200 are connected.

[0012] In this invention, for ease of description and not limitation, the direction toward the electronic cigarette device 300 is referred to as "down," and the direction toward the mouthpiece section 200 is referred to as "up." This up-down direction is also called the length direction.

[0013] In this invention, the tubular outer shell 1 has the shape of a hollow tube, and the other components installed therein therefore have the shape of a column or hollow column to facilitate their assembly. For ease of manufacture, their cross-sections can be circular, but other cross-sections of polygonal hollow tubes or polygonal hollow columns can also achieve similar functionality.

[0014] In this invention, describing the through holes (such as the flue gas flow channel 41, the central 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 ends of the component to allow aerosol to pass through each component, and does not limit the shape of the through holes. The through holes can be straight or curved flow channels. When certain components are made of breathable materials, such as filter rods made of conventional filter rod materials like foamed silicone or cellulose acetate, through holes are unnecessary because the flue gas can pass through these materials.

[0015] In this invention, the tubular outer shell 1 and the heating element outer shell 2 are preferably made of food-grade PC material. To prevent excessive aging of the outer shell material, the middle plug 3 is preferably made of silicone, which has certain heat resistance.

[0016] Optionally, a filter rod 6 may be provided in the suction section 200. The filter rod 6 is typically used to reduce the aerosol temperature, adsorb some substances in the aerosol, or adsorb a small amount of liquid that condenses in the area due to local temperature reduction. The filter rod 6 may be made of porous material, foam material, or cellulose acetate tow with a certain air resistance, or it may have a flue gas channel arranged along its length in the middle of the filter rod.

[0017] Furthermore, to facilitate assembly or positioning, conventional mechanisms such as limiting protrusions for restricting filter rod displacement can be provided on the inner wall of the nozzle section 200.

[0018] In this invention, when the upper part of the heating assembly is assembled in the integrated heating and storage area 100 of the electronic cigarette atomizer, the upper end of the heating element shell 2 abuts against the lower surface of the middle plug 3.

[0019] In this invention, the integrated storage and heating area 100 for electronic cigarette atomizers is used to accommodate the heating assembly. Therefore, the integrated storage and heating area 100 for electronic cigarette atomizers, which is formed by the lower surface of the central plug 3 and the inner wall of the tubular outer shell 1, is a columnar space in which the magnetic heating element 4, the electronic cigarette atomizer carrier 5, and the heating element shell 2 are fixed.

[0020] The e-cigarette atomizer carrier 5 is used to adsorb and load e-cigarette atomizers (commonly known as e-cigarette liquids). When the metal part of the magnetic heating element 4 is heated by electromagnetic induction, the e-cigarette atomizers in direct contact with the magnetic heating element generate aerosols, which fill the smoke flow channel 41. Therefore, to achieve this function, the e-cigarette atomizer carrier 5 can be a hollow column made of porous adsorbent material, or a hollow column composed of rolled and stacked layered adsorbent material, or they can be wrapped around the outside of the magnetic heating element 4. As long as the adsorption of liquid substances can be achieved, the technical solution of this utility model can be realized.

[0021] In this invention, the layered adsorbent material comprises one or more of the following materials: high-temperature resistant natural fiber cotton and / or non-woven fabric and / or one or more layers of man-made fiber non-woven fabric and / or oil-absorbing cotton. Each material can be a single layer or multiple layers. High-temperature resistant natural fiber cotton, such as high-temperature resistant flax cotton, is a commercially available material. These layered adsorbent materials can be used individually or in combination, and all possess certain adsorption properties.

[0022] When using multiple layered adsorption materials, if the material includes high-temperature resistant natural fiber cotton, the high-temperature resistant natural fiber cotton is preferably adjacent to the magnetic heating element 4 to leverage its high-temperature resistance and better prevent localized carbonization that may occur when the magnetic heating element 4 heats up. If the material includes oil-absorbing cotton, the oil-absorbing cotton is preferably placed on the outermost layer to leverage its excellent adsorption properties.

[0023] In this invention, the magnetic heating element 4 has at least a partially hollowed-out area and at least a portion of the material is metal, ensuring that when the electronic atomized atomized material on the electronic atomized atomized material carrier 5 is heated to generate aerosols, these aerosols can enter the flue gas channel 41 in the middle of the metal part.

[0024] As a feasible implementation of this utility model, the magnetic heating element 4 can be made by weaving metal wires or by stamping, casting or etching metal materials. Alternatively, metal materials and non-metal materials can be spliced ​​together to form a heating element with a partially hollowed-out area. The production process of the magnetic heating element 4 should not be limited.

[0025] In this invention, both the tubular outer shell 1 and the heating element shell are made of non-metallic materials. In this invention, non-metallic materials refer to all materials other than metallic materials. They do not possess the properties of metallic materials, do not generate induced electromotive force, eddy currents, or heat in an alternating magnetic field, and do not shield the 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 be used to implement the technical solution of this invention.

[0026] Considering that electronic cigarette systems are typically handheld in size, the outer diameter of the tubular housing 1, as part of a portable handheld device, is typically 4-30 mm and the length is 2-8 cm.

[0027] In this invention, at least a portion of the material of the magnetic heating element 4 is an electromagnetic induction material, typically a metal such as stainless steel. Those skilled in the art can also select other readily available electromagnetic induction materials to manufacture it based on existing technology.

[0028] This utility model also provides an electronic cigarette system for use with the above-mentioned cartridge. The electronic cigarette system has a heating chamber 303 for inserting the cartridge. An air outlet 302 is provided at the bottom of the heating chamber 303, and an air inlet 301 is provided in the outer shell of the electronic cigarette system. The air outlet 302 and the air inlet 301 are connected through an air flow channel. When the split cartridge is inserted into the heating chamber 303, the position of the air outlet 302 matches the bottom of the electronic cigarette atomizer carrier 5.

[0029] Vapor-type electronic cigarette systems that achieve heating through electromagnetic induction are existing technologies in this field. Such systems typically include an electronic cigarette casing, a battery housed within the casing, an electromagnetic induction coil connected to the battery, and necessary electronic control components. When the electronic control components output an electronic control signal, the battery outputs a high-frequency alternating current to the coil, which in turn generates a high-frequency alternating magnetic field.

[0030] In use, the split-type cartridge of this invention is placed in the heating chamber 303 of the electronic cigarette, and the magnetic heating element 4 should be located in the magnetic 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 coil, a high-frequency alternating magnetic field is generated inside the coil. In this way, the magnetic heating element placed in this high-frequency alternating magnetic field generates an alternating eddy current with the same frequency as the coil, thereby achieving heating. Those skilled in the art can use IC to program control to realize the frequency conversion management of the coil, so that the magnetic heating element has heating curve management, which makes it easy for the electronic atomized material on the electronic atomized material carrier 5 to be heated to a specific temperature, ensuring that the generated vapor contains the desired aroma and fragrance substances. When the magnetic heating element 4 heats up under the action of the magnetic coil, the heat is directly conducted to the electronic atomized material in contact with it, and the electronic atomized material is heated, atomized and generates vapor. The vapor enters the hollow smoke flow channel, and under the negative pressure provided by the user's inhalation action, it flows to the mouthpiece section along with the air from the air outlet 302.

[0031] The modular e-cigarette cartridge of this invention is characterized by its small size, simple structure, and ease of manufacturing. Attached Figure Description

[0051] The following embodiments are used to explain the technical solution of this utility model in a non-limiting manner.

[0052] Example 1

[0053] like Figure 1-3 The shown is a split-type e-cigarette cartridge, which includes a separate mouthpiece assembly and a heating assembly.

[0054] The mouthpiece assembly includes a tubular outer shell 1, a silicone central plug 3, and a cellulose acetate filter rod 6.

[0055] The tubular outer shell 1 is a plastic tube with an inner diameter of approximately 8 mm, made of food-grade PC. A central plug 3 is installed in the middle of the tube, which divides the internal space of the outer shell into an integrated area 100 for storing and heating electronic atomized substances and a mouthpiece section 200. The central plug has a central plug through hole 31.

[0056] The heating assembly consists of a magnetic heating element 4, an electronic smoke atomizing carrier 5, and a heating element shell 2 that are connected together. The outer wall of the heating element shell 2 is constructed with a convex edge in the middle as a limiting mechanism 21, so that when the heating element shell 2 is installed in the tubular shell 1, its upper end abuts against the lower surface of the middle plug 3.

[0057] Magnetic heating element 4 Figure 9 As shown, it includes a lower end support 42 and an upper end support 43 made of metal in a basically circular shape, which are fixedly connected by four ribs 44. Therefore, the area between adjacent ribs 44 and the support is hollowed out to facilitate the passage of aerosols.

[0058] Electronic vapor carrier 5 such as Figure 7 As shown, non-woven fabric is wrapped around the outside of the magnetic heating element 4 to form an electronic smoke atomizer carrier 5 that is basically hollow and cylindrical, and then installed inside the heating element shell 2 made of food-grade PC. Liquid electronic smoke atomizer is adsorbed inside the electronic smoke atomizer carrier 5, so some of the electronic smoke atomizer directly contacts the metal surface of the magnetic heating element.

[0059] To ensure that the smoke can be inhaled, the electronic cigarette system used with the cartridge has a heating chamber 303 for inserting the cartridge. In addition, the electronic cigarette casing is provided with an air inlet 301, which is connected to an air outlet 302 through an air flow channel. When the cartridge in this embodiment is inserted into the heating chamber 303, the position of the air outlet 302 matches the bottom of the electronic cigarette atomizer carrier 5.

[0060] In use, the novel tobacco cartridge of this invention is configured in an electronic cigarette system with electromagnetic induction heating. The magnetic heating element 4 should be located in the magnetic coil of the electronic cigarette system. When the magnetic 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 magnetic heating element placed within the high-frequency alternating magnetic field, thereby achieving heating. The electronic atomized material on the electronic cigarette atomizer carrier 5 is heated to a specific temperature, and the generated vapor enters the smoke flow channel. As the consumer inhales, air enters from the air inlet 301, flows from the air outlet 302 to the electronic atomized material carrier 5, then enters the smoke flow channel, and then flows with the smoke to the mouthpiece section.
