Description

Technical Field

[0001] This invention relates to the field of vapor-type electronic cigarette technology, and particularly to a leak-proof 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 in practical applications that the structure of the novel e-cigarette cartridge could be further optimized to further improve its anti-leakage performance and completely prevent oily e-cigarette vapors from seeping out from product interfaces or gaps. 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 leak-proof cartridge for use with vapor-type electronic cigarettes through structural improvements. While ensuring good storage and atomization functions of electronic cigarette atomizers, it improves the leak-proof performance. On the other hand, it is expected to simplify the product structure and reduce manufacturing costs.

[0006] To achieve the above objectives, this utility model provides a leak-proof e-cigarette cartridge, which includes a tubular outer shell 1, a central plug 3 installed in the middle section inside the tubular outer shell 1, a magnetic heating element 4 disposed below the central plug 3, and an electronic atomizing agent carrier 5. The tubular outer shell 1 is made of non-metallic material. The bottom of the tubular outer shell 1 is closed to form an outer shell bottom 11. The central plug 3 has a central through hole 31 arranged along the length direction and a surrounding through hole 32 communicating with the central through hole 31. The space enclosed by the tubular outer shell 1 and the central plug 3 is an integrated electronic atomizing agent storage and heating area 100. The area inside the tubular outer shell 1 and above the central plug 3 is the mouthpiece section 200.

[0007] 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.

[0008] 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.

[0009] The tubular outer shell 1 is provided with side vents 12, and at least a portion of the side vents 12 are in communication with at least a portion of the surrounding through holes 32;

[0010] The flue gas flow channel 41, the central through hole 31, and the suction nozzle section 200 are connected.

[0011] In this invention, for ease of description and not limitation, the direction toward the bottom 11 of the outer shell is referred to as "down," and the direction toward the nozzle section 200 is referred to as "up." This up-down direction is also called the length direction.

[0012] 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.

[0013] In this invention, describing the through holes (such as the flue gas flow channel 41, the central through hole 31, and the nozzle 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.

[0014] As an optional implementation, a heat insulation pad 7 is provided at the bottom of the integrated heating and storage area 100 for electronic cigarette smoke, with at least a portion of the surface of the heat insulation pad 7 abutting against the magnetic heating element 4. The heat insulation pad 7 can be used to separate the magnetic heating element 4 from the bottom 11 of the tubular housing 1, preventing the bottom of the tubular housing 1 from excessively aging when the magnetic heating element 4 is heated.

[0015] As another optional implementation, when the material of the tubular outer shell 1 is heat-resistant and there is no need to install the heat insulation pad 7, a limiting mechanism matching the bottom of the magnetic heating element 4 can be provided on the upper surface of the bottom 11 of the outer shell to reduce the relative displacement between the magnetic heating element 4 and the tubular outer shell 1.

[0016] To prevent the outer shell material from aging excessively, the middle plug 3 and the heat insulation pad 7 are preferably made of food-grade silicone, which has certain heat resistance properties.

[0017] Optionally, a filter rod 6 may be provided in the suction nozzle 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 may have a flue gas channel 61 arranged along its length in the middle of the filter rod.

[0018] 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.

[0019] In this invention, when the various components of the e-cigarette cartridge are assembled together, the bottom surface of the electronic atomizing carrier 5 abuts against the upper surface of the bottom 11 of the tubular outer shell 1, and the top surface abuts against the lower surface of the middle plug 3.

[0020] When a consumer inhales, air enters through the side vent 12, creating negative pressure in the surrounding through-holes 32 and the central through-hole 31. The electronic atomized substance in the electronic atomized substance carrier 5 is heated to generate an aerosol, which then enters the smoke flow channel 41 and, under the action of negative pressure, enters the central through-hole 31 and is eventually inhaled by the consumer.

[0021] In this invention, the integrated storage and heating area 100 for electronic cigarette atomizers is used to store electronic cigarette atomizers and provides a space for the electronic cigarette atomizers to generate aerosols when heated. Therefore, the integrated storage and heating area 100 for electronic cigarette atomizers, which is surrounded 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 and the electronic cigarette atomizer carrier 5 are fixed.

[0022] 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 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] As a feasible embodiment of this utility model, the magnetic heating element 4 includes a lower end support 42, an upper end support 43, and a rib 44 connecting the upper and lower end supports located at the upper and lower ends. The function of the "rib" is to connect the upper and lower end supports. Therefore, the rib 44 can be a straight rib, or it can be curved or have other shapes that are easy to manufacture.

[0027] The magnetic heating element 4 can be made by weaving metal wires or by stamping, casting, or etching metal materials. Alternatively, metal and non-metal materials can be spliced ​​together to form a heating element with partially hollowed-out areas. The manufacturing process of the magnetic heating element 4 should not be limited, as long as the bracket has the necessary rigidity to ensure that it can be placed within the integrated heating and storage area 100 of the electronic cigarette atomizer.

[0028] In this invention, the tubular outer shell 1 is made of non-metallic material. In this invention, non-metallic material refers to all materials other than metallic materials. These materials do not possess the properties of metallic materials; they do not generate induced electromotive force, eddy currents, or heat in an alternating magnetic field, nor do they 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.

[0029] Considering that electronic cigarette systems are typically handheld in size, it is reasonable and convenient for industrial production for the magnetic heating element 4 to have an outer diameter of 2-20mm and a length of 2-100mm as part of a portable handheld device. The tubular outer shell 1 has an outer diameter of 4-30mm and should be larger than the outer diameter of the magnetic heating element 4.

[0030] 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.

[0031] This invention also provides an electronic cigarette system for use with the aforementioned cartridges, particularly a vapor-type electronic cigarette system that achieves heating through electromagnetic induction.

[0032] 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.

[0033] In use, the leak-proof cartridge of this invention is placed in the electronic cigarette system, 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. Thus, the magnetic heating element, placed within this high-frequency alternating magnetic field, generates an alternating eddy current with the same frequency as the coil, thus generating heat. Those skilled in the art can use an IC to program and control the frequency conversion management of the coil, enabling the magnetic heating element to have a heating curve management function. This facilitates the heating of the electronic cigarette atomizer on the electronic cigarette atomizer carrier 5 to a specific temperature, ensuring that the generated vapor contains the desired aroma and flavor substances.

[0034] The leak-proof e-cigarette cartridge of this utility model combines a magnetic heating element with an e-cigarette atomizing carrier. The outer wall of the magnetic heating element is in direct contact with the inner wall of the e-cigarette atomizing carrier. When the support is heated by the magnetic coil, the heat is directly conducted to the e-cigarette atomizing carrier in contact with it. The e-cigarette atomizing carrier is heated, atomized and generates steam. The steam enters the smoke flow channel with the air entering through the side air hole 12 and flows to the mouthpiece section under the negative pressure provided by the user's inhalation action.

[0035] The e-cigarette cartridge of this invention is characterized by its small size, simple structure, non-leakage, 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 1-2 The novel e-cigarette cartridge shown includes a tubular outer shell 1, a central plug 3, a magnetic heating element 4, an e-cigarette atomizer 5, a filter rod 6, and a heat insulation pad 7. The central plug 3 and the heat insulation pad 7 are made of food-grade silicone.

[0054] The tubular outer shell 1 is a plastic tube with an inner diameter of approximately 8 mm, made of food-grade PC, and has a closed bottom structure forming the shell bottom 11. The middle plug 3 is installed in the middle, and the middle plug divides the space inside the shell into an integrated area 100 for storing and heating electronic atomized substances and a mouthpiece section 200.

[0055] Central Severance Figure 7 As shown, the tubular outer shell 1 has a central through-hole 31 that extends through both the top and bottom ends, and a concave structure is constructed in the middle waist section as a surrounding through-hole 32, so that the surrounding through-hole 32 communicates with the central through-hole 31. Side vents 12 are provided on the tubular outer shell 1, and the positions of the side vents 12 match the surrounding through-holes 32 to ensure that the side vents 12 communicate with the surrounding through-holes 32 in the assembled state.

[0056] Magnetic heating element 4 Figure 5 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.

[0057] Electronic vapor carrier 5 such as Figure 6 As shown, non-woven fabric is wrapped around the outside of the magnetic heating element 4 to form an electronic cigarette atomizer carrier 5 that is basically hollow cylindrical, with its inner surface adjacent to the outer surface of the magnetic heating element 4. Liquid electronic cigarette atomizer is adsorbed inside the electronic cigarette atomizer carrier 5, so some of the electronic cigarette atomizer directly contacts the metal material surface of the magnetic heating element.

[0058] A filter rod 6 made of cellulose acetate bundles is installed above the middle stopper 3, such as... Figure 4 As shown.

[0059] In use, the novel tobacco cartridge of this invention is configured in an electromagnetic induction heating electronic cigarette system, with the magnetic heating element 4 located within 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 this high-frequency alternating magnetic field, thus achieving heating. The aerosol on the electronic cigarette aerosol carrier 5 is heated to a specific temperature, and the generated vapor enters the smoke flow channel 41. Under the consumer's inhalation action, air enters from the side air hole 12, passes through the surrounding through holes 32, and enters the central through hole 31, carrying out the aerosol in the smoke flow channel 41, which is ultimately inhaled by the consumer.
