Description

Technical Field

[0001] This utility model relates to the field of vapor-type electronic cigarette technology, and in particular to a cartridge with multiple inhalation ports for vapor-type electronic cigarettes, and also to 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 permeate through the wicking material into the inhalation channel, resulting in persistent leakage, which seriously hinders industry development and affects the quality of the 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 (7). The magnetic heating element (4) is a hollowed-out tubular shape, and the middle part of the magnetic heating element (4) has a smoke flow channel (41) arranged along the length direction. The electronic cigarette atomizer carrier (7) is a column with a hollow flow channel (51) arranged along its length. Its outer diameter is not greater than the inner diameter of the tubular shell (1). The electronic cigarette atomizer carrier (7) is sleeved on the outside of the magnetic heating element (4). The inner surface of the electronic cigarette atomizer carrier (7) is adjacent to the outside of the magnetic heating element (4). Electronic cigarette atomizers are adsorbed inside the electronic cigarette atomizer carrier (7). The lower plug hole (21), the smoke flow channel (41), the upper plug hole (31), and the mouthpiece section (200) are connected.

[0004] However, the capacity of this cartridge is relatively small, and it is usually only suitable for making cartridges with no more than 20 puffs. In order to increase the number of puffs in the cartridge, the inventor proposed this utility model. Utility Model Content

[0005] The purpose of this invention is to overcome the defects of the existing technology and provide a multi-puff cartridge that is simple in structure and easy to manufacture.

[0006] To achieve the above objectives, this utility model provides a multi-puff electronic cigarette cartridge, which includes a matching cartridge shell 9 and a cartridge bottom cover 5. The top of the cartridge shell 9 is a smoke outlet 92. The bottom cover 5 has a vertically penetrating atomizing carrier cavity 51 in the middle. A leak-proof plug 1 is provided at the bottom of the atomizing carrier cavity 51. The leak-proof plug 1 has a leak-proof plug vent 11 in the middle. The oil storage and heating component is placed inside the atomizing carrier cavity 51.

[0007] A middle cover 8 is provided on the top of the bottom cover 5 of the cartridge. The lower end of the middle cover 8 is provided with an end face 82 that matches the atomizing carrier cavity 51. A smoke hole 81 is provided in the middle of the end face. The smoke hole 81 connects the atomizing carrier cavity 51 and the smoke outlet 92.

[0008] The oil storage heating component includes a magnetic heating element 6 and an electronic smoke atomizer carrier 7 that are sleeved together. The magnetic heating element 6 is a tubular shape with at least partial hollowing. At least part of the material of the magnetic heating element 6 is metal, and its middle part has a flue gas channel 61 arranged along the length direction.

[0009] The electronic cigarette atomizer carrier 7 is sleeved on the outside of the magnetic heating element 6, and the inner surface of the electronic cigarette atomizer carrier 7 is adjacent to at least part of the outer side of the magnetic heating element 6; electronic cigarette atomizers are adsorbed inside the electronic cigarette atomizer carrier 7.

[0010] In this invention, for ease of description and not limitation, the direction toward the flue gas outlet 92 is referred to as "up" and the opposite direction as "down". This up-down direction is also called the length direction.

[0011] In a preferred embodiment, the cartridge shell 9 includes a shell body 91 and a smoke pipe 93 connected to a smoke outlet 92. The lower end of the smoke pipe 93 abuts against the upper surface of the cartridge cover 8, and the smoke pipe 93 connects the smoke hole 81 and the smoke outlet 92.

[0012] Preferably, a slot 52 is constructed on the top of the cartridge bottom cover 5, and a protruding edge 83 matching the slot 52 is constructed on the lower part of the cartridge middle cover 8. The cartridge bottom cover 5 and the cartridge middle cover 8 are assembled together by the cooperation of the slot 52 and the protruding edge 83. After assembly, the end face 82 serves as the top surface of the atomized material carrier cavity 51.

[0013] In this invention, the inner cover 8 and the bottom cover 5 of the cartridge are made of heat-resistant silicone, while the outer shell 9 of the cartridge can be made of food-grade PC.

[0014] The atomizing carrier 7 can be made of porous adsorbent material or composed of layered adsorbent materials, such as high-temperature resistant natural fiber cotton, synthetic fiber non-woven fabric or oil-absorbing cotton.

[0015] If necessary, filter rods can be further installed in the flue gas pipe 93. Filter rods are typically used to reduce the temperature of the aerosol, adsorb some substances in the aerosol, or adsorb a small amount of liquid that condenses in the area due to localized temperature reduction. Filter rods can be made of porous materials, foamed materials, or cellulose acetate tows with a certain degree of air resistance.

[0016] 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.

[0017] 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.

[0018] In use, the cartridge of this invention is placed in an electronic cigarette system, and the magnetic heating element 6 should be located within 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 atomized material on the electronic cigarette atomizer carrier 7 to a specific temperature, ensuring that the generated vapor contains the desired aroma and flavor substances.

[0019] The present invention integrates a magnetic heating element and an electronic cigarette atomizer carrier in a bottom cover. At least a portion of the outer wall of the magnetic heating element is in direct contact with the inner wall of the electronic cigarette atomizer carrier. When the magnetic heating element heats up under the action of the magnetic coil, the heat is directly conducted to the electronic cigarette atomizer in contact with it. The electronic cigarette atomizer is heated, atomized, and produces steam. The steam enters the air through the smoke hole 81 and enters the smoke pipe 93, and is eventually inhaled by the consumer.

[0020] The split-type e-cigarette cartridge of this invention has the characteristics of simple structure and large atomization adsorption capacity. Attached Figure Description

[0033] The following embodiments are used to explain the technical solution of this utility model in a non-limiting manner.

[0034] Example 1

[0035] like Figure 1-3 The electronic cigarette cartridge shown includes a cartridge shell 9, a cartridge middle cover 8, and a cartridge bottom cover 5, which are fitted together by conventional limiting mechanisms such as slots and grooves. The cartridge middle cover 8 and the cartridge bottom cover 5 are made of heat-resistant silicone, and the cartridge shell 9 is made of food-grade PC material.

[0036] The cartridge shell 9 is constructed with a smoke outlet 92 at the top and a shell body 91 around the perimeter. A smoke pipe 93 is installed inside the shell body 91 and connected to the smoke outlet 92. The length of the smoke pipe 93 is such that its lower end abuts against the upper surface of the cartridge cover 8.

[0037] The cartridge inner cover 8 and the cartridge bottom cover 5 can be installed together by the engagement of the protruding edge 83 and the slot 52. The cavity in the middle of the cartridge bottom cover 5 is the atomizer carrier cavity 51, which is used to house the magnetic heating element 6 and the electronic cigarette atomizer carrier 7. The lower end of the cartridge inner cover 8 is provided with an end face 82, which matches the atomizer carrier cavity 51, and the end face has a smoke hole 81 in the middle, which is used to connect the atomizer carrier cavity 51 with the smoke outlet 92.

[0038] The magnetic heating element 6 is a hollow tube made of metal, with a flue gas channel 61 arranged along its length in the middle. An electronic cigarette smoke carrier 7 with adsorption properties is sleeved on the outside of the magnetic heating element 6, and electronic cigarette smoke is adsorbed in the electronic cigarette smoke carrier 7.

[0039] Install the smoke cartridge as follows Figure 4-5 The electronic cigarette system shown includes, in addition to the necessary and conventional electronic cigarette casing, bracket, battery, and control board, an air inlet 102 on its casing, which is connected to an air outlet 101 via an air pipe and communicates with the vent hole 11 of the leak-proof plug. When the cartridge is inserted into the electronic cigarette system, the magnetic heating element 6 should be located in the magnetic coil of the electronic cigarette system.

[0040] During use, the magnetic heating element 6 is excited by the coil in the electronic cigarette and heats up. The electronic atomized material on the atomized carrier 7 in contact with it is heated and produces vapor, which enters the smoke channel 61. On the other hand, when the consumer inhales from the smoke outlet, air enters the electronic cigarette from the air inlet, flows into the atomized carrier cavity 51 through the leak-proof vent hole 11, mixes with the atomized vapor to form an aerosol, enters the smoke tube 93 through the smoke hole 81, and is finally inhaled by the consumer from the smoke outlet 92.
