[0028] The description of the embodiments of this specification should be combined with the corresponding drawings, which should be considered as part of the complete specification. In the drawings, the shape or thickness of the embodiments may be enlarged and indicated for simplification or convenience. Furthermore, the parts of each structure in the drawings will be described separately. It is worth noting that the elements not shown in the drawings or not described in words are in a form known to ordinary technicians in the relevant technical field.

[0029] The description of the embodiments herein and any reference to directions and orientations are only for the convenience of description and are not to be construed as any limitation on the scope of protection of the present invention. The following description of the preferred embodiments may involve combinations of features, which may exist independently or in combination, and the present invention is not particularly limited to the preferred embodiments. The scope of the present invention is defined by the claims.

[0030] like Figure 1 and Figure 2As shown, the utility model proposes a cigarette cartridge, including a cigarette cartridge body 1, the cigarette cartridge body 1 is provided with an inner cavity 2 for filling tobacco, one end of the cigarette cartridge body 1 is provided with a head 3, and the other end is an open end 4, the connection between the cigarette cartridge body 1 and the head 3 is a rounded structure 5, the head 3 includes an outer ring connecting part 31 and an inner ring heating part 32, the inner ring heating part 32 is recessed toward the inner side of the cigarette cartridge body 1, and a plurality of micro through holes 6 are provided on the inner ring heating part 32.

[0031] The cigarette cartridge is used in conjunction with an electronic cigarette device or other heating device. The cigarette cartridge includes a cigarette cartridge body 1 and an inner cavity 2 in the cigarette cartridge body 1. The inner cavity 2 is used to fill tobacco. A sealing head 3 is provided at one end of the cigarette cartridge body 1, and the other end is provided as an opening. The sealing head 3 and the cigarette cartridge body 1 can be integrally formed for easy processing. During use, the sealing head 3 contacts the heating part, and the tobacco in the inner cavity 2 is heated by the heat conduction of the sealing head 3, and the smoke generated by evaporation overflows through the opening end 4.

[0032] By recessing the inner ring heating portion 32 of the seal 3 toward the inside of the cartridge body 1, a convection cavity is formed between the seal 3 and the heating portion, which can effectively avoid the problem of blockage of the micro-through holes 6 caused by complete fitting, thereby improving the heating efficiency, facilitating the rapid increase in the temperature of the inner cavity 2 of the cartridge, improving the heating efficiency, and also improving the battery life of the electronic cigarette device or other heating device.

[0033] The cigarette cartridge body 1 is made of metal material and can be manufactured in one piece, which is easy to produce. During the heating process, the inner circle heating part 32 and the side wall of the cigarette cartridge body 1 can quickly conduct heat, thereby improving the heating rate and uniformity of the unit tobacco, achieving the purpose of quickly increasing the temperature inside the cigarette cartridge, and further improving the utilization rate of the tobacco material.

[0034] One end of the cartridge body 1 is provided with a sealing head 3, and the other end is set as an opening, so that the smoke generated by the tobacco in the cartridge can quickly overflow through the opening end 4, so as to achieve the purpose of quickly heating the smoke, ensure the smoke concentration, and improve the user experience.

[0035] The direction of the cigarette cartridge can be identified through the depression of the inner ring heating part 32 toward the inner side of the cigarette cartridge body 1, and there is no need to set a limit on the outer side of the side wall of the cigarette cartridge, thereby avoiding the limit of the cigarette cartridge installation chamber scratching the cigarette cartridge.

[0036] The connection between the cigarette cartridge body 1 and the sealing head 3 is a rounded structure 5, which is conducive to the rapid assembly of the cigarette cartridge.

[0037] It is understandable that a small amount of gel can be applied to the micro through holes 6 of the cigarette cartridge, and the taste of the smoke produced by the tobacco can be adjusted by adjusting the smell of the gel to enhance the user experience.

[0038] In some embodiments of the present invention, the inner ring heating portion 32 is recessed to a depth of 0.1 to 0.5 mm toward the inner side of the cigarette cartridge body 1 .

[0039] The gap between the inner ring heating part 32 of the head 3 and the heating part of the electronic cigarette device or other heating type device is crucial. If the gap size is too large, the heat conduction will be slow, and if the gap size is too small, the heat radiation and hot air flow will be poor, resulting in excessive local temperature. When the depth of the inner ring heating part 32 recessed to the inner side of the cartridge body 1 is 0.1 to 0.5 mm, the optimal heating efficiency is achieved, while the cartridge strength can be met and installation is also convenient.

[0040] The working temperature for evaporation of the active ingredients of tobacco is between 160°C and 260°C. Based on this, 180°C is taken as the standard. The following is an explanation based on the specific data in Table 1, wherein time t refers to the time required for the temperature inside the cartridge to reach 180°C from room temperature (20°C), and depth D refers to the depth of the inner circle heating part 32 recessed toward the inner side of the cartridge body 1.

[0042] Table 1

[0043] In some embodiments of the utility model, the cartridge body 1 is cylindrical, the side wall thickness is 0.1-0.5 mm, and the diameter of the inner cavity 2 is 5-15 mm, which can meet the intensity of the cartridge and improve the heating efficiency.

[0044] In some embodiments of the utility model, the mass of tobacco filled in the inner cavity 2 is 0.2-0.5 g, which can be fully atomized during preheating and use to avoid waste, and there is usually no surplus during use.

[0045] In some embodiments of the present invention, a plurality of micro through holes 6 are distributed in an array on the inner ring heating portion 32, and the number of the micro through holes 6 is not less than 8. Figure 3 As shown, the number of micro through holes 6 is 13. Figure 4 As shown, the number of micro through holes 6 is 32.

[0046] In some embodiments of the present invention, the diameter of the micro through hole 6 is 0.5-1 mm, which is beneficial to improving the heat conduction efficiency.

[0047] In some embodiments of the utility model, the thermal conductivity of the cartridge body 1 is greater than 200, which is conducive to quickly, evenly and efficiently transferring the heat of the heating part of the electronic cigarette device or other heating device to the tobacco through the cartridge body 1, so that it can play its role.

[0048] For example, the cigarette cartridge body 1 is made of aluminum material with a thermal conductivity of 217, and can be recycled or reused after use.

[0049] In some embodiments of the present invention, the particle size of the tobacco filled in the inner cavity 2 is 1 mm to 1.5 mm.

[0050] In some embodiments of the utility model, the opening end 4 is sealed with a plastic plug or aluminum foil, which can protect the broken tobacco from falling out during the packaging process, while reducing the contact between the broken tobacco and the air, thereby extending the shelf life of the tobacco. In addition, the sealed cigarette cartridge can also be placed in a capsule-type package with a film attached to the back to fully seal it, so as to isolate the air to the maximum extent and protect the cigarette cartridge.

[0051] The serial numbers of the above-mentioned steps involved in the method of the utility model do not mean the order of execution of the method. The execution order of each step should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the implementation method of the utility model.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
