The invention relates to a fastener for a heating element of a heating non-combustible smoking article.
The fastener of the heating element of the non-combustion smoking set comprises a spring part 4, a heating element 1, a heating element base 2, a heating cavity 3, a spring support sleeve 5, a sealing rubber ring 6 and a buckle type spring flip cover 7;
the bottom of the heating cavity 3 is sequentially provided with a spring part 4, a spring support sleeve 5 and a sealing rubber ring 6 from top to bottom; the spring part 4, the spring support sleeve 5 and the sealing rubber ring 6 are sleeved on the outer surface of the heating element base 2; the heating element 1 is fixed on the heating element base 2, inserted into the heating cavity 3 from the bottom of the heating cavity 3, and fixed by a snap-in spring flip 7 at the bottom of the heating non-combustible smoking set.
The respective components will be described in detail below.
According to the invention, the heating element 1 is a cone, which has an electromagnetic induction heating effect, the main function of which is to convert electrical energy into thermal energy. The basic reason for the conical shape of the heating element 1 is that the heating area is more uniform, the cartridge is more convenient to insert and use, and is less prone to damage. Its ratio of bottom diameter to height is 1: 6-9. In the present invention, if the ratio of diameter to height is greater than 1: 6, it would make it more difficult to insert the heating element into the heated cartridge; if the diameter to height ratio is less than 1: 9, the heating area of the smoke cartridge is small, and the smoke amount is insufficient; thus, the ratio of diameter to height is 1: 6 to 9 are suitable; preferably 1: 7 to 8.
According to the invention, the heating element base 2 mainly functions to fix and support the heating element, and is composed of a plurality of sections of cylinders with different diameters, and the ratio of the diameter of the upper bottom, the diameter of the middle part and the diameter of the lower bottom to the height is 1: 13.8-14.6, 1: 14.8-15.6, 1: 11.4 to 12.2.
In the present invention, when the ratios of the middle diameter, the lower bottom diameter and the height are within the ranges, respectively, if the ratio of the upper bottom diameter to the height thereof is more than 1: 13.8, the ventilation flow in the heating cavity is small, and the suction feeling is influenced; if its upper base diameter to height ratio is less than 1: 14.6, the difficulty of connecting the heating element with the base is increased; thus, its upper base diameter to height ratio is 1: 13.8 to 14.6 are suitable; preferably 1: 14.2.
likewise, if the ratio of the diameter of the middle portion to the height thereof is greater than 1: 14.8, the heating element base is affected to penetrate through the spring member; if its ratio of the middle diameter to the height is less than 1: 15.6, the stress range of the heating element base can be reduced, and the heating element base is easy to deform; thus, its ratio of the diameter to the height of the middle part is 1: 14.8-15.6 is reasonable; preferably 1: 15.2.
when the ratio of the diameter of the upper bottom to the diameter of the middle part to the height is within the range, if the ratio of the diameter of the lower bottom to the height is more than 1: 11.4, the ventilation flow in the heating cavity is small, and the suction feeling is influenced; if its lower base diameter to height ratio is less than 1: 12.2, the lower part of the base can not be abutted against the position of the fixed spring part; thus, its lower base diameter to height ratio is 1: 11.4 to 12.2 are suitable; preferably 1: 11.7.
in the present invention, the heating element base 2 is made of PEEK material.
According to the invention, the heating chamber 3, which has the basic function of accommodating and fixing the heating cartridge, the heating element 1 and the like, has the functions of providing a flue gas flow channel and supporting a peripheral coil and the like, has an intracavity shape consisting of a plurality of sections of cylinders with different diameters, and the ratio of the diameter of the upper bottom, the diameter of the middle part and the diameter of the lower bottom to the height is 1: 9.5-10.5, 1: 35.5-37.0, 1: 12.5 to 13.5.
In the present invention, when the ratios of the middle diameter, the lower bottom diameter and the height are within the ranges, respectively, if the ratio of the upper bottom diameter to the height thereof is more than 1: 9.5, the design of the whole airflow channel of the smoking set is influenced, and the matched smoke cartridge is easy to loosen after being inserted; if its upper base diameter to height ratio is less than 1: 10.5, the matched cigarette cartridge cannot be inserted into the heating cavity; thus, its upper base diameter to height ratio is 1: 9.5 to 10.5 are appropriate; preferably 1: 10.4.
likewise, if the ratio of the diameter of the middle portion to the height thereof is greater than 1: 35.5, the insertion position of the cigarette cartridge can be changed; if its ratio of the middle diameter to the height is less than 1: 37.0, the design of the airflow channel in the heating cavity of the smoking set is influenced; thus, its ratio of the diameter to the height of the middle part is 1: 35.5 to 37.0 is preferable; preferably 1: 36.8.
likewise, if its ratio of the diameter of the lower base to the height is greater than 1: 12.5, the position of the heating element is changed; if its lower base diameter to height ratio is less than 1: 13.5, the matched parts such as the spring part and the like cannot be installed; thus, its ratio of lower base diameter to height is 1: 12.5 to 13.5 are suitable; preferably 1: 13.2.
according to the invention, the spring element 4 has the essential function of providing an elastic force by compressing the spring element; it is a compression spring shaped to match the profile of the heating element base 2 and has a length in the range of 15 to 20mm, preferably 18 mm. The compression springs used in the present invention are products currently on the market.
According to the invention, the main function of the spring support 5 is to fix the spring position and to transmit the force of the compression spring so that the heating element and the base can be ejected out of the heating chamber. The spring support sleeve is a sleeve with the shape matched with the shape of the heating element 1, a circle of circular ring is arranged on the outer wall of the bottom end of the spring support sleeve 5, and the outer diameter of the circular ring is the same as that of the spring part 4.
The spring support sleeve 5 is made of PEEK polyetheretherketone material, PC + ABS polycarbonate + acrylonitrile-butadiene-styrene copolymer material, PFA perfluoroalkoxy vinyl ether copolymer material or ceramic material. The PEEK, PC + ABS, PFA materials or ceramic materials used in the present invention are commercially available products, such as PEEK material sold under the trade name of PEEK by Noplec technologies, Inc. of Jiangyin, PC + ABS material sold under the trade name of PC + ABS material by Yuanhong plastics insulation materials, Inc. of Dongguan, PFA material sold under the trade name of PFA material by Hengxin plastics materials, Inc. of Dongguan, and ceramic material sold under the trade name of custom-made ceramic part by Mingxin Polymer technologies, Inc. of Shenzhen.
According to the invention, the sealing rubber ring 6 mainly has the function of sealing the environment at the bottom of the heating cavity and buffering the acting force between the bottom of the heating cavity and the spring support sleeve. It is placed between the bottom of the heating chamber 3 and the spring support sleeve 5, and its sealing rubber ring 6 allows the middle and upper parts of the heating element base 2 to pass through.
According to the invention, the snap-in spring flip 7 is a cover with a torsion spring structure, and the heating element and the base can be fixed in the heating cavity by pressing the snap on the cover plate. The cover plate is slid to release the buckle, and the cover plate is turned over under the action of the torsion spring structure, so that the heating element and the base are popped out under the action of the spring part 4. The snap-in spring flip 7 used in the present invention is a product currently marketed, for example, by Shenzhen New dazzling technology Limited under the trade name custom spring flip cover.
[ advantageous effects ]
