Abstract
Description
Technical Field
[0001] This utility model relates to the field of novel tobacco product technology, and in particular to a filter-free heated cigarette device based on spiral airflow cooling. Background Technology
[0002] Traditional heated cigarettes require cellulose acetate filters, which result in smoke loss of up to 30% due to their high retention rate. Furthermore, because the smoke from heated cigarettes is at a high temperature after heating, the relatively short overall length of traditional devices leads to only moderate cooling. To improve cooling, traditional devices often increase the volume of the cooling section, resulting in the cooling section accounting for over 40% of the device's length. This makes the devices less portable, and the accumulation of condensate severely impacts aerosol transport efficiency. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will be further described below with reference to the accompanying drawings, wherein:

[0026] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0027] This utility model proposes an embodiment of a filter-free heated cigarette smoking device based on spiral airflow cooling. Specifically, as follows: Figures 1 to 2 As shown, it includes:
[0028] Smoking accessory casing 1;
[0029] A heating chamber 2 is located at the first end of the outer casing 1 of the smoking device;
[0030] A heating element 21 is fixed inside the heating chamber 2;
[0031] A mouthpiece 3 is located at the second end of the outer casing 1 of the smoking device;
[0032] A spiral cooling module is fixedly connected at both ends to the heating chamber 2 and the mouthpiece 3 respectively, and the interior of the spiral cooling module is connected to the heating chamber 2 and the mouthpiece 3 respectively.
[0033] The heated cigarette device in this embodiment mainly includes a heating chamber 2, a spiral cooling module, and a mouthpiece 3 connected in sequence. The heating chamber 2, the spiral cooling module, and the mouthpiece 3 are all located inside the outer shell 1 of the device. An opening 22 is provided at the first end of the heating chamber 2, through which a cigarette is inserted. A heating element 21 is fixed inside the heating chamber 2. The end of the heating element 21 has a needle-like structure, allowing it to be inserted into the cigarette. The bottom of the heating element 21 is electrically connected to a heating circuit, providing heat to the heating element 21, thereby heating the tobacco in the cigarette and generating smoke.
[0034] The spiral cooling module includes a cooling chamber 41, the first end of which is connected to the heating chamber 2. A spiral tube 42 is installed inside the cooling chamber 41. Multiple first through holes 43 are opened at the second end of the cooling chamber 41, through which the spiral tube 42 is connected to the mouthpiece 3. Multiple second through holes 23 are provided at the connection between the cooling chamber 41 and the heating chamber 2, through which the spiral tube 42 is connected to the heating chamber 2.
[0035] The flue gas generated after being heated in the heating chamber 2 enters the spiral tube 42 of the cooling chamber 41. The spiral structure increases the flow path of the flue gas and the time for the flue gas to enter the mouthpiece 3, so that the flue gas can have a longer cooling and heat dissipation time in the cooling chamber 41, thereby reducing the temperature of the flue gas.
[0036] Meanwhile, multiple turbulence protrusions are set inside the spiral tube 42 to further increase the resistance to flue gas flow, increase the flow time of flue gas in the spiral tube 42, and further improve the cooling effect.
[0037] Optionally, since the heating chamber 2 and the mouthpiece 3 are only connected to the spiral tube 42, and the cooling chamber 41 is a completely sealed structure, cooling materials such as coolant or cooling particles can be installed in the cooling chamber 41 to ensure that the flue gas can be cooled to a suitable temperature.
[0038] In this embodiment, the spiral tube 42 is a tapered conical spiral tube made of medical-grade 316L material (wall thickness 0.3mm, thermal conductivity 16.3W / m·K). The turbulence protrusions are set with a height of 0.1mm and a spacing of 0.5mm. Through the spiral tube 42, the flue gas temperature drops from 120℃ to 48℃ at a flow rate of 50ml / s, achieving a flue gas volume compression ratio of 1:1.2.
[0039] Next, the cooled smoke enters the mouthpiece 3. The cigarette does not require a filter rod, and the user can directly inhale through the mouthpiece. Compared with traditional filter-type cigarettes, the smoke concentration is increased, the total particulate matter transfer is increased by 42%, and the retention rate of effective smoke components is increased to 92%. Furthermore, the filter rod assembly process is eliminated, reducing manufacturing costs by 37%.
[0040] The heated cigarette device in this embodiment is compatible with filterless cigarettes with a diameter of 5.4-5.8mm and a length of 35-45mm, which can effectively improve the cooling effect and enhance the consumer's smoking experience.
[0041] In this embodiment of the invention, any use of terms expressing location is based on a relative concept of the embodiment. Furthermore, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent the existence of A alone, A and B simultaneously, or B alone. A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" and similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, and c can represent: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, and c can be single or multiple.
