Description

Technical Field

[0001] This utility model particularly relates to a non-contact heating non-combustion device. Background Technology

[0002] In recent years, heated tobacco products have received widespread attention due to their ability to reduce the release of harmful substances. These devices precisely heat tobacco materials to a specific temperature (typically around 300-350°C), causing them to release nicotine and flavor compounds without combustion, thus producing an inhalable aerosol. Non-contact heating technology, in particular, has significant advantages because it avoids direct contact with the cigarette: it reduces contamination of the heating element and improves heating uniformity.

[0003] Existing non-contact heated tobacco products typically employ a heating element installed within the device itself, indirectly heating the cigarette by heating the air inside the storage cavity. While this method avoids the cigarette sticking problem associated with traditional contact heating, it still faces several technical bottlenecks in practical applications. In particular, the installation method of the heating element currently often uses a closed, fixed structure, embedding the heating element inside the device body. Although this design ensures the integrity and aesthetics of the device, it introduces significant maintenance challenges.

[0004] Because condensate and tar residue are inevitably produced during the heating process of tobacco materials, these substances gradually accumulate in the gap between the heating element and the device body over long-term use. This accumulation leads to multiple problems: First, the residue reduces heating efficiency and affects the accuracy of temperature control; second, the accumulated tar may carbonize and produce an off-flavor, affecting the taste and quality of the aerosol; third, the enclosed structure makes thorough cleaning difficult for users, which not only shortens the lifespan of the device but may also breed bacteria, posing a hygiene hazard. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a non-contact heating non-combustible device.

[0006] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0025] The working principle of this utility model is as follows:

[0026] The device body 1 of this utility model is rectangular in shape, with an internal storage cavity for holding cigarettes 6. An installation groove is provided on the device body 1, with a lower fixing seat 3 fixed at the bottom of the groove and an upper fixing seat 4 movably positioned along the groove edge. The heating element 2 is a hollow cylindrical electric heating plate, with its two ends detachably abutting against the lower fixing seat 3 and the upper fixing seat 4, respectively. When installing the heating element 2, first remove the cover plate 5 on the device body 1. At this time, the upper fixing seat 4 can be manually lifted. Place the two ends of the heating element 2 in the corresponding installation positions on the lower fixing seat 3 and the upper fixing seat 4, respectively. Then, install the cover plate 5, which presses against the upper fixing seat 4, firmly clamping and fixing the two ends of the heating element 2 between the lower fixing seat 3 and the upper fixing seat 4, thus completing the installation. The hollow portion of the heating element 2 forms a heating channel 21, the inner diameter of which is slightly larger than the outer diameter of the cigarette 6. This ensures that the outer surface of the cigarette 6 maintains a suitable non-contact heat conduction distance from the inner wall of the heating element 2. This detachable installation structure makes it easy to disassemble the heating element 2, facilitating regular cleaning and maintenance of the heating element 2 and the inside of the equipment. This effectively avoids various problems caused by the accumulation of residues, extends the service life of the equipment, improves hygiene and safety, and ensures heating efficiency and the taste quality of the aerosol. The lower fixing seat 3, upper fixing seat 4, cover plate 5, and heating element 2 together form the storage cavity for accommodating the cigarette 6.

[0027] Both the upper fixed seat 4 and the lower fixed seat 3 are provided with axially extending guide channels 31. These guide channels 31 are coaxially aligned with the hollow part of the heating element 2, forming a continuous channel for the cigarette 6 to pass through. The inner diameter of the guide channel 31 is also adapted to the outer diameter of the cigarette 6, which is used to guide the cigarette 6 to be smoothly inserted into the storage cavity, ensuring that the cigarette 6 is in the correct position during the heating process.

[0028] The device body 1 is also equipped with a rotatable and closable cover 7, which is connected to the device body 1 via a pivoting mechanism. The pivoting mechanism includes a base portion 81 and a pivot portion 82. The base portion 81 is fixed to the device body 1, and a mounting portion 83 extending from one side is embedded in a mounting groove and abuts against the upper fixed seat 4. When the cover plate 5 is installed, the cover plate 5 presses against the fixed mounting portion 83 and simultaneously applies a vertically downward clamping force to the upper fixed seat 4, further ensuring the stable clamping of the heating element 2 by the upper fixed seat 4. Moreover, the structure is compact, small, and easy to carry.

[0029] A pivot cavity 811 is provided on the base portion 81, and a guide groove 812 is provided on the inner wall of the pivot cavity 811. The pivot portion 82 is connected to the sealing cover 7, and a limiting portion 813 that cooperates with the guide groove 812 is provided on its outer periphery. When the sealing cover 7 is rotated, the pivot portion 82 rotates in the pivot cavity 811, and the limiting portion 813 slides along the guide groove 812 to prevent the pivot portion 82 from dislodging from the guide groove 812, thereby ensuring the reliability of the connection between the sealing cover 7 and the equipment body 1 and avoiding the sealing cover 7 from becoming unusable due to the pivot portion 82 dislodging.

[0030] In actual use, rotate the sealing cap 7 to the open position, insert the cigarette 6 into the storage cavity along the guide channel 31, so that the cigarette 6 passes through the heating channel 21 of the heating element 2. Turn on the power, and the heating element 2 starts to work, heating the cigarette 6 non-contactly to produce smoke for the user to inhale. After use, rotate the sealing cap 7 to the closed position of the storage cavity to effectively prevent dust from falling into the storage cavity.

[0031] The non-contact heating non-combustible device of this application features a heating element 2 with its two ends detachably abutting against the lower fixed base 3 and the upper fixed base 4, respectively. Combined with a removable cover plate 5, users can easily disassemble the heating element 2, facilitating regular cleaning and maintenance of the heating element 2 and the internal components of the device. This effectively prevents the accumulation of condensate and tar residues, solving the problems of cleaning difficulties, hygiene hazards, and shortened equipment lifespan caused by the closed structure in existing technologies. The heating element 2 has a hollow cylindrical structure, forming a heating channel 21 through which the cigarette stick 6 passes. Its inner diameter matches the outer diameter of the cigarette stick 6, maintaining a non-contact heat conduction distance between the outer surface of the cigarette stick 6 and the inner wall of the heating element 2. This design avoids the problem of cigarette stick 6 sticking together in traditional contact heating, and compared to existing non-contact indirect air heating methods, it heats the cigarette stick 6 more directly and efficiently, improving heating efficiency and ensuring consistent heating effect. By improving the structure and installation method of heating element 2, the accumulation and carbonization of tar residue in the heating area are avoided, and the generation of odor is reduced, thereby ensuring the taste quality of the aerosol and improving the user's vaping experience.

[0032] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
