[0008] In the Z direction, the cover is provided with a first air hole.

[0009] In one embodiment, the cover includes:

[0010] A first conical cylinder, movably covered within the opening, has, in the Z direction, a small-diameter end facing the heating element and a large-diameter end away from the heating element; and

[0011] A sealing portion is connected to the small-diameter end; one of the sealing portions is located on one side of the heating tube along the Z direction, and the other sealing portion is located on the other side of the heating tube along the Z direction. The two sealing portions and the heating chamber enclose the cavity.

[0012] In the Z direction, the first vent is disposed through the cap portion.

[0013] In one embodiment, the dry-burning equipment further includes two mounting parts, which are respectively located on both sides of the housing in the Z direction;

[0014] The side of the first cone away from the cover is connected to the mounting part, and the mounting part is movably connected to the housing so that the cover has a cover position covering the opening and an open position away from the opening.

[0015] In one embodiment, the mounting portion has a cavity, and the cavity communicates with the outside on the side facing the corresponding cover, so that the space inside the first cone and the cavity enclose and form an air passage for airflow movement;

[0016] One of the mounting parts has a suction nozzle on the side away from the cover, and the suction nozzle is connected to the air passage; the other mounting part has a second air hole on the side away from the corresponding cover, which is connected to the air passage and the outside.

[0017] In one embodiment, the cover further includes an extension connected to the periphery of the end of the first cone away from the sealing portion;

[0018] In the Z direction, the extension extends away from the cover portion, and the first cone is fixedly connected to the mounting portion via the extension.

[0019] In one embodiment, the dry-burning device further includes a second cone, having two cones, which are respectively connected to both sides of the housing along the Z-direction;

[0020] In the Z direction, both ends of the second cone are open, so that the space inside the second cone forms the opening.

[0021] In one embodiment, the dry-burning equipment further includes:

[0022] The first magnetic clamp is held between the mounting portion and the extension portion; and

[0023] The second magnetic attractor is disposed on the side of the second cone opposite to the first magnetic attractor. In the Z direction, the first magnetic attractor and the second magnetic attractor are respectively disposed.

[0024] In one embodiment, the dry-burning equipment further includes a heat insulation cylinder disposed within the housing;

[0025] In the Z direction, the heating element is located inside the heat insulation cylinder, and the heat insulation cylinder and the heating element are spaced apart.

[0026] The second magnetic clamp is held between the second cone and the heat insulation cylinder.

[0027] In one embodiment, the space between the heat insulation cylinder and the heating tube forms a heat insulation cavity, and the dry-burning device further includes two sealing rings.

[0028] In the Z direction, the two sealing rings are respectively disposed on both sides of the heat insulation cavity, with the outer peripheral side of the sealing ring fitting against the inner wall of the heat insulation cylinder and the inner peripheral side of the sealing ring fitting against the heating tube.

[0029] In one embodiment, the heating element includes:

[0030] Insulating structural member, the insulating structural member being arranged in a tubular shape; and

[0031] The heating wire is located on the outer periphery of the insulating structure.

[0032] This utility model of dry-burning equipment features openings on both sides of the casing, with a cover movably mounted on the casing to cover these openings. During use, the cover seals both ends of the heating chamber, allowing tobacco leaves to be stored inside. When cleaning is required, the cover is opened, opening both ends of the heating chamber. This allows for cleaning of residues produced after tobacco combustion through both openings, significantly improving cleaning convenience compared to cleaning only from one end. Because cleaning can be performed from both ends of the heating chamber, the residues are cleaned more thoroughly, maintaining a relatively clean environment after each use, preventing odors, and improving the user experience.

[0058] Dry burning of tobacco products is a technology that uses a specific heating method to produce smoke by incompletely burning tobacco or tobacco materials. This technology aims to reduce the harmful substances produced by traditional combustion methods while providing a safer and healthier smoking experience. After the tobacco leaves are heated, residue will be produced, which needs to be cleaned. Current dry burning equipment usually only has one opening, making it inconvenient to clean the residue in the heating chamber. Incomplete cleaning will produce odors when smoking, reducing the user experience.

[0059] Based on this, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this application provides a dry-burning device with a Z-direction extending along its height, including a housing 1, a heating element 2, and a cover 3. The housing 1 has openings 11 on both sides of the Z-direction. The heating element 2 is disposed inside the housing 1 and arranged along the Z-direction. Both ends of the heating element 2 along the Z-direction are open and correspond to the positions of the openings 11 on both sides of the housing 1 along the Z-direction. The space inside the heating element 2 forms a heating chamber 23 for heating tobacco leaves. When the heating element 2 is energized, it generates heat, thereby causing the tobacco leaves in the heating chamber 23 to dry-burn. That is, the tobacco leaves are incompletely burned in the heating chamber 23 to produce smoke, which is then inhaled by the user. This method can significantly reduce the harmful substances produced by traditional combustion methods and provide a safer and healthier smoking experience.

[0060] In this embodiment, the dry-burning device also includes two covers 3, and there are two covers 3, which are respectively located at both ends of the housing 1 along the Z direction. In the Z direction, the position of the cover 3 is opposite to the position of the opening 11, and the cover 3 is movably covered at the corresponding opening 11. Thus, the two covers 3 can seal both ends of the heating chamber 23 along the Z direction, and make the heating chamber 23 form a relatively closed cavity, which is used to store tobacco leaves in the cavity and prevent the tobacco leaves from falling out of the heating chamber 23.

[0061] It is understandable that, such as Figure 3 , Figure 4 As shown, two covers 3 are provided with first air holes 321 extending along the Z direction. There can be multiple first air holes 321, which are evenly distributed on the covers 3. The first air holes 321 are used for air inflow and smoke exhaust. In actual use, air enters the heating chamber 23 from the multiple first air holes 321 on the lower cover 3 and flows through the tobacco leaves, carrying away the smoke generated when the tobacco leaves are dry-burned. Finally, it is exhausted outward from the multiple first air holes 321 on the upper cover 3. In the Z direction, the two covers 3 are correspondingly arranged and are both positioned with the heating chamber 23. This allows air to enter the heating chamber 23 from the lower first air hole 321 and then be smoothly exhausted outward from the upper first air hole 321, preventing smoke from accumulating in the heating chamber 23.

[0062] In this embodiment, when the user needs to clean the residue inside the heating chamber 23, the cover 3 can be opened, so that the two openings 11 are open. The user can use tools (such as a small brush, tweezers, etc.) to reach into the heating chamber 23 from the top and bottom ends of the shell 1 to clean it. It can be understood that through the two openings 11, the user can clean from different angles to ensure that every corner inside the heating chamber 23 can be cleaned. This design can remove residue more thoroughly. Compared with only one opening 11, this design makes cleaning more convenient and thorough, and can more effectively remove residue inside the heating chamber 23. This thorough cleaning of residue inside the heating chamber 23 can avoid odor caused by residue, thereby improving the user experience.

[0063] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, in one embodiment of this application, the cover 3 includes a first conical cylinder 31 and a sealing portion 32; wherein, the first conical cylinder 31 is movably covered at the opening 11, and in the Z direction, the first conical cylinder 31 has a small-diameter end 312 facing the heating tube 2 and a large-diameter end 311 away from the heating tube 2; the sealing portion 32 is connected to the small-diameter end 312, thereby realizing that when the first conical cylinder 31 is covered in the opening 11, the sealing portion 32 connected to one side of the small-diameter end 312 of the first conical cylinder 31 is just located at both ends of the heating tube 2 in the Z direction, thereby realizing that the heating chamber 23 inside the heating tube 2 is enclosed into the cavity for storing tobacco leaves by the two sealing portions 32; as Figure 3 , Figure 4 As shown, a first air hole 321 in the Z direction is provided through the cover part 32, so that outside air enters into the heating chamber 23 through the first air hole 321 on the lower cover part 32, and the smoke generated by the dry burning of tobacco leaves is discharged outward through the first air hole 321 on the upper cover part 32.

[0064] It is understandable that the first conical cylinder 31 constituting the cover 3 is conical, and the small-diameter end 312 of the first conical cylinder 31 faces the heating tube 2. As a result, the openings 11 on both sides of the housing 1 along the Z direction are also conical. That is, the cross-sectional dimension of the end of the opening 11 facing the heating tube 2 is smaller than the cross-sectional dimension of the end of the opening 11 away from the heating tube 2, making the opening 11 also a conical hole structure. This design makes it convenient for users to clean the residue on the wall of the heating chamber 23 from the outside at different angles using cleaning tools. Since the cross-sectional dimension of the end of the opening 11 away from the heating chamber 23 is larger, it allows users to insert cleaning tools from multiple directions, ensuring that every corner of the inner wall of the heating chamber 23 can be cleaned. The larger diameter of the end of the opening 11 away from the heating chamber 23 can accommodate cleaning tools of different shapes and sizes, improving the flexibility and efficiency of cleaning.

[0065] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, in one embodiment of this application, the dry-burning device further includes a mounting part 4, of which there are two. In the Z direction, the two mounting parts 4 are respectively disposed on both sides of the housing 1; it can be understood that each mounting part 4 corresponds to a cover 3; as Figure 5 As shown, the end of the first cone 31 furthest from the cap 32 is fixedly connected to the corresponding mounting part 4, as... Figure 3 , Figure 4 As shown, one mounting part 4 is movably connected to one side of the housing 1 along the Z direction, and the other mounting part 4 is movably connected to the other side of the housing 1 along the Z direction. This allows the mounting part 4 to be adjusted and the cover 3 to seal the openings 11 on both sides of the housing 1 along the Z direction when it is necessary to cover them (e.g., ...). Figure 3 As shown, when it is necessary to open the housing 1 on both sides along the Z direction, the position of the mounting part 4 is adjusted and the cover 3 is moved away from the opening 11, thereby opening the opening 11.

[0066] In this embodiment, the movable connection between the mounting part 4 and the housing 1 can be a hinge, such as... Figure 3 , Figure 4 As shown, by providing a hinge shaft on the housing 1, the mounting part 4 is rotatably mounted on the housing 1. By adjusting the angle of the mounting part 4 relative to the housing 1, the position of the cover 3 connected to the mounting part 4 is achieved, and it is positioned in the open position (e.g., Figure 4 (as shown) and capping position (as shown) Figure 3 Switch and adjust between (as shown).

[0067] It is understandable that, in order to facilitate the positioning of the mounting part 4 at its angle, a friction damping ring can be provided on the hinge shaft between the mounting part 4 and the housing 1. This increases the damping force when the mounting part 4 rotates relative to the housing 1, thereby ensuring that when the mounting part 4 drives the cover 3 to the open position and cleans the residue in the heating chamber 23, the mounting part 4 can be stably maintained in the current position, that is, the cover 3 can be stably kept in the open position, ensuring that the cover 3 will not easily shake during the cleaning process, so as not to affect the cleaning operation.

[0068] Reference Figure 3 , Figure 4 , Figure 6 , Figure 8 As shown, in one embodiment of this application, the mounting part 4 has a cavity 41, and the cavity 41 communicates with the outside on the side facing the corresponding cover 3, so that the space inside the first cone 31 and the cavity 41 enclose and form an air passage 5 for airflow movement; as Figure 3As shown, when outside air enters from the lower first air intake, it first enters the air passage 5 formed by the cavity 41 and the space inside the first cone 31, and then passes upward through the air passage 5 through the first air hole 321 provided on the cover 32 before finally entering the heating chamber 23. Similarly, the smoke generated by the dry burning of tobacco leaves in the heating chamber 23 first enters from the first air hole 321 on the upper cover 32 into the air passage 5 formed by the space inside the first cone 31 and the cavity 41 inside the mounting part 4, and finally is discharged outward through the air passage 5.

[0069] It is understandable that, such as Figure 3 As shown, a suction nozzle 42 is provided on the side of the mounting part 4 facing away from the cover 3. The suction nozzle 42 can be integrally connected to the mounting part 4. The suction nozzle 42 has a channel communicating with the cavity 41. The user sucks the exhaust gas through the suction nozzle 42; Figure 9 As shown, a plurality of second air holes 43 are provided through the mounting part 4 located below along the Z direction, so that outside air enters into the air passage 5 through the second air holes 43 and is delivered into the heating chamber 23 through the first air hole 321 provided on the cover part 32.

[0070] Reference Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, in one embodiment of this application, the cover 3 further includes an extension 33, which is connected to the periphery of the end of the first cone 31 away from the sealing part 32. That is, the extension 33 is connected to the periphery of the large diameter end 311 of the first cone 31. In the Z direction, the extension 33 extends in a direction away from the sealing part 32 of the housing 1. The first cone 31 is fixedly connected to the mounting part 4 through the extension 33.

[0071] In this embodiment, as Figure 4 , Figure 6 As shown, the extension 33 includes a horizontally arranged first part, a second part extending along the Z direction, and a horizontally arranged third part. The two ends of the second part along the Z direction are connected to the first part and the third part respectively. The end of the first part away from the second part is connected to the circumference of the large-diameter end 311 of the first cone 31. The third part is fixedly connected to the mounting part 4, thereby fixing the cover 3 to the mounting part 4. Figure 3 As shown, when the cover 3 is in the sealed position, the first cone 31 and the sealing part 32 are located inside the opening 11, while the extension part 33 is located outside the opening 11. The first part and the two sides of the housing 1 along the Z direction abut and fit together, thereby completely sealing the opening 11 on both sides of the housing 1 along the Z direction. This prevents the smoke generated by the dry burning of tobacco leaves in the heating chamber 23 from leaking out through the gap between the cover 3 and the inner wall of the opening 11, so that the smoke can only be discharged out through the mouthpiece 42, ensuring the user's smoking experience.

[0072] In this embodiment, the extension 33, the first cone 31, and the cap 32 can be an integral structure, such as... Figure 5 , Figure 7 As shown, the extension 33 can be fixedly mounted on the mounting part 4 by screws.

[0073] Reference Figure 4 As shown, in one embodiment of this application, the dry-burning device further includes a second cone 12. There are two second cones 12, which are respectively connected to both sides of the housing 1 along the Z direction (the second cones 12 can be fixedly connected to the housing 1 by snap-fit ​​or fasteners). In the Z direction, both ends of the second cone 12 are open, so that when the second cone 12 is installed on both sides of the housing 1 along the Z direction, the space inside the second cone 12 forms the above-mentioned opening 11. Specifically, the outline of the second cone 12 should match the outline of the first cone 31 so that the first cone 31 can be covered inside the second cone 12 as the position of the mounting part 4 is adjusted.

[0074] Understandably, in order for the first cone 31 to move out of or into the second cone 12 as the position of the mounting part 4 is adjusted, the cross-sectional dimension of the second cone 12 should be slightly larger than that of the first cone 31. This is because the first cone 31 does not directly enter the second cone 12 along the Z-direction, but rather enters the second cone 12 as the mounting part 4 rotates relative to the housing 1. Therefore, the cross-sectional dimension of the second cone 12 needs to be set slightly larger than that of the first cone 31 (e.g., ...). Figure 3 As shown), when the first cone 31 is in the capped position, there is still a slight gap between the first cone 31 and the second cone 12, so that the first cone 31 can move out of or into the second cone 12 as the mounting part 4 rotates.

[0075] In this embodiment, although there is a slight gap between the first cone 31 and the second cone 12, the first part arranged horizontally in the extension 33 allows the first part and the two sides of the housing 1 along the Z direction to fit and abut against each other when the cover 3 is in the sealed position. This prevents the smoke generated by the dry burning of tobacco leaves in the heating chamber 23 from leaking out through the gap between the first cone 31 and the second cone 12, so that the smoke can only be discharged out through the mouthpiece 42.

[0076] Reference Figure 3 , Figure 4 As shown in one embodiment of this application, the dry burning device further includes a magnetic suction element 6, which is used to restrict unnecessary movement of the cover 3 relative to the housing 1 when the cover 3 is in the sealed position, so as to prevent the cover 3 from being accidentally opened by the user.

[0077] In this embodiment, there are two magnetic suction components 6, which are used to limit the two covers 3 relative to the shell 1 when they are in the sealed position; wherein the magnetic suction component 6 includes a first magnetic suction component 61 and a second magnetic suction component 62, as shown below. Figure 6 , Figure 8 As shown, both the first magnetic chuck 61 and the second magnetic chuck 62 are arranged in a ring shape; the first magnetic chuck 61 is disposed on the cover 3, and the second magnetic chuck 62 is disposed on the housing 1; as Figure 4 As shown, when the extension 33 is fixedly connected to the mounting part 4, an installation space is formed between the first part, the second part of the extension 33 and the mounting part 4, so that the first magnetic member 61 is accommodated in the installation space. In order to reliably limit the first magnetic member 61, the installation space should be consistent with the size of the first magnetic member 61. Thus, when the extension 33 is fixed to the mounting part 4 by screws, the first magnetic member 61 is also clamped and restricted in the installation space.

[0078] In this embodiment, as Figure 3 , Figure 4 As shown, the second cone 12 also includes a horizontally arranged fourth part and a cone-shaped fifth part, wherein the space inside the fifth part forms the aforementioned opening 11. When the second cone 12 is installed on the housing 1, the horizontally arranged fourth part is flush with both sides of the housing 1 along the Z direction, that is, when the cover 3 is in the sealed position, as... Figure 3 As shown, this ensures that the first part on the extension 33 and the fourth part on the second cone 12 remain in contact and abut against each other; while the second magnetic member 62 is located on the side of the fourth part away from the first part, as shown. Figure 3 As shown, when the second cone 12 is installed on the housing 1, the fourth part and the internal structure of the housing 1 enclose a mounting space for installing the second magnetic member 62, and the size of this mounting space should be consistent with that of the second magnetic member, thereby clamping and confining the second magnetic member 62 within the mounting space; as shown Figure 3 As shown, when the cover 3 is in the closed position, the first magnetic member 61 and the second magnetic member 62 are positioned exactly in tandem, and the magnetic attraction between them is used to stably restrict the cover 3 in the closed position without causing unnecessary shaking. When it is necessary to open the cover 3, the user only needs to rotate the mounting part 4 in the direction away from the housing 1 to overcome the magnetic attraction between the first magnetic member 61 and the second magnetic member 62, and move the cover 3 from the closed position to the open position.

[0079] Reference Figure 3 , Figure 4As shown, in one embodiment of this application, the dry-burning device further includes a heat insulation cylinder 7, which is disposed inside the housing 1; in the Z direction, the heating tube 2 is disposed inside the heat insulation cylinder 7, and the heat insulation cylinder 7 and the heating tube 2 are spaced apart, so that a heat insulation area is formed between the heat insulation cylinder 7 and the heating tube 2, effectively isolating heat, reducing the temperature of the housing 1, reducing heat loss, and reducing power consumption (improving heat utilization rate).

[0080] In this embodiment, the heat insulation cylinder 7 can be made of glass fiber composite material, etc. A certain gap is maintained between the heat insulation cylinder 7 and the heating tube 2 to form a heat insulation area. Since the thermal conductivity of air is low, this gap design can further reduce the heat loss to the outside. The heat insulation cylinder 7 effectively isolates the heat generated by the heating tube 2, avoids the shell 1 from getting too hot, and improves the safety of use. At the same time, the heat insulation area further reduces the heat loss to the outside, improves the heat utilization efficiency, and reduces power consumption.

[0081] In this embodiment, as Figure 10 , Figure 11 As shown, a structure of a heat insulation cylinder 7 is provided, wherein the heat insulation cylinder 7 includes a first cylinder 71 and a second cylinder 72, and the first cylinder 71 and the second cylinder 72 are assembled together to form the heat insulation cylinder 7. It can be understood that the first cylinder 71 and the second cylinder 72 can be connected and fixed together by fasteners, such as bolts; a bolt hole is provided on the side where the first cylinder 71 and the second cylinder 72 are assembled, for fixing the two together by bolts and assembling them to form the heat insulation cylinder 7 structure.

[0082] In this embodiment, as Figure 3 As shown, during installation, the first cylinder 71 and the second cylinder 72 are first fixedly connected together, and then the heat insulation cylinder 7 is installed inside the housing 1. For example, the second cylinder 72 can be fixedly installed inside the housing 1 using fasteners, such as... Figure 11 As shown, a structure for fasteners is provided on the periphery of the second cylinder 72, thereby fixing the heat insulation cylinder 7 inside the shell 1; annular portions 721 are integrally provided at the upper and lower ends of the second cylinder 72 along the Z direction, and the outer diameter of the annular portions 721 is consistent with the outer diameter of the heat insulation cylinder 7; as shown Figure 3 As shown, when the heat insulation cylinder 7 is installed inside the housing 1, an installation space for clamping and restricting the second magnetic suction member 62 is formed in the space between the fourth part of the second cone cylinder 12 and the annular part 721, so that the second magnetic suction member 62 is restricted between the second cone cylinder 12 and the annular part 721, thereby achieving the limiting of the second magnetic suction member 62; as Figure 3 As shown, the fifth part of the second cone 12 is at least partially inserted into the inner side of the annular part 721.

[0083] Reference Figure 3 , Figure 4As shown, in one embodiment of this application, the space between the heat insulation cylinder 7 and the heating tube 2 forms a heat insulation cavity 8. The dry-burning device also includes a sealing ring 9, of which there are two. The two sealing rings 9 are respectively disposed on both sides of the heat insulation cavity 8 along the Z direction. The outer peripheral side of the sealing ring 9 is fitted with the inner wall of the heat insulation cylinder 7, and the inner peripheral side of the sealing ring 9 is fitted with the heating tube 2. Thus, by providing two sealing rings 9, the connection between the heating chamber 23 and the opening 11 is reliably sealed, ensuring that the smoke generated by the tobacco in the heating chamber 23 will not leak through the connection between the opening 11 and the heating chamber 23.

[0084] In this embodiment, an installation structure for positioning the sealing ring 9 is provided, such as... Figure 10 , Figure 11 As shown, a first sub-ring 731 is provided on both sides of the first cylinder 71 along the Z direction, and a second sub-ring 732 is provided on both sides of the second cylinder 72 along the Z direction. When the first cylinder 71 and the second cylinder 72 are assembled to form the heat insulation cylinder 7, the mating first sub-ring 731 and second sub-ring 732 are assembled to form a clamping ring 73 (e.g., Figure 4 As shown), this creates an installation space for installing the sealing ring 9 between the clamping ring 73 and the corresponding annular portion 721, and causes the sealing ring 9 to abut against the annular portion 721 and the clamping ring 73 on both sides along the Z direction, thereby sealing the heating chamber 23 at the joint of the opening 11 at both ends along the Z direction, preventing the flue gas from leaking outward from there.

[0085] Reference Figure 12 As shown, in one embodiment of this application, the heating tube 2 includes an insulating structure 21 and a heating wire 22. The insulating structure 21 is tubular, and its internal space forms the heating chamber 23. The insulating structure 21 can be made of ceramic material and has good insulation performance. The heating wire 22 is provided on the outer periphery of the insulating structure 21. The heating wire 22 is evenly distributed on the outer periphery surface of the insulating structure 21, and a conductive element (conductive wire) is provided at an appropriate position on the outer periphery of the insulating structure 21. The conductive element is used to realize the electrical connection between the heating wire 22 and the external power supply component. When the power supply component supplies power to the heating wire 22 through the conductive element, the heating wire 22 generates heat, thereby heating the tobacco leaves in the heating chamber 23 and causing them to dry burn to produce smoke.

[0086] It is understandable that the heating power of the heating wire 22 can be controlled by controlling the current flowing through the heating wire 22, thereby controlling the amount of heat generated. This allows for temperature control within the heating chamber 23, enabling the tobacco leaves to produce smoke in the heating chamber 23 through dry burning. This reduces harmful substances from traditional combustion methods and provides a safer and healthier smoking experience.

[0087] It is understandable that a power supply component (battery), such as a lithium-ion battery, is provided inside the housing 1 for supplying power to the heating wire 22, and a circuit board is also provided inside the housing 1 for power supply control, etc.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
