[0002] Traditional cigarettes need to be ignited and burned with an open flame to produce tobacco smoke. During the cracking process of tobacco at high temperature, thousands of mixed substances harmful to the human body are released, which are composed of volatile substances in the gas and semi-volatile and non-volatile substances in the particles, such as carbon monoxide, phenols, aldehydes, nicotine (nicotine), tar, etc.

[0003] Low-temperature baked tobacco products (low-temperature cigarettes) can significantly reduce the production of harmful substances and are healthier. Low-temperature cigarettes use surrounding heating and central heating technology when in use. When in use, the user puts the low-temperature cigarette into the low-temperature smoking device, turns on the switch on the low-temperature smoking device, and there is a heating rod in the low-temperature smoking device, which heats the low-temperature cigarette.

[0004] However, the existing heating methods all utilize heat conduction baking methods, which have a relatively low efficiency. Summary of the invention

[0018] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0020] Reference Figure 1 The present application provides a heating element assembly 1, comprising a carrier 1 and a heating element 2; the carrier 1 comprises an inner wall 11, an outer wall 12 and a bottom plate 13, the inner wall 11 and the outer wall 12 are both annular, the outer wall 12 is sleeved on the outside of the inner wall 11, and there is a gap between the inner wall 11 and the outer wall 12, and the gap is a hollow cavity 14; the heating element 2 is arranged in the hollow cavity 14; the inner wall 11 is made of a transparent material, and the cavity formed by the inner annular surface of the inner wall 11 is a heating cavity 15, and the heating cavity 15 is used to place low-temperature tobacco to be baked.

[0021] In this embodiment, the carrier 1 is a device for fixing the heating element 2 and placing low-temperature cigarettes. The cavity between the two annular walls formed by the two annular walls of the carrier 1 after being sleeved is a hollow cavity 14; when the heating body assembly is installed on the shell assembly of the low-temperature smoking device, the bottom of the two annular walls is in contact with the shell assembly, and a hollow cavity 14 is formed between the two annular walls and the shell assembly. In addition, a bottom plate 13 can also be provided on the carrier 1, and the inner wall 11, the outer wall 12 and the bottom plate 13 together form a hollow cavity 14. For example, the carrier 1 is composed of two annular walls and a bottom plate 13, and the two annular walls are the inner wall 11 and the outer wall 12, respectively. Specifically, they can be two cylinders with different diameters, and the diameter of the outer wall 12 is greater than the diameter of the inner wall 11. The inner wall 11 is placed inside the outer wall 12, and the bottom plate 13 is placed under the two cylinders, so that a hollow cavity 14 is formed between the bottom plate 13 and the two annular walls, and a heating element 2 is arranged in the hollow cavity 14. The heating element 2 emits infrared light while generating heat after being powered on, so that the hollow cavity 14 forms a heat radiator. The heating element 2 radiates heat energy into the hollow cavity 14 after passing the inner wall 11 made of transparent material through infrared light, thereby baking and heating the low-temperature smoke in the hollow cavity 14. Specifically, the heating element 2 can be a heating wire. At the same time, the inner annular surface of the inner wall 11 and the bottom plate 13 form a heating cavity 15, and the heating cavity 15 is used to place low-temperature smoke. Since the inner wall 11 is made of a transparent material, the heat emitted by the hollow cavity 14 is radiated to the low-temperature smoke in the heating cavity 15 through the inner wall 11 through infrared light, so that the low-temperature smoke is baked and heated. When the heating element 2 is powered on, it generates heat energy, which penetrates the inner wall 11 made of transparent material of the carrier 1 and radiates to the low-temperature smoke through infrared light, so that the low-temperature smoke is radiated and baked by the infrared light heated by the heating element 2, the baking area is larger, and the heating effect is faster.

[0022] In one embodiment, the heating element is in the shape of an elongated strip and is disposed around the outer annular surface of the inner wall 11 .

[0023] In this embodiment, the heating element is a heating wire in a long strip shape, which surrounds the outer ring surface of the inner wall 11, so that the entire ring of the inner wall 11 is heated, thereby radiating the low-temperature smoke all around at the same time, increasing the heating area and increasing the heating speed.

[0024] In one embodiment, the heat generating element includes a first end and a second end, the first end is fixed to the top of the outer annular surface of the inner wall 11 or the top of the inner annular surface of the outer wall 12, and the second end is connected to the lower half of the hollow cavity 14, and the heat generating element 2 is arranged around the outer annular surface of the inner wall 11.

[0025] In this embodiment, the heating element 2 is arranged in the hollow cavity 14. The heating element 2 is in the shape of an elongated strip, and when it surrounds the outer annular surface of the inner wall 11, it surrounds from the bottom to the top of the inner wall 11. The first end of the heating element 2 is fixed to the top of the outer annular surface of the inner wall 11 or the top of the inner annular surface of the outer wall 12, that is, the first end is fixed to the top; at the same time, the second end is connected to the bottom, that is, the bottom plate 13, or the bottom of the outer annular surface of the inner wall 11. The heating element 2 surrounds the outer annular surface of the inner wall 11, and in the axial direction of the inner wall 11, the heating element 2 can radiate heat to the entire axial direction of the inner wall 11 when heating, so that when the inner wall 11 performs thermal radiation heating on the low-temperature smoke, the corresponding length direction of the entire low-temperature smoke can be heated simultaneously, further increasing the heating area and the heating speed.

[0026] In one embodiment, the outer wall 12 is made of a transparent material, and a reflective material is attached to the outer surface of the outer wall 12 .

[0027] In this embodiment, the light emitted by the heating element 2 is scattered, with a portion of it directly passing through the inner wall 11 and irradiating the low-temperature smoke in the heating chamber 15, and the other portion of it irradiating the outer wall 12; the outer wall 12 is set to a transparent material, and a reflective material is attached to the outer ring surface of the outer wall 12, so that the light emitted by the heating element 2 passes through the outer wall 12 and irradiates the reflective material outside the outer wall 12, and then reflects and passes through the inner wall 11 to irradiate the low-temperature smoke in the heating chamber 15, so that the light of the heating element 2 is more effectively irradiated on the low-temperature smoke, thereby heating the low-temperature smoke more quickly and efficiently. In a specific embodiment, the reflective material is attached to the outer ring surface of the outer wall 12, and the side of the reflective material facing the inner wall 11 is serrated, so that the reflected light is easier to focus, so that the reflected light is more concentrated on the low-temperature smoke, and the reflected light is better used to heat the low-temperature smoke.

[0028] In one embodiment, a reflective material is attached to the inner annular surface of the outer wall 12 .

[0029] In this embodiment, the light emitted by the heating element 2 is scattered, with a portion of it directly passing through the inner wall 11 to illuminate the low-temperature smoke in the heating chamber 15, and the other portion of it irradiating the inner annular surface of the outer wall 12; a reflective material is attached to the inner annular surface of the outer wall 12, so that the light emitted by the heating element 2 passes through the inner annular surface of the outer wall 12 and then reflects and passes through the inner wall 11 to illuminate the low-temperature smoke in the heating chamber 15, so that the light of the heating element 2 is more effectively irradiated on the low-temperature smoke, thereby heating the low-temperature smoke more quickly and efficiently. In a specific embodiment, the reflective material is attached to the inner annular surface of the outer wall 12, and the side of the reflective material facing the inner wall 11 is serrated, so that the reflected light is easier to focus, so that the reflected light is more concentrated on the low-temperature smoke, and the reflected light is better used to heat the low-temperature smoke.

[0030] In one embodiment, the transparent material is tempered glass or quartz glass.

[0031] In this embodiment, tempered glass or quartz glass is used, which is transparent and resistant to high temperatures, so that the light emitted by the heating element 2 can easily penetrate the inner wall 11 and shine on the low-temperature smoke, thereby increasing the heating speed. In addition, tempered glass or quartz glass is durable, thereby increasing the service life of the heating element assembly 1.

[0032] In one embodiment, the heating element assembly 1 further includes a sealing ring 3 , and the sealing ring 3 covers the top of the inner wall 11 and the outer wall 12 , so that the hollow cavity 14 forms a closed cavity.

[0033] In this embodiment, since the outer wall 12 is larger in diameter than the inner wall 11, the inner wall 11 is sleeved in the outer wall 12, and the top of the outer wall 12 and the top of the inner wall 11 are covered by the sealing ring 3, so that the hollow cavity 14 forms a closed cavity, which is formed by the inner annular surface of the outer wall 12, the outer annular surface of the inner wall 11, the sealing ring 3 and the bottom plate 13. The heating element 2 is arranged in the sealed hollow cavity 14, which can avoid heat loss, so that the heat in the hollow cavity 14 can be better radiated to the low-temperature smoke in the heating cavity 15. In a specific embodiment, the bottom plate 13 and the sealing ring 3 of the hollow cavity 14 are both provided with reflective materials, and only the inner wall 11 is not provided with reflective materials, so that the light in the hollow cavity 14 is reflected to the inner wall 11 by the reflective material, and then passes through the inner wall 11 to irradiate the low-temperature smoke in the heating cavity 15.

[0034] In one embodiment, the hollow cavity 14 is a vacuum cavity.

[0035] In this embodiment, the hollow cavity 14 is a vacuum cavity without any air inside, so as to reduce the loss caused by the heat and light generated by the heating element 2 being radiated into the heating cavity 15 .

[0036] In one embodiment, a clearance hole is provided on the sealing ring 3, and the clearance hole is used to penetrate the heating element 2 so that the heating element 2 is electrically connected to an external power source.

[0037] In this embodiment, a clearance hole is provided on the sealing ring 3, so that the heating element 2 passes through the clearance hole and is arranged in the hollow cavity 14. At the same time, the inner diameter of the clearance hole matches the outer diameter of the heating element 2, so that the hollow cavity 14 remains closed. In addition, the portion of the heating element 2 that passes through the clearance hole is electrically connected to an external power supply, so that the heating element 2 works normally.

[0038] In one embodiment, an elastic member is provided on the bottom plate 13 in the heating chamber 15, and the elastic force direction of the elastic member is consistent with the axial direction of the heating chamber 15; a first magnetic member is fixedly provided on the elastic member, and the second end of the heating member 2 is fixed on the second magnetic member, and the second magnetic member is provided in contact with the outer annular surface of the inner wall 11.

[0039] In this embodiment, the elastic member is a spring, one end of which is fixed to the bottom plate 13 in the heating chamber 15, and the other end is fixed with a first magnetic member, and the second magnetic member is attached to the outer annular surface of the inner wall 11. There is an interaction force between the first magnetic member and the second magnetic member, and the preferred scheme is magnetic attraction. In other schemes, it can also be a magnetic repulsion force. In this scheme, it is explained with magnetic attraction. The first magnetic member is a magnet, and the second magnetic member can be made of magnetic materials such as iron, cobalt, and nickel, and may not be a magnet. When the low-temperature cigarette is inserted into the heating chamber 15, the butt of the low-temperature cigarette resists the first magnetic member, and the first magnetic member moves toward the bottom plate 13, and correspondingly drives the second magnetic member to move toward the bottom plate 13. Thereby, the direct radiation range of the heating element 2 can be equal to or approximately equal to the length of the low-temperature cigarette. In a specific embodiment, a slide groove is further provided on the outer ring surface of the inner wall 11, and the length direction of the slide groove is consistent with the movement direction of the second magnetic member. The slide groove accommodates the second magnetic member, so that the second magnetic member can slide more easily in the slide groove under the drive of the first magnetic member, thereby better changing the radiation range of the heating element 2. By providing the elastic member, the first magnetic member, and the second magnetic member, low-temperature cigarettes of different lengths can be adapted, so that when low-temperature cigarettes of different lengths are inserted into the heating chamber 15 for heating, the heating element 2 can heat the low-temperature cigarettes efficiently.

[0040] To sum up, the heating element assembly 1 of the present application generates infrared light when the heating element 2 is energized, and the infrared light of the heating element penetrates the inner wall 11 made of the transparent material of the carrier 1 and radiates directly to the low-temperature smoke, so that the low-temperature smoke is baked by the inner wall 11, the baking area is larger, and the heating effect is faster.

[0041] In addition, the present application also proposes a low-temperature smoking device, comprising any of the heating element components 1 described above.

[0042] In this embodiment, the low-temperature smoking device includes a shell, a heating element assembly 1, a heat insulating member, a battery, and a PCBA board.
