Description

Technical Field

[0001] This invention belongs to the field of tobacco technology, specifically relating to a spherical enclosed infrared heating smoking device. Background Technology

[0002] Traditional tobacco combustion produces harmful substances such as tar, carbon monoxide, and polycyclic aromatic hydrocarbons, which can lead to various diseases when ingested. Heated tobacco products, on the other hand, only heat tobacco materials or tobacco extracts without combustion, significantly reducing the release of harmful substances in the smoke and minimizing harm to the environment and surrounding populations.

[0003] Currently, heated cigarettes mainly use resistance heating and electromagnetic heating. The essence of these two methods is that the heat source must be in direct contact with the tobacco material, which leads to uneven heating of the tobacco core: the section of the tobacco core near the heat source is overheated and easily carbonized, resulting in a burnt aroma that affects the taste; simultaneously, the section of the tobacco core further away from the heat source is underheated, leading to insufficient release of aroma and active ingredients. Therefore, the industry has developed infrared heating methods. Infrared heating devices introduce infrared light as a heat transfer medium. Because infrared light has strong penetrating power, it can directly reach the interior of the tobacco core, greatly increasing the heated area of ​​the tobacco material and making it more evenly and fully heated.

[0004] An infrared generator produces infrared radiation of a specific wavelength. When this infrared radiation matches the absorption wavelength of the cigarette wick, it heats the wick. However, because the infrared radiation generated by the generator disperses in space, not all of it can be precisely positioned within the heating cavity. Some infrared radiation escapes the heating cavity, resulting in low infrared energy utilization. Furthermore, the infrared generator produces infrared radiation over a relatively wide wavelength range, while the inherent absorption wavelength of the cigarette wick is relatively narrow. When the wavelength of the infrared radiation generated by the generator is greater than or less than the inherent absorption wavelength of the cigarette wick, this portion of infrared radiation cannot be fully utilized, further contributing to low infrared energy utilization. Therefore, current infrared-heated cigarette appliances suffer from the problem of low infrared energy utilization.

[0005] The present invention is proposed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a spherical enclosed infrared heating smoke appliance, which has an infrared correction coating and an infrared reflection coating, greatly improving the energy utilization rate of infrared rays.

[0007] The technical solution of the present invention is as follows:

[0008] A spherical enclosed infrared heating smoke appliance, comprising an infrared heating system 1 and an infrared reuse system 2;

[0009] The infrared heating system 1 includes: an infrared generating coating 13, a conductive coating 12, and an infrared support 11; the infrared support 11 is cylindrical, its inner wall is coated with a conductive coating 12, and then an infrared generating coating 13 is coated on the surface of the conductive coating 12.

[0010] The infrared reuse system 2 includes: an infrared correction coating support 22 and a heat insulation protective sleeve 24; the infrared correction coating support 22 is cylindrical and its inner surface is coated with an infrared correction coating 21; the inner surface of the heat insulation protective sleeve 24 is an elliptical surface and an infrared reflective coating 23 is coated on the elliptical surface.

[0011] Preferably, the infrared heating system 1 has a heating sleeve 14 inside, and the heating sleeve 14 has a heating cavity inside.

[0012] Preferably, the spherical enclosed infrared heating smoke appliance further includes a power control system 3; the power control system 3 includes a power supply 31 and a control circuit board 32; the conductive coating 12 is electrically connected to the power control system 3.

[0013] Preferably, the outer periphery of the heat insulation protective sleeve 24 is a shell 25; the power control system 3 is arranged inside the shell 25 at the lower part of the infrared heating system 1 and the infrared reuse system 2.

[0014] Preferably, the infrared correction coating 21 contains a nonlinear material that can change the wavelength of infrared light.

[0015] Preferably, the nonlinear material that can change the infrared wavelength is a frequency doubling crystal material or a fluorescent material.

[0016] The working principle of the spherical enclosed infrared heating tobacco device of the present invention is as follows: a non-combustible tobacco product is added into the heating cavity inside the heating sleeve 14. After the conductive coating 12 is energized, the infrared radiation emitted by the infrared generating coating 13 heats the non-combustible tobacco product. At the same time, the infrared radiation radiated outside the heating cavity (mainly infrared radiation with wavelengths lower or higher than the inherent absorption wavelength of the non-combustible tobacco product, which cannot be utilized by the non-combustible tobacco product) is transformed into infrared radiation within a specific wavelength range after passing through the infrared polarization coating 21. Due to the focusing effect of the elliptical surface, it is reflected by the infrared reflection coating 23 and then reflected back into the heating cavity, realizing the reuse of infrared energy.

[0017] The beneficial effects of this invention are:

[0018] 1. The spherical enclosed infrared heating tobacco device of the present invention has an infrared correction coating 21 that converts infrared wavelengths that cannot be used by heated non-combustible tobacco products into infrared wavelengths that can be used by heated non-combustible tobacco products, thereby improving the energy utilization rate of infrared rays from the perspective of the physical properties of infrared rays.

[0019] 2. The spherical enclosed infrared heating smoker of the present invention has an infrared reflective coating 23 that reflects the infrared rays that overflow from the heating cavity back into the heating cavity, thereby improving the energy utilization rate of infrared rays from the structural design of the smoker.
