Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat-not-burn electronic cigarettes, in particular to a heating component, a herbal heating tube and a heat-not-burn electronic cigarette. Background Art
[0002] In the current technology, heat-not-burn heating tubes usually adopt stainless steel tubes, outer sleeves or sintered heating wires or electromagnetic heating. However, the thermal conductivity of stainless steel is only about 26 W / (m*k), resulting in uneven heating. Uneven heating will cause hot spots to form locally on the heating tube, thus generating harmful substances and affecting the taste. Another common method is to use an aluminum alloy tube for grooved heating, but this method will weaken the structural strength and cause the heating tube to deform after long-term use. There is also a common way to combine multiple groups of metal tubes with high-temperature resistant plastic tubes (such as PEEK, Teflon, etc.). However, when the metal tube is heated, the temperature inside the high-temperature resistant plastic tube is too low (lower than 100 degrees Celsius), resulting in condensation water, thus unable to generate enough smoke or only generating a small amount of smoke. At the same time, when the previous section of the heating tube finishes working and the next section starts working, the heat of the previous section of the heating tube cannot be fully transferred to the next section of the heating tube, resulting in power waste.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Refer to Figures 1 to 4 As shown, the embodiment of the present utility model provides a heating component 10, which includes a first heating tube 100, a second heating tube 200 and a connecting tube 300; the second heating tube 200 is arranged at an interval and coaxially with the first heating tube 100; wherein, the thermal conductivity coefficients of the first heating tube 100 and the second heating tube 200 are greater than 100 W / (m·k); the connecting tube 300 is respectively connected to the first heating tube 100 and the second heating tube 200, and the thermal conductivity coefficient of the connecting tube 300 is 5 - 50 W / (m·k).
[0027] In the heating component 10 of this embodiment, by setting the first heating tube 100 (the second heating tube 200) with different thermal conductivity coefficients to cooperate with the connecting tube 300, during the heating process, while the heat is conducted through the connecting tube 300, the heat of the other heating tube can be reduced, thereby improving the problem of local overheating in the heating component 10 and improving the heating uniformity of the heating component 10. When this heating component 10 is applied to a heat-not-burn electronic cigarette, the heating uniformity and the use effect of the electronic cigarette can be effectively improved.
[0028] Specifically, the material of the first heating tube 100 is any one of aluminum alloy, copper and silver, and the material of the second heating tube 200 is any one of aluminum alloy, copper and silver.
[0029] Understandably, by using any one of aluminum alloy, copper, and silver as the material of the first heating tube 100 and the second heating tube 200, the first heating tube 100 and the second heating tube 200 can have a thermal conductivity greater than 100 W / (m*k). Due to the difference in thermal conductivity between the first heating tube 100 and the connecting tube 300, during the heating process of the first heating tube 100, the heat conducted toward the second heating tube 200 via the connecting tube 300 can be restricted. At the same time, the heat emitted by the first heating tube 100 can be shared to reduce the phenomenon of local high heat generation in the first heating tube 100, thereby improving the heating uniformity of the heating assembly 10. The same applies to the second heating tube 200 and will not be elaborated here.
[0030] In one embodiment, the first heating tube 100 and the second heating tube 200 are respectively inserted into opposite sides of the connecting tube 300, and the first heating tube 100 and the second heating tube 200 are respectively fixed to the connecting tube 300 by welding.
[0031] With this arrangement, when assembling the first heating tube 100, the second heating tube 200, and the connecting tube 300, the first heating tube 100 and the second heating tube 200 can be respectively inserted into opposite ends of the connecting tube 300 to position the installation positions of the first heating tube 100 and the second heating tube 200 in the connecting tube 300. Then, the first heating tube 100, the second heating tube 200, and the connecting tube 300 are fixed by welding, and the assembly of the heating assembly 10 can be completed, ensuring a stable connection between the first heating tube 100, the second heating tube 200, and the connecting tube 300.
[0032] Specifically, the first heating tube 100 further includes a first heating portion 110, and the first heating portion 110 is disposed around the body of the first heating tube 100; the second heating tube 200 further includes a second heating portion 210, and the second heating portion 210 is disposed around the body of the second heating tube 200.
[0033] By providing the first heating portion 110 on the first heating tube 100, the first heating portion 110 can be connected to an external circuit, and by starting it, the heating function of the first heating portion 110 can be realized to heat the herbaceous material in the first heating tube 100; similarly, by providing the second heating portion 210 on the second heating tube 200, the second heating portion 210 can be connected to an external circuit, and by starting it, the heating function of the second heating portion 210 can be realized to heat the herbaceous material in the second heating tube 200. Specifically, the herbaceous material includes but is not limited to tobacco.
[0034] Such as Figure 2As shown, in a preferred embodiment, the number of the first heating parts 110 is one or more, and the plurality of first heating parts 110 are arranged at intervals along the body of the first heating tube 100; the number of the second heating parts 210 is one or more, and the plurality of second heating parts 210 are arranged at intervals along the body of the second heating tube 200; and / or the first heating parts 110 are fixed to the first heating tube 100 by sintering, and the second heating parts 210 are fixed to the second heating tube 200 by sintering.
[0035] In this embodiment, by arranging a plurality of first heating parts 110 and second heating parts 210, the first heating parts 110 can be evenly distributed along the axial direction of the first heating tube 100, and at the same time, the plurality of second heating parts 210 can be evenly distributed along the axial direction of the second heating tube 200. Thereby, the heating range of the first heating parts 110 and the second heating parts 210 can be increased, and thus the heating uniformity of the first heating tube 100 and the second heating tube 200 can be improved.
[0036] In one embodiment, the diameters of the first heating tube 100 and the second heating tube 200 are not less than 8 mm, and the diameter of the connecting tube 300 is greater than or equal to the diameters of the first heating tube 100 and the second heating tube 200.
[0037] With such a setting, when the heating component 10 is applied to an electronic cigarette, the electronic cigarette can have a smaller diameter size, which is convenient for carrying and using.
[0038] The present utility model further provides a herbal heating tube, which comprises the heating component 10 in any one of the above embodiments.
[0039] It can be understood that in the herbal heating tube of this embodiment, the interior of the herbal heating tube is a hollow structure and is used to accommodate herbs; by arranging the heating component 10 in any one of the above embodiments, the heating component 10 cooperates with the connecting tube 300 by setting the first heating tube 100 (the second heating tube 200) with different thermal conductivities (W / (m*k)). During the heating process, while the heat is conducted through the connecting tube 300, the heat of the other heating tube can be reduced, thereby improving the problem of local overheating in the heating component 10, so as to improve the heating uniformity of the heating component 10, and further make the herbal heating tube have better heating uniformity and good use effect.
[0040] As Figure 2 shown in the embodiment, the overall length L of the heating component 10 is 42.50 mm, and the diameter D1 of the first heating tube 100 and the second heating tube 200 is 8.40 mm. Please refer to Figure 3, the inner diameter D0 of the heating component 10 is 8 mm, the outer diameter of the connecting pipe 300 is 8.84 mm, the distance L1 between the first heating part 110 near the side of the first heating pipe 100 away from the connecting pipe 300 and the end of the first heating pipe 100 is 4 mm, the distance L2 between two adjacent first heating parts 110 is 0.5 mm, the distance between two adjacent second heating parts 210 is 6 mm, the distance L4 between the second heating part 210 near the side of the second heating pipe 200 away from the connecting pipe 300 and the end of the second heating pipe 200 is 5 mm, the width A of the first heating part 110 and the second heating part 210 is 4 mm, and the length B is 25 mm.
[0041] The present utility model also provides a heat-not-burn electronic cigarette, which includes the heating component 10 in any one of the above embodiments, or the herbal heating pipe in any one of the above embodiments.
[0042] It can be understood that in the heat-not-burn electronic cigarette of this embodiment, by setting the heating component 10 in any one of the above embodiments, the heating component 10 cooperates with the connecting pipe 300 by setting the first heating pipe 100 (the second heating pipe 200) with different thermal conductivities. During the heating process, while the heat is conducted through the connecting pipe 300, the heat of the other heating pipe can be reduced, thereby improving the problem of local overheating in the heating component 10, improving the heating uniformity of the heating component 10, and further enabling the heat-not-burn electronic cigarette to have better heating uniformity and improved use effect.
[0043] The present utility model also provides a heating method for a heat-not-burn electronic cigarette, which adopts the heating component 10 in any one of the above embodiments. The heating method includes the following steps:
[0044] Step S100: Provide herbal material and place it in the heating component 10;
[0045] Step S200: Start the first heating pipe 100 to heat the herbal material. The connecting pipe 300 of the heating component 10 conducts the heat of the first heating pipe 100 to the second heating pipe 200, and the temperature of the second heating pipe 200 is lower than that of the first heating pipe 100;
[0046] Step S300: Stop the heating of the first heating pipe 100 and start the second heating pipe 200 to heat the herbal material. The step of starting the first heating pipe 100 to heat the herbal material specifically includes: the heat conducted by the first heating pipe 100 heats the connecting pipe 300 to above 100°C
[0047] In the heating method of this embodiment, by controlling the heating between the first heating pipe 100, the second heating pipe 200 and the connecting pipe 300, the connecting pipe 300 can limit the heat conduction while conducting the temperature between the first heating pipe 100 and the second heating pipe 200. When the first heating pipe 100 starts to heat, the heat is evenly released in the first heating pipe 100, and the connecting pipe 300 also absorbs part of the heat and keeps its temperature above 100°C. Before a period of time before the herbs or other herbs in the first heating pipe 100 are released completely, the second heating pipe 200 is preheated simultaneously, and then the heating of the first heating pipe 100 is stopped and the heating of the second heating pipe 200 is started. The heat of the first heating pipe 100 can also be conducted to the second heating pipe 200 through the connecting pipe 300. Such a setting can make the heating of the heating component 10 more uniform, the harmful substance precipitation lower, and the power lower, with good use effects. During the operation of the heat-not-burn electronic cigarette, the preheating time or the heating power can be adjusted according to the heater temperature to adjust and control the heating effect of the heat-not-burn electronic cigarette.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
