Description

Technical Field

[0001] This utility model relates to the technical field of heated non-combustible smoking devices, and more specifically, to a heating element for an electronic smoking device. Background Technology

[0002] An electronic cigarette device is a heated tobacco product used to heat a cigarette to produce an aerosol or smoke for the user to inhale. An electronic cigarette device generally includes a casing, a power supply unit, and a heating element. The power supply unit contains a battery that powers the heating element, which, when powered, heats the aerosol-generating matrix or the tobacco portion of the cigarette to produce aerosol or smoke. The cigarette typically includes a mouthpiece and a heatable portion, which is generally made of an aerosol-generating matrix or smoke-producing tobacco material.

[0003] The heating components of existing electronic cigarette devices on the market mainly include resistance wire heating and electromagnetic induction coil heating. Both methods require heating elements such as heating tubes or heat-conducting tubes to heat the outside of the cigarette, or heating needles, heat-conducting needles, or heating plates / plates to heat the inside of the cigarette. When using external heating, the heat-conducting tube is mainly made of metal to ensure good heat conduction. Generally, when a user turns on an electronic cigarette device, the heating element must first be turned on to preheat the cigarette before inhaling vapor. Existing metal heat-conducting tubes typically heat the entire outer wall of the tube through a heating resistor. Because the tube wall area is relatively large, the heating resistor needs to consume a lot of power to raise the heating temperature. Therefore, existing electronic cigarette devices require a large power load during preheating, and the entire inner wall of the heat-conducting tube heats up slowly. This makes it difficult for users to inhale vapor at the beginning of smoking, and the inhaled air is still relatively hot, which can easily burn the mouth, resulting in a poor user experience. Utility Model Content

[0004] This invention provides a heating element for an electronic cigarette device to overcome the above-mentioned technical deficiencies.

[0005] The technical solution of this utility model is implemented as follows: A heating component for an electronic cigarette device includes a heat-conducting pipe and a heating coil. The inner wall of the heat-conducting pipe can be tightly inserted into a cigarette. At least two narrow, elongated heat-insulating through holes are longitudinally provided on the wall of the heat-conducting pipe, so that the wall of the heat-conducting pipe can be divided into at least two heat-conducting regions. Resistive heating coils are respectively tightly attached to the outer wall of the heat-conducting pipe in different heat-conducting regions. The two ends of each heating coil are respectively connected to a positive lead and a negative lead electrically connected to a power source. Each heating coil can be energized individually or simultaneously. After being energized, the heating coil generates heat and heats the heat-conducting pipe. The heat-conducting pipe conducts heat to the outer wall of the cigarette and bakes it to produce smoke that can be inhaled into the mouth.

[0006] Preferably, the heat insulation holes are uniformly arranged along the circumference of the heat-conducting pipe wall, and each heat-conducting region has the same outer surface area.

[0007] Preferably, each of the heating coils has the same shape and size.

[0008] Preferably, the heat pipe is made of metal or ceramic material.

[0009] Preferably, the heat pipe is a metal heat pipe, and the outer surface of the metal heat pipe is oxidized to form a metal oxide layer, which has the properties of being non-conductive but easily conductive.

[0010] Preferably, the heat pipe is an aluminum heat pipe, and the outer wall surface of the aluminum heat pipe is oxidized to form an aluminum oxide layer.

[0011] Preferably, one end of the negative lead of the heating coil is configured as a ring-shaped common terminal.

[0012] Preferably, the heating coil is formed by etching a metal sheet.

[0013] The beneficial effects of the heating component of this electronic cigarette device are as follows: The heating component of this electronic cigarette device includes a heat-conducting pipe and a heating coil. At least two narrow, elongated heat-insulating holes are longitudinally arranged on the wall of the heat-conducting pipe, dividing the pipe wall into at least two heat-conducting regions. Heating coils can be independently and tightly attached to the outer wall of the heat-conducting pipe where each heat-conducting region is located. When any one heating coil heats up, the heat in that region is difficult to conduct to the other region due to the isolation provided by the heat-insulating holes. Thus, during the preheating of the electronic cigarette device, all power can be concentrated on one heating coil, concentrating heat in one heat-conducting region. This allows the region to heat up quickly and locally heat the cigarette, enabling faster smoke extraction. Simultaneously, another part of the cigarette is not heated. When the user inhales, the airflow through this part is at a lower temperature and mixes with the airflow from the heated part, lowering the temperature of the inhaled smoke and preventing burns to the mouth.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0017] Example

[0018] like Figure 1 , Figure 2 As shown, the heating component of the electronic cigarette device of this utility model includes a heat-conducting pipe 1 and a heating coil 2. The inner wall of the heat-conducting pipe 1 can be tightly inserted into and accommodate a cigarette 4. Two narrow, elongated heat-insulating holes 10 are longitudinally provided on the wall of the heat-conducting pipe 1, which serve to block heat conduction around the pipe wall. A resistive heating coil 2 is tightly attached to the outer wall of the heat-conducting pipe 1 between the two heat-insulating holes 10, for a total of two heating coils 2. The two ends of the two heating coils 2 are respectively connected to a positive lead 31 and a negative lead 32 connected to a power source. The two heating coils 2 can be energized separately or simultaneously. When the heating coils 2 are energized, they generate heat and heat the heat-conducting pipe 10. The heat-conducting pipe 10 conducts heat to the outer wall of the cigarette 3 and bakes it, producing smoke that can be inhaled into the mouth.

[0019] In this embodiment, two narrow, elongated heat-insulating through holes 10 are longitudinally provided on the wall of the heat-conducting pipe 1, so that the wall of the heat-conducting pipe 1 can be divided into two heat-conducting regions 11 and 12. Heating coils 2 can be independently and tightly attached to the outer wall of the heat-conducting pipe where the two heat-conducting regions 11 and 12 are located. When any one of the heating coils 2 is energized and works to generate heat, the heat in the heat-conducting region where the heating coil 2 is located is isolated by the heat-insulating through holes 10, and the heat is difficult to conduct to the heat-conducting region where the other heating coil is not working. That is, when one of the heating coils 2 is energized and works to generate heat, its heat is only conducted in the heat-conducting region where the heating coil is located. In this way, when the electronic cigarette device is turned on and preheating, all power can be concentrated on one heating coil first, so that the heat is concentrated in a heat-conducting area. This allows the heat-conducting area to heat up quickly and locally heat the cigarette stick 4, so that the cigarette stick 4 can be inhaled more quickly. At the same time, another part inside the cigarette stick 4 is not heated. When the user inhales, the airflow through this part is at a lower temperature. It can mix with the airflow of the heated part, so that the temperature of the inhaled smoke is lowered, and the smoke avoids burning the mouth.

[0020] In this embodiment, two heat-insulating through holes 10 are uniformly arranged circumferentially along the wall of the heat-conducting pipe 1, that is, the two heat-insulating through holes 10 are symmetrically arranged along the wall of the heat-conducting pipe 1, so that the two heat-conducting regions 11 and 12 have the same outer surface area, and the two heating coils 2 have the same shape and size. This allows each heat-conducting region to have the same power of heat, so that the circumferential heating effect is the same and the heating is uniform.

[0021] In other embodiments, the elongated heat-insulating through holes 10 provided on the heat pipe 1 can be evenly arranged into 3, 4 or more, so as to divide 3, 4 or more heat-conducting areas. At the same time, heating coils are provided on each heat-conducting area so that the heat can be more concentrated to heat the smaller heat-conducting area.

[0022] In other embodiments, the heat insulation through holes 10 may also be non-uniformly arranged along the circumference of the heat-conducting pipe 1, so that each heat-conducting area has a different outer surface area. In addition, different heating coils 2 may also have different shapes and sizes, so that the circumference of the pipe wall can be asymmetrically and unevenly heated, so as to adjust the heat output of different power at different smoking stages and make them have different smoke volumes.

[0023] In this invention, the heat pipe 1 is made of metal or ceramic material.

[0024] In this invention, the heat pipe 1 is a metal heat pipe. The outer surface of the metal heat pipe 1 is oxidized to form a metal oxide layer. The metal oxide layer can have the properties of being non-conductive but easily conductive.

[0025] In this embodiment, the heat pipe 1 is an aluminum heat pipe. The outer wall surface of the aluminum heat pipe is oxidized to form an aluminum oxide layer. The aluminum oxide layer has good insulation properties and good thermal conductivity.

[0026] In this embodiment, one end of the negative lead of the two heating coils 2 is set as a ring-shaped common end 21, which is a ring-shaped metal ring, so as to be fixed to the outer wall of the heat pipe 1.

[0027] In this embodiment, the heating coil 2 is formed by etching a metal sheet. Etching the metal sheet facilitates processing, improves production efficiency, and is not easily deformed.

[0028] The above description is merely a preferred embodiment of the present utility model, and the specific embodiments described above are not intended to limit the present utility model. Various modifications and variations can be made within the scope of the technical concept of the present utility model. All refinements, modifications, or equivalent substitutions made by those skilled in the art based on the above description are within the scope of protection of the present utility model.
