Description

Technical Field

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

[0002] Electronic cigarette devices include heated tobacco products used to heat and bake a cigarette to produce aerosol or smoke for the user to inhale. These devices typically include 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 usually includes a mouthpiece and a heatable portion, which is generally made of an aerosol-generating matrix or smoke-producing tobacco material.

[0003] The magnetic induction heating components of existing electronic cigarette devices on the market include electromagnetic induction coils and induction materials for heating. Induction material heating generally includes external induction or internal induction heating. External induction is generally made into a tubular body to heat the cigarette externally.

[0004] Existing metal induction tubes have a large wall area, requiring a large amount of power from the electromagnetic coil to raise their heating temperature during electromagnetic induction heating. As a result, existing electronic cigarette devices require a large amount of power to preheat, and the entire inner wall of the induction tube heats up slowly, making it difficult for users to inhale smoke when they first start smoking, resulting in a poor user experience. Utility Model Content

[0005] This invention provides a magnetic induction heating component for electronic cigarette devices to overcome the above-mentioned technical deficiencies.

[0006] The technical solution of this utility model is implemented as follows: A magnetic induction heating component for an electronic cigarette device includes a ceramic tube, an electromagnetic coil sleeved on the outer wall of the ceramic tube, and at least two induction plates disposed on the inner wall of the ceramic tube. The cavity of the ceramic tube can be inserted into and accommodate a cigarette so that the induction plates are in close contact with the outer wall of the cigarette. The two ends of the electromagnetic coil are respectively connected to electrode leads electrically connected to a power source. When the electromagnetic coil is energized, it generates an alternating magnetic field, which causes eddy currents to be generated inside the induction plates and further generates heat. The heat from the induction plates is conducted to the outer wall of the cigarette and bakes it to produce smoke that can be inhaled into the mouth.

[0007] Preferably, the sensing element is uniformly arranged circumferentially along the inner wall of the ceramic tube.

[0008] Preferably, the inner wall of the ceramic tube is provided with a groove, and the sensing element is embedded in the groove.

[0009] Preferably, the induction sheet is made of ferrous material.

[0010] Preferably, the sensing sheet is a long, arc-shaped sheet conductor that is closely attached to the inner wall of the ceramic tube.

[0011] Preferably, the sensing sheet has several through holes.

[0012] Preferably, the ceramic tube is made of a thermally conductive, dense ceramic material.

[0013] Preferably, the inner wall of the ceramic tube and the inner wall of the sensing element are further fitted with a protective layer.

[0014] Preferably, the protective layer is made of glazed ceramic material.

[0015] Preferably, the ceramic tube, the induction plate, and the protective layer are integrally formed and sintered.

[0016] The beneficial effects of the magnetic induction heating component of this electronic cigarette device are as follows: The magnetic induction heating component of this electronic cigarette device consists of a ceramic tube, an electromagnetic coil sleeved on the outer wall of the ceramic tube, and at least two induction plates disposed on the inner wall of the ceramic tube. The ceramic tube serves to accommodate the cigarette and fix the induction plates, while also providing insulation. Because the area of ​​the induction plates is much smaller than that of the induction tube, the heating temperature can be quickly increased without consuming a large amount of power from the electromagnetic coil during electromagnetic induction heating. The rapidly heated induction plates can quickly conduct heat to the outer wall of the cigarette, making it easier for the user to inhale smoke when starting to smoke, greatly improving the user experience.

[0022] 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.

[0023] Example 1

[0024] like Figures 1-3 As shown, in this embodiment, the magnetic induction heating component of the electronic cigarette device includes a ceramic tube 1, an electromagnetic coil 2 sleeved on the outer wall of the ceramic tube, and two induction plates 3 disposed on the inner wall of the ceramic tube. The cavity 10 of the ceramic tube can be inserted into and accommodate a cigarette 5 so that the induction plates 3 are in close contact with the outer wall of the cigarette 5. The two ends of the electromagnetic coil 2 are respectively connected to electrode leads 21 and 22 that are electrically connected to the power supply. After the electromagnetic coil 2 is energized, it generates an alternating magnetic field, which causes eddy currents to be generated inside the induction plates 3 and further generates heat. The heat of the induction plates 3 is conducted to the outer wall of the cigarette 5 and bakes it to produce smoke that can be inhaled into the mouth.

[0025] The induction plate 3 is primarily a conductor, and in this embodiment, it is designed as an axially elongated arc-shaped sheet, evenly distributed along the circumference of the inner wall of the ceramic tube 1. The evenly distributed induction plates ensure that the outer wall of the cigarette receives heat uniformly for baking, resulting in even heating of the cigarette and preventing uneven baking that could lead to localized overheating or underheating.

[0026] The inner wall of the ceramic tube 1 has a groove 11, and the induction plate 3 is embedded in the groove 11. This helps to fix the induction plate 3, preventing it from deforming and loosening during long-term high-temperature operation. It also ensures that the inner wall of the induction plate 3 and the inner wall of the ceramic tube 1 are on the same inner diameter, allowing the outer wall of the cigarette 5 to fit seamlessly with the inner wall of the induction plate 3 and the inner wall of the ceramic tube 1, which facilitates heat conduction. The ceramic tube 1 is insulating to ensure insulation between the electromagnetic coil 2 and the induction plate 3.

[0027] The induction plate 3 is made of iron material, that is, the induction plate 3 is an induction iron plate, which can better generate eddy currents in alternating electromagnetic fields.

[0028] The sensing element 3 is a long, arc-shaped sheet conductor that is closely attached to the inner wall of the ceramic tube 1, so that the sensing element 3 can better adhere to the outer wall of the cigarette 5.

[0029] The ceramic tube 1 is made of thermally conductive dense ceramic material. The thermally conductive dense ceramic material helps to absorb the heat of the induction plate 3 and further conduct it to the outer wall of the cigarette 5, so that the outer wall of the cigarette 5 is heated more evenly.

[0030] Example 2

[0031] like Figure 4As shown, the magnetic induction heating component of the electronic cigarette device in this embodiment has the same structure as that in Embodiment 1 above, but its sensing plate 3 is provided with several through holes 30. The several through holes 30 can reduce the surface area of ​​the sensing plate 3, so that the sensing plate 3 can generate heat more quickly and in a more concentrated manner. At the same time, during manufacturing, the several through holes 30 can be filled with the ceramic material of the ceramic tube 1, so that the sensing plate 3 and the ceramic tube 1 fit more tightly, are better fixed, and are less prone to deformation.

[0032] Example 3

[0033] like Figure 5 As shown, the magnetic induction heating component of the electronic cigarette device in this embodiment has the same structure as that in Embodiment 1, but the induction plate 3 is increased to three pieces, which can improve the heating efficiency. In addition, a protective layer 4 is also provided on the inner wall of the ceramic tube 1 and the inner wall of the induction plate 3. The protective layer is made of glazed ceramic material, and the ceramic tube 1, the induction plate 3 and the protective layer 4 are integrally formed and sintered. The protective layer 4 can isolate the induction plate 3 from the outer wall of the cigarette, preventing the induction plate 3 from coming into contact with the smoke, tar or soot generated by the heating of the cigarette during long-term use, protecting the induction plate 3 and preventing it from rusting and scaling, which would reduce the efficiency of electromagnetic induction.

[0034] The magnetic induction heating component of this electronic cigarette device consists of a ceramic tube, an electromagnetic coil sleeved on the outer wall of the ceramic tube, and at least two induction plates disposed on the inner wall of the ceramic tube. The ceramic tube serves to accommodate the cigarette and fix the induction plates, while also providing insulation. Since the area of ​​the induction plates is much smaller than that of the induction tube, the heating temperature can be quickly increased without consuming a large amount of power from the electromagnetic coil during electromagnetic induction heating. The rapidly heated induction plates can quickly conduct heat to the outer wall of the cigarette, making it easier for the user to inhale smoke when starting to smoke, greatly improving the user experience.

[0035] 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.
