Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a heating device and a smoke generator. Background Technology

[0002] In existing electronic cigarette heating devices, resistance heating technology is widely used, typically employing a structure design where a metal circuit is printed on the surface of a metal tube to form the heating wire. These devices generate heat through the Joule effect and rely on temperature control (TC) technology to regulate the heating temperature for precise control. However, due to the dense arrangement and small spacing of the heating wires, adjacent heating units can experience heat conduction through the metal tube material during heating, causing the heating wires in non-target areas to passively heat up, thus interfering with the overall stability of temperature control.

[0003] This thermal conduction effect not only causes local temperatures to exceed the preset range, but also affects the uniformity of nicotine and additive release in the aerosol, increasing the risk of harmful substance formation. Although existing technologies attempt to optimize the heating process by improving circuit control strategies, such as dynamically adjusting the operating voltage and current, the structural thermal interference problem has not been effectively solved, limiting the safety of e-cigarette products and the improvement of user experience. Utility Model Content

[0004] To address the shortcomings of the prior art, this invention provides a heating device and a smoke generator that avoids the heating wire in non-target heating areas from being passively heated due to heat conduction. It also provides better control over the local heating temperature of the smoke generator at the structural level, thereby ensuring the stability of the overall temperature control.

[0005] The technical effects to be achieved by this utility model are realized through the following aspects:

[0006] In a first aspect, this utility model provides a heating device, comprising:

[0007] A metal tube, the surface of which has multiple heating zones;

[0008] Multiple heating mechanisms, each of which is disposed in one of the heating regions, each heating mechanism including a circuitously distributed heating wire disposed on the outer surface of the metal tube;

[0009] A heat insulation mechanism is disposed on the metal tube and located between two adjacent heating zones to insulate the heating mechanisms of the two adjacent heating zones; and

[0010] A power supply mechanism is connected to the heating mechanism to enable the heating mechanism to generate electricity.

[0011] In some implementations, the heat insulation mechanism includes heat insulation grooves formed on the metal tube.

[0012] In this implementation, the heat insulation groove is located between two adjacent heating zones. When the heating wire in the target heating zone starts to heat up, the heat insulation groove on the metal tube reduces the amount of heat conducted through the metal tube to the heating wire in the non-target heating zone, thereby better controlling the local heating temperature of the smoke generator.

[0013] In some implementations, there are multiple heat insulation grooves, which are distributed at intervals along the metal tube and located between two adjacent heating zones.

[0014] In this implementation, multiple heat insulation grooves are located between two adjacent heating zones. While isolating heat conduction, they also ensure the strength of the metal tube body, avoiding the problem that the strength of the metal tube body would be reduced due to the opening of heat insulation grooves, which would affect the production quality of the smoke generator.

[0015] In some implementations, the gap of the heat insulation groove is any value between 0.1 and 3.0 mm.

[0016] In some implementations, the diameter of the metal tube is any value between 3 and 20 mm, the height of the metal tube is any value between 8 and 50 mm, the heating wire is wound in a roundabout manner to form a heating surface, the length of the heating surface is any value between 5 and 100 mm, and the width of the heating surface is any value between 1 and 10 mm.

[0017] In some implementations, the thickness of the metal tube is any value between 0.1 and 1 mm.

[0018] In some implementations, the power feeding mechanism includes an electrode sheet and a power feeding line, wherein the electrode sheet is connected to the end of the heating wire through the power feeding line, and the electrode sheet is provided with a solder pad.

[0019] In this implementation, both the electrode sheet and the power supply line are mounted on the metal tube. The electrode sheet is connected to the end of the heating wire through the power supply line. The electrode sheet is provided with a solder pad. The first end of the wire is connected to the electrode sheet through the solder pad, and the second end of the wire is electrically connected to the power module, thereby conducting electrical energy to the electrode sheet, which in turn causes the heating wire to heat up, ensuring the reliability of the heating device.

[0020] In some implementations, the surface of the metal tube also has a power feeding region, the electrode plates are distributed in the power feeding region, and the heat insulation mechanism is located between the power feeding region and the heating region.

[0021] In this implementation, when the heating wire in the heating area heats up, the heat insulation mechanism is located between the power supply area and the heating area, preventing the heat generated by the heating wire from being conducted to the power supply area through the metal tube. This avoids the problem of the electrode sheet being damaged by heat conduction and further extends the service life of the smoke generator.

[0022] In some implementations, the heating area is provided with multiple heating mechanisms.

[0023] Secondly, this utility model provides a smoke generator, including the heating device described above.

[0024] In summary, this utility model has at least the following advantages:

[0025] The heating device provided by this utility model has each heating mechanism set in one of the heating areas on the metal tube body. The heat insulation mechanism is set on the metal tube body and located between two adjacent heating areas. The power supply mechanism is connected to the heating mechanism to enable the heating mechanism to generate electricity. When the heating wire in the target heating area heats up, the heat insulation mechanism generates heat insulation, preventing the heating wire in the non-target heating area from being passively heated due to heat conduction. This provides better control of the local heating temperature of the smoke generator at the structural level, thereby ensuring the stability of the overall temperature control.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] Example 1:

[0038] Please see the appendix Figure 1 The heating device of this utility model includes a metal tube 100, multiple heating mechanisms 200, a heat insulation mechanism 300, and a power supply mechanism 400.

[0039] Please see below. Figure 1 , Figure 1 The diagram illustrates the structural relationship between the metal tube 100, heating mechanism 200, heat insulation mechanism 300, and power supply mechanism 400 in this embodiment of the present invention. Specifically, the surface of the metal tube 100 has multiple heating areas 101; each heating mechanism 200 is disposed in one of the heating areas 101, and the heating mechanism 200 includes a circuitously distributed heating wire 210, which is arranged on the outer surface of the metal tube 100; the heat insulation mechanism 300 is disposed on the metal tube 100 and located between two adjacent heating areas 101 to insulate the heating mechanisms 200 in the two adjacent heating areas 101; the power supply mechanism 400 is connected to the heating mechanism 200 to enable the heating mechanism 200 to generate electricity.

[0040] In this embodiment, each heating mechanism 200 is disposed in one of the heating regions 101 on the metal tube 100. The heating mechanism 200 includes a heating wire 210 that is wound around and distributed on the outer surface of the metal tube 100. The metal tube 100 is provided with a heat insulation mechanism 300, which is located between two adjacent heating regions 101, thereby isolating the heat generated by the heating mechanisms 200 in the two heating regions 101. A power supply mechanism 400 is connected to the heating mechanism 200 to enable the heating mechanism 200 to generate heat through power supply, thereby ensuring the reliability of the heating device.

[0041] Specifically, since the heat insulation mechanism 300 is installed on the metal tube 100 and located between two adjacent heating zones 101, the heat insulation mechanism 300 can provide heat insulation when the heating wire 210 in one of the heating zones 101 heats up. At the same time, it also avoids heat conduction during heating, which could lead to uneven heat distribution and unstable temperature in the metal tube 100. By installing the heat insulation mechanism 300, heat conduction is reduced, resulting in concentrated heat distribution and stable temperature.

[0042] In this embodiment, there are two heating zones: a first heating zone 1011 and a second heating zone 1012. The heating mechanisms 200 in the two heating zones are independently controlled. In some operating conditions, when the first heating zone 1011 is the target heating zone and the second heating zone 1012 is a non-target heating zone, when the heating wire 210 in the first heating zone 1011 generates heat, the heat insulation mechanism 300 provides heat insulation, thereby preventing the heat generated by the heating wire 210 in the first heating zone 1011 from being conducted to the heating wire 210 in the second heating zone 1012 through the metal tube 100. This avoids the problem of the heating wire 210 in the second heating zone 1012 being passively heated, and also avoids the problem of uneven heat distribution in the metal tube 100.

[0043] It should be noted that the heating wire 210 is formed by printing a metal circuit on the surface of the metal tube 100, thereby ensuring the compactness and reliability of the overall structure of the heating device.

[0044] In the aforementioned heating device, each heating mechanism 200 is disposed in one of the heating areas 101 on the metal tube 100. The heat insulation mechanism 300 is disposed on the metal tube 100 and located between two adjacent heating areas 101. The power supply mechanism 400 is connected to the heating mechanism 200 to enable the heating mechanism 200 to generate heat through power supply. When the heating wire 210 in the target heating area heats up, the heat insulation mechanism 300 generates heat insulation, preventing the heating wire 210 in the non-target heating area from being passively heated due to heat conduction. This provides better control over the local heating temperature of the smoke generator at the structural level, thereby ensuring the stability of the overall temperature control.

[0045] In some preferred embodiments, please continue to refer to Figure 1 , Figure 1The diagram illustrates the structural relationship between the metal tube 100 and the heat insulation groove 301 in this embodiment of the invention. Specifically, the heat insulation mechanism 300 includes a heat insulation groove 301 formed on the metal tube 100. The heat insulation groove 301 is located between two adjacent heating zones 101. When the heating wire 210 in the target heating zone starts to heat up, the heat insulation groove 301 on the metal tube 100 reduces the amount of heat conducted through the metal tube 100 to the heating wire 210 in the non-target heating zone, thereby better controlling the local heating temperature of the smoke generator.

[0046] In some preferred embodiments, there are multiple heat insulation grooves 301, which are spaced apart along the metal tube 100 and located between two adjacent heating zones 101. The multiple heat insulation grooves 301 located between two adjacent heating zones 101 not only isolate heat conduction but also ensure the strength of the metal tube 100, avoiding the problem that the strength of the metal tube 100 would decrease due to the presence of heat insulation grooves 301, thereby affecting the production quality of the smoke generator.

[0047] In some preferred embodiments, the gap of the heat insulation groove 301 is any value between 0.1 and 3.0 mm. This ensures that the metal tube 100 maintains its strength while providing good heat insulation. Preferably, the gap of the heat insulation groove 301 is 0.13 mm.

[0048] In some preferred embodiments, the diameter of the metal tube 100 is any value between 3 and 20 mm, the height of the metal tube 100 is any value between 8 and 50 mm, and the heating wire 210 forms a heating surface by meandering, with the length of the heating surface being any value between 5 and 100 mm and the width of the heating surface being any value between 1 and 10 mm. The heating wire 210, by meandering, forms a heating surface on the outer surface of the metal tube 100, thereby ensuring the reliability of the heating device, making the heating temperature of the heating area 101 more uniform, and also making the overall structure more compact.

[0049] In some more preferred embodiments, the thickness of the metal tube 100 is any value between 0.1 and 1 mm. This ensures the strength of the metal tube 100 while making it easier to carry, thereby improving portability and user experience.

[0050] Example 2:

[0051] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the heating device of this utility model. Please refer to the appendix. Figure 2 ~Appendix Figure 3 .

[0052] Please see below. Figure 2 , Figure 2 The diagram illustrates the structural relationship between the electrode sheet 410 and the power supply line 420 in this embodiment of the present invention. Specifically, the power supply mechanism 400 includes the electrode sheet 410 and the power supply line 420. The electrode sheet 410 is connected to the end of the heating wire 210 through the power supply line 420, and the electrode sheet 410 is provided with solder pads.

[0053] In this embodiment, the electrode plate 410 and the power supply line 420 are both disposed on the metal tube 100, and the electrode plate 410 is connected to the end of the heating wire 210 through the power supply line 420. The electrode plate 410 is provided with a solder pad, and the first end of the wire 500 is connected to the electrode plate 410 through the solder pad. The second end of the wire 500 is electrically connected to the power module, thereby conducting electrical energy to the electrode plate 410, which in turn causes the heating wire 210 to heat up, ensuring the reliability of the heating device.

[0054] In some preferred embodiments, please refer to Figure 3 , Figure 3 The diagram illustrates the structural relationship between the power supply region 102 and the heating region 101 in this embodiment of the invention. Specifically, the surface of the metal tube 100 also has a power supply region 102, electrode plates 410 are distributed in the power supply region 102, and the heat insulation mechanism 300 is located between the power supply region 102 and the heating region 101. When the heating wire 210 in the heating region 101 heats up, because the heat insulation mechanism 300 is located between the power supply region 102 and the heating region 101, the heat generated by the heating wire 210 is prevented from being conducted through the metal tube 100 to the power supply region 102, thereby avoiding the problem of damage to the electrode plates 410 due to heat conduction, and further extending the service life of the smoke generator.

[0055] In some preferred embodiments, the heating zone 101 is provided with multiple heating mechanisms 200. Users can adjust the heating temperature of each heating mechanism 200 in the heating zone 101 according to their needs, so that the heating wire 210 generates corresponding heat, thereby improving the user experience.

[0058] A smoke generator, comprising the heating device described above.

[0059] In this embodiment, the smoke generator achieves atomization through a heating device, ensuring the reliability of the smoke generator. Furthermore, the smoke generator also includes a temperature control chip and a power module. The temperature control chip is electrically connected to the heating device and is used to control the heating temperature of the heating device, that is, to control the power supply and power of the heating device. The power module can be a portable power source such as a DC current source or a rechargeable battery, and is used to supply power to the heating device.

[0060] In this smoke generator, each heating mechanism 200 is disposed in one of the heating areas 101 on the metal tube 100. A heat insulation mechanism 300 is disposed on the metal tube 100 and located between two adjacent heating areas 101. A power supply mechanism 400 is connected to the heating mechanism 200 to enable the heating mechanism 200 to generate electricity. When the heating wire 210 in the target heating area heats up, the heat insulation mechanism 300 provides heat insulation, preventing the heating wire 210 in the non-target heating area from being passively heated due to heat conduction. This provides better control of the local heating temperature of the smoke generator at the structural level, thereby ensuring the stability of the overall temperature control.
