However, in this technology, the part of the cigarette that needs to be heated is generally heated as a whole, resulting in slow heating efficiency. When users use electronic cigarettes to smoke electronic cigarettes, they need to wait for a long time before they can smoke after putting the cigarette into the electronic cigarette, which leads to poor user experience.

Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.
[0042] Heating without burning is a technology that uses a special heating device to heat a special "cigarette bomb" or "cigarette" at a low temperature until it emits smoke, avoiding the toxic and harmful substances produced by high-temperature combustion, while being able to experience a taste and flavor close to that of cigarettes. The heating without burning technical solution uses a thin steel sheet to etch a loop, and the loop is adhered to the outer wall of a metal tube. The heat is transmitted to the metal tube through a resistance wire, and then the cigarette is heated through the inner wall of the metal tube. However, in this technical solution, the heat-generating part of the cigarette is generally heated as a whole, resulting in slow heating efficiency. When users use electronic cigarette devices to smoke electronic cigarettes, they need to wait for a long time after putting the cigarette into the electronic cigarette device before they can smoke, which results in a poor user experience.
[0043] See also Figures 2 to 7 An embodiment of the present application provides a heating module 10, including a heating component 20 and an isolating member 23, wherein the heating component 20 includes a first heating unit 21 and a second heating unit 22 arranged in sequence along a first direction, wherein a heating rate of the first heating unit 21 is higher than a heating rate of the second heating unit 22; the isolating member 23 is at least sleeved on the outer side of the heating component 20.
[0044] The embodiment of the present application divides the heating component 20 into a first heating unit 21 and a second heating unit 22, wherein the heating rate of the first heating unit 21 is higher than that of the second heating unit 22, so that when a user uses the electronic smoking device 100 for inhalation, the cigarette 1 is placed into the electronic smoking device 100, and when the heating component 20 is used for heating, the first heating unit 21 can be used to quickly heat up a part of the cigarette 1, and the heating component 20 can be insulated by the isolation member 23 to reduce the heat loss of the heating component 20, thereby quickly producing the first puff of cigarette and reducing the waiting time for the user to have the first puff of cigarette. Compared with the overall heating solution, the solution of the present application has a fast heating rate and can quickly produce the first puff of cigarette for the user.
[0045] It should be noted that the first heating unit 21 and the second heating unit 22 are arranged sequentially in the first direction. The first heating unit 21 may be arranged closely in the first direction, or may be arranged at intervals, which is not limited here. The specific implementation form of the first heating unit 21 and / or the second heating unit 22 is not limited, and may be in the form of a heating net, a printed circuit, a carbon fiber heating element, etc., which is not limited here. The heating rate of the first heating unit 21 is higher than the heating rate of the second heating unit 22. The specific implementation form is not limited, and the heating power of the first heating unit 21 may be larger, or when the heating power of the first heating unit 21 and the second heating unit 22 are the same, the heating area of the first heating unit 21 may be smaller, and so on, which is not limited here.
[0046] The heating rate refers to the length of time taken to heat the cigarette 1 from room temperature to the smoking temperature. For example, the longer the time taken to heat the cigarette 1 from room temperature to the smoking temperature, the slower the heating rate. Conversely, the shorter the time taken, the faster the heating rate.
[0047] The first heating unit 21 and the second heating unit 22 can be arranged in series or in parallel. When arranged in series, the two must be turned on or off at the same time. Therefore, in a further embodiment, the first heating unit 21 and the second heating unit 22 are arranged in parallel. Corresponding to the technical solution of this embodiment, by arranging the first heating unit 21 and the second heating unit 22 in parallel, the first heating unit 21 and the second heating unit 22 can be controlled independently of each other, and each can be independently turned on and off.
[0048] Furthermore, in one embodiment, the first heating unit 21 and the second heating unit 22 generate heat alternately. In this configuration, only one heating unit in the heating module 10 generates heat at a time, so that during the heating process, the power supply of the electronic cigarette device 100 only needs to supply power to one of the first heating unit 21 and the second heating unit 22. Correspondingly, the heating power of the first heating unit 21 and the second heating unit 22 can be made consistent with, or similar to, the heating power of the existing whole-section heating unit, so that the heating power that originally heated the entire section is now only used to heat a part, which greatly improves the smoking efficiency of the cigarette 1.
[0049] Specifically, the initial resistance of the heating unit needs to be as small as possible while ensuring safety. For example, when using commonly used 18650 series batteries, the resistance can be configured to be between 0.4Ω and 1Ω.
[0050] Furthermore, the first heating unit 21 and the second heating unit 22 may be independently arranged, so that a short circuit between the first heating unit 21 and the second heating unit 22 can be effectively avoided.
[0051] In one embodiment, the first heating unit 21 has a first pin 211 and a second pin 212, and the second heating unit 22 has a third pin 221 and a fourth pin 222; wherein the first pin 211 and the third pin 221 are arranged at intervals, and the second pin 212 and the fourth pin 222 are arranged in an integrated manner.
[0052] In this configuration, since the second pin 212 and the fourth pin 222 are integrated, the two are connected together, and the resistance value at the corresponding pin is small, so that the heat generated at the pin is small, so that the heat can be concentrated on the part that needs to be heated.
[0053] Furthermore, in order to produce smoke more quickly and generate the first puff of smoke, the heating rate of the first heating unit 21 is more than twice the heating rate of the second heating unit 22, so that when the user uses the electronic cigarette, the first heating unit 21 can be used for heating first to quickly produce the first puff of smoke. After the first puff of smoke is produced, the first heating unit 21 and the second heating unit 22 can be heated alternately to heat different parts of the cigarette 1.
[0054] It should be emphasized that the heating rate of the first heating unit 21 is more than twice that of the second heating unit 22 , and the heating rate of the first heating unit 21 may be twice, three times, four times, etc., that of the second heating unit 22 .
[0055] Specifically, in one embodiment, the heating power of the first heating unit 21 and the second heating unit 22 are consistent, and the first heating unit 21 is a resistance wire. Correspondingly, at this time, the heating rate of the first heating unit 21 is the fastest.
[0056] In addition, the first heating unit 21 and the second heating unit 22 are not limited in the heating parts of the cigarette 1. One may heat the head of the part that needs to be heated of the cigarette 1, and the other may heat the tail of the cigarette 1. Specifically, the first heating unit 21 may heat the head of the part that needs to be heated of the cigarette 1, and the second heating unit 22 may heat the tail of the cigarette 1. Alternatively, the second heating unit 22 may heat the head of the part that needs to be heated of the cigarette 1, and the first heating unit 21 may heat the tail of the cigarette 1. There is no limitation here.
[0057] Please also read Figure 1 The cigarette 1 is divided into a smoking section, a cooling section and a filter section. The smoking section includes a first smoking section 11 and a second smoking section 12 close to the filter section. In one embodiment, when the heating component 20 is used to heat the cigarette 1, the first heating unit 21 is used to heat the portion of the cigarette 1 close to the cigarette holder, and the second heating unit 22 is used to heat the portion of the cigarette 1 away from the cigarette holder. With this arrangement, the portion heated by the first heating unit 21 is the portion close to the cigarette holder. After smoking, the distance between the smoke and the cigarette holder is short, and the user can quickly inhale the smoke when inhaling. Specifically, the first heating unit 21 is used to heat the first smoking section 11, so that the first smoking section 11 can smoke quickly.
[0058] Furthermore, the specific implementation form of the heating component 20 is not limited, and it can be a heating net, a carbon fiber heating element, a printed circuit, etc. Specifically, the carbon fiber heating element is a tubular heating element made of carbon fiber as the basic heating material, which uses a reflective surface to dissipate heat, and the electric heat conversion rate is more than 95%, which saves 30% energy compared with nickel-chromium, tungsten-molybdenum and other materials as heating elements. When the isolation member 23 is a PI film, the heating component 20 can also be a printed circuit, so that the printed circuit is printed on the PI film, and the printed PI film is wrapped around the outside of the heat conductor to form the heating module.
[0059] In one embodiment, the heating component 20 includes a heating net, the first heating unit 21 includes a first heating net, and the second heating unit 22 includes a second heating net; wherein the first heating net includes a plurality of first resistance wires 213 arranged at intervals, and the second heating net includes a plurality of second resistance wires 223 arranged at intervals.
[0060] In the technical solution of this embodiment, by setting the first heating unit 21 as a first heating net, the second heating unit 22 as a second heating net, and each heating net including a plurality of resistance wires, the heating uniformity can be improved compared with the solution of a single resistance wire.
[0061] In a further embodiment, the gaps between the first resistance wires 213 are smaller than the gaps between the second resistance wires 223. With this configuration, the density of the resistance wires of the first heating unit 21 is greater, and the corresponding heating rate is also higher.
[0062] Alternatively, the cross-sectional area of the first resistance wire 213 is smaller than the cross-sectional area of the second resistance wire 223. In this configuration, the resistance value of the first resistance wire 213 is greater than the resistance value of the second resistance wire 223, thereby making the heating rate of the first heating unit 21 faster.
[0063] Furthermore, the width of the first resistance wire 213 is 0.2 to 2 mm, and the first resistance wire 213 is an austenitic stainless steel part. By setting it in this way, by limiting the width and material of the first resistance wire 213, the maximum heating temperature of the first resistance wire 213 can be limited, so that the maximum temperature of the first resistance wire 213 will not be too high, thereby avoiding scorching the cigarette 1 and affecting the quality of the smoke.
[0064] In addition, the heating module 10 also includes a heat-conducting tube 40, which has an insertion channel 41 suitable for inserting a cigarette 1; the heating component 20 is arranged on the outside of the heat-conducting tube 40; the isolation member 23 includes a heat-insulating film, which includes a first film segment 231 located between the heat-conducting tube 40 and the heating component 20 and a second film segment 232 located on the outside of the heating component 20; wherein the first film segment 231 surrounds the outside of the heat-conducting tube 40 for one week, and the second film segment 232 surrounds the outside of the heat-conducting tube 40 for at least three weeks.
[0065] In the technical solution corresponding to the present embodiment, the heating component 20 is arranged on the outside of the heat pipe 40, so that the heat emitted by the heating component 20 can be transferred to the cigarette 1 by the heat pipe 40 to heat the cigarette 1, and the heat pipe 40 can play the role of heat conduction and heat uniformity.
[0066] It is understandable that the heat pipe 40 can be a metal pipe or a plastic pipe, which is not limited here. When the heat pipe 40 is a metal pipe, by setting the first film segment 231, the first film segment 231 can play an insulating role between the heating component 20 and the heat pipe 40, thereby preventing the heating component 20 from being short-circuited by the heat pipe 40.
[0067] The first film segment 231 surrounds the outer side of the heat pipe 40, that is, only one layer of the heat insulating film is arranged between the heating component 20 and the heat pipe 40. While achieving insulation between the heating component 20 and the heat pipe 40, since only one layer is arranged, the influence on the heat transfer between the heating component and the heat pipe 40 is small.
[0068] The second film segment 232 surrounds the outer side of the heat pipe 40 at least three times, so that the second film segment 232 can form at least three layers of heat insulation on the outer side of the heating component 20, avoiding the heat generated by the heating component 20 from leaking out and reducing heat loss. The second film segment 232 has at least three layers. After the multi-layer winding, the heat insulation film can stand up in its width direction, which is convenient for subsequent assembly.
[0069] The heat-insulating film may be a PI film (polyimide film), which has good thermal conductivity, insulation, adhesion, and radiation resistance, and can be used for a long time within the temperature range of the smoking device.
[0070] See also Figure 5 During the manufacturing process, the heating component 20 can be first placed on the thermal insulation film, and the width of the heating component 20 is b; the thermal insulation film has a first length edge in its length direction; the distance between the heating component 20 and the first length edge is a; wherein a>b, during the rolling process, the heating component 20 and the first length edge form the first film segment 231, and the other parts form the second film segment 232.
[0071] The embodiment of the present application further provides an electronic smoking device 100, which includes a heating module 10. The heating module 10 adopts a part of the technical solutions of the above embodiments, or all of the technical solutions, and thus has the technical advantages or all of the technical advantages of the above embodiments.
[0072] The heating module and the electronic cigarette device provided in the embodiments of the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of the present application. At the same time, for technicians in this field, according to the idea of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
