Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.
[0042] Heat-not-burn is a technology that uses a special heating device to heat a special "cartridge" or "cigarette" to a low temperature to release smoke, avoiding the generation of toxic and harmful substances by high-temperature combustion, while being able to experience close to the taste and flavor of a cigarette. The technical solution of heat-not-burn heating uses a thin steel sheet to etch a loop, and adheres the loop to the outer wall of a metal tube, and the heat generated by the resistance wire is transmitted to the metal tube, and then the metal tube heats the cigarette. However, in this technical solution, the part of the cigarette that can generate heat is generally heated as a whole, resulting in slow heating efficiency. When a user uses an electronic smoking device to smoke an electronic cigarette, the user needs to wait for a long time before smoking after placing the cigarette in the electronic smoking device, resulting in a poor user experience.
[0043] Please refer to Figures 2 to 7 The embodiment of the present application provides a heating module 10, which comprises a heating assembly 20 and a separation piece 23. The heating assembly 20 comprises a first heating unit 21 and a second heating unit 22 arranged in sequence along a first direction, wherein the heating rate of the first heating unit 21 is higher than that of the second heating unit 22; and the separation piece 23 is at least sleeved on the outer side of the heating assembly 20.
[0044] The embodiment of the present application divides the heating assembly 20 into the first heating unit 21 and the second heating unit 22, wherein the heating rate of the first heating unit 21 is higher than that of the second heating unit 22. Therefore, when a user smokes using an electronic smoking device 100, the cigarette 1 can be placed in the electronic smoking device 100, and the first heating unit 21 can be used to quickly heat a local part of the cigarette 1 when the heating assembly 20 is used for heating. The separation piece 23 can be used to insulate the heating assembly 20, thereby reducing heat loss of the heating assembly 20, quickly generating the first puff of smoke, reducing the waiting time of the user for the first puff of smoke, and compared with the whole heating solution, the solution of the present application has a fast heating rate and can quickly generate the first puff of smoke for the user.
[0045] It should be noted that the first heating unit 21 and the second heating unit 22 are sequentially arranged in the first direction, which can be arranged in close proximity in the first direction, or can be arranged in a spaced manner, which is not limited herein. The specific implementation form of the first heating unit 21 and / or the second heating unit 22 is not limited, which can be in the form of a heating net, a printed circuit, a carbon fiber heating body, etc. The specific implementation form is not limited herein. The heating rate of the first heating unit 21 is higher than that of the second heating unit 22. The specific implementation form is not limited, which can be that the first heating unit 21 has a larger heating power, or when the heating power of the first heating unit 21 and the second heating unit 22 is the same, the heating area of the first heating unit 21 is smaller, etc. The specific implementation form is not limited herein.
[0046] The heating rate refers to the length of time for heating the cigarette 1 from room temperature to the smoking temperature. For example, the longer the time for heating the cigarette 1 from room temperature to the smoking temperature, the slower the heating rate, and vice versa. The shorter the time, 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, both must be opened or closed at the same time. Therefore, in a further embodiment, the first heating unit 21 and the second heating unit 22 are arranged in parallel. In the technical solution of the present embodiment, the first heating unit 21 and the second heating unit 22 can be independently controlled by arranging them in parallel, and each can be independently turned on and off.
[0048] Further, in an embodiment, the first heating unit 21 and the second heating unit 22 alternately heat. In this way, only one heating unit in the heating module 10 heats at a time, so that the power supply of the electronic smoking set 100 only needs to supply power to one of the first heating unit 21 and the second heating unit 22 during heating. Correspondingly, the heating power of the first heating unit 21 and the second heating unit 22 can be made consistent with or almost the same as the heating power of the existing whole-section heating heating unit, so that the original heating power for heating the whole section now only heats the local part, greatly improving the smoking efficiency of the cigarette 1.
[0049] Specifically, the initial resistance value of the heating unit needs to be as small as possible under the premise of safety. For example, when a commonly used 18650 series battery is used, the resistance value can be configured to be between 0.4Ω and 1Ω.
[0050] Further, the first heating unit 21 and the second heating unit 22 can be independently arranged, so that the short circuit between the first heating unit 21 and the second heating unit 22 can be effectively avoided.
[0051] In an 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 in a spaced manner, and the second pin 212 and the fourth pin 222 are arranged in an integrated manner.
[0052] In this way, since the second pin 212 and the fourth pin 222 are arranged in an integrated manner, they are connected together, and the resistance value at the pins is small, so that the heat generation at the pins is small, and the heat can be concentrated at the part that needs to be heated.
[0053] Further, in order to smoke more quickly, the temperature rising rate of the first heating unit 21 is more than twice the temperature rising 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 generate the first puff, and after the first puff is generated, the first heating unit 21 and the second heating unit 22 can be alternately heated to heat different parts of the cigarette 1.
[0054] It should be emphasized that the temperature rising rate of the first heating unit 21 is more than twice the temperature rising rate of the second heating unit 22, which can be that the temperature rising rate of the first heating unit 21 is twice, three times, four times, etc. the temperature rising rate of the second heating unit 22.
[0055] Specifically, in an embodiment, the heating power of the first heating unit 21 and the second heating unit 22 is consistent, and the first heating unit 21 is a resistance wire, and at this time, the heating rate of the first heating unit 21 is the fastest.
[0056] In addition, the heating positions of the first heating unit 21 and the second heating unit 22 on the cigarette 1 are not limited, which can be that one heats the head of the part that needs to be heated of the cigarette 1, and the other heats the tail of the cigarette 1. Specifically, the first heating unit 21 can heat the head of the part that needs to be heated of the cigarette 1, and the second heating unit 22 can heat the tail of the cigarette 1, or the second heating unit 22 can heat the head of the part that needs to be heated of the cigarette 1, and the first heating unit 21 can heat the tail of the cigarette 1, which is not limited herein.
[0057] Please refer toFigure 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 close to the filter section and a second smoking section 12. In an embodiment, when the heating assembly 20 is used to heat the cigarette 1, the first heating unit 21 is used to heat the part of the cigarette 1 close to the filter, and the second heating unit 22 is used to heat the part of the cigarette 1 away from the filter. In this way, the part heated by the first heating unit 21 is close to the filter, and after smoking, the distance between the smoke and the filter is short, so that the user can quickly inhale the smoke. Specifically, the first heating unit 21 is used to heat the first smoking section 11, so that the first smoking section 11 smokes quickly.
[0058] Further, the heating assembly 20 has no specific implementation form and can be a heating net, a carbon fiber heating body or a printed circuit, etc. Specifically, the carbon fiber heating body is a tubular heating body made of carbon fiber as a basic heating material. The heating body utilizes a reflecting surface to dissipate heat, and the electric heating conversion rate is above 95%. Compared with nickel-chromium and tungsten-molybdenum materials as the heating body, the energy saving rate is 30%. When the isolation member 23 is a PI film, the heating assembly 20 can also be a printed circuit, so that the printed circuit is printed on the PI film. After printing, the PI film is wound outside the heat conductor, and the heating module is formed.
[0059] In an embodiment, the heating assembly 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. The first heating net includes a plurality of first electrically resistive wires 213 arranged at intervals, and the second heating net includes a plurality of second electrically resistive wires 223 arranged at intervals.
[0060] In the technical scheme of the embodiment, the first heating unit 21 is arranged as a first heating net, the second heating unit 22 is arranged as a second heating net, and each heating net includes a plurality of electrically resistive wires. Therefore, compared with the scheme of a single electrically resistive wire, the heating uniformity can be improved by arranging a plurality of electrically resistive wires.
[0061] In a further embodiment, the gap between the plurality of first electrically resistive wires 213 is smaller than the gap between the plurality of second electrically resistive wires 223. In this way, the density of the electrically resistive wires of the first heating unit 21 is higher, and the temperature rising rate is also higher.
[0062] Alternatively, the cross-sectional area of the first electrically resistive wire 213 is smaller than the cross-sectional area of the second electrically resistive wire 223. In this way, the resistance value of the first electrically resistive wire 213 is greater than the resistance value of the second electrically resistive wire 223, so that the temperature rising rate of the first heating unit 21 is faster.
[0063] Further, the first resistance wire 213 has a width of 0.2-2 mm, and the first resistance wire 213 is an austenitic stainless steel piece. 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 is not too high, and the cigarette 1 is prevented from being scorched, thereby affecting the quality of the smoke.
[0064] In addition, the heating module 10 further comprises a heat-conducting pipe 40, the heat-conducting pipe 40 has an insertion channel 41 adapted to insert the cigarette 1; the heating assembly 20 is arranged outside the heat-conducting pipe 40; the isolation piece 23 comprises a heat-insulating and insulating film, the heat-insulating and insulating film comprises a first film segment 231 located between the heat-conducting pipe 40 and the heating assembly 20 and a second film segment 232 located outside the heating assembly 20; wherein the first film segment 231 surrounds the outside of the heat-conducting pipe 40 for one turn, and the second film segment 232 surrounds the outside of the heat-conducting pipe 40 for at least three turns.
[0065] In the technical scheme of the present embodiment, the heating assembly 20 is arranged outside the heat-conducting pipe 40, so that the heat emitted by the heating assembly 20 can be transmitted to the cigarette 1 by the heat-conducting pipe 40 to heat the cigarette 1, and the heat-conducting pipe 40 can play a role in heat conduction and heat equalization.
[0066] It can be understood that the heat-conducting pipe 40 can be a metal pipe or a plastic pipe, which is not limited herein. When the heat-conducting pipe 40 is a metal pipe, the first film segment 231 can play a role in insulation between the heating assembly 20 and the heat-conducting pipe 40, thereby preventing the heating assembly 20 from being short-circuited by the heat-conducting pipe 40.
[0067] The first film segment 231 surrounds the outside of the heat-conducting pipe 40 for one turn, that is, only one layer of heat-insulating and insulating film is arranged between the heating assembly 20 and the heat-conducting pipe 40, so that the heat-insulating and insulating film can play a role in insulation between the heating assembly 20 and the heat-conducting pipe 40, and at the same time, since only one layer of heat-insulating and insulating film is arranged, the heat-insulating and insulating film has less influence on heat transfer between the heating assembly and the heat-conducting pipe 40.
[0068] The second film segment 232 surrounds the outside of the heat-conducting pipe 40 for at least three turns, so that the second film segment 232 can form at least three layers of heat insulation outside the heating assembly 20, thereby preventing heat generated by the heating assembly 20 from leaking out and reducing heat loss. In addition, the second film segment 232 has at least three layers, and after being wound in multiple layers, the heat-insulating and insulating film can stand up in the width direction, thereby facilitating subsequent assembly.
[0069] The heat insulation film can be a PI film (polyimide film) which has good thermal conductivity, insulation, adhesion, radiation resistance, and can be used for a long time in the temperature range of the heating of the smoking set.
[0070] Please refer to Figure 5 In the production process, the heating component 20 can be placed on the heat insulation film at first, the width of the heating component 20 is b; the heat insulation film has a first length edge in the length direction; the distance between the heating component 20 and the first length edge is a; wherein a > b, in the rolling process, the part of the heating component 20 and the first length edge forms the first film segment 231, and the other part forms the second film segment 232.
[0071] The electronic smoking set 100 provided by the embodiment of the present application also has the technical advantages of the heating module 10.
[0072] The heating module and the electronic smoking set provided by the embodiment of the present application are introduced in detail above, and the principle and implementation mode of the present application are described by applying specific examples in this paper; the above embodiment is only used to help understand the method of the present application and its core idea; meanwhile, for the person skilled in the art, according to the idea of the present application, the specific implementation mode and application range will be changed; in conclusion, the content of the specification should not be understood as the limitation of the present application.
