Description

Technical Field

[0001] The present application relates to the technical field of novel tobacco products, and in particular to a heating component, a heating element component and a heating device. Background Art

[0002] As the e-cigarette industry gradually becomes standardized, heated cigarettes are also gradually becoming market-oriented. Heated cigarettes mainly include cigarettes and matching heating devices. Among them, electric heating devices bake cigarettes by electric heating to make the cigarettes produce smoke. Existing heated cigarette devices usually use central heating or peripheral heating.

[0003] For peripheral heating, a cylindrical or tubular heating element is generally used. When in use, the cigarette is inserted into the cavity of the heating element and then powered on for heating. However, this heating method has problems such as slow heating rate, hot smoke and cigarette holder, continuous baking of tobacco materials and poor taste, and uneven smoke volume from puff to puff, which will affect the user's smoking experience.

[0004] The heating element is one of the core components of heated smoking devices. It plays a decisive role in the release and utilization of heat and the stable release of smoke. It is the basis of software control design, so its innovative design is very important. Summary of the invention

[0005] Based on this, it is necessary to provide a heating component, a heating body component and a heating device that can improve the smoking experience of heated cigarettes in order to address the above problems.

[0006] The technical solution is as follows:

[0007] In a first aspect, a heat generating component is provided, comprising:

[0008] The first heating section;

[0009] A second heating section; the second heating section and the first heating section are arranged at intervals along the first direction, the length of the first heating section along the first direction is less than or equal to the length of the second heating section along the first direction; the first heating section and the second heating section are both arranged on the periphery of the cigarette;

[0010] A first electrode, the first electrode is electrically connected to the first heating segment and the second heating segment; and

[0011] Two second electrodes, the two second electrodes are electrically connected to the first heating segment and the second heating segment respectively.

[0012] In the above-mentioned heating component, the first heating section and the second heating section have the same first electrode, but different second electrodes, which enables the heating process of the first heating section and the heating process of the second heating section to be controlled independently of each other, and further enables the heating process of the first heating section and the second heating section to be controlled to control the heat generation of the heating component, so as to ensure the heating speed of the cigarette while avoiding excessively high temperature of the smoke and the cigarette holder due to excessive heat generation. The independently controlled first heating section and the second heating section are also conducive to realizing the zoned heating of the cigarette, which can not only avoid the deterioration of the smoke taste due to continuous baking of the cigarette, but also ensure the full heating of the cigarette and the uniformity of the amount of smoke generated by the cigarette during the user's inhalation. In addition, when the length of the first heating section in the first direction is less than the length of the second heating section, the energy emitted by the first heating section with a smaller area can heat the corresponding cigarette area more concentratedly, so that the relative cigarette area can generate smoke faster, so when the first heating section is arranged at one end close to the cigarette holder, the design of the first heating section can increase the smoke output speed and smoke volume of the first puff of smoke. Therefore, when the heating component is used to heat the cigarette, the user's smoking experience can be effectively improved.

[0013] The technical solution is further described below:

[0014] In one embodiment, the resistance of the first heating segment is equal to or greater than the resistance of the second heating segment.

[0015] In one embodiment, the first heating section includes a first high temperature section and a second high temperature section arranged along the first direction, the first high temperature section is located on a side of the second high temperature section away from the second heating section; the resistance of the first high temperature section is smaller than the resistance of the second high temperature section.

[0016] In one embodiment, along the first direction, the length of the first high temperature section is less than or equal to the length of the second high temperature section.

[0017] In one embodiment, the second heating section includes a third high temperature section and a fourth high temperature section arranged along the first direction, the third high temperature section is located on a side of the fourth high temperature section away from the first heating section; the resistance of the third low temperature section is smaller than the resistance of the fourth low temperature section.

[0018] In one embodiment, along the first direction, the length of the third high temperature section is equal to the length of the fourth high temperature section.

[0019] In a second aspect, a heating element assembly is provided, comprising:

[0020] The above-mentioned heating component;

[0021] A heat-conducting tube, wherein the heat-conducting tube is provided with a cavity and an insertion port communicating with the cavity, wherein the insertion port is used for inserting the cigarette into the cavity; the first heating section and the second heating section are both arranged on the outer periphery of the heat-conducting tube, and the second heating section is located on a side of the first heating section away from the insertion port; and,

[0022] A temperature sensor is connected to the first heating section.

[0023] In the above-mentioned heating element assembly, a heat pipe is arranged between the heating element and the cigarette, so that the heat generated by the heating element can be transferred to the cigarette through the heat pipe, thereby heating the cigarette. When the heating element assembly is used to heat the cigarette, the temperature sensor is connected to the first heating section, so that during the heating process of the heating element, the temperature sensor can monitor the temperature of the first heating section. The first heating section and the second heating section are arranged at intervals and controlled independently of each other, so that during the heating process of the heating element assembly, the temperature of the first heating section can be used as a reference to accurately regulate the heating process of the first heating section and the second heating section, so as to ensure the heating speed of the cigarette, and avoid the problem of smoke and scalding the mouth and deteriorating the taste of the smoke caused by continuous heating of each heating section and excessive heat generation of the heating element. The heating element assembly can also ensure the uniformity of cigarette heating and the uniformity of smoke volume by zone heating. In addition, when the length of the first heating section is smaller than that of the second heating section, the energy emitted by the first heating section with a smaller area can heat the corresponding cigarette area more concentratedly, so that the corresponding cigarette area can generate smoke faster. Therefore, the design of the first heating section can increase the smoke output speed and smoke volume of the first puff of cigarette. Therefore, when the heating element assembly is used to heat cigarettes, the user's smoking experience can be effectively improved.

[0024] In one of the embodiments, the heating element assembly further includes a fixing sleeve, and the fixing sleeve is sleeved on the outer circumference of the heating element assembly.

[0025] In one embodiment, the heating element further includes an insulating layer, and the insulating layer is located between the heat pipe and the heating component.

[0026] In a third aspect, a heating device is provided, which is formed with a accommodating cavity. The heating device includes a battery functional system, a circuit board and the above-mentioned heating element assembly. The battery functional system, the circuit board and the heating element assembly are all arranged in the accommodating cavity. The battery functional system is used to provide electrical energy to the circuit board, the first heating section, the second heating section and the temperature sensor. The circuit board is electrically connected to the first electrode, the two second electrodes and the temperature sensor.

[0027] In the above-mentioned heating device, the battery function system can provide electrical energy to the circuit board and the first heating section, the second heating section, and the temperature sensor. The circuit board is electrically connected to the input electrode, the two output electrodes, and the temperature sensor. The circuit board can effectively control the heating process of the heating element component according to the feedback of the temperature sensor. Specifically, when the heating device is used to heat a cigarette, the temperature sensor is connected to the first heating section, so that during the heating process of the heating element component, the temperature sensor can monitor the temperature of the first heating section. The first heating section and the second heating section are arranged at intervals and controlled independently of each other, so that during the heating process of the heating element component, the temperature of the first heating section can be used as a reference to accurately control the heating process of the first heating section and the second heating section to ensure the heating speed of the cigarette, and avoid the problem of continuous heating of each heating section and excessive heat generation of the heating element, which causes the smoke and smoke to burn the mouth and the smoke taste to deteriorate. The heating element component can also ensure the uniformity of cigarette heating and the uniformity of smoke volume by zone heating. In addition, when the length of the first heating section is smaller than that of the second heating section, the energy emitted by the first heating section with a smaller area can heat the corresponding cigarette area more concentratedly, so that the corresponding cigarette area can generate smoke faster. Therefore, the design of the first heating section can increase the smoke output speed and smoke volume of the first puff of cigarette. Therefore, when using the heating device to heat cigarettes, the user's smoking experience can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] See also Figure 1 , Figure 1 The schematic diagram of the structure of the heating component 2 in one embodiment of the present application is shown. The heating component 2 provided in one embodiment of the present application includes a first heating section 21, a second heating section 22, a first electrode 6 and two second electrodes 7. Among them:

[0044] like Figure 1 As shown, the second heating segment 22 and the first heating segment 21 are arranged at intervals along the first direction, and the length of the first heating segment 21 along the first direction is less than or equal to the length of the second heating segment 22 along the first direction; the first heating segment 21 and the second heating segment 22 are both used to be arranged on the periphery of the cigarette. The first electrode 6 is electrically connected to both the first heating segment 21 and the second heating segment 22. The two second electrodes 7 are electrically connected to the first heating segment 21 and the second heating segment 22, respectively.

[0045] The polarities of the first electrode 6 and the second electrode 7 are different. For example, the first electrode 6 may be an input electrode 6 and the second electrode 7 may be an output electrode 7. Alternatively, the first electrode 6 may be an output electrode 7 and the second electrode 7 may be an input electrode 6.

[0046] For ease of description and understanding, the heating area corresponding to the first heating section 21 can be defined as the first temperature zone, and the heating area corresponding to the second heating section 22 can be positioned as the second temperature zone. When the heating component 2 is used to heat a cigarette, the second heating section 22 can be arranged on the side of the first heating section 21 away from the cigarette holder, that is, when the heating component 2 is used to heat a cigarette, the first temperature zone is closer to the cigarette holder than the second temperature zone.

[0047] like Figure 1 As shown, when the length of the first heating section 21 in the first direction is smaller than the length of the second heating section 22 in the first direction, the area of ​​the first temperature zone is smaller than that of the second temperature zone, so the heat in the first temperature zone is more concentrated than that in the second temperature zone. This is conducive to quickly increasing the heating temperature of the first temperature zone.

[0048] like Figure 1 As shown, the first temperature zone and the second temperature zone are arranged at intervals. This allows the cigarette portion corresponding to the area between the first heating section 21 and the second heating section 22 to be heated by heat conduction between the first temperature zone and the second temperature zone when the heating component 2 is used to heat the cigarette. This can not only fully utilize the heat of the heating component 2 to heat the cigarette, but also reduce the power consumption of the heating component 2.

[0049] In the above-mentioned heating component 2, the first heating section 21 and the second heating section 22 have the same first electrode 6, but different second electrodes 7, which enables the heating process of the first heating section 21 and the heating process of the second heating section 22 to be controlled independently of each other, and further enables the heating process of the first heating section 21 and the second heating section 22 to be controlled to control the heat generation of the heating component 2, so as to ensure the heating speed of the cigarette while avoiding excessive heat generation causing excessive temperature of the smoke and the cigarette holder. Independently controlled first heating section 21 and second heating section 22 are also conducive to realizing zoned heating of the cigarette, which can not only avoid the deterioration of smoke taste due to continuous baking of the cigarette, but also ensure sufficient heating of the cigarette and uniformity of the amount of smoke generated by the cigarette during the user's inhalation. In addition, when the length of the first heating section 21 in the first direction is smaller than the length of the second heating section 22, the energy emitted by the first heating section 21 with a smaller area can heat the corresponding cigarette area more concentratedly, so that the corresponding cigarette area can generate smoke faster. Therefore, when the first heating section 21 is arranged at one end close to the cigarette holder, the design of the first heating section 21 can increase the smoke output speed and smoke volume of the first puff of smoke. Therefore, when the heating component 2 is used to heat cigarettes, the user's smoking experience can be effectively improved.

[0050] In one embodiment, the resistance of the first heating segment 21 is equal to or greater than the resistance of the second heating segment 22. When the resistance of the first heating segment 21 is equal to the resistance of the second heating segment 22, and the same voltage is applied to the first heating segment 21 and the second heating segment 22, the heat generated by the first heating segment 21 is equal to the heat generated by the second heating segment 22. Since the area of ​​the first temperature zone is smaller than that of the second temperature zone, the first temperature zone can heat up faster than the second temperature zone, which is conducive to the first temperature zone reaching the target temperature of the heated cigarette faster and generating smoke faster. When the resistance of the first heating segment 21 is greater than that of the second heating segment 22, under the condition that the same voltage is applied to the first heating segment 21 and the second heating segment 22, although the heat generated by the first heating segment 21 will be less than that of the second heating segment 22, since the area of ​​the first temperature zone is smaller than that of the second temperature zone, the first temperature zone can still have a higher heating speed by regulating the size of the first temperature zone and the heat generated by the first heating segment 21, thereby ensuring the smoke output rate and smoke volume of the first puff of smoke. In addition, when the heat generation of the first heating section 21 is low, it can avoid the temperature of the first temperature zone being too high, which may cause the smoke and the cigarette holder to become hot, thereby improving the user's smoking experience. The reduction in the resistance of the heating component 2 is also conducive to reducing the power consumption of the heating component 2.

[0051] Furthermore, the first heating section 21 and the second heating section 22 may both be in a mesh shape. For example, the first heating section 21 may include a plurality of first heating wires, which intersect each other to form a heating mesh. The second heating section 22 may include a plurality of second heating wires, which intersect each other to form a heating mesh.

[0052] Optionally, the first heating wire and the second heating wire may be made of the same material or different materials.

[0053] In one embodiment, Figure 2As shown, the first heating section 21 includes a first high temperature section 211 and a second high temperature section 212 arranged along the first direction, and the first high temperature section 211 is located on the side of the second high temperature section 212 away from the second heating section 22. The resistance of the first high temperature section 211 is less than the resistance of the second high temperature section 212. When the first heating section 21 includes the first high temperature section 211 and the second high temperature section 212, and the resistance of the first high temperature section 211 is less than the resistance of the second high temperature section 212, the first temperature zone can be divided into the first high temperature zone and the second high temperature zone, and the temperature of the first high temperature zone will be higher than the temperature of the second high temperature zone, which is conducive to realizing the zone heating of the cigarette, ensuring the uniformity of the heating of the cigarette and the uniformity of the amount of smoke generated by the cigarette. Since the first high temperature zone is located on the side of the second high temperature zone away from the second heating section 22, it is also conducive to speeding up the speed at which the user draws the first puff of smoke. The first temperature zone is divided into the first high temperature zone and the second high temperature zone, which makes the corresponding heating area of ​​the first high temperature section and the second high temperature section smaller, and then the corresponding cigarette area can be heated in a concentrated manner to ensure the heating speed of the cigarette. In addition, dividing the first temperature zone can also prevent the heat in the first temperature zone from being too high, which may cause the smoke and the cigarette holder to be too hot.

[0054] In one embodiment, Figure 2 As shown, along the first direction, the length of the first high temperature section 211 is less than or equal to the length of the second high temperature section 212. Since the temperature of the first high temperature zone is higher than the temperature of the second high temperature zone, when the length of the first high temperature section 211 is less than or equal to the length of the second high temperature section 212, the heating speed of the first high temperature zone can be effectively improved, which is conducive to accelerating the speed at which the user draws the first puff of smoke. This is also conducive to ensuring the uniformity of the amount of smoke generated by the cigarette.

[0055] In one embodiment, Figure 2 As shown, the second heating section 22 includes a third high temperature section 222 and a fourth high temperature section 221 arranged along the first direction, and the third high temperature section 222 is located on the side of the fourth high temperature section 221 away from the first heating section 21; the resistance of the third low temperature section 222 is less than the resistance of the fourth low temperature section 221. When the second heating section 22 includes the third high temperature section 222 and the fourth high temperature section 221, and the resistance of the first high temperature section 211 is less than the resistance of the fourth high temperature section 221, the second temperature zone can be divided into the third high temperature zone and the fourth high temperature zone, and the temperature of the third high temperature zone will be higher than the temperature of the fourth high temperature zone, which is conducive to realizing the zoned heating of the cigarette, ensuring the uniformity of the cigarette heating and the uniformity of the amount of smoke generated by the cigarette.

[0056] In one embodiment, Figure 2As shown, along the first direction, the length of the third high temperature section 222 is equal to the length of the fourth high temperature section 221. When the length of the third high temperature section 222 is equal to the length of the fourth high temperature section 221, the area sizes of the third high temperature zone and the fourth high temperature zone can be roughly equal, which is conducive to fully heating the cigarette and ensuring the uniformity of the amount of smoke and the uniformity of the amount of smoke generated by the cigarette.

[0057] See also Figure 3 , Figure 3 The schematic diagram of the structure of the heating element assembly 100 in one embodiment of the present application is shown. The heating element assembly 100 provided in one embodiment of the present application comprises the heating element 2, the heat pipe 1 and the temperature sensor 5 in any of the above embodiments. Wherein:

[0058] like Figure 3 and Figure 4 As shown, the heat conducting tube 1 is provided with a cavity and an insertion port 11 connected to the cavity, and the insertion port 11 is used for inserting a cigarette into the cavity; the first heating section 21 and the second heating section 22 are both arranged on the outer periphery of the heat conducting tube 1, and the second heating section 22 is located on the side of the first heating section 21 away from the insertion port 11. The temperature sensor 5 is connected to the first heating section 21.

[0059] The first direction is the direction in which the cigarette is inserted into the cavity along the heat conducting tube 1, and the temperature sensor 5 is used to feed back the temperature of the first temperature zone so as to realize temperature control of the heating process according to the temperature of the first temperature zone.

[0060] Optionally, the temperature sensor 5 may be a PT1000 temperature sensor, or a thermocouple, or an NTC temperature sensor.

[0061] In the above-mentioned heating element assembly 100, the heat pipe 1 is arranged between the heating element 2 and the cigarette, so that the heat emitted by the heating element 2 can be transferred to the cigarette through the heat pipe 1, thereby heating the cigarette. When the heating element assembly 100 is used to heat the cigarette, the temperature sensor 5 is connected to the first heating section 21, so that during the heating process of the heating element 2, the temperature sensor 5 can monitor the temperature of the first heating section 21. The first heating section 21 and the second heating section 22 are arranged at intervals and controlled independently of each other, so that during the heating process of the heating element assembly 100, the temperature of the first heating section 21 can be used as a reference to accurately control the heating process of the first heating section 21 and the second heating section 22, so as to ensure the heating speed of the cigarette, and avoid the problem of the smoke and smoke burning the mouth and the deterioration of the smoke taste caused by the continuous heating of each heating section and the excessive heat of the heating element 2. The heating element assembly 100 can also ensure the uniformity of cigarette heating and the uniformity of smoke volume by zone heating. In addition, when the length of the first heating section 21 is smaller than the length of the second heating section 22, the energy emitted by the first heating section 21 with a smaller area can heat the corresponding cigarette area more concentratedly, so that the corresponding cigarette area can generate smoke faster. Therefore, the design of the first heating section 21 can increase the smoke output speed and smoke volume of the first puff of cigarette. Therefore, when the heating element assembly 100 is used to heat cigarettes, the user's smoking experience can be effectively improved.

[0062] In one embodiment, Figure 3 As shown, the heating element assembly 100 further includes a fixing sleeve 4, which is sleeved on the outer periphery of the heating element 2. The setting of the fixing sleeve 4 can fit the heating element 2 on the heat conducting tube 1, thereby ensuring that the heat generated by the heating element 2 can be transferred to the heat conducting tube 1, so as to heat the cigarette inserted in the heat conducting tube 1.

[0063] Optionally, the fixing sleeve 4 may be a PEEK heat shrinkable sleeve, which is a soft silicone sleeve that can make the heating component 2 fit better on the heat pipe 1, thereby improving the heat transfer efficiency.

[0064] In one embodiment, Figure 3 As shown, the heating element further includes an insulating layer 3, which is located between the heat pipe 1 and the heating component 2. The insulating layer 3 can isolate the current and prevent short circuit or failure due to current leakage, so as to ensure the safety and reliability of the heating element component 100.

[0065] Optionally, the insulating layer 3 should have the characteristics of excellent insulation performance, good heat resistance and good thermal conductivity, for example, it can be a PI insulating film.

[0066] like Figure 3As shown, the present application also provides a heating device (not shown in the figure), wherein the heating device is formed with a accommodating cavity (not shown in the figure), the heating device includes a battery functional system (not shown in the figure), a circuit board (not shown in the figure) and a heating element assembly 100 in any of the above embodiments, the battery functional system and the circuit board heating element assembly 100 are both arranged in the accommodating cavity, the battery functional system is used to provide electrical energy to the circuit board, the first heating section 21, the second heating section 22 and the temperature sensor 5, and the circuit board is electrically connected to the first electrode 6, the two second electrodes 7 and the temperature sensor 5.

[0067] In the above-mentioned heating device, the battery function system can provide electric energy to the circuit board and the first heating section 21, the second heating section 22, and the temperature sensor 5. The circuit board is electrically connected to the input electrode 6, the two output electrodes 7, and the temperature sensor 5. The circuit board can effectively control the heating process of the heating element assembly 100 according to the feedback of the temperature sensor 5. Specifically, when the heating device is used to heat a cigarette, the temperature sensor 5 is connected to the first heating section 21, so that the temperature sensor 5 can monitor the temperature of the first heating section 21 during the heating process of the heating element 2. The first heating section 21 and the second heating section 22 are arranged at intervals and controlled independently of each other, so that during the heating process of the heating element assembly 100, the temperature of the first heating section 21 can be used as a reference to accurately control the heating process of the first heating section 21 and the second heating section 22, so as to ensure the heating speed of the cigarette, and avoid the problem of the smoke and smoke burning the mouth and the deterioration of the smoke taste caused by the continuous heating of each heating section and the excessive heat of the heating element 2. The heating element assembly 100 can also ensure the uniformity of cigarette heating and the uniformity of smoke volume by zone heating. In addition, when the length of the first heating section 21 is smaller than the length of the second heating section 22, the energy emitted by the first heating section 21 with a smaller area can heat the corresponding cigarette area more concentratedly, so that the corresponding cigarette area can generate smoke faster. Therefore, the design of the first heating section 21 can increase the smoke output speed and smoke volume of the first puff of cigarette. Therefore, when using the heating device to heat cigarettes, the user's smoking experience can be effectively improved.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application.
