Description

Technical Field

[0001] This application relates to the technical field of heat-not-burn atomization, and particularly relates to a heating structure and a heat-not-burn atomization device. Background Art

[0002] A heat-not-burn atomization device is a device that can heat an aerosol-forming substrate in a heat-not-burn manner. When using a heating structure to heat the aerosol-forming substrate, different heating temperatures will have different heating effects on the aerosol-forming substrate. Therefore, it is very necessary to monitor and control the heating temperature of the aerosol-forming substrate to better ensure the heating effect on the aerosol-forming substrate.

[0003] Currently, most temperature control methods are achieved through the resistance-temperature relationship characteristics of heating materials. However, for heating elements with a small resistance temperature, it is not suitable to use the resistance-temperature relationship characteristics to achieve temperature control. For example, when the heating structure uses electromagnetic heating, the heating element is a magnetic material and has a small resistance temperature coefficient, so it cannot achieve temperature control through the resistance-temperature relationship characteristics of the heating material.

[0029] The present application will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners are labeled with related similar reference numerals. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods.

For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0030] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment and do not mean a necessary sequence, unless it is stated otherwise that a certain sequence must be followed.

[0031] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).

[0032] Please refer to Figures 1-8 , in an embodiment of the present application, a heating structure is provided, including: a receiving member 10, a heating member 20, an auxiliary temperature measuring body 40, and a temperature measuring member 50.

[0033] An insertion opening is formed at the top 11 of the receiving member 10, and the insertion opening is used for the aerosol-forming matrix A to be inserted into the receiving member 10. A part of the heating member 20 passes through the bottom 12 of the receiving member 10 and is placed inside the receiving member 10, and the heating member 20 is used to insert the aerosol-forming matrix A.

[0034] The auxiliary temperature measuring body 40 is fixed inside the heating member 20 and is in thermal contact with the heating member 20 to achieve heat transfer. The temperature measuring member 50 is fixed to the auxiliary temperature measuring body 40 and is used to measure the temperature of the auxiliary temperature measuring body 40.

[0035] With the heating structure in the above embodiment, the auxiliary temperature measuring body 40 is fixed inside the heating member 20 and is in contact with the heating member 20 to achieve heat transfer. At this time, by measuring the temperature on the auxiliary temperature measuring body 40 through the temperature measuring member 50, the heating temperature provided by the heating member 20 to the aerosol-forming matrix A can be indirectly measured, and thus it is convenient to control the temperature of the heating member with a small resistance temperature coefficient.

[0036] Please refer to Figure 1 or Figure 8 , the heating structure further includes a coil 30, the coil 30 is arranged outside the receiving member 10, and the coil 30 is used to cooperate with the heating member 20 to heat the aerosol-forming matrix A in a manner of electromagnetic induction heating. At this time, the heating member 20 cooperating with the coil 30 has a small induction resistance and a small resistance temperature coefficient. However, with the heating structure designed as above, the temperature of the heating member 20 can be controlled, that is, the temperature control of the heating structure using the electromagnetic heating method can be achieved.

[0037] It should be noted that the coil 30 is an electromagnetic coil, and the heating element 20 is a magnetic material with a certain magnetic permeability, such as iron, graphite, stainless steel, etc. When the coil 30 passes an alternating current to generate an alternating magnetic field, it will heat the heating element 20 with a certain magnetic permeability.

[0038] Specifically, the heating element 20 is provided with a hollow interior. The heating element 20 is similar to a hollow tube structure. An air inlet 211 and an air outlet 212 are formed on the heating element 20. The air inlet 211 is connected to the outside, and the part of the heating element 20 where the air inlet 211 is located is outside the storage member 10, while the air outlet 212 is located on the part of the heating element 20 inside the storage member 10. After the coil 30 is powered on, it heats the heating element 20. The heat generated by the heating element 20 can, on the one hand, directly heat the aerosol-forming substrate A in contact therewith, and on the other hand, heat the air flowing into the heating element 20 through the air inlet 211. The heated air flows through the air outlet 212 into the aerosol-forming substrate A, thereby realizing the indirect heating of the aerosol-forming substrate A by the heating element 20. That is to say, the designed heating element 20 has two heating methods: direct heating and indirect heating, and the heating element 20 can fully heat the aerosol-forming substrate A. Due to the heat conduction effect of the auxiliary temperature measuring body 40, the temperature difference between the auxiliary temperature measuring body 40 and the heating element 20 is very small. Therefore, by measuring the temperature of the auxiliary temperature measuring body 40 with the temperature measuring member 50, the heating temperature provided by the heating element 20 to the aerosol-forming substrate A can be indirectly measured.

[0039] Specifically, the storage member 10 is a storage cup or a storage cylinder. The specific structure of the storage member 10 will be described in the form of the storage cylinder as the storage member 10. The top 11 of the storage member 10 corresponds to the cylinder mouth, that is, the so-called insertion port. A storage cavity is formed inside the storage member 10, and the storage cavity is used to store the aerosol-forming substrate A. The bottom 12 of the storage member 10 corresponds to the cylinder bottom, which can provide a certain supporting force and a limiting effect on the aerosol-forming substrate A inserted into the storage cavity. The bottom 12 of the storage member 10 is provided with an opening so that the heating member 20 can pass through. To ensure the heating effect of the heating member 20 on the aerosol-forming substrate A, the heating member 20 and the storage member 10 are coaxially arranged so that the heating member 20 can be inserted into the center of the aerosol-forming substrate A. To facilitate the flow of air, a plurality of air inlets 211 and a plurality of air outlets 212 can be provided on the heating member 20. The caliber of the air inlet 211 and the caliber of the air outlet 212 can be the same or different. The number of the air inlets 211 and the number of the air outlets 212 can be the same or different. For example, two air inlets 211 and six air outlets 212 are provided on the heating member 20. The two air inlets 211 are symmetrically distributed on the heating member 20. The six air outlets 212 are divided into three pairs of air outlets 212. Each pair of air outlets 212 is symmetrically distributed on the heating member 20. The three pairs of air outlets 212 are spaced along the axial direction of the heating member 20. The settings of the air inlet 211 and the air outlet 212 are only listed here and should not be construed as a limitation to this application. Specifically, they can be flexibly set according to the actual air intake and air outlet requirements.

[0040] Among them, the temperature measuring member 50 is a thermocouple or a thermistor, and the heating structure further includes a lead wire 60. Taking the thermocouple as an example, when the temperature measuring member 50 is a thermocouple, the thermocouple can be welded and fixed on the auxiliary temperature measuring body 40. One end of the thermocouple is connected to the lead wire 60, and the other end of the lead wire 60 is used to connect to the temperature control element. The thermocouple and the temperature control element cooperate to control the temperature of the heating structure. The temperature control element is, for example, the control board 110.

[0041] To ensure the heat conduction effect and the temperature measurement accuracy of the auxiliary temperature measuring body 40, the material of the auxiliary temperature measuring body 40 can specifically be aluminum alloy, copper alloy, cast iron, silver-plated copper, etc. These listed materials also have a certain strength, which can ensure the structural strength of the designed auxiliary temperature measuring body 40. The heating member 20 for inserting into the aerosol-forming substrate A itself has a small volume, so the auxiliary temperature measuring body 40 located inside the heating member 20 also has a small volume. Combined with the heat conduction performance of the auxiliary temperature measuring body 40, the auxiliary temperature measuring body 40 can have a fast heat conduction speed and can achieve a uniform heat conduction effect, which is convenient for ensuring the temperature measurement accuracy of the temperature measuring member 50 and further ensuring the temperature control effect of the heating structure.

[0042] Preferably, the thermal conductivity of the auxiliary temperature measuring body 40 is greater than that of the heating element 20. Thus, on the one hand, the thermal conductivity of the auxiliary temperature measuring body 40 can be accelerated, and on the other hand, the hysteresis of the temperature measurement can be reduced to ensure the temperature measurement effect of the temperature measuring element 50. For example, in one embodiment, the heating element 20 is 430 stainless steel, and the auxiliary temperature measuring body 40 is 6063 aluminum alloy.

[0043] See also Figures 1-2 The heating element 20 includes a heating main body tube 21 and a tapered portion 22. The heating main body tube 21 is provided with an air inlet 211 and an air outlet 212. The tapered portion 22 is fixed to one end of the heating main body tube 21 facing the top 11 of the storage element 10. The design of the tapered portion 22 facilitates the insertion of the heating element 20 into the aerosol-forming matrix A. The tapered portion 22 may be a solid structure or a hollow structure.

[0044] See also Figures 3-7 In some embodiments, the auxiliary temperature measuring body 40 includes an auxiliary temperature measuring body 41 and at least one supporting rib 42. The supporting rib 42 is fixed to the auxiliary temperature measuring body 41, and the number of the supporting ribs 42 can be 1, 2, 3, 4, 5, etc. The supporting ribs 42 can support the auxiliary temperature measuring body 41 and ensure the installation stability of the auxiliary temperature measuring body 41 in the heating element 20. The supporting ribs 42 fixed on the auxiliary temperature measuring body 41 will divide the space in the heating element 20, so that the supporting ribs 42 can extend the flow path of the airflow entering the heating element 20. When the flow path of the airflow flowing into the heating element 20 becomes longer, the heat exchange effect of the airflow in the heating element 20 can be enhanced, so that the airflow is fully heated. The heated airflow is referred to as hot airflow, and the hot airflow flows into the aerosol forming matrix A through the air outlet 212 as the user sucks the aerosol forming matrix A. Since the hot air flow can be fully heated in the heating element 20, combined with the heat conduction effect of the auxiliary temperature measuring body 40, the temperature on the heating element 20, the temperature on the auxiliary temperature measuring body 40 and the temperature of the hot air flow are not much different as a whole. At this time, the temperature on the auxiliary temperature measuring body 40 is measured by the temperature measuring element 50, and the heating temperature provided by the heating structure to the aerosol forming matrix A can be obtained more accurately. It can be understood that, in order to facilitate processing and assembly, the auxiliary temperature measuring body 41 and the support rib 42 are an integrated structure, and in order to facilitate the overall thermal conductivity uniformity of the auxiliary temperature measuring body 40, the auxiliary temperature measuring body 41 and the support rib 42 are made of the same material.

[0045] See also Figure 8, the temperature measuring element 50 is fixed to the auxiliary temperature measuring main body 41. Along the axial direction of the heating element 20, the air inlet 211 is located between the temperature measuring element 50 and the bottom 12 of the receiving element 10. That is, along the axial direction of the heating element 20, the temperature measuring element 50 and the air inlet 211 are staggeredly distributed. In this way, when the external air flow enters the heating element 20 through the air inlet 211, the air flow that has not been heated in time can avoid the temperature measuring element 50, preventing the air flow that has not been heated in time from interfering with the temperature measurement accuracy of the temperature measuring element 50. At the same time, the temperature measuring element 50 is located on the auxiliary temperature measuring main body 41 below the air inlet 211, and the temperature measuring element 50 and the support rib 42 can also be staggeredly distributed, facilitating the assembly and fixation of the temperature measuring element 50.

[0046] Please refer to Figures 3-6 , specifically, in one embodiment, the auxiliary temperature measuring main body 41 is an auxiliary temperature measuring plate, and the support ribs 42 are configured in multiple numbers. Along the axial direction of the heating element 20, the multiple support ribs 42 are fixedly spaced on both sides of the auxiliary temperature measuring plate. The multiple support ribs 42 are, for example, 2, 3, 4, 6, etc. The auxiliary temperature measuring plate divides the space (i.e., the air flow channel) inside the heating element 20 into two sub-spaces. The multiple support ribs 42 are fixedly spaced on both sides of the auxiliary temperature measuring plate, which can at least ensure that there is one support rib 42 in each sub-space, thereby extending the flow path of the air flow in the sub-space. For example, when the support ribs 42 are configured as 2, one support rib 42 can be provided on each side of the auxiliary temperature measuring plate. For example, when the support ribs 42 are configured as 3, one or two support ribs 42 can be provided on one side of the auxiliary temperature measuring plate, and two or one support rib 42 can be provided on the other side of the auxiliary temperature measuring plate. One of the purposes of the support ribs 42 is to extend the flow path of the air flow inside the heating element 20. Therefore, based on this purpose, at least one support rib 42 in each sub-space of the heating element 20 is relatively farther away from the tapered portion 22 of the heating element 20 than the air outlet 212.

[0047] The support rib 42 is in the shape of a plate, and the plate surface of the support rib 42 is perpendicular or inclined to the plate surface of the auxiliary temperature measuring plate. For example, as Figures 3-5 shown, the plate surface of the support rib 42 is perpendicular to the plate surface of the auxiliary temperature measuring plate, or, for example, as Figure 6 shown, the plate surface of the support rib 42 is inclined to the plate surface of the auxiliary temperature measuring plate. When the plate surface of the support rib 42 is inclined to the plate surface of the auxiliary temperature measuring plate, the support rib 42 can have a larger plate surface area inside the heating element 20, thereby enabling a more sufficient heat exchange effect between the support rib 42 and the air flow inside the heating element 20.

[0048] Please refer to Figures 3-4, more specifically, the support rib 42 is in the shape of a plate. The plate surface of the support rib 42 is perpendicular to the plate surface of the auxiliary temperature measuring plate, and the plate surface of the support rib 42 is parallel to the axis of the heating element 20. A guide plate 421 is provided on one side of the support rib 42 facing the top 11 of the receiving member 10. From the side close to the top 11 of the receiving member 10 to the side away from the bottom 12 of the receiving member 10, the width of the guide plate 421 gradually increases. The width direction of the guide plate 421 is perpendicular to the axial direction of the heating element 20. The guide plate 421 is used to guide the auxiliary temperature measuring body 40 when it enters the heating element 20, so as to facilitate the loading of the auxiliary temperature measuring body 40 into the heating element 20.

[0049] Preferably, when the tapered portion 22 of the heating element 20 is a hollow structure, the shape of the top end of the auxiliary temperature measuring plate is adapted to the internal shape of the tapered portion 22. For example, when the tapered portion 22 is a tapered hollow structure, the shape of the top end of the auxiliary temperature measuring plate is also tapered, so as to facilitate the insertion of the auxiliary temperature measuring plate into the middle position in the heating element 20 and divide the space in the heating element 20 into two symmetrically distributed sub-spaces. Under the action of the auxiliary temperature measuring plate, the two sub-spaces are two relatively independent sub-spaces, and the airflows in the two sub-spaces do not flow into each other, so that the airflows in the sub-spaces are heated and then discharged through the air outlet 212 in time.

[0050] Preferably, the plurality of support ribs 42 are configured as multiple pairs of support ribs 42, that is, the number of support ribs 42 is an even number, and each pair of support ribs 42 is symmetrically distributed on both sides of the auxiliary temperature measuring plate. When the support ribs 42 are symmetrically distributed in pairs on both sides of the auxiliary temperature measuring plate, on the one hand, it can provide balanced support force for the auxiliary temperature measuring plate to prevent the auxiliary temperature measuring plate from tilting in the heating element 20. On the other hand, the symmetrically distributed support ribs 42 can enable the airflows in the two sub-spaces of the heating element 20 to obtain a relatively consistent heat exchange effect, so that the hot airflows can provide a relatively uniform heating effect for the aerosol forming matrix A. For example, as Figure 3 shown, the support ribs 42 are configured as 4, and two pairs of support ribs 42 are spaced apart on the auxiliary temperature measuring plate. The number of the support ribs 42 is only listed here and can be flexibly set according to the specific situation, and should not be construed as a limitation to this application. The shape of the support ribs 42 can be rectangular, triangular, semi-circular or other special shapes, as long as it can meet the function of the support ribs 42, and the specific shape of the support ribs 42 is not limited.

[0051] Please refer to Figure 7, specifically, in another embodiment, the auxiliary temperature measuring body 41 is an auxiliary temperature measuring tube. Avoidance openings 411 are provided at positions corresponding to the air inlet 211 and the air outlet 212 to ensure the air flow at the air inlet 211 and the air outlet 212. The diameter of the avoidance opening 411 can be larger than the diameter of the air inlet 211 to avoid affecting the air flow rate at the air inlet 211. The diameter of the avoidance opening 411 can be larger than the diameter of the air outlet 212 to avoid affecting the air flow rate at the air outlet 212. The diameter of the air inlet 211 can be larger than the diameter of the air outlet 212, so that the air inlet 211 can obtain a larger air flow rate, and the air outlet 212 can discharge hot air with a greater flow velocity.

[0052] The auxiliary temperature measuring tube is sleeved inside the heating element 20 (the heating main tube 21), and the outer wall of the auxiliary temperature measuring tube is in contact with the heating element 20. A plurality of support ribs 42 are configured. Along the axial direction of the auxiliary temperature measuring tube, the plurality of support ribs 42 are fixedly spaced apart on opposite sides of the inner wall of the auxiliary temperature measuring tube. The support ribs 42 are plate-shaped, and the plate surface area of the support ribs 42 is smaller than the radial cross-sectional area of the inner wall of the auxiliary temperature measuring tube, so that a gap is left between the support ribs 42 and the inner wall of the auxiliary temperature measuring tube to facilitate the passage of air flow. Among them, the radial cross-sectional area of the auxiliary temperature measuring tube is perpendicular to the axis of the auxiliary temperature measuring tube. When the plurality of support ribs 42 are fixedly spaced apart on the same side of the inner wall of the auxiliary temperature measuring tube, an unobstructed channel is easily formed on the other side of the inner wall of the auxiliary temperature measuring tube, which is not conducive to extending the flow path of the air flow in the heating element 20 and cannot ensure the heat exchange efficiency of the air flow. Therefore, the plurality of support ribs 42 are fixedly spaced apart on opposite sides of the inner wall of the auxiliary temperature measuring tube.

[0053] The plurality of support ribs 42 can be 2, 3, 4, etc. at this time. The shapes of the plurality of support ribs 42 can be the same or different. For Figure 7 example, the auxiliary temperature measuring tube is a circular tube, and the support ribs 42 are configured as 3 at this time. The 3 support ribs 42 can be 1 / 4 circular plates, 1 / 2 circular plates or 3 / 4 circular plates respectively. The support ribs 42 are perpendicular or inclined to the axis of the auxiliary temperature measuring tube. The specific number, shape and distribution mode of the support ribs 42 are flexibly selected according to actual needs, and the present application does not limit them.

[0054] Among them, the plurality of support ribs 42 can be configured as multiple pairs of support ribs 42, and each pair of support ribs 42 is symmetrically distributed on both sides of the inner wall of the auxiliary temperature measuring tube. The sum of the plate surface areas of each pair of support ribs 42 is smaller than the radial cross-sectional area of the inner wall of the auxiliary temperature measuring tube, that is, a gap for the air flow to pass through is left between each pair of support ribs 42 to avoid blocking the air flow.

[0055] Please refer to Figure 8, Specifically, the heating structure further includes a sleeve 70, a nozzle 80, a bracket 90, and a base 100. The sleeve 70 is sleeved outside the storage member 10 and is spaced apart from the storage member 10. An annular groove is formed on the sleeve 70, and the coil 30 is sleeved in the annular groove. The nozzle 80 is fixed to the head end 71 of the sleeve 70, and the storage member 10 is fixed to the nozzle 80. A through hole 81 is formed on the nozzle 80 to facilitate the aerosol-forming matrix A to pass through. After passing through the through hole 81, the aerosol-forming matrix A is inserted into the storage member 10 through the insertion port. The bracket 90 is fixed to the tail end 72 of the sleeve 70, the base 100 is fixed to one end of the bracket 90 facing the sleeve 70, and a part of the structure of the heating element 20 is fixed on the base 100. There is a spaced space between the base 100 and the bottom 12 of the storage member 10, and the air inlet 211 is disposed in this spaced space. When the user inhales the aerosol-forming matrix A, the external air flow can flow, for example, from the mouthpiece to the space between the sleeve 70 and the storage member 10, then flow to the spaced space, and flow into the heating element 20 through the air inlet 211.

[0056] In the heating structure designed in the above embodiment of the present application, the auxiliary temperature measuring body 40 is fixed in the heating element 20, the temperature measuring member 50 is fixed on the auxiliary temperature measuring body 40, and the auxiliary temperature measuring body 40 can transfer the temperature of the heating element 20 to the temperature measuring member 50. The temperature of the heating element 20 can be controlled by the temperature feedback from the temperature measuring member 50. The heating structure measures the temperature in a physical contact manner, which is convenient for ensuring the accuracy of temperature measurement and further ensuring the temperature control effect. Moreover, the designed heating structure is simple and easy to process.

[0057] Please refer to Figure 1 , In another embodiment of the present application, a heat-not-burn atomizing device is provided, which includes a control board 110 and the heating structure in the above embodiment. The temperature measuring member 50 is electrically connected to the control board 110 through a lead wire 60, and the control board 110 is used to control the heating temperature of the heating structure according to the temperature information measured by the temperature measuring member 50.

[0058] The heat-not-burn atomizing device further includes a power supply 120 and a housing 130. The power supply 120 is electrically connected to the coil 30 and the control board 110 respectively, and the power supply 120 is used to provide an alternating current to the coil 30.
