Description

Technical Field

[0001] The present invention relates to the technical field of non-combustion heating, and particularly to a non-combustion heating device and a heating method thereof.

Background Art

[0002] A heat-not-burning (HNB) device mainly heats a tobacco product at a temperature lower than the temperature that causes combustion, generates an aerosol containing nicotine or other components during heating, and allows a user to inhale it. Compared with conventional cigarettes, the function of the heat-not-burning device is not to burn tobacco, but to sufficiently heat the tobacco product to generate an aerosol. Therefore, in order to prevent the generation of harmful substances, the heating temperature of the heat-not-burning device should not be too high, and in order to avoid the inability to generate an aerosol, the heating temperature should not be too low.

[0003] In a heat-not-burning device, usually, a heating element with a metal circuit printed on ceramic is used. After being energized, the tobacco product is heated by the heat generated by the Joule effect, and the heating element is usually built into the central position of the tobacco product. The heating temperature and heating time of the central position and the peripheral position of the tobacco product are different. On the one hand, the central part is likely to be overheated, resulting in a burnt flavor in the later stage of heating, releasing harmful substances, or the peripheral part is likely to be underheated, unable to generate an aerosol, causing waste of the tobacco product. On the other hand, there is a possibility of wasting energy to the central part, with low energy utilization efficiency and short continuous use time of the entire device.

Summary of the Invention

[0004] The main technical problem to be solved by the present invention is to provide a non-combustion heating device and a heating method thereof for improving the heating uniformity, energy utilization efficiency, and continuous use time of the non-combustion heating device.

[0005] According to a first aspect, an embodiment is A housing having a containment chamber for containing aerosol products, A heating element, wherein a plurality of heating elements are provided, and the plurality of heating elements are uniformly provided on the wall of the containment chamber for piercing the aerosol product, The present invention provides a non-combustion heating device, which includes a control assembly mounted on the housing and electrically connected independently to each of the heating elements, the control assembly configured to independently control the heating of each of the heating elements.

[0006] In one selectable embodiment, the containment chamber extends in a first direction, the plurality of heating members are arranged in the first direction, and the control assembly is configured to sequentially control the independent heating of each of the heating members in the first direction.

[0007] In one selectable embodiment, the heating element includes a plurality of heating teeth for piercing the aerosol product, the heating teeth having an end and a toothed portion, the end being fixed to the wall of the containment chamber and electrically connected to the control assembly, and the toothed portion protruding from the end for piercing the aerosol product.

[0008] In one selectable embodiment, the multiple heating teeth are spaced apart in a second direction, the second direction being perpendicular to the first direction.

[0009] In one selectable embodiment, in the same heating element, two adjacent heating teeth are arranged offset in the second direction.

[0010] In one selectable embodiment, the wall of the housing chamber is provided with mounting seats corresponding one-to-one with the heating teeth, and the heating teeth are electrically connected to the control assembly via the corresponding mounting seats. The mounting seat includes a first mounting seat and a second mounting seat arranged at intervals, and the end includes a first connecting end and a second connecting end, the first connecting end being connected to the first mounting seat and the second connecting end being connected to the second mounting seat.

[0011] In one selectable embodiment, the housing includes an upper lid and a lower lid, the upper lid is provided with a first housing recess, and the lower lid is provided with a second housing recess, and when the first housing recess and the second housing recess are joined together, the housing chamber is formed. The housing includes a first magnetic member provided on the upper lid and a second magnetic member provided on the lower lid, and the first magnetic member and the second magnetic member attract each other, thereby tightening the upper lid and the lower lid together.

[0012] In one selectable embodiment, the heating element is provided on both the upper lid and the lower lid. The control assembly includes a first control unit mounted on the upper cover and a second control unit mounted on the lower cover, the first control unit and the second control unit being electrically connected via a conductive connection structure. The conductive connection structure includes a conductive hole and a conductive column that fits into the conductive hole, wherein the conductive hole is provided in either the upper cover or the lower cover, and the conductive column is provided in the other of the upper cover or the lower cover.

[0013] According to the second embodiment, The steps include obtaining the current cumulative heating time and total suction time of a non-combustion heating device, The steps include analyzing and calculating the current cumulative heating time and the total suction time, and determining the calculation result, Based on the calculation results, the steps include determining the conditions and parameters of the target heating element that needs to be involved in the heating process, The present invention provides a heating method for a non-combustion heating device, which includes the step of controlling the heating of each of the target heating elements.

[0014] In one selectable embodiment, the step of determining the conditions and parameters of the target heating element that needs to be involved in heating, based on the calculation results, If the ratio of the current cumulative heating time to the total suction time is 1 / N or less, then the first heating element among the N heating elements arranged sequentially in the first direction is determined to be the target heating element involved in the heating process. If the ratio of the current cumulative heating time to the total suction time exceeds (n-1) / N and is less than or equal to n / N, then the nth heating element among the N heating elements arranged sequentially in the first direction is determined to be the target heating element involved in the heating process. If the ratio of the current cumulative heating time to the total suction time exceeds n / N and is less than (n+1) / N, then the (n+1)th heating element among the N heating elements sequentially arranged in the first direction is determined to be the target heating element involved in the heating process. The method includes determining the number of target heating elements involved in heating to be zero if the ratio of the current cumulative heating time to the total suction time is equal to 1. The first direction is the longitudinal direction of the aerosol product, N is the total number of heating elements, and n is a positive integer less than N.

Because the heating element can penetrate the aerosol product, the contact area between the heating element and the aerosol product can be increased, contributing to improved heating uniformity of the aerosol product, reduced variations in heating temperature of different parts of the aerosol product, and reduced occurrence of burnt flavor and wasted aerosol product in the later stages of heating. Furthermore, since the control assembly can independently control the heating of each of the heating elements, it becomes easy to sequentially control the heating of one or more heating elements individually based on the analytical calculation results of the cumulative heating time and total suction time. This shortens the heating time of a single heating element and the heating time of some of the aerosol product corresponding to each heating element, avoids overheating of some of the aerosol product, prevents energy waste, and contributes to improving the overall energy utilization rate and continuous operating time of the device.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, the present invention will be described in more detail in combination with specific embodiments and drawings. In different embodiments, similar parts are assigned related similar reference numerals. Many of the detailed descriptions in the following embodiments are for facilitating the understanding of this application. However, those skilled in the art can easily recognize that some of its features can be omitted under different circumstances, or replaced by other parts, materials, and methods. In some cases, in order to prevent the core part of this application from being obscured by excessive explanations, although some operations related to this application are not described or explained in the specification, those skilled in the art do not have to explain those related operations in detail, and based on the description in the specification and the general technical knowledge in this field, they can fully understand those related operations.

[0019] Also, the characteristics, operations, or features described in the specification can be combined in any appropriate way to form various embodiments. At the same time, each step or operation in the description of the method can be changed or adjusted in an obvious way for those skilled in the art. Therefore, the various orders in the specification and drawings are merely for clearly explaining specific embodiments, and do not indicate an essential order unless otherwise stated as essential.

[0020] In this specification, the numbers such as "First," "Second," etc., assigned to the components are used solely to distinguish the subjects described and do not have any order or technical meaning. Furthermore, in this application, "connection" and "linking" include both direct and indirect connections (linking) unless otherwise specified.

[0021] Referring to Figures 1 to 7, this application discloses a non-combustion heating device 100. The device comprises a housing 10, heating members 50, and a control assembly 30, the housing 10 having a containment chamber 101 for containing aerosol products (which may be tobacco products such as tobacco sticks or loose tobacco), the heating members 50 being mounted on the housing 10 and protruding from the wall of the containment chamber 101 to pierce the aerosol products, a plurality of heating members 50 being provided and uniformly arranged on the wall of the containment chamber 101, and the control assembly 30 being mounted on the housing 10 and electrically connected independently to each heating member 50, and configured to allow independent control of the heating of each heating member 50.

[0022] Since the heating element 50 can pierce the aerosol product, the contact area between the heating element 50 and the aerosol product can be increased, improving the uniformity of heating of the aerosol product, reducing variations in heating temperature across different parts of the aerosol product, and contributing to reducing the occurrence of burnt flavor and waste of the aerosol product in the later stages of heating.

[0023] Furthermore, the non-combustion heating device 100 can independently control the heating of each heating element 50, and for example, one or more heating elements 50 can be sequentially controlled individually based on the analytical calculation results of the cumulative heating time and total suction time. Here, cumulative heating time refers to the cumulative heating time of the heating elements 50 in one suction cycle, and total suction time is the total heating time that ensures all aerosol products filled in the containment chamber 101 are sufficiently heated and no toxic substances are generated, based on the volume size of the containment chamber 101. The total suction time can be said to be determined according to the volume size of the containment chamber 101. For example, as the ratio of cumulative heating time to total suction time increases in stages, the control assembly 30 can sequentially control the independent heating of one or two of the multiple heating elements 50 in stages, and when the ratio reaches 1, the heating of all heating elements 50 and heating of all aerosol products is completed. In this way, the heating time of a single heating element 50 and the heating time of some aerosol products corresponding to each heating element 50 can be shortened. As a result, overheating of some aerosol products can be avoided, energy waste can be prevented, and the overall energy utilization rate and continuous operating time of the device can be improved.

[0024] Specifically, in some embodiments, the containment chamber 101 may be a containment hole extending in a first direction, and the heating members 50 are arranged continuously or at intervals in the first direction, the first direction being the longitudinal direction of the non-combustion heating device 100. The control assembly 30 can sequentially control the independent heating of each heating member 50 in the first direction according to the magnitude of the ratio of cumulative heating time to total suction time. For example, as the ratio increases in stages, the independent heating of one heating member 50 at a time can be controlled in stages in the first direction, and when the ratio reaches 1, heating of all heating members 50 and heating of all aerosol products is completed. This makes it possible to simulate the actual smoking process, ensuring that some of the aerosol products corresponding to each heating member 50 are sufficiently heated while overheating is avoided, further improving energy utilization and the user experience.

[0025] In one embodiment, the heating element 50 includes a plurality of heating teeth 501 spaced apart in a second direction, the second direction being the width direction of the non-combustion heating device 100 and perpendicular to the first direction, and each heating tooth 501 is positioned extending in the first direction, with two adjacent heating teeth 501 offset in the second direction, thereby uniformly distributing the heating teeth 501 on the wall surface of the housing chamber 101 and contributing to improving the overall heating uniformity of the non-combustion heating device 100.

[0026] Referring to Figures 2, 3, 5, and 6, there may be three heating teeth 501, which are spaced apart in the second direction, with the heating tooth 501 in the middle position being offset in the second direction relative to the heating tooth 501 at the end position.

[0027] The number of heating elements 50 is not limited to three, but may be two, four, or five or more. Furthermore, in the case of a large number of heating teeth 501, the multiple heating teeth 501 can be arranged in rows and columns in the first and second directions, respectively, in order to achieve a uniform arrangement on the side wall of the housing chamber 101.

[0028] Furthermore, each heating tooth 501 in the heating member 50 can be aligned in a second direction, provided that two adjacent heating members 50 are continuous in a first direction or are positioned close to each other. Alternatively, in some other embodiments, the heating member 50 may further include heating wires uniformly laid on the wall surface of the containment chamber 101, the heating wires having protrusions for piercing the aerosol product.

[0029] In some embodiments, referring again to Figures 2, 3, 5, and 6, the heating tooth 501 has a slender structure, and the longitudinal direction of the heating tooth 501 is oriented in the same direction as the first direction. The heating tooth 501 has an end 502 and a toothed portion 503, the end 502 of the heating tooth 501 is fixed to the wall of the containment chamber 101 and electrically connected to the control assembly 30, and the toothed portion 503 of the heating tooth 501 is provided to project from the end 502 for piercing the aerosol product. The end 502 of the heating tooth 501 includes a first connecting end 5021 and a second connecting end 5022 located at both ends in the first direction, and the toothed portion 503 of the heating tooth 501 is fixedly connected between the first connecting end 5021 and the second connecting end 5022 and projects toward the center of the containment chamber 101 to form a piercing tip for piercing the aerosol product. The piercing tip contributes to increasing the depth to which the heated teeth 501 penetrate the aerosol product, thereby increasing the contact area between the heated teeth 501 and the aerosol product and improving the uniformity of heating of the aerosol product by the heated teeth 501.

[0030] In some other embodiments, to increase the contact area between the heating teeth 501 and the aerosol product, a plurality of branching structures may be further provided between the first connecting end 5021 and the second connecting end 5022, the plurality of branching structures project toward the center of the containment chamber 101 and form short teeth for engaging with the aerosol product.

[0031] In some embodiments, referring to Figures 2 and 5, the wall of the housing chamber 101 is provided with mounting seats 6 that correspond one-to-one with the heating teeth 501. The housing chamber 101 is formed by joining a first housing recess 11 and a second housing recess 21 in a third direction, and the third, second, and first directions are orthogonal to each other. The end face of the mounting seat 6 facing inward into the housing chamber 101 in the third direction is neither higher nor lower than the wall surface of the housing chamber 101. The heating teeth 501 are electrically connected to a control assembly 30 provided in the housing 10 via the corresponding mounting seat 6. The heating teeth 501 can be manufactured from materials such as nichrome alloy, iron-chromium alloy, or stainless steel, and the mounting seat 6 can be manufactured from low-resistance materials such as copper alloy, silver-palladium alloy, or pure gold.

[0032] The mounting seat 6 includes a first mounting seat 61 and a second mounting seat 62 spaced apart in a first direction, the first mounting seat 61 being a low-pressure mounting seat and the second mounting seat 62 being a high-pressure mounting seat, the first connecting end 5021 of the heating tooth 501 being fixedly connected to the first mounting seat 61 and the second connecting end 5022 being fixedly connected to the second mounting seat 62, and when both ends of the heating tooth 501 communicate with the high-pressure mounting seat and the low-pressure mounting seat, respectively, a resistor for heating the aerosol product is formed, and by controlling the power supplied to the heating tooth 501, the heating temperature of the heating tooth 501 can be controlled to satisfy an appropriate heating temperature for the aerosol product.

[0033] In some other embodiments, the heating element 50 may further include a plurality of heating rods, which are spaced apart in a second direction, with one end of each heating rod being a connecting end and the other end being a heating end, the heating rods penetrating the wall of the containment chamber 101, the connecting end located inside the housing 10 and electrically connected to the control assembly 30, and the heating end penetrating the wall of the containment chamber 101 and protruding inward to engage with the aerosol product.

[0034] In some embodiments, the heating element 50 includes a pair of first heating elements 51 and second heating elements 52, which are arranged alternately in a first direction, i.e., a structure in which three or more heating elements 50 are provided, wherein a second heating element 52 is provided between two adjacent first heating elements 51, and a first heating element 51 is provided between two adjacent second heating elements 52.

[0035] Referring to Figures 2, 3, 5, and 6, in the first heating member 51, the first connection ends 5021 of the multiple heating teeth 501 are located on the side of the second connection ends 5022 facing the second heating member 52 in the first direction. This facilitates the connection between the first connection ends 5021 of the heating teeth 501 in the first heating member 51 and the first connection ends 5021 of the heating teeth 501 in the second heating member 52, reducing the number of first mounting seats 61 provided in the housing 10. Furthermore, it facilitates the electrical connection of the first mounting seat 61 corresponding to the first heating member 51 and the first mounting seat 61 corresponding to the second heating member 52 in the housing 10, thereby reducing the number of wires connecting the first mounting seats 61 and the control assembly 30.

[0036] Accordingly, the first connection ends 5021 of the multiple heating teeth 501 in the second heating member 52 may be positioned on the side of the second connection end 5022 facing the first heating member 51 in the first direction. This makes it easier to connect multiple first connection ends 5021 to the same first mounting seat 61, or to electrically connect multiple first mounting seats 61, and also contributes to reducing the number of first mounting seats 61 provided on the housing 10, or the number of wires connecting the first mounting seats 61 to the control assembly 30.

[0037] Of course, in other embodiments, the heating elements may be arranged such that two adjacent first heating elements 51 constitute a first heating group and two adjacent second heating elements 52 constitute a second heating group, with the first heating group and the second heating group being arranged alternately in the first direction, i.e., the two first heating elements 51 and the two second heating elements 52 being arranged alternately in the first direction. In such a structure, in adjacent first heating members 51 and second heating members 52, the first connecting ends 5021 of some heating teeth 501 in the first heating member 51 may be positioned on the opposite side of the second connecting end 5022 from the second heating member 52 in the first direction, and the first connecting ends 5021 of some heating teeth 501 in the second heating member 52 may be positioned on the opposite side of the second connecting end 5022 from the first heating member 51 in the first direction. As a result, two adjacent first heating members 51, or two adjacent second heating members 52, will have first connecting ends 5021 that are close to each other, and as a result, it will be easy to connect multiple first connecting ends 5021 in the first heating member 51 to the same first mounting seat 61, or to electrically connect multiple first mounting seats 61 corresponding to the first heating member 51.

[0038] In some embodiments, referring to Figures 2, 3, 5, and 6, the first heating member 51 is provided with three heating teeth 501, and the heating tooth 501 in the intermediate position in the second direction is positioned closer to or further away from the second heating member 52 in the first direction, thereby achieving a staggered arrangement of two adjacent heating teeth 501 in the first heating member 51 in the second direction. Correspondingly, the second heating member 52 is also provided with three heating teeth 501, and the heating tooth 501 in the intermediate position in the second direction is positioned closer to or further away from the first heating member 51 in the first direction, thereby achieving a staggered arrangement of two adjacent heating teeth 501 in the second direction.

[0039] Furthermore, the heating teeth 501 are arranged such that at least two adjacent heating teeth 501 have their first connecting ends 5021 connected in the first direction and connected to the same first mounting seat 61. Referring to Figures 5 and 6, these two adjacent heating teeth 501 may be a heating tooth 501 located at an intermediate position in the second direction on the first heating member 51 and a heating tooth 501 located at an intermediate position in the second direction on the second heating member 52, or, referring to Figure 3, these two adjacent heating teeth 501 may be a heating tooth 501 located at the end position in the second direction on the first heating member 51 and a heating tooth 501 located at the end position in the second direction on the second heating member 52. Such an arrangement contributes to reducing the number of mounting seats 6 provided on the wall of the housing chamber 101, and also reduces the number of wires connecting the mounting seats 6 to the control assembly 30.

[0040] In some embodiments, the first connection ends 5021 of multiple heating teeth 501 on the same heating element 50, i.e., multiple heating teeth 501 in the second direction, are located on the same side as the second connection ends 5022, and the first mounting seats 61 corresponding to these heating teeth 501 are also located on the same side as the second mounting seats 62, thereby facilitating the electrical connection of multiple first mounting seats 61 corresponding to the same heating element 50, and reducing the length and number of wires connecting the first mounting seats 61 to the control assembly 30 without affecting the independent heating of each heating element 50.

[0041] In an embodiment in which adjacent heating teeth 501 belonging to two heating members 50, i.e., the first connecting ends 5021 of two heating teeth 501 arranged in a first direction, are close to each other, the multiple first mounting seats 61 corresponding to the two adjacent heating members 50 are electrically connected, thereby reducing the length and number of wires connecting the first mounting seats 61 and the control assembly 30 without affecting the independent heating of each heating member 50.

[0042] Referring to Figures 4 and 7, in Figure 4, in adjacent first heating member 51 and second heating member 52, the four first mounting seats 61 connected to the first connection end 5021 of the six heating teeth 501 are connected by short connections and then connected to the control assembly 30 via the same connecting wire. In Figure 7, in adjacent first heating member 51 and second heating member 52, of the five first mounting seats 61 connected to the first connection end 5021 of the six heating teeth 501, two first mounting seats 61 are connected by short connections and then connected to the control assembly 30 via one connecting wire, and the remaining three first mounting seats 61 are similarly connected by short connections and then connected to the control assembly 30 via the same connecting wire.

[0043] In embodiments where the orientation of the first connection end 5021 and the second connection end 5022 of each heating tooth 501 coincides within the same heating element 50, as shown in Figures 4 and 7, the second mounting seat 62 corresponding to each heating tooth 501 can also be electrically connected to the control assembly 30 via one or two wires after electrical connection, thereby reducing the length and number of wires connecting the mounting seat 6 and the control assembly 30 without affecting the independent control of each heating element 50.

[0044] Of course, this structure, which connects multiple first mounting seats 61 and then connects them to the control assembly 30 with a single wire, is also applicable to embodiments in the same heating member 50 where the relative positions of the first connection ends 5021 and the second connection ends 5022 of two adjacent heating teeth 501 in the second direction do not coincide. Furthermore, it is also applicable to embodiments in which, of two adjacent heating teeth 501 belonging to different heating members 50, the first connection end 5021 of one heating tooth 501 is located on the side of the second connection end 5022 that is away from the other heating tooth 501. This structure, which connects multiple second mounting seats 62 and then connects them to the control assembly 30 with one or two wires, is also applicable to embodiments in the same heating member 50 where the orientation of the first connection ends 5021 and the second connection ends 5022 of different heating teeth 501 does not coincide.

[0045] Of course, to prevent a poor connection in any one of the wires connecting the mounting base 6 and the control assembly 30 from affecting the operation of multiple heating teeth 501, it is also possible to ensure relative independence between each heating tooth 501 by providing a high-voltage connection wire and a low-voltage connection wire corresponding to the mounting base 6 of each heating tooth 501.

[0046] In some embodiments, referring to Figure 2, the non-combustion heating device 100 includes an upper lid 1 and a lower lid 2, which are rotatably connected via pivot shafts provided at their respective ends, for example, a hinge connection is employed. A first accommodating recess 11 is provided at the end of the upper lid 1 away from the pivot shaft, and a second accommodating recess 21 is provided at the end of the lower lid 2 away from the pivot shaft. The first accommodating recess 11 and the second accommodating recess 21 can be joined together facing each other during rotation of the upper lid 1 and the lower lid 2 to form a accommodating chamber 101 for arranging aerosol products, and heating members 50 are provided on both the walls of the first accommodating recess 11 and the walls of the second accommodating recess 21.

[0047] The housing 10 is provided with an engagement structure between the upper lid 1 and the lower lid 2. Specifically, this engagement structure includes a first magnetic member 13 provided on the upper lid 1 and a second magnetic member 23 provided on the lower lid 2. After the upper lid 1 and the lower lid 2 are joined together, the first magnetic member 13 and the second magnetic member 23 attract each other, tightening the upper lid 1 and the lower lid 2, thereby preventing the upper lid 1 and the lower lid 2 from automatically loosening and falling out of the containment chamber 101.

[0048] Of course, in some other embodiments, the upper lid 1 and the lower lid 2 may be fixedly connected, in which case the aerosol product enters the containment chamber 101 through the opening of the containment chamber 101 at the longitudinal end of the housing 10 and the heating teeth 501 pierce the aerosol product.

[0049] In some embodiments, both the upper cover 1 and the lower cover 2 have a hollow shell structure, with the upper cover 1 having a first mounting chamber 14 inside and the lower cover 2 having a second mounting chamber 25 inside, the opening of the first housing recess 11 in the upper cover 1 being located on the rear side relative to the first mounting chamber 14, and the opening of the second housing recess 21 in the lower cover 2 being located opposite the second mounting chamber 25, the control assembly 30 includes a first control unit 31 mounted in the first mounting chamber 14 and a second control unit 32 mounted in the second mounting chamber 25, each control unit including an electrically connected PCB bridge board 301 and an IC module, a plurality of mounting seats 6 provided on the wall of the housing chamber 101 being connected to the corresponding PCB bridge board 301 via connecting wires, and the IC module being used to control the independent heating of each heating element 50 in the corresponding upper cover 1 or lower cover 2.

[0050] Referring to Figures 2, 3, 5, and 6, the first control unit 31 and the second control unit 32 are electrically connected via a conductive connection structure, which includes a conductive column 12 provided on the upper cover 1 and a conductive groove 22 provided on the lower cover 2. The conductive column 12 is electrically connected to the first control unit 31, and the conductive groove 22 is electrically connected to the second control unit 32. After the upper cover 1 and the lower cover 2 are joined together, the conductive column 12 and the conductive groove 22 fit together, thereby achieving the electrical connection between the first control unit 31 and the second control unit 32.

[0051] Furthermore, a power module 5 is provided in the second mounting chamber 25 of the lower cover 2, and the power module 5 is electrically connected to the second control unit 32 inside the lower cover 2. The power module 5 includes a charging connector 24 provided at the end of the lower cover 2 in the longitudinal direction of the housing 10, and the charging connector 24 is connected to an external power source and used to charge the non-combustion heating device 100.

[0052] In some embodiments, referring to Figure 1, in the non-combustion heating device 100, the outer shape of the upper lid 1 is generally rectangular, and the edges and corners of the upper lid 1 can be rounded. Similarly, the outer shape of the lower lid 2 is also generally rectangular, and the edges and corners of the lower lid 2 can also be rounded. This prevents the user from being injured by sharp parts on the outer surfaces of the upper lid 1 and lower lid 2. When the upper lid 1 and lower lid 2 are joined together, a housing 10 is formed. The housing 10 has a generally rectangular cross-sectional shape in its longitudinal direction, and the corners of the rectangular cross-sectional shape can be rounded.

[0053] The opening of the housing hole, formed by the opposite fusion of the first housing recess 11 and the second housing recess 21, is located at the end of the housing 10 in the longitudinal direction of the housing 10. A mouthpiece 4 is further provided at one end of the housing 10 in the longitudinal direction. The mouthpiece 4 has a first end opening and a second end opening 41 at both ends of the housing 10 in the longitudinal direction, the first end opening and the second end opening 41 are in communication with each other, and the mouthpiece 4 is fitted to the end of the housing 10 via the first end opening. The first end opening of the mouthpiece 4 is in communication with the opening of the housing hole. As a result, the aerosol generated in the housing hole is inhaled by the user sequentially through the opening of the housing hole, the first end opening, and the second end opening 41. The cross-sectional outer shape of the end of the mouthpiece 4 having the first end opening is generally rectangular, and the edges and corners of the end of the mouthpiece 4 are rounded. The shape of the first end opening may also be rectangular, and the shape of the first end opening matches the outer shape of the end of the housing 10. The mouthpiece 4 is made of silicone material, and the first end opening of the mouthpiece 4 is fitted to the outside of the housing 10 to achieve a fixed connection with the housing 10. The shape of the second end opening 41 is circular, and the overall cross-sectional dimensions of the second end are set to be smaller than those of the first end so that the user can easily put the second end opening 41 in their mouth.

[0054] In one embodiment, during use of the non-combustion heating device 100, the heating teeth 501 pierce the aerosol product, and based on the current cumulative heating time and total heating time of the non-combustion heating device 100, one or more heating members 50 located at different positions in the longitudinal direction of the housing 10 are controlled to be heated sequentially under appropriate temperature conditions, and when the cumulative heating time reaches the total suction time, all heating members 50 complete one heating cycle. In this way, on the one hand, it is possible to ensure that each part of the aerosol product arranged in the longitudinal direction of the containment chamber 101 is heated sufficiently and uniformly, without the generation of burnt flavor or harmful substances, and it is also possible to prevent a single heating member 50 from overheating, and on the other hand, it is possible to avoid energy waste, effectively increase energy utilization efficiency, and improve the continuous operating time of the entire non-combustion heating device 100.

[0055] This application further discloses a heating method for a non-combustion heating device 100 in any of the embodiments described above. Referring to Figure 8, the heating method is as follows: Step S1 involves obtaining the current cumulative heating time and total suction time of a non-combustion heating device, Step S2 involves analyzing and calculating the current cumulative heating time and total suction time, and determining the calculation results. Step S3 determines the conditions and parameters of the target heating element that needs to be involved in heating based on the calculation results, The method includes step S4, which controls the heating of each target heating element.

[0056] In some embodiments, in step S1 above, the cumulative heating time refers to the cumulative heating time of the heating element 50 during a single suction, and the total suction time may be the total heating time that ensures all aerosol products filled in the containment chamber 101 are sufficiently heated and no toxic substances are generated, based on the volume size of the containment chamber 101. The control assembly 30 of the non-combustion heating device 100 obtains the cumulative heating time and total suction time.

[0057] In step S2 described above, the control assembly 30 analyzes and calculates the current cumulative heating time and total suction time, and obtains a calculation result. This analysis may involve calculating the ratio of the current cumulative heating time to the total suction time, or it may simply involve determining whether the current cumulative heating time exceeds a set cumulative heating time. The set cumulative heating time is shorter than the total suction time and is set by the user according to the usage situation. For example, the set cumulative heating time can be 1 / 2, 1 / 3, or 2 / 3 of the total suction time.

[0058] In step S3 described above, the control assembly 30 continues to determine the conditions and parameters of the target heating element that need to be involved in heating, based on the calculation results in step S2. The conditions may be the positional conditions of the target heating element, for example, the first element sequentially arranged along the longitudinal direction of the containment chamber 101, the first and second elements adjacent to each other, or multiple elements distributed at intervals. If multiple heating elements 50 are provided in the second direction, the positional conditions of the target heating element may be the first element sequentially arranged in the second direction, the first and second elements, or multiple elements distributed at intervals. The parameters of the target heating element may be its number or heating power. The number of target heating elements may be one or more, and the heating power may be the total power of multiple heating elements 50 heated simultaneously, or the power of a single heating element 50.

[0059] The location, number, and power of the target heating elements that need heating can be determined based on the ratio of the current cumulative heating time to the total suction time, and the location, number, and power of the target heating elements that need heating can also be determined based on whether the current cumulative heating time exceeds the set cumulative heating time. The power can be determined individually according to the cumulative heating time; for example, the power may gradually increase with increasing cumulative heating time, or it may gradually increase and then gradually decrease with increasing cumulative heating time.

[0060] Finally, in step S4, the control assembly 30 controls the heating of the target heating element determined in step S3.

[0061] Thus, a method that allows sequential heating of different positions and different numbers of heating elements 50 based on cumulative heating time and total suction time contributes to shortening the heating time of a single heating element 50 and the heating time of some aerosol products corresponding to each heating element 50, avoiding overheating and energy waste of some aerosol products, and improving heating efficiency, energy utilization rate, and continuous operating time of the non-combustion heating device 100.

[0062] In some embodiments, referring to Figure 9, step S3 determines the conditions and parameters of the target heating element that needs to be involved in heating based on the calculation results. If the ratio of the current cumulative heating time to the total suction time is 1 / N or less, step S31 is performed to determine the first heating member among the N heating members arranged sequentially in the first direction as the target heating member involved in the heating process. Step S32 is performed in which, if the current cumulative heating time and total suction time ratio exceeds (n-1) / N and is less than or equal to n / N, the nth heating member out of the N heating members arranged sequentially in the first direction is determined to be the target heating member involved in the heating process. Step S33 is performed in which, if the current cumulative heating time and total suction time ratio exceeds n / N and is less than (n+1) / N, the (n+1)th heating element among the N heating elements sequentially arranged in the first direction is determined to be the target heating element involved in the heating process. Step S34 includes determining the number of target heating elements involved in heating to be zero if the ratio of the current cumulative heating time to the total suction time is equal to 1. The first direction is the longitudinal direction of the aerosol product, N is the total number of heating members 50, and n is a positive integer less than N.

[0063] The calculation result is the ratio of the current cumulative heating time to the total suction time, and the conditions and parameters of the target heating element are the positional conditions and numerical parameters of the target heating element, respectively.

[0064] In one example, the total number N of heating members 50 is set to two, that is, the first heating member 51 and the second heating member 52 are arranged in the longitudinal direction of the aerosol product, and the number and length of heating teeth 501 in each heating member 50 are equal. When determining the ratio of cumulative heating time to total suction time, if the cumulative heating time is less than or equal to half of the total suction time, the first heating member 51, which is further away from the suction port 4 in the first direction, is determined as the target heating member involved in heating, and heating of the first heating member 51 is started, while the second heating member 52 is kept in a non-heated state. If the cumulative heating time exceeds half of the total suction time and the ratio is less than 1, the second heating member 52, which is closer to the suction port 4 in the first direction, is determined as the target heating member involved in heating, and heating of the second heating member 52 is controlled to maintain the first heating member 51, or to adjust the first heating member 51 to a non-heated state. If the cumulative heating time is equal to the total heating time, it means that all aerosol products have been sufficiently heated and all heating members 50 have completed one heating cycle, and at this time, heating of all heating members 50 is stopped.

[0065] Of course, in other embodiments, the total number N of heating members 50 may be three or more. When the number of heating members 50 is set to three, two first heating members 51 and a second heating member 52 located between them can be installed, and the number and length of heating teeth 501 in each heating member 50 are equal. If the cumulative heating time is 1 / 3 or less of the total heating time, only one of the first heating members 51 is determined as the target heating member to start heating. If the cumulative heating time exceeds 1 / 3 of the total heating time and is 2 / 3 or less of the total heating time, only the second heating member 52 is determined as the target heating member to start heating. If the cumulative heating time exceeds 2 / 3 of the total heating time and is less than the total heating time, only the other first heating member 51 is determined as the target heating member to start heating. If the cumulative heating time is equal to the total heating time, it means that all aerosol products have been sufficiently heated and all heating members 50 have completed one heating cycle, and at this time, heating of all heating members 50 is stopped.

[0066] This allows for the simulation of the actual smoking process, enabling independent heating of aerosol products in each part along the first direction, and ensuring that the heating time for each part is equal. This prevents the generation of harmful substances due to localized overheating of aerosol products, and also prevents situations where some aerosol products are not heated and therefore unable to generate aerosols. As a result, the flavor during inhalation is improved, heating efficiency and energy utilization are increased, and the continuous operating time of the non-combustion heating device 100 is extended.

[0067] The present invention has been explained above using specific examples, but these are merely to aid in understanding the invention and do not limit it in any way. Those skilled in the art may make some simple inferences, modifications, or substitutions based on the concept of the present invention. [Explanation of symbols]
