Description

Technical Field

[0001] This invention relates to the field of heat-not-burning technology, specifically to a heat-not-burning device and its heating method. Background Technology

[0002] Heated tobacco products (HNB) heat tobacco at a temperature below that that would cause combustion, creating an aerosol containing nicotine or other components for inhalation. Unlike traditional cigarettes, the function of a heated tobacco product is not to burn the tobacco, but to heat it thoroughly to produce an aerosol. Therefore, the heating temperature cannot be too high to avoid producing toxic substances, nor can it be too low to prevent the formation of an aerosol.

[0003] Heated tobacco products typically use heating elements made by printing metal circuits onto ceramic. When powered on, they utilize the Joule effect to generate heat, typically positioned at the center of the tobacco product. The heating temperature and duration differ between the central and peripheral areas. On one hand, the central area is prone to overheating, leading to a burnt taste and the release of toxic substances later in the heating process; conversely, the peripheral areas may be underheated, resulting in insufficient aerosol production and wasted tobacco. On the other hand, the central area may experience energy waste, resulting in low energy efficiency and poor overall device lifespan. Summary of the Invention

[0004] The main technical problem solved by this invention is to provide a heating non-combustible device and its heating method, which aims to improve the heating uniformity, energy utilization rate and endurance of the heating non-combustible device.

[0005] According to a first aspect, one embodiment provides a heating non-combustible device, comprising:

[0006] The shell has a containment cavity for accommodating aerosol generators;

[0007] Multiple heating elements are provided, and the multiple heating elements are evenly arranged on the cavity wall of the receiving cavity for inserting aerosol generators;

[0008] A control component is mounted on the housing and is independently electrically connected to each of the heating elements. The control component is configured to independently control the heating of each of the heating elements.

[0009] In one alternative embodiment, the receiving cavity extends in a first direction, and the plurality of heating elements are arranged in the first direction; the control component is configured to sequentially control each of the heating elements to heat independently in the first direction.

[0010] In one alternative embodiment, the heating element includes a plurality of heating teeth for inserting into the aerosol generator, the heating teeth having an end and teeth, the end being fixed to the cavity wall of the receiving cavity and electrically connected to the control component, and the teeth protruding from the end for inserting into the aerosol generator.

[0011] In one alternative embodiment, a plurality of the heating teeth are spaced apart in a second direction, which is perpendicular to the first direction.

[0012] In one alternative embodiment, two adjacent heating teeth in the same heating element are staggered in the second direction.

[0013] In one optional embodiment, the cavity wall of the receiving cavity is provided with mounting seats corresponding to the heating teeth one by one, and the heating teeth are electrically connected to the control component through the corresponding mounting seats;

[0014] The mounting base includes a first mounting base and a second mounting base arranged at intervals, and the end includes a first connecting end and a second connecting end, wherein the first connecting end is connected to the first mounting base and the second connecting end is connected to the second mounting base.

[0015] In one optional embodiment, the housing includes an upper cover and a lower cover, the upper cover being provided with a first receiving groove and the lower cover being provided with a second receiving groove, the first receiving groove and the second receiving groove being assembled together to form the receiving cavity;

[0016] The housing includes a first magnetic element disposed on the upper cover and a second magnetic element disposed on the lower cover. The first magnetic element and the second magnetic element attract each other to lock the upper cover and the lower cover together.

[0017] In one optional embodiment, both the upper cover and the lower cover are provided with the heating element;

[0018] The control component includes a first control unit mounted on the upper cover and a second control unit mounted on the lower cover, wherein the first control unit and the second control unit are electrically connected through a conductive connection structure;

[0019] The conductive connection structure includes a conductive hole and a conductive post that mates with the conductive hole. The conductive hole is disposed in one of the upper cover and the lower cover, and the conductive post is disposed in the other of the upper cover and the lower cover.

[0020] According to a second aspect, one embodiment provides a heating method for a non-combustible heating device, comprising:

[0021] Obtain the current cumulative heating time and total suction time of the heating non-combustible device;

[0022] The current cumulative heating time and the total suction time are analyzed and calculated to determine the calculation results;

[0023] Based on the calculation results, determine the conditions and parameters of the target heating element that needs to participate in the heating process;

[0024] The target heating element is heated separately.

[0025] In an optional embodiment, determining the conditions and parameters of the target heating element to be heated based on the calculation results includes:

[0026] If the ratio of the current cumulative heating time to the total suction time is less than or equal to 1 / N, then among the N heating elements arranged sequentially in the first direction, the first heating element is the target heating element participating in the heating.

[0027] If the ratio of the current cumulative heating time to the total suction time is greater than (n-1) / N and 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 participating in the heating.

[0028] If the ratio of the current cumulative heating time to the total suction time is greater than n / N and less than (n+1) / N, then the (n+1)th heating element among the N heating elements arranged sequentially in the first direction is determined to be the target heating element participating in the heating.

[0029] If the ratio of the current cumulative heating time to the total suction time is equal to 1, the number of target heating elements participating in the heating is determined to be zero;

[0030] Wherein the first direction is the length direction of the aerosol generated, N is the total number of heating elements, and n is a positive integer less than N.

[0031] According to the above-described embodiments of the heated non-combustible device and its heating method, the heated non-combustible device includes a housing, heating elements, and a control assembly. The housing has a receiving cavity for accommodating aerosol generators. Multiple heating elements are provided, and the multiple heating elements are evenly disposed on the cavity wall of the receiving cavity for inserting aerosol generators. The control assembly is mounted on the housing and is independently electrically connected to each heating element. The control assembly is configured to independently control the heating of each heating element. Because the heating element can penetrate the aerosol generator, the contact area between the heating element and the aerosol generator is increased, which helps to improve the heating uniformity of the aerosol generator, reduce the temperature differences of the aerosol generator in different areas, and reduce the occurrence of burnt taste and waste of aerosol generator in the later stage of heating. Furthermore, the control component can independently control the heating of each heating element. This allows for the sequential and individual control of one or more heating elements based on the analysis and calculation results of the cumulative heating time and the total suction time. This reduces the heating time of individual heating elements and the heating time of the corresponding aerosol generator, which helps to avoid overheating of some aerosol generators, avoid energy waste, and improve the energy utilization rate and endurance of the entire device.

[0043] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0044] Furthermore, 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 be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0045] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0046] This application discloses a heated non-combustible device 100, which includes a housing 10, a heating element 50, and a control assembly 30. The housing 10 has a receiving cavity 101 for accommodating aerosol products (e.g., cigarette sticks, tobacco shreds, etc.). The heating element 50 is mounted on the housing 10 and protrudes from the cavity wall of the receiving cavity 101 to penetrate the aerosol products. Multiple heating elements 50 are provided and are evenly arranged on the cavity wall of the receiving cavity 101. The control assembly 30 is mounted on the housing 10 and is independently electrically connected to each heating element 50. The control assembly 30 is configured to independently control the heating of each heating element 50.

[0047] Since the heating element 50 can penetrate the aerosol generator, the contact area between the heating element 50 and the aerosol generator can be increased, which helps to improve the heating uniformity of the aerosol generator, reduce the temperature difference of the aerosol generator in different places, and reduce the occurrence of burnt taste and waste of aerosol generator in the later stage of heating.

[0048] Furthermore, the heating-non-combustible device 100 can independently control the heating of each heating element 50. For example, based on the analysis and calculation results of the cumulative heating time and the total suction time, it can sequentially and individually control the heating of one or more heating elements 50. The cumulative heating time is the total heating time of the heating elements 50 during a single suction process; the total suction time is the total heating time, based on the volume of the receiving cavity 101, ensuring that all aerosol products filled in the receiving cavity 101 are sufficiently heated without the generation of toxic substances. In other words, the total suction time is determined based on the volume of the receiving cavity 101. For example, the control component 30 can progressively increase the ratio of the cumulative heating time to the total suction time, sequentially controlling one or two heating elements 50 to heat independently until the ratio reaches 1, thus completing the heating of all heating elements 50 and all aerosol products. This reduces 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 of some aerosol products, preventing energy waste, and helping to improve the energy utilization rate and endurance of the entire device.

[0049] Specifically, in some embodiments, the receiving cavity 101 can be a receiving hole extending in a first direction, and the heating elements 50 are arranged continuously or intermittently in the first direction, which is the length direction of the heated non-combustible device 100. The control component 30 can control each heating element 50 to heat independently in the first direction according to the ratio of the cumulative heating time to the total smoking time; for example, as the ratio increases step by step, one heating element 50 can be controlled to heat independently in the first direction at a time until the ratio is 1, completing the heating of all heating elements 50 and all aerosol products. This can simulate the actual smoking process, ensuring that the aerosol products corresponding to each heating element 50 are fully heated and avoiding overheating, further improving energy utilization and enhancing the user experience.

[0050] In one embodiment, the heating element 50 includes a plurality of heating teeth 501 spaced apart in a second direction, which is the width direction of the heating non-combustible device 100 perpendicular to the first direction. Each heating tooth 501 extends in the first direction. Two adjacent heating teeth 501 are staggered in the second direction, which helps to make the heating teeth 501 uniformly arranged on the cavity wall surface of the receiving cavity 101, and helps to improve the heating uniformity of the entire heating non-combustible device 100.

[0051] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 Three heating teeth 501 can be provided. The three heating teeth 501 are arranged at intervals in the second direction. The heating tooth 501 located in the middle position is staggered from the heating tooth 501 located at the end in the second direction.

[0052] Optionally, the number of heating elements 50 is not limited to three, but can be two, four or more. For a large number of heating teeth 501, multiple heating teeth 501 can be arranged in rows and columns in the first direction and the second direction respectively to achieve uniform arrangement on the side wall of the receiving cavity 101.

[0053] In addition, the heating teeth 501 in the heating element 50 can also be aligned in the second direction, as long as two adjacent heating elements 50 are continuous in the first direction or are close together; or in some other embodiments, the heating element 50 may also include heating wires uniformly laid on the cavity wall surface of the receiving cavity 101, the heating wires having an inserting portion for inserting into the aerosol generator.

[0054] In some embodiments, please continue to refer to Figure 2 , Figure 3 , Figure 5 and Figure 6The heating tooth 501 has an elongated structure, and its length direction is in the same direction as the first direction. The heating tooth 501 has an end portion 502 and a tooth portion 503. The end portion 502 of the heating tooth 501 is fixed to the cavity wall of the receiving cavity 101 and electrically connected to the control component 30. The tooth portion 503 of the heating tooth 501 protrudes from the end portion 502 for piercing into the aerosol generator. The end portion 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. The tooth portion 503 of the heating tooth 501 is fixedly connected between the first connecting end 5021 and the second connecting end 5022 and protrudes towards the center of the receiving cavity 101 to form an insertion tip for piercing the aerosol generator. The insertion tip helps to increase the depth of the heating tooth 501 into the aerosol product, thereby increasing the contact area between the heating tooth 501 and the aerosol product and improving the heating uniformity of the heating tooth 501 on the aerosol product.

[0055] In other embodiments, in order to increase the contact area between the heating tooth 501 and the aerosol generator, a plurality of branch structures can be provided between the first connecting end 5021 and the second connecting end 5022. The plurality of branch structures protrude toward the center of the receiving cavity 101 to form short teeth for embedding in the aerosol generator.

[0056] In some embodiments, please refer to Figure 2 and Figure 5 The cavity wall of the receiving cavity 101 is provided with mounting seats 6 corresponding to the heating teeth 501. The receiving cavity 101 is formed by assembling and mating a first receiving groove 11 and a second receiving groove 21 in the third direction. The third direction, the second direction, and the first direction are perpendicular to each other. The end face of the mounting seat 6 facing the cavity 101 in the third direction is not higher or lower than the cavity wall surface of the receiving cavity 101. The heating teeth 501 are electrically connected to the control component 30 provided in the housing 10 through the corresponding mounting seat 6. The heating teeth 501 can be made of materials such as nickel-chromium alloy, iron-chromium alloy, and stainless steel. The mounting seats 6 can be made of low-resistance materials such as copper alloy, silver-palladium alloy, and pure gold.

[0057] Mounting base 6 includes a first mounting base 61 and a second mounting base 62 arranged at intervals in a first direction. The first mounting base 61 is a low-pressure mounting base, and the second mounting base 62 is a high-pressure mounting base. The first connecting end 5021 of the heating tooth 501 is fixedly connected to the first mounting base 61, and the second connecting end 5022 is fixedly connected to the second mounting base 62. The two ends of the heating tooth 501 are respectively connected to the high-pressure mounting base and the low-pressure mounting base to form a resistor for heating aerosol products. By controlling the power supply of the heating tooth 501, the heating temperature of the heating tooth 501 can be controlled to ensure that the aerosol products have a suitable heating temperature.

[0058] Optionally, in some other embodiments, the heating element 50 may further include a plurality of heating rods, which are spaced apart in a second direction. One end of the heating rod is a connecting end and the other end is a heating end. The heating rod passes through the cavity wall of the receiving cavity 101. The connecting end of the heating rod is located inside the housing 10 and is electrically connected to the control component 30. The heating end protrudes through the cavity wall of the receiving cavity 101 toward the receiving cavity 101 to be embedded in the aerosol generator.

[0059] In some embodiments, the heating element 50 includes a first heating element 51 and a second heating element 52 arranged in pairs. The first heating element 51 and the second heating element 52 are staggered in a first direction. That is, in a structure with more than three heating elements 50, 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.

[0060] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 For the first heating element 51, the first connecting ends 5021 of the multiple heating teeth 501 are located on the side of the second connecting end 5022 facing the second heating element 52 in the first direction. This facilitates the connection between the first connecting ends 5021 of the heating teeth 501 in the first heating element 51 and the first connecting ends 5021 of the heating teeth 501 in the second heating element 52, thereby reducing the number of first mounting seats 61 provided on the housing 10. In addition, it also facilitates the electrical connection between the first mounting seat 61 corresponding to the first heating element 51 and the first mounting seat 61 corresponding to the second heating element 52 on the housing 10, thereby reducing the number of wires connecting the first mounting seat 61 to the control component 30.

[0061] Correspondingly, the first connecting ends 5021 of the multiple heating teeth 501 in the second heating element 52 can also be located in the first direction on the side of the second connecting end 5022 facing the first heating element 51. This facilitates the connection of multiple first connecting ends 5021 to the same first mounting base 61, or the electrical connection of multiple first mounting bases 61. It also helps to reduce the number of first mounting bases 61 provided on the housing 10 or the number of wires connecting the first mounting base 61 to the control component 30.

[0062] Of course, in other embodiments, two adjacent first heating elements 51 can be arranged to form a first heating group, and two adjacent second heating elements 52 can be arranged to form a second heating group. The first heating group and the second heating group are staggered in the first direction, that is, two first heating elements 51 and two second heating elements 52 are staggered in the first direction. In such a structure, in the adjacent first heating elements 51 and second heating elements 52, the first connecting end 5021 of some heating teeth 501 in the first heating element 51 can be located on the side of the second connecting end 5022 away from the second heating element 52 in the first direction; or the first connecting end 5021 of some heating teeth 501 in the second heating element 52 can be located on the side of the second connecting end 5022 away from the first heating element 51 in the first direction. In this way, two adjacent first heating elements 51 or two adjacent second heating elements 52 have first connecting ends 5021 close to each other, so as to facilitate the connection of multiple first connecting ends 5021 in the first heating element 51 to the same first mounting base 61, or to facilitate the electrical connection of multiple first mounting bases 61 corresponding to the first heating element 51.

[0063] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 The first heating element 51 has three heating teeth 501. The heating tooth 501 located in the middle position in the second direction is positioned closer to or further away from the second heating element 52 in the first direction, so that adjacent heating teeth 501 in the first heating element 51 are staggered in the second direction. Correspondingly, the second heating element 52 also has three heating teeth 501. The heating tooth 501 located in the middle position in the second direction is positioned closer to or further away from the first heating element 51 in the first direction, so that adjacent heating teeth 501 in the second heating element 52 are staggered in the second direction.

[0064] Furthermore, the first connecting ends 5021 of at least two adjacent heating teeth 501 in the first direction are connected and connected to the same first mounting base 61; the two adjacent heating teeth 501 can be the heating tooth 501 located in the middle position in the second direction of the first heating element 51 and the heating tooth 501 located in the middle position in the second direction of the second heating element 52, respectively. Please refer to [reference needed]. Figure 5 and Figure 6 As shown; two adjacent heating teeth 501 can also be the heating teeth 501 located at the ends in the second direction of the first heating element 51 and the heating teeth 501 located at the ends in the second direction of the second heating element 52, please refer to Figure 3 As shown. This arrangement helps reduce the number of mounting bases 6 on the cavity wall of the receiving cavity 101, and also reduces the number of connecting wires between the mounting bases 6 and the control assembly 30.

[0065] In some embodiments, the first connecting ends 5021 of multiple heating teeth 501 in the same heating element 50, that is, multiple heating teeth 501 in the second direction, are located on the same side of the second connecting end 5022. The first mounting base 61 corresponding to these heating teeth 501 is also located on the same side of the second mounting base 62. This facilitates electrical connection with multiple first mounting bases 61 corresponding to the same heating element 50, so as to reduce the length and number of connecting wires between the first mounting base 61 and the control component 30 without affecting the independent heating of each heating element 50.

[0066] In the embodiment where the first connection ends 5021 of the two adjacent heating teeth 501 belonging to the two heating elements 50 respectively are close to each other, they are electrically connected to the multiple first mounting seats 61 corresponding to the two adjacent heating elements 50 respectively. This can also reduce the length and number of connecting wires between the first mounting seat 61 and the control component 30 without affecting the independent heating of each heating element 50.

[0067] Please refer to Figure 4 and Figure 7 ,in Figure 4 In the adjacent first heating element 51 and second heating element 52, the four first mounting bases 61 connected to the first connection end 5021 of the six heating teeth 501 are connected by short wires and then connected to the control component 30 by the same connecting wire. Figure 7 In the middle, among the adjacent first heating element 51 and second heating element 52, among the five first mounting bases 61 connected to the first connection end 5021 of the six heating teeth 501, two of the first mounting bases 61 are connected by a jumper wire and then connected to the control component 30 by a connecting wire, and the other three first mounting bases 61 are also connected by a jumper wire and then connected to the control component 30 by the same connecting wire.

[0068] For embodiments where the first connecting ends 5021 and second connecting ends 5022 of each heating tooth 501 in the same heating element 50 are arranged in the same direction, please refer to... Figure 4 and Figure 7 Each heating tooth 501 can also be electrically connected to its corresponding second mounting base 62 via one or two wires, thereby reducing the length and number of connecting wires between the mounting base 6 and the control component 30 without affecting the independent control of each heating element 50.

[0069] Of course, the structure in which multiple first mounting bases 61 are connected to the control component 30 via a single wire can also be applied to the same heating element 50, i.e., in embodiments where the relative positions of the first connecting ends 5021 and the second connecting ends 5022 of two adjacent heating teeth 501 in the second direction are inconsistent; it can also be applied to embodiments in which they belong to different heating elements 50, i.e., in embodiments where the first connecting end 5021 of one heating tooth 501 is located away from the other heating tooth 501 from the second connecting end 5022. Similarly, the structure in which multiple second mounting bases 62 are connected to the control component 30 via one or two wires can also be applied to embodiments in the same heating element 50 where the arrangement directions of the first connecting ends 5021 and the second connecting ends 5022 of different heating teeth 501 are inconsistent.

[0070] Of course, in order to avoid poor contact between the mounting base 6 and one of the wires in the control component 30, which would affect the operation of multiple heating teeth 501, high-voltage connection wires and low-voltage connection wires can be configured for each mounting base 6 of each heating tooth 501 to ensure that each heating tooth 501 is relatively independent.

[0071] In some embodiments, please refer to Figure 2 The heated non-combustible device 100 includes an upper cover 1 and a lower cover 2, which are rotatably connected by pivots at their respective ends, for example, by hinges. The end of the upper cover 1 away from the pivot is provided with a first receiving groove 11, and the end of the lower cover 2 away from the pivot is provided with a second receiving groove 21. The first receiving groove 11 and the second receiving groove 21 can be assembled and joined together during the rotation of the upper cover 1 and the lower cover 2 to form a receiving cavity 101 for placing aerosol generators. Heating elements 50 are provided on the walls of both the first receiving groove 11 and the second receiving groove 21.

[0072] A locking structure is provided on the housing 10 between the upper cover 1 and the lower cover 2. Specifically, the locking structure includes a first magnetic element 13 provided on the upper cover 1 and a second magnetic element 23 provided on the lower cover 2. After the upper cover 1 and the lower cover 2 are assembled together, the first magnetic element 13 and the second magnetic element 23 attract each other to lock the upper cover 1 and the lower cover 2, preventing the upper cover 1 and the lower cover 2 from automatically loosening and causing aerosols to fall out of the receiving cavity 101.

[0073] Of course, in some other embodiments, the upper cover 1 and the lower cover 2 can be fixedly connected, so that the aerosol generator enters the receiving cavity 101 from the opening of the receiving cavity 101 at the end of the length direction of the housing 10, and the heating teeth 501 are inserted into the aerosol generator.

[0074] In some embodiments, both the upper cover 1 and the lower cover 2 are hollow shell structures. The upper cover 1 has a first mounting cavity 14 inside, and the lower cover 2 has a second mounting cavity 25 inside. The opening of the first receiving groove 11 on the upper cover 1 is disposed away from the first mounting cavity 14, and the opening of the second receiving groove 21 on the lower cover 2 is disposed away from the second mounting cavity 25. The control component 30 includes a first control unit 31 installed in the first mounting cavity 14 and a second control unit 32 installed in the second mounting cavity 25. Each control unit includes an electrically connected PCB bridge board 301 and an IC module. Multiple mounting seats 6 disposed on the cavity wall of the receiving cavity 101 are connected to the corresponding PCB bridge board 301 through connecting wires. The IC module is used to control the independent heating of each heating element 50 in the corresponding upper cover 1 or lower cover 2.

[0075] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 The first control unit 31 and the second control unit 32 are electrically connected through a conductive connection structure, which includes a conductive post 12 disposed on the upper cover 1 and a conductive groove 22 disposed on the lower cover 2. The conductive post 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 assembled and aligned, the conductive post 12 and the conductive groove 22 are inserted and fitted together to realize the electrical connection between the first control unit 31 and the second control unit 32.

[0076] Furthermore, a power module 5 is also provided in the second mounting cavity 25 of the lower cover 2. The power module 5 is electrically connected to the second control unit 32 in the lower cover 2. The power module 5 includes a charging connector 24 disposed at the end of the lower cover 2 in the length direction of the housing 10. The charging connector 24 is used to connect an external power source to charge the heating non-combustible device 100.

[0077] In some embodiments, please refer to Figure 1 In the heated non-combustible device 100, the outer contour of the upper cover 1 is generally a cuboid, and rounded corners can be provided at the corresponding edges and corners of the cuboid on the upper cover 1. The outer contour of the lower cover 2 is also generally a cuboid, and rounded corners can also be provided at the corresponding edges and corners of the cuboid on the lower cover 2. This can prevent sharp parts on the outer contours of the upper cover 1 and the lower cover 2 from scratching the user. After the upper cover 1 and the lower cover 2 are assembled together, they form a shell 10. The cross-sectional shape of the shell 10 along its length is generally rectangular, and rounded corners can be provided at the corresponding rectangular edges and corners of the cross-section.

[0078] The opening of the receiving hole, which is formed by the assembly of the first receiving groove 11 and the second receiving groove 21, is located at the end of the housing 10 along its length. A suction nozzle 4 is also provided at one end of the housing 10 along its length. The suction nozzle 4 has a first end opening and a second end opening 41 at both ends of the housing 10 along its length. The first end opening and the second end opening 41 are connected. The suction nozzle 4 is nested at the end of the housing 10 through the first end opening, and the first end opening of the suction nozzle 4 is connected to the opening of the receiving hole. In this way, the aerosol generated in the receiving hole can be inhaled by the user by passing through the opening of the receiving hole, the first end opening, and the second end opening 41 in sequence. The outer contour of the cross-section of the end with the first opening on the nozzle 4 is generally rectangular. The edges and corners of the nozzle 4 are rounded. The shape of the first opening can also be rectangular. The shape of the first opening matches the outer contour of the end of the housing 10. The nozzle 4 is made of silicone material. The first opening of the nozzle 4 fits over the outside of the housing 10 to achieve a fixed connection with the housing 10. The shape of the second opening 41 is circular. The overall cross-sectional size of the second end is smaller than that of the first end to facilitate the user to hold the second opening 41 in their mouth.

[0079] In one embodiment, during use, the heating teeth 501 of the heated non-combustible device 100 penetrate the aerosol generator. Based on the current cumulative heating time and total heating time of the heated non-combustible device 100, one or more heating elements 50 at different positions along the length of the housing 10 are sequentially heated under suitable temperature conditions, so that all heating elements 50 complete one heating cycle when the cumulative heating time equals the total suction time. This ensures that every part of the aerosol generator arranged along the length of the housing 101 is fully and uniformly heated, without a burnt taste or toxic substances, and also avoids overheating of a single heating element 50. On the other hand, it helps to avoid energy waste, effectively improves energy utilization, and enhances the overall endurance of the heated non-combustible device 100.

[0080] This application also discloses a heating method for the heating non-combustible device 100 in any of the above embodiments. Please refer to [link / reference needed]. Figure 8 The heating method includes:

[0081] S1: Obtain the current cumulative heating time and total suction time of the heating non-combustible device;

[0082] S2: Analyze and calculate the current cumulative heating time and total suction time, and determine the calculation results;

[0083] S3: Based on the calculation results, determine the conditions and parameters of the target heating element that needs to be heated;

[0084] S4: Control the heating of the target heating element separately.

[0085] In some embodiments, in step S1 above, the cumulative heating time is the cumulative heating time of the heating element 50 during one suction process, and the total suction time can be the total heating time based on the volume of the receiving cavity 101 to ensure that all aerosol products filled in the receiving cavity 101 can be fully heated and no toxic substances are generated. The cumulative heating time and the total suction time are obtained by the control component 30 of the heated non-combustible device 100.

[0086] In step S2 above, the control component 30 analyzes and calculates the current cumulative heating time and the total suction time to obtain the calculation result. The analysis and calculation here can be to calculate the ratio of the current cumulative heating time to the total suction time, or it can simply be to determine whether the current cumulative heating time is greater than the set cumulative heating time. The set cumulative heating time is less than the total suction time, and the set cumulative heating time is determined by the user according to the usage situation. For example, the set cumulative heating time can be half, one-third or two-thirds of the total suction time.

[0087] In step S3 above, the control component 30 still determines the conditions and parameters of the target heating element to be heated based on the calculation results in step S2. The conditions can be the positional conditions of the target heating element, such as being the first, adjacent first and second, or multiple elements arranged sequentially along the length of the receiving cavity 101, or multiple elements arranged at intervals. If multiple heating elements 50 are arranged in the second direction, the positional conditions of the target heating element can also be the first, first and second, or multiple elements arranged at intervals in the second direction. The parameters of the target heating element can be the number of target heating elements or the heating power. The number of target heating elements can be one or more, and the heating power can be the total power of multiple heating elements 50 heated simultaneously, or the power of a single heating element 50.

[0088] The location, quantity, and power of the target heating element to be heated can be determined based on the ratio of the current cumulative heating time to the total suction time; alternatively, the location, quantity, and power can be determined based on whether the current cumulative heating time is greater than the set cumulative heating time. The power can be determined independently based on the cumulative heating time; for example, the power can gradually increase as the cumulative heating time increases, or it can first gradually increase and then gradually decrease as the cumulative heating time increases.

[0089] Finally, in S4, the target heating element determined in S3 is controlled by the control component 30 to participate in heating.

[0090] This method of controlling the heating of different positions and numbers of heating elements 50 sequentially or in sequence based on the cumulative heating time and the total suction time helps to reduce the heating time of a single heating element 50 and the heating time of some aerosol products corresponding to each heating element 50. It helps to avoid overheating of some aerosol products, avoid energy waste, improve heating efficiency and energy utilization, and improve the endurance of the heating non-combustion device 100.

[0091] In some embodiments, please refer to Figure 9 Step S3: Based on the calculation results, determine the conditions and parameters of the target heating element that needs to be heated, including:

[0092] S31: If the ratio of the current cumulative heating time to the total suction time is less than or equal to 1 / N, determine that among the N heating elements arranged sequentially in the first direction, the first heating element is the target heating element participating in the heating.

[0093] S32: If the ratio of the current cumulative heating time to the total suction time is greater than (n-1) / N and less than or equal to n / N, determine that among the N heating elements arranged sequentially in the first direction, the nth heating element is the target heating element participating in the heating.

[0094] S33: If the ratio of the current cumulative heating time to the total suction time is greater than n / N and less than (n+1) / N, determine that among the N heating elements arranged in sequence in the first direction, the (n+1)th heating element is the target heating element participating in the heating;

[0095] S34: If the ratio of the current cumulative heating time to the total suction time is equal to 1, the number of target heating elements participating in the heating is determined to be zero;

[0096] Wherein, the first direction is the length direction of the aerosol generated, N is the total number of heating elements 50, and n is a positive integer less than N.

[0097] 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 position conditions and quantity parameters of the target heating element, respectively.

[0098] In one example, the total number N of heating elements 50 is set to 2, meaning that a first heating element 51 and a second heating element 52 are arranged along the length of the aerosol generated. The number and length of heating teeth 501 in each heating element 50 are equal. The ratio of the cumulative heating time to the total suction time is determined as follows: if the cumulative heating time is less than or equal to half of the total suction time, the first heating element 51, which is farther away from the nozzle 4 in the first direction, is identified as the target heating element. Then, the first heating element 51 is controlled to heat, while the second heating element 52 remains unheated. If the cumulative heating time is greater than half of the total suction time but less than 1, the second heating element 52, which is closer to the nozzle 4 in the first direction, is identified as the target heating element. Then, the second heating element 52 is controlled to heat, while the first heating element 51 is kept unheated or adjusted to not heat. If the cumulative heating time is equal to the total suction time, meaning that all aerosol generated is fully heated and all heating elements 50 have completed one heating cycle, all heating elements 50 are stopped heating.

[0099] Of course, in other embodiments, the total number N of heating elements 50 can be 3 or more. If the number of heating elements 50 is set to three, two first heating elements 51 and a second heating element 52 located between the two first heating elements 51 can be set, and the number and length of heating teeth 501 in each heating element 50 are equal. If the cumulative heating time is less than or equal to one-third of the total heating time, only one of the first heating elements 51 is determined as the target heating element to start heating; if the cumulative heating time is greater than one-third of the total heating time but less than or equal to two-thirds of the total heating time, only the second heating element 52 is determined as the target heating element to start heating; if the cumulative heating time is greater than two-thirds of the total heating time but less than the total heating time, only the other first heating element 51 is determined as the target heating element to start heating; if the cumulative heating time is equal to the total suction time, that is, all aerosol products are fully heated, all heating elements 50 have completed one heating, and all heating elements 50 stop heating.

[0100] This simulates the actual smoking process, allowing each part of the aerosol generated in the first direction to be heated independently, with each part heated for an equal duration. This avoids overheating of local aerosols, which could produce toxic substances, or prevents some aerosols from being underheated and unable to generate aerosols. This improves the smoking experience, increases heating efficiency and energy utilization, and enhances the overall battery life of the heated non-combustible device 100.

[0101] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
