Description

Technical Field

[0001] This invention relates to the field of electronic atomization technology, and in particular to a heating non-combustible device and its heating method. Background Technology

[0002] A heated non-combustible device, also known as a low-temperature non-combustible heating device, is an electronic device that heats herbal products at low temperatures (generally 200–400°C) to form a suction-capable aerosol. In related technologies, the herbal product is mainly composed of a filter nozzle and herbal material connected to the filter nozzle, and the whole is cylindrical. When in use, the herbal product is directly inserted into the heating chamber of the heated non-combustible device, with the filter nozzle exposed. Then, the heater of the heated non-combustible device is turned on for preheating. When the preheating temperature is reached, the main unit indicates that it can be used, and the user can then begin suction.

[0003] However, in existing heat-not-burn devices, the heating chamber is in an open state during the preheating process of herbal products. That is, both the air inlet and outlet channels of the heat-not-burn device are open. When the temperature rises, hot air will diffuse outward along the air inlet and outlet channels, resulting in heat loss and prolonging the preheating time. Summary of the Invention

[0004] The main objective of this invention is to provide a heating non-combustible device and its heating method, aiming to solve the technical problem of long preheating time in heating non-combustible devices.

One end of the first cover portion is connected to one end of the second cover portion, and there is a gap between the end face of the first cover portion and the end face of the second cover portion. A plurality of air inlet holes are provided on the end face of the second cover portion corresponding to the gap, which are arranged circumferentially around the second cover portion. The sealing cover is disposed inside the second cover portion, and the second cover portion is movably connected to one end of the outer shell.

[0023] Furthermore, the outer cover is hinged to one end of the outer shell, and a first locking member is provided on the outer side wall of the one end of the outer shell.

In the axial cross-section of the conductive ceramic body, the end where the positive electrode wire is connected to the conductive ceramic body is diagonally opposite to the end where the negative electrode wire is connected to the conductive ceramic body.

[0031] To achieve the above objectives, the present invention also provides a heating method for the aforementioned heating non-combustible device, comprising the following steps:

[0032] Receive a start command and control the drive device to move the heating chamber to the first predetermined position according to the start command, so that the sealing cover closes the cylinder;

[0033] The heating chamber is controlled to heat the substance to be heated in the cylinder to a predetermined temperature, wherein the predetermined temperature is the atomization temperature or atomization critical temperature of the substance to be heated, the atomization critical temperature is lower than the atomization temperature, and the atomization temperature refers to the temperature at which the substance to be heated can generate an aerosol without combustion.

[0037] Furthermore, after issuing a prompt to the user, the heating method further includes:

[0038] The device receives a heating command and controls the heating chamber to heat the material to be heated inside the cylinder to the atomization temperature according to the heating command.

[0039] Compared with the prior art, the beneficial effects of the present invention are:

[0040] The heated non-combustible device provided in this application includes a housing, a heating chamber, a sealing assembly, and a driving device. The housing has an opening at one end along its length. The heating chamber has a cylindrical body that can contain the substance to be heated and atomize it. The heating chamber is movably connected to one end of the housing, and the cylindrical body is connected to the opening. The sealing assembly is also movably connected to one end of the housing and is used to open and close the opening. The sealing assembly includes a sealing cap and an outer cap. An airflow channel is formed between the top outer periphery of the sealing cap and the bottom of the outer cap and they are adapted to each other. The top of the outer cap has a receiving cavity for placing a filter nozzle. A pressure relief valve is formed between the bottom outer edge of the sealing cap and the top outer edge of the heating chamber. The pressure relief valve is used to open or close the flow path between the airflow channel and the heating chamber. The driving device is installed in the housing and connected to the heating chamber. After being powered on, it can drive the heating chamber to move between a first predetermined position and a second predetermined position along the length of the housing, thereby opening or closing the flow path between the airflow channel and the heating chamber.

[0041] As can be seen from the above, the heat-not-burning device provided in this application embodiment is suitable for herbal products where the filter tip and the substance to be heated are separated. When heating the substance, the heating chamber containing the substance is sealed and closed by a sealing cap. The driving device moves the heating chamber from a second predetermined position to a first predetermined position, and the pressure relief valve is closed. At this time, the substance is in a heating environment isolated from the outside air. As heating progresses, the pressure inside the chamber increases with the temperature, allowing the substance to be heated to be in a closed and high-pressure (greater than one atmosphere) heating environment. In this closed heating environment, the hot air inside the chamber is less likely to diffuse outwards, and the temperature rises more easily in the high-pressure environment, thus quickly heating the substance to the predetermined temperature. When the substance reaches the predetermined temperature, the driving device immediately moves the heating chamber back from the first predetermined position to the second predetermined position, and the pressure relief valve opens. The chamber then reconnects with the airflow channel through the pressure relief valve, allowing the user to bite the filter tip and perform a suction action. This structural design provides a sealed, high-pressure heating environment for the substance to be heated during the heating and atomization process, thereby quickly heating the substance to the required temperature. This effectively shortens the waiting time for users to inhale the "first puff" of aerosol and improves the user experience. Attached Figure Description

[0080] Reference Figures 1 to 10 This invention provides a heat-not-burning device, which includes a housing 1, a sealing assembly 3, a driving device 4, and a heating chamber 2 for heating a substance 101 to be heated, wherein:

[0081] The outer shell 1 has an opening 11 at one end along its length;

[0082] The heating chamber 2 has a cylindrical body 22 that can accommodate the substance 101 to be heated. The heating chamber 2 is movably installed inside one end of the outer shell 1, and the cylindrical body 22 is connected to the opening 11 of the outer shell 1. Specifically, the cylindrical body 22 has a cavity 220 that can accommodate the substance 101 to be heated, and the cavity 220 inside the cylindrical body 22 is connected to the opening 11 of the outer shell 1.

[0083] The sealing assembly 3 is movably connected to one end of the outer shell 1 and can open or close the opening 11 of the outer shell 1. The sealing assembly 3 includes a sealing cover 31 and an outer cover 32. An airflow channel 33 is formed between the top outer periphery of the sealing cover 31 and the bottom of the outer cover 32. The sealing cover 31 is adapted to be connected inside the outer cover 32. The top of the outer cover 32 has a receiving cavity 3211 that can accommodate the filter nozzle 102. A pressure relief valve 105 is formed between the bottom outer edge of the sealing cover 31 and the top outer edge of the heating chamber 2. The pressure relief valve 105 is used to open or close the flow path between the airflow channel 33 and the heating chamber 2.

[0084] The drive device 4 is installed inside the outer shell 1 and connected to the heating chamber 2. The drive device 4 is used to drive the heating chamber 2 to move between the first predetermined position 103 and the second predetermined position 104 along the length direction of the outer shell 1, so that the pressure relief valve 105 opens or closes.

[0085] In this embodiment, during specific implementation, the capping assembly 3 can be movably connected to one end of the outer shell 1 through hinges, threaded connections, or other means.

[0086] The heat-not-burning device provided in this embodiment is suitable for herbal products where the filter 102 and the substance to be heated 101 are separated. Its operating principle is as follows:

[0087] First, please refer to Figure 3-5 The sealing assembly 3 and the heating chamber 2 are in an open or semi-open state, that is, the opening 11 of the outer shell 1 is in a fully open or semi-open state. Before starting the heating non-combustible device for heating, the filter nozzle 102 can be inserted into the receiving cavity 3211 of the outer cover 32 (refer to...). Figure 2 and Figure 3 The substance to be heated 101 is placed in the cylinder 22 of the heating chamber 2. Alternatively, the filter 102 can be inserted into the receiving cavity 3211 of the outer cover 32 after the outer cover 32 is closed. Figure 5 It can be seen that the cylinder 22 containing the material to be heated 101 is open at this time, that is, the opening 11 is in a fully open or semi-open state.

[0088] In this embodiment, when the sealing assembly 3 closes the opening 11 of the outer shell 1 and the driving device 4 drives the heating chamber 2 to move to the first predetermined position 103, the pressure relief valve 105 closes, and the flow path between the airflow channel 33 and the heating chamber 2 is closed. That is, at this time, the bottom of the sealing cover 31 is tightly connected to the top of the heating chamber 2 to achieve the sealing of the cylinder 22. When the sealing assembly 3 closes the opening 11 of the outer shell 1 and the driving device 4 drives the heating chamber 2 to move to the second predetermined position 104, the pressure relief valve 105 opens, and the flow path between the airflow channel 33 and the heating chamber 2 is connected. That is, at this time, the top of the heating chamber 2 is disengaged from the bottom of the sealing cover 31, so that the cylinder 22 is connected to the airflow channel 33.

[0089] Next, please refer to Figure 6 You can also refer to Figure 9 and Figure 10 The sealing assembly 3 is then closed, so that the sealing cap 31 in the sealing assembly covers the cylinder 22 of the heating chamber 2. At this time, the bottom of the sealing cap 31 is in contact with the upper surface of the substance 101 to be heated placed in the cylinder 22 of the heating chamber 2. Of course, the bottom of the sealing cap 31 may not be in direct contact with the substance 101 to be heated, depending on the amount of substance 101 to be heated. At this time, a space is formed between the top outer periphery of the sealing cap 31 and the bottom of the outer cover 32, and this space is the airflow channel 33. At this time, the upper end of the heating chamber 2 is located in the initial second predetermined position 104 in the axial direction of the heating non-combustible device.

[0090] Next, please refer to Figure 7 and Figure 8 When the heat-not-burning device is activated for heating, the device first controls the drive unit 4 to move the heating chamber 2 from the initial second predetermined position 104 toward the direction closer to the sealing cover 31, until the heating chamber 2 moves to the first predetermined position 103. The first predetermined position 103 refers to the position where the top of the heating chamber 2 has moved a certain distance upward from the second predetermined position 104 toward the outer cover 32 in the axial direction of the heat-not-burning device.

[0091] When the heating chamber 2 reaches the first predetermined position 103, the pressure relief valve 105 between the bottom outer edge of the sealing cover 31 and the top outer edge of the heating chamber 2 is tightly closed, that is, the pressure relief valve 105 is closed. At this time, the sealing cover 31 just tightly seals the heating chamber 2 with the cylinder 22. Correspondingly, the flow path between the airflow channel 33 and the cylinder 22 is also closed, thereby providing a heating environment for the substance 101 to be heated in the cylinder 22 that is isolated from the outside air.

[0092] When the flow path between the airflow channel 33 and the cylinder 22 is closed, that is, when the heating chamber 2 is tightly sealed at the bottom outer edge of the sealing cover 31, the heating non-combustible device can start to control the heating chamber 2 to heat the substance 101 to be heated in the cylinder 22 until the substance 101 to be heated is heated to the predetermined temperature.

[0093] When the substance 101 to be heated is heated to the predetermined temperature, please refer to... Figure 9 and Figure 10 The heating non-combustible device control drive device 4 drives the heating chamber 2 from the first predetermined position 103 toward the direction of disengaging from the sealing cover 31, that is, the heating chamber 2 moves downward along the axial direction of the heating non-combustible device until the heating chamber 2 moves back to the second predetermined position 104. It should be noted that, in specific implementation, the predetermined temperature can refer to the atomization temperature at which the substance to be heated 101 can generate aerosol without combustion, or it can refer to the atomization critical temperature at which the substance to be heated 101 is preheated to not generate aerosol. This embodiment does not impose specific limitations on this. For example, assuming that the atomization temperature at which the substance to be heated 101 can generate aerosol without combustion is 320°C, then the atomization critical temperature can be 200°C, 250°C, 300°C, 310°C, etc. When the heating chamber 2 returns to the second predetermined position 104, the pressure relief valve 105 is reopened. At this time, the flow path between the airflow channel 33 and the cylinder 22 is connected, so the user can perform the inhalation action.

[0094] In this embodiment of the application, at least one air inlet 3221 is provided on the outer cover 32 to allow outside air to enter the outer cover 32, and the air inlet 3221 is connected to the receiving cavity 3211 through the airflow channel 33.

[0095] like Figure 9-10 As shown, assuming that the substance 101 to be heated in the cylinder 22 has been heated to a temperature that can generate aerosol, when the user bites the filter 102 to suck it out, outside air can enter the outer cover 32 from the air inlet 3221 on the outer cover 32 and form an airflow in the airflow channel 33. Driven by the airflow, the aerosol generated after the substance 101 to be heated is discharged through the airflow channel 33 between the sealing cover 31 and the outer cover 32 into the receiving cavity 3211 containing the filter 102. The aerosol is then filtered by the filter 102 and inhaled by the user.

[0096] It should be noted that the substance to be heated 101 can be a low-temperature non-combustible herbal substance. The herbal product with the filter tip 102 separated from the herbal substance provided in this application embodiment is completely different from the structure of the low-temperature non-combustible cigarettes currently on the market. The low-temperature non-combustible cigarettes currently on the market have a structure in which the filter tip and the herbal substance are integrated.

[0097] The heat-not-burning device provided in this application embodiment is suitable for herbal products where the filter tip is separated from the substance to be heated. In the technical solution of this embodiment, when the herbal substance 101 is heated, the cylinder 22 containing the heating chamber 2 is covered and sealed by the sealing cap 31. That is, the driving device 4 drives the heating chamber 2 to move from the second predetermined position 104 to the first predetermined position 103, and the pressure relief valve 105 is in the closed state. At this time, the substance to be heated is in a heating environment isolated from the outside air. As heating proceeds, the pressure inside the cylinder 22 increases with the temperature, so that the substance to be heated can be in a closed and high-pressure (greater than one standard atmosphere) heating environment. Because the hot air inside the cylinder 22 is not easily diffused outward in the closed heating environment, and the temperature is more easily raised in the high-pressure heating environment, the herbal substance can be quickly heated to the predetermined temperature. When the substance to be heated generates an aerosol and is heated to the predetermined temperature, the drive device 4 immediately drives the heating chamber to reset from the first predetermined position 103 to the second predetermined position 104. The pressure relief valve 105 opens, and the cylinder 22 is reconnected to the airflow channel 33 through the pressure relief valve 105, allowing the user to bite the filter 102 and inhale. This structural design provides a sealed, high-pressure heating environment for the substance to be heated 101 during the heating and atomization process, thereby quickly heating the substance to be heated 101 to the required temperature, effectively shortening the waiting time for the user to inhale the "first puff" of aerosol and improving the user experience.

[0098] Further, please refer to Figures 5 to 10 In some embodiments of this application, a sealing ring 23 is also fitted around the top outer edge of the heating chamber 2. The sealing ring 23 and the bottom outer edge of the sealing cover 31 form a pressure relief valve 105. In specific implementations, the material of the sealing ring 23 can be silicone, silicone rubber, etc. It should be noted that if the top outer edge of the heating chamber 2 is made of a material with sealing properties, the sealing ring 23 may not be fitted around the top outer edge of the heating chamber 2. This is not specifically limited here.

[0099] In addition, please refer to Figures 4 to 10 In an exemplary embodiment of the present invention, a bottom plate 51 and a first telescopic member 52 are installed inside the cylinder 22, that is, the bottom plate 51 and the first telescopic member 52 are installed inside the cavity 220 of the cylinder 22. The bottom plate 51 is adapted to the cavity 220 of the cylinder 22. One end of the first telescopic member 52 is connected to the end of the bottom plate 51 facing away from the material to be heated 101, and the other end of the first telescopic member 52 is connected to the bottom wall of the heating chamber 2 facing the bottom plate 51. The bottom plate 51 can move up and down along the axial direction of the cylinder, so that the material to be heated 101 in the cavity 220 of the cylinder 22 can move upward or downward.

[0100] First refer to Figure 5 Before using the heated non-combustible device, the sealing assembly 3 and the heating chamber 2 are in the open state, by Figure 5 It can be seen that the first telescopic component 52 is in a fully extended state at this time.

[0101] Next refer to Figure 6 You can also refer to Figure 9 and Figure 10 When the substance to be heated 101 is loaded into the cavity 220 of the cylinder 22 and the sealing assembly 3 is closed, the sealing cover 31 presses down on the substance to be heated 101, causing the bottom plate 51 to move down and the first telescopic member 52 to be compressed. At this time, the lower outer edge of the sealing cover 31 is separated from the upper outer edge of the heating chamber 2, that is, the pressure relief valve 105 is opened, and the airflow channel 33 is connected to the heating chamber 2. When a sealing ring 23 is fitted on the top outer edge of the heating chamber 2, the sealing ring 23 is separated from the bottom edge of the sealing cover 31. Furthermore, in this state, the top edge of the heating chamber 2 is in the second predetermined position 104 in the axial direction of the heating non-combustible device.

[0102] In this embodiment, the heating chamber 2 is equipped with a sealing ring 23 on its top, and the substance to be heated 101 is a low-temperature non-combustible herbal material. It should be noted that when the sealing ring 23 is fitted around the top edge of the heating chamber 2, then... Figure 6 As shown, the sealing ring 23 is in the second predetermined position 104 in the axial direction of the heating non-combustible device.

[0103] Next refer to Figure 7 and Figure 8 In order to heat and atomize the herbal material in the heating chamber 2, the heating chamber 2 is moved upward along the axial direction of the heating non-combustible device towards the sealing cover 31, driven by the driving device 4, until the heating chamber 2 moves to the position where the sealing ring 23 is located. Figure 7 The upward movement stops at the first predetermined position 103 shown. For ease of understanding, this application... Figure 6 and Figure 7 Both are marked with a first predetermined position 103 and a second predetermined position 104, but... Figure 6 The middle sealing ring 23 is actually located at the second predetermined position 104, while Figure 7 The middle sealing ring 23 is actually located at the first predetermined position 103.

[0104] During this process, the upper surface of the material to be heated 101 is blocked by the sealing cap 31, causing the bottom plate 51 to move further downward and the first telescopic member 52 to be further compressed. At this time, the pressure relief valve 105 is closed, that is, the sealing ring 23 and the bottom edge of the sealing cap 31 are tightly closed to each other. At this time, the flow path between the airflow channel 33 and the heating chamber 2 is closed and not connected. In this state, as mentioned above, the heating non-combustible device is started to heat the herbal material to the predetermined temperature.

[0105] Final Reference Figure 9 and Figure 10 After the herbal material is heated to a predetermined temperature, the drive device 4 controls the heating chamber 2 to move downwards along the axial direction of the heating non-combustible device away from the sealing cover 31, until the sealing ring 23 moves down from the first predetermined position 103 to the second predetermined position 104. Then, the bottom plate 51 of the heating chamber 2 moves upwards again, returning to the state before the heating chamber 2 moved upwards. The first telescopic member 52 extends again from its previous compressed state, returning to the state before the heating chamber 2 moved upwards. At the same time, the sealing ring 23 and the bottom outer edge of the sealing cover 31 separate again, the pressure relief valve 105 opens, and the airflow channel 33 and the heating chamber 2 are reconnected. At this time, the user can perform a suction action.

[0106] like Figure 5 As shown, after the user finishes using the product and opens the sealing assembly 3, the sealing cap 31 releases the pressure on the herbal material, causing the first telescopic member 52 to extend and return to its original shape. The bottom plate 51 moves upward, and the residue inside the cylinder 22 is also exposed a certain distance from the cavity 220 of the cylinder 22 as the bottom plate 51 moves upward. This allows the user to easily remove the residue from the cylinder 22, which is the used herbal material. The distance the residue protrudes from the cylinder 22 can be controlled by adjusting the telescopic distance of the first telescopic member 52, which is designed according to actual usage requirements and is generally 2-3 mm.

[0107] It should be noted that, in the specific implementation of this embodiment, the first telescopic member 52 can be a spring, a sheet, an elastic band, or other components with good elastic properties, or it can be a lifting rod with telescopic function. This embodiment does not impose specific limitations on this.

[0108] Further, please refer to Figure 2 as well as Figure 4-12 In an exemplary embodiment of the present invention, the heated non-combustible device further includes a second telescopic member 7 capable of telescopic movement along the length direction of the outer casing 1, the second telescopic member 7 being installed between the heating chamber 2 and the outer casing 1. Wherein, as... Figure 4As shown, when the cap assembly 3 is in the open state, one end of the second telescopic member 7 extends out from the opening 11 and separates from the bottom of the outer cover 32. When the cap assembly 3 closes the opening 11, as shown... Figure 6 As shown, one end of the second telescopic member 7 abuts against the bottom of the outer cover 32 and retracts into the opening 11 due to the pressure from the bottom of the outer cover 32. Thus, when the outer cover 32 is connected to one end of the outer shell 1 by a hinge, the addition of the second telescopic member 7 inside the outer shell 1 to support the opened sealing assembly 3 allows the sealing assembly 3 to be in a semi-open state without closing naturally due to its own weight or other factors. This is beneficial because after the user completes the aerosol extraction and opens the sealing assembly 3, the heating chamber 2 can be fully open, allowing the heating chamber 2 to dissipate heat more quickly. This helps reduce the risk of the user being burned by the residual heat of the heating chamber 2 when removing the residue from the cylinder 22.

[0109] It should be noted that, in the specific implementation of this embodiment, the second telescopic component 7 can be a spring, a sheet, an elastic band, or other components with good elastic properties, or it can be a lifting rod with telescopic function. This embodiment does not impose specific limitations on this.

[0110] In some alternative embodiments, the second telescopic member 7 can be configured such that the sealing assembly 3 can be in a semi-open state after the sealing assembly 3 is opened: Specifically, please refer to Figure 4-12 The second telescopic member 7 includes a support portion 71 and an elastic portion 72 connected to one end of the support portion 71, as illustrated. Figure 11 and Figure 12 As shown, the support part 71 is sheet-shaped, and the elastic part 72 is mesh-shaped. When the sealing assembly 3 is fully open, one end of the second telescopic member 7 extends out from the opening 11 and separates from the bottom of the outer cover 32. When the outer cover 32 is half-open, the end of the support part 71 away from the elastic part 72 abuts against the bottom of the outer cover 32 to support the sealing assembly 3. When the sealing assembly 3 is closed in the opening 11, the end of the support part 71 away from the elastic part 72 abuts against the bottom of the outer cover 32 and retracts into the opening 11 due to the pressure from the bottom of the outer cover 32.

[0111] The working principle of the second telescopic component 7 in this embodiment is as follows:

[0112] Please refer to Figure 4-6 When the user applies force to close the sealing assembly 3 onto the opening 11, the lower end of the outer cover 32 presses against the upper end of the support portion 71. The elastic portion 72 contracts under pressure, causing the upper end of the support portion 71 to retract into the opening 11 and abut against the lower end of the outer cover 32. Please refer to... Figure 6-8When the driving device 4 drives the heating chamber 2 to move upward from the second predetermined position 104 to the first predetermined position 103 so that the sealing cover 31 closes the cylinder 22, since the second telescopic member 7 is installed on the heating chamber 2, the second telescopic member 7 will move upward along with the heating chamber 2. At the same time, since the support part 71 always remains in contact with the outer cover 32 during the upward movement of the heating chamber 2, the elastic part 72 will be further compressed during the upward movement of the heating chamber 2 without causing interference to the upward movement of the heating chamber 2. Please refer to Figure 8-10 When the driving device 4 drives the heating chamber 2 to move downward from the first predetermined position 103 to the second predetermined position 104 so that the cylinder 22 connects with the airflow channel 33, the second telescopic member 7 will move downward along with the heating chamber 2. At this time, the elastic part 72 will return to the state before the heating chamber 2 moves upward, and the support part 71 will still remain in contact with the lower end of the outer cover 32. Please refer to Figure 4 and Figure 5 When the user opens the sealing assembly 3, the support part 71 is released from pressure. Under the action of the elastic restoring force of the elastic part 72, the upper end of the support part 71 extends out from the opening 11. If the sealing assembly 3 is flipped in the direction of closing the opening 11, the support part 71 can support the outer cover 32, and the sealing assembly 3 cannot close naturally and is in a semi-open state.

[0113] In this embodiment, it is understood that, in specific implementation, the second telescopic member 7 can be a one-piece molded structure or an assembled structure, and this embodiment does not impose specific limitations on this. Specifically, when the second telescopic member 7 is a one-piece molded structure, it can be integrally molded from an elastic material, such as nylon, polyester, polypropylene, or other elastic plastics, through injection molding. To improve the elastic performance of the elastic part 72, it can be designed with a wavy or mesh-like shape. When the second telescopic member 7 is an assembled structure, the upper end of the elastic part 72 can abut against the lower end of the support part 71. The elastic part 72 can be a spring, sheet metal, rubber band, or other device with good elastic properties.

[0114] Further, please refer to Figure 2-10 as well as Figure 17-20 In an exemplary embodiment of the present invention, the sealing cap 31 includes a connecting portion 311 and a capping portion 312 integrally connected to the connecting portion 311. The connecting portion 311 is fitted into the end of the receiving cavity 3211 near the opening 11, and a plurality of venting grooves 3111 are provided on the outer side wall of the connecting portion 311, which are arranged circumferentially at intervals 331 along the connecting portion 311. The venting grooves 3111 are respectively connected to the air inlet 3221 (see reference). Figure 10 and Figure 18), and is connected to the accommodation cavity 3211. Illustratively, the outer diameter of one end of the connecting portion 311 close to the cover portion 312 is greater than the outer diameter of the end of the connecting portion 311 away from the cover portion 312, and the outer diameter of the end of the connecting portion 311 close to the cover portion 312 is less than the outer diameter of the cover portion 312; combining Figure 3 、 Figure 4 和 Figure 17 shows that the cover portion 312 is disposed corresponding to the end of the cylindrical body 22 close to the opening 11, and referring to Figure 9 、 Figure 10 以及 Figure 18 , there is a gap 331 between the cover portion 312 and the inner wall of the outer cover body 32, and the gap 331 and the ventilation groove 3111 communicate with each other to form an air flow channel 33. Thus, as Figure 4-8 shows, when the outer cover body 32 closes the opening 11 of the outer shell body 1 and the driving device 4 drives the heating chamber 2 to move from the second predetermined position 104 to the first predetermined position 103, the cover portion 312 is in close contact with the end of the cylindrical body 22 close to the opening 11 to close the cavity 220 of the cylindrical body 22, that is, the heating chamber 2 is in close contact with the cover portion 312 of the sealing cover 31, so that the substance to be heated 101 in the cylindrical body 22 can be in a heating environment isolated from the outside air; as Figure 4 、 Figure 8 和 Figure 10 show, when the outer cover body 32 closes the opening 11 of the outer shell body 1 and the driving device 4 drives the heating chamber 2 to move from the first predetermined position 103 to the second predetermined position 104, the heating chamber 2 is separated from the cover portion 312 of the sealing cover 31, so that the cylindrical body 22 is connected to the air flow channel 33, so that the user can inhale the aerosol generated after the substance to be heated 101 is heated.

[0115] Further, please refer to Figure 3 、 Figure 8 、 Figure 10 以及 Figure 17-20 , in an exemplary embodiment of the present invention, a plurality of grooves 3112 are distributed on the end surface of the connecting portion 311 located in the accommodation cavity 3211, and each groove 3112 is in one-to-one correspondence and communication with each ventilation groove 3111. Thus, during use, even if the lower end surface of the filter tip 102 is in contact with the upper end surface of the connecting portion 311, due to the clearance function of the plurality of grooves 3112 having a clearance space, when the user performs a suction action, the aerosol can still smoothly enter the filter tip 102 along with the air flow and be inhaled by the user, thereby avoiding the filter tip 102 from being inserted too low and blocking the ventilation groove 3111.

[0116] Further, please refer to Figure 2 、 Figure 3 、 Figure 8 ]>以及 Figure 17-20In an exemplary embodiment of the present invention, the outer cover 32 includes a hollow first cover portion 321 and a hollow second cover portion 322 coaxially disposed with the first cover portion 321. One end of the first cover portion 321 is connected to one end of the second cover portion 322, and there is a gap 323 between the end face of the first cover portion 321 and the end face of the second cover portion 322. A plurality of air inlets 3221 are provided on the end face of the second cover portion 322 corresponding to the gap 323, arranged at circumferential intervals 331 along the second cover portion 322. A sealing cap 31 is disposed inside the second cover portion 322 and combined with... Figure 2-3 It can be seen that the second cover 322 is movably connected to one end of the outer casing 1, as illustrated, as shown in the diagram. Figure 2-3 As shown, the second cover 322 is hinged to one end of the outer shell 1 via a hinge 13.

[0117] In this embodiment, the outer cover 32, based on the above-described structural design, not only allows the air inlets 3221 to communicate with the outside by setting multiple air inlets 3221 on the end face of the second cover 322 corresponding to the gap 323, but also "hides" each air inlet 3221 within the gap 323, making it less noticeable to the user and thus improving the user's visual experience. In this embodiment, it should be noted that, in specific implementations, the outer cover 32 can be integrally formed or assembled; this embodiment does not impose specific limitations on this. For example, as... Figure 17-18 As shown, the first cover portion 321 and the second cover portion 322 can be integrally formed by injection molding or other methods; for example, such as Figures 19-20 As shown, the first cover 321 and the second cover 322 can be connected into one unit by an adaptive connection assembly method. In the illustration, the upper end of the second cover 322 and the lower end of the first cover 321 are matched and connected into one unit.

[0118] Further, please refer to Figures 1 to 4 In an exemplary embodiment of the present invention, the outer cover 32 is hinged to one end of the outer shell 1. A first locking member 61 is provided on the outer side wall of one end of the outer shell 1, and a second locking member 62 adapted to the first locking member 61 is provided on the outer cover 32. When the outer cover 32 closes the opening 11, the first locking member 61 and the second locking member 62 are locked together. This arrangement allows the user to easily open or close the opening 11 of the outer shell 1 during use. Specifically, when it is necessary to close the opening 11 of the outer shell 1, the outer cover 32 is flipped downwards and the first locking member 61 and the second locking member 62 are engaged to lock the outer cover 32, so that the outer cover 32 can reliably close the opening 11 of the outer shell 1; and when it is necessary to open the opening 11 of the outer shell 1, the first locking member 61 and the second locking member 62 are separated and the outer cover 32 is flipped upwards.

[0119] In this embodiment, the locking and unlocking of the outer cover 32 can be achieved using a first locking member 61 and a second locking member 62 with the following structural forms. Specifically, please refer to... Figure 1-5 The first locking element 61 includes an elastic element 611, a first base 612 fixed to the outer wall of the outer casing 1, and a push plate 613 rotatably connected to the first base 612 via a pivot. The elastic element 611 is installed between the end of the push plate 613 away from the outer cover 32 and the first base 612. The other end of the push plate 613 near the outer cover 32 has a first locking portion 6131. ​​The second locking element 62 includes a second base 621 fixed to the outer wall of the outer cover 32 and a second locking portion 622 disposed on the second base 621. When the outer cover 32 closes the opening 11, the first locking portion 6131 and the second locking portion 622 engage. This arrangement is as follows: Figure 3 As shown, when the outer cover 32 is closed, the first locking part 6131 can directly press against the second locking part 622 to lock the outer cover 32; and when it is necessary to open the outer cover 32, as... Figure 4 and Figure 5 As shown, by pressing the end of the button 613 away from the outer cover 32, the first locking part 6131 can be "pried up" so that the first locking part 6131 is disengaged from the second locking part 622 and the outer cover 32 is unlocked. At this time, the outer cover 32 is flipped upward so that the opening 11 of the outer shell 1 is in an open state that communicates with the outside.

[0120] Furthermore, in some specific embodiments, the structure of the heating chamber 2 can be a resistance heating chamber based on Joule's law, an induction heating chamber based on the principle of induction heating, or a conductive ceramic heating chamber based on conductive ceramics. This embodiment does not impose specific limitations on these aspects. When the heating chamber 2 is a resistance heating chamber or an induction heating chamber, it further includes a heating element 21, which can be arranged around the cylinder 22. Thus, the heat generated by the heating element 21 or the heat generated by the interaction between the heating element 21 and the cylinder 22 can be used to heat the substance 101, i.e., the herbal substance, inside the cylinder 22.

[0121] Optionally, in one specific embodiment, a resistance heating chamber with the following structural form can be used to heat the material 101 to be heated: Specifically, please refer to... Figure 2 , Figure 7 , Figure 11 and Figure 15 In an exemplary embodiment of the present invention, the heating element 21 includes one of a heating wire, a heating mesh, and a heating plate. See also, illustratively, [reference needed]. Figure 11 In this embodiment, the heating element 21 is a heating mesh 212. See also... Figure 15 The cylinder 22 includes a heat-conducting cylinder 225, a heat-insulating cylinder 223, and a heat-preserving cylinder 224. The heat-conducting cylinder 225 has a cavity 220 capable of accommodating the substance 101 to be heated (see reference). Figure 2 The heat insulation cylinder 223 is sleeved on the heat conduction cylinder 225, the heat insulation cylinder 224 is sleeved on the heat insulation cylinder 223, and the heating element 21 is wound around the heat conduction cylinder 225 and located between the heat insulation cylinder 223 and the heat conduction cylinder 225. Thus, when the heating element 21 is powered on and generates heat, the heat generated by the heating element 21 is conducted through the heat-conducting cylinder 225 to the substance 101 to be heated, thereby heating the substance 101 located inside the heat-conducting cylinder 225. At the same time, since the heat-conducting cylinder 225 is sequentially fitted with the heat-insulating cylinder 223 and the heat-preserving cylinder 224, the heat loss during the operation of the heating chamber 2 can be reduced, the heating effect of the heating chamber 2 can be improved, and the substance 101 to be heated inside the heat-conducting cylinder 225 can be heated to the predetermined temperature more quickly. Moreover, the setting of the heat-preserving cylinder 224 and the heat-insulating cylinder 223 can also prevent the residual heat of the heating element 21 and the heat-conducting cylinder 225 from being transferred to the outer shell 1 too much during the user's suction process, thus avoiding the user's "hot hand" discomfort.

[0122] In this embodiment, it is understood that the heat-conducting cylinder 225 is made of a heat-conducting material, such as ceramic or metal. The ceramic material can be conductive or insulating, and the metal material can be copper, aluminum, titanium, or an alloy (e.g., stainless steel). It should be noted that when the heat-conducting cylinder 225 is made of a conductive or heat-conducting material such as metal, to prevent short circuits in the heating element 21, the heating element 21 and the heat-conducting cylinder 225 are insulated from each other. For example, the heating element 21 can be insulated from the heat-conducting cylinder 225 by performing micro-arc oxidation insulation treatment. Alternatively, insulating varnish can be applied to the contact area between the heat-conducting cylinder 225 and the heating element 21. Of course, other methods can also be used to achieve phase insulation between the heating element 21 and the heat-conducting cylinder 225, as long as the heating element 21 can be electrically energized and heated normally without short circuits. This embodiment does not impose specific limitations on this.

[0123] In this embodiment, it is understood that both the heat insulation cylinder 223 and the heat insulation cylinder 224 are made of heat insulation materials, such as aerogel, foam, ceramic fiber and other heat insulation materials, as long as they can meet the usage requirements. This embodiment does not impose specific restrictions on them.

[0124] Alternatively, in another specific embodiment, an induction heating chamber with the following structural form can be used to heat the material 101 to be heated: Specifically, please refer to... Figure 2 , Figure 7 , Figure 12 and Figure 14In another exemplary embodiment of the present invention, the heating element 21 includes an electromagnetic induction coil 211, and the cylinder 22 includes a metal cylinder 221, an insulating cylinder 222, a heat insulation cylinder 223, and a heat-insulating cylinder 224. The metal cylinder 221 has a cavity 220 capable of accommodating the substance 101 to be heated (see reference). Figure 2 The insulating cylinder 222 is sleeved on the metal cylinder 221, the heat insulation cylinder 223 is sleeved on the insulating cylinder 222, the heat insulation cylinder 224 is sleeved on the heat insulation cylinder 223, and the electromagnetic induction coil 211 is wound on the insulating cylinder 222 and located between the heat insulation cylinder 223 and the insulating cylinder 222. Thus, when the electromagnetic induction coil 211 is connected to an AC power source, it generates an alternating magnetic field with a constantly changing direction. This causes eddy currents to be generated in the metal cylinder 221 located within the alternating magnetic field, resulting in a temperature rise. This heats the material 101 to be heated within the metal cylinder 221. The insulating cylinder 222 provides insulation between the electromagnetic induction coil 211 and the metal cylinder 221, preventing short circuits. The heat-insulating cylinder 224 and the heat-resistant cylinder 223 not only reduce heat loss during the operation of the heating chamber 2 and improve its heating effect, allowing the material 101 to be heated within the metal cylinder 221 to be heated to the predetermined temperature more quickly, but also prevent excessive heat transfer from the metal cylinder 221 to the outer casing 1 during suction, thus avoiding a "scalding" experience for the user. In this embodiment, it is understood that the metal cylinder 221 is made of metal materials, such as copper, aluminum, titanium, alloys (e.g., stainless steel); the insulating cylinder 222 is made of insulating materials, such as insulating ceramics, high-temperature resistant insulating plastics (e.g., polytetrafluoroethylene); the heat insulation cylinder 223 and the heat preservation cylinder 224 are both made of heat insulation materials, such as aerogel, foam, ceramic fiber, etc.

[0125] Alternatively, in another specific embodiment, a conductive ceramic heating chamber with the following structure can be used to heat the material 101 to be heated: Specifically, please refer to... Figure 16 In another exemplary embodiment of the present invention, the heating chamber 2 further includes a positive electrode wire 227 and a negative electrode wire 228, and the cylindrical body 22 includes a cylindrical conductive ceramic body 226, which has a cavity 220 capable of accommodating the substance 101 to be heated (see reference). Figure 2The positive electrode wire 227 is electrically connected to one end of the sidewall of the conductive ceramic body 226, and the negative electrode wire 228 is electrically connected to the other end of the conductive ceramic body 226. On the axial section of the conductive ceramic body 226, the end where the positive electrode wire 227 and the conductive ceramic body 226 are connected is diagonally opposite to the end where the negative electrode wire 228 and the conductive ceramic body 226 are connected. For example, assuming that the axial section of the conductive ceramic body 226 is rectangular, the end where the positive electrode wire 227 and the conductive ceramic body 226 are connected is simply referred to as the positive connection end, and the end where the negative electrode wire 228 and the conductive ceramic body 226 are connected is simply referred to as the negative connection end. Then the line connecting the positive connection end and the negative connection end can be approximately regarded as the diagonal of the rectangle.

[0126] In this embodiment, based on the above-described conductive ceramic heating chamber 2, when the positive electrode wire 227 and the negative electrode wire 228 are connected to the power supply, the current can flow fully through the outer periphery of the entire conductive ceramic body 226, so that the outer periphery of the conductive ceramic body 226 can be directly energized and heated, thereby realizing the heating of the material 101 to be heated in the conductive ceramic body 226. In this embodiment, it should be noted that in some optional implementations, the cylinder 22 may further include a heat insulation cylinder 224 and a heat insulation cylinder 223. The heat insulation cylinder 223 is sleeved on the outside of the conductive ceramic body 226, and the heat insulation cylinder 224 is sleeved on the outside of the heat insulation cylinder 223. Both the heat insulation cylinder 223 and the heat insulation cylinder 224 are made of heat insulation materials, such as aerogel, foam, ceramic fiber, etc. In this way, by adding a heat insulation cylinder 223 and a heat insulation cylinder 224 to the outside of the conductive ceramic body 226, not only can the heat loss of the heating chamber 2 during operation be reduced and the heating effect of the heating chamber 2 be improved, so that the substance 101 to be heated in the conductive ceramic body 226 can be heated to the temperature that can generate aerosol more quickly, but also can prevent the residual heat of the conductive ceramic body 226 from being transferred to the outer shell 1 too much during the user's suction process, thus avoiding the user's "hot hand" discomfort.

[0127] like Figure 3 , 6 As shown in Figures 8, 10-12, and 14-16, in the embodiments described above that include the heat insulation cylinder 223 and the heat preservation cylinder 224, it should be noted that, as Figure 2-12 As shown, in some application scenarios that include the aforementioned second telescopic component 7, to improve the ease of installation of the second telescopic component 7, such as... Figure 3 , 6 As shown in Figures 8 and 10, the second telescopic member 7 can be installed between the heat insulation cylinder 223 and the heat preservation cylinder 224. Specifically, the second telescopic member 7 can be fitted into the gap between the heat conducting cylinder 225 and the heat preservation cylinder 224, so that the second telescopic member 7 can smoothly extend and retract along the length direction of the outer shell 1. Furthermore, as... Figure 2-12As shown in 14-16, in some application scenarios that include the aforementioned sealing ring 23, in order to ensure that the sealing ring 23 can better correspond to the sealing cover 31, in specific implementations, such as... Figure 3 , 6 As shown in Figures 8 and 10, the sealing ring 23 can be fitted onto the top outer edge of the heat insulation cylinder 223.

[0128] Furthermore, in some specific embodiments, the entire heating chamber 2 can be moved between a first predetermined position 103 and a second predetermined position 104 along the length of the outer shell 1 in the following manner: Please refer to Figures 4 to 10 as well as Figure 13-16 In an exemplary embodiment of the present invention, the driving device 4 is fixedly connected to the side of the heating chamber 2 facing away from the opening 11. The driving device 4 includes any one of an electric push rod, an electro-hydraulic push rod, or a screw lifting mechanism. Thus, by using a mechanism capable of telescopic movement, such as an electric push rod, an electro-hydraulic push rod, or a screw lifting mechanism, as the driving device 4 in this embodiment, the heating chamber 2 can move between the first predetermined position 103 and the second predetermined position 104 as the driving device 4 telescopically moves. In this embodiment, in specific implementation, to enable the heating chamber 2 to reciprocate more smoothly along the length direction of the outer shell 1, a guide rail structure can be added between the inner wall of the outer shell 1 and the outer wall of the heating chamber 2. Specifically, the inner wall of the outer shell 1 is provided with protrusions 12 arranged along the length direction of the outer shell 1 (e.g., Figure 13 , Figures 8 to 10 As shown), a groove 2241 adapted to the protrusion 12 is provided on the outer wall of the heating chamber 2 (as shown). Figures 14 to 16 As shown, the slide groove 2241 and the protrusion 12 slide in cooperation, so that under the guidance of the slide groove 2241, the heating chamber 2 can reciprocate more smoothly along the length of the outer shell 1. In this embodiment, it is understood that the electric push rod, the electro-hydraulic push rod, and the lead screw lifting mechanism are all mature telescopic mechanisms in the art, which will be understood by those skilled in the art, and will not be described in detail here.

[0129] Furthermore, in some other specific embodiments, the entire heating chamber 2 can be moved between the first predetermined position 103 and the second predetermined position 104 along the length direction of the outer shell 1 in the following manner: Please refer to Figure 8 , Figure 10 as well as Figure 13-16In another exemplary embodiment of the present invention, a protrusion 12 is provided on the inner wall of the outer shell 1 along the length direction of the outer shell 1, and a sliding groove 2241 adapted to the protrusion 12 is provided on the outer wall of the heating chamber 2. The sliding groove 2241 and the protrusion 12 are slidably engaged. The driving device 4 includes a driving motor 41. A threaded hole 2242 is provided on the side of the heating chamber 2 facing away from the opening 11. The output shaft 411 of the driving motor 41 is threadedly engaged with the threaded hole 2242. That is, the output shaft 411 of the driving motor 41 has an external thread, and the inner wall of the threaded hole 2242 has an internal thread. When the output shaft 411 of the driving motor 41 is engaged in the threaded hole 2242, the external thread of the output shaft 411 meshes with the internal thread of the threaded hole 2242.

[0130] In this embodiment, based on the above structural design, the rotational motion of the drive motor 41 can be converted into the linear motion of the heating chamber 2, enabling the entire heating chamber 2 to move between the first predetermined position 103 and the second predetermined position 104 along the length direction of the outer shell 1. Specifically, when the output shaft 411 of the drive motor 41 rotates, since the bottom of the heating chamber 2 is threadedly engaged with the output shaft 411 of the drive motor 41 and the circumferential degree of freedom of the heating chamber 2 is constrained by the slide groove 2241, the rotational force generated by the drive motor 41 will eventually force the heating chamber 2 to slide up or down along the protrusion 12. That is, by controlling the output shaft 411 of the drive motor 41 to rotate in both directions, the entire heating chamber 2 can be driven to slide up or down along the protrusion 12.

[0131] Further, please refer to Figure 4-10 In an exemplary embodiment of the present invention, the heated non-combustible device further includes a control switch 81, a control circuit board 82, and a battery 9. The control switch 81 is disposed on the outer wall of the outer casing 1, and the control circuit board 82 and the battery 9 are both installed inside the outer casing 1. The control circuit board 82 is electrically connected to the heating chamber 2, the driving device 4, the control switch 81, and the battery 9, respectively. The control circuit board 82 can be used to control the operation of the heating chamber 2 and the driving device 4, thereby realizing the intelligent operation of the heated non-combustible device. Specifically, during use, the user can start the heated non-combustible device by operating the control switch 81, for example... Figure 6-8 As shown, when it is necessary to heat the substance 101 inside the cylinder 22, the control switch 81 can be turned on. At this time, the control circuit board 82 will receive a corresponding signal and control the drive device 4 to drive the heating chamber 2 to move closer to the sealing cover 31 until the sealing cover 31 closes the cylinder 22 of the heating chamber. Next, please refer to... Figure 7 and Figure 8The control circuit board 82 controls the battery 9 to supply power to the heating chamber 2, causing the heating chamber 2 to generate heat and heat the material 101 to be heated in the cylinder 22 until the material 101 is heated to a predetermined temperature. Figure 8-10 As shown, when the substance to be heated 101 is heated to a predetermined temperature, the control circuit board 82 controls the drive device 4 to drive the heating chamber 2 to move in the direction of disengaging from the sealing cover 31, so that the cylinder 22 of the heating chamber 2 is reopened, at which point the user can perform the inhalation action. In this embodiment, it should be noted that the structure of the control switch 81 can be a push-button switch or a touch screen switch. This embodiment does not impose specific limitations on this. In illustrative purposes, the control switch 81 in this embodiment is a push-button switch.

[0132] Further, please refer to Figure 4-10 In an exemplary embodiment of the present invention, the heated non-combustible device further includes a temperature sensor (not shown in the figure) disposed on the heating chamber 2, and the temperature sensor is electrically connected to the control circuit board 82. Thus, by adding a temperature sensor to the heating chamber 2, the operating temperature of the heating chamber 2 can be monitored more accurately in real time during the heating of the substance to be heated 101, so that when the substance to be heated 101 is heated to a predetermined temperature, the heating chamber 2 can be controlled to stop working and the driving device 4 can be controlled to drive the heating chamber 2 to move in the direction of disengaging from the sealing cover 31.

[0133] Correspondingly, please refer to Figures 1 to 21 The present invention also provides a heating method for a non-combustible heating device, applicable to any of the non-combustible heating devices described above. Figure 21 This is a schematic flowchart of a heating method for a non-combustible heating device according to an embodiment of the present invention, as shown below. Figure 21 As shown, the heating method includes the following steps:

[0134] Step 2101: Receive the start command and control the drive device 4 to move the heating chamber 2 to the first predetermined position 103 according to the start command, so that the sealing cover 31 closes the cylinder 22.

[0135] Specifically, the user can trigger the start command by operating the control switch 81. When the control circuit board 82 receives the start command, the control circuit board 82 controls the drive device 4 to drive the heating chamber 2 to move upward from the initial second predetermined position 104 until it reaches the first predetermined position 103. When the heating chamber 2 moves to the first predetermined position 103, the pressure relief valve 105 formed between the bottom outer edge of the sealing cover 31 and the top outer edge of the heating chamber 2 is closed, and the flow path between the airflow channel 33 and the heating chamber 2 is also closed. That is, at this time, the bottom of the sealing cover 31 is tightly connected to the top of the heating chamber 2, thus sealing the cylinder 22.

[0136] Step 2102: Control the heating chamber 2 to heat the material 101 to be heated in the cylinder 22 to a predetermined temperature;

[0137] Specifically, after the sealing cap 31 closes the cylinder 22, the control circuit board 82 controls the heating chamber 2 to be energized and heated to heat the substance 101 inside the cylinder 22 until the substance 101 inside the cylinder 22 is heated to a predetermined temperature. It should be noted that the predetermined temperature can be the atomization temperature of the substance 101 or the atomization critical temperature of the substance 101. This embodiment does not impose specific limitations on this. The atomization temperature refers to the temperature at which the substance 101 can generate an aerosol without combustion, while the atomization critical temperature is lower than the atomization temperature. For example, assuming the atomization temperature at which the substance 101 can generate an aerosol without combustion is 320°C, the atomization critical temperature could be 200°C, 250°C, 300°C, 310°C, etc. Furthermore, whether the substance 101 inside the cylinder 22 has been heated to the predetermined temperature can be determined by installing a temperature sensor on the heating chamber 2, or the control circuit board 82 can also determine this by monitoring the change in the resistance value of the heating chamber 2. Figure 3 , Figure 14 and Figure 15 As shown, in some embodiments, when the heating chamber includes a heating element 21, the control circuit board 82 can determine whether the material to be heated 101 inside the cylinder 22 has been heated to a predetermined temperature by monitoring the change in the resistance value of the heating element 21. For example, such as... Figure 2 and Figure 16 As shown, in some embodiments, when the heating chamber includes a conductive ceramic body 226, the control circuit board 82 can determine whether the material to be heated 101 inside the cylinder 22 has been heated to a predetermined temperature by monitoring the change in resistance of the conductive ceramic body 226. Of course, other temperature monitoring methods can also be used, and this embodiment does not impose specific limitations on them. It should be noted that the method by which the control circuit board 82 monitors the change in resistance of the heating chamber 2 to achieve temperature monitoring is well known to those skilled in the art and will not be described in detail here.

[0138] Step 2103: When the substance to be heated 101 is heated to a predetermined temperature, the control drive device 4 drives the heating chamber 2 to move to the second predetermined position 104 so that the heating chamber 2 is separated from the sealing cover 31 and connected to the airflow channel 33.

[0139] Specifically, when the substance to be heated 101 is heated to a predetermined temperature, the control circuit board 82 controls the drive device 4 to drive the heating chamber 2 to reset, that is, to drive the heating chamber 2 from the first predetermined position 103 to the second predetermined position 104, so that the heating chamber 2 is separated from the sealing cover 31, the pressure relief valve 105 is reopened, so that the airflow channel 33 is connected to the cylinder 22 again, and the user can then perform the inhalation action.

[0140] In this embodiment, based on the above steps, the heating method of this embodiment can achieve the same technical effect as the above-described heating non-combustible device, and will not be repeated here. It should be noted that other contents of the heating method of this embodiment can be referred to the above description of the heating non-combustible device, and will not be repeated here.

[0141] Further, please refer to Figure 22 In another exemplary embodiment of the present invention, steps 2201 to 2203 are the same as those described above. Figure 21 Steps 2101 to 2103 in the embodiment are similar and will not be described in detail here. After step 2203, step 2204 is also included:

[0142] Step 2201: Receive the start command and control the drive device 4 to move the heating chamber 2 to the first predetermined position 103 according to the start command, so that the sealing cover 31 closes the cylinder 22.

[0143] Step 2202: Control the heating chamber 2 to heat the material 101 to be heated inside the cylinder 22 to a predetermined temperature;

[0144] Step 2203: When the substance to be heated 101 is heated to a predetermined temperature, the control drive device 4 drives the heating chamber 2 to move to the second predetermined position 104 so that the heating chamber 2 is separated from the sealing cover 31 and connected to the airflow channel 33.

[0145] Step 2204: Send a prompt message to the user to prompt them to perform the inhalation operation.

[0146] In this embodiment, the aforementioned prompting information can be one or more of sound prompts, text prompts, and light prompts, as long as the prompting effect is achieved. This embodiment does not impose specific limitations on this. It is understood that when the prompting information is sound, the heated non-combustible device may further include a speaker electrically connected to the battery 9; when the prompting information is text, the heated non-combustible device may further include a display screen electrically connected to the battery 9; and when the prompting information is light, the heated non-combustible device may further include an indicator light electrically connected to the battery 9. In this embodiment, after the heating chamber 2 completes the heating and atomization of the substance 101 to be heated and resets, a prompting information is issued to the user to remind them to perform the inhalation operation in a timely manner, thereby improving the user experience.

[0147] Furthermore, in yet another exemplary embodiment of the present invention, after step 2204 described above, the heating method of this embodiment may further include:

[0148] Step 2205: Receive a heating command and control the heating chamber 2 to heat the material 101 to be heated in the cylinder 22 to the atomization temperature according to the heating command.

[0149] In this embodiment, in some implementations, the user can trigger the heating command by operating the control switch 81 again. In other implementations, an airflow sensor connected to the control circuit board 82 can be installed on the flow path between the cylinder 22 and the receiving cavity 3211 to trigger the heating command. This embodiment does not impose specific limitations on this. It can be understood that when an airflow sensor is used to trigger the heating command, the airflow sensor can be connected to the control circuit board 82 wirelessly via Bluetooth or wired via a wire. When the control circuit board 82 receives the heating command, the control circuit board 82 controls the heating chamber 2 to heat the substance 101 to be heated in the cylinder 22 to the atomization temperature to continuously generate aerosol for the user to inhale.

[0150] In this embodiment, it is understood that when the control drive device 4 drives the heating chamber 2 to move to the second predetermined position 104 and separates the heating chamber 2 from the sealing cover 31, if the substance to be heated 101 has been heated to the atomization temperature that can generate aerosol, then a portion of the substance to be heated 101 will generate a certain amount of aerosol due to heat atomization. When the user performs a suction action, this aerosol can be filtered by the filter nozzle 102 and inhaled by the user. However, since the substance to be heated 101 has not been fully atomized at this time, the user will not be able to continuously inhale the aerosol. Based on this consideration, this embodiment, after the control circuit board 82 receives the heating command, re-controls the heating chamber 2 to heat the substance to be heated 101 in the cylinder 22 to the atomization temperature, thereby fully atomizing the substance to be heated 101 in the cylinder 22 and enabling the user to continuously inhale the aerosol. If the substance to be heated 101 is not heated to the atomization temperature but is preheated to the atomization critical temperature, then the substance to be heated 101 will not produce aerosol. Therefore, in order to ensure that the user can inhale aerosol when performing the inhalation action, this embodiment controls the heating chamber 2 to heat the substance to be heated 101 in the cylinder 22 to the atomization temperature after receiving the heating command from the control circuit board 82. This allows the user to continuously inhale aerosol. Moreover, since the substance to be heated 101 has been preheated, during the process of controlling the heating chamber 2 to heat the substance to be heated 101 in the cylinder 22 to the atomization temperature, the substance to be heated 101 can be quickly heated to a state that can produce aerosol, thereby effectively shortening the waiting time required for the user to inhale the "first puff" of aerosol.

[0151] It should be noted that other aspects of the heating non-combustible device and its heating method disclosed in this invention can be found in the prior art, and will not be repeated here.

[0152] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
