Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to a heating non-combustion device. Background Technology

[0002] Heated non-combustible devices, also known as low-temperature non-combustible heating devices, are electronic devices that atomize herbal products (such as low-temperature non-combustible cigarettes) at low temperatures to form an inhalable aerosol. The atomization temperature of low-temperature non-combustible herbal products is generally between 200℃ and 400℃, while the atomization temperature of low-temperature non-combustible cigarettes is between 300℃ and 320℃. Compared with traditional combustible cigarettes, heated non-combustible devices operate at lower temperatures, and the harmful components in the aerosol they produce are far lower than those in traditional combustible cigarettes. Therefore, using heated non-combustible devices can reduce the adverse effects of traditional combustible cigarettes on the human body.

[0003] Currently, the heating components of heated non-combustible devices on the market are classified according to their heating method, generally into resistance heating components and electromagnetic induction heating components. Among them, electromagnetic induction heating components typically include an induction coil and an induction element placed inside the induction coil.

[0004] However, commercially available sensors are generally made of magnetic metal materials, and their disposal after damage can cause environmental pollution. Furthermore, during the heating and atomization of herbal products using heat-not-burn devices, the heating temperature is difficult to control, leading to incomplete atomization or burning. For example, if the heating temperature is below the required atomization temperature, the herbal product will not atomize properly; if the heating temperature exceeds the required atomization temperature, the herbal product will burn. This not only wastes the herbal product but also affects the user's vaping experience. Utility Model Content

[0036] Compared with the prior art, the beneficial effects of this utility model are:

[0037] The heated non-combustible device provided by this utility model includes a shell, a sleeve, an induction coil, a ceramic induction heating element, a temperature measuring element, and a control element. The shell has an opening for placing the herbal product to be heated and atomized.

The induction coil is located inside the shell and surrounds the outside of the sleeve along its axial direction. The ceramic induction heating element is located inside the heating chamber and is in direct contact with the herbal product. The ceramic induction heating element is electromagnetic; therefore, when the induction coil generates a changing current due to energization, a changing magnetic field is generated in the area formed by the coil itself and the surrounding sleeve. This changing magnetic field causes electromagnetic coupling in the ceramic induction heating element, thereby generating an induced current. The ceramic induction heating element then transfers the heat generated by the induced current to the herbal product, thus heating and atomizing it. The temperature measuring element is installed inside the shell and is used to detect the heating temperature of the ceramic induction heating element. The control element is also installed inside the shell and is electrically connected to both the induction coil and the temperature measuring element. Thus, compared to induction heating elements made of all-metal magnetic materials, the ceramic induction heating element in this embodiment is made of more environmentally friendly ceramic materials. Therefore, it can reduce the pollution to the environment caused by the ceramic induction heating element after it is damaged and discarded. Moreover, compared to induction heating elements made of all-metal magnetic materials, the ceramic induction heating element in this embodiment has a lower cost, which can also reduce the production cost of the ceramic induction heating element.

[0038] Furthermore, in the heated non-combustible device provided in this application embodiment, by setting a control component and a temperature measuring component electrically connected to the control component, the heating temperature of the ceramic induction heating element can be controlled within the temperature range required for the atomization of the herbal product. This helps to prevent the heating temperature of the ceramic induction heating element from being higher than the atomization temperature required for the herbal product, thus avoiding scorching the herbal product and producing a burnt smell. At the same time, it helps to prevent the heating temperature of the ceramic induction heating element from being lower than the atomization temperature required for the herbal product, resulting in insufficient atomization of the herbal product, thereby causing waste of the herbal product and affecting the user's taste. Therefore, this technical solution helps to improve the user's smoking experience and reduce waste of herbal products. Attached Figure Description

[0065] Reference Figures 1 to 8 , Figures 13 to 15 As shown, this embodiment of the present invention provides a heat-not-burning device 10, which includes a housing 1, a sleeve 2, an induction coil 4, a ceramic induction heating element 31, a temperature measuring element 33, and a control element 5. The housing 1 has an opening 11 for placing the herbal product 9 to be heated and atomized. The sleeve 2 is installed inside the housing 1, and a heating chamber 21 communicating with the opening 11 is provided inside the sleeve 2 for placing the herbal product 9. The induction coil 4 is located inside the housing 1 and is arranged around the outside of the sleeve 2 along its axial direction. The ceramic induction heating element 31 is located inside the heating chamber 21 and is in direct contact with the herbal product 9. The ceramic induction heating element 31 is electromagnetic and generates an induced current through electromagnetic coupling with the energized induction coil 4, transferring the heat generated by this induced current to the herbal product 9, thereby heating and atomizing the herbal product 9. The temperature measuring element 33 is installed inside the housing 1 and is used to detect the heating temperature of the ceramic induction heating element 31. The control element 5 is installed inside the housing 1, and the control element 5 is electrically connected to the induction coil 4 and the temperature measuring element 33 respectively.

[0066] In this embodiment, the electromagnetic coupling between the ceramic induction heating element 31 and the energized induction coil 4 means that when the induction coil 4 generates a changing current due to energization, a changing magnetic field is generated within the area formed by the induction coil 4 itself and the surrounding sleeve 2 (i.e., inside the induction coil 4). The ceramic induction heating element 31, located inside the heating chamber 21, generates an induced current by sensing this changing magnetic field. The ceramic induction heating element 31 then transfers the heat generated by the induced current to the herbal product 9 through thermal conduction, thereby heating and atomizing the herbal product 9. When the heating temperature of the ceramic induction heating element 31 reaches the temperature required for the atomization of the herbal product 9, the herbal product 9 is heated and atomized to produce an aerosol that can be inhaled by the user. It should be noted that the current in the induction coil 4 can be alternating current or changing direct current, as long as it can generate a changing current in the induction coil 4 and thus a changing magnetic field; this embodiment does not impose any specific limitations.

[0067] It should be noted that the induction coil 4 can be configured to be wound and fixed to the outer peripheral wall of the sleeve 2 along the axial direction of the sleeve 2, or it can be configured to be spaced apart from the outer peripheral wall of the sleeve 2 along the axial direction of the sleeve 2. For example, in this embodiment, a fixing bracket (not shown) can be fitted on the outer peripheral wall of the sleeve 2, and then the induction coil 4 can be installed and fixed on the fixing bracket along the axial direction of the sleeve 2 to make the installation of the induction coil 4 more stable. As long as the usage requirements are met, the specific configuration is not limited here.

[0068] In this embodiment, during the heating and atomization of the herbal product 9, the temperature measuring element 33 detects the heating temperature of the ceramic induction heating element 31 and sends the detected heating temperature of the ceramic induction heating element 31 to the control element 5 in the form of an electrical signal. The control element 5 controls the temperature of the ceramic induction heating element 31 based on the received heating temperature. Specifically, in this embodiment, assuming that the temperature range required for the atomization of the herbal product 9 is a target temperature range, when the heating temperature of the ceramic induction heating element 31 is outside this target temperature range, the control element 5 controls the temperature of the ceramic induction heating element 31 until the heating temperature of the ceramic induction heating element 31 rises or falls back into the target temperature range, at which point the control element 5 stops controlling the temperature of the ceramic induction heating element 31.

[0069] Specifically, the control unit 5 controls the temperature of the ceramic induction heating element 31 in ways including but not limited to the following: adjusting the output power of the induction coil 4 to adjust the strength of the magnetic field, thereby adjusting the heating temperature of the ceramic induction heating element 31.

[0070] More specifically, when the heating temperature of the ceramic induction heating element 31 exceeds the maximum value within the target temperature range, the control unit 5 can reduce the output power of the induction coil 4 to weaken the magnetic field generated by the induction coil 4, thereby reducing the heating temperature of the ceramic induction heating element 31. This continues until the heating temperature of the ceramic induction heating element 31 falls within the target temperature range, at which point the control unit 5 stops temperature control of the ceramic induction heating element 31 and maintains the current output power of the induction coil 4. Conversely, when the heating temperature of the ceramic induction heating element 31 is less than the minimum value within the target temperature range, the control unit 5 can increase the output power of the induction coil 4 to enhance the magnetic field generated by the induction coil 4, thereby increasing the heating temperature of the ceramic induction heating element 31. This continues until the heating temperature of the ceramic induction heating element 31 rises within the target temperature range, at which point the control unit 5 stops temperature control of the ceramic induction heating element 31 and maintains the current output power of the induction coil 4.

[0071] It should also be noted that the aforementioned herbal product 9 can be a low-temperature non-combustible tobacco product, or a herbal substance (such as mugwort), or other types of aerosol-generating products, such as tobacco leaves or shredded tobacco. This can be determined according to the user's actual needs, and this embodiment does not impose specific limitations on it. The so-called low-temperature non-combustible tobacco product mainly refers to an aerosol-generating product made from materials such as shredded tobacco, tobacco particles, plant fragments, tobacco flavorings, and propylene glycol. Under low-temperature heating conditions, the nicotine and other flavoring substances inside the tobacco product can volatilize without producing solid particles, only generating atomized vapor. Low-temperature non-combustibility is actually a low-temperature dry distillation process, with a heating temperature generally between 200℃ and 400℃. Here, "low-temperature" refers to a heating temperature within the range of 200℃ to 400℃.

[0072] In addition, in some application scenarios, such as Figures 1 to 7 , Figure 13 and Figure 14 As shown, the herbal product 9 can be a columnar low-temperature non-combustible cigarette. In this embodiment, the lower end of the low-temperature non-combustible cigarette is inserted into the heating chamber 21 through the opening 11, and the upper end of the low-temperature non-combustible cigarette protrudes outside the outer shell 1.

[0073] In other application scenarios, the herbal product 9 can be loose tobacco leaves, herbs (not shown), etc. In this application scenario, the herbal product 9 can be directly put into the heating chamber 21 through the opening 11, and the heated non-combustible device 10 is also equipped with a mouthpiece (not shown) that communicates with the opening 11 so that the user can inhale.

[0074] As described above, in the technical solution of this embodiment, by providing an electromagnetic ceramic induction heating element 31 inside the heating chamber 21, the ceramic induction heating element 31 can generate an induced current through electromagnetic coupling with the energized induction coil 4, and transfer the heat generated by the induced current to the herbal product 9, thereby heating and atomizing the herbal product 9. Thus, compared to induction heating elements made of all-metal magnetic materials, the ceramic induction heating element 31 in this embodiment is made of a more environmentally friendly ceramic material, thereby reducing the environmental pollution caused by the ceramic induction heating element 31 after it is damaged and discarded. Furthermore, compared to induction heating elements made of all-metal magnetic materials, the ceramic induction heating element 31 in this embodiment has a lower cost, thus reducing the production cost of the ceramic induction heating element 31.

[0075] Furthermore, by setting up the control element 5 and the temperature measuring element 33 electrically connected to the control element 5, the heating temperature of the ceramic induction heating element 31 can be controlled within the temperature range required for the atomization of the herbal product 9. This atomization temperature range is typically 200℃ to 400℃. Specifically, the temperature range required for atomization of low-temperature non-combustible cigarettes is generally between 300℃ and 320℃, while the temperature range required for atomization of loose tobacco leaves and herbs is generally between 280℃ and 310℃. This helps prevent the heating temperature of the ceramic induction heating element 31 from exceeding the required atomization temperature of the herbal product 9, thus avoiding scorching the herbal product 9 and producing a burnt smell. It also helps prevent the heating temperature of the ceramic induction heating element 31 from being lower than the required atomization temperature of the herbal product 9, resulting in insufficient atomization of the herbal product 9, thus avoiding waste of the herbal product 9 and affecting the user's taste. Therefore, this technical solution helps improve the user's smoking experience and reduce the waste of the herbal product 9.

[0076] Furthermore, in specific implementations, the ceramic induction heating element 31 can be manufactured in the following ways:

[0077] In some embodiments, such as Figure 10As shown, the ceramic induction heating element 31 can be made of at least one magnetizable conductive metal material 200 and an electrically insulating ceramic material 100. Specifically, the magnetizable conductive metal material 200 can include at least one of iron, nickel, cobalt, and their alloys, without specific limitations here. The aforementioned "alloy" can be an iron-nickel alloy, an iron-cobalt alloy, a nickel-cobalt alloy, or an iron-nickel-cobalt alloy, without specific limitations here. Thus, when the ceramic induction heating element 31 is doped with at least one of the aforementioned magnetizable conductive metal materials 200, the ceramic induction heating element 31 becomes electromagnetic. When the induction coil 4 generates a changing current due to energization, a changing magnetic field is generated in the area formed by the induction coil 4 around itself and the surrounding sleeve 2. This changing magnetic field causes electromagnetic coupling in the ceramic induction heating element 31, generating an induced current. The ceramic induction heating element 31 then transfers the heat generated by the induced current to the herbal product 9, thereby heating and atomizing the herbal product 9.

[0078] Furthermore, by using a ceramic induction heating element 31 doped with at least one magnetizable conductive metal material 200, compared to a heating element that is not electromagnetic, in the heating non-combustible device 10 of this application embodiment, when the induction coil 4 generates a changing magnetic field due to the changing current generated by the energization, the ceramic induction heating element 31 can rapidly form a stronger current eddy current within itself due to electromagnetic induction, thereby increasing the heat generated by the ceramic induction heating element 31 per unit time, heating the atomized herbal product 9 more quickly and efficiently, and improving the user's inhalation experience and inhalation taste.

[0079] In this embodiment, the ceramic induction heating element 31 can be made by mixing a magnetizable conductive metal material 200 and an electrically insulating ceramic material 100. For example, the ceramic induction heating element 31 is made by mixing iron and an electrically insulating ceramic material. Of course, the ceramic induction heating element 31 can also be made by mixing two or more magnetizable conductive metal materials 200 and electrically insulating ceramic materials 100. For example, the ceramic induction heating element 31 is made by mixing iron, nickel, and an electrically insulating ceramic material 100. For example, in some application scenarios of this embodiment, when the content of the magnetizable conductive metal material 200 doped in the ceramic induction heating element 31 is low, the same type of magnetizable conductive metal material 200 can be doped into the ceramic induction heating element 31, or different types of magnetizable conductive metal materials 200 can be doped into the ceramic induction heating element 31 to increase the electromagnetic properties of the ceramic induction heating element 31. This allows the ceramic induction heating element 31 to generate a sufficiently large induced current due to the changing magnetic field generated by the induction coil 4, thereby generating enough heat to heat and atomize the herbal product 9, making the atomization of the herbal product 9 more complete.

[0080] In other embodiments, such as Figure 11As shown, the ceramic induction heating element 31 can also be made of a mixture of a non-magnetizable conductive metal material 300, an electrically insulating ceramic material 100, and a magnetic material 400. Specifically, the non-magnetizable conductive metal material 300 can include at least one of copper, aluminum, zinc, lead, tin, platinum, and their alloys, wherein the aforementioned "alloy" can be a copper-aluminum alloy, a copper-zinc alloy, a copper-lead alloy, an aluminum-zinc alloy, etc., and is not specifically limited here. The magnetic material 400 can include at least one of neodymium iron boron, samarium cobalt, or iron, nickel, cobalt, and their alloys, wherein the aforementioned "alloy" can be an iron-nickel alloy, an iron-cobalt alloy, a nickel-cobalt alloy, or an iron-nickel-cobalt alloy.

[0081] Thus, when the ceramic induction heating element 31 is doped with a non-magnetizable conductive metal material 300 and a magnetic material 400, the ceramic induction heating element 31 becomes electromagnetic. In this way, when the induction coil 4 generates a changing current due to energization, the induction coil 4 generates a changing magnetic field in the area formed by its own periphery and the surrounding sleeve 2. The changing magnetic field will cause the ceramic induction heating element 31 to undergo electromagnetic coupling and generate an induced current. The ceramic induction heating element 31 transfers the heat generated by the induced current to the herbal product 9, thereby heating and atomizing the herbal product 9.

[0082] Furthermore, by using a ceramic induction heating element 31 doped with a non-magnetic conductive metal material 300 and a magnetic material 400, compared to a heating element that is not electromagnetic, in the heating non-combustible device 10 of this application embodiment, when the induction coil 4 generates a changing magnetic field due to the changing current generated by the energization, the ceramic induction heating element 31 can also rapidly form a stronger current eddy current within itself due to electromagnetic induction, thereby increasing the heat generated by the ceramic induction heating element 31 per unit time, heating the atomized herbal product 9 more quickly and efficiently, and improving the user's inhalation experience and inhalation taste.

[0083] In some other embodiments, such as Figure 12As shown, the ceramic induction heating element 31 can also be made of a mixture of semiconductor material 500, electrically insulating ceramic material 100, and magnetic material 400. Specifically, the semiconductor material 500 can include any one of carbon, silicon, germanium, gallium arsenide, indium phosphide, silicon carbide, and gallium nitride, without limitation here. The magnetic material 400 can include any one of neodymium iron boron, samarium cobalt, iron, nickel, cobalt, and their alloys, wherein the aforementioned "alloy" can be an iron-nickel alloy, an iron-cobalt alloy, a nickel-cobalt alloy, or an iron-nickel-cobalt alloy, without limitation here. Thus, when the ceramic induction heating element 31 is doped with the aforementioned semiconductor material 500 and magnetic material 400, the ceramic induction heating element 31 becomes electromagnetic. In this way, when the induction coil 4 generates a changing current due to energization, the induction coil 4 generates a changing magnetic field in the area formed by its own periphery and the surrounding sleeve 2. The ceramic induction heating element 31 can sense the changing magnetic field generated by the induction coil 4 and generate an induced current, and transfer the heat generated by the induced current to the herbal product 9, thereby heating and atomizing the herbal product 9.

[0084] Furthermore, in some embodiments, the temperature sensing element 33 can be a non-magnetic temperature sensor. The aforementioned "non-magnetic temperature sensor" refers to a temperature sensor that does not exhibit magnetic properties in an external magnetic field; that is, a non-magnetic temperature sensor will not generate an induced current and be electrically heated in a changing magnetic field.

[0085] Since the temperature sensing element 33 is a non-magnetic temperature sensor, it will not generate an induced current and be electrically heated in the changing magnetic field produced by the induction coil 4. That is, the temperature sensing element 33 itself will not generate heat, thus avoiding the temperature sensing element 33's own heat generation from affecting the accuracy of the temperature measurement result. In other words, using a non-magnetic temperature sensor as the temperature sensing element 33 in this embodiment can improve the accuracy of the temperature measurement result.

[0086] In this embodiment, the aforementioned non-magnetic temperature sensor can be a platinum resistance temperature sensor or a thermocouple temperature sensor. The platinum resistance temperature sensor is made of platinum metal, which is a non-magnetic material. The thermocouple temperature sensor works as follows: two conductors of different materials form a closed circuit, constituting a thermocouple. When a temperature gradient exists due to the temperature difference between the two ends of the thermocouple, current flows through the closed circuit, creating a thermoelectric potential between the two ends. Therefore, once the material composition of the thermocouple is determined, the magnitude of the thermoelectric potential is independent of the changing magnetic field generated by the induction coil 4, the length of the thermocouple, and its diameter; it only depends on the temperature difference between the two ends of the thermocouple. Thus, the thermocouple temperature sensor will not generate heat itself within the changing magnetic field generated by the induction coil 4, thereby preventing the thermocouple temperature sensor from generating heat that could affect the accuracy of the temperature measurement results.

[0087] Of course, the non-magnetic temperature sensor in this embodiment may also include other temperature sensors that do not generate induced current and are electrically heated in a changing magnetic field; no specific limitation is made here.

[0088] Furthermore, in some embodiments, the temperature sensing element 33 can also be a magnetic temperature sensor. In this embodiment, the aforementioned magnetic temperature sensor can be a magnetoresistive temperature sensor or a ferromagnetic temperature sensor. Of course, the magnetic temperature sensor in this embodiment can also include other magnetic temperature sensors, and specific details are not limited here.

[0089] like Figures 2 to 8 As shown, in some optional embodiments of this utility model, the heating non-combustible device 10 further includes a first fixing member 32 installed inside the outer casing 1 and located outside the heating chamber 21. One end of the ceramic induction heating element 31 away from the opening 11 is fixedly connected to the first fixing member 32, and the remaining portion of the ceramic induction heating element 31 extends into the heating chamber 21. The ceramic induction heating element 31 can be as follows: Figures 3 to 8 The sheet-like shape shown in the embodiment can also be as follows: Figure 2 In the illustrated embodiment, the rod-shaped ceramic induction heating element 31 is used to be inserted into the herbal product 9, wherein the material of the first fixing element 32 is a non-electromagnetic induction material.

[0090] Specifically, such as Figures 2 to 7 As shown, the lower end of the ceramic induction heating element 31 is fixedly connected to the first fixing member 32, and the rest of the ceramic induction heating element 31 extends into the heating chamber 21. Thus, by fixing the lower end of the ceramic induction heating element 31 to the first fixing member 32, the ceramic induction heating element 31 is fixed inside the sleeve 2. In this way, the rest of the ceramic induction heating element 31 can be directly inserted into the tobacco product 9 located in the heating chamber 21 and fully contact the tobacco product 9, thereby increasing the contact area between the ceramic induction heating element 31 and the tobacco product 9, i.e., increasing the heating area of ​​the ceramic induction heating element 31, resulting in more complete atomization of the tobacco product 9.

[0091] It should be noted that, as Figures 3 to 8 As shown, the upper end of the ceramic induction heating element 31 can be a pointed structure. In this way, the pointed structure of the ceramic induction heating element 31 can be inserted into the herbal product 9 more quickly and easily, and the ceramic induction heating element 31 is not easy to break due to insertion.

[0092] Of course, in other embodiments, the ceramic induction heating element 31 can also be other structures, such as a spiral structure (not shown). The spiral ceramic induction heating element 31 can be arranged around the inner peripheral wall of the sleeve 2. When the herbal product 9 is inserted into the heating chamber 21 of the sleeve 2, the spiral ceramic induction heating element 31 contacts the outer surface of the herbal product 9. In this way, the ceramic induction heating element 31 can transfer the heat generated by its own induced current to the herbal product 9, thereby heating and atomizing the herbal product 9.

[0093] Furthermore, when the temperature sensing element 33 is a magnetic temperature sensor, since a magnetic temperature sensor generates an induced current in a changing magnetic field and is electrically heated, the temperature sensing element 33 must be placed outside the magnetic field generated by the induction coil 4, or in a location with the weakest possible magnetic field strength. For example, the temperature sensing element 33 can be placed outside the space surrounded by the induction coil 4. Correspondingly, the temperature sensing element 33 will not generate an induced current when the magnetic field strength is zero, thus preventing the generation of heat that could lead to inaccurate measurements. Alternatively, the induced current generated by the temperature sensing element 33 in a weak magnetic field region is small, and the heat generated by this induced current is also small, even negligible. Therefore, the influence of the heat generated by the temperature sensing element 33 itself on the accuracy of the temperature measurement results can be reduced.

[0094] Specifically, when the temperature sensing element 33 is a magnetic temperature sensor, the temperature sensing element 33 can be configured in the following ways:

[0095] The first setup method is as follows: Figures 2 to 4 As shown, the temperature measuring element 33 can be mounted on the first fixing element 32, and the temperature measuring element 33 is located outside the space surrounding the induction coil 4.

[0096] In the first setup method, such as Figure 2 and Figure 3 As shown, the temperature measuring element 33 can be fixedly connected to the first fixing member 32, and the temperature measuring element 33 is exposed on the upper end surface of the first fixing member 32. At this time, the part of the temperature measuring element 33 exposed on the upper end surface of the first fixing member 32 can directly contact the lower end surface of the ceramic induction heating element 31. In this way, the temperature measuring element 33 can directly measure the temperature of the ceramic induction heating element 31. That is, during the temperature measurement process, the temperature measuring element 33 can detect the heating temperature of the ceramic induction heating element 31 at zero distance, thereby enabling rapid and accurate detection of the heating temperature of the ceramic induction heating element 31, which in turn facilitates the control element 5 to accurately control the temperature of the ceramic induction heating element 31.

[0097] like Figure 4As shown, the temperature measuring element 33 can also be embedded in the first fixing element 32. In this case, since the temperature measuring element 33 is not in direct contact with the ceramic induction heating element 31, there will be a deviation between the temperature detected by the temperature measuring element 33 and the actual heating temperature of the ceramic induction heating element 31. In this embodiment, in order to enable the temperature measuring element 33 to accurately detect the actual heating temperature of the ceramic induction heating element 31, temperature compensation can be performed on the temperature measuring element 33. For example, a compensation temperature can be set first, and then the value obtained by adding the temperature detected by the temperature measuring element 33 to the compensation temperature can be used as the actual heating temperature of the ceramic induction heating element 31. In this way, the actual heating temperature of the ceramic induction heating element 31 can be obtained quickly and accurately, which is beneficial for the control element 5 to accurately control the temperature of the ceramic induction heating element 31.

[0098] Of course, in the first setting, the temperature measuring element 33 can also be fixedly connected to the side wall or bottom wall of the first fixing element 32 (not shown), and the specifics are not limited here.

[0099] It should be noted that in this embodiment, since the material of the first fixing member 32 is a non-electromagnetic induction material, no induced current will be generated on the first fixing member 32, that is, the first fixing member 32 is a non-energized component. Therefore, when the temperature measuring element 33 is mounted on the first fixing member 32, the temperature measurement result of the temperature measuring element 33 will not be affected by the first fixing member 32, thereby further ensuring the accuracy of the temperature measurement result.

[0100] In this embodiment, the first fixing member 32 can be made of any one of silicon carbide, ceramic, quartz, and glass. Of course, in other embodiments, the first fixing member 32 can also be made of other non-electromagnetic induction materials, and this is not limited here.

[0101] The second setup method is as follows: Figure 5 As shown, the temperature measuring element 33 can be installed on the inner peripheral wall of the end of the sleeve 2 away from the opening 11, and the temperature measuring element 33 is located outside the space surrounding the induction coil 4. It should be noted that the end of the sleeve 2 away from the opening 11 is the lower end of the sleeve 2, that is, the temperature measuring element 33 is located on the inner peripheral wall of the lower end of the sleeve 2.

[0102] In this configuration, since the temperature sensing element 33 is not in direct contact with the ceramic induction heating element 31, temperature compensation is also required for the temperature sensing element 33 in this embodiment to accurately obtain the heating temperature of the ceramic induction heating element 31. The details of temperature compensation can be found in [reference needed]. Figure 4 The description of the embodiments is omitted here.

[0103] The third setup method is as follows: Figure 6As shown, the temperature measuring element 33 can also be installed on the outer peripheral wall of the end of the sleeve 2 away from the opening 11, and the temperature measuring element 33 is located outside the space surrounded by the induction coil 4, that is, the temperature measuring element 33 is located on the outer peripheral wall of the lower end of the sleeve 2.

[0104] In this configuration, since the temperature measuring element 33 is not in direct contact with the ceramic induction heating element 31, temperature compensation is also required for the temperature measuring element 33 in this embodiment. The details of temperature compensation will not be elaborated here.

[0105] It should be noted that in the above embodiments where temperature compensation of the temperature measuring element 33 is required, the compensation temperature can be set according to factors such as the distance between the temperature measuring element 33 and the ceramic induction heating element 31, the obstruction between the temperature measuring element 33 and the ceramic induction heating element 31, and the thermal conductivity of the obstruction, and is not limited here.

[0106] Furthermore, in this embodiment, when the temperature sensing element 33 is a non-magnetic temperature sensor, the temperature sensing element 33 can be disposed at any position within the housing 1. For example, such as Figure 7 As shown, the temperature measuring element 33 can be embedded in the ceramic induction heating element 31; or, the temperature measuring element 33 can also be mounted on the first fixing element 32 (see reference). Figures 2 to 4 Alternatively, the temperature measuring element 33 can also be installed on the inner circumferential wall of the end of the sleeve 2 away from the opening 11 (see reference). Figure 6 Alternatively, the temperature measuring element 33 can also be installed on the outer peripheral wall of the end of the sleeve 2 away from the opening 11 (see reference). Figure 7 Preferably, the temperature measuring element 33 is mounted on any part of the ceramic induction heating element 31.

[0107] Furthermore, combined Figure 8 and Figure 9 As shown, the heated non-combustible device 10 also includes a base 34, which is detachably connected to the end of the sleeve 2 away from the opening 11. A first fixing member 32 is mounted on the base 34. The inner wall of the sleeve 2 is provided with a snap-fit ​​portion 22 at the end away from the opening 11. The outer wall of the base 34 is provided with an insertion groove 341 and an arc-shaped groove 342. The insertion groove 341 is arranged along the axial direction of the sleeve 2 and one end of the insertion groove 341 extends to the end face of the base 34 away from the opening 11. The arc-shaped groove 342 is arranged along the circumference of the base 34 and one end of the arc-shaped groove 342 is connected to the other end of the insertion groove 341. The other end of the arc-shaped groove 342 is bent toward the end face of the base 34 away from the opening 11. When the snap-fit ​​part 22 is located in the arc-shaped groove 342, the base 34 and the sleeve 2 are snapped together; when the snap-fit ​​part 22 is located in the insertion groove 341, the base 34 and the sleeve 2 are disengaged, and the user can remove the base 34 from the sleeve 2.

[0108] It should be noted that, as Figure 8 and Figure 9 As shown, one end of the insertion groove 341 is the lower end of the insertion groove 341, and the other end of the insertion groove 341 is the upper end of the insertion groove 341. The end face of the base 34 away from the opening 11 is the lower end face of the base 34. That is, the lower end of the insertion groove 341 passes through the lower end face of the base 34. One end of the arc-shaped groove 342 is connected to the upper end of the insertion groove 341, and the other end of the arc-shaped groove 342 is bent towards the lower end face of the base 34.

[0109] Furthermore, in this embodiment, as Figures 2 to 8 As shown, the heated non-combustible device 10 also includes a first positive electrode 35 and a first negative electrode 36. The first positive electrode 35 and the first negative electrode 36 are spaced apart on the end of the base 34 away from the opening 11, and the first positive electrode 35 and the first negative electrode 36 are electrically connected to the temperature measuring element 33. A second positive electrode 6 and a second negative electrode 7 are provided inside the outer casing 1. One end of the second positive electrode 6 and the second negative electrode 7 are electrically connected to the control element 5, the other end of the second positive electrode 6 is electrically connected to the first positive electrode 35, and the other end of the second negative electrode 7 is electrically connected to the first negative electrode 36. In specific implementations, the first positive electrode 35 or the second positive electrode 6 is an elastic electrode, and the first negative electrode 36 or the second negative electrode 7 is an elastic electrode. Specifically, there are four combinations: the first combination is that both the first positive electrode 35 and the first negative electrode 36 are elastic electrodes; the second combination is that both the second positive electrode 6 and the second negative electrode 7 are elastic electrodes; the third combination is that both the first positive electrode 35 and the second negative electrode 7 are elastic electrodes; and the fourth combination is that both the second positive electrode 6 and the first negative electrode 36 are elastic electrodes.

[0110] Based on the above structural design, such as Figures 2 to 4 As shown, when the temperature measuring element 33 is mounted on the first fixing element 32, the ceramic induction heating element 31, the first fixing element 32, the temperature measuring element 33, the base 34, the first positive electrode 35, and the first negative electrode 36 can be combined to form a complete heating core assembly 3. In this way, the user can easily insert the heating core assembly 3 into the sleeve 2 through the opening 11, or easily remove the heating core assembly 3 from the opening 11. Specifically, when components such as the ceramic induction heating element 31 and the temperature measuring element 33 are damaged or need to be replaced for other reasons, the heating core assembly 3 can be disassembled and replaced to achieve the purpose of replacing components such as the ceramic induction heating element 31 and the temperature measuring element 33. The whole process is very convenient.

[0111] Furthermore, since the heating core assembly 3 is exposed to the outside after being disassembled, users can more easily clean it. For example, they can remove impurities adhering to the ceramic induction heating element 31, such as dust or residues left after the herbal product 9 is heated and atomized. Also, since removing the heating core assembly 3 effectively empties the heating chamber 21, users can avoid obstructions from the ceramic induction heating element 31, the first fixing member 32, and other components when cleaning the heating chamber 21, thus achieving convenient cleaning of the heating chamber 21.

[0112] Optionally, in this embodiment, the detachable connection between the base 34 and the sleeve 2 can be a snap-fit ​​connection, or other detachable connection methods, as long as they meet the usage requirements, and no specific limitation is made here.

[0113] Combination Figures 2 to 9 As shown, the arc-shaped groove 342 includes a transition groove 3421 and a retaining groove 3422. One end of the transition groove 3421 is connected to the insertion groove 341. The retaining groove 3422 is arranged along the axial direction of the base 34 and one end of the retaining groove 3422 is connected to the other end of the transition groove 3421. The other end of the retaining groove 3422 extends in a direction away from the opening 11. Along the axial direction of the base 34, the length of the insertion groove 341 is greater than the length of the retaining groove 3422. When the locking part 22 moves from the insertion groove 341 to the transition groove 3421, the base 34 compresses each elastic electrode, and the base 34 and the sleeve 2 lock together. When the locking part 22 continues to move to the end of the transition groove 3421 away from the insertion groove 341, under the reaction force of the compression elastic force generated by the elastic deformation of each elastic electrode, the base 34 moves towards the opening 11, so that the locking part 22 moves from the transition groove 3421 into the locking groove 3422. At this time, the elastic electrode returns to its original shape, and the base 34 and the sleeve 2 lock together.

[0114] It should be noted that the above-mentioned elastic electrodes can be any of the above combinations. For example, when the second positive electrode 6 and the second negative electrode 7 are elastic electrodes, when the snap-fit ​​part 22 on the sleeve 2 moves from the insertion groove 341 to the transition groove 3421, the base 34 will compress the second positive electrode 6 and the second negative electrode 7, and the base 34 and the sleeve 2 will snap together. At this time, the base 34 and the sleeve 2 cannot move relative to each other along the axial direction of the sleeve 2, but the base 34 and the sleeve 2 can rotate relative to each other along the circumferential direction of the sleeve 2. Thus, when the base 34 or the sleeve 2 is rotated, the locking part 22 on the sleeve 2 will continue to move to the end of the transition groove 3421 away from the insertion groove 341. At this time, under the reaction force of the compressive elastic force generated by the elastic deformation of the second positive electrode 6 and the second negative electrode 7, the base 34 will also move towards the opening 11, so that the locking part 22 moves from the transition groove 3421 into the locking groove 3422, thereby locking the base 34 and the sleeve 2 together, that is, the base 34 and the sleeve 2 cannot rotate relative to each other along the circumference of the sleeve 2. In this embodiment, the rotation of the base 34 can be achieved by rotating the entire heating core assembly 3, and the rotation of the sleeve 2 can be achieved by rotating the outer shell 1.

[0115] Based on the above structural design, when disassembling the heating core assembly 3, the user first needs to press down on the base 34. Under the downward pressure, the elastic electrode undergoes compression deformation, and the base 34 moves downward. Simultaneously, the locking part 22 slides upward relative to the base 34 within the locking groove 3422 until it slides from the locking groove 3422 into the transition groove 3421. At this point, the locking part 22 and the locking groove 3422 are unlocked, while the base 34 and the sleeve 2 remain locked together. Then, the base 34 or the sleeve 2 is rotated to allow the locking part 22 to slide towards the insertion groove 341 within the transition groove 3421 until it slides from the transition groove 3421 into the insertion groove 341. At this point, the base 34 and the sleeve 2 are no longer locked together, allowing the user to pull out the heating core assembly 3 along the opening 11 of the outer casing 1, thus completing the disassembly of the heating core assembly 3. When installing the heating core assembly 3, align the insertion groove 341 on the base 34 with the snap-fit ​​part 22, and then insert the entire heating core assembly 3 into the sleeve 2 from the opening 11 so that the snap-fit ​​part 22 slides into the insertion groove 341 and slides along the insertion groove 341 until the snap-fit ​​part 22 touches the top wall of the insertion groove 341. At this time, each elastic electrode undergoes compression deformation, and the snap-fit ​​part 22 is located at the connection between the insertion groove 341 and the transition groove 3421. Then rotate the base 34 or the sleeve 2 so that the locking part 22 slides into the transition groove 3421 until the locking part 22 slides to the end of the transition groove 3421 away from the insertion groove 341. The user removes the force applied to the base 34 or the sleeve 2. At this time, under the action of the reaction force of the compressive elastic force generated by the elastic deformation of each elastic electrode, the base 34 moves relative to the locking part 22 toward the opening 11, so that the locking part 22 slides from the transition groove 3421 into the locking groove 3422, thereby locking the base 34 and the sleeve 2 together. In this way, the installation of the heating core assembly 3 can be completed.

[0116] Furthermore, such as Figure 8 As shown, in some optional embodiments, a slot 343 is provided on the end face of the base 34 near the opening 11, and the first fastener 32 is inserted into the slot 343.

[0117] Furthermore, combined Figures 2 to 7 As shown, the inner wall of the slot 343 is provided with a buckle 344, and the first fixing member 32 is provided with a buckle groove 321 corresponding to the buckle 344. The buckle 344 and the buckle groove 321 are engaged with each other so that the first fixing member 32 is fixed in the slot 343, thereby improving the reliability of the connection between the first fixing member 32 and the base 34.

[0118] Optionally, in this embodiment, the first fixing member 32 and the ceramic induction heating element 31 are sintered together, which can improve the reliability of the connection between the first fixing member 32 and the ceramic induction heating element 31. Of course, the connection method between the first fixing member 32 and the ceramic induction heating element 31 can also be bonding or snap-fitting, etc., as long as it meets the usage requirements, and no specific limitation is made here.

[0119] In some other optional embodiments of this utility model, such as Figures 13 to 16 As shown, the ceramic induction heating element 31 is in the shape of a hollow tube. A second fixing element 37, which is also in the shape of a hollow tube, is connected to the end of the ceramic induction heating element 31 away from the opening 11. The second fixing element 37 is located outside the heating chamber 21. The ceramic induction heating element 31 and the second fixing element 37 are connected to each other and installed in the sleeve 2 and are tightly fitted to the inner peripheral wall of the sleeve 2. The opening 11 is connected to the internal cavity of the ceramic induction heating element 31 and the second fixing element 37. The material of the second fixing element 37 is a non-electromagnetic induction material.

[0120] In this embodiment, since the material of the second fastener 37 is also a non-electromagnetic induction material, the second fastener 37 can also be made of any one of silicon carbide, ceramic, quartz, and glass. Furthermore, the second fastener 37 can be made of the same non-electromagnetic induction material as the first fastener 32, or it can be made of a different non-electromagnetic induction material; no specific limitation is made here.

[0121] Furthermore, when the temperature sensing element 33 is a magnetic temperature sensor, since a magnetic temperature sensor generates an induced current in a changing magnetic field and is electrically heated, the temperature sensing element 33 must be placed outside the magnetic field generated by the induction coil 4, or in a location with the weakest possible magnetic field strength. For example, the temperature sensing element 33 can be placed outside the space surrounded by the induction coil 4. Correspondingly, the temperature sensing element 33 will not generate an induced current when the magnetic field strength is zero, thus preventing the generation of heat that could lead to inaccurate measurements. Alternatively, the induced current generated by the temperature sensing element 33 in a weak magnetic field region is small, and the heat generated by this induced current is also small, even negligible. Therefore, the influence of the heat generated by the temperature sensing element 33 itself on the accuracy of the temperature measurement results can be reduced.

[0122] Specifically, in some embodiments, when the temperature sensing element 33 is a magnetic temperature sensor, such as Figures 14 to 16 As shown, the temperature measuring element 33 can be installed on the outer peripheral wall of the second fixing member 37, and the temperature measuring element 33 is located outside the space surrounding the induction coil 4. The effect it achieves can be referred to Figure 4 The specific details of the embodiments will not be repeated here.

[0123] In other embodiments, when the temperature sensing element 33 is a magnetic temperature sensor, the temperature sensing element 33 can also be mounted on the inner or outer peripheral wall of the sleeve 2 away from the opening 11 (not shown), and the temperature sensing element 33 is located outside the space surrounding the induction coil 4. The effect it can achieve can be referred to Figure 5 and Figure 6 The specific details of the embodiments are not repeated here.

[0124] In other embodiments, when the temperature sensing element 33 is a non-magnetic temperature sensor, the temperature sensing element 33 can be disposed at any position within the heating non-combustible device 10. For example, such as Figure 13 As shown, the temperature measuring element 33 can be mounted on the ceramic induction heating element 31; or, the temperature measuring element 33 can also be mounted on the outer peripheral wall of the second fixing element 37 (see reference). Figures 14 to 16 Alternatively, the temperature measuring element 33 can also be installed on the inner or outer peripheral wall of the sleeve 2 at the end away from the opening 11 (not shown).

[0125] Based on the above structural design, when the ceramic induction heating element 31 heats the herbal product 9, since the herbal product 9 is inserted into the internal cavity of the ceramic induction heating element 31, the ceramic induction heating element 31 can heat the herbal product 9 by means of peripheral heating. That is, the heat generated by the ceramic induction heating element 31 is conducted from the periphery of the herbal product 9 to the center, thereby heating and atomizing the herbal product 9 and generating an aerosol that can be inhaled by the user.

[0126] In some optional embodiments of this utility model, such as Figures 2 to 8 , Figures 13 to 15 As shown, a heat insulation layer 8 is provided between the inner wall of the outer shell 1 and the induction coil 4. The heat insulation layer 8 is used to block the heat generated by the ceramic induction heating element 31 from being conducted to the outer shell 1, thereby preventing the outer shell 1 from becoming too hot to touch and reducing heat loss, so that more heat can be used to heat the atomized herbal product 9, thereby reducing the energy consumption of the heating non-combustible device 10.

[0127] Optionally, in this embodiment, the heat insulation layer 8 can be disposed around the outer periphery of the induction coil 4, or the heat insulation layer 8 can also be disposed around the inner wall of the outer casing 1. In specific implementation, by covering the outer periphery of the induction coil 4 with the heat insulation layer 8, a better heat insulation effect can be achieved.

[0128] Optionally, in this embodiment, the heat insulation layer 8 is made of any one of aerogel, asbestos, ceramic and quartz materials.

[0129] It should be noted that other contents of the heating non-combustible device 10 disclosed in this utility model can be found in the prior art, and will not be repeated here.

[0130] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
