Description

Technical Field

[0001] This application relates to the field of aerosol generation equipment technology, specifically to a heating component and a heating non-combustible device. Background Technology

[0002] The counting function of heated non-combustible devices largely relies on the detection mechanism of airflow sensors to detect changes in suction negative pressure. Specifically, when the user suctions, the airflow changes in the device's internal air passages generate a negative pressure signal, triggering the airflow sensor to generate a detection signal to accumulate the number of suctions.

[0003] To achieve real-time detection, the internal air duct of the device needs to be in constant contact with the airflow sensor. However, during long-term use, aerosol residues (such as condensate or aerosol matrix components) can easily adhere to the airflow sensor and gradually form grease buildup. This buildup can contaminate the sensing unit of the airflow sensor, causing the counting function of the heated non-combustible device to fail and affecting the user experience. Utility Model Content

[0004] In order to reduce the risk of failure of the counting function of the heating non-combustible device, this application provides a heating component and a heating non-combustible device.

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

[0006] A heating element has a heating chamber and a heating air passage. The heating chamber is used to contain at least a portion of the aerosol-generating article, and the heating air passage connects the heating chamber to the external environment to form an airflow path. The heating element is used to heat the air flowing through the heating air passage to heat the aerosol-generating article using hot air.

[0007] A temperature sensing module is provided, which is fixed to the outer surface of the heating element corresponding to the heating air passage. The temperature sensing module is used to detect the temperature fluctuation of the heating element caused by the suction action.

[0008] In one embodiment, the heating chamber has a product insertion port on one side for inserting the aerosol-generated product. The sidewall and bottomwall of the heating chamber are provided with protrusions. Multiple protrusions are spaced apart along the circumference of the heating chamber. The heating air passage is formed between adjacent protrusions and communicates with the product insertion port.

[0009] In one embodiment, the protrusion has a heat-conducting surface for contacting the aerosol-generating article inserted into the heating chamber to transfer heat to the aerosol-generating article.

[0010] In one embodiment, the heat conduction surface is a plane.

[0011] In one embodiment, the heating chamber has a heat radiation surface for radiative heating of the aerosol-generated product.

[0012] In one embodiment, the heating element includes a cup body and a heating circuit, wherein the heating circuit is disposed at the bottom of the cup body for heating the cup body.

[0013] In one embodiment, the protrusion includes a first part and a second part integrally formed with the cup body. The first part is disposed on the side wall of the heating cavity and is disposed in a direction parallel to the axial direction of the heating cavity. The second part is disposed on the bottom wall of the heating cavity and is disposed in the radial direction of the heating cavity.

[0014] In one embodiment, the temperature sensing module is a thermocouple or an NTC temperature sensor.

[0015] In one embodiment, the thickness of the airway wall between the temperature sensing module and the corresponding heating airway is no greater than 1 mm.

[0016] According to a second aspect, one embodiment provides a heating non-combustible device, comprising:

[0017] The heating assembly described in any of the above embodiments;

[0018] A power supply component is electrically connected to the heating element and the temperature sensing module to supply power to the heating element and the temperature sensing module; the power supply component includes a counting unit electrically connected to the temperature sensing module to accumulate the number of suctions based on the detection signal of the temperature sensing module.

[0019] The heating component of the heating non-combustible device according to the above embodiment has a heating air passage in the heating element and a temperature sensing module is provided on the outer surface of the heating element corresponding to the heating air passage. The heating element can heat and generate hot air, and use the hot air to heat the aerosol to generate the product through convection heating.

[0020] During suction, the suction action causes airflow in the heating air passage. As external air is replenished into the heating air passage, temperature fluctuations occur in the part of the heating element located around the heating air passage. The temperature sensing module can detect these temperature fluctuations and convert them into electrical signals. The counting unit in the heated non-combustible device can accumulate the number of suction ports based on the output electrical signals.

[0021] Since the temperature sensing module is located outside the heating element, it is not easily affected by scale buildup, which helps reduce the risk of the counting function of the heating non-combustible device failing. Attached Figure Description

[0030] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0031] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0032] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0033] Some heated tobacco products (HTMs) have a counting function for user management. This counting function typically relies on an airflow sensor detecting negative pressure changes caused by suction. This requires the internal air passages and the airflow sensor to be constantly connected. This makes it easy for aerosol residues (such as condensate or aerosol matrix components) to adhere to the airflow sensor after suction, forming grease buildup and contaminating the sensor's sensing unit. Prolonged use can easily cause the airflow sensor to malfunction, resulting in the HTM's counting function failing and impacting the user experience.

[0034] In this embodiment, an aerosol-generated article 400 is heated by a heating element 100 with a heating airway 120. Based on the phenomenon that airflow within the heating airway 120 during suction causes temperature fluctuations, a temperature sensing module 200 is installed outside the heating element 100 corresponding to the heating airway 120. This module detects the temperature fluctuations caused by the suction action, thus achieving a novel counting function. Because the temperature sensing module 200 is located outside the heating element 100 and is independent of the airway in the heated non-combustible device, it is less susceptible to scale buildup caused by aerosol residues, helping to reduce the risk of counting function failure and extending the device's lifespan.

[0035] Embodiments of the heating component of the heating non-combustible device in this application:

[0036] In one embodiment, please refer to Figures 1-3 The heating component of the non-combustible heating device includes a heating element 100 and a temperature sensing module 200.

[0037] The heating element 100 can be understood as a component in a heated non-combustible device used to generate heat to heat the aerosol to form the product 400. Please refer to [reference needed]. Figure 1 and Figure 2The heating element 100 has a heating chamber 110 and a heating air passage 120; the heating chamber 110 is used to accommodate at least a portion of the aerosol generating article 400, such as to accommodate the matrix segment of the aerosol generating article 400 for generating aerosols; the heating air passage 120 connects the heating chamber 110 to the external environment to form an air flow path; the heating element 100 can be used to heat the air flowing through the heating air passage 120 to heat the aerosol generating article 400 with hot air.

[0038] During suction, the air in the heated airway 120 will flow due to the negative pressure, resulting in temperature fluctuations. By detecting these temperature fluctuations, it can be determined whether a suction action has occurred, thus realizing the counting function.

[0039] The temperature sensing module 200 can be understood as a component used to detect temperature fluctuations caused by the suction action; for example, the temperature sensing module 200 can be a thermocouple, an NTC temperature sensor, or other sensors that meet the design and usage requirements.

[0040] To prevent aerosol residue from accumulating as oil on the airflow sensor after use, the temperature sensing module 200 can be positioned outside the heating element 100. Furthermore, to improve the accuracy of the temperature sensing module 200 in identifying temperature fluctuations within the heating air passage 120 and reduce the risk of misjudgment, the temperature sensing module 200 can be positioned as close as possible to the heating air passage 120; for example, the temperature sensing module 200 can be fixed to the outer surface of the heating element 100 corresponding to the heating air passage 120.

[0041] In one embodiment, please refer to Figure 1 The temperature sensing module 200 can be adhered and fixed to the outer surface of the heating element 100, such as the outer peripheral wall of the heating element 100, so that the temperature sensing module 200 is in direct contact with the outer wall of the heating air passage 120. The temperature sensing module 200 can generate a pulse signal corresponding to a single suction by detecting the temperature fluctuation caused by the air flow in the heating air passage 120 due to the suction action. After the pulse signal is sent to the counting unit in the heating non-combustion device, the counting unit can accumulate the number of suctions based on the pulse signal.

[0042] Those skilled in the art should understand that the method of fixing the temperature sensing module 200 is not limited. For example, the temperature sensing module 200 can also be fixed to the outside of the heating element 100 by a fixing structure. The fixing structure can be fasteners such as screws and bolts, or limiting components such as straps and clamps. It can also be a locking hole or slot provided on the outer surface of the heating element 100 to allow the temperature sensing module 200 to be locked to the outside of the heating element 100. The fixing position of the temperature sensing module 200 is also not limited. For example, it can also be fixed to the end face of the heating element 100.

[0043] It is understood that the thickness of the airway wall between the temperature sensing module 200 and the heating airway 120 will affect the detection and recognition of the temperature sensing module 200. Therefore, in one embodiment, the thickness of the airway wall between the temperature sensing module 200 and the corresponding heating airway 120 can be set to no more than 1 mm, for example, 0.5 mm to 1 mm, in order to reduce the risk of misjudgment.

[0044] In other embodiments, based on the type of temperature sensing module 200 and the material of heating element 100, the thickness of the airway wall between temperature sensing module 200 and the corresponding heating airway 120 can also be set to be greater than 1 mm, such as 1.2 mm, 1.5 mm, 2 mm, etc., or set to be less than 0.5 mm, such as 0.4 mm, 0.2 mm, etc., so that temperature sensing module 200 can detect and identify the temperature fluctuation caused by the suction action.

[0045] In some further embodiments, at least two temperature sensing modules 200 can be provided to perform temperature detection separately, thereby forming a multi-point detection anti-false alarm mechanism. For example, three sets of temperature sensing modules 200 can be provided at different locations on the heating element 100, such as three sets of temperature sensing modules 200 evenly distributed along the circumference of the outer surface of the heating element 100 to form a detection array. Only when any two sets of temperature sensing modules 200 simultaneously detect a temperature fluctuation is it determined to be a valid suction action and counted. In different embodiments, the number and relative positions of the temperature sensing modules 200 are not limited, as long as they help to form an anti-false alarm mechanism and reduce the risk of false alarms.

[0046] Furthermore, it can be understood that the structure and shape of the heating element 100 are not limited, as long as it has a heating cavity 110 and a heating air passage 120 communicating with the heating cavity 110, and is capable of heating the air flowing through the heating air passage 120.

[0047] For example, the heating element 100 can be a tubular or cup-shaped structure, and its inner cavity can serve as a heating chamber 110. One side of the heating chamber 110 can have a product insertion port 111 for inserting the aerosol-generated product 400. The heating air passage 120 can be disposed on the surface of the heating chamber 110 wall or inside the heating chamber 110 wall, forming an airflow path that connects the heating chamber 110 to the external environment. The heating element 100 can have a heating portion based on Joule heating, eddy current heating, or other heating methods. The heating portion can be disposed at any suitable location within the heating element 100, as long as it meets the heating requirements.

[0048] In one embodiment, please refer to Figure 2 and Figure 3The heating element 100 may include a cup body 130 and a heating circuit 140. The heating circuit 140 may be disposed at the bottom of the cup body 130 for heating the cup body 130. The heating cavity 110 and the heating air passage 120 are both disposed in the cup body 130. The cup cavity of the cup body 130 serves as the heating cavity 110, and the opening at one end of the cup cavity serves as the product insertion port 111. The cup body 130 can transfer the heat generated by the heating circuit 140 to the heating air passage 120, and then to the heating cavity 110, to heat the aerosol-generated product 400 in the heating cavity 110.

[0049] In a further embodiment, please refer to Figure 1 and Figure 2 The heating chamber 110 may have protrusions 150 on its sidewalls and bottomwalls. Multiple protrusions 150 are spaced apart circumferentially around the heating chamber 110, forming heating air passages 120 between adjacent protrusions 150. These heating air passages 120 are connected to the product insertion port 111. During suction, the suction action creates a negative pressure within the heating chamber 110, allowing air from outside the cup body 130 to enter the heating air passages 120 through the product insertion port 111. Since the newly entering air is at a lower temperature, it causes temperature fluctuations around the heating air passages 120, which are then detected and identified by the temperature sensing module 200.

[0050] In another embodiment, only one protrusion 150 may be provided, so that a heating air passage 120 is formed around the protrusion 150. In other embodiments, the heating air passage 120 may also be formed by slotting or opening in the sidewall and bottomwall of the heating cavity 110, or by slotting or opening in one of the sidewall and bottomwall of the heating cavity 110 and providing multiple protrusions 150 at intervals on the other to cooperate in forming the heating air passage 120. In short, the specific arrangement of the heating air passage 120 is not limited, as long as it meets the design and usage requirements.

[0051] In some embodiments, please refer to Figure 1 and Figure 2 The protrusion 150 may have a heat-conducting surface 153 for contacting the aerosol generating article 400 inserted into the heating chamber 110, so as to transfer heat to the aerosol generating article 400 through contact, forming a composite heating method that combines heating and convection, which helps to improve heating efficiency and heating stability. The heat-conducting surface 153 can be a flat surface for easy processing and shaping; it can also be an arc surface, for example, an arc surface that fits against the outer surface of the cylindrical aerosol generating article 400 to improve heat transfer efficiency. Of course, the heat-conducting surface 153 can also be designed in other shapes.

[0052] In some embodiments, the heating chamber 110 also has a heat radiation surface 160 for radiative heating of the aerosol-generated article 400. It is understood that all surfaces in the heating chamber 110 except for the heat conduction surface 153 can serve as heat radiation surfaces 160, and the heat radiation surface 160 can also be provided with additional layers such as coatings or platings that enhance the heat radiation effect to improve the heat radiation efficiency.

[0053] The arrangement of the heat conduction surface 153 and the heat radiation surface 160 enables the heating element 100 to form a multi-dimensional heating structure integrating heat conduction, heat radiation, and convection heating. This allows for multi-dimensional circumferential heating of the aerosol-generating product 400, improving heating efficiency and energy utilization. Furthermore, the heat conduction and heat radiation methods compensate for temperature fluctuations caused by convection heating after extraction, facilitating rapid temperature recovery and ensuring full aerosol production upon re-extraction. This guarantees consistent aerosol release from the aerosol-generating product 400.

[0054] For example, please refer to Figure 1 and Figure 2 The protrusion 150 may include a first part 151 and a second part 152 integrally formed with the cup body 130. The first part 151 is disposed on the side wall of the heating cavity 110 and is disposed in a direction parallel to the axial direction of the heating cavity 110. The second part 152 is disposed on the bottom wall of the heating cavity 110 and is disposed in the radial direction of the heating cavity 110.

[0055] The first part 151 can extend to the product insertion port 111 at one end away from the second part 152, and the second part 152 can extend slightly towards the center of the bottom wall of the heating chamber 110 at one end away from the first part 151. This can be used to support the aerosol generating product 400 inserted in the heating chamber 110, so that a distance is maintained between the aerosol generating product 400 and the bottom wall of the heating chamber 110, so that hot airflow can enter the aerosol generating product 400.

[0056] Each protrusion 150 has a first portion 151 that can be configured to form a receiving area that conforms to the shape of the outer peripheral surface of the aerosol generating article 400, so that the aerosol generating article 400 can contact the first portion 151 when it is in the receiving area. The surfaces of the first portion 151 and the second portion 152 that contact the aerosol generating article 400 serve as heat conduction surfaces 153, and the surfaces of the first portion 151 and the second portion 152 that do not contact the aerosol generating article 400 serve as heat radiation surfaces 160. It can be understood that the surfaces of the cavity sidewalls and cavity bottom walls of the heating cavity 110 that do not have protrusions 150 can also serve as heat radiation surfaces 160.

[0057] In other embodiments, the first portion 151 may also be arranged in a spiral or other shape along the sidewall of the heating cavity 110, and the second portion 152 may extend along the bottom wall of the heating cavity 110 to connect with the second portion 152 of other protrusions 150. The second portion 152 may be arranged in a straight line, an arc, or a wave shape. In short, the shape of the first portion 151 and the second portion 152 is not limited, as long as they can be combined to form the heating air passage 120.

[0058] Examples of the heating non-combustion device in this application:

[0059] In one embodiment, please refer to Figure 4 The heated non-combustible device includes a power supply component 300 and a heating component as described in any of the above embodiments. The power supply component 300 is electrically connected to the heating element 100 and the temperature sensing module 200 to supply power to them. The power supply component 300 includes a counting unit, which is also electrically connected to the temperature sensing module 200 to accumulate the number of suctions based on the detection signal from the temperature sensing module 200.

[0060] Those skilled in the art will understand that, depending on the heating principle of the heating element 100, the power supply component 300 needs to provide the energy required by the heating element 100. For example, if the heating element 100 is a resistive heating element 100, such as including the heating circuit 140 described in the above embodiments, then the power supply component 300 can be a collection of related components such as the battery cell 320 and the circuit board 330 to provide electrical energy to the heating element 100. If the heating element 100 is an electromagnetic induction heating element 100, then the power supply component 300 also needs to include an electromagnetic coil or other elements capable of emitting an induced magnetic field to provide an induced magnetic field to the heating element 100, so that the heating element 100 can generate heat through induced eddy currents.

[0061] In one embodiment, please refer to Figure 4 The power supply component 300 includes a housing 310, a battery cell 320, and a circuit board 330. The counting unit can be integrated onto the circuit board 330. The housing 310 has a mounting member 340, which has a mounting cavity 341 for mounting the heating component. When the heating component is mounted in the mounting cavity 341, the heating element 100 has an isolation space 342 on its outer side. The temperature sensing module 200 is located in the isolation space 342, isolating it from the heating cavity 110 and the heating air passage 120. This prevents scale buildup on the temperature sensing module 200 due to aerosol residue adhesion and accumulation. Furthermore, the isolation space 342 can also form an air insulation layer outside the heating element 100, helping to reduce heat loss during heating and improve heating efficiency.

[0062] For example, please refer to Figure 4The housing 310 is provided with an insertion port 311. Inside the housing 310, corresponding to the insertion port 311, an installation component 340 is provided. The installation component 340 includes an installation tube 343 and a base 344 and a top cover 345 respectively installed at both ends of the installation tube 343. The installation tube 343, the base 344 and the top cover 345 together form an installation cavity 341. The top cover 345 is provided with a through hole corresponding to the insertion port 311. The heating component is installed in the installation cavity 341. The heating cavity 110 is connected to the insertion port 311 through the through hole. The temperature sensing module 200 can be set at the bottom of the cup body 130 and electrically connected to the circuit board 330 through the wire 210 passing through the base 344, so that the counting unit can receive the detection signal of the temperature sensing module 200, thereby accumulating the number of suction ports. Among them, the mounting tube 343, the base 344 and the top cover 345 can all be made of materials with low thermal conductivity, such as PEEK (polyether ether ketone) or PPSU (polyphenyl sulfone), in order to improve the insulation effect and reduce heat loss.

[0063] Please refer to Figure 4 A limiting protrusion 3441 may be provided on the inner wall of the mounting cavity 341 along the circumference of the mounting cavity 341. A protruding edge 131 is provided on the cup body 130 around the product insertion port 111. The protruding edge 131 can be engaged with the limiting protrusion 3441, so that the heating element 100 is hung in the mounting cavity 341, thereby forming an isolation space 342 between the outer side of the heating component and the cavity wall of the mounting cavity 341. The top cover 345 may also have a supporting part 3451, which can cooperate with the limiting protrusion 3441 to clamp the protruding edge 131, so as to fix the heating element 100 by limiting the protruding edge 131.

[0064] The power supply component 300 can also be used to support other functions of the heated non-combustible device, such as adjusting the heating power of the heating element 100 and displaying the status information of the heated non-combustible device.

[0065] In some embodiments, the circuit board 330 can be electrically connected to the heating line 140 in the heating element 100 via a wire 210. When the suction action occurs, after the counting unit counts according to the temperature detection signal of the temperature sensing module 200, the circuit board 330 can control the heating power of the heating element 100 to increase in a timely manner to perform heating temperature compensation and further improve the consistency of the suction taste.

[0066] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
