Abstract
Description
Technical Field
[0001] This application relates to the field of aerosol generation equipment technology, specifically to a heating non-combustible device. Background Technology
[0002] A heated non-combustible device is an aerosol generating device that heats the matrix segment of an aerosol generating product, causing the aerosol generating product to produce aerosols in a non-combustible state. Heated non-combustible devices typically have a matrix inlet, and the aerosol generating products used with them are mostly rod-shaped or columnar. In use, the matrix segment of the aerosol generating product needs to be inserted into the heated non-combustible device through the matrix inlet for heating by the heating element within the device.
[0003] For ease of use, some heated tobacco products are equipped with an aerosol-generating product insertion detection function to automatically activate heating after the aerosol-generating product is inserted. This insertion-based self-starting function is generally achieved through infrared detection, which requires strict design of the sensor position and fixing method within the confined space of the heated tobacco product to ensure that the infrared light signal is stably blocked or reflected when the cigarette is inserted, posing a challenge to the structure. Utility Model Content
[0004] In order to improve the problem of high structural requirements for the implementation of the insertion self-starting function, this application provides a new heating non-combustion device.
[0005] One embodiment provides a heating non-combustible device, comprising:
[0006] The housing has a mounting cavity and a product socket, the product socket being used for inserting an aerosol-generated product into the mounting cavity;
[0007] A heating component is disposed within the mounting cavity and facing the product insertion port, for heating the inserted aerosol-generated product;
[0008] The mounting bracket is fixed inside the mounting cavity to support the heating assembly;
[0009] A pressure sensor is disposed between the heating component and the mounting bracket to sense the pressure change generated by the squeezing of the heating component when the aerosol generating article is inserted.
[0010] And a control module, electrically connected to the pressure sensor, for receiving the sensing signal from the pressure sensor to control the heating assembly to start or stop.
[0011] In one embodiment, the heating assembly includes a base and a heating element, the heating element being fixedly disposed on the base, and the heating element having an insertion portion for penetrating the interior of the aerosol generating article;
[0012] The mounting bracket supports the heating component by supporting the base. The pressure sensor is sandwiched between the base and the mounting bracket to sense pressure changes in the heating component caused by the insertion and removal of the aerosol-generated product. The control module controls the start and stop of the heating element.
[0013] In one embodiment, the heating element is embedded in the base, and the heating element and the base are integrally formed by injection molding.
[0014] In one embodiment, the mounting bracket has a receiving cavity for accommodating the seat body to limit the displacement of the seat body along the radial direction of the receiving cavity; the cavity wall of the receiving cavity has a supporting step surface, the pressure sensor is disposed on the supporting step surface, the seat body has a pressure transmitting boss facing the pressure sensor, and the supporting step surface supports the pressure transmitting boss through the pressure sensor to limit the displacement of the heating component along the insertion direction of the aerosol generating article.
[0015] In one embodiment, the mounting bracket is provided with a limiting surface, the limiting surface is arranged in a direction away from the insertion port of the product, the base has a protrusion, and the limiting surface abuts against the protrusion to limit the displacement of the heating component along the direction of pulling out the aerosol-generating product.
[0016] In one embodiment, the heated non-combustible device further includes an isolating member disposed within the mounting cavity and located between the article insertion port and the base. The isolating member has a stop surface for limiting the insertion depth of the aerosol-generating article to prevent the aerosol-generating article from contacting the base.
[0017] In one embodiment, the isolation member includes a cylindrical part and a stop part. The cylindrical part has a guide channel for inserting the aerosol generating article. The stop part is disposed at one end of the guide channel away from the article insertion port. The end face of the stop part forms the stop surface. The stop part is provided with an insertion hole. The insertion part of the heating element passes through the insertion hole and extends into the guide channel.
[0018] In one embodiment, the diameter of the insertion hole is larger than the outer diameter of the insertion part, so that an annular gap is formed between the peripheral wall of the insertion part and the wall of the insertion hole, which is used to limit the transmission of pressure from the isolation member to the insertion part.
[0019] In one embodiment, the housing has a tubular extension in the mounting cavity corresponding to the product insertion port, and the spacer is nested in the tubular extension;
[0020] The end of the tubular extension away from the product insertion port is sealed to the mounting bracket by a first sealing element. A second sealing element is provided between the base and the mounting bracket to form an isolation space between the cylindrical part and the tubular extension, which is used to prevent aerosol from diffusing into the mounting cavity.

[0022] According to the heated non-combustible device of the above embodiment, a mounting bracket is provided in the mounting cavity of the housing to support the heating component, and a pressure sensor is provided between the heating component and the mounting bracket. The pressure sensor senses the pressure change caused by the aerosol generating product being inserted and squeezed onto the heating component. The control module can determine whether the aerosol generating product has been inserted or removed based on the sensed pressure change, thereby controlling the start and stop of the heating component. Unlike the infrared detection scheme that requires precise alignment of the infrared transmitter and receiver, this method only requires placing the pressure sensor between the heating component and the mounting bracket, which helps to reduce the requirements for structural design and manufacturing process and facilitates the realization of the self-starting function.
[0023] Furthermore, infrared detection solutions are easily affected by ambient light, and reducing the risk of false triggering requires higher control of the control module. In contrast, pressure sensors determine insertion actions based on physical contact, have strong anti-interference capabilities, are not easily triggered by false triggering, and help reduce control requirements.

[0039] 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.
[0040] 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.
[0041] 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).
[0042] Some heated tobacco products (HTPs) are equipped with an aerosol-generating product 800 insertion detection function to automatically activate heating after the aerosol-generating product 800 is inserted. This insertion-based self-starting function is generally achieved through infrared detection. Infrared detection requires precise alignment of the infrared emitter (such as an infrared LED) and receiver (such as a photosensitive sensor) to form a stable light path. Within the confined space of the HTP, the sensor position and fixing method must be meticulously designed to ensure stable blocking or reflection of the infrared light signal when the cigarette is inserted, placing high demands on the structure.
[0043] Furthermore, infrared signals are easily interfered with by factors such as ambient light and surface reflection of aerosol-generated products 800, resulting in a high risk of false triggering. To reduce the risk of false triggering, special design of the control module 500 is required, such as filtering, denoising, and dynamic threshold judgment of the signal through circuits or algorithms. This places high demands on the control module 500.
[0044] In this embodiment, a pressure sensor 400, triggered by the pressure of the heating component 200, is used. Utilizing the characteristic that the insertion of the aerosol-generating article 800 into the device causes a pressure change in the heating component 200, the pressure sensor 400 can sense this pressure change and send the signal to the controller. This allows the heating component 200 to automatically start based on the pressure change caused by the insertion of the aerosol-generating article 800. Since the pressure sensor 400 only needs to be triggered by the heating component 200, its placement and configuration can be flexible, reducing structural requirements. Furthermore, the pressure sensor 400 determines the insertion action based on physical contact, exhibiting strong anti-interference capabilities and being less prone to false triggering, further reducing control requirements.
[0045] One embodiment provides a heating non-combustible device, please refer to... Figures 1-6 The heated non-combustible device includes: a housing 100, a heating component 200, a mounting bracket 300, a pressure sensor 400, and a control module 500.
[0046] Please refer to Figure 1 The housing 100 can be understood as the main component constituting the external outline and structural frame of the heated non-combustible device, through which the heated non-combustible device can be held, moved, and used. The housing 100 has a mounting cavity 110 and a product insertion port 120. The mounting cavity 110 can be understood as the inner cavity of the housing 100, serving as a mounting space for other components in the heated non-combustible device. The product insertion port 120 is used for inserting the aerosol generating product 800 into the mounting cavity 110. It is understood that, depending on design and usage requirements, the aerosol generating product 800 can be fully inserted into the mounting cavity 110, or partially inserted, for example, only the matrix segment of the aerosol generating product 800 used to generate aerosols can be inserted.
[0047] The mounting bracket 300 can be understood as a support structure fixed to the mounting cavity 110, used to position the heating component 200 and / or other components, for example, to support the heating component 200. The mounting bracket 300 can be integrally provided with the housing 100, that is, the mounting bracket 300 is part of the housing 100, which is equivalent to the heating component 200 being supported by the housing 100; the mounting bracket 300 can also be provided in the mounting cavity 110 in any other detachable or non-detachable manner.
[0048] The heating component 200 can be understood as a heat-generating module in a non-combustible heating device. The heating component 200 is disposed within the mounting cavity 110 and faces the product insertion port 120, and is used to heat the aerosol-generating product 800 inserted into the mounting cavity 110. It is understood that the specific structure and heating method of the heating component 200 are not limited; for example, it can be a central heating method or a circumferential heating method. In short, it can contact the aerosol-generating product 800 inserted into the mounting cavity 110 and transfer heat to the aerosol-generating product 800.
[0049] In one embodiment, a pressure sensor 400 may be disposed between the heating assembly 200 and the mounting bracket 300 to sense the pressure change generated by the compression of the heating assembly 200 when the aerosol-generating article 800 is inserted. The control module 500 may be a circuit board disposed within the mounting cavity 110. The control module 500 is electrically connected to the pressure sensor 400 to receive the sensing signal from the pressure sensor 400, and is also electrically connected to the heating assembly 200 to control the activation of the heating assembly 200.
[0050] When the aerosol generating product 800 is inserted into the mounting cavity 110 and compresses the heating component 200, the heating component 200 will compress the pressure sensor 400, thereby generating pressure on the pressure sensor 400. The pressure sensor 400 can send a sensing signal to the control module 500 according to the pressure rise. When the control module 500 receives the sensing signal, it can control the heating component 200 to start, thereby realizing the self-starting function of inserting the aerosol generating product 800.
[0051] In a further embodiment, the control module 500 can also be used to control the heating component 200 to shut down. When the aerosol-generating product 800 is pulled out, the pressure on the heating component 200 decreases, and the pressure on the pressure sensor 400 also decreases accordingly. The pressure sensor 400 sends a sensing signal to the control module 500 based on the decrease in pressure. Upon receiving the sensing signal, the control module 500 can control the heating component 200 to stop heating, thereby further realizing the automatic shutdown function when the aerosol-generating product 800 is pulled out.
[0052] It is understandable that the pressure on the pressure sensor 400 fluctuates during the insertion and removal of the aerosol-generated product 800. Therefore, the control module 500 can start or stop the heating component 200 when the pressure on the pressure sensor 400 is relatively stable. For example, when the pressure fluctuation range is less than a set threshold (such as ±5%) and remains stable for more than 1 second, the heating component 200 can be controlled to start or stop, which helps to reduce the risk of accidental start-up or shutdown of the heating non-combustible device during use.
[0053] Furthermore, the control module 500 can also be electrically connected to other electrical components in the heated non-combustible device (such as status indicator lights, power display units, etc.) to control the start and stop of the heating component 200 together, which helps to enrich the self-starting and self-stopping functions of the heated non-combustible device.
[0054] The heating non-combustible device may also include a battery cell 600, which can be installed in the mounting cavity 110 in any detachable or non-detachable manner, or can be installed independently outside the housing 100.
[0055] Although both circumferential heating (e.g., providing a tubular heating element 220 for insertion of the aerosol generating article 800) and central heating (e.g., providing a needle-shaped heating element 220 for insertion into the aerosol generating article 800) can induce pressure fluctuations in the pressure sensor 400, in some embodiments, the pressure fluctuations caused by the insertion and removal of the aerosol generating article 800 are more pronounced due to the tighter connection between the centrally heated heating component 200 and the aerosol generating article 800, which helps in determining whether an insertion or removal of the aerosol generating article 800 has occurred.
[0056] Therefore, in one embodiment, please refer to Figure 2 The heating assembly 200 may include a base 210 and a heating element 220. The heating element 220 is fixedly disposed on the base 210 and has an insertion part 221 for penetrating into the interior of the aerosol generating article 800, so as to heat from the interior of the aerosol generating article 800 in the form of central heating.
[0057] The mounting bracket 300 can support the heating component 200 through the support base 210. The pressure sensor 400 is clamped between the base 210 and the mounting bracket 300 and can sense the pressure change of the heating component 200 caused by the insertion and removal of the aerosol generating product 800. The control module 500 then controls the heating element 220 to start and stop.
[0058] In some embodiments, the heating element 220 can be embedded within the base 210, and the heating element 220 and the base 210 are integrally molded by injection molding. That is, the heating element 220 is fixed to the base 210 by insert injection molding, which helps to reduce the risk of separation between the heating element 220 and the base 210 and improves the reliability of pressure transmission. In other embodiments, the heating element 220 can also be connected to the base 210 by adhesive, snap-fit, or other connection methods that can achieve reliable fixation.
[0059] It is understood that the specific structure of the mounting bracket 300 is not limited, as long as it can be used to support the heating component 200 so that the pressure of the heating component 200 being squeezed by the aerosol generating product 800 can be transmitted to the pressure sensor 400.
[0060] In one embodiment, to prevent the heating component 200 from shifting during use, please refer to... Figures 1-3 The mounting bracket 300 may have a receiving cavity 310 for accommodating the seat 210, thereby limiting the displacement of the seat 210 along the radial direction of the receiving cavity 310. Furthermore, the cavity wall of the receiving cavity 310 may have a supporting step surface 311, on which the pressure sensor 400 is disposed. The seat 210 has a pressure transmitting boss 2111 facing the pressure sensor 400. The pressure transmitting boss 2111 is supported on the supporting step surface 311 by the pressure sensor 400, thereby limiting the displacement of the heating component 200 along the insertion direction of the aerosol generating product 800. This helps to prevent the heating component 200 from being squeezed and displaced when the aerosol generating product 800 is inserted, which could lead to a deviation in the sensing of the pressure sensor 400.
[0061] For further details, please refer to... Figures 1-3The mounting bracket 300 may also be provided with a limiting surface 321, which is set in the direction away from the product insertion port 120. The base 210 has a protrusion 2121, and the limiting surface 321 abuts against the protrusion 2121 to limit the displacement of the heating component 200 along the direction of pulling out the aerosol generating product 800. This helps to avoid the situation where the heating component 200 is displaced and then resets when the aerosol generating product 800 is pulled out, which would affect subsequent use.
[0062] For example, the mounting bracket 300 has a boss 330 at one end near the product insertion port 120. A stepped hole is provided through the boss 330 to form a receiving cavity 310 facing the product insertion port 120, and an annular support step surface 311 facing the product insertion port 120 is formed on the cavity wall of the receiving cavity 310. A limiting claw 320 is provided on the cavity wall of the receiving cavity 310 away from the product insertion port 120, and a limiting surface 321 is provided on the limiting claw 320.
[0063] The pressure sensor 400 is disposed on the support step surface 311 and can be designed as a ring structure to fit the shape of the support step surface 311, so as to match the shape of the support step surface 311 and help the support step surface 311 provide sufficient support for the pressure sensor 400.
[0064] Please refer to Figure 2 The heating element 220 can be needle-shaped to pierce the interior of the aerosol generating article 800. The base 210 includes a first part 211 and a second part 212. The first part 211 is disposed on the side of the second part 212 near the article insertion port 120. The first part 211 can be cylindrical to fit the receiving cavity 310. The heating element 220 passes through the middle of the first part 211 along the axial direction. A pressure transmitting boss 2111 is formed at the end of the first part 211 near the article insertion port 120, thereby mounting on the pressure sensor 400.
[0065] The second part 212 can be arranged in a U-shaped frame, through which the connecting cable of the heating element 220 can pass and be electrically connected to the controller. The end of the second part 212 opposite to the first part 211 has a protruding portion 2121 for abutting against the limiting surface 321. Through the cooperation of the supporting step surface 311 and the pressure transmitting boss 2111, and the cooperation between the limiting surface 321 and the protruding portion 2121, axial positioning of the seat 210 is achieved, preventing the aerosol-generating product 800 from displacing the heating component 200 during insertion and removal.
[0066] To avoid the aerosol generating article 800 being over-inserted and affecting the detection of the pressure sensor 400, in one embodiment, please refer to... Figure 1 and Figure 3The heated non-combustible device also includes an isolator 700, which is disposed in the mounting cavity 110 and located between the article insertion port 120 and the seat 210. The isolator 700 has a stop surface for limiting the insertion depth of the aerosol generating article 800 to prevent the aerosol generating article 800 from contacting the seat 210.
[0067] The isolation element 700 helps to prevent excessive insertion of the aerosol generating article 800, thereby reducing the risk that the pressure sensor 400's sensing is affected by user operation; and it also helps to reduce the pressure sources sensed by the pressure sensor 400, which helps to reduce interference and improve sensing accuracy.
[0068] It is understandable that the specific configuration of the isolation component 700 is not limited, as long as it has a stop surface that can limit the contact between the aerosol generating product 800 and the seat 210.
[0069] In one embodiment, please refer to Figure 3 and Figure 4 The isolator 700 may include a cylindrical portion 710 and a stop portion 720. The cylindrical portion 710 has a guide channel 711 for inserting the aerosol generating article 800, which can guide the insertion and removal of the aerosol generating article 800 so that the aerosol generating article 800 is in a preset heated position after insertion. The stop portion 720 is disposed at one end of the guide channel 711 away from the article insertion port 120. The end face of the stop portion 720 forms a stop surface. The stop portion 720 is provided with an insertion hole 721. The insertion portion 221 of the heating element 220 passes through the insertion hole 721 and extends into the guide channel 711, so that when the aerosol generating article 800 is inserted to abut against the stop portion 720, the heating element 220 is inserted to a specific length of the aerosol generating article 800. This allows the user to insert the aerosol generating article 800 without having to consider the insertion depth, which helps to further reduce the difficulty of use and improve the ease of operation.
[0070] Furthermore, the diameter of the socket 721 can be larger than the outer diameter of the insertion part 221, so that an annular gap 7211 is formed between the peripheral wall of the insertion part 221 and the wall of the socket 721, to prevent the isolator 700 from contacting the insertion part 221, thereby limiting pressure transmission. This arrangement not only helps to prevent the isolator 700 from interfering with the pressure transmission of the heating component 200, but also ensures that the pressure change generated by the insertion and removal of the aerosol generating product 800 can only be transmitted to the base 210 through the heating element 220, and then to the pressure sensor 400, making the pressure transmission path unique and helping to further improve the sensing accuracy.
[0071] The aerosol generated by heating aerosol product 800 may enter the mounting cavity 110 through the annular gap 7211 during the suction interval. During long-term use, the condensate generated by the aerosol condensation or the scale deposited by the adhesion may cause malfunctions of components such as the control module 500 in the mounting cavity 110, affecting the service life of the heating non-combustible device.
[0072] In one embodiment, please refer to Figure 3 The housing 100 has a tubular extension 130 in the mounting cavity 110 corresponding to the product insertion port 120, and the isolation member 700 is nested in the tubular extension 130. The end of the tubular extension 130 facing away from the product insertion port 120 is sealed to the mounting bracket 300 by a first sealing member 131. A second sealing member 331 is provided between the base 210 and the mounting bracket 300 to form an isolation space 132 between the cylindrical part 710 and the tubular extension 130 to prevent aerosol from diffusing into the mounting cavity 110.
[0073] For example, please refer to Figure 3 and Figure 5 The housing 100 may include a main body 140 and an additional part 150. The main body 140 may be integrally formed or assembled from multiple parts. The additional part 150 may be installed on the main body 140 to form an installation cavity 110 with the main body 140. The product insertion port 120 and the tube extension are correspondingly provided on the additional part 150 for production and assembly.
[0074] The end of the tubular extension 130 facing away from the product insertion port 120 can be fitted onto the boss portion 330. The first sealing element 131 can be a sealing ring to seal the gap between the outer peripheral wall of the boss portion 330 and the inner wall of the tubular extension 130. The end face of the tubular extension 130 facing away from the product insertion port 120 can also abut against the mounting bracket 300. In this case, the first sealing element 131 can also be a sealing gasket to seal the gap between the end face of the tubular extension 130 and the mounting bracket 300.
[0075] The second sealing element 331 can also be a sealing ring; for example, an annular groove 2112 can be provided on the peripheral wall of the first part 211 of the seat 210, and a sealing ring can be fitted in the annular groove 2112 to seal the gap between the peripheral wall of the first part 211 and the cavity wall of the receiving cavity 310. Setting the second sealing element 331 as a sealing ring also helps to keep the seat 210 in a centered position after it is assembled in the receiving cavity 310, thus improving the assembly accuracy.
[0076] In summary, the configuration of the first seal 131 and the second seal 331 is not limited, as long as it meets the sealing requirements in design and use.
[0077] While using the tubular extension 130 to isolate the separator 700 can block aerosol diffusion, it also allows outside air to enter the isolation space 132 only through the matrix inlet, affecting the gas supply to the aerosol-generating article 800. Therefore, in a further embodiment, please refer to... Figure 3 The housing 100 may be provided with an air inlet 160, which is connected to the isolation space 132; the stop portion 720 is provided with a plurality of air guide holes 722 around the insertion hole 721, so that the external air entering the isolation space 132 from the air inlet 160 flows into the guide channel 711.
[0078] For example, please refer to Figure 3 and Figure 6 The housing 100 may also include a suction nozzle 170, which is mounted on the attachment 150. A matrix insertion port is provided on the suction nozzle 170. A notch is provided at the connection between the attachment 150 and the suction nozzle 170 to serve as an air inlet 160. The air inlet 160 is connected to the lumen of the tubular extension 130, so that external air can enter the isolation space 132 through the air inlet 160 and then flow into the guide channel 711 through the air guide hole 722, thereby supplying the aerosol generating product 800 to maintain the air pressure balance during suction.
[0079] Furthermore, the manner in which the spacer 700 is disposed within the tubular extension 130 is not limited. For example, please refer to... Figure 4 The outer wall of the cylindrical part 710 is provided with a first limiting boss 712 and a second limiting boss 713. The first limiting boss 712 and the second limiting boss 713 can be arranged at intervals along the axial direction of the cylindrical part 710, and multiple of them can be arranged around the circumference of the cylindrical part 710.
[0080] Please refer to Figure 7 The nozzle portion 170 has a first claw 171 extending into the cavity of the tubular extension portion 130. The first claw 171 may be provided with a limiting groove 1711 for the first limiting boss 712 to be inserted. The first claw 171 abuts against the first limiting boss 712 to limit the displacement of the cylindrical portion 710 toward the product insertion port 120. The inner wall of the tubular extension portion 130 is provided with a second claw 133. The second claw 133 abuts against the second limiting boss 713 to limit the displacement of the cylindrical portion 710 toward the mounting bracket 300.
[0081] The combination of the first limiting boss 712, the second limiting boss 713, the first pawl 171, and the second pawl 133 helps to form a bidirectional positioning structure, which facilitates the assembly of the isolation component 700.
[0082] It is understood that in other embodiments, only the stop portion 720 can be used as the isolation member 700, that is, the cylindrical portion 710 can be omitted, which can achieve the isolation of the aerosol generating product 800 and the base 210. The isolation member 700 can also be provided in the tubular extension portion 130 in other detachable or non-detachable manner.
[0083] 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.
