Description

Technical Field

[0001] This application relates to the field of tobacco production equipment technology, and in particular to an aerosol generating device. Background Technology

[0002] In heating devices for aerosol products, accurate monitoring of cigarette temperature is crucial for ensuring taste and safety. Existing devices often employ single-point fixed sensors, such as thermistors or thermocouples integrated into the heating element. These sensors are only used to monitor the highest temperature point of the heating element, or to measure the temperature at high-temperature points using the temperature-resistance characteristics (TCR) of the heating element itself. This results in temperature measurement blind spots. More importantly, because the transfer of heat from the heating element to the heated aerosol product requires time, the temperature values ​​monitored by the device system cannot accurately reflect the temperature of the aerosol heating medium.

[0003] Although in theory multiple sensors could be inserted into aerosol products to solve the above problems, in engineering practice, multi-directional insertion sensors require more mechanical structure support, and the limited volume of aerosol products and devices cannot meet the space requirements of multiple sensors. Summary of the Invention

[0004] The purpose of this application is to provide an aerosol generating apparatus that can perform full-range temperature detection when heating aerosol products.

[0005] To achieve the above objectives, this application provides an aerosol generating apparatus, comprising: a housing, a scanning temperature measurement component, and a control circuit board;

[0006] The top of the outer shell is provided with a receiving cavity, which can accommodate aerosol products; the scanning temperature measurement component includes an infrared transmission window, a scanning execution mechanism and a motion execution mechanism; the outer shell also has a main cavity, and a partition is provided between the main cavity and the receiving cavity; the scanning execution mechanism and the motion execution mechanism are located in the main cavity; the infrared transmission window is located in the partition; the motion execution mechanism is used to enable the scanning execution mechanism to perform non-fixed-point temperature monitoring of the receiving cavity area through the infrared transmission window;

[0007] The control circuit board is located in the main cavity, and the control circuit board is electrically connected to the heating element and the scanning temperature measurement component.

[0008] In some embodiments, the scanning actuator includes a guide rail, a sliding carrier, and an infrared sensor. The guide rail is disposed on the inner wall of the housing. The sliding carrier is slidably fitted to the guide rail and is capable of moving along the guide rail. The infrared sensor is fixedly disposed on the sliding carrier. The motion actuator includes a driving member connected to the sliding carrier and is used to drive the sliding carrier to reciprocate linearly along the guide rail.

[0009] In some embodiments, a position detection unit is further provided, which is used to provide real-time feedback on the position of the sliding carrier.

[0010] In some embodiments, the position detection unit comprises two touch switches, the distance between the two touch switches being the effective travel distance of the sliding carrier, allowing the sliding carrier to contact the touch switches. In some embodiments, a limit protection component is also provided to prevent the sliding carrier from impacting the housing.

[0011] In some embodiments, the position detection unit includes a miniature magnetic scale, a Hall sensor, and a limit protection component. The miniature magnetic scale is disposed on the control circuit board, the Hall sensor is disposed on the sliding carrier, and the limit protection component is used to limit the movement of the sliding carrier.

[0012] In some embodiments, the limiting protection component includes a first buffer block and a second buffer block, which are respectively disposed at both ends of the guide rail. Both the first buffer block and the second buffer block are flexible and can deform under external impact.

[0013] In some embodiments, the partition is a double-layer hollow structure, with an opening on the side of the partition near the receiving cavity, and the infrared transmission window is installed on the side away from the receiving cavity. The opening and the infrared transmission window are arranged opposite to each other, and the distance between the opening and the infrared transmission window is between 1 and 5 mm.

[0014] In some embodiments, a sealing element is provided between the infrared transmission window and the partition, the sealing element being used for an airtight connection between the infrared transmission window and the partition.

[0015] In some embodiments, a heating element is also provided, which can be disposed in the receiving cavity or in an aerosol product located in the receiving cavity.

[0016] In some embodiments, the scanning actuator includes a fixed bracket and an infrared sensor. The fixed bracket is fixedly mounted on the control circuit board, and the infrared sensor is fixedly mounted on the fixed bracket. The motion actuator is a MEMS micromirror assembly. The MEMS micromirror assembly is tilted between the infrared transmission window and the infrared sensor. The MEMS micromirror assembly has a movable mirror surface that can swing to achieve angular deflection, thereby changing the reflection path of infrared radiation light from the surface of the aerosol product and allowing the infrared radiation light from the surface of the aerosol product to enter the infrared sensor.

[0017] In some embodiments, the MEMS micromirror assembly and the infrared sensor are provided with an optical path isolation tube, which is used to shield stray light.

The aerosol generating apparatus of this application can perform non-fixed-point temperature detection of the aerosol generating substrate when heating the aerosol product, accurately locking hot spots and preventing localized overheating.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0033] The aerosol generator provided in this application includes a housing 1 and a scanning temperature measurement component. The housing 1 has a receiving cavity at its top. The scanning temperature measurement component includes an infrared transmission window 4, a scanning execution mechanism, and a motion execution mechanism. The housing 1 also has a main cavity, with a partition between the main cavity and the receiving cavity. The scanning execution mechanism and the motion execution mechanism are located in the main cavity. The infrared transmission window 4 is located in the partition. The motion execution mechanism enables the scanning execution mechanism to perform non-fixed-point temperature monitoring of the receiving cavity area through the infrared transmission window 4. A control circuit board is located in the main cavity and is electrically connected to the scanning temperature measurement component.

[0034] Understandably, the control circuit board 3 can supply power to the scanning temperature measurement component. When aerosol products are generated in the containment cavity, the motion actuator can move by its own movement or drive the scanning actuator to move, thereby enabling the scanning actuator to monitor the temperature of the aerosol products in the containment cavity through the infrared transmission window 4, so as to ensure that the monitored temperature data can accurately reflect the temperature of the aerosol heating medium.

[0035] Example 1

[0036] like Figures 1 to 4 As shown, in this embodiment, the scanning actuator includes a guide rail 6, a sliding carrier 7, and an infrared sensor 5. The guide rail 6 is disposed on the inner wall of the housing 1. The sliding carrier 7 is slidably fitted to the guide rail 6 and can move along the guide rail 6. The infrared sensor 5 is fixedly disposed on the sliding carrier 7. The motion actuator includes a drive member 8, which is connected to the sliding carrier 7 and is used to drive the sliding carrier 7 to reciprocate linearly along the guide rail 6.

[0037] Specifically, the outer shell 1 has a receiving cavity, the lower part of which is the main body cavity. A partition is provided between the receiving cavity and the main body cavity, and the control circuit board 3 is fixedly installed on the bottom surface of the main body cavity.

[0038] In this embodiment, a heating element 2 is disposed within the receiving cavity, and a fixing seat adapted to the receiving cavity is provided inside the outer shell 1. The fixing seat can fit against the inner wall of the receiving cavity to achieve a sealed receiving cavity. The heating element 2 is fixed by the fixing seat and can be inserted into the aerosol product. The positive and negative electrodes of the heating element 2 are electrically connected to the control circuit board 3, so that the control circuit board 3 can supply power to the heating element 2. In some other embodiments, the heating element 2 can be located inside the aerosol product, with conductive pins leading out from the outer wall of the aerosol product. The cavity wall is provided with electrode plates corresponding to the conductive pins. The electrode plates are electrically connected to the control circuit board. When the aerosol product is inserted into the receiving cavity, and the conductive pins contact the electrode plates, the conductive pins and electrode plates are electrically connected, and the control circuit board can supply power to the heating element 2 inside the aerosol product to heat the aerosol product.

[0039] The guide rail 6 can be a lead screw precision machined from stainless steel with external threads. The axis of the guide rail 6 is parallel to the axis of the aerosol product. Two support frames are provided at both ends of the guide rail 6, and each support frame has two coaxially distributed mating holes. The guide rail 6 is rotatably fitted into the mating holes of the two support frames via bearings, allowing the guide rail 6 to rotate. In other embodiments, the lead screw can be injection molded from LCP (liquid crystal polymer), POM (polyoxymethylene), or PA (polyamide) to reduce the coefficient of friction.

[0040] The sliding carrier 7 can be a lightweight slider, which is injection molded from plastic to reduce weight and improve response speed. The slider has internal helical threads that match the threads of the guide rail 6. The infrared sensor 5 can be a single-point infrared sensor 5, which is fixedly embedded in the sliding carrier 7.

[0041] The driving component 8 can be a micro-stepping motor with a diameter of 6 mm. The central axis of the driving component 8 is an extension of the guide rail 6 and serves as the mover of the motor. The stator of the motor is fixedly mounted on the support frame. When the driving component 8 is started, the lead screw rotates. Through the matching of the lead screw thread and the sliding block thread, the rotation is converted into linear displacement, so that the sliding carrier 7 can move along the axial direction of the lead screw. Through the periodic reciprocating movement of the sliding carrier 7 along the lead screw, the infrared sensor 5 can monitor the heating temperature of the aerosol product in the cavity and feed the data back to the control circuit board 3. By comparing with the preset target, the power duty cycle is adjusted in time to control the temperature of the heating element 2 until it is consistent with the preset target, thus ensuring the heating uniformity and taste consistency of the aerosol product.

[0042] Preferably, a position detection unit is also provided, which is used to provide real-time feedback on the position of the sliding carrier 7.

[0043] It is understandable that by setting up a position detection unit, the absolute position of the sliding carrier 7 can be calculated, thus achieving a precise correspondence between the position monitored by the infrared sensor 5 and the monitored temperature.

[0044] Preferably, the position detection unit consists of two touch switches 9, the distance between the two touch switches 9 is the effective travel of the sliding carrier 7, and the sliding carrier 7 can touch the touch switches 9.

[0045] Specifically, two touch-type switches 9 are sequentially attached at a certain distance to one side of the guide rail 6, which is close to the control circuit board 3. Each touch-type switch 9 is electrically connected to the control circuit board 3. The distance between the two touch-type switches 9 is the effective travel distance of the sliding carrier 7. In this embodiment, the distance between the two touch-type switches 9 is also equal to the length of the aerosol generating substrate. The end face of the touch-type switch 9 is a micro-motion self-reactive contact. When the sliding carrier 7 touches the contact, the control circuit board 3 detects the signal to start, stop, or reciprocate the displacement, and at the same time determines and records the temperature data monitored by the infrared sensor 5, indicating that a certain end of the aerosol generating substrate has been reached. In some other embodiments, a miniature magnetic grating ruler can be set within the projection area of ​​the control circuit board 3 of the sliding carrier 7's displacement travel distance. A Hall sensor is installed on the sliding carrier 7. When the sliding carrier 7 moves, the Hall sensor outputs a pulse signal, which the MCU uses to calculate the absolute position of the sliding carrier 7.

[0046] Preferably, a limiting protection component is also provided to prevent the sliding carrier 7 from impacting the housing.

[0047] Specifically, the limit protection component includes a first buffer block and a second buffer block, which are respectively disposed at both ends of the guide rail 6. Both the first buffer block and the second buffer block are flexible and can deform under external impact.

[0048] It is understandable that when the sliding carrier 7 moves to its limit position, the sliding carrier 7 comes into contact with the first buffer block or the second buffer block. At the moment of contact, the first buffer block or the second buffer block can deform to reduce the impact force between them and achieve buffering, thereby protecting the sliding carrier 7 and the infrared sensor 5. At the same time, the first buffer block or the second buffer block can limit the sliding carrier 7 to prevent the sliding carrier 7 from continuing to move.

[0049] Preferably, the partition is a double-layer hollow structure, the infrared transmission window 4 is installed on the inner wall away from the receiving cavity, and the inner surface of the infrared transmission window 4 is kept at a distance from the surface of the aerosol product.

[0050] Specifically, the outer shell 1 includes a first outer shell 101, a second outer shell 102, a first inner shell 103, a second inner shell 104, and a third inner shell 105. The first outer shell 101 and the second outer shell 102 can form a hollow shell structure for the user to hold. The first inner shell 103, the second inner shell 104, and the third inner shell 105 are sequentially arranged inside the hollow shell structure formed by the first outer shell 101 and the second outer shell 102. By separating the internal space of the hollow shell structure, a receiving cavity and a main body cavity are formed. The second inner shell 104 and the third inner shell 105 are both provided with a sleeve structure. The two sleeve structures have different diameters and are coaxially distributed to form a double-layer hollow partition between the receiving cavity and the main body cavity.

[0051] Understandably, the inner layer of the partition has a detection hole that exposes the aerosol generating substrate, allowing the infrared sensor 5 to detect the aerosol generating substrate through the infrared transmission window 4. The center of the detection hole is aligned with the center of the infrared transmission window 4, and the area of ​​the detection hole is smaller than the area of ​​the infrared transmission window 4. The gap between the inner and outer layers of the partition is 1-5 mm to prevent the heat from the aerosol product from being rapidly transferred to the infrared sensor 5 when heated.

[0052] Preferably, a sealing element is provided between the infrared transmission window 4 and the partition, and the sealing element is used for the airtight connection between the infrared transmission window 4 and the partition.

[0053] Specifically, the infrared transmission window 4 is aligned with the infrared sensor 5 in terms of wavelength to ensure high infrared transmittance. If the infrared sensor 5's wavelength is between 8-14 micrometers, the window lens is made of zinc sulfide or zinc selenide with a protective film. If the infrared sensor 5's wavelength is between 3-5 micrometers, the window lens material can be fused glass or sapphire. A seal, which can be a flexible sealing ring, is provided between the infrared transmission window 4 and the partition to further prevent heat transfer to the infrared sensor 5.

[0054] Example 2

[0055] like Figures 5 to 8 As shown, in this embodiment, the scanning actuator includes a fixed bracket 10 and an infrared sensor 5. The fixed bracket 10 is fixedly mounted on the control circuit board 3, and the infrared sensor 5 is fixedly mounted on the fixed bracket 10. The motion actuator is a MEMS micro-mirror assembly 11. The MEMS micro-mirror assembly 11 is tilted between the infrared transmission window 4 and the infrared sensor 5. The MEMS micro-mirror assembly 11 has a movable mirror 111. The movable mirror 111 can swing to achieve angle deflection, thereby changing the reflection path of infrared radiation light from the surface of the aerosol product and allowing the infrared radiation light from the surface of the aerosol product to enter the infrared sensor 5.

[0056] Specifically, this embodiment demonstrates a structure for optical path deflection. The outer shell 1, the receiving cavity, the heating element 2, and the infrared transmission window 4 in this embodiment are the same as in Embodiment 1. This embodiment replaces the linear reciprocating mechanical module of Embodiment 1 with an optical module.

[0057] The fixed bracket 10 is fixedly mounted on the control circuit board 3. The infrared sensor 5 is a single-point infrared sensor 5, which is installed on the horizontal plane of the fixed bracket 10, with its direction parallel to the insertion direction of the aerosol product.

[0058] The MEMS micromirror assembly 11 is mounted on the vertical surface of the fixed bracket 10 and is located directly in front of the lens of the infrared sensor 5. The movable mirror 111 is the micro-vibration reflector of the MEMS micromirror assembly 11. The movable mirror 111 is rotatably connected to the fixed bracket 10 via a swing beam. The movable mirror 111 is tilted at a 45-degree angle to the lens of the infrared sensor 5 to ensure optical path alignment. The MEMS micromirror assembly 11 also has a micro actuator for driving the movable mirror 111 to rotate. The MEMS micromirror assembly 11 is electrically connected to the control circuit board 3 via a flexible PCB.

[0059] When the movable mirror 111 swings ±θ degrees around its axis, the angle of the reflected light changes by 2θ degrees. By designing the swing amplitude of the movable mirror 111, the projection of the reflected light onto the heating chamber window sweeps from the bottom to the top of the cigarette, thus achieving full-area temperature monitoring. In this embodiment, the maximum swing angle of the movable mirror 111 is 30 degrees. When the movable mirror 111 swings 15 degrees clockwise, as... Figure 6 As shown, the reflection temperature is projected onto the aerosol product generating matrix at the root of the aerosol generating matrix. When the movable mirror 111 is rotated counterclockwise by 15 degrees, as... Figure 7 As shown, the reflected temperature is projected onto the top of the aerosol generating substrate. The movable mirror 111 reflects light towards the lens of the infrared sensor 5, and the infrared sensor 5 feeds back the monitored temperature data to the control circuit board 3.

[0060] Preferably, the MEMS micro-mirror assembly 11 and the infrared sensor 5 are provided with an optical path isolation cylinder 12, which is used to shield stray light.

[0061] Specifically, the inner wall of the optical path isolation cylinder 12 is blackened. The optical path isolation cylinder 12 can limit the field of view of the infrared sensor 5 lens, ensuring that the sensor can only receive the light reflected by the movable mirror 111, and cannot directly see other heat sources, thereby improving the signal-to-noise ratio and improving the accuracy of temperature monitoring.

[0062] In summary, the aerosol generating apparatus of this application can perform full-range temperature detection of the aerosol generating matrix when heating aerosol products, accurately locate hot spots, and prevent local overheating.

[0063] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
