Description

Technical Field

[0001] This utility model relates to the field of novel tobacco product technology, particularly to the field of electrically heated aerosol generating devices, and more specifically to a heating control device and an aerosol generating device. Background Technology

[0002] New tobacco products refer to products that use non-combustible tobacco cartridges to replace traditional combustible cigarettes. These cartridges are inserted into a cigarette holder, where electric heating causes the aerosol-generating substances (such as tobacco and e-liquid) inside the cartridge to be heated and generate an aerosol for the user to inhale.

[0003] Currently, aerosol generators (also known as "electronic cigarettes") typically use button structures to input control signals, such as controlling heating after the cartridge is inserted. However, mechanical button structures experience physical wear and tear from repeated pressing, affecting the device's lifespan and leading to performance instability. Furthermore, electronic cigarettes are designed for portable use, and mechanical button structures are prone to accidental activation during transport, potentially wasting power and causing accidents, which is undesirable.

[0004] Furthermore, due to the design of the physical case structure, there are limitations in assembly and sealing performance, which affects the dustproof and waterproof effects. Utility Model Content

[0005] In view of the technical problems existing in the prior art of portable aerosol generators based on electric heating, according to the first aspect of the purpose of this utility model, a heating control device for an aerosol generator is proposed, comprising:

[0006] A chimney is defined as a channel that receives aerosol generating components from a predetermined direction.

[0007] An electric heating assembly for controlled heating of an aerosol generating assembly inserted into the channel; and

[0008] A control component, electrically connected to the electric heating component, is used to control the activation and / or heating power of the electric heating component;

[0009] The heating control device further includes:

[0010] A pair of pressure sensors are installed on the outer wall surface of the chimney, and the pair of pressure sensors are symmetrically distributed with respect to the central axis of the channel;

[0011] An insertion sensing part is installed on the inner wall surface of the chimney. The insertion sensing part is located in the sensing area defined by the pressure sensor. When the aerosol generating component enters the channel, it actuates the insertion sensing part, causing the insertion sensing part and / or the sensing area to deform and trigger the pressure sensor output.

[0012] The control component controls the activation of the electric heating component to heat the inserted aerosol generating component based on the output signal of the pressure sensor.

[0013] As an optional embodiment, the insertion sensing part is configured as a protruding structure extending from the inner wall surface of the chimney into the channel. In particular, each of the aforementioned pressure sensors is provided with a corresponding protruding structure, and the protruding structures on both sides are symmetrically distributed with respect to the central axis of the channel.

[0014] Therefore, by using symmetrical dual pressure sensors on the outer wall of the chimney and symmetrical insertion sensing parts (such as protruding structures) on the inner wall of the chimney for pressure sensing and triggering, when the aerosol generating component is inserted, the insertion sensing part deforms under pressure, triggering the sensor output. The control component then activates the electric heating component to heat the inserted aerosol generating component, promoting aerosol generation. By automatically sensing and detecting the insertion of the cartridge, the activation and ignition of the electric heating component are automatically controlled, eliminating the need for a separate ignition control button. This reduces false triggering and accidental heating, optimizes the lifespan and battery life of the portable aerosol generator, and improves user experience and safety. Furthermore, it eliminates the need for additional spring-like structures on the inner wall of the chimney as triggering devices, resulting in a more reliable structure.

[0015] Meanwhile, the design of reducing mechanical buttons on the surface of the aerosol generator of this utility model makes the surface of the aerosol generator product a single piece, which provides a better user experience and grip and carrying experience while improving waterproof and dustproof effects.

[0016] According to a second aspect of the present invention, an aerosol generating device is also provided, comprising:

[0017] Main support;

[0018] Battery components; and

[0019] Heating control device for the aerosol generator in the foregoing embodiments;

[0020] The chimney, electric heating component, control component, and battery component are all mounted on the main support.

[0021] The present invention proposes an aerosol generator with a detection function for smoke cartridges (i.e., aerosol generating components). It eliminates the need for a separate heating control button, reduces false triggering and accidental heating, optimizes the service life and battery life of portable aerosol generators, and improves user experience and safety.

[0036] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0037] Various aspects of the present invention are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments disclosed herein are not necessarily intended to include all aspects of the present invention. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed herein are not limited to any particular implementation. Furthermore, some aspects of the present invention can be used alone or in any suitable combination with other aspects disclosed herein.

[0038] like Figure 1 , Figure 12 As shown, the aerosol generating device according to this utility model includes a chimney 110, an electric heating component 120, a control component 130, and a battery component 140. The chimney 110, electric heating component 120, control component 130, and battery component 140 are all installed within a main support frame 100, which serves as the overall support structure. It should be understood that the chimney 110, electric heating component 120, control component 130, and battery component 140, which are connected and installed in conjunction with the main support frame 100, are all encapsulated in a housing and equipped with necessary charging interfaces, display screens, housing surface decorations, and decorative elements, thus constituting an aerosol generating device product.

[0039] It should be understood that the battery assembly, in particular, uses rechargeable batteries, such as lithium batteries and nickel-metal hydride batteries, to provide power to the electric heating assembly 120, the control assembly 130, and the sensors.

[0040] Combination Figure 1 as well as Figures 2-5 , Figures 6-8 , Figures 9-11 As shown, the chimney 110 defines a channel 111 for receiving aerosol generating components 200 from a predetermined direction.

[0041] The electric heating component 120 is used to controllably heat the aerosol generating component 200 inserted into the channel 111. In optional embodiments, the electric heating component 200 may employ resistance heating, electromagnetic heating, or other methods. For example, an annular heating coil may be arranged inside the chimney structure around the aforementioned channel 111, and a ferromagnetic material (such as a patch) may be placed inside the aerosol generating component 200, thereby heating the aerosol generating component 200 through electromagnetic induction.

[0042] Of course, in other embodiments, other suitable electric heating components with appropriate structural forms and appropriate installation positions / arrangements can be used to heat the aerosol generating component 200 inserted into the channel 111 to promote the generation of aerosols.

[0043] In an embodiment of this invention, the control component 130 is configured as a control motherboard, mounted on the main bracket 100, and electrically connected to the electric heating component 120 for controlling the activation and / or heating power of the electric heating component 120.

[0044] like Figures 1-5 As shown in the embodiment of this utility model, a pair of pressure sensors are installed on the outer wall surface (110a) of the chimney, namely the first pressure sensor 101a and the second pressure sensor 101b. The pair of pressure sensors (101a, 101b) are symmetrically distributed with respect to the central axis of the channel 111.

[0045] Meanwhile, an insertion sensing part 105 is provided on the inner wall surface 110b of the chimney. The insertion sensing part 105 is located in the sensing area defined by the first pressure sensor 101a and the second pressure sensor 101b, so that the aerosol generating component 200 can actuate the insertion sensing part 105 during the process of entering the channel, causing the insertion sensing part and / or sensing area to deform and trigger the output of this pair of pressure sensors (101a, 101b).

[0046] Furthermore, the control component 130 controls the activation of the electric heating component 120 to heat the inserted aerosol generating component based on the output signal of the pressure sensor.

[0047] like Figures 2-5 As shown, in the first embodiment of this utility model, the aforementioned insertion sensing part 105 is configured as a protruding structure extending from the inner wall surface 110b of the chimney towards the channel 111. In particular, the insertion sensing part is an elastomer structure, such as a thermosetting elastomer or a thermoplastic elastomer structure, such as an elastic rubber body (NR, IR, IIR, BR, SBR, EPM, EPDM, MVQ, etc. rubber products), TPE, TPU, etc., and is mounted and fixed to the surface of the inner wall surface 110b of the chimney in a structure similar to a seat.

[0048] As an example, each of the aforementioned pair of pressure sensors (first pressure sensor 101a and second pressure sensor 101b) is equipped with an insertion sensing unit 105, and the insertion sensing units 105 on both sides are symmetrically distributed with respect to the central axis of the channel 111. By designing the dual pressure sensors symmetrically distributed along the central axis of the channel, a single control strategy can be implemented, such as any sensor detection output being considered as detection of the aerosol generating component 200 inserting into the channel 111, automatically triggering the activation of the electric heating component 120 for ignition and heating; alternatively, dual-sensor output verification can be used, where both sensors detecting signal output are considered as detection of the aerosol generating component 200 inserting into the channel 111, thereby reducing false triggering.

[0049] In an optional embodiment, along the direction of the aerosol generating component 200 entering the channel 111, the contact surface between the protruding structure and the aerosol generating component 200 is configured as an inclined surface or an arc-shaped surface. This alleviates the rigid contact formed between the two when the aerosol generating component is inserted into the chimney, optimizing the contact and pressure transmission process in the entry channel.

[0050] In some alternative examples, the protruding structure may be designed with chamfered edges extending into the channel to optimize the contact and pressure transmission process into the channel.

[0051] Combination Figures 2-5 As shown, in an optional embodiment, the sensing area defined by the aforementioned pressure sensor includes the projection area of ​​the area covered by the aforementioned pressure sensor at the installation position on the outer wall surface 110a of the chimney onto the inner wall surface 110b of the chimney, and an extension area extending a predetermined distance below the projection area. In a particularly preferred example, the protruding structure is located within the aforementioned extension area.

[0052] As an optional embodiment, the preset distance for downward extension is typically designed to be between 1 and 20 mm.

[0053] Therefore, by optimizing the installation position of the insertion sensing part, it is staggered from the sensor and located within the effective sensing area of ​​the sensor. When the aerosol generating component is inserted into the chimney, the insertion sensing part is deformed due to pressure and / or causes deformation of the sensing area. Such deformation is detected by the sensor and triggers the sensor output.

[0054] In embodiments of this invention, the aforementioned pressure sensors (first pressure sensor 101a and second pressure sensor 101b) are particularly patch-type pressure sensors, attached to the outer wall surface of the chimney, directly sensing the deformation of the chimney's sidewall to generate an output. Optionally, a highly sensitive, small-sized, low-power sensor, such as the PrimeSemi, is particularly preferred. The PMDS-F2 / F3 stress sensor enables high-precision digital sampling of pressure.

[0055] In an optional embodiment, combined with Figures 6-8 As shown, the sidewall of the aforementioned chimney 110 has a groove 103 that at least partially surrounds the aforementioned sensing area. The aforementioned insertion sensing part 105 is located on the inner wall surface of the chimney defined by the aforementioned groove 103.

[0056] Preferably, the groove 103 is a U-shaped groove with its opening facing the inlet direction of the channel 111. This is more conducive to stress transmission and deformation. The symmetrical groove design on both sides of the U-shaped groove allows stress to be concentrated in the sensing area during the process of the aerosol generating component being inserted into the chimney and applying stress to the insertion sensing part, enabling rapid and effective sensing and reducing external vibration interference.

[0057] Combination Figures 9-11 As shown, in an optional embodiment, the insertion sensing unit 105 is an annular element 106 installed on the inner wall surface of the chimney 110. There are two first protrusions (106a, 106b) on the inner wall of the annular element 106, and the two first protrusions are symmetrically distributed with respect to the central axis of the channel 111. Two second protrusions (106a, 106b) corresponding to the positions of the two first protrusions are provided on the outer wall of the annular element. The two first protrusions abut against the aerosol generating component 200, and the two second protrusions pass through the holes provided on the side wall of the chimney 110 and abut against the pair of pressure sensors (101a, 101b).

[0058] As an optional implementation, the inner wall surface of the aforementioned chimney 110 is provided with a recessed step portion, and the aforementioned annular element 106 is installed in the aforementioned step portion, so that the installed annular element 106 maintains the same cylindricity as the inner wall surface of the aforementioned chimney 110.

[0059] In an optional embodiment, the control component 130 may be a low-power microprocessor module connected to the aforementioned pressure sensor and electric heating component, and control the activation and ignition of the electric heating component based on the output of the pressure sensor.

[0060] As an optional embodiment, the control component 130 includes a timer module 131 and a processing module 132.

[0061] The timer module 131 is configured to start sampling timing when the output signal of the pressure sensor is received;

[0062] In response to continuously receiving the output signal from the pressure sensor within a preset sampling period after the sampling timing is started, the processing module 132 controls the activation of the electric heating component 120 to heat the aerosol generating component 200 and generate aerosol.

[0063] As mentioned above, in terms of control strategy, either a single-sensor output control strategy or a dual-sensor output control strategy can be adopted.

[0064] Therefore, in conjunction with the implementation of the aerosol generating device in the above embodiments, compared with the prior art, given that the existing design relies on mechanical buttons for heating control, requiring users to actively press the buttons to activate the heating system, which poses risks of physical wear, accidental touches, and limited sealing performance, the aerosol generating device and its heating control scheme of this utility model eliminate independent mechanical buttons. Instead, it adopts a combined structure of dual pressure sensors and an insertion sensing unit. Heating is automatically triggered by detecting the insertion of the aerosol generating component (cartridge), achieving buttonless intelligent control. In particular, the symmetrical design of the dual sampling sensors and the verification of the sampling cycle avoid accidental heating caused by squeezing or accidental contact during transport, reducing power waste and the risk of localized high temperatures caused by accidental heating. Heating is automatically activated upon detecting valid insertion of the cartridge, requiring no additional button operation, conforming to the usage habits of plug-and-play portable devices, and improving the user experience.

[0065] Meanwhile, the aerosol generator proposed in this utility model solves the problems of poor contact and performance degradation caused by repeated pressing of traditional buttons by eliminating the physical wear of mechanical buttons. It also reduces gaps, enhances dustproof and waterproof performance, and improves the overall durability of the device.

[0066] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
