Abstract

The application provides a heating control device, a control method and an aerosol generating device. The aerosol generating device comprises a smoke cylinder, an electric heating assembly, a control assembly, a battery assembly and a main support. A pressure sensor is arranged on the side wall and the bottom of the smoke cylinder to monitor the insertion state of the aerosol generating assembly. Symmetrical insertion sensing parts such as protruding structures are arranged on the inner wall of the smoke cylinder as pressure sensing and triggering. When the aerosol generating assembly is inserted, the insertion sensing parts are deformed under pressure to trigger the sensor output. The pressure sensing of the side wall is used as a signal trigger, so that the second pressure sensor enters the working state from the low-power sleep or power-off state, and it is further judged whether the aerosol generating assembly is actually inserted and inserted in place, to avoid false detection. The control assembly activates the electric heating assembly accordingly, heats the inserted aerosol generating assembly, and promotes the generation of aerosol.

Description

Technical Field

[0001] This invention 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, control method, and 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 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. Summary of the Invention

[0005] In view of the technical problems existing in the prior art of portable aerosol generators based on electric heating, according to a first aspect of the present invention, a heating control device for an aerosol generator is provided, 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 function of the electric heating component;

[0009] The heating control device further includes:

[0010] A pair of first pressure sensors are installed on the outer wall surface of the chimney. The two first pressure sensors are symmetrically distributed with respect to the central axis of the channel. The first pressure sensors are set to monitor the pressure on the side of the chimney at a preset first sampling frequency, denoted as F1.

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

[0012] A second pressure sensor is installed at the bottom of the chimney;

[0013] The second pressure sensor is set to be in a non-working state by default, and in response to the output signal of the first pressure sensor, the second pressure sensor is controlled to switch to a working state and monitors the pressure on the bottom of the chimney according to a preset second sampling frequency, which is denoted as F2.

[0014] The control component activates the electric heating component to heat the inserted aerosol generating component based on the pressure F2 output by the second pressure sensor.

[0015] 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.

[0016] In conjunction with the heating control of the aerosol generator in the above embodiments, pressure sensors are installed on the side wall and bottom of the chimney to monitor the insertion status of the aerosol generating component. Based on the sensing results, the system intelligently determines whether the aerosol generating component has been effectively inserted and is in the correct position, avoiding false detections. Specifically, dual pressure sensors are symmetrically positioned on the outer wall of the chimney, and symmetrical insertion sensing parts, such as protruding structures, are provided on the inner wall of the chimney for pressure sensing and triggering. When the aerosol generating component is inserted, the insertion sensing part is deformed by pressure, triggering the sensor output. The pressure sensing from the side wall serves as a signal trigger, causing the second pressure sensor, which is in a low-power sleep or power-off state, to enter the working state. This further determines whether the aerosol generating component has been actually inserted and is in place. The control component then activates the electric heating component to heat the inserted aerosol generating component, promoting aerosol generation.

[0017] Therefore, the insertion of the tobacco cartridge is automatically detected by the first pressure sensor on the side wall of the chimney, which in turn controls the second pressure sensor at the bottom of the chimney to switch from a non-working state to a working state. On the one hand, the second pressure sensor is designed to be in a dormant or power-off state initially to reduce power consumption. The second pressure sensor is only activated to monitor the actual insertion and placement of the aerosol generating component when it is actually inserted into the channel from the chimney inlet and detected. On the other hand, this design avoids misjudgments caused by small or broken objects accidentally falling to the bottom of the chimney. When small or broken objects accidentally fall to the bottom of the chimney, the second pressure sensor is in a non-working state and will not trigger the control component to ignite the electric heating component, thus avoiding localized abnormal high temperatures caused by accidental heating and potential safety issues.

[0018] A second aspect of the invention also provides an aerosol generating apparatus, comprising:

[0019] Main support;

[0020] Battery components; and

[0021] Heating control device for the aerosol generator in the foregoing embodiments;

[0022] The chimney, electric heating component, control component, and battery component are all mounted on the main support.

[0023] The aerosol generator and its heating control device proposed in this invention can automatically sense and control the activation and ignition of the electric heating component, eliminating the need for a separate ignition control button, reducing false triggering and accidental heating, optimizing the lifespan and battery life of the portable aerosol generator, and improving user experience and safety. Furthermore, it eliminates the need for additional spring-like structures as triggering devices on the inner wall of the chimney, resulting in a more reliable structure.

[0024] Meanwhile, the design of reducing mechanical buttons on the surface of the aerosol generator of the present invention 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.

[0039] To better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0040] Various aspects of the invention are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily intended to encompass all aspects of the 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 invention disclosed may be used alone or in any suitable combination with other aspects of the invention disclosed.

[0041] {Example 1}

[0042] like Figure 1 , Figure 12 As shown, the aerosol generating device according to the present invention 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 100, which serves as an integral 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 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] In an embodiment of the present 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.

[0048] like Figures 1-5 As shown, in an embodiment of the present invention, a pair of first pressure sensors 101a are installed on the outer wall surface (110a) of the chimney, and the pair of pressure sensors 101a are symmetrically distributed with respect to the central axis of the channel 111. Each first pressure sensor 101a is configured to monitor the lateral pressure on the chimney 110 at a preset first sampling frequency f1, denoted as F1. In this embodiment, the first sampling frequency f1 is typically 50Hz.

[0049] 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, so that the aerosol generating component 200 can actuate the insertion sensing part 105 during the process of entering the channel 111, causing the insertion sensing part and / or sensing area to deform and trigger the output of the first pressure sensor 101a.

[0050] Combined with appendix Figure 1 , 4 As shown in Figures 5 and 12, in an embodiment of the present invention, a second pressure sensor 101b is also provided at the bottom of the chimney 110. The second pressure sensor 101b is set to a non-working state by default, for example, configured to a sleep state, or connected to the battery assembly via an electronic switch, and the second pressure sensor 101b is controlled to be in a power-off state by controlling the on / off state of the electronic switch.

[0051] In an embodiment of the present invention, in response to the output signal of the first pressure sensor 101a, the control component can control the second pressure sensor 101b to switch to the working state, for example, to be activated or powered on, and monitor the pressure on the bottom of the chimney 110 according to a preset second sampling frequency f2, denoted as F2.

[0052] In an optional embodiment, the second sampling frequency f2 can be configured to be the same as or different from the first sampling frequency f1, for example, a larger value than the first sampling frequency f1, to obtain a shorter sampling time period. In this embodiment, the second sampling frequency f2 is set to 50Hz.

[0053] Furthermore, the control component 130 controls the activation of the electric heating component 120 to heat the inserted aerosol generating component based on the pressure F2 output by the second pressure sensor 101b.

[0054] like Figures 2-5 As shown, in the first embodiment of the present invention, 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 selected as 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.

[0055] As an example, the aforementioned first pressure sensor 101a is respectively configured with an insertion sensing part 105, and the insertion sensing parts 105 on both sides are symmetrically distributed with respect to the central axis of the channel 111.

[0056] 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.

[0057] 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.

[0058] Combination Figures 2-5As shown, in an optional embodiment, the sensing area defined by the first pressure sensor 101a includes the projection area of ​​the area covered by the aforementioned pressure sensor at the mounting 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.

[0059] As an optional embodiment, the preset distance for downward extension is typically designed to be between 1 and 20 mm.

[0060] Therefore, the installation position of the insertion sensing part is optimized, staggered from the first pressure sensor 101a 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 by pressure and / or causes deformation of the sensing area. Such deformation is sensed by the sensor and triggers the sensor output.

[0061] In an optional embodiment, similar to the design of the first pressure sensor, a protruding structure can be designed at the bottom of the chimney 110 as a contact sensing part, which is set in the sensing area defined by the second pressure sensor 101b at the bottom, to optimize the sensing and transmission of bottom pressure.

[0062] In embodiments of the present invention, the aforementioned first pressure sensor 101a and second pressure sensor 101b are preferably 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 is particularly preferred, for example... The PMDS-F2 / F3 stress sensor enables high-precision digital sampling of pressure.

[0063] 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.

[0064] 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.

[0065] Combination Figures 9-11As 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 first pressure sensor 101a of the side wall.

[0066] 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.

[0067] In an optional embodiment, combined with Figure 12 As shown, the control component 130 can be a low-power microprocessor module, connected to the aforementioned first pressure sensor 101a, second pressure sensor 101b and electric heating component 120, and controls the activation and ignition of the electric heating component according to the output of the second pressure sensor 101b.

[0068] As an optional example, the control component 130 controls the second pressure sensor 101b to enter the working state and continuously monitor the pressure F2 at the bottom of the chimney 110 based on the pressure F1 output by any one of the pair of first pressure sensors 101a, and controls the activation of the electric heating component 120 to perform heating operation when the monitored pressure F2 exceeds a preset threshold.

[0069] Therefore, when the insertion of the aerosol generating component 120 is initially monitored by any of the first pressure sensors 101a set on the side wall of the chimney, and the first pressure sensor 101b is enabled to enter the working state accordingly, the control component determines that the aerosol generating component 120 is effectively inserted and inserted in place when the output of the second pressure sensor 101b is continuously monitored and a certain pressure threshold is reached, and then controls and activates the electric heating component 120 to perform heating operation.

[0070] As an optional example, during the heating process, the second pressure sensor 101b continuously monitors the pressure status, for example, continuously monitoring the pressure F2 at the bottom of the chimney 110 according to the preset third sampling frequency f3. When the pressure F2 monitored by the second pressure sensor 101b drops to a predetermined level, it is determined that the aerosol generating component 120 is pushed out from the channel 111. Then, the electric heating component 120 is controlled to stop heating, and the second pressure sensor 101b is controlled to switch to a non-working state.

[0071] {Example 2}

[0072] Combination Figures 1-12 The aerosol generator and its heating control design are shown. In this embodiment, the proposed heating control method for the aerosol generator includes the following steps:

[0073] S101, the first pressure sensor 1011 monitors the pressure on the side of the chimney 110 according to the preset first sampling frequency f1, and records it as F1; the second pressure sensor 101b is configured to be in a non-working state by default;

[0074] S102. When the pressure F1 output by any of the first pressure sensors 101a is detected, the second pressure sensor 101b is controlled to enter the working state and continuously monitors the pressure F2 at the bottom of the chimney 110 according to the preset second sampling frequency f2.

[0075] S103. In response to the monitoring pressure F2 exceeding the preset threshold, the electric heating component 120 is activated to perform heating operation.

[0076] S104. During the heating operation of the electric heating component 120, the second pressure sensor 101b continuously monitors the pressure F2 at the bottom of the chimney 110 according to the preset third sampling frequency f3.

[0077] S105. When the monitored pressure F2 drops to a predetermined level, the electric heating component 120 is controlled to stop heating, and the second pressure sensor 101b is switched to a non-working state.

[0078] As an optional implementation, the second sampling frequency f2 can be configured to be the same as or different from the first sampling frequency f1, for example, a larger value than the first sampling frequency f1, in order to obtain a shorter sampling time period.

[0079] In this embodiment, the first sampling frequency f1 and the second sampling frequency f2 are both 50Hz. The third sampling frequency f3 is specifically set to be lower than the second sampling frequency f2, so as to monitor the pressure status with a longer sampling time period.

[0080] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
