[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0048] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0049] References to "one embodiment", "some embodiments" or "an embodiment" described in the specification of this application mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some other embodiments", "in some other embodiments", etc., which appear at different places in this specification, do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. In addition, in one or more embodiments, particular features, structures or characteristics may be combined in any suitable manner.

[0050] In order to illustrate the technical solution of the present application, a description is given below in conjunction with specific drawings and embodiments.

[0051] In the related art, different solid aerosol substrates need to be heated using different heating temperature curves, otherwise the aerosol substrate will fail to generate aerosol or the aerosol will be overheated. Traditional aerosol generating devices cannot heat different aerosol substrates with corresponding heating temperature curves, and have poor versatility.

[0052] In view of this, the present application provides an aerosol generating device and a control method thereof. Since the shell assembly is provided with a receiving hole, and the pressure detecting element and the heating element assembly are both arranged inside the shell assembly, after the solid aerosol matrix is ​​placed in the receiving hole, the aerosol matrix located in the receiving hole can apply pressure to the pressure detecting element, and the pressure detecting element can detect the pressure applied by the aerosol matrix to the pressure detecting element, and the heating element assembly can heat the aerosol matrix according to the pressure detected by the pressure detecting element.

[0053] Since the pressures applied by the aerosol substrates of different hardness to the pressure detection part are different, the pressures applied by the aerosol substrates detected by the pressure detection part to the pressure detection part are also different, so the heating element assembly can be used to heat the aerosol substrate in a targeted manner according to the pressure detected by the pressure detection part, and the versatility is better. The aerosol generating device provided by the present application can improve the problem that the traditional aerosol generating device cannot heat the aerosol substrates of different hardness in a targeted manner and has poor versatility.

[0054] Please refer to Figures 1 to 4 , Figure 1 is a schematic diagram of the structure of an aerosol generating device 100 and an aerosol substrate 200 in one embodiment of the present application. Figure 2 yes Figure 1 The aerosol generating device 100 and the aerosol substrate 200 are shown in a left side view. Figure 3 yes Figure 2 The cross-sectional view of the aerosol generating device 100 and the aerosol substrate 200 along the MM direction is shown. Figure 4 yes Figure 3 A partial enlarged view of point A in the middle.

[0055] The embodiment of the present application provides an aerosol generating device 100 , including a housing assembly 10 , a pressure detecting component 20 and a heating element assembly 30 .

[0056] The housing assembly 10 is provided with a receiving hole 101 , and the receiving hole 101 is used to receive the solid aerosol matrix 200 .

[0057] The aerosol substrate 200 may be in a rod shape or a strip shape, etc. The aerosol substrate 200 can be inserted into the receiving hole 101 .

[0058] The pressure detection member 20 is disposed inside the housing assembly 10 . The aerosol matrix 200 in the receiving hole 101 can apply pressure to the pressure detection member 20 . The pressure detection member 20 is used to detect the pressure applied by the aerosol matrix 200 to the pressure detection member 20 .

[0059] The pressure detection element 20 may be in direct or indirect contact with the aerosol matrix 200. The pressure detection element 20 may be a pressure sensor, such as a resistive pressure sensor, a capacitive pressure sensor, or a piezoelectric pressure sensor.

[0060] The heating element assembly 30 is disposed inside the housing assembly 10 , and the heating element assembly 30 is used to heat the aerosol substrate 200 according to the pressure applied by the aerosol substrate 200 to the pressure detecting element 20 .

[0061] The heating element assembly 30 can heat the aerosol matrix 200 by central heating, circumferential heating, airflow heating, etc. The heating element assembly 30 can include a resistive heating element, an electromagnetic induction heating element, an infrared heating element, etc.

[0062] Please refer to Figure 5 , the control method of the aerosol generating device 100 provided in the embodiment of the present application includes:

[0063] S100 : Obtaining the pressure exerted by the aerosol matrix 200 on the pressure detection member 20 .

[0064] Specifically, the aerosol substrate 200 may be inserted into the accommodating hole 101 , and the pressure detecting member 20 may be used to detect the pressure applied by the aerosol substrate 200 to the pressure detecting member 20 .

[0065] Specifically, the aerosol substrates 200 of different hardness exert different pressures on the pressure detecting member 20 .

[0066] For example, since the paper tube of the particle-type aerosol matrix 200 is relatively hard, the pressure felt by the pressure detection element 20 after being inserted into the accommodating hole 101 is relatively large, and at this time, the pressure value output by the pressure detection element 20 is relatively large.

[0067] After the sheet-type aerosol substrate 200 is inserted into the accommodating hole 101 , the pressure value output by the pressure detecting element 20 is relatively small because the paper tube of the sheet-type aerosol substrate 200 is relatively soft.

[0068] S200: Controlling the heating element assembly 30 to heat the aerosol matrix 200 according to the pressure.

[0069] Specifically, since the aerosol substrates 200 of different hardness exert different pressures on the pressure detection element 20, the heating element assembly 30 can be controlled to heat the aerosol substrate 200 in a targeted manner according to the pressure detected by the pressure detection element 20, which has better versatility.

[0070] From the above, it can be seen that the aerosol generating device 100 and the control method thereof provided by the present application, since the shell component 10 is provided with a receiving hole 101, and the pressure detection component 20 and the heating element component 30 are both arranged inside the shell component 10, after the solid aerosol matrix 200 is placed in the receiving hole, the aerosol matrix 200 located in the receiving hole 101 can apply pressure to the pressure detection component 20, and the pressure detection component 20 can detect the pressure applied by the aerosol matrix 200 to the pressure detection component 20, and the heating element component 30 can heat the aerosol matrix 200 according to the pressure detected by the pressure detection component 20.

[0071] Since the pressures applied by the aerosol substrates 200 of different hardness to the pressure detection element 20 are different, the pressures applied by the aerosol substrates 200 detected by the pressure detection element 20 to the pressure detection element 20 are also different, so the heating element assembly 30 can be used to heat the aerosol substrate 200 in a targeted manner according to the pressure detected by the pressure detection element 20, and the versatility is better. The aerosol generating device 100 provided in the present application can improve the problem that the conventional aerosol generating device 100 cannot heat the aerosol substrates 200 of different hardness in a targeted manner and has poor versatility.

[0072] The heating element assembly 30 is controlled according to the pressure to heat the aerosol matrix 200, including:

[0073] First, obtain the heating temperature curve corresponding to the pressure.

[0074] Next, the heating element assembly 30 is controlled to heat the aerosol matrix 200 according to the heating temperature curve.

[0075] By adopting the above solution, the heating element assembly 30 can be controlled to heat the aerosol matrix 200 with different heating temperature curves according to the pressure detected by the pressure detection element 20, and the versatility is good.

[0076] In order to avoid the possibility that the same type of aerosol substrate 200 may apply different pressures to the pressure detection element 20 due to the assembly error of the aerosol generating device 100 and the hardness error of the aerosol substrate 200, resulting in the inability to specifically control the heating element assembly 30 to heat the aerosol substrate 200 according to the pressure, optionally, obtaining a heating temperature curve corresponding to the pressure includes:

[0077] According to the pre-stored multiple pressure intervals and multiple heating temperature curves, a heating temperature curve corresponding to the pressure interval is obtained, wherein one pressure interval corresponds to one heating temperature curve.

[0078] By adopting the above solution, the heating element assembly 30 can be controlled to heat the aerosol substrate 200 according to the same heating temperature curve for the same type of aerosol substrate 200, thereby avoiding the influence caused by the assembly error of the aerosol generating device 100 and the hardness error of the aerosol substrate 200. In addition, it is not necessary to set a corresponding heating temperature curve for each pressure, which is also convenient for manufacturing the aerosol generating device 100.

[0079] For example, two pressure intervals and two heating temperature curves are pre-stored, and the two heating temperature curves are heating temperature curve No. 1 and heating temperature curve No. 2. When the particle-type aerosol substrate 200 is inserted into the receiving hole 101, the heating element assembly 30 is controlled to heat the aerosol substrate 200 according to heating temperature curve No. 1, and the heating is stopped when the time or the number of puffs reaches a preset value; when the sheet-type aerosol substrate 200 is inserted into the receiving hole 101, the heating element assembly 30 is controlled to heat the aerosol substrate 200 according to heating temperature curve No. 2, and the heating is stopped when the time or the number of puffs reaches a preset value.

[0080] In this embodiment, the aerosol generating device 100 further includes a control component, and the heating element component 30 and the pressure detecting component 20 are both electrically connected to the control component.

[0081] By adopting the above scheme, the control component can be used to receive the pressure applied by the aerosol matrix 200 to the pressure detection component 20 detected by the pressure detection component 20, and the heating element component 30 can be controlled to heat the aerosol matrix 200 in a targeted manner according to the pressure applied by the aerosol matrix 200 to the pressure detection component 20 detected by the pressure detection component 20.

[0082] It should be noted that a start switch may be electrically connected to the control component. After the start switch is turned on, the control component receives a start heating signal, and then uses the control component to receive the pressure applied to the pressure detection component 20 by the aerosol matrix 200 detected by the pressure detection component 20.

[0083] Optionally, the control component includes an electrically connected controller and a memory, the heating element component 30 and the pressure detection component 20 are both electrically connected to the controller, and a plurality of heating temperature curves are stored in the memory.

[0084] Optionally, the control assembly includes a circuit board 50 and a power supply 60 which are electrically connected, and the controller and the memory are both arranged on the circuit board 50. Such an arrangement can make the structure of the control assembly more compact.

[0085] Please refer to Figures 6 to 9 , Figure 6 yes Figure 3 The schematic diagram of the structure of the first shell 11, the pressure detection member 20 and the clamping member 40 in the aerosol generating device 100 shown in FIG. Figure 7 yes Figure 6 The exploded structural diagram of the first housing 11, the pressure detection member 20 and the clamping member 40 is shown in FIG. Figure 8 yes Figure 6 The front view of the first housing 11, the pressure detection member 20 and the clamping member 40 is shown, Fig. 9 yes Figure 8 The cross-sectional view of the first housing 11, the pressure detecting member 20 and the clamping member 40 along the NN direction is shown.

[0086] In this embodiment, the aerosol generating device 100 also includes a clamping member 40, which is disposed inside the accommodating hole 101, and is used to be sleeved on the aerosol matrix 200; the clamping member 40 is abutted against the aerosol matrix 200, and the side of the clamping member 40 facing away from the aerosol matrix 200 is abutted against the pressure detecting member 20, and the aerosol matrix 200 can apply pressure to the pressure detecting member 20 through the clamping member 40.

[0087] By adopting the above scheme, not only can the clamping member 40 be used to limit the aerosol matrix 200 to prevent the aerosol matrix 200 from shaking or moving significantly in the accommodating hole 101, but the clamping member 40 can also be used to separate the internal space of the accommodating hole 101 from the pressure detecting member 20, thereby preventing the aerosol matrix 200 from being in contact with the pressure detecting member 20 after being heated by the heating element assembly 30 according to pressure, thereby preventing the performance of the pressure detecting member 20 from being affected.

[0088] It is understandable that the pressure detection member 20 has a certain degree of deformability. After the aerosol matrix 200 contacts the clamping member 40, it will apply pressure to the clamping member 40, and the clamping member 40 continues to apply pressure to the pressure detection member 20, thereby achieving the aerosol matrix 200 applying pressure to the pressure detection member 20 through the clamping member 40.

[0089] It should be noted that the pressure applied by the aerosol matrix 200 to the clamping member 40 and the pressure applied by the clamping member 40 to the pressure detecting member 20 are in a one-to-one correspondence, and this relationship can be obtained by using the aerosol matrix 200 to press against the clamping member 40 at different pressures in advance, and then detecting the corresponding pressure detected by the pressure detecting member 20. Therefore, the pressure detecting member 20 can detect the pressure applied by the aerosol matrix 200 to the pressure detecting member 20 by detecting the pressure applied by the clamping member 40 to the pressure detecting member 20.

[0090] For example, the material of the pressure detection element 20 may be silicone, rubber, or plastic.

[0091] Optionally, the clamp 40 is annular in shape, and a protrusion 41 is provided on the inner wall of the clamp 40 . The protrusion 41 is used to abut against the aerosol matrix 200 , and a side of the clamp 40 away from the protrusion 41 abuts against the pressure detection member 20 .

[0092] With such arrangement, the protrusion 41 can be used to better limit the position of the aerosol matrix 200 , and the side of the clamping member 40 away from the protrusion 41 is more likely to deform, thereby making it easier for the pressure detection member 20 to detect pressure.

[0093] Optionally, the outer wall of the clamp 40 is provided with a recessed portion 42 , which extends along the circumference of the clamp 40 , the raised portion 41 is provided correspondingly to part of the recessed portion 42 , and the pressure detecting member 20 shields the recessed portion 42 in the axial direction of the clamp 40 .

[0094] With such an arrangement, after the clamping member 40 and the aerosol matrix 200 are abutted against each other, the side of the clamping member 40 that is away from the aerosol matrix 200 can be deformed more easily, so that after the clamping member 40 and the pressure detecting member 20 are abutted against each other, the pressure detecting member 20 can more accurately detect the pressure applied by the clamping member 40 to the pressure detecting member 20, that is, more accurately detect the pressure applied by the aerosol matrix 200 to the pressure detecting member 20.

[0095] Optionally, the protrusion 41 is provided with a guiding slope 43, which is provided on the side of the protrusion 41 away from the bottom of the accommodating hole 101, and the guiding slope 43 is used to guide the aerosol matrix 200 to move towards the axis of the clamping member 40 after contacting the aerosol matrix 200.

[0096] Such a configuration can facilitate the insertion of the aerosol matrix 200 into the interior of the clamping member 40 .

[0097] Optionally, a plurality of protrusions 41 are provided, and the plurality of protrusions 41 are spaced apart along the circumference of the clamping member 40 , and a side of the clamping member 40 away from one of the protrusions 41 abuts against the pressure detecting member 20 .

[0098] Such a configuration can not only use the protrusion 41 to better limit the aerosol matrix 200, but also avoid excessive friction on the aerosol matrix 200 during the process of inserting the aerosol matrix 200 into the interior of the clamp 40, resulting in excessive force required to insert the aerosol matrix 200 into the interior of the clamp 40.

[0099] In other embodiments, at least a portion of the pressure detection member 20 is located inside the receiving hole 101 and is used to contact the aerosol matrix 200 .

[0100] By adopting the above solution, the pressure detecting member 20 can be used to directly detect the pressure applied by the aerosol matrix 200 to the pressure detecting member 20 , thereby improving the accuracy of the detection result of the pressure detecting member 20 .

[0102] By adopting the above solution, the housing assembly 10 is divided into two parts, which can facilitate the production of the housing assembly 10 and facilitate the placement of the heating element assembly 30 in the second hole 120 .

[0103] Optionally, in the insertion direction of the aerosol substrate 200 , the aperture of the first hole 110 gradually decreases, and the inner wall surface of the second hole 120 fits with the aerosol substrate 200 .

[0104] By adopting the above solution, the aerosol substrate 200 can be conveniently inserted into the first hole 110 and then inserted into the second hole 120 from the first hole 110 , and the aerosol substrate 200 can be better limited by the inner wall of the second hole 120 .

[0105] For example, the insertion direction of the aerosol substrate 200 may be Figure 3 The direction indicated by the arrow S.

[0106] Optionally, the clamping member 40 is disposed in the first hole 110 , the first shell 11 is provided with an avoidance hole 111 , and part of the pressure detecting member 20 extends into the avoidance hole 111 and abuts against the clamping member 40 .

[0107] Such an arrangement makes it easy to set the position of the pressure detection member 20.

[0108] Optionally, the housing assembly 10 further includes a third housing 13 , and the third housing 13 is provided with a mounting hole 130 , into which the second housing 12 and the first housing 11 are sequentially inserted.

[0109] By adopting the above solution, the relative positions of the first shell 11 and the second shell 12 are conveniently fixed.

[0110] Among them, the inner wall of the mounting hole 130 is provided with a stop flange 131, the second shell 12 includes a main body 121 and a limit portion 122 connected to each other, the second hole 120 is provided in the main body 121, and the main body 121 is inserted into the interior of the stop flange 131 so that the limit portion 122 is abutted against the stop flange 131, and the side of the limit portion 122 away from the stop flange 131 is abutted against the first shell 11.

[0111] With such arrangement, the position of the second shell 12 can be limited by the stop flange 131 and the first shell 11 , and the assembly is simple and convenient.

[0112] Optionally, the housing assembly 10 further includes an outer housing 14 , and the first housing 11 , the second housing 12 , the third housing 13 , the pressure detection element 20 , the heating element assembly 30 and the control assembly are all disposed in the outer housing 14 .
