[0001] The present application relates to the field of heat-without-burning atomizing devices, and in particular to a heat-without-burning atomizing device and a control method and a control device thereof. Background Art

[0002] The heat-not-burn atomizer heats the object to be heated so that it is atomized to form an aerosol. Common heat-not-burn atomizers use built-in electric heating elements to accurately heat a special aerosol matrix to a specific temperature so that part of the substance in the aerosol matrix evaporates, but it does not reach the level of combustion.

[0003] The aerosol matrix is ​​usually contained in an atomizer, and different atomizers can usually contain different types of aerosol matrices. When using the heat-not-burn atomizer device, the user can select a suitable atomizer to connect to the heat-not-burn atomizer device according to personal preference.

[0004] When the user connects the atomizer to the heat-not-burn atomizer device, due to the assembly precision, structure and size differences between different atomizers, the heated part of the atomizer and the heating element in the heat-not-burn atomizer device may not be directly aligned, but there may be a certain deviation, so that the heating effect of the heating element on the atomizer is inconsistent with expectations, thereby affecting the atomization effect. Summary of the invention

[0006] In a first aspect, an embodiment of the present application provides a control method for a heat-not-burn atomization device, the control method for a heat-not-burn atomization device comprising:

[0007] The heating power of the heating element of the heat-not-burn atomizing device is controlled based on the depth of insertion of the atomizer into the heat-not-burn atomizing device.

[0008] In some examples, controlling the heating power of the heating element of the heat-not-burn atomization device based on the depth of the atomizer inserted into the heat-not-burn atomization device includes:

[0015] In some examples, determining the heating power of the heating element includes at least one of the following:

[0016] If the depth of the atomizer inserted into the heat-not-burn atomizer device represented by the position indication information is equal to the reference depth, the preset reference power is used as the heating power of the heating element;

[0017] If the depth of the atomizer inserted into the heat-not-burn atomizer device represented by the position indication information is greater than the reference depth, a power less than the preset reference power is used as the heating power of the heating element;

[0018] If the depth of the atomizer inserted into the heat-not-burn atomizer device represented by the position indication information is less than the reference depth, a power greater than the preset reference power is used as the heating power of the heating element;

[0019] If the depth of the atomizer inserted into the heat-not-burn atomizer device represented by the position indication information differs from the reference depth by more than a preset threshold, it is determined that the heating power of the heating element is 0.

[0020] In some examples, there is a positive correlation between the difference between the heating power of the heating element and the preset reference power, and the difference between the depth of the atomizer inserted into the heat-not-burn atomization device represented by the position indication information and the reference depth.

[0021] In some examples, the absolute value of the difference between the heating power of the heating element and the preset reference power, and the absolute value of the difference between the depth of the atomizer inserted into the heat-not-burn atomization device represented by the position indication information and the reference depth are proportional.

[0022] In some examples, determining the heating power of the heating element based on the position indication information includes:

[0023] The heating power of the heating element is determined based on a minimum difference between a depth of the atomizer inserted into the heat-not-burn atomization device represented by the position indication information and a plurality of different reference depths.

[0024] In a second aspect, an embodiment of the present application also provides a control device for a heat-not-burn atomization device, which is used to be electrically connected to a heating element of the heat-not-burn atomization device, and is used to control the heating power of the heating element of the heat-not-burn atomization device based on the depth of insertion of the atomizer into the heat-not-burn atomization device.

[0029] By controlling the heating power of the heating element of the heat-not-burn atomizer device based on the depth to which the atomizer is inserted into the heat-not-burn atomizer device, the heating power of the heating element can be changed according to the depth to which the atomizer is inserted into the heat-not-burn atomizer device, rather than heating at a fixed heating power, thereby reducing the deviation of the heating effect from the expected value, which is beneficial to improving the atomization effect.

[0046] In order to better understand the present application, the structure of the heating without burning atomization device is first described below.

[0047] Figure 1 Schematic diagram of a heat-without-burning atomization device provided in an embodiment of the present application. Figure 1 As shown, the heat-not-burn atomizer device comprises a main body 10. The main body 10 has a slot 10a for accommodating an atomizer.

[0048] Figure 2 Schematic diagram of the internal structure of a heat-not-burn atomization device provided in an embodiment of the present application. Figure 2 As shown, the heat-not-burn atomizing device further includes a lifting structure 20 and a heating element 32. The lifting structure 20 is at least partially located at the bottom of the slot 10a, and the portion of the lifting structure 20 located at the bottom of the slot can move along the depth direction of the slot 10a, so that the slot 10a matches the atomizer 100. The heating element 32 is located in the main body 10, and the heating element 32 is used to heat the atomizer 100.

[0049] For ease of explanation, Figure 2Also shown is an atomizer 100. During use, at least a portion of the atomizer 100 is inserted into the slot 10a.

[0050] In the embodiment of the present application, the slot 10a matches the atomizer 100, including at least the following two scenarios:

[0051] Scenario 1: For the same atomizer 100

[0052] When the atomizer 100 is connected to the heat-not-burn atomizer device, due to operational reasons or product dimensional accuracy, after the atomizer 100 is inserted into the slot 10a, the relative position relationship between the heated portion of the atomizer 100 and the heating element 32 may differ from the most ideal relative position relationship. Figure 3 It is a comparative schematic diagram of the relative position relationship between an atomizer and a heating element provided in an embodiment of the present application. The dotted box in the figure shows the part of the atomizer 100 used for heating, and the part of the atomizer 100 used for heating in the middle is in the most ideal position. However, in actual operation, the part of the atomizer 100 used for heating may be located at A or B in the figure, where A is higher and B is lower. For the heating-not-burning atomizing device in this example, since a lifting structure 20 is provided, the depth of the atomizer 100 inserted into the slot 10a can be adjusted by moving the part of the lifting structure 20 located at the bottom of the slot along the depth direction of the slot 10a, that is, changing the relative position of the part of the atomizer 100 used for heating and the heating element 32, so that the slot 10a matches the atomizer 100.

[0053] Scenario 2: For different atomizers 100

[0054] Since different atomizers 100 may have different lengths or different positions for being heated, the length of the atomizer 100 that needs to be inserted into the slot 10a during use may be different. Since the lifting structure 20 is at least partially located at the bottom of the slot 10a, the distance from the part of the lifting structure 20 located at the bottom of the slot 10a to the opening of the slot 10a is the length of the atomizer 100 that the slot 10a can accommodate. Since the part of the lifting structure 20 located at the bottom of the slot can move along the depth direction of the slot 10a, the part of the lifting structure 20 located at the bottom of the slot is located at different positions of the slot 10a, and the length of the atomizer 100 that the slot 10a can accommodate is also different. By adjusting the position of the part of the lifting structure 20 located at the bottom of the slot in the slot 10a, the length of the atomizer 100 that the slot 10a can accommodate can be made consistent with the length of the atomizer 100 that needs to be inserted into the slot 10a, so that the slot 10a matches the atomizer 100.

[0055] In the embodiment of the present application, the heating element 32 is configured to provide at least two heating modes based on the position of the portion of the lifting structure 20 located at the bottom of the slot in the slot 10 a.

[0056] In an embodiment of the present application, the heating method may include at least one factor, which may be the heating power. In addition, the heating power may also include at least one of the following factors: the change of heating power with heating time and the heating time.

[0057] There is at least one factor that is different between the two heating methods, and the heating methods with the same factors are the same heating method. For example, one heating method may be continuous heating at a first power, the magnitude of the first power is constant, and the other heating method may be continuous heating at a second power, the magnitude of the second power is constant, and the magnitude of the second power is different from the magnitude of the first power.

[0058] The heating power referred to in the embodiments of the present application may refer to constant power in the example of constant power heating; for the example of variable power heating, that is, the power changes with time during the heating time period, the heating power may be the power at any time during the heating time period.

[0059] By setting a lifting structure 20 in the main body 10 of the heat-not-burn atomizer device, the lifting structure 20 is at least partially located at the bottom of the slot 10a of the main body 10, and the part can also move along the depth direction of the slot 10a, so that the slot 10a can match different atomizers 100. By setting a heating element 32 in the main body 10 of the heat-not-burn atomizer device, the heating element 32 can provide at least two heating methods based on the position of the part of the lifting structure 20 located at the bottom of the slot 10a in the slot 10a. That is, when the part of the lifting structure 20 located at the bottom of the slot 10a is at one position in the slot 10a, the heating element 32 can provide a heating method to heat the atomizer 100; when the part of the lifting structure 20 located at the bottom of the slot 10a is at another position in the slot 10a, the heating element 32 can provide another heating method to heat the atomizer 100. This enables the heat-not-burn atomizer device to provide at least two different heating methods according to the different depths of the atomizer 100 inserted into the heat-not-burn atomizer device when using the same atomizer 100. For different atomizers 100, the heat-without-burning atomization device can at least adapt to two different atomizers 100 and provide corresponding heating methods to produce a better atomization effect.

[0060] In some examples, the heating element 32 can be configured to provide three or more heating methods based on at least a portion of its position within the slot 10a, so that the heat-not-burn atomization device can be adapted to more different atomizers 100, and provide a richer adjustment of the heating methods when using the same atomizer 100, so that the heating effect can better meet the requirements and improve the atomization effect.

[0061] like Figure 2 As shown, the heat-not-burn atomizer device further includes a control device 31. The control device 31 is used to be electrically connected to a heating element 32 of the heat-not-burn atomizer device. In this example, the control device 31 is used to control the heating power of the heating element 32 of the heat-not-burn atomizer device based on the depth of the atomizer 100 inserted into the heat-not-burn atomizer device.

[0062] By controlling the heating power of the heating element 32 of the heat-not-burn atomization device based on the depth at which the atomizer 100 is inserted into the heat-not-burn atomization device, the heating power of the heating element 32 can be changed according to the depth at which the atomizer 100 is inserted into the heat-not-burn atomization device, rather than heating at a fixed heating power, thereby reducing the deviation of the heating effect from the expected value, which is beneficial to improving the atomization effect.

[0063] Combination Figure 3 As shown, when the heated portion of the atomizer 100 is located at A or B in the figure, the aerosol matrix contained in the heated portion of the atomizer 100 is heated at different locations. When it is at A, the bottom of the aerosol matrix is ​​heated, and when it is at B, the top of the aerosol matrix is ​​heated, so that the atomization effect does not meet the requirements. In the embodiment of the present application, the heating power of the heating element 32 is adjusted to improve the atomization effect.

[0064] In this example, the control device 31 is located at one side of the lifting structure 20 , and the control device 31 cooperates with the lifting structure 20 to control the heating mode of the heating element 32 .

[0065] The lifting structure 20 is at least partially located in the slot 10a, and the change of the lifting structure 20 can reflect the length of the atomizer 100 that the slot 10a can accommodate. The control device 31 cooperates with the lifting structure 20 to control the heating mode of the heating element 32, so that the heating mode can form a corresponding relationship with the length of the atomizer 100 that the slot 10a can accommodate, so that the heating mode can be matched with different atomizers.

[0066] like Figure 2As shown, the control device 31 includes a distance sensor 311 and a control board 312. The distance sensor 311 and the heating element 32 are electrically connected to the control board 312 respectively, and the sensing part of the distance sensor 311 faces the lifting structure 20. The control board 312 is configured to control the heating mode of the heating element 32 based on the detection result of the distance sensor 311.

[0067] Illustratively, the control board 312 may be a printed circuit board or a flexible printed circuit board.

[0068] Since at least part of the lifting structure 20 can move along the depth direction of the slot 10a, the lifting structure 20 is movable. The sensing part of the distance sensor 311 is directed toward the lifting structure 20, and the distance sensor 311 is used to detect the distance between the sensing part of the distance sensor 311 and the lifting structure 20, so as to control the heating mode according to the distance between the sensing part of the distance sensor 311 and the lifting structure 20, so that the heating mode matches the position of the part of the lifting structure 20 located in the slot 10a in the slot 10a.

[0069] In some examples, the lifting structure 20 includes a moving member 21 and a rotating member 22. The moving member 21 is at least partially located in the slot 10a, and the rotating member 22 is rotatably arranged in the main body 10. The rotating member 22 is transmission-connected to the moving member 21 to drive the moving member 21 to move along the depth direction of the slot 10a by rotating.

[0070] The length of the atomizer 100 that the slot 10a can accommodate is adjusted by the movement of the moving member 21 in the slot 10a. The rotation of the rotating member 22 is converted into the translation of the moving member 21, so that the overall structure of the lifting structure 20 is more compact and occupies less space.

[0071] Figure 4 Schematic diagram of a lifting structure provided in an embodiment of the present application. Figure 4 As shown, in the lifting structure, the rotating member 22 includes a first tube body 221, and the moving member 21 includes a second tube body 211. The first tube body 221 and the second tube body 211 are coaxial and arranged along the depth direction of the slot 10a. The second tube body 211 is sleeved with the first tube body 221 to move along the depth direction of the slot 10a under the rotation of the first tube body 221.

[0072] In this example, the second tube 211 can be slidably matched with the main body 10, and the second tube 211 can slide along the depth direction of the slot 10a. One end of the second tube 211 is sleeved outside the first tube 221, and the first tube 221 drives the second tube 211 to move along the depth direction of the slot 10a by self-rotation.

[0073] like Figure 2As shown, the main body 10 may include a housing 11 and a mounting tube 12 located inside the housing 11, the opening of the slot 10a is located on the housing 11, one end of the mounting tube 12 is opposite to the opening, and the inner wall of the mounting tube 12 surrounds the slot 10a. The heating element 32 may be located on the outer wall of the mounting tube 12. In some examples, the heating element 32 may also be embedded in the wall of the mounting tube 12, or located on the inner wall of the mounting tube 12, as long as the atomizer 100 located in the slot 10a can be heated.

[0074] The second tube body 211 may be partially located in the installation tube 12 and slidably cooperate with the installation tube 12. Exemplarily, the inner wall of the installation tube 12 may have a guide groove, and the outer wall of the second tube body 211 may be connected to a slider 2111, and the slider 2111 is located in the guide groove. Through the cooperation between the slider 2111 and the guide groove, the movement of the second tube body 211 is limited to translation along the depth direction of the slot 10a.

[0075] As an example, Figure 4 As shown, the tube wall of the second tube body 211 may have a driving groove 211a, and the driving groove 211a may extend spirally along the axial direction of the second tube body 211. The outer side wall of the first tube body 221 may be connected to a driving shaft 2211, and the driving shaft 2211 is located in the driving groove 211a. During the rotation of the first tube body 221, the driving shaft 2211 abuts against the side wall of the driving groove 211a and moves in the driving groove 211a. The squeezing effect of the driving shaft 2211 on the side wall of the driving groove 211a pushes the second tube body 211 to move.

[0076] In other examples, the arrangement positions of the driving groove 211 a and the driving shaft 2211 may also be interchanged. For example, the driving groove 211 a is arranged on the tube wall of the first tube body 221 , and the driving shaft 2211 is arranged on the tube wall of the second tube body 211 .

[0077] In other possible implementations, one end of the first tube body 221 may be sleeved outside the second tube body 211 .

[0078] like Figure 4 As shown, the moving member 21 may further include a lifting platform 212, which is located in the slot 10a and connected to an end of the second tube 211 away from the first tube 221. The lifting platform 212 is used to support the atomizer 100.

[0079] In this example, the rotating member 22 further includes a shielding ring 222 . The shielding ring 222 is sleeved outside the first tube body 221 and connected to the first tube body 221 . Figure 5 is a partial structural schematic diagram of a heat-without-burning atomization device provided in an embodiment of the present application, such as Figure 5As shown, the sensing portion of the distance sensor 311 faces the outer side wall of the shielding ring 222 .

[0080] Within the rotation angle range of the rotating member 22 , the distance between the outer wall of the shielding ring 222 and the sensing part of the distance sensor 311 is different when the rotating member 22 is in the first angle state and the second angle state.

[0081] The rotating member 22 drives the moving member 21 to move by rotating itself, and the moving member 21 moves at different distances depending on the angle of rotation of the rotating member 22. In other words, there is a corresponding relationship between the angle of rotation of the rotating member 22 and the distance of movement of the moving member 21; and there is a corresponding relationship between the angle of rotation of the rotating member 22 and the position of the moving member 21 in the slot 10a.

[0082] The angular state of the rotating member 22 refers to the state of the rotating member 22 after it rotates a certain angle relative to the reference state. For example, if the angular state of the rotating member 22 is 10°, it means that the rotating member 22 is in a state of rotating 10° in the positive direction relative to the reference state; if the angular state of the rotating member 22 is -15°, it means that the rotating member 22 is in a state of rotating 15° in the negative direction relative to the reference state. The rotating member 22 can rotate in two directions, and any one of the two directions can be used as the positive direction and the other as the negative direction.

[0083] Any state of the rotating member 22 can be used as the reference state. For example, the state of the rotating member 22 when the distance between the moving member 21 and the opening of the slot 10a is the maximum can be used as the reference state.

[0084] In this example, the first angle state and the second angle state are two different angle states, that is, the first angle state rotates at a different angle than the reference state and the second angle state rotates at a different angle than the reference state. One of the first angle state and the second angle state may also be the reference state.

[0085] Since the distance between the outer wall of the shielding ring 222 and the sensing part of the distance sensor 311 is different in the first angle state and the second angle state of the rotating member 22 within the rotation angle range of the rotating member 22, the angle state of the rotating member 22 can be determined according to the distance between the outer wall of the shielding ring 222 and the sensing part of the distance sensor 311 detected by the distance sensor 311, and the position of the moving member 21 in the slot 10a can also be determined. It can be seen that there is a corresponding relationship between the angle state of the rotating member 22 and the atomizer 100 that the slot 10a can accommodate, and by rotating the rotating member 22 to different angle states, the slot 10a can accommodate different atomizers 100. The control board 312 controls the heating mode of the heating element 32 based on the detection result of the distance sensor 311. That is to say, when the angle state of the rotating element 22 is changed so that the slot 10a can accommodate another atomizer 100, the heating mode of the heating element 32 will also change accordingly, so that the heat-not-burn atomization device can not only be connected to different atomizers 100, but also after changing the connected atomizer 100, the heating mode can be changed for the atomizer 100, so that the heating mode can be more matched with the atomizer 100, thereby improving the atomization effect.

[0086] In some examples, the outer sidewall of the blocking ring 222 is a non-cylindrical surface.

[0087] Since the outer wall of the shielding ring 222 is a non-cylindrical surface, the distance from the sensing part of the distance sensor 311 to the outer wall of the shielding ring 222 will change during the rotation of the shielding ring 222.

[0088] like Figure 5 As shown, the outer side wall of the shielding ring 222 is a spiral surface.

[0089] For the spiral surface, during the process of the shielding ring 222 rotating in one direction, the distance between the outer wall of the shielding ring 222 and the sensing part of the distance sensor 311 will continuously change, gradually increasing or gradually decreasing. In this way, it is convenient for the control board 312 to control the heating element 32 to work in one heating mode when the distance between the outer wall of the shielding ring 222 and the sensing part of the distance sensor 311 is in a certain range, and to control the heating element 32 to work in another heating mode when the distance between the outer wall of the shielding ring 222 and the sensing part of the distance sensor 311 is in another range.

[0090] Exemplarily, when the distance between the outer wall of the shielding ring 222 and the sensing part of the distance sensor 311 is 95% to 105% of the reference distance, the heating element 32 is controlled to work in the first heating mode; when the distance between the outer wall of the shielding ring 222 and the sensing part of the distance sensor 311 is 70% to 95% of the reference distance, the heating element 32 is controlled to work in the second heating mode; when the distance between the outer wall of the shielding ring 222 and the sensing part of the distance sensor 311 is 105% to 130% of the reference distance, the heating element 32 is controlled to work in the third heating mode; the first heating mode, the second heating mode and the third heating mode are three different heating modes, and the reference distance is the distance between the outer wall of the shielding ring 222 and the sensing part of the distance sensor 311 when the rotating element 22 is in the reference state.

[0091] In some other possible implementations, the outer side wall of the shielding ring 222 may also be a cylindrical surface, and the axis of the cylindrical surface does not coincide with the rotation axis of the rotating member 22 .

[0092] That is to say, the shielding ring 222 may be an eccentric structure, and during the rotation of the rotating member 22, even if the outer wall of the shielding ring 222 is a cylindrical surface, the distance between the outer wall of the shielding ring 222 and the sensing part of the distance sensor 311 will change continuously.

[0093] In this example, there is a gap between the inner wall of the shielding ring 222 and the outer wall of the first tube body 221. In other possible implementations, there may be no gap between the inner wall of the shielding ring 222 and the outer wall of the first tube body 221; or, the shielding ring 222 may be an integral structure with the first tube body 221, that is, the outer wall of the shielding ring 222 may be a part of the outer wall of the first tube body 221.

[0094] like Figure 5 As shown, the end of the first tube 221 away from the moving member 21 has an outer flange 2212, and the outer edge of the outer flange 2212 has a limiting notch 2212a. The main body 10 has a limiting block 111, and the limiting block 111 is located in the limiting notch 2212a.

[0095] The limiting notch 2212 a cooperates with the limiting block 111 to limit the rotation angle range of the rotating member 22 .

[0096] When the stopper 111 contacts one side of the stopper notch 2212a, the slot 10a can accommodate one type of atomizer 100, and the heating element 32 is heated in one heating mode; when the stopper 111 contacts the other side of the stopper notch 2212a, the slot 10a can accommodate another type of atomizer 100, and the heating element 32 is heated in another heating mode. This makes it more convenient during use, and the heat-not-burn atomizer device can be adapted to different atomizers by simply rotating the rotating element 22 until it contacts the stopper 111.

[0097] like Figure 5 As shown, the heat-not-burn atomizer device further includes a knob 23, which includes a connecting portion 231 and an operating portion 232. The connecting portion 231 is located in the main body 10 and is connected to the rotating member 22. The operating portion 232 is connected to the connecting portion 231, and the operating portion 232 at least partially extends outside the main body 10.

[0098] As an example, the connection portion 231 may be located at the end of the first tube 221, the main body 10 may have an arcuate groove 10b, the arcuate groove 10b connects the inside and the outside of the main body 10, and the operating portion 232 is located in the arcuate groove 10b. The user can rotate the rotating member 22 by turning the operating portion 232, so that the user can use the heat-not-burn atomization device conveniently.

[0099] Figure 6 Schematic diagram of the partial structure of a heat-without-burning atomization device provided in an embodiment of the present application. Figure 6 As shown, in this example, the sensing part of the distance sensor 311 faces the moving part 21. That is, the distance between the sensing part of the distance sensor 311 and the moving part 21 is directly detected by the distance sensor 311, so that the control board 312 directly controls the heating mode of the heating element 32 according to the distance between the sensing part of the distance sensor 311 and the moving part 21.

[0100] The embodiment of the present application also provides a control method for a heat-not-burn atomizer device, which can be used to control the aforementioned heat-not-burn atomizer device. In the control method, the heating power of the heating element 32 of the heat-not-burn atomizer device is controlled based on the depth of the atomizer 100 inserted into the heat-not-burn atomizer device.

[0101] By controlling the heating power of the heating element 32 of the heat-not-burn atomization device based on the depth at which the atomizer 100 is inserted into the heat-not-burn atomization device, the heating power of the heating element 32 can be changed according to the depth at which the atomizer 100 is inserted into the heat-not-burn atomization device, rather than heating at a fixed heating power, thereby reducing the deviation of the heating effect from the expected value, which is beneficial to improving the atomization effect.

[0102] Figure 7is a flow chart of a control method of a heat-not-burn atomization device provided in an embodiment of the present application. Figure 7 As shown, in the process of controlling the heating power of the heating element 32 of the heat-not-burn atomizing device based on the depth of the atomizer 100 inserted into the heat-not-burn atomizing device, the following steps may be adopted:

[0103] In step S11, location indication information is acquired.

[0104] The position indication information is used to indicate the depth at which the atomizer 100 is inserted into the heat-not-burn atomization device.

[0105] In step S12, the heating power of the heating element is determined based on the position indication information.

[0106] In this example, the position indication information may be obtained by the aforementioned distance sensor 311, and the position indication information may be information generated by the distance sensor 311 through distance detection. Figure 6 In the example shown, the distance sensor 311 directly detects the distance between the sensing part of the distance sensor 311 and the moving part 21, and Figure 2-Figure 5 The depth of the atomizer 100 inserted into the heat-not-burn atomizer device is related to the position of the portion of the lifting structure 20 located at the bottom of the groove in the slot 10a. The distance sensor 311 determines the height of the moving part 21 by detecting the distance between the moving part 21 and the rotating part 22 of the lifting structure 20. Therefore, the position indication information obtained by the distance sensor 311 can be used to characterize the depth of the atomizer 100 inserted into the heat-not-burn atomizer device.

[0107] The heating power of the heating element 32 is determined based on the position indication information that can characterize the depth of the atomizer 100 inserted into the heat-not-burn atomizer device, so that the heating power of the heating element 32 is related to the depth of the atomizer 100 inserted into the heat-not-burn atomizer device, thereby reducing the deviation of the heating effect from the expectation.

[0108] In some examples, when determining the heating power of the heating element based on the position indication information, one of multiple preset powers may be determined as the heating power according to the position indication information and a preset correspondence relationship. The preset correspondence relationship is a correspondence relationship between multiple preset heating powers and multiple position indication information.

[0109] That is to say, in the control device, a preset correspondence relationship between a plurality of heating powers and a plurality of position indication information can be pre-stored, that is, a preset correspondence relationship. For example, the maximum depth that the atomizer 100 can be inserted into the slot 10a is a, and the minimum depth is d. When the depth of the atomizer 100 inserted into the slot 10a is a, the corresponding preset heating power is a1, and when the depth of the atomizer 100 inserted into the slot 10a is d, the corresponding preset heating power is d1. When the depth of the atomizer 100 inserted into the slot 10a is b, b is between a and d, and the corresponding preset heating power is b1. When the depth of the atomizer 100 inserted into the slot 10a is c, c is between b and d, and the corresponding preset heating power is c1. In the process of using the heat-not-burn atomizer device, when the depth of the atomizer 100 inserted into the heat-not-burn atomizer device represented by the acquired position indication information is a, the heating power of the heating element 32 can be set to a1.

[0110] The heating power of the heating element 32 is determined by presetting the corresponding relationship, which is simple to implement and low in cost.

[0111] As an example, multiple position indication information may correspond to the same heating power.

[0112] For example, the position indication information indicating that the depth of the atomizer 100 inserted into the heat-not-burn atomization device is between depth a and depth b may correspond to the same heating power, which may be between a1 and b1.

[0113] As a more specific example, the difference between the maximum depth a and the minimum depth d is 4mm. From the depth a to the depth a-1mm, the heating power increases by 1 unit value for every decrease in the depth of the atomizer 100 inserted into the heating not burning atomization device by 1 unit depth. 1 unit depth may be 0.1mm, and 1 unit value may be 0.2W. The depth of the atomizer 100 inserted into the heating not burning atomization device is a-1mm, and the heating power is a1+2W; from the depth d to the depth d+1mm, the heating power decreases by 1 unit value for every increase in the depth of the atomizer 100 inserted into the heating not burning atomization device by 1 unit depth. The depth of the atomizer 100 inserted into the heating not burning atomization device is d+1mm, and the heating power is d1-2W; from the depth a-1mm to the depth d+1mm, the heating power is 0.

[0114] In other examples, in the process of determining the heating power of the heating element based on the position indication information, the heating power of the heating element can also be determined based on the difference between the depth of the atomizer 100 inserted into the heat-not-burn atomization device represented by the position indication information and a reference depth.

[0115] The reference depth may be preset. The reference depth may correspond to a preset reference power. When the depth of the atomizer 100 inserted into the heat-not-burn atomizer device is the reference depth, the heating element 32 performs heating at the preset reference power.

[0116] As an example, the reference depth may be the depth at which the atomizer 100 is inserted into the heat-not-burn atomization device when the heated portion of the atomizer 100 and the heating element 32 are in the most ideal relative position.

[0117] During use, the deviation of the heating effect from the expected one is caused by the fact that the depth of the atomizer 100 inserted into the heat-not-burn atomizer device is different from the ideal depth, and the heating power is fixed. In this example, the heating power of the heating element 32 is determined according to the difference between the depth of the atomizer 100 inserted into the heat-not-burn atomizer device and the reference depth, so as to reduce the deviation of the heating effect from the expected one.

[0118] As an example, the heating power of the heating element 32 may be determined in the following manner.

[0119] If the depth of the atomizer 100 inserted into the heat-not-burn atomizer device represented by the position indication information is equal to the reference depth, the preset reference power is used as the heating power of the heating element.

[0120] If the depth of the atomizer 100 inserted into the heat-not-burn atomizer device represented by the position indication information is greater than the reference depth, a power less than the preset reference power is used as the heating power of the heating element.

[0121] If the depth of the atomizer 100 inserted into the heat-not-burn atomizer device represented by the position indication information is less than the reference depth, a power greater than the preset reference power is used as the heating power of the heating element.

[0122] If the depth of the atomizer 100 inserted into the heat-not-burn atomizer device represented by the position indication information differs from the reference depth by more than a preset threshold, it is determined that the heating power of the heating element is 0.

[0123] When the depth of the atomizer 100 inserted into the heat-not-burn atomizer device is consistent with the reference depth, the heating element 32 directly heats with a preset reference power corresponding to the reference depth, so as to obtain a better atomization effect.

[0124] When the depth of the atomizer 100 inserted into the heat-not-burn atomizer device is greater than the reference depth, Figure 3As shown, the heated portion of the atomizer 100 is located at B, and the top of the aerosol matrix is ​​heated. At this time, the atomizer 100 is inserted too far into the slot 10a, and the portion of the atomizer 100 above the heated portion close to the mouthpiece is also heated, which may burn the mouthpiece. In this example, the heating is performed by using a power less than the preset reference power as the heating power of the heating element, thereby preventing the temperature of the portion of the atomizer 100 close to the mouthpiece from being too high, thereby reducing the risk of burning the mouthpiece.

[0125] When the depth of the atomizer 100 inserted into the heat-not-burn atomizer device is less than the reference depth, Figure 3 As shown, it is equivalent to that the heated portion of the atomizer 100 is located at A, the bottom of the aerosol matrix is ​​heated, while the top of the aerosol matrix is ​​not heated, which makes it difficult for the bottom of the aerosol matrix to be atomized to form an aerosol and diffuse out after heating. In this example, by heating with a power greater than the preset reference power as the heating power of the heating element, the bottom of the aerosol matrix can reach a higher temperature to promote the formation and diffusion of the aerosol.

[0126] When the depth of the atomizer 100 inserted into the heat-not-burn atomizer device differs too much from the reference depth, it is possible that only a small part of the heated portion of the atomizer 100 can be heated, or even the heated portion is completely misaligned with the heating element 32. Even if heating is performed with a very high heating power, it is difficult to form an aerosol. On the contrary, it may cause damage to the heat-not-burn atomizer device. Therefore, the heating power of the heating element can be determined to be 0, that is, heating is stopped to avoid damage to the heat-not-burn atomizer device.

[0127] The preset threshold here can be set according to the specific heating without burning atomization device, and the embodiment of the present application is not limited to this.

[0128] In some examples, the absolute value of the difference between the heating power of the heating element and the preset reference power, and the absolute value of the difference between the depth of the atomizer 100 inserted into the heat-not-burn atomization device represented by the position indication information and the reference depth are positively correlated.

[0129] When the depth of the atomizer 100 inserted into the heat-not-burn atomizer device is greater than the reference depth, the greater the absolute value of the difference between the depth of the atomizer 100 inserted into the heat-not-burn atomizer device and the reference depth, the higher the possibility of mouth scalding. At this time, by controlling the heating element 32 to heat with a smaller heating power, the increased risk of mouth scalding caused by the increase in the difference between the depth of the atomizer 100 inserted into the heat-not-burn atomizer device and the reference depth can be offset. Conversely, the lower the possibility of mouth scalding, the heating element 32 can be controlled to heat with a larger heating power to improve the atomization effect.

[0130] When the depth of the atomizer 100 inserted into the heat-not-burn atomizer device is less than the reference depth, the greater the absolute value of the difference between the depth of the atomizer 100 inserted into the heat-not-burn atomizer device and the reference depth, the less the aerogel matrix in the atomizer 100 is actually heated, and a large portion near the top of the aerosol matrix is ​​not heated, and the greater the absolute value, the larger the portion that is not heated, resulting in a worse atomization effect. At this time, the heating element 32 is controlled to heat with a greater heating power to ensure the atomization effect.

[0131] As an example, the absolute value of the difference between the heating power of the heating element and the preset reference power, and the absolute value of the difference between the depth of the atomizer 100 inserted into the heat-not-burn atomization device represented by the position indication information and the reference depth are proportional. In this way, the heating power of the heating element 32 can be simply and finely controlled, the atomization effect can be improved, and the risk of burning the mouth can be reduced.

[0132] For example, for every 0.1 mm change in the absolute value of the difference between the depth of the atomizer 100 inserted into the heat-not-burn atomizer device represented by the position indication information and the reference depth, the absolute value of the difference between the heating power of the heating element 32 and the preset reference power changes by 1 watt. This data is only used as an example, and for different heat-not-burn atomizer devices, the heating power may differ greatly, and can be set according to the specific heat-not-burn atomizer device.

[0133] In some examples, the heat-not-burn atomizer device may have multiple reference depths, each reference depth corresponding to a different preset reference power. In these examples, the heating power of the heating element may be determined based on the minimum difference between the depth of the atomizer 100 inserted into the heat-not-burn atomizer device represented by the position indication information and the different multiple reference depths. By setting multiple reference depths, the heat-not-burn atomizer device can be better matched with different atomizers 100.

[0134] For a heat-not-burn atomization device that can match different atomizers 100 , a reference depth can be preset corresponding to the type of atomizer 100 that can be matched.

[0135] For example, two reference depths may be preset for a heat-not-burn atomizer device that can match two atomizers 100. As an example, one of the two reference depths may be the depth of the atomizer 100 inserted into the heat-not-burn atomizer device when the heated portion of one atomizer 100 and the heating element 32 are in the most ideal relative position; the other of the two reference depths may be the depth of the atomizer 100 inserted into the heat-not-burn atomizer device when the heated portion of the other atomizer 100 and the heating element 32 are in the most ideal relative position.

[0136] As an example, the heating without burning atomization device can match two atomizers 100, namely a first atomizer and a second atomizer. The heating without burning atomization device is preset with two reference depths, namely a first reference depth and a second reference depth. The first reference depth is greater than the second reference depth. The preset reference power corresponding to the first reference depth is the first preset reference power, and the preset reference power corresponding to the second reference depth is the second preset reference power.

[0137] When the atomizer 100 is connected to the heat-not-burn atomizer device, the difference between the relative position relationship between the heated part of the atomizer 100 and the heating element 32 and the most ideal relative position relationship is mainly caused by operation, product dimensional accuracy and other reasons. This difference is usually much smaller than the structural and dimensional differences between two different atomizers 100. When the first atomizer is connected to the heat-not-burn atomizer device, the depth of the first atomizer inserted into the heat-not-burn atomizer device will be closer to the first reference depth, and when the second atomizer is connected to the heat-not-burn atomizer device, the depth of the second atomizer inserted into the heat-not-burn atomizer device will be closer to the second reference depth. By determining the heating power of the heating element 32 based on the minimum difference, the operation of the heating element 32 can be controlled more accurately to improve the atomization effect.
