[0027] See also Figure 1 and Figure 2 The present application provides an aerosol generating device 100. The aerosol generating device 100 is used to generate aerosol from an aerosol generating substrate. The aerosol generating device 100 includes a knock detection unit 10, a motion detection unit 20, a controller 30 and an operation system 40.

[0028] The knock detection unit 10 is configured to detect a knocking action of the aerosol generating device 100, and generate a knock signal based on the knocking action. In response to the knock signal generated by the knock detection unit 10, the motion detection unit 20 is configured to detect the motion state of the aerosol generating device 100, and the motion state includes a first state and a second state. In response to the motion detection unit 20 detecting the first state, the controller 30 is configured to give up responding to the knock signal. In response to the motion detection unit 20 detecting the second state, the controller 30 is configured to control the operation system 40 to operate according to the knock signal.

[0029] The aerosol generating device 100 provided in the embodiment of the present application is used to heat the aerosol generating matrix to generate an aerosol for the user to use. Among them, the heating method can be convection, conduction, radiation or a combination thereof. The form of the aerosol generating matrix can be a liquid, a gel, a paste or a solid, etc. When the aerosol generating matrix is ​​a solid, it can be a solid in the form of crushed, granulated, powdered, granular, strip or sheet. The aerosol generating matrix includes but is not limited to materials used for medical, health, health, and beauty purposes. For example, the aerosol generating matrix is ​​a medicinal liquid, an oil, or the aerosol generating matrix is ​​a plant material, such as the roots, stems, leaves, flowers, buds, seeds, etc. of plants. That is, the embodiments of the present application do not limit the heating method, form, and use of the aerosol generating matrix.

[0030] The aerosol generating device 100 performs the function of the aerosol generating device 100 through the operation of the operation system 40. For example, the operation system 40 operates to perform a heating function of the aerosol generating device 100, and the aerosol generating device 100 generates aerosol for use by a user during the execution of the heating function.

[0031] The controller 30 can control the operating state of the operating system 40. The operating state of the operating system 40 includes the startup of the operating system 40, the shutdown of the operating system 40, the operating power of the operating system 40, etc., which are not limited here. The controller 30 can perform control on the operating system 40 in response to the knocking signal, and trigger corresponding control of the operating system 40 according to the knocking signal. For example, the frequency of the knocking signal represents the number of knocking actions, and the controller 30 triggers different controls on the operating system 40 according to different numbers of knocking actions represented by the knocking signal. Among them, the different controls on the operating system 40 may include the control of different operating components / elements of the operating system 40, and the control of different operating states of the same operating component / element of the operating system 40.

[0032] In one application scenario, the aerosol generating device 100 is in a relatively static state, and an external force acts on the aerosol generating device 100 so that the tapping detection unit 10 detects a tapping action. This application scenario is often an application scenario in which a user wants to actively interact with the aerosol generating device 100 by tapping. For example, when a user holds the aerosol generating device 100, the aerosol generating device 100 is in a static state relative to the user, and the user taps the aerosol generating device 100 with a finger or other object, so that the tapping detection unit 10 detects a tapping action.

[0033] In another application scenario, the aerosol generating device 100 is in a state of relative motion, and the collision between the motion of the aerosol generating device 100 itself and other objects may cause the knocking detection unit 10 to detect a knocking action. This knocking action is often not a knocking action that occurs when the user actively wants to interact with the aerosol generating device 100, but a knocking action that is triggered by mistake. If the controller 30 responds to the knocking signal generated by the knocking action that is triggered by mistake, and the controller 30 controls the operating system 40 accordingly to make the operating system 40 run, it may cause the operating system 40 to run ineffectively and waste power consumption, and may also cause safety problems. For example, if the knocking action that is triggered by mistake causes the aerosol generating device 100 to perform a lighting function, power consumption will be wasted in vain. For another example, in a scenario where the aerosol generating device 100 is placed in a backpack, the knocking action that is triggered by mistake causes the aerosol generating device 100 to perform a heating function, causing flammable items in the backpack to be ignited, which causes safety problems.

[0034] In some application scenarios, there is a possibility that the user can use the characteristics of the aerosol generating device 100 that the collision with other objects can be identified as a knocking action, and actively wave the aerosol generating device 100 to knock other objects to trigger the operation of the operating system 40. However, this method can easily cause damage to the aerosol generating device 100.

[0035] Based on the above application scenarios, if the aerosol generating device 100 is in a state of relative motion, even if a knocking action occurs, it will not trigger the operation of the operating system 40. This can avoid triggering the operation of the operating system 40 in a scenario where the user does not actively interact with the aerosol generating device 100 by knocking, thereby avoiding wasting power consumption or causing safety problems. It can also avoid the user triggering the operation of the operating system 40 by waving the aerosol generating device 100 to knock other objects, thereby affecting the service life of the aerosol generating device 100.

[0036] In the aerosol generating device 100 of the present application, the motion detection unit 20 can detect the motion state of the aerosol generating device 100, and the motion state includes a first state and a second state. Among them, the first state is the state of relative motion of the aerosol generating device 100, and the second state is the state of relative stillness of the aerosol generating device 100. In response to the motion state detected by the motion detection unit 20, the controller 30 correspondingly determines whether to respond to the knocking signal generated by the knocking detection unit 10 based on the knocking action. Among them, in response to the first state detected by the motion detection unit 20, the controller 30 abandons responding to the knocking signal. In this way, when the aerosol generating device 100 is in relative motion, the controller 30 will not control the operation system 40 to perform the corresponding interactive function according to the knocking signal, that is, it can prevent the aerosol generating device 100 from mistakenly performing the corresponding interactive function when it is mistakenly triggered by the knocking action. In response to the second state detected by the motion detection unit 20, the controller 30 responds to the tapping signal and controls the operation of the operating system 40 according to the control signal, so as to control the operating system 40 to perform the corresponding interactive function, that is, when the aerosol generating device 100 is subjected to normal tapping interaction, the aerosol generating device 100 performs the corresponding interactive function.

[0037] See also Figures 1 to 3 In some embodiments, the controller 30 is configured to control the operation system 40 to operate according to the frequency of the knocking signal. The frequency of the knocking signal refers to the number of knocking signals generated within a preset period. For example, the preset period starts from the first knocking signal (such as Figure 3 The generation of the signal S1) (such as Figure 3 t1) and continues for a preset time (such as Figure 3 The number of knocking signals generated in a preset period is the frequency of the knocking signal. The next knocking signal (such as Figure 2 The signal S3 at time t3 is used as the first signal of the next preset cycle.

[0038] See also Figure 2 In some embodiments, the operating system 40 includes an indication component 41. The operation of the operating system 40 includes the indication component 41 outputting a detectable indication. In response to the tapping signal of the first frequency, the controller 30 is configured to control the indication component 41 to output a detectable indication.

[0039] Please combine Figure 3 The knocking signal of the first frequency refers to the first number of knocking signals generated within a preset period. When the number of knocking signals generated within a preset period is the first number, the frequency of the knocking signal is the first frequency. For example, the first frequency is 2 times per period, which means that within a preset period (such as Figure 3Two knock signals are generated within T1 (such as Figure 3 In the case of signal S1 and signal S2), the tapping signal is of the first frequency.

[0040] A detectable indication is an indication information that can be detected by a user. In some embodiments, the indication component 41 includes a light-emitting indicator, which refers to a device of the aerosol generating device 100 that can emit an indication in the form of light visible to the user, and the light emitted by the light-emitting indicator is visible to the user of the aerosol generating device 100. The light-emitting indicator can be enclosed in a housing of the aerosol generating device so that the light emitted from the light-emitting indicator is visible through a window of the aerosol generating device 100. Correspondingly, the detectable indication includes a visual indication.

[0041] In some embodiments, the indication component 41 includes an audio indicator, which refers to a device of the aerosol generating device 100 that can give an indication to the user in a tactile form. The audio indicator may include a speaker. Correspondingly, the detectable indication includes an audible indication.

[0042] In some embodiments, the indication component 41 includes a tactile feedback unit, which refers to an element of the aerosol generating device 100 that can provide an indication to the user in a tactile form. The tactile feedback unit may include a vibration motor or a tactile motor, such as an eccentric rotating mass actuator. Correspondingly, the detectable indication includes a tactile indication.

[0043] The indication component 41 includes at least one of the above-mentioned light indicator, audio indicator, and tactile feedback unit. For example, the indication component 41 includes any one of the above-mentioned light indicator, audio indicator, and tactile feedback unit, a combination of any two, or a combination of the three.

[0044] The indication information includes parameter information of the aerosol generating device 100. In some embodiments, the aerosol generating device 100 includes a power source, and the detectable indication is used to indicate the remaining power information of the power source. In some embodiments, the aerosol generating device 100 includes a clock unit, and the detectable indication is used to indicate the date / time. In some embodiments, the detectable indication is used to indicate the heating temperature of the aerosol generating device 100, for example, the aerosol generating device 100 includes a heating chamber, and the aerosol generating substrate is heated in the heating chamber to generate an aerosol, and the detectable indication is used to indicate the temperature of the heating chamber.

[0045] See also Figure 2 In some embodiments, the operating system 40 includes a heating component 42. The operation of the operating system 40 includes the heating component 42 starting to heat. The heating component 42 starting to heat can heat the aerosol generating substrate to generate an aerosol. In response to the knocking signal of the second frequency, the controller 30 is configured to control the heating component 42 to start.

[0046] The knocking signal of the second frequency refers to a knocking signal of a second number generated within a preset period. When the number of knocking signals generated within a preset period is the second number, the frequency of the knocking signal is the second frequency.

[0047] In some embodiments, the second frequency is greater than the first frequency. That is, the second number is greater than the first number. For example, the first number is 2 knock signals, and the second number is 3 knock signals. In response to the motion detection unit 20 detecting the second state, the controller 30 controls the indication component 41 to output a detectable indication according to the 2 knocking actions of the aerosol generating device 100 within a preset period, or controls the heating component 42 to start heating according to the 3 knocking actions of the aerosol generating device 100 within a preset period. Since the indication component 41 outputs a detectable indication and does not cause safety problems, while the heating component 42 mistakenly starts heating and easily causes safety problems, the controller 30 is configured to control the heating component 42 to start heating with a higher difficulty than the difficulty of controlling the indication component 41 to output a detectable indication, which can further avoid the mistaken start of the heating component 42.

[0048] In some embodiments, based on the fact that the output of the detectable indication by the indication component 41 does not cause safety problems, the controller 30 can also be configured to directly control the indication component 41 to output a detectable indication in response to a knocking signal of the first frequency without performing motion state detection; in response to a knocking signal of the second frequency, the motion state detected by the motion detection unit 20 is obtained, and if the motion state is the first state, the knocking signal of the second frequency is abandoned, and if the motion state is the second state, the heating component 42 is controlled to start heating. Among them, the second frequency is greater than the first frequency. In other words, when the knocking signal is the first frequency, it is not necessary to make a judgment in combination with the motion state detected by the motion detection unit 20, and the indication component 41 is allowed to be directly controlled to output a detectable indication. Since the heating component 42 is easily caused to cause safety problems by mistakenly starting the heating, a stricter starting condition is set, and the heating component 42 is controlled to start heating only when the knocking signal is the second frequency and the motion state of the aerosol generating device 100 is the second state. Otherwise, if the knocking signal is the second frequency, but the motion state of the aerosol generating device 100 is the first state, the knocking signal of the second frequency is abandoned to avoid the heating component 42 from being mistakenly started.

[0049] See also Figure 1 and Figure 2 In some embodiments, the knock detection unit 10 includes one or more of a vibration sensor, an accelerometer, a gyroscope, and a sound sensor. The knock detection unit 10 detects one or more of a vibration parameter of the aerosol generating device 100, a posture parameter of the aerosol generating device 100, and an environmental sound parameter to identify the knocking action of the aerosol generating device 100.

[0050] For example, the knock detection unit 10 includes a vibration sensor, which can detect the vibration frequency and vibration intensity of the aerosol generating device 100, and determine whether the aerosol generating device 100 is knocked by comparing the vibration frequency and vibration intensity of the aerosol generating device 100 with preset frequency thresholds and intensity thresholds.

[0051] For example, the knock detection unit 10 includes a gyroscope, which can detect the posture parameters of the aerosol generating device 100 to determine the shaking degree of the aerosol generating device 100 according to the posture parameters of the aerosol generating device 100, and to determine whether the aerosol generating device 100 is knocked based on the shaking degree of the aerosol generating device 100.

[0052] For example, the knock detection unit 10 includes a sound sensor, and the sound sensor determines whether a knock sound is emitted by identifying environmental sound parameters, so as to determine whether the aerosol generating device 100 is knocked based on the knock sound.

[0053] See also Figure 1 and Figure 2 In some embodiments, the motion detection unit 20 includes an accelerometer and / or a gyroscope. The accelerometer and the gyroscope are used to collect acceleration data of the aerosol generating device 100 at a preset collection frequency. The motion detection unit 20 is configured to output the motion state of the aerosol generating device 100 according to the acceleration data of the aerosol generating device 100. That is, the motion detection unit 20 uses the acceleration data of the aerosol generating device 100 to determine whether the aerosol generating device 100 is in a relatively static or relatively moving state.

[0054] In some embodiments, the acceleration data includes a plurality of acceleration data of three different reference axes. The motion detection unit 20 is configured to obtain the absolute value difference between the maximum value and the minimum value of the plurality of acceleration data of each reference axis; when the absolute value difference of each reference axis is less than the acceleration threshold, output the second state of the aerosol generating device 100; and when the absolute value difference of any axis is greater than or equal to the acceleration threshold, output the first state of the aerosol generating device 100.

[0055] For example, the three different reference axes are the X-axis, the Y-axis, and the Z-axis respectively. The motion detection unit 20 collects the acceleration data of the aerosol generating device 100 at a preset acquisition frequency. It can collect multiple acceleration data of each axis among the three different reference axes of the X-axis, the Y-axis, and the Z-axis within a preset acquisition period, and respectively obtain the absolute value differences corresponding to the X-axis, the Y-axis, and the Z-axis. Taking the X-axis as an example, the X-axis includes acceleration data x1, x2, x3, x4, x5, where x2 is the maximum acceleration of the X-axis and x4 is the minimum acceleration of the X-axis. Let the absolute value difference of the X-axis be X0, then the absolute value difference X0 of the X-axis = 丨x2 - x4丨.

[0056] The acceleration thresholds can be three different thresholds respectively configured for the three different reference axes, or the three different reference axes adopt the same acceleration threshold standard, or two of the three different reference axes adopt the same acceleration threshold standard, and the other reference axis adopts a different acceleration threshold standard, which is not limited here.

[0057] When the absolute value differences of each reference axis are all less than the acceleration threshold, it can be considered that the aerosol generating device 100 is stationary or has a small motion trend and is in a relatively stationary state. In this case, the motion detection unit 20 outputs the second state of the aerosol generating device 100. The controller 30 can determine that the tapping action of the aerosol generating device 100 is a normal trigger in response to the second state, so as to control the operation system 40 to run the corresponding interaction function according to the tapping signal.

[0058] When the absolute value difference of any one axis is greater than or equal to the acceleration threshold, for example, when the absolute value difference of any one axis, any two axes, or all three axes among the X-axis, the Y-axis, and the Z-axis is greater than or equal to the acceleration threshold, it is considered that the aerosol generating device 100 has a large motion trend and is in a relatively moving state. In this case, the motion detection unit 20 outputs the first state of the aerosol generating device 100. The controller 30 can determine that the tapping action of the aerosol generating device 100 is a false trigger in response to the first state, and then abandon responding to the tapping signal generated by the tapping action.

[0059] Please refer to Figure 1 and Figure 4 , this application also provides a control method, which can be applied to the aerosol generating device 100 to prevent the function of the operation system 40 of the aerosol generating device 100 from being falsely triggered. The control method includes the following steps:

[0060] 01: Detect the tapping action of the aerosol generating device 100 and generate a tapping signal based on the tapping action;

[0061] 02: In response to the knocking signal, detecting a motion state of the aerosol generating device 100 , the motion state including a first state and a second state;

[0062] 03: If the motion state is the first state, give up responding to the tapping signal; and

[0063] 04: If the motion state is the second state, the operation system 40 is controlled to operate according to the knocking signal.

[0064] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. At the same time, other implementation methods can be derived from the above embodiments, so that structural and logical replacements and changes can be made without departing from the scope of this disclosure.

[0065] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
