[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0039] It is understood that the term "connection" in the following embodiments should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have electrical signal or data transmission with each other.

[0040] Existing aerosol generating devices typically use Hall effect sensors to detect the position of the movable cover. This approach requires placing the Hall sensors directly near the movable cover, resulting in limited functionality, high space occupancy, complex mechanical design, and poor reliability. Therefore, this application provides an aerosol generating device and its movable cover detection and control device. A detection plate generates capacitance changes based on its relative position to the movable cover. A main control device connected to the detection plate analyzes the detected capacitance to determine the movable cover's position and controls the aerosol generating device accordingly. This non-contact detection of the movable cover's position is achieved by monitoring capacitance changes, simplifying the structural design, reducing circuitry, minimizing material usage, and improving device functionality, safety, and user experience. The aerosol generating device also includes a housing with an atomizing medium receiving cavity. The movable cover covers this cavity and can move directionally back and forth across the housing surface, providing dust and water vapor protection. In one embodiment, the atomizing medium is a solid medium used to generate an aerosol when heated. The atomizing medium may include tobacco material, and aroma components may be further added to the tobacco material. The atomizing medium contains volatile tobacco aroma compounds released from the matrix when heated. In other embodiments, the atomizing medium may also be a liquid medium that atomizes to form an aerosol upon heating.

[0041] Please see Figure 1In one embodiment, an active cover detection control device of an aerosol generating device includes a detection electrode plate 110 and a master control device 120 connected to the detection electrode plate 110. The detection electrode plate 110 generates a change in capacitance according to a relative positional relationship with an active cover 210 of the aerosol generating device. The master control device 120 analyzes a position state of the active cover 210 according to the detected capacitance and controls the aerosol generating device according to the position state of the active cover 210.

[0042] The aerosol generating device can further include an apparatus housing 220 for mounting the active cover 210, the detection electrode plate 110, and the master control device 120. The apparatus housing 220 is provided with an atomization medium containing cavity 230, and the active cover 210 can be oriented to move back and forth on the surface of the apparatus housing 220 (which can be linear motion or rotation around a central axis) to close or open an atomization medium insertion port 232 of the atomization medium containing cavity 230. The active cover 210 can specifically include an active cover outer cover 212 located on one side of the apparatus housing 220 (in one embodiment, on the outer surface of the housing, and in other embodiments, it can also be partially or entirely housed in one end of the housing) and a structural part located inside the apparatus housing 220, which can be an integral structural assembly or a separate structural assembly.

[0043] The active cover 210 can be all or partially made of metal structure, and the metal structure part of the active cover 210 can be used as an active cover electrode plate 214. The detection electrode plate 110 can be fixed to the inner surface of the apparatus housing 220 or can be arranged at other positions in the apparatus housing 220, as long as it can generate a change in capacitance according to the relative positional relationship with the active cover electrode plate 214. In this embodiment, the detection electrode plate 110 is fixed to the inner surface of the apparatus housing 220 at a position corresponding to the active cover 210. The detection electrode plate 110 can be made of one or more groups of parallel electrode plates, or can form one or more groups of parallel electrode plates with the active cover electrode plate 214.

[0044] Specifically, the number of detection electrode plates 110 can be one or more, and a plurality of detection electrode plates 110 can form parallel capacitors, or the detection electrode plate 110 and the active cover electrode plate 214 can form parallel capacitors. Both the detection electrode plate 110 and the active cover electrode plate 214 are used as electrode plates, and the capacitance calculation formula is as follows:

[0045]

[0046] Wherein, C is the capacitance between the electrode plates, k is the relative permittivity of the material between the electrode plates, ε0 is the dielectric constant in vacuum, S is the relative area between the electrode plates, and d is the distance between the electrode plates. According to the structure of the detection electrode plate 110 and the different positional relationships between the movable cover electrode plate 214, the position state of the movable cover 210 can be analyzed according to the capacitance change, which can be divided into the following cases.

[0047] Case 1: The parallel capacitor formed between the movable cover electrode plate 214 and the detection electrode plate 110, the material and the distance of the electrode plates are fixed, the capacitance C is positively correlated with the relative area S between the electrode plates, and based on this, the relative position of the movable cover 210 and the detection electrode plate 110 can be reflected.

[0048] Case 2: The parallel capacitor formed between the detection electrode plates 110, the material and the relative area of the electrode plates are fixed, and when the movable cover electrode plate 214 enters between the detection electrode plates 110 as a third electrode, it is equivalent to changing the distance between the electrode plates, the capacitance C is negatively correlated with the distance d between the electrode plates, and based on this, the relative position of the movable cover 210 and the detection electrode plate 110 can be reflected.

[0049] Case 3: The parallel capacitor formed between the detection electrode plates 110 has an edge effect. When the movable cover electrode plate 214 approaches one side of the detection electrode plate 110 as a third electrode, it can change the edge effect of the electrode plate, the capacitance C is correlated with the edge effect of the electrode plate, and based on this, the relative position of the movable cover 210 and the detection electrode plate 110 can be reflected.

[0050] In addition, the movable cover detection control device can further include a detection electrode plate carrier 130, and the detection electrode plate 110 is arranged on the detection electrode plate carrier 130. For example, the detection electrode plate carrier 130 can be fixed inside the appliance housing 220, and the detection electrode plate 110 is arranged on the detection electrode plate carrier 130, which facilitates the installation and fixation of the detection electrode plate 110.

[0051] When the position of the movable cover 210 changes, the relative positional relationship between the movable cover electrode 214 and the detection electrode 110 changes, resulting in a change in capacitance that is detected by the main control device 120. The main control device 120 can then perform relevant operations or responses based on the capacitance change. For example, the main control device 120 can pre-store the capacitance of the movable cover 210 in different positions. After detecting the actual capacitance, it can determine the current position state of the movable cover 210, and thus control the aerosol generating device according to the current position state of the movable cover 210. For example, when the movable cover 210 is detected to be in a closed state (i.e., the atomizing medium insertion port 232 is closed), the aerosol generating device is controlled to enter a low-power sleep state; when the movable cover 210 is detected to be in an open state (i.e., the atomizing medium insertion port 232 is open), the aerosol generating device is controlled to enter a standby operation state or a heating operation state, etc. It can be understood that the operating parameters of the aerosol generating device in different states can be preset, which will not be elaborated here.

[0052] The aforementioned aerosol generating device's movable cover detection and control device uses a detection electrode 110 that generates capacitance changes based on its relative position to the movable cover 210 of the aerosol generating device. The main control device 120 analyzes the positional state of the movable cover 210 based on the detected capacitance and controls the aerosol generating device accordingly. This non-contact detection of the movable cover 210's positional state by monitoring capacitance changes provides high reliability, simplifies the detection structure, and reduces space occupancy.

[0053] The specific structure of the detection electrode 110 and its positional relationship with the movable cover electrode 214 are not unique. The detection electrode 110 can be distributed along the moving direction of the movable cover 210. When the movable cover electrode 214 serves as the third electrode, its relative position to the detection electrode 110 can be outside the detection electrode 110 or between the detection electrode 110s. The detection electrode 110 can be designed with a linear or segmented distribution. The edges of the detection electrode 110 can be straight lines, or regular serrations, waves, arcs, trapezoids, etc.

[0054] When the number of detection plates 110 is one, the detection plates 110 can be designed in a linear distribution manner. In one embodiment, such as... Figure 2 As shown, the detection electrode 110 and the movable cover electrode 214 form a parallel electrode plate, and the detection electrode 110 is a linear electrode plate. The detection electrode 110 can also be designed in a segmented distribution manner; in another embodiment, such as... Figure 3 As shown, the detection electrode 110 and the movable cover electrode 214 form a parallel electrode, and the detection electrode 110 is a segmented electrode.

[0055] When there are multiple detection plates 110, the detection plates 110 can be designed in a linear distribution manner. In one embodiment, such as... Figure 4 As shown, the number of detection plates 110 is two or more, forming parallel plates. The movable cover plate 214 is located between or outside the parallel plates, and each detection plate 110 in the parallel plates is a linear plate. The detection plates 110 can also be designed in a segmented distribution manner. In another embodiment, such as... Figure 5 As shown, there are two or more detection plates 110 forming parallel plates, and the movable cover plate 214 is located between or outside the parallel plates. Each detection plate 110 in the parallel plates is a segmented plate.

[0056] The specific structure of the main control device 120 is not unique; in one embodiment, such as... Figure 6 As shown, the main control device 120 includes a detection unit 122 and a main control unit 124. The detection unit 122 is connected to the detection electrode plate 110 and the main control unit 124. The detection unit 122 can be a discrete capacitance detection device (such as a touch chip or a capacitance sensor chip) electrically connected to the main control unit 124, or it can be a main control chip with a built-in capacitance detection module in the main control unit 124. The detection unit 122 converts capacitance changes into electrical quantities, such as voltage, current, resistance, frequency, and phase. The main control unit 124 then processes the electrical quantity data output by the detection unit 122 to determine the position state of the movable cover 210. Furthermore, the main control device 120 may also include a heating unit and / or a power supply module connected to the main control unit 124.

[0057] The capacitance detection principle of detection unit 122 is divided into mutual capacitance detection and self-capacitance detection. For example, Figure 6 As shown, for the self-capacitance detection method, one or a group of electrode plates are fixedly connected to the power supply ground, and another or a group of electrode plates are electrically connected to the detection unit 122. The detection electrode plate 110 and the movable cover electrode plate 214 can be equivalent to a self-capacitance Cs. This capacitance value is detected by the detection unit 122, and the main control unit 124 can perform corresponding operations or responses based on changes in the detected value. Figure 7 As shown, for the mutual capacitance detection method, all electrode plates are electrically connected to the detection unit 122 and are not connected to the power ground. The mutual capacitance Cm between the detection electrode plate 110 and the movable cover electrode plate 214 can be equivalent to the mutual capacitance Cm. The capacitance value is detected by the detection unit 122, and the main control unit 124 can perform corresponding operations or responses based on the changes in the detected value.

[0058] In one embodiment, the detection plate 110 is connected to the input port of the detection unit 122, and the movable cover plate 214 is connected to the output port of the detection unit 122. In other embodiments, the detection plate 110 can also be connected to the output port of the detection unit 122, and the movable cover plate 214 is connected to the input port of the detection unit 122. Further, in one embodiment, the detection plate 110 is a segmented plate, and is connected to the input port of the detection unit 122 and the power ground, respectively. In other embodiments, the detection plate 110 is a segmented plate, and is connected to the output port of the detection unit 122 and the input port of the detection unit 122, respectively.

[0059] Specifically, when the detection plate 110 and the movable cover plate 214 form parallel plates, for the self-capacitance detection mode, as shown in FIG. 2A, the detection plate 110 can be connected to the input port of the detection unit 122, and the movable cover plate 214 can be connected to the power ground. Alternatively, the movable cover plate 214 can be connected to the input port of the detection unit 122, and the detection plate 110 can be connected to the power ground. Further, as shown in FIG. 2B, when the detection plate 110 is a segmented plate, the segmented plate can be connected to the input port of the detection unit 122 and the power ground, respectively. Figure 8 Figure 9 Specifically, when the detection plate 110 and the movable cover plate 214 form parallel plates, for the self-capacitance detection mode, as shown in FIG. 2A, the detection plate 110 can be connected to the input port of the detection unit 122, and the movable cover plate 214 can be connected to the power ground. Alternatively, the movable cover plate 214 can be connected to the input port of the detection unit 122, and the detection plate 110 can be connected to the power ground. Further, as shown in FIG. 2B, when the detection plate 110 is a segmented plate, the segmented plate can be connected to the input port of the detection unit 122 and the power ground, respectively. Figure 10 Figure 11 Specifically, when the detection plate 110 and the movable cover plate 214 form parallel plates, for the self-capacitance detection mode, as shown in FIG. 2A, the detection plate 110 can be connected to the input port of the detection unit 122, and the movable cover plate 214 can be connected to the power ground. Alternatively, the movable cover plate 214 can be connected to the input port of the detection unit 122, and the detection plate 110 can be connected to the power ground. Further, as shown in FIG. 2B, when the detection plate 110 is a segmented plate, the segmented plate can be connected to the input port of the detection unit 122 and the power ground, respectively.

[0060] Further, when the number of detection plates 110 is more than two and the detection plates 110 form parallel plates, for the self-capacitance detection mode, some of the detection plates 110 can be connected to the input port of the detection unit 122, and some of the detection plates 110 can be connected to the power ground. For the mutual-capacitance detection mode, some of the detection plates 110 can be connected to the output port of the detection unit 122, and some of the detection plates 110 can be connected to the input port of the detection unit 122.

[0061] ​​The main control device 120 controls the aerosol generating device according to the position state of the movable cover 210 in a manner that is not unique. In one embodiment, the position state of the movable cover 210 includes a closed state and an open state. When the movable cover 210 is in the closed state, the main control device 120 controls the aerosol generating device to enter a low-power sleep state. When the movable cover 210 is in the open state, the main control device 120 controls the aerosol generating device to enter a standby operation state.

[0062] Specifically, such as Figures 12 to 14 As shown, position 1 can be defined as the position where the movable cover 210 is in the fully covered position (when the movable cover 210 completely blocks the atomizing medium insertion port 232), position 2 can be defined as the position between the fully covered and the fully open position (when the movable cover 210 partially blocks the atomizing medium insertion port 232, or when the movable cover 210 does not block the atomizing medium insertion port 232 at all, and the movable cover 210 can still move away from the atomizing medium insertion port 232), and position 3 can be defined as the position where the movable cover 210 is in the fully open position (when the movable cover 210 does not block the atomizing medium insertion port 232 at all, but the movable cover 210 cannot continue to move away from the atomizing medium insertion port 232). It is understood that a stop portion corresponding to the movable cover 210 being in position 1 and position 3 can be provided on the outer casing to limit the movable cover 210 to position 1 and position 3. The capacitance detection value of the movable cover 210 in position 1 is C1, the capacitance detection value of the movable cover 210 in position 2 is C2, and the capacitance detection value of the movable cover 210 in position 3 is C3. The main control unit 124 can then perform corresponding operations based on the actual detected capacitance changes. It can be understood that the capacitance range in position 1 is C1, the corresponding capacitance range in position 2 is C2, and the capacitance range in position 3 is C3.

[0063] When the movable cover 210 moves from position 1 to position 2 or position 3, the atomizing medium insertion port 232 opens, and the capacitance of the detection plate 110 changes from C1 to C2 or C3. The main control unit 124 detects this capacitance change and considers the movable cover 210 to be in the open state. If it was previously in a low-power sleep state, the main control unit 124 will automatically wake up, display interactive information, and then enter standby mode, monitoring in real time for start signals such as button presses or atomizing medium insertion detection.

[0064] When the active cover 210 moves from position 2 or position 3 to position 1, the atomization medium insertion port 232 is closed. The capacitance of the detection electrode plate 110 changes from C2 or C3 to C1. The master control unit 124 detects the capacitance change, and considers that the active cover 210 is in the closed state. If the active cover 210 is in the standby running state, the master control unit 124 displays interactive information and then enters the low-power sleep state. If the active cover 210 is in the heating running state, the master control unit 124 stops heating, displays interactive information, and then enters the low-power sleep state.

[0065] Further, in an embodiment, the open state includes a fully open state and an open state. The open state is that the active cover 210 moves from position 1 to position 2, partially or completely shielding the atomization medium insertion port 232. The fully open state is that the active cover 210 moves from position 1 or position 2 to position 3, completely shielding the atomization medium insertion port 232. When the master control device 120 detects that the active cover 210 is in the open state, the master control device 120 controls the aerosol generating device to enter the standby running state. When the master control device 120 detects that the active cover 210 is in the fully open state, the master control device 120 controls the aerosol generating device to enter the heating running state or the standby running state.

[0066] Specifically, when the active cover 210 moves from position 1 to position 2, the atomization medium insertion port 232 is open. The capacitance of the detection electrode plate 110 changes from C1 to C2. The master control unit 124 detects the capacitance change, and considers that the active cover 210 is in the open state. If the active cover 210 is in the low-power sleep state, the master control unit 124 automatically wakes up, displays interactive information, and then enters the standby running state to monitor the start signal such as the key or the atomization medium insertion detection in real time.

[0067] When the active cover 210 moves from position 1 to position 3, the atomization medium insertion port 232 is open. The capacitance of the detection electrode plate 110 changes from C1 to C3. The master control unit 124 detects the capacitance change, and considers that the active cover 210 is in the fully open state. If the active cover 210 is in the low-power sleep state, the master control unit 124 automatically wakes up, displays interactive information, and then enters the heating running state.

[0068] When the active cover 210 moves from position 2 to position 3, the atomization medium insertion port 232 is open. The capacitance of the detection electrode plate 110 changes from C2 to C3. The master control unit 124 detects the capacitance change, and considers that the active cover 210 is in the fully open state. If the active cover 210 is in the standby running state, the master control unit 124 starts heating, displays interactive information, and then enters the heating running state. If the active cover 210 is in the heating running state, the master control unit 124 stops heating, displays interactive information, and then enters the standby running state to monitor the start signal such as the key or the atomization medium insertion detection in real time.

[0069] Furthermore, in one embodiment, the closed state includes a fully closed state and a partially closed state. The partially closed state occurs when the movable cover 210 moves from position 3 to position 2, partially or completely obstructing the atomizing medium insertion port 232. The fully closed state occurs when the movable cover 210 moves from position 3 or position 2 to position 1, completely obstructing the atomizing medium insertion port 232. When the main control device 120 detects that the movable cover 210 is in the partially closed state, it controls the aerosol generating device to maintain its current operating state; when it detects that the movable cover 210 is in the fully closed state, it controls the aerosol generating device to enter a low-power sleep state.

[0070] Specifically, when the movable cover 210 moves from position 3 to position 2, the atomizing medium insertion port 232 opens. The capacitance of the detection plate 110 changes from C3 to C2. The main control unit 124 detects this capacitance change and considers the movable cover 210 to be in a closed state, maintaining the previous operating state.

[0071] When the movable cover 210 moves from position 2 to position 1, the atomizing medium insertion port 232 closes. The capacitance of the detection electrode 110 changes from C2 to C1. The main control unit 124 detects this capacitance change and considers the movable cover 210 to be in a fully closed state. If it was previously in standby mode, the main control unit 124 will display interactive information and then enter a low-power sleep state; if it was previously in heating mode, the main control unit 124 will stop heating, display interactive information, and then enter a low-power sleep state.

[0072] When the movable cover 210 moves from position 3 to position 1, the atomizing medium insertion port 232 closes. The capacitance of the detection plate 110 changes from C3 to C1. The main control unit 124 detects this capacitance change and considers the movable cover 210 to be in a fully closed state. If it was previously in heating operation, the main control unit 124 will stop heating, display interactive information, and then enter a low-power sleep state.

[0073] In one embodiment, an aerosol generating apparatus is also provided, including the aforementioned movable cover detection and control device. Furthermore, the aerosol generating apparatus may also include an apparatus housing with an atomizing medium receiving cavity. The apparatus housing is used to mount the movable cover, the detection electrode plate, and to house the main control device. The movable cover can reciprocate directionally on the surface of the apparatus housing to close or open the atomizing medium insertion port of the atomizing medium receiving cavity.
