Referring to fig. 1, in one embodiment, a removable cap detection device for an aerosol generating device includes a detection plate 110 and a main control device 120, wherein the main control device 120 is connected to the detection plate 110. The sensing plate 110 generates a capacitance change according to a relative positional relationship with the movable cap 210 of the aerosol-generating device; the main control device 120 analyzes the position state of the movable cover 210 based on the detected capacitance.
The aerosol-generating device may further comprise an appliance housing 220 for mounting the removable cap 210, the detection pad 110 and housing the master control device 120, among other things. The instrument housing 220 is provided with an atomized medium accommodating chamber 230, the movable cover 210 can be moved back and forth (linearly or rotatably around a central axis) on the surface of the instrument housing 220 to close or open the atomized medium insertion opening 232 of the atomized medium accommodating chamber 230, and the movable cover 210 can specifically include a movable cover outer cover 212 and a structural part located inside the instrument housing 220, which are located at one side of the instrument housing 220 (in one embodiment, at the outer surface of the housing, and in other embodiments, may be partially or completely accommodated at one end of the housing), and both of which may be an integrated structural component or a separate structural component.
The movable cover 210 may be entirely or partially made of a metal structure, the metal structure of the movable cover 210 may be used as the movable cover plate 214, and the detection plate 110 may be fixed to the inner surface of the tool case 220, or may be disposed at another position in the tool case 220, and may be changed in capacitance according to the relative position relationship with the movable cover plate 214. In this embodiment, the detection plate 110 is fixed to the inner surface of the device case 220 at a position corresponding to the movable cover 210. The sensing plate 110 may be one or more parallel plates, or may be one or more parallel plates with the movable cover plate 214.
Specifically, the number of the detection plates 110 may be one or more, a parallel capacitor may be formed between a plurality of detection plates 110, or a parallel capacitor may be formed between the detection plates 110 and the movable cover plate 214, and both the detection plates 110 and the movable cover plate 214 are used as electrode plates, and the capacitance calculation formula is as follows:
wherein C is the capacitance between the electrode plates, k is the relative permittivity of the material between the electrode plates, ε 0 S is the relative area between the electrode plates, and d is the distance between the electrode plates. The analysis of the position state of the movable cover 210 according to the capacitance variation can be classified into the following cases according to the structure of the sensing plate 110 and the position relationship with the movable cover plate 214.
Case 1: the parallel capacitor formed between the active cap plate 214 and the sensing plate 110 has a constant material and spacing, and the capacitance C has a positive correlation with the relative area S between the plates, which can reflect the relative position of the active cap 210 and the sensing plate 110.

Case 3: the parallel capacitor formed between the sensing plates 110 has an edge effect. When the movable cover plate 214 is used as a third electrode and is close to one side of the detection plate 110, the edge effect of the plate can be changed, and the capacitance C has a certain correlation with the edge effect of the plate, so that the relative position of the movable cover 210 and the detection plate 110 can be reflected.

For example, the main control device 120 may pre-store the capacitance values of the movable lid 210 at different positions, and determine the current position state of the movable lid 210 after detecting the actual capacitance value, so as to control the aerosol generating device according to the current position state of the movable lid 210, for example, when detecting that the movable lid 210 is in the closed state (i.e., the aerosol insertion port 232 is closed), the aerosol generating device is controlled to be in the low power consumption sleep state, and when detecting that the movable lid 210 is in the open state (i.e., the aerosol insertion port 232 is open), the aerosol generating device is controlled to enter the standby operation state or the heating operation state. It will be appreciated that the operating parameters of the aerosol-generating device in the different states may be pre-set and will not be described in further detail herein.
In the above-mentioned movable cap detection device of the aerosol generating device, the detection electrode plate 110 generates capacitance change according to the relative position relationship with the movable cap 210 of the aerosol generating device, and the main control device 120 analyzes the position state of the movable cap 210 according to the detected capacitance.

The specific configuration of the sensing plate 110, and the positional relationship to the moveable cover plate 214, is not unique. The detecting plates 110 may be distributed along the moving direction of the movable cover 210, and when the movable cover plate 214 is used as the third plate, the position relative to the detecting plates 110 may be outside the detecting plates 110 or between the detecting plates 110. The detection plate 110 may be designed in a linear distribution manner or a sectional distribution manner, and the edge of the detection plate 110 may be a straight line, or may be a regular sawtooth, wave, arc, trapezoid, or the like.

The detection unit 122 may be a discrete capacitive detection device (such as a touch chip or a capacitive sensor chip) electrically connected to the main control unit 124, or may be a main control chip of a capacitive detection module built in the main control unit 124.

The manner in which the main control device 120 controls the aerosol-generating device according to the position state of the movable cover 210 is not exclusive, and in one embodiment, the position state of the movable cover 210 includes a closed state and an open state, the main control device 120 controls the aerosol-generating device to enter a low power consumption sleep state when the movable cover 210 is in the closed state, and the main control device 120 controls the aerosol-generating device to enter a standby operation state when the movable cover 210 is in the open state.
Specifically, as shown in fig. 12 to 14, a position when the movable cover 210 is in the covering position (when the movable cover 210 completely blocks the atomized medium insertion port 232) may be defined as a position 1, a position between the covering position and the opening position of the movable cover 210 may be defined as a position 2 (when the movable cover 210 partially blocks the atomized medium insertion port 232, or when the movable cover 210 does not block the atomized medium insertion port 232 at all, and the movable cover 210 can still move to a position away from the atomized medium insertion port 232), and a position when the movable cover 210 is in the opening position may be defined as a position 3 (when the movable cover 210 does not block the atomized medium insertion port 232 at all, but the movable cover 210 cannot move to a direction away from the atomized medium insertion port 232 at all). It is understood that the stop portions corresponding to the positions 1 and 3 of the movable cover 210 may be provided on the housing to limit the movable cover 210 to the positions 1 and 3. The capacitance detection value when the movable cover 210 is at the position 1 is C1, the capacitance detection value when the movable cover 210 is at the position 2 is C2, the capacitance detection value when the movable cover 210 is at the position 3 is C3, and the main control unit 124 can perform corresponding operations according to the actually detected capacitance change. It is understood that the capacitance range at position 1 may be C1, the corresponding capacitance range at position 2 may be C2, and the corresponding capacitance range at position 3 may be C3.
When the movable cover 210 moves from position 1 to position 2 or position 3, the atomized medium insertion port 232 is opened, and the capacitance of the detection electrode plate 110 changes from C1 to C2 or C3. When the main control unit 124 monitors the capacitance change, it determines that the movable cover 210 is in the open state, and if the movable cover is in the low power consumption sleep state before that, the main control unit 124 automatically wakes up, displays the interactive information, then enters the standby operation state, and monitors the start signal such as the key or the insertion detection of the atomized medium in real time.
When the movable cover 210 moves from position 2 or position 3 to position 1, the atomizing medium insertion port 232 is closed. The capacitance of the sensing plate 110 changes from C2 or C3 to C1. When the main control unit 124 monitors the capacitance change condition, it determines that the movable cover 210 is in the closed state, and if the movable cover is in the standby operation state before that, the main control unit 124 displays the interactive information and then enters the low-power consumption sleep state; if the heating operation state is performed before, the main control unit 124 stops heating, displays the interactive information, and then enters the low power consumption sleep state.
Further, in one embodiment, the open state includes a fully open state and an open-in-the-middle state, i.e., the movable cover 210 moves from position 1 to position 2, partially blocking or not blocking the atomizing medium insertion port 232 at all; the fully open state, i.e., the movable cover 210 is moved from position 1 or position 2 to position 3, does not block the atomizing medium insertion port 232 at all. When detecting that 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; upon detecting that the moveable cover 210 is in the fully open state, the aerosol-generating device is controlled to enter a heating or standby operating state.
Specifically, when the movable cover 210 moves from position 1 to position 2, the atomizing medium insertion port 232 is opened. The capacitance of the sensing plate 110 changes from C1 to C2. When the main control unit 124 monitors the capacitance change, it may be considered that the movable cover 210 is in the open state, and if the movable cover is in the low power consumption sleep state before that, the main control unit 124 automatically wakes up, displays the interactive information, and then enters the standby operation state to monitor the start signal such as the key or the insertion detection of the atomized medium in real time.
When the movable cover 210 moves from position 1 to position 3, the atomizing medium insertion port 232 is opened. The capacitance of the sensing plate 110 changes from C1 to C3. When the main control unit 124 monitors the capacitance change condition, it may be considered that the movable cover 210 is in a fully open state, and if the movable cover is in a low power consumption sleep state before that, the main control unit 124 automatically wakes up to display the interactive information, and then enters a heating operation state.
When the movable cover 210 moves from position 2 to position 3, the atomizing medium insertion port 232 is opened. The capacitance of the sensing plate 110 changes from C2 to C3. When the main control unit 124 monitors the capacitance change condition, it may be considered that the movable cover 210 is in a fully opened state, and if the movable cover is in a standby operation state before that, the main control unit 124 starts heating, displays interaction information, and then enters a heating operation state; if the heating operation state is in the previous state, the main control unit 124 stops heating, displays the interactive information, then enters a standby operation state, and monitors the key or the atomized medium insertion detection and other starting signals in real time.
Further, in one embodiment, the closed state includes a fully closed state and a closing in-process state, i.e., the movable cover 210 is moved from position 3 to position 2, partially blocking or completely unblocking the atomizing medium insertion port 232. The completely closed state, that is, the movable cover 210 moves from the position 3 or the position 2 to the position 1, and completely blocks the atomizing medium insertion port 232. The master control device 120 controls the aerosol-generating device to maintain a current operating state when detecting that the movable lid 210 is in the closed state; upon detecting that the movable lid 210 is in the fully closed state, the aerosol-generating device is controlled to enter a low-power sleep state.
Specifically, when the movable cover 210 is moved from the position 3 to the position 2, the atomizing medium insertion port 232 is opened. The capacitance of the sensing plate 110 changes from C3 to C2. When the main control unit 124 detects the capacitance change, it may determine that the movable cover 210 is in the closed state, and maintain the previous operation state.
When the movable cover 210 is moved from position 2 to position 1, the atomizing medium insertion port 232 is closed. The capacitance of the sensing plate 110 changes from C2 to C1. When the main control unit 124 monitors the capacitance change condition, it may be considered that the movable cover 210 is in a completely closed state, and if the movable cover is in a standby operation state before that, the main control unit 124 displays interaction information and then enters a low power consumption sleep state; if the heating operation state is performed before, the main control unit 124 stops heating, displays the interactive information, and then enters the low power consumption sleep state.
When the movable cover 210 moves from position 3 to position 1, the atomizing medium insertion port 232 is closed. The capacitance of the sensing plate 110 changes from C3 to C1. When the main control unit 124 monitors the capacitance change, it may be considered that the movable cover 210 is in a completely closed state, and if the movable cover is in a heating operation state before that, the main control unit 124 stops heating, displays interaction information, and then enters a low power consumption sleep state.
