[0014] Secondly, this application provides an aerosol generation device, including an aerosol heating assembly and an aerosol heating control device according to any optional embodiment of the first aspect. The aerosol heating assembly includes an aerosol matrix, a resistance heating element, and a plurality of electrical contacts. The resistance heating element is electrically connected to the plurality of electrical contacts and is configured to heat the aerosol in the aerosol matrix.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0033] In existing aerosol generation equipment, the aerosol heating control device and the aerosol heating component need to be oriented. Generally, a socket is opened on one of the aerosol heating component or the aerosol heating control device, and the other is equipped with a protruding electrical connector. The aerosol heating component and the aerosol heating control device are connected by plugging in the socket and the electrical connector one by one. However, this oriented connection method requires users to align the sockets when using the aerosol generation equipment, which results in complicated installation and low convenience.

[0034] To address the aforementioned issues, this application designs an aerosol heating control device and an aerosol generating device. The design incorporates a connecting assembly with multiple connecting electrodes. A heating power supply unit is connected in series with each connecting electrode of the connecting assembly via a switching unit. The control unit can control the switching unit so that when at least two target electrodes of the connecting assembly are electrically connected to the electrical contacts of the aerosol heating assembly, the switching unit is turned on, forming a conductive circuit encompassing the heating power supply unit, the at least two target electrodes, and the aerosol heating assembly. This allows the aerosol heating assembly to be connected to the aerosol heating control device at any point along the connecting assembly, meaning the aerosol heating assembly and the aerosol heating control device can be electrically connected at any angle. This reduces the installation difficulty and improves the ease of installation for the aerosol generating device.

[0035] Based on the above ideas, this application first provides an aerosol heating control device, such as... Figure 1 As shown, the aerosol heating control device includes a control unit 10, a heating power supply unit 20, a switching unit 30, and a connecting component 40. The connecting component 40 includes multiple connecting electrodes 410. The heating power supply unit 20 is connected in series with each connecting electrode 410 of the connecting component 40 through the switching unit 30. The control unit 10 is electrically connected to the control terminal of the switching unit 30. Here, "aerosol heating control device" refers to a device capable of heating an aerosol heating component. For example, in the case of an electronic cigarette, the aerosol heating control device can specifically be an electronic cigarette holder, and the aerosol heating component can specifically be a cartridge, i.e., a component containing e-liquid and capable of heating the e-liquid; the aerosol heating component can also be a heated non-combustible component, i.e., a component used to heat a solid cigarette.

[0036] In the aerosol heating control device designed above, the aerosol heating component N can be connected to the connecting component 40 of the aerosol heating control device. Specifically, the aerosol heating component N can have an electrical contact N1, and the electrical contact N1 of the aerosol heating component N can be electrically connected to at least two target electrodes of the connecting component 40. In this case, the control unit 10 can control the switching unit 30 to conduct and form a conducting circuit of the heating power supply unit 20, at least two target electrodes and the aerosol heating component N, so that the heating power supply unit 20 supplies power to the aerosol heating component N through at least two target electrodes, thereby enabling the aerosol heating component N to heat the aerosol matrix inside to generate aerosol.

[0037] The aerosol heating control device designed above includes a connection component comprising multiple connection electrodes. The heating power supply unit is connected in series with each connection electrode of the connection component via a switching unit. The control unit can control the switching unit so that when at least two target electrodes of the connection component are electrically connected to the electrical contacts of the aerosol heating component, the control unit is turned on to form a conductive circuit of the heating power supply unit, at least two target electrodes, and the aerosol heating component. This allows the aerosol heating component to achieve effective electrical connection with any electrode of the connection component, meaning that the aerosol heating component and the aerosol heating control device can be electrically connected at any angle, thereby reducing the installation difficulty of the aerosol generation equipment and improving installation convenience.

[0038] In an optional implementation of this embodiment, as one possible implementation, such as Figure 2As shown, the switching unit 30 designed in this scheme may include multiple controllable switches k1, wherein the number of multiple controllable switches k1 is the same as the number of multiple connecting electrodes 410; the heating power supply unit 20 is electrically connected to the first terminal of each controllable switch k1, the second terminal of each controllable switch k1 is electrically connected to a connecting electrode 410, and the control unit 10 is electrically connected to the control terminal of each controllable switch k1. Specifically, the controllable switches k1 may be relays, field-effect transistors, IGBTs, etc.

[0039] The switch unit 30 designed above, the control unit 10 can control each controllable switch k1. When at least two target electrodes of the connecting component 40 are electrically connected to the electrical contact N1 of the aerosol heating component N, the control unit 10 can control the controllable switches k1 connected to the at least two target electrodes to close respectively. This makes the heating power supply unit 20 form a conductive circuit with the aerosol heating component N through the closed controllable switch k1, the two target electrodes and the electrical contact N1, so that the aerosol heating component N can heat the aerosol matrix inside to generate aerosol.

[0040] In the above-described embodiments, the control unit can effectively connect the aerosol heating component to any electrode of the connecting plate through the control of multiple controllable switches. That is, the aerosol heating component and the aerosol heating control device can be electrically connected at any angle, thereby reducing the installation difficulty of the aerosol generation equipment and improving the installation convenience.

[0041] In an optional implementation of this embodiment, such as Figure 3 As shown, the control unit 10 designed in this scheme may include a controller 110 and a memory 120. The controller 110 is electrically connected to the memory 120, and the controller 110 is electrically connected to each controllable switch k1 and each connection electrode 410. The memory 120 stores the open-circuit electrical information of the connection electrode when the connection is open. The controller 110 can collect the current electrical information of each connection electrode 410, and then the controller 110 can compare the current electrical information of each connection electrode 410 with the open-circuit electrical information, and finally identify the connection electrode whose current electrical signal is not an open-circuit electrical signal as the target electrode. The electrical signal can include any one or more of voltage, capacitance, resistance, and inductance signals. For example, the controller 110 can compare whether the current voltage value of each connected electrode 410 is an open-circuit voltage value. If the current voltage value is an open-circuit voltage value, it means that the connected electrode 410 is in an open-circuit state and is not connected to the electrical contact N1. If the current voltage value is not an open-circuit voltage value, it means that the connected electrode 410 is not in an open-circuit state and is connected to the electrical contact N1, thereby determining that it is the target electrode.

[0042] The controller 110 can obtain the open-circuit electrical information of the connection electrode 410 by reading the target storage address in the memory 120. In this design, all connection electrodes 410 can be of the same size, thus ensuring that the open-circuit electrical information of each connection electrode 410 is also the same, thereby reducing the processing complexity of the controller 110 and improving its processing efficiency.

[0043] In the above implementation, the control unit uses the method of reading the open circuit electrical information stored in the memory and comparing it with the current electrical information of the connected electrode to realize the identification of the target electrode and control of the switching unit, thereby improving the processing efficiency of the controller and reducing the computational complexity of the controller.

[0044] In an optional embodiment of this scheme, the multiple connecting electrodes 410 designed in this scheme can be disposed on the surface area of ​​the connecting component 40, wherein the area of ​​the surface area occupied by each connecting electrode is less than half of the surface area, so that the included angle of each connecting electrode is less than 180°, ensuring that the electrical contacts of the aerosol heating component are not connected to the same connecting electrode, thereby improving the reliability of the contact connection between the electrical contacts of the aerosol heating component and the electrode.

[0045] Furthermore, such as Figure 4 As shown, the connection assembly 40 designed in this scheme may further include a circular connection plate 420, and the number of connection electrodes 410 is three. The three connection electrodes divide the circular connection plate 420 into three equal parts. Specifically, the three connection electrodes 410 are disposed on three connection areas that divide the circular connection plate 420 into three equal parts, with the center of the circular connection plate 420 as the center. For example, the three connection electrodes 410 may specifically be electrode A, electrode B, and electrode C. The connection plate of the connection assembly 40 designed in this scheme, in addition to using... Figure 4 Besides the solid circular connecting plate and the evenly distributed electrodes shown, connecting plates of other geometric shapes can also be used, and electrodes can be unevenly distributed, for example, as shown. Figure 5 The example shown uses a circular connecting plate with evenly distributed electrodes; for example, such as... Figure 6 The connecting plate is a regular quadrilateral shape, and the electrodes are not evenly distributed.

[0046] As described above, the electrical contact N1 of the aerosol heating component N can be electrically connected to at least two target electrodes of the connecting component 40. As one possible implementation, the electrical contact N1 of the aerosol heating component N can be electrically connected to two target electrodes in the connecting component 40. Following the example above, the three connecting electrodes 410 can specifically be electrode A, electrode B, and electrode C, as shown below. Figure 4As shown, the electrical contact N1 of the aerosol heating component N can be connected to the electrodes A and B of the connecting component 40, i.e., electrodes A and B are the target electrodes. In this case, the controller 110 controls the controllable switches k1 connected to electrodes A and B respectively to close, so that the heating power supply unit 20 forms a conductive circuit with the aerosol heating component N through electrodes A, electrodes B and electrical contact N1, thereby supplying power to the aerosol heating component N, so that the aerosol heating component N can heat the aerosol matrix inside to generate aerosol.

[0047] As another possible implementation, the electrical contact N1 of the aerosol heating component N can be electrically connected to two or more target electrodes in the connecting component 40. Following the example above, the three connecting electrodes 410 can specifically be electrode A, electrode B, and electrode C, as shown below. Figure 7 As shown, one of the two electrical contacts N1 of the aerosol heating component N is connected to electrode B, and the other electrical contact is simultaneously connected to electrodes A and C of the connecting component 40 (e.g., the electrical contact is located between electrodes A and C). At this time, electrodes A, B, and C are all target electrodes. In this case, the controller 110 controls the controllable switches k1 connected to electrodes A, B, and C to close, thereby enabling the heating power supply unit 20 to form a conductive circuit with the aerosol heating component N through electrodes A, B, C, and electrical contact N1, thereby supplying power to the aerosol heating component N, and enabling the aerosol heating component N to heat the aerosol matrix inside to generate aerosol.

[0048] In an optional embodiment of this invention, when the number of connected electrodes is three, the connection configuration of the heating power supply unit 20 and the multiple connected electrodes 410 designed in this scheme can be specifically adopted as follows: Figure 8 As shown, the heating power supply unit 20 outputs a DC voltage (e.g., 5V), with its positive output being V+ and its negative output being GND. The three electrodes can be electrode A, electrode B, and electrode C. Electrode A is connected to the positive output V+. Electrode B is connected to the negative GND through diode D1, where the anode of diode D1 is connected to electrode B and the cathode of diode D1 is connected to the negative GND. Electrode C is connected to the negative GND through diode D2, where the anode of diode D2 is connected to electrode C and the cathode of diode D2 is connected to the negative GND. A current-limiting resistor R (e.g., 1kΩ) is connected in series between electrode B and electrode C to prevent short circuit when electrode B and electrode C are connected.

[0049] In the above implementation scheme, it is assumed that the electrical contact N1 of the aerosol heating component includes two electrical contacts P and Q, where P and Q are connected to any two electrodes: Electrical contact P is connected to electrode A, and electrical contact Q is connected to electrode B. At this time, controller 110 controls the controllable switch k1 corresponding to electrode A and electrode B to close. Electrode A is connected to the positive terminal V+, and electrode B is connected to the negative terminal GND through diode D1. There is a voltage between electrode A and electrode B (V+ to GND), and the circuit is effective.

[0050] Electrical contact P is connected to electrode A, and electrical contact Q is connected to electrode C. At this time, controller 110 controls the controllable switch k1 corresponding to electrode A and electrode C to close. Electrode A is connected to the positive terminal V+, and electrode C is connected to the negative terminal GND through diode D2. There is a voltage between electrode A and electrode C (V+ to GND), and the circuit is effective.

[0051] Electrical contact P is connected to electrode B, and electrical contact Q is connected to electrode C. At this time, controller 110 controls the controllable switch k1 corresponding to electrode B and electrode C to close. Electrode B goes to electrode C through current-limiting resistor R, and electrode C goes to the negative terminal GND through diode D2. The potential of electrode B is higher than that of electrode C (when diodes D1 and D2 are forward-biased, both electrode B and electrode C are close to GND, but there is a small voltage difference in current-limiting resistor R, and the forward voltage drop of diodes D1 and D2 makes electrode B higher than electrode C), thus meeting the power supply requirements.

[0052] When P is connected to one electrode and Q is connected to the other two electrodes: Electrical contact P is connected to electrode A, and electrical contact Q is connected to electrodes B and C. Electrode B is connected to the negative terminal GND through diode D1, and electrode C is connected to the negative terminal GND through diode D2. Electrodes B and C are equivalent to the negative terminal GND. Since electrical contact P is connected to electrode A, it is equivalent to connecting to the positive terminal V+. Therefore, there is a voltage between electrical contact P and electrical contact Q, and the circuit is effective.

[0053] Electrical contact P is connected to electrode B, and electrical contact Q is connected to electrodes A and C. Since electrical contact Q is connected to both electrodes A and C, the potential of electrical contact Q is close to the positive terminal V+ (the high potential of electrode A dominates). Electrical contact P is connected to electrode B through diode D1 to the negative terminal GND. Therefore, there is a voltage between electrical contact Q (V+) and electrical contact P (GND), and the circuit is effective.

[0054] Electrical contact P is connected to electrode C, and electrical contact Q is connected to electrodes A and B. Since electrical contact Q is connected to both electrodes A and B, the potential of electrical contact Q is close to the positive terminal V+ (the high potential of electrode A dominates). Electrical contact P is connected to electrode C through diode D2 to the negative terminal GND. Therefore, there is a voltage between electrical contact Q (V+) and electrical contact P (GND), and the circuit is effective.

[0055] In the above implementation, this solution uses two diodes combined with one current-limiting resistor to achieve the connection of the heating power supply unit 20 and multiple connecting electrodes 410, thereby enabling the aerosol heating component and the connecting plate to be connected to the aerosol heating control device at any connection angle. That is, the aerosol heating component and the aerosol heating control device can be electrically connected at any angle. The circuit structure is simple and the reliability is high.

[0056] This application also provides an aerosol generating device, such as... Figure 9 As shown, the aerosol generating device includes an aerosol heating component N and an aerosol heating control device 1 according to any of the optional embodiments described above. The aerosol heating component N includes an aerosol matrix N2, a resistance heating element N3, and a plurality of electrical contacts N1. The resistance heating element N3 is electrically connected to the plurality of electrical contacts N1 and is configured to heat the aerosol in the aerosol matrix N2. The plurality of electrical contacts N1 are configured to be electrically connected to at least two target electrodes of the connection component 40 of the aerosol heating control device 1.

[0057] In the aerosol generation device designed above, multiple electrical contacts N1 of the aerosol heating component N can make contact with multiple connecting electrodes 410 of the aerosol heating control device 1 to achieve electrical connection. The connecting electrodes 410 connected to the electrical contacts N1 can be target electrodes. When multiple electrical contacts N1 are connected to at least two target electrodes, the control unit 10 of the aerosol heating control device 1 can control the switching unit 30 of the aerosol heating control device 1 to be turned on, forming a conducting circuit of heating power supply unit 20, at least two target electrodes, multiple electrical contacts N1 and resistance heating element N3, so that heating power supply unit 20 supplies power to resistance heating element N3, and resistance heating element N3 heats the aerosol in aerosol matrix N2 to generate aerosol.

[0058] The aerosol generation device designed above includes the aerosol heating control device described above. Therefore, the heating power supply unit of the aerosol generation device is connected in series with each connecting electrode of the connecting component through a switching unit. The control unit can control the switching unit so that when at least two target electrodes of the connecting component are electrically connected to the electrical contacts of the aerosol heating component, the switching unit is controlled to conduct and form a conducting circuit of the heating power supply unit, at least two target electrodes, and the aerosol heating component. This allows the aerosol heating component to achieve effective electrical connection with any electrode of the connecting component, that is, the aerosol heating component and the aerosol heating control device can be electrically connected at any angle, thereby reducing the installation difficulty of the aerosol generation device and improving the installation convenience.

[0059] In an optional embodiment of this example, the aerosol heating control device 1 further includes a receiving cavity 50, and a connecting component 40 is disposed at the first end of the receiving cavity 50; the aerosol heating component N is detachably disposed within the receiving cavity 50; wherein, a plurality of connecting electrodes 410 on the connecting component 40 face the opening of the receiving cavity 50, and a plurality of electrical contacts N1 are configured to be electrically connected to at least two target electrodes of the connecting component 40 when the aerosol heating component N is disposed within the receiving cavity 50.

[0060] In the above embodiment, the connecting component 40 is disposed in the receiving cavity 50, and the aerosol heating component N is detachably disposed in the receiving cavity 50 to achieve electrical connection with the connecting electrode on the connecting component 40. This ensures that after the aerosol heating component N is installed, its electrical contacts can stably connect with the connecting electrode of the connecting plate, avoiding power interruption or abnormal heating caused by poor contact.

[0061] Furthermore, the aerosol heating control device 1 designed in this scheme also includes an elastic element 60; the connecting assembly 40 is connected to the first end of the receiving cavity 50 through the elastic element 60. Specifically, the elastic element provided in this scheme can be a spring, a spring probe, a silicone buffer, etc.

[0062] The electrical contacts N1 and connecting electrode 410 of the aerosol heating component N may have slight dimensional deviations due to manufacturing tolerances. The elastic element 60 can fill the gaps by its own deformation to ensure tight contact between the two and avoid power interruption or poor contact caused by loosening. In addition, when the user inserts or removes the aerosol heating component N, the elastic element 60 can buffer the axial force to avoid wear caused by hard contact between the aerosol heating component N and the inner wall of the receiving cavity 50, thus extending the service life of the aerosol heating component N and the aerosol heating control device 1.

[0063] Furthermore, as described above, the connecting component 40 in this design is a circular connecting plate. In this case, the receiving cavity 50 of the aerosol heating control device 1 is also circular, and its size is adapted to the connecting component 40. The circular connecting plate and the circular inner wall of the receiving cavity 50 can fit perfectly. The three connecting electrodes 410 are evenly distributed along the circumference to make full use of the radial space and avoid local congestion caused by the concentrated distribution of connecting electrodes.

[0064] The above design ensures that regardless of the angle at which the aerosol heating component N is inserted into the receiving cavity 50, the multiple electrical contacts N1 of the aerosol heating component N can easily form effective contact with any two of the multiple connecting electrodes 410 on the connecting component 40. Furthermore, because the three connecting electrodes 410 on the connecting component 40 are symmetrically distributed, after the aerosol heating component N is inserted into the receiving cavity 50, the pressure exerted by the elastic element 60 on the connecting component 40 can be evenly distributed to the three connecting electrodes 410 through the 120° symmetrical structure, preventing excessive force (deformation) or insufficient force (loose contact) on any one electrode due to electrode distribution misalignment.

[0065] In an optional implementation of this embodiment, such as Figure 10 As shown, the resistance heating element N3 designed in this scheme includes an electrically insulating substrate N31 and a resistance heating rail N32. The resistance heating rail N32 is disposed on the electrically insulating substrate N31 and is electrically connected to multiple electrical contacts N1. Thus, the resistance heating rail N32 releases heat when energized, thereby heating the aerosol matrix. Furthermore, the electrically insulating substrate N31 protects the resistance heating rail N32 from corrosion by aerosol condensates (such as glycerol and propylene glycol in e-liquid) or oxygen in the air. Especially at high temperatures, the insulating substrate (such as ceramic) can form a physical barrier, delaying the oxidation and aging of the heating rail. In addition, this scheme can precisely control the heating power and temperature distribution by designing the shape and thickness of the resistance heating rail, ensuring that the aerosol matrix (such as e-liquid, solid tobacco, homogenized tobacco, etc.) is uniformly heated to the optimal volatilization temperature (300-400℃), avoiding localized overheating leading to scorching or insufficient temperature affecting aerosol production.

[0066] In an optional embodiment of this invention, the shape of the electrically insulating substrate N31 designed in this scheme includes any one of the following: rod, needle, pin, blade, or cone.

[0067] In the above embodiments, the electrically insulating substrate designed in this scheme is in the shape of a rod, needle, or pin that can be directly inserted into or penetrate the interior of the matrix (similar to a "probe"). After the resistance heating rails N32 are distributed on the surface of the substrate, they can conduct heat from the center of the matrix outward, avoiding the problem of "overheating of the outer layer and insufficient heating of the inner layer" in traditional surface heating. The slender shape of the electrically insulating substrate N31, such as rod, needle, or pin, can concentrate the resistance heating rails N32 on the axial surface, making the radial diffusion of heat to the surrounding matrix more uniform and reducing axial heat conduction to the outer shell. This is especially suitable for scenarios that require local high temperatures.

[0068] In this design, the electrically insulating substrate is cone-shaped, allowing its tip to easily penetrate a dense aerosol matrix. The cone-shaped structure at the bottom expands the contact area with the aerosol matrix, balancing ease of insertion and heating coverage. This design is suitable for solid aerosol matrices with high hardness (such as compressed smoke blocks).
