At the same time, the term "and / or" used in this specification includes any and all combinations of the related listed items.

[0040] The atomization device provided by the embodiments of the present application can be applied to an atomization device. When the atomization device is working, it can generate heat, thereby heating the aerosol generating matrix. After the temperature of the aerosol generating matrix reaches the boiling point, it is atomized to form an aerosol.

[0041] In one embodiment, as Figure 1As shown in the figure, an atomizing device is provided, which includes a sampling module 100, at least two heating modules 200, and a control module 300. The heating module 200 generates heat during operation. The sampling module 100 is connected to each heating module 200 and is used to sample the operating parameters of multiple heating modules 200. When the heating module 200 generates heat, it can heat the aerosol generation matrix to atomize it and generate aerosol. The sampling module 100 can sample the operating parameters of multiple heating modules 200, and then the control module 300 controls the heating of the heating module 200 according to the operating parameters. Thus, through one sampling module 100, the operating parameters of multiple heating modules 200 can be sampled, reducing the complexity of wiring and the volume, which is beneficial to reducing the volume of the PCB board.

[0042] Specifically, the heating module 200 generates heat during operation. The heating module 200 includes a heating element. When the heating module 200 is in the powered-on state, the heating element is powered and generates heat. Therefore, it is possible to control whether the heating module 200 is in the operating state by controlling whether the heating module 200 is powered on. The heating element can be a heating wire or the like, and the specific type is not limited. The number of heating modules 200 is more than two, for example, it can be two, three, four or other numbers. Further, each heating module 200 is connected in parallel, and each heating module 200 can operate independently. Different heating modules 200 can be used to heat different aerosol generation matrices, thereby providing various types and proportions of aerosols.

[0043] The number of sampling modules 100 is one, and the number of heating modules 200 is multiple. It can be understood that the connection relationship between the sampling module 100 and the heating module 200 is a one-to-many connection relationship, and one sampling module 100 is connected to multiple heating modules 200. The heating module 200 in the operating state is in the powered-on state, generates heat during operation, and is conducted with the sampling module 100. The sampling module 100 samples the heating module 200 conducted with it and detects its operating parameters. Among them, the type of operating parameters is not unique. For example, it can be resistance, voltage, etc.

[0044] The sampling module 100 and each heating module 200 are both connected to the control module 300. The control module 300 serves as the central control device of the atomization device. The sampling module 100 is connected to the control module 300 and can send the sampling result to the control module 300, enabling the control module 300 to obtain the working parameters of the heating module 200. The control module 300 can also send control instructions to the sampling module 100 to control the working state of the sampling module 100, such as whether the sampling module 100 works and whether it is in the sampling state when working. The control module 300 is also connected to each heating module 200 and can send control instructions to each heating module 200 according to the working parameters of the heating module 200 to control whether each heating module 200 works and the heating power when working. It can be understood that in other embodiments, if the atomization device further includes other components, they can also be connected to the control module 300. The control module 300 can also be connected to components outside the atomization device to achieve information interaction between the atomization device and other components. The type of the control module is not unique. Exemplarily, in this embodiment, the control module is an MCU.

[0045] In one embodiment, the number of sampling modules is less than the number of heating modules. One sampling module can sample one or more heating modules. By reducing the number of sampling modules, the volume of the atomization device can be reduced. Further, the sampling control of the sampling module can be achieved through the heating control of the heating module. For example, by controlling the heating module to work and generate heat, the heating module can be conducted with the sampling module, so that the sampling module can sample the working parameters of the working heating module. Or, by controlling the heating module to stop working, the heating module can be disconnected from the sampling module, so that the sampling module does not sample the disconnected heating module.

[0046] Further, in one embodiment, the control module is further configured to control the sampling module to sample the working parameters of different heating modules at different time points.

[0047] Specifically, the control module can control only one heating module to work each time, so that the sampling module can only sample the working parameters of one heating module in a time period. By controlling different heating modules to work in different time periods, the sampling module can sample the working parameters of all heating modules. Thus, combined with the control of the control module, a sampling module can be used to sample the working parameters of all heating modules, which is beneficial to further reducing the wiring complexity and reducing the volume.

[0048] In one embodiment, as Figure 2As shown in the figure, the sampling module 100 includes a sampling resistor R15 and a sampling control switch tube Q12. The sampling control switch tube Q12 is connected to the sampling resistor R15, the control module, and the heating module. The control module is used to control whether the sampling resistor R15 is in the sampling state by controlling the on-off state of the sampling control switch tube Q12.

[0049] Specifically, the first end of the sampling control switch tube Q12 is connected to the first end of the sampling resistor R15, the second end of the sampling control switch tube Q12 is connected to the second end of the sampling resistor R15, and is connected to the heating module 200. The control end of the sampling control switch tube Q12 is connected to the control module.

[0050] The branch connecting the first end and the second end of the sampling resistor R15 can be understood as the first branch, and the branch connecting the first end and the second end of the sampling control switch tube Q12 can be understood as the second branch. That is to say, the sampling module 100 includes two different branches, and the sampling control switch tube Q12 can be understood as being connected in parallel with the sampling resistor R15.

[0051] When the control module controls the sampling control switch tube Q12 to conduct, the current flows through the sampling control switch tube Q12, and the sampling resistor R15 is short-circuited and no sampling is performed. When the control module controls the sampling control switch tube Q12 to turn off, the current flows through the sampling resistor R15 and the heating module 200, and the sampling resistor R15 can sample the working parameters of the heating module 200. The sampling resistor R15 can be connected to the control module, and the control module obtains the working parameters sampled by the sampling resistor R15 for subsequent control steps. In this embodiment, the working parameter can be a resistance. The resistance value of the sampling resistor R15 can be determined according to actual needs. Exemplarily, the resistance value of the sampling resistor R15 can be 4.7Ω.

[0052] The control module is connected to the control end of the sampling control switch tube Q12, and can control the sampling control switch tube Q12 to conduct or turn off by sending high and low level signals to the control end of the sampling control switch tube Q12. The type of the sampling control switch tube Q12 is not limited. For example, it can be a MOS tube or a triode, etc., as long as those skilled in the art think it can be realized.

[0053] In this embodiment, the sampling module 100 includes a sampling resistor R15 and a sampling control switch tube Q12. The control module can control whether the sampling module 100 performs sampling by controlling the on-off state of the sampling control switch tube Q12, thereby controlling the working state of the sampling module 100.

[0054] In one embodiment, as Figure 2As shown, the sampling module 100 further includes a power control switch tube Q11 connecting the sampling resistor R15 and the sampling control switch tube Q12. The power control switch tube Q11 is connected to the power supply, and the control module is used to control whether the sampling resistor R15 and the sampling control switch tube Q12 are powered on by controlling the on / off state of the power control switch tube Q11.

[0055] Specifically, the first end of the power control switch tube Q11 is connected to the power supply, the second end of the power control switch tube Q11 is connected to the first end of the sampling resistor R15, and the control end of the power control switch tube Q11 is connected to the control module.

[0056] The control module is connected to the control end of the power control switch tube Q11 and can control the on / off state of the power control switch tube Q11 by sending high and low level signals to the control end of the power control switch tube Q11. When the power control switch tube Q11 is turned on, the connected power supply can reach the sampling resistor R15 or the sampling control switch tube Q12 and then conduct with the heating module 200. When the power control switch tube Q11 is turned off, both the sampling resistor R15 and the sampling control switch tube Q12 are in a power-off state. When the heating module 200 depends on the power supply connected from the power control switch tube Q11, the heating module 200 is also in a power-off state. In this case, the atomizing device is in a standby state or a stop heating state. The type of the power control switch tube Q11 is not limited. For example, it can be a MOS tube or a triode, etc., as long as those skilled in the art think it can be achieved.

[0057] In this embodiment, the sampling module 100 further includes a power control switch tube Q11, and the control module can control whether the whole atomizing device is in a standby state or a stop heating state by controlling the on / off state of the power control switch tube Q11.

[0058] In one embodiment, as Figure 3 shown, the heating module 200 includes a heating control circuit 210 and a heating element. The heating control circuit 210 is connected to the sampling module 100 and the first end of the heating element, and the second end of the heating element is grounded.

[0059] It can be understood that in this embodiment, each heating module 200 includes a heating control circuit 210 and a heating element. The sampling module 100 is connected to each heating module 200, and the sampling module 100, the heating control circuit 210 and the heating element in one heating module 200 are connected in series in sequence. When a certain heating control circuit 210 is turned on, the sampling module 100, the turned-on heating control circuit 210 and the heating element are turned on. If the sampling module 100 is turned on, the heating element is powered on and in a working state; if the sampling resistor R15 of the sampling module 100 is turned on, the heating element is in a working state, and the sampling resistor R15 can perform resistance sampling on the heating module 200 where the turned-on heating control circuit 210 is located.

[0060] Extensibly, the heating control circuit 210 is connected to a control module, and the control module can control the heating control circuit 210 to be in an on or off state by sending different control instructions to the heating control circuit 210, so as to control whether the heating element works, and can also control the on-time of the heating control circuit 210, etc.

[0061] In this embodiment, the heating module 200 includes a heating control circuit 210 and a heating element. The heating control circuit 210 is used to control whether the heating element works. The heating element generates heat when working to achieve the heating function.

[0062] The structure of the heating control circuit 210 is not unique. In one embodiment, as Figure 3 shown, the heating control circuit 210 includes a heating control switching tube (Q9, Q10 or Q13). The first end of the heating control switching tube is connected to the sampling module 100, the second end of the heating control switching tube is connected to the first end of the heating element, and the control end of the heating control switching tube is connected to the control module.

[0063] The control module is connected to the control end of the heating control switching tube and can control the heating control switching tube to be turned on or off by sending high and low level signals to the control end of the heating control switching tube. When the heating control switching tube is turned on, the first end and the second end of the heating control switching tube are turned on, and the sampling module 100 and the heating element are turned on. When the sampling module 100 is successfully connected to the power supply, the connected power supply can reach the heating element, and the heating element is powered on and works. When the heating control switching tube is turned off, the heating element loses power and stops working. It can be understood that in other embodiments, the heating control circuit 210 can also be other structures as long as those skilled in the art think it can be achieved. The type of the heating control switching tube is not limited. For example, it can be a MOS tube or a triode, etc., as long as those skilled in the art think it can be achieved.

[0064] In this embodiment, the heating control circuit 210 includes a heating control switching tube. The first end of the heating control switching tube is connected to the sampling module 100, the second end of the heating control switching tube is connected to the first end of the heating element, and the control end of the heating control switching tube is connected to the control module. The control module can control whether the heating element is powered on through the conduction state of the heating control switching tube, so as to control whether the atomizing device is in a heating state.

[0065] In one embodiment, as Figure 3 shown, the heating module 200 further includes a ground control switching tube Q8 connected between the heating element and the control module. The control module is configured to control whether the heating element is grounded by controlling the on / off state of the ground control switching tube Q8.

[0066] Specifically, the first end of the ground control switching tube Q8 is connected to the second end of the heating element, the second end of the ground control switching tube Q8 is grounded, and the control end of the ground control switching tube Q8 is connected to the control module.

[0067] The control module is connected to the control end of the ground control switching tube Q8 and can control the ground control switching tube Q8 to conduct or turn off by sending high and low level signals to the control end of the ground control switching tube Q8, so as to control whether the heating element is grounded. When the ground control switching tube Q8 conducts, the first end and the second end of the ground control switching tube Q8 conduct, and the heating element is grounded. When the heating element is connected to the power supply, it can be powered on and work. When the ground control switching tube Q8 is turned off, the heating element cannot be grounded and stops working regardless of whether the heating element is connected to the power supply. The type of the ground control switching tube Q8 is not limited. For example, it can be a MOS tube or a triode, etc., as long as those skilled in the art think it can be realized.

[0068] In this embodiment, the heating module 200 further includes a ground control switching tube Q8. The first end of the ground control switching tube Q8 is connected to the second end of the heating element, the second end of the ground control switching tube Q8 is grounded, and the control end of the ground control switching tube Q8 is connected to the control module. The control module can quickly control whether the heating element is powered on by controlling the conduction state of the ground control switching tube Q8, so as to control whether the atomizing device is in a heating state.

[0069] In one embodiment, a method for controlling an atomizing device is provided, which is implemented based on the atomizing device in any of the above embodiments. As Figure 4 shown, the method for controlling an atomizing device can be executed by the control module and includes the following steps:

[0070] Step 402, the control module receives a control instruction.

[0071] Among them, the control instruction can be generated according to the user instruction received by the control module, enabling the atomization device to work on demand. Alternatively, the control instruction can also be generated according to the preset data and the collected data. For example, when the preset data includes the preset heating duration and the collected data includes the actual heating duration, the control module receives the actual heating duration. When the actual heating duration reaches the preset heating duration, a control instruction can be generated. At this time, the control instruction is a stop heating instruction.

[0072] Step 404, if the control instruction includes a sampling instruction or a heating instruction, perform heating control on the heating module according to the heating instruction.

[0073] Among them, the sampling instruction is used to indicate that the sampling module needs to work, and the heating instruction is used to indicate that the heating module needs to work.

[0074] If the control module receives a heating instruction, it performs heating control on the heating module according to the heating instruction to control the corresponding heating module to work. Specifically, the heating instruction includes the heating object, and the control module selects the heating instruction to control the heating module corresponding to the heating object to work. Extensibly, the heating instruction can also include the heating power, etc., and the control module can control the heating power of the heating module according to the heating power in the heating instruction.

[0075] Step 406, control the sampling module to sample the working parameters of multiple heating modules according to the sampling instruction.

[0076] If the control module receives a sampling instruction, it controls the sampling module to be in the sampling state and samples the working parameters of multiple heating modules.

[0077] In this embodiment, after receiving the control instruction, if the control instruction includes a sampling instruction or a heating instruction, control the corresponding heating module to work according to the heating instruction, and control the sampling module to sample the working parameters of the heating module in the working state according to the sampling instruction, so as to realize the heating control of the heating module and the sampling control of the sampling module.

[0078] In one embodiment, as Figure 5 shown, step 406 includes step 506: control the sampling module to sample the working parameters of different heating modules at different time points according to the sampling instruction.

[0079] Specifically, the control module can control only one heating module to work each time, so that the sampling module can only sample the working parameters of one heating module in a time period. By controlling different heating modules to work in different time periods, the sampling module can sample the working parameters of all heating modules. Thus, combined with the control of the control module, all heating module working parameters can be sampled by one sampling module, which is beneficial to further reducing the wiring complexity and reducing the volume.

[0080] In one embodiment, the sampling module 100 includes a sampling resistor R15 and a sampling control switch tube Q12, and step 406 includes the step of controlling the sampling control switch tube Q12 to turn off according to a sampling instruction.

[0081] Specifically, when the sampling module 100 includes a sampling resistor R15 and a sampling control switch tube Q12, if the control module receives a sampling instruction, it controls the sampling control switch tube Q12 to turn off, so that the current flows through the sampling resistor R15, and the sampling resistor R15 samples the operating parameters of the connected heating module 200.

[0082] Further, if the sampling device further includes a power control switch tube Q11, a heating control switch tube, and a ground control switch tube Q8, then if the control module receives a sampling instruction, it controls the power control switch tube Q11, the heating control switch tube, and the ground control switch tube Q8 to all conduct, so that the sampling module 100 is connected to the power supply, the heating module 200 is turned on, and the heating element is turned on, facilitating the sampling resistor R15 to sample the operating parameters of the turned-on heating module 200.

[0083] In this embodiment, if the sampling module 100 includes a sampling resistor R15 and a sampling control switch tube Q12, the control module controls the sampling control switch tube Q12 to turn off according to the sampling instruction, so that the current flows through the sampling resistor R15, and the sampling resistor R15 samples the operating parameters of the connected heating module 200.

[0084] In one embodiment, after step 402, the atomizing device control method further includes the step of: if the control instruction includes a standby instruction or a stop heating instruction, controlling the heating module to stop working.

[0085] If the control module receives a standby instruction or a stop heating instruction, considering that the whole machine does not need to be heated at this time, it controls all the heating modules 200 to stop working, so that the atomizing device is in a standby state or in a stop heating state.

[0086] Further, if the heating module 200 includes a heating control circuit 210 and a heating element, after the control module receives a standby instruction or a stop heating instruction, it can control all the heating control circuits 210 to disconnect, so that the atomizing device is in a standby state or in a stop heating state.

[0087] Alternatively, when the atomizing device further includes a power control switch tube Q11 and a ground control switch tube Q8, after the control module receives a standby instruction or a stop heating instruction, it can control the power control switch tube Q11 and the ground control switch tube Q8 to turn off. At this time, the heating module 200 can be not controlled, and the atomizing device can also be in a standby state or in a stop heating state.

[0088] In this embodiment, if the control instruction includes a standby instruction or a stop heating instruction, the heating module 200 is controlled to stop working to meet the user's needs.

[0089] In one embodiment, an atomizing device is provided, including the atomizing device of any of the above embodiments. Exemplarily, a plurality of atomizing chambers are formed in the atomizing device, and each heating module 200 can be disposed in a different atomizing chamber.

[0090] To better understand the above embodiments, the following will be explained in detail with a specific embodiment. In one embodiment, as Figures 1-3 shown, the atomizing device includes a sampling module 100, a control module 300, and three heating modules 200. Among them, as Figure 6 shown, the control module is an MCU. The sampling module 100 includes a sampling resistor R15, a sampling control switch tube Q12, and a power control switch tube Q11, and further includes a resistor R18 that cooperates with the sampling control switch tube Q12 and a resistor R17 that cooperates with the power control switch tube Q11. The heating module 200 includes a heating control circuit 210, a heating element, and a ground control switch tube Q8. The heating control circuit 210 includes a heating control switch tube, and resistors R13, R16, and R19 that cooperate with the heating control switch tube.

[0091] Among them, the sampling resistor R15 is a 4.7Ω resistor in 0805 package. The sampling control switch tube Q12 is a P-type MOS tube and is connected in parallel with the sampling resistor R15. The power control switch tube Q11 is a P-type MOS tube and is connected in series with the sampling resistor R15. ADC3 is the sampling module interface and is connected to the sampling Pin of the MCU. The heating control switch tubes Q9, Q10, and Q13 are all P-type MOS tubes and respectively control the heating output of the three heating elements. The ground control switch tube Q8 is a P-type MOS tube.

[0092] The atomizing device control method includes: when in standby or stop heating, the timing diagram is as Figure 7 shown. The control pin Heat_ON1 of the power control switch tube Q11 is set to high level, and the power control switch tube Q11 is turned off; the control pin of the ground control switch tube Q8 is set to high level, and the ground control switch tube Q8 is turned off, and the heating element does not heat.

[0093] When heating, the timing diagram is as Figure 8, the control pin Heat_ON1 of the power control switch transistor Q11 is set to a low level, and the power control switch transistor Q11 conducts; the control pin 4R7_ON1 of the sampling control switch transistor Q12 is set to a low level, the sampling control switch transistor Q12 conducts, and the sampling resistor R15 is short-circuited; the control pin of the ground control switch transistor Q8 is set to a low level, and the ground control switch transistor Q8 conducts. The heating control switch transistors Q9, Q10, and Q13 can be controlled to conduct or turn off synchronously or asynchronously according to the heating mode, so as to control the heating of the three heating elements.

[0094] When detecting the hot-state resistance value of the heating element, the timing diagram is as Figure 9 shown. The control pin Heat_ON1 of the power control switch transistor Q11 is set to a low level, and the power control switch transistor Q11 conducts; the control pin 4R7_ON1 of the sampling control switch transistor Q12 is set to a high level, the sampling control switch transistor Q12 turns off, and the current passes through the sampling resistor R15; the control pin of the ground control switch transistor Q8 is set to a low level, and the ground control switch transistor Q8 conducts. The heating control switch transistors Q9, Q10, and Q13 are respectively asynchronously turned on by setting the control pins low, and the hot-state resistance values of the respective heating elements are measured.

[0095] In the above atomizing device and its control method, by connecting an MOS transistor in parallel with a 4.7Ω sampling resistor and then connecting two or more parallel heating modules in series, it is possible to sample the hot-state resistance values of multiple heating elements with only one sampling resistor. This saves the sampling resistor and related control circuits, saving material costs. It saves the PCB wiring space, can reduce the PCB area, and saves the PCB cost. It saves the ADC pins and GPIO pin resources of the MCU, reduces the functional requirements for the MCU, and saves the costs related to the MCU.
