Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.
[0030] The terms "first", "second", etc. in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0032] The disadvantage is that in the related art, there are still relatively large problems with how to optimize the communication or electrical connection between the data recording circuit in the atomizer module and the host end.
[0033] Based on this, the present application proposes to couple the data input / output pins of the data recording circuit to the first end of the atomizing component in the atomizer module, and the data input / output pins of the data recording chip and the host end of the atomizing device perform data interaction through the negative electrode of the atomizing component, so as to realize the function multiplexing of the negative electrode of the atomizing component, thereby eliminating the need to additionally set corresponding electrodes for the data recording chip on the host end and the atomizer module, simplifying the circuit and saving circuit costs. Further, the first path end of the switch circuit is coupled to the first end of the atomizing component, the lead wire of the second path end of the switch circuit serves as the positive electrode of the atomizing component, and the lead wire of the control end of the switch circuit serves as the negative electrode of the atomizing component. By utilizing the on-off characteristics of the switch circuit, the negative electrode is used to reasonably conduct and cut off the positive electrode side, ensuring the quality of data interaction between the data recording chip and the host end.
[0034] For details, please refer to Figure 1 , Figure 1 which is a schematic structural diagram of an embodiment of the data recording circuit provided by the present application. The data recording circuit 100 is disposed in the atomizer module of the electronic atomizing device.
[0035] The data recording circuit 100 includes: a data recording chip 10 and a switch circuit 20.
[0036] The data recording chip 10 has data input / output pins RSD. The data input / output pins RSD are coupled to the first end of the atomizing component 200 in the atomizer module.
[0037] The switch circuit 20 has a control end a, a first path end b and a second path end c, and the control end a controls the connection between the first path end b and the second path end c.
[0038] The control end a of the switch circuit 20 is coupled to the second end of the atomizing component 200, the first path end b of the switch circuit 20 is coupled to the first end of the atomizing component 200, the lead wire of the second path end c of the switch circuit 20 serves as the positive electrode of the atomizing component 200, and the lead wire of the control end a of the switch circuit 20 serves as the negative electrode of the atomizing component 200; wherein, the data input / output pins RSD of the data recording chip 10 and the host end of the electronic atomizing device perform data interaction through the negative electrode of the atomizing component 200.
[0039] In a typical embodiment, the atomizing component 200 is a section of heating wire, which can be connected to the circuit to form a loop with the power supply without direction distinction.
[0040] The data mentioned above can be the usage situation of the atomizer module. For example, a corresponding volume of atomizing matrix is provided in the atomizer module. This data can record the usage situation of the atomizing matrix. For example, the usage situation can be information such as the usage times, remaining usage times, and / or remaining volume of the atomizing matrix.
[0041] Combined Figure 2 The description is as follows:
[0042] After the electronic atomization device and the atomizer module are electrically connected, when the air flow sensor in the electronic atomization device detects that the ambient negative pressure is greater than the threshold, it sends a corresponding trigger signal to the controller in the electronic atomization device, so that the controller controls the power supply to supply power to the atomizer module. Specifically, the controller controls the power supply to supply power to the atomization component 200, and then uses the atomization component 200 to heat and atomize the atomization matrix.
[0043] Among them, during the atomization process, the current provided by the power supply arranged in the electronic atomization device can pass through a pair of contacts of the atomizer module, flow through one of the contacts, the second path end c of the switch circuit 20, and the first path end b to the atomization component 200, and then flow back to the power supply from the negative electrode and the other contact, so as to realize the atomization function of the atomization component 200. Further, the controller in the electronic atomization device will synchronously calculate the usage of the atomization matrix according to the relevant information of the atomization component 200. Thus, after the atomization ends, the controller of the host end of the electronic atomization device writes the usage of the atomization matrix into the data recording chip 10 for storage through the negative electrode of the atomization component 200, the atomization component 200, and the data input / output pin RSD of the data recording chip 10. The specific flow direction can be referred to Figure 2 Arrow B in
[0044] Similarly, thus before the atomization is started, the controller of the host end of the electronic atomization device reads the usage data of the atomization matrix stored in the data recording chip 10 through the negative electrode of the atomization component 200, the atomization component 200, and the data input / output pin RSD of the data recording chip 10. The specific flow direction can be referred to Figure 2 Arrow A in . That is, in some embodiments, the input and output of the data recording chip 10 communicating with the host end use the same line. Of course, in other embodiments, the input and output of the data recording chip 10 communicating with the host end can use different lines. For example, the data recording chip 10 can include separate data input ports and data output ports. After these two ports are led out from the data recording chip, they are gated through switching devices. The data input port communicates with the host end through the A path, and the data output port communicates with the host end through the B path.
[0045] Further, since the controller of the host end of the electronic atomization device interacts with the data recording chip 10 through the negative electrode of the atomization component 200, the atomization component 200, and the data input / output pin RSD of the data recording chip 10, and the lead wire of the second path end c of the switch circuit 20 serves as the positive electrode of the atomization component 200, in order to prevent the switch circuit 20 from affecting the data interaction between the controller of the host end of the electronic atomization device and the data recording chip 10 in the conducting state, during the data interaction process, the first path end b and the second path end c of the switch circuit 20 are not connected, and the switch circuit 20 is in the cut-off state. That is, during the data interaction process, the data current passing through the data input / output pin RSD of the data recording chip 10 does not flow to the second path end c of the switch circuit 20.
[0046] In some embodiments, the data recording chip 10 further includes a ground pin GND. The ground pin GND is coupled to the lead wire of the second path end c of the switch circuit 20. That is, the ground pin of the data recording chip 10 can use the positive electrode lead wire as the common ground end to form a loop. As Figure 1 shown, the branch formed by the data input / output pin RSD and the ground pin GND of the data recording chip 10 is in parallel with the branch formed by the first path end b and the second path end c of the switch circuit 20.
[0047] When the power supply of the host end supplies power to the atomization component, the current flows from the positive electrode through the switch circuit, the atomization component, the negative electrode, and then returns to the power supply.
[0048] When the host end communicates with the atomizer module, from the negative electrode, the atomization component, the data input / output pin RSD, and the data recording chip, when this path is used as the power supply of the data recording chip 10 or communicates with the chip, the ground pin GND of the data recording chip 10 is connected to the positive electrode. It can be understood that the atomization component 200 is usually a heating wire and can be regarded as a wire in the circuit, without directionality. That is, the external contacts formed in the atomizer module for external electrical connection do not have polarity distinction, and only after being specifically connected to the power supply of the host end do they have positive and negative contact distinctions. In the loop formed in the atomizer module in this embodiment from the negative electrode, the atomization component 200, the data input / output pin RSD, the data recording chip 10, the ground pin GND to the positive electrode, the negative electrode and the positive electrode in this loop can be regarded as two contacts, and there is actually no polarity division. In the specific implementation, the negative electrode in the atomizer module is connected to the positive electrode of the power supply of the host end, and the positive electrode in the atomizer module is connected to the negative electrode of the power supply of the host end. In a further embodiment, the host end further includes a switching unit for switching the power supply direction of the power supply of the host end.
[0049] This circuit serves as the power supply circuit for the data recording chip 10. The current supplied is small, and the current flowing through the atomization component 200 is small, so the atomization component 200 will not operate. That is, although the atomization component 200 is located between the data input / output pin RSD and the negative electrode, the current flowing through the atomization component 200 is small and not sufficient to produce an atomization effect.
[0050] In addition, besides enabling the data recording chip 10 to be connected in parallel with it to achieve conduction and cutoff in different power supply directions, the switch circuit 20 can also isolate the data input / output pin RSD from the ground pin GND.
[0051] In this embodiment, the data input / output pin RSD of the data recording circuit 100 is coupled to the first end of the atomization component 200 in the atomizer module. The data input / output pin RSD of the data recording chip 10 and the host end of the atomization device perform data interaction through the negative electrode of the atomization component 200, realizing the function multiplexing of the negative electrode of the atomization component 200. In this way, there is no need to additionally set corresponding electrodes for the data recording chip 10 on the host end and the atomizer module, simplifying the circuit and saving circuit costs. Further, the first path end b of the switch circuit 20 is coupled to the first end of the atomization component 200, the lead-out wire of the second path end c of the switch circuit 20 serves as the positive electrode of the atomization component 200, and the lead-out wire of the control end a of the switch circuit 20 serves as the negative electrode of the atomization component 200. Utilizing the conduction and cutoff characteristics of the switch circuit 20, reasonable conduction and cutoff are performed from the negative electrode to the positive electrode side to ensure the quality of data interaction between the data recording chip 10 and the host end.
[0052] Refer to Figure 3 , Figure 3 FIG. is a schematic structural diagram of another embodiment of the data recording circuit provided by the present application. The data recording circuit 100 includes: a data recording chip 10, a switch circuit 20, and a voltage stabilizing diode D6.
[0053] The data input / output pin RSD of the data recording chip 10 is coupled to the first end of the atomization component 200 in the atomizer module.
[0054] The control end a of the switch circuit 20 is coupled to the second end of the atomization component 200, the first path end b of the switch circuit 20 is coupled to the first end of the atomization component 200, the lead-out wire of the second path end c of the switch circuit 20 serves as the positive electrode of the atomization component 200, and the lead-out wire of the control end a of the switch circuit 20 serves as the negative electrode of the atomization component 200. The ground pin GND of the data recording chip 10 is coupled to the lead-out wire of the second path end b of the switch circuit 20.
[0055] Among them, the data input / output pin RSD of the data recording chip 10 and the host end of the atomization device perform data interaction through the negative electrode of the atomization component 200.
[0056] The positive electrode of the voltage - stabilizing diode D6 is coupled to the second path end c of the switch circuit 20, and the negative electrode of the voltage - stabilizing diode D6 is coupled to the first path end b of the switch circuit 20. The interaction mode between the data recording circuit 100 and the host end can refer to any embodiment of the present application, which will not be elaborated here.
[0057] In this embodiment, the voltage - stabilizing diode D6 is used to protect the switch circuit 20 and the data recording chip 10, improving the overall safety.
[0058] Refer to Figure 4 , Figure 4 is a schematic structural diagram of another embodiment of the data recording circuit provided by the present application. The data recording circuit 100 includes: a data recording chip 10 and a switch circuit. Among them, the switch circuit includes a transistor Q1. The control terminal G of the transistor Q1 is coupled to the second end of the atomization assembly 200, the first path end S of the transistor Q1 is coupled to the first end of the atomization assembly 200, and the lead - out wire of the second path end D of the transistor Q1 serves as the positive electrode of the atomization assembly 200. The control terminal G of the transistor Q1 serves as the negative electrode of the atomization assembly 200. The ground pin GND of the data recording chip 10 is coupled to the lead - out wire of the second path end D of the transistor Q1.
[0059] In some embodiments, the transistor Q1 is a PMOS transistor. The gate of the PMOS transistor is coupled to the second end of the atomization assembly 200, the source of the PMOS transistor is coupled to the first end of the atomization assembly 200, and the lead - out wire of the drain of the PMOS transistor serves as the positive electrode of the atomization assembly.
[0060] In an application scenario, in combination with Figure 5 it is described as follows:
[0061] After the electronic atomization device and the atomizer module are electrically connected, when the airflow sensor in the electronic atomization device detects that the ambient negative pressure is greater than the threshold, it sends a corresponding trigger signal to the controller in the electronic atomization device, so that the controller controls the power supply to supply power to the atomizer module, and then the atomization assembly 200 is used to atomize the atomization matrix.
[0062] Among them, during the atomization process, the current provided by the power supply starts from the positive electrode, can flow through the second path end D and the first path end S of the transistor Q1 to the atomization assembly 200, and then flows back to the power supply from the negative electrode, thereby realizing the atomization function of the atomization assembly 200. Further, the controller in the electronic atomization device will synchronously calculate the usage situation of the atomization matrix according to the relevant information of the atomization assembly 200. Thus, after the atomization ends, the controller of the host end of the electronic atomization device writes the usage situation of the atomization matrix into the data recording chip 10 through the negative electrode of the atomization assembly 200, the atomization assembly 200, and the data input / output pin RSD of the data recording chip 10 for storage. The specific flow direction can refer to Figure 5 the arrow B in
[0063] Similarly, before the atomization is turned on, the controller of the main unit of the electronic atomization device reads the usage of the atomization matrix stored in the data recording chip 10 through the negative electrode of the atomization component 200, the atomization component 200, and the data input / output pin RSD of the data recording chip 10. For the specific flow direction, please refer to Figure 5 the arrow A in
[0064] Furthermore, since the controller of the main unit of the electronic atomization device exchanges data with the data recording chip 10 through the negative electrode of the atomization component 200, the atomization component 200, and the data input / output pin RSD of the data recording chip 10, and the second path terminal D of the transistor Q1 serves as the positive electrode of the atomization component 200, in order to prevent the switch circuit 20 in the conducting state from affecting the data interaction between the controller of the main unit of the electronic atomization device and the data recording chip 10, during the data interaction process, the transistor Q1 is in the cut-off state. That is, the data current through the data input / output pin RSD of the data recording chip 10 does not flow to the second path terminal of the switch circuit 20.
[0065] In addition to the normal conduction and cut-off, the main function of the transistor Q1 is that during the data interaction process, since data is exchanged through the negative electrode, it is necessary to utilize the two ends of the transistor Q1 at the positive electrode to be in the cut-off state so that data does not flow out from the positive electrode. Based on this, using the characteristic of the PMOS transistor that it conducts when the input is at a low level and cuts off when the input is at a high level, when data is being exchanged, the transistor is controlled to cut off, and data can be successfully written to or read from the data recording chip 10.
[0066] In this embodiment, the data input / output pin RSD of the data recording circuit 100 is coupled to the first end of the atomization component 200 in the atomizer module, and the data input / output pin RSD of the data recording chip 10 exchanges data with the main unit of the atomization device through the negative electrode of the atomization component 200, realizing the function multiplexing of the negative electrode of the atomization component 200. In this way, there is no need to additionally set corresponding electrodes for the data recording chip 10 on the main unit and the atomizer module, simplifying the circuit and saving circuit costs. Furthermore, the first path terminal S of the transistor Q1 is coupled to the first end of the atomization component 200, the lead-out wire of the second path terminal D of the transistor Q1 serves as the positive electrode of the atomization component 200, and the lead-out wire of the control terminal G of the transistor Q1 serves as the negative electrode of the atomization component 200. By utilizing the conduction and cut-off characteristics of the transistor Q1, the negative electrode is used to reasonably conduct and cut off the positive electrode side, ensuring the quality of data interaction between the data recording chip 10 and the main unit.
[0067] Refer to Figure 6 , Figure 6It is a schematic structural diagram of an embodiment of the atomizer module provided by the present application. The atomizer module 300 includes a data recording circuit 100. The data recording circuit 100 is the data recording circuit 100 in any embodiment of the present application. Among them, the atomizer module 300 includes at least two contacts. At least one contact is connected to the positive electrode of the atomization component in the atomizer module 300, at least one contact is connected to the negative electrode of the atomization component in the atomizer module 300, and a circuit is formed between at least two contacts.
[0068] Refer to Figure 7 , Figure 7 It is a schematic structural diagram of another embodiment of the atomizer module provided by the present application. The atomizer module includes a data recording circuit 100 and an atomization component 200. Among them, the atomization component 200 includes a first atomization member 201 and a second atomization member 202, and the first atomization member 201 and the second atomization member 202 share a negative electrode. That is, the first atomization member 201 and the second atomization member 202 can realize a dual atomization function.
[0069] In some embodiments, the contacts corresponding to the negative electrode are spaced apart at the center between the contacts corresponding to the positive electrode of the first atomization member 201 and the contacts corresponding to the positive electrode of the second atomization member 202; among them, the first path end b of the switch circuit 20 is coupled to the first end of the first atomization member 201, and the lead wire of the second path end c of the switch circuit 20 serves as the positive electrode of the first atomization member 201.
[0070] Combined with Figure 8 for illustration:
[0071] The contact 1 corresponding to the negative electrode is spaced apart at the center between the contact 2 corresponding to the positive electrode of the first atomization member and the contact 3 corresponding to the positive electrode of the second atomization member. That is, as Figure 8 shown, the contact 1, the contact 2, and the contact 3 are on the same plane, and the distance l1 from the contact 1 to the contact 2 is equal to the distance l2 from the contact 1 to the contact 3.
[0072] In this embodiment, since the atomization component 200 includes a first atomization member 201 and a second atomization member 202, and the first atomization member 201 and the second atomization member 202 share a negative electrode, the data recording chip 10 in the data recording circuit 100 performs data interaction with the host through this negative electrode, and can simplify the circuit of the host by using the uniqueness of the negative electrode, so that regardless of whether the atomizer module is inserted correctly or reversely, the circuit structure of the host only needs to be designed corresponding to the unique negative electrode.
[0073] Refer to Figure 9 , Figure 9It is a schematic structural diagram of another embodiment of the electronic atomization device provided by this application. The electronic atomization device 1000 includes a host end 400 and an atomizer module 300. Among them, the host end 400 and the atomizer module 300 are detachable; the atomizer module 300 includes a data recording circuit 100 provided in any of the above embodiments.
[0074] Refer to Figure 10 , Figure 10 It is a schematic structural diagram of an embodiment of the host end provided by this application. The host end 400 includes a controller 401 and a display module 402. The display module 402 is used to display the data obtained by the controller 401 from the data recording circuit 100.
[0075] In some embodiments, the host end 400 further includes a power supply (not shown) and a housing (not shown), etc. The power supply and the controller 401 are arranged inside the housing, and the display module 402 is arranged outside the housing. The display module 402 is used to display the data obtained by the controller from the data recording circuit 100.
[0076] Refer to Figure 11 , Figure 11 It is a schematic structural diagram of another embodiment of the host end provided by this application. The host end 400 includes a controller 401, a display module 402 and a selection circuit 403. The selection circuit 403 is used to couple the negative electrode of the above-mentioned atomization component 200, and select the corresponding pin of the controller 401 to communicate with the negative electrode of the atomization component 200, so as to realize the atomization function of the atomization component 200, the data reading function of the data recording chip 10 and the data writing function respectively.
[0077] Combined with Figure 12 for illustration:
[0078] The controller 401 has a first pin 1, a second pin 2 and a third pin 3. The selection circuit 403 selects the first pin 1 of the controller 401 to communicate with the negative electrode of the atomization component 200 to realize the atomization function of the atomization component 200.
[0079] The selection circuit 403 selects the second pin 2 of the controller 401 to communicate with the negative electrode of the atomization component 200 to realize the data reading function of the data recording chip 10.
[0080] The selection circuit 403 selects the third pin 3 of the controller 401 to communicate with the negative electrode of the atomization component 200 to realize the data writing function of the data recording chip 10.
[0081] In an application scenario, the above data recording chip 10 can be used to record the remaining amount of the atomization matrix and the number of uses of the atomizer module 300. After the atomizer module 300 is electrically connected to the host 400, the data recording chip 10 transmits information to the host 400, and the data is displayed through the display module 402 of the host 400. In some embodiments, the data recording chip 10 can adopt an encrypted IC.
[0082] Furthermore, the data recording chip 10 can record the usage of its atomizer module 300, and the data is displayed through the display module 402 of the host 400, so that the user can know the detailed information of the atomizer module 300 and realize the replacement of the atomizer module 300 at any time.
[0083] Furthermore, the data recording chip 10 and the host 400 can communicate by using the heating pin wires (i.e., the positive wire and the negative wire) of the atomization component 200 of the atomizer module 300. Under normal circumstances, the pin wires are electrically connected to the host 400 to receive the voltage provided by the host 400, and there is no need to set up a separate electrode / communication wire for the data recording chip 10, which simplifies the circuit.
[0084] Furthermore, the electronic atomization device can also perform plug-in and unplug detection of the atomizer module 300 and display the locked / unlocked state on the display module 402. For example, when the atomizer module 300 is pulled out, it is not displayed.
[0085] Furthermore, when the atomizer module 300 is installed on the host, the data recording chip 10 therein is communicatively connected to the host 400 to transmit the information about the remaining atomization matrix of the atomizer module 300 stored therein, and the host 400 can update the information of the atomization matrix in the display module 402.
[0086] Furthermore, since the atomizer module 300 and the host 400 are detachable, if there is no data recording chip 10 in the newly replaced atomizer module. During the screen wake-up period of the host 400, the area for displaying the atomization matrix in the display module 402 will be displayed in the default format. For example, during the screen wake-up period, this area is displayed by flashing on and off, or flashing back and forth. When the new atomizer module works, the display module 402 can display that the atomization matrix is at 100%.
[0087] In some embodiments, the atomization component 200 in the atomizer module 300 is a dual-firing heating atomization part, that is, there are a total of three heating wire pins, and two heating wires share one pin as the negative electrode. The contact of the negative electrode is located in the middle of the two positive electrodes, so that the atomizer module 300 can be connected to the host 400 whether it is inserted correctly or reversely, and the heating and atomization of a single atomization part can be realized respectively.
[0088] In summary, for the data recording circuit 100, the atomizer module, and the electronic atomization device of the present application, the data input / output pin RSD of the data recording circuit 100 is coupled to the first end of the atomization component 200 in the atomizer module, and the data input / output pin RSD of the data recording chip 10 and the host end of the atomization device perform data interaction through the negative electrode of the atomization component 200, realizing the function multiplexing of the negative electrode of the atomization component 200. In this way, there is no need to additionally set corresponding electrodes for the data recording chip 10 on the host end and the atomizer module, simplifying the circuit and saving circuit costs. Further, the first path end of the switch circuit 20 is coupled to the first end of the atomization component 200, the lead-out wire of the second path end of the switch circuit 20 serves as the positive electrode of the atomization component 200, and the lead-out wire of the control end of the switch circuit 20 serves as the negative electrode of the atomization component 200. By using the on-off characteristic of the switch circuit 20, reasonable on-off is performed on the positive electrode side by the negative electrode to ensure the quality of data interaction between the data recording chip 10 and the host end.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, is similarly included in the patent protection scope of the present application.
