[0027] The electronic atomization device includes an atomizer and a battery assembly. For disposable electronic atomization devices, the atomizer and the battery assembly are assembled as one when they leave the factory. During transportation and storage, the atomizer consumes the power of the battery assembly and the consumption of the battery assembly itself, resulting in a reduction in the number of times the disposable electronic atomization device is used by the user; or due to interference from the external environment during transportation and storage, the electronic atomization device self-starts, causing the battery assembly to power the atomizer, and the atomizer atomizes the substrate to be atomized in the electronic atomization device. At this time, due to the relatively closed environment during transportation or storage, the heating element 46 of the atomizer cannot dissipate heat in time, causing the internal temperature of the atomizer to be too high, which may burn the outer shell 40 of the electronic atomization device, causing the internal temperature of the atomizer to be too high and reducing safety.

[0028] In response to the defects of the above-mentioned disposable electronic atomization device, the present application provides an electronic atomization device, which can cut off the electrical connection between the atomizer and the battery assembly during transportation and storage, which can not only reduce the loss of the battery assembly and increase the number of times the disposable electronic atomization device is used; but also reduce the self-starting of the disposable electronic atomization device and improve the safety of transportation and use.

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] See Figure 1 , Figure 1 This is a functional module diagram of the first embodiment of the present invention. The electronic atomization device includes a drive control circuit 10 and a power supply circuit 20. The drive control circuit 10 is connected to the heating element 46 of the electronic atomization device to drive the heating element 46 of the electronic atomization device. The power supply circuit 20 is connected between the drive control circuit 10 and the power supply device 30 so that the power supply device 30 supplies power to the drive control circuit 10 through the power supply circuit 20.

[0031] Among them, the power supply circuit 20 includes a control component, which puts the power supply circuit 20 into a first state or a second state according to external excitation. When the power supply circuit 20 is in the first state, the power supply circuit 20 closes the path between the power supply device 30 and the drive control circuit 10 and does not supply power to the drive control circuit 10; when the power supply circuit 20 is in the second state, the power supply circuit 20 opens the path between the power supply device 30 and the drive control circuit 10 to supply power to the drive control circuit 10.

[0032] It can be understood that the power supply circuit 20 connects the power supply device 30 and the drive control circuit 10, and the control component of the power supply circuit 20 is stimulated by the outside, so that the power supply circuit 20 is in the first state or the second state. In the first state, the power supply circuit 20 closes the connection path between the power supply device 30 and the drive control circuit 10, so that the power supply device 30 cannot supply power to the drive control circuit 10, and further, the drive control circuit 10 cannot drive the heating element 46 to work. In this way, during transportation and storage, the drive control circuit 10 will not self-start when affected by the external environment, and thus the electronic atomization device will not cause unnecessary safety hazards due to excessive internal temperature, thereby improving transportation safety. In addition, because the power supply device 30 does not supply power to the drive control circuit 10, only the power supply device 30 itself is lost, which can effectively reduce the power consumption of the power supply device 30 and increase the number of times the disposable electronic atomization device is used.

[0033] In the second state, the power supply circuit 20 connects the path between the power supply device 30 and the drive control circuit 10, and the power supply device 30 supplies power to the drive control circuit 10. At this time, the drive control circuit 10 can drive the heating element 46. In this state, the electronic atomization device can receive the user's working instructions, so that the drive control circuit 10 drives the heating element 46 to atomize the matrix to be atomized in the electronic atomization device.

[0034] In this embodiment, the external excitation can be performed when the electronic atomizer is shipped from the factory, or by a user after the electronic atomizer is released to the market. This external excitation simply changes the state of the power supply circuit 20, thereby opening or closing the path between the drive control circuit 10 and the power supply device 30, and does not affect the operating state of the drive control circuit 10.

[0035] See also Figure 2 , Figure 2 FIG1 is a schematic diagram of the circuit structure of the first embodiment of the present invention. The electronic atomization device includes a power supply circuit 20 and a drive control circuit 10.

[0036] Among them, the power supply circuit 20 includes a control component, which includes a metal spring 21 and an insulating sheet 22. The metal spring 21 is used to connect to the metal contact 27 of the power supply circuit 20, and the insulating sheet 22 is pluggable through the outer shell of the electronic atomization device and is arranged between the metal spring 21 and the metal contact 27 of the power supply circuit 20, so that the power supply circuit 20 is in the first state or the second state.

[0037] When the insulating sheet 22 is inserted between the metal spring sheet 21 and the metal contact 27, the metal spring sheet 21 is in non-contact with the metal contact 27 of the power supply circuit 20, and the power supply circuit 20 is in the first state; when the insulating sheet 22 is pulled out, the metal spring sheet 21 contacts the metal contact 27 of the power supply circuit 20, and the power supply circuit 20 is in the second state.

[0038] Furthermore, the power supply circuit 20 also includes a switch 23, which is connected between the power supply device 30 and the drive control circuit 10, and the control end of the switch 23 is connected to the metal spring 21; wherein, when the insulating sheet 22 is inserted between the metal spring 21 and the metal contact 27, the switch 23 closes the path between the power supply device 30 and the drive control circuit 10, so that the power supply circuit 20 is in the first state; when the insulating sheet 22 is pulled out, the switch 23 opens the path between the power supply device 30 and the drive control circuit 10, so that the power supply circuit 20 is in the second state.

[0039] Specifically, the switch 23 includes a first path end, a second path end, and a control end. The first path end of the switch 23 is connected to the drive control circuit 10, the second path end of the switch 23 is connected to the power supply device 30, and the control end of the switch 23 is connected to one end of the metal dome 21. The other end of the metal dome 21 is used to connect to the metal contact 27 of the power supply circuit 20. In this embodiment, the metal contact 27 can also be a metal dome.

[0040] When the insulating sheet 22 is inserted between the metal spring 21 and the metal contact 27, the metal spring 21 is separated from the metal contact 27, and the switch 23 closes the path between the power supply device 30 and the drive control circuit 10, so that the power supply circuit 20 is in the first state, reducing the power loss of the power supply device 30 and the self-starting of the drive control circuit 10. In actual production use, the quiescent current of the electronic atomization device in this embodiment is 3 to 15uA. When the power supply circuit 20 is in the first state, the power supply device 30 will reduce the self-consumption by 3 to 15uA. If calculated on an annual basis, the loss will be reduced by 26.28 to 131.4mA / h.

[0041] When the insulating sheet 22 is pulled out, the metal spring 21 contacts the metal contact 27, and the switch 23 connects the path between the power supply device 30 and the drive control circuit 10, so that the power supply circuit 20 is in the second state. In this state, the electronic atomization device can receive the working instructions of the terminal user, so that the drive control circuit 10 drives the heating element 46 to atomize the substrate to be atomized in the electronic atomization device.

[0042] Furthermore, the power supply circuit 20 also includes a pressure-up resistor R, which includes a first end and a second end. The first end of the pressure-up resistor R is connected to the second path end of the switch 23, and the second end of the pressure-up resistor R is connected to the control end of the switch 23. The pressure-up resistor R can enable the switch 23 to maintain a certain logic high level when the power supply circuit 20 is in the first state. When the insulating sheet 22 is pulled out and the metal spring 21 contacts the metal contact 27, the switch 23 can smoothly conduct the path between the power supply device 30 and the drive control circuit 10.

[0043] Furthermore, in one embodiment, Figure 3 As shown, in order to reduce production costs and reduce the size of the electronic atomization device, the power supply circuit 20 only includes a metal shrapnel 21 and an insulating sheet 22, wherein the metal shrapnel 21 is connected to the positive electrode of the power supply device 30. When the insulating sheet 22 passes through the housing of the electronic atomization device and is inserted between the metal shrapnel 21 and the metal contact 27 of the power supply circuit 20, the power supply circuit 20 is in a first state, and the power supply circuit 20 closes the path between the power supply device 30 and the drive control circuit 10; when the insulating sheet 22 is pulled out, the metal shrapnel 21 contacts the metal contact 27 of the power supply circuit 20, and the power supply circuit 20 is in a second state, and the power supply circuit 20 opens the path between the power supply device 30 and the drive control circuit 10.

[0044] In another embodiment, Figure 4 As shown, Figure 3 The power supply circuit 20 shown is different in that the metal spring 21 is connected to the negative electrode of the power supply device 30 .

[0045] The drive control circuit 10 includes a control chip 11, a heating control unit 12, an atomization signal detection unit 13, and a status indication unit 14. The control chip 11 is connected to the power supply circuit 20, the heating control unit 12, the atomization signal detection unit 13, and the status indication unit 14, and the heating control unit 12 is connected to the heating element 46 of the electronic atomization device.

[0046] Specifically, when the power supply circuit 20 is in the second state, the atomization signal detection unit 13 detects the externally input atomization signal, so that the control chip 11 controls the heating control unit 12 to drive the heating element 46 of the electronic atomization device. At this time, when the heating control unit 12 drives the heating element 46 of the electronic atomization device, the status indicator unit 14 is used to indicate the operating status of the heating element 46. In this embodiment, the atomization signal detection unit 13 can be a switch component that starts the control chip 11, and the status indicator unit 14 can include an LED light 141, which indicates the operating status of the heating unit, such as normal working state, low voltage state, etc.

[0047] See also Figure 5 , Figure 5 FIG. 1 is a schematic diagram of the circuit structure of the second embodiment of the present invention. Figure 2 The difference between the circuit structure schematic diagram shown is that the power supply circuit 20 includes a control component, and the control component includes a button 24, wherein when the button 24 is in a first excitation state under a first external excitation, the power supply circuit 20 is in a first state to close the path between the power supply device 30 and the drive control circuit 10; when the button 24 is in a second excitation state under a second external excitation, the power supply circuit 20 is in a second state to open the path between the power supply device 30 and the drive control circuit 10.

[0048] Furthermore, the power supply circuit 20 also includes a first switch 25, which includes a first path end, a second path end and a control end. The first path end of the first switch 25 is connected to the drive control circuit 10, the second path end of the first switch 25 is connected to the power supply device 30, and the control end of the first switch 25 is connected to the button 24; wherein, when the button 24 is in a first excitation state by a first external excitation, the first switch 25 is closed to close the path between the power supply device 30 and the drive control circuit 10; when the button 24 is in a second excitation state by a second external excitation, the first switch 25 is turned on to open the path between the power supply device 30 and the drive control circuit 10.

[0049] Furthermore, the button 24 is an excited and self-recovering button 24, and the power supply circuit 20 also includes a power supply maintenance control circuit 26, which is connected to the control end of the first switch 25; wherein, when the button 24 is in the second excited state by the second external excitation to turn on the first switch 25, the power supply maintenance control circuit 26 is turned on to continue to maintain the first switch 25 after the button 24 is restored; when the button 24 is in the first excited state by the first external excitation, the power supply maintenance control circuit 26 is disconnected to end maintaining the first switch 25.

[0050] Furthermore, the drive control circuit 10 includes a control chip 11, which includes a first port n1, a second port n2 and a third port n3. The first port n1 of the control chip 11 is connected to the power supply device 30 through the first switch 25. The second port n2 of the control chip 11 is connected to the control end of the first switch 25 and the circuit where the button 24 is located to detect the status of the button 24. The third port n3 of the control chip 11 is connected to the power supply maintenance control circuit 26. Among them, when the control chip 11 detects through the second port n2 that the button 24 is in the second excitation state due to the second external excitation, causing the first switch 25 to be turned on, the control chip 11 obtains power from the power supply device 30 through the turned-on first switch 25 to be in a working state, and sends a maintenance control instruction to the power maintenance control circuit 26 through the third port n3 to turn on the power maintenance control circuit 26, so that the button 24 continues to maintain the first switch 25 after recovery; when the control chip 11 detects through the second port n2 that the button 24 is in the first excitation state due to the first external excitation, the control chip 11 sends a disconnection instruction to the power maintenance control circuit 26 through the third port n3 to disconnect the power maintenance control circuit 26, thereby ending the maintenance of the first switch 25.

[0051] Furthermore, the power supply maintenance control circuit 26 includes a second switch 261, wherein the second switch 261 includes a first path end, a second path end, and a control end. The first path end of the second switch 261 is connected to the control end of the first switch 25, the control end of the second switch 261 is connected to the third port n3 of the control chip 11, and the second path end of the second switch 261 is grounded. When the second switch 261 receives an instruction to turn on, the power supply maintenance control circuit 26 is turned on to continue to keep the first switch 25 turned on after the button 24 is restored; when the second switch 261 receives an instruction to turn off, the power supply maintenance control circuit 26 is turned off to stop keeping the first switch 25 turned on.

[0052] Furthermore, the first switch 25 is a P-type transistor, and the second switch 261 is an N-type transistor.

[0053] In this embodiment, the above content can be specifically understood as follows: the first external excitation is to touch the button 24 for at least 2 seconds before leaving the factory, placing the button 24 in the first excitation state. When the control chip 11 detects that the button 24 is in the first excitation state through the second port n2, the third port n3 of the control chip 11 outputs a low level to the second switch 261, which closes, disconnecting the power supply maintenance control circuit 26 and ending the maintenance of the first switch 25. At this time, the control terminal of the first switch 25 is the supply voltage of the power supply device 30, that is, the first switch 25 is disconnected, and the power supply circuit 20 is in the first working state, thereby closing the path between the drive control circuit 10 and the power supply device 30. When the power supply circuit 20 is in the first state, it facilitates the transportation and storage of the electronic atomization device. In actual production use, the quiescent current of the electronic atomization device in this embodiment is 3 to 15 uA. When the power supply circuit 20 is in the first state, the power supply device 30 will reduce its self-consumption by 3 to 15 uA, which is a reduction of 26.28 to 131.4 mA / h on an annual basis.

[0054] The second external excitation is to touch the button 24, so that the button 24 is in the second excitation state, the first switch 25 is turned on, and the power supply device 30 supplies power to the drive control circuit 10. At this time, the control chip 11 of the drive control circuit 10 detects that the button 24 is in the second excitation state through the second port n2, and the third port n3 of the control chip 11 outputs a high level to the second switch 261. The second switch 261 is turned on to keep the power supply control circuit 26 turned on, so that the first switch 25 remains turned on after the button 24 is restored, so as to maintain the path between the drive control circuit 10 and the power supply device 30. The control chip 11 controls the first switch 25 by controlling the second switch 261, thereby facilitating the control chip 11 to control the power supply devices 30 of different voltages.

[0055] Furthermore, the power supply circuit 20 also includes a resistor R1, a resistor R3, a diode D1 and a diode D2, wherein the resistor R1 includes a first end and a second end, the resistor R3 includes a first end and a second end, the diode D1 includes a first end and a second end, and the diode D2 includes a first end and a second end.

[0056] Specifically, the first end of resistor R1 is connected to the control terminal of first switch 25, the second end of resistor R1 is connected to the first end of diode D2, and the second end of diode D2 is connected to button 24, thereby forming a circuit for the first switch 25 and button 24. The first end of resistor R3 is connected to the circuit for the first switch 25 and button 24, and the second end of resistor R3 is connected to power supply device 30. The first end of diode D1 is connected to the second port n2 of control chip 11, and the second end of diode D1 is connected to the circuit for the first switch 25 and button 24, for detecting the status of button 24. Diodes D1 and D2 are both used to prevent voltage backflow from power supply device 30 when the first switch 25 and second switch 261 are disconnected, thereby protecting the first switch 25 and second switch 261.

[0057] Furthermore, the power supply maintenance control circuit 26 also includes a resistor R2 and a resistor R4, wherein the resistor R2 includes a first end and a second end, and the resistor R4 includes a first end and a second end. The first end of the resistor R2 is connected to the third port n3 of the control chip 11, the second end of the resistor R2 is connected to the control end of the second switch 261, the first end of the resistor R4 is connected to the control end of the second switch 261, and the second end of the resistor R4 is connected to the second path end of the second switch 261.

Figure 2 、 Figure 3 or Figure 4 The heating element 46 shown is arranged in the atomization chamber 42, and the drive control circuit 10 and the power supply circuit 20 are encapsulated on the PCB board 43, wherein the status indication unit 14 of the drive control circuit 10 includes an LED lamp 141, and the LED lamp 141 is penetrated on the side wall of the shell 40, and the atomization signal detection unit 13 of the drive control circuit 10 includes a sensor device 131 provided on the shell 40; the insulating sheet 22 of the power supply circuit 20 is independent of the PCB board 43.

[0059] In one embodiment, the air inlet 44 is in fluid communication with the sensor device 131 , so that when the sensor device 131 detects the puffing action of the end user, the electronic atomization device is activated to operate normally.

[0060] Specifically, such as Figure 6 and Figure 7 As shown, the sensing device 131 includes a sensor 31, a main controller 32, a substrate 35 and a shell 36, wherein the substrate 35 has a first vent 33, and the first vent 33 is connected to the airway fluid in the electronic atomization device. The sensor 31 is located on the first surface of the substrate 35, and one end of the sensor 31 is located on one side of the first vent 33, and the other end of the sensor 31 is located on the other side of the first vent 33. The shell 36 is also located on the first surface of the substrate 35 and covers the sensor 31 and the main controller 32. In addition, the shell 36 has a second vent 34, and the second vent 34 is connected to the air inlet 44 fluid to obtain the reference air pressure P0. The main controller 32 is electrically connected to the sensor 31 through a metal wire, and the main controller 32 is electrically connected to the substrate 35 through a metal wire. In this embodiment, the substrate 35 is a circuit board.

[0061] It can be understood that, Figure 8 As shown, the power supply circuit 20 is in the first state, that is, when the insulating sheet 22 passes through the air inlet hole 44 and is inserted between the metal spring 21 and the metal contact 27 of the power supply circuit 20, the air inlet hole 44 is sealed, the second air vent 34 cannot be connected to the external fluid, and the sensing device 131 cannot work normally, thereby preventing the electronic atomization device from self-starting, thereby improving the safety of transportation and storage.

[0062] like Figure 9 As shown, the power supply circuit 20 is in the second state, that is, the insulating sheet 22 is pulled out from the air inlet 44, and when the metal spring 21 contacts the metal contact 27 of the power supply circuit 20, the air inlet 44 is connected to the external gas, that is, the second air vent 34 is connected to the external gas, and the terminal user inhales the electronic atomization device, the sensor device 131 detects the inhalation signal, and the electronic atomization device starts to work.

[0063] It can be further understood that when the end user takes a puff, if the first vent 33 connected to the airway in the electronic atomization device is at an air pressure P, and the second vent 34 connected to the external gas fluid is at a reference air pressure P0, then the sensor 31 detects the airflow change as △P=P-P0 through the first vent 33. The airflow difference △P can change the capacitance distance of the sensor 31, so that the capacitance changes. The main controller 32 outputs a first control signal according to the change in capacitance value. The control chip 11 receives the first control signal and controls the heating control unit 12 to drive the heating element 46 of the electronic atomization device. Figure 2 shown.

[0064] Furthermore, in one embodiment, the sensor device 131 is a MEMS sensor.

[0065] In another embodiment, the air inlet 44 can further be connected to the air passage fluid of the suction nozzle 41. When the insulating sheet 22 is inserted through the air inlet 44 and between the metal spring 21 and the metal contact 27 of the power supply circuit 20, the air inlet 44 is sealed, and the air passage of the suction nozzle 41 is further prevented from communicating with the external fluid. In this case, compared with the above-mentioned case where the insulating sheet 22 is inserted through the air inlet 44 to prevent the sensor device 131 from communicating with the external fluid and the power supply circuit 20 is in the first state, the self-starting of the electronic atomization device can be further prevented, thereby further improving the safety of transportation and storage.

[0066] See also Figure 10 , Figure 10 This is a schematic diagram of the structure of the second embodiment of the present invention. Figure 6 The electronic atomizer device shown here differs in that a pinhole 45 and a sensor device 131 are provided on the housing 40 of the electronic atomizer device; a drive control circuit 10 and a power supply circuit 20 are packaged on the PCB board 43. The button 24 in the power supply circuit 20 corresponds to the pinhole 45, and the second vent 34 of the sensor device 131 is in fluid communication with the outside world.

[0067] Specifically, in this embodiment, before the electronic atomization device leaves the factory, a sharp needle or other rod-shaped object is used to pass through the pinhole 45 and touch the button 24 for two seconds. The button 24 is reset, so that the power supply circuit 20 is in the first state, and the path between the power supply circuit 20 and the drive control circuit 10 is closed, so as to facilitate the transportation and storage of the electronic atomization device.

[0068] When the end user uses it, a sharp needle or other rod-shaped object is used to pass through the pinhole 45 and touch the button 24. At this time, the power supply circuit 20 is in the second state, and the sensor device 131 detects the external input atomization signal, so that the control chip 11 controls the heating control unit 12 to drive the heating element 46 of the electronic atomization device, wherein the external input atomization signal is the puff signal of the end user.

Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
