The boss 5 is arranged on the battery box shell 21. The position of the boss 5 is aligned with the position of the spring pin 4. When the atomizer 1 is used independently, the spring pin 4 presses the spring piece 3 to put the switch in the on state. After the battery box 2 is docked with the atomizer 1, the boss 5 presses the spring pin 4 to make the spring pin 4 separate from the spring piece 3, the switch is in the off state, and the battery box PCB board 22 is docked with the atomizer PCB board 12 through the ejector pin 9.

[0026] A first contact 13 and a second contact 14 are provided on the atomizer PCB board 12. One end of the spring sheet 3 is connected to the first contact 13, and the other end of the spring sheet 3 is located at the second contact 14.

The process of switching the circuit by changing the position of the spring needle 4 is achieved by switching the relative positions of the contact piece protrusion 43, the avoidance groove 42 and the raised portion 31 of the spring piece 3. When the battery box 2 is separated from the atomizer 1, the contact piece protrusion 43 contacts the raised portion 31 of the spring piece 3 to press the spring piece 3 to realize the conduction of the switch. When the battery box 2 is connected to the atomizer 1, the avoidance groove 42 is located at the position of the raised portion 31 of the spring piece 3.

[0029] The atomizer PCB board 12 is provided with an atomizer interface, and the battery box PCB board 22 is provided with a battery box interface. When the battery box 2 is docked with the atomizer 1, the atomizer interface is connected with the battery box interface.

[0030] The dual-battery powered interactive control structure also includes a magnet 6, and the corresponding positions of the atomizer 1 shell and the battery box 2 shell are connected with the magnet 6, and the battery box 2 and the atomizer 1 are detachably connected through the magnet 6. A pair of magnets 6 are respectively provided at the upper and lower ends of the atomizer 1 shell and the battery box 2 shell. When docking, it is only necessary to align the position of the magnet 6 of the battery box 2 with the position of the magnet 6 on the atomizer 1, and use the suction force of the magnet 6 to fix the battery box 2 on the atomizer 1, so that the boss 5 and the spring pin 4, and the atomizer interface and the battery box interface are all docked.

[0031] The working principle of the contact point switch on the atomizer PCB board 12: The first battery BAT1 positive electrode spring 3 contacts the point A (i.e. the second contact 14, such as Figure 5 BAT1+) and the spring 3 contact point B (i.e. the first contact point 13, Figure 5 The two contact points form a switch (i.e. Figure 5When the elastic piece 3 is subjected to an external force and moves towards the inner side of the atomizer 1, the elastic piece 3 on the atomizer PCB board 12 does not receive a downward pressure and rebounds away from the contact point B of the needle 4, so that the switch SW1 is in an off state, and at this time, the first battery BAT1 is disconnected from power supply; when the movable elastic piece 3 is not subjected to an external force, it will rebound towards the outer side of the atomizer 1, that is, press the elastic piece 3 on the atomizer PCB board 12 downward, so that the contact point A of the elastic piece 3 is connected to the contact point B of the elastic piece 3, and at this time, the first battery BAT1 conducts power supply.

[0032] As Figure 7 shown, an atomizer power supply circuit is provided inside the atomizer PCB board 12.

[0033] The atomizer power supply circuit further includes a chip U2, a heating wire FH1, a heating wire FH2, a thimble interface R1+, and a thimble interface R2+. The VDD pin of the chip U2 is connected to the first contact B1+, and the OUT pin of the chip U2 is respectively connected to the thimble interface R1+ and one end of the heating wire FH1. The other end of the heating wire FH1 is respectively connected to one end of the heating wire FH2 and grounded, and the other end of the heating wire FH2 is connected to the thimble interface R2+.

[0034] As Figure 8 shown, a battery box power supply circuit is provided inside the battery box PCB board 22. The battery box power supply circuit includes a chip M1, a second battery BAT2, MOS transistors Q1, Q2, a thimble interface F1+, a thimble interface F2+, a thimble interface FH2-, and resistors R9, R10, R13, R14, R15. The positive electrode of the second battery BAT2 is respectively connected to the drain of the MOS transistor Q1, the drain of the MOS transistor Q2, one end of the resistor R9, and one end of the resistor R13. The gate of the MOS transistor Q1 is respectively connected to the other end of the resistor R9 and one end of the resistor R12, and the other end of the resistor R12 is connected to the 15th pin of the chip M1. The gate of the MOS transistor Q2 is respectively connected to the other end of the resistor R13 and one end of the resistor R15, and the other end of the resistor R15 is connected to the 14th pin of the chip M1. The source of the MOS transistor Q1 is respectively connected to one end of the resistor R10 and the thimble interface F1+, and the other end of the resistor R10 is connected to the 13th pin of the chip M1. The source of the MOS transistor Q2 is respectively connected to one end of the resistor R14 and the thimble interface F2+, and the other end of the resistor R14 is connected to the 16th pin of the chip M1. The thimble interface FH2- is grounded.

[0035] In the present utility model, the first battery BAT1 inside the atomizer 1 and the second battery BAT2 in the battery box 2 are separated and powered separately. When the second battery BAT2 is connected, the second battery BAT2 serves as the power source. When the second battery BAT2 is not connected, the first battery BAT1 supplies power, enabling free switching between the two groups of batteries for power supply, which can greatly improve the battery life and thus meet outdoor use requirements to satisfy large-capacity atomization needs.

[0036] The main working modes of the present utility model are as follows:

[0037] (1) Working mode of the first battery BAT1: A shrapnel 3 is designed on the atomizer PCB board 12. One end of the shrapnel 3 is welded to the atomizer positive contact B1+ on the atomizer PCB board 12, and the other end can elastically move up and down. In the initial state, the shrapnel 3 presses on the pad of the atomizer PCB board 12 and the positive electrode of the second contact BAT1+. When the second battery BAT2 is not connected, the head of the ejector pin 4 presses the shrapnel 3, causing the shrapnel 3 to press on the BAT1+ positive electrode of the atomizer PCB board 12. At this time, the first battery BAT1 serves as the working power source for the entire atomizer 1 to provide electrical energy. At the same time, R1+ and R2+ are respectively connected to the heating wires FH1 and FH2 through the circuits on the atomizer PCB board. The first battery BAT1 supplies power to the heating wires through the atomizer power supply circuit.

[0038] (2) Working mode of the second battery BAT2: When the second battery BAT2 is connected, under the influence of the suction force of the magnet 6, the ejector pin 4 is extruded inward by the external force of the convex column 5. At this time, the shrapnel 3 on the second contact BAT1+ of the atomizer PCB board 12 bounces upward, changing the position of the shrapnel 3. The switch SW1 of the first battery BAT1 changes from the conducting state to the off state, so that the first battery BAT1 cannot supply power to the atomizer 1. At this time, the second battery BAT2 and the heating wires of the atomizer 1 are powered through the ejector pin 9, and the working state is controlled by the internal control of the second battery BAT2. The convex column 5 is preferably a plastic column and is non-conductive. When the battery box 2 attracts the atomizer 1, the ejector pin 41 is pushed by the force of the convex column, keeping the ejector pin 43 in the pushed state and releasing the shrapnel 3. The conduction of the second battery BAT2 to the heating wires in the atomizer 1 is achieved through the docking of the ejector pin 9 on the battery box 2 and the ejector pin 9 on the atomizer 1.

[0039] (3) During the operation of the atomizer 1, as long as the second battery BAT2 is connected, the ejector pin 4 is always under force, and the switch SW1 of the first battery BAT1 is always in the off state, that is, the second battery BAT2 always supplies power. When the second battery BAT2 is removed, the first battery BAT1 returns to the contact state, and at this time, the first battery BAT1 supplies power.

[0040] After the battery box 2 is docked with the atomizer 1, that is, when BAT2 is connected, the thimble interface F1+ is in contact conduction with the thimble interface R1+, the thimble interface F2+ is in contact conduction with the thimble interface R2+, and the thimble interface FH2- is in contact conduction with the thimble interface FH1-. At this time, the heating wires FH1 and FH2 are powered by the thimble interfaces F1+, F2+, and FH2-. The R1+ and R2+ ends of the heating wires are connected to the second battery BAT2, and the working state of the heating wires is controlled by the circuit module of BAT2. The three thimbles 9 provided on the atomizer PCB board 12 are the thimble interface R1+, the thimble interface FH1-, and the thimble interface R2+ respectively. The three thimbles 9 provided on the battery box PCB board 22 are the thimble interface F1+, the thimble interface FH2-, and the thimble interface F2+ respectively.

[0041] When the atomizer 1 of the present utility model is working, it can achieve internal power supply. When an external battery box 2 is connected, it is powered externally. When the external battery box 2 is not connected, it is powered by the internal battery of the disposable atomizer 1. Through different battery power supply working methods, it can meet the user's battery life ability and can also customize the capacity of a certain battery box 2 to meet the battery life needs of different people.

[0042] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
