[0098] One end of the two groups of second conductive terminals 132 is received in the housing 131, and the other end passes through the housing 131 and is received outside. When the housing 131 is installed on the body 10, one end of the two groups of second conductive terminals 132 received in the housing 131 is located in the air inlet section 161 and is electrically connected to electronic components (not shown in the figure) inside the body 10. The electronic components include the power supply 19 of the power supply device 99. In this embodiment, the power supply 19 is provided on one side of the bottom plate 113 away from the first installation space 101. One end of the two groups of conductive terminals 132 received outside is respectively received in the first installation space 101 and the second installation space 102. When the first cartridge 98 is installed in the first installation space 101 and the second cartridge 97 is installed in the second installation space 102, the cartridge conductive terminal 222 establishes an electrical connection with the second conductive terminal 132.

[0099] In the above embodiment, since one end of the second conductive terminal is located in the air inlet section, when the air flow enters from the air inlet and flows through the air inlet section, the air flow can effectively dissipate heat from the second conductive terminal, preventing the temperature of the second conductive terminal from being too high during operation, and the generated heat is conducted outward through the body, which is likely to scald the user when holding the body.

[0100] In some feasible embodiments, the body 10 includes two groups of first conductive terminals (not shown in the figure). One ends of the two groups of first conductive terminals are electrically connected to the electronic components disposed inside the body 10; the other ends of the two groups of first conductive terminals respectively pass through the first mounting vacancy 101 and the second mounting vacancy 102 towards the cavity wall of the insertion port, so as to extend into the first mounting vacancy 101 and the second mounting vacancy 102 respectively. In this embodiment, the ends of the two groups of first conductive terminals connected to the electronic components are located in the air intake section 161. When the first cartridge 98 is installed in the first mounting vacancy 101 and the second cartridge 97 is installed in the second mounting vacancy 102, the cartridge conductive terminal 222 establishes an electrical connection with the first conductive terminal 17.

[0101] The side wall of the cartridge housing 22 is provided with a cartridge conductive terminal 222. In this embodiment, the cartridge housing 22 is provided with two cartridge conductive terminals 222, and the two cartridge conductive terminals 222 are arranged side by side at intervals on the side wall of the cartridge housing 22 facing the insertion plate 117. A heating component 411 and a conductive lead (not shown in the figure) are provided inside the core body 41. In this embodiment, the heating component 411 is integrally in the shape of a hollow cylinder, and the heating component 411 encloses to form a first atomization airway 980. One end of the conductive lead is electrically connected to the heating component 411, and the other end extends out from the cartridge air inlet 203 along the air inlet pipe 43 and extends to be electrically connected to the cartridge conductive terminal 222.

[0102] Specifically, the main body 20 is provided with a wire groove connecting the cartridge air inlet 203 and the cartridge conductive terminal 222. The conductive lead extending out from the cartridge air inlet 203 is arranged along the wire groove. In this embodiment, the end of the air inlet pipe 43 inserted into the cartridge air inlet 203, the corresponding part of the sealing seat 50, and the corresponding part of the fastening rib 212 are all provided with avoidance notches 4350 for the conductive lead to pass through. The avoidance notches 4350 are respectively arranged on the side of the air inlet pipe 43, the sealing seat 50, and the fastening rib 212 close to the cartridge conductive terminal 222. A wire groove 512 is opened on the surface of the extension part 51 facing the base 21 corresponding to the avoidance notch 4350, and a wire passing hole 215 is opened on the side wall of the base 21 corresponding to the wire groove 512. The cartridge housing 22 is provided with an auxiliary wire groove 223 communicating with the cartridge conductive terminal 222 corresponding to the wire passing hole 215. The end of the conductive lead far from the heating component 411 sequentially passes through the avoidance notches 4350 provided in the air inlet pipe 43 and the sealing seat 50, is arranged along the wire groove 512, sequentially extends out from the avoidance notch 4350 of the fastening rib 212 and the wire passing hole 215 to the outside of the cartridge housing 22, and is arranged along the auxiliary wire groove 223 until it is electrically connected to the cartridge conductive terminal 222.

[0103] The base 21 is further provided with positioning convex ribs 216, and the extension part 51 is correspondingly provided with positioning grooves 513. In this embodiment, the positioning convex ribs 216 are symmetrically arranged on the side of the base 21 facing the sealing seat 50. When the sealing seat 50 is installed on the base 21, the positioning convex ribs 216 are inserted into the positioning grooves 513, so that the two ends of the wire passing groove 512 respectively correspond to avoid the notch 4350 and the wire passing hole 215.

[0104] In this embodiment, a liquid storage cavity 200 for the first cartridge 98 is formed between the inner wall of the main body 20 and the outer wall of the core body 41. The liquid storage cavity 200 is used to store e-liquid. Among them, the core body 41 is provided with permeation holes 410, and the e-liquid stored in the liquid storage cavity 200 enters the core body 41 through the permeation holes 410 and is adsorbed by the heating component 411. When the first cartridge 98 is installed in the first installation space 101 and the second cartridge 97 is installed in the second installation space 102, the cartridge conductive terminal 222 is electrically connected to the first conductive terminal 17. When the power supply 19 supplies power to the heating component 411 through the conductive lead, the temperature of the heating component 411 rises and heats the e-liquid adsorbed by the heating component 411 to form an aerosol. The aerosol is discharged from the air outlet 202 under the drive of the external gas.

[0105] In this embodiment, the main body 20 is made of a light-transmitting material, and the user can observe whether the e-liquid stored in the first cartridge 98 and the second cartridge 97 is used up through the first notch 1011, the second notch 1021, or the first insertion port 1010 and the second insertion port 1020, so that the user can intuitively understand the usage conditions of the first cartridge 98 and the second cartridge 97. Among them, the light-transmitting material includes but is not limited to glass, acrylic, etc.

[0106] The carrier plate 112 is provided with air holes 1120 communicating the first installation space 101 and the second installation space 102. In this embodiment, the position of the air holes 1120 on the carrier plate 112 corresponds to the air inlet 14 and the suction port 15. The main body 10 is further provided with a gas guiding member 18 (as shown in Figure 10 the figure) at the air holes 1120. The two ends of the gas guiding member 18 are respectively communicated with the air outlet gas path of the first cartridge 98 and the air inlet gas path of the second cartridge 97, so that the air flow flowing out of the first cartridge 98 enters the second cartridge 97 only through the gas guiding member 18. That is to say, the two ends of the gas guiding member 18 are respectively connected to the air outlet pipe 42 of the first cartridge 98 and the air inlet pipe 43 of the second cartridge 97, so that the air holes 1120 are respectively communicated with the air outlet 202 of the first cartridge 98 and the air inlet 203 of the second cartridge 97.

[0107] On the inner walls of the first installation space 101 and the second installation space 102 of the main body 10 facing the insertion port, first magnetic members 191 are provided. The first cartridge 98 and the second cartridge 97 are respectively provided with corresponding second magnetic members 910. In this embodiment, the first magnetic member 191 is disposed in the housing 131 of the conductive assembly 13, and the second magnetic member 910 is disposed on the side of the first cartridge 98 and the second cartridge 97 facing the insertion plate 117. When the first cartridge 98 and the second cartridge 97 are inserted into the first installation space 101 and the second installation space 102 along the corresponding insertion ports, the first magnetic member 191 and the second magnetic member 910 are magnetically connected to fix the first cartridge 98 and the second cartridge 97 to the main body 10.

[0108] On the bottom walls enclosing the first installation space 101 and the second installation space 102 of the main body 10, third magnetic members (not shown in the figure) are provided. The first cartridge 98 and the second cartridge 97 are respectively provided with corresponding fourth magnetic members (not shown in the figure). The third magnetic members are respectively disposed at one end of the bottom wall of the first installation space 101 away from the first insertion port 1010 and one end of the bottom wall of the second installation space 102 away from the second insertion port 1020. The fourth magnetic members are respectively disposed at the bottom walls of one end of the first cartridge 98 preferentially inserted into the first installation space 101 and one end of the second cartridge 97 preferentially inserted into the second installation space 102. When the first cartridge 98 and the second cartridge 97 are inserted into the corresponding first installation space 101 and second installation space 102, at least a part of the third magnetic member and the fourth magnetic member are disposed opposite to each other. In this embodiment, a part of the third magnetic member and the fourth magnetic member are disposed opposite to each other. That is to say, the positions of the third magnetic members respectively disposed on the bottom walls of the first installation space 101 and the second installation space 102 are closer to the insertion plate 117 than the positions of the fourth magnetic members respectively disposed on the bottom walls of the first cartridge 98 and the second cartridge 97. In some feasible embodiments, the third magnetic member and the fourth magnetic member are completely disposed opposite to each other.

[0109] In the above embodiment, a part of the third magnetic member and the fourth magnetic member are disposed opposite to each other, so that the third magnetic member has a magnetic traction force towards the insertion plate on the fourth magnetic member. Under the action of the magnetic traction force, while the first cartridge and the second cartridge are respectively installed in the first installation space and the second installation space, the cartridges are not easily slid out of the installation space under the influence of external force, and the cartridges can also establish a more stable electrical connection with the main body.

[0110] The electronic components inside the main body 10 further include the main control board 70 of the power supply device 99. In this embodiment, the main control board 70 is disposed on the side of the conductive component 13 away from the suction port 15. The power supply device 99 further includes an adjustment button structure 60, and the adjustment button structure 60 is electrically connected to the main control board 70. The housing 12 is provided with a chute 120 at a position corresponding to the adjustment button structure 60. One end of the adjustment button structure 60 passes through the chute 120 and is connected to the main control board 70, and the other end of the adjustment button structure 60 is exposed to the outside from the chute 120 to form a control part 61 for the user to operate. In this embodiment, the end of the control part 61 away from the main control board 70 is convexly provided with anti-slip ridges to enhance the friction force and facilitate the user to operate. In some feasible embodiments, irregular patterns can be provided on the end face of the control part 61 away from the main control board 70, or other materials capable of increasing the friction force can be provided at the end of the control part 61 away from the main control board 70, which will not be elaborated here. When the user operates the control part 61, the control part 61 slides along the chute 120 and triggers the main control board 70 to generate different electrical signals. In this embodiment, when the main control board 70 generates a first electrical signal, the first cartridge 98 works; when the main control board 70 generates a second electrical signal, the second cartridge 97 works; when the main control board 70 generates a third electrical signal, the first cartridge 98 and the second cartridge 97 work simultaneously.

[0111] In the above embodiment, since the power supply device can install two cartridges, the liquid storage cavities in the two cartridges can store two different flavors of e-liquid respectively. Then when only the first cartridge works, a kind of flavored smoke is generated; when only the second cartridge works, another flavored smoke is generated. And the first atomization airway inside the first cartridge and the second atomization airway inside the second cartridge are both communicated with the air flow channel. The outside air enters the air flow channel from the air inlet and passes through the first atomization airway and the second atomization airway in sequence and then is discharged from the suction port. When the two cartridges work simultaneously, a mixed flavored smoke will be generated, thus meeting the user's demand for multi-flavored e-cigarettes. The user can trigger the main control to generate different electrical signals through the adjustment button structure according to personal needs, so as to control the power supply device to supply power to the first cartridge or the second cartridge alone, or supply power to the first cartridge and the second cartridge simultaneously.

[0112] The main body 10 is also provided with two groups of indicator lights (not shown in the figure) electrically connected to the electronic components inside the main body 10. Specifically, the two groups of indicator lights are electrically connected to the main control board 70, and the two groups of indicator lights respectively irradiate the first installation vacancy 101 and the second installation vacancy 102 to indicate the working states of the corresponding first cartridge 98 and second cartridge 97. In this embodiment, the two groups of indicator lights are respectively arranged on one side of the insertion board 117 corresponding to the first installation vacancy 101 facing the first insertion port 1010 and on one side of the insertion board 117 corresponding to the second installation vacancy 102 facing the second insertion port 1020. When the first cartridge 98 works, the indicator light corresponding to the first installation vacancy 101 lights up; when the second cartridge 97 works, the indicator light corresponding to the second installation vacancy 102 lights up; when the first cartridge 98 and the second cartridge 97 work simultaneously, both groups of indicator lights light up.

[0113] In some feasible embodiments, the two groups of indicator lights can be installed at positions convenient for users to view, such as on the side wall of the housing 12, which is not limited herein.

[0114] In the above embodiments, in different working modes of the power supply device, the two groups of indicator lights will produce different display states, and users can respectively understand the working conditions of the first cartridge and the second cartridge according to the display states of the two groups of indicator lights.

[0115] The main body 10 further includes an air regulating structure 80, and the air regulating structure 80 is arranged at the air inlet 14. In this embodiment, the air regulating structure 80 includes a rotating disk 81 and a damping member 82. Among them, the rotating disk 81 is installed on the damping member 82 and can rotate relative to the damping member 82, and the damping member 82 is fixed to the housing 12. The rotating disk 81 is provided with an air inlet groove 811 and an auxiliary air hole 812, and the damping member 82 is provided with an air passing groove 820 communicated with the air inlet 14. In this embodiment, the air passing groove 820 and the air inlet groove 811 are arc-shaped. Among them, the size of the air inlet groove 811 is larger than the size of the air passing groove 820. During the process of rotating the rotating disk 81, the air inlet groove 811 is communicated with the air passing groove 820, or the auxiliary air hole 812 is communicated with the air passing groove 820. Users can rotate the rotating disk 81 to change the size of the conduction area between the air inlet groove 811 and the air passing groove 820, so as to adjust the size of the external gas entering the air inlet 14. The auxiliary air hole 812 is opened on the side opposite to the air inlet groove 811 to prevent the rotating disk 81 from completely blocking the air passing groove 820. In some feasible embodiments, the air regulating structure 80 can be other components with air regulating functions, which is not limited herein.

[0116] In the above embodiments, the power supply device is provided with an air regulating structure for adjusting the size of the external gas entering the main body, and users can adjust it according to their own needs. At the same time, the setting of the auxiliary air hole can prevent the external gas from not flowing in from the air inlet when the power supply device works, and the phenomenon of dry burning of the first cartridge or the second cartridge occurs.
