Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.

[0033] Please refer to Figures 1 to 5 The present invention provides a leak-proof dual-tank cartridge 100, comprising a tank shell 10, an atomizer core 20 disposed in the tank shell 10, and a base 30 sealing the bottom of the tank shell 10. The atomizer core 20 of this embodiment can adopt a conventional design, such as including an atomizer core bracket, oil-guiding cotton, a heating wire and other structures.

[0034] Among them, the interior of the oil tank shell 10 is provided with an oil storage tank 11, an atomization tank 12 and a connecting channel 13 connecting the oil storage tank 11 and the atomization tank 12. The oil storage tank 11 and the atomization tank 12 of the present invention are arranged in an upper and lower state, and the atomization tank 12 is located below the oil storage tank 11. The oil storage tank 11 can be pre-filled with e-liquid, and the oil inlet hole 21 of the atomization core 20 is connected to the atomization tank 12 to ensure that it can receive e-liquid.

[0035] A sealing assembly 40 is also provided in the oil tank housing 10. The sealing assembly 40 includes a sealing member 41 and an elastic member 42. The sealing member 41 is slidably provided in the atomization bin 12 and can be slidably blocked or disengaged from the connecting channel 13. The elastic member 42 is sleeved on the outside of the sealing member 41 so that the sealing member 41 blocks the connecting channel 13 in the initial state. The elastic member 42 is preferably a spring.

[0036] like Figure 2 As shown, when not in use, the elastic force of the elastic member 42 causes the sealing member 41 to block the communicating channel 13, so that the oil storage bin 11 and the atomization bin 12 are separated. At this time, the atomizer core 20 in the atomization bin 12 does not come into contact with the e-liquid pre-injected into the oil storage bin 11, thereby avoiding e-liquid leakage and e-liquid contamination caused by high temperature or high pressure, ensuring that the atomizer core 20 has a good atomization effect and is easy to carry and transport.

[0037] like Figure 3 As shown, when it is needed, the sealing member 41 can be slid out of the connecting passage 13 so that the oil storage tank 11 is connected with the atomization tank 12. At this time, the e-liquid in the oil storage tank 11 can flow into the atomization tank 12 through the connecting passage 13 and flow into the interior of the atomization core 20 through the oil inlet hole 21, so that the atomization core 20 can work normally.

[0038] In this embodiment, the atomizer core 20 is arranged on the side of the oil storage tank 11 and the atomizer tank 12, and an exhaust channel 14 is provided in the upper end of the oil tank shell 10. The base 30 is provided with a mounting hole 38 corresponding to the exhaust channel 14. The upper end of the atomizer core 20 is inserted into the exhaust channel 14 and fixed, and the lower end of the atomizer core 20 is installed in the mounting hole 38. The oil inlet hole 21 on the side of the atomizer core 20 is connected to the atomizer tank 12. The dual-oil tank cartridge 100 of the present invention has a compact structure and is easy to carry and use.

[0039] During installation, the atomizer core 20 is inserted from the installation hole 38 , and the upper end of the atomizer core 20 is inserted into the exhaust passage 14 and fixed, thereby completing the installation of the atomizer core 20 , which is convenient and quick.

[0040] An air inlet channel 15 and an air inlet 16 connected to the air inlet channel 15 are provided on the side of the oil tank shell 10, which does not need to be provided at the bottom of the base 30. A sliding cover 17 is provided at the air inlet 16. When not in use, the sliding cover 17 covers the air inlet 16 to prevent foreign matter from entering the dual oil tank cartridge 100 and causing contamination.

[0041] In this embodiment, the oil tank shell 10 is provided with an oil filling hole 18 and an oil filling cap 19 covering the oil filling hole 18 corresponding to the oil storage tank 11. The user can add oil into the oil storage tank 11 through the oil filling hole 18 to ensure the continuous use of the dual oil tank cartridge 100.

[0042] As an embodiment, the base 30 is provided with a sliding cavity 31 connected to the atomization bin 12, the sliding cavity 31 is arranged corresponding to the connecting channel 13, and the bottom of the base 30 is provided with a through hole 32 connected to the sliding cavity 31, and the sealing member 41 is slidably provided in the sliding cavity 31, and the user can control the sealing member 41 through the through hole 32.

[0043] Preferably, the outer wall of the sealing member 41 is provided with a first sealing ring 43 and a second sealing ring 44. The first sealing ring 43 is used to abut and seal against the communicating channel 13 to prevent the oil in the oil storage bin 11 from leaking into the atomizing bin 12, thereby preventing oil leakage during transportation or carrying. The second sealing ring 44 is used to abut and seal against the sliding cavity 31 to prevent the oil in the atomizing bin 12 from leaking into the sliding cavity 31 or even leaking outside the oil bin housing 10, thereby improving the sealing effect.

[0044] In this embodiment, the outer wall of the sealing member 41 is provided with a plurality of grooves 411 for mounting the first sealing ring 43 and the second sealing ring 44 respectively, so that the mounting is stable.

[0045] Furthermore, the base 30 is provided with a guide block 33 inside the sliding cavity 31, and the outer wall of the seal 41 is provided with a guide groove 45. The guide block 33 cooperates with the guide groove 45 to enable the seal 41 to slide along the sliding cavity 31, preventing the seal 41 from deviating during sliding, and playing a guiding role.

[0046] Of course, the guide block 33 can be provided on the sealing member 41 , and the guide groove 45 can be provided in the sliding cavity 31 , and the specific settings can be made according to actual conditions.

[0048] Please refer to Figure 4 The seal 41 of the present invention preferably adopts a rod-shaped structure, and a first flange 48 is provided at the upper end of the seal 41. The first flange 48 is used to abut against the edge of the connecting channel 13 to prevent the seal 41 from sliding into the oil storage tank 11 as a whole and losing its separation function.

[0049] A second flange 49 is provided in the middle of the sealing member 41. The base 30 is provided with a platform 34 at the bottom of the sliding cavity 31. The elastic member 42 is sleeved over the sealing member 41, with the upper end of the elastic member 42 abutting and securing against the second flange 49, and the lower end of the elastic member 42 abutting and securing against the platform 34, thereby stably securing the elastic member 42. Furthermore, the provision of the second flange 49 and the platform 34 prevents the sealing member 41 from slipping out of the oil tank housing 10, thereby preventing it from falling off and being lost.

[0050] Specifically, the base 30 includes a bracket 35 and a fixing seat 36. The bracket 35 is connected to the fixing seat 36 and is installed at the lower part of the oil tank shell 10. The oil storage tank 11 is formed inside the oil tank shell 10. The bracket 35 and the lower part of the oil tank shell 10 form the atomization tank 12. The upper surface of the bracket 35 is an inclined surface 37 at the bottom of the atomization tank 12. The smoke oil flows along the inclined surface 37, which can increase the flow speed and reduce the core lubrication time of the atomization core 20.

[0051] In this embodiment, a condensation chamber 39 is formed between the bracket 35 and the fixing seat 36 for collecting condensed liquid and leaked e-liquid.

[0052] Please refer to Figure 6 The present invention further provides an electronic atomization device 200, comprising a main unit 201 and the aforementioned dual-tank cartridge 100, wherein the dual-tank cartridge 100 is mounted on the main unit 201, and the main unit 201 provides power to the dual-tank cartridge 100. The electronic atomization device 200 of the present invention also has the aforementioned beneficial effects, which will not be detailed here.

[0053] In this embodiment, a first magnet 310 is provided on the base 30, and a second magnet 204 is provided on the host 201. The first magnet 310 and the second magnet 204 are magnetically connected to fix the dual oil tank cartridge 100 and the host 201, making installation and disassembly convenient and quick.

[0054] In this embodiment, a first electrode 22 is provided at the bottom of the atomizing core 20, and the first electrode 22 is electrically connected to the heating wire. The first electrode 22 is exposed at the bottom of the base 30. The host 201 is provided with a battery and a second electrode 205.
