Two channels 203 for air flow are provided at the bottom of the first sealing member 2. Two convex portions 202 which are hollow inside and are integrally formed with the first sealing member 2 for communicating the channels 203 are provided on the upper part of the first sealing member 2. One side of each convex portion 202 is vertically cut, and the cut part forms a separation piece 201 for isolating the reverse air flow. Among them, the one-way air flow can pass through the channels 203 and pass through the cut gap between the convex portion 202 and the separation piece 201.

[0026] The upper ends of the first air guiding member 5 and the second air guiding member 6 are respectively inserted into each channel 203. The hollow regions inside the first air guiding member 5 and the second air guiding member 6 are communicated with the channel 203 for exhausting smoke. A second sealing member 7 for sealing the lower ports of the first oil storage cavity 301 and the second oil storage cavity 401 is installed at the lower ends of the first cartridge 3 and the second cartridge 4. The lower ports of the first air guiding member 5 and the second air guiding member 6 are sleeved on the upper end of the second sealing member 7 and fixed. Two air inlet through holes 701 for air intake are formed at the bottom of the second sealing member 7. Each through hole 701 is communicated with the hollow regions inside the first air guiding member 5 and the second air guiding member 6 for guiding air. The first cartridge 3 and the second cartridge 4 are both installed and fixed in the main body member 1. A smoking port 101 for smoking is provided at the top of the main body member 1. The fixing member 9 is installed and fixed inside the bottom of the main body member 1. The sealing ring 8 is installed between the outer wall of the fixing member 9 and the inner wall of the main body member 1 for sealing. The first electrode 10, the second electrode 11 and the third electrode 12 are installed at the bottom of the fixing member 9 for electrically connecting with the first heating element 502 and the second heating element 602 respectively.

[0027] A first air inlet 901 for air intake is formed at the bottom of the fixing member 9. The first air inlet 901 is communicated with the through hole 701. A main body support 20 for fixing the battery cell 18 and the control board 19 is installed inside the main body shell 17. The battery cell 18 and the control board 19 are both installed inside the main body support 20 for supplying power and controlling the operation of the first cartridge 5 and the second cartridge 6 respectively. A gas guiding column 13 for guiding air and the fourth electrode 14, the fifth electrode 15 and the sixth electrode 16 electrically connected with the first electrode 14, the second electrode 15 and the third electrode 16 are installed at the top of the main body support 20. The output end of the battery cell 18 is welded to the input end of the control board 19 for power supply. The output end of the control board 19 is welded to the fourth electrode 14, the fifth electrode 15 and the sixth electrode 16 for power supply.

[0028] The internal space of the main body shell 17 above the top of the main body support 20 inside the main body shell 17 forms a receiving cavity 2101 for receiving and fixing the main body member 1. The main body member 1 is installed and fixed in the receiving cavity 2101 of the main body shell 17. And the first electrode 14, the second electrode 15 and the third electrode 16 at the bottom of the main body member 1 are in contact with the fourth electrode 14, the fifth electrode 15 and the sixth electrode 16 for conducting electricity. Wherein a second air inlet hole 1701 is formed on the outer wall of the main body shell 17. The second air inlet hole 1701 is communicated with the first air inlet 901. An air flow switch 1901 is provided on the control board 19. An opening 2001 for air intake flow and charging is provided at the bottom of the main body support 20. The opening 2001 is communicated with the internal space of the main body shell 17 and the gas guiding column 13. The atmosphere can enter the internal space of the main body shell 17 from the opening 2001 to open the air flow switch 1901, so that the first heating element 502 and the second heating element 602 conduct electricity and work.

[0029] Such as Figure 4As shown, when smoking, the forward airflow enters the hollow part inside the protrusion 202 from the channel 203 at the bottom of the first seal 2, opening the isolation piece 201 and allowing the airflow to go upward.

[0030] As Figure 5 shown, when the reverse airflow passes through the upper part of the first seal 2, the air pressure will squeeze the isolation piece 201 against the protrusion 202, closing the cutting gap between the protrusion 202 and the isolation piece 201, and preventing the reverse airflow from entering the channel 203.

[0031] As Figure 6 , when smoking from the smoking port 101 at the top of the main body part 1, outside air can enter from the opening 2001 and the second air inlet hole 1701 respectively. The airflow entering from the opening 2001 enters the main body shell 17. By controlling the airflow switch 1901 on the control board 19 to open, the first heating element 502 and the second heating element 602 are electrically conductive and work to heat the e-liquid to produce smoke. At the same time, the airflow enters the first air inlet 901 through the air guiding column 13 and converges with the airflow entering from the second air inlet hole 1701. Then, it enters the hollow regions inside the first air guiding member 5 and the second air guiding member 6 through two air inlet through holes 701 provided at the bottom of the second seal 7, driving the smoke produced by heating the e-liquid by the first heating element 502 and the second heating element 602. The smoke enters the hollow part inside the protrusion 202 from the channel 203 at the bottom of the first seal 2, opening the isolation piece 201, and is finally inhaled from the smoking port 101.

[0032] The possible beneficial effects brought by the unidirectional air guiding dual e-cigarette cartridges disclosed in this application include but are not limited to: The unidirectional air guiding dual e-cigarette cartridges of the present invention can achieve simultaneous heating of each e-cigarette cartridge when powered on by designing dual e-cigarette cartridges and a unidirectional air guiding part, generating a large amount of smoke and having a good taste. When smoking towards the air guiding part, only the unidirectional airflow (i.e., the forward airflow) can pass through to open the airflow switch and make the atomizer work, and the reverse airflow cannot pass through the unidirectional air guiding part to open the airflow switch and make the atomizer work, solving the problem of poor user experience.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
