[0048] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] A flip-top disposable electronic cigarette, such as Figure 1 , Figure 3 , Figure 4 As shown, from top to bottom, it includes a flip cover 1, a mouthpiece 3, a housing 6, and a bottom cover 19.

[0050] The lower surface contour of the flip cover 1 matches the upper surface contour of the housing 6, forming a three-step structure. The height of the upper surface contour of the housing 6 decreases from left to right, increasing the coverage area of ​​the flip cover 1 on the right side of the housing 6 and improving the protection of the mouthpiece 3.

[0051] A first mounting hole 101 is provided on the left side of the flip cover 1. Correspondingly, a second mounting hole 301 is provided at the same position on the left side of the mouthpiece 3. The end plane of the first mounting hole 101 is recessed. Multiple slots that match the shape of the end plane are provided on the left end of the mouthpiece 3. The second mounting hole 301 is provided on the surface of the slot. The end plane is inserted into the slot so that the positions of the first mounting hole 101 and the second mounting hole 301 correspond. The metal shaft 2 passes through the first mounting hole 101 and the second mounting hole 301, so that the flip cover 1 and the mouthpiece 3 are hinged.

[0052] A mounting rib 302 is provided on the left side of the mouthpiece 3. Above the mounting rib 302 is a slot. The mounting rib 302 protrudes from the main structure of the mouthpiece 3 and is used to fix the mouthpiece 3. A vertical mounting groove 601 is provided on the left side of the housing 6, and the mounting rib 302 is inserted downwards into the mounting groove 601. On the right side of the mouthpiece 3, in accordance with the contour shape of the upper surface of the housing 6, an outer edge protrudes from the upper surface of the housing 6, and the inner edge is inserted into the interior of the housing 6, abutting against an annular protrusion on the inner surface of the housing 6. Through the insertion and structural cooperation of the left and right ends of the mouthpiece 3, the mouthpiece 3 is fixed on top of the housing 6.

[0053] Along the internal space of the mounting bone 302, a first mounting cavity 303 is provided at its bottom. The top of the first mounting cavity 303 is a second mounting hole 301. A slider 4 is provided in the internal space of the mounting bone 302. The bottom of the slider 4 is a second mounting cavity 401. The top of the spring 5 is embedded in the second mounting cavity 401. The bottom of the spring 5 is located in the first mounting cavity 303 of the mounting bone 302.

[0054] Inside the shell 6, the electrical structure is located on the left, while the oil storage and extraction structure is on the right, with the middle separated by a compartment to form an independent space.

[0055] On the left side inside the housing 6, below the first mounting slot 601, a pad 13 is provided as a buffer between the mouthpiece 3 and the flip cover 1. Below the pad 13 is the battery 14, and below the battery 14 is a circuit board 16. The battery 14 is connected to the atomizer core 11 through the circuit board 16.

[0056] The right side of the interior of the casing 6 houses an oil storage and extraction structure, with the larger main part being the oil tank 9. Oil tank 9 stores e-liquid using oil-absorbing cotton 10. When the oil-absorbing cotton 10 is full of e-liquid, the e-liquid remains in the oil tank 9. Compared to purely liquid e-liquid, the oil-absorbing cotton 10 has relatively lower requirements for sealing and less impact on other structures. Above the oil tank 9 is the mouthpiece 3. A first oil tank plug 8 seals the upper part of the oil tank 9 at the bottom of the mouthpiece 3. Above the first oil tank plug 8 is a first oil-absorbing cotton 7 to prevent backflow and overflow of e-liquid.

[0057] The upper end of the first oil tank plug 8 seals the space between the inside of the oil tank 9 and the mouthpiece 3, and a third mounting cavity 801 is provided. The third mounting cavity 801 is provided with a first oil-absorbing cotton 7, and a positioning post 802 is provided at the lower end for connecting with the hollow tube 1001 and the atomizing core 11 of the oil tank 9. A second air passage 803 is provided at the center of the positioning post 802.

[0058] The center of the oil tank 9, which is also the center of the oil storage cotton 10, is a hollow tube 1001 for gas circulation. Inside the hollow tube 1001 is an atomizing core 11 that converts the e-liquid into gas.

[0059] The bottom of the oil tank 9 is a second oil tank plug 12. A fourth vent 1201 is formed in the middle of the second oil tank plug 12. The fourth vent 1201 is aligned with the bottom of the atomizer, which is equivalent to using the bottom of the atomizer core 11 to block the fourth vent 1201. The first oil tank plug 8 and the second oil tank plug 12 block the upper and lower ends of the oil tank 9, so that the outlet of the oil tank 9 is only the hollow tube 1001 with the atomizer core 11.

[0060] The bottom of the second oil tank plug 12 has connecting holes on both the left and right sides.

[0061] The bottom of the second oil tank plug 12 is the overlapping space between the bottom of the housing 6 and the bottom cover 19. The bottom cover 19 is fastened to the bottom of the housing 6. A partition is provided inside the bottom cover 19, and a groove is provided inside the partition. When the housing 6 and the bottom cover 19 are fastened together, in addition to the external assembly, an insertion connection structure is provided inside, making the overall structure more stable and also separating the electrical structure and oil composition structure inside the housing 6.

[0062] At the bottom of the second oil tank plug 12, in the overlapping space between the shell 6 and the bottom cover 19, there is a second absorbent cotton 18 on the right side to achieve re-sealing and collection of e-liquid. The bottom of the atomizer coil 11 is a slender tubular structure, and since the bottom of the atomizer coil 11 is one of the outlets of the oil tank 9, the e-liquid in the oil tank 9 may flow into the bottom cover 19 along the atomizer coil 11. To prevent e-liquid from overflowing, a second absorbent cotton 18 is added inside the bottom cover 19 for sealing.

[0063] The porous structure of the second oil-absorbing cotton 18 connects to the hollow tube 1001, which is connected to the atomizing core 11, forming an airflow channel from the second oil-absorbing cotton 18 to the atomizing core 11, the first oil-absorbing cotton 7, and the mouthpiece 3.

[0064] A screw post 1902 and a third mounting hole 1903 are provided near the internal partition of the bottom cover 19.

[0065] On the left side of the interior space of the bottom cover 19, there is a charging silicone 17, which extends above the third mounting hole 1903 of the bottom cover 19. The charging silicone 17 has a sixth vent 1701 on its left side, a circular fifth mounting cavity 1702 in its center, and a sixth mounting cavity 1703 on its right side, positioned above the third mounting hole 1903. The sixth vent 1701, the fifth mounting cavity 1702, and the sixth mounting cavity 1703 are all connected to a seventh mounting cavity 1704. That is, the seventh mounting cavity 1704 is an inner groove at the top of the charging silicone 17, with three different shaped holes at the bottom connecting to the bottom of the charging silicone 17. The sixth vent 1701 of the charging silicone 17 is opposite to and connected to the air inlet 1901 of the bottom cover 19.

[0066] A circuit board 16 is positioned above the charging silicone 17, and the entire circuit board 16 is housed within the seventh mounting cavity 1704 of the charging silicone 17. A microphone 1601 is located on the upper left surface of the circuit board 16, and a TYPE-C charging port 1602 is located on the lower right surface of the circuit board 16. A screw hole 1603 is located in the center. The screw hole 1603 is positioned opposite the fifth mounting cavity 1702 of the charging silicone 17 below. The TYPE-C charging port 1602 can pass through the sixth mounting cavity 1703 of the charging silicone 17 and be inserted into the third mounting hole 1903 of the bottom cover 19, making the TYPE-C charging port 1602 flush with the bottom cover 19. Screw posts 1902 on the bottom cover 19 pass through the fifth mounting cavity 1702 of the charging silicone 17 and the screw hole 1603 on the circuit board 16 from bottom to top, fixing the charging silicone 17 and the circuit board 16 inside the bottom cover 19. The microphone 1601 is positioned above the sixth vent 1701 of the charging silicone 17. When air enters the air inlet 1901, external air can pass through the sixth vent 1701 and blow towards the microphone 1601, causing the microphone 1601 to sense it.

[0067] The microphone 1601 is covered with a silicone microphone 15 on its upper part, and a fourth mounting cavity 1501 is provided at the bottom. The microphone 1601 is placed inside the fourth mounting cavity 1501, so that the silicone microphone 15 covers the microphone 1601. Above the fourth mounting cavity 1501 is a fifth vent 1502, forming an airflow channel from the air inlet 1901 to the sixth vent 1701, then to the fourth mounting cavity 1501, and finally to the fifth vent 1502. The microphone 1601, placed in this airflow channel, can sense the air flow.

[0068] The battery electrode is located above the microphone silicone 15. The electrode is inserted into the space above the fifth vent hole 1502. The top surface of the microphone silicone 15 forms a groove in the left and right direction.

[0069] like Figure 2 As shown, when the user flips the flip cover 1 along the left side, the slider 4 at the bottom of the flip cover 1 moves downward along the space inside the mounting bone 302, compressing the spring 5. The upper part of the slider 4 tilts to the left, and the flip cover 1 slides to the lower left along the upper part of the slider 4 during the rotation, causing the center of gravity of the flip cover 1 to gradually move to the lower left. Finally, the weight of the flip cover 1 and the supporting force of the spring 5 reach a balance, and the surface of the flip cover 1 also tilts to the lower left along the upper surface of the slider 4, with the center of gravity shifting to the left end. Without the action of external force, the flip cover 1 maintains this state, allowing the mouthpiece 3 to be exposed.

[0070] After the flip cover 1 is opened, the user inhales through the mouthpiece 3. Due to the negative pressure at the mouthpiece 3, external gas enters through the air inlet 1901. The gas flow path is as follows: air inlet 1901 — sixth air passage 1701 of charging silicone 17 — microphone 1601 of circuit board 16 — fifth air passage 1502 of microphone silicone 15 — along the space inside the bottom cover 19 outside the microphone silicone 15 — the left and right connecting hole at the bottom of the second oil tank plug 12 — fourth air passage 1201 of the second oil tank plug 12 — hollow tube 1001 — third air passage 1101 of atomizing core 11 — second air passage of the first oil tank plug 8 — first air passage 701 of the first absorbent cotton 7 — air outlet 304 of mouthpiece 3. External gas passes through the microphone 1601, triggering the microphone 1601 to start, controlling the circuit board 16 to work, and simultaneously activating the heating element of the atomizing core 11, forming an electronic cigarette switching mechanism based on airflow.

[0071] Starting from the traditional structure of disposable electronic cigarettes, the original gas flow path should be designed as a straight airway to achieve a compact structure. However, since electronic cigarettes require the addition of a flip cover (1), the structure increases the connection between the flip cover (1) and the main body. There are two approaches: one is to superimpose the flip cover (1) onto the existing upright compact structure. The most obvious drawback of this is that the flip cover (1) lacks stability during the flipping process, requiring external force to stabilize it, causing inconvenience to the user. The other approach is to move the flip cover (1) to the outside of the main body structure, using the connection point to provide support, balancing the weight of the flip cover (1) with the support force at the connection point, thus stabilizing the position of the flip cover (1). The second approach inevitably creates a redundant connection structure compared to the original upright structure. Therefore, to regulate the internal structure of the electronic cigarette and maintain a compact design, this invention first removes the battery. The removed battery can be upgraded in size, increasing its capacity and improving product convenience. On the other hand, the circuit and airflow structures at the bottom for activation need to be redesigned. Airflow must pass through the microphone 1601 to activate the circuit board 16. Simultaneously, a narrower gas flow path must be established. Otherwise, using the entire internal space of the electronic cigarette as the gas flow channel results in very low negative pressure feedback from inhalation through the mouthpiece 3, requiring significant effort from the user to achieve gas flow, thus affecting the user experience. Therefore, in this application, the partition of the bottom cover 19, the sealing of the second oil tank plug 12, the circuit board 16 structure, and the silicone structure are used to fill and seal, forming a bent airflow channel. This fully utilizes the space below the connection of the flip cover 1 while creating a narrow gas flow channel, ensuring that airflow serves as the activation trigger mechanism.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
