Description

Technical Field

[0001] This utility model relates to the field of electronic suction device technology. Background Technology

[0002] Currently, most e-liquid cartridges in electronic vaping devices employ a single atomizer core design. This core heats and atomizes e-liquid to produce an aerosol for the user to inhale. However, existing single-core technology has significant drawbacks: First, a single core, limited by its heating area and power handling capacity, suffers from insufficient atomization efficiency under sustained high-power operation, resulting in a low atomization volume per unit time, failing to meet users' demands for high-concentration vapor. Second, when the core fails due to long-term carbon buildup, coil melting, or ceramic substrate cracking, the entire cartridge becomes unusable, forcing consumers to replace it prematurely, increasing operating costs and wasting resources. Therefore, there is room for improvement in existing electronic vaping devices. Utility Model Content

[0025] See appendix Figure 1-3The image shows a type of e-cigarette cartridge for improving atomization. The cartridge 1 has a main shell 2, with a mouthpiece 21 at the top. An oil reservoir 20 is located within the main shell 2, and a base assembly 4 is provided. The base assembly 4 seals the bottom of the oil reservoir 20. An atomizing mechanism 3 is disposed within the oil reservoir 20. The atomizing mechanism 3 includes an outer cover 30, a first atomizing core 31, and a second atomizing core 32. The outer cover 30 has a longitudinally penetrating interior. The upper part of the outer cover 30 is connected to the mouthpiece 21, and the lower part of the outer cover 30 is connected to the base assembly 4. The first atomizing core 31, the second atomizing core 32, the third atomizing core 31, the third atomizing core 32 ... Two atomizing cores 32 are arranged side by side in the outer cover 30. The lower ends of the first atomizing core 31 and the second atomizing core 32 are connected to the base assembly 4. The base assembly 4 is provided with a first air hole 401 and a second air hole 402. The first atomizing core 31 has a first atomization channel, and the second atomizing core 32 has a second atomization channel. The lower ends of the first atomization channel and the second atomization channel are respectively connected to the first air hole 401 and the second air hole 402. The upper ends of the first atomization channel and the second atomization channel are connected to the mouthpiece 21 through the upper part of the outer cover 30.

[0026] The upper part of the main shell 2 forms a mouthpiece 21, and the interior of the main shell 2 forms a receiving space. The bottom of the main shell 2 is sealed by the base assembly 4 to form an oil storage tank 20. An atomizing mechanism 3 is installed in the oil storage tank 20. The lower part of the atomizing mechanism 3 is installed on the base assembly 4, and the upper part of the atomizing mechanism 3 is in communication with the mouthpiece 21 so that the smoke generated by atomization flows into the mouthpiece 21.

[0027] The atomizing mechanism 3 includes a longitudinally penetrating outer cover 30, within which a first atomizing core 31 and a second atomizing core 32 are arranged side-by-side. The lower ends of both are mounted on the base assembly 4. The first atomizing channel communicates with the first air vent 401, and the second atomizing channel communicates with the second air vent 402, allowing external airflow to enter the first and second atomizing cores 31 and 32. The upper ends of both extend upwards within the outer cover 30, which is longitudinally penetrating, allowing the first and second atomizing channels to connect with the mouthpiece 21 via the upper part of the outer cover 30. That is, the vapor generated by atomization flows out of the first and second atomizing channels, reaches the upper part of the outer cover 30, and then flows into the mouthpiece 21. Using two atomizing cores significantly increases the atomization volume, and even if one atomizing core fails, the other can still ensure atomization operation, thus extending the product's lifespan.

[0028] In some embodiments, the outer cover 30 is provided with a sealing positioning member 33, the outer wall of the sealing positioning member 33 is in close contact with the inner wall of the upper part of the outer cover 30; the sealing positioning member 33 is provided with a first insertion channel and a second insertion channel, and the first atomizing core 31 and the second atomizing core 32 are respectively tightly inserted into the first insertion channel and the second insertion channel.

[0029] The sealing and positioning component 33 is generally made of rubber, with a first and a second insertion channel running longitudinally through the middle. The first atomizing core 31 and the second atomizing core 32 are inserted into these channels to stabilize their positions. At the same time, the sealing and positioning component 33 is tightly inserted into the outer cover 30, and the tight fit between the sealing and positioning component 33 and the outer cover 30 not only strengthens the stability of the two atomizing cores but also enhances the sealing effect, preventing e-liquid from leaking into the mouthpiece 21.

[0030] In some embodiments, the lower part of the outer cover 30 is provided with an oil inlet window 301 to allow e-liquid in the oil storage tank 20 to permeate into the first atomizing core 31 and the second atomizing core 32. The oil inlet window 301 is positioned lower than the sealing positioning member 33 so that the sealing positioning member 33 forms a seal on the e-liquid, preventing the e-liquid from leaking upwards into the mouthpiece. Multiple oil inlet windows 301 can be provided to ensure that sufficient e-liquid continuously permeates into the two atomizing cores.

[0031] Furthermore, an oil seepage space is formed between the outer cover 30 and the first atomizing core 31 and the second atomizing core 32. The oil seepage space is connected to the oil inlet window 301. Both the first atomizing core 31 and the second atomizing core 32 are provided with oil holes, which are connected to the oil seepage space.

[0032] Specifically, the sealing positioning component 33 is positioned to correspond to the inner wall of the upper part of the outer cover 30, so that an oil seepage space is formed in the lower part of the outer cover 30. At the position corresponding to the oil seepage space, the first atomizing core 31 and the second atomizing core 32 are provided with oil holes. The e-liquid in the oil storage tank 20 enters the oil seepage space through the oil inlet window 301, and then enters the first atomizing core 31 and the second atomizing core 32 through the oil holes.

[0033] In some embodiments, the base assembly 4 includes an upper body 40 and a lower body 41, with the lower body 41 supporting the lower part of the upper body 40. The upper body 40 has a cavity in its middle, with an opening at the top and a first air hole 401 and a second air hole 402 at the bottom. A sealing base 42 is installed in the cavity through the opening, and the sealing base 42 has a first through hole and a second through hole, which correspond to the first air hole 401 and the second air hole 402, respectively. The first atomizing core 31 and the second atomizing core 32 are respectively inserted into the first through hole and the second through hole.

[0034] The upper body 40 is generally made of rubber, and its sidewalls fit snugly against the inner wall of the main shell 2, reinforcing the seal of the oil reservoir 20 and preventing e-liquid from leaking downwards. The lower body 41 is made of hard plastic or metal and can be connected to the main shell 2 by means of tight fit or snap-fit, providing support and ensuring structural stability. A cavity is formed on the upper body 40, and the lower end of the atomizing mechanism 3 is installed in the cavity. The outer cover 30 fits into the sealing base 42. The lower ends of the first atomizing core 31 and the second atomizing core 32 are inserted into the first through hole and the second through hole, respectively, ensuring the sealing of the lower part of the atomizing mechanism 3 and preventing e-liquid from leaking downwards. A first air hole 401 and a second air hole 402 are respectively opened at the bottom of the cavity of the upper body 40. The first air hole 401 corresponds to the first through hole so that the external airflow flows through the first air hole 401 into the first atomizing core 31 (first atomizing channel). The second air hole 402 corresponds to the second through hole so that the external airflow flows through the second air hole 402 into the second atomizing core 32 (second atomizing channel).

[0035] In some embodiments, the upper part of the sealing base 42 is tapered inward to form a stepped portion, meaning the radial dimension of the upper part of the sealing base 42 is smaller than that of its lower part. The outer cover 30 is fitted around the upper periphery of the sealing base 42, and the bottom of the outer cover 30 abuts against the surface of the stepped portion. The outer cover 30 fits tightly with the upper part of the sealing base 42 to ensure a tight seal, while the support of the stepped portion contributes to the stability of the outer cover 30 during installation. Furthermore, a sealing ring is provided between the outer cover 30 and the mouthpiece 21 to prevent e-liquid from leaking into the mouthpiece 21 and affecting the user experience.

[0036] In some embodiments, the lower base 41 is equipped with an electrode section for connection to the main unit, and both the first atomizing core 31 and the second atomizing core 32 are electrically connected to the electrode section. The electrode section includes two electrode pins mounted on the lower base 41. The heating wires of both the first atomizing core 31 and the second atomizing core 32 extend downward through corresponding atomization channels and are respectively connected to the two electrode pins. When the cartridge 1 is assembled with the main unit, the first atomizing core 31 and the second atomizing core 32 are electrically connected to the main unit through the electrode section, and the two work synchronously to increase the total amount of atomization.

[0037] An electronic vaping device is provided, including a main unit, the electronic vaping device further including a cartridge 1 as described in any of the preceding claims, the cartridge 1 being assembled and connected to the main unit.

For those skilled in the art, this utility model can have various modifications, combinations, and variations.
