Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to an external oil bin type cigarette cartridge and an electronic cigarette that guides oil at the bottom. Background Art

[0002] The electronic cigarette introduces the oil in the oil tank into the atomizer core through the atomizer core. The atomizer core is equipped with a heating wire that is electrically heated by electricity. The heating wire atomizes the oil into aerosol vapor smoke for users to inhale. The oil tank of the electronic cigarette is embodied by two types of electronic cigarettes. One is a cartridge-changing electronic cigarette including a cigarette cartridge and a power host. The oil tank is integrated into the cigarette cartridge. The cigarette cartridge is composed of a shell with a nozzle, and the shell is an oil tank for storing the oil. The oil tank is equipped with an atomizer core, and the lower end of the shell is equipped with an oil seal. The atomizer core, the nozzle, and the oil seal are equipped with a mutually communicating atomization channel. The other is an integrated electronic cigarette, including a shell, the upper end of which is the nozzle, and the shell is equipped with an oil tank, a battery, a control panel, and a microphone sensor. Whether it is a cartridge or an integrated electronic cigarette, the pre-filled type will leak out of the atomization channel during transportation due to bumps, temperature differences, air pressure and other factors after the product leaves the factory, resulting in oil leakage, product quality problems before the product reaches the sales end, greatly affecting the normal sales of the product. Therefore, it is necessary to improve the existing electronic cigarette products to solve the above problems. Utility Model Content

[0006] Further, the pore wall of the second through-hole B of the first bottom cover bulges downward.

[0007] Further, the channel tube body has a larger caliber at the upper end than at the lower end. A step position is provided around the outer wall of the channel tube body near the lower port. The step position is used to block the first through-hole A of the first oil seal to achieve the sealing between the edge of the first through-hole A and the outer wall of the channel tube body.

[0008] Further, the second sealing base includes a second oil seal and a second bottom cover. The second oil seal is provided with a plugging through-hole position, and a hollow cylinder is embedded in the plugging through-hole position.

[0013] An electronic cigarette includes the above-mentioned external oil storage chamber type cartridge with bottom oil guiding.

[0014] The external oil storage chamber type cartridge and electronic cigarette with bottom oil guiding designed by this technical solution have the beneficial effect that the cartridge of the electronic cigarette is composed of two parts. One part is the mouthpiece and the external oil storage chamber. Since the oil storage chamber formed inside only needs to seal the opening at its lower end, the e-liquid stored in the external oil storage chamber has better sealing performance. The traditional atomization core is arranged in the pre-filled e-liquid storage chamber, and the e-liquid is guided to the atomization core, which is sensitive to factors such as transportation jolts, temperature, and air pressure differences. Under the influence of these factors, the atomization core is prone to e-liquid leakage. In this solution, the external oil storage chamber removes the atomization core, and the atomization core assembly is arranged in the atomization oil chamber part without oil. In this way, the external oil storage chamber is filled with oil and leaves the factory, and its sealing performance is less affected by factors such as transportation jolts, temperature differences, and air pressure differences. Therefore, this solution is beneficial to prevent the cartridge from leaking e-liquid when it reaches the merchant or the consumer after being pre-filled with e-liquid in the electronic cigarette components, thereby improving the product quality and consumption experience.

[0015] On the other hand, the cartridge composed of the external oil storage chamber and the atomization oil chamber designed by this solution can achieve a large e-liquid storage capacity. Part of the e-liquid is stored in the external oil storage chamber, part is input into the middle oil chamber of the atomization oil chamber, and part enters the atomization oil chamber from the middle oil chamber, forming multiple separated oil chambers, which is beneficial to maintaining the quality and freshness of the e-liquid and achieving better consistency in atomization taste.

[0024] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only partial embodiments of the present disclosure, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts also belong to the scope of protection of the present disclosure.

[0025] Please refer to Figures 1 to 8 , which is a specific embodiment of an externally-mounted oil tank type cartridge with bottom oil guiding provided by the present technical solution. In this embodiment, the externally-mounted oil tank type cartridge with bottom oil guiding includes an external oil tank 01 and an atomizing oil tank 02 inserted and connected to the external oil tank 01. The external oil tank 01 includes a first housing 2. The upper end of the first housing 2 is provided with a mouthpiece portion 201. A channel tube body 202 extends downward from the suction port of the mouthpiece portion 201. A first oil storage cavity is formed between the inner wall of the first housing 2 and the outer wall of the channel tube body 202. The lower end of the first housing 2 is provided with a first sealing base 34. The first sealing base 34 is provided with a first through hole 341 through which the channel tube body 202 passes, and a second through hole 342 for injecting oil into the first oil storage cavity. A first sealing plug 5 is provided at the second through hole 342. The atomizing oil tank includes a second housing 8. The upper end of the second housing 8 is provided with a third through hole 801 for inserting the lower end of the channel tube body 202, and a fourth through hole 802 for inserting and docking with the second through hole 342. An atomizing core is arranged inside the second housing 8. The upper end of the atomizing core is butted against the lower end of the third through hole 801. A second oil storage cavity is formed inside the second housing 8. The lower end of the second housing 8 is provided with a second sealing base 68. The second sealing base 68 is provided with a plugging through hole position 161 for inserting the lower end of the atomizing core. The second sealing base 68 is provided with an air inlet hole 181 communicated with the atomizing core.

[0026] The electronic cigarette cartridge designed by the present technical solution is composed of an external oil tank 01 and an atomizing oil tank 02. For the external oil tank 01, only the opening at its lower end needs to be sealed, and the oil stored in the external oil tank 01 has good sealing performance. In the traditional design, the atomizing core is arranged in the pre-filled oil storage cavity, and the oil is guided to the atomizing core. It is sensitive to factors such as transportation bumps, temperature, and air pressure differences. Under the influence of these factors, the atomizing core is prone to oil leakage. In this solution, the external oil tank 01 removes the atomizing core and arranges the atomizing core assembly in the atomizing oil tank 02 part that does not contain oil. In this way, the external oil tank 01 is filled with oil and leaves the factory. The sealing performance of the external oil tank 01 is less affected by factors such as transportation bumps, temperature differences, and air pressure differences. Therefore, this solution is beneficial to prevent the cartridge from leaking oil when it reaches the merchant or the consumer after pre-filling the electronic cigarette components, thus improving the product quality and consumer experience.
