Description

TECHNICAL FIELD



[0001] The utility relates to the field of cigarette substitutes, and specifically to a vaporization device and a cartridge thereof.

BACKGROUND ART



[0002] The electronic cigarette is also called as a virtual cigarette or a vaporization device. As a substitute of the cigarette, the electronic cigarette is mostly used for smoking cessation. The electronic cigarette has similar appearance and taste with the cigarette, but often does not contain other harmful ingredients, such as, tar, suspended particles, and the like, in the cigarette.

[0003] The vaporization device is mainly formed of a cartridge and a body with a power supply and a puff sensor therein. Condensate produced during drawing by a user is accumulated on a ventilation hole. During drawing, aerosol-generating substrate (usually a liquid) has the phenomenon of frying oil due to atomization, and the aerosol-generating substrate is sputtered onto the ventilation hole at an atomizer base. If placed for a long time, the vaporization device also has the phenomenon of liquid leakage due to action of a negative pressure. The leakage liquid can be leaked to the outside of the vaporization device through the ventilation hole, and/or flow to the body, which causes damage to the body and the puff sensor thereof and brings a bad usage experience to the user.

[0004] In addition, since the previous ventilation hole is disposed under an atomizing core, more condensate is often accumulated under the atomizing core, and During drawing, due to issue of accumulation of the condensate, airflow of the ventilation hole is affected by the condensate, causing blockage of the airflow.

DETAILED EMBODIMENT OF THE UTILITY



[0024] To clearly understand technical features, objects and effects of the utility, now detailed embodiments of the utility are explicitly explained with reference to the accompanying drawings.

[0025] As shown in FIGS. 1-3, a vaporization device in one preferable embodiment of the utility comprises a cartridge 1 and a body 2. The body 2 comprises a power supply configured to electrically connect with the cartridge 1 and supply power to the cartridge 1. The cartridge 1 comprises a connecting end butted with the body 2, and after the connecting end is butted with the body 2, the body 2 can power the cartridge 1.

[0026] The cartridge 1 comprises an atomization base 11, and an atomization assembly 12 disposed on the atomization base 11 for heating and atomizing aerosol-generating substrate (usually a liquid), and the cartridge 1 is provided with an airflow channel 13 passing through the atomization base 11. When gas flows, an aerosol produced by the atomization assembly 12 on the atomization base 11 for heating aerosol-generating substrate is brought to a suction nozzle 14 for user drawing.

[0027] The atomization base 11 defines at least one ventilation hole 111. A ventilation pipe 15 extends from the ventilation hole 111, resulting in one end of the ventilation pipe 15 extending into the airflow channel 13, and the other end being in fluid communication with a puff sensor 21 in the body 2. The puff sensor 21 is a microphone arranged in the body 2, and when the puff sensor 21 senses a gas flowing and transmits a signal to a controller, the body 2 is turned on to power the cartridge 1.

[0028] The ventilation pipe 15 is disposed on the atomization base 11, and extends into the airflow channel 13 to locate above a surface of the atomization base 11, wherein the surface of the atomization base 11 defines at least a side of airflow channel 13. That is, the ventilation pipe 15 is higher than the surface of the atomization base 11. So if the cartridge 1 has a liquid leakage, it is not easy to enter into the ventilation pipe 15, such that the risk of entering from the ventilation pipe 15 into the body 2 can be reduced.

[0029] The ventilation pipe 15 is an independent component, and the ventilation pipe 15 is plugged into the atomization base 11 to make production and installation simpler. Generally, the ventilation pipe 15 is made of a metal material, preferably, stainless steel, which is easily formed and prevents rust.

[0030] The ventilation pipe 15 and the atomization assembly 12 are staggered in a flow direction of the airflow channel 13, for example, the ventilation pipe 15 isn't located right below the atomization assembly 12 in this embodiment, so as to avoid condensed liquid below the atomization assembly 12 from directly falling into the ventilation pipe 15, to reduce the risk of the liquid flowing from the ventilation pipe 15 to one side of the body 2, and to reduce the risk of blockage of the ventilation pipe 15 by the liquid, so as to improve smoothness of the airflow.

[0031] The airflow channel 13 comprises an atomization channel 131 passing through the atomization base 11, and an air inlet channel 132 and an air outlet channel 133 respectively in communication with two ends of the atomization channel 131. When a user draws, the environment air flows sequentially through the air inlet channel 132, the atomization channel 131, and the air outlet channel 133 to the suction nozzle 14, bringing the aerosol atomized by the atomization assembly 12 to be drawn by the user.

[0032] The ventilation pipe 15 and the atomization assembly 12 are arranged along a flow direction of the air inlet channel 132 towards the air outlet channel 133, such that the ventilation pipe 15 is on one side of the atomization base 11. Before reaching the atomization assembly 12, a part of gas flows to the body 2 via the ventilation pipe 15, to turn on the puff sensor 21, and another part of other gas flows to the atomization assembly 12 to participate in heating and atomizing. Therefore, gas has flown to the body 2 before reaching the atomization assembly 12, and the ventilation pipe is above the atomization base 11, so that it won't have aerosol-generating substrate flowing into the ventilation pipe 15, which reduces influence of the condensate on the airflow. In this embodiment, the atomization channel 131 transversely passes through the atomization base 11, and an extending direction of the atomization channel 131 is perpendicular to an axial direction of the vaporization device.

[0033] Disposing the ventilation pipe 15 on one side of the atomization base 11 makes airflow of the entire cartridge 1 more smooth. Disposing the ventilation pipe 15 on one side of the atomization base 11 can reduce influence of the condensate on the airflow, so as to make the airflow more smooth, and have a better atomization effect.

[0034] In other embodiments, when there are a plurality of ventilation holes 111 and ventilation pipes 15, respectively, the ventilation pipes 15 also can be respectively disposed on two sides of the atomization base 11, or the plurality of ventilation pipes 15 are on the same side of the atomization base 11.

[0035] The ventilation pipe 15 is an elongated pipe. As the ventilation pipe 15 is thin and long, little condensate is attached on the ventilation pipe 15 because of surface tension, and does not easily enter into the body 2. Since the ventilation pipe is thin and long, and is above a surface of the atomization base 11, when the atomization base 11 has liquid leakage, it is also not easy to enter into the ventilation pipe 15 even if shaking in transportation.

[0036] In some embodiments, the ventilation pipe 15 has an inner diameter from 0.6 mm to 1.0 mm, such as, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or the like, and a length from 3 mm to 8 mm, such as, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, or the like. In these ranges, ventilation effect can be ensured, and liquid leakage also can be effectively prevented.

[0037] In some embodiments, the ventilation pipe 15 is further provided with a breathable separator 151 that prevents liquid from flowing out via the ventilation pipe 15. When there are more condensate, the separator 151 can further prevent leaking liquid and condensate from flowing to the body 2. Preferably, the separator 151 comprises a breathable cotton or a breathable membrane disposed on one end of the ventilation pipe 15 close to the body 2, which can breathe, and also can prevent liquid from flowing.

[0038] Preferably, a gap is reserved between one end of the ventilation pipe 15 away from the airflow channel 13 and an end surface of the connecting end, where an airflow slot 16 in communication with the ventilation pipe 15 in the end surface of the connecting end is provided, to enable gas to flow to the puff sensor 21 through the ventilation pipe 15.

[0039] It shall be understood that the above respective technical features can be combined optionally for use without limitation.

[0040] The disclosures are only embodiments of the utility, rather than limiting the extent of the utility. Any equivalent structures or equivalent flow changes using the specification and the drawings of the utility, or directly or indirectly application in other relevant technical fields shall also be included in the extent of protection of the utility.
