Atomizing component and electronic cigarette

The present application is disclosed an atomizing component and an electronic cigarette. The atomizing component comprises a light-permeable e-liquid storage sleeve. An atomizing core is detachably connected to an end of the e-liquid storage sleeve. A fastening element for restricting radial expansion of the e-liquid storage sleeve is sleeved at where the e-liquid storage sleeve is insertedly connected to the atomizing core. An end of a ventilation pipe opposite to the atomizing core is a smoke emitting outlet in communication with a suction nozzle. An e-liquid filler hole is extended from the end of the ventilation pipe provided with the smoke emitting outlet. The smoke emitting outlet and the e-liquid filler hole are located on planes of different heights; while e-liquid is being added, the outer circumferential wall of the ventilation pipe blocks the e-liquid splashed accidentally, thus preventing the e-liquid from being splashed into the ventilation pipe.

FIELD OF THE INVENTION

The present application relates to a technical field of an electronic cigarette, and more particularly relates to an atomizing component and an electronic cigarette.

BACKGROUND OF THE INVENTION

At present, electronic cigarettes on the market comprises an electronic cigarette in which atomizing component is detachably connected to the battery assembly, or an electronic cigarette in which the battery assembly shares one outer casing with the atomizing component, and the atomizing component of the electronic cigarette comprises an atomizing core. When the electronic cigarette is working, the heat generating element in the atomizing core is heated to atomize e-liquid and smoke obtained by the atomization is discharged through an air passage to achieve effect of producing smoke.

The e-liquid required for the atomization of a refillable electronic cigarette is stored in the e-liquid storage chamber in the atomizing component. When the e-liquid in the e-liquid storage chamber is exhausted, new e-liquid can be refilled into the e-liquid storage chamber so that the electronic cigarette can continue to be used.

However, the smoke emitting outlet of the air passage of the atomizing component of an ordinary electronic cigarette is located in the e-liquid storage chamber and an e-liquid filling hole, and there is no isolation device to isolate the air passage from the e-liquid filling hole, then the operation of adding the e-liquid is extremely inconvenient. When the e-liquid is added to the e-liquid storage chamber of the atomizing component, the smoke can easily splash into the air passage or the e-liquid is easily to be mistakenly added to the air passage because the air passage is not sealed or the air passage is not isolated from the e-liquid filling hole, then it affects an atomizing effect of a heating wire assembly within the atomizing component and even makes the whole electronic cigarette scrapped.

The pressing member36is generally a hollow structure and is sleeved on an end of the first case311close to the suction nozzle1, one end of the pressing member36is abutted against the heating wire assembly32to fix the heating wire assembly32, the other end of the pressing member36is abutted against the ventilation tube22to prevent the ventilation tube22from moving toward a side opposite to the suction nozzle1.

Specifically, as shown inFIG. 8, in the present embodiment, the ventilation tube22comprises a first tube223and a second tube224connected to each other, and the diameter of the first tube223is smaller than the diameter of the second tube224. The first tube223is formed at one end of the suction nozzle22near the suction nozzle1, and the first tube223passes through the perforation453of the clamp member45; the second tube body224is an end of the ventilation tube22opposite to the suction nozzle1, the second tube224is defined outside the pressing member36so that the pressing member36is abutted against a connection of the first body223and the second body224to prevent the ventilation tube22from moving to the side opposite to the suction nozzle1.

The sealing ring37is roughly a ring structure which is sleeved on a connection between the pressing member36and the first case311to prevent the e-liquid from leaking from the connection between the pressing member36and the first case311, the second tube224of the ventilation tube22is sleeved from an end of the pressing member36and then abutted against the sealing ring37, so as to prevent the sealing ring37moving.

In view of the above, the embodiment of the atomizing component and the electronic cigarette of the present invention has the following advantageous effects:

(1) One end of the ventilation tube near the suction nozzle extends outside the e-liquid filling hole, namely, the smoke emitting outlet of the ventilation tube and the e-liquid filling hole of the e-liquid storage sleeve are positioned on planes with different heights, so that the smoke emitting outlet of the ventilation tube is higher than the e-liquid filling hole, when the atomizing component is placed vertically to add smoke from the e-liquid filling hole. An outer side wall of the ventilation tube blocks the e-liquid so that the e-liquid can be prevented from splashing into the ventilation tube even if the e-liquid splash occurs accidently during the addition of the e-liquid; and one end of the e-liquid storage sleeve is detachable connected to the atomizing core so that it can be easily replaced when the atomizing core is damaged, and it also avoids problems, such as, a battery damage, a short circuit and other issues, which are caused by that the e-liquid easily leaks from the atomizing core into the battery assembly due to frequent removals of the atomizing core, when the e-liquid filling hole is provided at an insertion opening of the e-liquid storage sleeve at the atomizing core. Meanwhile, the means of adding e-liquid at the suction nozzle allows the atomizing assembly to be placed directly on a support subject to add the e-liquid when the e-liquid is added, thereby facilitating the use and more in accordance with a user's habit.

(2) Since the height difference between the smoke emitting outlet of the ventilation tube and the e-liquid filling hole of the e-liquid storage sleeve is 1.5 mm, the smoke emitting outlet of the ventilation tube is physically separated from the e-liquid filling hole of the e-liquid storage sleeve and has a distinct position, it can be convenient for the user to add e-liquid.

(3) The e-liquid storage sleeve is provided with a fastening element at a position insertedly connected to the atomizing core, the fastening element is arranged outside the e-liquid storage sleeve, and the fastening element can not only prevent an expansion of the e-liquid storage sleeve, but also can enhance connection strength between the e-liquid storage sleeve and the atomizing core, so as to prevent the atomizing core from dropping from the e-liquid storage sleeve.
