DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
In order to understand the technical features, the purpose and the effect of the present invention more clearly, the specific embodiments of the present invention will be described in detail referring to the drawings.
Referring to FIGS. 1-5, the present invention relates to a battery assembly 2 configured to be combined with an atomization assembly 1 to form an electronic cigarette. The battery assembly 2 includes a battery 22, and the battery 2 includes a first battery electrode 221 and a second battery electrode 222. The battery assembly 2 further includes a first charging electrode 31 connected to the first battery electrode 221 and a second charging electrode 32 connected to the second battery electrode 222. The first charging electrode 31 is mounted at an end of the battery assembly 2 and extends to an end surface of the battery assembly 2, and the second charging electrode 32 partially or wholly surrounds a side wall of the battery assembly 2. Both the first charging electrode 31 and the second charging electrode 32 are configured for connecting with an external charger.
Referring to FIG. 4 and FIG. 5, preferably, the second charging electrode 32 is a ring-shaped conductive piece.
An end cover 23 is mounted on an end of the battery assembly 2, and the first charging electrode 31 axially runs through the end cover 23. The battery assembly 2 further includes a cigarette butt lamp configured for simulating burning tobacco, and the end cover 23 can also be a lamp cap covered on the cigarette butt lamp.
The end cover 23 includes an end cover body 231, and a diameter of an end of the end cover body 231 gradually reduces relative to the end cover body 231 to form an inserting portion 232. The battery assembly 2 further includes a battery sleeve 21 configured for accommodating the battery 22, and the inserting portion 232 is inserted inside the battery sleeve 21. In this embodiment, the inserting portion 232 is inserted in the battery sleeve 21 and forms interference fit with the battery sleeve 21.
When the battery assembly 2 and atomization assembly 1 of the present invention are combined with each other to form the electronic cigarette, the atomization assembly 1 is connected to an end of the battery assembly 2 that is far away from the end cover 23. When the electronic cigarette is charged, only one end of the electronic cigarette where the battery assembly 2 is positioned needs to be inserted in a corresponding part of a charger to charge the battery 22, so that the charging operations are easy. When the present invention is implemented in an electronic cigarette capable of being used for many times, as the atomization assembly 1 does not need to be detached from the battery assembly 2, the atomization assembly 1 is not easy to be lost. When the present invention is implemented in a disposable electronic cigarette, the atomization assembly 1 cannot be detached from the battery assembly 2. Thus, by mounting the first charging electrode 31 and the second charging electrode 32 on the battery assembly 2, the battery 22 can be conveniently charged.
The first charging electrode 31 axially runs through an end of the end cover body 231 and is electrically connected with the first battery electrode 221 of the battery 22. The first charging electrode 31 can run through the end cover body 231 by two methods. In one of the two methods, the end cover body 231 defines a first through-hole axially running through an end of the end cover body 231, and the first charging electrode 31 is inserted in the first through-hole with interference fit. In the other one of the two methods, the end cover 23 is made of soft material, and the end cover body 231 defines a second through-hole axially running through the end cover body 231; a flange protrudes from an inner wall of the end cover body 231 corresponding to the second through-hole, and the flange is disposed along a radial direction of the second through-hole; the first battery electrode 221 defines a recess corresponding the flange, and the flange is embedded into the recess.
An end surface of the first charging electrode 31 and an end surface of the battery assembly 2 cooperatively form a flat surface.
The second charging electrode 32 is sheathed on the inserting portion 232, and is electrically connected with the second battery electrode 222 of the battery 22. Two ends of the second charging electrode 32 are abutted against an end of the end cover body 231 and an end of the battery sleeve 21 respectively, so that the second charging electrode 32 is fixed between the end cover body 231 and the battery sleeve 21. For beautifying an appearance of the battery assembly 2, an outer surface of the second charging electrode 32 is positioned to be coplanar with an outer surface of the battery assembly 2.
Referring to FIG. 5, an end of the second charging electrode 32 facing the atomization assembly 1 extends inward along a radial direction of the battery assembly 2 and is bent away from the end cover body 231 along an axial direction of the battery assembly 2 to form a mounting part 321. That is, the mounting part 321 is a fold-fin. A second connecting line 42 is mounted on the mounting part 321, an accommodating portion 233 fitting a shape of the mounting part 321 is formed on the inserting portion 232, and the mounting part 321 is held in the accommodating portion 233. The accommodating portion 233 is a notch or a groove formed along an axial direction of the inserting portion 232 and opening toward an end of the inserting portion 232. In assembly of the second charging electrode 32, the second charging electrode 32 is sheathed on the inserting portion 232, and then a sub-assembly formed by the inserting portion 232 and the second battery electrode 32 is inserted in the battery sleeve 21. The mounting part 321 is completely received in the accommodating portion 233, so that the sub-assembly formed by the inserting portion 232 and the second battery electrode 32 can be conveniently inserted in the battery sleeve 21.
A control unit 24 configured for controlling the atomization assembly 1 to work is accommodated in the battery sleeve 21, and the control unit 24 is disposed between the battery 22 and the end cover 23. When the electronic cigarette is working normally, the control unit 24 is configured for controlling electricity supply from the battery 22 to the atomization assembly 1, and thereby further controlling atomizing work of the atomization assembly 1. When the electronic cigarette is charged, the control unit 24 is further configured for cutting the electricity supply from the battery 22 to the atomization assembly 1.
Specifically, the battery assembly 2 further includes an airflow sensor connected to the control unit 24. When the airflow sensor detects a change of smoking flow, the control unit 24 can control the atomization assembly 1 to start working or stop working.
Referring to FIG. 5, the first charging electrode 31 is electrically connected to the first battery electrode 221 via the control unit 24 by a first connecting line 41, and the second charging electrode 32 is electrically connected to the second battery electrode 222 by the second connecting line 42, so that the battery 22 is charged when charging the electronic cigarette.
The control unit 24 is provided with a first connecting terminal 241 and a second connecting terminal 242. An end of the battery assembly 2 far away from the end cover 23 is provided with an outer electrode 252, and the outer electrode 252 sleeves an inner electrode 251 therein. The inner electrode 251 is connected to the first connecting terminal 241 by a third connecting line 43, and the outer electrode 252 is successively connected to the second battery electrode 222 and the second connecting terminal 242 by a fourth connecting line 44. The control unit 24 is connected with the outer electrode 252, and is further connected with the atomization assembly 1, so that the control unit 24 controls the electricity supply from the battery 22 to the atomization assembly 1. In this present invention, the control unit 24 controls a voltage input by the charger, so that the battery 22 can be protected from being damaged by too high charging voltages.
In this embodiment, both a connection between the first connecting line 41 and the first charging electrode 31 and a connection between the first connecting line 41 and the first battery electrode 221 are formed by welding. Similarly, a connection between the second connecting line 42 and the second charging electrode 32, a connection between the second connecting line 42 and the second battery electrode 222, a connection between the third connecting line 43 and the inner electrode 251, a connection between the third connecting line 43 and the first connecting terminal 241, a connection between the fourth connecting line 44 and the outer electrode 252, and a connection between the fourth connecting line 44 and the second connecting terminal 242 are all formed by welding.
Moreover, in this present invention, the first battery electrode 221 means a positive electrode of the battery 22, and the second battery electrode 222 means a negative electrode of the battery 22.
This invention further relates to an electronic cigarette, and the electronic cigarette comprises the aforementioned battery assembly 2 and atomization assembly 1.
FIG. 6 shows a principle diagram of the electronic cigarette of the present invention in a no-charging status: the battery 22 is connected to the atomization assembly 1 and the control unit 24 respectively for supplying electricity to the control unit 24 and the atomization assembly 1 respectively. The airflow sensor is connected to the control unit 24, and is configured for generating a smoking start signal or a smoking end signal when the airflow sensor detects a change of air flow in smoking. Furthermore, the airflow sensor transmits the smoking start signal and the smoking end signal to the control unit 24, so that the control unit 24 controls the atomization assembly 1 to start smoking and to stop smoking according to the smoking start signal and the smoking end signal.
FIG. 7 shows a principle diagram of the electronic cigarette of the present invention in a charging status. Wherein, a charging voltage of the charger is controlled by the control unit 24, and the battery 22 is charged by the charging voltage.
In conclusion, the battery assembly 2 and the electronic cigarette of the present invention employ the first charging electrode 31 mounted on the end cover 23, and the second charging electrode 32 mounted on a portion of the battery assembly 2 near an end of the end cover 23 and partially or wholly surrounding around the battery assembly 2. In the charging process, both the first charging electrode 31 and the second charging electrode 32 can be merely inserted in an external charger, so that charging operating time can be saved. Meanwhile, when the present invention is implemented in an electronic cigarette capable of being used for many times, the atomization assembly 1 does not need to be detached from the battery assembly 2 in the charging process. In this way, a defect that the atomization assembly 1 is prone to be lost when the atomization assembly 1 is detached from the battery assembly 2 is avoided.
