DETAILED DESCRIPTION OF THE EMBODIMENTS
A battery rod is provided in the application, and a hand feeling and a usage experience of an electronic cigarette may be improved with the battery rob. In addition, an electronic cigarette having the battery rod is provided.
The application is further described in detail in conjunction with drawings and embodiments, for making a solution of the application better understood by those skilled in the art.
Reference may be made to FIG. 1, which is a section view of an assembling structure of a battery rod according to an embodiment of the application.
In the embodiment, the battery rod provided in the present application is for being assembled with an atomizer to form an electronic cigarette. The battery rod includes a battery cartridge 11, and a connector 13 which is inserted at one end of battery cartridge 11 and connected with the atomizer. A battery 12 supplying power for the atomizer is provided in the battery cartridge 11. The battery cartridge 11 is a workpiece made of a non-metallic material. A connection cartridge 16 is inserted at one end of the battery cartridge 11 and is sleeved on the connector 13. The connection cartridge 16 and the battery 12 are coaxially arranged and are located at different positions in an axial direction of the battery rod. At a position corresponding to a position of the connector 13, a fastening ring 14 for clamping the connector 13 is sleeved on the outside of the connection cartridge 16. The battery cartridge 11 and the fastening ring 14 are coaxially arranged and are located at different positions in the axial direction of the battery rod. One end surface of the battery cartridge 11 faces one end surface of the fastening ring 14. During an operation process, the battery cartridge 11 made of the non-metallic material touches soft and comfortable, and a hand feeling of a cigarette may be well simulated, thereby greatly improving an overall simulation degree of the electronic cigarette and significantly improving the user experience.
Further, the two end surfaces of the battery cartridge 11 and the fastening ring 14 facing each other abut against each other, and an outer circumferencial surface of the battery cartridge 11 and an outer circumferencial surface of the fastening ring 14 are flush with each other. With the structure that the outer circumferencial surface of the battery cartridge 11 and the outer circumferencial surface of the fastening ring 14 are flush with each other, an outer structure of the electronic cigarette may be further optimized, an overall surface of the battery rod is flat and the battery rod is avoided from an uneven outer surface; accordingly, the user experience is further improved. In addition, a user is avoided from being hurt by the fastening ring during usage. Besides, outer surfaces of electronic cigarettes placed together may be closely abutted against each other; hence, scratchings between the electronic cigarettes, falling of electronic parts and oil leaking of the atomizer, which are caused by vibration when the electronic cigarettes are transported or are put in a pocket of a user, are avoided.
Further, a coating layer 15 is provided on the outer circumferencial surface of the battery cartridge 11 and the outer circumferencial surface of the fastening ring 14. The coating layer 15 may further ensure a flatness of an outer circumferencial surface of an assembling structure between the battery cartridge 11 and the connector 16, thereby further improving an overall outer structure of the electronic cigarette.
More specifically, the coating layer 15 is a paster. With a low procurement cost, a huge quantity of market supply, and an excellent bonding and fixation effect, the paster may meet assembling requirements of the electronic cigarette and the production cost of the electronic cigarette is effectively reduced. With the coated paster, the electronic cigarette having the battery rod further looks like the cigarette, thus improving the user experience. Furthermore, with the structure that the outer circumferencial surface of the battery cartridge 11 and the outer circumferencial surface of the fastening ring 14 are flush with each other, the service life of the battery rod coated by the paster may be lengthened since the paster is not easily scratched.
On another hand, the battery cartridge 11 is a workpiece made of a non-metallic material having a hardness smaller than that of copper. With the workpiece made of a soft material having a smaller harness, the whole hand feeling of the electronic cigarette may be further improved, and the user experience is better.
Furthermore, the battery cartridge 11 may be any one of a plastic workpiece, a rubber workpiece and a paper workpiece. Of course, the battery cartridge 11 is not restricted to the plastic workpiece, the rubber workpiece and the paper workpiece as long as practical usage requirements of the electronic cigarette may be satisfied.
Furthermore, one end of the battery cartridge 11 is provided with an end cap 17, the end being far away from the connector 13. The end cap 17 is provided with an air hole (not shown in the figure). An airflow passage 18 in communication with the air hole is formed between the battery 12 and the battery cartridge 11. The airflow passage 18 is for leading an airflow into the atomizer, the airflow is mixed with smoke in the atomizer and the mixture is inhaled into a mouth of a smoker.
Since the airflow passage 18 occupying a certain space is formed between the battery 12 and the battery cartridge 11, and the connection cartridge 16 and the battery 12 are coaxially arranged and are located at different positions in the axial direction of the battery rod, a thickness of a wall of the battery rod is small where the battery 12 is located. With the airflow passage 18, the battery cartridge 11 is elastically deformable; hence, the airflow is ensured with free passage and the hand feeling is better.
Further, the connector 13 includes a connection base 131, a holder 132 provided in the connection base 131, a lower electrode assembly 19 provided in the holder, and a spring leaf 133 fixed at the outside of the connection base 131 and abutting against an inner wall of the connection cartridge 16. The connection base 131 is provided with an atomizer groove 1311 for an insertion of the atomizer. The spring leaf 133 extends into the atomizer groove and elastically abuts against the atomizer. The lower electrode assembly 19 and the connection base 131 are respectively electrically connected to two electrodes of the battery 12 and are respectively for being electrically connected to the atomizer. Because the spring leaf 133 extends into the atomizer groove and elastically abuts against the atomizer, the reliability of a connection of the atomizer and the battery rod may be improved.
Further, the fastening ring 14 is a part made of a metallic material such as copper, iron, steel or the like, and the structure strength and tenacity of the metallic material are better than those of a non-metallic material; hence, it is ensured that the fastening ring 14 may not be torn easily during assembling. Therefore, with a cooperation of the fastening ring 14 made of the metallic material and the battery cartridge 11 made of the non-metallic material, advantages such as a steady and reliable battery rod structure, a high product yield, a small overall weight and a high similarity to the cigarette may be realized.
In an embodiment, an electronic cigarette provided in the application includes a battery rod and an atomizer which are connected to each other, and specifically, the battery rod is the battery rod described in the foregoing embodiment. The hand feeling and the user experience of the electronic cigarette and are good.
In conclusion, by arranging the battery rod and the electronic cigarette provided in the application into the above structure, the stability of the structure is enhanced and the connector is avoided from falling off from the battery rod. Since the battery cartridge and the fastening ring are coaxially arranged and the end surfaces of the battery cartridge and the fastening ring face each other, the overall surface of the battery rod is flat, and the user is protected from being hurt by the fastening ring during usage. Besides, with the above structure, outer surfaces of electronic cigarettes placed together may be closely abutted against each other; hence, scratchings between the electronic cigarettes, falling of electronic parts and oil leaking of the atomizer, which are caused by vibration when the electronic cigarettes are transported or are put in a pocket of the user, are avoided. During an operation process, the battery cartridge made of the non-metallic material touches soft and comfortable, and a hand feeling of a cigarette may be well simulated, thereby greatly improving an overall simulation degree of the electronic cigarette and significantly improving the user experience.
