Referring to fig. 1, fig. 2 and fig. 3, an electronic cigarette according to an embodiment of the present invention includes a battery assembly 100 and an atomizing assembly (not shown) coupled to an end of the battery assembly 100. Battery assembly 100 is used to power the atomizing assembly. The atomization assembly is used for storing atomized liquid and heating the atomized liquid under the electric drive of the battery assembly 100, so that the atomized liquid is atomized to form smoke for a user to suck. It should be noted that the structure of the atomizing assembly is substantially the same as that of the atomizing assembly in the prior art, and therefore, the description thereof is omitted.

The battery assembly 100 includes a battery holder 10 and a sealing sleeve 20. The battery holder 10 is used for mounting a battery cell (not shown) and a microphone (not shown) electrically connected with the battery cell. One side of the battery bracket 10 is provided with a card slot 11 (see fig. 2 and 3), and a bottom wall 110 of the card slot 11 is provided with a mounting hole 15 for mounting a microphone and an airflow groove 16 communicated with the mounting hole 15. When a user inhales, airflow in the airflow groove 16 is sucked out to form negative pressure, and the microphone immediately detects the negative pressure, so that the electric core is controlled to supply power to the atomization assembly.

The sealing boot 20 includes a sealing cover 21 and an extension 23 connected to the sealing cover 21 and extending along one side thereof. The sealing cover 21 covers one end of the battery holder 10 and presses against the sealing cover 21 of the sealing sleeve when the atomization assembly is coupled to the end of the battery holder 10 where the sealing cover 21 is disposed, so as to seal a gap between the battery holder 10 and the atomization assembly. The extension portion 23 is disposed in the card slot 11 and is used for sealing the mounting hole 15 of the microphone and the airflow slot 16 so as to form an airflow channel.

At least one first positioning column 12 is convexly arranged on the bottom wall 110 of the card slot 11, the extending portion 23 is provided with first positioning holes 24 corresponding to the first positioning columns 12 one by one, and the first positioning columns 12 penetrate through the corresponding first positioning holes 24. So, the sealed lid 21 cover of seal cover 20 is located the one end of battery holder 10, and extension 23 is positioned in draw-in groove 11 through the cooperation of first reference column 12 with first locating hole 24 for sealed lid 21 and extension 23 are fixed more stable with battery holder 10, can be better laminate mutually with battery holder 10, guarantee sealed effect, be favorable to guaranteeing the inspection sensitivity of miaow head, and it is little to avoid appearing the cigarette volume, the hard phenomenon of suction.

In particular embodiments, the first positioning column 12 includes two. The two first positioning posts 12 are respectively located at two opposite sides of the mounting hole 15, so that the extension portion 23 can be better positioned. It is understood that the first positioning holes 24 also include two, and the two first positioning holes 24 correspond to the two first positioning posts 12 one to one. Further, the two positioning posts are symmetrically arranged relative to the mounting hole 15.

In the embodiment of the present invention, at least one second positioning column 13 is disposed on the end surface of the battery holder 10 covered with the sealing cover 21. The sealing cover 21 is provided with second positioning holes 26 (see fig. 3) corresponding to the second positioning posts 13 one to one. The second positioning posts 13 are inserted into the corresponding second positioning holes 26, so as to position and fix the sealing cover 21, and further improve the connection stability between the sealing cover 21 and the battery holder 10.

In an embodiment, a flange portion 132 (see fig. 2) is protruded from an end of the second positioning column 13 away from the battery holder 10. When the second positioning posts 13 are inserted into the corresponding second positioning holes 26, the flange portion 132 abuts against a side of the sealing cover 21 away from the battery holder 10. Thus, the flange 132 effectively prevents the sealing cover 21 from coming off the second positioning column 13, and compresses the sealing cover 21, so that the sealing cover 21 is tightly attached to the battery holder 10.

In some embodiments, the second positioning holes 26 include two, and the two second positioning holes 26 are located at two longitudinal ends of the sealing cover 21. Correspondingly, the number of the second positioning posts 13 is also two, and the two second positioning posts 13 correspond to the two second positioning holes 26 one by one. In this way, the fixing stability of the seal cover 21 and the battery holder 10 is further improved.

In one embodiment, the battery holder 10 further includes an output electrode (not shown). The battery holder 10 is provided with an electrode mounting hole 17 at one end thereof covered with a sealing cover 21. The output electrode is fixedly mounted in the battery mounting hole 17. The sealing cap 21 has a through slot 27 through which the output electrode passes out, so that the output electrode can be electrically connected with the atomization assembly when the atomization assembly is mated with the end of the battery assembly 100 having the sealing sleeve 20, thereby outputting electric energy for the atomization assembly. It will be understood that the output electrode includes two (i.e., a positive electrode and a negative electrode), and thus, the battery holder 10 is provided with two electrode mounting holes 17 at the end thereof covered with the sealing cap 21, for respectively mounting the two output electrodes.

Further, the through groove 27 is located between the two second positioning holes 26, and penetrates through the two second positioning holes 26. Thus, on one hand, the output electrode can be ensured to penetrate out of the through groove 27; on the other hand, the material is saved, and the light weight of the electronic cigarette is facilitated.

In an embodiment, each second positioning column 13 has a mounting cavity 132, and a magnetic member (not shown) is mounted in the mounting cavity 132, and the magnetic member is used for attracting a magnet on the atomizing assembly, so that the atomizing assembly is coupled to the battery holder 10 of the battery assembly 100.
