Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0029] Please refer to Figures 1-6 As shown, an electronic cigarette with bottom charging in this embodiment includes an atomizer 1, an outer shell 2, a battery cell 3, and a control board 4. The atomizer 1 is installed on the outer shell 2, the battery cell 3 and the control board 4 are installed inside the outer shell 2. An airflow induction control component (not shown in the figure) and a charging interface 41 are connected to the control board 4. A bottom cover 5 is provided at the bottom of the outer shell; the bottom cover 5 is preferably made of metal, and the outer shell 2 and the bottom cover 5 can be fixed by means of adhesive bonding, snap connection or tightly fitting socket connection. The outer shell 2 is preferably made of metal, and the bottom cover 5 and the outer shell 2 can be socketed by means of a tight fit.

[0030] The charging interface of the present invention can be a Type-C interface, or a USB-C interface, or a USB interface, or a Lightning interface, etc. The illustration in this embodiment provides a reference with a Type-C interface as an example.

[0031] Please refer to Figure 2 As shown, a hole position 51 for installing the charging interface is provided at the bottom of the bottom cover 5, and a reverse slot 52 is provided on the inner wall of the bottom cover 5.

[0032] Please refer to Figures 3-6As shown, a base bracket 6 is sleeved inside the bottom cover 5. The base bracket 6 includes a bottom plate 60, and a first support wall 61 and a second support wall 62 that sequentially extend upward along the bottom plate 60. The bottom plate 60 and the first support wall 61 are sleeved inside the bottom cover 5, and the second support wall 62 is exposed above the bottom cover 5. A charging interface hole 601 corresponding to the hole position 51 is formed on the surface of the bottom plate 60.

[0033] In this embodiment, a protruding rib 602 is provided at the edge of the charging interface hole 601. The rib 602 is used for installing and limiting the charging interface 41. The two sides of the rib 602 close to the first support wall 61 are connected to the first support wall 61. Support columns 6021 extending upward are provided on the two sides where the rib 602 is connected to the first support wall 61. The support columns 6021 are used for supporting the control board 4.

[0034] In this embodiment, an anti-insertion wall 611 protruding outward is provided on the outer wall of the first support wall 61. The anti-insertion wall 611 can be inserted into the anti-insertion slot 52 to fix the first support wall 61 to the bottom cover 5. A set of inwardly protruding and oppositely arranged buckle walls 621 are provided on the inner wall of the second support wall 62. The buckle walls 621 are used for fastening the top of the control board 4.

[0035] Preferably, support arms 613 protruding outward are provided on the front and back sides of the buckle wall 621. The support arms 613 can promote the inward deformation of the buckle wall 621 under external force extrusion, making the fixation of the buckle wall 621 to the control board 4 more stable and reliable.

[0036] Preferably, an LED lamp (not shown in the figure) is provided on the control board 4. The LED lamp is used to provide bottom lighting support when the charging interface is conducting electricity.

[0037] Preferably, the second support walls 62 are a set of 4 and are equally spaced at the top of the first support wall 61.

[0038] Preferably, the base bracket 6 includes four such ribs 602. A hollow structure is formed between the ribs. Through holes 603 are formed on the surface of the bottom plate 60. The through holes 603 are symmetrically distributed on both sides of the ribs 602. The above structure is beneficial to the smooth flow of the e-cigarette airflow at the bottom and can also provide support for guiding light for the bottom charging interface 41.

[0039] Preferably, a set of oppositely arranged positioning grooves 53 are provided at the top of the bottom cover 5. The positioning grooves 53 are used for positioning when the base bracket 6 is installed, making the installation more convenient.

[0040] When the utility model is installed, the reverse insertion wall 611 is inserted into the reverse insertion slot 52 from the positioning slot 53, and then the base bracket 6 can be fixed in the bottom cover 5. One end of the charging interface of the control board 4 is installed in the bone position 602, and the end of the control board 4 far from the charging interface 41 is snap-connected with the snap wall 621. The support column 6021 limits the other side of the control board 4, and then the installation of the control board 4 and the base bracket 6 can be completed. The control board 4 is clamped from above by the snap wall 621 and supported from below by the support column 6021, which can prevent the control board 4 from loosening and enhance the connection stability of the control board 4. Finally, the bottom cover 5 and the outer shell 2 are installed and fixed, and the installation of the whole machine can be easily completed. The installation process is simple and fast, and the maintenance and replacement are convenient.
