[0002] Based on environmental protection requirements, many countries require that the batteries used in e-cigarettes be removable and recyclable; therefore, a tool is required to facilitate users to charge e-cigarette batteries. Figure 1 As shown in the figure, the positive and negative electrodes are at the same end of the battery); it is different from other existing general battery structures; therefore, existing charging equipment cannot be used. In addition, the specifications and models of batteries used in different electronic cigarettes are different; their diameters generally cover a variety of specifications such as 13, 14, 16 and 18 mm. How to meet the problem of recyclability of batteries of different specifications of electronic cigarettes is a problem that designers need to consider. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a multifunctional electronic cigarette battery charger, which can solve the charging problem of cylindrical positive and negative pole batteries with the same end of electronic cigarettes of different specifications.

[0004] The technical solution of the utility model to solve the above technical problems is:

[0005] The charger is generally block-shaped, and is provided with a plurality of charging seats matching the electronic cigarette batteries; the bottom of the charging seat is provided with positive and negative charging spring pins; the charger is provided with a TYPE-C interface; and also includes a PCBA board, and the TYPE-C interface is electrically connected to the charging spring pins of each charging seat through the PCBA board, so as to transmit power to the electronic cigarette battery connected to the charging spring pins.

[0006] The charger is in the shape of a cuboid; charging seats with diameters of 13, 14, 16, and 18 mm are arranged in a concave manner along the length direction.

[0007] A positive charging spring pin is arranged at the center of the bottom of the charging seat; a negative charging spring pin is arranged off the center; when a charged battery is inserted, the positive and negative charging spring pins respectively contact the positive and negative electrodes of the battery.

[0008] The charging seat is a cylindrical groove; elastic fixing silica gel is arranged along the peripheral edge; when the battery is inserted, an interference fit with the battery is achieved.

[0009] The PCBA board connects the positive charging spring pins and the negative charging spring pins of each charging seat in parallel.

[0010] The utility model is provided with 4 charging holes on a charger, which can charge electronic cigarette batteries with diameters of 13mm, 14mm, 16mm and 18mm respectively. Of course, if necessary, more holes can be designed to meet the charging needs of batteries with more diameters. A charging spring pin is designed inside the charger. When the cylindrical positive and negative poles of the same-end battery are inserted into the corresponding holes, the positive and negative poles of the battery contact the spring pin to achieve charging. The battery is inserted into the charging seat and the ribs that fix the silicone are interference fit with the battery, so that the battery and the spring pin are always in contact, ensuring the reliability of charging. Compared with chargers on the market, the charger of the utility model is more convenient to charge, and only requires one action of inserting the battery; and it can accommodate the charging of batteries of various lengths without being restricted by the length of the battery.

[0019] The following embodiments are descriptions of specific implementation methods of the present invention. Such descriptions are intended to facilitate the understanding of the technical solutions of the present application by those skilled in the art, and are not intended to limit the protection scope of the technical solutions of the present invention. All equivalent transformations that can be obtained according to the descriptions of the embodiments of the present invention should be within the protection scope of the present invention.

[0020] like Figure 2-7 As shown, the charger 2 of the electronic cigarette battery 1 of the utility model is in the shape of a cuboid; charging seats 21 with diameters of 13, 14, 16, and 18 mm are arranged in a concave arrangement along the length direction. Of course, according to actual needs, more diameter specifications or more charging seats 21 can be designed to meet the charging needs of more batteries 1.
