The present invention relates to a charging device, and more particularly to an open-ended magnetic attraction charging device for an electronic cigarette.
A conventional electronic cigarette is usually charged by disassembling the battery of the electronic cigarette and then plugging it into a cylindrical charging device for charging. The batteries of different sizes for electronic cigarettes need to be matched with different charging devices, resulting in poor applicability of the charging device for electronic cigarettes. The charging device of the conventional electronic cigarette is prone to overbalance when charging, which affects the user experience.
The internal structure of the charging device of the conventional electronic cigarette is poor to affect the stability of the overall structure of the charging device. In addition, the charging device is large in size, which is inconvenient for people to store and carry the charging device of the electronic cigarette. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
In view of the shortcomings of the prior art, the primary object of the present invention is to provide an open-ended magnetic attraction charging device for an electronic cigarette, which has an ingenious and reasonable structure, realizes an open-ended charging design, and can match electronic cigarette charging interfaces of different sizes, solves the problem that the charging device is prone to overbalance, and improves the user experience.
In order to achieve the above object, the present invention adopts the following technical solutions:
An open-ended magnetic attraction charging device for an electronic cigarette comprises a main body. A circuit board is disposed in the main body. The circuit board is connected with a power receiving end for connecting an external power source and a charging end for charging an electronic cigarette in a plane contact manner. The main body has a planar charging area for charging the electronic cigarette. The charging end is exposed to the planar charging area. The planar charging area is provided with a charging magnetic attraction area for attracting the electronic cigarette. A weight for increasing the weight of the charging device is disposed in the main body.
The present invention has obvious advantages and beneficial effects compared with the prior art. Specifically, it can be known from the above technical solutions:
The planar charging area provided on the main body can be applied to electronic cigarette charging interfaces of different sizes, thereby realizing an open-ended charging design and improving the applicability and versatility greatly. This is favorable for popularization and use. The charging magnetic attraction area provided in the planar charging area is provided with a magnetic positioning structure to facilitate the charging and positioning of the electronic cigarette. The weight provided in the main body is configured to increase the entire weight of the charging device. The center of gravity of the charging device can be flexibly adjusted by using the weight, thereby solving the problem that the charging device is prone to overbalance and improving the user experience.

The upper and lower ends of the curved circumferential wall 122 are connected to the upper surface of the top cover 12 and the bottom surface of the charging recess 121, respectively.
Preferably, the charging end 30 is a charging elastic needle that is telescopic to match the positioning of the electronic cigarette. Preferably, the underside of the bottom casing 11 is provided with a protective pad 300. The protective pad 300 is exposed to the underside of the bottom casing 11 for protecting the outer casing of the main body 10.
Preferably, the power receiving end is a power input data cable 50. The power input data cable 50 is electrically connected to the circuit board 20. In the first embodiment, one end of the power input data cable 50 is located inside the main body 10, and another end of the power input data cable 50 is located outside the main body 10.
In the first embodiment, the structure and arrangement of the circuit board 20 and the weight 40 are reasonable. Specifically, as shown in
Next, please refer to
The second embodiment is substantially similar to the first embodiment, and the main differences are: (1) the setting of the power input data cable; (2) the assembly of the top cover and the bottom casing, and the positioning of the weight. Next, the differences are described below.
(1) The power input data cable 50′ of the second embodiment is wound in the main body 10′.
