Description

Technical Field

[0001] The utility model relates to the field of portable chargers, in particular to a portable charger with an anti-drop function. Background Art

[0002] With the popularity of mobile devices and the increasing frequency of use, portable chargers have become an indispensable accessory in people's daily lives. However, in daily use, portable charger sockets are mostly embedded in the wall. Due to long-term use of the socket, the internal screws of the socket are loose or the spring sheet is damaged, resulting in the plug being loose when the charger is used, poor contact, intermittent charging, or requiring manual straightening to maintain the connection, or because the charger is too heavy, causing the charger plug to loosen. For this reason, we propose a portable charger with an anti-drop function.

[0003] Existing technologies for increasing the anti-drop function of portable chargers include adding magnetic suction plates or adding shock-absorbing reinforcement functions. In addition, there are anti-drop portable chargers that can add a hidden suction cup structure. The suction cup structure is tightened by the difference between the internal and external air pressures. The existing suction cup structure only considers tightening, and has not yet considered adjusting the air pressure inside the suction cup. The purpose of the utility model is to adjust the internal air pressure of the suction cup through a pipeline to achieve a close fit between the portable charger and the socket to ensure good charging.
