Description

Technical Field

[0001] The utility model relates to the field of lithium battery mobile power supplies, in particular to a lithium battery mobile power supply. Background Art

[0002] A mobile power bank is a portable charger that combines power supply and charging functions. It generally uses lithium batteries as power storage units. It is easy and quick to use and can charge mobile phones, tablets and other digital devices anytime and anywhere.

[0003] Chinese patent publication number CN211351769U discloses a lithium battery mobile power supply comprising a protective housing, a connecting block, and a charging housing. The bottoms of both ends of the protective housing are provided with fixed slots, and the tops of both ends of the protective housing are provided with slides. The slides are each mounted with connecting blocks via sliders. Telescopic springs are evenly mounted in the middle of the bottom of the protective housing, and the charging housing is mounted on top of the telescopic springs. During use, the heat generated by the lithium battery is transferred to the charging housing, where it is dissipated through heat dissipation holes. The charging housing is not in direct contact with the protective housing, making it difficult for heat from the charging housing to be directly transferred to the protective housing. After heat is dissipated through the heat dissipation holes, only a small amount of heat is transferred to the protective housing, preventing the protective housing from being heated to a high temperature. This reduces discomfort in the user's hand when holding the device.

[0004] During actual use of the mobile power supply of the above patent, the heat generated by the mobile power supply is naturally dissipated through the heat dissipation holes. However, when the mobile power supply is used in a relatively cold environment, the heat generated by itself is relatively precious and cannot be well utilized. Utility Model Content

When the lithium battery itself generates heat, the fan can be turned on to draw external air into the protective shell to dissipate heat for the lithium battery. The temperature of the air rises after being heated by the lithium battery. At this time, the cover is opened and hot air is ejected from the heat dissipation hole. The user can use it to keep warm and reasonably utilize the heat generated by the lithium battery itself, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a lithium battery mobile power supply, comprising a protective shell, a fan is provided on the protective shell, a connecting plate is provided on one end of the fan extending into the protective shell, and also comprising a concentrated air outlet duct, the concentrated air outlet duct is provided on the connecting plate, a fixed block is provided on the protective shell, a damping rotating shaft is provided on the fixed block, a cover plate is provided on the movable end of the damping rotating shaft, a heat dissipation hole is provided on the fixed block, a lithium battery is provided in the protective shell, and an air inlet is provided on the end of the fan away from the concentrated air outlet duct.
