Lithium battery charging device capable of automatically controlling temperature of mobile phone to be powered off for fire prevention during charging

Abstract

The invention relates to the technical field of lithium battery charging and discloses a lithium battery charging device capable of automatically controlling the temperature of a mobile phone to be powered off for fire prevention during charging. The device comprises a charging bin, the interior of the charging bin is movably connected with a fixed rail; the interior of the charging bin is movablyconnected with a placement plate; a fireproof bin is movably connected to the bottom of the interior of the charging bin, a fireproof rail is movably connected to the upper portion of the fireproof bin, an air pressure bin is movably connected to the bottom of the interior of the charging bin, an air outlet pipe is movably connected to the left side of the air pressure bin, and a pressure rail ismovably connected to the left side of the interior of the charging bin. A compression pressure spring is moved leftwards, so that air in the air outlet pipe enters the matched air pressure rail, an air pressure sliding block is quickly pushed to move leftwards, a data head is further driven to move leftwards, and charging is cut off, so that the effect of preparing for cutting off a power supplyat any time through the temperature of the battery to prevent the battery from being damaged during charging is achieved.

Description

technical field [0001] The invention relates to the technical field of lithium battery charging, and specifically relates to a lithium battery charging device for automatically controlling the temperature of a mobile phone during power failure and fire prevention during charging. Background technique [0002] Lithium battery is a kind of battery made of lithium alloy or lithium metal and using non-aqueous electrolyte solution. As early as 1912, lithium metal battery was proposed and began to be studied. It was not until the 1970s that lithium batteries were really studied. Due to the very active chemical properties of lithium metal, the processing, production and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream of batteries. [0003] The lithium battery appliances we use daily, such as mobile phones, often face the problem that they will not be automatically disconnect...
