8. A method for using a lithium battery charging temperature detection device, which is realized based on the lithium battery charging temperature detection device of claim 7, is characterized by comprising the following steps:
the method comprises the following steps: the hinged box door (37) is opened, the baffle (35) is rotated, the lithium battery to be charged is placed in the detection box (1), then the charging head (17) is electrically connected with the charging port of the lithium battery, and then the charging head (17) is electrically connected with an external power supply to charge the lithium battery;
step two: during the charging of the lithium battery, the second temperature sensor (18) senses the temperature change of the connecting position of the charging head (17) and the lithium battery, the first temperature sensor (9) senses the temperature change of the body of the lithium battery, and the second temperature sensor (18) and the first temperature sensor (9) convert temperature signals into electric signals and transmit the electric signals to the control circuit board (10);
step three: the output end of the driving motor (38) drives the driving rotating rod (19) and the chain wheel (20) to rotate, the chain wheel (20) drives the chain (21) to rotate, the limiting mounting plate (24) and the limiting block (25) rotate along with the chain (21), and during the rotation of the chain (21), the limiting block (25) is attached to the limiting head (33) on one side and drives the connecting bottom plate (28) to move from the front end to the rear end of the guide clamping groove (26) by pushing the limiting head (33) on one side;
step four: when the connecting bottom plate (28) drives the adjusting block (31) to move to the rear side of the adjusting head (23) at the rear side, the adjusting head (23) extrudes the adjusting block (31) to move towards one side, the adjusting block (31) drives the sliding rod (30) and the moving block (32) to move, the moving block (32) extrudes the return spring (34) to contract and drives the limiting head (33) to move at the same time, the contact between the limiting block (25) and the limiting head (33) is relieved, the limiting block (25) and the limiting head (33) at the other side are contacted with each other along with the continuous rotation of the chain (21), the connecting bottom plate (28) is pushed to move forwards from the back in the guide clamping groove (26), then the adjusting block (31) at the other side and the adjusting head (23) at the front side are extruded with each other, and the contact between the limiting block (25) and the limiting head (33) is relieved;
step five: the connecting bottom plate (28) reciprocates in the guide clamping groove (26) through the guide sliding block (27), the connecting bottom plate (28) drives the detection mounting plate (8) and the first temperature sensor (9) to move back and forth in the detection box (1) through the sliding sleeve (5), and therefore temperature detection is carried out on a battery body of the lithium battery;
step six: when the temperature of a charging head (17) or a battery body of a lithium battery is too high, the control circuit board (10) receives signals of a first temperature sensor (9) and a second temperature sensor (18), the heat dissipation fan (12) is controlled to be started immediately, the heat dissipation fan (12) accelerates air circulation of the inner wall of the detection box (1), and the exchange of cold and hot air on the surface of the lithium battery is accelerated.
