Charging verification device with airtight confirmation structure

The invention discloses a charging verification device with an airtight confirmation structure, and relates to the field of charging verification devices. An existing portable charging verification device lacks an airtight confirmation structure in the process of connecting equipment with a charging gun and a charging station, and charging verification is carried out when plugging of the charging gun is loosened, so that great potential safety hazards are brought. The device comprises a control circuit board, a communication circuit board, a charging terminal assembly, a locking mechanism, a sensor group and a shell, the control circuit board is connected with the communication circuit board, the sensor group is connected with the control circuit board, and sensing heads of the sensor group are connected to a female end of the charging terminal assembly and make contact with a charging gun when the charging gun is inserted. When the plugging of the charging gun is loosened, the sensor returns an abnormal sign
