1. A smart key label, wherein the smart key label comprises a sliding push sleeve (101), a cone guide body (103) connected with the sliding push sleeve (101) through an actuator (108), a sealing ring (102) mounted on a right end of the sliding push sleeve (101), and an inner end surface of the sealing ring (102) is attached to an outer end surface of the cone guide body (103); the actuator (108) is connected with the sliding push sleeve (101) through a thread, and a blocking portion (104) is connected to an internal right end of the cone guide body (103); the cone guide body (103), the blocking portion (104) and the actuator (108) form a sealing cavity; a position detection sensor (105), a control circuit board (106) and a high temperature battery (107) are arranged in the sealing cavity and are connected by a wire; the actuator (108) is capable of driving the sliding push sleeve (101) to move relative to the cone guide body (103); the sliding push sleeve (101) drives the sealing ring (102) to move relative to the cone guide body (103) to expand or contract the sealing ring (102);
a flowback channel is formed in a left part of the sliding push sleeve (101), and a soluble ball (109) is arranged on one end of the flowback channel, which is capable of blocking a part nearing the end of the flowback channel.
