[0060] The plug is connected with the input end of the second control module arranged in the second shell through a second wire laid in the sealing plug.

[0061] The initiation process is as follows: the first control module of the signal receiving mechanism is used to set the blast hole code through the code switch, then the corresponding electronic detonator initiation device is placed in the blast hole, and then the operator at the remote end sends the corresponding operation signal through the operation of the handset, the wireless detonator transmission controller is used to receive the operation signal transmitted by the handset and process the operation instruction, output the corresponding control instruction, the power amplifier amplifies the control instruction and inputs the amplified control instruction into the high-voltage capacitor resonator, the high-voltage capacitor resonator generates a high-voltage pulse signal after receiving the amplified control instruction, the transmitting coil generates a low-frequency electromagnetic field after receiving the pulse signal, and the corresponding control instruction is sent through the low-frequency electromagnetic field; at this time, the control instruction is a low-frequency electromagnetic wave instruction;

[0064] If the first capacitor has finished charging, a discharge command is received, the third switch is opened, the energy on the first capacitor is released, and the detonation operation is achieved.

[0065] Example 2 differs from Example 1 in that the quick connection mechanism includes a socket and a plug on the outer right side wall of the first housing.

[0067] When connecting two devices, insert the plug into the socket's hole. The conductive contacts make contact with the plug, forming an electrical connection. Then, by rotating the first housing (causing the socket to rotate as well), the external threads of the first housing and the internal threads of the second housing engage, completing the mechanical fixation. The connection is simple and quick: the plug and socket work together to quickly establish an electrical connection, and tightening the threads secures the connection. The entire process is simple and fast. The tight contact between the conductive contacts in the plug and socket ensures a stable electrical connection and reduces the risk of poor contact. The threaded connection ensures the two housings are firmly fixed together, preventing loosening due to vibration or other external forces during use.

[0068] Example 3, as shown in Figure 5, differs from Example 1 in that: the protective sleeves corresponding to each transmitting coil are arranged sequentially along the vertical direction, and the diameter of each protective sleeve increases sequentially along the vertical direction; the protective sleeves are fixedly connected by connecting rods; the protective sleeve includes two semi-circular protective sleeves 3, and the two semi-circular protective sleeves 3 are fixedly connected by hinges 4.

[0069] By securing protective sleeves of different diameters together using connecting rods, the overall structure of the device remains stable, even under vibration or external impact during operation. The semi-circular design of the protective sleeves and the hinged connection method increase the flexibility of individual sleeves while ensuring good closure.

[0070] The diameters of the protective sleeves increase in the vertical direction in turn, which helps to arrange multiple layers of coils in limited space, thereby reducing the overall footprint of the device. The gaps between the protective sleeves help air circulation, which can effectively help the coils dissipate heat and reduce the impact of heat accumulation on the performance of the device.
