[0006] As a preferred embodiment of this utility model, an electrode sheet is attached to the outer surface of the electrode module, and a transmission line is fixedly installed on one side of the electrode sheet.

[0007] As a preferred embodiment of this utility model, straps are fixedly installed on both sides of the bottom of the EEG cap body.

[0008] As a preferred technical solution of this utility model, a connecting groove is provided on one side of the outer surface of the EEG cap body, and the connecting groove is connected to the fixing base.

[0009] In a preferred embodiment of this invention, the connecting groove is connected to the sleeve.

[0010] As a preferred embodiment of this utility model, a connecting wire is fixedly installed inside the connecting groove.

[0011] As a preferred embodiment of this invention, the end of the connecting wire can be plugged into and connected to the electrode module.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This electrode module replacement structure, through the replacement structure and electrode sheet, allows for rapid replacement of the electrode module by disconnecting the electrode module from the connecting wire, removing the original electrode module, connecting the new electrode module to the connecting wire, and inserting it into the sleeve. Pressing the electrode module inward causes the spring to contract, moving the lever to the opening of the slide groove. Since the collar is fitted on the outer surface of the electrode module, rotating the lever moves it to the side of the slide groove. Then, rotating the handle rotates the threaded rod, causing the threaded block to move horizontally upward on its outer surface. This causes the fixing pin to move upward and be inserted into the hole of the lever for fixation, thus completing the replacement of the electrode module. This achieves the purpose of rapid electrode module replacement and improves the maintenance efficiency of the device. Attached Figure Description

The replacement structure 4 includes a sleeve 41 and a side block 42. A fixing ring 43 is fixedly installed inside the sleeve 41, a spring 44 is fixedly installed on one side of the outer surface of the fixing ring 43, an electrode module 45 is placed inside the sleeve 41, a collar 46 is sleeved on the outer surface of the electrode module 45, a lever 47 is fixedly installed on one side of the collar 46, a groove 48 is opened on one side of the outer surface of the sleeve 41, a threaded rod 49 is rotatably installed inside the side block 42, a handle 410 is fixedly installed at the end of the threaded rod 49, a threaded block 411 is threadedly installed on the outer surface of the threaded rod 49, and a fixing pin 412 is fixedly installed on one side of the outer surface of the threaded block 411.

[0022] Please see Figure 1-3 An electrode sheet 5 is attached to the outer surface of the electrode module 45, and a transmission line 51 is fixedly installed on one side of the electrode sheet 5.

[0023] After the electrode module 45 is fixed, the electrode sheet 5 can be attached to the surface of the electrode module 45 to conduct electricity. It can be connected to other components through the transmission line 51.

[0024] Please see Figure 1-5 The bottom of the EEG cap body 1 is fixedly fitted with straps 2 on both sides. A connecting groove 6 is formed on one side of the outer surface of the EEG cap body 1, and the connecting groove 6 communicates with the fixing base 3. The connecting groove 6 communicates with the sleeve 41. A connecting wire 61 is fixedly installed inside the connecting groove 6.
