[0037] An electrode body 200 is fixedly provided on the upper top wall of the earplug body 100, and an elastic clip 300 is provided above the earplug body 100. One end of the electrode body 200 away from the earplug body 100 is fixedly provided on the inner side wall of the elastic clip 300. The elastic clip 300 is used to place the user's ear.
[0038] Magnetic components are respectively provided on the electrode body 200 and the elastic clip 300. The magnetic components are used to attach the elastic clip 300 to the user's ear.
[0039] In this embodiment, the auricular vagus nerve electrical stimulation interface device includes an earplug body 100, an electrode body 200, an elastic clip 300, and a magnetic attraction assembly. The electrode body 200 is fixedly mounted on the upper top wall of the earplug body 100, and the elastic clip 300 is also located above the earplug body 100. One end of the electrode body 200 away from the earplug body 100 is fixedly mounted on the inner side wall of the elastic clip 300, thereby fixing the relative positions of the electrode body 200, the elastic clip 300, and the earplug body 100. During use, the user's ear is placed inside the elastic clip 300, and the elastic clip 300 is attracted and held to the user's ear by the magnetic attraction assembly respectively located on the electrode body 200 and the elastic clip 300, so as to ensure that the elastic clip 300 will not fall off due to movement or sweating during use, which can effectively improve the consistency of treatment.
[0040] According to one embodiment provided by this utility model, such as Figure 2 and Figure 3 As shown, the magnetic attraction assembly includes a first magnet 201 and a second magnet 301;
[0041] The electrode body 200 has a first groove in the middle, and the first magnet 201 is disposed in the first groove.

The electrode patch 204 is double-fixed by the electrode adhesive patch 206 and the magnetic suction patch 205, which can prevent the electrode patch 204 from shifting or falling off during the treatment process, so as to ensure the continuity of the treatment.
[0052] According to one embodiment provided by this utility model, such as Figure 1 As shown, an ear canal conductor 101 is fixed on the side of the earplug body 100 facing the user's ear.
[0053] In this embodiment, the earplug body 100 is fixedly provided with an ear canal conductor 101 on the side facing the user's ear. This ensures that when the earplug is worn, it is inserted into the user's ear canal through the ear canal conductor 101, which restricts the relative position of the earplug body 100 and ensures that the electrode body 200 can be located in the user's concha and fit the user's concha.
