[0030] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present application and with reference to the accompanying drawings.

[0031] As Figure 1 shown, a portable transcutaneous auricular vagus nerve electrical stimulation device includes: a main body 1, a pair of flexible legs 2, a pair of ear stimulation devices 3 and a stimulation generating device;

[0032] The main body 1 is an arc-shaped hollow structure with an opening on one side. The stimulation generating device is arranged in the inner cavity of the main body 1. At both ends of the opening of the main body 1, flexible legs 2 are sleeved respectively. The inside of the flexible legs 2 is hollow and communicated with the inner cavity of the main body 1. The ear stimulation device 3 is electrically connected with a connecting wire 4. After the connecting wire 4 passes through the side wall of the flexible leg 2, it is electrically connected with the stimulation generating device.

[0033] On the inner side wall of the main body 1, a sliding groove 102 is formed. Two sliding blocks 101 are slidably connected to the sliding groove 102. The two sliding blocks 101 extend into the inner cavity of the main body 1 and are respectively fixedly connected to the middle part of the connecting wire 4. Sliding the sliding blocks 101 is used to stretch and contract the connecting wire 4.

[0034] In a specific embodiment, the main body 1 is made of a plastic material with relatively high hardness, which is convenient for the sliding block 101 to slide on the main body 1 and for arranging the stimulation generating device in the main body 1. The flexible leg 2 is made of a memory flexible material with a plasticizable curvature, which is convenient for the user to change the shape of the flexible leg 2, so as to adapt to different users and improve the wearing comfort of the device. Preferably, the surfaces of the main body 1 and the flexible leg 2 are coated with a rubber coating to avoid discomfort to the user during wearing and further improve the wearing comfort.

[0035] As Figure 1 shown, a hanging ear 5 is arranged on the circumferential outer wall of the ear stimulation device 3.

[0036] Through the setting of the hanging ear 5, the force on the ear can be further relieved, and the supporting force of the ear on the ear stimulation device 3 can be dispersed by increasing the force application points, so as to avoid discomfort caused by long-term force on some positions of the user's ear. Preferably, the hanging ear 5 is also made of a memory flexible material with a plasticizable curvature, which is convenient for adjusting the shape and curvature.

[0037] As Figure 2 shown, the ear stimulation device 3 includes: a headphone main body. One end of the headphone main body is sequentially fixedly connected with a first boss 301 and a second boss 302, and the diameters are sequentially reduced. The side wall of the headphone main body is connected with one end of the connecting wire 4.

[0038] On the circumferential side wall of the first boss 301, a flexible connecting rod 305 is arranged. One end of the flexible connecting rod 305 away from the first boss 301 is provided with a second conductive silica gel 304.

[0039] One end of the second boss 302 away from the first boss 301 is provided with a first conductive silica gel 303. The first conductive silica gel 303 and the second conductive silica gel 304 are respectively electrically connected with the connecting wire 4.

[0040] The provision of the flexible connecting rod 305 facilitates the user to adjust the stimulation point. Preferably, the flexible connecting rod 305 is also made of a memory flexible material with a plasticizable arc, which is convenient for adjusting the shape and has a certain supporting force at the same time, so that the end fitting can always fit the stimulation point.

[0041] As Figure 2-3 shown, a first electrode 306 is provided at the end of the second boss 302, and the first conductive silicone 303 is nested on the first electrode 306; a second electrode 310 is provided at one end of the flexible connecting rod 305 away from the first boss 301, and the second conductive silicone 304 is nested on the second electrode 310; the first electrode 306 and the second electrode 310 are respectively electrically connected to the connecting wire 4.

[0042] As Figure 3 shown, a first wire 401 and a second wire 402 are provided inside the connecting wire 4. The first wire 401 is used to connect the first electrode 306 and the stimulation generating device, and the second wire 402 is used to connect the second electrode 310 and the stimulation generating device.

[0043] Through the nested arrangement of the first conductive silicone 303 and the second conductive silicone 304, it is convenient for the user to replace according to actual usage requirements, such as replacing conductive silicones of different sizes and shapes to obtain better stimulation effects and experiences, and timely replacement can also ensure the cleanliness of the conductive silicone.

[0044] As Figure 3 shown, a plug 307 is provided at one end of the flexible connecting rod 305 adjacent to the first boss 301. A jack cooperating with the plug 307 is provided on the circumferential side wall of the first boss 301. A spring piece 308 is provided in the inner cavity of the jack. A connecting rod wire 309 is provided inside the flexible connecting rod 305. The connecting rod wire 309 is used to connect the plug 307 and the second electrode 310;

[0045] The spring piece 308 is connected to the second wire 402.

[0046] Through the plug-in arrangement of the flexible connecting rod 305, it is convenient to quickly replace the flexible connecting rod 305 in case of fatigue fracture during long-term use, avoiding the scrapping of the entire stimulation device due to local damage. During the use of the flexible connecting rod 305, frequent bending adjustment is likely to affect its supporting force and stability, and fatigue fracture may occur. Therefore, the plug-in structure is provided to facilitate its flexible replacement.

[0047] As Figure 4As shown, the stimulation generating device includes: a controller, a power supply module, a pulse generator, and a wireless communication module. The power supply module, the pulse generator, and the wireless communication module are electrically connected to the controller respectively. The pulse generator is electrically connected to two ear stimulation devices 3 through a connecting wire 4.

[0048] The wireless communication module is used to receive control signals from an external device and transmit them to the controller. The controller selects a corresponding stimulation mode according to the received control signals, and controls the pulse generator to emit corresponding stimulation signals. The stimulation signals are transmitted to the ear stimulation device 3 through the connecting wire 4 to stimulate the ear stimulation points of the user. The power supply module is used to provide power for the entire device.

[0049] As Figure 1 shown, a storage groove 201 is formed on the outer side wall of the flexible leg 2. The storage groove 201 is used to store the ear stimulation device 3.

[0050] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the creative concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
