Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] A transcutaneous electrical stimulation device for auricular acupoints, the structure of which can be Figure 1-Figure 5 As shown in the figure, in this embodiment, the transcutaneous electrical stimulation device for ear acupoints includes: a fixing belt, an electrical stimulation unit and a controller 2, and the controller 2 and the electrical stimulation unit are respectively arranged on both sides of the fixing belt. When using it, the user can wear the device on the head through the fixing belt, and make the side of the fixing belt with the electrical stimulation unit fit the head, then start the controller 2, and use the microcurrent generated by the controller 2 to perform transcutaneous electrical stimulation on the ear acupoints to achieve a therapeutic effect.

[0036] Specifically, the electrical stimulation unit in this embodiment includes a Yintang stimulation component and two ear stimulation components, and the two ear stimulation components are arranged in a mirror image on both sides of the Yintang stimulation component. After wearing, the Yintang stimulation component will be aligned with the Yintang area of ​​the user's head, and the two ear stimulation components will be aligned with the two ears of the user respectively.

[0037] The Yintang stimulation component includes a Yintang cover 31 and a hydrogel electrode sheet 32, wherein the Yintang cover 31 is provided with a mounting groove, and the hydrogel electrode sheet 32 ​​is detachably arranged inside the mounting groove. A first conductive contact electrically connected to the controller 2 is also provided inside the mounting groove. When the hydrogel electrode sheet 32 ​​is loaded into the mounting groove, the first conductive contact will contact the hydrogel electrode sheet 32, so that the microcurrent generated by the controller 2 is transmitted to the inside of the hydrogel electrode sheet 32, and finally acts on the Yintang area of ​​the user's head through the hydrogel electrode sheet 32. In addition, since the hydrogel electrode sheet 32 ​​is connected to the Yintang cover 31 in a detachable manner, after the device is used for a period of time, the user can disassemble and replace the hydrogel electrode sheet 32 ​​to ensure that the hydrogel electrode sheet 32 ​​has good conductivity.

[0038] The ear stimulation component includes an earmuff 41 and a plurality of second conductive contacts 43, wherein the earmuff 41 is provided with a receiving groove 42, and the plurality of second conductive contacts 43 are all arranged inside the receiving groove 42, and each second conductive contact 43 is electrically connected to the controller 2. When the user finishes wearing the device, the user's ear will enter the receiving groove 42 on the earmuff 41, and at this time, the second conductive contact 43 will contact the area where the acupuncture points on the user's ear are located, so that the microcurrent generated by the controller 2 acts on the user's ear acupuncture points, achieving the purpose of transcutaneous electrical stimulation of the ear acupuncture points.

[0039] Optionally, in order to enhance the transcutaneous electrical stimulation effect of the auricular acupoints of the device, three second conductive contacts 43 may be provided inside the receiving slot 42 of each earmuff 41 in the present embodiment, and the three second conductive contacts 43 are respectively a Shenmen acupoint contact, a Jiaogan acupoint contact and a Xin acupoint contact. When the user's ear enters the receiving slot 42, the Shenmen acupoint contact, the Jiaogan acupoint contact and the Xin acupoint contact will contact the user's Shenmen acupoint, Jiaogan acupoint and Xin acupoint respectively, so that the microcurrent acts accurately on the above acupoints.

[0040] In addition, since the ear sizes of different users vary, the positions of the ear acupoints may vary slightly. To ensure that the second conductive contact 43 accurately contacts the user's ear acupoints, the second conductive contact 43 may be set to a hemispherical protrusion structure, thereby increasing the surface area of ​​the second conductive contact 43 and increasing the contact probability of the second conductive contact 43 with the user's ear acupoints.

[0041] It should be noted that the controller 2 described in this embodiment can be a common EMS microcurrent generating device in the prior art. When the controller 2 is started, the EMS microcurrent generated by the controller 2 can be transmitted through a wire (the wire in the device can be external to the outside of the fixing belt, or built-in to the inside of the fixing belt) to the first conductive contact and the second conductive contact 43, so that the device has a transcutaneous electrical stimulation effect. The internal structure, working principle and use method of the EMS microcurrent generating device are already well known to those skilled in the art, and the EMS microcurrent generating device itself does not belong to the invention point of the utility model, so the relevant content is not repeated in this application document.

[0042] As an optional implementation of this embodiment, in order to facilitate the storage of the device, Figure 5 As shown, the controller 2 may be provided with a first snap buckle 21, and the fixing belt should be provided with a second snap buckle 22 that matches the first snap buckle 21. When the device needs to be used, the user can install the controller 2 on the fixing belt through the first snap buckle 21 and the second snap buckle 22. When the device is not needed, the user can remove the controller 2 to reduce the overall storage difficulty of the device.

[0043] In actual use, due to the difference in head circumference of different users, the ear positions of different users may also vary. To ensure that the user's ear can smoothly enter the receiving groove 42, the ear stimulation component in this embodiment can also be adjusted on the fixing belt according to actual needs.

[0044] In order to realize the position adjustment function of the ear stimulation component, a receiving interlayer may be provided inside the fixing belt, and a stopper may be provided inside the receiving interlayer. Accordingly, a mounting cutout 14 communicating with the receiving interlayer should be provided on the side of the fixing belt where the electrical stimulation unit is provided, and a positioning column is provided on the earmuff 41. During assembly, the positioning column should be inserted into the limiting component along the mounting cutout 14. When the position of the ear stimulation component needs to be adjusted, the user can drive the positioning column to slide inside the limiting component so that the actual position of the ear stimulation component corresponds to the position of the user's ear after the device is worn.

[0045] like Figure 3 and Figure 4 As shown, the positioning column may include a first limiting section 51, a positioning section 52 and a second limiting section 53 connected in sequence, and the outer diameters of the first limiting section 51 and the second limiting section 53 should be larger than the outer diameter of the positioning section 52. The limiting member may include: a first limiting strip 61, a second limiting strip 62 and a bearing strip 63, wherein the first limiting strip 61 and the bearing strip 63 are respectively located on both sides of the second limiting strip 62, one end of the bearing strip 63 is connected to the first limiting strip 61 through a first connecting strip 64, and the other end of the bearing strip 63 is connected to the second limiting strip 62 through a second connecting strip 65. A limiting gap is formed between the first limiting strip 61 and the second limiting strip 62, and a deformation gap is formed between the second limiting strip 62 and the bearing strip 63, and the limiting gap includes a plurality of locking sections 66 and a plurality of connecting sections 67 arranged alternately, and the inner diameter of the locking section 66 is equal to the outer diameter of the positioning section 52, and the inner diameter of the connecting section 67 is smaller than the outer diameter of the positioning section 52.

[0046] When the positioning column is inserted into the limiting member, the positioning section 52 of the positioning column will enter the limiting gap. Since the outer diameters of the first limiting section 51 and the second limiting section 53 are both larger than the outer diameter of the positioning section 52, the positioning column can be prevented from being separated from the limiting member. When the positioning column is inside the locking section 66, since the inner diameter of the locking section 66 is equal to the outer diameter of the positioning section 52, the positioning column will be fixed inside the locking section 66. When it is necessary to adjust the position of the ear stimulation component, the user can apply a force to the positioning column to drive the positioning section 52 to slide inside the limiting gap. Since the inner diameter of the connecting section 67 is smaller than the outer diameter of the positioning section 52, when the positioning section 52 passes through the area where the connecting section 67 is located, the limiting member will undergo elastic deformation (i.e., the second limiting strip 62 deforms in the direction close to the bearing strip 63, and the first limiting strip 61 deforms in the direction away from the bearing strip 63), so that the positioning section 52 can move smoothly to the inside of the next locking section 66.

[0047] Optionally, to prevent the position limiter from moving during the position adjustment of the ear stimulation assembly, a connecting ear 68 may be provided on the first connecting rod and the second connecting rod, and a positioning hole 681 for accommodating the buckle may be provided on the connecting ear 68. When the device is produced and processed, the staff may fix the position limiter inside the accommodating interlayer by means of the buckle, so that the position limiter can obtain a good position fixing effect.

[0048] In order to improve the comfort of the user when wearing the device, the fixing belt in this embodiment may include: a bearing layer 11, a protective layer 12 and a contact layer 13, wherein the protective layer 12 is arranged on the side of the bearing layer 11 close to the controller 2, and the protective layer 12 is made of a stretch fabric material, and the contact layer 13 is arranged on the side of the bearing layer 11 close to the electrical stimulation unit, and the contact layer 13 is made of a short flannel material. The protective layer 12 made of a stretch fabric material can improve the durability of the fixing belt and make the fixing belt have elastic deformation ability, and the contact layer 13 made of a short flannel material can improve the softness and fit of the fixing belt, thereby improving the user's experience.

[0049] In addition, in order to improve the wearing convenience of the fixing belt, the device may be provided with a fleece-surface Velcro 15 at one end of the fixing belt, and a thorn-surface Velcro 16 at the other end, and the fleece-surface Velcro 15 should be provided on the side of the fixing belt provided with the controller 2, and the thorn-surface Velcro 16 should be provided on the side of the fixing belt provided with the electrical stimulation unit. When the user wears the device, the fixing belt can be wrapped around the head, and the two ends of the fixing belt can be connected by bonding the fleece-surface Velcro 15 and the thorn-surface Velcro 16.

[0050] In actual use, since the user may use other wearable devices (such as VR glasses or eye massagers) while using the present device, as another optional implementation of the present embodiment, the auricular acupoint transcutaneous electrical stimulation device may also include an accessory strap 7. Specifically, one end of the accessory strap 7 should be connected to the fixing belt, and the other end is provided with a third snap fastener 71, and a plurality of fourth snap fasteners that match the third snap fasteners 71 are provided on the accessory strap 7. When other wearable devices are not needed, the user can wrap the accessory strap 7 around the fixing belt to prevent the accessory strap 7 from blocking the user's line of sight. When other wearable devices are needed, the user can use the accessory strap 7 to tie other wearable devices to the fixing belt of the present device, and buckle the third snap fastener 71 on the corresponding fourth snap fastener according to the size of the other wearable devices, thereby improving the combination effect between other wearable devices and the present device and preventing the wear reliability of other wearable devices from being affected by the present device.

[0051] The effects of the above scheme are described below:

[0052] The present embodiment provides an ear acupoint transcutaneous electrical stimulation device, which can be worn on the user's head through a fixing strap, and can adjust the position of the ear stimulation component according to actual needs, so that the ears of users with different head circumferences can smoothly enter the receiving groove, thereby performing transcutaneous electrical stimulation treatment on the ear acupoints. Secondly, the present device can adjust and lock the position of the ear stimulation component through the cooperation of the limiter and the positioning column, which is convenient for the user to operate. In addition, the present device can also improve the durability and elasticity of the fixing strap through a protective layer, and improve the comfort of the user when wearing the device by setting a contact layer, thereby improving the user's experience.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
