Description

Technical Field

[0001] This utility model relates to a sleep aid. Background Technology

[0002] As is well known, among the twelve cranial nerves, the vagus nerve is considered a unique and purely visceral nerve, with the widest distribution throughout the body, connecting and influencing our nervous system. When stimulated, it sends signals back to the hippocampus, cingulate gyrus, and other central nervous systems, causing parasympathetic excitation and sympathetic inhibition, thereby affecting the body's physical and mental state and promoting relaxation.

[0003] Vagus nerve stimulation is a form of neuromodulation widely used in the medical field. With technological advancements, its applications have expanded to include stress relief, sleep aid, and other everyday uses. The concha of the ear is a region richly innervated by the vagus nerve in the external auditory canal. Recent studies have discovered that electrical stimulation of the vagus nerve's innervation areas on the body surface may also produce similar effects. Based on this, vagus nerve stimulation techniques through the concha have emerged, along with corresponding ear-hook vagus nerve stimulation devices.

[0004] For example, Chinese invention patent application CN101797415A (application number 201010111662.8) discloses a sleep aid device with a headphone-like structure. This device includes a push-rod brush to stimulate the vagus nerve in the ear canal to achieve a sleep-inducing effect. However, this type of sleep aid device is prone to slipping and falling off during use. To prevent it from slipping off, a greater clamping force is required, which can actually disrupt the user's sleep. Furthermore, the effectiveness of electrical stimulation varies from person to person. Within the safe low-voltage range for the human body, excessively high body resistance can lead to poor electrical stimulation and a weak sleep-inducing effect. Earwax buildup is a major cause of excessive body resistance, and existing devices for vagus nerve stimulation cannot clean this buildup, resulting in very limited electrical stimulation effects. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a sleep aid that can improve wearing stability and comfort, clean the user's ear canal, and thus enhance the effect of vagal stimulation, in contrast to the above-mentioned prior art.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a sleep device, including a stimulator that can be worn in the ear, the stimulator including a base, a control module, and a first electrode head connected to the base, the first electrode head being electrically connected to the control module, characterized in that: it further includes a second electrode head and a driving mechanism that are electrically connected to the control module, the second electrode head being connected to the driving end of the driving mechanism and based on the driving vibration of the driving mechanism.

[0007] To improve wearing comfort, the first electrode head is fin-shaped to fit the concha cymba inside the ear, and the second electrode head is cylindrical to fit the ear canal inside the ear.

[0008] Preferably, both the first electrode head and the second electrode head include a conductive metal body and a flexible conductive sleeve fitted over the body.

[0009] Preferably, the driving mechanism includes a vibrator, and the second electrode head is sleeved outside the vibrator.

[0010] In order to simultaneously drive the rotation of the second electrode head, the driving mechanism further includes a driver, and the vibrator is disposed at the driving end of the driver and rotates under the drive of the driver.

[0011] To effectively collect clean dirt, the sidewall of the second electrode head is provided with a notch.

[0012] Alternatively, the control module may be disposed within the substrate.

[0013] To further improve wearing comfort and stability, and enhance sleep-aiding effects, the device also includes an eye mask body that can cover the eyes and a fixing strap connecting the two ends of the eye mask body. The control module is located inside the eye mask body.

[0014] Preferably, each end of the eye mask is flexibly connected to a stimulation element.

[0015] Simply put, the stimulation element is flexibly connected to the eye mask body via an electrical connection line between the substrate and the control module.

[0016] Compared with existing technologies, the advantages of this invention are as follows: The sleep aid in this invention allows the stimulation component to be independently fitted and installed inside the ear, improving the stability and comfort of installation. Furthermore, the second electrode head is equipped with a drive mechanism that can drive it to vibrate. Thus, during use, the ear canal area can be cleaned by driving the second electrode head through the drive mechanism. The cleaned skin has lower resistance, resulting in better vagal stimulation during electrical stimulation and thus enhancing the sleep-aiding effect. Attached Figure Description

[0019] Figure 3 for Figure 2 The exploded diagram. Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, the sleep aid in this embodiment includes a wearable ear stimulation device 100, which can be used relatively independently, such as a wireless earphone. Since the sleep aid is designed to promote sleep, to further enhance the sleep-aiding effect and improve wearing comfort and stability, this embodiment also includes an eye mask 5 that covers the eyes and a fixing strap 6 connecting the two ends of the eye mask 5. The user uses the fixing strap 6 to wear the eye mask 5 on their head, covering the eyes and blocking external light, thereby improving the sleep-aiding effect. Additionally, various sleep-aiding modules can be provided on the eye mask 5 as needed, such as a massage module that can massage the area around the eyes.

[0022] The location of the control module is determined based on whether or not the eye mask body 5 is set. If the eye mask body 5 is not set, the control module can be set in the stimulation element 100. If the eye mask body 5 is set, the control module can be set inside the eye mask body 5.

[0023] like Figure 2 and Figure 3 As shown, the stimulation device 100 includes a substrate 1, a control module, a first electrode head 2, a second electrode head 3, and a drive mechanism 4. The control module is electrically connected to the first electrode head 2, the second electrode head 3, and the drive mechanism 4, so that the first electrode head 2, the second electrode head 3, and the drive mechanism 4 work under the control of the control module.

[0024] When the control module is located within the stimulus element, the control module is specifically located within the substrate 1.

[0025] The first electrode head 2 is connected to the base 1. The first electrode head 2 is fin-shaped and designed to fit the position of the cymba concha inside the ear. The fin-shaped first electrode head 2 ensures the stability of its placement within the cymba concha. The second electrode head 3 is cylindrical and better fits the position of the ear canal inside the ear. Both the first electrode head 2 and the second electrode head 3 include a conductive metal body and a flexible conductive sleeve fitted over the body. This conductive sleeve can be made of conductive silicone or conductive sponge.

[0026] The driving mechanism 4 is mounted on the base 1, and the second electrode head 3 is connected to the driving end of the driving mechanism 4 and vibrates based on the driving mechanism 4. When the second electrode head 3 vibrates based on the driving mechanism 4, it cleans the dirt in the ear acupoint, thereby reducing the skin resistance at the site of the ear acupoint electrical stimulation and enhancing the sleep-aiding effect of electrical stimulation.

[0027] To ensure the cleanliness of the second electrode head 3 during vagal stimulation, the driving mechanism 4 in this embodiment specifically includes a vibrator 41 and a driver 42. The vibrator 41 is connected to the driving end of the driver 42, and the second electrode head 3 is sleeved on the vibrator 41. The driver 42 can be a motor, which can drive the vibrator 41 to rotate, thereby causing the second electrode head 3 to rotate synchronously.

[0028] To effectively collect cleaned dirt, a notch 31 is provided on the side wall of the second electrode head 3. During cleaning of the stimulation area inside the ear canal, a portion of the second electrode head 3 is in close contact with the stimulation area. The control module controls the vibrator 41 to vibrate, achieving stimulation of the ear canal based on friction and vibration. After cleaning, the control module controls the driver 42 to rotate the second electrode head 3, collecting the vibrated dirt from the ear canal into the notch 31 for cleaning after the stimulation head has finished its work. Then, the driver 42 drives the second electrode head 3 to rotate so that the other portion of the second electrode head 3 contacts the stimulation area inside the ear canal, ensuring that the clean portion of the second electrode head 3 contacts the stimulation area. After cleaning, the skin resistance at the stimulation area is reduced. The control module controls the first electrode head 2 and the second electrode head 3 to be simultaneously energized, allowing simultaneous skin energization for vagal stimulation, achieving a sleep-inducing effect.

[0029] To ensure balanced stimulation of the ears, a stimulation element is flexibly connected to both ends of the eye mask body 5. Specifically, the stimulation element is flexibly connected to the eye mask body 5 via an electrical connection line between the base 1 and the control module.

[0030] The sleep aid device of this invention features a stimulation component that can be independently fitted and installed inside the ear, improving stability and comfort during installation. Furthermore, a drive mechanism 4 is included for the second electrode head 3 to drive it to vibrate. Thus, during use, the drive mechanism 4 drives the second electrode head 3 to clean the area inside the ear canal. Cleaned skin has lower resistance, resulting in better vagal stimulation during electrical stimulation and thus enhancing the sleep-inducing effect.
