Description

Technical Field

[0001] This utility model relates to the field of neck pillow technology, and in particular to a neck pillow with electrical stimulation function. Background Technology

[0002] Motion sickness is common when traveling by car or boat. During travel, there are often complex situations such as acceleration, deceleration, bumps, and turns. Passengers' bodies need to constantly adjust their posture to maintain balance. When the tolerance for the intensity and duration of these adjustments reaches a limit, motion sickness occurs.

[0003] Current methods for preventing and alleviating motion sickness generally involve taking motion sickness medication, wearing motion sickness glasses, and using shock-absorbing mechanisms to maintain passenger stability, but the prevention and relief effects are not ideal. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a neck pillow with electrical stimulation function that has a good effect on preventing and relieving motion sickness.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a neck pillow with electrical stimulation function, comprising:

[0006] The neck pillow body, the first electrical stimulation contact, the second electrical stimulation contact, and the control module;

[0007] The first electrical stimulation contact is located at one end of the neck pillow body, and the second electrical stimulation contact is located at the other end of the neck pillow body. The neck pillow body is a flexible component, and the user can bend the neck pillow body according to the position of the mastoid process behind their ears so that the first electrical stimulation contact and the second electrical stimulation contact are respectively attached to the mastoid process behind their ears.

[0008] The control module is located in the neck pillow body and is electrically or communicatively connected to the first and second electrical stimulation contacts. The control module can control the first and second electrical stimulation contacts to generate electrical stimulation on the mastoid process behind the user's ear by passing a preset stimulation current. The stimulation current is less than the safe current value for the human body.

[0009] Furthermore, the neck pillow body includes rigid foam and soft foam, with the soft foam disposed on the rigid foam. The user can bend the neck pillow body to deform the rigid foam and / or the soft foam.

[0010] When a user wears the neck pillow around their neck, with the first and second electrical stimulation contacts respectively against the mastoid processes behind their ears, their neck rests on the soft foam.

[0011] Furthermore, the neck pillow body has a built-in power supply, which is electrically connected to the first electrical stimulation contact, the second electrical stimulation contact, and the control module; or,

[0012] The neck pillow body is equipped with a power input structure, through which an external power source is connected to supply power to the neck pillow.

[0013] Furthermore, the stimulation current is less than or equal to 3.5 mA.

[0014] Furthermore, the stimulation current is configured as a 1 kHz sinusoidal current of less than or equal to 3.5 mA.

[0015] Furthermore, the outer surface of the neck pillow body is provided with a covering cover;

[0016] The first electrical stimulation contact and the second electrical stimulation contact are disposed on the covering sleeve.

[0017] Furthermore, both the first and second electrical stimulation contacts include a base and a cover. The base is disposed on the covering cover, and the cover is disposed on the base and is in communication with the base.

[0018] Furthermore, the cover is provided with a mounting hole, the base is inserted into the mounting hole from the inside of the cover to the outside, and the cover is snapped onto the base from the outside of the cover.

[0019] Furthermore, the base includes a boss and a retaining edge disposed around the boss, the retaining edge being located inside the covering sleeve, and the boss passing through the mounting hole from the inside to the outside; the cover is snapped onto the boss.

[0020] A spring extends outward from the protrusion, and the spring abuts against the inner wall of the cover. When the cover is engaged with the protrusion, the inner wall of the cover presses against the spring, causing the spring to deform elastically and adhere tightly to the inner wall of the cover.

[0021] Furthermore, both the first and second electrical stimulation contacts are waist-shaped.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] In this invention, a first electrical stimulation contact and a second electrical stimulation contact are respectively provided at both ends of the neck pillow body, and the neck pillow body itself is designed as a flexible component. Users can bend the neck pillow body according to the position of their two mastoid processes behind their ears, so that the first and second electrical stimulation contacts are respectively positioned against their two mastoid processes. The control module controls the first and second electrical stimulation contacts to apply a stimulation current less than the safe current value for the human body to the user's two mastoid processes behind their ears, which can improve the user's tolerance to motion sickness and effectively prevent and alleviate motion sickness in scenarios such as car or boat travel, with good results.

[0024] In this invention, the neck pillow body includes a rigid foam and a soft foam disposed on the rigid foam. The rigid foam has a relatively small deformation under external force and serves as the supporting frame of the neck pillow. The soft foam is a comfort component and has a relatively large deformation under external force. During use, the user's neck rests against the soft foam to ensure passenger comfort.

[0025] In this invention, a cover is provided on the outer surface of the neck pillow body, and the cover is provided with mounting holes. Both the first and second electrical stimulation contacts include a base and a cover. The base is inserted into the mounting hole from the inside out, and the cover is snapped onto the base from the outside, ensuring that the first and second electrical stimulation contacts are easy to install. A spring extends outward from the base. After the cover is snapped onto the base, the spring is squeezed so that the spring is against the cover, ensuring the conductivity and good contact between the cover and the base.

[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0038] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0039] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0042] like Figures 1-6As shown in the figure, a neck pillow with electrical stimulation function in this embodiment mainly includes: a neck pillow body 2, a first electrical stimulation contact 3, a second electrical stimulation contact 4, and a control module (not marked in the figure);

[0043] The first electrical stimulation contact 3 is located at one end of the neck pillow body 2, and the second electrical stimulation contact 4 is located at the other end of the neck pillow body 2. The neck pillow body 2 is a flexible component. The user 1 can bend the neck pillow body 2 according to the position of the mastoid process behind their ears, so that the first electrical stimulation contact 3 and the second electrical stimulation contact 4 are respectively placed against the mastoid process behind the user 1's ears. It should be explained that for users 1 with different body types, the neck pillow body 2 can be bent to deform the neck pillow body 2, thereby adjusting the position of the first electrical stimulation contact 3 and the second electrical stimulation contact 4, so that the first electrical stimulation contact 3 and the second electrical stimulation contact 4 can be accurately applied to the mastoid process behind the user 1's ears. The mastoid process is the vestibular organ of the user 1's ear 10 (inner ear). The mastoid process is the attachment point of many neck and head muscles in the human body. The contraction and relaxation of these muscles are crucial for maintaining head posture.

[0044] The control module is located in the neck pillow body 2 and is electrically or communicatively connected to the first electrical stimulation contact 3 and the second electrical stimulation contact 4. That is, the control module can control the first electrical stimulation contact 3 and the second electrical stimulation contact 4 via wired or wireless means. The control module can control the first electrical stimulation contact 3 and the second electrical stimulation contact 4 to generate electrical stimulation on the mastoid region behind the ear of the user 1 through a preset stimulation current. The stimulation current is less than the safe current value of the human body (generally less than 30 mA) to ensure safety.

[0045] Typically, many wearable GVS devices can effectively improve a user's tolerance to motion sickness by monitoring head movements, predicting the risk of motion sickness, and providing early electrical stimulation intervention. The control module in this embodiment can utilize the controller found in existing wearable GVS devices.

[0046] In practical use, the neck pillow in this embodiment has a first electrical stimulation contact 3 and a second electrical stimulation contact 4 respectively set at both ends of the neck pillow body 2, and the neck pillow body 2 itself is set as a flexible component. User 1 can bend the neck pillow body 2 according to the position of their two mastoid processes behind their ears, so that the first electrical stimulation contact 3 and the second electrical stimulation contact 4 are respectively placed against the position of their two mastoid processes behind their ears. The control module controls the first electrical stimulation contact 3 and the second electrical stimulation contact 4 to provide electrical stimulation to the position of the user 1's two mastoid processes behind their ears with a stimulation current less than the safe current value for the human body. This can improve the user 1's tolerance to motion sickness and can effectively prevent and alleviate motion sickness in scenarios such as traveling by car or boat, with good results.

[0047] It should be explained that in this embodiment, the stimulation current is less than or equal to 3.5 mA, a value far below the safe current value for the human body. When a small stimulation current of less than or equal to 3.5 mA is applied to the mastoid process behind the ear, an artificial potential difference is generated, which can regulate the feedback from the vestibular system, helping it adapt quickly and reducing sensory impact. The vestibular system, located in the inner ear, plays a crucial role in perceiving head position and direction of movement, influencing functions such as balance, spatial orientation, and gaze stability. Therefore, applying this small stimulation current to the mastoid process behind the passenger's ear can effectively alleviate or prevent motion sickness, desensitizing the user to motion sickness symptoms.

[0048] The stimulation current of less than or equal to 3.5 mA is a relatively effective and safe current intensity. This stimulation current is far below the human perception threshold and danger threshold. It will usually only cause the user to experience a slight tingling sensation or a slight change in balance, without causing pain or muscle spasms.

[0049] Furthermore, the stimulation current is configured as a 1 kHz sinusoidal current of less than or equal to 3.5 mA. This frequency of sinusoidal current can produce a good balance effect on the human body. The magnitude and frequency of the stimulation current take into account effectiveness, comfort and safety.

[0050] In this embodiment, the stimulation current of the first electrical stimulation contact 3 and the second electrical stimulation contact 4 is controlled to be less than or equal to 3.5 mA (far less than the safe current for the human body), which ensures safety and significantly improves the passenger's tolerance time and comfort. When user 1 is traveling by car or boat, using the neck pillow with electrical stimulation function in this embodiment can effectively prevent or alleviate motion sickness, and the prevention and relief effects are good.

[0051] The neck pillow body 2 of this embodiment includes a rigid foam 21 and a soft foam 22, as well as a covering cover 23 covering the outer surfaces of the rigid foam 21 and the soft foam 22. The soft foam 22 is disposed on the rigid foam 21. It should be explained that the rigid foam 21 and the soft foam 22 are relative terms. The rigid foam 21 has a higher hardness and the soft foam 22 has a lower hardness. Under the same external force, the rigid foam 21 deforms relatively less, while the soft foam 22 deforms relatively more.

[0052] During use, user 1 can bend the neck pillow body 2 to deform the hard foam 21 and / or soft foam 22 to adjust the position of the first electrical stimulation contact 3 and the second electrical stimulation contact 4 to fit users of different body types.

[0053] When user 1 wears the neck pillow around their neck, with the first electrical stimulation contact 3 and the second electrical stimulation contact 4 respectively against the mastoid processes behind their ears, their neck rests against the soft foam 22. In this embodiment, the rigid foam 21 experiences relatively small deformation under external forces, serving as the supporting frame of the neck pillow. The soft foam 22, being a comfort component, experiences relatively large deformation under external forces. During use, user 1's neck rests against the soft foam 22, ensuring passenger comfort.

[0054] like Figures 5-6 and combined Figure 1 As shown, the outer surface of the neck pillow body 2 is equipped with a covering cover 23, which can be made of materials such as leather, to cover the hard foam 21 and soft foam 22. The first electrical stimulation contact 3 and the second electrical stimulation contact 4 are disposed on the covering cover 23, and both the first electrical stimulation contact 3 and the second electrical stimulation contact 4 are waist-shaped to facilitate contact with the mastoid process behind the ear of the user 1.

[0055] Specifically, both the first electrical stimulation contact 3 and the second electrical stimulation contact 4 include a base 341 and a face cover 342. The base 341 is disposed on the covering face cover 23, and the face cover 342 is disposed on the base 341 and is electrically connected to the base 341. When the user 1 wears the neck pillow, the face cover 342 is in direct contact with the user 1's skin. The covering face cover 23 has a mounting hole, and the base 341 passes through the mounting hole from the inside of the covering face cover 23 outward. The base 341 facilitates the installation of the face cover 342. The face cover 342 is snapped and fixed to the base 341 from the outside of the covering face cover 23 and is electrically connected to the base 341 to ensure that current can flow through the base 341 to the face cover 342 and to the mastoid process area behind the user 1's ear to form electrical stimulation. The cover 23 is sandwiched between the base 341 and the cover 342, ensuring that the installation positions of the first electrical stimulation contact 3 and the second electrical stimulation contact 4 are fixed and reliable. The base 341 and the cover 342 are located on the inner and outer sides of the cover 23, respectively, which facilitates the installation of the first electrical stimulation contact 3 and the second electrical stimulation contact 4.

[0056] More specifically, both the base 341 and the cover 342 are metal parts, which can achieve electrical conductivity when they come into contact. Both the base 341 and the cover 342 can be formed by stamping, ensuring ease of manufacturing. The base 341 is electrically connected to the power supply and / or control module through wires.

[0057] The base 341 includes a boss 341A and a retaining edge 341B disposed around the boss 341A. The retaining edge 341B is located inside the covering sleeve 23 and serves to limit the base 341 from falling outward from the inside of the side wing sleeve. The boss 341A passes through the mounting hole from the inside to the outside, and the cover 342 is snapped and fixed on the boss 341A. Furthermore, a spring piece 341C extends outward from the boss 341A, that is, an upward-curved spring piece 341C is formed on the boss 341A. The spring piece 341C abuts against the inner wall of the cover 342 and contacts the cover 342. Furthermore, when the cover 342 is engaged with the boss 341A, the inner wall of the cover 342 presses against the spring piece 341C, causing the spring piece 341C to undergo elastic deformation. The spring piece 341C is tightly attached to the inner wall of the cover 342, ensuring good contact and reliable conduction between the cover 342 and the seat, and preventing it from easily loosening.

[0058] Optionally, the neck pillow in this embodiment can be either a built-in power supply or an external power supply. That is, the neck pillow body 2 has a built-in power supply, which is electrically connected to the first electrical stimulation contact 3, the second electrical stimulation contact 4, and the control module, providing power to the various electrical components. Alternatively, the neck pillow body 2 can be equipped with a power access structure, which can be a power socket or power cord, connecting to an external power source to supply power to the neck pillow.

[0059] In this solution, user 1 uses a neck pillow with electrical stimulation function, which can effectively alleviate and prevent motion sickness in scenarios such as riding in a car or boat, and the alleviation and prevention effects are good.
