Description

Technical Field

[0001] This application relates to the field of massage device technology, and more particularly to a neck massager. Background Technology

[0002] In related technologies, neck massagers are used to massage a user's neck. There are generally two ways to fix a neck massager to the user's neck: First, the neck massager is fixed to the neck by a clip. In this method, the massager only massages a single area of ​​the neck. Second, the neck massager is equipped with a pull cord. The user tightens the pull cord to fix the neck massager to their neck. In this method, because the user's pulling force is relatively fixed, the neck massager is also fixed to a single position on the neck, and during the massage, the massager only massages a single area of ​​the neck. Summary of the Invention

[0003] To address the aforementioned issues, this application provides a neck massager that solves the problem of limited massage positions in neck massagers.

[0004] This application provides a neck massager, including a wearing bracket and two massage components. The wearing bracket has a neck-wrapping space and a neck-wrapping section that surrounds the back of the user's neck. The two massage components are spaced apart from each other on the neck-wrapping section of the wearing bracket, and when worn, they respectively fit against the two sides of the back of the user's neck relative to the cervical spine. Each massage component includes a rotatable kneading element on the side facing the user's neck. The minimum distance between the two kneading elements is greater than or equal to 20 mm and less than or equal to 26 mm. Each kneading element has a rotation axis. The rotation axis of the kneading device intersects the sagittal plane of the human body within the neck-circling space, and the angle between the rotation axis and the sagittal plane is α, where α is greater than or equal to 21° and less than or equal to 31°; and / or, the rotation axis intersects the coronal plane of the human body within the neck-circling space, and the projection of the angle formed by the intersection of the rotation axis and the coronal plane onto the sagittal plane is β, where β is greater than or equal to 73° and less than or equal to 83°; when the two kneading devices simultaneously knead and massage the user's neck, the two kneading devices rotate in opposite directions and both are in contact with the user's neck, so that the kneading devices can move up and down along the user's neck.

[0005] Based on the above embodiments, this application provides a neck massager, including a wearing bracket and two massage components. The wearing bracket has a neck-wrapping space to accommodate the user's neck, and also includes a neck-wrapping section that surrounds the back of the user's neck. The neck-wrapping section can support the other components of the neck massager. The two massage components are spaced apart on the neck-wrapping section of the wearing bracket. When the user wears the neck massager, the two massage components are respectively attached to the back of the user's neck on both sides relative to the cervical spine, so that the neck massager can knead and massage both sides of the user's neck. When the two kneading components knead and massage the user's neck simultaneously, the two kneading components rotate in opposite directions and are both in line with... The device makes contact with the user's neck so that the kneading component can move up and down along the user's neck. By limiting the angle between the rotation axis and the sagittal plane, the device avoids reducing the fit between the kneading component and the user's neck due to an excessively large or small angle. Furthermore, limiting the angle α increases the friction between the kneading component and the user's neck, allowing the kneading component to better drive the support frame to move up and down along the user's neck. There is an angle between the extension direction of the rotation axis and the radial direction of the user's neck, and there is also a deflection angle between the extension direction of the rotation axis and the radial direction of the user's neck. This allows the kneading component to fit more closely to the user's neck when wearing the neck massager.

[0006] Furthermore, as the kneading components move up and down along the user's neck, the two kneading components rotate in opposite directions for at least one revolution, and both kneading components remain in contact with the user's neck during the rotation.

[0007] Based on the above embodiments, by limiting the number of rotations of the two kneading components, the minimum travel distance of the kneading components as they move up and down the user's neck is limited. This allows the neck massager to have a larger travel distance on the user's neck, increasing the massage area. Furthermore, during rotation, both kneading components remain in contact with the user's neck, ensuring stable traction and friction between the kneading components and the user's neck during the up-and-down movement, thus making the neck massager more stable during this process.

[0008] Furthermore, when the kneading components move up and down along the user's neck, the minimum stroke of the two kneading components moving up and down is not less than 10mm.

[0009] Based on the above embodiments, the minimum stroke of the two kneading components is limited so that when the kneading components knead and massage a certain position on the user's neck, the kneading components can perform a small range of reciprocating movements at that position, thereby achieving a small range of kneading and massage on the user's neck, so that the neck massager can bring a more comfortable massage effect to the user.

[0010] Furthermore, the minimum distance between the two kneading pieces is greater than or equal to 20 mm and less than or equal to 26 mm.

[0011] Based on the above embodiments, this embodiment constrains the minimum distance between the two kneading parts. On the one hand, it can increase the fit between the kneading parts and the user's neck, making the user's neck have a more comfortable massage effect. On the other hand, it can also increase the contact area between the kneading parts and the user's neck, so that the neck massager in this embodiment can have a larger massage area for the user's neck.

[0012] Furthermore, each kneading component has a rotation axis, and the kneading component includes a support body and multiple massage protrusions. The support body has a support surface and rotates about the rotation axis. The multiple massage protrusions are spaced apart on the support surface for contact with the user's neck.

[0013] Based on the above embodiments, the support body, as a load-bearing component in the kneading member, provides a load-bearing foundation for the setting of massage protrusions and other components. The support body rotates around the rotation axis, which in turn drives the rotation of the massage protrusions, so that the user has a more immersive massage experience. Multiple massage protrusions are spaced apart on the support surface. The massage protrusions contact the user's neck. The setting of massage protrusions can increase the contact area between the kneading member and the user's neck, thereby increasing the massage area of ​​the kneading member on the user's neck.

[0014] Furthermore, the inner surface of each massage protrusion near the axis of rotation has a first slope relative to the support surface, and the outer surface of the massage protrusion away from the axis of rotation has a second slope relative to the support surface, with the first slope being greater than the second slope.

[0015] Based on the above embodiments, this embodiment sets the first slope to be greater than the second slope so that the slope of the outer surface of the massage protrusion is gentler than the slope of the inner surface, thereby increasing the contact area between the massage protrusion and the user's neck.

[0016] Furthermore, the surface of the massage protrusion is smooth, and the kneading component also includes a heating film, which is fixedly connected to the side of the support body opposite to the support surface.

[0017] Based on the above embodiments, the smooth surface can increase the friction between the massage protrusions and the user's neck, and the heating film can also promote the secretion of sweat from the skin by the massage protrusions, thereby increasing the humidity of the skin surface. In turn, during the contact between the massage protrusions and the user's neck, the friction between the massage protrusions and the user's neck can be further increased, allowing the neck massager to move more stably up and down along the user's neck.

[0018] Furthermore, each massage protrusion has multiple sequentially connected ridges. The connecting line between two adjacent ridges is a ridge line that is recessed into the massage protrusion. The ridge line extends from the top of the massage protrusion toward the support surface, and the distance between two adjacent ridge lines gradually increases along the extension direction of the ridge line.

[0019] Based on the above embodiments, the ridges increase the friction between the massage protrusions and the user's neck, thereby allowing the neck massager to move more stably up and down along the user's neck.

[0020] Furthermore, multiple massage protrusions are arranged around a rotation axis. The massage protrusion with the largest projected area on the support surface is the first protrusion, and the massage protrusion with the smallest projected area on the support surface is the second protrusion. Along the circumferential direction of the multiple massage protrusions, the massage protrusion located between the first and second protrusions is the third protrusion. The projected areas of the first, third, and second protrusions on the support surface gradually decrease. And / or multiple massage protrusions are arranged around a rotation axis. The massage protrusion with the highest height relative to the support surface is the first protrusion, and the massage protrusion with the lowest height relative to the support surface is the second protrusion. Along the circumferential direction of the multiple massage protrusions, the massage protrusion located between the first and second protrusions is the third protrusion. The heights of the first, third, and second protrusions relative to the support surface gradually decrease.

[0021] Based on the above embodiments, when the multiple massage protrusions rotate around the rotation axis, the different massage protrusions have different pressure intensities and different pressure areas when they come into contact with the user's neck. This allows the kneading component to provide the user with a varied massage experience during rotation, making the neck massager more comfortable for the user's neck.

[0022] Furthermore, the plurality of massage protrusions include at least one first protrusion and a plurality of second protrusions. The orthographic projection area of ​​the first protrusion on the support surface is greater than the orthographic projection area of ​​the second protrusion on the support surface, and the height of the first protrusion relative to the support surface is greater than the height of the second protrusion relative to the support surface. At least one second protrusion is provided on each of the opposite sides of each first protrusion.

[0023] Based on the above embodiments, the first protrusion has a greater massage force and a wider massage area than the second protrusion. The combination of the two can enhance the user's perception of the squeezing force of the kneading component, thereby providing the user with a more obvious change in squeezing force and improving the massage effect of the kneading component.

[0024] Furthermore, the tip of the first protrusion is further away from the axis of rotation than the tip of the second protrusion, and / or the outer surface of the first protrusion is further away from the axis of rotation than the outer surface of the second protrusion.

[0025] Based on the above embodiments, the kneading component provides varying massage intensity and pressure to the user's neck as it rotates, thereby enhancing the user's massage experience.

[0026] Furthermore, the surface of the massage protrusion is a conical or spherical surface, and the support body includes a support plate and a support seat. The support plate is disposed on the support seat, and the support surface is the surface of the support plate facing away from the support seat. In the direction from the rotation axis to the edge of the support surface, the support surface is inclined to the support seat.

[0027] Based on the above embodiments, the cone and spherical surfaces can further increase the contact area between the massage protrusions and the user's neck. The inclined support surface of the support base will make the massage protrusions fit closer to the user's skin when rotating, thereby further increasing the contact area between the massage protrusions and the user's skin and improving the massage effect.

[0028] Furthermore, the massage component also includes a base, a detection element, and a reflector. The base is disposed on the wear bracket; the detection element is disposed on the surface of the base facing the support; the reflector is disposed on the surface of the support facing the detection element, and the reflectivity of the reflector is different from the reflectivity of the surface of the support facing the detection element, or the surface of the reflector has two reflective areas with different reflectivities.

[0029] Based on the above embodiments, when there is a difference in the rotation stroke of the two kneading components, the movement stroke of the kneading components can be compensated so that the two kneading components gradually restore the same rotation stroke.

[0030] Furthermore, the massage component also includes a drive unit and a reduction gearbox. The drive unit is mounted on the wear bracket and has a drive shaft. The reduction gearbox is connected to the drive unit and has an output shaft coaxial with the rotation axis. The output shaft is connected to the kneading component. The wear bracket has a plane of symmetry, and the two massage components are arranged axially symmetrically about the plane of symmetry. In the same massage component, the drive shaft is closer to the plane of symmetry than the output shaft.

[0031] Based on the above embodiments, the drive shaft and the rotation axis in this embodiment are not coaxially arranged, and since the drive shaft is closer to the plane of symmetry than the output shaft, the massage component has a larger layout span in the length direction of the wearing bracket, and the part of the neck wrap section that is far from the plane of symmetry can also have a smaller thickness.

[0032] Furthermore, the wearable support includes an elastic segment and two handles respectively connected to both ends of the elastic segment, and two massage components are disposed on the elastic segment; when the wearable support is worn on the user's neck, both handles have a contact position with the user's shoulders, the overall center of gravity of the neck massager is further away from the elastic segment than the contact position, and the minimum distance between the two handles is greater than or equal to 15mm and less than or equal to 25mm.

[0033] Based on the above embodiments, the elastic segment can undergo elastic deformation and has the characteristic of restoring its original shape after deformation. The size constraint of the handle can make the elastic segment have a large elastic potential energy, which can ensure the structural strength of the wearing bracket and make the wearing bracket fit the user's neck more closely.

[0034] This application provides a neck massager, including a wearing bracket and two massage components. The wearing bracket has a neck-wrapping space to accommodate the user's neck. The wearing bracket also includes a neck-wrapping section that surrounds the back of the user's neck. The neck-wrapping section can support the other components of the neck massager. The two massage components are spaced apart on the neck-wrapping section of the wearing bracket. When the user wears the neck massager, the two massage components are respectively attached to the back of the user's neck on both sides relative to the cervical spine, so that the neck massager can knead and massage both sides of the user's neck. When the two kneading components knead and massage the user's neck at the same time, the two kneading components rotate in opposite directions and are both in contact with the user's neck, so that the kneading components can move up and down along the user's neck.

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] Please refer to Figure 1 This application provides a neck massager 1, including a wearing bracket 2 and two massage components 3, which are spaced apart on the wearing bracket 2 for kneading and massaging the user's neck.

[0048] The wearing bracket 2 serves as an attachment component for other components in the neck massager 1, providing a basis for the setting of the massage component 3. The wearing bracket 2 has a neck-wrapping space 21 and a neck-wrapping section 22 that surrounds the back of the user's neck. The neck-wrapping space 21 is used to accommodate the user's neck so that the wearing bracket 2 can be worn relatively stably on the user's shoulders and neck, thereby allowing the massage component 3 set on the wearing bracket 2 to knead and massage the user's neck. The neck-wrapping section 22 surrounds the back of the neck, which is the side of the neck away from the face. The neck-wrapping section 22 is usually equipped with components such as a massage mechanism so that the neck massager 1 can knead and massage the back of the user's neck.

[0049] Two massage components 3 are spaced apart on the neck-wrap section 22 of the wearing bracket 2. The massage components 3 serve as kneading components in the neck massager 1 to massage the user's neck. When the user wears the neck massager 1, the two massage components 3 are respectively attached to the back of the user's neck on both sides relative to the cervical spine, so that the neck massager 1 can knead and massage both sides of the user's neck.

[0050] Please combine Figures 1 to 3 Furthermore, each massage component 3 has a rotatable kneading element 31, which is positioned towards the user's neck for kneading and massaging the user's neck. The rotation of the kneading element 31 can be driven by a motor, which is not limited in this embodiment. When the user wears the neck massager 1, the two kneading elements 31 are used to knead and massage the back of the user's neck on both sides relative to the cervical spine. During the simultaneous kneading and massaging of the user's neck by the two kneading elements 31, the two kneading elements 31 can have opposite directions of rotation. By controlling the rotation direction of the kneading elements 31, the kneading elements 31 can move up and down along the user's neck, thereby driving the movement of the wearing bracket 2. This allows the neck massager 1 to move up and down the user's neck, enabling the neck massager 1 to change different massage positions during the massage process, solving the problem of the neck massager 1 having a single massage position.

[0051] During the kneading massage of the user's neck by the kneading component 31, friction is generated between the rotation of the kneading component 31 and the user's neck. Without considering the action of external forces, the neck massager 1 is subjected to its own weight, the friction between the kneading component 31 and the user's neck, and traction force during the massage of the user's neck.

[0052] Taking the kneading element 31 moving upwards along the user's neck as an example, the kneading element 31 fits against the user's neck and interacts with the user's neck during rotation, thereby generating traction and friction between the kneading element 31 and the user's neck. The direction of the traction component is from the lower neck to the upper neck, the direction of the friction force is from the upper neck to the lower neck, and the direction of gravity of the neck massager 1 is from the upper neck to the lower neck. That is, the direction of the traction component is opposite to the direction of the friction force and the direction of gravity. Furthermore, from... In this embodiment, the component of the traction force provided by the motor to the kneading element 31 is greater than the weight of the neck massager 1 and the friction between the kneading element 31 and the user's neck. That is, the component of the traction force does work to overcome the friction and gravity, thereby allowing the kneading element 31 to climb upward along the user's neck. Alternatively, when the component of the traction force provided by the motor to the kneading element 31 is equal to the weight of the neck massager 1 and the friction between the kneading element 31 and the user's neck, the kneading element 31 can remain stable at a certain position on the user's neck to perform kneading massage on a fixed position on the user's neck.

[0053] Taking the kneading element 31 crawling downwards along the user's neck as an example, the kneading element 31 fits against the user's neck and interacts with the user's neck during rotation, thereby generating traction and friction between the kneading element 31 and the user's neck. The direction of the traction component is from the upper neck to the lower neck, and the direction of the friction is from the lower neck to the upper neck. The direction of gravity of the neck massager 1 is from the upper neck to the lower neck. That is, the direction of the friction is opposite to the direction of the traction component and the direction of gravity. Furthermore, due to the electrical... The traction force provided by the motor to the kneading element 31 ensures that the friction between the kneading element 31 and the user's neck is less than the component of the traction force provided by the motor to the kneading element 31 and the weight of the neck massager 1. In other words, the component of the traction force can overcome the frictional force, allowing the kneading element 31 to move downwards along the user's neck. Alternatively, when the friction between the kneading element 31 and the user's neck is equal to the component of the traction force provided by the motor to the kneading element 31 and the weight of the neck massager 1, the kneading element 31 can remain stable at a certain position on the user's neck, thus providing a kneading massage to that fixed position. Please combine this with... Figures 1 to 4 It is understandable that the two kneading components 31 have a middle side that is close to each other. The middle side is the side where the two kneading components 31 are close to each other. Both kneading components 31 have a first direction A and a second direction B on the middle side. The first direction A is visually reflected on the middle side as extending from the upper part of the user's neck to the lower part of the user's neck, and the second direction B is visually reflected on the middle side as extending from the lower part of the user's neck to the upper part of the user's neck. Taking the rotation of the kneading component 31 along the first direction A as an example, when the kneading component 31 kneads and massages the user's neck, the kneading component 31 is subjected to frictional force along the second direction B. Without considering the action of external forces, the neck massager 1 is subjected to gravity along the first direction A and the component of the traction force along the first direction A. Since the motor in this embodiment provides traction force to the kneading component 31, the frictional force between the kneading component 31 and the user's neck is less than the component of the traction force provided by the motor to the kneading component 31 and the gravity of the neck massager 1. As a result, the kneading component 31 can move along the first direction A, thereby driving the neck massager 1 to move downward along the user's neck to change the massage position of the neck massager 1. Taking the rotation of the kneading component 31 along the second direction B as an example, when the kneading component 31 performs kneading massage on the user, the kneading component 31 is subjected to frictional force along the first direction A. Without considering the action of external forces, the neck massager 1 is subjected to the component of gravity along the first direction A and the component of traction force along the second direction B. Since the component of traction force provided by the motor to the kneading component 31 in this embodiment is greater than the gravity of the neck massager 1 and the frictional force between the kneading component 31 and the user's neck, the kneading component 31 can move along the second direction B, thereby driving the neck massager 1 to move upward along the user's neck, so as to change the massage position of the neck massager 1.

[0054] It can be seen that the magnitude of the traction force on the kneading element 31, the direction and magnitude of the friction force between the kneading element 31 and the user's neck, and the weight of the neck massager 1 all affect the up-and-down movement of the kneading element 31 along the user's neck. In this embodiment, by ensuring the kneading element 31 has a large traction force and changing its rotation direction, the direction of movement of the kneading element 31 along the user's neck can be controlled. This, in turn, changes the massage position of the neck massager 1 on the user's neck, thereby increasing the massage range of the neck massager 1.

[0055] In this embodiment, "without considering external forces" refers to the state where the neck massager 1 is worn on the user's neck in a natural state, without being pulled by the user's hand or subjected to other traction that keeps the neck massager 1 fixed on the user's neck, and the neck massager 1 can move under its own internal drive. That is, the neck massager 1 in this embodiment can change its massage position without the traction of the user's hand or other forces. In this embodiment, "without considering external forces" also refers to external forces such as air resistance that do not have a significant impact on the movement of the neck massager 1. Although these external forces exist, they do not have a significant impact on the movement of the neck massager 1 under its own internal drive.

[0056] In summary, this application provides a neck massager 1, including a wearing bracket 2 and two massage components 3. The wearing bracket 2 has a neck-wrapping space 21 to accommodate the user's neck, so that when the user wears the neck massager 1, the wearing bracket 2 can be stably set on the user's shoulders and neck; the wearing bracket 2 also includes a neck-wrapping section 22 that surrounds the back of the user's neck, and the neck-wrapping section 22 can provide support for the setting of other components in the neck massager 1. Two massage components 3 are spaced apart on the neck-wrap section 22 of the wearing bracket 2. When the user wears the neck massager 1, the two massage components 3 are respectively attached to the back of the user's neck on both sides relative to the cervical spine, so that the neck massager 1 can knead and massage both sides of the user's neck. Each massage component 3 includes a rotatable kneading element 31 on the side facing the user's neck. When the two kneading elements 31 knead and massage the user's neck at the same time, the two kneading elements 31 have opposite rotation directions and are both in contact with the user's neck. When kneading and massaging the user's neck, the kneading elements 31 have traction and friction with the user's neck. Under the action of traction, the kneading elements 31 can move up and down along the user's neck, thereby driving the movement of the wearing bracket 2. This allows the neck massager 1 to move up and down the user's neck, so that the neck massager 1 can change different massage positions during the massage, solving the problem of the neck massager 1 having a single massage position.

[0057] Furthermore, during the process of the kneading element 31 moving up and down along the user's neck, the two kneading elements 31 each rotate in opposite directions for at least one revolution, and during the rotation, both kneading elements 31 remain in contact with the user's neck. This embodiment limits the minimum travel distance of the kneading elements 31 moving up and down the user's neck by limiting the number of rotations in opposite directions performed by the two kneading elements 31 on the user's neck. This allows the kneading elements 31 to move up and down the user's neck over a longer distance, thereby enabling the neck massager 1 to have a larger travel distance on the user's neck. That is, the neck massager 1 can move from the lower part of the neck to the upper part of the neck, thereby increasing the massage area of ​​the neck massager 1 on the user's neck. This embodiment does not limit the specific number of rotations of the kneading element 31. The number of rotations of the kneading element 31 can be an integer or a non-integer number. For example, when the outer circumference of the kneading element 31 is small, the kneading element 31 may need to rotate two or three times to move the neck massager 1 from the lower part of the user's neck to the upper part of the user's neck. Changing the outer circumference of the kneading element 31 so that the number of rotations of the kneading element 31 on the user's neck is more than one rotation should be within the protection scope of this application embodiment.

[0058] During the rotation, both kneading elements 31 remain in contact with the user's neck. This ensures that the kneading elements 31 provide a stable and continuous kneading massage to the user's neck. Furthermore, as the kneading elements 31 move up and down the user's neck, they maintain a stable traction and friction force with the user's neck, making the neck massager 1 more stable during the up-and-down movement of the user's neck.

[0059] Furthermore, when the kneading element 31 moves up and down along the user's neck, the minimum stroke of the two kneading elements 31 is not less than 10mm. During the kneading massage of the user's neck by the kneading element 31, to provide the user with a more comfortable massage experience and a more pronounced massage sensation, this embodiment limits the minimum stroke of the two kneading elements 31. This allows the kneading element 31 to perform a small-range reciprocating motion at a specific location on the user's neck, thus achieving a small-range kneading massage and providing the neck massager 1 with a more comfortable massage effect for the user.

[0060] like Figure 4As shown, there is a minimum distance D1 between the two kneading elements 31, which is greater than or equal to 20mm and less than or equal to 26mm. In this embodiment, by constraining the minimum distance D1 between the two kneading elements 31, a clamping effect is formed between the two kneading elements 31 and both sides of the user's neck. On the one hand, this increases the fit between the kneading elements 31 and the user's neck, maintaining effective contact and preventing the kneading elements 31 from spinning freely. This allows the neck massager 1 to achieve its intended massage function and provides a more comfortable massage effect for the user's neck. On the other hand, it also increases the contact area between the kneading elements 31 and the user's neck, allowing the neck massager 1 in this embodiment to provide a larger massage area for the user's neck.

[0061] like Figure 1 and Figure 2 As shown, each kneading element 31 has a rotation axis 311, which can rotate to knead and massage the user's neck. The rotation axes 311 of the two kneading elements 31 intersect the sagittal plane C of the human body within the neck-encircling space 21, and the angle between the rotation axis 311 and the sagittal plane C is α, which is greater than or equal to 21° and less than or equal to 31°. When α is greater than or equal to 0° and less than 21°, or when α is greater than 31° and less than or equal to 180°, the fit between the kneading element 31 and the user's neck is too small. This embodiment limits the angle between the rotation axis 311 and the sagittal plane C to prevent the kneading element 31 from reducing its fit with the user's neck due to an excessively large or small angle. This maintains effective contact between the kneading element 31 and the user's neck, preventing the kneading element 31 from spinning freely. This allows the neck massager 1 to achieve its intended massage function. Furthermore, limiting the angle α increases the friction between the kneading element 31 and the user's neck, ensuring a stable massage position of the kneading element 31 on the user's neck after the kneading element 31 moves the wearing bracket 2 up and down along the user's neck. For example, when the kneading element 31 moves the wearing bracket 2 upwards to the upper part of the user's neck, the friction keeps the kneading element 31 in the upper part of the user's neck for massage.

[0062] Please combine them together Figures 1 to 3The rotation axes 311 of the two kneading elements 31 intersect the coronal plane D of the human body within the neck-encircling space 21. The angle formed by the intersection of the rotation axes 311 and the coronal plane D is β, which is greater than or equal to 73° and less than or equal to 83°. That is, there is an angle between the extension direction of the rotation axis 311 and the radial direction of the user's neck, and there is a deflection angle between the extension direction of the rotation axis 311 and the radial direction of the user's neck. This allows the kneading elements 31 to fit more closely to the user's neck when the user wears the neck massager 1, so as to maintain the kneading elements 31 and the user's neck. Effective contact with the user's neck prevents the kneading element 31 from spinning freely, allowing the neck massager 1 to achieve its intended massage function. Furthermore, by limiting the angle of β, the friction between the kneading element 31 and the user's neck is increased, ensuring the stability of the massage position of the kneading element 31 on the user's neck after the kneading element 31 moves the wearing bracket 2 up and down along the user's neck. For example, when the kneading element 31 moves the wearing bracket 2 upward to the upper part of the user's neck, the friction keeps the kneading element 31 in the upper part of the user's neck for massage.

[0063] It is understandable that the limiting effect of the angle between the rotation axis 311 and the sagittal plane C of the human body is complementary to the limiting effect of the angle between the rotation axis 311 and the coronal plane D of the human body. The limiting effects of the two angles, namely the limiting effects of the angles α and β, can cooperate with each other and complement each other.

[0064] Furthermore, the positional constraint between the two kneading elements 31 also indirectly constrains the offset angle between them. It can be understood that the extension line of the rotation axis 311 away from the user's neck intersects with the wearing bracket 2 at a point. When the minimum distance between the two kneading elements 31 is constrained, the larger the span between the two intersection points, the larger the angle between the two rotation axes 311. Similarly, when the minimum distance between the two kneading elements 31 is constrained, the smaller the span between the two intersection points, the smaller the angle between the two rotation axes 311. This embodiment combines the distance constraint between the two kneading elements 31, the angle constraint between the rotation axis 311 and the sagittal plane C, and the angle constraint between the rotation axis 311 and the coronal plane D. This increases the fit between the kneading elements 31 and the user's neck, and increases the friction between the kneading elements 31 and the user's neck, allowing the kneading elements 31 to better drive the wearing bracket 2 to move up and down along the user's neck.

[0065] Please refer to Figure 2 In some embodiments, each kneading element 31 includes a support 32 and a plurality of massage protrusions 33.

[0066] Please refer to Figure 2-4The support body 32, acting as a load-bearing component in the kneading member 31, provides a support base for the massage protrusions 33 and other components. The support body 32 rotates around the rotation axis 311, thereby driving the rotation of the massage protrusions 33 to provide the user with a more immersive massage experience. The support body 32 has a support surface 321, on which multiple massage protrusions 33 are spaced apart. The massage protrusions 33 contact the user's neck, increasing the contact area between the kneading member 31 and the user's neck, thus increasing the massage area of ​​the kneading member 31 on the user's neck. Within one rotation cycle of the support body 32, the massage protrusions 33 can contact different positions on the user's neck, providing a more comfortable massage experience.

[0067] During the rotation of the support 32 around the rotation axis 311, multiple massage protrusions 33 rotate around the rotation axis 311 and knead and massage the user's neck. The massage protrusions 33 increase the pressure of the kneading element 31 on the user's neck, providing a more comfortable massage. The increased pressure also increases the friction between the massage protrusions 33 and the user's neck, allowing the kneading element 31 to move more stably up and down the user's neck, thus enabling the neck massager 1 to move more stably up and down the user's neck. This embodiment does not limit the materials of the support 32 and the massage protrusions 33; they can be made of plastic, rubber, metal, or other materials. This embodiment also does not limit the molding method of the support 32 and the massage protrusions 33; they can be integrally molded or thermoformed, allowing the kneading element 31 to have higher structural strength and lower processing costs.

[0068] Please refer to Figure 5During the massage process of the massage protrusion 33 on the user's neck, in order to further increase the contact area between the massage protrusion 33 and the user's neck, so that the kneading member 31 can have a larger massage area on the user's neck, the inner surface 331 of each massage protrusion 33 near the rotation axis 311 has a first slope relative to the support surface 321, and the outer surface 332 of each massage protrusion 33 away from the rotation axis 311 has a second slope relative to the support surface 321, and the first slope is greater than the second slope. It is understandable that during the contact between the massage protrusion 33 and the user's neck, both the inner surface 331 and the outer surface 332 of the massage protrusion 33 can contact the user's neck. In this embodiment, by setting the first slope to be greater than the second slope, the slope of the outer surface 332 of the massage protrusion 33 is gentler than the slope of the inner surface 331, thereby increasing the contact area between the massage protrusion 33 and the user's neck. Furthermore, when the setting position of the kneading member 31 is constrained by the aforementioned constraint dimensions, during the contact between the kneading member 31 and the user's neck, the outer surface 332 of the massage protrusion 33 can have a larger contact area with the user's neck than the inner surface 331 of the massage protrusion 33. And because the first slope is greater than the second slope, the contact area between the massage protrusion 33 and the user can be further increased, making the neck massager 1 have a more comfortable massage effect.

[0069] The outer surface 332 of the massage protrusion 33 away from the rotation axis 311 is mainly used to fit against the user's neck. In this embodiment, by setting the first slope to be greater than the second slope, the massage protrusion 33 can have a larger contact area with the user, thereby increasing the friction.

[0070] Please refer to Figure 2 In some embodiments, the surface of the massage protrusion 33 is smooth, which can increase the friction between the massage protrusion 33 and the user's neck. It is understood that, as one of the mechanisms for generating friction, when the two contact surfaces are relatively clean and smooth, the friction generated between the two contact surfaces is mainly due to the adhesive effect, and the adhesive effect has a more significant impact on the friction. In this embodiment, setting the massage protrusion 33 to be smooth can increase the friction between the massage protrusion 33 and the user's neck, so that the neck massager 1 can move up and down along the user's neck more stably.

[0071] Please refer to Figure 6Furthermore, the kneading component 31 also includes a heating film 34, which is fixedly connected to the side of the support body 32 facing away from the support surface 321. The heating film 34 can heat the support body 32, which has heat conduction properties, thus allowing the massage protrusions 33 to also heat up during the massage of the user's neck. This accelerates blood circulation in the user's neck, making the kneading component 31 provide a more comfortable massage effect. The heating film 34 also promotes the secretion of sweat from the skin through the massage protrusions 33, increasing the humidity of the skin surface. This further increases the friction between the massage protrusions 33 and the user's neck during contact, allowing the neck massager 1 to more stably perform its massage function.

[0072] Please refer to Figure 5 and Figure 7 As shown, each massage protrusion 33 has multiple sequentially connected ridges 35. The connecting line between two adjacent ridges 35 is a ridge line that is recessed into the massage protrusion 33. The ridge line extends from the top 336 of the massage protrusion 33 to the support surface 321, and the distance between two adjacent ridge lines gradually increases along the extension direction of the ridge 35. The inner surface 331 and the outer surface 332 of the massage protrusion 33 are composed of multiple sequentially connected ridges 35. By utilizing the multiple ridges 35 on the surface of the massage protrusion 33, the massage protrusion 33 can have a larger contact area with the user's neck when rotating. Moreover, the presence of the ridges 35 makes the surface of the massage protrusion 33 uneven, which increases the friction between the massage protrusion 33 and the user's neck, thereby allowing the neck massager 1 to move more stably up and down along the user's neck.

[0073] Please refer to Figure 5 In some embodiments, the protrusion 35 on the surface of the massage protrusion 33 is arc-shaped and extends in the opposite direction of the rotation of the massage protrusion 33, so that the setting of the protrusion 35 is more in line with the rotation of the massage protrusion 33; or, the protrusion 35 can be a thread protruding on the surface of the massage protrusion 33. The thread applies the principle of inclined plane, and increases the friction between the surface of the massage protrusion 33 and the user's neck by increasing the additional friction between the thread and the user's neck, so that the neck massager 1 can move up and down along the user's neck more stably, which can increase the massage comfort of the neck massager 1.

[0074] It is understandable that the protruding ridge 35 is designed to contact the user's neck, and the extension direction of the protruding ridge 35 can be understood as the friction angle. That is, the massage protrusion 33 has a friction angle with the user's neck during rotation. This application does not limit the extension direction, and the size of the friction angle can also be changed accordingly. The setting of the friction angle can further increase the friction force. The ridge gradually increases, which means the friction angle gradually increases. By changing the friction angle, greater friction force is achieved. Furthermore, the setting of the protruding ridge 35 can also make the massage protrusion 33 have different massage effects, increasing the diversity of massage effects and increasing massage comfort.

[0075] Please refer to Figure 5 Furthermore, multiple massage protrusions 33 are arranged in a ring around the rotation axis 311. That is, when the support body 32 rotates around the rotation axis 311, the multiple massage protrusions 33 knead and massage the user's neck to provide a more comfortable massage experience. The massage protrusion 33 with the largest projected area on the support surface 321 is the first protrusion 333, and the massage protrusion 33 with the smallest projected area on the support surface 321 is the second protrusion 334. Along the ring direction of the multiple massage protrusions 33, the massage protrusion 33 located between the first protrusion 333 and the second protrusion 334 is the third protrusion 335. The projected areas of the first protrusion 333, the third protrusion 335, and the second protrusion 334 on the support surface 321 gradually decrease. In this embodiment, the first protrusion 333, the second protrusion 334, and the third protrusion 335 are configured to have different projected areas on the support surface 321. Since the projected areas of the first protrusion 333, the third protrusion 335, and the second protrusion 334 on the support surface 321 gradually decrease, when the multiple massage protrusions 33 rotate around the rotation axis 311, the different massage protrusions 33 have different pressing pressure and different pressing areas when they contact the user's neck. As a result, the kneading member 31 can provide the user with a varied massage experience during rotation, making the neck massager 1 have a more comfortable massage effect on the user's neck.

[0076] Alternatively, the massage protrusion 33 with the highest height relative to the support surface 321 is the first protrusion 333, the massage protrusion 33 with the lowest height relative to the support surface 321 is the second protrusion 334, and along the circumferential direction of the plurality of massage protrusions 33, the massage protrusion 33 located between the first protrusion 333 and the second protrusion 334 is the third protrusion 335, and the height of the first protrusion 333, the third protrusion 335 and the second protrusion 334 relative to the support surface 321 gradually decreases. In this embodiment, the first protrusion 333, the second protrusion 334, and the third protrusion are set to have different protrusion heights on the support surface 321. Since the protrusion heights of the first protrusion 333, the third protrusion 335, and the second protrusion 334 on the support surface 321 gradually decrease, when the multiple massage protrusions 33 rotate around the rotation axis 311, the different massage protrusions 33 have different pressing pressure and different pressing areas when they come into contact with the user's neck. As a result, the kneading member 31 can provide the user with a varied massage experience during rotation, making the neck massager 1 have a more comfortable massage effect on the user's neck.

[0077] Please refer to Figure 7 The plurality of massage protrusions 33 include at least one first protrusion 333 and a plurality of second protrusions 334. The projected area of ​​the first protrusion 333 on the support surface 321 is larger than that of the second protrusion 334 on the support surface 321, and the height of the first protrusion 333 relative to the support surface 321 is greater than that of the second protrusion 334 relative to the support surface 321. A second protrusion 334 is provided on each opposite side of each first protrusion 333. That is, the first protrusion 333 has a greater massage force and a wider massage area than the second protrusion 334. The combination of the two can enhance the user's perception of the squeezing force of the kneading component, thereby providing the user with a more obvious change in squeezing force and improving the massage effect of the kneading component.

[0078] Please refer to Figure 5 The tip 336 of the first protrusion 333 is farther away from the rotation axis 311 than the tip 336 of the second protrusion 334. It can be understood that the tip 336 of the massage protrusion 33 is used to apply pressure to the user's neck. During the kneading massage of the user's neck by the kneading member 31, the rotation of the massage protrusion 33 generates friction with the user's neck. Therefore, the two adjacent massage protrusions 33 will apply pressure to the user's neck during the rotation. In this embodiment, by setting the tip 336 of the first protrusion 333 to be farther away from the rotation axis 311 than the tip 336 of the second protrusion 334, the distribution positions of the first protrusion 333 and the second protrusion 334 are not on the same central circle. This allows the kneading member 31 to provide varying massage intensity and varying pressure to the user's neck when rotating, thereby improving the user's massage experience.

[0079] Alternatively, the outer surface 332 of the first protrusion 333 is further away from the rotation axis 311 than the outer surface 332 of the second protrusion 334. It is understood that the outer surface 332 of the massage protrusion 33 can increase the contact area between the massage protrusion 33 and the user's neck. In this embodiment, by setting the outer surface 332 of the first protrusion 333 to be further away from the rotation axis 311 than the outer surface 332 of the second protrusion 334, the contact area between the first protrusion 333 and the user's neck can be increased, thereby improving the user's massage experience.

[0080] It is understandable that, in order to ensure that the top 336 of the first protrusion 333 is further away from the rotation axis 311 than the top 336 of the second protrusion 334, and that the outer surface 332 of the first protrusion 333 is further away from the rotation axis 311 than the outer surface 332 of the second protrusion 334, the outer surface of the support 32 in this embodiment can be elliptical or olive-shaped. By setting the first protrusion 333 and the second protrusion 334 to be arranged around the support surface 321, the kneading member 31 can apply varying massage intensity and varying massage area to the user during the kneading massage process. Alternatively, the outer surface of the support 32 can be circular. By setting the distribution position of the first protrusion 333 and the second protrusion 334 on the support surface 321 to be elliptical or olive-shaped, the kneading member 31 can apply varying massage intensity to the user during the kneading massage process, and the kneading member 31 can have varying massage area with the user during the massage of the user's neck.

[0081] Please refer to Figure 5 and Figure 7 The surface of the massage protrusion 33 can be at least one of a conical surface or a spherical surface. The conical and spherical surfaces have a relatively smooth transition surface, which makes the massage protrusion 33 provide a more comfortable massage effect to the user. In addition, the conical and spherical surfaces can also increase the contact area between the massage protrusion 33 and the user's neck, thereby increasing the massage area of ​​the massage protrusion 33 on the user's neck.

[0082] The support body 32 includes a support plate 36 and a support base 37. The support plate 36 is disposed on the support base 37, and the support surface 321 is the surface of the support plate 36 facing away from the support base 37, pointing from the geometric center to the edge of the support surface 321. The support surface 321 is inclined towards the support base 37. When the conical or spherical massage protrusions 33 come into contact with the user's skin, the massage protrusions 33 compress the user's skin, resulting in a large contact area. Moreover, the inclined arrangement of the support surface 321 towards the support base 37 makes the massage protrusions 33 fit closer to the user's skin when rotating, thereby further increasing the contact area between the massage protrusions 33 and the user's skin, thus increasing the massage area of ​​the neck massager 1 on the user's neck.

[0083] When the neck massager 1 is placed around the user's neck and performs a kneading massage, the kneading element 31 may be hindered from rotating due to external forces during the rotation process. For example, when the user wears the neck massager 1 and leans against a sofa, the user's neck may obstruct the rotation of the kneading element 31, causing the two kneading elements 31 to be unable to rotate at the same time, or the rotation stroke of the two kneading elements 31 to be different.

[0084] Please refer to Figure 8 and Figure 9 To prevent the two kneading elements 31 from not performing kneading movements synchronously, the massage assembly 3 also includes a base 38, a detection element 39, and a reflector 40. The base 38 is disposed on the wearing bracket 2; the detection element 39 is disposed on the surface of the base 38 facing the support surface 321; the reflector 40 is disposed on the surface of the support 32 facing the detection element 39. The reflectivity of the reflector 40 is different from the reflectivity of the surface of the support 32 facing the detection element 39, or the reflector 40 has two reflective areas with different reflectivities. When the rotational strokes of the two kneading elements 31 differ, that is, at least one detection element 39 cannot sense the reflector 40, the detection element 39 transmits the sensing information to the controller. The controller controls the rotational speed of the two kneading elements 31, ultimately ensuring that the two kneading elements 31 have the same rotational stroke, allowing them to perform synchronous kneading massage on the user. This embodiment does not limit the specific type of the detection element 39; for example, the detection element 39 can be an infrared sensor.

[0085] Please refer to Figure 2 The massage component 3 also includes a drive unit 41 and a gearbox 42.

[0086] The driving component 41 serves as the driving component in the massage assembly 3, and is used to drive the rotation of the kneading component 31. The driving component 41 is disposed on the wearing bracket 2 and has a driving shaft 411. The driving shaft 411 can be connected to the kneading component 31 through transmission or directly connected to drive the kneading component 31 to perform kneading massage on the user's neck.

[0087] The reduction gearbox 42, serving as both a reduction and transmission component in the massage assembly 3, has a high-speed input shaft and a low-speed output shaft 421. The high-speed input shaft of the reduction gearbox 42 is connected to the drive shaft 411, and the low-speed output shaft 421 is connected to the kneading member 31. The reduction gearbox 42 can convert the high-speed output of the drive shaft 411 into a low-speed output shaft 421, allowing the kneading member 31 to have a more comfortable kneading frequency and intensity. The low-speed shaft of the reduction gearbox 42 is coaxially arranged with the rotation axis 311 to transmit power to the kneading member 31 more stably.

[0088] The wearable support 2 has a plane of symmetry S, and the two massage components 3 are arranged symmetrically about the plane of symmetry S, so that the neck massager 1 can produce a symmetrical massage effect on the user's neck. Furthermore, in the same massage component 3, the drive shaft 411 is closer to the plane of symmetry S than the output shaft 421. That is, along the length direction around the neck segment 22, the arrangement span between the two rotation axes 311 is greater than the arrangement span between the two drive shafts 411, thereby giving the two kneading parts 31 a larger arrangement span, which in turn increases the massage area of ​​the neck massager 1 on the user's neck.

[0089] It is understood that the neck massager 1 of this application embodiment has two driving members 41. Compared with the driving scheme of a single driving member 41 driving two kneading members 31, the two driving members 41 are symmetrically arranged about the symmetry plane S in this embodiment, which can reduce the thickness of the neck segment 22. Moreover, by setting the two driving members 41 on both sides of the symmetry plane S, the internal structural layout of the neck massager 1 can be planned more reasonably, so that the neck massager 1 can be made thinner.

[0090] Furthermore, since the drive shaft 411 and the kneading component 31 are connected by a reduction gearbox 42, that is, the drive shaft 411 and the rotation axis 311 in this embodiment are not coaxial. Also, since the drive shaft 411 is closer to the symmetry plane S than the output shaft 421, the massage component 3 has a larger layout span in the length direction of the wearing bracket 2, and the part of the neck wrap 22 that is away from the symmetry plane S can also have a smaller thickness.

[0091] Please refer to Figure 1 and Figure 2 The support 2 includes an elastic segment 23 and two handles 24 respectively connected to both ends of the elastic segment 23.

[0092] The elastic segment 23 can undergo elastic deformation and has the characteristic of returning to its original shape after deformation. This embodiment does not limit the composition material of the elastic segment 23. For example, the elastic segment 23 can be rubber, which has the advantages of wear resistance and high elasticity; or the elastic segment 23 can be plastic, which is lighter and has lower processing costs, thus reducing the weight and manufacturing cost of the wearable bracket 2.

[0093] When a user wears the neck massager 1, the user holds both handles 24 and gradually increases the distance between them until the distance is sufficient for the user's neck to pass through. The user then holds the handles 24 and places the neck massager 1 around their neck, ensuring the kneading element 31 fits snugly against the neck, and releases their grip on the handles 24. As the distance between the handles 24 gradually increases during wear, the elastic segment 23 undergoes elastic deformation. When the user releases their grip on the handles 24, the two handles 24 move closer together under the influence of elastic potential energy, thus placing the user's neck within the neck-wrapping space 21, thereby achieving the clamping effect of the neck massager 1 on the user's neck. It is understandable that the elastic segment 23 allows the neck massager 1 to be stably placed on the user's neck without the need for external force. That is, the user can place the neck massager 1 on their neck without the need for a pull cord, thus freeing the user's hands. Furthermore, in addition to freeing the user's hands, the neck massager 1 of this embodiment can also move up and down along the user's neck, allowing the neck massager 1 to change different massage positions during the massage process.

[0094] The handle 24 is designed for user gripping, allowing the user to wear the neck massager 1 by holding the handle 24. This embodiment does not limit the material of the handle 24; for example, the handle 24 can be made of plastic, which is lightweight and has low processing costs, thus reducing the weight and manufacturing cost of the wearing bracket 2.

[0095] When a user wears the neck massager 1, the neck massager 1 is placed around the user's neck, and the two handles 24 abut against the user's shoulders under the action of gravity, and each of the two handles 24 has abutting position on the user's shoulders. The user's shoulder provides support to the handle 24 at the contact point. At this time, without the action of external force, the neck massager 1 is subjected to the support force at the contact point, the friction between the kneading element 31 and the user's neck, and the weight of the neck massager 1 itself. Furthermore, in order to make the neck massager 1 more stably surrounding the user's neck without the action of external force, the overall center of gravity of the neck massager 1 is further away from the elastic section 23 than the contact point. That is, the overall center of gravity of the neck massager 1 is set at the front of the human body, so that the neck massager 1 has a tendency to tilt towards the front of the human body when worn. This also makes the kneading element 31 on the neck wrapping section 22 and the upper neck section have a tendency to tilt towards the front of the human body. This can increase the degree of fit between the kneading element 31 and the user's neck, increase the contact area between the kneading element 31 and the user's neck, and make the neck massager 1 move up and down more stably on the user's neck.

[0096] Please refer to Figure 1 and Figure 4The minimum distance D2 between the ends of the two handles 24 that are far from the elastic segment 23 is equal to 15mm and less than or equal to 25mm. In this embodiment, by limiting the minimum distance D2 between the two handles 24, the elastic segment 23 has a longer elastic deformation lever arm, which can obtain a larger elastic deformation range. That is, the neck-wrap space 21 has a larger elastic adjustment range. While ensuring the structural strength of the wearing bracket 2, the wearing bracket 2 can fit the user's neck more closely or adapt to different user necks.
