Abstract
Description
Technical Field
[0001] This invention relates to the field of therapeutic device structures, and more particularly to an eye therapeutic device. Background Technology
[0002] Eye therapy devices, especially those emitting infrared light towards the eyes or surrounding area, typically include a cylindrical structure housing the infrared emission module and a facial contact structure for fitting and positioning against the user's face. During use, the facial contact structure needs to adhere to the user's skin around the eye socket under a certain pressure to ensure the relative stability of the infrared light irradiation position and effective alignment during treatment.
[0003] However, the skin and underlying soft tissue in the eye area are soft, deformable, and have a high coefficient of friction. This area also contains a large number of sensory nerves, making it particularly sensitive to lateral traction and shearing. During the wearing and use of the eye therapy device, a relative displacement tendency inevitably occurs between the device and the face. For example, slight head rotations, changes in facial expressions, gravity, and slow changes in soft tissue during prolonged use can cause minute lateral or combined displacements between the device and the face.
[0004] In existing eye therapy devices, the barrel of the infrared emission module is typically fixed to the shell or facial contact structure using a rigid or semi-rigid connection. When the barrel tends to shift relative to the face, this displacement easily translates into shearing force at the facial contact interface, causing the skin to experience dragging force. This shearing force not only easily causes user discomfort, indentations, erythema, or itching, but also amplifies these adverse sensations over a long period, reducing user willingness to wear the device and usage compliance. Furthermore, the shearing force can cause the facial contact structure to slowly creep at the contact interface, gradually deviating the actual position of the barrel relative to the eye from its initial alignment, thus affecting the consistency and stability of the infrared irradiation area. For eye therapy scenarios requiring a relatively fixed irradiation position for a certain period, this creeping phenomenon reduces treatment repeatability and the reliability of the effect. In some devices with contact detection or pressure detection structures, shear-induced changes in contact state may also cause fluctuations or misjudgments in the detection signal.
[0005] In some existing solutions, comfort is often improved by increasing the softness of the facial contact pad. However, this method mainly buffers normal pressure and cannot effectively eliminate shear forces caused by lateral or combined directional displacement. In fact, it may exacerbate positional drift problems as the entire soft pad is dragged across the skin surface. Therefore, relying solely on soft materials is insufficient to solve the shear force problem generated during actual use of eye therapy devices. Summary of the Invention
[0006] This invention discloses a glasses therapy device, which aims to solve the problem in the prior art that the facial contact interface generates shear force due to the user's slight head movements, causing discomfort and affecting the treatment effect.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An eye treatment device, comprising: Outer cover; An infrared therapy component is disposed within the outer casing. The infrared therapy component includes a module housing, a cylinder and an infrared emission module installed within the module housing, the infrared emission module being used to generate infrared light, and the infrared light being emitted through the cylinder. A panel connected to the outer cover, the panel having a viewing window structure for the user's eye alignment; It also includes a shear force reduction component, which is disposed on the force transmission path between the infrared therapy component and the user's face. When the window structure and the user's face tend to move relative to each other, the shear force generated on the user's face is reduced by generating adaptive deformation or relative movement.
[0008] Furthermore, the shear force reduction component is a compensation component connecting the cylinder and the module housing, and the compensation component is used to enable the cylinder to move relative to the module housing within a preset degree of freedom.
[0009] Furthermore, the compensation component is a rotation compensation component, which enables the cylinder to rotate around a vertically arranged axis or swing within a limited angle range.
[0010] Furthermore, the rotation compensation component includes: The inner ring is fixed to the cylinder body; The outer ring fixed to the module housing; and A pivot connecting the inner ring and the outer ring allows the inner ring to rotate relative to the outer ring.
[0011] Furthermore, the compensation component is a translational compensation component, which enables the cylinder to perform translational movement in the radial direction; The translational compensation component includes: a slider fixed to the cylinder; and A slide rail fixed to the module housing and slidingly engaged with the slider.
[0012] Furthermore, the window structure includes a connector fixed to the panel and a window tube passing through the connector; the tube is fixedly connected to the window tube; the connector has a through hole for the window tube to pass through, the diameter of which is larger than the outer diameter of the window tube, thus reserving clearance for the movement of the tube.
[0013] Furthermore, the shear force reduction component is a flexible contact portion disposed on the user-facing side of the window structure; the flexible contact portion includes a faceplate and multiple independent flexible contact units disposed on the faceplate; When the user's face comes into contact with the flexible contact portion, the multiple flexible contact units respectively form local contact with the user's face and undergo independent flexible deformation or displacement when shear force is generated.
[0014] Furthermore, the contact end shape of the flexible contact unit is a spherical head, a hemispherical head, a rounded corner protrusion, or a truncated cone head structure; and / or the flexible contact units are distributed in a ring array along the circumference of the window structure.
[0015] Furthermore, the window structure includes a face ring that contacts the user's face and a base ring connected to the panel; the shear force reduction component is a flexible shear layer connecting the face ring and the base ring; The flexible shear layer has shear deformation capability in a direction perpendicular to the cylinder axis, and is used to absorb the lateral displacement of the facing ring relative to the base ring.
[0016] Furthermore, the flexible shear layer is a thin-walled corrugated tube structure or a wrinkled film structure.
[0017] Compared with the prior art, the beneficial effects of the present invention include: 1. By introducing four different forms of shear force reduction components, whether through the rotation or translation of the cylinder or through the deformation of the contact interface, the shear force generated by the unconscious movement of the user's head can be effectively absorbed or compensated, fundamentally solving the problem of rigid drag between the device and facial skin in the existing technology and eliminating discomfort.
[0018] 2. The infrared light emitting core component moves synchronously with the head, ensuring the beam is always precisely aligned with the target area of the eye. A stable contact surface also avoids alignment deviations caused by contact ring creep due to shear forces. Both of these methods guarantee the stability and uniformity of treatment energy delivery, thereby improving treatment efficacy.
[0019] 3. The different solutions of this invention can better adapt to the facial features of different users, such as facial asymmetry, facial wrinkles, or beards. Improved comfort will enhance users' willingness to continue using the product, which is especially important for eye therapy that requires long-term adherence. Attached Figure Description

[0027] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.
[0028] This invention discloses an eye therapy device, whose basic structure is based on existing technology, including an outer casing 10 for housing all internal components. An infrared therapy component, the core of the therapy function, is installed inside the outer casing 10. This component includes at least an infrared emission module (e.g., an infrared LED array, laser diode, etc.) that generates infrared light and is electrically connected to the power supply of the therapy device, and a cylindrical body 22 for guiding the light. These components are integrated within one or more module housings 21 for easy assembly and positioning. On the user-facing side of the outer casing 10, a detachable panel 11 is provided. Through holes are provided on the panel 11 for mounting a viewing window structure. This viewing window structure fits snugly against the user's eye socket area during use, ensuring accurate light illumination of the eyes. To assist the user in stabilizing their head posture, the device is typically used with a headrest (not shown). This headrest can be integrally formed with the panel 11 or placed as a separate accessory on a table, primarily providing Z-axis (vertical) support for the user's head.
[0029] The core improvement of this invention lies in the design of a shear force reduction component, which aims to solve the problem of shear force between the viewing window and facial skin caused by slight head movements of the user. The following details different implementations of this component through several embodiments.
[0030] Example 1 This embodiment provides a shear force reduction scheme based on rotational compensation. In this scheme, the shear force reduction component is a rotational compensation component, which allows the cylinder 22 housing the infrared emission module to rotate relative to the module housing 21 fixed to the outer cover 10.
[0031] Specifically, an inner ring 231 is fixedly connected to the outer wall of the middle section of the cylinder 22. The module housing 21 consists of two housing parts that can be interlocked or connected by threaded fasteners, and a mounting base 233 is provided inside the housing part. An outer ring 232 is fixed on the mounting base 233. The inner ring 231 is placed inside the outer ring 232 and is rotatably connected by rotating shafts located at the upper and lower ends. When the module housing 21 is partially closed, the mounting base 233 is clamped and fixed, thereby providing a stable reference for the rotation of the cylinder 22.
[0032] The viewing window structure includes a connector 32 and a viewing window tube 31. The connector 32 is fixed to the panel 11 by screws or other fasteners. One end of the viewing window tube 31 is fixedly connected to the front end of the tube body 22, and the other end passes through the connector 32. Crucially, the connector 32 has a through hole for the viewing window tube 31, the inner diameter of which is larger than the outer diameter of the viewing window tube 31, thus forming an annular gap.
[0033] The working principle is as follows: The user places their chin on the headrest, with their eye sockets against the end of the viewing window tube 31. When the user's head unconsciously turns left or right, the facial skin will cause the viewing window tube 31 to rotate in the same direction. Since the tube body 22 and the viewing window tube 31 are rigidly connected, and the tube body 22 can rotate freely through the rotation compensation component, the tube body 22 will compliantly rotate with the head. This rotation occurs between the tube body 22 and the module housing 21, while the contact interface between the viewing window tube 31 and the user's face has almost no relative sliding. Therefore, shear force is effectively eliminated. The reserved annular gap ensures that the viewing window tube 31 will not interfere with the fixed connector 32 during rotation. The inner ring 231 and the outer ring 232 can rotate freely 360 degrees, or they can be limited to a swing range of, for example, ±15° by setting a limit block, which is sufficient to cope with most unconscious head deflections. Since the infrared emission module is installed inside the tube body 22, it rotates synchronously with the tube body 22, always maintaining precise alignment with the eyeball. For users with asymmetrical eyes, the independent rotation capability of the two cylinders 22 can also play a passive compensation role.
[0034] Example 2 This embodiment provides a translational compensation shear force reduction scheme. The shear force reduction component is embodied as a translational compensation component, which allows the cylinder 22 to slide linearly within a small range along its radial direction (horizontal left and right direction).
[0035] Specifically, one or more sliders 241 are fixedly mounted on the top and / or bottom surfaces of the cylinder 22. Correspondingly, slide rails 242 that precisely mate with the sliders 241 are machined or mounted on the inner top and / or bottom surfaces of the module housing 21. The sliders 241 can slide smoothly within the slide rails 242. The configuration of the viewing window structure is similar to that of Embodiment 1, also utilizing the through-hole on the connector 32 to provide space for the movement of the viewing window cylinder 31.
[0036] The working principle is as follows: When the user's head moves slightly left or right or tilts to the side, the face pushes the viewing window tube 31 to move to the side. Since the tube 22 can move horizontally through the sliding structure, it will adaptively follow the face. This displacement is absorbed by the translational compensation component, thereby avoiding the formation of shear force on the face contact interface. The sliding stroke can be designed to be very small, for example, ±3mm. This is not for a wide range of interpupillary distance adjustment, but purely to reduce the shearing effect caused by minor adjustments in head posture. To further improve the experience, a low-friction coefficient coating, such as a polytetrafluoroethylene (PTFE) coating, can be applied to the contact surfaces of the slider 241 and the slide rail 242 to greatly reduce sliding damping, making the following movement of the tube 22 more sensitive and smooth, with the user hardly feeling any resistance.
[0037] Example 3 This embodiment provides a shear force reduction scheme with localized flexible contact. In this scheme, the cylinder 22 and the module housing 21 can be rigidly fixed, and the shear force reduction occurs at the contact point between the window structure and the face.
[0038] Specifically, the window structure includes a window tube 31 and a connector 32, both of which are fixed to the panel 11. A flexible contact portion is provided at the end of the window tube 31 closest to the user, including an annular adhesive base 252 fixed to the connector 32. Multiple independent flexible contact units 251 are arranged on the adhesive base 252. The flexible contact unit 251 can be a flexible protrusion made of soft materials such as silicone or thermoplastic elastomer (TPE). The root of each protrusion is connected to the adhesive base 252, while its head is used for skin contact.
[0039] To optimize tactile feedback and deformability, the protruding heads can be designed with smooth geometric shapes, such as spherical heads, hemispherical heads, or truncated cone heads with large rounded corners, to form point contact or small-area contact, avoiding the line pressure of traditional annular edge contact. These flexible contact units 251 can be uniformly or non-uniformly distributed in a ring along the circumference of the face base 252. For example, based on the distribution of bones and soft tissues in the eye socket region of the human face, protrusions with slightly higher hardness or larger size can be arranged above and below (corresponding to the brow bone and cheekbone), while softer and smaller protrusions can be arranged at the inner and outer corners of the eyes.
[0040] The working principle is as follows: When the user's head tends to rotate or translate, the overall shear force is distributed to each individual flexible contact unit 251. Each unit undergoes independent, minute tilting, oscillation, or compression deformation based on the local force acting on its location. This transforms a concentrated interfacial shear force into dispersed localized compliant deformation. The overall dragging sensation felt by the user's facial skin is significantly reduced, greatly minimizing the risk of forming a circular indentation. In particular, this solution is more adaptable to complex facial features such as beards and crow's feet.
[0041] Example 4 This embodiment provides a solution based on a flexible shear layer. Similar to Embodiment 3, shear force absorption also occurs within the window structure itself, but in a different form.
[0042] Specifically, the original viewing window tube 31 is divided into two parts, forming a face-fitting ring 31a that directly contacts the face and a base ring 31b that is fixedly connected to the connector 32. The shear force reduction component is the flexible shear layer 261 that connects these two rings. The flexible shear layer 261 is designed to have high stiffness in the axial (normal) direction to provide stable support, but is very compliant in the radial (lateral) direction and is prone to shear deformation.
[0043] The flexible shear layer 261 can be implemented using various structures. For example, it can be a thin-walled, annular corrugated structure; it can be a flexible film with pre-set folds; or other designed structures.
[0044] The working principle is as follows: When the user's head tends to shift laterally, this force acts on the face-fitting ring 31a. Due to the presence of the flexible shear layer 261, the face-fitting ring 31a will translate relative to the base ring 31b, and the displacement is absorbed by the shear deformation of the flexible shear layer 261, effectively isolating lateral vibration and displacement. The shear force is dissipated within the flexible shear layer 261 and will not be transmitted to the user's facial skin. Thus, while providing stable support, it achieves excellent shear force reduction, ensuring consistent irradiation alignment and high user comfort.
[0045] A silicone layer is provided on the edge of the viewing window tube 31 that contacts the face to improve user comfort.
[0046] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
