Description

Technical Field

[0001] This invention relates to the field of light therapy devices, specifically a fun light therapy device for myopia prevention and control. Background Technology

[0002] The light-enhancing device uses specific wavelengths of red light, mimicking sunlight, to convert light energy into light on the retina, enriching the choroidal supply, activating cell regeneration in the macular region, promoting dopamine secretion, thickening and strengthening the posterior sclera, and inhibiting abnormal axial elongation from the root, thereby effectively controlling myopia and amblyopia. Myopia and amblyopia are extremely common among adolescents in the period of visual development.

[0003] During the treatment of myopia, children need to sit quietly and look at the device for a period of time, which is a very tedious process. For active children, this process is very difficult. However, by adding interactive entertainment facilities to the device, children can sit still in front of the device for treatment. Therefore, we propose a fun myopia prevention and control phototherapy device. Summary of the Invention

[0004] One of the technical problems this application aims to solve is: how to alleviate the boredom of the treatment process through interactive entertainment without affecting the treatment itself.

[0005] To solve the above-mentioned technical problems, this application provides a fun myopia prevention and control light therapy device, which includes a light therapy device body and a base on the light therapy device body;

[0006] It also includes:

[0007] The key assembly consists of multiple keys of different shapes and is movably mounted on the main body of the light-emitting device;

[0008] The device has multiple insertion posts, each corresponding to a key of a different shape, and is located inside the main body of the light-absorbing device.

[0009] The push mechanism is provided, the displacement component is located inside the main body of the light-emitting device and has an opening on the side of the insertion post.

[0013] In some embodiments, there are multiple control components, and the position of the crossbar is different in different control components. In one control component, the transmission gear 1 is directly connected to the transmission gear 2. In another control component, the crossbar 1 is removed and the unlocking gear is set on the crossbar 2.

[0014] In some embodiments, each key in the key set has a toothed protrusion that meshes with an unlocking gear, and the key set has a handle, the shape of which varies in different key sets.

[0015] In some embodiments, the triggering component includes a connecting block, a connecting spring is provided between the connecting block and the insert, and a plurality of limiting grooves are provided on the connecting block, and the limiting hook can be embedded in the limiting grooves.

[0018] In some embodiments, the base is provided with a reward slot located below one side of the drop slot, and the base is provided with a plurality of irregularly shaped slots located above the insertion post, the shape of which is similar to that of a key handle.

[0019] In some embodiments, a limiting strip is provided inside the base, a sliding groove is provided on the connecting block, the limiting strip can be embedded in the sliding groove, and the connecting block is provided with an L-shaped structure.

[0020] The present invention has at least the following beneficial effects:

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The light-emitting device is an instrument that can be used for myopia prevention and amblyopia treatment in adolescents. It mainly uses a beam of red light (Class I laser) with a specific wavelength of 650nm that is beneficial to the human body, which is directly irradiated to the posterior pole of the fundus. This can accelerate local blood circulation in the fundus and thicken the choroid, promote the secretion of dopamine by retinal pigment epithelial cells, improve choroidal ischemia and scleral thinning in the progression of myopia, and to a certain extent help slow down the growth of the axial length of the eye, thereby achieving the goal of controlling the increase of myopia. This product ensures safety through two parameters: First, it strictly controls the laser power entering the eye. The laser device uses a Class I laser, which complies with the International Electrotechnical Commission's Class I laser standard, with a laser power of <0.4mw. The power entering the eye is below 0.39mw (the red light irradiation power received by the human eye during outdoor daytime hours ranges from 0.9-5.17MW), and will not cause damage to the fundus. Second, it uses a 1.7mw laser chip with excellent stability, eliminating sudden situations of power instability or abnormal imbalance during red light therapy, and achieving laser power adjustability so that different levels of laser power can be selected for irradiation according to the needs of myopia control.

[0040] Currently, phototherapy devices are explicitly classified as Class III medical devices. Safe and stable power and a uniform red light spot design are essential to ensure the safety of users undergoing red light therapy. Several authoritative institutions in China have also conducted clinical trials evaluating the safety of the device on the external eye and cornea during use, and no adverse reactions such as eyelid redness, photophobia, tearing, conjunctival congestion and edema, or corneal epithelial damage have been observed. It is worth mentioning that red light in the 600-640nm wavelength band has been used clinically for the treatment of amblyopia for nearly 20 years, and similarly, no adverse events have been reported.

[0041] refer to Figure 14 The laser is emitted through a laser component, and after entering the lens barrel, the laser undergoes optical path modification and diffusion, so that the emitted laser can simulate the specific wavelength of 650nm red light (Class I laser) in sunlight that is beneficial to the human body. After irradiating the posterior pole of the fundus, it helps to slow down the growth of the axial length to a certain extent, thereby achieving the purpose of controlling the increase of myopia.

[0042] refer to Figure 15 To prevent harm to users, the IEC (International Electrotechnical Commission) standard sets out safety standards for laser products. "IEC 60825-1" is the international standard for laser products and a common safety standard for IEC member countries. Based on the maximum output laser power, the IEC standard (IEC 60825-1) classifies laser products into seven levels: "CLASS 4" indicates hazards from both direct beams and radiation; "CLASS 3B" indicates hazards from direct beams; "CLASS 3R" indicates hazards from looking directly at the beam; "CLASS 2M" indicates no hazards under normal use, but the use of magnifying glasses, telescopes, and other optical equipment increases the danger; "CLASS 2" indicates safe use, but one should not intentionally look at the laser beam; "CLASS 1M" indicates no hazards under normal use, but the use of magnifying glasses, telescopes, and other optical equipment increases the danger; and "CLASS 1" indicates no hazards. The laser device uses Class I laser, conforming to the IEC Class I laser standard.

[0043] Example 1

[0044] Please see Figure 1-11 The present invention provides a technical solution: a fun myopia prevention and control light therapy device, including a light therapy device body 1, and a base 11 is provided on the light therapy device body 1;

[0045] It also includes:

[0046] Key assembly 2, which consists of multiple keys of different shapes, is movably mounted on the main body 1 of the light-emitting device;

[0047] Insertion post 3, there are multiple insertion posts 3, each corresponding to a key of a different shape, and they are set inside the main body 1 of the light-absorbing device;

[0048] The push mechanism 5 and the displacement component 5 are set inside the main body 1 of the light-emitting device, and have an opening on the side of the insertion post 3. The push mechanism 5 extends from the opening into the inside of the insertion post 3. When the key is inserted into the insertion post 3 in a corresponding manner, the push mechanism 5 is driven to move.

[0049] Storage mechanism 4 abuts against jacking mechanism 5. When jacking mechanism 5 moves, it jacks storage mechanism 4 and leaks its internal materials out.

[0050] The jacking mechanism 5 includes a control component 52 and a trigger component 51. The control component 52 includes an embedding hole 521, which restricts the movement direction of the key assembly 2 and ensures that the key assembly 2 remains vertical when falling. The key assembly 2 can pass through the surface of the insertion post 3 through the embedding hole 521. The embedding hole 521 is set on the insertion post 3. A crossbar 1 522 is rotatably arranged inside the insertion post 3. Once the crossbar 1 522 rotates, the facilities on it will rotate accordingly. A crossbar 2 523 is rotatably arranged inside the insertion post 3 below the crossbar 1 522. Once the crossbar 2 523 rotates, the facilities on it will rotate accordingly.

[0051] A first unlocking gear 524 is provided on the first crossbar 522, a first transmission gear 525 is provided on the first crossbar 522, and a second transmission gear 526 is provided on the second crossbar 523. A toothed belt 527 is provided between the first transmission gear 525 and the second transmission gear 526. Under the premise of distinguishing the height of the first crossbar 522 in different control components 52, the first transmission gear 525 and the second transmission gear 526 can rotate synchronously, thereby enabling the first crossbar 522 and the second crossbar 523 to rotate synchronously. A limit hook 528 is provided on the second crossbar 523 to restrict the connecting block 511. There are multiple limit hooks 528. After all the limit hooks 528 are released, the connecting block 511 can move.

[0052] There are multiple control components 52, and the positions of the crossbar 522 and the unlocking gear 524 are different in different control components 52. If the wrong key group 2 is inserted, the limit hook 528 will most likely not be unlocked. In one control component 52, the transmission gear 525 is directly connected to the transmission gear 526. In another control component 52, the crossbar 522 is removed, and the unlocking gear 524 is set on the crossbar 523. This saves materials while ensuring the desired effect.

[0053] Each key in key set 2 has a toothed protrusion 22, which meshes with the unlocking gear 524. The toothed protrusion 22 is located in different positions on different key sets 2, and is set according to high, medium and low positions. Since the key set 2 with the toothed protrusion 22 at the lowest end can unlock all the pins 3, while other keys cannot unlock the pins 3 that have canceled the crossbar 522. The key set 2 is provided with a key handle 21, and the key handle 21 on different key sets 2 has a different shape. The key handle 21 is used to prompt the user.

[0054] The trigger component 51 includes a connecting block 511. A connecting spring 513 is provided between the connecting block 511 and the insert 3. The connecting spring 513 provides the power for the connecting block 511 to move after it is fully unlocked. The connecting block 511 has multiple limiting slots 512. The connecting block 511 can only move after the multiple limiting slots 512 are released. The limiting hook 528 can be embedded in the limiting slots 512.

[0055] A reverse ratchet mechanism 515 is provided on the second crossbar 523. A reset gear 516 is provided on the outer ring of the reverse ratchet mechanism 515. The reset gear 516 can drive the second crossbar 523 to rotate only when it rotates in a specified direction. If it rotates in the opposite direction, it will spin freely. A rack 514 is provided on the connecting block 511. The length of the tooth marks on the rack 514 is limited. When the rack 514 reaches a certain position, the meshing between the rack 514 and the reset gear 516 is released. The reset gear 516 meshes with the rack 514. The rack 514 cooperates with the reverse ratchet mechanism 515 so that when the rack 514 moves in a specified direction, it causes the first crossbar 522 to rotate. This prevents the rack 514 from driving the first crossbar 522 to move when the connecting block 511 moves outward, which would cause interference between the unlocking gear 524 and the toothed protrusion 22.

[0056] The storage mechanism 4 includes a placement slot 41 with a hole for placing reward items. The placement slot 41 is located inside the base 11 and extends through the upper surface of the placement slot 41. A drop trough 42 is located below the placement slot 41 with an inclined bottom surface. The drop trough 42 extends through the front surface of the base 11. An isolation slot 43 is movably provided between the placement slot 41 and the drop trough 42 to prevent reward items from falling directly. The isolation slot 43 is connected to the connecting block 511.

[0057] The base 11 is provided with a reward slot 12, which is located below one side of the drop slot 42. The base 11 is provided with multiple irregular slots 13, which are located above the control component 52. The irregular slots 13 are similar in shape to the key handle 21, which determines the correspondence between different key sets 2 and the control component 52.

[0058] In use, the key set 2 is inserted into the insertion post 3 through the insertion hole 521. The insertion must correspond to the shape of the key handle 21 and the irregular groove 13. After the key set 2 is inserted, the toothed protrusion 22 drives the unlocking gear 524 to rotate, which in turn drives the first transmission gear 525 to rotate through the first transmission gear 526, causing the second transmission gear 523 to rotate. This causes the limit hook 528 to lift, unlocking the connecting block 511. The height position of the corresponding toothed protrusion 22 on different key sets 2 is different, and the position of the first transmission gear 522 in the corresponding control component 52 is different. All three key sets 2 are inserted into the corresponding insertion holes 521. After step 21, all three limit hooks 528 are raised. At this time, the connecting block 511 moves forward under the action of the connecting spring 513. The connecting block 511 aligns the hole on the isolation groove 43 with the hole on the placement groove 41, so that the reward item can successfully fall into the drop groove 42 and then roll into the reward groove 12. During the forward movement of the connecting block 511, the reset gear 516 rotates freely. During the process of pulling out the key group 2, the internal rotating structure reverses. The reverse rotation of the crossbar 2 523 drives the reset gear 516 to rotate. The rack 514 meshing with the reset gear 516 drives the connecting block 511 to move backward, completing the equipment reset.

[0059] Example 2

[0060] Please see Figure 12-13 The present invention provides a technical solution: a fun myopia prevention and control light therapy device, and embodiment 2 is an optimization based on embodiment 1;

[0061] A limiting strip 6 is provided inside the base 11, and a sliding groove 61 is provided on the connecting block 511. The limiting strip 6 can be embedded in the sliding groove 61. The connecting block 511 is designed with an L-shaped structure. By designing the connecting block 511 with an L-shaped structure, the weight of the connecting block 511 can be effectively reduced, which facilitates the movement of the connecting block 511. The limiting strip 6, together with the sliding groove 61, limits the direction of movement of the connecting block 511.

[0062] In use, the key set 2 is inserted into the insertion post 3 through the insertion hole 521. The insertion must correspond to the shape of the key handle 21 and the irregular groove 13. After the key set 2 is inserted, the toothed protrusion 22 drives the unlocking gear 524 to rotate, which in turn drives the first transmission gear 525 to rotate through the first transmission gear 526, causing the second transmission gear 523 to rotate. This causes the limit hook 528 to lift, unlocking the connecting block 511. The height position of the corresponding toothed protrusion 22 on different key sets 2 is different, and the position of the first transmission gear 522 in the corresponding control component 52 is different. All three key sets 2 are inserted into the corresponding insertion holes 521. After step 21, all three limit hooks 528 are raised. At this time, the connecting block 511 moves forward under the action of the connecting spring 513. The connecting block 511 aligns the hole on the isolation groove 43 with the hole on the placement groove 41, so that the reward item can successfully fall into the drop groove 42 and then roll into the reward groove 12. During the forward movement of the connecting block 511, the reset gear 516 rotates freely. During the process of pulling out the key group 2, the internal rotating structure reverses. The reverse rotation of the crossbar 2 523 drives the reset gear 516 to rotate. The rack 514 meshing with the reset gear 516 drives the connecting block 511 to move backward, completing the equipment reset.

[0063] By setting the connecting block 511 as an L-shaped structure, the weight of the connecting block 511 can be effectively reduced, which facilitates the movement of the connecting block 511. The limiting strip 6, together with the slide groove 61, limits the movement direction of the connecting block 511.
