Description

Technical Field

[0001] This invention relates to the field of eye care technology, and in particular to a portable eye care device. Background Technology

[0002] Existing eye steam treatment devices typically relieve eye fatigue and dry eye by generating warm steam. However, when using these devices, the steam often acts directly and concentratedly on the eyes. For users with sensitive corneal nerve endings, the strong initial steam stimulation can easily trigger involuntary blinking reflex (corneal reflex), tension, and discomfort, making it difficult for users to persist with the treatment and affecting the treatment effect and experience. Summary of the Invention

[0003] To overcome the shortcomings of existing eye steam care devices, where steam often acts directly and concentrated on the eyes, causing strong initial steam stimulation that can easily trigger involuntary blinking reflex (corneal reflex), tension, and discomfort for users with sensitive corneal nerve endings, making it difficult for users to persist with treatment and affecting the care effect and experience, this invention provides a portable eye care device.

[0004] The technical solution is as follows: A portable eye care device includes a three-way tube and two connecting tubes connected to both ends of the three-way tube; each of the two connecting tubes is connected to a cylindrical body; a strap connects the two cylindrical bodies together; it also includes a multi-groove disc 1; a multi-groove disc 1 is fixedly connected to each of the two cylindrical bodies; a multi-groove disc 2 is rotatably connected to each of the two cylindrical bodies; each multi-groove disc 1 is in contact with a multi-groove disc 2; a rotating ring 1 is rotatably connected to each of the two cylindrical bodies; through grooves are opened at the upper and lower parts of both cylindrical bodies; each multi-groove disc 2 has a protrusion at the upper and lower parts, and each protrusion of multi-groove disc 2 is located in the through groove of the cylindrical body. After penetrating the cylindrical body, the protrusion of multi-groove disc 2 is fixedly connected to the rotating ring 1; a number of through grooves are equidistantly opened in an annular pattern on both multi-groove disc 1 and multi-groove disc 2.

[0005] As an improvement to the above solution, both connecting pipes are connected to the tee pipe in a damped sliding connection.

[0006] As an improvement to the above solution, the straps are made of elastic nylon braided material.

[0007] As an improvement to the above solution, a silicone ring fixed to the front of the cylinder is also included.

[0008] As an improvement to the above solution, the front part of the silicone ring is set to be arc-shaped.

[0009] As an improvement to the above scheme, it also includes a multi-groove disc three rotatably connected to the cylinder body, the multi-groove disc three having several through grooves equidistantly spaced in an annular shape; a rotating ring two is rotatably connected to the outside of each of the two cylinder bodies; each multi-groove disc three has a protrusion at its upper and lower parts, and each protrusion of the multi-groove disc three is located in the through groove of the cylinder body, and the protrusion of the multi-groove disc three is fixedly connected to the rotating ring two after penetrating the cylinder body; each multi-groove disc three is in contact with a multi-groove disc two.

[0010] As an improvement to the above scheme, anti-slip grooves are opened on the outer ring surfaces of both rotating ring one and rotating ring two.

[0011] As an improvement to the above scheme, it also includes a mounting ring fixed to the outer annular surface of the cylinder; a torsion spring is fixed between the side of each rotating ring one away from the rotating ring two and the corresponding mounting ring; a friction ring plate is fixed to the side of each rotating ring one away from the rotating ring two; each friction ring plate is in contact with the corresponding outer annular surface of the cylinder.

[0012] As an improvement to the above solution, a baffle is fixed to the mounting ring to block the torsion spring.

[0013] As an improvement to the above scheme, it also includes heat-conducting plates; several heat-conducting plates are fixedly connected in an annular shape at equal intervals on each cylinder, and the friction ring is made of a base polymer (such as phenolic resin or rubber); the heat-conducting plates are in contact with the friction ring, and the heat-conducting plates are used to transfer the heat of the hot steam to the friction ring.

[0014] Beneficial effects: 1. This invention blows steam sequentially through a three-way pipe, connecting pipe, cylinder and silicone ring towards the user's eyes to care for the user's eyes; a multi-groove disc is set in the cylinder, and the spray is divided and diffused by a pair of multi-groove discs, so that the steam pressure blown towards the eyes is low and the distribution is more uniform.

[0015] 2. This invention allows the through grooves of the second multi-groove disc to gradually overlap with the through grooves of the first multi-groove disc, so that the spray is gradually blown toward the user's eyes, and the mist gradually increases in intensity, giving the nerves a gentle adaptation signal. The brain will judge it as "harmless", thus relaxing the whole body and accepting the spray calmly. Attached Figure Description

Detailed Implementation

[0022] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0023] Example 1: A portable eye care device, such as Figures 1-4 As shown, it includes a three-way pipe 1, a connecting pipe 2, a cylindrical body 3, and a strap 4; each end of the three-way pipe 1 is connected to a connecting pipe 2, and the two connecting pipes 2 are arranged symmetrically; each of the two connecting pipes 2 is connected to a cylindrical body 3; the two cylindrical bodies 3 are connected together by a strap 4.

[0024] It also includes a multi-groove disc 5, a multi-groove disc 6, and a rotating ring 7; a multi-groove disc 5 is fixedly connected inside each of the two cylinders 3; a multi-groove disc 6 is rotatably connected inside each of the two cylinders 3; each multi-groove disc 5 is in contact with a multi-groove disc 6; a rotating ring 7 is rotatably connected to the outside of each of the two cylinders 3; through grooves are opened at the upper and lower parts of the two cylinders 3; each multi-groove disc 6 has a protrusion at the upper and lower parts, and each protrusion of the multi-groove disc 6 is located in the through groove of the cylinder 3. After the protrusion of the multi-groove disc 6 passes through the cylinder 3, it is fixedly connected to the rotating ring 7. Several through grooves are opened equidistantly in an annular shape on both the multi-groove disc 5 and the multi-groove disc 6.

[0025] In order to adjust the distance between the two cylinders 3, both connecting pipes 2 are connected to the three-way pipe 1 in a damped sliding manner, and damping pads are provided between the two connecting pipes 2 and the three-way pipe 1.

[0026] To improve user comfort, the strap 4 is made of elastic nylon braided material.

[0027] It also includes a silicone ring 8; the front of the two cylinders 3 are fixed with silicone rings 8.

[0028] To improve user comfort, the front of the silicone ring 8 is designed to be curved.

[0029] It also includes a multi-grooved disc 3 9 and a rotating ring 2 10; a multi-grooved disc 3 9 is rotatably connected inside each of the two cylinders 3, and a number of through grooves are equidistantly opened on the multi-grooved disc 3 9 in an annular shape; a rotating ring 2 10 is rotatably connected outside each of the two cylinders 3; each multi-grooved disc 3 9 has a protrusion at the upper and lower parts, and each protrusion of the multi-grooved disc 3 9 is located in the through groove of the cylinder 3, and the protrusion of the multi-grooved disc 3 9 is fixed to the rotating ring 2 10 after passing through the cylinder 3; each multi-grooved disc 3 9 is in contact with a multi-grooved disc 2 6.

[0030] To facilitate manual rotation of rotating ring 7 and rotating ring 10, anti-slip grooves are provided on the outer ring surfaces of both rotating ring 7 and rotating ring 10.

[0031] In use, the device is worn around the eyes via the strap 4. The two cylinders 3 are attached to the outer periphery of the user's eyes via silicone rings 8, ensuring the cylinders 3 are aligned with the user's eyes. The soft silicone rings 8 provide added comfort. Additionally, both connecting tubes 2 are connected to the three-way tube 1 via a damping sliding mechanism. The depth of the connecting tubes 2 inserted into the three-way tube 1 can be pre-adjusted, thereby adjusting the distance between the two cylinders 3 to match the distance between the user's eyes. This ensures the cylinders 3 are directly facing the user's eyes, facilitating direct spraying and maximizing the therapeutic effect. After wearing the device, the three-way tube 1 is connected to the external steam generator via a flexible hose. Activating the steam generator releases steam sequentially through the three-way tube 1, connecting tubes 2, cylinders 3, and silicone rings 8, delivering it to the user's eyes for treatment. The cylinders 3 contain a multi-grooved disc 5, which distributes and diffuses the spray, resulting in lower steam pressure and more even distribution at the eyes.

[0032] Some users have particularly sensitive nerve endings in their cornea (the black part of the eye). Initially exposing their eyes to a large amount of mist can trigger a strong blinking reflex (known as the "corneal reflex"), fear, and discomfort. Therefore, these users can manually rotate the rotating ring 7 beforehand. Rotating ring 7 drives the multi-groove disc 6 to rotate, causing the grooves of multi-groove disc 6 to be misaligned with those of multi-groove disc 5. This means that multi-groove discs 5 and 6 together completely block the spray. Then, slowly rotate the rotating ring 7, causing multi-groove disc 6 to rotate slowly, gradually aligning the grooves of multi-groove disc 6 with those of multi-groove disc 5. This allows the mist to gradually reach the user's eyes, increasing in intensity and gradually providing a gentle adaptation signal to the nerves. The brain will interpret this as "harmless," allowing the user to relax and accept the mist.

[0033] When a user no longer wants a particular eye to receive spray treatment, the user can manually rotate the corresponding rotating ring 2 10. Rotating ring 2 10 drives the multi-groove disc 3 9 to rotate, causing the through groove on multi-groove disc 3 9 to be misaligned with the through groove on multi-groove disc 2 6. In this way, multi-groove disc 2 6 and multi-groove disc 3 9 together completely block the spray, thereby pausing the spray treatment.

[0034] Example 2: Based on Example 1, as follows Figures 1-4 As shown, it also includes a mounting ring 21, a torsion spring 22, and a friction ring plate 23; a mounting ring 21 is fixedly connected to the outer ring surface of each of the two cylinders 3; a torsion spring 22 is fixedly connected between the side of each rotating ring 1 7 away from the rotating ring 2 10 and the corresponding mounting ring 21; a friction ring plate 23 is fixedly connected to the side of each rotating ring 1 7 away from the rotating ring 2 10; each friction ring plate 23 is in contact with the corresponding outer ring surface of the cylinder 3.

[0035] To prevent users from accidentally activating the torsion spring 22, a baffle is welded onto the mounting ring 21 to block the torsion spring 22.

[0036] It also includes heat-conducting plates 24; several heat-conducting plates 24 are fixedly connected in an annular shape at equal intervals on each cylinder 3, and the friction ring plate 23 is made of a basic polymer (such as phenolic resin or rubber) with a temperature Tg≈40°C (Tg, the full name is glass transition temperature, to make the working temperature of the friction ring plate 23 exceed its Tg, so that the material will change from a hard "glassy state" to a soft and sticky "high elastic state", thereby increasing the coefficient of friction); the heat-conducting plates 24 are in contact with the friction ring plate 23.

[0037] The user slowly rotates the rotating ring 7, causing the multi-groove disc 6 to rotate slowly, gradually aligning the grooves of the multi-groove disc 6 with those of the multi-groove disc 5. This allows the spray to gradually reach the user's eyes. Precise control of the force is required to gradually increase the spray intensity, making the operation quite difficult. Therefore, an installation ring 21, a torsion spring 22, and a friction ring 23 are included. Initially, the grooves of the multi-groove disc 5 and the multi-groove disc 6 are aligned. During spray application, the user manually rotates the rotating ring 7 to displace the grooves of the multi-groove disc 6 with those of the multi-groove disc 5. When disc 2 and 6 completely block the spray, the external steam generator is activated to introduce spray into the cylinder 3. When rotating ring 1 and 7 rotate, they will drive friction ring 23 to rotate together. Rotating ring 1 and 7 will also twist torsion spring 22, causing torsion spring 22 to store force. Then the user can release rotating ring 1 and 7. Under the elastic force of torsion spring 22, friction ring 23, rotating ring 1 and multi-groove disc 2 and 6 will rotate back to their original positions. When friction ring 23 rotates, it needs to overcome the friction between itself and cylinder 3. This causes rotating ring 1 and multi-groove disc 2 and 6 to slowly rotate back to their original positions. This automatically allows the groove of multi-groove disc 2 and 5 to gradually overlap, so that the spray gradually increases from nothing to something and from weak to strong and blows towards the user's eyes.

[0038] To further promote blood circulation in the eyes and relieve eye fatigue, users can control the hot spray function of the external steamer to spray a warm mist into the eyes. The temperature of the surface of the human eye is approximately 34-35°C. Maintaining the steam temperature at 40-42°C provides a warm and comfortable sensation, achieving a heat therapy effect, while ensuring that the temperature difference with the eye surface is not too great to cause heat stress damage. Increasing the spray temperature would also increase the irritation to the user's eyes; therefore, it is necessary to slow down the speed at which the spray is directed towards the user's eyes to reduce irritation. Therefore, a heat-conducting plate 24 is provided. The user manually rotates the rotating ring 7 to offset the grooves of the multi-groove disc 6 from those of the multi-groove disc 5, effectively blocking the spray through both discs. Then, after activating the external steam generator to introduce the spray into the cylinder 3, the hot spray heats the heat-conducting plate 24. The heat-conducting plate 24 transfers heat to the friction ring 23, causing the operating temperature of the friction ring 23 to exceed its Tg value (Tg is the glass transition temperature, approximately 40°C). Similarly, the friction ring 23, made of a basic polymer (such as phenolic resin or rubber), softens and becomes more viscous, thereby increasing the friction coefficient and the frictional force between the friction ring 23 and the cylinder 3. As the friction ring 23 rotates, it must overcome this increased frictional force, causing the rotating ring 7 and the multi-groove disc 6 to rotate and reset more slowly, reducing the speed at which the spray reaches the user's eyes and lessening eye irritation. Specifically, this design increases the friction coefficient of the friction ring 23 at a working temperature of 40-42°C by approximately 2-3 times compared to room temperature (25°C). This change directly delays the reset time of the rotating ring 7 by 1-3 seconds, achieving smooth and gentle control of the spray speed and greatly improving the user experience.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
