Description

Technical Field

[0001] This invention specifically relates to a humidification chamber mirror that prevents lens fogging. Background Technology

[0002] Moisture chamber glasses are primarily used to moisturize the eyes of patients with dry eye syndrome. By creating a relatively sealed, moist space between the lens and the eye surface, they reduce tear evaporation and relieve dryness and discomfort. To improve the user experience, most current moisture chamber glasses use anti-fog coatings or anti-fog substrates for the lenses, which delays fogging to some extent. However, in actual use, when worn for extended periods, in environments with significant temperature differences, or when the body produces a lot of moisture, the humidity in the sealed space continues to rise. Water vapor can still easily condense into fog on the inside of the lens, leading to blurred vision and affecting normal vision and safety during activities.

[0003] To solve the fogging problem, traditional methods often use heated lenses for defogging. This involves placing heating wires and temperature control circuits inside or around the lens to raise its temperature and prevent water vapor from condensing. For example, Chinese invention patent CN113350027B provides an anti-fogging wet chamber mirror. The mirror body has a heating component that heats the lens to a first temperature, while the cavity of the heating component heats to a second temperature. The first temperature is heated before the second temperature, and the difference between the two temperatures is 5-20 degrees Celsius. By controlling the lens temperature and the cavity temperature, anti-fogging is achieved. This method has a simpler structure and better anti-fogging effect.

[0004] However, while traditional heated defogging methods offer some anti-fogging effect, they significantly increase the overall structural complexity and production cost of the wet chamber mirror, resulting in high product prices. Furthermore, heated defogging relies on temperature conduction and equilibrium, requiring a considerable amount of time to achieve effective anti-fogging after activation. It cannot quickly eliminate fog after it forms, often requiring users to wait a moment for clear vision to return, leading to poor usability. Therefore, this paper proposes a wet chamber mirror with anti-fogging technology to address these issues. Summary of the Invention

[0005] Therefore, it is necessary to address the problem that existing wet room mirrors, although protected with anti-fog lenses, are still prone to fogging after prolonged use. Traditional anti-fogging methods mostly involve heating the lenses, which not only makes wet room mirrors expensive but also results in long defogging times, preventing users from quickly moving their field of vision. Therefore, it is necessary to provide a wet room mirror that prevents lens fogging.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wet room mirror that prevents lens fogging, comprising: An outer frame, on which two sets of lenses and two sets of inner frames are provided, and a sealing gasket is provided on one side of the inner frame; A mounting shell is disposed at the end of the inner frame and communicates with the cavity formed between the outer frame and the inner frame. A temple is hinged to one end of the mounting shell. The defogging cotton strip is height-adjustable and is installed in the cavity, abutting against the lens; A knob, rotatably mounted on one side of the mounting housing, is connected to the defogger strip via a drive unit to convert a single rotation of the knob into driving the defogger strip to descend and then, after it reaches its lowest point, driving the defogger strip to rise. A drainage mechanism is located at the bottom of the cavity to open after the defogger strip descends and to close after the defogger strip rises.

[0007] In one embodiment, the driving unit includes: The mounting rod is height-adjustable and is installed in the cavity formed between the outer frame and the inner frame, and the defogging cotton strip is located on one side of the mounting rod; The drive rod is hinged to the mounting rod at one end, and limit posts are provided on both sides of the other end. A sliding groove is provided on the inner side of the mounting shell, and a set of the limit posts are slidably and rotatably locked in the sliding groove. A linkage mechanism is provided on the knob and connected to the other set of limiting posts to convert the single rotation of the knob into driving the limiting posts to perform a single reciprocating slide.

[0008] In one embodiment, the linkage mechanism includes: The drive disk is rotatably disposed within the mounting housing; A first control component is disposed on the knob and intermittently connected to the drive disk to convert the rotation of the knob into the rotation of the drive disk; and A second control component is disposed on the drive disk and connected to the limiting post to convert the rotation of the drive disk into driving the sliding of the limiting post.

[0009] In one embodiment, the first control component includes: The first gear is located on the knob and has a notch. The second gear is disposed on one side of the drive disc and can mesh with the first gear; A ratchet is fixedly mounted on the first gear, and the mounting housing is further provided with a pawl hinged by a torsion spring, the pawl being engaged with the ratchet; and A constant force spring is connected at one end to the shaft of the second gear and at the other end to the mounting housing.

[0010] In one embodiment, the number of teeth of the first gear is half the number of teeth of the second gear.

[0011] In one embodiment, the second control component includes: A drive frame is slidably engaged within the mounting housing along the extension direction of the slide groove, and a limiting post is rotatably disposed at the end of the drive frame; and The drive column is eccentrically positioned on one side of the drive disk and is slidably engaged within the drive frame.

[0012] In one embodiment, the mounting rod is connected to the defogging strip via a compression assembly, which compresses the defogging strip when the mounting rod is lowered to its lowest position.

[0013] In one embodiment, the extrusion assembly includes: A receiving rod has a mounting post on one side, the mounting post being slidably inserted through the mounting rod along its axis, and the defogging cotton strip is disposed on one side of the receiving rod; A first elastic element is disposed between the receiving rod and the mounting rod; Abutment block is disposed on one side of the inner frame; and A first wedge block is disposed at the end of the receiving rod, and the inclined surface of the first wedge block can abut against the abutment block after the receiving rod is lowered.

[0014] In one embodiment, the drainage mechanism includes: An installation frame is set inside the outer frame and communicates with the outside. An absorbent cotton block is set inside the installation frame. A slidable enclosure plate is mounted on the outer frame and covers the top opening of the mounting frame; and An opening component is disposed on the closure plate and connected to the mounting rod, so as to drive the closure plate to slide open after the mounting rod is lowered, and to drive the closure plate to reset after the mounting rod is raised.

[0015] In one embodiment, the enabling component includes: The second wedge block is disposed at the end of the closed plate, and the mounting rod can abut against the inclined surface of the second wedge block when it descends; A first baffle is disposed on the enclosed plate; and The second baffle is disposed inside the outer frame, and a second elastic element is disposed between the baffle and the first baffle.

[0016] Compared with the prior art, the present invention has at least the following advantages: The outer and inner frames of this moisture chamber glasses, combined with a sealing gasket, create a sealed space around the patient's eyes when worn, reducing airflow around the eyes and tear evaporation. When the lenses fog up, defogging is achieved by turning a knob. The knob, driven by a unit, converts a single rotation into a reciprocating motion of the defogging swab descending and rising. Operation is simple; a single action completes a full defogging cycle without continuous operation. A drainage mechanism at the bottom of the cavity automatically opens when the defogging swab descends to absorb water, promptly draining the collected moisture and preventing secondary fogging due to evaporation. The drainage mechanism automatically closes after the defogging swab rises, restoring the sealed, moisturized environment. The entire system requires no heating elements or circuit control, featuring a simple, reliable, and inexpensive structure. Defogging is completed with a simple knob turn, providing rapid response without waiting, allowing users to quickly regain clear vision while maintaining the moisture-protecting function of the glasses. This balances comfort and practicality, ensuring lens clarity even during extended wear. Attached Figure Description

[0020] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] Please see Figures 1 to 4 The present invention provides a wet room mirror that prevents lens fogging, including an outer frame 1, two sets of lenses 2 and two sets of inner frames 10 are provided on the outer frame 1, a sealing gasket 32 ​​is provided on one side of the inner frame 10, and a mounting shell 12 is provided at the end of the inner frame 10. The mounting shell 12 communicates with the cavity formed between the outer frame 1 and the inner frame 10, and a temple 31 is hinged to one end of the mounting shell 12.

[0024] The wet chamber glasses are worn through the temples 31, and the arrangement of the sealing gaskets 32 makes the outer frame 1, inner frame 10 and mounting shell 12 form a sealed cavity, thereby reducing the evaporation of moisture and the flow of gas in the eyes, so as to keep the eyes moist.

[0025] Please see Figures 5 to 7 In this embodiment, a defogging cotton strip 18 is provided in the cavity and can be raised and lowered. The defogging cotton strip 18 abuts against the lens 2. A rotatable knob 26 is provided on one side of the mounting shell 12. The knob 26 is connected to the defogging cotton strip 18 through a drive unit so that the single rotation of the knob 26 is converted into driving the defogging cotton strip 18 to descend and then driving the defogging cotton strip 18 to rise after it descends to the lowest point. The drive unit includes a mounting rod 14 that can be raised and lowered and is provided in the cavity formed between the outer frame 1 and the inner frame 10. The defogging cotton strip 18 is located on one side of the mounting rod 14. By controlling the mounting rod 14 to rise and fall in the cavity formed between the outer frame 1 and the inner frame 10, the defogging cotton strip 18 can be driven to rise and fall, thereby wiping the lens 2 and quickly defogging the lens 2.

[0026] Please see Figure 4 , 5 In this embodiment, the driving unit further includes a driving rod 20. One end of the driving rod 20 is hinged to the mounting rod 14, and both sides of the other end are provided with limiting posts 21. A sliding groove 13 is provided inside the mounting housing 12. One set of limiting posts 21 is slidably and rotatably engaged in the sliding groove 13. The limiting posts 21 can be controlled to slide within the sliding groove 13, causing the driving rod 20 to deflect, thereby pushing the mounting rod 14 downward to perform a wiping action. The resetting of the limiting posts 21 can control the mounting rod 14 to reset, ready for the next wiping operation.

[0027] Please see Figure 4 , 5 8. In this embodiment, the driving unit also includes a linkage mechanism disposed on the knob 26 and connected to another set of limiting posts 21. The linkage mechanism converts the single rotation of the knob 26 into driving the limiting posts 21 to perform a single reciprocating slide. The linkage mechanism includes a drive disk 23 rotatably disposed within the mounting housing 12. A first control component is provided on the knob 26, which can be intermittently connected to the drive disk 23. The rotation of the knob 26 is converted into the rotation of the drive disk 23 by the first control component. The first control component includes a first gear 27 disposed on the knob 26, with a notch 28. A second gear 33 is disposed on one side of the drive disk 23, which can mesh with the first gear 27. A ratchet 29 is fixedly disposed on the first gear 27. A pawl 30 is also provided on the mounting housing 12, which is hinged by a torsion spring. The pawl 30 is engaged with the ratchet 29. One end of the constant force spring 25 is connected to the axis of the second gear 33, and the other end is connected to the mounting housing 12. The number of teeth of the first gear 27 is half the number of teeth of the second gear 33.

[0028] The linkage mechanism also includes a second control component mounted on the drive disc 23 and connected to the limiting post 21. The second control component converts the rotation of the drive disc 23 into the sliding of the limiting post 21. The second control component includes a drive frame 22 that is slidably engaged in the mounting housing 12 along the extension direction of the slide groove 13. The limiting post 21 is rotatably mounted at the end of the drive frame 22. A drive post 24 is eccentrically mounted on one side of the drive disc 23 and is slidably engaged in the drive frame 22.

[0029] The first gear 27 can be rotated by turning the knob 26. When the first gear 27 meshes with the second gear 33, the first gear 27 can drive the second gear 33 to rotate during the rotation, thereby controlling the rotation of the drive disk 23. During the rotation of the drive disk 23, the drive frame 22 can be controlled to slide laterally. When the drive frame 22 slides, it can push one of the limit posts 21, so that the mounting rod 14 moves down and the defogging cotton strip 18 on one side wipes the lens 2. When the knob 26 rotates one revolution, the arrangement of the notch 28 causes the first gear 27 to disengage from the second gear 33. Under the action of the constant force spring 25, the drive disc 23 can be reset, thereby controlling the defogger stencil 18 to reset for the next use. Furthermore, the arrangement of the ratchet 29 and the pawl 30 can provide one-way self-locking for the rotation of the knob 26, preventing the knob 26 from reversing. This makes driving the defogger stencil 18 easier and ensures that the defogger stencil 18 can be reset to the highest point, avoiding obstruction of the user's view.

[0030] Please see Figures 4 to 7 In this embodiment, the mounting rod 14 and the defogging cotton strip 18 are connected by a compression assembly. The compression assembly compresses the defogging cotton strip 18 when the mounting rod 14 descends to its lowest point. The compression assembly includes a receiving rod 15, and a mounting post 16 is provided on one side of the receiving rod 15. The mounting post 16 is slidably inserted on the mounting rod 14 along its axis. The defogging cotton strip 18 is provided on one side of the receiving rod 15. A first elastic element 17 is provided between the receiving rod 15 and the mounting rod 14. An abutment block 11 is provided on one side of the inner frame 10. A first wedge block 19 is provided at the end of the receiving rod 15. After the receiving rod 15 descends, the inclined surface of the first wedge block 19 can abut against the abutment block 11.

[0031] By arranging the first elastic element 17, the contact force between the defogging cotton strip 18 and the lens 2 can be increased, thereby improving the defogging effect. When the defogging cotton strip 18 moves down to the lowest position, the inclined surface of the first wedge block 19 abuts against the abutting block 11, thereby pushing the receiving rod 15 to slide towards the lens 2 to squeeze the defogging cotton strip 18, so that the defogging cotton strip 18 has good water absorption in subsequent use.

[0032] Please see Figure 1 , 24. In this embodiment, a drainage mechanism is provided at the bottom of the cavity formed between the outer frame 1 and the inner frame 10. The drainage mechanism opens after the defogging cotton strip 18 descends and closes after the defogging cotton strip 18 rises. The drainage mechanism includes a mounting frame 4 disposed inside the outer frame 1, which communicates with the outside. An absorbent cotton block 5 is disposed inside the mounting frame 4. A sealing plate 6 is slidably disposed on the outer frame 1, which covers the top opening of the mounting frame 4. An opening component connected to the mounting rod 14 is provided on the sealing plate 6. The opening component drives the sealing plate 6 to slide open after the mounting rod 14 descends and drives the sealing plate 6 to reset after the mounting rod 14 rises. The opening component includes a second wedge block 8 disposed at the end of the sealing plate 6, which abuts against the inclined surface of the second wedge block 8 when the mounting rod 14 descends. A first baffle 7 is disposed on the sealing plate 6, and a second baffle 3 is disposed inside the outer frame 1. A second elastic member 9 is disposed between the second baffle 3 and the first baffle 7.

[0033] The mounting rod 14 moves downward and, while pressing the defogging cotton strip 18 through the receiving rod 15, abuts against the inclined surface of the second wedge block 8, thereby controlling the sliding opening of the sealing plate 6. The second elastic element 9 is compressed by the first baffle 7. When the defogging cotton strip 18 is pressed, it comes into contact with the water-absorbing cotton block 5, and the water produced is absorbed by the water-absorbing cotton block 5. After the mounting rod 14 is reset, the sealing plate 6 is reset under the action of the second elastic element 9, so that the eye space remains sealed. The water absorbed by the water-absorbing cotton block 5 can be released into the outside space, thereby draining water while ensuring the eye space is sealed, thus improving the subsequent defogging effect.

[0034] Specific usage and beneficial effects of the present invention: The outer frame 1 and inner frame 10 of this moisture chamber glasses, together with the sealing gasket 32, create a sealed space around the patient's eyes when worn, reducing airflow around the eyes and tear evaporation. When the lens 2 fogs up, it can be defogging by turning the knob 26. The knob 26, through a drive unit, converts a single rotation into a reciprocating motion of the defogging cotton strip 18 descending and rising once. Operation is simple; a single action completes a full defogging cycle without continuous operation. A drainage mechanism is located at the bottom of the cavity, automatically opening when the defogging cotton strip 18 descends to absorb water, promptly draining the collected moisture and preventing it from evaporating again and causing secondary fogging. The drainage mechanism automatically closes after the defogging cotton strip 18 rises, restoring the internal sealed and moisturized environment. The entire system requires no heating elements or circuit control, featuring a simple, reliable, and inexpensive structure. The defogging process is completed simply by turning the knob 26, with a rapid response and no waiting time, allowing the user to quickly regain clear vision while maintaining the moisture-protecting function of the moisture chamber glasses. It balances comfort and practicality, and the lens 2 remains clear even after prolonged wear.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
