Description

Technical Field

[0001] The invention relates to the technical field of goggles, in particular to an anti-fog goggles with a hydrophobic drainage structure. Background Art

[0002] Goggles are glasses worn during sports or work, mainly used to protect the eyes from damage caused by splashing objects, chemicals, infectious body fluids (such as droplets, blood, etc.) and strong light, especially in the self-protection of medical staff, goggles are currently the main tool used for eye and face protection. However, in actual use, when the temperature and relative humidity of the gas in the space defined between the goggles body and the user's face and eyes reaches the dew point, a condensation similar to "fog" will form on the inner surface of the goggles, causing the goggles to fog and become unclear. This fogging phenomenon will bring many inconveniences and serious consequences to the users. When fogging occurs, the user's field of vision will be greatly reduced and become blurred, making it impossible to continue the current action, or causing serious consequences due to the inability to see the current situation clearly. For example, when medical staff use the goggles, when the goggles fog up, it will seriously block the line of sight, causing great trouble to the clinical work of medical staff or serious medical accidents; or when the user is wearing goggles and moving at a high speed among fixed obstacles, when the goggles fog up, it will cause serious physical injuries to the user.

[0003] In the prior art, the technologies for preventing goggles from fogging mainly include the following methods: spraying an anti-fog spray or applying an anti-fog layer on the lenses of the goggles, adding an automatic defogger to the goggles, and opening ventilation holes on the goggles. For example, Chinese patent CN201642545U discloses a breathable anti-fog goggles, on which the lenses of the goggles are sprayed with an anti-fog agent to prevent the generation of fog. However, this method has a general anti-fog effect and is not long-lasting. Chinese patent CN108983440A discloses an anti-fog goggles that are easy to replace lenses, and CN203385955U discloses an automatic defog sports glasses. Both of these technologies are to set a heating element on the lens body, and the heat generated when the heating element is energized can make the temperature of the lens The temperature rises, and the water vapor in contact with the lens is heated and evaporated, thereby achieving the effect of automatically removing the water mist on the lens and playing an anti-fog role. However, such devices all require electronic components, which have a complex structure, and moisture will enter the electronic components to cause a short circuit, thereby making the device unable to be used normally; in addition, Chinese patent CN203417287U discloses an anti-fog goggles for biological products, which are provided with air holes, and the air holes are provided with hole covers. When necessary, the hole covers can be opened to connect the inner cavity with the outside, thereby achieving the effect of eliminating fog. However, the anti-fog effect of this method is general, the generated condensed water cannot be effectively discharged, and manual operation is required to defog at intervals, which affects the convenience of use.

[0023] Example 1

[0024] like Figure 1-3 As shown, the anti-fog goggles of this embodiment include a frame 1, a lens 2 and a fixing structure 7, wherein the fixing structure 7 is an elastic elastic band, and its two ends are connected to the frame 1 through fixing buckles 9, a lens slot is provided on the front side of the frame 1, and the lens 2 is embedded in the lens slot, and a drainage structure is provided on the frame 1, and the drainage structure includes two water-absorbing sponge slots 6, two water guide grooves 10 and two drainage holes 4.

[0025] The two water-absorbing sponge slots 6 are respectively located at the two ends of the lower edge of the frame on the outer side of the lens, and are integrally formed with the frame 1, and are in the shape of a strip-shaped open structure with a baffle in the front, where the front here refers to the side away from the lens; the two water guide grooves 10 are respectively located at the two ends of the lower edge of the frame on the inner side of the lens, and are in the shape of a strip-shaped open structure, which is opened along the inner side of the lower edge of the frame and is adjacent to the lens slot; a drainage hole 4 is provided between the water guide groove 10 and the water-absorbing sponge slot 6, and the drainage hole 4 is in the shape of a rectangular through hole and is located at the lowest point of the water guide groove 10; the lowest ends of the two water-absorbing sponge slots 6 are located on the lower side of the two drainage holes 4.

[0026] It should be noted that the inner side of the lens refers to the side closer to the human face when the user wears the goggles, and the outer side of the lens refers to the side away from the human face when the user wears the goggles.

[0027] The surface of the lens 2 has a TiO2 hydrophobic coating, which can quickly condense fog into water droplets to prevent the lens from fogging. In addition, it also has the effect of cleaning the lens.

[0028] The lower edge of the rear side of the frame 1 is also provided with a decompression sealing strip 8. When the user wears the goggles, on the one hand, the decompression sealing strip can relieve the pressure of the goggles on the nose and cheeks of the human body. On the other hand, if the goggles are used in combination with a mask, the decompression sealing strip can make the lower edge of the goggles and the upper edge of the mask closely contact the skin to prevent the exhaled gas in the mask from overflowing into the goggles. In addition, the decompression sealing strip 8 also has the effect of preventing the lens from fogging.

[0029] It should be noted that the back side of the frame refers to the side closer to the human nose bridge and face, and the front side of the frame refers to the side away from the human nose bridge and face.

[0030] When the anti-fog goggles of the present invention are in use, the water-absorbing sponges 5 are respectively placed in the two water-absorbing sponge slots 6. When the water droplets condensed on the inner side of the lens 2 flow into the water guide groove 10, they will gather near the drainage hole 4, and then flow into the water-absorbing sponge slots 6 through the drainage hole 4, thereby being absorbed by the water-absorbing sponges 5. When the water-absorbing sponges 5 are saturated with water, they can be replaced from the outside of the goggles without contaminating the inner side of the lens 2.
