Description

Technical Field

[0001] The invention relates to the technical field of ski goggles, in particular to goggles for skiing. Background Art

[0002] Ski goggles, also known as ski goggles, are glasses used to protect the eyes when skiing. Because the sunlight reflects strongly on the snow, and the cold wind during skiing is very irritating to the eyes, ski goggles are needed to protect the skier's eyes.

[0003] In the prior art, the ventilation of ski goggles is simply used to keep the temperature difference between the inside and outside of the ski goggles small, prevent the lenses from fogging up and affecting vision, and remove water vapor to prevent the lenses from fogging up. However, in this principle of simply using ventilation, when skiing at a too fast speed, the air intake speed in the ski goggles will also increase, especially when skiing outdoors in winter, and a large amount of cold wind will enter the ski goggles, which will also seriously affect vision. When skiing at a slow speed, the air intake speed will also be affected, and the small air volume will slow down the water vapor discharge speed in the ski goggles, which will cause fogging on the inside of the ski goggles and affect vision.

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1-7 , a pair of ski goggles, comprising a frame 1 and a lens 2, which is a conventional structure of ski goggles currently circulated in the market, wherein the frame 1 is used to support the lens 2, and the lens 2 is used to filter sunlight and protect the eyes, and the frame 1 is worn on the head through a fixing belt, and the lower end face of the frame 1 has a concave surface adapted to the shape of the nose bridge, specifically, to make the protruding nose extend out to play a role of avoidance, but due to the thickness of the goggles, a plane with thickness is formed, and an air inlet 3 is provided on the upper end face of the frame 1, and an air outlet 4 is provided on the lower end face of the frame 1. During use, when the wind is coming towards you while skiing, the wind enters the inside of the goggles from the air inlet 3 and is discharged from the air outlet 4 below. In this process, cold air is allowed to enter to control the temperature difference between the inside and outside of the goggles to prevent the lens 2 from fogging, and at the same time, the wind flowing inside the goggles will take away water vapor, and prevent the water vapor from fogging inside the lens 2 and affecting the vision;

[0037] An air inlet volume control mechanism is provided at the air inlet 3 to control the air inlet volume at the air inlet 3. The air inlet volume control mechanism controls the air inlet volume at the air inlet 3 according to the amount of wind it receives when facing the wind. When the wind volume increases, that is, the wind volume increases as the skiing speed increases, the wind pressure received by the air inlet volume control mechanism increases. At this time, the air inlet volume control mechanism controls the air inlet diameter to decrease through the increased wind pressure, and the reduced air inlet diameter achieves the effect of stabilizing the air inlet volume of the goggles. On the contrary, there are two situations. When the skiing speed slows down and the wind volume received increases, the air inlet diameter decreases. When the air volume decreases, the wind pressure on the air volume control mechanism decreases. Then the air volume control mechanism controls the air inlet diameter from small to large through the wind pressure to ensure that the air volume is sufficient until the air volume control mechanism reaches the air inlet diameter in the natural state. In the other case, when the air volume is always small, the wind pressure on the air volume control mechanism is not enough to change the air inlet diameter. At this time, the air volume of the air volume control mechanism in the natural state, that is, the conventional air inlet diameter without force, can meet the needs of ventilation and exhaust and avoid the generation of water mist.

[0038] A wind guide structure is provided at the air outlet 4 to guide the wind at the air outlet 4 to the bottom of the air outlet 4. The wind guide structure can guide the oncoming wind to flow below the air outlet 4. The wind flowing below the air outlet 4 forms an airflow that accelerates the discharge of air inside the goggles, so as to better ensure the ventilation and exhaust effects, and will not allow the oncoming wind to flow into the goggles through the air outlet 4.

[0039] Furthermore, a foam sponge 5 is provided on the side of the frame 1 opposite to the lens 2. The foam sponge 5 is made of a soft material and is light in texture. It is very comfortable to wear and can effectively prevent the lens of the glasses from being damaged due to collision or friction, thereby extending the service life of the glasses.

[0040] Furthermore, the air intake control mechanism includes an air intake cover 6 disposed on the upper end surface of the frame 1, the air intake cover 6 is connected to the air inlet 3, and has an opening 7 for air intake. The air intake cover 6 protrudes from the upper end surface of the frame 1 and allows air to enter more easily from the opening 7 and enter the air inlet 3;

[0041] It also includes a first windshield 8 and a second windshield 9, one end of the first windshield 8 is connected to a surface of a side of the inner side of the air inlet 3 close to the lens 2, the other end of the first windshield 8 extends upward into the air inlet cover 6, and an air inlet channel is left between the inner wall of the air inlet cover 6, one end of the second windshield 9 is connected to the inner upper wall of the air inlet cover 6, the other end of the second windshield 9 extends downward to the upper end surface of the frame 1 and is located above the air inlet 3, and an air inlet channel is left between the second windshield 9 and the upper end surface of the frame 1;

[0042] The first wind shield 8 is a rigid non-deformable shield, and the second wind shield 9 is an elastically bendable and deformable shield, and can be made of a material such as rubber that can be elastically deformed and recoverable.

[0043] Specifically, the wind entering the air inlet 3 is first blocked by the second wind shield 9. If the wind force is strong, the second wind shield 9 will be elastically deformed and bent, and its bending direction is toward the first wind shield 8. At this time, the distance between the first wind shield 8 and the second wind shield 9 is reduced, which is equivalent to reducing the diameter of the air inlet. However, because the wind velocity is fast, the air inlet diameter is reduced to balance it, so that the air volume inside the goggles is controlled at an appropriate amount to ensure its anti-fogging effect. That is, the wind entering the air inlet cover 6 enters the air inlet 3 through the gap between the first wind shield 8 and the second wind shield 9, then enters the inside of the goggles from the air inlet 3, and then is discharged from the air outlet 4, completing ventilation and exhaust to avoid fogging.

[0044] Furthermore, a ventilated and breathable first foam layer 10 is connected between the side surface of the first windshield 8 opposite to the lens 2 and the inner surface of the air inlet 3. The first foam layer 10 is a polyurethane foam with open holes. The first foam layer 10 has a ventilation effect while preventing the incoming wind from rapidly pouring into the inside of the goggles and affecting the field of vision. The foam material of the first foam layer 10 is also hygroscopic, which helps prevent the goggles from fogging.

[0045] Furthermore, a second foam layer 11 for ventilation and air permeability is provided on the side of the upper end of the first windshield 8 facing the second windshield 9. The second foam layer 11 prevents the second windshield 9 from being attached to the first windshield 8. The second foam layer 11 is a polyurethane foam with open pores. The second foam layer 11 has a ventilation effect and is also located between the first windshield 8 and the second windshield 9, so that the second windshield 9 cannot be attached to the first windshield 8, so as to ensure that when the second windshield 9 is bent to the closest distance between the second windshield 9 and the first windshield 8, wind can also enter the inside of the goggles.

[0046] Furthermore, the lower end of the second wind shield 9 is connected to a retaining plate 12 extending toward the side where the first wind shield 8 is located. The retaining plate 12 is designed to be retained on the second foam layer 11 when the second wind shield 9 is bent to the maximum, that is, when it is attached to the second foam layer 11, so as to prevent the second wind shield 9 from being blown by the wind to the top of the first wind shield 8 and being unable to rebound.

[0047] Furthermore, the wind guide structure includes a third wind shield 13, one end of the third wind shield 13 is connected to the lower end surface of the frame 1 and is located on the side of the air outlet 4 close to the lens 2, and the other end is extended downward, and the end of the third wind shield 13 extending downward is curved in an arc shape in the direction opposite to the lens 2 and extends to the bottom of the air outlet 4;

[0048] A third foam layer 14 is disposed inside the air outlet 4 , and the third foam layer 14 is polyurethane foam with open pores.

[0049] Specifically, the arc-shaped structure of the third windshield 13 and its extension direction can guide the oncoming wind to flow below the air outlet 4, and the wind flowing below the air outlet 4 forms an airflow that accelerates the discharge of air inside the goggles, so as to better ensure the ventilation and exhaust effects, and prevent the oncoming wind from flowing into the goggles through the air outlet 4. The foam material of the third foam layer 14 is also hygroscopic, which helps prevent the goggles from fogging.

[0050] Furthermore, a windproof mask is detachably provided on the lower end surface of the frame 1, and the windproof mask includes a mask body 15 covering the mouth and nose, and a ventilation structure is provided on the upper end of the mask body 15 for detachably connecting and ventilating with the concave surface on the frame 1 that matches the shape of the bridge of the nose, and a one-way air intake structure connected to the ventilation structure is provided in the middle part of both sides of the mask body 15, so as to introduce the air inside the frame 1 and the lens 2 into the mask body 15 through the ventilation structure when inhaling, and an exhaust structure is provided at the lower end of the mask body 15 for exhausting air; when in use, the ventilation structure at the upper end of the mask body 15 is installed on the frame 1 The mask 15 is covered at the mouth and nose position, and an elastic band can be set on the mask body 15 so that it can be put on the head to stably fix the mask body 15. At this time, the mask body 15 is connected to the air inside the frame 1. During the user's breathing process, when inhaling, part of the air enters from the exhaust structure, and the other part is introduced into the mask body 15 through the ventilation structure through the one-way air intake structure, and the air intake amount of the one-way air intake structure and the exhaust structure is balanced, ensuring that under normal breathing conditions, the one-way air intake structure can also introduce the air inside the frame 1 and the lens 2 into the mask body 15. When exhaling, the one-way air intake structure is closed to prevent the exhaled gas from entering the space inside the frame 1 and the lens 2, and to avoid fogging. At this time, all the exhaled gas is discharged from the exhaust structure. The windproof mask is suitable for outdoor harsh environments. While ensuring that breathing is not affected by cold air and strong winds, it can also increase the discharge effect of moisture in the space inside the frame 1 and the lens 2.

[0051] The ventilation structure includes an air inlet cavity 16 fixedly connected to the top of the outer side of the cover body 15, and an air inlet tube 17 connected thereto is arranged on the top of the air inlet cavity 16. The concave surface on the frame 1 has a socket 18 for inserting the air inlet tube 17. An interference fit is adopted between the socket 18 and the air inlet tube 17 so that the air inlet tube 17 can be stably inserted into the socket 18 and is not easy to fall off. A third foam layer 14 covering the bottom of the air inlet tube 17 is arranged on the top surface of the inner side of the air inlet cavity 16. The third foam layer 14 is a polyurethane foam with open pores, which has a hygroscopic effect and also prevents moisture from entering the inner space of the frame 1 and the lens 2 and fogging. When inhaling, a negative pressure is formed in the air inlet cavity 16, and the air in the inner space of the frame 1 and the lens 2 is introduced into the air inlet cavity 16 for use through the air inlet tube 17 inserted into the socket 18. The main function of the jack 18 is to install the air intake cannula 17. When the windproof mask is not needed, the jack 18 is exposed. At this time, a plug with the same structure as the air intake cannula 17 can be inserted into the jack 18 to block the hole. This conventional method will not be repeated here.

[0052] Furthermore, the one-way air intake structure includes an inner groove body 19 arranged in the middle part of the side surface of the cover body 15, the inner groove body 19 is connected to the air intake cavity 16 by setting an air pipe 20, and an elastic baffle 21 is connected to the upper end of the inner side of the inner groove body 19, and the elastic baffle 21 extends downward to cover the inner groove body 19.

[0053] Specifically, by utilizing the elastic deformation of the elastic baffle 21, when inhaling, under the influence of negative pressure, the air in the air inlet cavity 16 passes through the trachea 20 to the inner groove body 19, at which time the elastic baffle 21 opens, allowing air to enter the mask body 15 for breathing. When exhaling, the air pressure in the mask body 15 rises instantly, and the elastic baffle 21 is affected by the air pressure and instantly covers the inner groove body 19 and blocks the trachea 20 inside the inner groove body 19, preventing the exhaled gas from entering the air inlet cavity 16 and then entering the inside of the goggles. Among them, the trachea 20 part inside the inner groove body 19 can be designed as an inclined surface so that the elastic baffle 21 can be more easily attached to the inner side of the inner groove body 19 to block the trachea 20 faster.

[0054] Furthermore, the exhaust structure includes an exhaust port 22 arranged on the lower end surface of the cover body 15, a protective net 23 is arranged in the exhaust port 22, and a fourth foam layer 24 covering the protective net 23 is arranged on the inner lower end surface of the cover body 15, and the fourth foam layer 24 is a polyurethane foam with open holes. Among them, the protective net 23 plays a protective effect and is breathable, and through the fourth foam layer 24 which also has a breathable effect, it plays an auxiliary moisture absorption role to prevent the generation of water vapor in the cover body 15 from affecting breathing. In addition, in order to prevent the exhaust from being affected by the freezing of water vapor on the protective net 23, it can also be designed that the protective net 23 and the fourth foam layer 24 can be disassembled, replaced, and cleaned, so that the fourth foam layer 24 is with the protective net 23, and the protective net 23 is detachably connected to the inner side of the exhaust port 22 for easy disassembly, replacement, and cleaning, and the clamping structure is a conventional method and will not be repeated.

[0055] To sum up, the goggles are provided with an air inlet and an air outlet on the frame, and an air inlet control mechanism and a wind guide structure are respectively provided at the air inlet and the air outlet. The air inlet control mechanism can adjust and control the air inlet according to the amount of wind received, and the wind guide structure ensures the air outlet and avoids a large amount of wind pouring in, so as to balance the air inlet and outlet, and generally ensure that a relatively stable air volume circulates inside the goggles to ensure the temperature difference between the inside and outside and the water vapor discharge, so as to more stably avoid the fogging of the inside of the goggles for skiing that affects the vision, thereby improving the user experience of the goggles.

[0056] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
