Description

Technical Field

[0001] The present invention relates to the technical field of glasses, in particular to a pair of glasses with defogging and cleaning functions. Background Art

[0002] During cycling, when the user sweats, the inner wall of the lens of sports glasses will often fog up, affecting the user's vision. In order to prevent the lens from fogging, many sports glasses are coated with chemical defoggers on the inner wall of the lens. However, the effective time of chemical defoggers is short, and frequent application is required to achieve the anti-fog effect. Frequent application will cause wear on the lens surface, affecting the transmittance and clarity. Referring to the patent with authorization announcement number CN219423128U, it can be seen that the patent discloses an anti-fog comprehensive medical goggles, which are provided with an extended hollow lens frame; an increased distance from the lens to the eye; a double-layer lens, respectively mounted on the inner and outer sides of the extended hollow lens frame; a surfactant layer, coated on the surface of the inner lens; the extended hollow lens frame includes a temperature-sensing heating circuit placed inside the extended hollow lens frame, a heat-insulating material layer wrapped around the outside of the extended hollow lens frame, a flexible gasket on the edge of the extended hollow lens frame, and a sealing ring at the bottom of the frame.

[0003] The lenses of some sports glasses are equipped with a nano anti-fog coating. The nano anti-fog coating on the lenses has poor scratch resistance. Daily wiping can easily cause the anti-fog function to deteriorate, and it needs to be used with specific cleaning agents. Summary of the Invention

[0004] The purpose of the present invention is to provide glasses and an air guide structure with defogging and cleaning functions to solve the problems in the prior art of cumbersome use of chemical defogging agents and easy loss of nano anti-fog coatings, and to prevent airflow from directly eroding the eyes and causing discomfort.

[0005] The object of the present invention is achieved by: a pair of glasses with a defogging and cleaning function, comprising a frame, lenses, and a pair of temples, including a strip-shaped member, the strip-shaped member extending along the length of the upper edge of the frame, the strip-shaped member being fixedly connected to the inner side of the upper edge of the frame, the rear side of the strip-shaped member being in contact with the forehead to prevent sweat from flowing;

[0006] A gap is left between the strip-shaped component and the upper edge of the frame, and the gap forms a guide channel for guiding the oncoming airflow to blow toward the inner wall of the lens.

[0007] Furthermore, a side of the strip-shaped component facing the upper edge of the frame is provided with a guide concave surface extending along its side length, so that the oncoming airflow changes its direction to blow towards the inner wall of the lens after passing through the guide concave surface.

[0008] Furthermore, when observed from a cross-sectional perspective, the rear edge of the upper edge of the frame is a curved surface that arches backward, and the rear edge of the upper edge of the frame and the guide concave surface constitute the guide channel.

[0009] Furthermore, a plurality of position-limiting connectors are fixed to the front side of the strip-shaped component, and the position-limiting connectors are detachably fitted with the rear edge of the upper edge of the frame.

[0010] Furthermore, the middle of the strip-shaped component extends upward beyond the upper side of the upper edge of the frame, and a pair of limiting connectors are fixed to the front side of the strip-shaped component. The two limiting connectors are distributed on the left and right based on the position of the nose pad, so that the oncoming airflow is guided by the guide channel to flush the visual area of the inner wall of the lens.

[0011] Furthermore, at least one locking protrusion is fixed to the front side of the strip-shaped component, and the locking protrusion is detachably connected to the upper edge of the frame.

[0012] As another aspect of the present invention, a wind guide structure is proposed based on the above-mentioned glasses, which includes two wind guide plates respectively connected to the two temples, and the wind guide plates are provided with wind guide ports connected to their outer surfaces and inner surfaces. The wind guide ports face rearward, and the airflow flowing through the guide channel and blowing toward the inner wall of the lens is discharged backward along the inner wall of the wind guide plate through the air guide ports.

[0013] The front side and the upper side of the wind deflector are respectively fitted with the frame and the temples.

[0014] The air guide plate is divided into a front guide plate portion and a rear guide plate portion that are connected as one piece. The air guide port is located at the connection between the front guide plate portion and the rear guide plate portion. The connection between the front guide plate portion and the rear guide plate portion is configured as a breakable portion that breaks quickly in an impact state.

[0015] The tail of the rear guide plate portion is warped outward, and in the impact state, the inner side of the tail of the rear guide plate portion is in smooth contact with the outside of the user's ear; the inner wall of the front guide plate portion is set as an inner guide surface for guiding the airflow to the air guide port, and the outer wall of the rear guide plate portion is provided with an outer guide surface, and the inner guide surface, the air guide port, and the outer guide surface are connected in sequence.

[0016] The beneficial effects of the present invention are:

[0017] 1. The space between the strip-shaped member and the upper edge of the frame forms a guide channel for directing the oncoming airflow to the inner wall of the lens, guiding the oncoming airflow to flush the inner wall of the lens so that the oncoming airflow does not impact the eyes, thereby providing good protection for the user and preventing the airflow from directly flushing the eyes and causing discomfort. It can also alleviate the accumulation of dust on the lens to a certain extent and prevent the formation of fog inside the lens through air flow;

[0018] 2. Excellent anti-fog effect. The specially designed diversion channel guides the air flow to flush the inner wall of the lens for rapid defogging, and also prevents contamination caused by anti-fog liquid coating on the lens surface;

[0019] 3. The strip-shaped component has a sweat-blocking effect to prevent sweat from flowing down to the eyes, so as to prevent sweat from interfering with the user's vision;

[0020] 4. An air deflector is set on the temple to guide the airflow that washes the lens to be discharged backward and outward;

[0021] 5. A breakable point is set on the wind deflector. When the glasses are hit, the breakable part of the wind deflector can be broken to prevent the wind deflector from directly hitting the ears when it is out of the use position. The wind deflector can smoothly contact the outside of the ear, thereby reducing damage to the human body and the ear. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is a combination of the embodiments of the present invention Figure 1-8 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] like Figure 1-5As shown, a pair of sports glasses with a defogging and cleaning function is provided, comprising a frame 1, lenses 2, and a pair of temples 3. The strip-shaped member 4 (which may be made of plastic or other materials, without limitation) extends along the length of the upper edge 1a of the frame 1 and is fixedly connected to the inner side of the upper edge 1a of the frame 1. The rear side of the strip-shaped member 4 abuts against the forehead to prevent sweat from flowing downward to the eyes. From a bird's-eye view, the frame 1 and the strip-shaped member 4 are curved forward as a whole, and the rear side of the strip-shaped member 4 matches the curve of the forehead.

[0032] like Figure 2 、 3 As shown, a gap is left between the above-mentioned strip-shaped component 4 and the upper edge 1a of the frame 1, and the gap is formed into a guide channel 5 for guiding the oncoming airflow to blow toward the inner wall of the lens 2. During riding, the user's head leans forward, and the guide channel 5 tilts forward to guide the oncoming airflow to blow toward the inner wall of the lens 2, flushing the inner wall of the lens 2, so that the oncoming airflow will not impact the eyes, thereby forming a good protection for the user and preventing the airflow from directly flushing the eyes and causing discomfort.

[0033] like Figure 3 As shown, the strip-shaped member 4 is provided with a guide concave surface 4a extending along the side length thereof on one side facing the upper edge portion 1a of the frame 1. When viewed from a cross-sectional perspective, the guide concave surface 4a may be C-shaped or V-shaped, with the opening facing forward, facing the rear side of the upper edge portion 1a of the frame 1, so that the oncoming airflow changes direction after passing through the guide concave surface 4a to blow toward the inner wall of the lens 2.

[0034] Observed from a cross-sectional perspective, the rear edge of the upper edge 1a of the frame 1 is a curved surface that arches backward. The rear edge of the upper edge 1a of the frame 1 and the guide concave surface 4a form a guide channel 5. The formed guide channel 5 is equivalent to a C-shape or a V-shape. After entering the guide channel 5, the oncoming airflow changes its direction, causing the airflow to flush the inner wall of the lens 2.

[0035] like Figure 2 、 6 As shown, the middle of the above-mentioned strip member 4 extends upward beyond the upper side of the upper edge 1a of the frame 1, and a pair of limiting connectors 4c are fixed to the front side of the strip member 4. The limiting connector 4c is set as a plate structure (or other structure) and is set as a streamlined structure. The two limiting connectors 4c are distributed left and right based on the position of the nose pad, so that the oncoming airflow is guided by the guide channel 5 to flush the visual area of the inner wall of the lens 2, and the limiting connector 4c is detachably matched with the rear side of the upper edge 1a of the frame 1.

[0036] The limiting connector 4c plays the following roles:

[0037] 1. Fix and connect the strip-shaped member 4 to enhance the connection strength between the strip-shaped member 4 and the frame 1;

[0038] 2. Play a guiding role and guide the airflow to flush the visual area of the inner wall of the lens 2;

[0039] 3. Streamlined structure to reduce wind resistance.

[0040] A locking protrusion 4b is integrally formed in the center of the front side of the strip-shaped member 4. The locking protrusion 4b is detachably connected to the upper edge 1a of the frame 1. The number and specific location of the locking protrusions 4b are not limited herein, and the method of connecting the locking protrusion 4b to the upper edge 1a of the frame 1 can also be specially configured according to the circumstances and is not limited herein.

[0041] The sports glasses are also provided with an air guide structure, which includes two air guide plates 6 respectively connected to the two temples 3. The air guide plates 6 are provided with air guide ports 603 connected to their outer and inner surfaces. The air guide ports 603 face backwards, and the air flow flowing through the guide channel 5 and blowing toward the inner wall of the lens 2 is discharged backwards along the inner wall of the air guide plate 6 through the air guide port 603. The air guide plate 6 can guide the air flow to be discharged backwards and outwards.

[0042] like Figure 1 、 7 As shown, the front and upper sides of the wind deflector 6 are respectively attached to the frame 1 and the temple 3. The wind deflector 6 is integrally connected to two upper connecting members 7. The inner side of the temple 3 is provided with an upper connecting groove 3a extending along the length thereof. The two upper connecting members 7 of the wind deflector 6 are adjustable and inserted into the upper connecting groove 3a, thereby adjusting the position of the wind deflector 6 on the temple 3. The upper connecting member 7 can be a hook-shaped structure or a structure of other structural forms, which is not limited here.

[0043] like Figure 8 As shown, the air guide plate 6 is divided into an integrally connected front guide plate portion 601 and a rear guide plate portion 604. The air guide port 603 is located at the junction of the front and rear guide plates 601 and 604. The junction is provided with a breakable portion 602 that quickly breaks in the event of an impact. The front guide plate 601 is generally outwardly convex, while the rear end of the rear guide plate 604 is warped outward, allowing airflow from the air guide port 603 to flow backward and outward along the rear guide plate 604. The rear end of the rear guide plate 604 is warped outward, so that in the event of a collision, the inner side of the rear end of the rear guide plate 604 comes into smooth contact with the outside of the user's ear.

[0044] In this solution, a breakable point is provided on the wind deflector 6, and its technical function is as follows: when a user falls during riding and his face hits the ground, the glasses are impacted, causing the breakable portion 602 of the wind deflector 6 to break, thereby preventing the wind deflector 6 from directly hitting the ears when it is out of the use position, and the tail of the rear guide portion 604 is warped outward, so that the wind deflector 6 can smoothly contact the outside of the ear, preventing the wind deflector 6 from directly "cutting the ear", thereby reducing damage to the human body and the ear.

[0045] like Figure 7 、 8 As shown, the air guide plate 6 is a streamlined structure as a whole. The inner wall of the front guide plate portion 601 is provided with an inner guide surface 601a for guiding the airflow to the air guide port 603, and the outer wall of the rear guide plate portion 604 is provided with an outer guide surface 604a. The inner guide surface 601a, the air guide port 603, and the outer guide surface 604a are connected in sequence, and the inner guide surface 601a and the outer guide surface 604a are used to guide the airflow to move smoothly backward and outward.

[0046] like Figure 1 As shown, the outer surface of the front guide plate portion 601 of the wind guide plate 6 is provided with at least one wind-cutting edge 601b. The wind-cutting edge 601b is streamlined as a whole and extends from front to back. The wind-cutting edge 601b produces a wind-cutting effect, which can reduce wind resistance and noise.
