Description

Technical Field

[0001] The present application relates to the field of glasses, and in particular to a pair of glasses legs, a glasses frame and goggles. Background Art

[0002] Goggles are glasses that can fit closely to the human face and are used to isolate the human eye from the outside world. However, due to the close fit between the goggles and the human face skin, fog is easily formed on the side of the lens close to the human eye (inside), thereby affecting the line of sight. Summary of the invention

[0003] In order to improve or even solve the problem of internal fogging and inability to defog during use of the above-mentioned goggles, the present application is specially proposed.

[0004] This application is implemented as follows:

[0005] In a first aspect, examples of the present application provide a temple for glasses.

[0006] The temple of the eyeglasses includes a body and a drainage tube. The body has a first end and a second end. The first end is configured to be connected to the eyeglass frame, and the second end is configured to provide a constraint to be attached to the head of the wearer. The drainage tube is hollow and has a third end and a fourth end. The drainage tube is arranged from the third end to the fourth end along the extension direction from the first end to the second end of the body. The third end of the drainage tube matches the frame of the eyeglass frame;

[0007] The drainage tube is provided with an operating section near the fourth end, two one-way valves are provided in the operating section and a pressure ball formed by the expansion of the tube wall is provided between the two one-way valves. The one-way valve is unidirectionally conductive from the third end to the fourth end, and the pressure ball can be squeezed to be in a contracted state and can recover from the contracted state when the squeezing effect is partially or completely eliminated.

[0008] In the example, a hollow channel is constructed in the temple of the glasses, and the channel can generate negative pressure suction effect by the pressure ball. Therefore, when it is applied to products such as glasses and goggles, the hot air near the glasses can be drawn away through the temple of the glasses to prevent condensation in the area corresponding to the eyes, such as on the lens, thereby preventing fogging. Alternatively, products such as goggles based on the temple of the glasses can also drain the fog at the lens position through the temple of the glasses.

[0009] Optionally, the pressure ball is embedded in the body, and the body is soft; or, the pressure ball protrudes from the body, and the body is hard.

[0010] The body of the drainage tube can be made of hard or soft material, which is beneficial to improving the flexibility of its manufacturing process.

[0011] Optionally, the body is hard, the drainage tube is soft, the body is provided with grooves distributed from the first end to the second end, and the drainage tube is removably embedded in the grooves.

[0012] Since the drainage tube is embedded in the groove and is removable, the drainage tube can be replaced when necessary, thereby extending the service life of the temple of the glasses, avoiding waste and reducing the cost of use.

[0013] Optionally, the cross section of the groove is an arc-shaped structure and the diameter is smaller than the outer diameter of the drainage tube.

[0014] The groove is smaller than the drainage tube, and the drainage tube is soft, so the drainage tube is easier to be stably installed in the body of the glasses leg.

[0015] Optionally, the inner wall of the groove is provided with ribs distributed from the first end to the second end, and the ribs are composed of an extrusion section and a limiting section, wherein the extrusion section is adjacent to the first end, and the protruding height of the extrusion section in the radial direction of the groove is greater than the protruding height of the limiting section in the radial direction of the groove.

[0016] The ribs are arranged in the groove to form obstacles to the drainage tube from being separated from the groove, thereby enhancing the stability of the drainage tube.

[0017] In a second aspect, an embodiment of the present application provides a glasses frame, which includes a frame, a wiper, and temples.

[0018] The frame is composed of an upper frame, a lower frame, a left frame and a right frame, and the lower frame is provided with a flow accumulation groove. The wiper is rotatably mounted on the frame, and the rotating shaft is located on the upper frame. The two glasses legs are respectively fixed to the left frame and the right frame of the frame with the first end of the body, and the third end of the drainage tube is connected to the flow accumulation groove.

[0019] The wiper arranged on the glasses frame can be used to remove the water mist condensed on the lens of the frame, and can be used together with the accumulation groove and the drainage pipe to drain the scraped and accumulated mist water, so that the glasses frame has better anti-fogging and defogging effects.

[0020] Optionally, a drying strip is provided in the accumulation trough.

[0021] The drying strip can absorb fog or water vapor to a certain extent, thereby helping to reduce the occurrence of fogging, and can also guide the water flow to a certain extent.

[0022] In a third aspect, an embodiment of the present application provides a pair of goggles, which includes a spectacle frame and a lens, wherein the lens is fixed by an upper frame, a lower frame, a left frame, and a right frame of the spectacle frame.

[0023] The frame shape fits well with the human face and has good sealing and protection effect.

[0024] Optionally, the flow accumulation groove is strip-shaped and extends throughout the lower frame, the lens is provided with a flow guide channel, the flow guide channel is fluidly connected to the flow accumulation groove, and a cotton strip is placed in the flow guide channel.

[0025] Optionally, the lens has a drain port, and the lens surface has a guide pattern, the guide pattern has a diverging portion and a convergent portion, the diverging portion is adjacent to the upper frame, and the convergent portion is adjacent to the lower frame and converges to the drain port.

[0026] In the above implementation process, the goggles provided in the embodiment of the present application can effectively eliminate the fog on the lenses, and can even prevent the lenses from fogging through proper operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians of the art without making creative work are within the scope of protection of the present application.

[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0039] In the description of this application, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the product of the application is usually placed when in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", "third", "fourth", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0040] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] In this application, all embodiments, implementation methods and features of this application can be combined with each other without contradiction or conflict. In this application, conventional equipment, devices, components, etc. can be purchased commercially or made according to the contents disclosed in this application. In this application, in order to highlight the key points of this application, some conventional operations and equipment, devices, and components are omitted or simply described.

[0042] Goggles are protective equipment widely used in many fields. Generally, goggles are worn in a sealed wrapping style on the face, mainly the eyes. Therefore, goggles (especially lenses) are easily fogged due to skin sweating or nasal breathing. Or, for non-sealed wrapping goggles, fogging occurs due to exhalation or air. Therefore, goggles fogging is a problem that needs to be solved urgently.

[0043] For the above problems, it is hoped that the glasses can prevent fogging. Or, better yet, it is hoped that the glasses can be quickly defogged after fogging. To address these problems, there are already some solutions and products, such as electric heating anti-fog lenses, coated anti-fog lenses, anti-fog films, and anti-fog agents sprayed on the inner surface of the lenses before use. However, in actual use, these products and solutions still show more or less problems, and the main manifestation is that they cannot achieve the ideal defogging effect.

[0044] Based on this reality, through the understanding of the existing technology, the inventor believes that it is necessary to make changes to the status quo. Therefore, through research, a new anti-fogging protective device is proposed. The inventor believes that one of the main reasons for the fogging of existing goggles is that water vapor accumulates on the surface of the goggles and cannot be drained away normally, thus condensing into fog on the surface of the goggles. Therefore, in view of this, the inventor believes that how to reduce the accumulation of water vapor is an issue worthy of attention.

[0045] After research, the inventor proposed a pair of glasses legs to reduce the accumulation of water vapor. The glasses legs are provided with a channel, so that water vapor can be discharged through the channel, thereby reducing the accumulation of water vapor to a certain extent, and further reducing the problem of subsequent water vapor condensation and fogging.

[0046] See also Figure 1 and Figure 2The eyeglass leg includes a body 100 and a drainage tube 200. The body 100 is used to fix the goggles 300 as a whole on the user's head, and the drainage tube 200 is configured to drain the water vapor (in the example, the water vapor is discharged by generating negative pressure through suction). The following will be combined with the accompanying drawings to explain the eyeglass leg in the example in more detail.

[0047] See also Figure 1 In general, the main body 100 is a roughly elongated strip-shaped structure, which can be a long straight strip or a long strip with appropriate curvature in some parts. It can be either hard or soft. The hardness of the present application generally refers to a material that does not deform, especially under human power. As an example of hardness, it can be made of hard resin, plastic or metal. Softness generally refers to a material that is easily deformed, especially under human power. As an example of softness, the main body 100 can be made into a strap, such as a rubber strap or a cloth strap.

[0048] The elongated body 100 includes a first end 101 and a second end 102. Alternatively, it can be considered that the body 100 is formed by extending from the first end 101 to the second end 102. There are many options for the specific shape of the body 100. For example, in the structure of the goggles 300, the body 100 is a hard sheet structure, and relatively speaking, one end is large and the other end is small. When it is applied to glasses or goggles 300 and the like, the first end 101 of the body 100 is connected to the glasses frame 301, and the second end 102 of the body 100 can be used to attach the above-mentioned device to the wearer's head.

[0049] Furthermore, the temples of the glasses can also be used in conjunction with a fluid collection bag (not shown). As will be mentioned later, the temples of the glasses can be used in products such as glasses and goggles 300 to discharge the mist condensed by water vapor or fog and discharged through the drainage tube 200, and the fluid collection bag can temporarily store the discharged mist. The fluid collection bag can be fixed to the second end of the body 100 of the temple of the glasses, and the bag opening of the fluid collection bag accommodates the fourth end of the drainage tube 200 mentioned later (that is, the fourth end of the drainage tube 200 extends into the fluid collection bag through the bag opening).

[0050] See also Figure 4 and Figure 5, the drainage tube 200 is hollow, serving as a passage for gas flow, and is therefore used to discharge water vapor. In order to facilitate the description of the subsequent structure, the drainage tube 200 is defined as extending from the third end 201 to the fourth end 202. And corresponding to the structure of the body 100, the drainage tube 200 is installed in the following manner: the third end 201 to the fourth end 202 are arranged along the extension direction from the first end 101 to the second end 102 of the body 100, and the third end 201 matches the frame of the eyeglass frame 301. That is, in terms of position, the third end 201 of the drainage tube 200 corresponds to (is adjacent to) the first end 101 of the body 100, and the fourth end 202 of the drainage tube 200 corresponds to (is adjacent to) the second end 102 of the body 100.

[0051] In order to facilitate the discharge of water vapor, a negative pressure structure is selected in the example to be provided in the drainage tube 200, so that water vapor can be discharged relatively efficiently. In the example, the drainage tube 200 is provided with an operating section near the fourth end 202. Among them, "near the fourth end 202" is not a determined or specially defined position. In the exemplary use case of the goggles 300, the position may be the position corresponding to the ear of the wearer when the goggles 300 are worn. In other words, the operating section is between the third end 201 and the fourth end 202 of the drainage tube 200. Its specific position can be selected as needed.

[0052] In order to form a negative pressure structure, two one-way valves 204 are arranged in the operating section of the drainage tube 200. Figure 5 . A pressure ball 203 formed by the expansion of the tube wall is provided between the two one-way valves 204. The one-way valve 204 is one-way conductive from the third end 201 to the fourth end 202. The pressure ball 203 is soft and elastic, so it can be contracted by squeezing, and can also restore its original shape when the squeezing effect is reduced or eliminated. Therefore, the pressure ball 203 can be squeezed into a contracted state and can be restored from the contracted state when the squeezing effect is partially or completely eliminated. Based on the above structure, when the pressure ball 203 is pressed, the air in the pressure ball 203 can be transmitted through the part between the operating section and the fourth end 202, and then discharged from the fourth end 202; when the pressure ball 203 is released, the air in the part of the drainage tube 200 between the third end 201 and the operating section can be sucked into the pressure ball 203.

[0053] As for the specific arrangement of the drainage tube 200, it can be fixed on the outer surface of the body 100 or buried in the body 100 or partially buried in the body 100 (for example, the pressure ball 203 can protrude outside the body 100). In some examples, the drainage tube 200 is designed as follows: the fog in the protective glasses is affected by gravity, reaches the drainage tube through the lower frame of the frame, and is finally discharged through the back of the neck. Therefore, the installation position of the drainage tube 200 may be relatively low, for example, lower than the lower frame. At the same time, considering that the protective glasses are worn through the temples, the size of the temples may need to be designed to be an appropriate width so that the wearing operation above the ears can be provided at the same time and the fog can flow by gravity. Alternatively, in other examples, in addition to the small-sized temples, the protective glasses can also be designed with a binding strap / headband (not shown) as needed to fix the protective glasses. The headband can be designed to be elastic to improve the comfort of wearing.

[0054] When the drainage tube 200 is fixedly arranged on the outer surface of the body 100, it can be fixed by gluing or binding. When the drainage tube 200 is buried in the body 100, the body 100 can be made of a hard material, while the drainage tube 200 is made of a soft material. In addition, the body 100 is provided with grooves 103 distributed from the first end 101 to the second end 102 (see Figure 2 ), and the drainage tube 200 is removably embedded in the groove 103. In order to facilitate the removal of the drainage tube 200, the drainage tube 200 can be fixed in the groove 103 by magnetic adsorption or snap fastening. In an optional example, the cross-section of the groove 103 is an arc-shaped structure and the diameter is smaller than the outer diameter of the drainage tube 200. In this example, since the groove 103 is smaller than the drainage tube 200, and the body 100 is hard and the drainage tube 200 is soft, the drainage tube 200 can be snapped into the groove 103 by deformation.

[0055] Further, as a solution to enhance the stability of the drainage tube 200, the inner wall of the groove 103 is configured to limit the Figure 3 The ribs 104 shown are distributed from the first end 101 to the second end 102 (the length of the ribs 104 can be roughly equal to that of the body 100 or the length of the ribs 104 only extends to a portion of the length direction of the body 100). The ribs 104 can be a part of the body 100, that is, a solid protruding from the surface of the groove 103; or, the ribs 104 are independent of the body 100 and fixed to the body 100 by bonding, bolting, etc. Therefore, from the cross-section of the groove 103, the presence of the ribs 104 makes the groove 103 narrower at some positions, thereby preventing the drainage tube 200 from accidentally falling off due to non-human factors.

[0056] In addition, since the drainage tube 200 discharges water vapor mainly through the suction effect of negative pressure, the structural form of the rib 104 can also be adjusted. For example, the rib 104 is composed of an extrusion section and a limiting section. Among them, the extrusion section is adjacent to the first end 101, and the protrusion height of the extrusion section is greater than the protrusion height of the limiting section. "Adjacent" can be exemplarily represented as follows: two cylinders, both of which are arranged side by side and closely, and the two ends are aligned or not aligned. In this example, the relative positions of the ends of the two cylinders in the same direction can be considered to be adjacent.

[0057] In other words, the height of the rib 104 relative to the surface of the groove 103 is not uniform over the entire length direction. Therefore, in such an example, the drainage tube 200 is formed with a necking portion. That is, within its length range, its tube diameter (inner diameter) forms a transition characteristic from large to small and then from small to large. Therefore, through this structure, the drainage tube 200 can achieve a relatively greater suction effect, and can more efficiently suck water vapor.

[0058] As a supplement, an exhaust passage independent of the drainage tube 200 can be provided in the body 100 of the temple of the glasses. This can be achieved by removing part of the material of the body 100 to form a through hole therein or by burying a pipe in the body 100. The pipe can be used to balance the air pressure or to discharge water vapor. For example, for the closed covering goggles 300, the pipe can cooperate with the lens 302 part of the goggles 300 that surrounds the eyes, so that when the aforementioned lens 302 and the human face form a closed space, the water vapor therein is discharged through the pipe. In addition, by providing an additional exhaust passage, the frequency of use of the drainage tube 200 can also be reduced to a certain extent, thereby hopefully increasing the service life of the drainage tube 200, especially the service life of the pressure ball 203.

[0059] Having said that, through the above description, the structure and construction method of the glasses legs in the example have been described in detail. The following will explain the application examples of the glasses legs, such as glasses frame 301, glasses (cooperation of glasses frame 301 and lenses 302), and goggles 300.

[0060] See also Figure 6 , the glasses frame 301 includes a glasses frame, a wiper 305 and glasses legs (such as cloth straps, rubber straps). The wiper 305 and the glasses legs are both combined with the glasses frame. The glasses legs can be integrally formed with the glasses frame (such as goggles 300) or connected by bolts, pins, etc. (such as glasses).

[0061] The frame constitutes the main part of the eyeglass frame 301, and the frame includes two annular frames (corresponding to the left and right eyes of the human face, respectively) distributed on the left and right and connected to each other. The two annular frames constitute a physical structure for mounting two lenses. Each annular frame is composed of an upper frame body, a lower frame body 401, a left frame body, and a right frame body, and thus is generally annular in structure. In some other examples (such as Figure 6 The two annular frames can be integrally formed to form an integral structure, that is, the frame is substantially an annular frame. That is, the frame is composed of an upper frame body, a lower frame body 401, a left frame body and a right frame body, and the frame has good shape and fit to the face, and has good sealing and protection effect. The frame can be made of materials such as plastic, resin, and metal, and therefore has the characteristics given by the material.

[0062] Corresponding to the frame, the eyeglass frame 301 has two eyeglass legs, and the two eyeglass legs are respectively fixed to the left frame body and the right frame body of the eyeglass frame with the first end 101 of the body 100. When the frame of the eyeglass frame 301 is two annular frames, the first end 101 of the body 100 of one of the eyeglass legs is connected to the left frame body of one of the annular frames; correspondingly, the first end 101 of the body 100 of the other eyeglass leg is connected to the right frame body of the other annular frame. When the frame of the eyeglass frame 301 is a single annular frame, the first end 101 of the body 100 of one of the eyeglass legs is connected to the left frame body of the single annular frame; correspondingly, the first end 101 of the body 100 of the other eyeglass leg is connected to the right frame body of the single annular frame.

[0063] In addition, as one of the improvements of applying the glasses legs to the glasses frame 301, a flow accumulation groove 402 is provided on the lower frame body of the glasses frame, see Figure 8 . And correspondingly, the third end 201 of the drainage tube 200 in the temple of the glasses is connected to the accumulation groove 402. Therefore, when the accumulation groove 402 is injected with fluid, the fluid can also be discharged through the drainage tube 200. Considering the negative pressure structure design in the drainage tube 200, the liquid in the accumulation groove 402 can also be discharged through the exhaust channel (the exhaust channel in the body 100 of the temple of the glasses that is independent of the drainage tube 200). At the same time, after the liquid in the accumulation groove 402 is discharged, by operating the pressure ball 203 of the drainage tube 200, the airflow from the outside (relative to the space formed by the glasses and the face) can be actively drained through the exhaust channel to a certain extent. Furthermore, a desiccant can also be selectively provided in the accumulation groove 402, generally in the form of a strip, so it can also be called a drying strip.

[0064] Depending on the usage scenario and environmental requirements (such as medical protective eye masks), the exchange of airflow with the outside world can be limited, that is, the exhaust channel is not set (or the exhaust channel can be controlled to be opened or closed) and the liquid discharged from the drainage tube 200 is temporarily stored in a storage device that is tightly connected to it, thereby achieving isolation from the outside world while discharging the liquid, so as to avoid direct contact with contaminated air from the outside world.

[0065] As a matching structure of the flow trough 402, the spectacle frame 301 also includes the following Figure 6 The wiper 305 shown is rotatably mounted on the frame, and the rotating shaft is located at the upper frame, so that a downward sweeping action can be produced. Thus, the wiper 305 can achieve a scraping action by rotating. When the lens 302 is mounted on the eyeglass frame 301, the wiper 305 can wipe the surface of the lens 302, thereby removing water stains on the surface of the lens 302.

[0066] The structure of the wiper 305 may include a micro motor (electric motor) and a wiper blade. The micro motor is installed on the upper frame of the lens frame (implicitly installed, buried inside), and one end of the wiper blade is connected to the output shaft of the micro motor. Alternatively, the wiper 305 may also be combined with a gear structure to achieve transmission.

[0067] As another example of the application of glasses legs, Figure 6 As shown, the goggles 300 include a glasses frame 301 and a lens 302. The lens 302 is fixed by an upper frame, a lower frame, a left frame and a right frame. The legs of the goggles 300 are implemented in a band structure, for example, a rubber band 304 can be used.

[0068] In an alternative solution, the frame and lens 302 in the spectacle frame 301 are both integral structures, that is, the spectacle frame 301 includes one frame, and the lens 302 is also one. However, the frame covers both eyes, and the lens 302 also covers both eyes accordingly. As a result, the structure of the goggles 300 is simpler in appearance, and also has a larger visual range. And the lens 302 can also be integrally formed with the spectacle frame 301 to simplify its structure and avoid high complexity and easy damage.

[0069] The flow trough 402 (a desiccant may be optionally disposed in the channel) for discharging mist water may be designed to be strip-shaped and extend over the lower frame of the eyeglass frame 301. Furthermore, the lens 302 may also be provided with a guide channel 404, and the guide channel 404 is fluidically connected to the flow trough 402 (a cotton strip 403 or a desiccant may be optionally disposed in the channel; or, the cotton strip 403 and the desiccant may be disposed at the same time). In other words, in this example, the guide channel 404, the flow trough 402 and the drainage tube 200 are connected. Thus, the flow trough and the guide channel 404 may be constructed as a whole in a "T"-shaped channel, i.e., a T-shaped groove 405, see Figure 8 The mist water scraped off by the wiper 305 can be gathered into the guide channel 404, and then flow into the drainage tube through the accumulation groove.

[0070] In order to allow the water mist scraped by the wiper 305 to enter the flow collection groove more smoothly and orderly, the lens 302 is formed with a drain port 306 (the position where the water mist leaves the lens and enters the flow guide channel 404), and the drain port 306 is close to the edge of the lens 302 and adjacent to the flow collection groove 402. In addition, the surface of the lens 302 has a flow guide structure, such as Figure 7 The guide pattern 303 is shown. The size of the guide pattern 303 is limited to not blocking the user's field of vision during use.

[0071] The flow guide pattern 303 may include a plurality of flow guide ridges (or concave flow guide grooves in other examples), each of which is a streamlined structure and arranged so that the flow guide pattern 303 has a divergent portion and a convergent portion. The divergent portion is adjacent to the upper frame (below the end of the wiper 305), and the convergent portion is adjacent to the lower frame and converges to the drain port 306.

[0072] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
