Description

Technical Field

[0001] This application relates to the technical field of eyeglasses, and in particular to an eyeglass frame with an anti-fog ventilation structure. Background Technology

[0002] Glasses are prone to fogging in environments with large temperature fluctuations, such as when entering indoors in winter or wearing a mask, which affects visual clarity. Traditional solutions such as anti-fog sprays have short-lived effects and require repeated application. Anti-fog lenses are expensive and the anti-fog layer is easily damaged. Some electronic anti-fog glasses use lens heating technology, but this has problems such as high power consumption, uneven lens temperature distribution, and complex structure. Existing ventilated glasses are usually designed as a single piece, which makes it inconvenient to disassemble and assemble components when worn in environments where defogging is not required.

[0003] Therefore, those skilled in the art have provided an eyeglass frame with an anti-fog ventilation structure to solve the problems mentioned in the background art. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides an eyeglass frame with an anti-fog ventilation structure.

[0005] The eyeglass frame with an anti-fog and ventilation structure provided in this application adopts the following technical solution:

[0006] An eyeglass frame with an anti-fog ventilation structure includes an eyeglass frame body. An assembly hole is provided in the middle of the eyeglass frame body. A first tube is installed through the front and rear ends of the assembly hole. An air outlet strip is fixedly connected to the rear end of the first tube. The lower part of the air outlet strip's air duct is inclined towards the lens. A through hole is provided at the connection between the air outlet strip and the first tube. A second tube is installed inside the first tube. A filter is fixedly connected to the front end of the second tube. A motor is fixedly connected to the rear of the inner side of the second tube. An impeller is fixedly connected to the output end of the motor. Two metal strips are fixedly connected through the side wall of the first tube. A second elastic power contact is fixedly connected through the side wall of the second tube at a position corresponding to the metal strips. The second elastic power contact is connected to the motor's power terminal wire. An internally threaded tube is threadedly connected to the front end of the first tube.

[0007] Preferably, a battery is installed inside the temple of the eyeglass frame body near the rear end, a switch is installed on the temple near the front end, and a first elastic power contact is installed in the mounting hole corresponding to the position of the metal strip. The battery, switch and first elastic power contact are connected by wires in sequence.

[0008] Preferably, the second tube body has two symmetrically arranged mounting strips on its side wall, and the first tube body has a mounting groove on its inner side corresponding to the position of the mounting strips.

[0009] Preferably, the outer side of the internally threaded tube is provided with anti-slip protrusions, and a limit ring is fixedly connected to the front of the inner side of the internally threaded tube.

[0010] Preferably, a second magnet is fixedly connected to the front end and the sides of the air outlet strip, and a mounting hole is opened on the eyeglass frame body corresponding to the position of the second magnet, and a first magnet is fixedly connected in the mounting hole.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. Insert the first tube through the mounting hole, then insert the second tube into the first tube. Install the internally threaded tube at the front end of the first tube. Secure the second tube by pressing the mounting strip. The motor drives the impeller to rotate, drawing outside air into the second tube. The filter screen filters the air, which then enters the air outlet strip and is blown onto the lenses through the inclined airflow path, defogging them. The air outlet strip is positioned by the second magnet attracting the first magnet. The mounting strip, in conjunction with the mounting groove, positions the second tube. When the defogging function is not needed, reverse the internally threaded tube to detach it from the first tube, allowing the defogging component to be removed, reducing the weight of the glasses. The glasses frame provides ventilation and defogging, while the defogging component is easy to disassemble, reducing discomfort from pressure on the bridge of the nose. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figure 1-5 As shown, this application discloses an eyeglass frame with an anti-fog ventilation structure, including an eyeglass frame body 1. An assembly hole 5 is provided in the middle of the eyeglass frame body 1. A first tube 10 is installed through the front and rear ends of the assembly hole 5. An air outlet strip 7 is installed at the rear end of the first tube 10. The lower part of the air outlet strip 7 is inclined towards the lens. A through hole 8 is provided at the connection between the air outlet strip 7 and the first tube 10. A second tube 13 is installed on the inner side of the first tube 10. A filter screen 18 is installed at the front end of the second tube 13. A motor 15 is installed on the rear inner side of the second tube 13. An impeller 17 is installed at the output end of the motor 15. Two metal strips 11 are installed through the side wall of the first tube 10. A second elastic power contact 16 is installed through the side wall of the second tube 13 and at the position corresponding to the metal strips 11. The second elastic power contact 16 is connected to the power terminal wire of the motor 15. An internally threaded tube 19 is installed at the front end of the first tube 10.

[0022] The first tube 10 is inserted through the mounting hole 5. The air outlet strip 7 is positioned by attracting the first magnet 6 with the second magnet 9. The second tube 13 is inserted into the first tube 10. The mounting strip 14, in conjunction with the mounting groove 12, positions the second tube 13. The internal threaded tube 19 is threaded to the front end of the first tube 10 to fix the second tube 13. The motor 15 drives the impeller 17 to rotate. The impeller 17 draws outside air into the second tube 13. The filter screen 18 filters the air. The drawn-in air enters the air outlet strip 7 and is blown toward the lens through the inclined direction of the air outlet strip 7 to defog the lens.

[0023] like Figure 1 , 5 As shown, a battery 2 is installed inside the temple of the eyeglass frame body 1 near the rear end, and a switch 3 is installed on the temple near the front end. A first elastic power contact 4 is installed in the mounting hole 5 and at the position corresponding to the metal strip 11. The battery 2, switch 3 and first elastic power contact 4 are connected by wires in sequence. The battery 2 supplies power to the motor 15 through the first elastic power contact 4, metal strip 11 and second elastic power contact 16. The switch 3 controls the on and off of the circuit.

[0024] like Figure 2 , 3As shown, two mounting strips 14 are symmetrically arranged on the side wall of the second tube 13. An mounting groove 12 is provided on the inner side of the first tube 10 at the position corresponding to the mounting strip 14. The mounting strip 14 and the mounting groove 12 can limit the second tube 13, keep the second elastic power contact 16 in contact with the metal strip 11, and prevent the second tube 13 from deflecting and causing it to lose power.

[0025] like Figure 2 As shown, the outer side of the internally threaded tube 19 is provided with anti-slip protrusions, and a limit ring 20 is installed on the front of the inner side of the internally threaded tube 19. The anti-slip protrusions facilitate the rotation of the internally threaded tube 19, and the limit ring 20 can cooperate with the installation strip 14 to limit the second tube body 13.

[0026] like Figure 2 , 5 As shown, a second magnet 9 is fixed to the front end and the sides of the air outlet strip 7. The eyeglass frame body 1 has a mounting hole corresponding to the position of the second magnet 9. A first magnet 6 is installed in the mounting hole. The position of the air outlet strip 7 can be positioned by setting the second magnet 9 in conjunction with the first magnet 6.

[0027] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] The implementation principle of an eyeglass frame with an anti-fog ventilation structure in this application embodiment is as follows:

[0030] When in use, press the switch 3 on the temple of the glasses to turn on the circuit. The power of the battery 2 is transmitted to the motor 15 through the first elastic power contact 4, the metal strip 11, and the second elastic power contact 16. The motor 15 drives the impeller 17 to rotate at high speed, drawing in external air from the front end of the second tube 13. When the air flows through the filter 18 at the front end of the second tube 13, it is filtered of impurities. The filtered air is blown out through the air outlet 7 at the rear end of the first tube 10. Because the lower part of the air outlet 7 is tilted towards the lens, the airflow accurately covers the surface of the lens, quickly dispersing fog and water droplets to achieve physical anti-fogging. The second magnet 9 of the air outlet 7 is attracted to the first magnet 6 on the eyeglass frame body 1 to ensure that the air outlet and the lens are in a stable relative position. The second tube 13 is fixed by the mounting strip 14 embedded in the mounting groove 12 of the first tube 10. The internal thread tube 19 is tightened to the front end of the first tube 10, and its limiting ring 20 presses the mounting strip 14 on the second tube 13 to form a stable assembly. The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
