Description

Heating type antifogging goggles

Technical Field

Background

The goggles are widely applied to scenes of medical use, industry, laboratories or outdoor sports and the like, have the functions of preventing dust, debris, liquid splashing, toxic gas or disease and bacteria and the like, and have the problem of fogging of lenses in the using process. There are two main sources of moisture that cause fogging of goggles, one from warm, humid air exhaled by the wearer and the other from perspiration and breathing of the skin within the goggles. The hot, humid air can coalesce into droplets when it encounters the relatively cool inner surface of the lens. Droplets of condensate may cause fogging of the inner surface of the lens, may seriously impair vision, risk operational errors, and may even be dangerous.

At present, the fogging problem is relieved mainly by strengthening the gas flow in the inner cavity of the lens, carrying out antifogging coating treatment on the lens or heating the lens. The mode of strengthening the gas flow can only slightly reduce the fog, and the mode of antifog coating treatment, its antifog effect is also not ideal, and its coating is damaged easily moreover, can lose partial regional defogging function and damaged department influences the sight. The way of removing the fog by heating the lenses is more efficient than the first two ways, and at present, the fog is removed by basically arranging heating elements such as resistance wires at the spectacle frame and heating the lenses by heat conduction. However, the lens is heated from the edge of the lens, the center of the lens is heated slowly, the fog elimination time is long, and if the resistance wire is arranged at the center of the lens, the sight of a user is obstructed.

Embodiments of the present disclosure are described below with reference to more specific examples.

Example 1

As shown in fig. 1 and 2, the antifog goggles of this embodiment include goggles body, lens 3, transparent electric heat membrane 4 of graphite alkene and bandeau 8, transparent electric heat membrane subsides 4 locate the internal surface of lens 3. The middle of the lens 3 is a nose bridge area, and the two sides are respectively a left side observation area and a right side observation area. The goggles body includes picture frame 1 and soft limit 2, and lens 3 is fixed through 1 inner groovy of picture frame and buckle. The headband 8 is provided with a power receiving part 7 at one side thereof, and the power source 6 can be placed in the power receiving part 7. Referring to fig. 2 and 3, the graphene transparent electrothermal film 4 includes a graphene film 43, electrodes (41,42) disposed on a surface of the graphene film 43, and an insulating protective layer 44 covering the graphene film 43 and the surfaces of the electrodes (41,42), wherein the electrodes (41,42) include an upper electrode 41 and a lower electrode 42, and widths of the upper electrode 41 and the lower electrode 42 are about 2 mm; the upper electrode 41 and the lower electrode 42 are connected to a power supply interface through a lead 5. With continued reference to fig. 3, the graphene film region between the upper electrode 41 and the lower electrode 42 forms a heating region of the transparent electrothermal film 4 (i.e. a region surrounded by thick black lines representing the upper electrode 41 and the lower electrode 42 and gray thin straight lines connecting the thick black lines on the left and right sides in the figure), the graphene film region located in the left observation region forms a left eye heating region of the transparent electrothermal film, the graphene film region located in the right observation region forms a right eye heating region of the transparent electrothermal film, and it can be seen from the figure that the left eye heating region and the right eye heating region are symmetrical and have substantially the same shape and area. The upper electrode 41 and the lower electrode 42 which are positioned in the left eye heating area and the right eye heating area are arranged in parallel, so that the heating uniformity is good, and the reliability is high. The temperature distribution of the left eye heating area and the right eye heating area is uniform and basically 36 +/-0.4 ℃ when the test is carried out at the room temperature of 25 ℃ and the voltage of 5V. The utility model discloses a transparent electric heat membrane's nose bridge heating zone is formed to the graphite alkene film region of nose bridge district position, and the lower electrode 42 that is located nose bridge heating zone is upwards protruding, and last electrode 41 is the sharp design, because the interval of last electrode 41 and lower electrode 42 in nose bridge heating zone reduces, and the temperature that generates heat in nose bridge heating zone risees gradually, and through the test, the highest temperature in nose bridge heating zone is 38.9 ℃. In addition, the area of the left eye heating area (or right eye heating area) of the electric heating film of the present embodiment is measured to be about 43% of the area of the left observation area (or right observation area) of the lens.

Example 2

Compared with the anti-fog goggles in embodiment 1, the anti-fog goggles in this embodiment are different in that the graphene transparent electrothermal film 4 shown in fig. 4 is used. Referring to fig. 4, the upper electrode 41 located in the heating area of the transparent electrothermal film is arranged in an upward-convex arc shape along the contour line of the graphene transparent electrothermal film, while the lower electrode 42 is arranged in a downward-convex arc shape at the portion located in the eye heating area and in an upward-convex arc shape at the portion located in the nose bridge heating area. Because the distance between the upper electrode 41 and the lower electrode 42 in the eye heating area is changed greatly, the graphene heating is not as uniform as the parallel electrodes in embodiment 1, and therefore the stability of the electrothermal film is slightly worse than the temperature of the electrothermal film in embodiment 1. The maximum temperature of the fever zone of the left eye was 39.3 ℃ and the minimum temperature was 31.2 ℃ as measured. In addition, because the part of the lower electrode 42 on the right side is shorter than the part on the left side, the area covered by the graphene film on the right side is smaller than the area covered by the graphene film on the left side, the area of the left eye heating area of the transparent electric heating film is larger than that of the right eye heating area, and the two sides of the transparent electric heating film generate heat unevenly. Because the area with larger area on the right side can not generate heat, and the heating area has a low temperature, the defogging effect of the antifog goggles of the embodiment is slightly worse than that of the embodiment 1.

Example 3

Compared with the anti-fog goggles in embodiment 1, the anti-fog goggles in this embodiment are different in that the graphene transparent electrothermal film shown in fig. 5 is used. Referring to fig. 5, the electrode structure of the graphene transparent electrothermal film 4 of the present embodiment is improved compared with the electrothermal film in embodiment 2, and the portion of the lower electrode 42 on the right side extends rightward, so as to increase the area covered by the graphene film on the right side, so that the area of the left eye heating area of the transparent electrothermal film is substantially the same as the area of the right eye heating area, and both sides of the transparent electrothermal film are equivalent to each other. Similarly, since the distance between the upper electrode 41 and the lower electrode 42 in the eye heating area is greatly changed, and the difference between the position with the largest distance and the position with the smallest distance is more than 60% through measurement, the graphene heating is not uniform as the parallel electrodes in embodiment 1, and the stability of the electrothermal film is slightly worse than the temperature of the electrothermal film in embodiment 1. Tests show that the maximum temperature of the eye heating area at the left side of the transparent electrothermal film 4 is 38.7 ℃, and the minimum temperature is 30.8 ℃. In addition, through measurement, the area of the left eye heating area (or the right eye heating area) of the electric heating film of the embodiment is about 68% of the area of the left observation area (or the right observation area) of the lens, although the electric heating film of the embodiment has a low temperature part, compared with embodiment 2, the electric heating film of the embodiment does not have a large area of area which can not heat, so that the visualization degree is improved to a certain extent compared with the antifogging goggles of embodiment 2.

Example 4

Compared with the anti-fog goggles in embodiment 1, the anti-fog goggles in this embodiment are different in that the graphene transparent electrothermal film shown in fig. 6 is used. Referring to fig. 6, the graphene transparent electrothermal film 4 of the present embodiment further improves the electrode structure compared to the electrothermal films of

embodiments

1 and 3. The upper electrode 41 located in the heating area of the transparent electric heating film is arranged along the contour line of the graphene transparent electric heating film, the upper electrode located in the heating area of the eyes and the distance between the lower electrodes are controlled, the lower electrodes 42 are designed in a gentle arc shape, the minimum position difference of the distance between the upper electrode 41 located in the heating area of the eyes and the maximum position of the distance between the lower electrodes 42 is smaller than 23 percent through testing, the temperature distribution of the heating area of the eyes is uniform, and the temperatures of the heating area of the left eye and the heating area of the right eye are basically 35.5 +/-0.6 ℃ through detection. In addition, through measuring, the area that the electric heat membrane left side eyes of this embodiment generate heat the district (or the right side eyes generate heat the district) is about 63% of lens left side observation area (or right side observation area) area, because the temperature in the district that generates heat of great area is close human temperature, can effectively defogging, and visual degree has had great improvement. The antifogging goggles of the present example balance the uniformity of heat generation and the goodness of sight, and have better improvement in vision than the antifogging goggles of example 1, and better uniformity of heat generation and improvement in use stability than the antifogging goggles of examples 2 and 3.
