Description

Technical Field

[0001] This invention relates to the field of eye protection technology, specifically an isolation and protective goggles. Background Technology

[0002] Currently, there are various protective and isolation goggles and glasses available on the market. Their structure generally includes an eyeglass frame, a fitting part made of soft material, two lenses mounted on the frame, and a headband worn over the head. The fitting part is ring-shaped, with its inner side fixed to the frame and its outer side located outside the frame, fitting snugly against the outside of the eye sockets after wearing. However, due to the existing fitting part, the lenses fog up after wearing, affecting the user's vision. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an isolation and protective goggle that eliminates fogging and ensures that the user has a sufficiently good field of vision.

[0004] The technical solution of the present invention is to provide an isolation protective goggle with the following structure, including an eyeglass frame, a fitting part made of soft material, two lenses mounted on the eyeglass frame, and a headband worn on the head. The fitting part is annular, with its inner side fixed to the eyeglass frame and its outer side located outside the eyeglass frame and fitting against the outside of the two eye sockets of the human body after being worn. A heating wire connected to a battery is provided in the cavity formed after the eyeglass frame and the fitting part are fixed.

[0005] The inner bottom edge of the eyeglass frame is provided with an annular fixing frame. The fixing frame squeezes and deforms the fitting part, so that the outer side of the fitting part is tightly fitted and fixed to the inner wall of the eyeglass frame and sealed. The inner wall of the fitting part is tightly fitted and sealed to the outer wall of the fixing frame.

[0006] The inner side of the fixed frame is provided with multiple embedded ends. The bottom surface of the fitting part near the lens is provided with through holes for the embedded ends to be inserted one by one. Each embedded end passes through a corresponding through hole, and the side wall of the embedded end and the inner side wall of the fitting part form a channel for clamping the heating wire.

[0007] The inner wall of the fitting part has a recess corresponding to each embedded end; a part of the heating wire bends and abuts against the bottom surface of the recess when passing through the recess, while the other part abuts against the side wall of the lens, so that the heat of the heating wire is directly transferred to the lens to heat and defog.

[0008] The inner edge of the fitting part is provided with a sealing edge that bends inward; the outer side of the sealing edge is in close contact with and seals the lens, and the inner side is in close contact with and seals the outer bottom surface of the fixing frame; the inner side of the sealing edge is provided with an annular groove, and the outer bottom surface of the fixing frame is provided with a first annular protrusion, which is engaged with and limited by the annular groove.

[0009] The bottom surface of the fitting part is provided with an annular protrusion. The annular protrusion abuts against the inner bottom surface of the eyeglass frame to seal it. There is a gap between the inner side of the annular protrusion and the outer side wall of the lens. This gap, together with the inner bottom surface of the eyeglass frame and the bottom surface of the sealing edge, forms a closed cavity.

[0010] With the above structure, the present invention has the following advantages compared with the prior art: Since the cavity formed after the eyeglass frame and the fitting part are fixed is provided with a heating wire connected to the battery, the heat generated by the heating wire can be transferred to the lens. After the lens is heated, the water vapor on the lens can be evaporated, thereby eliminating fogging and ensuring the user's vision.

[0011] As an improvement, the inner bottom edge of the eyeglass frame is provided with an annular fixing frame. The fixing frame deforms the fitting part by squeezing it and makes the outer side of the fitting part fit tightly against the inner wall of the eyeglass frame and seal it. The inner wall of the fitting part is tightly sealed against the outer wall of the fixing frame, thereby increasing the sealing performance of the inner cavity of the eye mask.

[0012] As an improvement, the inner side of the fixed frame is provided with multiple insert ends, and the bottom surface of the fitting part near the lens is provided with through holes for insert ends to be inserted one by one. Each insert end passes through a corresponding through hole, and the side wall of the insert end and the inner side wall of the fitting part form a channel for clamping the heating wire. The insert end not only serves to fix the fitting part and the eyeglass frame, but also serves to position the heating wire and fix the lens.

[0013] As an improvement, a recess is provided on the inner sidewall of the fitting part at the position corresponding to each embedded end; a part of the heating wire bends and abuts against the bottom surface of the recess when passing through the recess, while the other part abuts against the sidewall of the lens, so that the heat of the heating wire is directly transferred to the lens to heat and defog. The lens and the heating wire are in direct contact, which can increase the thermal conductivity, and the heating conduction is faster, resulting in a very good effect of eliminating fogging.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-5 As shown, the protective goggles of the present invention include an eyeglass frame 1, a fitting part 2 made of soft material, two lenses 3 mounted on the eyeglass frame 1, and a headband 4 worn on the head. The fitting part 2 is annular and is made of medical-grade silicone material. The inner side of the fitting part 2 is fixed to the eyeglass frame 1, and the outer side is located outside the eyeglass frame 1 and fits against the outside of the two eye sockets after wearing. The eyeglass frame 1, the fitting part 2, and the two lenses 3 form a sealed inner cavity behind the eyes and eye sockets after wearing. The top and bottom of the eyeglass frame 1 are respectively provided with ventilation channels, which are connected to the inner cavity and are provided with removable sealing caps. The outer edge of the fitting part 2 is provided with a flange that extends outward after wearing and a nose strip that fits against the nose. The nose strip protrudes along the direction close to the lens 3 after wearing.

[0022] A heating wire 6, connected to a battery, is installed inside the cavity formed after the eyeglass frame 1 is fixed to the fitting part 2. The battery can be built into or placed externally on the eye mask, and the heating time can be controlled by a control board that cycles through the power on at regular intervals.

[0023] The inner bottom edge of the eyeglass frame 1 is provided with an annular fixing frame 5. The fixing frame 5 squeezes and deforms the fitting part 2, so that the outer side of the fitting part 2 is tightly fitted and fixed to the inner wall of the eyeglass frame 1 and sealed. The inner wall of the fitting part 2 is tightly fitted and sealed to the outer wall of the fixing frame 8.

[0024] The inner side of the fixing frame 5 is provided with multiple insert ends 5.1. The bottom surface of the fitting part 2 near the lens 3 is provided with through holes for inserting the insert ends 5.1 one by one. Each insert end 5.1 passes through a corresponding through hole, and the side wall of the insert end 5.1 forms a channel for clamping the heating wire between the side wall of the fitting part 2 and the side wall of the fitting part 2. The outer side wall of the insert end 5.1 is in close contact with the side wall of the lens. Since the insert end 5.1 is made of soft material, it can better fix the lens 3, making the lens 3 more securely installed.

[0025] The inner wall of the fitting part 2 is provided with a recess 2.2 at a position corresponding to each embedded end 5.1; a part of the heating wire 6 bends when passing through the recess 2.2 and abuts against the bottom surface of the recess 2.2, while the other part abuts against the side wall of the lens 3, so that the heat of the heating wire 6 is directly transferred to the lens 3 to heat and defog.

[0026] The inner edge of the fitting part 2 is provided with a sealing edge 2.3 that bends inward; the outer side of the sealing edge 2.3 is in close contact with and seals the lens 3, and the inner side is in close contact with and seals the outer bottom surface of the fixing frame 5; the inner side of the sealing edge 2.3 is provided with an annular groove, and the outer bottom surface of the fixing frame 5 is provided with a first annular protrusion, which is engaged with the annular groove for positioning.

[0027] The bottom surface of the fitting part 2 is provided with a second annular protrusion 2.4. The second annular protrusion 2.4 abuts against the inner bottom surface of the eyeglass frame 1 and seals it. There is a gap between the inner side surface of the second annular protrusion 2.4 and the outer side wall of the lens 3. This gap, together with the inner bottom surface of the eyeglass frame 1 and the bottom surface of the sealing edge 2.3, forms a closed cavity.
