Description

Technical Field

[0001] This utility model belongs to the technical field of eye protection equipment, and more specifically, it relates to an anti-fog goggles. Background Technology

[0002] A heat pipe is a heat transfer element with extremely high thermal conductivity. It transfers heat through the evaporation and condensation of liquid within a fully enclosed vacuum tube, utilizing capillary action to achieve compression cooling and heat transfer effects. It possesses high thermal conductivity and excellent heat transfer properties. Safety goggles, also known as protective glasses, are common eye protection equipment widely used in medicine, chemistry, and industry. In workplaces and operations where eye injuries are likely, workers often wear safety goggles to protect their eyes from direct contact with harmful substances, splashes of foreign objects, or mechanical impacts. Most existing safety goggles are made of synthetic materials, making them lightweight, durable, and offering good protection. However, in high-humidity environments or when moving from cold outdoor temperatures indoors, the temperature difference between the atmosphere and the goggle surface causes moisture to accumulate, forming condensation and impairing visibility, thus affecting the normal use of the goggles and operational safety.

[0003] For example, Chinese utility model patent with authorization announcement number CN 214858197 U discloses a multi-layer lens anti-fog goggles, which changes the original single-layer lens to a hollow multi-layer lens. It uses a small amount of gas sealed between the multi-layer lenses to form a heat insulation layer, which effectively reduces the heat conduction between the inner and outer lenses. However, its shortcomings are: by increasing the lens thickness, the lens becomes thicker, which affects the field of vision, and it is relatively troublesome to switch the lens back and forth when the hands are inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an anti-fog goggle.

[0005] To achieve the above objectives, this utility model employs the following technical solution: An anti-fog goggle includes a headband, a headband connector that mates with the headband, a face connector mounted on the headband connector, and a mirror mounted on the face connector. The headband connector has first heat pipes on both sides for maintaining the mirror temperature and preventing water vapor condensation, and the face connector has third heat pipes around its periphery for maintaining the mirror temperature and preventing water vapor condensation.

[0006] Preferably, a second heat pipe is provided below the headband connector to maintain the mirror surface temperature and prevent water vapor condensation.

[0007] Preferably, one end of the second heat pipe is attached to the skin, and the other end is facing the mirror.

[0008] Preferably, the first heat pipe is arranged horizontally or at an angle, with one end touching the skin and the other end facing the mirror.

[0009] Preferably, the first, second, and third heat pipes are all filled with phase change material. The heat pipes achieve rapid heat conduction through the heat generated when the wearer is wearing the device, thereby maintaining the surface temperature of the mirror above the ambient dew point temperature.

[0010] Preferably, the edge of the mirror is provided with an annular groove, and the third heat pipe is embedded in the annular groove and in close contact with the mirror surface, so as to achieve uniform heating of the surrounding area of ​​the mirror and prevent fogging at the edge.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting a first heat pipe on both sides of the headband connector, a second heat pipe at the bottom, and a third heat pipe embedded around the face connection, the heat from the wearer's skin contact point can be efficiently conducted to the entire mirror surface, keeping the mirror surface temperature above the ambient dew point temperature and effectively preventing water vapor from condensing into fog on its surface. 2. The heat pipes are arranged horizontally, obliquely, or vertically, with one end close to the skin to obtain heat and the other end facing the mirror surface to transfer heat. This fully utilizes the thermal conductivity of the heat pipes to achieve rapid and uniform heat distribution and improve the overall anti-fog effect. 3. A ring groove is set at the edge of the lens and a third heat pipe is embedded to ensure that the area around the lens can be fully heated, which solves the problem that traditional goggles are prone to fogging at the edges, and further improves visual clarity and safety of use; 4. This utility model relies entirely on the wearer's own heat for fog prevention, requiring no additional power supply device. It has a simple structure, low cost, and is easy to promote. In summary, this invention maintains the temperature of the goggles by embedding a heat pipe, preventing water vapor from condensing on the goggles and maintaining a good working field of vision. Moreover, it has a compact structure, practical functions, and is easy to use, and can be widely used in medical, sports, industrial protection and other scenarios that require anti-fog goggles.

[0014] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.

[0015] Example 1: like Figure 1-2 As shown, an anti-fog goggle includes a headband 1, a headband connector 4 that mates with the headband 1, a face-fitting portion 3 mounted on the headband connector 4, and a mirror 2 mounted on the face-fitting portion 3. First heat pipes 5 are provided on both sides of the headband connector 4 to maintain the temperature of the mirror 2 and prevent condensation. Third heat pipes 7 are provided around the periphery of the face-fitting portion 3 to maintain the temperature of the mirror 2 and prevent condensation. The first heat pipes 5 are arranged horizontally or obliquely, with one end against the skin and the other end facing the mirror 2.

[0016] Specifically, a third heat pipe 7 is embedded in the face joint 3 at the eye socket, bridge of the nose and other places that are in contact with the facial skin. The heat transfer characteristics of the heat pipe are used to transfer the body heat to the entire lens to maintain the temperature of the goggles and thus prevent water fog from condensing on the surface of the goggles.

[0017] Example 2: An anti-fog goggle differs from Embodiment 1 in that a second heat pipe 6 is provided below the headband connector 4 to maintain the temperature of the lens surface 2 and prevent water vapor condensation. One end of the second heat pipe 6 is attached to the skin, and the other end is directed towards the lens surface 2. Each heat pipe is arranged horizontally, obliquely, or vertically, with one end close to the skin to obtain heat and the other end directed towards the lens surface 2 for heat transfer. This fully utilizes the thermal conductivity of the heat pipes to achieve rapid and uniform heat distribution, thereby improving the overall anti-fog effect.

[0018] Furthermore, the first heat pipe 5, the second heat pipe 6, and the third heat pipe 7 are all filled with phase change material. The heat pipes achieve rapid heat conduction through the heat generated when the wearer is wearing the device, thereby maintaining the surface temperature of the mirror 2 above the ambient dew point temperature.

[0019] Furthermore, an annular groove is provided at the edge of the mirror 2, and the third heat pipe 7 is embedded in the annular groove and in close contact with the mirror 2 to achieve uniform heating of the surrounding area of ​​the mirror and prevent fogging at the edge.

[0020] The working principle of this utility model is as follows: The headband 1 and headband connector 4 work together to secure the goggles, maintaining a stable connection between the head and the goggles. The face connection 3 is where the goggles meet the face, ensuring a tight seal between the goggles and the external environment. Heat pipes are embedded around the face connection 3, at the skin-contacting part of the headband connector 4, and in the lower frame of the goggles. These heat pipes transfer heat from the body to the lens surface 2, maintaining the lens temperature and preventing condensation even in humid environments, thus achieving anti-fogging. This prevents condensation on the goggles when using them in high-humidity environments or when moving from a cold outdoor environment to an indoor environment, maintaining good visibility.
