technical field

The utility model relates to a mask, in particular to a mask capable of removing moisture.

Background technique

Protective face shields are often used in underwater sports, land sports or industrial production activities as protection for the user's face. Taking swimming and diving masks (water goggles for short) as an example, please refer to FIG. 1 , which is a schematic diagram of a user wearing a water goggle A. This kind of water mirror A generally includes a cover body A1, a frame A2 and a mirror group A3. The cover body A1 of this kind of mirror A is attached to the face of the user, and covers the eyes and nose of the user, and forms an airtight inner space with the eyes and nose of the user (not shown). display), so that the eyes and nose are isolated from the water. Since the underwater mirror A can only protect the user's eyes and nose, and cannot further provide the user with breathing and ventilation, users who are engaged in underwater activities need to use another breathing tube B as an underwater environment. Breathing device. This breathing tube B usually has a tube body B1 and a waterproof device B2. The tube body B1 has two opposite ends, one end is the mouthpiece B11, and the other end is the inlet/exhaust port B12. The waterproof device B2 is arranged on the inlet/outlet. Air port B12. When used in an underwater environment, the user in the underwater environment bites his mouth on the mouthpiece B11, sucks and exhales gas (and/or water liquid) through the mouthpiece B11, and makes the gas pass through the tube located on the water surface. The waterproof device B2 at the other end of the body B1 exchanges gas with the outside world. Since the aforementioned water mirror is airtightly attached to the eyes and nose of the user's face, the gas exchange cycle cannot be performed, so the slightly hot air exhaled from the nose will cause a temperature difference between the inside and outside of the mask, and then make the mask's Condensation occurs on the inside of the lens, which hinders the user's normal vision during underwater activities.

Most of the existing methods for removing fog or condensed water (collectively referred to as defogging) are to take off the water mirror, put the water mirror into water to rinse the fogged mirror surface, and then wear the water mirror again. Because this type of defogging method needs to take off the water mirror, it is quite inconvenient for the user. In addition, some diving veterans do not take off the water goggle while wearing the water goggle, but turn the water goggle briefly in the water, so that there is a gap between the water goggle and the face, and the water outside the water goggle enters the water goggle Inside, let the water flow through the mirror surface to make it clear, and then use the nose to make a strong "jet" action to generate greater pressure in the water mirror, and the water liquid and part of the air in the water mirror will be released from the preset position. The one-way valve or other parts under the nasal mask are quickly discharged. However, this defogging method is prone to choking on water for beginners.

In view of this, how to improve the fogging problem of the above-mentioned protective mask in the use state is the direction that people in this technical field want to work hard on.

The cover body 10 is attached to the face of the user and wrapped around the frame 12, and the frame 12 is suitable for holding the mirror group 13, and the strap 14 can make the cover body 11 firmly and airtightly attached to the user face. Because there are many types of existing water mirrors, the water mirror shown in the accompanying drawings of the utility model is only one of them. In fact, any type of water mirror can be applied in the utility model. For example, the cover body 11 is usually made of soft materials such as silicone, which mainly covers the user's eyes and nose. The frame 12 is usually composed of a main frame and a sub-frame, and the lens group 13 is held by the frame 12 to provide users with good vision during underwater activities. Regarding the various changes and combination states between the frame 12 and the mirror group 13, reference may be made to the applicant's Taiwan Patent No. 096213120 application, which will not be repeated here.

Because the user's body temperature is usually higher than the temperature of the underwater environment, when the user is engaged in underwater activities and wears the underwater goggle 1, the temperature of the gas exhaled by the user's nose in the cover body 11 will be higher than that of the surrounding periphery of the cover body 11. Therefore, the water vapor in the closed space 60 is likely to condense into water droplets on the lens group 13 to cause fogging. However, since the water mirror 1 of the present invention has a ventilation structure 50 connected to the main body 10, it can introduce dry and low-temperature air from the outside to reduce the condensation of water vapor. For details, please refer to FIGS. 2 to 5 in combination.

Moreover, the material and shape of the vent tube 51 are not particularly limited, and any suitable state that can achieve the purpose of gas communication can be applied to this embodiment. In actual application, the ventilation structure can be designed to be detachable, which is convenient for users to install the ventilation structure on the body of the water mirror according to actual needs.

In a preferred implementation state of the present utility model, the ventilation structure 50 further includes a one-way valve 52 and a waterproof device 53, wherein the one-way valve 52 is arranged at the first end 511 of the ventilation pipe 51, or is arranged adjacent to the first The end part 511 can be used on the body 10 to guide the outside air into the airtight space 60 between the water mirror 1 and the user's face in one direction. On the other hand, the waterproof device 53 is arranged on the second end 512 of the vent tube 51, and its function is to only allow the outside air to enter the enclosed space 60 through the vent tube 51 and prevent the outside liquid from entering it. For details, please refer to the application No. 096213122 application and No. 096216223 application in Taiwan, China, which are owned by the same person, will not be repeated here.

As mentioned above, when the user wears the underwater mirror 1 of this embodiment to engage in underwater activities, the user can exchange gas with the outside world through the ventilation structure 50, and the kinetic energy of the guided gas comes from the inhalation of the user's nose. . In detail, when the user inhales through the nose, the humid and hot gas that originally existed in the closed space 60 of the water mirror 1 will be sucked into the user's lungs, and at the same time guide the relatively dry and low-temperature gas outside the ventilation structure 50 After entering the confined space 60 through the waterproof device 53 , the one-way valve 52 , and the ventilation pipe 51 , the lens group 13 in the water mirror 1 can achieve the effect of defogging, so as to maintain a good line of sight for the user.

Then please refer to FIG. 6 to FIG. 9 together, which show the second embodiment of the water mirror of the present invention. Same as the previous embodiments, the water mirror 1 of this embodiment also has a body 10 and a ventilation structure 50 , wherein the body 10 also has elements such as a cover 11 , a frame 12 , a mirror group 13 , and a belt 14 . Different from the previous embodiments, the ventilation structure 50 of this embodiment must cooperate with a breathing tube 70 to achieve the purpose of communicating with the outside air. Specifically, the ventilation structure 50 of this embodiment includes a communication pipe 55 , as shown in the figure, which is roughly a branched tubular body with a first connecting head 551 and a second connecting head 552 . Wherein the first connecting head 551 is connected to the breathing tube 70 , and the gas can be communicated to the outside through the connecting tube 55 of the breathing tube 70 . On the other hand, the second connecting head 552 is connected to the cover body 11 , or connected to one of the frame 12 and the mirror group 13 , so that the airtight space 60 of the water mirror 1 can communicate with the outside air through the communication pipe 55 .

In actual application, the connecting pipe can be designed to be detachable, which is convenient for users to install the connecting pipe on the body of the water mirror according to actual needs.

Secondly, the breathing tube 70 disclosed in this embodiment is substantially the same as the prior art. It usually has a tube body 71 and a waterproof device 72. The tube body 71 has two opposite ends, one of which is a mouthpiece 711, and the other end is a The inlet/exhaust port 712, the waterproof device 72 is arranged at the inlet/exhaust port 712. When used in an underwater environment, the user in the underwater environment bites his mouth on the mouthpiece 711, and directly sucks and exhales gas (and/or water liquid) from the mouthpiece 711, so that the gas passes through the mouthpiece located on the water surface. The waterproof device 72 at the other end of the tube body 71 performs gas exchange with the outside world and prevents the outside liquid from entering the breathing tube 70 . Different from the prior art, the breathing tube 70 applied to this embodiment has an opening 713 on the tube body 71 between the mouthpiece 711 and the inlet/exhaust port 712, and this opening 713 is suitable for being tightly connected to the first The connecting head 551 is used to guide the external air flowing in from the end of the inlet/exhaust port 712 into the connecting pipe 55, so as to substantially reduce the moisture inside the mask.

In other implementation states of this embodiment, the ventilation structure 50 further includes a blocking device 56 disposed at the first connector 551 or at one of the openings 713 of the breathing tube 70 to allow outside air to enter and prevent External liquid enters it. The blocking device 56 can also be disposed at the second connector 552 or on one of the main body 10 to replace the function of the waterproof device to allow outside air to enter and prevent outside liquid from entering inside.

As mentioned above, when the user wears the underwater mirror 1 of this embodiment to engage in underwater activities, the user mainly exchanges gas with the outside world through the breathing tube 70. 711 When inhaling, the outside air will enter the user's lungs through the waterproof device 72 and the tube body 71, and when exhaling, the gas will be discharged from the waterproof device 72 in reverse. When the user finds that water vapor condenses on the lens group 13 of the water mirror 1 and hinders the line of sight, the user can inhale the hot and humid air in the closed space 60 of the water mirror 1 into the lungs through the inhalation of his nose, and then The dry and low-temperature outside air outside the waterproof device 72 is introduced into the airtight space 60 of the water mirror 1 through the waterproof device 72, the inlet/exhaust port 712, the opening 713, the first connector 551, and the second connector 552, so as to substantially reduce airtightness. The humidity in the space 60 restores the clear state of the mirror group 13. Depending on actual needs, the user may repeat the above-mentioned inhalation of the nose several times to quickly restore the clear state of the lens group 13 .

It should be noted that when the user normally uses the breathing tube 70 to breathe, most of the exhaled gas will be directly discharged outside through the tube body 71 and the waterproof device 72, even if a small amount of exhaust gas enters the communication through the opening 713 The tube 55 and the closed space 60 of the mirror 1 cause the fogging phenomenon of the mirror 1. The user only needs to inhale the aforementioned nose to easily introduce dry and cold air from the outside to eliminate condensation on the mirror group 13. of moisture.

Based on the above, since the mask disclosed by the utility model has a ventilation structure that can guide external air, the user can easily inhale the hot and humid water vapor in the mask into the user's lungs through the inhalation function of the nose, and At the same time, it guides the dry and cold air from the outside into the airtight space between the mask and the user's face, so as to solve the fogging phenomenon caused by the temperature difference of the existing mask endoscope group and provide the user with a good line of sight.
