Full-face mask

Abstract

A full-face mask, including a mask body, a breathing tube, an unfolded isolation support portion, at least one intake valve and at least one isolation plate, is provided. The mask body fits an user's face via a soft portion to form an interior space. The breathing tube is disposed on the mask body and is connecting with the interior space. The unfolded isolation support portion is disposed in the inner space and completely fits and covers the cheeks and the nose of the user to define an upper space and a lower space. At least one intake valve is disposed on the unfolded isolation support portion. A guide plate is disposed in a channel. Thus, the user could effectively breathe and exhale the air, and could isolate the face from the water leaking into the full mask to avoid danger.

Description

FIELD OF THE INVENTION[0001]The present invention provides a full-face mask for underwater activities. In particular, it provides a full-face mask for snorkeling which can improve safety.DESCRIPTION OF THE RELATED ART[0002]For a long time, breathing equipments used for underwater activities all adopt a design in which a mask is separated from the breathing tube, wherein the mask covers the eyes and the nose with an airtight design. The breathing tube is nipped by the mouth forcing the user to inhale / exhale air therethrough. In other words, this kind of breathing equipment for underwater activities will comprise at least two portions, i.e., a “mask” and a “breathing tube”, which may be cumbersome to carry.

Problems solved by technology

In other words, this kind of breathing equipment for underwater activities will comprise at least two portions, i.e., a “mask” and a “breathing tube”, which may be cumbersome to carry.

Moreover, the fixed relationship between the two portions should be taken into consideration, so the wearing thereof is also time-consuming Additionally, for use, it is necessary to change the habit of breathing through the mouth and the nose into compulsory breathing through the mouth, which could only be achieved through training Especially when water accidentally enters the mask or the breathing tube, the nose or the mouth needs to compulsorily exhale to drain the water away, or the breathing tube needs to be taken off to clear water and be then nipped again by the mouth.

These actions are quite complicated for users and it is not easy for users to adapt to these actions.

For beginners or people who are afraid of water, these actions are more difficult, which increases the chance of inhaling water, has poor safety, and greatly reduces the fun of leisure activities.

However, since the mouth and the nose are in the same space, carbon dioxide can easily accumulate and cause dizziness and fainting or the user may hyperventilate due to anxiety caused by water accumulation in the mask or the like, if the channel for the inhaled / exhaled gas is not smooth, the ability to block water inflow is not good, and the drainage design is not stable.

This is worse than the risks of the design with separate parts.

If the user encounters the above-mentioned conditions when wearing the full-face mask, the user may face the fate of drowning whether the user continues to wear the mask or completely removes the mask, which is quite dangerous.

The design defects causing the above risks are very subtle.

Common consumers have no ability to distinguish these design defects when buying the masks until it is too late when danger occurs in use.

This seemingly reasonable theoretical design actually hides great flaws.

However, this design cannot be completely fit or cover the cheeks and the nose of the user.

That is, when such a full-face mask is worn, many gaps will be formed between the isolation portion 110 and the cheeks and the nose of the user.

Therefore, the design of the air passages also seems to be redundant and does not achieve the expected effects.

The amount of clean air entering the nose and the mouth is naturally insufficient.

In addition, in the case where the air intake is insufficient, the exhaust gas exhaled is mostly discharged through the gaps.

Thus, the danger of inhaling water or hyperventilating due to anxiety is likely to occur because the water cannot be discharged in time.

The result of insufficient air intake and inability to discharge water indeed is a serious threat to life safety.

However, this has caused many fatal accidents in recent years.

However, as mentioned above, the conventional full-face masks have a number of technically fatal designs (i.e., the actual gas circulation path is obviously different from what is expected in theory, and thus, the intake of clean air and the discharge of carbon dioxide fail to meet the standard), so it is almost impossible for these masks to pass the EN 136: 1998 test standard.

These fatal designs belong to potential hazards and consumers have no ability to find technical defects from the appearance of the masks.
