Benefits of technology

[0014]In one aspect of the invention in addition to the valve a conventional one-way valve or the like can be formed on a different location of the dive mask for enhancing the defogging performance.

Problems solved by technology

However, fog or dew may form on the window (e.g., glass window) of the dive mask when diving or swimming.
Moreover, warm air may undesirably condense into liquid.
As a result, the diver's line of sight is blocked (i.e., blurry).
However, the second method is difficult to accomplish especially for inexperienced divers.
It is often that water enters the throat undesirably.
None of the above defogging methods are advantageous since they involve repeated, difficult actions.
Thus, how to manufacture a dive mask which allows a diver to effectively, easily defog during swimming or diving is still an important issue to be solved among dive mask manufacturers.
However, the provision of the valve can consume a relatively large space and its manufacturing is relatively complicated and expensive.
However, a diver may have difficulties of maintaining pressure balance between the nose and the ear cavity when diving.

Embodiment Construction

[0035]Referring to FIGS. 1 and 2, a first preferred embodiment of valve 20 the invention is shown. The valve 20 is mounted under a bottom of a nose enclosure 11 of a mask 10. The mask 10 is implemented as a dive mask as shown and known in the art. The mask 10 comprises the nose enclosure 11, a pair of windows 12, and a soft skirt 13. A portion of the face including the eyes and the nose is covered by the mask 10. Preferably, there is a small amount of water or even no water within a space defined by the mask 10 and the face when a diver submerges underwater during a dive. Therefore, water does not interfere with the eyes and the nose during diving.

[0036]The provision of the valve 20 aims at expelling water within the space defined by the mask 10 and the face. In the first embodiment, the valve 20 is curve and downward extends and then extends upward with its opening facing upward. Thus, water cannot enter the valve 20 (i.e., closed first state).

Abstract

A valve mounted on a dive mask is disclosed. The mask has a closed window frame, a soft skirt extending rearward from the window frame for defining a space between itself and the face of a diver wearing the mask, and one or two windows defined by the window frame. The valve is flexible, tubular and has a first opening at one end in communicating with the space, and a second opening at the other end. The second opening is blocked in an inoperative position and is adapted to open to expel water or air therethrough by increasing pressure in the space or by pressing both sides of the valve.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]The invention relates to dive masks and more particularly to an one-way valve for a dive mask with improved characteristics.[0003]2. Description of Related Art[0004]It is typical for a person (e.g., diver) to wear a dive mask when engaging in swim, deep diving, surface diving or other water activities. It is also typical for the dive mask having a nose enclosure. It is further typical for the diver to bite the mouth piece of a snorkel in addition to wearing the dive mask. Thus, the diver can breathe freely when diving or swimming by communicating air through the mouth piece and the breathing tube of the snorkel.[0005]However, fog or dew may form on the window (e.g., glass window) of the dive mask when diving or swimming. This is because there is a temperature difference between inside of the dive mask and outside water. Moreover, warm air may undesirably condense into liquid. As a result, the diver's line of sight is blocke...
