Abstract

A mouth mask includes a base frame member configured to fit the curvature of a human face, a shade fastened to the base frame member to form with the base frame member a curved surface for covering over the user's mouth and nose and having a notch on the middle part of the top side thereof around the user's nose to enhance wearing comfort, a chin support directly and angularly adjustably coupled to the base frame member or vertically and angularly adjustably coupled to the base frame member by means of an adapter member and defining with said base frame member an air hole for guiding out the user's exhaled air, and a set of ear loops respectively connected to the two ends of the base frame member for hanging on the user's ears.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a mask means for covering over the mouth and nose of a person to prevent spit flying and more particularly, to a mouth mask, which allows replacement of the shade and adjustment of the elevation and tilting angle of the chin support.[0003]2. Description of the Related Art[0004]Many mouth masks are commercially available for wearing by a person to prevent spit flying. According to conventional designs, the shade and chin support are arranged on one same axis. However, as the chin shape and length and the distance between the chin and the nose vary widely between people, the shade may be kept in close contact with the user's mouth and nose, affecting the user's speech clarity. In this case, the user's eyeglasses may fog up, interfering with the user's sight and breathing smoothness.SUMMARY OF THE INVENTION[0005]The present invention has been accomplished under the circumstances in view. It...
