Title:
BREATHING DEVICE FOR SNORKELING
Document Type and Number:
WIPO Patent Application WO/2020/078162
Kind Code:
A1
Abstract:
A breathing device for snorkeling comprises a face mask (10), a first breathing tube assembly (20) and a one-way exhalation valve (30). The face mask (10) comprises an outer mask (11) and a breathing mask (12). The first breathing tube assembly (20) comprises a first breathing tube (21) and a one-way inhalation valve (22). The one-way exhalation valve (30) is connected to and installed at the outer mask (11) and the breathing mask (12). When a user inhales, the one-way inhalation valve (22) opens, and external air enters a breathing cavity (121) from the first breathing tube (21). When the user exhales, the one-way exhalation valve (30) opens, and exhaled air flows from the breathing cavity (121) to outside of the outer mask (11). The breathing device for snorkeling mechanically separates exhalation and inhalation, thereby ensuring that air in a breathing cavity is fresh, and enhancing safety of using the breathing device.
