Title:
ISOLATION-TYPE DIVING MASK
Document Type and Number:
WIPO Patent Application WO/2020/037462
Kind Code:
A1
Abstract:
An isolation-type diving mask pertaining to the technical field of diving equipment. The isolation-type diving mask comprises a breathing tube (a) and a mask (b) having an inhaling channel (b1) and an exhaling channel (b2). The breathing tube (a) is internally provided with a partition plate (c) for dividing an internal space of the breathing tube (a) into an inhaling passage (a1) and an exhaling passage (a2). A top end portion of the breathing tube (a) is provided with an inhaling port (d) and an exhaling port (e). The inhaling port (d) communicates with the inhaling channel (b1) via the inhaling passage (a1). The exhaling port (e) communicates with the exhaling channel (b2) via the exhaling passage (a2). The inhaling port (d) and the exhaling port (e) are respectively located in regions at different sides of the breathing tube (a). In the isolation-type diving mask, the breathing tube (a) is provided with the inhaling port (d) and the exhaling port (e) located at different directional sides, and the inhaling port (d) and the exhaling port (e) respectively communicate with the corresponding inhaling passage (a1) and exhaling passage (a2) that are isolated from each other, such that a channel path through which fresh air flows into the mask (b) is completely isolated from a channel path through which exhaled air is discharged from the mask (b), thereby resolving the issue in which exhaled air is prone to mix with fresh air due to back-flow, facilitating regular breathing by a diver under water, and ensuring the diving mask is comfortable to use.
