Abstract

The invention provides a double-circulation snorkeling mask. According to the technical scheme, the single-pipe air inflow is adopted, when a user inhales, oxygen or external air can enter an air inlet channel through an air channel, and due to the fact that the air inlet channel is formed in the edge of the outer mask, the layout of the air inlet channel of the double-circulation snorkeling maskcan be effectively optimized. The oxygen or external air enters a breathing cavity through the air inlet channel, and a mouth and a nose in the breathing cavity can directly inhale the oxygen or the external air. An expiration one-way valve is embedded in the cavity wall of the breathing cavity; the expiration one-way valve is communicated with an exhaust port; during inspiration, the expiration one-way valve is closed; the external air enters the breathing cavity through the air channel and the air inlet channel in sequence, during exhaling, the exhaling one-way valve is switched on, exhaledair is exhausted to the outside of the outer mask through the exhaust port, and the situation that the concentration of nitrogen dioxide in the breathing cavity seriously exceeds the standard and threatens life due to the fact that carbon dioxide exhaled by a human body is mixed with inhaled air or oxygen is avoided.

Description

technical field [0001] The invention relates to the technical field of diving, in particular to a double-cycle snorkeling mask. Background technique [0002] Diving, as a recreational sport, is favored by more and more people who enjoy being in the water. Snorkeling rebreathers help people breathe freely during diving and are essential equipment for diving sports. [0003] At present, there are mainly two types of snorkeling respirators commonly used: one is a mouth-biting respirator, which needs to be ventilated by opening the mouth, which not only easily causes the respirator to fall off, but also easily causes breathing difficulties caused by water ingress. The other is a full-dry respirator, which uses the same breathing tube to form an inhalation channel and an exhalation channel in the tube for inhalation and exhalation. However, in the case of inhalation, the exhaled carbon dioxide cannot be completely discharged in time , making the inhaled air and exhaled carbon d...
