A multifunctional mask for oxygen storage and atomization

Abstract

This utility model discloses a multifunctional mask for oxygen storage and nebulization, including a mask body, a two-way interface, a nebulizing valve, and a nebulizing tube. The two-way interface is located on the mask body and is equipped with an oxygen inhalation valve and a nebulizing valve. The oxygen inhalation valve is used to connect an oxygen storage bag and an oxygen tube. The nebulizing valve is equipped with an inlet and an outlet, and has a valve cavity inside, with a spring valve core at the upper end of the valve cavity. The nebulizing tube is used to interference fit the outlet nozzle of the nebulizer. The end of the nebulizing tube near the outlet is closed, and an opening is provided on the side wall of this end. This utility model, by setting a two-way interface on the mask body and setting a nebulizing valve on the two-way interface, and setting a spring valve core at the upper end of the nebulizing valve, allows the nebulizing tube to communicate with the inside of the mask body through the opening when inserted into the valve cavity of the nebulizing valve. At this time, the spring valve core above the valve cavity can be compressed and retracted. After nebulization is completed and the nebulizing tube is pulled out, the spring valve core can extend downward and block the inside of the inlet, thereby ensuring the sealing of the mask body.
