Title:
SPRAY CORE AND OXYGEN INJECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/083118
Kind Code:
A1
Abstract:
A spray core (100) and an oxygen injection apparatus. The spray core (100) comprises a housing (110), a movable member (120), and an insertion pin (130); the housing (110) is internally provided with an accommodating cavity (111), and an atomization opening (112) is formed in one end of the housing (110); the movable member (120) is arranged in the accommodating cavity (111) in a reciprocating mode facing or away from the atomization opening (112), the movable member (120) is internally provided with a cavity (121), and a water spraying opening (122) is formed in the movable member (120); the insertion pin (130) is inserted in the cavity (121), the length direction of the insertion pin (130) is consistent with the moving direction of the movable member (120), a first end of the insertion pin (130) is fixedly arranged on the housing (110), and a second end of the insertion pin (130) can be inserted into the water spraying opening (122). When the movable member (120) moves towards the atomization opening (112), a gas supply device supplies gas to the accommodating cavity (111), and liquid in a liquid supply device sequentially flows through the cavity (121), the water spraying opening (122) and the accommodating cavity (111), is atomized under the action of the gas and is sprayed out from the atomization opening (112). When the movable member (120) moves away from the atomization opening (112), the insertion pin (130) is inserted into the water spraying opening (122) so as to limit liquid in the cavity (121) from entering the accommodating cavity (111). In the moving process of the movable member (120), the insertion pin (130) can dredge the water spraying opening (122), and the water spraying opening (122) is prevented from being blocked, so that the problem that the water spraying opening (122) is blocked is effectively solved.
