Anti-overflow teapot lid with pressure relief cover

Abstract

The invention discloses an anti-overflow teapot lid with a pressure relief cover, and relates to a teapot lid. A hand shank (1) is arranged on the middle part of the teapot lid (4); an annular bump (5) is arranged at the outer edge of the teapot lid; a necking annular cylinder (6) is arranged at the lower part of the annular bump; the upper ends of at least three elastic blocking plates (8) are fixedly connected with the lower end or the lower inner surface of the annular cylinder; at least two openings (9) are formed in the periphery of the hand shank of the teapot lid; at least two pressure caps (3) are respectively buckled on the openings; one side of each hand shank of at least two pressure caps is hinged with the teapot lid through a shaft coupling (2); and the openings in the teapot lid form a pressure relief exhaust channel inside the teapot. A vapor exhaust channel is formed by the openings arranged on the teapot lid; and ascending vapor is rapidly discharged by opening the pressure caps along the exhaust channel formed by the openings when the pressure of the vapor inside the pot is overlarge. Thus, the large-displacement pressure relief target is achieved; and the overflow phenomenon is effectively reduced.

Description

【Technical field】 [0001] The invention relates to a teapot cover, in particular to an overflow-proof teapot cover with a pressure relief cover for a kettle. 【Background technique】 [0002] It is well known that once the water temperature of the kettle reaches or approaches 100 degrees, the impact of water vapor will easily cause the lid of the kettle to rush upwards, and the boiling water will overflow along the upper mouth of the teapot, and the overflowing water will extinguish the liquefaction. gas so that the gas accumulates in the room, and once it encounters an open flame, it will explode and cause adverse consequences; this is due to the design defect of the existing pot lid. The pressure cannot be released quickly, and there is no constraint between the lid and the upper mouth of the teapot, so water vapor and boiling water can easily lift the lid up, resulting in danger; for the existing defects of the lid, there are It is necessary to form a kettle cover capable o...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies in the background technology, the present invention discloses an anti-overflow teapot cover with a pressure relief cover. The opening on the cover is used to form an exhaust passage for water vapor. When the pressure of water vapor in the kettle is too high, the upward The water vapor will be quickly discharged from the pressure cover along the exhaust passage formed by the opening to achieve the purpose of large displacement pressure relief and effectively reduce the occurrence of water overflow
