Anti-overflow teapot lid with pressure relief barrel

Abstract

The invention discloses a water overflow preventing teapot lid with a pressure relief cylinders, which relates to the teapot lid. According to the teapot lid, an annular bulge (7) is arranged on the outer edge of the teapot lid; a necking annular cylinder (8) is arranged at the lower part of the annular bulge; upper ends of at least three elastic clamping sheets (9) are fixedly connected with the lower end or inner face of the lower part of the annular cylinder; at least two openings (6) are arranged around a handle of the teapot; outer walls of at least two cylinder bodies (4) of the pressure relief cylinders are in clearance fit with inner walls of the openings; a plurality of pressure relief holes (3) are formed in the cylinder bodies; anti-drop outwards turned plates (5) are arranged at the lower ends of the cylinder bodies; plate bodies (1) are arranged at the upper ends of the cylinder bodies; diameters of the plate bodies are larger than that of the openings; and the pressure relief holes in the cylinder bodies form pressure relief exhaust passages. According to the teapot lid, the openings formed in the teapot lip are closed by the arranged pressure relief cylinders to guarantee the temperature of the water can not be lowed; the pressure relief cylinders are lifted by water vapour to form the exhaust passages, so as to achieve the purpose of large displacement pressure relief, and to effectively reduce water overflow phenomenons.

Description

【Technical field】 [0001] The invention relates to a teapot lid, in particular to an overflow-proof teapot lid with a pressure relief cylinder 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 of...

Problems solved by technology

[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 the steam and boiling water can easily lift the lid, resulting in danger; for the existing defects of the lid, there are It is necessary to improve the structure to form a pot cover that can prevent overflow and prevent safety accidents.
