Kettle cover with pressure relief device

Abstract

The invention provides a kettle cover which comprises a water absorption element, a bottle cap, a water bottle cap and an opening element, wherein the water absorption element is provided with a waterabsorption head and an air leakage part; the air leakage part is provided with an air leakage valve; the water absorption element is arranged on the bottle cap; the water suction head and the air leakage part are exposed outwards; the bottle cap is locked on a bottle opening; the opening element is arranged on the bottle cap in a sliding and penetrating manner and is provided with an initial position and an acting position; one end of the kettle cover is pivoted to the bottle cover, the other end of the kettle cover is buckled and fixed by an opening element located at the initial position, and when the opening element is pressed to be located at the acting position, in order to enable the kettle cover to be separated from the opening element, the kettle cover is opened through elastic force of the water suction head, and meanwhile the opening element pushes the air leakage part to deform to enable the air leakage valve to be opened. Therefore, when a user presses the opening elementto open the kettle cover, the air leakage valve can be simultaneously linked to be opened to release pressure, water in the kettle is prevented from being sprayed out of the water suction head due topressure, and dangers and environmental pollution can be avoided.

Description

technical field [0001] The invention relates to a kettle lid, especially a kettle lid with a pressure relief device. Background technique [0002] When infants drink water, most of them use water bottles to drink water through straws. In order to allow infants to drink water while lying on their backs, the industry has developed an automatic straw set for use with water bottles. It is like the automatic suction pipe group of the No. M464178 patent feeding bottle of China Taiwan Announcement. It is mainly based on the setting of the gravity ball, as the kettle tilts or stands upside down, as the drink is pulled by the gravity, the suction hose is pulled and moved together, so that the baby can suck into the kettle at any angle drinks. However, when used with the kettle cover, the kettle cover will press the suction head of the water suction hose to bend and close the water suction head. When the kettle is filled with hot drinks, if the user opens the lid of the kettle, bec...
