Abstract

The invention discloses a water heater with an automatic power off function. The water heater with the automatic power off function is provided with a bottle plug, wherein the bottle plug is provided with an accommodating area; a first contact, a second contact, a reset switch and an automatic power off device are arranged in the accommodating area; and the first contact and the second contact are switched off by the automatic power off device. The electric water heater is powered off automatically through the automatic power off device, and is safe; an ablation phenomenon in a water heating bottle can be prevented effectively; the water heater cannot be automatically reset or electrified under any conditions after being powered off through the automatic power off device, and is safe; the reset switch is arranged in the accommodating area; when water is required to be heated again, the reset switch is switched on, and the water heater is convenient; the automatic power off device consists of a lever contact plate and a pressing device; and the pressing device consists of a pressing plate and an expansion pushing device. In an automatic power off process, the sensitivity and the reliability of the water heater are high owing to the simple structure; shirt-circuiting of a conductive element in the accommodating area can be effectively avoided by an expansion air bag; and a pressure environment in the water heating bottle can be stable in a heating process.

Description

technical field [0001] The invention relates to a water heating device, in particular to an automatic power-off water heater. Background technique [0002] The water heater currently on the market that can be installed on a flask or a thermos is an aluminum-clad nickel-chromium wire tube heating element, which is installed on a cork or plastic bottle stopper, inserted into the thermos bottle, and then connected to the outside with a wire. The power supply heats the water in the bottle. This kind of heater is easy to use, but because there is no automatic power-off device after the water is boiled, it is easy to burn out the heater when no one cuts off the power supply, and if it is serious, the water will be boiled dry, causing a fire. [0003] Further, the patent with the authorized notification number CN2750753 discloses a fully automatic anti-dry heating electric speed heating device for a hot water bottle. The technical scheme adopted is as follows: The shell is hollow...
