Description

[Detailed Description of the Invention] The present invention relates to a pneumatically pumped pot in which liquid in the bottle, such as hot water, is poured out of the bottle using compressed air from an air pump.

In order to eliminate the drawback of this type of conventional device where hot water boils on the human body and causes burns due to incorrect operation of the button, the inventors have already created a groove or other drop on the top surface of the button that presses the air pump. , an automatic locking plate whose tip is engaged with the bush button is provided, and a spring is provided to hold the locking plate on the upper surface, so that when the automatic locking plate is twisted against the spring, the locking plate is rotated. If the protrusion comes off the stopper, the tip of the automatic locking plate will close the top opening of the air pump via the check valve, so even if an elderly person or child accidentally presses the button, the hot water in the bottle will not leak out. Although we devised a safe air-feeding pot that does not leak, the structure is such that hot water will not flow out if the button is pressed while the automatic lock plate is not twisted against the spring, resulting in some demand. The problem was that the operator mistakenly thought that the pneumatic pot was malfunctioning.

In order to eliminate such misconceptions among some users, we have devised a pneumatic pot that is safe, functionally superior, and easy to manufacture.

That is, according to the present invention, the button for pressing the air pump is automatically locked in normal conditions to prevent the button from lowering, and the button is engaged in the button when in use. When the automatic lock plate is twisted, the lock of the button can be released and the button can be lowered.
