Description
(1) technical field
The present invention relates to a kind of commodity, particularly a kind of thermos flask.
(2) background technology
Thermos flask plays a very important role in the life of people, but general thermos flask, and for various reasons, kettle plug can often fall on the ground because of carelessness.Particularly during dress hot water, kettle plug easily ejects because pressure in kettle is excessive, have impact on heat insulation effect, brings a lot of inconvenience to the life of people.
(3) summary of the invention
The present invention, in order to make up the defect of prior art, provides the thermos flask that a kind of kettle plug not easily drops.
The present invention is achieved through the following technical solutions:
A kind of thermos flask, comprise pot lid, kettle plug, shell, it is characterized in that: the inner surface of described pot lid top end face is provided with a pot lid magnet, on described kettle plug top end face, opposite position is provided with a kettle plug magnet, and the described kettle plug magnet magnetic pole corresponding with pot lid magnet is homopolarity.Edge, described shell aperture place is provided with a circle plastic ring, is provided with several shell magnet at plastic ring medial surface, and the outside magnetic pole of described shell magnet and the upside magnetic pole of kettle plug magnet are heteropole.Described kettle plug is connected by cord with plastic ring.
The invention has the beneficial effects as follows:
Because pot lid magnet is just identical to polarity with kettle plug magnet, show as repulsion, kettle plug will tightly be pressed in the kettle mouth of kettle body, can not eject, and when can prevent that in kettle, pressure is excessive, kettle plug ejects.Because kettle plug magnet is just different to polarity from shell magnet, show as gravitation, draw with cord one during pouring, kettle plug is just fixed on plastic ring not easily to have fallen.
