Automatic non-return tea maker

The invention relates to an automatic non-return tea maker, which comprises a tea liquid jar, a non-return valve device and a tea making jar; tealeaves are arranged inside a tea making chamber of a tea making jar, tea making liquid is poured into the tea making chamber to be contacted with the tealeaves through a funnel of the tea liquid jar, the tea making liquid level rises to produce a floating force for a non-return valve device floating body so as to push upwards a valve element and to open a valve hole, so the tea making liquid enters a tea liquid chamber of the tea liquid jar through the valve hole to make the tea when the required water quantity is reached; under the state that the tea liquid jar is re-covered by an upper cover, the tea making jar can be inverted upwards at any time, so the soaking of the tealeaves can be stopped by discharging the tea liquid from the tea making chamber into the tea liquid chamber; only when the tea liquid jar is inverted back upwards, the valve hole can be closed again by pushing down the valve element through the water pressure and by pulling down the valve element through the decreased weight of the floating body so as to prevent the tea liquid from flowing back into the tea making chamber, so a great amount of tea liquid is remained in the tea liquid chamber for use by taking out the tea liquid; and when infusing the tealeaves, the use of multiple cups and jars can be avoided, and no switches are required since the non-return can be realized through the backflow of the tea liquid, and the convenience of the tea making jar in operation and use can be improved.
