Flowing tea or coffee maker

Abstract

The invention discloses a flowing water tea or coffee brewing pot, which comprises a pot body, a pot cover body, and a tea powder cover. The pot cover body is provided with a control mechanism capable of closing or opening the water flow channel; The control and air intake system are independent of the air intake control; the container space is equipped with a first layer of filter screen; the container space is equipped with a dispersing water component that can disperse the water that enters the container space from the water flow channel; the tea outlet is located at the second Above a layer of filter net; the end of the conduit located in the kettle body is connected with a one-way valve that can only allow air to flow into the kettle body, so as to realize the automatic air intake of the air intake system. It can maintain the balance of the air pressure in the kettle body, no negative pressure will be generated, and the water will flow smoothly. It can avoid residual water remaining in the container space. The air intake system, water flow control structure, and tea outlet hole structure form a smooth water tea extraction system, which can effectively and accurately extract the excellent flavor components in tea or coffee, and avoid excessive precipitation of miscellaneous flavors and harmful substances.

Description

technical field [0001] The present invention relates to a pot, which can be used for extracting tea or brewing coffee. Background technique [0002] In the prior art, tea or coffee is brewed for a long time, which may lead to variation in taste or excessive precipitation of undesirable substances. For example, long brewing of tea will lead to excessive extraction of miscellaneous flavors, and the precipitation of harmful substances such as theophylline and tannic acid.

AI Technical Summary

Problems solved by technology

In order to get fresh tea, it is a systematic process to flow water from the water channel to the container space, soak the water with the tea in the container space, and then the tea flows out from the container space. This pot provides consumers with a new way of drinking tea. However, 1) due to simultaneous control of water outlet and air intake, negative pressure is easily formed in the kettle body, resulting in unsmooth water outlet

2) Residual water soaking destroys the quality of tea soup

3) Backflow causes tea scale in the pot

4) There may be air pressure in the container space, which may cause spraying, resulting in personal safety problems
