Description

Technical Field

[0001] The invention relates to the technical field of tea brewing devices, in particular to a steam pressure tea brewing machine. Background Art

[0002] Drinking tea is part of traditional culture. Proper tea drinking can help metabolism and has the effect of refreshing the mind. There are many types of tea, such as Chinese green tea, white tea, yellow tea, oolong tea, black tea, black tea, scented tea, etc., Japanese tea sets such as sencha, tea dew, matcha, powdered tea, fragrant tea, Peicha, brown rice tea, etc., and black tea is divided into Darjeeling tea and Sri Lankan tea according to the producing area. Due to different types of tea, the suitable water temperature for brewing is not the same. The water temperature for brewing tea must be controlled according to the characteristics of the tea to fully bring out the color, aroma and taste of the tea. For example, the suitable water temperature for green tea is about 75℃-80℃ to prevent the high temperature from causing the aromatic substances of green tea to evaporate quickly; the suitable water temperature for white tea and yellow tea is about 80℃-85℃; the suitable water temperature for oolong tea is about 90℃-95℃; the suitable water temperature for scented tea is about 85℃; the suitable water temperature for black tea and black tea is about 95℃-100℃. If the water temperature is not properly controlled, the drinking taste and aroma will be significantly reduced. The water temperature for brewing tea must be controlled according to the characteristics of the tea in order to fully bring out the color, aroma and taste of the tea.

[0003] The traditional way of brewing tea is to use a ceramic pot, put tea leaves in the pot, and pour hot water to soak for a period of time to release the color, aroma and taste of the tea leaves before pouring it out for drinking. However, this method is time-consuming and inconvenient, and the water temperature difference during the soaking process is too large, and it is difficult for people with insufficient tea brewing experience to brew good tea. Later, automatic tea brewing machines appeared on the market, but the water pumps in these machines are particularly easy to be blocked by tea leaves, affecting the user experience. Summary of the invention
