The extracted beverage is tea beverage or coffee beverage or medicinal beverage. The soaking time is enough and then the soaking time is finished.

A fixed-time brewing mode: that is, the manufacturer introduces a fixed time on the controller 6 before the product leaves the factory, such as: 2 minutes, 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes and other fixed time software programs, after a user puts brewing substances into the filter bowl 5, the brewing mode is entered by selecting a corresponding time key on the controller 6, and after the soaking time is enough (finished), the filter bowl 5 is automatically lifted; the time is selected from common time, so that the use is convenient for users, and the temperature of the brewed water can be selected by users.

The brewing time is set by self: the time setting can also be selected and set by self, and is not necessarily selected according to the fixed time; for example: the Chinese medicinal materials are brewed for 20 minutes, the temperature can be set automatically, and the temperature of the brewed water can be selected automatically.

Selecting a brewing mode for brewing: before leaving the factory, a manufacturer introduces a brewing time software program of a common brewing substance type into the controller 6, and sets a key of a corresponding brewing substance type on the controller 6, for example, a tea brewing mode in which the brewing substance is introduced into tea leaves: the tea making time of the tea types is fixed, such as the Tie Guanyin tea making mode, the black tea making mode, the green tea making mode and the scented tea making mode, a user selects a corresponding key on the controller 6 according to the corresponding tea types to enter the tea making mode, and the filter cup 5 automatically rises after the soaking time is enough (finished). For example: the Tieguanyin tea making mode comprises the following steps: the required water temperature is 95 ℃, and the soaking time is 4 minutes. For example: a black tea making mode: the required water temperature is 90 ℃, and the soaking time is 3 minutes. For example: green tea making mode: the required water temperature is 85 ℃, and the soaking time is 2 minutes. For example: and (3) scented tea making mode: the required water temperature is 90 ℃, and the soaking time is 5 minutes. The tea type tea making mode can also be black tea, white tea, yellow tea, green tea (oolong), herbal tea, herb tea and the like, and is determined according to actual production.

Selecting a brewing mode for brewing: also comprises a coffee powder brewing mode, the required water temperature is 95 ℃, and the soaking time is 1 minute. The infusion is tea or flower or coffee or medicine; the soaking time is any time from 30 seconds to 60 minutes.
