In the present invention, the pressurizing pump 8 and the heating member 15 are all supplied with dc power, which is determined by the overall power supply scheme of the brewing apparatus.

In this embodiment, the first temperature sensing element 13 is a sheathed needle thermistor, and is sealed and then directly contacted with water, and the resistance value of the first temperature sensing element 13 is detected through a program in the IC on the control circuit board 10, so as to control the water temperature. It should also be noted that there is also an error in the relationship between the resistance of the thermistor and the temperature of the water, which error should also be compensated by the algorithm so that the error is controlled within a reasonable error range for the temperature required to brew the coffee. Furthermore, although the essential function of the sheathed thermistor is to give a signal to the program on the IC to stop the programmed heating means when the water temperature reaches the temperature required for brewing coffee, which temperature is often much lower than the temperature to which the heating means and the brewing device itself should be damaged, in order to protect the heating means and the brewing device itself, a further said second temperature sensitive element 14 is necessary, which element is directly connected to the device to be protected and detects that the permissible temperature of the device lies below the critical value of the temperature causing its damage and transmits this temperature value as a signal to the IC, which is programmed for protection purposes.

Sealing between the various major components should generally be considered. If no special necessity exists among the parts of the water supply, the reliable sealing is required to ensure that the flow direction of the water flow conforms to the design purpose. For example, a reliable seal is required between the bottom of the coffee cup 2 and the outlet of the brewing chamber 5 to ensure that all brewed coffee can flow into the coffee cup 2, where a sealing ring is used for end or radial sealing. The inlet of the brewing chamber 5 needs to be sealed with the pressure pump 8 to ensure that all the pressurized hot water can flow into the brewing chamber 5 without leakage, and the bottom of the water storage chamber 4 should also be sealed with the pressure pump 8, which are all realized by sealing rings.

Examples of keys and instructions of the present embodiment are as follows: a 6 multiplied by 6 LED light touch switch, namely the control key 9, is used on the control circuit board 10;

b1 key: a cold water brewing key, after being pressed by a user, the cold water brewing key is heated to a specified temperature, a signal is given by the first temperature sensing element 13, and then the pressure pump 8 is automatically started until the water in the water storage bin 4 is pumped out;

b2 key: the hot water brewing key is pressed by a user, and then the pressurizing pump 8 is automatically started until hot water in the water storage bin 4 is pumped out;

l1 indicator light: indicating the working state of B1, wherein the color is blue, the heating is carried out slowly, the pump is started and quickly flashed, and the pump is extinguished after the heating is finished;

l2 indicator light: and the working state of the B2 is indicated, the color is blue, the pump is started and quickly flashed, and the system is extinguished after the pump is started.

Example two:

as shown in fig. 1, 5 and 6, the present embodiment is different from the first embodiment in that: in this embodiment, a rechargeable battery 18 is further disposed in the cup body 1, and serves as a working power supply, thereby facilitating outdoor use.

The remaining features of this embodiment are the same as those of the first embodiment.
