[0042] The working principle of this utility model:
[0043] When in operation, the PTC cooling chip 15 is activated, and through the cooperation of heat conduction plate 14, heat conduction plate 2 16, blower 12 and cooling fan 17, circulating cold air is used to lower the ambient temperature of the cold chamber 11 to the specified low temperature.
[0044] After placing the filter assembly 42 into the rated coffee powder, put it into the coffee cup 41, open the refrigerator door 3, put the coffee cup device 4 into the cold compartment 11, and close the refrigerator 3;
[0045] After adding the rated ice-water mixture into the brewing chamber 61, close the brewing chamber lid 62, adjust the knob 51 of the brewing head assembly to the drip setting, drip it onto the filter assembly 42 containing coffee powder, and finally drip it into the coffee cup 41.
[0046] The sealed fermentation principle of this invention:
[0047] By installing the filter screen sealing ring 423, counterweight 424, rocker sealing ring 426, rocker 425, counterweight ball 427, and round tube 428 on the filter screen bracket 422, a filter screen assembly 42 sealing structure is formed. When placed in the coffee cup 41, the filter screen sealing ring 423 forms a seal with the coffee cup 41, which compresses the air in the coffee cup 41. The air will push the counterweight ball 427 through the round tube 428 to open the exhaust port 429 and exhaust the air, so that the air pressure inside the coffee cup 41 is consistent with the external atmospheric pressure. After placement, the counterweight ball 427 falls due to its own weight and forms a seal with the round tube 428 and the filter screen bracket 422.
[0048] The ice-water mixture in the brewing chamber 61 drips through the brewing head assembly 5 onto the filter screen 421 of the filter assembly 42, soaks the coffee powder, and then drips into the filter holder 422. When the weight of the coffee liquid in the filter holder 422 is greater than the total counterweight of the rocker arm 425 and the counterweight block 424 set in the filter holder 422, the rocker arm 425 opens the drip outlet 430, and at the same time, the internal air pressure pushes up the counterweight ball 427 to open the exhaust port 429 to exhaust the air, thus achieving a pressure balance.
[0049] Coffee liquid drips into coffee cup 41. When the weight of the coffee liquid in filter holder 422 is less than the total counterweight of rocker plate 425 set in filter holder 422, rocker plate 425 closes the drip outlet 430 under counterweight block 424. At the same time, counterweight ball 427 falls to seal the vent 429, thus achieving sealed fermentation of coffee liquid in coffee cup 41.
