The detailed working process of the portable card-grinding cup is as follows:
when a heating body 1-2 of the heating container 1 starts to heat, the temperature of liquid in the water tank 1-1 is lower, the expansion and gasification of the liquid are smaller, a small amount of gas is upwards discharged through an air channel 2-5 of a valve core 2-4, and the gas is discharged to the outside of the mocha cup after passing through a blocking hole 3-3, a gas channel 3-6 and an exhaust hole 3-7; the valve core 2-4 stays at the lower position in the first valve seat hole 2-6 of the powder bearing device 2 under the action of gravity; the heating body 1-2 continues to heat, when the temperature of the liquid in the water tank 1-1 is higher, the liquid expands and gasifies greatly, a large amount of gas can not be discharged upwards through the air channel 2-5, the air pressure below the valve core 2-4 rises, the valve core 2-4 is jacked upwards by the higher air pressure, the valve core 2-4 stays to the upper position in the first valve seat hole 2-6, the sealing ring 2-8 arranged below the valve core 2-4 cuts off the communication between the air channel 2-5 and the gas in the water tank 1-1, meanwhile, the valve top end 2-7 of the valve core 2-4 is inserted into the blocking hole 3-3 at the bottom of the coffee container 3, so as to prevent the heating container 1 from rotating and separating from the bottom of the coffee container 3, thereby preventing the high-temperature liquid and gas in the water tank 1-1 from generating scalding damage; the heating body 1-2 is continuously heated, the gas pressure above the liquid is continuously increased due to the large-scale gasification of the high-temperature liquid, the high-pressure gas extrudes the liquid downwards, the high-temperature liquid enters the powder bin 2-3 through the water inlet channel 2-9 below the powder bearing device 2, and the high-temperature liquid is mixed with the coffee powder to extract the coffee liquid. After coffee extraction is finished, the heating body 1-2 stops heating, but high-temperature and high-pressure gas still remains in the water tank 1-1 at the moment, the valve top end 2-7 of the valve core 2-4 is inserted into the blocking hole 3-3, the heating container 1 cannot be separated from the coffee container 3, only when the temperature is reduced and the air pressure is reduced to a safe range, the valve core 2-4 falls back to a lower position, and when the valve top end 2-7 is separated from the blocking hole 3-3, the heating container 1 can be separated from the coffee container 3, so that safety is ensured.
In the process of normally extracting coffee from the mocha cup, the pressure release valve structure 2-2 is in a closed state, and gas generated by the gasification of the liquid in the water tank 1-1 cannot be discharged to a pressure release hole 3-4 at the bottom of the upper coffee container 3 through the pressure release valve; in the coffee extraction process, the water inlet channel 2-9 is accidentally blocked, continuously heated liquid cannot enter the powder bin 2-3 through the water inlet channel 2-9, the gas pressure in the water tank 1-1 can rapidly rise, and when the gas pressure reaches the working threshold of the pressure release valve structure 2-2, the pressure release valve is opened, so that the gas in the water tank 1-1 can pass through the pressure release valve structure 2-2, the pressure release hole 3-4, the gas outlet channel 3-6 and the exhaust hole 3-7 and then is discharged to the outside of the mocha cup. Thereby ensuring that the gas pressure in the water tank 1-1 is within a safe range.
Compared with the prior art, the portable card cup that rubs that this embodiment provided, compact structure, portable can not only obviously promote the coffee quality, can obviously reduce the safety risk moreover. The portable friction cup of the embodiment has the advantages that the float valve structure is arranged on the powder bearing device, so that the temperature of water entering the powder bin is increased, and the quality of coffee liquid is obviously improved; meanwhile, when the coffee liquid is just extracted, the heating container is under high pressure, the valve core of the float valve structure is in an upper position to prevent the coffee container from being separated from the heating container in a rotating mode, and only when the temperature in the heating container is lowered and the pressure is low enough, the float valve moves downwards to a lower position, the coffee container can be separated from the heating container, and therefore high-temperature steam is prevented from being splashed and scalded. In addition, through setting the relief valve structure on holding the powder ware, the during operation of relief valve structure, the high temperature steam that releases just can not directly outwards splash, causes bodily injury, and when holding the powder ware and wasing, thereby the reliability and the life of improvement relief valve that can be convenient washing relief valve.
