The detailed working process of the portable mocha cup is as follows:
when the heating body 1-2 of the heating container 1 starts to heat, the temperature of the liquid in the water tank 1-1 is low, the expansion and gasification of the liquid are small, a small amount of gas is discharged upwards through the air channel 2-5 of the valve core 2-4, and is discharged to the outside of the Mocha cup after passing through the blocking hole 3-3, the air passing channel 3-6 and the exhaust hole 3-7; the valve core 2-4 stays at a lower position in the first valve seat hole 2-6 of the powder bearing device 2 due to the action of gravity; 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 cannot 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 air channel 2-5 from being communicated with the gas in the water tank 1-1, and 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 to block the heating container 1 from rotating and separating from the bottom of the coffee container 3, so that the damage of scalding caused by high-temperature liquid and gas in the water tank 1-1 is prevented; the heating body 1-2 is continuously heated, the high-temperature liquid is largely gasified to cause the gas pressure above the liquid to continuously rise, the high-pressure gas extrudes the liquid downwards, so that the high-temperature liquid enters the powder bin 2-3 through the water inlet channel 2-9 below the powder bearing device 2, is mixed with the coffee powder, and extracts the coffee liquid. After the coffee extraction is completed, the heating body 1-2 stops heating, but high-temperature and high-pressure gas still remains in the water tank 1-1, 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, and only when the temperature is reduced and the air pressure is reduced within a safe range, the valve core 2-4 falls back to a lower position, and the valve top end 2-7 leaves the blocking hole 3-3, the heating container 1 can be separated from the coffee container 3, so that the safety is ensured.
In the normal coffee extraction process of the mocha cup, the pressure release valve structure 2-2 is in a closed state, and gas generated by gasifying liquid in the water tank 1-1 cannot be discharged to the pressure release hole 3-4 at the bottom of the upper coffee container 3 through the pressure release valve; when the water inlet channel 2-9 is accidentally blocked in the coffee extraction process, the 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, when the gas pressure reaches the working threshold value of the pressure relief valve structure 2-2, the pressure relief valve is opened, and the gas in the water tank 1-1 can be discharged to the outside of the Mocha cup after passing through the pressure relief valve structure 2-2, the pressure relief hole 3-4, the gas outlet channel 3-6 and the exhaust hole 3-7. Thereby ensuring that the gas pressure in the water tank 1-1 is within a safe range.
Compared with the prior art, the portable mocha cup provided by the embodiment has the advantages of compact structure and portability, and can not only obviously improve the quality of coffee liquid, but also obviously reduce the safety risk. The portable friction card cup of the embodiment improves the temperature when water starts to enter the powder bin by arranging the float valve structure on the powder bearing device, and obviously improves the quality of coffee liquid; and when the coffee liquid is just extracted, the heating container is at high pressure, the valve core of the float valve structure is at an upper position to prevent the coffee container from rotating and separating from the heating container, and the float valve moves downwards to a lower position only when the temperature in the heating container is reduced and the pressure is low enough, so that the coffee container can be separated from the heating container, and the high-temperature steam is prevented from splashing and scalding. In addition, through setting up the relief valve structure on carrying the powder ware, the relief valve structure during operation, the high temperature steam that releases just can not directly outwards splash, causes personal injury to and when carrying the powder ware to wash, thereby the reliability and the life of improvement relief valve that can be convenient wash.
The foregoing embodiments have been provided for the purpose of illustrating the general principles of the present application, and are not meant to limit the scope of the invention, but to limit the scope of the invention.
