The plunger 55 is also provided with a plunger 12 which can be pushed down. The ejector pin 55 can be pressed downward by downward movement of the end of the pressing rod 12 inserted into the liquid inlet 51. When the filter tank 11 is filled with ground coffee powder, the ejector block 56 moves downwards along with the ejector rod 55 to compact the coffee powder; when the boiled water is poured in again, the boiled water can form slower permeation filtration at the lower part of the filter tank 6, so that the dissolved matters in the coffee powder are dissolved into the liquid and finally flow into the lower cup body 2.
In addition, as shown in fig. 1, a pressure cover 13 is designed at the upper part of the upper cup body 1, the pressure cover 13 protrudes upwards, and when the liquid storage tank 11 of the upper cup body 1 is filled with liquid, a containing cavity is formed between the pressure cover 13 and the liquid; the pressure cover 13 is provided with a gas valve 14 for one-way inflation into the accommodating cavity, and the gas valve 14 is provided with a pressure bag 15. The air valve 14 can make the pressure bag 15 to the unidirectional inflation of pressure lid 13 lower cavity, so people just can be manually through holding pressure bag 15 to make the inside boiling water of reservoir 11 have pressure, not only make the boiled water outflow of play liquid hole 52 more quick, simultaneously can be smoothly with the more thorough extrusion of boiling water in the coffee powder in the filter vat is to lower cup 2 in the lower part, thereby realize similar original steam extraction technology in the coffee extraction, make this coffee cup make the technology of coffee beverage more, thereby give more quotations and choices of people.
In a specific design, as shown in fig. 1, one end of the pressure lever 12 is hinged to a middle position at the upper part of the pressure cover 13, a horizontal direction accommodating groove 131 is designed on the pressure cover 13, and when not in use, the pressure lever 12 is obliquely placed into the accommodating groove 131. When the pressure cover 13 is required to be used, the pressure cover 13 is unscrewed, then the pressure rod 12 on the pressure cover 13 is broken off, so that the pressure rod 12 is perpendicular to the pressure cover 13, then the pressure cover 13 is inverted, the pressure rod 12 is inserted into the liquid inlet 51 at the upper part of the center shaft 5, thus the pressure rod 12 can be operated through the pressure cover 13, the end part of the pressure rod 12 is more conveniently inserted into the liquid inlet 51, the push rod 55 is conveniently pushed downwards, and the pressure cover is more convenient to use.
As shown in fig. 1 and 2, the pressure lever 12 is in a hexagonal prism shape, a hole groove structure corresponding to the pressure lever 12 is processed in the liquid inlet 51 at the upper part of the center shaft 5, and the pressure lever 12 can be limited to extend into the liquid inlet 51; at this time, the pressure cover 13 can control the pressure rod 12 to press the ejector rod 55 up and down, and meanwhile, the pressure cover 13 can be rotated to drive the center shaft 5 to rotate, so that manual work of the grinding component in the grinding module 4 is synchronously controlled, and manual grinding is realized.
