The push rod mechanism 2 includes a push rod 21 and a cover plate 22 arranged on the top of the push rod 21. The push rod 21 drives the cover plate 22 to reciprocate in the accommodating cavity 11, and the accommodating cavity 11 and the cover plate 22 are enclosed to form a cavity for placing coffee powder. In addition, a water inlet channel for hot water to enter is provided in the cover plate 22, and the water inlet channel is connected to the cavity.

[0037] Therefore, when the push rod 21 drives the cover plate 22 to move to the bottom of the accommodating chamber 11, the coffee machine is in standby mode. When coffee needs to be brewed, the coffee powder is first allowed to enter the chamber and be compacted, and then hot water enters the chamber through the water inlet channel to brew the coffee powder. The coffee liquid formed after brewing is discharged through the water outlet pipe (not shown in the figure), and finally the push rod 21 drives the cover plate 22 to move up to the top of the accommodating chamber 11 to push out the coffee powder cake to achieve residue discharge.

[0038] The present application further includes a filter screen 23 disposed on the top of the cover plate 22, and the filter screen 23 is connected to the cavity and the water inlet channel respectively. The filter screen 23 is provided with a plurality of filter holes, which can block the coffee powder while allowing hot water to pass smoothly. Therefore, by providing the filter screen 23, the phenomenon of coffee powder back-sucking during the brewing process can be avoided, thereby ensuring the quality of coffee brewing, and preventing the coffee powder from flowing into other parts and causing cleaning difficulties. At the same time, the filter screen 23 can also slow down the flow rate of hot water entering the cavity, prolong the time that hot water stays in the coffee powder layer, so that the complete coffee substance can be extracted, thereby improving the mellowness of the coffee liquid.

[0039] For details, see Figure 2-5 The powder bin assembly also includes a water inlet pipe 24. The cover plate 22 is provided with a through-mounting groove 2241.
