Through the above structural arrangement, the flushing water first enters the water inlet cavity from the water inlet 311, and then uniformly flows out from the plurality of water outlet holes 321, and a small amount of water can also achieve good cleaning effect.

[0032] As shown in FIGS. 4-7, the upper cover 31 is a horn shape with a small upper part and a large lower part, the lower cover 32 is arranged as a structure with a middle part protruding upward, and the lower cover 32 is circumferentially distributed with a plurality of water outlet holes 321. Through the above structural arrangement, the flushing water can quickly reach the water outlet holes 321 after entering the water inlet cavity from the water inlet 311, which correspondingly reduces the cleaning time and provides a better experience for the user.

[0033] Further, the bottom of the lower cover 32 is arranged as a structure with a middle part concave inward. Through the above structural arrangement, when flushing, the lower cover 32 with the concave bottom is more conducive to the downward flow of the flushing water, which accelerates the flushing of the powder inlet 112, and after the flushing is completed, the bottom of the lower cover 32 is also not easy to accumulate water.

[0034] Further, the plurality of water outlet holes 321 are arranged in a circle. Through the above structural arrangement, the four sides of the powder inlet 112 can be fully cleaned.

[0035] Further, the bottom of the lower cover 32 is circumferentially provided with a plurality of drainage grooves 322 corresponding to the water outlet holes 321. Through the above structural arrangement, the flushing water can be drained to the edge of the powder inlet 112, which is conducive to the flushing of the powder inlet 112 and can effectively prevent the flushing water from seeping out.

[0036] As shown in FIG. 1, the water inlet pipe 4 is connected with a water pump 5 at the end away from the flushing head 3. Through the above structural arrangement, the flushing power of the flushing water can be enhanced.

[0037] As shown in FIG. 8, the lower part of the brewing device 1 is provided with a water receiving box 6 for receiving flushing sewage. Through the above structural arrangement, the water receiving box 6 is also a coffee residue receiving box of the coffee machine, and the flushing can be completed without too many changes in the structure of the coffee machine.

[0038] As shown in Figure 8, the brewing cavity 11 is provided with a pusher 7 away from the opening 111, the free end 71 of the pusher is provided with a brewing liquid outlet hole, and the end of the brewing seat 2 opposite to the brewing device 1 is provided with a hot water inlet hole. This part belongs to the prior art, the pusher 7 is mainly used for compacting and compacting coffee powder, and also for pushing out coffee residue after coffee preparation. After the utility model adds the flushing head 3, the pusher 7 can also realize the water scraping function in the brewing cavity 11 while pushing the coffee residue, so that the brewing cavity 11 is cleaner.

[0039] The above is only the preferred embodiment of the utility model, so equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application range are included in the utility model patent application range.
