In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting and the like should be interpreted broadly, and the skilled in the art can determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0025] As shown in Figures 1 to 6 The first aspect of the present application provides a powder brewing assembly, which comprises a brewing seat 100, a cover 200, a supporting tray 300 and a pressure bearing 400. The brewing seat 100 is internally provided with a brewing cavity 105, and the brewing seat 100 is provided below with a liquid outlet 102. The cover 200 is rotatably connected with the brewing seat 100, and when the cover 200 is buckled with the brewing seat 100, it forms a closed brewing cavity 105, and after the cover 200 is opened, the supporting tray 300 or the powder bag can be placed. The cover 200 is provided with a water inlet hole, which can be connected with the water outlet pipe of the water tank.

[0026] The supporting tray 300 is detachably arranged on the brewing cavity 105, and the supporting tray 300 is internally provided with a liquid guide hole 301, which is in communication with the liquid outlet 102, and the dissolved coffee liquid flows out along the liquid guide hole 301. The pressure bearing 400 is arranged in the cover 200, and the pressure bearing 400 is provided with a plurality of protruding parts 401, each of which is provided with a liquid injection port 402 for communication with the water inlet hole.

[0027] By providing a spray nozzle 402, the water pressure is increased by using the spray nozzle 402 on the pressure bearing component 400, so that the water can fully contact the coffee powder in a spray form, accelerate the dissolution, improve the dissolution efficiency of the coffee powder, greatly reduce the coffee powder residue in the coffee powder bag, and improve the dissolution rate of the coffee powder in the entire coffee powder bag.

[0028] Optionally, there are five protrusions 401, which are evenly distributed along the center of the pressure-bearing member 400. After passing through the pressure-bearing member 400, water is sprayed onto the coffee powder through the spray nozzles 402 on the five evenly distributed protrusions 401 to evenly rinse and dissolve the coffee powder.

[0029] Considering that hot water or coffee liquid may leak from the edge gaps of the lid 200 and brewing base 100 during use, in some embodiments, a sealing ring 500 is provided on the outside of the pressure member 400. The sealing ring 500 is annular and may be made of elastic material, and the sealing ring 500 corresponds to the edge of the support tray 300.

[0030] For example, the sealing ring 500 is a rubber sealing ring 500. When the lid 200 is fastened onto the brewing base 100, the sealing ring 500 on the outer side of the pressure-bearing member 400 contacts and is pressed against the edge of the support tray 300 as the lid 200 descends. Utilizing the elastic deformation of the sealing ring 500, under the pressure generated when the lid 200 and the brewing base 100 are fastened, the sealing ring 500 fits tightly against the edge of the support tray 300, preventing liquid from flowing out from the edge gaps. Therefore, when the lid 200 and the brewing base 100 are fastened, the sealing ring 500 and the support tray 300 are pressed together, ensuring a tight seal and preventing hot water or coffee liquid from seeping and leaking along the connection between the lid 200 and the brewing base 100.

[0031] In some embodiments, multiple liquid guiding holes 301 are provided, and the multiple liquid guiding holes 301 are spaced apart along the circumferential direction of the support tray 300. After the coffee powder is dissolved to form coffee liquid, it flows into the bottom of the brewing base 100 through the multiple spaced liquid guiding holes 301, and then flows out through the liquid outlet 102.

[0032] In some embodiments, a plurality of upwardly protruding ribs 302 are evenly distributed within the tray 300, and the plurality of ribs 302 are arranged around the liquid guiding hole 301. By providing the ribs 302, the liquid guiding hole 301 is prevented from being blocked, ensuring that the dissolved coffee liquid can flow smoothly through the liquid guiding hole 301 to the liquid outlet 102 below the brewing base 100, ensuring smooth flow of coffee liquid throughout the brewing process and improving brewing efficiency.

[0033] In some embodiments, a limiting step 103 is arranged in the brewing seat 100, and the outer edge of the supporting tray 300 is matched with the limiting step 103. When installed, the outer edge of the supporting tray 300 is aligned with the limiting step 103, so as to fix the supporting tray 300 on the limiting step 103, thereby ensuring the accurate position of the supporting tray 300 and facilitating the installation and disassembly. Meanwhile, due to the limitation of the limiting step 103, the supporting tray 300 cannot be displaced or shaken, thereby ensuring the stability of the brewing process.

[0034] In some embodiments, a flow guide valve 600 is arranged in the brewing seat 100, and the flow guide valve 600 comprises a valve cover 601 and a valve rod 602. The lower end of the valve rod 602 is connected with the first liquid outlet 102, the upper end of the valve rod 602 is connected with the valve cover 601, the valve cover 601 corresponds to the liquid guide hole 301, and the side wall of the valve rod 602 is provided with a flow guide hole 603 which is communicated with the liquid outlet 102.

[0035] In this way, after the coffee liquid flows out of the liquid guide hole 301, it is not directly flowed from the inside of the brewing cavity 105 to the liquid outlet 102. Instead, when falling, the liquid is contacted with the valve cover 601 or the inner wall of the bottom of the brewing seat 100. Part of the falling liquid is buffered by the valve cover 601, and the liquid flows along the bottom of the brewing seat, and then flows into the flow guide hole 603 in the flow guide valve 600, and then flows along the inside of the valve rod 602, and finally flows along the liquid outlet 102. Therefore, the phenomenon of deflection of the coffee liquid during the liquid outlet process can be effectively prevented, and the stability and smoothness of the liquid outlet can be ensured.

[0036] In some embodiments, the cover 200 is further provided with a handle 201. The handle 201 is rotated and pressed to buckle the cover 200 on the brewing seat 100. When the cover 200 needs to be buckled, the handle 201 is held and rotated and pressed downward, so that the cover 200 is buckled with the brewing seat 100. When the cover 200 needs to be opened, the handle 201 is held and rotated and lifted upward, so that the cover 200 can be opened. In this way, the opening and closing of the cover 200 can be realized by rotating and moving up and down, which is simple to operate. In addition, it can also be used to lift the entire powder bag brewing assembly.

[0037] Further, the brewing seat 100 is provided with outwardly extending pin shafts 104 which are symmetrically arranged on both sides of the brewing seat 100. The handle 201 is correspondingly provided with clamping hooks 202 on both sides, and the clamping hooks 202 are used to connect and clamp with the pin shafts 104. Then the handle 201 is pulled back to the initial position, and the clamping hooks 202 of the handle 201 are just matched with the clamping pins. Therefore, the connection between the cover 200 and the brewing seat 100 is more stable through the connection and clamping of the clamping hooks 202 and the pin shafts 104.

[0038] The second aspect of the present application provides a coffee machine comprising the capsule brewing assembly as described above. After the coffee machine is started, water enters the cover 200 of the capsule brewing assembly through the water inlet hole, is sprayed onto the coffee powder in the supporting tray 300 through the pressure bearing piece 400, and is fully mixed and dissolved with the coffee powder to form coffee liquid, which flows out through the flow guide hole 603 and the liquid outlet 102 to realize the brewing and output of coffee.
