[0020] The technical scheme in the embodiment of the utility model will be described clearly and completely in combination with the drawings of the utility model, and obviously, the described content cannot be totally exemplified all implementation schemes, and the following embodiment is only a part of numerous implementation schemes, but not all the embodiment. Based on the disclosure content of the utility model, all other implementation results obtained by the ordinary skill in the art without making creative labor should fall into the scope of the utility model protection.

[0021] EMBODIMENT

[0022] As shown in Figure 1 , Figure 2 , a drawer for conveniently pouring powder comprises a drawer cup seat 1 and a top cover assembly 2, as shown in Figure 2As shown, the top cover assembly 2 is provided with a water inlet 21 and a sealing washer 22, and the drawer cup seat 1 is provided with a brewing support 3 at the bottom, which is sealingly arranged on the side of the drawer cup seat 1 and can be pushed up to push the coffee powder in the drawer cup seat 1. There are sealing structures between the top cover assembly 2 and the drawer cup seat 1 and between the drawer cup seat 1 and the brewing support 3, which guarantee the airtightness of the extraction chamber and form an extraction environment similar to constant pressure extraction. The sealing washer 22 in the top cover assembly 2 also prevents hot water from leaking from the edge of the top cover assembly 2. When the bottom of the brewing support 3 is pushed up, the coffee powder residue on it will be loosened, and no other tools are needed to facilitate pouring and cleaning.

[0023] As shown in Figure 3 , the side wall of the brewing support 3 is attached to the inner wall of the drawer cup seat 1, and a sealing ring 31 is arranged between the side wall of the brewing support 3 and the inner wall of the drawer cup seat 1. As shown in Figure 3 and Figure 6 , the brewing support 3 also includes a coffee liquid outlet 32, and the brewing support 3 also includes a top rod 33 that protrudes downward from the bottom of the drawer cup seat 1. The sealing ring 31 between the brewing support 3 and the inner wall of the drawer cup seat 1 can prevent coffee liquid from leaking, allowing the extracted coffee liquid to flow out only from the outlet 32. After extraction is completed, the top rod 33 can be pushed upward to move the brewing support 3 upward, thereby loosening the coffee powder residue on it from the inner wall of the drawer cup seat 1, which can be easily poured out and cleaned.

[0024] As shown in Figure 5 , Figure 6 , the bottom of the top rod 33 is threadedly connected to a top cap 34, and a first spring 35 is arranged between the bottom of the drawer cup seat 1 and the top cap 34. The top cap 34 can cooperate with the bottom of the drawer cup seat 1 to limit the first spring 35, thereby serving as a return spring for the top rod 33. That is, after extraction is completed and the top rod 33 is pushed, the brewing support 3 is difficult to fall back to its original position due to the increased friction between the side wall of the brewing support 3 and the inner wall of the drawer cup seat 1 caused by the sealing ring 31, and the elastic potential energy of the compressed first spring 35 can push the top cap 34 to move the top rod 33 downward, thereby causing the entire brewing support 3 to automatically fall back to the bottom of the drawer cup seat 1, facilitating powder loading and extraction for the next time.

[0025] As shown in Figure 3 , a one-way valve 36 is arranged in the outlet 32, which forms a constant pressure inside during extraction. As shown in Figure 6 , the one-way valve 36 includes a cavity in the brewing support 3 that communicates with the space above and below, as well as a plug 361, a second spring 362, and a plug cover 363. The plug 361 and the plug cover 363 each have a shoulder portion that limits the upper end and the lower end of the second spring 362, respectively. The plug 361 is limited by the narrowed outlet 3 at the top of the cavity, and the plug cover 363 is provided with a through hole and is threadedly connected to the brewing support 3. The arrangement of the one-way valve 36 guarantees the pressure in the extraction chamber and forms an extraction environment similar to constant pressure extraction.

[0026] As Figure 3 , Figure 5 and Figure 6 shown, the brewing support 3 is provided with a detachable filter screen 37 above it. The filter screen 37 is used to filter the coffee powder residue, block it from clogging the flow outlet 32 or flowing out of the flow outlet 32 to affect the taste of coffee. The filter screen 37 can be fixed to the top of the brewing support 3 by screws or the like.

[0027] As Figure 4 shown, the top cover assembly 2 includes a top cover shell 23, one end of which is rotatably connected with the drawer cup holder 1, and the other end is provided with a handle 231 to facilitate lifting the relatively sealed top cover assembly 2, and the top cover shell 23 is provided below with an annular groove 232 containing a sealing washer 22, and the top cover assembly 2 further includes a pressing disc 24 fixed to the top cover shell 23 by screws 25, which can limit the sealing washer 22, and the pressing disc 24 has a through hole 241. The structure of the pressing disc 24 and the sealing washer 22 makes the sealing washer 22 more firmly installed under the top cover shell 23, and it will not be deformed and fall off to lose the sealing effect due to frequent opening and closing of the top cover assembly 2.

[0028] As Figure 6 shown, the inner ring of the sealing washer 22 is provided with a stepped surface 221 and a downwardly protruding extension 222 in the middle, and the outer ring of the pressing disc 24 is upwardly protruded to form a shoulder 242, which abuts against the stepped surface 221. The side surface of the shoulder 242 supports the extension 222 of the sealing washer 22, so that the extension 222 is pressed and sealed against the inner wall of the drawer cup holder 1.

[0029] As Figure 4 shown, a plurality of through holes 241 are arranged on the pressing disc 24, and the through holes 241 are larger at the top and smaller at the bottom. The multiple rows of through holes 241 are evenly distributed on the pressing disc 24, which can disperse the water flow and make the hot water evenly sprinkle on the coffee powder to ensure sufficient extraction.

[0030] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and equivalent changes made to the structure, shape and principle within the scope of knowledge possessed by those skilled in the art fall within the protection scope of the utility model.
