[0032] The powder stirrer of the present application has many advantages in actual use. When in use, the support body 1 is in contact with the powder receiving cup, so that the support body 1 with an open accommodating space is covered on the bowl of the powder receiving cup, and the stirring part of the stirring structure extends into the powder receiving cup. By adjusting the reciprocating telescopic change of the telescopic member 2, the driving member 11 drives the transmission rod 7 to rotate back and forth in the first direction and the second direction, and then drives the stirring structure to rotate, so as to achieve uniform stirring of the coffee powder in the powder receiving cup. In the present application, the reciprocating rubbing rotation method of the traditional stirrer is replaced by pressing the telescopic member 2, which is simpler to operate and easier to adjust. At the same time, through the design of the support body 1, the relative positioning of the stirring structure and the powder receiving cup is achieved, so that the rotation stability of the stirring structure is better.

[0033] It is understandable that the support body 1 of the open receiving space may be a concave structure, a cylindrical structure, or a Figure 1 The frame structure shown.

[0034] As a preferred embodiment, the telescopic member 2 may include a first ring member 201 and a second ring member 202, one end of the first ring member 201 is connected to the support body 1, and the other end is sleeved and connected to the second ring member 202, and is telescopically matched with the second ring member 202; Figure 1 , Figure 2 It is illustrated that the other end of the first ring member 201 is inserted into the second ring member 202. In actual implementation, it can also be inserted into the second ring member 202. The first ring member 201 is sleeved on the transmission rod 7, and the driving member 11 is arranged inside the second ring member 202.

[0035] In the above embodiment, the transmission rod 7 is located inside the first ring member 201, realizing a hidden design of the transmission rod 7. In this way, the rotation of the transmission member is performed inside the first ring member 201, avoiding the problem that the exposed design easily causes safety accidents. At the same time, space is saved, making the molding and pressing assembly smaller and more compact, and having strong practicality.

[0036] Please refer to Figure 2 and Figure 7 As a preferred embodiment, the transmission rod 7 is a spiral rod; wherein the driving member 11 is an annular member, one end of the driving member 11 is connected to the second annular member 202, and the other end is sleeved on the transmission rod 7, and a spiral groove adapted to the transmission rod 7 is provided inside the driving member 11.

[0037] In the above embodiment, when the second annular member 202 is telescopically transformed relative to the first annular member 201, the spiral groove of the driving member 11 matches the spiral rod, thereby driving the spiral rod to rotate back and forth, thereby realizing the back and forth driving of the stirring structure to achieve the purpose of stirring the powder.

[0038] Further, a pressing head 203 is threadedly matched at one end of the second annular member 202 away from the first annular member 201. A threaded groove is arranged at one end of the driving member 11 away from the pressing head 203, and the driving member 11 is threadedly matched with the pressing head 203. And the end of the transmission rod 7 extending into the interior of the driving member 11 is threadedly matched with an anti-detachment nut, which can be rotated and slid in the driving member 11, and cannot be taken out from the rotating groove, but can be taken out from the port of the driving member 11 connected to the pressing head 203, so as to realize the detachable matching of the second annular member 202 and the transmission rod 7.

At this time, the stirring part of the stirring structure extends into the powder receiving bowl, and the powder receiving bowl is located in the inner space of the third ring member 4, and the powder stirring operation can be performed. In actual use, the rotation of the fifth ring member 13 relative to the third ring member 4 can be adjusted to achieve the spacing adjustment between the fourth ring member 5 (when it is at the bottom position of the third ring member 4) and the annular stopper 14, that is, the depth of the stirring part of the stirring structure in the powder receiving bowl can be adjusted. Such a design has a wider range of use and greater flexibility. Optionally, an anti-slip pattern is provided on the outer side of the fifth ring member 13 to facilitate the adjustment of the toggle of the fifth ring member 13. In addition, the wing plate 102 and the third ring member 4 are detachably connected by bolts.

[0048] Optionally, a limiting protrusion 16 is provided at the lower part of the inner side wall of the third ring member 4 to limit the fifth ring member 13 from sliding out of the third ring member 4.
