During the downward movement of the pressing member 20, the third inclined surface 221 gradually contacts the fourth inclined surface 35. Under the action of the third inclined surface 221, the fourth inclined surface 35 and the third spring 223, the pressing member 20 moves away from the protrusion 11, causing the fork 21 to disengage from the protrusion 11, thereby relieving the pressure applied to the protrusion 11. At the same time, under the action of the first spring 15, the vibrating plate 12 quickly returns to its original position and impacts the powder outlet pipe. On 30, the powder outlet pipe 30 vibrates to shake off the residual coffee powder; the key cap 23 is released, causing the second spring 29 to drive the key cap 23 and the pressing member 20 to return to their original position. During the upward return process, the upper surface of the fork 21 abuts against the lower surface of the protrusion 11, causing the first inclined surface 111 and the second inclined surface 211 to contact. Under the action of the third spring 223, the first inclined surface 111 and the second inclined surface 211 cooperate to push the pressing member 20 away from the protrusion 11 until the upper surface of the fork 21 no longer contacts the lower surface of the protrusion 11, so that the fork 21 of the pressing member 20 returns to above the protrusion 11 under the action of the second spring 29 and the third spring 223.

[0047] This invention utilizes the pressing of the keycap 23 to cause the pressing member 20 to press against the protrusion 11, thereby moving the vibrating plate 12 downwards. During this process, the third inclined surface 221, in conjunction with the fourth inclined surface 35, releases the pressing member 20 from pressing against the protrusion 11. Under the action of the first spring 15, the vibrating plate 12 quickly resets and vibrates, dislodging residual coffee powder. Under the action of the second spring 29, the keycap 23 resets, and simultaneously, the pressing member 20 is reset under the action of the third spring 223, the first inclined surface 111, and the second inclined surface 211, facilitating further cleaning. The cleaning effect is good, and the pressing method makes operation simple and convenient.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
