As shown in fig. 17, the guide slot 630 guides the positioning protrusion 620 to move, so as to prevent the positioning protrusion 620 from deviating from the positioning groove 610 when the second funnel 420 moves, and ensure that the positioning protrusion 620 can fall into the positioning groove 610.

Optionally, the depth or width of the positioning groove 610 needs to be greater than the width or depth of the guide groove 630, so as to ensure that the positioning salient point 620 can be clamped into the positioning groove 610 after moving on the guide groove 630; and, the depth or width of the positioning groove 610 is different from the width or depth of the guide groove 630; then, after the positioning protruding point 620 is clamped into the positioning groove 610 at a higher position, the connecting surface between the positioning groove 610 and the guide groove 630 forms a support for the positioning protruding point 620, so that the positioning protruding point 620 cannot enter the guide groove 630 from the positioning groove 610, and the resistance of the connecting surface must be overcome under an external force, so that the positioning protruding point 620 enters the guide groove 630 after being deformed.

Furthermore, the second funnel 420 is provided with an elastic plate 421 at the upper edge, the positioning protrusions 620 are provided on the elastic plate 421, and only one side of the elastic plate 421 is connected to the second funnel 420, so that the elastic plate 421 can move outward relative to the second funnel 420 under external force; that is, in the process of moving the second funnel 420, the positioning protrusions 620 are pressed against the guide grooves 630, so that the elastic plate 421 has a certain outward moving force, and after the positioning protrusions 620 correspond to the positioning grooves 610, the elastic plate 421 is restored, so that the positioning protrusions 620 are engaged with the positioning grooves 610.

Further, the positioning protrusions 620 are symmetrically disposed on the second funnel 420 in two sets, so that the positioning grooves 610 and the guide slots 630 are also symmetrically disposed on the first funnel 410.

Furthermore, in the positioning structure 600, the first funnel 410 is provided with a positioning groove 610 and a guiding groove 630, and the second funnel 420 is provided with a positioning protrusion 620; alternatively, the second funnel 420 may be provided with a positioning groove and a guide groove, and the first funnel 410 may be provided with a positioning protrusion.

Further, the lower parts of the first funnel 410 and the second funnel 420 are frustum-shaped, and the inner bottom walls of the first leakage groove 410 and the second funnel 420 are both obliquely arranged and are inclined towards the center of the water outlet hole 401, so that the medium can be gathered towards the central hole 401 and flow out through the central hole 401.

Further, the number of the second funnels 420 may be set to 2, that is, the second funnel a and the second funnel B, so that three-stage stretching may be achieved. The second funnel A is connected with the first leakage ditch 410, the second funnel B is connected with the second funnel A, the positioning structure 600 is also arranged between the second funnel B and the second funnel A, and the second funnel B and the second funnel A move up and down in the same mode to realize three-stage stretching.

In the third embodiment, as shown in fig. 18, since the second funnel 420 is sleeved outside the first funnel 410, some of the medium remains between the outer wall of the first funnel 410 and the inner wall of the second funnel 420 during the process of delivering the medium, which is easy to accumulate dirt and bacteria, so that it is necessary to design the second funnel 420 and the first funnel 410 in a detachable manner, so as to facilitate cleaning after removing the two.

Then, the lower end of the guide slot 630 is an open end, and when the positioning protrusion 620 on the second funnel 420 moves along the guide slot 630 and moves to the lower end of the guide slot 630, it can directly slide out of the guide slot 630, thereby removing the second funnel 420 from the first funnel 410.

In this structure, the positioning groove 610 is disposed beside the guiding groove 630 and connected to the guiding groove 630, and when the second hopper 420 moves to a proper position, the second hopper 420 rotates counterclockwise, so that the positioning protrusion 620 on the second hopper 420 leaves the guiding groove 630 and is screwed into the positioning groove 610 for positioning; similarly, when the height of the second funnel 420 needs to be adjusted, the second funnel 420 is rotated clockwise, so that the positioning protrusions 620 leave the positioning grooves 610 and enter the guide grooves 630, and after the positioning protrusions move to appropriate positions along the guide grooves 630, the second funnel 420 is rotated counterclockwise again for positioning.
