On the other side, described first rotates adjusting portion 31 comprises a spline rod 311, and the periphery of its one end has the first external splines 312, and the other end forms coaxial rotation with described second external splines 301 and coordinates; Therefore, when rotating described first external splines 312, described spline rod 311 and center-pole 30 coaxial rotation.
In order to realize the effect of Flow-rate adjustment: described flow control division 33 comprises dwang 331 and first guide rod 332 of coaxial setting; One end of described dwang 331 have to match with described outer-hexagonal 302 in hexagonal 333, therefore, when center-pole 30 rotates, described dwang 331 also coaxial rotation.The other end of described dwang 331 and one end of the first guide rod 332 are cooperatively interacted by the first transmission thread 334.Therefore, when dwang 331 rotates, described first guide rod 332 axially moves up and down.
The mouth of a river 13 is blended described in the ending vertical of described first guide rod 332 is communicated to; The described mouth of a river 13 that blends has the first sealing gasket 131 matched with the end of described first guide rod 332, when the end movement of described first guide rod 332 is to during with the first sealing gasket 131 contact, described in blend the mouth of a river 13 and be fully closed.
By setting as above, when just having reached first external splines 312 on rotation spline rod 311 top, center-pole 30, dwang 331 are also along with spline rod 311 coaxial rotation, and the first guide rod 332 axially moves up and down, thus make the first guide rod 332 ending vertical be communicated to the portion stretches or shortening that blend the mouth of a river 13, therefore, the water-outlet area blending the mouth of a river just changes along with the rotation of spline rod 311, and water flow also just changes thereupon.
In order to realize the effect of the interlock of the second rotation adjusting portion 32 and regulating element, the concrete structure of the present embodiment is as described below:
Described second rotate adjusting portion 32 comprise one with the coaxial adjustable lever 321 that arranges of center-pole 30 and depression bar 322; One end of described adjustable lever 321 and depression bar 322 is cooperatively interacted by the second transmission thread 323, and therefore, when described adjustable lever 321 rotates, described depression bar 322 axially moves up and down.
The other end of described depression bar 322 and described center-pole 30 contact, thus make depression bar 322 and center-pole 30 in the axial direction interlock arrange.Reach the object that the interlock of adjusting portion 32 and regulating element is rotated in rotation second.
In order to realize thermoregulator effect: described temperature regulation section 34 comprises the second guide rod 341 and plunger 342; Described second guide rod 341 is arranged between described thermosensitive element 2 and center-pole 30, and described second guide rod 341 and thermosensitive element 2 and center-pole 30 are distinguished interlock in the axial direction and arranged.Concrete structure is: described center-pole 30 has a holding cavity 303, one end of described second guide rod 341 is inserted in described holding cavity 303 and is realized and center-pole 30 interlock, the other end is exposed to the outside of described center-pole 30 and has the second outer-hexagonal 347, one end of described thermosensitive element 2 to be inserted in the second guide rod 341 by a gland 23 and a nut 24 and fastening, thus realizes interlock.
