This application claims priority to Chinese Patent Application 201811517500.7, filed on Dec. 12, 2018. Chinese Patent Application 201811517500.7 is incorporated herein by reference.
The present disclosure relates to the field of bathroom fixtures, and in particular to a water outlet device and a driving mechanism for the water outlet device.
Chinese Patent Application CN102728506A discloses an automatic return switching device comprising a body, an upper cover rotatably coupled to the rear side of the body, a driven disc rotatably coupled between the rear side of the body and the upper cover, a clutch mechanism, and a reset device. The body comprises a water-separating device. The clutch mechanism comprises a bidirectional ratchet and a bidirectional lever that cooperates with the bidirectional ratchet. The bidirectional ratchet is rotatably coupled to the rear side of the body and is connected to the water-separating device such that rotation of the bidirectional ratchet drives the water-separating device to switch. The bidirectional lever and the upper cover are connected to the driven disc to drive the bidirectional lever to move between a forward position, a reverse position, and a disengagement position by the rotation of the upper cover relative to the driven disc. When the bidirectional lever is in the forward position, the upper cover rotates in a forward direction to drive the bidirectional ratchet forward, and the ratchet drives the water-separating device to rotate forward to realize switching. When the bidirectional lever is in the reverse position, the upper cover rotates in a reverse direction to drive the bidirectional ratchet to reverse, and the ratchet drives the water-separating device to rotate in a reverse direction to realize switching. The automatic return switching device can only realize resetting. The forward rotating upper cover drives the water-separating device to rotate forward, and the reverse rotating upper cover drives the water-separating device to rotate in reverse, which makes the switching inconvenient.

A length of the second matching part 321′ (the second matching part 321′ comprises an inner matching area 3211′ for connecting to the outer ring supporting part 3322 and an outer matching area 3212′ for connecting to the inner ring supporting part 3321) extending out from the second sealing part 32′ is longer than that of the first matching part 321 extending out from the first sealing part 32.

The water outlet device of the present embodiment is resettable and enables bidirectionally switch of the operating member 21. The water outlet device has the following advantages: 1. the water outlet device can bidirectionally reset and be bidirectionally switched, which can meet the needs of left-handed and right-handed people at the same time (The water outlet devices on the market can be reset and unidirectionally switched, which does not meet the needs of both left-handed and right-handed people), and the convenience is good; 2. the water outlet device can be switched by one hand; 3. the operating stroke is short and the switching force is light, which can meet the high life test standard (150,000 times); 4. the combination of the water spray patterns is large—the water outlet device can realize any combination of single water spray patterns, mixed water spray patterns and water stoppage; and 5. complete water stoppage can be achieved.
A central angle of the first matching part 321 of the first sealing part 32 and a central angle of the second matching part 321′ of the second sealing part 32′ are not larger than that of the inner ring supporting part 3321.

The water-separating body 12 is disposed with the water-separating hole 42 of the water outlet part 40. The fixing seat 13 is disposed with a matching groove 131 corresponding to the water-separating hole 42. The sealing part 32, 32′ is disposed with a through groove 322 configured to adjust water pressure equilibrium. An upper part of the through groove 322 is disposed with an enlarged hole, and a third spring 323 abutting a bottom of the matching groove 131 of the fixing seat 13 is disposed in the enlarged hole. The sealing part 32, 32′ comprises an outer wall of a cylindrical body, and the matching groove 131 and the water-separating hole 42 fit within a cross section of the cylindrical body. Water shut-off state: the sealing part 32, 32′ is in an engaged state Si =S2 (not labeled in the drawing), and the sealing part 32, 32′ is not subjected water pressure. Therefore, when the waterway under the sealing part 32, 32′ needs to be opened, the sealing part 32, 32′ only needs to overcome a force of the third spring 323 of the sealing part 32, 32′. Water on state: water enters an upper chamber defined by the enlarged hole through the through groove 322 below the sealing part 32, 32′, filling the whole sealing part 32, 32′ with water. Therefore, during the water on state, the sealing part 32, 32′ is not subjected to water pressure. When the supporting part 332 of the switching seat 31 disengages with the sealing part 32, 32′, the sealing part 32, 32′ is reset to the water shut-off state due to the force of the third spring 323. The sealing part 32, 32′ is both in a water pressure equilibrium state when it is in a water on state or in a water shut-off state.

The internal gear part 414 comprises an end plate 4141 sealingly and fixedly connected to a lower circumference of the internal gear 418. The end plate 4141 is disposed with at least one water outlet hole 4142, and the small cover 412 is fixedly disposed to a bottom surface of the internal gear part 414. The small cover 412 is disposed with at least one water outlet 4121 aligning with the at least one water outlet hole 4142. Water flows out of at least one inclined water hole 4111 of the first inclined water body 411 and impacts the eccentric impeller 413 to drive the eccentric impeller 413 to rotate. The eccentric pin 416 rotates around an axis of rotation of the eccentric impeller 413. The eccentric pin 416 drives the external gear 417 to rotate around the axis of rotation of eccentric impeller 413. The external gear 417 drives the protrusions extending through the through holes of the water-separating disc 415 to rotate, thereby driving the water-separating disc 415 to rotate so that the at least one water inlet hole 4151 cyclically aligned with the at least one water outlet hole 4142, causing the group of the water outlet parts to discharge a massage water spray. After deceleration, the external gear 417 drives the water-separating disc 415 to rotate, and the four water inlet holes 4151 disposed on the water-separating disc 415 are intermittently aligned with or blocked with the corresponding inner and outer water outlet holes on the internal gear 418 to charge internal and external intermittent massage water. The few teeth difference transmission realizes a switching of the massage water between the inner ring and outer ring (a height of the inner core is low and a noise is low).
In one embodiment, the water outlet device is a shower head. The body 10 of the shower head also comprises a surface cover 14, a decorative cover 15, a body portion 16, and a second inclined water body 17, which are fixedly disposed under the water-separating body 12. The surface cover 14 is fixedly disposed under the second inclined water body 17, and the decorative cover 15 is fixedly disposed on the surface cover 14. The plurality of water outlet parts 40 are equipped with at least one hydrodynamic core 18, which is engaged with the second inclined water body 17, and the body portion 16 is fixedly connected to the surface cover 14. Preferably, the body portion 16 also comprises a spring seat 161 matching with the first spring 561. The rotating part 221 is rotatably connected to the fixing seat 13. The first spring 561 is connected to the fixing seat 13 and the driven wheel 52, and the stop claw 551 is connected to the fixing seat 13. The switching seat 31 comprises a rotary shaft 311. The switching seat 31 is between the fixing seat 13 and the water-separating body 12 and the rotary shaft 311 extends out over the fixing seat 13 and is fixedly disposed on the driven wheel 52.
It will be apparent to those skilled in the art that various modifications and variation can be made in the present disclosure without departing from the spirit or scope of the invention. Thus, it is intended that the present disclosure cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
