Referring to fig. 1 to 15, a water outlet device is disclosed, which can be installed on a kitchen faucet for use, and comprises a water passing member 10 and a water outlet member 20, wherein the water passing member 10 is provided with a plurality of jet holes 11, the water outlet member 20 is provided with different water flow channels, the water passing member 10 is rotationally connected with the water outlet member 20, the jet holes 11 are communicated with the different water flow channels through the relative rotation of the water passing member 10 and the water outlet member 20, the water passing member 10 is provided with a cavity 12, and the water inlet end of the cavity 12 is provided with an opening; the water outlet piece 20 is provided with a first abutting part 21; the sliding block 31, the rotating block 32 and the elastic element 33 are further included, the rotating block 32 is provided with a second abutting portion 321, the sliding block 31 and the rotating block 32 can rotate relatively, and the elastic element 33 is used for restraining the sliding block 31 and the rotating block 32 from rotating relatively; the sliding block 31 and the rotating block 32 are sequentially arranged in the cavity 12 of the water passing member 10 along the water outlet direction, the sliding block 31 can move along the axial direction of the cavity 12, the rotating block 32 can rotate along the circumferential direction of the cavity 12, and the second abutting part 321 of the rotating block 32 can abut against or be separated from the first abutting part 21 of the water outlet member 20 along the circumferential direction of the cavity. The constraint of the elastic element 33 on the slider 31 and the rotation block 32 is understood to mean that the elastic element limits the relative rotation of the slider 31 and the rotation block 32 in the circumferential direction.

When the tap is not in water passing, the jet hole 11 is aligned with a water flow passage, the second abutting part 322 of the rotating block 32 is sufficiently close to or in an abutting state with the first abutting part 21 of the water outlet piece 20, and the sliding block 31 and the rotating block 32 are in a stable relative position by the constraint of the elastic element 33; when the faucet is filled with water, the sliding block 31 is under the action of the water pressure, and when the water pressure is greater than the rotating force restrained by the elastic element 33, the sliding block 31 moves in the cavity 12 along the axial direction towards the water outlet direction, so as to drive the rotating block 32 rotationally connected with the sliding block 31 to rotate along the circumferential direction (which can be defined as the rotating block 32 rotating towards the first direction at the moment), the second abutting part 321 of the rotating block 32 is separated from the first abutting part 21 of the water outlet piece 20 by the rotation, the elastic element 33 is in a state of accumulating the rebound force, and meanwhile, water is ejected to the water flow channel through the jet hole 11 and leaves the water outlet device from the water flow channel to generate first water spray; during water passing, the user can rotate the water outlet member 20 (the rotation direction is the same as the first direction) to allow the other water flow passage to abut against the water inlet hole 11, so that water flows out of the water outlet device from the water flow passage to generate second water spray, and the rotation of the water outlet member 20 allows the first abutting part 21 of the water outlet member 20 to rotate towards the second abutting part 321 of the rotating block 32, so that the water outlet member 20 is sufficiently close to or in an abutting state, and the elastic element 33 is kept in a state of accumulating the rebound force due to the continuous action of the water pressure; when the water supply of the faucet is stopped in a state where the second water spray is generated, the elastic member 33 releases the elastic force and returns to the original state after the restriction of the hydraulic pressure is lost, and during the return of the elastic member 33 to the original state, the rotation block 32 rotates in the circumferential direction (at this time, the rotation block 32 rotates in the second direction opposite to the first direction) by the elastic force, so that the second abutting portion 321 of the rotation block 32 abuts against and pushes the first abutting portion 21 to rotate (the rotation direction is the same as the second direction), until the rotation block 32 returns to the original position, and the water outlet member 20 also returns to the original position, and the rotation of the rotation block 32 drives the slider 31 rotatably connected thereto to return to the original position.

It will be appreciated that in a situation where water is not flowing, even if the second abutting portion 321 and the first abutting portion 21 are in the initial position, they are sufficiently close to each other or in contact, the water outlet member 20 can be rotated under the action of an external force (the water outlet member 20 is not locked in all embodiments), but in this state, the rotation of the water outlet member 20 needs to overcome the constraint force of the elastic member 33, i.e. the external force needs to apply a force to the water outlet member 20 to make the first abutting portion 21 push the second abutting portion 321 to drive the rotating block 32 to rotate against the constraint force of the elastic member 33, and after rotating to the final position, the external force must be maintained to keep the water outlet member 20 in the switched position, and once the external force is removed, the elastic member 33 rotates the rotating block 32 back to the original position, thereby driving the water outlet member 20 to return to the initial position. The elastic element 33 in this embodiment may be a compression spring or a torsion spring.

In order to realize that the sliding block 31 axially moves in the cavity 12 and the rotating block 32 can rotate in the cavity 12 along the circumferential direction, the sliding block 31 and the rotating block 32 are connected by adopting a first supporting part 312 and a second supporting part 322, and the first supporting part 312 and the second supporting part 322 are both designed by adopting a wedge body or cuboid, so that a wedge mechanism can be formed between the two parts to convert linear motion into rotary motion, namely the axial movement of the sliding block 31 can be converted into the circumferential rotation of the rotating block 32; the design is also easier for the installation between the sliding block 31 and the rotating block 32, and only the first supporting portion 312 and the second supporting portion 322 are required to be aligned for installation.

In some embodiments, the top surface of the slider 31 is exposed to the opening of the cavity 12, so that after water is introduced, the top surface of the slider 31 can bear the total hydraulic pressure, so that the slider 31 can move smoothly in the cavity 12 along the axial direction towards the water outlet direction against the elastic force of the elastic element 33 to drive the rotating block 32 to rotate, and the second abutting portion 321 of the rotating block 32 is disengaged from the first abutting portion 21 on the water outlet member 20, so that the water outlet member 20 can rotate without obstruction and can be maintained in the rotated position.

In some embodiments, the elastic element 33 exerts a force on the slider 31 and on the rotating block 32, so as to ensure that the two can maintain a stable relative position without external forces (here, external forces include hydraulic pressure and artificial force when rotating the water outlet member 20), namely: the slider 31 is located at a position away from the rotation block 32 in the cavity 12, and the rotation block 32 is located at a position where the second abutting portion 321 abuts or almost abuts the first abutting portion 21.

In some embodiments, a seal 34 is provided between the slider 31 and the cavity 12 to prevent the water flow from overflowing between the slider 31 and the cavity 12 after water is introduced to cause deformation of the finally output water spray or dripping of the water outlet device.
