Abstract

The present disclosure discloses a self-cleaning water outlet device, which comprises: a body, a deposit removal needle plate disposed in the body, a water outlet cover comprising a plurality of water outlet holes, and a rotatable member driven about an axial direction of the rotatable member by flowing water. An axial direction of the deposit removal needle plate and an axial direction of the water outlet cover are coaxial, and the deposit removal needle plate has a plurality of needles. The deposit removal needle plate is swingably connected with the rotatable member. When water flows into the water outlet device, the water flow drives the rotatable member to rotate, and the rotatable member drives each of the plurality of needles to swing about the axial direction of the deposit removal needle plate in a corresponding one of the plurality of water outlet holes.

the deposit removal needle plate comprises a plurality of needles and at least one flow hole, wherein the at least one flow hole is offset from the plurality of needles,
the deposit removal needle plate is swingably connected to the rotatable member,
each of the plurality of needles defines a solid structure, and
when water flows into the self-cleaning water outlet device:
the water drives the rotatable member to rotate continuously,
the water flows through the at least one flow hole and a clearance between the plurality of needles and inner walls of the plurality of water outlet holes,
a lower side of the deposit removal needle plate are filled with the water flowing from the at least one flow hole,
the rotatable member drives the plurality of needles to swing continuously about the axial direction of the deposit removal needle plate in the plurality of water outlet holes, and
the plurality of needles rub against sediment deposited on the inner walls of the plurality of water outlet holes while the plurality of needles are swinging to dislodge the sediment.

2. The self-cleaning water outlet device according to claim 1 , wherein:
the body comprises an oblique water body,
the oblique water body comprises a chamber,
in an axial direction of the chamber, a first end of the chamber is disposed with a water inlet, and
a sidewall of the chamber is disposed with a plurality of oblique water outlets arranged along a circumferential direction of the chamber.

3. The self-cleaning water outlet device according to claim 2 , wherein:
the rotatable member is an impeller disposed outside of the sidewall of the chamber,
the water flows into the impeller from the plurality of oblique water outlets, and
blades of the impeller are impacted to drive the impeller to rotate by the water.

4. The self-cleaning water outlet device according to claim 3 , wherein:
a first side of the impeller facing the deposit removal needle plate extends downward in the axial direction of the rotatable member to form a cam,
a first side of the deposit removal needle plate facing the oblique water body extends upward in the axial direction of the deposit removal needle plate to form a connecting member,
the cam is disposed in the connecting member, and
a sidewall of the cam abuts a sidewall of the connecting member to define a swing connection.

5. The self-cleaning water outlet device according to claim 4 , wherein:
the impeller is disposed with a water outlet at, in the axial direction of the rotatable member, a lower end of the impeller,
the water flows out from the plurality of oblique water outlets, enters into the impeller, flows out from the water outlet, and then flows to the deposit removal needle plate,
the at least one flow hole is disposed in the axial direction of the deposit removal needle plate, and
the water flows from the at least one flow hole into the plurality of water outlet holes.

6. The self-cleaning water outlet device according to claim 5 , further comprising:
a movable member, wherein:
the movable member is driven by the water and moves in an axial direction of the body,
the deposit removal needle plate and the movable member are connected in the axial direction of the body, and
when the water flows into the self-cleaning water outlet device:
the water flows to drive the movable member to drive the deposit removal needle plate to move downward in the axial direction of the body, and
the plurality of needles move into the plurality of water outlet holes.

7. The self-cleaning water outlet device according to claim 6 , wherein:
in the axial direction of the chamber, a second end of the chamber away from the water inlet is disposed with a through hole,
a first end of the movable member passes through the through hole and abuts the deposit removal needle plate and is linked to the deposit removal needle plate,
a second end of the movable member is disposed in the chamber, and
when the water flows from the water inlet into the chamber:
an impact force generated by the water flowing on the movable member drives the movable member to move downward in the axial direction of the chamber.

8. The self-cleaning water outlet device according to claim 7 , wherein:
in an axial direction of the cam, the cam is disposed with a locating hole, and
the movable member is inserted into the connecting member through the locating hole and abuts, in the axial direction of the cam, a bottom end surface of the connecting member.

9. The self-cleaning water outlet device according to claim 8 , wherein:
a reset member is disposed between the deposit removal needle plate and the water outlet cover, and
when the deposit removal needle plate moves downward in the axial direction of the deposit removal needle plate, the reset member accumulates an elastic reset force.

10. The self-cleaning water outlet device according to claim 9 , wherein:
the second end of the movable member is a water storage end, and
when no water flows into the chamber from the water inlet:
the reset member drives the deposit removal needle plate to move upward in the axial direction of the deposit removal needle plate, and
the water storage end moves upward, in an axial direction of the movable member, toward the water inlet.

11. A swinging water outlet device, comprising:
a body,
a flowing water switchable member disposed in the body,
a water outlet cover comprising a plurality of water outlet holes, and
a rotatable member driven to rotate about an axial direction of the rotatable member by flowing water, wherein:
