Abstract

The present disclosure discloses an anti-splash water outflow device comprises a water outflow body and an internal assembly. The internal assembly comprises an inner body that is rotatable relative to the water outflow body upon being impacted by water. The inner body is disposed with at least two spiral blades, and two adjacent spiral blades of the at least two spiral blades define a spiral water passage. The water flows into the water outflow body from the water inlet to impact the inner body to drive the inner body to rotate relative to the water outflow body, and the water flows through the spiral water passage, flows out of the outlet of the spiral water passage, flows spirally downward along an inner wall surface of the water outflow body, and sprays out of the water outlet to obtain an annular water spray shaped as a lampshade.

First claim

What is claimed is:

1. An anti-splash water outflow device, comprising:
a water outflow body comprising a water inlet and a water outlet, and
an internal assembly disposed in the water outflow body, wherein:

the inner body is disposed with at least two spiral blades,
two spiral blades of the at least two spiral blades define a spiral water passage,
an inlet of the spiral water passage is in communication with the water inlet,
an outlet of the spiral water passage is in communication with the water outlet,
the water flows into the water outflow body from the water inlet to impact the inner body to drive the inner body to rotate relative to the water outflow body,
the water flows through the spiral water passage, flows out of the outlet of the spiral water passage, flows spirally downward along an inner wall surface of the water outflow body, and sprays out of the water outlet to obtain an annular water spray shaped as a lampshade,
the internal assembly further comprises a connecting body,
the connecting body comprises a water passage configured to be in communication with the water inlet and the water outlet,
the spiral water passage surrounds the water passage, and
when the water flows into the anti-splash water outflow device:
the water from the water inlet flows into the water passage and the inlet of the spiral water passage concurrently, and
the inner body and the connecting body rotate synchronously due to the water applied on the at least two spiral blades.

2. The anti-splash water outflow device according to claim 1 , wherein the outlet of the spiral water passage and the water outlet of the water outflow body define a first gap.

3. The anti-splash water outflow device according to claim 2 , wherein:
the connecting body is connected to the water outflow body, and
the inner body movably surrounds an outside of the connecting body.

4. The anti-splash water outflow device according to claim 3 , wherein:
a partition board is disposed in the water outflow body, and
the connecting body is disposed on the partition board.

5. The anti-splash water outflow device according to claim 4 , wherein:
the partition board extends upward to define a protruding column,
the protruding column comprises a through hole,
