Water outlet structure

Abstract

A water outlet structure includes a water spray shaper and a water outlet end. The water spray shaper is rotatably arranged at the water outlet end and includes a first water passing surface, a second water passing surface, and a water flow passage. The first water passing surface and the second water passing surface are in communication through the water flow passage. The second water passing surface is located on a water inlet side when the first water passing surface is located on a water outlet side, and the first water passing surface is located on the water inlet side when the second water passing surface is located on the water outlet side. The water outlet structure produces different water spray patterns respectively when the first water passing surface is located on the water outlet side and when the second water passing surface is located on the water outlet side.

         3 . The water outlet structure according to  claim 2 , wherein the angle formed between the normal direction of the end faces of the plurality of openings and the direction of incoming water is between 1° and 10°. 
     
     
         4 . The water outlet structure according to  claim 1 , wherein at least part of the first water passing surface and/or the second water passing surface of the water spray shaper is a curved surface. 
     
     
         5 . The water outlet structure according to  claim 1 , wherein the first water passing surface and the second water passing surface are located on both sides of the same water passing panel in a thickness direction, and the water flow passage is a through hole located in the water passing panel for communicating the first water passing surface and the second water passing surface. 
     
     
         6 . The water outlet structure according to  claim 1 , wherein the first water passing surface is located on a first water passing panel, the second water passing surface is located on a second water passing panel, and the water flow passage comprises a through hole located in the first water passing panel and a through hole located in the second water passing panel. 
     
     
         7 . The water outlet structure according to  claim 6 , wherein the water flow passage further comprises a water passing cavity located between the first water passing panel and the second water passing panel. 
     
     
         8 . The water outlet structure according to  claim 7 , wherein a flow conditioning insert is provided in the water passing cavity. 
     
     
         9 . The water outlet structure according to  claim 1 , wherein a convex column extends from the first water passing surface and/or the second water passing surface in a direction away from the water spray shaper. 
     
     
         10 . The water outlet structure according to  claim 9 , wherein the convex column is located at the center of the first water passing surface and/or the second water passing surface. 
     
     
         11 . The water outlet structure according to  claim 1 , wherein an outer peripheral surface of the water spray shaper is spherical, and an inner side surface of the water outlet end is a spherical socket surface for mounting the water spray shaper. 
     
     
         12 . The water outlet structure according to  claim 11 , wherein a plurality of grooves are formed in the spherical socket surface. 
     
     
         13 . The water outlet structure according to  claim 1 , further comprising a sealing member, which is elastic and is arranged between the water spray shaper and an inner wall of the water outlet end. 
     
     
         14 . The water outlet structure according to  claim 13 , wherein the sealing member is an annular plastic sealing member, an annular rubber sealing member, or an annular silicone sealing member. 
     
     
         15 . The water outlet structure according to  claim 13 , wherein the sealing member is arranged on the outer peripheral surface of the water spray shaper, or the sealing member is arranged on the inner side surface of the water outlet end. 
     
     
         16 . The water outlet structure according to  claim 13 , wherein a gap is reserved at least in part between the outer peripheral surface of the water spray shaper and the inner side surface of the water outlet end, and the gap decreases as the water pressure increases. 
     
     
         17 . The water outlet structure according to  claim 1 , further comprising a limiting portion, which is arranged in the water outlet structure and located on the water inlet side of the water spray shaper, with an inner diameter of the limiting portion less than an outer diameter of the water spray shaper.
