Aerator

Abstract

An aerator includes a tubular shell and an inner container; an inner wall of the tubular shell being provided with through slots disposed to pass through the tubular shell along an axial direction of the inner wall; and an outer wall of the inner container being provided with limiting ribs and a convex lip, the limiting ribs being distributed along an axial direction of the inner container and being matched with the through slots, and the convex lip being located on a water outlet end of the inner container and being pressed against end surfaces in an axial direction of the tubular shell. According to the present application, the stable connection between the inner container and the tubular shell is ensured, at the same time, the structure of the tubular shell is simplified, the production difficulty is lowered, and the production cost is reduced.

What is claimed is:

 an inner wall of the tubular shell being provided with through slots disposed to pass through the tubular shell along an axial direction of the inner wall; and   an outer wall of the inner container being provided with limiting ribs and a convex lip, the limiting ribs being distributed along an axial direction of the inner container and being matched with the through slots, and the convex lip being located on a water outlet end of the inner container and being pressed against end surfaces in an axial direction of the tubular shell.   
     
     
         2 . The aerator according to  claim 1 , wherein the limiting ribs are in transition or interference fit with the through slots. 
     
     
         3 . The aerator according to  claim 1 , wherein each of the limiting ribs is provided with at least two first guide slopes symmetrically disposed along the axial direction of the inner container, and the first guide slopes are gradually protruded from a water inlet end to the water outlet end of the inner container. 
     
     
         4 . The aerator according to  claim 3 , wherein each of the limiting ribs is provided with at least two second guide slopes symmetrically disposed along the axial direction of the inner container, the second guide slopes and the first guide slopes are symmetrically disposed along a radial direction of the inner container, and the second guide slopes are gradually protruded from the water outlet end to the water inlet end of the inner container. 
     
     
         5 . The aerator according to  claim 4 , wherein the first guide slopes are in smooth transition connection with the second guide slopes by connecting surfaces, and the connecting surfaces are pressed against circumferential inner walls of the through slots. 
     
     
         6 . The aerator according to  claim 1 , wherein the convex lip is an annular convex lip. 
     
     
         7 . The aerator according to  claim 1 , wherein the convex lip comprises at least two limiting bodies uniformly distributed on a circumferential outer wall of the inner container. 
     
     
         8 . The aerator according to  claim 1 , wherein each of the water inlet end and the water outlet end of the inner container is provided with the convex lip. 
     
     
         9 . The aerator according to  claim 1 , wherein the inner container comprises a water inlet body and a water outlet body coaxial with the water inlet body, the water inlet body is detachably connected to the water outlet body, and an outer wall of each of the water inlet body and the water outlet body is provided with the convex lip. 
     
     
         10 . The aerator according to  claim 8 , wherein a gap is formed between at least one of the convex lips and one of the end surfaces in the axial direction of the tubular shell. 
     
     
         11 . The aerator according to  claim 9 , wherein a gap is formed between at least one of the convex lips and one of the end surfaces in the axial direction of the tubular shell.
