Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Example (b):

referring to fig. 1 and 2, the whole structure is a local overall view of the sensor, the water inlet part is arranged above the structure, the inner side of the water inlet part is provided with a circular table top, the cutting sleeve is arranged at the inner side edge of the water inlet part along the circular table top and has a certain thickness, guide grooves are symmetrically arranged in the radial direction of the cutting sleeve, the bottom structure of each guide groove preferably adopts an inclined plane with a downward inclined structure, the installation of a limiting check ring is facilitated, and the bottom of each guide groove is also provided with a fixing clamping groove.

Referring to fig. 3, the integral limiting retainer ring is of a circular structure and is made of plastic with an elastic structure.

The radial symmetry of the spacing retainer ring is provided with a group of spacing buckles, see fig. 3 and 4, the end parts of the spacing buckles are provided with inclined downward inclination angles for facilitating the installation in the guide grooves, the two sides of each spacing buckle are provided with positioning shoulders, the width of the positioning shoulders is slightly smaller than that of the guide grooves for facilitating the positioning of the spacing retainer ring at the sleeve chuck in the water inlet part, the end surface of the spacing retainer ring above the spacing buckles is also provided with a dismounting shoulder which is provided with a protruding structure along the circumferential direction of the retainer ring body for facilitating manual kneading, when in use, the positioning shoulders are placed in the guide grooves, the dismounting shoulders on the spacing retainer ring are pressed to enable the spacing buckles to slide into the fixed clamp grooves to fix the spacing retainer ring, and as the turbine assembly is sleeved in the water inlet part below the spacing retainer ring, the turbine assembly can be substantially limited and fixed by the spacing retainer ring, see the turbine assembly of fig. 5, the maximum outer diameter of the limiting check ring is located on the circular table surface, the minimum diameter of the limiting check ring is smaller than the maximum outer diameter of the turbine assembly, and the limiting check ring fixes the turbine assembly in the water inlet part through limiting of the fixing clamping groove.
