In some embodiments, an end of the first ring portion 71 distal from the connection end 732 forms a first sub-end surface 70c1, and an end of the second ring portion 72 distal from the connection end 732 forms a second sub-end surface 70c 2; wherein the first sub end surface 70c1 is flush with the second sub end surface 70c2 to form the second end surface 70 c. The first sub end surface 70c1 and the second sub end surface 70c2 are arranged to be flush, so that the first sub end surface 70c1 and the second sub end surface 70c2 are abutted to the tap main body 10, namely, the first end surface 70b is formed by the first sub end surface 70c1 and the second sub end surface 70c2, and the abutting area of the first end surface 70b to the tap main body 10 is the sum of the area of the first end surface 70b and the area of the second end surface 70 c.

It should be noted that the first sub-end surface 70c1 may be higher than the second sub-end surface 70c2, i.e., the first sub-end surface 70c1 is the first end surface 70 b; alternatively, the second sub-end surface 70c2 is higher than the first sub-end surface 70c1, i.e., the second sub-end surface 70c2 is the first end surface 70 b.

In some specific embodiments, the first end surface 70b is provided with a non-slip structure. By adding the anti-slip structure, the friction force between the first end surface 70b and the sink side 200 is increased, so as to ensure the stability of the installation decoration ring 70 relative to the sink side 200, thereby improving the installation stability of the water purification faucet 100 relative to the sink side 200. It should be noted that the anti-slip structure may be configured as, but not limited to, anti-slip stripes and anti-slip bumps.

In some specific embodiments, the outer peripheral wall of the second ring portion 72 is provided with a non-slip structure. Through addding anti-skidding structure, increase the frictional force between second ring portion 72 and hand or the operation instrument, prevent to exert the phenomenon of skidding to appear between the external force of second ring portion 72 and the second ring portion 72 to guarantee to realize smoothly installing the connection of dress trim ring 70 and dental canal 60. It should be noted that the anti-slip structure may be configured as, but not limited to, anti-slip stripes and anti-slip bumps.

In some specific embodiments, the inner circumferential wall of the mounting hole 70a is provided with a screw structure for screw-coupling with the dental tube 60. Through setting up the stable connection of mounting hole 70a with dental canal 60, not only can make things convenient for the cup joint of the relative dental canal 60 of smooth and easy mounting hole 70a simultaneously.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
