In the present embodiment, the mounting decoration ring 70 is sleeved with the dental canal 60 by interference fit through the mounting hole 70a to realize stable connection with the dental canal 60; in the direction of the central axis of the mounting hole 70a, the projection of the mounting decoration ring 70 is located in the projection of the faucet main body 10, namely the diameter of the mounting decoration ring is smaller than that of the faucet main body 10, and the mounting space required by the mounting decoration ring 70 is smaller than that of the faucet main body 10; therefore, the first end surface 70b of the decorative ring 70 is abutted against the sink rim 200, and the second end surface 70c is abutted against the faucet body 10, so that the decorative ring 70 is accommodated in the installation space formed by the sink rim 200 and is positioned between the faucet body 10 and the sink rim 200, thereby increasing the height of the faucet body 10 relative to the sink rim 200, enabling the faucet body 10 to be installed by avoiding the installation space formed by the sink rim 200, and realizing stable connection between the decorative ring 70 and the tooth tube 60, the faucet body 10 and the sink rim 200 by matching the installation hole 70a, the first end surface 70b and the second end surface 70c, thereby ensuring stable installation of the faucet body 10.

The mounting decoration ring 70 may be made of ABS (ABS is an acronym of Arylonitril Butin Styrn, and refers to an acrylonitrile-butadiene-styrene copolymer), which is a thermoplastic polymer structure material with high strength, good toughness and easy processing and forming, and is also called as ABS resin material. The faucet body 10 is also made of ABS, and the mounting decoration ring 70 is the same color as the faucet body 10 to maintain the mounting beauty of the water purifying faucet 100.

In one embodiment, the mounting trim ring 70 includes a first ring portion 71 forming a mounting hole 70a, a second ring portion 72 surrounding the first ring portion 71, and a connecting portion 73 connecting between the first ring portion 71 and the second ring portion 72. The second ring part 72 can surround the first ring part 71 at intervals through the connecting part 73, namely, an interval space exists between the second ring part 72 and the first ring part 71, so that on one hand, the material cost for installing the decorative ring 70 is reduced; on the other hand, when the mounting hole 70a is fitted over the dental tube 60 with interference, the dental tube 60 will press against the first ring portion 71, and the first ring portion 71 will deform slightly when pressed by the dental tube 60 through the space.

In one embodiment, the connecting portion 73 includes a connecting rib 731 extending from an outer peripheral wall of the first ring portion 71 to an inner peripheral wall of the second ring portion 72. The connection stability of the connecting ribs 731 to the first ring portion 71 and the second ring portion 72 can be improved by connecting the outer peripheral wall of the first ring portion 71 and the inner peripheral wall of the second ring portion 72 with the connecting ribs 731.

In some specific embodiments, the connecting rib 731 is a plurality of connecting ribs 731, and the plurality of connecting ribs 731 is arranged at intervals along the circumferential direction of the first ring portion 71. The connection between the first ring part 71 and the second ring part 72 is stably and evenly realized by arranging a plurality of connecting ribs 731 at intervals along the circumferential direction of the first ring part 71.

In one embodiment, the connecting portion 73 further includes a connecting end 732 extending from one end of the first ring portion 71 to one end of the second ring portion 72, the connecting end 732 having a first end surface 70 b. The connection stability of the connection portion 73 connecting the first ring portion 71 and the second ring portion 72 is further improved by adding the connection end 732; meanwhile, the first end surface 70b is formed by the connection end 732, so that the contact area between the first end surface 70b and the sink rim 200 is increased, and the contact stability between the installation decoration ring 70 and the sink rim 200 is improved.

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.
