Faucet aerator

Abstract

A faucet aerator comprises: a casing and a guiding member. The casing has a water inlet 11 and a water outlet. The water inlet is provided with a threaded portion for engaging with a faucet. The casing is further provided with at least one ring groove at an inner surface for engaging with the guiding member. The guiding member has a barrel body with a pre-filter, and the pre-filter is provided with at least one ring rib for engaging with the ring groove when the guiding member is placed in the casing, to avoid the guiding member from escaping the casing while the aerator is cleaned. The barrel body provided with a plurality of through apertures, a bottom mesh, and a first aerating mesh.

Claims

1. A faucet aerator consisting of: a casing, a sealing ring, a prefilter, a first aerating mesh, a second aerating mesh, and a barrel body; wherein the casing is made of copper and further monolithically forms: threads on an outer surface of the casing positioned adjacent an upstream end of the casing; a ring groove formed in a sidewall of an inner surface of the casing; a sealing ring groove formed on the outer surface of the casing positioned between the threads and a downstream end of the casing; and wherein the prefilter further monolithically forms: a first outer diameter portion, a second outer diameter portion, and a third outer diameter portion having respectively a first radial diameter, a second radial diameter, and a third radial diameter, wherein the second radial diameter is smaller than the first radial diameter and larger than the third radial diameter; a central void at least partially formed by the first, second, and third outer diameter portions; an annular ring rib formed at the first outer diameter portion; an annular ring; a frusto-conical portion which points upstream and forms an upstream sidewall of the central void; and wherein the barrel body further monolithically forms: a bottom having honeycomb holes; a plurality of through apertures; a plurality of guiding slots formed on an inner surface of the barrel body and positioned circumferentially between the plurality of through apertures; and wherein the first aerating mesh further monolithically forms: a first plurality of guiding members; and wherein the second aerating mesh further monolithically forms: a second plurality of guiding members; and wherein the sealing ring is positioned within the sealing ring groove of the casing; and wherein the annular ring rib of the prefilter is positioned within the ring groove of the casing; and wherein the annular ring is positioned between the third outer diameter portion of the prefilter and an inner surface of the casing; and wherein the first plurality of guiding members of the first aerating mesh are positioned within the plurality of slots of the barrel body; and wherein the second plurality of guiding members of the second aerating mesh are positioned within the plurality of slots of the barrel body; and wherein the barrel body is directly attached to a downstream end of the prefilter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(6) Please refer to FIG. 1 to FIG. 4. A faucet aerator comprises: a casing 10 and a guiding member 20. The casing 10 has a water inlet 11 and a water outlet 12. The water inlet 11 is provided with a threaded portion 13 for engaging with a faucet 40. The casing 10 is further provided with at least one ring groove 14 at an inner surface for engaging with the guiding member 20. The guiding member 20 has a barrel body 21 with a pre-filter 22, and the pre-filter 22 is provided with at least one ring rib 221 for engaging with the ring groove 14 when the guiding member 20 is placed in the casing 20, to avoid the guiding member 20 from escaping the casing 10 while the aerator is cleaned. The barrel body 21 provided with a plurality of through apertures, a bottom mesh 212, and a first aerating mesh 23.

(7) Furthermore, the casing 10 is made from a copper ingot.

(8) Furthermore, the ring groove 14 is disposed on the casing 10 adjacent to the water inlet 11.

(9) Moreover, the threaded portion 13 is an outer threaded section.

(10) In addition, the threaded portion 13 of the casing 10 is provided with an engaging ring groove 15, and a sealing ring 30 is jacketed on the engaging groove 15 to leakage between the faucet 40 and the casing 10.

(11) In addition, the barrel body 21 has a bottom with honeycomb holes 212.

(12) Additionally, the barrel body 21 further comprises a plurality of guiding slots 213 at the inner surface and extending beyond the through apertures 211, the first aerating mesh 23 further comprises a plurality of guiding members 231 at an outer periphery, and the guiding members 231 engage with the guiding slots 213 for securing the first aerating mesh 23 in the barrel body 21.

(13) Also, wherein the barrel body 21 further comprises a plurality of guiding slots 213 on the inner surface and extending beyond the through apertures 211, the first aerating mesh 23 further comprises a plurality of guiding members 231 at an outer periphery, and the guiding members 231 engage with the guiding slots 213 for securing the first aerating mesh 23 in the barrel body 21, and the first aerating mesh 23 is equipped with a second aerating mesh 24.

(14) Correspondingly, the ring groove 14 a guiding portion is disposed above the ring groove 14 for guiding the ring rib 221 into engagement with the ring groove 14.

(15) In actual use, water from the faucet 40 enters into the water inlet 11 of the aerator and uses the aerator to introduce air to break the water flow. When the water outlet 12 outputs a large amount of fine water, the flow rate feels larger than it actually is. With the engagement between the ring groove 14 and the ring rib 221, when the aerator is dismantled and cleaned by the finger or being overturned, the guiding member 20 is still mounted in the casing. Therefore, the use of the aerator is convenient.

(16) Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
