Abstract

The insert with a rotating mesh for aerators in sanitary fixtures consists of the housing (1) of an insert, the rotating screen (5) and o-ring (6). The housing (1) of an insert has at its bottom part i.e. at the water outlet of the sanitary fixture, two bearings (2) made, the rim (4) for installing a flat sealing between the sanitary fixture and the body of aerator. The rotating mesh (5) has on its rim circumference, preferentially at the most extended part of the rotating mesh (5), i.e. at the extension of diameter of the mesh (5) two axles (7) positioned which fit into the bearings (2) in the housing (1) of the insert, and serve for axle fixing the rotating mesh (5) and thus enabling the rotation of the rotating mesh (5) around the axles (7); the rotating mesh (5) has on its outer circumference, in the upper part, a groove (11) cut, in which o-ring seal (6) is installed for sealing the rotating mesh (5) to the housing (1) of the insert. Optionally, the rotating mesh (5) can include on its circumference, i.e. at the water outlet of the sanitary fixture, also the intake channel (15) for air supply. The intake of air for aeration is provided from the bottom side laterally. Optionally a rotating mesh can be installed directly in the aerator's body without an insert. In this context, the rotating mesh (5) is fixed axially with two screws (12) directly in the body (13) of the aerator in a way that it is rotatable around its axis.

First claim

The invention claimed is:

1. An insert with a rotating mesh for aerators in sanitary fixtures, comprising a housing ( 1 ), a rotating mesh ( 5 ) having axles ( 7 ) extending from a rim circumference, and an o-ring seal ( 6 ), the housing ( 1 ) has two bearings ( 2 ) for receiving the axles ( 7 ) of the rotating mesh ( 5 ) and the axles ( 7 ) fit into respective ones of the bearings ( 2 ) of the housing ( 1 ) and serve for pivotable connection of the rotating mesh ( 5 ) such that the rotating mesh ( 5 ) is rotatable around the axles ( 7 ); the rotating mesh ( 5 ) has on the rim circumference, in a second area, a groove ( 11 ) in which the o-ring seal ( 6 ) is installed for sealing the rotating mesh ( 5 ) to the housing ( 1 ) of the insert, the rotating mesh further comprising in a first area of the rim circumference thereof a handle ( 3 ), and the housing ( 1 ) includes a housing groove ( 8 ) extending therethrough with a tooth ( 9 ) for receiving the handle ( 3 ) of the rotating mesh ( 5 ) for fixing the rotating mesh ( 5 ) in a working position with the handle protruding outside of the housing through the housing groove.

2. The insert with a rotating mesh for aerators in sanitary fixtures according to claim 1 , wherein the axles ( 7 ) are formed at a widest part of the rotating mesh ( 5 ), such that the axles ( 7 ) lie on a line that passes through a center of the rotating mesh ( 5 ).

3. The insert with a rotating mesh for aerators in sanitary fixtures according to claim 2 , wherein the axles ( 7 ) are positioned in an area of up to 10% of a diameter of the rotating mesh ( 5 ) above or below, such that the line extending between the axles ( 7 ) moves up to 10% above or below from the center of the rotating mesh ( 5 ).

4. The insert with a rotating mesh for aerators in sanitary fixtures according to claim 2 , wherein the axles ( 7 ) are positioned at any point of the rim circumference of the rotating mesh ( 5 ), providing that the axles ( 7 ) are along a same line.

5. The insert with a rotating mesh for aerators in sanitary fixtures according to claim 1 , wherein the axles ( 7 ) are coupled together in one piece and are positioned between the rotating mesh ( 5 ) and the housing ( 1 ) of the insert.

6. The insert with a rotating mesh for aerators in sanitary fixtures according to claim 1 , wherein the rotating mesh ( 5 ) has within the second area an inner space ( 10 ) which receives additional meshes, sprayers and micro screens.

7. The insert with a rotating mesh for aerators in sanitary fixtures according to claim 1 , wherein the bearings ( 2 ) on the housing ( 1 ) of the insert define openings that are oval, each said oval having a larger dimension extending in a circumferential dimension of the housing and a smaller dimension, and the smaller dimension of the oval is 1% to 5% larger than a diameter of the axles ( 7 ) of the rotating mesh ( 5 ) to allow for mounting of the axles ( 7 ) in the bearing ( 2 ) and the rotation of the axles ( 7 ) in the bearing ( 2 ) and for movement of the rotating mesh ( 5 ) in a direction of the larger dimension of the bearings ( 2 ).

8. An insert with a rotating mesh for aerators in sanitary fixtures, comprising a housing ( 1 ), a rotating mesh ( 5 ) having axles ( 7 ) extending from a rim circumference, and an o-ring seal ( 6 ), the housing ( 1 ) has on a first part two bearings ( 2 ) for receiving the axles ( 7 ) of the rotating mesh ( 5 ) and the axles ( 7 ) fit into respective ones of the bearings ( 2 ) of the housing ( 1 ) and serve for pivotable connection of the rotating mesh ( 5 ) such that the rotating mesh ( 5 ) is rotatable around the axles ( 7 ); the rotating mesh ( 5 ) has on the rim circumference, in a second part, a groove ( 11 ) in which the o-ring seal ( 6 ) is installed for sealing the rotating mesh ( 5 ) to the housing ( 1 ) of the insert, wherein the rotating mesh ( 5 ) includes on the rim circumference an intake channel ( 15 ) for air supply, the rim circumference of the rotating mesh ( 5 ) includes a double wall having an inner wall and an outer wall; the outer wall is shorter than an overall height of the double wall in order to provide along an entire length of the wall an opening for intake of air which continues in the intake channel ( 15 ) and the inner wall ends at a space for water spraying where tongues ( 16 ) are provided above the inner wall of the intake channel ( 15 ).

9. The process of cleaning the rotating mesh according to claim 1 , comprising pushing the handle ( 3 ) with a finger in order to swivel the rotating mesh horizontally, with the tooth ( 9 ) loosening the handle ( 3 ) from the housing groove ( 8 ); rotating the rotating mesh ( 5 ) by pressing the handle ( 3 ) in a downward direction, to rotate the rotating mesh around the axles ( 7 ) in the bearings ( 2 ); and due to this rotation, a bottom and an upper side of the rotating mesh ( 5 ) reversing positions; exposing mechanical particles, which have been deposited inside the insert on the upper side of the rotating mesh ( 5 ) to a water current, and, with water rinsing, removing the mechanical particles from the rotating mesh ( 5 ); and after the rotating mesh ( 5 ) is cleaned, turning the rotating mesh with the help of the handle ( 3 ) in an opposite direction upwards, moving the handle ( 3 ) into the housing groove ( 8 ) so that the tooth ( 9 ) fixes the handle ( 3 ) and the rotating mesh ( 5 ) is fixed in housing ( 1 ) of the insert again in the working position.
