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.

Claims

1. An insert with a rotating mesh for aerators in sanitary fixtures, comprising a housing (1), a rotating mesh (5) having the axles (7) extending from a rim circumference, and o-ring seal (6), the housing (1) has on a lower part, two bearings (2) for receiving the axles (7) of the mesh (5) and the two axles (7) fit into the bearings (2) of the housing (1) of the insert and serve for pivotable fixing the rotating mesh (5) and thus enabeling rotation of the rotating mesh (5) around the axles (7);

the rotating mesh (5) has on an outer circumference thereof, in an upper 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.

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 mesh (5), such that the axles (7) lie on a line that passes through a center of the mesh (5).

3. The insert with a rotating mesh for aerators in a sanitary fixtures according to claim 2, wherein the axles (7) are positioned in an area of up to 10% of a diameter of the 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 mesh 5.

4. The insert with a rotating mesh for aerators in a sanitary fixtures according to claim 2, wherein the axles (7) are positioned at any point of the circumference of the mesh (5), providing that the axles (7) are in the 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 mesh (5) and the housing (1) of the insert.

7. The insert with a rotating mesh for aerators in sanitary fixtures according to claim 1, wherein the housing (1) of the insert has a groove (8) with a tooth (9) for receiving the handle (3) of the rotating mesh (5) for fixing the rotating mesh (5) in a working position.

8. 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 have an oval form, and a smaller dimension of the oval is 1% to 5% larger than a diameter of the axles (7) of the mesh (5) for easy mounting of the axles (7) in the bearing (2) and the rotation of the axes (7) in the bearing (2) and for the movement of the rotating mesh (5) in a horizontal direction of the bearings (2).

9. The insert with a rotating mesh for aerators in sanitary fixtures according to claim 1, wherein the rotating mesh (5) includes on a circumference thereof an intake channel (15) for air supply, the circumference of the rotating mesh (5) is a double wall;

a wall of an outer circumference of the rotating mesh (5) is shorter than the double wall in order to provide along an entire length of the wall an opening for the intake of the air which continues in the intake channel (15) and the inner wall ends at an upper part in a space for water spraying where small tongues (16) are provided above the inner wall of the intake channel (15).

12. The process of cleaning a rotating mesh according to claim 7, 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 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 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.

6. The insert with a rotating mesh for aerators in sanitary fixtures according to claim 6, wherein the rotating mesh (5) has in a lower part of a circumference thereof a handle (3) and in an upper part an inner space (10) which receives additional meshes, sprayers and micro screens.

10. A rotating mesh for aerators in sanitary fixtures, comprising a rotating mesh (5) fixed axially with two screws (12) directly in a body (13) of an aerator such that the rotating mesh is rotatable around an axis and an o-ring seal (6) enables sealing between the mesh (5) and the body (13) of the aerator and simultaneously fixes the mesh (5) in a working position and cleaning position;

the screws (12) function as axles (12a) to enable rotating the mesh (5) around the axis;

the mesh (5) has at a circumference thereof two holes which receive the screws (12).

11. (canceled)
