Description

This utility model relates to plumbing household appliances and can be used to mix water with air in mixers, faucets and other similar devices.

The closest to the claimed technical solution is an ecocrator (Patent UA 99250), comprising a housing and a disk-shaped membrane, which is made of elastic material and axially placed in the housing with a gap between the membrane mount and the wall of the housing, the membrane having at least four holes in the form of equilateral triangles whose vertices are directed to its center and which are equidistant from it and symmetrically located relative to each other. The disadvantage of this ecorator is that the membrane inside the aerator body is not centered, so it can move and an uneven jet of air-water mixture is obtained at the outlet of the aerator. And also round holes located along the length of the circle outside the membrane do not create the necessary turbulent flow on the other side of the aerator.

The problem to which the claimed utility model is directed is to create a membrane that promotes better mixing of water with air.

This problem is solved due to the fact that the claimed universal membrane for aerators has a disk-shaped shape and holes in the form of equilateral triangles, the vertices of which are directed to its center, and triangular notches are made around the circumference, directed by sharp edges to the center of the disk, while the size of the triangular holes equal to 1 × 1 × 1 mm, and the notch size is 2 × 2 × 2 mm.

The technical result provided by the given set of features is to reduce water consumption and increase the amount of oxygen in the water stream. Also, due to the notches peaks that are closely adjacent to the aerator walls, the position of the membrane is fixed, and triangular water passages create added turbulence on the other side of the membrane.

The claimed utility model is used for installation in conventional aerators, which are installed on faucets-mixers and showers in order to reduce water consumption without changing the comfort of use.

The universal membrane for aerators is designed to create a turbulent flow of water in the design of the aerator, which allows to reduce water consumption and increase in the stream, without changing the volume, the amount of air.

The essence of the utility model is illustrated by drawings, which depict:

in FIG. 1 - general view of the membrane;

in FIG. 2 is a view of a membrane with hole arrangements.

The membrane is a disk 1 of predominantly white color, made of the material "Polylit" 0.4 mm thick, with holes 2 of a triangular shape with sharp acute angles directed to the center of the circle and notches 3 of a triangular shape around the entire circumference. The dimensions of the triangular holes are 1 × 1 × 1 mm. With an increase in the size of the triangular holes more than 1 × 1 × 1 mm, the water consumption increases, and the air-water mixture has a proportion of 50 × 50, and if the holes are further enlarged, then in the air-water mixture there will be 70-80% of water and 20-30 % of air, which does not reduce water consumption. The number of holes varies depending on the purpose and degree of water saving. The membrane can be of four sizes in diameter: 12 mm, 15 mm, 17 mm, 18 mm. Notches of a triangular shape are made along the entire length of the circle, directed with a sharp edge to the center of the circle, 2 × 2 × 2 mm in size. If the notches along the edges of the membrane are more than 2 mm, they will open other holes and the water flow will increase significantly, while the savings will decrease dramatically. And if the triangular cutouts are less than 2 mm, then not all holes along the length of the circle near the edge of the top cover of the aerator will be closed and the water flow will be less, which will reduce aeration and reduce the comfort of use. Thus, the size of the notches along the edge of the edge equal to 2 × 2 × 2 mm contributes to the most practical option for saving water.

The design of the universal membrane allows water with increased pressure to pass between the notches and to create an increased vacuum at the exit with increased turbulence due to the triangular shape, which leads to better mixing of water with air and to obtain a larger air-water mixture at the outlet from the aerator.

A universal membrane according to this utility model is suitable for most aerators for a mixer, which makes them economical using a membrane without changing the design and additional costs for the manufacturer.

The device operates as follows. The universal membrane is placed under the protective mesh of a conventional aerator, after which it becomes economical.

The shape, size and location of the holes around the perimeter of the membrane and inside it give a more efficient mixing of water with air and a more economical effect.

Universal membrane for aerators is cheap to manufacture, technologically advanced, economical, and environmentally friendly.
