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.

A universal membrane for aerators is known from the prior art (Utility Model Patent RU 174135, published on 10/03/2017 Bull. No. 28), which has a disk-shaped shape and a hole in the form of an equilateral triangle in the center of the membrane, and triangular notches are made around the membrane circumference, directed by sharp edges to the center of the disc.

The tolerances in aerators, shower heads and end taps are different and gaps may form when using a membrane of a certain size, which leads to a displacement of the membrane inside the installation site, which in turn worsens the membrane and makes a non-uniform water stream at the water outlet from the device.

Another disadvantage of this membrane is the presence of three sizes 15 mm, 17 mm, 18 mm.

The problem to which the claimed utility model is directed is the development of a device for installation in a mixer, contributing to better mixing of water with air.

This problem is solved due to the fact that the universal membrane for plumbing fixtures has a disk-shaped shape and at least three holes in the shape of an equilateral triangle in the center of the device, and protrusions are located around the membrane circumference, located at equal distance from each other and having between them smooth parts of a circle. The protrusions can be made as a triangular shape, and in the form of a trapezoid.

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 peaks of the notches closely adjacent to the walls of the plumbing fixture, the position of the membrane is fixed, and the water passages formed between the notches create additional turbulence on the other side of the device.

The claimed utility model is used to install down the spout of the tap, which saves water up to 50-60% without changing the comfort of use.

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

The essence of the utility model is illustrated by drawings (Fig.1,2), which depict examples of the implementation of the device.

The universal membrane for plumbing fixtures is a disk 1 with a thickness of 0.4 mm, with holes 2 triangular in shape with directed sharp angles to the center of the circle and protrusions 3 around the circumference. The protrusions can be made as a triangular shape, and in the form of a trapezoid. The protrusions also serve to center the device in the seat. The number of holes can be from three to six, depending on the purpose and degree of water saving. At least eight notches are made around the circumference of the membrane, while the notches are located at an equal distance from each other.

The design of the universal membrane allows water with increased pressure to pass between the protrusions and create an increased vacuum at the outlet with increased turbulence, which allows better mixing of water with air and obtaining a more volumetric flow of the air-water mixture at the outlet of the aerator.

The universal membrane is installed in the aerator or shower hose.

The device operates as follows. The universal membrane is placed in the spout at the outlet of water from the tap or shower head, after which it becomes economical.

The universal membrane is installed under the protective mesh or gasket of any type of aerator to its size. After installing an aerator with a membrane on the water supply device, the water consumption is reduced by an average of 35-60% (depending on the water pressure in the system) and part of the water is replaced by air, without changing the comfort of use. A steady effect is observed throughout the entire life cycle. The membrane is not subject to wear.

The saving effect is created due to:

- creating excess pressure in front of the membrane;

- increased turbulent movement of water through triangular passages;

- on the other side of the membrane, an increased vacuum is created in the aerator body (compared to a conventional aerator), due to which air is sucked in and in the lower part of the aerator through special holes and mixed with water;

- at the outlet of the aerator with a membrane, a water-air mixture is obtained, consisting of two-thirds of the air and one-third of the water, which does not affect the comfort of use.

The shape, size and location of the holes gives a more efficient mixing of water with air and a more economical effect.

This device is manufactured in one standard size, namely with a diameter of 19 mm.

If the mixer is smaller in diameter than the membrane, then the protrusions of the membrane are cut to fit the size of the mixer.

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