Description

The invention relates to sanitary-technical water-distributing devices and can be used in distribution systems for domestic and drinking water for hygienic and other purposes, where water taps, shower heads, as well as all other similar products of water-folding fittings of all types and diameters, from various materials are used.

When developing modern sanitary-technical water-distributing devices, the main goal of the developers is to reduce the useful water flow rate at the outlet of the drain pipe of a water tap or shower head, for which they install various water-saving output devices.

The new technology, which should be introduced in order to reduce the consumption of fresh water and its costs, is aimed at a sharp increase in efficiency in the consumption of water during individual use, as well as in the service sector and the national economy, that is, industry and agriculture, utilities. Using it, you can increase the level of water consumption, when performing sanitary-hygienic measures, up to 30-50 liters of fresh water per person per day. The essence of this project is to reduce water consumption by the end user, bringing this consumption to an average of 0.5 liters for washing, up to 5 liters for showering, and this will bring benefits to both suppliers and consumers of water.

The technical essence of the proposed technology lies in the development of a universal water-saving nozzle for a water tap, including “European-style”, and for a shower handle that provides a flow rate of 0.375 to 1 liter per minute when washing, taking a shower, washing dishes, etc. and allowing to drastically reduce water consumption while maintaining the usual level of comfort, equivalent to a flow rate of 6-9 liters per minute. All the currently known water-folding fittings have a water output of 6-12 liters per minute or more, while most of the water coming from the tap, mixer and shower is not involved in the processing of the object (this is about 95%). A significant reduction in water consumption is achieved due to the fact that, passing through a water-saving nozzle, the water jet breaks up into tiny particles and leaves the nozzle in the form of an aerosol, covering the workpiece during washing with a “water torch”; at the same time, a positive effect is achieved during sanitary-hygienic procedures, when a finely dispersed solution and adhesive properties of the skin ensure its good wettability and almost all the water entering the procedure is used completely, and does not drain into the sewer. Such water-saving nozzles are convenient and safe to operate in water supply networks with a normal inlet pressure of 0.9 to 8 bar. They can also be operated regardless of the pressure in the water supply network, since the universal water-distributing nozzle of the water-saving type shows its flushing ability by increasing the flow rate of water. And in connection with this, as well as the fact that water is a renewable resource, and oil and gas are not, a unique opportunity has arisen to take enormous energy resources from it without harming nature.

The well-known universal water-saving nozzle [1] for water dispensers, such as a water tap (household faucet), shower head, as well as all other similar products of water-folding fittings of all types and diameters, made of various materials, includes an axially mounted tubular housing and it contains a disk filter and a device for reducing water consumption by breaking it into tiny particles in the form of an aerosol and increasing the flow rate of water with the simultaneous formation of a jet of its mode of consumption, set the output disc filter.

The disadvantage of this nozzle, as shown by its use in domestic conditions, is that its device for reducing water consumption is made in the form of several disparate, i.e. unrelated elements inserted during assembly into the specified tube-like housing individually in a specific order. This causes considerable inconvenience to the consumer during operation of the nozzle, since in the event of failure of one of the elements (and most often it happens with the lattice element at the exit of the nozzle), to replace it, it is necessary to remove all elements from the tube-like housing in turn, and when installing new elements, the consumer may confuse them in places. All this can cause the consumer significant costs of personal time and, accordingly, dissatisfaction with the goods.

The aim of the invention is to remedy this drawback. The technical result of the invention is to improve the operational properties and consumer qualities of the product.

The specified technical result is achieved by the fact that in a universal water-saving nozzle for water dispensing devices, such as a water tap (household faucet), shower head, as well as all other similar products of water-folding fittings of all types and diameters, made of various materials, including installed in the axial direction a tube-shaped housing and a disk filter and a device located therein for reducing water consumption by breaking it into tiny particles in the form of an aerosol and increasing the water flow rate simultaneous formation of jets of different flow regime it said device for reducing the water flow rate set by the output disc filter, designed as a hollow shank, freely insertable into said housing to trubkovidny spout defined therein by means of exposure to flowing water through the nozzle flow. As a means of influencing the water flow passing through the nozzle, a disk with through channels is installed at the inlet of the said hollow sleeve in the plane perpendicular to the water flow, and a lattice element with 2, 3 is installed at the outlet of the said hollow sleeve in the plane perpendicular to the water flow I, 4, 5, 6, 7, 7, 8, 9, 10, 11, 12, 12, 13, 14, 15 , 16th, 17th, 18th, 19th, 20th, etc. holes of any configuration. The distance between said disk with through channels and said lattice element is 0.2-0.4 from the inner diameter of this part of the hollow sleeve, and the distance between said disk filter and disk with through channels is 0.1-0.3 from the inner diameter of this parts of the hollow sleeve. The ratio of the distance between said disk filter and a disk with through channels to the distance between the disk and said lattice element is 0.6-0.8. The through channels of the said disk are made inclined to its end surface in the tangential direction in the form of slots extending from the periphery in the direction of the radius of the disk.

Figure 1 shows the drain pipe 1 of a faucet with a universal water-saving nozzle installed on it according to the present invention with the image of a flowing stream of water; figure 2 is an enlarged sectional view along aa of figure 1 of a universal water-saving nozzle according to the present invention, an embodiment with an external thread at the end of a water tap; figure 3 is a view similar to that shown in figure 2, but with an internal thread at the end of the water tap; figure 4 is a perspective (three-dimensional) image with a spatial separation of the details of figure 2.

As can be seen from figure 1, the drain pipe 1 of the water tap is equipped with a universal water-saving nozzle 2 according to the present invention. The water-saving nozzle 2 (see FIGS. 2 and 4) includes an axially mounted tube-shaped housing 3 and a disk filter 4 located therein and a device 5 for reducing water consumption while simultaneously forming a stream of various shapes - flare, lucid, etc. and a different mode of its flow rate, installed at the output of the disk filter 4. The reduction of the water flow rate of the device 5 is based on the principle of breaking it into tiny particles in the form of an aerosol and increasing the water flow rate, which is described in more detail below.

In accordance with the purpose of the invention, said device 5 for reducing water consumption is made in the form of a hollow sleeve 6, commonly referred to as a “thimble” and freely inserted into said tube-shaped body 3 at a spout. In the hollow sleeve 6 of the device 5 to reduce water consumption, appropriate means are installed to influence the flow of water passing through the water-saving nozzle 2.

As a means of influencing the flow of water passing through the nozzle included in the design of the device 5 to reduce water consumption, a disk 8 with through channels 9 is installed at the inlet of the said hollow sleeve 6 in a plane perpendicular to the water flow, and at the outlet of the said hollow sleeve in the plane perpendicular to the water flow, a lattice element 10 is installed with 2, 3, 4, 5, 6, 7, 7, 8, 9, 10, 11 Tew, 12 Tew, 13 Thw, 14 Thw, 15 Thw, 16 Thw, 17 Thw, 18 Thw, 19 Thw, 20 Thw, etc. holes in any configuration. Through channels 9 of said disk 8 are made inclined to its end surface. Preferably, the inclination of the channels 9 was in the tangential direction, and the channels 9 themselves were made in the form of slots extending from the periphery in the direction of the radius of the disk 8.

It is also preferable that in the proposed water-saving nozzle the following size ratios are maintained: the distance between the said disk 8 and the lattice element 10 is within 0.2-0.4 of the inner diameter of this part of the hollow sleeve 6; the distance between the disk filter 4 and the disk 8 with through channels is within 0.1-0.3 of the inner diameter of this part of the hollow sleeve 6; the ratio of the distance between the disk filter 4 and the disk 8 to the distance between the disk 8 and the lattice element 10 is in the range of 0.6-0.8.

Installing the water-saving nozzle 2 on the outlet end of the drain pipe 1 is carried out by screwing it onto the drain pipe until it stops against the outer end of the drain pipe 1 in the o-ring 11. The nozzle is also mounted on the shower handle (not shown). If the end of the drain pipe 1 has an internal thread (Fig. 3), then the water-saving nozzle 2 is installed by screwing it into the drain pipe until it stops, the sealing ring 12 into the inner ledge 13, which ends the internal thread at the end of the drain pipe 1.

The described universal water-saving nozzle operates as follows. The jet of water entering through the drain pipe 1 or through the internal channel of the shower handle (not shown in the drawing) to its outlet, passing through the disk filter 4 and the inclined channels 9 of the disk 8, is twisted in the space between the disk 8 and the lattice element 10, which can be called a swirling chamber, is divided into the smallest particles in the form of an aerosol, then, to enhance this effect, the smallest particles of water pass through the holes of the lattice element 10 installed at the outlet, covering the workpiece with a water “torch”. In the washing process, thus, each particle of water is involved, which significantly reduces water consumption. For example, instead of 40 liters of water for washing hands (standard water consumption in 2 minutes), thanks to this invention, only 0.5 liters of water will be needed.

Thus, the described universal water-dispensing nozzle, which is a device for fine dispersion of liquid, as an output device provides an economical mode of water consumption by breaking it into tiny particles in the form of an aerosol even at low pressure in the water supply system. Moreover, as experiments have shown, the hygienic qualities of the washing procedure do not deteriorate. Such spraying provides with a significant reduction in water consumption a complete sanitary-hygienic treatment of the object, and in the case of using hot water it improves the heating of the treated object (hands, dishes, human body, etc.).

Since the device for reducing the flow of water in the proposed water-distributing nozzle is made in the form of a hollow sleeve 6 that can be freely inserted into the said tube-shaped body 3 with means installed for influencing the water flow passing through the nozzle (instead of several disparate, i.e., not connected to each other elements), this will provide the consumer with the operation of the nozzle significant convenience. So, if one of the elements of the hollow sleeve 6 fails, it is replaced with a new, usually spare, sleeve, without the need for detailed disassembly of the device to reduce water consumption. Thus, the cost of personal time to restore the normal operation of the nozzle at the consumer will be significantly reduced.

Although a specific embodiment of the invention is described herein for illustrative purposes, various modifications and improvements to the device may be made without departing from the spirit and scope of the invention. In particular, the universal water-saving nozzle can be made in various modifications and improvements, but must combine a different water flow and form a stream of any shape and flow rate through various types and types of water flow controllers. Therefore, this invention should not be limited by anything other than the attached claims.
