Description

The invention relates to water supply systems and can be used in water supply systems both at home and in the field in any climate in autonomous water supply systems.

The well-known shower head usually includes a supply pipe, a shower net and a water flow control mechanism (see, for example, shower head No. 58).

Known shower heads are designed taking into account the standard of water flow through the shower head existing in world practice in the range of 12-23 liters per minute (see "Problems of space biology", volume XXIV: Chizhov S.V., Sinyak Yu.E. Water supply for space crews ships, M: Nauka, 1973, pp. 16, 17). This is too much water consumption, but until now, almost none of the designers of water supply systems has solved the issue of significantly reducing this indicator by increasing the efficiency of using the water flowing from the shower head, about 90% of which is not involved in the process of washing the object or subject under the shower .

The technical result of the proposed water supply system is to reduce the flow of water through the shower head to 0.4-2 liters per minute, i.e. an average of 15 times.

This technical result is achieved by the fact that in the proposed water-saving shower head, including a supply tube, a shower net and a water flow control mechanism, said shower net is made two-part, having a peripheral section with holes of 0.2-0.5 mm with a water flow rate of up to 8 l / min and the central section in the form of a replaceable element of a water-saving aerator-nozzle with an economy function, providing a water flow of 0.4-2 l / min, and the water flow regulation mechanism is equipped with an on-off valve for alternately supplying water either through the peripheral section of the shower screen, or through replaceable element of the water-saving aerator-nozzle.

At the same time, the mentioned water flow control mechanism used in the inventive shower head includes a diaphragm, a rod movably installed in it, rigidly connected to the mentioned on-off valve, and a push lever interacting with the said rod. Said push lever is isolated from the outside of the shower head by a soft plastic cover.

In FIG. 1 shows the design of the proposed shower head; in fig. 2 shows a prototype of this shower head from the catalog mentioned above.

As seen in FIG. 1, the proposed water saving shower head includes a body 1 containing a supply pipe 2, a shower screen 3 and a water flow control mechanism, described in detail below.

In accordance with the purpose of the invention, the shower net 3 is made two-part, having a peripheral section 4 and a central section in the form of a replaceable element of a water-saving aerator nozzle 5. The peripheral section 4 of the shower net is provided with holes with a diameter of 0.2-0.5 mm with a water flow rate of up to 8 l /min, and the central section in the form of a replaceable element of a water-saving aerator-nozzle 4 with the function of saving water consumption provides water flow in the range of 0.4-2 l/min.

Said mechanism for regulating the water flow is provided with a two-position valve 6 for alternately supplying water either through the peripheral section 4 of the shower net, or through the replaceable element of the water-saving aerator-nozzle 5. In this case, the mechanism for regulating the water flow includes a diaphragm 7, a rod 8 movably installed in it, rigidly connected with a two-position valve 6, and a push lever 9 interacting with said rod 8. The push lever 9 of the water flow control mechanism is isolated from the outer space of the shower head with a soft plastic cover 10.

The proposed shower head functions as follows.

The supply of water to the shower head is carried out in a well-known way, by opening the faucet (faucets) of the mixer (not shown in the drawing), which communicates with the shower head through a flexible hose (not shown in the drawing). Through the inlet pipe 2, water enters the mechanism for regulating the flow of water. Under water pressure, the on-off valve 6 moves upward and prevents the flow of water through the diaphragm 7 to the peripheral section 4 of the shower screen 3. Water enters the object or subject under the shower through the central section in the form of a replaceable element of the water-saving aerator-nozzle 5 with the function of saving consumption water. A jet of water passing through the aerator-nozzle 5 with the function of saving water consumption is broken into tiny particles in the form of an aerosol, covering the treated object or subject with a water "torch", with a water flow rate of 0.4-2 l / min. In the washing process, every particle of water is thus involved, which significantly reduces water consumption. For example, instead of 40 liters of water for washing hands (the standard water consumption for 2 minutes), thanks to this invention, only 0.5 liters of water will be needed. For these purposes, we can use, for example, an aerator-nozzle presented in the description of the invention to the patent of the Russian Federation No. 2476273.

If it is necessary to supply water through the peripheral section 4 of the shower screen, the user presses his finger on the right end of the pressure lever 9, as a result of which the stem 8, together with the on-off valve 6 installed on it, goes down, blocking the access of water to the aerator-nozzle 5 with its lower end and opening access water through the diaphragm 7 to the peripheral section 4 of the shower screen.

Thus, the proposed shower head, being a device for a fine flow of liquid with spraying, as an output device provides an economical mode of water consumption due to a change in its phase state - transformation into an aerosol even at low pressure in the plumbing system.

A significant reduction in water consumption is achieved by spraying the liquid into a finely dispersed channel, which provides an economical mode of water consumption, even at low pressure in the plumbing system. The effectiveness of water procedures depends on the amount of sprayed water particles, so a decrease in the diameter of a drop of water leads to a reduction in its consumption.

At the same time, as shown by the experiments and the testing of water-saving aerators-nozzles and shower heads from 03/23/2019 to 05/10/2019 on the basis of military unit 61899, Moscow, Mosrentgen, on the implementation of personal hygiene rules (morning washing with brushing teeth; shaving the face ; washing hands before eating; washing, brushing teeth and washing feet before going to bed; taking a hygienic shower) (see the Charter of the Internal Service of the Armed Forces of the Russian Federation, Moscow, 2007, p. 262, art. 344), while the hygienic qualities of the procedure washes do not deteriorate. Such a finely dispersed flow of water with spraying provides, with a significant reduction (by an order of 9-11 times) from the standard values \u200b\u200bof water consumption established for the implementation of personal hygiene rules from 100 to 11 liters (actually measured water consumption by military personnel), complete sanitary and hygienic treatment of the object (human body) while maintaining the accepted habitual amenities or the subject (during decontamination and degassing of equipment and weapons). In the case of using hot water, this method improves the heating of the object being processed (hands, dishes, human body, etc.), which was confirmed by a test in which about 250 people took part in the parade of the MTO Academy, St. Petersburg, based on military unit 61899 (see Act on the results of testing water-saving nozzles on taps and shower handles in military unit 61899, Moscow, Mosrentgen, 2019, pp. 1-3, 7, 8).

While a specific embodiment of the invention has been described here for illustrative purposes, various modifications and improvements to the apparatus may be made without departing from the spirit and scope of the invention. In particular, the shower head can be made in various modifications and improvements, but must combine different water flow and form a jet of any shape and flow rate through various types and types of water flow regulators. Therefore, this invention should not be limited otherwise than by the appended claims.
