Abstract

FIELD: for water and sanitary-hygienic procedures. SUBSTANCE: shower nozzle has a water chamber with a spray grid in the central part, hollow hand grip connected to the water supply line through a shut-off valve, as well as a cock for alternate connection of the available water chambers to the water supply line. The sprayer of the additional water chamber is made as a cylindrical vessel with a central hole in the bottom part and two tangentially disposed holes in the side walls. EFFECT: improved design. 2 cl, 4 dwg

Description

 The invention relates to sanitary equipment.

 Known shower head made in the form of a square box with separate channels for supplying hot and cold water, while the holes for supplying water alternate: one of them is connected to the channel for supplying hot water, and the other to the channel for supplying cold water [1] .

 Closest to the described by the technical essence and the achieved result is a shower head, which contains a water chamber with a water spray grill and a hollow handle connected to the water supply line and communicated with the chamber cavity through a shut-off valve mounted in the chamber [2].

 Multi-jet water supply is uneconomical. Most of the water coming from the shower head does not participate in the process of sanitary treatment of a person. It is known that 5 liters of water is enough for sanitary-hygienic treatment of a person.

 The purpose of the invention is to reduce water consumption, increase the positive impact of a hygiene procedure on a person and expand operational capabilities.

 In FIG. 1 shows a shower head in a section; in FIG. 2 shows a rotary disk of a switching tap; in FIG. 3 - spray of an additional water chamber; in FIG. 4 - spray from the side of its open end.

 The shower head contains a housing 1, consisting of two parts: a water chamber 2 and a hollow handle 3. The water chamber 2 is closed by a spray grid 4, through the openings 5 of which a multi-jet water supply is provided. The hollow handle 3 is made with an element 6 for connecting to a flexible hose of the water supply line. A shut-off valve 7 is built into the hollow handle 3, and a switching valve 8 is located in the transition zone of the hollow handle to the water chamber. The shut-off valve consists of a shut-off disk 9, a mechanism 10 for clamping the shut-off disk and sealing, and a rod 11, which passes into the actuator button 12. There are various options for the execution of the shut-off valve elements and its location. The tube 13 connects the shut-off valve 7 with the tap 8 switch. The switching tap is made in the form of a disk 14 mounted on an element 15, which acts as an axis for turning the disk 14 and the fastening means, which pulls together the main water chamber 2 with the tubular handle 3. An eccentrically located window 16 is made on the disk 14. In the water chamber 2, an additional a water chamber 17 with a tube 18 and a sprayer 19. The sprayer 19 is made, for example, in the form of a cylindrical container with a Central hole 20 in the bottom and two tangentially located holes 21 in the side walls. An additional water chamber 17 passes through the spray grid 4 and can be mounted on it, for example, with a shaped nut 22.

 The described shower head works as follows.

 Water from the supply line through a flexible hose connected to the hollow handle 3 through the element 6, enters the cavity of the handle 3, where its movement is stopped by the valve 7, which is closed in the normal state. To supply water to the chamber 2 or the additional water chamber 17, you must move the button 12 or press it. Water after squeezing the locking disk of the valve 7 through the tube 13 enters the zone of the tap 8 switch. Depending on the position of the switching tap disk, the water passes through the eccentrically located window 16 in the last one into the water chamber 2 or into the pipe 18 and then into the additional water chamber 17. Water from the chamber 2 is supplied through the openings 5 of the grate 4 in the form of a beam of thin streams.

 Water from the additional chamber 17, leaving the holes 21, swirls in the cylindrical container of the sprayer 19. Swirling water has only one outlet from the sprayer through the central hole 20 in the bottom of the sprayer 19. A stream of water leaving the hole 20 with high speed is sprayed in the form water aerosols. In this case, the water aerosol has the shape of a cone with an empty central zone.

 The described shower head by supplying it with a shut-off valve, which acts only for the time the actuator button is pressed, provides an economic mode of water consumption and two modes of water extraction: multi-jet flow through the grill of the main water chamber and water supply in the form of spraying through the opening of the additional water chamber.

 Aerosol spraying of water when using the described nozzle provides with a significant reduction in water consumption a complete sanitary-hygienic treatment of a person, and also improves heating of the human body.
