Description

The invention relates to the construction of sanitary equipment. The proposed nozzle can be used with household mixers or water taps in housing and communal services, as well as in public places, in medical and kindergartens, as well as schools to save water consumption when using plumbing systems.

The prototype of this invention is a water tap with a valve retainer consisting of a body, a stem with a rigidly fixed nipple, a ball valve, a washer with a socket for a ball valve, a spring, and a sleeve with holes for water flow [1]. With the application of the user's hand effort from the bottom up to the nipple of the faucet, a spherical valve opens, and water is poured from the faucet for water consumption.

The main disadvantages of the prototype is the complexity of the design, the use of a spring in this device, which significantly reduces the reliability and durability of the product as a whole, as well as the need for a significant user hand to open the water supply.

The aim of the invention is to simplify the design of the nozzle, increasing the reliability and durability of the product as a whole, as well as reducing the user's hand effort to open the water supply.

The invention consists in the following.

Due to the small number of structural elements of the product, the design of the nozzle is simplified, and the rejection of spring elements increases the reliability of operation and durability of the product as a whole. The implementation of the end of the stem of the push rod at an angle and the presence of an insert having an upper end portion in the form of an internal cone, ending with a valve bore in the form of an opening, allows the ball-valve to freely move through the internal cone, as well as using a guide ring with a guide hole held on the legs, significantly reduce the force applied by the user's hand necessary to open the ball-valve and, accordingly, the water supply to the consumer.

The solution of the problem is achieved by implementing a new design of the nozzle on the faucet or mixer. Graphic material explaining the invention is presented in the following figures:

FIG. 1 - nozzle body, vertical section;

FIG. 2 - nozzle housing, top view;

FIG. 3 - an insert, a section by a vertical plane;

FIG. 4 - insert, bottom view;

FIG. 5 - pusher rod with a rigidly fixed nipple;

FIG. 6 - nozzle on the crane or mixer in the collection, the cut vertical plane;

FIG. 7 - nozzle on the faucet or mixer with a filled upper cavity, the phase of readiness to supply water for consumption;

FIG. 8 - nozzle on the faucet or mixer in the phase of water supply for consumption needs.

The nozzle consists of a nozzle body 1 of cylindrical shape, in the upper part of which there is a thread 2 of internal or external design for mounting on a faucet or mixer (Fig. 1). In the center of the bottom wall 3 of the nozzle is located a guide hole 4 and multiple perforated holes 5 for the passage of water (Fig. 1, 2). On the inner wall of the upper part of the housing of the nozzle 1 there is a supporting step 6 (Fig. 1), on which the insert 7 is supported (Figs. 3, 4, 6). The insert 7 has an upper end part in the form of an internal cone 8 (FIG. 3, 4), ending with a valve seat in the form of an opening 9 and a ledge 10 (FIG. 3) for laying the sealing gasket 11 (FIG. 6). From the opposite end of the insert 7 on the legs 12, the guide ring 13 is held with the guide hole 14 (Fig. 3, 4). In the guide hole 4 of the body of the nozzle 1 (Fig. 1, 2) and the guide hole 14 of the guide ring 13 of the insert 7 (Fig. 3, 4), the push rod 15 (Fig. 5, 6) freely walks. At the end of the pusher rod 15 (Fig. 5, 6), coming out of the body of the nozzle 1 to the outside, the nipple 16 is rigidly fixed. From the inner end, the pusher rod 15 has a shank 17 with a diameter larger than the diameter of the pusher rod 15 and with the end face 18 cut at an angle in the form of an oblique flat cut. In the upper cavity 19 of the insert 7 above the inner cone 8 (Fig. 3, 6) is placed a ball-valve 20 (Fig. 6) with the possibility of free movement in this cavity 19.

The nozzle assembly (Fig. 6) is fixed by means of the nozzle body 1 through the sealing gasket 21 to the faucet or the faucet through the threaded connection 2 of internal or external performance, depending on the design features of the faucet or the faucet. The ball-valve 20, being in a free state, under the influence of gravity will lie in the valve seat in the form of a hole 9 (Fig. 3) on the sealing gasket 11, blocking this hole 9.

When the valve of the faucet or mixer is opened, the water under pressure fills the entire volume of the upper cavity 19 of the insert 7 (Fig. 7). Under the influence of the hydrodynamic pressure of water generated in the upper cavity of the nozzle 19 and the force of gravity acting on the ball-valve 20, the ball-valve 20 hermetically closes the valve seat in the form of the hole 9 of the insert 7, by means of a sealing gasket 11, thereby preventing water from entering the lower volume 22 of the nozzle body 1.

Due to the larger diameter of the shank 17, than the diameter of the rod-pusher 15, the movement of the rod-pusher 15 down is limited (Fig. 6, 7).

In order to supply water for consumption, it is necessary for the user to apply a vertical force with the hand to the rigidly fixed nipple 16 of the push rod 15 (Fig. 8). As a result, the pusher rod 15 moves vertically upward, acting by the end face 18 of the shank 17 of the pusher rod 15 on the ball-valve 20, tearing it away from the sealing gasket 11. As a result, the valve seat opens in the form of an opening 9 of the insert 7, thereby providing water access in the lower volume 22 of the nozzle housing 1. The pressure in the upper cavity of the nozzle 19 and the lower volume 22 of the nozzle housing 1 is leveled, water is poured out through the perforated holes 5 of the bottom wall 3 of the nozzle housing 1 to the outside for water consumption in the form of water jets 23 ( Fig. 8).

Due to the execution of the end face 18 of the shank 17 in the form of an oblique flat cut, the contact spot of the surface of the end face 18 of the shank 17 with the ball-valve 20 is displaced from the vertical axis of symmetry in the radial direction to the maximum possible distance (FIGS. 6, 7, 8), which creates an additional rotating the moment that reduces the required applied force for the separation of the ball-valve 20 from the sealing gasket 11 and the opening of the valve seat in the form of a hole 9.

To close the water supply for consumption through the nozzle, it is necessary to stop the user's hand on the rigidly fixed nipple 16 of the pusher 15. As a result, the pusher 15, under the influence of gravity, moves down until the shank 17 contacts the guide ring 13 of the insert 7. The impact on the ball-valve 20 from the side of the pusher rod 15 stops, and the ball-valve 20 as a result of rolling under the action of gravity rushes along the walls of the inner cone 8 into the valve seat in the form of an opening 9 (Fig. 7) . As a result of the action of the hydrodynamic pressure of water and gravity on the ball-valve 20, the valve seat is blocked in the form of an opening 9 of the insert 7 by means of a sealing gasket 11, thereby stopping the supply of water for consumption. The nozzle on the faucet or mixer returns to the readiness phase of the water supply for consumption needs (Fig. 7).

Due to the execution of the upper end part of the insert 7 in the form of an internal cone 8 (Fig. 3, 6), ending with a valve seat in the form of an aperture 9, the free movement of the ball-valve 20 to its initial state is ensured, moreover, the design is simplified, and also ease of opening and tightness when closing the valve seat in the form of a hole 9. Using the guide hole 14 in the guide ring 13 on the tabs 12 (Fig. 3, 6, 7, 8) and the guide hole 4 of the nozzle body 1 (Fig. 1, 2) facilitates significantly ho d rod-pusher, simplifies the design of the nozzle and increases its reliability.

The proposed nozzle design requires significantly less effort from the user's hand on the pusher rod 15 attached to the nipple 16 to displace the ball-valve 20 and then open the valve seat in the form of an opening 9. This effect is achieved by displacing the contact spot radially away from the vertical axis of symmetry, creating thereby additional torque and thereby providing tilting of the ball-valve 20 to the side with the subsequent opening of the valve seat in the form of an opening 9 for the smooth passage of water h Through the nozzle.
