Description

The invention relates to sanitary devices, in particular, to shower heads for a plumbing shower, and is intended for use mainly in domestic bathtubs, as well as physiotherapy departments of clinics, hospitals and spa salons, in order to carry out hydromassage procedures and to obtain various acupuncture effects on different parts of the human body.

A known shower head comprising a housing with a flow chamber located in it and permanently connected to the housing by a jet forming mesh with conical profile holes, the housing being equipped with a partition and the flow chamber equipped with a freely moving spherical body, the diameter of which is not less than the inner diameter of the outlet openings of the jet forming mesh [1] .

The disadvantage of this device is the lack of the ability to replace the jet forming mesh, the need for which can be caused both by clogging of the nozzle openings and by matching the flow characteristics of the pressure system with the high-pressure head of the jets formed by the shower head, necessary for hydromassage procedures and the corresponding water acupuncture effect.

In addition, the use of conical profile holes in the jet-forming grids of shower heads does not provide the maximum kinetic energy of the jets [2], which, in turn, does not allow to achieve the maximum effect from hydromassage procedures in terms of achieving the corresponding water acupuncture effect due to the inability to obtain maximum hydrodynamic pressure of the jets on the treated surface.

Closest to the claimed technical essence and the achieved result, the known solution, selected as a prototype, is a shower head containing a nozzle for supplying water made of polymeric materials, a housing, a threaded nut connected to it and fixed with it and installed inside the housing of two types of jet-forming grids made with a ┼ or ┬ shaped profile, the vertical section of which is made solid, including spherical, used to accommodate 19 or 61 nozzles holes of the conoidal profile and output diameters of the submillimeter section, and its horizontal section is for placing an o-ring of elastic material mounted on the corresponding diameter of the lower vertical part of the ┼ or ┬ shaped profile of the jet-forming mesh, while the inner surface of the housing is made with installation grooves for placement in the last protrusions, which is equipped with a horizontal section of the jet-forming mesh, and bevel for ease of replacement of the latter [3].

A disadvantage of the known device selected as a prototype is the difficulty associated with replacing the jet forming mesh, caused, as a rule, by the need to use additional mechanical means (screwdrivers, scissors, knife blades, etc.) to remove it from the shower head body using bevel in the latter, which, in turn, increases the replacement time and can lead to damage to the housing and mesh made of polymeric materials.

A new technical result is to increase the convenience and reduce the time to replace jet forming nets, as well as increase the reliability of the main parts of the shower head.

This is achieved by the fact that in a shower head containing a pipe for supplying water, a sealing ring, a housing, a nut connected to it by a thread and stream forming nets with nozzle openings of a conoidal profile, ACCORDING TO THE INVENTION, a through nut and stream forming mesh with an appropriate number of nozzle openings are made in the form injection by single-factor to be connected directly or through a threaded sealing ring to the housing of the showerhead, wherein the number of species (K _i.) obtained after konstruktivov manner, depending on the number of nozzle openings in the jet forming ssotvetstvuyuschey grid is determined from the relationship:

1≤K _i ≤4, where i = 1, 2, 3, 4,

wherein: 1≤K ₁ ≤10 10 <K ₂ ≤30 30 <K ₃ ≤50 50 <K ₄ ≤70.

At the same time, the o-ring is placed in the corresponding groove located on the outer surface of the corresponding end portion of the body of the shower head.

A threaded connection of the nut structure with the jet-forming mesh and the body of the shower head is carried out either on the external or internal surface of the latter.

The distance (in mm) between the centers of the outlet openings in the corresponding jet-forming mesh (A) is determined from the condition:

5≤Δ≤15

определяется из соотношения:In this case, the value of the outlet diameter of the nozzle hole in the jet forming grid

determined from the ratio:

Moreover, the body, the structural element of the through nut with the jet forming mesh is made by injection molding of thermoplastic materials, which are used as polystyrene, ABC-plastic, polypropylene, polycarbonate, etc.

In addition, a tapered thread or bayonet connection is used to articulate the nut construct with the jet forming mesh with the body of the shower head.

The use of a range of straight nuts with strain-forming grids with a different number and / or type of nozzle holes made in a single design allows you to adapt the shower head to different quantitative characteristics of the pressure system used and / or requirements for the type and intensity of hydromassage procedures while ensuring convenience and reducing the time of replacement of jet-forming grids and improving the reliability of the main parts of the shower head.

Thus, the claimed method meets the criteria of the invention of "novelty."

Comparison of the claimed solution not only with the prototype, but also with other technical solutions in the art showed that a shower head is known comprising a body made of polymer material with a side hole and a bottom part with a jet forming mesh with cylindrical profile holes, threaded to the body, as well as a water supply pipe and a reflective element mounted on the body in the form of a tide or washer [4].

However, the use of cylindrical profile holes in the jet head of the shower head of this device also does not provide the maximum kinetic energy of the jets [2], which, in turn, does not allow to achieve the maximum effect of hydromassage procedures in terms of achieving the corresponding water acupuncture effect due to the lack of the possibility of obtaining maximum hydrodynamic pressure of the jets on the surface to be treated (µ = φ = 0.82).

In addition, the design of this device uses one jet-forming mesh with a constant number of nozzle openings, which can be a negative factor affecting the quality and effectiveness of hydromassage procedures, taking into account the different flow characteristics of mixer taps in specific conditions of different bathrooms and various parameters of the hydrodynamic pressure of the jets on the treated surface, required for massage of various parts of the human body.

This allows us to conclude that the claimed technical solution meets the criterion of "significant differences".

1 is obtained by molding a suitable thermoplastic material (such as polystyrene) under pressure into the mold shower head, as seen from the jet forming grid at n ^Pp. = 61.

In Fig.2 presents a shower head in Fig.1, a side view with a vertical position of the shower head, section.

The shower head contains, for example, a housing 1 made of polymeric material, a nut 2 connected to it with its thread forming nets (not shown in Fig. 1,2) with nozzle openings 3 of a conoidal profile and, for example, a submillimeter output section.

In this case, the installation of the selected construct, including the nut 2 with the jet-forming mesh in the housing 1 is carried out by means of a threaded connection (including a conical type) through an o-ring 4 made of an elastic material located in a groove (not designated in Fig. 2) located (in in this case) on the outer surface of the corresponding end portion of the body 1 of the shower head.

The proposed shower head operates as follows.

First, the actual specific water flow rate is determined (empirically) with the temperature required for the procedure (usually not higher than 30-40 ° C) per one jet forming grid in a specific household bath.

в соответствующем конструктиве, определяют, в соответствие с количеством видов (K_i) последних, из соотношений (при Р=0,2 МПа):At the same time, the specific flow rate of water (l / s) required for hydromassage procedures with an acupuncture effect coming from its source and falling on one jet-forming net

in the corresponding construct, determine, in accordance with the number of species (K _i ) of the latter, from the ratios (at P = 0.2 MPa):

according to the actual value of which, for a particular bathtub, the number of outlet openings in the corresponding jet-forming mesh is selected, in accordance with which the nut 2 is screwed with the corresponding jet-forming mesh with the housing 1 through an o-ring 4 made of an elastic material located (in this case) on the outer surface of the corresponding end portion of the housing 1 of the shower head.

Closing the curtain screen (to prevent water splashes outside the volume of the household bathtub) and adjusting, using the corresponding valves of the mixer tap (shown in Fig. 1), the flow rate and the required temperature of the water used for hydromassage, the shower head is prepared for hydromassage procedures .

In this case, unlike the prototype, to replace the jet-forming mesh does not require the use of additional mechanical means (screwdrivers, scissors, knife blades, etc.) to remove the mesh from the body of the shower head, using a bevel in the latter, which, in turn, increases convenience and reduces the time of replacement of jet-forming nets and does not damage the casing and mesh made of polymeric materials.

Thus, the proposed shower head for carrying out hydromassage procedures in a household bath, in comparison with the one selected as a prototype, is distinguished by a more convenient and quick replacement of jet forming nets, as well as increased reliability of the main parts of the shower head.

The implementation of the proposed device does not meet fundamental difficulties.

So, constructs including nuts with jet-forming nets with a nozzle hole structure formed, for example, in accordance with RF patent No. 2296672, can be manufactured using appropriate thermoplastic material, molds and equipment, for example, an ARBURG type injection molding machine - A 270-21-500 .

And as a thermoplastic material for hydromassage panels, you can use polystyrene, ABC - plastic, polypropylene or acrylic.

A comparison of the technical characteristics and functionality of the claimed shower head for hydromassage procedures with the prototype, as well as domestic and foreign devices of a similar purpose, shows that the use of a range of straight nuts with jet forming nets with a different number and / or type of nozzle holes made in a single design allows you to adapt shower head for various quantitative characteristics of the pressure system used and / or requirements for type and in intensities of hydromassage procedures while ensuring convenience and reducing the time of replacement of jet forming nets and increasing the reliability of the main parts of the shower head, which indicate the guaranteed achievement of a new technical result in bathrooms with various quantitative parameters of pressure systems and the requirements for the intensity and type of hydromassage procedures being implemented.
