The invention relates to sanitation devices, namely, to showers head sanitary soul and is intended for use mainly in the household tanks and physical therapy offices, clinics, hospitals and spas, for purposes of Spa procedures and obtain different water effect on different areas of the body.
Known shower head containing the case with is located the running camera and connected with housing grid with holes conical profile, and the casing is fitted with a partition, and flow camera is equipped with a freely moving spherical body with a diameter of not less than the inner diameter of the outlet openings grid [1].
The disadvantage of this device is the lack of possibility of replacement of grid, which can be called as a clogged nozzle holes and coordination of expenditure characteristics of the pressure system with high-speed pressure generated shower head jets, necessary for carrying out of Spa procedures and receive relevant water effect.
In addition, using the grids shower heads holes conical profile does not allow to ensure the maximum kinetic energy of the jets [2], which, in turn, does not allow to achieve maximum effect from the Spa procedures in the achievement of the relevant water effect due to lack of opportunity of obtaining the maximum hydrodynamic pressure jets on a processed surface.
Closest to the claimed technical substance and the result achieved known solution, chosen as a prototype, is the shower head containing made from polymer materials pipe for water supply, housing, connected with him carvings checkpoint nut and fixed it has to be installed inside the case of two types nets made with ┼ or nitrosamines shaped profile, vertical part of which is made with solid, including spherical use for placing of 19 or 61 nozzle holes - profile and output diameters submillimeter section, and horizontal her plot to place the o-ring made of elastic material, installed on the respective diameter of the bottom of the vertical part of ┼ or nitrosamines shaped profile grid, and the inner surface of the case is made with the alignment notches for placement in the last projections, which are equipped with a horizontal section grid, and bevel for easy replacement of the last [3].
The disadvantage of this device is selected as a prototype, is the difficulties associated with the replacement of grid, caused, as a rule, the necessity of use of additional mechanical means of a screwdriver, scissors, knife blade, etc.) to remove it from the chassis shower head, using the bevel in the latter, which, in turn, increases the replacement and can lead to damage made of polymeric materials and mesh.
New technical result consists in the increase of facilities and reducing the time to replace nets, as well as improving the reliability of the main parts of the shower head.
This is achieved by the fact that in the shower valves containing pipe for water supply, the seal ring, housing, connected with him threaded nut and grid with nozzle orifices profile, ACCORDING to the INVENTION, the checkpoint of the nut and grid with the appropriate number of nozzle holes are in the form of the resulting by the method of single-factor, connecting thread directly or through the o-ring with housing shower head, and the number of species (K i .) received thus constructs, depending on the number of nozzle holes in grid, determined from the relation:
1 < K i < 4; i=1, 2, 3, 4,
when this:
1 < K with 1 < 10
10<K 2 ≤30
30<K 3 is < 50
50<K 4 ≤70.
In this case, the o-ring is placed in the appropriate slot, located on the outer surface of the proper end part of the building of the shower head.
And threaded connection of cabinets nuts with net and housing shower heads performed either by external or internal surface of the latter.
The distance (in mm) between the centers of the vents, appropriate grid (A), determined by condition:
5 Δ≤15
In this case, the value of output diameter of nozzle holes in the grid is determined from the relation:
Moreover, building a constructive lock nuts with mesh is made by a method of moulding thermoplastic materials under pressure, which are used as polystyrene, ABC plastic, polypropylene, polycarbonate etc
In addition, for connection of cabinets nuts with mesh with housing shower head is used tapered thread or bayonet coupling.
Using performed in a single automated gamma anadromous nuts with nets with different number and/or views of nozzle holes allows to adapt the shower head to various quantitative characteristics used pressure system and/or requirements according to the type and intensity of Spa procedures, ensuring convenience and reduce time to replace grids and increase the reliability of the main parts of the shower head.
Thus, the proposed method corresponds to the invention «novelty».
A comparison of the proposed solutions is not only a prototype, but also with other technical solutions in the field of technology showed that known to the shower head, containing made of polymeric material body with side opening and bottom part with grid with holes, a cylindrical profile, connected thread with the shell and tube feeding water and reflective element is fixed to the shell in the form of high tide or washers [4].
However, using in grid shower head of the device holes cylindrical profile does not allow to ensure the maximum kinetic energy of the jets [2], which, in turn, does not allow to achieve maximum effect from the Spa procedures in the achievement of the relevant water effect due to lack of opportunity of obtaining the maximum hydrodynamic pressure jets on the processed surface (µ=?=0,82).
In addition, this device uses one net with a constant number of nozzle holes, which may be a negative factor affecting the quality and efficiency of Spa procedures, taking into account the different discharge characteristics of cranes, mixers, in the specific circumstances of different bathrooms and the various parameters of hydrodynamic pressure jets on the processed surface required for massage of different parts of the human body.
This allows to make the conclusion about conformity of the proposed technical solution to the criterion of «substantial differences».
Figure 1 presents obtained by casting the appropriate thermoplastic material (e.g. polystyrene) under pressure into the mold shower head, view from the side of grid, n P. =61.
Figure 2 presents shower head in figure 1, a side view of the vertical position of the shower head, section.
Shower head contains executed, for example, of a polymeric material, building 1, joined with him threaded nuts 2 with their nets (figure 1,2 are not marked) with nozzle orifices 3 profile and, for example, submillimeter outlet section.
In this case, set the selected linings, including nut 2 with mesh in the building 1 is with threaded connection (including cone type) via the o-ring 4 of elastic material, disposable in the groove (figure 2 )posted (in this case) on the outer surface of the proper end part of the building 1 shower head.
The proposed shower head works as follows.
First define (empirically) magnitude of actual specific consumption of water with the required procedures for temperature (as a rule not above 30 to 40 degrees C)per one grid in a particular household tub.
The conditions necessary for the Spa procedures with effect of specific water consumption (l/s)received from its source and falling on one grid in the corresponding form factor, determine, in accordance with the number of species (K i ) the last of correlations (R=0,2 MPa):
, , , ,the actual value of which the specific baths, pick a number of outlets in the relevant grid, and produce threaded nuts 2 with the corresponding mesh with housing 1 via the o-ring 4 of elastic material, disposable (in this case) on the outer surface of the proper end part of the building 1 shower head.
Closing the curtain screen (to prevent the ingress of water splashes out of the scope of household baths) and adjusting, using the respective valves crane-mixer (figure 1 shows the flow rate and the required temperature of the water used when hydromassage, shower head was prepared for the conduct of Spa procedures.
Thus, unlike the original, to replace grid does not require the use of additional mechanical means of a screwdriver, scissors, knife blade, etc.) to remove the grid from the housing shower head, using the bevel in the latter, which, in turn, increases the convenience and reduces the time of replacement nets and does not damage made of polymeric materials and mesh.
Thus, the proposed shower head for conducting the Spa procedures in the household tub, compared with selected as a prototype, has a more convenient and quick replacement of grids as well as the increased reliability of the main parts of the shower head.
Implementation of the proposed device is not exposed to principal difficulties.
So, constructs, including nuts with nets with the structure of nozzle holes, formed, for example, in accordance with the RF patent №2296672, can be made using the appropriate thermoplastic material, press-molds and equipment, for example Termoplastavtomat type ARBURG - And 270-21-500.
And as a thermoplastic material hydromassage you can use polystyrene, ABC plastic, polypropylene or acrylic.
Comparison of technical characteristics and functional opportunities claimed shower head for the conduct of Spa procedures with the prototype, as well as domestic and foreign devices of similar purpose, shows that the use made into a single automated gamma anadromous nuts with nets with different number and/or views of nozzle holes allows to adapt the shower head to various quantitative characteristics used pressure system and/or requirements according to the type and intensity of Spa procedures, ensuring convenience and saving time replacement nets and improving the reliability of the basic parts of a shower head that indicate guaranteed reached a new technical result in the bathrooms with different quantitative parameters of pressure systems and requirements to the intensity and type of implemented Spa procedures.
