Abstract

A showerhead comprises a body with a handle containing a tube for supplying water to the showerhead, wherein the body contains one or more chambers and wherein, in at least one of said chambers, water outlet openings are arranged at such angles to the plane of the outer surface of the showerhead and in such a pattern on the plane of the outer surface of the showerhead and have such a diameter that the jets of water exiting the showerhead are simultaneously directed toward at least one region of the user's face without getting into the user's eyes, nose and mouth. A method of hydromassaging the face involves acting simultaneously and symmetrically on specific regions of the skin of the user's face, along massage lines, using upwardly angled jets of water at a pressure of about 1.5-2 atmospheres.

Description

SHOWER WITH HYDROMASSAGE OF THE FACE AND METHOD OF HYDROMASSAGE OF THE FACE

The invention relates in general to the field of sanitary and hygienic equipment, and in particular to a shower head (shower head), made with the possibility of implementing a hydromassage mode.

In 1861, the German anatomist Karl Langer published his work On the Anatomy and Physiology of the Skin. On the splitting of the skin. In it, he was the first to define the elasticity of the skin and described the presence of conditionally drawn lines on the surface of the skin, along which it is most extensible. These conditional lines later became known in medicine and cosmetology as Langer lines.

In modern medicine and cosmetology, an important task is to preserve and increase the elasticity of human skin, which gives significant positive cosmetic and aesthetic effects, and is especially important for facial skin. Among the means aimed at maintaining and increasing the elasticity of facial skin, facial massage is of paramount importance, which is one of the most common and important procedures in the field of medicine, cosmetology and daily body care. There is a wide range of means and methods for performing facial massage, which are subject to a number of serious requirements. In particular, with any type of facial massage, it is strongly recommended to adhere to the massage lines mentioned above (Langer lines). In addition, massage movements during facial massage must be strictly symmetrical, since all facial massage techniques must be consistent with the anatomical location of the muscles and lymphatic vessels that flow in both directions from the midline of the face.

It is extremely difficult for the user to perform an independent facial massage, since, as indicated above, serious requirements are imposed on facial massage, non-compliance with which can bring not benefit, but harm. The use of hydromassage techniques greatly facilitates the task of performing an independent facial massage. However, the hydromassage means known from the prior art are of little use for performing a facial massage in accordance with all the requirements for it.

So, for example, as a hydromassage means, a shower nozzle "Alekseev's shower" is known (see, for example, patent of the Russian Federation No. areas of the human body. This effect is realized due to the fact that in the shower head each of the jet-forming grids is made in the form of a set of individual jet-forming nozzles of the corresponding outlet diameter, thus reducing the thickness of the water jets emerging from the nozzle, as a result of which, among other things, the water pressure increases by 3-5 once.

The significant disadvantages of this well-known solution in relation to facial hydromassage include the lack of the possibility of a simultaneous direction of water jets emerging from the shower head at an angle other than direct, simultaneous exposure to strictly certain areas of the face surface. Essentially, this analogue solves the problem of achieving the maximum water acupuncture effect from hydromassage procedures by obtaining the maximum possible hydrodynamic pressure of the jets on the treated surface (µ=φ=0.82). However, this solution is not suitable for facial hydromassage due, firstly, to the impossibility of a simultaneous symmetrical effect on the left and right halves of the face with equal jet strength, not to mention the massage along the above massage lines, and secondly, due to the inevitable hit massage jets into the eyes, nose and mouth, which is uncomfortable for the user, and thirdly, due to the high probability of undesirable effects (up to a traumatic effect on the skin of the face) under the action of the force of the water jet, which is excessive and traumatic for sensitive facial skin .

The technical problem solved by the present invention is to provide a means for optimal one-time hydromassage of the face along massage lines (consistent with the anatomical location of the muscles and efferent lymphatic vessels that are directed to both sides of the midline of the face) using water jets, which eliminates the disadvantages of the described above the state of the art.

The problem solved by the invention is to create a shower head with a mode for hydromassage of the face and a method for hydromassage of the face, implemented by the mentioned shower head, in which the hydromassage of the face is carried out along the massage lines (anatomically) by simultaneously hitting water jets symmetrically with equal force on the left and right half from bottom to top, at an angle other than straight, with the exclusion of water jets from entering the eyes, nose and mouth of the user.

The technical result achieved by using the invention is to provide an optimal one-time symmetrical massage effect on certain areas of the face while excluding hydromassage jets from entering unwanted areas. In particular, the effect is provided, which consists in providing an optimal one-time symmetrical massage effect with water jets at a certain angle on certain areas of the face (along massage lines (Langer lines) according to the anatomical location of the muscles and draining lymphatic vessels). The result is a noticeable positive effect on skin elasticity. It also excludes the possibility of a traumatic effect on sensitive facial skin due to the effect of hydromassage jets, which are optimal in strength and direction.

To solve the above problem, in the first aspect, the invention relates to a shower head containing a body, with a handle, inside which there is a channel for supplying water to the shower head, and inside the body there are one or more cavities communicating with the water supply channel and adjoining outlets for water in the outer surface of the shower head, moreover, in at least one cavity, the water outlets are located at such angles to the plane of the outer surface of the shower head and have such a diameter that the water jets emerging from the shower head at a pressure of about 1.5-2 atmosphere are directed to at least one zone of the user's face symmetrically relative to the user's face, along the massage lines, while excluding water jets from entering the user's eyes, nose and mouth.

In one or more embodiments of the invention, at least part of the water outlets of at least one cavity are located at angles to the plane of the outer surface of the shower head, other than a right angle. In one or more embodiments of the invention, at least a portion of the water outlets of at least one cavity has an inlet diameter different from the outlet diameter. In one or more embodiments, the water outlet diameters are in the range of approximately 0.6 to 1.5 mm for one or more groups of water outlets corresponding to the user's cheek region, and in the range of approximately 0.5 to 1.5 mm for one or more groups of water outlets corresponding to the user's forehead area. The angles between the axes of the water outlets are in the following ranges: α _max - approximately from 6° to 64°, β1 _min - approximately from 2° to 44°, β1 _max - approximately from 4° to 51°, β2 _min - approximately from 2° to 58°, β2 _max - approximately from 3° to 63°, where α _max is the range of jet divergence angles in the vertical plane, β1 _min and β1 _max are the largest and smallest angles between the extreme inner and outer outlets from the right and the left side for the forehead area of the user, and β2 _min and β2 _max are the largest and smallest angles between the extreme inner and outer outlets on the right and left side for the cheek area of the user. In one or more embodiments of the invention, water outlets are placed on the plane of the outer surface of the shower head in one or more groups in accordance with the location of the massage zones on the user's face. In one or more embodiments, the shower head is provided with a switch configured to switch the operating modes of the shower head between normal mode and hydromassage mode, wherein at least one of said one or more cavities corresponds to one or more groups of outlets that implement the normal mode and /or hydromassage mode. In one or more embodiments, in all other cavities, except for said at least one cavity, the water outlets are evenly spaced and configured to allow the shower head to operate normally.

In a second aspect, the present invention relates to a method of hydromassage of the face, carried out using a shower head according to the first aspect of the present invention, and the method comprises the step of exposing areas of the skin of the face with jets of water at a pressure of about 1.5-2 atmospheres directed at an angle , other than a right angle, along the massage lines, and the mentioned areas of the facial skin are located symmetrically in the forehead, cheeks and cheekbones, around the nose and eyes of the user. In one or more embodiments, the water has a temperature of about 34-36° C. or 37-39° C. In one or more embodiments, the water jets also act on the chin and skin of the front of the neck of the user. In one or more embodiments of the invention, water jets are directed at the user's face from a distance of approximately 130 mm. The duration of exposure of the water jets to the user's face can be approximately 3-5 minutes. The impact of water jets is one-time and directed along the lines passing from bottom to top and to the outer contour of the face in the area of the forehead, cheeks and cheekbones of the user, to the bridge of the nose under the eyes of the user and to the outer contour of the face above the eyes of the user, from bottom to top around the nose of the user.

Facial massage is one of the most common and important procedures in the field of medicine, cosmetology and daily body care. There is a wide range of means and techniques for performing facial massage, but performing this procedure on your own is not an easy task and is allowed only if it is performed in accordance with the requirements for facial massage techniques described below. General techniques of facial massage should be consistent with the anatomical location of the muscles and efferent lymphatic vessels, which are sent to both sides of the midline of the face.

In general, the requirements for facial massage are as follows:

1) The impact should be carried out strictly along the massage lines of the face, also called Langer lines (see, for example, https://sadykova.live/kultura-langer-lines).

2) Massage movements during facial massage should be strictly symmetrical (see, for example, Basics of classical massage: teaching aid: 2nd edition, revised and supplemented / V. M. Ogryzkov, S. V. Salko - Omsk: BU DPO OO TsPK RH, 2018 - 88 p., p. 64).

3) When performing a facial massage using hydromassage, water jets should not enter the user's eyes, nose and mouth.

Thus, it is very difficult to do a facial massage with your fingers and do no harm - there is a high risk of improper distribution of efforts along the massage lines. In this regard, hydromassage has significant advantages - a method that combines the unique qualities of water, the combined effect of water jets and massage techniques, which eliminates the risk of improper distribution of efforts and greatly simplifies the independent procedure if a concentrated hydromassage effect is on the desired areas (zones) of the face.

Hydromassage using a shower equipped with a specialized shower head is known, for example, from the above prototype of the present invention. In the general case, the water leaving the nozzle of a specialized shower head is a drop-like stream capable of being under the right pressure, at the right temperature, etc. act on one or more key points on the user's body, including the face, with the achievement of various therapeutic, cosmetic and physiotherapeutic effects, as well as to improve the general physical and psycho-emotional state of the user.

In this regard, there are many different specialized showers and devices for conventional household hygienic showers, designed to provide hydromassage to various parts of the user's body. However, they (see, for example, the closest analogue of the present invention described above) are not well suited for massaging the user's face, especially for optimal massage effects on certain areas of the user's face. In particular, this is due to the fact that in the known means of hydromassage using a shower, a one-time and symmetrical effect of massage jets on the left and right half of the face and at a certain angle is not ensured, and thus the ingress of water into the eyes, nose and mouth of the user is not excluded, which makes hydromassage of the face uncomfortable and difficult for the user, forcing him to periodically interrupt the procedure to catch his breath, etc.

In accordance with the present invention, there is provided a shower head, shown schematically in FIG. 1. It contains a body 1 with a handle 2, inside which there is a channel for supplying water to the shower head, and inside the body there are one or

more cavities

3, 5 communicating with the channel for water supply and adjoining

outlets

4, 6 for water in external (working) surface of the shower head. In at least one cavity 5, outlets 6 are located at such angles to the plane of the outer surface of the shower head and with such placement on the plane of the outer surface of the shower head, and have such a diameter that the water jets emerging from the shower head are directed at least into one zone of the user's face, symmetrically falling into at least two massage zones on the left and right sides of the face, while excluding the ingress of water jets into the eyes, nose and mouth of the user. Essentially, in one or more embodiments of the invention, the shower head according to the invention is similar to a conventional household head with several modes, however, it differs in that it implements an operating mode in which there are one or more groups of outlets placed in a certain way on the plane of the outer surface of the shower head. 4, 6 with different diameters and directed at certain angles so that the jets hit only the desired areas on the user's face and do not hit, in particular, the user's eyes, nose and mouth. In particular, in a preferred embodiment of the invention, a one-time massage effect is thus realized at a certain angle on four zones on the user's face - two zones symmetrically on the forehead above the eyebrows and two symmetrically on the user's cheeks (see Fig. 4).

As shown in FIG. 1, the shower head according to the invention comprises one or more (preferably at least four)

cavities

3, 5 communicating with the water supply pipe and adjoining

outlets

4, 6 in the outer surface of the shower head. In this case, the cavities 3 can be used to provide the usual household hygienic mode of operation of the shower head, and the cavities 5 can be used to provide the hydromassage mode in accordance with the invention. The outlets 4 may be formed in the outer surface of the shower head and positioned in such a way as to implement the normal household hygienic operation of the shower head, for example, they may be uniformly distributed on the plane of the outer surface of the shower head and may extend substantially at right angles to the plane of the outer surface of the shower head.

At the same time, the outlets 6, as shown in FIG. 1 may correspond to the cavities 5 and may in particular be formed at an angle other than a right angle with respect to the plane of the outer surface of the shower head. In addition, at least part of the hydromassage outlets 6 for at least one cavity 5 has an inlet diameter (that is, a diameter on the side facing the cavity 5) different from the outlet diameter (that is, from the diameter on the side facing the cavity 5). facing the outer surface of the shower head). In particular, the inlet diameter may be smaller or greater than the outlet diameter, depending on the particular embodiment of the invention.

Referring to FIG. 6-8, a non-limiting specific embodiment of the shower head according to the invention will now be described in terms of the execution of outlet openings 6 realizing the hydromassage mode in at least one cavity 5, and in particular their diameter, shape, as well as the angles between the axes of the outlet openings. 6.

In at least one embodiment of the invention, the shape of the outlet 6 on the side facing the cavity 5 is formed by the intersection of a cone and a plane at an angle to the cone, that is, essentially an ellipse. Moreover, the elongation and size of the ellipse differs for different outlet holes 6 in different groups of outlet holes 6 from an almost circle with a diameter of 1.9 mm in one or more groups of outlet holes 6 corresponding to the user's chin area to an elongated ellipse with axes of 2 mm and 2, 4 mm in one or more groups of outlets 6 corresponding to the user's forehead area. It should be understood, however, that the above specific sizes and shapes of outlets 6 do not limit the scope of the present invention, and other possible shapes of outlets 6 may be apparent to those skilled in the art. In addition, in some non-limiting embodiments, a protrusion or recess can be made within the cavity so that the shape of the outlet 6 from the side facing the cavity 5 becomes round and the thin channel for the passage of water becomes shorter. Such embodiments may be advantageous from the point of view of simplifying the manufacture and maintenance of the shower head mold according to the invention.

In one or more non-limiting embodiments of the invention, the diameters of the outlets 6 on the outer surface of the shower head can be, as a non-limiting example, 0.8 - 0.9 mm for groups of outlets 6 corresponding to the user's forehead, and 0.9 - 1 .0 mm for the groups of outlets 6 corresponding to the user's cheek areas (in other words, the outlets 6 for the groups corresponding to the user's cheeks are 0.1 mm larger than those for the groups corresponding to the user's forehead).

In general, the diameters of the outlets 6 on the surface of the shower head according to the invention, facing the face of the user, are in the range of approximately 0.6 ... 1.5 mm for one or more groups of outlets 6 corresponding to the region of the user's cheeks, and approximately 0. 5 ... 1.5 mm for one or more groups of outlets 6 corresponding to the forehead area of the user. The diameter difference between the outlets 6 in the groups corresponding to the user's cheek area and those corresponding to the forehead area of the user is approximately 0.1 to 0.5 mm (the outlets 6 in one or more groups of holes corresponding to the user's forehead area have smaller diameter).

In at least one preferred embodiment of the invention, the diameters of the outlets 6 on the surface of the shower head according to the invention, facing the face of the user, are in the range of approximately 0.8 ... 1.2 mm for one or more groups of outlets 6 corresponding to the region of the user's cheeks. , and approximately 0.7 ... 1.0 mm for one or more groups of outlets 6 corresponding to the user's forehead area. The diameter difference between the outlets 6 in the groups corresponding to the cheek area of the user and the groups corresponding to the forehead area of the user is approximately 0.1 to 0.3 mm.

It should be noted that in one or more embodiments of the invention, one or more groups of outlets 6 may be provided with outlets 6 having different diameters within one group of outlets 6.

The angles between the axes of the outlets 6 projected onto the planes of the respective regions of the user's face are illustrated in FIG. 6-8, and are in the following ranges:

α _max - approximately from 6° to 64°,

β1 _min - approximately from 2° to 44°,

β1 _max - approximately from 4° to 51°,

β2 _min - approximately from 2° to 58°,

β2 _max - approximately from 3° to 63°,

where α _max is the range of jet divergence angles in the vertical plane, β1 _max is the largest and smallest angles between the extreme inner and outer outlets on the right and left sides for the forehead area of the user, and β2 _min and β2 _max are the largest and smallest angles between the outermost inner and external outlets on the right and left side for the user's cheek area.

The calculated values of the angles of divergence of the jets at the outlet of the outlet holes of the massage head for three possible options for the operating position of the handgun according to the invention relative to the user's face at the above angles between the axes of the outlet holes 6 are shown in Table 1 below.

It should be noted that, as indicated in the above Table 1, the working distance (in other words, the optimal distance in terms of the hydromassage effect of the water jets from the shower head according to the invention on all relevant areas of the user's face) between the surface of the shower head and the surface of the user's face is at least in one preferred embodiment of the invention approximately L=130 mm.

This operating distance has been derived from the practical implementation of the hydromassage shower head according to the invention, based on the pressure, volume flow, etc. characteristic of tap water entering the shower head from a typical municipal water supply, and using the embodiment described above. parameters of the diameters and angles of outlet holes 6 (as a non-limiting example, with a diameter of 0.8 - 0.9 mm for groups of outlet holes 6 corresponding to the user's forehead, and 0.9 - 1.0 mm for groups of outlet holes 6, corresponding areas of the user's cheeks). As a result, the shower head, implemented in accordance with the above parameters, provided simultaneous and symmetrical impact on the skin areas of the face located in the area of the cheeks and forehead of the user, with water jets under pressure of about 1.5-2 atmospheres, directed at an angle from bottom to top, while water jets practically did not fall into the area of the eyes, nose and mouth of the user (as shown, for example, in Fig. 2).

In one or more embodiments of the invention, the outlet holes 6 can be distributed on the plane of the outer surface of the shower head in such a way that they form one or more groups of holes, the location of which corresponds to the massage zones of the user's face, which should be hit by water jets in hydromassage mode. In the preferred embodiment, as shown in FIG. 1, outlet holes 6 are grouped into four groups located near the center of the outer surface of the shower head, with two of the four groups of holes 6 located in two concentric arcs in the second and third quarters of the corresponding surface of the shower head having a round shape, and the other two of the four groups of holes 6 are arranged in two concentric arcs in the fourth and first quarters of the respective surface of the round shower head, the first said two groups having more holes than the second said two groups. It should be understood, however, that such an arrangement of groups of holes on the outer surface of the shower head is only one specific non-limiting example, and many other configurations of water outlets 6 for water, taking into account round or other (for example, square) shape the outer surface of the shower head. In general, the outlets 6 may be arranged in two or more groups according to the location of the desired massage areas on the user's face.

It should be noted that the outer surface of the shower head, in which there are outlets 6 providing jets of water to implement the hydromassage mode, and which is also referred to in the present description as a work surface, in one or more non-limiting embodiments, may also contain outlets 4 that implement the usual operating mode of the shower head. However, the present invention is not limited to this, and in some non-limiting embodiments, the outlets 6, which implement the hydromassage mode of the face, and the outlets 4, realizing the normal mode of operation of the shower head, can be made in different external surfaces of the shower head, for example, from two opposite sides when double-sided shower head configuration. In this case, when switching between the normal mode of the shower head and the hydromassage mode, different surfaces of the shower head will be used. In addition to opposite sides, other possible shower head configurations may be apparent to those skilled in the art in which the outlets for the normal mode and the whirlpool mode are provided in different surfaces of the shower head. It should also be borne in mind that the scope of the present invention also includes embodiments in which the shower head implements only the hydromassage mode and, accordingly, has only cavities 5 and outlets 6 designed to implement this mode.

The configuration of the groups of outlets 6, as well as the angles at which the outlets 6 pass relative to the plane of the outer surface of the shower head, ensure that the water jets coming out of the shower head from the bottom upwards in relation to the user's face simultaneously and symmetrically, strictly into certain areas on the user's face along massage lines (Langer lines). This keeps the water jets out of the user's eyes, nose and mouth, allowing the user to breathe freely during the entire procedure and relieves the discomfort caused by water entering the nose and eyes.

As mentioned above, in one or more non-limiting embodiments, the shower head is configured to switch between the normal domestic (hygienic) mode and the whirlpool mode described above. In various embodiments, switching modes can be done using a button or lever placed on the shower head or water supply hose, or by turning the outer surface of the shower head, tilting and / or turning the shower head or its components, and the like. Those skilled in the art will appreciate many other options for changing shower head modes, and the specific options for switching modes do not limit the scope of protection of the present invention.

To implement the hydromassage mode, tap water is used, supplied under normal pressure and pressure, which is characteristic, in particular, for city water supply. At the same time, the showerhead according to the invention provides, in the hydromassage mode, the ingress of water onto the massage zones of the user's face under a pressure of about 1.5–2 atmospheres, which is sufficient to provide an effective massage effect, while excluding traumatic effects on the tissues of the user's face.

However, it should be understood that the scope of legal protection of the invention is not limited to the above-described specific parameters of the diameters and angles of the outlet holes 6 for water, as well as parameters of pressure, volume flow, and the like. tap water entering the showerhead inlet. The parameters of the angles of the outlet holes 6, their diameters at the inlet and outlet, the shape of their section, etc. in terms of jet divergence, taking into account the specific parameters of the water flow at the inlet to the shower head, can be calculated for other embodiments of the present invention based on a mathematical model of the movement of the liquid jet at the exit from the outlets 6 of the shower head.

The shower head according to the invention can be made from materials used for the production of shower heads for domestic hygienic showers. As a non-limiting example, a shower head, and in particular its body, handle, and other components, can be injection molded from various thermoplastic materials used in the art, such as polystyrene, ABS plastic, polypropylene, polycarbonate, and the like. . The scope of legal protection is not limited to the method of manufacture, the choice of specific materials and / or their specific parameters.

Next, the facial hydromassage method according to the second aspect of the present invention will be described.

Hydromassage, in particular with the help of a shower, is referred to as a hydrotherapy procedure (section of hydrotherapy), based on the effect on the skin of the body with water jets of various shapes, a certain temperature and pressure.

According to the shape and direction of the water jets, as well as the intensity of the mechanical impact, the hydromassage regimen of the face in accordance with the invention can be attributed to the combined type of massage - needle-rain (see, for example, Belovol A.N., Tkachenko S.G., Tatuzyan E. G. Physiotherapy in cosmetology: textbook for an elective course. - Kharkiv: KhNMU, 2015 - 132 pp., pp. 75, 80).

In general, the method of hydromassage of the face in accordance with the invention consists in exposing the areas of the face located, as a non-limiting example, in the forehead, cheeks and cheekbones, around nose and eyes of the user. Certain massage lines are coordinated with the anatomical location of the muscles and efferent lymphatic vessels, which are directed to both sides of the midline of the face. Preferably, water jets directed at an angle from bottom to top with respect to the user's face act on the user's face at a pressure of about 1.5-2 atmospheres, which is an average degree of water pressure sufficient to provide a massage effect, but not causing a traumatic effect on the skin and facial tissue of the user.

More specifically, at the moment of pointing the shower head in the hydromassage mode on the user's face, water jets of a given diameter at a certain angle simultaneously and symmetrically affect skin areas strictly in the directions of the muscle fibers of the face and along the given massage lines (see, for example, Fig. 2, 3 , 5). The user must hold the shower head at a comfortable distance from the face (about 100 - 300 mm). This prevents the water jets from entering the eyes, nose and mouth as with normal shower use, allowing the user to breathe freely throughout the facial hydromassage treatment without interrupting the treatment. The duration of the facial hydromassage procedure using a shower head according to the invention is, as a non-limiting example, about 3-5 minutes, however, it should be understood that the scope of the invention is not limited to this specific duration, and in other particular embodiments of the invention, the duration of the facial hydromassage procedure may be longer or less time. The specific time of the hydromassage effect on the face can be determined by the user, based on their own physiological characteristics.

As shown in FIG. 5, the impact of water jets in accordance with the method according to the invention is generally directed along the massage lines (in other words, Langer lines) passing from the bottom up and to the outer contour of the face in the forehead, cheeks and cheekbones of the user, to the bridge of the nose under the user's eyes and to the outer the contour of the face above the user's eyes, from bottom to top around the user's nose. Massage lines are directed mainly from the center to the periphery: from the middle of the chin - to the earlobes, from the middle of the upper lip and the outer corner of the eye - to the tragus of the auricles; from the middle of the forehead - to the temporal cavities.

Facial massage lines, or Langer lines, are the directions in which the skin is stretched the most. That is, by doing a massage along these lines, you can be sure that it will not deform or sag. Science has long known about the existence of such a substance as collagen. These are protein filaments present in the connective tissue, namely in the intercellular substance. Collagen provides firmness and elasticity to the fibers. This substance forms peculiar beams.

The layouts of the massage lines, according to which it is recommended to perform facial massage in all cases, are also described in detail, for example, in the source Kashutin S.L. Dermatocosmetology: textbook / S.L. Kashutin, Ya.V. Gilmutdinov. - Arkhangelsk: Publishing House of the Northern State Medical University, 2015. - 122 p.; ISBN 978-5-91702-216-1 (see pp. 28-29).

In one or more embodiments, the water during the hydromassage of the face may have a temperature in the ranges of about 34-36°C (indifferent) or 37-39°C (warm). However, it should be borne in mind that these temperature ranges are only preferred and do not limit the scope of legal protection of the invention. As such, depending on the specific modes recommended to the user and/or the individual preferences of the user, colder or hotter water may also be used in facial hydromassage. Furthermore, in addition to the above-described regions of the user's face, the massage effect may also be applied to the user's chin and the skin of the front of the neck of the user. As a non-limiting addition, as will be apparent to those skilled in the art, hydromassage of other parts of the user's body, such as, for example, the chest, is also possible with the showerhead according to the invention.

In general, when performing hydromassage of the face, it is sufficient for the user to hold the shower head according to the invention still, and this is sufficient to achieve the desired hydromassage effect on the corresponding areas of the user's face. However, in at least some non-limiting embodiments of the invention, in particular, taking into account the anatomical features of the face of a particular user, it may be possible to perform hydromassage with small movements of the shower head, which allows, if necessary, to increase the zone of massage exposure (expand the zones of massage on the face), while it also ensures that the hydromassage jets hit the desired areas at the same time and that water does not enter the user's mouth, eyes and nose.

The possibility of achieving the above technical result and realizing the purpose of the invention was experimentally verified in the course of a study in which a three-dimensional scanning of the heads of 122 potential users with various face shapes was carried out, on the basis of which three-dimensional models of the users' heads were created. On each of the models obtained, the areas subject to hydromassage exposure were indicated in accordance with the method of hydromassage of the face according to the invention. In the course of analyzing the differences in the sizes of these zones, it turned out that with at least one of the configurations of the angles of inclination, diameters and the number of outlets 6 in a shower head with a hydromassage mode that implements the hydromassage method according to the invention, there can be an optimal one-time effect of water jets on the corresponding massage zones of all examined persons with a relatively small (up to 20 mm distance from the face and up to 10° turn in the vertical plane) adjustment of the position of the shower head for the preferred embodiment of the invention.

In addition, similar experimental studies confirming the possibility of achieving a technical result and realizing the purpose with the implementation of the present invention were carried out based on the parameters of the faces of various user groups presented in the anthropometric data set published in the US National Institute for Occupational Safety and Health (NIOSH Dataset RD-10130- 2020-0). In the published data set, 5 types of face shapes are distinguished depending on their sizes, as well as the distances between the zones on the face, which correspond to the massage zones, which are affected by water jets in accordance with the present invention. It has been shown that for all 5 types of face shapes presented in the published dataset, the distance from the face to the shower head and the angles of divergence of the jets will be in the ranges indicated above in Table 1, with the above ranges of angles between the axes of the outlets and the diameters of the outlets in the respective outlet groups of the shower head according to the invention.

On FIG. 9 illustrates the test result of a prototype shower head according to one exemplary embodiment of the invention. Tests have shown that a shower head made with one working cavity, containing 4 groups of outlets located on an annular platform between diameters of 38 and 54 mm on the working surface of the shower head, ensured that water jets hit simultaneously and symmetrically into four massage zones of the user's face (two in the user's cheeks and two in the user's forehead) strictly along the massage lines, with a certain inclination from bottom to top under a pressure of 1.9-2 atm. In the respective groups, outlets were located at angles α _max = 28°53`, β1 _min = 14°35`, β1 _max = 18°32`, β2 _min = 17°24`, β2 _max = 22°11`, while The exit holes had a diameter of 0.8 mm for the hole groups corresponding to the user's forehead area and a diameter of 0.9 mm for the hole groups corresponding to the user's cheek area. At the same time, as seen in Fig. 9, the massage jets of water fell strictly into the corresponding massage zones of the user's face, acting symmetrically on them, and did not fall into the eyes, nose and mouth of the user, which confirms the implementation of the shower head according to the invention of the facial hydromassage mode that meets the above requirements for facial massage, and the achievement technical result, which consists in providing an optimal one-time symmetrical massage effect on certain areas of the face while excluding the ingress of hydromassage jets on unwanted areas.

The method of facial hydromassage according to the invention includes several mechanisms of action on the body at once:

a) massage effect: water jets activate blood and lymph flow, promote the removal of metabolic products from tissues, increase tissue elasticity and skin tone;

b) temperature effect: water during hydromassage can be cool, "neutral" temperature, or warm - depending on this, either tonic and immunostimulating, or relaxing, antispasmodic and calming effect will prevail;

c) reflexogenic effect: acting on biologically active points, water jets cause a complex of reactions from the autonomic nervous system and thereby stimulate the work of internal organs.
