Cleaning and massage device

The innovation relates to a cleaning and massage device for areas of skin that are particularly in need of care, especially areas of the face and neck, with a mounting body j which has a flat face at its front end ₃ into which a nozzle emerges ₃ which is connected to a water hose via a channel in the mounting body is connected to the rear end of the holder body and the nozzle is surrounded by an elastic splash water protection wall on the end face of the holder body.

Through the DT-OS 25 H ~ 5 378 i ^ t a device of the above type has already become known in which the splash water protection wall is made of foam rubber. However, the known device has not been satisfactory for various reasons;

The splash water protection wall made of foam rubber is mainly used to prevent the spray water escaping from the nozzle on you To limit the skin area in order to achieve a cleaning or massage effect there essentially without exposure to splash water. The known device is used for this purpose

the foam rubber protective wall on the skin area to be treated put on. In the process, however, the space between the skin area, which is delimited by the foam rubber protective wall, is filled and the end face of the nozzle holder body quickly with water, so that the water emerging from the nozzle for cleaning and massage of the skin area only through the water cushion can hit the skin through it. Here, the jet emerging from the nozzle is in its effect was greatly weakened. As a result, the desired cleaning and massage effect is low or even at all not available, so that you only have a very limited cleaning and massage device in the known device can speak at the beginning.

In order to avoid the formation of a water cushion between the nozzle outlet and the skin to be treated, can the user can help himself by having the device only very lightly against the skin to be treated so that the water cushion can flow away along the skin. However, this reduces the formation of the water cushion not yet avoided. Only the back pressure that builds up is reduced.

To prevent the water cushion between the nozzle and the areas of skin to be treated from forming, the user must maintain a distance between the foam barrier and the skin. Besides that as the distance between the nozzle and the skin increases, the desired cleansing and massage effect decreases rapidly, then the purpose of the foam rubber protective barrier no longer becomes or no longer fully met to protect the user from splashing water. This is especially true for fluüische Oscillator nozzles, which have proven themselves especially for cleaning and massage of skin and gum areas.

Also repeated ventilation or lifting of the known device from the skin to be treated to the constantly new one

Degradation of the water cushion between the nozzle and the skin is not very satisfactory, since every time the device is lifted off the user's skin is annoyed by splashing water.

To avoid the disadvantages of the known device is has already been proposed to the limited by the foam protective wall space between the to be treated Chewable parts and the face of the nozzle holder body connect a drain hose.

Apart from _three as £ the arrangement of additional "Sclilauches is costly and inconvenient for the user is the hoped through the drain hose effect very satisfactory, as the water cushion that forms between the nozzle and the skin can not be removed quickly enough, because the open The cross-section of the drain hose cannot be chosen to be sufficiently large for this.

Another disadvantage of the known cleaning and massage device also consists in the fact that when the water hose leading to the device is connected to an adapter on the Faucet the desired water temperature for the device without splashing water nuisance for the user is not easy

'The task of the innovation is therefore to provide a cleaning and

and therefore essential in its cleansing and massage effect is more effective. Also intended to be a simple one from splashing water nuisance largely free use must be ensured.

In this way, the aim is above all to be comfortable and pleasant With a great depth effect, a more intensive cleansing of the facial skin of cream, sebum and sebum residues is possible than they have been with facial stools and more special Cleansing milk is achievable.

The object is achieved according to the invention in that the Splash water protection wall from individual in the frontal area of the nozzle holder body fixed bundles of bristles of such diameter and length in such a mutual Distance is that the upper ends of the bristle bundles form a closed elastic bristle wall, however, in each case between adjacent lower ends of the bristle bundles there are gaps of such size that the water emerging from the nozzle without the formation of a blockage in the space between the sides delimited by the bristle wall a main part and the end face of the nozzle holder body can flow away essentially unhindered.

This ensures that there is essentially nothing between the nozzle and the area of skin to be treated Can build up water cushion, which the effect of the jet emerging from the nozzle in its cleaning and massage effect significantly impaired, since a water cushion is formed over the free gaps between the bundles of bristles can flow off immediately and unhindered. The closed bristle wall is in the area of the upper bristle ends a sufficient protective wall against splash water. In addition, the hair tips of the bristle wall grip resiliently into the pore openings of the skin and massage them gently, so that the effect of the out of the nozzle emerging and unchecked by a cushion of water

7703420 09/29/77

this significantly improves wxrd.

It has been shown that only the innovation-based Combination of the protective wall of spray water, which is preferably made up of animal bristles, with one for For cleaning and massage purposes, a particularly inexpensive nozzle with surprisingly good cleaning and massage effects leads that are many times better than those with the aforementioned known device achievable cleaning and massage effects because of the splash wall both unhindered water drainage from the nozzle area and a good spray water protection wall in the particularly splash-intensive zone near the skin surface and also allows a gentle brush massage of the skin to gently open the pores and because the nozzle is not impaired in its effect by a cushion of water in front of it.

The gite cleaning and massage effect is particularly unsurpassed when the individual bristle bundles made of natural bristles, preferably goat bristles, have a diameter of H mm to 8 mm, preferably around 5 mm, and the clear distance between adjacent bristle bundles at their lower ends is 0, 6 mm to 1.0 mm, preferably around 0.8 mm, and the free length of the bristle bundles 10 mm to 15 mm, preferably 12.5 mm.

It is particularly advantageous to arrange the individual bundles of bristles in one row, because then the water between the Gaps at the lower ends of the bristles can flow largely unhindered.

In principle, the most varied of nozzles can be used in conjunction with the spray water protection wall according to the innovation be used., without thereby the scope of the innovation is left. Excellent results are achieved above all with a fluidic oscillator nozzle

- 6 is already used in oral irrigators.

Therefore, a renewal execution in accordance with particularly preferred consists of a single row tufts wreath of goat bristles of about 5 mm in diameter and about 12 ₃ 5 length at a distance of about 0.8 mm * of an end face of a nozzle holder body having an opening formed as fluidisehem oscillator nozzle in the way as it has become known from DT-OS 25 ^ 3 378, the nozzle outlet opening slightly protruding from the front face of the nozzle holder body.

Further advantageous designs and developments of the cleaning and massage device according to the innovation result from the features of additional subclaims and the description below,

Thus, stress-free handling of _{the massage device according to the invention can be achieved 3 in} that the nozzle holder body is provided with a switching device that releases the connection of the nozzle to the water hose by hand against a spring force.

With this changeover device according to the invention also achieve a very sensitive pressure control of the spray jet emitted by the nozzle. It is clear such additional facilities are not limited to a device according to the invention with a fluidic oscillator nozzle are.

The innovation is described in more detail using an exemplary embodiment. In the associated schematic Drawings shows:

Pig. 2 is an end view of the device according to FIGS. 1 and

Figure 3 is a cross-section along the lines

III - ITT in FIG. 2 with variants shown in dashed lines.

In Fig. 1, a nozzle holder body made of plastic [

denoted by 1. At the front face 2 of the A bristle ring 3 consisting of a single-row arrangement of individual tufts of bristles 4 is attached to the nozzle neck body 1, which frame a centrally arranged in the end face 2 nozzle 5 at a distance. The nozzle 5 acts see e.g. a fluidic oscillator nozzle like her through the DT-OS 25 ^ 3 378 has become known.

The individual tufts of bristles are inserted into holes 6 in the end face 2 of the nozzle holder body glued in.

The nozzle 5 is in a recess 7 in the nozzle holder body 1 used, which is attached to a nozzle holder body axially penetrating channel 8 connects to which a water hose 9 is connected, which with its free end attacks on an adapter, not shown.

The outlet opening of the nozzle 5 can essentially terminate with the end face 2 of the nozzle holder body I. However, it can be of particular advantage if the outlet opening of the nozzle 5 projects over the end face 2 of the nozzle holder body preferably at least 2 mm, as indicated by dashed lines in FIG. 3. This will be discussed in more detail below. A switching device 10 is described in more detail with reference to FIG. 3.

As shown in FIG. 2, the nozzle holder body has a substantially rectangular cross-section with rounded

-8th-

7703420 09/29/77

Edges approximately corresponding to the cross-section of the nozzle 5. Instead of a rectangular cross-section, an oval cross-section can also be selected, as shown, for example, in DT-OS 25 kj> 378. A rectangular or oval cross-section is particularly suitable for fluidic oscillator nozzles, since these have a fan-shaped, outward-widening spray jet with an approximately corresponding spray jet cross-section as the nozzle holder body 1.

It is clear> 4ä &nozzles><äie emit an axially symmetrical spray jet, can also be arranged in holding bodies with a round or square cross-section. Each bristle bundle k has a diameter at its base

a free length of bristles "b" and one

clearance between adjacent bristles "c". The diameter “a” of the bristle bundles 4 at their lower end is in each case between 4 mm and 8 mm, preferably about 5. The free bristle length "b" above the end face 2 is 10 mm to 15 mm, preferably about 12.5 mm. The clearance "c", respectively between two adjacent BorstenbündeInj is 0.6 mm to ₃ O I mm, preferably about 0.8 mm. That is, the axial distance between two adjacent holes for receiving the bristle bundles is 5.6 mm to 6 mm, preferably about 5 ₃ 8 mm.

At the foot of the individual bundles of bristles on the end face 2, the distance "e" is preferably about 0.8 mm at the largest and decreases toward the top to the extent that the bristle bundles v2e apart fan gamsbartartig. In the upper area of the bristle bundles, these are supported among one another to form a tight brush cover.

The switching device 10 (Fig. 3) consists of a cylindrical Slide 11 which is guided axially displaceably in a continuous cylindrical transverse recess 12. The! Transverse recess crosses the channel 8. The slide has

7703420 2S.fl9.77

a through transverse hole 13 · at one end is a leather 14 is provided, which is supported on the outside 15 of the Düsenhalianingskörpers 1 and behind a The projection 16 on the slide 11 engages. There is another protrusion at the other end of the slide 17, the urvter of the force of the spring 14 at the opposite Supports outside 18 of the nozzle holder body and thereby defines one position of the slide, in which the channel 8 is interrupted by the slide, since the transverse bore 13 of the slide is outside the channel 8 comes to rest. The slide 11 has two grooves on the outside with sealing rings 19, 20 on both sides of the channel or the transverse bore 13.

If the slide 11 is moved by hand against the force of the spring to the left in the drawing, the transverse bore is created 13 with the channel 8 to cover and thereby releases the passage for the channel 8. If the pressure on the The slide 11 is released, it automatically moves into its illustrated starting position under the force of the spring back, in which the channel 8 is interrupted by the slide.

It is clear that the transverse bore is also designed in this way. can that by more or less strong pressure on the slide or by a more or less strong aciales Moving the slide 11, the size of the flow area and thus the flow rate of the water to the The nozzle or the water pressure in front of the nozzle can be controlled. Instead of one cross hole, several cross holes can be used be provided in order to achieve such a control.

A variant of the embodiment according to the drawings is that the bristles 3 on a ranmen-shaped Aufsteekteil 19 are arranged, the in Fig. 3

7703420 28.B177

is shown in dashed lines and on a stepped profile 20 on the end face of the nozzle folding body can be plugged, with a projection 21 snapping into a circumferential groove on the nozzle holding body.

This makes it easy to change the bristles.

The new cleaning and massage device works as follows:

If the switching device 10 is pressed by hand, the temperature previously set to its specific flows flows Pressurized water to the nozzle 5, which then emits a pulsating water jet, which can vibrate up to 300 per Second executes. In the case of the nozzle holding body 1 placed with its bristles on the skin to be treated the pulsating beam on the selected skin area, which is bordered by the bristles * i, which in their upper areas form a tight splash protection wall. The one that hits the skin largely unhindered and thereby The jet, which unfolds its full cleaning and massage effect, is encircled by the splash water protection wall Sprayed back space. The water is able to flow away from the gaps between the bristles 4 without hindrance, without that the pressure force of the water jet inhibiting water splash between the nozzle and the to be treated Able to build up skin.

As a result of the brushing movement, the hair tips of the bristle ring also spring into the pore openings and massage them mechanically, gently, creating the cleansing and massage effect of the pulsating water jet is substantially supported.

It is noteworthy that in the main spray zone, where the pulsating The water jet hits the skin, a dense wall of bristles borrows the water outwards in the x-ies

shields, without the n-betwee to splash out of the past, * »gaps flows to the lower ends of the bristle bundles smoothly. A pulsating water jet is only emitted as long as the slide is held in the on position by hand. In the variant according to Fig. 3, the pressure force of the water jet can be sensitively regulated with your slide.

It is clear that the innovation is not limited to an embodiment according to FIGS. 1 to 3 with a switching device IO is.

In order to increase the effect of the water jet emitted by the nozzle 5 still considerably, according to the invention the Nozzle outlet opening the face of the nozzle holder body best protrude at least 2 mm, as indicated by dashed lines in FIG. 3. The operation of the renewal Water rebounding from the skin of the device collects in part on the end face surrounded by the bristle wall of the nozzle holder body 1 and then flows from here through the gaps between the bristle bundles to the outside without the jet from the nozzle being impaired, because this with its outlet opening is the end face of the nozzle holder body protrudes.

Decisive for the renewal effect of the cleaning «7, and massage device is so that the free passage of draining water at a sufficient distance from each other arranged bristle bundles such a diameter and have such a limited length that they spread out in a fan shape upwards and thus in the upper region the bundle of bristles both a dense protective wall against splashing water form, on the other hand have sufficient elasticity for gentle brush massage of the skin, but without to hinder the free access of the water jet emitted by the nozzle to the area of skin to be treated. To the

unhindered outflow of the water jet from the nozzle, it is ₃ as mentioned , particularly advantageous _Λ if the nozzle outlet opening protrudes at least 2 mm beyond the front face of the nozzle holder body ₃ so not flush with the face.

It is clear that the innovation does not apply to the illustrated embodiment and / or to that in FIG. 3 by dashed lines shown variants is limited.
