Description

Shower head with separable nozzles, shower head kit, and maintenance method for shower head

The present invention relates to a shower head, and specifically to a shower head with separable nozzles, as well as a relative shower kit and a relative maintenance method.

It is known, in the sector of faucets and stopcocks, the production of shower heads that comprise

10 a closure plate connected in fluid communication with a water supply, and a supply plate provided with holes for water supply. The two plates can be unity with each other in various ways, often with the interposition of sealing washers or gaskets or also by welding, gluing and perimeter sealing screws.

15 With the passage of time, the holes tend to clog due to an accumulation of the lime contained in the water. To overcome this problem, a known method is to insert nozzles, preferably made of rubber, into the supply holes that protrude from the supply plate. Such nozzles are flexible and allow the removal of lime; in fact, by flexing the nozzles flexibly, the lime, which is known to be fragile, tends to fragment and thereby release the clogged holes.

20 Despite all this, however, in places where the water is particularly hard, it has been observed that, frequently, the total occlusion of the nozzles cannot be released using traditional methods.

As a result, it is often necessary to replace the nozzles themselves. The nozzles are in fact

25 are inserted under pressure from inside the supply plate and are typically made in one piece with a membrane that also acts as a sealing gasket between the plates. In other words, the membrane ensures a hydraulic seal of the water collection chamber and makes it possible to couple the nozzles in the holes for the purposes of a single operation.

30 In practice, the shower head is disassembled and the membrane with the nozzles is removed and replaced.

However, the shower heads of the prior art have numerous drawbacks.

In fact, replacing the nozzles necessarily requires total disassembly of the shower head.

35 This operation is decidedly difficult to perform and, in some cases, in which the plates are welded and / or glued together, it is practically impossible. Such a solution is known from US 2002/158154 A1 and US-A-5730363.

40 It is known that, in the case of an occlusion of the nozzles, the user is often forced to replace the shower head in its entirety.

Often, such a substitution is completely unnecessary since it is not uncommon for only some of the nozzles to be irreparably blocked, generating an irregular and 45 times uncomfortable supply of water through the unobstructed nozzles.

The objective pursued by the present invention is to produce a shower head that remedies the aforementioned drawbacks with reference to the known technique.

50 Such inconveniences have been resolved by a shower head according to claim 1.

Other embodiments of the shower head according to the invention have been described in the following claims.

Additional features and advantages of the present invention will be more clearly highlighted from the following description of a preferred and non-limiting embodiment, in which:

Figure 1 shows a partial perspective view of a shower head according to an embodiment of the present invention; 60 Figure 2 shows a partial cross-sectional view of the shower head of Figure 1;

Figure 3 shows a perspective view of a part of the shower head of Figure 1;

65 Figure 4 shows a side view of part of Figure 3; Figure 5 shows a cross-sectional view of part of Figure 3, along the cross-section line V-V of Figure 4.

With reference to the figures mentioned above, the number 4 globally indicates a shower head.

5 The shower head 4 comprises a closing element 8, capable of being connected in fluid communication with a water supply and a supply plate 12 provided with at least one supply hole 16.

The closing element 8 can be of any shape or have any configuration; preferably, it comprises a hole, for example central, for connection to a water supply.

The supply plate 12 is preferably a flat, thin plate, provided with supply holes 16 and air tightly connected to the closure element 8.

In accordance with one embodiment, the closure element 8 and the supply plate 12 define a water collection chamber 20.

The collection chamber 20 receives the water from the closure element and channels it through the supply holes 16 of the supply plate 12.

According to one embodiment, the shower head comprises a gasket positioned between the closure element 8 and the supply plate 12 so as to define an air-tight collection chamber 20. Said packing is mechanically separated from the supply nozzle 24 associated with the supply holes 16, as best described in the following.

In accordance with a further embodiment, the supply plate 12 and the closure element are connected to each other in a separable manner, by gluing and / or welding. Bonding and / or welding constitute both the mechanical connection and the air tight seal, thereby facilitating the removal of the sealing gasket.

The shower head 4 comprises at least one supply nozzle 24, attached to at least one supply hole 16. The supply nozzle has, for example, the mission of facilitating the cleaning of the supply holes in terms of lime blockages.

Advantageously, the supply nozzle 24 comprises a supply portion 28 having a cylindrical body 32 of a diameter not smaller than the diameter of the respective supply hole 16 in which it is housed.

In this way, the cylindrical body 32 is inserted into the supply hole 16 by a forced coupling, without gaps, which ensures the water tightness of the inner side wall 36 of the supply hole 16. Thanks to such water tightness, water can flow out of the collection chamber 20, only through the nozzle 24 and cannot ooze through the contact portion between the nozzle and the inner side wall 36 of the holes 16.

The supply portion 28 encloses a supply channel 40 that extends from an inlet 44, connected in fluid communication with the collection chamber 20, and which leads to a supply opening 48.

In a mounting configuration of the supply nozzle 24, the supply portion 28 essentially protrudes in a perpendicular direction and away from the supply plate 12, from the side opposite to the collection chamber 20.

Advantageously, the nozzle 24 comprises a coupling portion 52, positioned opposite the supply opening 48, preferably the inlet 44, which has a diameter larger than the diameter of the cylindrical body 32 and which has a toroidal conformation.

Specifically, the coupling portion 52 has a toroidal conformation relative to an axis of revolution parallel to the X-X direction of the feedwater flow.

The toroidal conformation facilitates the insertion and extraction operations of the nozzle 24 in relation to the relative supply holes 17, since the circular geometry prevents the nozzle from sticking in the hole and facilitates the passage of the coupling portion into the hole 16 supply.

The coupling portion 52 is also capable of being flexibly deformed and inserted into the hole 16 of the supply plate 12 from the side of the outer wall 56 of the supply plate 12.

65 The coupling portion 52 terminates against an internal wall 60 of the supply plate 12, opposite the external wall 56.

Preferably, the coupling portion 52 is an O-ring, coaxially positioned relative to the supply portion 28.

5 Preferably, said O-ring is made in one piece with the supply portion 28.

The diameter of the toroidal cross-section of the coupling portion 52 according to a cross-sectional plane in the axial direction X-X is approximately 30-35% of the diameter of the supply hole 16.

Preferably, the outer diameter of the coupling portion is about 1.5-1.6 times the diameter of the supply hole 16.

The collection chamber 20 has an axial thickness greater than the axial thickness of the coupling portion of the nozzles 24, following its insertion into the respective supply holes 16, in order to allow the

Water itself is channeled through the supply channel 40.

According to one embodiment, the nozzle is made of a single piece with polymer material, preferably silicone.

For example, the supply portion 28 is provided with a stop collar 64 having a diameter greater than the diameter of the cylindrical body 32 capable of terminating against the outer wall 56 of the supply plate 12.

Preferably, the diameter of the stop collar 64 is smaller than the diameter of the coupling portion 52.

25 The stop collar 64 and the coupling portion 52, which in both cases have diameters larger than the diameter of the cylindrical body 32, form a pair of notches with the cylindrical body that constitute bilateral limitations with respect to the extraction or insertion of the nozzle 24 in the relative supply hole 16.

Preferably, the axial height of the cylindrical body 32 is essentially equal to the axial thickness of the supply hole 16. Axial thickness refers to the thickness measured along a direction parallel to the axial direction X-X.

According to one embodiment, the stop collar 64 is connected to the supply portion 28, on the side of the supply opening 48, by a connection portion 68, capable of allowing the grip and flexible tightening of the nozzle 24 during assembly and disassembly of the nozzle with respect to the shower head 4.

35 The connecting portion 68 may, for example, have a truncated cone shape or it may have a parabolic cross-section with concavity facing the supply opening 48, in order to facilitate finger grip for mounting / dismounting of the nozzle 24.

The present invention also relates to a shower head kit, comprising at least one replacement nozzle 24, capable of being coupled as a replacement for one of the shower head supply nozzles 24.

Potentially, the kit can comprise the shower head 4 and a plurality of replacement nozzles to replace those that are already coupled to the shower head in case they become clogged by the lime.

The maintenance method for a shower head according to the present invention will now be described.

Specifically, when one or more nozzles clogged with lime need to be cleaned and / or replaced, the first thing is to remove the nozzles from the supply plate 12.

The nozzle 24 is removed by grasping the supply portion 28 of the nozzle with the fingers and squeezing it flexibly in order to provide the nozzle, and especially the coupling portion 52, with a flattened, essentially elliptical cross-section.

55 The nozzle is then removed, taking care to insert the coupling portion into the supply hole at its smallest, flattened end, corresponding to the smallest axis of the ellipse.

The nozzle can then be cleaned with respect to the lime that has accumulated in the supply channel or it can be directly replaced by a new nozzle.

The new nozzle is then inserted into the supply hole directly from the outside of the shower head, that is from the side of the outer wall 56 of the supply plate 12.

65 As with disassembly, the nozzle supply portion 28 is grasped with the fingers and flexibly squeezed in order to give the nozzle, and especially the coupling portion 52, a flattened, essentially elliptical cross section .

The nozzle is then inserted, taking care to insert the coupling portion into the supply hole through its smaller, flattened end, corresponding to the minor axis of the ellipse.

As can be seen from the description, the shower head according to the present invention makes it possible to overcome the drawbacks existing in the shower heads of the known technique.

Specifically, the shower head allows the separation of a single nozzle without having to disassemble or open the shower head itself.

Following the removal of the nozzle, the latter can be cleaned of lime or simply replaced by the user in an extremely simple and quick way.

15 This solution also makes it possible to service shower heads with sealing and supply plates welded or glued together without having to replace them completely.

The production of a shower head kit allows the user to have spare nozzles and quickly make the necessary replacement.

A person skilled in the art can make numerous modifications and variations in the shower head described above, in order to satisfy specific and circumstantial requirements while remaining within the scope of protection of the appended claims.
