Definitions

• the present invention relates to a sanitary shower head.
• Such sanitary showers can be used for shower or bathtubs, which are used in particular for personal hygiene.
• showers or bathtubs regularly have an overhead shower which, when showering, directs a spray jet from above onto a user of the shower, and / or a hand shower which can be guided by the user by hand when showering.
• sanitary showers for showers or bathtubs are known with which a liquid can be delivered with different types of jets, for example in the form of rain jets, full jets, massage jets or pearl jets.
• the changeover between the individual jet types can take place on the sanitary showers, for example, via manually and / or electrically operated changeover elements, for example in the form of valves or solenoid valves.
• the liquid can be directed to the appropriate jet formers for the formation of the desired jet types via the adjusting elements.
• a duck bill valve is a valve that has a valve jacket in the shape of a duck bill. Such valves are also known as "duckbill valves".
• the valve shell is made at least partially of rubber or a synthetic elastomer, such as silicone, and includes a valve base through which the liquid can flow into the duckbill valve.
• the valve shell tapers in a direction of flow of the liquid up to a slot-shaped valve outlet.
• the slot-shaped valve outlet is closed when the sanitary shower is not used. If an inflow of the liquid is activated, for example by opening a corresponding inflow valve in an inflow line of the sanitary shower, the Slit-shaped valve outlet due to elastic deformation of the valve jacket as a result of the P liquid pressure, so that the liquid can pass the duck bill valve. After the inflow valve of the sanitary shower has been closed, the slit-shaped valve outlet closes automatically as a result of the falling liquid pressure, so that dripping of the liquid is prevented.
• the disadvantage of the duck bill valves is that they can calcify after long use of the sanitary shower and then no longer close completely. In addition, particularly thin-walled duckbill valves no longer close completely after just a few uses. This allows dripping of the sanitary shower despite the formation of duck bill valves.
• the object of the invention is therefore to at least partially solve the problems described with reference to the prior art and, in particular, to specify a sanitary shower in which dripping of liquid is reduced or completely prevented.
• a sanitary shower that has at least the following components contributes to this:

• the jet types can be, for example, rain jets, full jets, massage jets and / or pearl jets.
• the liquid can only be dispensed in one or two different jet types at the same time.
• the sanitary shower can have at least one valve in at least one liquid channel, by means of which the liquid can be guided to at least one jet generator for the respective jet type.
• the at least one liquid channel runs in particular through the housing and connects the at least one liquid inlet to the at least one jet generator.
• the liquid channel can also extend, for example, through the jet generator and / or through a nozzle of the jet generator to an outlet opening of the sanitary shower.

• the slit-shaped valve outlet is located at the tip of the duckbill valve and is closed when no liquid is flowing into the sanitary shower head.

• the thickening does not preferably extend over the entire outer surface of the elastic valve jacket. This prevents the at least one liquid valve from not opening or not opening sufficiently at low liquid pressures, or from opening only individual duckbill valves in the case of a plurality of liquid valves at low liquid pressures, so that the sanitary shower dispenses the liquid with an uneven spray pattern.

• the first wall thickness and / or the second wall thickness can in particular be dimensioned orthogonally to an inner surface of the valve shell.
• the first wall thickness can be 0.1 mm to 0.5 mm, preferably (approximately) 0.2 mm.

• the thickening can be at least partially concave.
• the thickening is at least partially concave when viewed against the direction of flow. This can mean that the second wall thickness is smallest in the middle of the slot-shaped valve outlet and increases in size towards the outside parallel to the slot-shaped valve outlet.
• Such a thickening supports the closing of the slit-shaped valve outlet, with the middle area of the slit-shaped valve outlet opening faster when the slit-shaped valve outlet opens because less material has to be displaced or elastically deformed in the middle area of the slotted valve outlet.
