Shower spray with admixture of ingredients and air

A shower spray device, comprising:

• a body including a handle piece, a central part, and a head part;
• a reservoir provided in said central part, said reservoir having a first storage and supply chamber connected thereto by a first supply bore, for supplying said reservoir with an ingredient, and a second storage and supply chamber connected thereto by a second supply bore, for supplying said reservoir with an ingredient;
• a venturi nozzle;
• a series of ducts connecting said venturi nozzle to said reservoir, said series of ducts being configured such that air is taken through the ingredient and is mixed with particles of the ingredient;
• and
• controlling means for controlling the amount of ingredient supplied from said first and second storage and supply chambers to said reservoir, said controlling means including a first metering screw located in said first supply bore and a second metering screw located in said second supply bore, whereby the air and ingredient mixture from said first and said second storage and supply chambers can be selectively added to a water stream flowing through said shower spray device.

A shower spray device, comprising:

• a body including a central part;
• a reservoir provided in said central part, said reservoir having a storage and supply chamber connected thereto for supplying said reservoir with an ingredient, and said reservoir including a blind bore in said central part, a reservoir base, a step-like offset section adjacent to said reservoir base and extending around an inner circumference of said reservoir, and radial centering webs arranged perpendicularly to said offset section and adjacent to said reservoir base;
• a venturi nozzle;
• a series of ducts connecting said venturi nozzle to said reservoir and being configured such that air is taken through the ingredient and is mixed with particles of the ingredient;
• a reservoir insert mounted on said central part;
• and
• a directing tube extending from said reservoir insert into said reservoir and toward said reservoir base, an end of said directing tube being fixed in said reservoir by said centering webs, said centering webs cooperating with said directing tube to create a flow gap between said reservoir base and said directing tube and to create an annular gap between said directing tube and a reservoir wall, said reservoir being connected to the atmosphere solely by way of said directing tube, whereby the air and ingredient mixture from said reservoir can be admixed to a water stream flowing through said shower spray device.

A shower spray device, comprising:

• a handle piece including an axial through-passage bore extending therethrough, said through-passage bore including a narrowed section;
• a reservoir having a storage and supply chamber connected thereto for supplying said reservoir with ingredient;
• a venturi nozzle;
• a series of ducts connecting said venturi nozzle to said reservoir, said series of ducts including a first duct and a second duct and being configured such that air is taken through the ingredient and is mixed with particles of the ingredient;
• and
• a nozzle element positioned downstream of said narrowed section and upstream of an opening of said first duct, said nozzle element and said opening of said first duct forming said venturi nozzle, said nozzle element including a semicircular flow directing element and said second duct, said flow directing element including a channel-like opening oriented in a downstream direction, said second duct merging into said first duct at one end thereof and opening axially into said channel-like opening at another end thereof, whereby the air and ingredient mixture from said reservoir can be admixed to a water stream flowing through said shower spray device.

A shower spray device, comprising:

• a body, including a head part;
• a reservoir having a storage and supply chamber connected thereto for supplying said reservoir with ingredient, said storage and supply chamber including a base, a discharge bore extending from said base and merging into a supply bore opening into said reservoir, and a threaded bore extending from said supply bore towards an end side of said head part, said supply bore including an inlet having a cone seat sized and shaped to receive a cone point of a metering screw;
• a venturi nozzle;
• and
• a series of ducts connecting said venturi nozzle to said reservoir and being configured such that air is taken through the ingredient and is mixed with particles of the ingredient, whereby the air and ingredient mixture from said reservoir can be admixed to a water stream flowing through said shower spray device.

A shower spray device, comprising:

• a body including a handle piece, a central part, and a head part, said central part located adjacent to said head part;
• first storage means and second storage means located internally of said central part, for storing an ingredient;
• a venturi nozzle;
• a series of ducts connecting said venturi nozzle to said first and said second storage means, said series of ducts including a connecting duct and being configured such that air is taken through the ingredient and is mixed with particles of the ingredient;
• and
• switching means for switching said connecting duct between a first position, in which said connecting duct connects said venturi nozzle to said first storage means, a second position, in which said connecting duct does not connect to either of said storage means, and a third position, in which said connecting duct connects said venturi nozzle to said second storage means, whereby the air and ingredient mixture from said first and said second storage means can be selectively added to a water stream flowing through said shower spray device.
