Soap dosing system for shower and shower with soap dosing system

A shower soap dosing system, comprising:

• at least one soap injection circuit (10), where each soap injection circuit (10) comprises:
• a soap reservoir (11,15),
• a peristaltic pump (12,16) configured to inject soap (19) from the soap reservoir (11,15) into a soap suction and mixing block (20), and
• a non-return valve (14,18) configured to prevent fluid from returning to the soap reservoir (11,15).
• the soap suction and mixing block (20), comprising at least one soap pathway (30), where each soap pathway (30) includes:
• a water inlet (31), configured to receive water (21) from a shower (50) at a regulated temperature,
• a soap inlet (32), configured to receive soap (19) from a soap injection circuit (10).
• a water inlet conduit (37), with at least one section of decreasing section connecting the water inlet (31) with a mixing conduit (39);
• a soap inlet conduit (38) with at least one tapered section (42) of decreasing section connecting the soap inlet (32) with the mixing conduit (39);
• the mixing conduit (39), in which the mixing of water (21) and soap (19) is carried out;
• an outlet conduit (40), with at least one growing section, connecting the mixing conduit (39) with a water and soap mixing outlet (33);
• and
• the water and soap mixing outlet (33), configured for connection with an outlet diffuser (24,25) of the shower (50).
