Connecting device for shower apparatus

A connecting device for a shower apparatus, the connecting device comprising:

• a shower column composed of a bending segment and a straight rod segment, when the shower column is in an installed state, a projection length of the shower column along a vertical projection plane (Y) is (L1), (L1) is between 210 mm and 310 mm, and a projection length of the shower column along a horizontal projection plane (X) is (L2), (L2) is between 290 mm and 350 mm, the bending segment is substantially L-shaped, and a lower part of a free end of the bending segment is provided with a first water outlet, the first water outlet is configured to connect a top spray, and the shower column is provided with a through water outlet channel therein;
• a waterway switching device comprising a valve seat, a water distributing valve core and a knob;
• wherein the valve seat has a hollow inner cavity, a number of partitions are provided in the inner cavity, so that a water inlet chamber and a valve core chamber, which are mutually independent in space but are in fluid communication, are respectively formed at two axial ends, and a first water holding chamber and a second water holding chamber, which are mutually independent in space and have separated waterways, are formed at two radial ends;
• an outer end of the water inlet chamber is provided with a water inlet;
• an outer end of the first water holding chamber is provided with a first connection port, and the first connection port is vertically upward, and is connected to the straight rod segment of the shower column, an outer end of the second water holding chamber is provided with a second water outlet, and the second water outlet is configured to connect an additional water apparatus;
• a vertical partition is formed between the valve core chamber and the first water holding chamber and the second water holding chamber, respectively, the vertical partition is correspondingly provided with at least one first water-passing opening and one second water-passing opening at positions corresponding to the first water holding chamber and the second water holding chamber, so that the valve core chamber is in fluid communication with the first water holding chamber only through the first water-passing opening, and the valve core chamber is in fluid communication with the second water holding chamber only through the second water-passing opening;
• the water distributing valve core is configured to have at least one radial water inlet end and one axial water outlet end, the water distributing valve core is disposed in the valve core chamber, and an outer end of the valve core chamber is arranged with a knob, and the axial water outlet end of the water distributing valve core is driven to be in fluid communication with the first water-passing opening and/or the second water-passing opening by turning the knob.
