Accordingly, the water returning channels 222 comprise a first water returning channel 2221 and a second water returning channel 2222, which are independent from each other.
Accordingly, the water returning joints 226 comprise a first water returning joint 2261 and a second water returning joint 2262. The first water returning joint 2261 is in communication with the first water returning channel 2221, and the second water returning joint 2262 is in communication with the second water returning channel 2222.
Accordingly, the water guiding grooves 223 comprise a first diverting groove 2231 and a second diverting groove 2232. The first diverting groove 2231 is in communication with the first water returning channel 2221, and the first flushing joint 2111 is in communication with the first diverting groove 2231. The second diverting groove 2232 is in communication with the second water returning channel 2222, and the second flushing joint 2112 is in communication with the second diverting groove 2232.
The switching valve of the spray pipe switching valve 11 can switch the waterways to control the water to return into the first water returning channel 2221 and/or the second water returning channel 2222, and thereby control the water being sprayed from the corresponding spray pipe. For example, when water returns into the first return runner 221, one spray pipe realizes the forward flushing; when water returns into the second water returning channel 2222, the other spray pipe realizes the backward flushing, so as to satisfy different flushing needs for the users.
In an embodiment, as shown in
In this embodiment, one end of the rotating valve core 22 is configured with the chuck 4, which may be connected with the rotating valve core 22, or may be arranged at an interval from the rotating valve core 22. The chuck 4 is used to be clamped with a connecting sleeve (e.g., a pivot sleeve 63) of a rear end of the seat 6. The center of the pivot sleeves 63 is the pivot shaft or the pivot center of the seat 6. Thus, the chuck 4 can be rotated with the seat 6 as a whole. The chuck 4 is provided with more than two slots 41 along the circumferential direction, and the water supply joints 225 and the water returning joints 226 are clamped in the slots 41, respectively. When rotating, the chuck 4 drives the water supply joints 225 and the water returning joints 226 to rotate with it as whole, which in turn drives the rotating valve core 22 to rotate with them as a whole. The arrangements of the water pipes connected between the spray pipe switching valve 11 and the water supply joints 225 and the water pipes connected between the spray pipe switching valve 11 and the water returning joints 226 will not be affected.
