Further, the outer diameter of the first end 51 of the elastic sleeve 54 is the same as the inner diameter of the first end 51 of the spring 55, so that the elastic sleeve 54 and the spring 55 can tightly hold the water outlet 62 of the flushing valve body 6, the expansion of the water flow impacting the first end 51 of the elastic sleeve 54 can be prevented, and the sealing function is also realized while falling off is prevented. The first end 51 of the elastic sleeve 54 is provided with a second limiting member 542 for preventing the elastic sleeve 54 from sliding along the water flow direction, the water outlet 62 of the flushing valve body 6 is provided with a third limiting member 64 for preventing the elastic sleeve 54 from sliding along the water flow direction, and the second limiting member 542 and the third limiting member 64 are propped against each other. Specifically, the second limiting member 542 is an annular protrusion disposed at an end of the elastic sleeve 54, the third limiting member 64 is an annular groove disposed at the water outlet 62 of the flush valve body 6, and the annular protrusion is disposed in the annular groove.
When the flushing valve body 6 needs to be disassembled, the pin 7 is taken out firstly, so that the connection between the through hole 63 of the flushing valve body 6 and the groove 21 of the water inlet joint 2 (namely the connection between the flushing valve body 6 and the water inlet joint 2) is unlocked; then the flushing valve body 6 moves towards the water outlet joint 3, so that the elastic connecting section 53 of the elastic sleeve 54 and the elastic connecting section 53 of the spring 55 deform, namely, a yielding space is generated in the embedded box 1, so that the flushing valve body 6 (or together with the connecting piece 5) is conveniently taken down from the embedded box 1; the mounting of the flushing valve body 6 and the dismounting of the flushing valve body 6 are operated in opposite directions, which will not be described in detail here. The arrangement of the connecting piece 5 with the elastic connecting section 53 enables the flushing valve body 6 to slide relative to the embedded box 1, so that the disassembling and assembling space of the flushing valve body 6 is reserved in the embedded box 1, and the flushing valve has the advantages of being convenient to disassemble and assemble and easy to maintain.
By adopting the design scheme, the utility model has the beneficial effects that:
1. The embedded box 1 compresses the elastic connecting section 53 by sliding the flushing valve body 6 to connect or separate the flushing valve body 6 and the water inlet joint 2 to the embedded box 1 so as to yield a yielding space in the embedded box 1, which is convenient for taking out the flushing valve body 6, thus the utility model still has the advantages of convenient disassembly and easy maintenance under the condition of ensuring the tight fit of the flushing valve body 6, the water inlet joint 2, the water outlet joint 3 and the connecting piece 5, and is not limited by the narrow space required by the tight fit of the embedded box 1;
2. The flushing valve body 6 achieves the effect of clamping or separating through the simple connecting piece 5 with the elastic connecting section 53, so the manufacturing cost of the integral embedded box 1 is lower, and the cost can be saved by adopting the embedded box 1 of the utility model;
