Detailed Description

The invention will be further described in the following with reference to specific embodiments thereof, with reference to the accompanying drawings, in which fig. 1-3:

the utility model provides a can dismantle shower nozzle for washing ground, includes the shower nozzle seat 1 with hollow axis body threaded connection, and communicating through-hole 10 in shaping and the hollow axis body in the shower nozzle seat 1, the lateral wall of shower nozzle seat 1 by supreme first external screw thread 11, outer hexagonal 12 and the second external screw thread 13 with axis body threaded connection of having set gradually down, the upper end of through-hole 10 is provided with the spray core 2 that has orifice 20, and orifice 20 with through-hole 10 is linked together, the shaping has spacing ring platform 21 on the lateral wall of spray core 2, the lower terminal surface of spacing ring platform 21 with the hole at through-hole 10 top is followed and is offseted, and the upper end lid of spray core 2 is equipped with lock nut 3, lock nut 3 the internal thread with 13 looks adaptations of second external screw thread, and when the fit, the top of spray core 2 is run through lock nut 3's middle part.

In the using process, the spray head seat 1, the spray core 2 and the locking nut 3 are installed in advance, and the first external thread 11 and the hollow shaft body provide threads for screw connection to realize installation; during threaded connection, glue is applied to the joint, and stronger sealing performance is achieved.

In the unpicking and washing process, the first external thread 11 is always fixedly connected with the hollow shaft body, the locking nut is screwed out from the second external thread 13, and the spray core is taken out, so that the disassembly, the replacement and the cleaning of the spray head can be realized.

Preferably, a pressing ring 30 is arranged at the upper end of the locking nut 3, and when the locking nut 3 is matched with the second external thread 13, the bottom of the pressing ring 30 abuts against the upper end face of the limit ring table 21. The pressing ring 30 presses down the retainer ring stage 21, so that the spray core 2 is kept in the through hole 10 and prevented from being ejected out of the top of the through hole.

Preferably, the side wall of the spray core 2 is provided with a ring groove 22, the ring groove 22 is located below the limit ring table 21, a sealing ring 23 is arranged in the ring groove 22, and when the spray core 2 is placed in the through hole 10, the outer side of the sealing ring 23 is abutted to the inner wall of the through hole 10. The sealing performance between the side wall of the spray core and the through hole is enhanced.
