The elastic buckle 211 has elasticity, so that the elastic buckle 211 is easily buckled in the first buckling position 131 or the second buckling position 141, and under the pushing of an external force, the elastic buckle 211 deforms and is easily separated from the first buckling position 131 or the second buckling position 141, so that the locking member 200 can be smoothly switched between the first buckling position and the second buckling position, and the moving smoothness of the locking member 200 is further improved.

Referring to fig. 4, 6 and 7, in an embodiment, the locking member 200 includes a locking sleeve 220, the locking sleeve 220 is sleeved on the nozzle body 100, the elastic buckle 211 is disposed at an end of the locking sleeve 220 away from the water pipe connector 400, one of the locking sleeve 220 and the nozzle body 100 is provided with a guide strip 150, the other one is provided with a guide groove 221, the guide strip 150 is slidably disposed in the guide groove 221 along a length direction of the guide groove 221, and the length direction of the guide groove 221 is identical to a direction of the first buckle 131 toward the second buckle 141.

It can be understood that the guide bar 150 and the guide groove 221 are provided to allow the locker 200 to be smoothly moved on the shower body 100, thereby preventing the locker 200 from being moved and deviated. Moreover, the length direction of the guide slot 221 is consistent with the direction of the first buckling position 131 towards the second buckling position 141, so that the locking member 200 can be accurately located at the first buckling position and the second buckling position when moving along the guide strip 150, and the accuracy of the moving position of the locking member 200 is ensured, that is, the stability of the spray assembly 10 is improved. In this embodiment, the length direction of gib block 150 sets up along the axial of lock sleeve 220, the axial setting of lock sleeve 220 is also followed to the direction that first knot position 131 detained position 141 towards the second, lock sleeve 220 has first lock position and second lock position when following its axial displacement promptly, so be favorable to shortening the distance that retaining member 200 removed, and then make retaining member 200 and shower nozzle body 100's structural arrangement compact, be favorable to reducing shower nozzle body 100's volume and reduction in production cost.

Referring to fig. 3, 4 and 6, in an embodiment, the locking member 200 further includes a holding portion 230, the holding portion 230 is disposed on an outer side wall of the locking sleeve 220, and a holding space is formed between the holding portion 230 and the locking sleeve 220. Specifically, in the present embodiment, the holding portion 230 is disposed in a ring shape, and the holding portion 230 is sleeved on the locking sleeve 220. Form through the portion 230 of gripping and grip the space between the lock sleeve 220, be favorable to stretching into the hand and apply external force to retaining member 200 in the space of gripping, and then make things convenient for personnel to assemble and dismantle spray assembly 10, so can improve spray assembly 10's packaging efficiency.

Referring to fig. 6 to 8 and fig. 10 and 12, in an embodiment, the butt joint 111 is disposed in a hollow manner, and a position-limiting portion 112 movable along a radial direction of the butt joint 111 is disposed on the butt joint 111; in the first fastening position, the locking member 200 locks the position-limiting part 112, and the position-limiting part 112 is fixed on the water pipe connector 400 in a limited manner; in the second engaging position, the locking member 200 releases the locking of the position-limiting portion 112, and the position-limiting portion 112 cancels the position-limiting of the water pipe connector 400, so that the water pipe connector 400 can be separated from the head body 100.

It is understood that the specific structure of the stopper 112 is not limited, and it is only necessary that the head body 100 be connected to or separated from the water pipe connector 400. By arranging the limiting part 112 on the butt joint 111, the nozzle body 100 can limit and fix the water pipe connector 400, and a limiting part is not required to be additionally arranged to limit and fix the water pipe connector 400, so that the structure of the spray assembly 10 is simplified.

Further, the locking member 200 is sleeved on the nozzle body 100, the locking member 200 is movably disposed on the nozzle body 100 along the axis thereof, and the limiting portion 112 is movably disposed on the docking head 111 along the radial direction of the docking head 111. When the locking member 200 moves to the first fastening position, the locking member 200 locks the limiting portion 112, and the limiting portion 112 moves along the radial direction of the docking head 111 to limit the water pipe connector 400, so that the docking head 111 is fixedly arranged on the water pipe connector 400; when the locker 200 is moved to the second coupling position, the locker 200 releases the locking of the stopper 112, the stopper 112 is moved in the radial direction of the coupling 111 to be separated from the water pipe connector 400, the stopper 112 cancels the stopper of the water pipe connector 400, and the water pipe connector 400 can be separated from the coupling 111, so that the shower head body 100 can be separated from the water pipe connector 400. By the arrangement, the limiting part 112 on the butt joint 111 limits the water pipe connector 400, and the mode of eliminating the limitation of the position of the water pipe connector 400 is simple, so that the structure of the spray assembly 10 is simplified.

Referring to fig. 7, 10 and 12, in an embodiment, the position-limiting portion 112 includes a position-limiting elastic buckle 113, and the water pipe connector 400 is provided with a position-limiting groove 421; in the first fastening position, the limiting elastic fastener 113 is fastened in the limiting groove 421 to limit the position of the limiting groove 421; in the second fastening position, the limiting elastic fastener 113 is moved out of the limiting groove 421 to cancel the limiting of the position of the limiting groove 421.

It is understood that the shape of the limit groove 421 is not limited, and only needs to be adapted to the structure of the limit snap 113. When the locking member 200 moves to the first locking position, the limiting elastic buckle 113 is locked in the limiting groove 421, so that the nozzle body 100 and the water pipe connector 400 are connected and fixed; when retaining member 200 removed to the second lock position, spacing clip 113 no longer received retaining member 200's locking, and outside spacing clip 113 rebounded out and shifted out to spacing groove 421, spacing clip 113 cancelled the spacing to water pipe head 400 to make water pipe head 400 separate with butt joint 111. Therefore, by arranging the limiting elastic buckle 113 and the limiting groove 421, the mode that the spray head body 100 limits and fixes the water pipe connector 400 is simple, the structure of the spray assembly 10 is simplified, and meanwhile, the spray assembly 10 is convenient to assemble and disassemble.

Referring to fig. 10 to 13, in an embodiment, the locking member 200 is sleeved on the docking head 111 and can move back and forth along the axial direction of the docking head 111, and the locking member 200 is provided with a locking portion 222; in the first engaging position, the locking portion 222 presses and holds the position-limiting elastic buckle 113, so as to press and limit the position-limiting elastic buckle 113 in the position-limiting groove 421; in the second engaging position, the locking portion 222 is retracted from the position-limiting elastic buckle 113, and the position-limiting elastic buckle 113 rebounds out of the position-limiting groove 421.

It can be understood that, the position-limiting elastic buckle 113 has elasticity, and when the locking member 200 is at the first buckling position, the locking portion 222 is pressed on the position-limiting elastic buckle 113, so that the position-limiting elastic buckle 113 can be buckled in the position-limiting groove 421 in a limited manner, thereby ensuring the stability of connection and fixation of the nozzle body 100 and the water pipe structure. Retaining member 200 is when second lock position, and retaining member 200 dodges spacing bullet knot 113, and spacing bullet knot 113 no longer receives the pressure of locking part 222 and holds power to can kick-back and shift out spacing inslot 421, shower nozzle body 100 can separate with water pipe head 400 this moment.
