[0002] With the continuous advancement of science and technology, people's requirements for quality of life are getting higher and higher, and massage bathtubs are quickly entering people's lives. The end caps of existing nozzles are mostly fixed to the inner core, so that the end caps cannot move freely relative to the inner core, resulting in the stability of the inner core being reduced due to the rotation of the end caps. For this reason, the inventor proposed a close-fitting nozzle. Utility Model Content

[0035] Example 1

[0036] See also Figure 1This embodiment provides a close-fitting nozzle to solve the problem that the stability of the inner core of the existing massage bathtub nozzle is easily affected by the end cover, thereby avoiding unexpected linkage between the inner core and the end cover.

[0037] In this embodiment, the close-fitting nozzle includes an inner core 20 screwed into the base 10, and an end cover 30 opposite to the inner core 20 is rotatably clamped on the top of the base 10. The outer periphery of the end cover 30 has a step 31 abutting against the top surface of the inner core 20. The end surface of the end cover 30 abuts against the top surface of a bead ring 51 arranged inside the inner core 20 and equipped with a spray bead 50. A surface cover 40 is rotatably buckled on the top of the base 10, and the surface cover 40 is sleeved on the outside of the end cover 30. A sealing assembly is sandwiched between the surface cover 40 and a locking nut 60 screwed on the outside of the base 10.

[0038] This embodiment prevents the stability of the inner core 20 from being affected by the end cap 30 and avoids unexpected linkage between the inner core 20 and the end cap 30 by rotatably connecting the end cap 30 to the inner wall of the base 10 and allowing the end cap 30 to simultaneously form abutment restrictions on the inner core 20 and the bead ring 51.

[0039] Specifically, a lock nut 11 is fixedly connected to the inside of the base 10, and the inner core 20 is integrally screwed into the inside of the lock nut 11. By means of the threaded connection between the lock nut 11 and the inner core 20, the inner core 20 can be fixed as a whole inside the base 10; a limiting ring 12 is fixedly connected to the inner wall of the upper end of the base 10, and the limiting ring 12 is constructed into a ring shape coaxially arranged with the base 10. The end cover 30 is integrally rotatably clamped on the limiting ring 12, and by means of the rotatable clamping cooperation between the limiting ring 12 and the end cover 30, the end cover 30 can be integrally rotatably connected to the inside of the base 10; the top end of the base 10 has an outwardly extending annular hanging platform 15, and a mounting groove 13 for clamping the sealing ring 14 is provided on the circumferential surface of the hanging platform 15.

[0040] It should be noted that the step 31 is fixed to the outer wall of the end cover 30, and the step 31 is configured to be annularly arranged coaxially with the end cover 30, and a slot 32 is provided on the circumferential surface of the step 31 to be engaged with the limit ring 12 formed on the inner wall of the base 10, and the slot 32 is configured to be annularly arranged coaxially with the step 31, and the end cover 30 is rotatably arranged inside the base 10 by means of the rotational engagement of the slot 32 and the limit ring 12; the top plate of the end cover 30 is overlapped on the hanging platform 15 of the base 10, and the lower end surface of the step 31 is rotatably fitted and abutted against the top surface of the inner core 20, and the step 31 is used to engage with the inner wall of the base 10. The abutment of the top surface of the inner core 20 can more stably restrict the inner core 20 as a whole inside the base 10 to prevent the inner core 20 from rotating outward; the bead ring 51 is integrally inserted into the interior of the inner core 20, and the spray beads 50 can be rotatably restricted in the bead ring 51. The top surface of the bead ring 51 is lower than the top surface of the inner core 20, and the inner end of the end cover 30 is inserted into the interior of the inner core 20. At the same time, the inner end surface of the end cover 30 and the top surface of the bead ring 51 can be rotatably fitted and abutted. By utilizing the abutment between the inner end surface of the end cover 30 and the top surface of the bead ring 51, the bead ring 51 and the spray beads 50 can be stably restricted inside the inner core 20.

[0041] It should also be noted that the face cover 40 is integrally sleeved on the outside of the hanging platform 15, and the end cover 30 is integrally arranged on the inside of the face cover 40. The face cover 40 is constructed into a Z shape along the cross section. The lower end of the face cover 40 is folded inward and buckled under the hanging platform 15. The upper end of the face cover 40 is folded outward and is parallel to the hanging platform 15 as a whole. The sealing ring 13 is clamped between the hanging platform 15 and the face cover 40 to achieve a sealed connection between the face cover 40 and the base 10. The sealing assembly includes a sealing gasket 41 and a locking ring 42. The locking ring 42 is sleeved on the outside of the base 10. The sealing gasket 41 is clamped between the upper end of the face cover 40 and the locking ring 42, and the locking ring 42 has an inner bottom surface abutting against the lower end surface of the face cover 40. During installation, the locking nut 60 and the locking ring 42 are placed on the inner and outer sides of the bathtub wall. By tightening the locking nut 60, the locking nut 60 and the locking ring 42 can clamp the bathtub wall. At the same time, the locking ring 42 can be used to clamp and fix the sealing gasket 41 and the surface cover 40.

[0042] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
