Description

Technical Field

[0001] The utility model relates to the technical field of bathtub nozzles, in particular to an ultra-thin bathtub nozzle. Background Art

[0002] During bathtub installation, securing the nozzle holder and sealing it against the tub wall has always been a technical challenge. Traditionally, the nozzle holder is directly fixed to the tub wall, ensuring a tight seal using sealing materials such as O-rings, O-gaskets, or glue. The nozzle holder is then further secured with a nozzle lock nut to ensure stability. However, this installation method presents a significant problem: the nozzle holder protrudes significantly from the tub wall after installation, which not only affects the overall aesthetics of the tub but can also cause inconvenience to consumers during use. To address this issue, some bathtub manufacturers have implemented recessed grooves in the tub wall. By installing the nozzle holder within the recess, the nozzle remains flush with or slightly above the tub wall, thus avoiding the problem of excessive protrusion. However, while this solution solves the protrusion issue, it also presents other drawbacks.

[0003] Specifically, because the nozzle core needs to be installed within the nozzle holder, and the outlet end of the nozzle core is usually completely covered by a nozzle cover, the user needs to grasp the nozzle cover and rotate it during installation or use. This not only makes the installation process cumbersome, reducing the overall aesthetics and ease of use, but also increases the difficulty and cost of manufacturing and adapting it to the bathtub wall. Furthermore, for modern bathtubs pursuing ultra-thin designs, traditional installation methods are even more difficult to meet these requirements. This is because both the protrusion and the recess in the nozzle holder will increase the thickness of the bathtub to a certain extent, thus defeating the original purpose of the ultra-thin design.

[0004] Therefore, it is necessary to develop an ultra-thin bathtub nozzle that can meet the ultra-thin design requirements and ensure that the nozzle is firmly installed and has good sealing performance. Utility Model Content

DETAILED DESCRIPTION

[0028] The embodiments described below are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] See Figures 1-6, this embodiment provides an ultra-thin bathtub nozzle, comprising a nozzle assembly 10, the nozzle assembly 10 including a water inlet end 11 and an opposite water spray end 12, the ultra-thin bathtub nozzle further comprising a face ring 20, a nozzle fixing cover 30 and a plurality of threaded connectors 40, the face ring 20 comprising an outer ring 21 with a through hole in the middle, a connecting ring 22 extending vertically from the through hole of the outer ring 21 and an abutting portion 23 extending from the bottom of the connecting ring 22 to a side away from the outer ring 21, the nozzle assembly 10 passes through the abutting portion 23 and abuts against the abutting portion 23, and the top surface of the nozzle assembly 10 is flush with the outer ring 21, so A circle of side sealing gasket 50 is provided between the abutting portion 23 and the nozzle assembly 10, and a circle of sealing gasket 60 is sleeved on the outside of the connecting ring 22. The threaded connector 40 includes a bolt 41, a first nut 42 and a second nut 43. The bolt 41 passes through the nozzle assembly 10, the side sealing gasket 50 and the abutting portion 23 and fixes the nozzle assembly 10 to the face ring 20 through the first nut 42; the nozzle fixing cover 30 is sleeved on the outside of the nozzle assembly 10, and the bolt 41 passes through the opening opened on the nozzle fixing cover 30 and is fixed by the second nut 43 to install the bathtub ultra-thin nozzle to the mounting hole opened on the tub wall.

[0030] See Figure 3 Preferably, the side sealing rubber pad 50 includes a horizontal rubber pad 51 with a through hole in the middle, and a ring-shaped rubber pad 52 extending vertically from the through hole of the side sealing rubber pad 50. The horizontal rubber pad 51 is arranged between the horizontal surface of the abutting portion 23 and the nozzle assembly 10, and the ring-shaped rubber pad 52 is arranged between the side surface of the abutting portion 23 and the nozzle assembly 10. The side sealing rubber pad 50 of the present application ensures a tight fit between the nozzle assembly 10 and the abutting portion 23 included in the face ring 20 in the horizontal and vertical directions, effectively preventing water leakage and improving installation accuracy.

[0031] See Figure 4 、 Figure 5 Furthermore, a first bend 24 is provided at the end of the abutting portion 23, and the first bend 24 is embedded in the side sealing rubber gasket 50. The provision of the first bend 24 greatly enhances the tight bonding between the face ring 20 and the side sealing rubber gasket 50, forming a more solid waterproof barrier, effectively preventing moisture from penetrating through the tiny gap between the nozzle assembly 10 and the face ring 20. Furthermore, a second bend 25 is provided at the end of the outer ring 21. This covers the side of the sealing gasket 60. At the same time, the design of the second bend 25 also makes the transition between the face ring 20 and the cylinder wall smoother, improving the overall aesthetics.

[0032] See Figure 4 ,Figure 5 Preferably, the sealing gasket 60 is a sealing gasket 60 with an "L"-shaped cross-section. The horizontal end of the sealing gasket 60 is arranged between the outer ring 21 and the cylinder wall, and the vertical end of the sealing gasket 60 is arranged between the connecting ring 22 and the side of the cylinder wall. The sealing gasket 60 of the present application provides a double sealing effect. The horizontal end ensures the sealing between the nozzle assembly 10 and the cylinder wall, and the vertical end further prevents water from leaking from the side, significantly improving the sealing effect. At the same time, the design of the sealing gasket 60 with an L-shaped cross-section enables the sealing gasket 60 to better adapt to the space between the outer ring 21 and the cylinder wall, making the structure more compact, saving space and improving overall stability.

[0033] Furthermore, the horizontal end of the gasket 60 is provided with two rings of protrusions 61 on both its upper and lower surfaces. These protrusions 61 further enhance the sealing effect of the gasket 60. These two rings of protrusions 61 better conform to the surfaces of the outer ring 21 and the cylinder wall, forming a multi-layer seal that effectively prevents water from leaking through the gaps between the gasket 60, the outer ring 21, or the cylinder wall. Furthermore, the center of both the upper and lower surfaces of the horizontal end of the gasket 60 is provided with grooves 62. During installation, the outer ring 21 compresses the gasket 60, causing it to deform slightly, further tightening the connection between the gasket 60, the face ring 20, and the cylinder wall. Consequently, the provision of the gasket 60 fills the gap between the face ring 20 and the cylinder wall, improving the sealing effect.

[0034] Preferably, a bolt seal 70 is disposed between the first nut 42 and the face ring 20. The bolt seal 70 fills the gap between the bolt 41 and the face ring 20 when the first nut 42 is tightened, preventing water from leaking through this gap. Furthermore, the bolt seal 70 provides additional cushioning, reducing direct pressure from the first nut 42 on the face ring 20 during tightening, preventing deformation or damage to the face ring 20 and improving the stability and durability of the overall structure.

[0035] Preferably, the side sealing rubber pad 50 is provided with a plurality of circular holes for the bolts 41 to pass through and which are interference fit with the bolts 41, and a circle of O-shaped ribs are provided on the periphery of the circular holes. This further enhances the sealing and fixing effect of the side sealing rubber pad 50. The interference fit circular holes allow the bolts 41 to fit tightly when passing through, preventing water from leaking from the gap between the bolts 41 and the circular holes. The design of the O-shaped ribs can further compress the side sealing rubber pad 50 when the bolts 41 are tightened, thereby increasing the contact pressure between the side sealing rubber pad 50 and the nozzle assembly 10 and the abutment portion 23, thereby improving the sealing effect. It should be noted that the periphery of the horizontal rubber pad 51 included in the side sealing rubber pad 50 is also provided with a circle of O-shaped ribs, which further enhances the sealing effect of the connection.

[0036] See Figure 4 ,Figure 5 Preferably, the nozzle assembly 10 includes a nozzle seat 13, a nozzle core seat 14 and a nozzle surface cover 15. One end of the nozzle seat 13 is open and extends downward to the accommodating cavity, in which the nozzle core seat 14 is detachably installed. The nozzle surface cover 15 is provided at the opening of the nozzle seat 13, and a water inlet 16 and an air inlet 17 are provided at the end of the nozzle seat 13 away from the opening.

[0037] Furthermore, the nozzle core seat 14 includes a nozzle core 18 and a steel needle rotating shaft 19. The water inlet end 11 of the nozzle core 18 is rotatably connected to the nozzle seat 13. One end of the steel needle rotating shaft 19 is rotatably connected to the nozzle seat 13. The other end of the steel needle rotating shaft 19 is slidably disposed in a chute 110 disposed at the bottom of the nozzle surface cover 15. The steel needle rotating shaft 19 passes through the middle of the nozzle core 18 and is connected to the nozzle core 18. When the steel needle rotating shaft 19 of the present application rotates, it drives the nozzle core 18 to rotate. At the same time, the top of the steel needle rotating shaft 19 swings back and forth in the chute 110, creating an effect in which the massage trajectory is approximately "∞" shaped, thereby providing a richer massage effect and enhancing the user experience.

[0038] Furthermore, a mounting hole is provided on the side of the nozzle assembly 10, within which a light-emitting element 111 is disposed. The provision of light-emitting element 111 enables the nozzle assembly 10 to have an illuminated exterior at the spraying position, as well as at various locations on the nozzle cover 15. While the user enjoys a massage, light-emitting element 111 creates an aesthetically pleasing lighting atmosphere, enhancing the aesthetics of the scene and improving the bathing experience for bathtub users equipped with this nozzle.

[0039] The present invention provides an ultra-thin bathtub nozzle, comprising a nozzle assembly 10, a face ring 20, a nozzle fixing cover 30, and a plurality of threaded connectors 40. The nozzle assembly 10 passes through and is embedded within the face ring 20. The top surface of the nozzle assembly 10 can remain flush with the outer ring 21. During installation, the outer ring 21 abuts against the bathtub wall, thereby achieving the effect of an ultra-thin nozzle. This not only makes the overall appearance of the bathtub more streamlined and beautiful, but also greatly reduces the height of the nozzle protrusion 61 on the bathtub wall, thereby improving the user experience. Furthermore, a side sealing gasket 50 is provided between the abutment portion 23 included in the face ring 20 and the nozzle assembly 10, and a sealing gasket 60 is provided between the outer ring 21 and the bathtub wall. These two sealing structures jointly ensure a tight connection between the nozzle and the bathtub wall, effectively preventing water leakage from the connection. This not only improves the durability of the bathtub but also provides a more reliable user environment for the user. Therefore, the nozzle assembly 10 of the ultra-thin nozzle of the bathtub is embedded in the face ring 20, and only the face ring 20 is partially higher than the wall, that is, the protrusion 61 is low, which does not affect the user experience at all, and achieves installation without the protrusion 61. Therefore, there is no need to reserve a pit for installation on the wall of the bathtub. This design has a simple structure, greatly reduces mold investment, reduces production costs, is more convenient to install and use, and there is no pit on the bathtub wall, which is more integrated, simple and beautiful.

[0040] The above disclosures are merely some preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
