Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a rotatable toilet nozzle and a toilet.

[0004] This utility model is achieved by the following method: a rotatable toilet nozzle, comprising:

[0006] It also includes a first limiting groove, which is circumferentially arranged around one of the first connecting portion and the second connecting portion, and a first limiting member, which is disposed on the other of the first connecting portion and the second connecting portion and cooperates with the first limiting groove; the first limiting member is disposed in the first limiting groove and is limited by the first limiting groove in the axial direction and rotatably cooperates with the first limiting groove in the circumferential direction, so as to guide the nozzle to rotate around the axis within a preset range, so as to change the water outlet angle of the nozzle.

One of the first locking member and the second locking member is a limiting rubber pad, and the other of the first locking member and the second locking member is a retaining ring. During the rotation of the nozzle, friction is generated between the limiting rubber pad and the outer or inner circumferential surface of the retaining ring. The diameter of the mating surface between the retaining ring and the limiting rubber pad changes with the circumferential direction of the retaining ring, and the limiting rubber pad can contact and squeeze with the retaining ring.

[0014] Preferably, the retaining ring has at least two arc-shaped segments with different diameters.

When the gap is located inside the limiting rubber pad, the outer diameter of the first arc-shaped segment is less than the distance between the inner side of the limiting rubber pad and the axis, and the outer diameter of the second arc-shaped segment is greater than the distance between the inner side of the limiting rubber pad and the axis.

[0015] Preferably, the angle between the two ends of the second arc segment and the axis is greater than the angle that the first limiting member can rotate through in the first limiting groove.

[0016] Preferably, both the first connecting part and the second connecting part are tubular, the first connecting part is sleeved inside the second connecting part or the second connecting part is sleeved inside the first connecting part, and the first connecting part and the second connecting part are connected to each other and connected by the first limiting groove and the first limiting member.

[0017] The first limiting groove is disposed on the outer peripheral surface of the first connecting part, and the first limiting member is disposed on the inner peripheral surface of the second connecting part; or, the first limiting groove is disposed on the outer peripheral surface of the second connecting part, and the first limiting member is disposed on the inner peripheral surface of the first connecting part; at least two sets of first limiting grooves and first limiting members are symmetrically disposed on the first connecting part or the second connecting part.

[0018] Preferably, it also includes an anti-rotation plate, one end of which is connected to the toilet, and the other end is provided with a clearance hole through which the nozzle connector passes.

[0020] The beneficial effects of this utility model are as follows: This utility model provides a rotatable toilet nozzle and toilet. Compared with the prior art, this utility model has at least the following technical effects: 1. Through the circumferential sliding cooperation between the first limiting member and the first limiting groove, the nozzle can rotate continuously around the axis, breaking through the traditional fixed gear limitation and realizing stepless adjustment of the water outlet direction to adapt to the optimal angle requirements under different water pressures; the structure of the first limiting member embedded in the first limiting groove prevents the nozzle from falling off axially, ensuring the structural stability during rotation and avoiding nozzle position deviation due to water pressure fluctuations; when there are large differences in water pressure in different usage environments or differences in ceramic molding between different batches, the nozzle direction can be adjusted by rotation to obtain the optimal water outlet direction, thereby improving the toilet flushing effect. 2. The first stop and the second stop are circumferentially limited to the first limiting member, preventing the first limiting member from falling out of the first limiting groove and limiting the rotation range of the nozzle; the first limiting member and the first stop are elastic or flexible, which facilitates mutual compression and deformation during assembly, allowing the first limiting member to enter the first limiting groove. 3. A first locking component is provided on the nozzle, and a second locking component is provided on the nozzle connector. The two components work together to provide pre-tightening force to the nozzle along the rotation direction, achieving self-locking at any rotation angle. This prevents accidental nozzle angle deviation caused by water flow impact or vibration, ensuring angle stability after adjustment. Users can complete angle adjustment and locking without additional tools, improving the user experience. 4. The changing dimensions of the retaining ring's mating surface alter the pressure on the limiting rubber pad with the rotation angle, facilitating initial assembly of the nozzle and nozzle connector, and subsequent clamping and locking after angle adjustment. 5. The inner diameter of the first arc-shaped segment of the retaining ring is designed to be larger than the distance between the outer side of the limiting rubber pad and the axis. This provides clearance during initial assembly of the nozzle and nozzle connector, allowing the limiting rubber pad to easily fit into the space within the retaining ring. The inner diameter of the second arc-shaped segment is smaller than the distance between the outer side of the limiting rubber pad and the axis, allowing the retaining ring and limiting rubber pad to clamp and lock together after nozzle angle adjustment, thus locking the nozzle's water outlet angle. The limiting rubber pad is located on the outer side of the retaining ring, and so on. 6. The included angle at both ends of the second arc segment is greater than the rotatable angle of the first limiting rib, ensuring that the locking range of the retaining ring covers the maximum rotation range of the nozzle. 7. The anti-rotation plate is fixed to the toilet body, completely eliminating the slight self-rotation of the nozzle caused by water flow impact; the combination of the sealing ring and sealing gasket prevents leakage at the interface, and multiple sealing guarantees adapt to high water pressure conditions.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Please see Figures 1 to 12 A rotatable toilet spray head includes:

[0038] The nozzle 1 has a water outlet and a first connecting part 15; the nozzle connector 2 has a water inlet and a second connecting part 16; the nozzle 1 is connected to the nozzle connector 2 through the connection of the first connecting part 15 and the second connecting part; it also includes a first limiting groove 3, which is circumferentially arranged around one of the first connecting part 15 and the second connecting part 16; it also includes a first limiting member 4, which is disposed on the other of the first connecting part 15 and the second connecting part 16 and cooperates with the first limiting groove 3; the first limiting member 4 is disposed in the first limiting groove 3 and is limited in the axial direction and rotatably cooperates with the first limiting groove 3 in the circumferential direction, so as to guide the nozzle 1 to rotate around the axis within a preset range, thereby changing the water outlet angle of the nozzle 1. Through the circumferential sliding engagement of the first limiting member 4 and the first limiting groove 3, the nozzle 1 can rotate continuously around the axis, breaking through the limitations of traditional fixed positions and realizing stepless adjustment of the water outlet direction to adapt to the optimal angle requirements under different water pressures. In some embodiments, the first limiting member 4 and the first limiting groove can also be interference-fitted to provide a certain circumferential rotational preload. The structure of the first limiting member 4 embedded in the first limiting groove 3 prevents the nozzle 1 from axially falling off, ensuring structural stability during rotation and avoiding displacement of the nozzle 1 due to water pressure fluctuations. When there are significant differences in water pressure in different usage environments or differences in the molding of different batches of ceramics, the direction of the nozzle 1 can be adjusted by rotation to obtain the optimal water outlet direction, thereby improving the flushing effect of the toilet 13.

[0039] Please see Figures 1 to 3 , Figure 6 , Figure 7 , Figure 9 Preferably, at least one end of the first limiting slide groove 3 is provided with a first stop portion 8. When the nozzle rotates to a preset angle, the first limiting member 4 and the first stop portion 8 are mutually limited in the circumferential direction. The first stop portion 8 is used to prevent the first limiting member 4 from coming out of the first limiting slide groove 3 in the circumferential direction and to limit the rotation range of the first limiting member 4 relative to the first limiting slide groove 3.

[0040] The first limiting member 4 or the first stop 8 is an elastic member or a flexible member, so that the first limiting member 4 can pass over the first stop 8 and enter the first limiting groove 3; in this embodiment, the elastic member or the flexible member refers to a material that can undergo a certain deformation, so that the first limiting member 4 can pass over the first stop 8.

[0041] The first limiting groove 3 also includes a second stop 14, the first limiting member 4 and the second stop 14 are mutually limiting and engaged in the axial direction, and the second stop 14 is used to prevent the first limiting member 4 from coming out of the first limiting groove 3 in the axial direction;

[0042] The first limiting groove 3 includes at least two sets of first stop portions 8 and second stop portions 14, the first stop portions 8 and the second stop portions 14 forming the first limiting groove 3 (e.g., Figure 6 (As shown). The first stop 8 and the second stop 14 are provided to circumferentially and axially limit the first limiting member 4 to prevent the first limiting member 4 from falling out of the first limiting groove 3 and to limit the rotation range of the nozzle 1. The first limiting member 4 is the first stop 8, which is an elastic or flexible member, so that the two can be squeezed and deformed during assembly, so that the first limiting member 4 can enter the first limiting groove 3.

[0043] Please see Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8 Preferably, the nozzle 1 is provided with a first locking member, and the nozzle connector 2 is provided with a second locking member that cooperates with the locking member. The first locking member and the second locking member cooperate to provide a pre-tightening force to the nozzle 1 in the rotation direction. The first locking member on the nozzle 1 and the second locking member on the nozzle connector 2, together, provide a pre-tightening force to the nozzle in the rotation direction, achieving self-locking at any rotation angle. This prevents the nozzle 1 angle from accidentally shifting due to water flow impact or vibration, ensuring the angle is stable after adjustment. Users can complete angle adjustment and locking without additional tools, improving the user experience.

[0044] Please see Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8 Please see Figures 1 to 12Preferably, the nozzle 1 further includes a first cover 17, which is disposed at one end of the outlet of the first connecting part 15. The nozzle connector further includes a second cover 18, which is disposed at one end of the second connecting part 16 near the first connecting part 15. The first cover 17 and the second cover 18 cover each other. The first cover 17 is provided with a first locking member on the side facing the second cover 18, and the second cover 18 is provided with a second locking member on the side facing the first cover 17. One of the first locking member and the second locking member is a limiting rubber pad 5, and the other of the first locking member and the second locking member is a retaining ring 6. During the rotation of the nozzle, friction is generated between the limiting rubber pad 5 and the outer or inner circumferential surface of the retaining ring 6. The diameter of the mating surface between the retaining ring 6 and the limiting rubber pad 5 changes with the circumferential direction of the retaining ring 6, and the limiting rubber pad 5 can contact and squeeze with the retaining ring 6. The change in the size of the mating surface between the retaining ring 6 and the limiting rubber pad 5 causes the pressure on the limiting rubber pad 5 to change with the rotation angle, facilitating the initial docking and assembly of the nozzle 1 and the nozzle connector 2, as well as the mutual compression and locking after the angle is adjusted during assembly. Preferably, the end face of the nozzle 1 facing the nozzle connector 2 has a mounting groove 19 surrounding the outside of the first connecting part 15, and the limiting rubber pad 5 is disposed in the mounting groove 19; the side of the limiting rubber pad 5 away from the axis has a gap with the wall of the mounting groove 19 away from the axis, and the retaining ring 6 passes through the gap; or, the side of the limiting rubber pad 5 facing the axis has a gap with the wall of the mounting groove 19 close to the axis, and the retaining ring 6 passes through the gap. The gap can lock the retaining ring 6 after the nozzle 1 rotates, thereby locking the nozzle 1 angle, and the nozzle 1 will not rotate without external force.

[0045] Please see Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8Preferably, the retaining ring 6 has at least two arc-shaped segments with different diameters. When the gap is located outside the limiting rubber pad 5, the inner diameter of the first arc-shaped segment 61 is greater than the distance between the outer side of the limiting rubber pad 5 and the axis, and the inner diameter of the second arc-shaped segment 62 is less than the distance between the outer side of the limiting rubber pad 5 and the axis. When the gap is located inside the limiting rubber pad 5, the outer diameter of the first arc-shaped segment 61 is less than the distance between the inner side of the limiting rubber pad 5 and the axis, and the outer diameter of the second arc-shaped segment 62 is greater than the distance between the inner side of the limiting rubber pad 5 and the axis. The inner diameter of the first arc-shaped segment 61 of the retaining ring 6 is designed to be greater than the distance between the outer side of the limiting rubber pad 5 and the axis. This allows for clearance when the nozzle 1 and nozzle connector 2 are initially connected, making it easy for the limiting rubber pad 5 to be inserted into the space within the retaining ring 6. The inner diameter of the second arc-shaped segment 62 is smaller than the distance between the outer side of the limiting rubber pad 5 and the axis. This allows the retaining ring 6 and the limiting rubber pad 5 to press against each other to achieve a tight fit after the nozzle 1 angle is adjusted, thereby locking the water outlet angle of the nozzle 1. The limiting rubber pad 5 is located on the outer side of the retaining ring 6, and so on.

[0046] Please see Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8 Preferably, the included angles between the two ends of the second arc-shaped segment 62 and the axis are greater than the angle through which the first limiting member 4 can rotate in the first limiting groove 3. The included angles between the two ends of the second arc-shaped segment 62 are greater than the rotatable angle of the first limiting member 4, ensuring that the limiting and locking range of the retaining ring 6 covers the maximum rotation range of the nozzle 1.

[0047] Please see Figures 1 to 3 , Figure 6 , Figure 7 , Figure 9 Preferably, both the first connecting portion 15 and the second connecting portion 16 are tubular. The first connecting portion 15 is sleeved inside the second connecting portion 16, or the second connecting portion 16 is sleeved inside the first connecting portion 15. The first connecting portion 15 and the second connecting portion 16 are connected and linked by the first limiting groove 3 and the first limiting member 4. The first limiting groove 3 is disposed on the outer peripheral surface of the first connecting portion 15, and the first limiting rib 4 is disposed on the inner peripheral surface of the second connecting portion 16. Alternatively, the first limiting groove 3 is disposed on the outer peripheral surface of the second connecting portion 16, and the first limiting member 4 is disposed on the inner peripheral surface of the first connecting portion 15. At least two sets of first limiting grooves 3 and first limiting members 4 are symmetrically disposed on the first connecting portion 15 or the second connecting portion 16.

[0048] Please see Figures 1 to 3 , Figure 6 , Figure 7 , Figure 9 , Figure 12Preferably, the first limiting member 4 is a limiting rib. When the first limiting groove 3 is located on the outer peripheral surface of the nozzle 1, the first limiting rib is located on the inner peripheral surface of the nozzle connector 2. The outer peripheral surface of the nozzle 1 is provided with an axial guide groove 7. The size of the guide groove 7 matches the size of the first limiting rib. The first stop 8 is provided at the connection between the first limiting groove 3 and the guide groove 7. The guide groove 7 guides the first limiting rib to accurately enter the first limiting groove 3, avoiding misalignment during assembly. The first stop 8 is provided at the connection between the guide groove 7 and the first limiting groove 3 to form a mechanical barrier, preventing the first limiting rib from coming out of the first limiting groove 3. This prevents the nozzle 1 and nozzle connector 2 from rotating from the first limiting groove 3 to the guide groove 7 during use after assembly, thus avoiding the nozzle 1 and nozzle connector 2 from being pushed apart by water flow. The size design of the first stop 8 facilitates the first limiting rib to pass over the first stop 8 with slight deformation and be guided into the first limiting groove 3. When the first limiting rib is in the guide groove 7, the limiting rubber pad 5 is exactly in contact with the first arc-shaped segment 61 (the gap is located on the outside of the limiting rubber pad 5), such as Figure 8 As shown in Figure A, when nozzle 1 and nozzle connector 2 are mated, the limiting rubber pad 5 will not be blocked by the retaining ring 6, allowing nozzle 1 and nozzle connector 2 to be smoothly assembled. After the first limiting rib passes the first stop 8, the limiting rubber pad 5 is now opposite the second arc-shaped segment 62, in an interference fit state of mutual compression, thus locking nozzle 1 after rotation. Figure 8 As shown in B. Figure 12 As shown, the water outlet angle of nozzle 1 can be adjusted within a range of 20° upward and 40° downward; of course, it can also be other ranges, such as 30° upward and 50° downward, and is not limited to these. It can be adjusted according to actual production needs.

[0049] Please see Figures 1 to 3 , Figure 6 , Figure 7 , Figure 9 Preferably, one end of the first limiting rib is an arc-shaped surface, and the other end is a flat surface. When the first limiting rib is in the guide groove 7, the end face of the first stop part 8 opposite to the arc-shaped surface of the first limiting rib is also an arc-shaped surface, and the arc-shaped surface of the first stop part 8 forms an obtuse angle with the guide groove 7. The end face of the first stop part 8 away from the arc-shaped surface of the first limiting rib is also a flat surface, and forms an acute angle with the first limiting groove 3. The arc-shaped surface makes it easier for the first limiting rib to pass through the first stop part 8 and enter the first limiting groove 3; after entering, it is blocked by the flat surface forming the acute angle, making it more difficult for the first limiting rib to come out of the first limiting groove 3. Preferably, the second stop part is an axial limiting rib.

[0050] Please see Figure 1 , Figures 10 to 12Preferably, it also includes an anti-rotation plate 9, one end of which is connected to the toilet 13, and the other end has a clearance hole through which the nozzle connector 2 passes. A mounting nut 10 and a sealing gasket 11 are respectively provided on both sides of the clearance hole. A sealing ring 12 is also provided between the circumferential surfaces of the connection between the nozzle 1 and the nozzle connector 2. The anti-rotation plate 9 is fixed to the toilet 13 body, completely eliminating the slight self-rotation of the nozzle 1 caused by water flow impact; the sealing ring 12 and the sealing gasket 11 together prevent leakage at the interface, and multiple sealing guarantees adapt to high water pressure conditions.

[0051] Please see Figures 10 to 12 A toilet 13 includes a toilet bowl, wherein the nozzle is mounted on the upper part of the rear side of the toilet bowl, and the water outlet of the nozzle 1 is perpendicular to the water inlet of the nozzle.

[0052] The working principle of this utility model is as follows:

[0053] First, fix the nozzle connector 2 to the toilet seat 13 using the anti-rotation plate 9, mounting nut 10, and sealing gasket 11. Then, install the nozzle 1. First, align the first limiting member 4 on the nozzle connector 2 with the guide groove 7, and push the nozzle 1 to push the first limiting member 4 into the guide groove 7. Then, rotate the nozzle 1 so that when the nozzle connector 2 and / or the nozzle 1 are slightly deformed, the first limiting member 4 can pass over the first stop 8 and enter the first limiting groove 3. Due to the obstruction of the first stop 8, the first limiting member 4 cannot move out of the first limiting groove 3. Once disengaged from the sliding groove 3, the first limiting member 4 can move along the first limiting groove 3 to adjust the water outlet angle of the nozzle 1. Furthermore, due to the cooperation between the retaining ring 6 and the limiting pad, within the sliding range of the first limiting member 4 in the first limiting groove 3, the limiting pad and the retaining ring 6 are in an interference fit state, which can lock any angle. After adjusting the water outlet angle of the nozzle 1, the retaining ring 6 and the limiting pad 5 are squeezed against each other to achieve a tight fit, thereby locking the water outlet angle of the nozzle 1 and preventing the nozzle 1 from shaking and loosening.
