[0052] When the user uses the bathtub 7 for bathing, when the user needs to rest in a lower lying position, the user holds the headrest 2 and rotates the headrest 2 to the first state, at which time the concave portion 22 of the headrest is located obliquely above the convex portion 21 of the headrest, and the concave portion 22 of the headrest is used to support the back of the user's head, and the convex portion 21 of the headrest is used to support the user's neck, providing a more comfortable lying position. When the user wants to use a higher lying position to operate a mobile phone, tablet, etc. to watch movies or TV series, the user holds the headrest 2 and rotates the headrest 2 to the second state, and the concave portion 22 of the headrest is located obliquely below the convex portion 21 of the headrest, and at this time, the convex portion 21 of the headrest is used to support the back of the user's head, thereby raising the user's head, and then providing a higher lying position, so that the user can watch movies or TV series while bathing.

[0053] In one embodiment, if Figure 1-3 As shown, the headrest concave portion 22 is arranged next to the headrest convex portion 21 .

[0054] In this embodiment, there is no gap between the headrest recess 22 and the headrest protrusion 21, and the convex surface of the headrest protrusion 21 is connected to the concave surface of the headrest recess 22. When the user rotates the headrest 2 to the first state, the bottom side of the headrest recess 22 and the top side of the headrest protrusion 21 support the user's neck, thereby improving the user's experience.

[0055] In one embodiment, if Figure 3-5 As shown, a fixing sleeve 3 is provided on the side of the headrest 2 facing the suction cup 1 , and a rotating sleeve 4 is connected to the assembly sleeve 11 . The rotating sleeve 4 is connected to the fixing sleeve 3 .

A rotating sleeve 4 is sleeved on the assembly sleeve 11, and the rotating sleeve 4 can rotate relative to the assembly sleeve 11. The rotating sleeve 4 is fixedly connected in the fixing sleeve 3. When the user rotates the headrest 2, the fixing sleeve 3 and the rotating sleeve 4 rotate integrally relative to the assembly sleeve 11. Such an arrangement facilitates the pivotable connection between the headrest 2 and the assembly sleeve 11, avoids the assembly sleeve 11 from wearing the headrest 2 when the headrest 2 is rotated, and improves the assembly stability.

[0057] In one embodiment, if Figure 3-5 As shown, a sealing ring 5 is provided between the fixed sleeve 3 and the rotating sleeve 4.

[0058] If water splashes into the fixed sleeve 3, it is easy to mold in a humid environment and produce odor. In this embodiment, a sealing ring 5 is arranged between the fixed sleeve 3 and the rotating shaft sleeve 4 to prevent water from splashing into the fixed sleeve 3, thereby avoiding the above defects.

[0059] As required, a plurality of sealing rings 5 ​​may be arranged between the fixed sleeve 3 and the rotating sleeve 4 to improve the sealing effect.

[0060] In one embodiment, if Figure 4 and Fig. 9 As shown, an annular groove 41 is provided on the rotating sleeve 4, and the sealing ring 5 is installed in the annular groove 41, which improves the installation reliability of the sealing ring 5.

[0061] In one embodiment, if Figure 3-6 and Fig. 9 As shown, the rotating sleeve 4 is sleeved on the assembling sleeve 11, and the rotating sleeve 4 and the assembling sleeve 11 are connected by threads.

[0062] In this embodiment, an external thread is provided on the outer surface of the assembly sleeve 11, and an internal thread is provided on the inner surface of the rotating sleeve 4. During assembly, the rotating sleeve 4 is sleeved on the assembly sleeve 11, and the internal thread is engaged with the external thread. With such a configuration, the rotating sleeve 4 can rotate relative to the assembly sleeve 11, and the rotating sleeve 4 can be prevented from being separated from the assembly sleeve 11, further improving the assembly stability of the rotating sleeve 4 and the assembly sleeve 11. Generally, when the user operates the headrest 2 to switch between the first state and the second state, the headrest 2 is rotated half a circle in the forward direction, and then the headrest 2 is rotated half a circle in the reverse direction, so that the rotating sleeve 4 will not be separated from the assembly sleeve 11.

The inner sleeve 31 is integrally connected to the top plate of the fixed sleeve 3. During assembly, one end of the rotating sleeve 4 is connected between the inner sleeve 31 and the fixed sleeve 3, and the cylinder wall of the inner sleeve 31 and the cylinder wall of the fixed sleeve 3 play a limiting role on the rotating sleeve 4, reducing the radial shaking of the rotating sleeve 4. The connecting shaft 6 passes through the assembly sleeve 11 and the rotating sleeve 4, and one end of the connecting shaft 6 can be pivotally connected to the inner sleeve 31, and the connection of the connecting shaft 6 will not affect the assembly of the rotating sleeve 4.

[0071] One end of the connecting shaft 6 can simply be inserted into the inner sleeve 31, or a convex ring is provided at one end of the connecting shaft 6, and an annular groove is provided on the inner surface of the inner sleeve 31. The convex ring is loosely fitted in the annular groove, thereby improving the connection stability between the inner sleeve 31 and the assembly sleeve 11 and preventing the fixed sleeve 3 from detaching along the axial direction.

[0072] In one embodiment, if Figure 4 As shown, one end of the connecting shaft 6 is connected to the inner sleeve 31 through a thread.

[0073] In this embodiment, an external thread is provided at one end of the connecting shaft 6, and an internal thread is provided on the inner surface of the inner sleeve 31. During assembly, the end of the connecting shaft 6 with the external thread is connected to the inner sleeve 31, and the external thread is meshed with the internal thread. Generally, when the user operates the headrest 2 to switch between the first state and the second state, the headrest 2 is rotated half a circle in the forward direction and then half a circle in the reverse direction, so that the inner sleeve 31 will not be separated from the mounting connecting shaft 6. Such a configuration is convenient for connecting the connecting shaft 6 and the inner sleeve 31 together, and can prevent the fixing sleeve 3 from being separated from the assembly sleeve 11 along the axial direction.
