Embodiment 1

Referring to FIGS. 1-13, this embodiment provides a shower, it comprises a top showerhead 1, a shower controller 3 and a height adjustment structure; the height adjustment structure comprises: a movable rod 4, a fixed rod 5 and a damping mechanism 6; and a tail end of the movable rod 4 is connected to the top showerhead 1, and a tail end of the fixed rod 5 is connected to the shower controller 3. In order to transport water to the top showerhead 1, a flow passage in communication with the top showerhead is disposed in the movable rod 4; and specifically, a hollow portion used as the flow passage is formed in the movable rod 4 by extending along a length direction. The hollow portion can also provide an avoidance space for a relative movement of the movable rod and the fixed rod in addition to serving as the flow passage for transporting the water.
A bottom of the movable rod 4 is sleeved on a top of the fixed rod 5, and the damping mechanism 6 is disposed on a connection position of the movable rod 4 and the fixed rod 5 and is fixedly connected to the movable rod 4; and in this way, the damping mechanism 6 moves to drive the movable rod 4 to move together relative to the fixed rod 5.
In this embodiment, a friction force between the damping mechanism 6 and the fixed rod 5 is changed by the damping mechanism 6 under an external force, so as to unlock the movable rod 4 and the fixed rod 5 through the damping mechanism 6. After an adjustment is complete, as long as the external force is removed, the movable rod 4 and the fixed rod 5 can be locked through the damping mechanism 6 so as to fix positions of the movable rod 4 and the fixed rod 5, and the adjustment in height is complete. In the height adjustment structure, the movable rod 4 is sleeved outside of the fixed rod 5, the damping mechanism 6 is disposed on a lower end of the movable rod 4, and the user can switch the damping mechanism 6 to an unlocked state by operating the damping mechanism 6. As the damping mechanism 6 is fixed on the movable rod 4, the user can directly move the movable rod 4 by holding the damping mechanism 6 after the operation of unlocking. Therefore, the whole adjustment process is relatively simple. That is, the damping mechanism 6 can directly move without an operation of other positions after the user unlocks the damping mechanism 6, which is very convenient.
Specifically, the damping mechanism 6 comprises an operating member in a seesaw structure, one end of the operating member corresponding to the movable rod 4 is connected to a preload spring 61, and one end of the operating member corresponding to the fixed rod 5 is disposed with a friction pad 62;
When the damping mechanism 6 is not subjected to an external force, the operating member drives the friction pad 62 to swing toward a direction adjacent to the fixed rod 5 under an action of the preload spring 61, so that the damping mechanism 6 and the fixed rod 5 are locked by increasing a friction force between the friction pad 62 and the fixed rod 5; and when the damping mechanism 6 is subjected to an external force, the operating member overcomes a force of the preload spring 61 to drive the friction pad 62 to swing in a direction away from the fixed rod 5 under the external force, so that the damping mechanism 6 and the fixed rod 5 are unlocked by reducing the friction force between the friction pad 62 and the fixed rod 5.
Therefore, in order to realize an installation of the seesaw structure, the damping mechanism 6 comprises a body 63 sleeved on a connection position of the movable rod 4 and the fixed rod 5; an avoidance chamber 631 configured for a movement of the friction pad 62 runs through a position of the body 63 corresponds to the friction pad 62 along a radial direction of the body 63, so that there is a space allowing the friction pad 62 to swing accordingly when the operating member swings. In addition, the operating member comprises a button 64 and a rotating shaft assembly 65; and a side of the body 63 facing outward is disposed with a first mounting member 632 for mounting the rotating shaft assembly 65 and a second mounting member 633 for connecting the preload spring 61. The seesaw structure can be formed by the button 64 and a rotating shaft 652, and one end of the button 64 is pressed to compress the spring so as to enable the friction pad 62 on the other end to swing in the direction away from the fixed rod 5. After releasing the button 64, the preload spring 61 releases an elastic restore force, allowing the friction pad 62 on the other end to swing in the direction adjacent to the fixed rod 5.
In order to install the rotating shaft 652, the rotating shaft assembly 65 comprises a mounting matching member 651 for matching with the first mounting member 632 and the rotating shaft 652; and the rotating shaft 652 is connected to the mounting mating member 651 and extends into the avoidance chamber 631. The first mounting member 632 and the mounting matching member 651 described in this embodiment are respectively a mounting hole and an avoidance hole, and a bolt passes through the avoidance hole and the mounting hole to be fixedly installed so as to enable the rotating shaft 652 to be fixed to the body 63.
In the shower, in order to prevent the movable rod 4 from being washed away by the water flow, a constant pressure valve 2 is disposed on a connecting end of the fixed rod 5 and the shower controller 3 to regulate a water inflow pressure at a predetermined value; and the predetermined value in this embodiment is 2 Kg or 0.2 Mpa. In actual use, this predetermined value can be adjusted according to a weight of the movable rod 4 and the top showerhead 1.

Embodiment 2

Referring to FIGS. 14 and 15, the damping mechanism 6 in this embodiment comprises a first part 66 fixed to the movable rod 4 and a second part 67 sleeved on the fixed rod 5;
An inner wall of one side of the second part 67 is connected to the fixed rod 5 through the friction pad 62 and the preload spring 61, and a gap 671 is disposed between an inner wall of the other side and the fixed rod 5 to form a space configured to allow the second part 67 to move radially.
In this way, when the user presses the damping mechanism 6, the damping mechanism 6 will move in the space, so that the friction pad 62 moves in the direction away from the fixed rod 5, thereby reducing the friction force between the friction pad 62 and the fixed rod 5 and switching to the unlocked state. At this time, the preload spring 61 is stretched to accumulate the restore force, once the user releases the damping mechanism 6, the restore force of the preload spring 61 will drive the friction pad 62 to move as well in the direction adjacent to the fixed rod 5, thereby enabling the damping mechanism 6 to return to the locked state again by increasing the friction force between the friction pad 62 and the fixed rod 5.
Specifically, the damping mechanism 6 comprises the body 63 sleeved on the connection position of the movable rod 4 and the fixed rod 5, and the body 63 is fixedly connected to the movable rod 4; it further comprises a button 68 disposed in the body 63, the body 63 comprises a mounting chamber for accommodating the button 68, and one side of the mounting chamber along a radial direction is an opening surface for exposing the button 68 to form an operating surface. The gap 671 is formed between the operating surface and the fixed rod 5; a side of the button 68 away from the operating surface comprises an opening for installing the friction pad 62 and a convex column for connecting the preload spring 61; the preload spring 61 is connected to and disposed between an inner side wall of the button 68 and an outer wall of the mounting chamber; and the friction pad 62 is connected to and disposed between the inner side wall of the button 68 and an outer wall of the fixed rod 5.

Embodiment 3

In addition, the abutting member 60 comprises a set screw 601, a spring 602 and a preload pin 603; the set screw 601 is connected to the preload pin 603 through the spring 602, and the preload pin 603 abuts the bushing 69. Therefore, the user can change a force of the set screw 601 applied to the preload pin 603 by rotating the set screw 601, thereby changing a friction force between the bushing 69 and the fixed rod 5 by changing a force between the preload pin 603 and the bushing 69, so as to achieve unlocking and locking of the damping mechanism 6.
In order to adjust the friction force between the movable rod and the fixed rod to ensure the friction force provided thereof to be greater than gravity applied to the movable rod and the top showerhead and other water outflow terminals connected thereto, so as to stay at any position within the adjustable range.
In the solution of this embodiment, during an installation process, the force of the set screw 601 applied to the preload pin 603 is changed by rotating the set screw 601, after adjusting to a suitable friction force, and a relative position of the movable rod 4 and the fixed rod 5 can be directly adjusted after overcoming the friction force without adjusting the set screw 601 again. Therefore, compared with the solutions of Embodiments 1 and 2, this embodiment simplifies the unlocking step.
