[0002] The existing shower includes an overhead shower head, a hand-held shower head and a vertical rod. The overhead shower head and the hand-held shower head are both mounted on the vertical rod and mounted on the wall through the vertical rod. Among them, the overhead shower head is a fixed overhead shower head, and the installation height of the fixed overhead shower head is fixed. Therefore, during the installation process, the height cannot be adjusted accordingly according to the height of the room, which leads to inconvenience in installation; and when in use, the overhead shower head cannot be adjusted accordingly according to the different heights of users to make the overhead shower head reach the most suitable height.

One end of the movable rod is movably connected to the fixed rod, and the other end of the movable rod is connected to the top spray shower body. The movable rod drives the top spray shower body to move up and down relative to the fixed rod; one end of the water pipe assembly is arranged in the fixed rod, and the other end of the water pipe assembly is passed through the fixed rod and the movable rod, and is connected to the top spray shower body; the fastener is passed through the fixed rod and abuts against the outer peripheral wall of the movable rod to lock or loosen the movable rod to the fixed rod, and the movable rod moves up and down in the fixed rod, and the water pipe assembly moves with the movement of the movable rod, so that the installation height of the top spray shower body can be arbitrarily adjusted within a certain range, thereby meeting more usage scenarios.

[0004] However, the above technical solution still has the problem of inconvenient adjustment. For example, the fastener passes through the fixed rod, so the fastener needs to be removed before the movable rod can be moved, which makes it difficult for users to complete the above operation.

[0050] Example 1

[0051] refer to Figure 1-Figure 13 This embodiment provides a shower, including a top spray head 1, a shower controller 3 and a height adjustment structure; the height adjustment structure includes: a movable rod 4, a fixed rod 5 and a damping mechanism 6; the end of the movable rod 4 is connected to the top spray head 1, and the end of the fixed rod 5 is connected to the shower controller 3. In order to transport water to the top spray head 1, a flow channel connected to the top spray head is provided in the movable rod 4; specifically, a hollow portion is formed in the movable rod 4 along the length direction as the flow channel. In addition to serving as a flow channel for transporting water, the hollow portion can also provide a clearance space for the relative movement of the movable rod and the fixed rod.

[0052] The bottom of the movable rod 4 is sleeved outside the top of the movable rod fixed rod 5, and the damping mechanism 6 is arranged at the connection between the movable rod 4 and the fixed rod 5, and is fixedly connected to the movable rod 4; in this way, the movable rod 4 can be driven to move relative to the fixed rod 5 by moving the damping mechanism 6.

[0053] In this embodiment, the damping mechanism 6 changes the friction between the damping mechanism 6 and the fixed rod 5 under the action of an external force, so as to unlock the movable rod 4 and the fixed rod 5 through the damping mechanism 6. After the adjustment is completed, 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 that the positions of the movable rod 4 and the fixed rod 5 are fixed and the height adjustment is completed. In the above-mentioned height adjustment structure, the movable rod 4 is sleeved outside the fixed rod 5, and the damping mechanism 6 is provided at the lower end of the movable rod 4. The user can switch the damping mechanism 6 to the unlocked state by operating the damping mechanism 6. Since the damping mechanism 6 is fixed on the movable rod 4, after the unlocking operation, the user can directly move the movable rod 4 by holding the damping mechanism 6. Therefore, the whole adjustment process is relatively simple. That is to say, after the user unlocks the damping mechanism 6, the damping mechanism 6 can be directly moved without operating other positions, which is very convenient.

[0054] Specifically, the damping mechanism 6 includes 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 provided with a friction pad 62;

[0055] When the damping mechanism 6 is not subjected to external force, the operating member drives the friction pad 62 to swing in the direction close to the fixed rod 5 under the action of the preload spring 61, thereby increasing the friction between the friction pad 62 and the fixed rod 5, and locking the damping mechanism 6 and the fixed rod 5; when the damping mechanism 6 is subjected to external force, the operating member overcomes the force of the preload spring 61 under the action of the external force and drives the friction pad 62 to swing in the direction away from the fixed rod 5, thereby reducing the friction between the friction pad 62 and the fixed rod 5, and unlocking the damping mechanism 6 and the fixed rod 5.

[0056] Therefore, to realize the installation of the seesaw structure, the damping mechanism 6 includes a body 63 provided at the connection between the movable rod 4 and the fixed rod 5; the body 63 is provided with a clearance cavity 631 for the friction pad 62 to move along the radial direction of the body 63 corresponding to the position of the friction pad 62, so that the friction pad 62 can have space to swing with it when the operating member swings. And the operating member includes a button 64 and a rotating shaft assembly 65; the body 63 is provided 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 on the outward side. The seesaw structure can be formed by the button 64 and the rotating shaft 652. Pressing one end of the button 64 to compress the spring can make the friction pad 62 at the other end swing in the direction away from the fixed rod 5. After releasing the button 64, the preload spring 61 releases the elastic reset force, so that the friction pad 62 at the other end swings in the direction close to the fixed rod 5.

[0057] In order to install the rotating shaft 652, the rotating shaft assembly 65 includes a mounting fitting 651 for matching with the first mounting member 632 and a rotating shaft 652; the rotating shaft 652 is connected to the mounting fitting 651 and extends into the clearance cavity 631. The first mounting member 632 and the mounting fitting 651 described in this embodiment are respectively a mounting hole and a clearance hole, and the rotating shaft 652 can be fixed to the body 63 by passing bolts through the clearance hole and the mounting hole for fixing.

[0058] In order to prevent the movable rod 4 from being washed out by the water flow, a constant pressure valve 2 is provided at the connection end of the fixed rod 5 and the shower controller 3 to stabilize the water inlet pressure at a set value; the set value in this embodiment is 2kg. In actual use, this set value can be adjusted according to the weight of the movable rod 4 and the overhead shower head 1.

[0059] Example 2

[0060] refer to Figure 14-15 , the damping mechanism 6 in this embodiment includes a first portion 66 fixed on the movable rod 4, and a second portion 67 sleeved on the fixed rod 5;

[0061] One inner wall of the second part 67 is connected to the fixing rod 5 via a friction pad 62 and a preload spring 61 , and a gap 671 is provided between the other inner wall and the fixing rod 5 to form a space for the second part 67 to move in the radial direction.

[0062] In this way, when the user presses the damping mechanism 6, the damping mechanism 6 will move in the above-mentioned space, so that the friction pad 62 moves in the direction away from the fixed rod 5, so that the friction between the friction pad 62 and the fixed rod 5 becomes smaller, and the state is switched to the unlocked state. At this time, the preload spring 61 is stretched to accumulate the reset force. Once the user releases the damping mechanism 6, the reset force of the preload spring 61 will drive the friction pad 62 to move in the direction close to the fixed rod 5, increase the friction between the friction pad 62 and the fixed rod 5, and return the damping mechanism 6 to the locked state.

[0063] Specifically, the damping mechanism 6 includes a body 63 sleeved at the connection between the movable rod 4 and the fixed rod 5, and the body 63 is fixedly connected to the movable rod 4; it also includes a button 68 arranged in the body 63, and the body 63 is provided with a mounting cavity for accommodating the button 68, and one side of the mounting cavity along the radial direction is an open 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; the side of the button 68 away from the operating surface is provided with an opening for installing the friction pad 62 and a protrusion for connecting the preload spring 61; the preload spring 61 is connected between the inner side wall of the button 68 and the outer wall of the mounting cavity; the friction pad 62 is connected between the inner side wall of the button 68 and the outer wall of the fixed rod 5.

[0064] Example 3

[0065] refer to Figure 16-Figure 17 The damping mechanism 6 includes a main body 63 which is sleeved at the connection between the movable rod 4 and the fixed rod 5. The part of the main body 63 corresponding to the movable rod 4 is fixedly connected to the movable rod 4. A bushing 69 is arranged in the part of the main body 63 corresponding to the fixed rod 5. The side wall of the main body 63 is provided with an abutment member 60 for abutting the bushing 69.

[0066] Furthermore, the abutment member 60 includes a set screw 601, a spring 602 and a pre-tightening pin 603; the set screw 601 is connected to the pre-tightening pin 603 via the spring 602, and the pre-tightening pin 603 abuts against the bushing 69. Therefore, the user can change the force of the set screw 601 on the pre-tightening pin 603 by rotating the set screw 601, thereby changing the force between the pre-tightening pin 603 and the bushing 69, and changing the friction between the bushing 69 and the fixing rod 5, so as to achieve unlocking and locking of the damping mechanism 6.

[0067] To adjust the friction between the movable rod and the fixed rod, ensure that the friction provided is greater than the gravity of the movable rod and the top spray and other water outlet terminals connected thereto, so that it can stay at any position within the adjustable range.

[0068] In the solution of this embodiment, during the installation process, the force of the set screw 601 on the pre-tightening pin 603 is changed by rotating the set screw 601. After adjusting it to a suitable friction force, there is no need to adjust the set screw 601 again. The relative position of the movable rod 4 and the fixed rod 5 can be adjusted directly after overcoming the friction force. Therefore, compared with the solutions of embodiments 1 and 2, this embodiment simplifies the unlocking step.

[0069] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
