Description

Technical Field

[0001] This invention relates to a shower, and more particularly to a lift-up shower. Background Technology

[0002] Existing shower technologies include shower columns, slides, handheld shower heads, and overhead shower heads. The lower end of the shower column is connected to the shower faucet, and the upper end is connected to the overhead shower head. The slide is clamped to the shower column by a clamping mechanism and also includes a socket for inserting the handheld shower head, the lower end of which can be inserted into the socket. In some existing shower technologies, the height of the overhead shower head is fixed; that is, the overhead shower head is directly fixed to the top of the shower column, and the angle of the water flow can only be adjusted, not according to the user's height. In other shower technologies, although the height of the overhead shower head is adjustable, the adjustment structure is cumbersome: the overhead shower head is connected to a water inlet pipe, which is slidably connected to the shower column via a plug-in connection. After adjusting to the desired height, the water inlet pipe and the shower column are then fixed together by corresponding fastening components (e.g., screws). This adjustment method is not only structurally complex and cumbersome to adjust, but also provides a poor feel. Summary of the Invention

[0019] The two fixing plates slide on the two side walls of the supporting fixing tube respectively; the operating component connects and fixes the two fixing plates.

[0020] In a preferred embodiment, the support fixing tube includes a side groove;

[0021] The water-passing component includes a water-passing body located above the movable water outlet, and the water-passing body is slidably disposed within the support and fixing pipe;

[0032] The movable water outlet includes a housing, and the water-passing component is disposed within the housing. The housing is at least partially sleeved and slidable outside the supporting and fixing pipe. The housing includes a fixing plate. The housing also includes an arm, one end of which is fixedly connected to the upper end of the fixing plate, and the other end of which is fixedly connected to the water outlet device. Compared to an L-shaped arm, the arm is shorter, resulting in less force on the water-passing body during lifting and lowering, stable lifting, and less swaying. The fixing plate reduces swaying and simplifies the structure of the movable water outlet.

[0033] The coil spring at least partially counteracts the weight of the water outlet component, allowing the movable water outlet to slide along the height direction. The weight of the movable water outlet is effectively counteracted, providing a better feel and eliminating the need for additional fixing components to achieve height positioning of the water outlet device. This makes lifting and lowering effortless and convenient. During lifting and lowering adjustment, the slider or the water-passing body pushes the coil spring to flatten. When the coil spring is flattened and stretched, its outer diameter decreases. Unaffected by the decrease in outer diameter during flattening, the linear motion of the slider is kept constant by the direction of the coil spring force, resulting in relatively stable lifting and lowering motion. During contraction, the coil spring curls back to its original position due to internal pressure. Attached Figure Description

[0046] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] See Figures 1-12 A shower includes a support and fixing pipe 1, a force balancing mechanism 2, and a movable water outlet 3.

[0048] The supporting pipe 1 includes a supporting pipe 11 and an inner water inlet pipe 12. The supporting pipe 11 is cylindrical and fixedly installed on the wall. The inner water inlet pipe 12 is arranged inside the supporting pipe 11, with its upper end connected to the upper end of the supporting pipe 11 and its lower end extending out of the lower end of the supporting pipe 11 and communicating with an external water source. In this embodiment, the lower end of the supporting pipe 11 is mounted on a shower faucet, and the inner water inlet pipe 12 is connected to the shower faucet. In this embodiment, the supporting pipe 11 has a square cross-section, and its inward-facing side abuts against the wall.

[0049] The lower part of the movable water outlet section 3 is provided with an operating component 31, which is used to be pulled by an external force to drive the movable water outlet section 3 to move up and down. The upper part of the movable water outlet section 3 is provided with a water outlet device 32, which can be a top spray shower or a side spray shower. The movable water outlet section 3 includes a water passage connecting the water outlet device 32, which is connected to the water inlet pipe 12. The movable water outlet section 3 is configured to move on the supporting fixed pipe 1 at least along the height direction. The force balancing mechanism 2 is connected between the supporting fixed pipe 1 and the movable water outlet section 3, and the force balancing mechanism 2 is configured to at least partially offset the gravity of the movable water outlet section 3. In some preferred embodiments, the force balancing mechanism 2 offsets the gravity of the movable water outlet section 3, so that the movable water outlet section 3 is in a force balanced state. A guide wheel mechanism 4 is provided between the movable water outlet section 3 and the supporting fixed pipe 1, and the movable water outlet section 3 is movably connected to the supporting fixed pipe 1 through the guide wheel mechanism 4. The operating component 3 is fixedly sleeved on the outside of the lower end of the fixed plate 341, and slides relative to the supporting fixed tube 1 together with the fixed plate 341.

[0050] When it is necessary to adjust the height of the movable water outlet 3, it is only necessary to move the operating component 31 up and down. Since the force balancing mechanism 2 balances and counteracts the gravity of the movable water outlet 3, after the adjustment is completed, the movable water outlet 3 is back to the force balance state, that is, in a static state. The guide wheel mechanism 4 can reduce the frictional force when the movable water outlet 3 moves relative to the supporting fixed pipe 1. Since the guide wheel mechanism 4 uses rolling friction when the movable water outlet 3 or the supporting fixed pipe 1 moves relative to each other, and static friction is generated between the water outlet and the movable water outlet 3 when the relative movement stops, the feel is better.

[0051] In this embodiment, the force balancing mechanism 2 is connected between the lower part of the movable water outlet section 3 and the support fixing pipe 1; the guide wheel mechanism 4 is disposed on the upper part of the movable water outlet section 3. The force balancing mechanism 2 is a coil spring 21, one end of which is connected to the support fixing pipe 1, and the other end of which is connected to the movable water outlet section 3.

[0052] Specifically, the coil spring 21 includes a coiled steel sheet 23, the end of which is connected to the support and fixing tube 1. In this embodiment, the end of the steel sheet 23 is fixedly connected to a fixing base 24, which is then fixedly connected to the support and fixing tube 1. The movable water outlet 3 is connected to the coiled portion of the steel sheet 23. In some simpler alternatives, the end of the steel sheet 23 can also be directly connected to the support and fixing tube 1, or the end of the steel sheet 23 can be connected to both the fixing base 24 and the support and fixing tube 1. The key is that the end of the steel sheet 23 can remain relatively fixed and stationary with respect to the support and fixing tube 1.

[0053] In this embodiment, the coil spring 21 is a constant-force coil spring. In this embodiment, the fixed base 24 is fixedly connected to the support tube 11. The force balancing mechanism 2 includes two coil springs 21 connected to the movable water outlet 3. When the movable water outlet 3 moves relative to the support tube 1, the rotation will move closer to or further away from the fixed base 24. Since the coil spring 21 can provide a constant tension force, the direction of this tension force extends along the stretching direction. In this embodiment, the support tube 11 is arranged vertically. The movable water outlet 3 moves up and down vertically relative to the support tube 11 of the support tube 1. The stretching direction of the coil spring 21 extends along the vertical direction. The constant tension force generated by the coil spring 21 can counteract the weight of the entire movable water outlet 3. Therefore, when the user pulls the operating component 31 to move the movable water outlet 3, the resistance felt is very small, and after stopping pulling, the movable water outlet 3 can stop at the corresponding position, realizing the height adjustment of the movable water outlet 3.

[0054] In this embodiment, the movable water outlet 3 includes a housing 34 and a water-passing component 35 disposed within the housing 34. The housing 34 is at least partially sleeved on the outside of the supporting and fixing pipe 1, and the housing 34 and the supporting and fixing pipe 1 form a slider-groove mechanism to limit the range of motion of the movable water outlet 3. The water-passing component 35 includes a water-passing body 351 located at the upper part of the movable water outlet 3, and a guide wheel mechanism 4 is disposed on the water-passing body 351. When the movable water outlet 3 moves relative to the supporting and fixing pipe 1, the guide wheel mechanism 4 rolls against the inner wall of the supporting and fixing pipe 1.

[0055] The outer casing 34 includes two fixing plates 341. The fixing plates 341 correspond to the outer edges of the two side walls 111 of the support tube 11 and slide relative to the two side walls 111. The side walls 111 of the support tube 11 form vertically extending side slots 112. A protrusion extending into the side slot 112 is provided on the fixing plate 341, and the protrusion and the side slot 112 form the slider-groove mechanism. In this embodiment, the side walls 111 of the support tube 11 match the shape of the fixing plates 341. In this embodiment, the guide wheel mechanism 4 includes multiple guide wheels disposed on the water-passing body 351, and the wheel bodies of the guide wheels elastically abut against the support fixing tube 1. In this embodiment, the water-passing component 35 further includes a water inlet pipe 352 and a slider 353. The upper end of the water inlet pipe 352 is connected to the water-passing body 351, and the lower end of the water inlet pipe 352 is connected to the slider 353. The slider 353 is connected to the force balancing mechanism 2. Specifically, a square groove 3531 is formed on the lower side of the slider 353, and the curled part of the steel sheet 23 rotates within the square groove 3531. The curled part of the steel sheet is hollow. A sliding hole 241 is formed on the fixed base 24, through which the water inlet pipe 352 passes and slides on the sliding hole 241. The water inlet pipe 352 is sleeved on the outside of the inner water inlet pipe 12, and the side wall 111 of the inner water inlet pipe 12 includes a through hole 121 for connecting the water inlet pipe 352. The inner inlet pipe 12 is connected to the inlet pipe 352 through the through hole 121. Warm water from the shower faucet enters the inlet pipe 352 through the through hole 121 of the inner inlet pipe 12, and then enters the water-passing body 351 through the inlet pipe 352. The water-passing body 351 is connected to the water outlet device 32 to allow water to flow from the water outlet device 32. In some simpler alternatives, the water-passing body 351 is connected to the force balancing mechanism 2. Specifically, the square groove 3531 is formed on the water-passing body 351, and the curled portion of the steel sheet 23 rotates within the square groove 3531 of the water-passing body 351. The curled portion of the steel sheet 23 is gradually flattened by the push of the slider 353 or the water-passing body 351. When the curled portion of the steel sheet 23 is flattened and stretched, the outer diameter of the curled portion shrinks. Since the curled portion is located in the square groove 3531, it is not affected by the shrinkage of the outer diameter of the spring when it is flattened. The linear motion of the slider or the water-passing body is constant due to the direction of the spring force, and the lifting motion is relatively stable. During the contraction motion, the curled portion is curled back to its original position by internal pressure.

[0056] The water-passing body 351 includes a water-passing chamber 3511 connected to the water inlet pipe 352. The upper pressure-bearing area and the lower pressure-bearing area of ​​the water-passing chamber 3511 are equal. Therefore, the water pressure in the water-passing body 351 will not affect the overall moving water outlet part 3.

[0057] The outer casing 34 also includes an arm 343, one end of which is fixedly connected to the upper end of the fixing plate 341, and the other end of which is fixedly connected to the water outlet device 32. Compared to the L-shaped arm, the arm 343 is shorter, resulting in less force on the water-passing body 351 when it is raised or lowered, making the raising and lowering stable and less prone to shaking.

[0058] The water-passing body 351 is slidably disposed within the supporting and fixing pipe 1; the water-passing component 35 further includes a water-passing connecting seat 354, which connects the water outlet device 32 and the water-passing body 351. The water-passing body 351 includes a side outlet 3512, and the water-passing connecting seat 354 includes a first water-passing column 3541 inserted into the side outlet 3512. The first water-passing column 3541 is in fluid communication with the water-passing body 351 and the water outlet device 32. The first water-passing column 3541 passes through the side slot 112 and is slidably disposed within the side slot 112 to limit the range of motion of the movable water outlet part 3. In this embodiment, the first water-passing column 3541 forms the protrusion. The water-passing body 351 includes two side water outlets 3512, which are located on both sides of the water-passing body 351. The water-passing connecting seat 354 includes two first water-passing columns 3541, which pass through two side slots 112 to be inserted into the two side water outlets 3512.

[0059] The support arm 343 is provided with a branch passage 3431 for fluid connection to the overhead shower head 32, and the water-passing connector 354 is connected between the branch passage 3431 and the water-passing body 351. The water-passing connector 354 includes two second water-passing columns 3542, which are respectively connected to the branch passage 3431.

[0060] The fixing plate 341 includes guide posts 3411 extending along the moving direction of the movable water outlet 3, and the two side walls 111 of the supporting fixing pipe 1 include guide sleeves 113 extending along the moving direction of the movable water outlet 3; the guide posts 3411 are slidably disposed within the guide sleeves 113. This enhances the deformation resistance of the fixing plate 341, thereby improving stability, and the guide sleeves 113 also make the guiding sliding of the fixing plate 341 smoother. In this embodiment, the opening of the guide sleeve faces the rear side of the shower, resulting in good consistency and a clean and aesthetically pleasing appearance.

[0061] By applying this technical solution, the force balancing mechanism 2 cancels out the gravity of the water outlet component. Therefore, the movable water outlet part 3 can slide along the height direction and is fixed by the guide wheel mechanism 4 between it and the support fixing pipe 1. The user can directly grasp the operating part 31 on the movable water outlet part 3 to drive the movable water outlet part 3 to move up and down to adjust the height of the water outlet device 32. The gravity of the movable water outlet part 3 is canceled out, and it moves through the guide wheel mechanism 4, so that the friction of the movable water outlet part 3 when it moves is small, the feel is good, and no additional fixing and positioning parts are needed to achieve the height positioning of the water outlet device 32.

[0062] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
