Description

Technical Field

[0001] The utility model relates to the technical field of showers, in particular to a height-adjustable side water outlet structure and a shower. Background Art

[0002] A side-outlet showerhead is a showerhead that installs a water outlet on the side of a shower column and sprays the user's body with water from the side. The water outlet of this type of showerhead is designed to slide up and down on the side of the shower column so that the height of the water outlet can be adjusted at will to meet the showering needs of users of different heights. Since the water inlet method of the showerhead is parallel to the setting direction of the shower column, that is, the water inlet is in the up and down direction, and the height adjustment of the water outlet is also in the up and down direction, the water outlet is inevitably affected by the force of water pressure during the up and down sliding process. In the early days of the industry, the side-outlet showerhead could not achieve water pressure balance inside, so when the user adjusted the height of the water outlet, it was necessary to overcome the water pressure, which required a large force and made the adjustment feel poor.

[0003] In the prior art, for example, Patent CN220058202U discloses a "Shower rod and shower assembly with height-adjustable side water outlet function". Its specific implementation method discloses that a hydraulic balance structure is provided in the shower rod, so that the user does not need to overcome water pressure when moving the side water outlet assembly. Specifically, the hydraulic balance structure includes an inner tube fixedly connected to the shower rod, and an outer tube sleeved on the inner tube, and the side water outlet assembly is connected and communicated with the outer tube; the inner tube has a first water path, and the inner tube and the outer tube have a second water path between them. The first water path is communicated with the second water path through a water hole, and the upper end and the lower end of the outer tube are respectively sealed and connected to the side wall of the inner tube through a plug. Therefore, the area of ​​the plugs at the upper and lower ends of the outer tube exposed between the inner tube and the outer tube is designed to be equal. After the water is passed, when the water flows into the second waterway, the water pressure forces on the upper and lower ends of the outer tube can be equal in magnitude and opposite in direction, so that the outer tube is in a state of water pressure balance. The user does not need to overcome the force of water pressure when moving the outer tube up and down through the side water outlet assembly, thereby saving effort.

[0004] The defect of the above patent is that the second water path between the inner tube and the outer tube is sealed by plugs at the upper and lower ends of the outer tube, and both ends of the outer tube can only move within the corresponding ends of the inner tube and cannot be separated from the circumference of the inner tube, otherwise it will cause water leakage. In this patent, the movement stroke of the outer tube (that is, the side water outlet component) is limited by the length of the inner tube and the position of the water hole on the inner tube, and the maximum can only reach nearly 1 / 2 of the length of the inner tube, and the adjustment stroke is small.

[0035] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0037] The fixed pipe 1 is provided with a first water channel 1a and a second water channel 1b in the up-down direction. The lower ends of the first water channel 1a and the second water channel 1b are connected to the same water inlet end (such as the water inlet device 5 described below), and the upper end of the first water channel 1a is open, and the upper end of the second water channel 1b is closed; a water hole 121 is provided on the side of the second water channel 1b;

[0038] The lifting pipe 2 is provided with an active channel 2a, and a water outlet channel 2b is provided on the side of the active channel 2a. The water outlet channel 2b is connected to the water outlet device 6 of the shower, so that the water outlet device 6 and the lifting pipe 2 are kept in synchronous lifting, and the height adjustment can be performed synchronously with the lifting pipe 2 in the subsequent structure; the active channel 2a is sleeved on the circumference of the fixed pipe 1, and the outer wall of the fixed pipe 1 is provided with a first convex ring 111 that can seal the inner wall of the active channel 2a, and the inner wall of the active channel 2a is provided with a movable sealing outer wall of the middle pipe 2. The second convex ring 2211 of the inner tube 1 and the outer wall of the fixed tube 1, the first convex ring 111, the inner wall of the movable channel 2a and the second convex ring 2211 form a third water path 1c (which is realized by adjusting the height of the lifting tube 2). The third water path 1c is connected to the water outlet channel 2b and is connected to the second water path 1b through the water hole 121, so that the second water path 1b can be connected to the water outlet channel 2b. The water flowing into the inner tube 1 and the middle tube 2 will flow to the water outlet device 6 through the water hole 121, the third water path 1c and the water outlet channel 2b.

[0039] The balancing rod 3 is relatively fixedly arranged in the movable channel 2a, and its lower end is movably and sealingly penetrated into the upper end of the first waterway 1a; the area of ​​the balancing rod 3 exposed in the first waterway 1a is equal to the area of ​​the second convex ring 2211 exposed in the third waterway 1c (this is a preferred embodiment, which realizes complete balance of water pressure. When there is a slight difference in the areas of the two, the force applied to the lifting pipe 2 during the lifting and lowering process will be different. It will save a little effort when it is in the same direction as the direction with greater water pressure, and it will be slightly more laborious when it is in the opposite direction).

[0040] Through the above scheme, the utility model sets a first water channel 1a and a second water channel 1b in the fixed pipe 1, and the two are connected to the same water inlet end and are independent of each other, so that the first water channel 1a and the second water channel 1b have the same water pressure, and at the same time the lifting pipe 2 is movably sleeved on the circumference of the fixed pipe 1, so that the third water channel 1c is between the two, and the third water channel 1c is connected with the second water channel 1b; because the fixed pipe 1 is in a fixed state after the product is installed, the position remains unchanged, and the force of the water pressure on the first convex ring 111 is offset by the limiting force of the installation of the fixed pipe 1, and when the lifting pipe 2 moves up and down relative to the fixed pipe 1, the water pressure forces on the balance rod 3 and the second convex ring 2211 are opposite, and the exposed areas of the two are designed to be equal, so that the water pressure forces on the lifting pipe 2 can be equal, and the water pressure balance can be achieved, and the user does not need to overcome the water pressure when adjusting the height of the lifting pipe 2. force, realizing labor-saving operation; since the balancing rod 3 is always movably sealed in the first water channel 1a, the third water channel 1c relies on the first convex ring 111 located on the fixed pipe 1 and the second convex ring 2211 located on the lifting pipe 2 to realize active sealing. As long as the first convex ring 111 and the water hole 121 are designed near the upper end of the fixed pipe 1 and the second convex ring 2211 is designed near the lower end of the movable channel 2a, the stroke of the lifting pipe 2 can be close to the length of the fixed pipe 1. Compared with the existing patent, which can only achieve a maximum of nearly 1 / 2 of the inner pipe length, when the length of the fixed pipe 1 is the same as that of the inner pipe of the existing patent, a larger adjustment stroke of nearly 2 times can be achieved, so as to meet the needs of product design; in addition, when the height is not adjusted, the shower mainly relies on the friction force of the active seals between the accessories to offset the overall gravity of the lifting pipe 1 and the water outlet device 6.
