Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a rotating water outlet structure. Background Technology

[0002] In the bathroom industry, especially with water-spraying devices such as overhead showers and handheld showers, rotating the water spray can achieve better massage and visual effects, meeting the needs of some users.

[0003] In existing technologies, the rotating water output effect in a shower head is generally achieved by multiple rotors installed inside the shower head. This not only has the disadvantages of complex structure and high cost, but also the fact that each rotor rotates independently and cannot be synchronized. This can cause the water jets from different rotor positions to interfere with each other and "fight" each other after being sprayed out, ultimately affecting the massage effect and visual effect, and reducing the shower experience. Utility Model Content

[0004] The purpose of this utility model is to provide a rotating water outlet structure that solves the problems existing in the prior art. It has a simple and easy-to-assemble structure that can achieve the synchronous rotation effect of water splashes from each column without mutual interference.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A rotating water outlet structure includes a main body, an impeller, a sliding plate, and several outlet rods disposed within the main body. The main body has a water passage cavity with several inlet holes and mounting holes, each corresponding to one of the outlet rods. The impeller is driven by water entering through the inlet holes and rotates within the water passage cavity. An eccentric shaft is provided at the end of the impeller facing the outlet rod. The middle section of the outlet rod is dynamically and rotatably fitted within the mounting holes, with an outlet hole between its two ends. The sliding plate is disposed between the impeller and the outlet rods, and has a first shaft hole and several second shaft holes surrounding the first shaft hole. The first shaft hole is located at the center of the sliding plate and is fitted onto the eccentric shaft. The second shaft holes correspond one-to-one with the outlet rods and are fitted onto the inner ends of the corresponding outlet rods.

[0007] The water outlet is located at the axis of the water outlet rod, and the middle section of the water outlet rod has a first spherical surface protruding outwards, while the inner end of the mounting hole has a second spherical surface that allows the first spherical surface to rotate and engage.

[0008] A rotating shaft is provided at the axis of the water passage cavity for the impeller to rotate; the mounting holes are arranged at equal angular intervals around the rotating shaft; the second shaft hole is arranged at equal angular intervals around the axis of the first shaft hole.

[0009] The main body includes an adapter cover, a water guide plate, a water inlet seat, and a water outlet panel; the adapter cover is provided with a connection port and is connected to the water inlet seat; the water guide plate, the water inlet seat, and the water outlet panel form the water passage cavity; the water guide plate is provided with a plurality of water passage holes; the water inlet holes are provided on the circumferential surface of the water inlet seat; and the mounting holes are provided on the water outlet panel.

[0010] Preferably, the bottom of the water inlet seat is provided with a baffle for axially limiting the impeller, and the baffle is provided with a through hole for the eccentric shaft to pass through.

[0011] Preferably, the sliding plate is fitted on the side of the partition plate opposite to the impeller and is provided with a plurality of protrusions abutting against the surface of the partition plate.

[0012] The rotating water outlet structure further includes a flexible sealing element for dynamically sealing the mounting hole; the flexible sealing element is provided with an elastic deformation part for each water outlet rod to pass through, and the elastic deformation part tightly covers the circumferential surface of the water outlet rod.

[0013] Preferably, the elastic deformation portion includes a collar covering the circumferential surface of the water outlet rod, and a connecting ring connecting the circumferential surface of the collar and the flexible seal, the connecting ring having at least one fold.

[0014] Preferably, the rotating water outlet structure further includes a pressure plate installed in the water passage cavity for fixing the periphery of the flexible seal, and the pressure plate is provided with clearance holes at the positions corresponding to the elastic deformation part.

[0015] Preferably, a pressure ring is provided around the relief hole of the pressure plate to abut against the flexible seal.

[0016] After adopting the above technical solution, the present invention has the following technical effects:

[0017] By setting sliding plates between the impeller and each water outlet rod to achieve a linkage relationship, when the impeller rotates due to the water flow from the inlet, it can drive the sliding plates to make circular motion around the axis of the impeller. This causes the second shaft holes on the sliding plates to make circular motion, which in turn drives the water outlet rods through the cooperation between the second shaft holes and the inner ends of the water outlet rods. When the water outlet rods are driven, the middle section is relatively fixed with the mounting hole, while the inner and outer ends make synchronous circular motion, ultimately enabling the water outlets to spray rotating water droplets to achieve a massage effect. Under the synchronous action of the sliding plates, all water outlet rods can achieve synchronous movement and consistent angles, so that the rotating water droplets do not interfere with each other, resulting in a larger water outlet area and better massage and visual effects.

[0029] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0030] refer to Figure 1-3 As shown, this utility model discloses a rotating water outlet structure, including a body 1, and an impeller 2, a sliding plate 3 and several water outlet rods 4 disposed in the body 1;

[0031] The main body 1 is provided with a water passage cavity 11. The water passage cavity 11 is provided with several water inlet holes 12 and mounting holes 13. The mounting holes 13 correspond one-to-one with the water outlet rod 4.

[0032] The impeller 2 is driven to rotate by the water inlet hole 12 and is fitted in the water passage cavity 11. An eccentric shaft 21 is provided at the end of the impeller facing the water outlet rod 4.

[0033] The middle section of the water outlet rod 4 is dynamically sealed and rotatably fitted in the mounting hole 13. A water outlet hole 41 is provided between its two ends so that the water passage cavity 11 can communicate with the outside of the body 1, that is, the water in the water passage cavity 11 can be sprayed out through the water outlet rod 4.

[0034] The sliding plate 3 is disposed between the impeller 2 and the water outlet rod 4, and has a first shaft hole 31 and several second shaft holes 32 surrounding the first shaft hole 31. The first shaft hole 31 is located at the center of the sliding plate 3 and is sleeved on the eccentric shaft 21. The second shaft holes 32 correspond one-to-one with the water outlet rod 4 and are sleeved on the inner end of the corresponding water outlet rod 4.

[0035] Through the above solution, this utility model sets a sliding plate 3 between the impeller 2 and each water outlet rod 4 to achieve a linkage relationship. When the impeller 2 rotates due to the water flow driven by the water inlet hole 12, it can drive the sliding plate 3 to make a circular motion around the axis of the impeller 2, so that each second shaft hole 32 on the sliding plate 3 makes a circular motion. Then, through the cooperation between the second shaft hole 32 and the inner end of the water outlet rod 4, the water outlet rod 4 is driven. When the water outlet rod 4 is driven, its middle section is relatively fixed with the mounting hole 13, and its inner and outer ends make synchronous circular motions. Finally, the water outlet hole 41 can spray rotating water spray to achieve a massage effect. Under the synchronous action of the sliding plate 3, all the water outlet rods 4 can achieve synchronous movement and consistent angle, so that the rotating water sprays will not interfere with each other, the water outlet area is larger, and the massage effect and visual effect are better.

[0036] The following are specific embodiments of the present invention.

[0037] The aforementioned water outlet 41 is located at the axis of the water outlet rod 4, and a first spherical surface 42 protrudes from the middle section of the water outlet rod 4. A second spherical surface 14 is recessed at the inner end of the mounting hole 13 to allow the first spherical surface 42 to rotate and engage. The engagement of the first spherical surface 42 and the second spherical surface 14 guides the movement of the water outlet rod 4; at the same time, the first spherical surface 42 also prevents the water outlet rod 4 from falling out of the mounting hole 13.

[0038] A rotating shaft 5 for the impeller 2 to rotate is provided at the axis of the water passage cavity 11; mounting holes 13 are arranged at equal angular intervals around the rotating shaft 5; and second shaft holes 32 are arranged at equal angular intervals around the axis of the first shaft hole 31.

[0039] The aforementioned main body 1 includes an adapter cover 1a, a water guide plate 1b, a water inlet seat 1c, and a water outlet panel 1d. The adapter cover 1a is provided with a connection port 15 for connecting the rotating water outlet structure to a shower column, water inlet pipe, or other water-supplying bathroom equipment / fittings, and is connected to the water inlet seat 1c. The connection is sealed by a sealing ring 1e. The water guide plate 1b, the water inlet seat 1c, and the water outlet panel 1d form the aforementioned water passage cavity 11. The water guide plate 1b is provided with several water passage holes 16, the water inlet hole 12 is located on the circumferential surface of the water inlet seat 1c, and the mounting hole 13 is located on the water outlet panel 1d. Thus, the main body 1 is designed as multiple parts, which facilitates processing and assembly, resulting in a higher yield rate during production. In this embodiment, the circumferential surface of the connection port 15 is provided with an external thread 17 to facilitate the installation of the rotating water outlet structure by means of a threaded connection.

[0040] Furthermore, the bottom of the aforementioned water inlet seat 1c is provided with a partition 18 for axially limiting the impeller 2, and the partition 18 is provided with a through hole 19 for the eccentric shaft 21 to pass through. Thus, the space between the partition 18 and the water guide plate 1b is the space for the impeller 2 to cooperate, and the space between the partition 18 and the water outlet panel 1 is the space for the sliding plate 3 to cooperate.

[0041] Secondly, the aforementioned sliding plate 3 is fitted onto the side of the partition plate 18 facing away from the impeller 2, and is provided with several protrusions 33 abutting against the surface of the partition plate 18. By providing the protrusions 33, the sliding plate 3 can contact the partition plate 18 to reduce shaking, and at the same time, the protrusions 33 reduce the contact area between the two to reduce friction. In this embodiment, four protrusions 33 are provided at equal angular intervals around the aforementioned second shaft hole 32.

[0042] The present invention also includes a flexible sealing element 6, such as a diaphragm, for the dynamic sealing mounting hole 13; the flexible sealing element 6 is provided with an elastic deformation part 61 for each water outlet rod 4 to pass through, and the elastic deformation part 61 tightly covers the circumferential surface of the water outlet rod 4.

[0043] Furthermore, the aforementioned elastic deformation portion 61 includes a collar 611 covering the periphery of the water outlet rod 4, and a connecting ring 612 connecting the periphery of the collar 611 and the flexible seal 6. The connecting ring 612 has at least one pleat 6121 to achieve adaptive deformation.

[0044] Meanwhile, this utility model also includes a pressure plate 7 installed in the water passage cavity 11 for fixing the periphery of the flexible seal 6. The pressure plate 7 is provided with a relief hole 71 at the position corresponding to the elastic deformation part 61. In this embodiment, a pressure ring 72 is provided around the relief hole 71 of the pressure plate 7 to abut against the flexible seal 6, so as to fix the periphery of each elastic deformation part 61.

[0045] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
