Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bathroom facilities, and particularly refers to a rotating water spraying structure.
Background Art
[0002] In the field of bathroom facilities, particularly in water supply appliances such as overhead showers and hand showers, a better massage effect and visual effect can be achieved by the rotating water spray of the water, which can meet the needs of some users.
[0003] According to the prior art, the rotating water spraying effect in a shower head is generally realized by a plurality of rotors installed in the shower head. However, there are disadvantages such as a complex structure and high cost. In addition, since each rotor rotates independently, simultaneous rotation cannot be achieved. When water sprays out from the positions of each rotor, multiple water sprays interfere with each other, and there is a possibility of "colliding", which ultimately affects the massage effect and visual effect and reduces the quality of the shower experience.

Modes for Carrying Out the Invention
[0017] To further explain the technical means of the present invention, the present invention will be described in detail below with specific embodiments.
[0018] Referring to FIGS. 1 to 3, the present invention discloses a rotary water spraying structure, which includes a main body 1, an impeller 2 installed in the main body 1, a slide piece 3, and a plurality of water spraying rods 4. A water passage chamber 11 is provided in the main body 1, and a plurality of water supply holes 12 and mounting holes 13 are provided in the water passage chamber 11. The mounting holes 13 correspond one-to-one to the water spraying rods 4. The impeller 2 is fitted into the water passage chamber 11 so as to be driven by the water supply from the water supply holes 12 to rotate, and an eccentric shaft 21 is installed at the end thereof facing the water spraying rod 4. The water spraying rod 4 is rotatably fitted into the mounting hole 13 with its middle part sealed by a dynamic seal, and a water spraying hole 41 is provided between its both ends to communicate the water passage chamber 11 with the outside of the main body 1, that is, the water in the water passage chamber 11 can be ejected through the water spraying rod 4. The slide piece 3 is installed between the impeller 2 and the water spraying rod 4, and a first shaft hole 31 and a plurality of second shaft holes 32 surrounding the first shaft hole 31 are provided thereon. The first shaft hole 31 is arranged at the center of the slide piece 3 and fitted to the eccentric shaft 21. The second shaft holes 32 correspond one-to-one to the water spraying rods 4 and are fitted to the inner ends corresponding to the water spraying rods 4.
[0019] According to the above means, the present invention installs a slide piece 3 that realizes an interlocking relationship between the impeller 2 and each water spraying rod 4. When the impeller 2 rotates driven by the water flow of the water supply hole 12, the slide piece 3 can be made to perform a circular motion around the axis of the impeller 2, thereby making each second shaft hole 32 on the slide piece 3 perform a circular motion. Further, the water spraying rod 4 is driven by the fitting of the second shaft hole 32 and the inner end of the water spraying rod 4. When the water spraying rod 4 is driven, its middle part is fixed relative to the mounting hole 13, and the inner and outer ends simultaneously perform a circular motion, and finally a rotating water splash is ejected from the water spraying hole 41, and a massage effect can be realized. Due to the action of the simultaneous circular motion of the slide piece 3, all the water spraying rods 4 can realize simultaneous motion, and the angles are unified to be the same, so there is no mutual interference between the rotating water splashes, the spraying area becomes larger, and the massage effect and visual effect are higher.
[0020] The following shows specific embodiments of the present invention.
[0021] The water discharge hole 41 is provided at the axial position of the water discharge rod 4, and a first spherical surface 42 protrudes from the outer peripheral surface of the middle part of the water discharge rod 4. A second spherical surface 14 is recessed in the inner opening of the mounting hole 13 so as to rotate the first spherical surface 42. By fitting the first spherical surface 42 and the second spherical surface 14, the movement direction of the water discharge rod 4 can be guided, and at the same time, the water discharge rod 4 can be prevented from coming out of the mounting hole 13 by the first spherical surface 42.
[0022] A rotating shaft 5 for rotating the impeller 2 is installed at the axial position of the water flow chamber 11.

[0025] Next, the slide piece 3 is fitted to one surface of the partition plate 18 opposite to the impeller 2, and a plurality of protrusions 33 that abut against the surface of the partition plate 18 are provided. By providing the protrusions 33, the slide piece 3 can be brought into contact with the partition plate 18 to reduce shaking, and at the same time, the contact area between the two can be reduced by the protrusions 33 to achieve the purpose of reducing the frictional force. In this embodiment, four protrusions 33 are provided at equal angular intervals around the second shaft hole 32.
[0026] The present invention further includes an elastic sealing member 6, such as a membrane, which is a dynamic seal for sealing the mounting hole 13.

[0027] Furthermore, the elastic deformation portion 61 includes a ring 611 that surrounds the outer peripheral surface of the water discharge rod 4, and a connection ring 612 that is connected between the outer peripheral surface of the ring 611 and the elastic sealing member 6. The connection ring 612 has at least one fold 6121 to achieve conforming deformation.
[0028] In addition, the present invention further includes a pressing plate 7 that is mounted in the water passage chamber 11 and is used to fix the peripheral edge of the elastic sealing member 6.
