Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The utility model will now be further described with reference to the accompanying drawings and detailed description.

The present embodiment provides a cup-less multi-state water outlet assembly, as shown in fig. 1-5, which is described by taking the most common hand-held shower as an example, but not limited thereto, and can be applied to other water outlet assemblies such as a top shower, a faucet, etc.

The shower head comprises a shower head body 1, a face cover 2 and a water distribution component 3. The shower body 1 is provided with a water inlet end 11 and a water outlet end 12, the water outlet end 12 of the shower body 1 is provided with a concave cavity 13, and the water inlet end 11 is communicated with the concave cavity 13 through a water channel 14.

The face is covered 2 and is installed in the opening side of cavity 13 to face is covered 2 and is covered the opening side seal of cavity 13 and cover, and the face is covered and is had the multiunit apopore, and every group apopore corresponds a play water state. The present embodiment is described by taking an example that the face cover 2 has three sets of outlet holes with different outlet states, but the present invention is not limited thereto, and the number of the outlet states may be increased or decreased, for example, two outlet states, four outlet states or more. The face cover 2 in this embodiment has a first group of outlet holes 21 located at the center, a second group of outlet holes 22 located on the outer periphery of the first group of outlet holes 21, and a third group of outlet holes 23 located on the outer periphery of the second group of outlet holes 22.

The water diversion component 3 is positioned in the concave cavity 13 and comprises a water inlet disc 31 and a water diversion disc 32, the water inlet disc 31 and the shower body are sealed and enclosed to cover the outlet of the water channel 14 in the shower body 1, and the water inlet disc 31 is provided with a plurality of water passing holes 310. The water diversion disc 32 is provided with water passing channels which are matched with the water outlet holes on the surface cover 2, and the surface cover 2 in the embodiment is provided with three groups of water outlet holes, so that the water diversion disc 32 is also provided with a first water passing channel group 321 corresponding to the first group of water outlet holes 21, a second water passing channel group 322 corresponding to the second group of water outlet holes 22 and a third water passing channel group 323 corresponding to the third group of water outlet holes 23. The water diversion disc 32 can rotate relative to the water inlet disc 31 to allow the water inlets of the water passing channels of different groups to be arranged opposite to the water passing holes 310 on the water inlet disc 31, so that water flows into the corresponding water passing channels, and finally flows out from the water outlet holes 22 corresponding to the face covers to realize the adjustment of different water outlet states.

The above-mentioned water diversion structure is only an example which is most common in the prior art, and the water diversion structure can be replaced by other water diversion structures which can realize the same water diversion function in the prior art.

Because the multistation play water subassembly that this embodiment provided need not to realize the subassembly that divides water sealed when dividing water with the help of the leather cup, consequently need control the ratio of pressure release water gap area and water inlet area and be greater than 1.5, preferred ratio is greater than 1.8, more excellent ratio is greater than 2.0, so that let the water that flows in from the water inlet can follow the quick outflow in pressure release water gap, in order to reduce the backpressure influence, thereby realize not having the leather cup also can not appear leaking, and then solved among the prior art by the sealed problem that leads to of leather cup.

In this embodiment, on the premise that the water pressure in the pipeline is constant, the inlet flow is limited by the sum of the cross-sectional areas of all the water holes 310 on the water inlet tray 31, and the outlet flow is limited by the smaller of the sum of the minimum cross-sectional areas of the water passing channels on the water distribution tray and the sum of the cross-sectional areas of the water outlet holes on the surface cover. In general, the sum of the cross-sectional areas of the outlet openings of the face cover is relatively small, so that the outlet flow is limited to the sum of the cross-sectional areas of the outlet openings of the respective groups. Therefore, in this embodiment, the sum of the cross-sectional areas of all the water passing holes on the water inlet tray is the water inlet area, and the sum of the cross-sectional areas of the groups (first, second, or third) of the water outlet holes on the surface cover is the pressure relief water inlet area, that is, the ratio of the sum of the cross-sectional areas of all the water passing holes on the water inlet tray to the sum of the cross-sectional areas of the first group of the water outlet holes is greater than 1.5, the ratio of the sum of the cross-sectional areas of all the water passing holes on the water inlet tray to the sum of the cross-sectional areas of the second group of the water outlet holes is greater than 1.5, and the ratio of the sum of the cross-sectional areas of all the water passing holes on the water inlet tray to the sum of the cross-sectional areas of the third group of the water outlet holes is greater than 1.5. In the prior art, the sum of the cross-sectional areas of the first group of water outlet holes at the center of the face cover is smaller than the sum of the cross-sectional areas of the second group of water outlet holes and the third group of water outlet holes, so that the problem of water leakage can be avoided under other water outlet states under the condition that the ratio of the sum of the cross-sectional areas of all the water passing holes on the water inlet disc to the sum of the cross-sectional areas of the first group of water outlet holes is more than 1.5.

In this embodiment, referring to fig. 1, 6-9, the water diversion assembly 3 further includes a rectifying plate 33 and a flow guiding plate 34, the rectifying plate 33 and the flow guiding plate 34 are sequentially disposed between the water diversion disk 32 and the face cover 2 along the water outlet direction, and the rectifying plate 33 and the flow guiding plate 34 cooperate with each other to form a grid for distributing the water channel to each water outlet hole, so as to reduce the influence of back pressure.

Preferably, the flow guiding plate 34 is further provided with a flow guiding wall 341 matched with each group of water outlet holes, so that the water outlet can be guided into each water outlet hole according to the wall attachment effect of the fluid, and the influence of back pressure is reduced to the greatest extent.

More preferably, the end of the flow guiding wall 341 is further provided with a flow guiding column 342, and each flow guiding column 342 is disposed corresponding to one water outlet, so that the water can be guided into each water outlet, and the influence of back pressure can be reduced to the greatest extent.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
