The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] In the description of the present utility model, multiple refers to more than two. If there is a description of the first and the second, it is only for the purpose of distinguishing the technical features, and it cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] In the shower system, due to the compact structure of the dial shower, the inner wall water channel is prone to sudden changes in flow rate, which causes obvious structural radiation noise. The excessive water noise affects the user's bathing experience. In the related art, a flow limiting structure is set on the inner wall of the shower to reduce the water inlet speed, thereby reducing the structural radiation noise. However, reducing the water flow rate will cause the speed of water spraying out of the shower to decrease.

[0040] Based on the above problems, according to the water distribution device 1000 of the first embodiment of the utility model, Figure 1 This is a schematic structural diagram of a water distribution device according to an embodiment of the utility model. Figure 2 for Figure 1 A cross-sectional view of Figure 3 for Figure 2 The enlarged schematic diagram of the A area in the middle, refer to Figures 1 to 3 , the water distribution device 1000 of this embodiment includes a shell 100 .

[0041] The housing 100 has a first water diversion chamber 110, and a first water inlet 120 and a first water outlet 130 connected to the first water diversion chamber 110. The first water diversion chamber 110 has a first inner wall 111, and the first inner wall 111 has a buffer groove 112. The first water inlet 120 faces the buffer groove 112 (such as Figure 3 As shown in the figure, the first water inlet 120 is used to supply external water to enter the first water diversion chamber 110, and the first water outlet 130 is used to discharge the water in the first water diversion chamber 110. Specifically, the water diversion device 1000 has a first water diversion chamber 110, and a first water inlet 120 connected to the first water diversion chamber 110, and the first inner wall 111 of the first water diversion chamber 110 opposite to the first water inlet 120 has a buffer groove 112, and the distance between the first water inlet 120 and the first inner wall 111 is increased, thereby reducing the kinetic energy of the water flow entering the first water diversion chamber 110 through the first water inlet 120 when it contacts the first inner wall 111, and further reducing the noise generated when the water flow impacts the first inner wall 111. It can be seen that, compared with the prior art, this embodiment does not need to reduce the flow rate of the water flow entering the first water diversion chamber 110, but only reduces the kinetic energy of the water flow when it contacts the first inner wall 111. Therefore, when the water distribution device 1000 of this embodiment is used for a dial shower, when the water inlet channel of the dial shower is connected to the first water inlet 120, the noise generated when the dial shower is used can be reduced without affecting the flow rate of water spraying out of the shower.

[0042] It should be noted that the water diversion device 1000 of this embodiment has the first water diversion chamber 110, which cannot be interpreted as only the first water diversion chamber 110, and can also have a second water diversion chamber, a third water diversion chamber, etc., which are set according to the switching requirements of the dial shower water path. It is sufficient to ensure that at least one water diversion chamber (generally referring to the first water diversion chamber 110, the second water diversion chamber and the third water diversion chamber) has a buffer groove 112 on its inner wall.

[0043] Reference Figure 3 and Figure 4 , Figure 4 for Figure 1 Another cross-sectional view, in some embodiments, the first water diversion chamber 110 includes an inlet chamber 113 and an outlet chamber 114 that are interconnected, the first water inlet 120 is arranged on the inner wall of the water inlet chamber 113, and the first water outlet 130 is arranged on the inner wall of the water outlet chamber 114, and the cross-section from the water inlet chamber 113 to the water inlet chamber 113 gradually increases, so that the water inlet chamber 113 is an open trumpet shape, and the trumpet-shaped buffer groove 112 can increase the water flow cross-sectional area, reduce the water flow velocity, and reduce the impact of the water flow on the internal structure of the first water diversion chamber 110, thereby reducing the noise generated by the water diversion device 1000 during use.

[0044] Similarly, in some embodiments, the cross-section of the buffer groove 112 gradually increases along the direction from the water inlet chamber 113 to the water outlet chamber 114, which will not be described in detail here.

[0045] Reference Figure 4 On the basis of the above embodiment, the water inlet chamber 113 is connected with the water outlet chamber 114 via the connecting port 115, the water outlet chamber 114 has a second inner wall 1141 arranged opposite to the connecting port 115, and the water diversion device 1000 also has a spoiler 200, one end of the spoiler 200 is arranged at the connecting port 115, and the other end extends obliquely toward the second inner wall 1141, thereby reducing the angle between the water flow flowing from the water outlet chamber 114 to the second inner wall 1141 and the second inner wall 1141, so that the water flow can impact the second inner wall 1141 more smoothly, thereby reducing the noise generated when the water flow impacts. Specifically, the spoiler 200 has a spoiler surface 210 on one side close to the communication port 115, and the spoiler surface 210 is set as an inclined surface or an arc surface deviating from the communication port 115. After the water flow contacts the spoiler surface 210, the flow direction changes, thereby reducing the angle between the water flow from the water outlet cavity 114 to the second inner wall 1141 and the second inner wall 1141. In addition, it can be understood that after the water flow contacts the spoiler 200, it will also partially flow along the first direction, that is, the water flow will form two streams after contacting the spoiler 200, forming a good diversion effect, reducing the global turbulent kinetic energy, thereby reducing the waterway sound source.

[0046] Reference Figure 4 On the basis of the above embodiment, the spoiler surface 210 is set as an arc surface, and the side of the spoiler surface 210 away from the connecting port is tangent to the second inner wall 1141, thereby making the angle between the flow direction of the water after being guided by the spoiler surface 210 and the second inner wall 1141 approach 0 degrees, thereby minimizing the noise generated when the water flow collides with the second inner wall 1141.

[0047] On the basis of the above embodiment, the water outlet chamber 114 also has a water outlet groove 1142 recessed along a first direction, the first direction is the direction from the water inlet 120 to the buffer groove 112, the water outlet groove 1142 has a second side wall 1143 away from the first direction, the spoiler 200 extends into the water outlet groove 1142 along the first direction, and the projection of the connecting port 115 from the water inlet chamber 113 to the water outlet chamber 114 is located on the spoiler 200, thereby, the water flowing to the water outlet chamber 114 through the connecting port 115 can contact the spoiler 200, thereby avoiding the water flow directly impacting the second inner wall 1141, thereby further reducing the noise generated by the water diversion device 1000 of this embodiment during use.

[0048] Reference Figure 3 In some embodiments, the buffer groove 112 has a first side wall 1121 facing the water inlet 120, and the first side wall 1121 extends to the water outlet groove 1142. Therefore, after the water flows into the water inlet cavity 113 through the water inlet 120 and contacts the first side wall 1121, it can flow more smoothly along the first side wall 1121 to the water outlet groove 1142 without being blocked by the side wall of the buffer groove 112, thereby reducing the obstruction to the water flow and reducing the noise generated during the use of the water diversion device 1000 of this embodiment.

[0049] Reference Figure 5 , Figure 5 for Figure 1 , in some embodiments, the shell 100 includes a water inlet 140 and a water outlet 150, the water inlet 140 is connected to the water outlet 150 and defines a first water diversion chamber 110, the water inlet 140 has a first water inlet 120, the water outlet 150 has a first water outlet 130, and the spoiler 200 and the water inlet 140 are formed by integral processing, for example, the spoiler 200 and the water inlet 140 are formed by metal or non-metal injection molding, or metal material stamping, so that the water diversion device 1000 of this embodiment is simpler to process, thereby reducing the manufacturing cost.

[0050] In some embodiments, the depth of the buffer groove 112 ranges from 1mm to 2mm. Specifically, it is understood that, under the premise of a certain thickness of the shell 100, if the buffer groove 112 is too deep, the shell 100 will be too thin at this location, which not only increases the difficulty of processing, but also causes the shell 100 to be insufficiently strong at this location, making the shell 100 easily damaged; if the buffer groove 112 is too shallow, the speed reduction effect of the buffer groove 112 will be reduced. Therefore, this embodiment sets the depth of the buffer groove 112 to a suitable range, that is, the depth of the buffer groove 112 ranges from 1mm to 2mm, which ensures that the shell 100 has a high speed reduction effect under the premise of meeting the use strength.

[0051] Reference Figure 6 and Figure 7 , Figure 6 for Figure 5 Structural diagram of the water inlet section. Figure 7 FIG. 1 is a schematic diagram of an assembly of a dial shower head according to another embodiment of the present invention. The dial shower head according to the second embodiment comprises a housing 300, a dial button 400, and a water distribution device 1000 according to the first embodiment (such as Figure 7 shown).

[0052] The housing 300 has a water inlet channel and a receiving chamber, the water diverter 1000 is installed in the receiving chamber, the dial key 400 is connected to the water diverter 1000, and the dial key 400 can be turned to drive the water diverter 1000 to move relative to the housing 300 to switch the connection between the water inlet channel and the first water inlet 120. Specifically, the water diverter 1000 has a first water diverter chamber 110 and a first water inlet 120 connected to the first water diverter chamber 110, and a first inner wall 111 of the first water diverter chamber 110 opposite to the first water diverter has a buffer groove 112, so as to increase the distance between the first water inlet 120 and the first inner wall 111, thereby reducing the kinetic energy of water entering the first water diverter chamber 110 through the first water inlet when contacting the first inner wall 111, and further reducing the noise generated when the water flow impacts the first inner wall 111. It can be seen that, compared with the prior art, this embodiment does not need to reduce the flow rate of water entering the first water diversion chamber 110, but only reduces the kinetic energy of the water when it contacts the first inner wall 111. Therefore, when the water inlet channel is connected to the first water inlet 120, it can reduce the noise generated when the dial shower is used without affecting the flow rate of water spraying out of the shower.

[0053] In addition, the water distribution device 1000 of this embodiment has a first water distribution chamber 110, which cannot be interpreted as only the first water distribution chamber 110, and can also have a second water distribution chamber, a third water distribution chamber, etc. The housing 100 of the water distribution device 1000 has a water inlet 140 and a water outlet 150, and the water inlet 140 has a first water distribution tank 141, a second water distribution tank 142 and a third water distribution tank 143 (such as Figure 6 As shown in the figure, when the water inlet 140 is connected to the water outlet 150, the first water diversion groove 141, the second water diversion groove 142 and the third water diversion groove 143 respectively define the first water diversion chamber 110, the second water diversion chamber and the third water diversion chamber. According to the user's usage requirements, the dial key 400 is swung to selectively connect the water inlet channel with the first water diversion chamber 110, the second water diversion chamber and the third water diversion chamber, thereby realizing water path switching.

[0054] It should be noted that, since the dial shower head adopts all the technical solutions of the water distribution device 1000 of the first embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0055] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
