[0045] Reference Figures 2-7In some specific embodiments of the utility model, the spray head 1000 includes a shell 100 and a turbine 200, the shell 100 is provided with first water inlet channel 111, first water passing cavity 130 and water outlet hole 113 that communicate sequentially, still includes second water inlet channel 112.Turbine 200 is composed of blade 210 and rotating shaft 220, turbine 200 is arranged in first water passing cavity 130, water flow can enter first water passing cavity 130 from first water inlet channel 111 and impact the blade 210 of turbine 200, make turbine 200 rotate, turbine 200 is rotated in the process and stirs water flow rotation and carries out pressurization to water flow, makes water flow be in whirlpool state in whole first water passing cavity 130, water flow is thrown out from first water outlet hole 113 under the action of water pressure and rotation force and forms the water outlet effect of granular water, compared with ordinary water column water outlet, granular water is more soft, impact force is not obvious, and the flushing experience is better.

[0046] Among them, the rotating shaft 220 of turbine 200 is hollow structure, the hollow structure of turbine 200 is second water passing cavity 221 that can be used for water flow, second water inlet channel 112, second water passing cavity 221 and water outlet hole 113 communicate sequentially, to make water flow can enter second water passing cavity 221 from second water inlet channel 112, then flow from water outlet hole 113.Therefore, the water flow entering from second water inlet channel 112 does not flow through first water passing cavity 130, but is directly sprayed out through the rotating shaft 220 of turbine 200 without any special treatment, at this time, the output water flow is ordinary water column.

[0047] According to the spray head 1000 provided by the utility model embodiment, two different water outlet modes can be provided for user selection, the spray head 1000 sets the second water passing cavity 221 by the rotating shaft 220 of turbine 200, and is installed in the first water passing cavity 130, and the two water passing cavities share one water outlet hole 113, so that two water types are provided by a single hole, and user only needs to select target water inlet channel, without separately setting water outlet hole or water passing cavity, and the second water passing cavity 221 also does not occupy the volume of other positions of the spray head 1000, therefore, the structure design of the spray head 1000 is more simple and compact, and the miniaturization of the spray head 1000 is facilitated.

[0048] Referring to FIG. 5, FIG. 9 and Figure 13 In some specific embodiments of the utility model, the end face of rotating shaft 220 close to water outlet hole 113 and the inner wall surface of first water passing cavity 130 exist gap between.And, the outer peripheral wall of rotating shaft 220 of turbine 200 is provided with separation disc 230, specifically, separation disc 230 is arranged on one end of rotating shaft 220 close to second water inlet channel 112, along the plane direction perpendicular to rotating shaft 220, the cross-sectional shape of separation disc 230 is substantially same with the shape of first water passing cavity 130, therefore, separation disc 230 can be arranged in first water passing cavity 130 together with turbine 200.

[0049] When there is no water flow from the second water inlet channel 112, the turbine 200 and the partition disc 230 stop on the bottom wall of the first water passing cavity 130 under the action of gravity, and at this time, the first end 2211 of the second water passing cavity 221 is sealed by the bottom wall of the first water passing cavity 130 (as shown in FIG. 7); when the water flow enters the first water passing cavity 130 from the first water inlet channel 111, the gravity of the water flow will exert pressure on the partition disc 230, and the turbine 200 and the partition disc 230 do not move in the axial direction of the turbine 200 (as shown in FIG. 7), and the water flow in the first water passing cavity 130 can enter the water outlet hole 113 from the gap between the rotating shaft 220 and the inner wall surface of the first water passing cavity 130 and be sprayed out, and since the first end 2211 of the second water passing cavity 221 is sealed, even if part of the water flow enters the second water passing cavity 221, it will not overflow into the second water inlet channel 112; when the water flow flows from the second water inlet channel 112, the partition disc 230 is pushed by the water pressure, and since the gap between the rotating shaft 220 and the inner wall surface of the first water passing cavity 130 provides a moving stroke space for the turbine 200, the partition disc 230 moves away from the bottom wall of the first water passing cavity 130, that is, the turbine 200 moves in the water outlet direction (as shown in FIG. 8), and at this time, the first water passing cavity 130 is divided into a first cavity 131 and a second cavity 132 by the partition disc 230, and after the water flow in the second water inlet channel 112 enters the second cavity 132, it enters the second water passing cavity 221 through the first end 2211, and the end surface of the end of the rotating shaft 220 close to the water outlet hole 113 is in close contact with the inner wall surface of the first water passing cavity 130, eliminating the gap, so that after the water flow passing through the second water passing cavity 221 exits the second end 2212, it directly enters the water outlet hole 113 and is sprayed out, and will not leak to the first cavity 131 during the spraying process, causing the water flow to overflow into the first water inlet channel 111.

[0050] According to the embodiments provided by the utility model, the nozzle 1000 completes the control of the water flow in the water outlet process of the two water types through the cooperation of the end surface of the rotating shaft 220 of the turbine 200 and the partition disc 230, thereby avoiding the problem of water flow overflow into the water inlet channel of the other water type when any one of the water types is outflowing.

[0051] Reference Figure 6 , Figure 9 and Figure 12 In some specific embodiments of the utility model, a first groove 121 is arranged on the bottom wall of the first water passing cavity 130, and the first groove 121 is in communication with the second water inlet channel 112 and the first water passing cavity 130; when the partition disc 230 stops on the bottom wall of the first water passing cavity 130, the end of the partition disc 230 close to the first groove 121 and the first groove 121 form an inlet channel for the water flow; when the water flow enters from the second water inlet channel 112, it can enter and contact the side of the partition disc 230 close to the bottom wall of the first water passing cavity 130 through the first groove 121, so that the water flow can push the partition disc 230 to move.

[0052] Reference Figure 5 、 Figure 9 and Figure 13 In some embodiments of the present application, the second water passage 221 includes a first end 2211 close to the bottom wall of the first water passage 130 and a second end 2212 close to the water outlet hole 113, wherein the first end 2211 is in communication with the second water inlet channel 112 for water flow to flow into the second water passage 221, and the second end 2212 is in communication with the water outlet hole 113 so that the water flow in the second water passage 221 can be sprayed out through the water outlet hole 113. The bottom wall of the first water passage 130 is provided with a first boss 123, the position of the first boss 123 corresponds to the first end 2211 of the second water passage 221, and the shape of the first boss 123 is adapted to the first end 2211. Thus, when the partition disc 230 is stopped on the bottom wall of the first water passage 130, the first boss 123 can penetrate into the first end 2211, thereby completing the plugging of the second water passage 221, and avoiding the water flow from the first water inlet channel 111 into the first water passage 130 through the second water passage 221 into the second water inlet channel 112 causing back overflow. At the same time, the penetration of the first boss 123 into the first end 2211 can also realize the positioning of the rotating shaft 220, preventing the turbine 200 from shifting when rotating.

[0053] Referring to FIGS. 2, 3, Figure 11 and Figure 12 In some embodiments of the present application, the shell 100 is composed of an upper shell 110 and a lower shell 120. Specifically, the first water inlet channel 111, the second water inlet channel 112 and the water outlet hole 113 are all arranged in the upper shell 110, and the upper shell 110 is further provided with a first recess hole 114 in communication with the water outlet hole 113. The lower shell 120 is provided with a second recess hole 124. When the upper shell 110 and the lower shell 120 are spliced into the shell 100, the first recess hole 114 and the second recess hole 124 are spliced into the first water passage 130.

[0054] According to the embodiments provided by the present application, the split splicing design of the upper shell 110 and the lower shell 120 can reduce the production difficulty of the spray head 1000, and when the inside of the spray head 1000 is blocked or dirty and needs to be cleaned, the user can conveniently disassemble the shell 100 for cleaning.

[0055] Reference Figures 9-12In some specific embodiments of the utility model, first recess 121 is arranged on the bottom wall of second recess hole 124, and second recess 122 is further arranged on the side wall of second recess hole 124, specifically, second recess 122 can be a recess formed by the outward recess of the side wall of second recess hole 124, one end of second recess 122 is connected with first recess 121, and the other end is connected with second water inlet channel 112. The side wall of first recess hole 114 extends out annular plate 115 along the direction close to second recess hole 124, when upper shell 110 and lower shell 120 are spliced, annular plate 115 penetrates into second recess hole 124, at this time, annular plate 115 separates second recess hole 124 and second recess 122, and forms an independent channel for water flow in cooperation with second recess 122, one end of the channel is communicated with second water inlet channel 112, and the other end is communicated with first recess 121, the water flow flowing into second water inlet channel 112 can enter first recess 121 and push the partition plate to move.

[0056] It can be understood that first recess 121 and second recess 122 can be provided with multiple, and the number of first recess 121 and second recess 122 is same.

[0057] According to the embodiments provided by the utility model, second recess 122 is separated from second recess hole 124 by annular plate 115, so that water flow can directly pass to first recess 121 to push the partition plate to move, avoiding water flow from flowing in first water passing cavity 130 and affecting water outlet effect. On the other hand, annular plate 115 can also realize positioning effect, so that upper shell 110 and lower shell 120 are positioned, avoiding relative sliding between the two and causing separation.

[0058] Reference Figures 9-11 In some specific embodiments of the utility model, annular plate 115 is provided with notch 1151, further, the opening direction of notch 1151 is towards the bottom wall of first water passing cavity 130, first water inlet channel 111 and first water passing cavity 130 are communicated through notch 1151, that is, the water flow in first water inlet channel 111 can flow into first water passing cavity 130 through notch 1151.

[0059] Reference Figure 9 、 10, 12, 13, in some specific embodiments of the utility model, the bottom wall of second recess hole 124 is provided with second boss 125, and second boss 125 is provided with gap 1151, specifically, second boss 125 is connected with the bottom wall and the side wall of second recess hole 124, when upper shell 110 and lower shell 120 are spliced, second boss 125 can be embedded in the opening of gap 1151, and gap 1151 is enclosed to form the connecting port of first water inlet channel 111 and first water passing cavity 130, it can be understood that, at this time, second boss 125 is located on the water inlet path of first water inlet channel 111, after water flow flows into first water inlet channel 111, impinges on second boss 125 and then flows into first water passing cavity 130.

[0060] According to the embodiments provided by the utility model, second boss 125 is equivalent to being clamped with annular plate 115, which limits the rotation of annular plate 115 in second recess hole 124, thereby avoiding the relative rotation between upper shell 110 and lower shell 120. On the other hand, since the separation disc 230 itself has a certain thickness, after the annular plate 115 penetrates into the second recess hole 124, a groove is formed between the outer circumferential surface of the separation disc 230, the bottom wall of the second recess hole 124, the side wall and the side wall of the gap 1151, and the height of the groove is less than the height of the first water passing cavity 130 (the height of the end surface of the separation disc 230 close to the first water passing cavity 130), therefore, after the water flow enters through the first water inlet channel 111, it will first enter the groove and then turn back into the first water passing cavity 130, at this time, the impact direction of the water flow changes, which cannot be perpendicular to the rotating shaft 220, and cannot better push the turbine 200 to rotate, at the same time, it will also cause turbulence, leading to the kinetic energy loss of water flow, reducing the efficiency of converting the kinetic energy of water flow into the kinetic energy of turbine 200.

[0061] In some specific embodiments of the utility model, the height of second boss 125 can be variable, for example, the height of second boss 125 gradually decreases from the side close to the side wall of second recess hole 124 to the side close to rotating shaft 220, at this time, the top surface of second boss 125 forms a flow guide surface, and the water flow can be better guided into first water passing cavity 130 to impact turbine 200.

[0062] Reference Figure 9 And Figure 13 In some specific embodiments of the utility model, the gap distance between the end surface of rotating shaft 220 close to water outlet hole 113 and the inner wall surface of first water passing cavity 130 is defined as S1, the height of first boss 123 is S2, and the height of second boss 125 is S3, wherein S3>S1>S2.

[0063] Thus, when the water flow pushes the partition disc 230 to move and makes the rotating shaft 220 close to the inner wall surface of the first water passing cavity 130, the moving distance of the rotating shaft 220 in the water outlet direction is S1, since S1>S2, at this time, the first boss 123 can be completely separated from the second water passing cavity 221, and the first end 2211 is completely exposed, therefore, the water flow can smoothly pass through the second water passing cavity 221 to outlet, and since the height S3 of the second boss 125 is greater than S1, even if the rotating shaft 220 completely adheres to the inner wall surface of the first water passing cavity 130, at this time, the height of the surface of the partition disc 230 close to the second groove 122 is still less than the height of the second boss 125, therefore, the gap 1151 is not exposed in the second cavity 132, and therefore, the water flow in the second cavity 132 can only pass through the second water passing cavity 221 to outlet, and cannot return to overflow into the first water inlet passage 111.

[0064] According to the embodiments provided in the present application, by setting the relative size among S1, S2 and S3, the control of the water outlet direction of the second water passing cavity 221 can be realized, and the water flow can be controlled to enter the second water passing cavity 221 and cannot return to overflow into the first water inlet passage 111.
