With the above structure, the water passage 200 communicates the water outlet cavity 10 and the water outlet gap 100, and one end of the water outlet groove 210 away from the abutting surface 2131 is open. It should be understood that the water passage 200 may also be formed on the annular wall 122 independently, and need not be formed by the abutting surface 2131 and the water passage 1221, that is, the water passage 200 may be formed by the body 1 or the rotating member 2 of the body 1, and this embodiment is provided as an example.

The rotating portion 22 and the protruding portion 21 are integrally formed, and include a plurality of blades 221, each blade 221 is arranged at intervals along the circumferential direction and is fixedly connected to an end of the protruding portion 21 away from the abutting surface 2131, so as to form an impeller structure, the impeller structure is coaxial with the protruding portion 21, is located in the water outlet cavity 10, and has a top end abutting against an inner surface of the sealing cover 13, that is, in the present embodiment, the inner surface of the sealing cover 13 restricts the rotating member 2 from displacing in the axial direction by cooperating with an end surface of the annular wall 122; the inclined water passage 1211 is directed to the rotating portion 22 and is capable of guiding water flow to push the rotating portion 22 to rotate so as to achieve the rotating function of the rotating member 2, it should be understood that the rotation of the rotating member 2 relative to the body 1 can also be achieved by electric driving, and this embodiment is only an example, and the rotation is driven by hydraulic power, and the energy consumption is low, the structure is simple, and the rotating function is reliable.

In this embodiment, a water outlet channel 23 which is through in the axial direction is coaxially arranged in the protruding portion 21, the water outlet channel 23 is communicated with the water outlet cavity 10 and has at least one water outlet 231, specifically, the water outlet 231 may be in a spindle shape as shown in fig. 10, or may be a plurality of column holes which are at different distances from the axis of the protruding portion 21 as shown in fig. 11, or a plurality of fan blade holes which are circumferentially arranged, or a plurality of linear holes which extend in the radial direction, wherein the spindle-shaped water outlet holes can form blade-shaped water outlet; each column hole can be positioned in the same radial direction or distributed in different radial directions, and can form water curtain-shaped water outlet; the fan blade holes or the linear holes can form a water curtain-shaped water outlet with a certain thickness, and it is worth explaining that, because the rotating part 2 rotates when water is discharged, referring to the effect comparison graphs of fig. 12 and 13 and fig. 14 and 15, the water outlet distribution amount of the water outlet channel 23 is increased by geometric multiples compared with the water outlet distribution amount without rotation, the water outlet is fine and smooth, the massage effect is good, and the use experience of a user is good.

It can be seen from the above structure that in the water outlet device, the water flowing from the water inlet channel 111 can flow into the inclined water channel 1211 and the water outlet cavity 10 through the water passing gap and the gap between the side wall of the seat body 121 and the inner wall of the housing 11, and then flows into the water outlet gap 100 through the water passing channel 200, the water outlet gap 100 can form an annular water curtain-shaped water outlet, and the rotating member 2 can rotate under the driving of the water flow, so the water outlet gap 100 forms a rotating water curtain-shaped water outlet, which has a good massage effect.

As shown in fig. 3, the apopore is a circular cone hole, its big end port is located play water cavity 10 one side, the tip port is used for going out water, make the interval of play water clearance 100 reduce along the play water direction from this, this structure makes the rivers have great play water initial velocity along the play water direction in the play water clearance 100, the pressure boost effect is obvious, consequently under the unchangeable circumstances of 2 centrifugal forces of rotation piece, be favorable to reducing the relative play water direction's of rotatory play water curtain opening angle and weaken the trend that rotatory play water curtain flies to get rid of toward the periphery, thereby make the rivers of rotatory play water curtain more concentrate and full, it is also better to user's washing effect and massage effect. It should be understood that the reduction of the water gap 100 can also be achieved by providing the side walls of the rotor 2 with conical surfaces, and this embodiment is given as an example only.

Preferably, as shown in fig. 4, in the present embodiment, the width of the water outlet groove 210 is also reduced along the water outlet direction, first, the water outlet groove 210 is configured such that the water outlet gap 100 at the water outlet groove 210 can form a water curtain portion with a relatively large thickness, the relatively thick water curtain portion can provide a relatively large flushing force to a person, and during the rotation of the rotating member 2, the relatively thick water curtain portion can change in position along with the position change of the water outlet groove 210, so as to provide a pulse type massage experience to the user sensorially. In addition, because the width of the water outlet groove 210 is reduced along the water outlet direction, the corresponding water outlet flow at the water outlet groove 210 also has a larger initial water outlet speed and a larger pressurization effect, so that the splashing prevention capability of the rotary water outlet curtain is further enhanced, and the aims of further improving the plumpness, the flushing effect and the massage effect of the rotary water outlet curtain are fulfilled.

In addition, because the play water clearance 100 and play water cavity 10 pass through water channel 200 intercommunication, the water passing area of water channel 200 is little, when rivers get into water channel 200 by a play water cavity 10, the reduction of water passing area, make the velocity of water inevitably accelerate, and then make the rivers that get into in the play water clearance 100 have great velocity of flow, and further strengthened the play initial velocity of rivers along the play water direction in the play water clearance 100, be favorable to further offsetting the influence of centrifugal force to the play water curtain, strengthen the ability of preventing splashing of rotatory play water curtain, washing effect and massage effect.

As shown in fig. 5 and 6, the water outlet direction of the water channel 200 is inclined with respect to the axial line and radial direction of the rotating member 2, and the tangential component of the inclined direction is opposite to the rotating direction of the rotating member 2, and the water flow guided by the water channel 200 can apply a thrust opposite to the rotating direction of the rotating member 2 when impacting the rotating member 2 (especially impacting the groove wall of the water outlet groove 210), so that the rotating speed of the rotating member 2 is reduced, thereby reducing the centrifugal force applied to the rotating water curtain, further helping to reduce the opening angle of the water curtain with respect to the water outlet direction and weakening the tendency of the water curtain flying and throwing towards the periphery, so as to improve the plumpness, flushing effect and massage effect of the rotating water curtain.

More preferably, as shown in fig. 4, in this embodiment, the outlet channel 210 is provided with an inclined channel section extending to the bottom opening, and the inclined direction of the inclined channel section is opposite to the rotation direction of the rotating member 2, so that the outlet direction of the outlet channel 210 is inclined relative to the axial direction of the rotating member 2 and the inclined direction is opposite to the direction of the rotating member 2, that is, the outlet direction of the outlet channel 210 is opposite to the direction of the centrifugal force applied to the rotating outlet waterway, which reduces the influence caused by the centrifugal force in the tangential direction, and weakens the inertia of the rotating outlet water curtain thrown out along the rotation direction under the action of the centrifugal force, thereby further reducing the opening angle of the rotating outlet water curtain relative to the outlet direction and weakening the phenomenon of the outlet water curtain thrown out to the periphery.

More preferably, as shown in fig. 7 and 8, the water through holes 134 on the seal cover 13 are directed to the rotating portion 22 in a direction parallel to the rotation axis direction, which guides the water flow to impact the rotating portion 22 and applies rotational resistance to the rotating portion 22 to reduce the rotation speed of the rotating member 2, further reducing the influence of centrifugal force on the rotation of the discharged water curtain.

It can be seen that the present embodiment mainly achieves the effects of reducing the opening angle of the rotating water outlet curtain relative to the water outlet direction and preventing the water outlet curtain from splashing to the periphery through the above six modes, wherein, the first three modes are mainly to gradually enhance the initial outlet speed of the water flow in the outlet gap 100 in three aspects to achieve the purpose of offsetting the influence of the centrifugal force on the rotating outlet water curtain, the last three modes are to directly weaken the influence of the centrifugal force from the tangential direction, the rotary water outlet curtain can also achieve the purpose of reducing the opening angle of the rotary water outlet curtain, the opening angle of the rotary water outlet curtain relative to the water outlet direction can be controlled by combining six aspects, and a good anti-splashing effect is achieved, the rotary water outlet curtain in the embodiment surrounds the periphery of the water outlet spray flowing out of the water outlet channel 23, therefore, the water outlet channel 23 can shield the water outlet spray from splashing, so that the whole water outlet has a better splashing prevention effect.

It should be noted that, in practical application, good splash-proof effect can be obtained to a certain extent by using the first three ways, and therefore, in order to meet the use requirements of some special scenes which have requirements on the granularity of the outlet water splash, as shown in fig. 16, by setting the outlet direction of the water passage 200 to be inclined relative to the axial direction and the radial direction of the rotating member 2, and setting the tangential component of the inclined direction to be the same as the rotating direction of the rotating member 2, it is beneficial to enhance the outlet water flow speed of the rotating outlet water flow along the rotation to an objectively allowable degree, so as to provide the outlet water splash with fine granularity for these use scenes.

When the water outlet apparatus provided in this embodiment is assembled, first, the portion of the protruding portion 21 of the impeller, which has the protruding block 212, extends into the water outlet hole from the inner cavity side of the seat body 121, the second sealing ring 4 is placed on the step surface 1212 of the seat body 121, the sealing cover 13 is covered on the open end of the seat body 121 with the protruding rib 133 facing outward, the clamping grooves 132 on the sealing cover are aligned and clamped with the clamping buckles 1213 on the seat body 121, the first sealing ring 3 is sleeved in the annular limiting groove 1214 on the outer wall of the seat body 121, then the base 12 is screwed into the mounting cavity 112 of the housing 11 in a state that the sealing cover 13 faces the inner step hole shoulder 110 of the housing 11, and when the protruding rib 133 on the sealing cover 13 abuts against the hole shoulder 110 of the inner step hole of the housing 11, the installation is completed.
