The fifth technical scheme, be equipped with first water hole of crossing through water portion, first water hole and crossing water chamber and delivery port intercommunication, thereby realize crossing the water, prevent that direct when locating the external tooth with first water hole of crossing, external tooth intensity reduces, the problem of easy damage, and if locate the external tooth with first water hole of crossing, because the number of teeth of external tooth need keep normally incessant messenger external tooth and internal tooth meshing smooth and easy, then the external tooth edge can not be located in first water hole of crossing, can only set up in the position that is close to the middle part, so the position of apopore need with this first position direct correspondence of crossing the water hole, the position setting of apopore is not nimble enough.

6. The sixth technical scheme locates the external tooth through the tooth spare cover and offsets so that cross water portion and laminate in the plane at delivery port place and prevent that internal tooth and external tooth break away from the meshing to guarantee that operating condition is smooth, prevent that the motion process from rocking and make internal tooth and external tooth break away from the meshing and lead to damaging, make cross water portion not laminate in the plane at delivery port place and lead to going out water status not to switch, need the user to dismantle the maintenance, increase cost and probably reduce life's problem.

7. The seventh technical scheme is that a first water outlet and a second water outlet which are respectively communicated with the first cavity and the second cavity are formed in the body, and the proportion of water entering the first cavity and the second cavity is adjusted through the switching piece. Because the second water hole intercommunication first chamber and second chamber for the water in the second intracavity can get into first chamber through the second water hole. The water outlet direction of the second water passing hole faces to the hole wall of the corresponding water outlet hole, so that the water outlet of the second water passing hole can impact the hole wall of the water outlet hole to be scattered to form granular water. Because first chamber and apopore intercommunication, the water in first chamber and second chamber can flow out from the apopore simultaneously.

8. The eighth technical scheme sets up the apopore and reduces along its water direction aperture gradually for the apopore pore wall is the conical surface, and the effect of the water of breaing up is better.

9. The ninth technical scheme is that the first convex column and the second convex column are arranged to increase the length of the water outlet hole and increase the number of times of scattering water flow.

10. The tenth technical scheme, through the slope of a plurality of second water holes sets up and the axis ring equipartition of duplex winding apopore rather than corresponding for the aquatic of entering this apopore produces the whirl, increases bathing experience.

In use, referring to fig. 10, the water inlet 1231 feeds water, the water enters the first water collecting cavity 191 and then enters the second water collecting cavity 192 through the water through hole 1241, and drives the impeller to rotate around the first axis relative to the body 1, and because the output end of the impeller is parallel to the first axis and the switching member 3 is rotatably connected with the output end of the impeller, the impeller can drive the switching member 3 to move around the first axis relative to the body 1 when rotating around the first axis due to the eccentric arrangement of the output end. Since outer teeth 31 of switching member 3 are engaged with inner teeth 1251 of main body 1 and switching member 3 is rotatably connected to the output end of the impeller, switching member 3 can rotate relative to the impeller. When the impeller rotates around the first axis to drive the switching part 3 to move around the first axis relative to the body 1, the engagement state of the outer teeth 31 and the inner teeth 1251 does not cause the switching part 3 to be locked, but the switching part 3 rotates relative to the impeller by taking the second axis as a rotating axis, teeth on the outer teeth 31 are disengaged from the inner teeth 1251, after the switching part 3 rotates one tooth, new teeth are engaged with the inner teeth 1251 again, in the engagement process, because the second tooth number is smaller than the first tooth number, when the impeller drives the switching part 3 to rotate, each tooth of the switching part 3 needs to be engaged with each tooth of the inner teeth once, the time of one circle rotation of the switching part 2 is longer than that of one circle rotation of the impeller, the ratio of the rotating speed of the switching part 3 to the rotating speed of the impeller is 1/first tooth number, namely, the speed reduction multiplying factor is 1/first tooth number, and the speed reduction function is realized.

When the impeller rotates around the first axis to drive the switching piece 3 to move around the first axis relative to the body 1, the position of the first water through hole 321 changes due to the change of the position of the switching piece 3 relative to the body 1, when the switching piece 3 rotates due to meshing, the position of the first water through hole 321 changes due to rotation relative to the body 1, and the communication state of the first water through hole 321 with the first water outlet 1211 and the second water outlet 1212 changes due to the change of the position of the first water through hole 321 caused by the two factors, so that the water outlet states of the first water outlet 1211 and the second water outlet 1212 are switched, and the water outlet 1711 is influenced finally; therefore, the switching piece 3 moves around the first axis relative to the body 1 and the switching piece 3 rotates around the second axis to realize the switching of the water outlet state, wherein the rotation of the switching piece 3 is dominant in the process of switching the water outlet state.

The change of the water outlet state can refer to the change of opening and closing or the change of the water outlet quantity, namely the opening and closing change caused by opening or completely shielding the water outlet by the switching piece 3, and the change of the water outlet quantity caused by always opening the water outlet and changing the shielding area so as to change the area of the water outlet.

Referring to fig. 11, when the water in the second water collecting chamber 192 completely exits from the first water outlet 1211 or the water output of the second water outlet 1212 is too small compared to the water output of the first water outlet 1211, the water finally exiting from the water outlet 1711 is visually straight, as shown in fig. 12, when the water output from the second water outlet 1212 increases, the water exiting from the second water passing hole 1811 hits the hole wall of the water outlet 1711 due to the water exiting direction of the second water passing hole 1811 facing the hole wall of the corresponding water outlet 1711, the particles are smaller, and the three second water passing holes 1811 are obliquely arranged and circumferentially distributed around the axis of the water outlet 1711 corresponding to the three second water passing holes 1811, and the water finally exiting from the water outlet 1711 is visually swirling, as shown in fig. 13, when the water output from the second water outlet 1212 is the maximum, as shown in fig. 14; due to the effect of speed reduction, the change speed in the process is not fast, people can feel the change from vision and experience, the automatic change process from straight water to particle water is realized in a mode of driving the impeller by water power, the automatic change is carried out by taking the images 12-14 as a change period, the change process is stepless change, the particle size is stepless automatic change, the individualized requirements of consumers on different particle sizes of the splash can be well met, the shower comfort and experience are improved, the structure is convenient to produce and process, the cost is low, and the practicability is very strong.

In the preferred embodiment, the first number of teeth is N, the second number of teeth is (N-1), and each tooth of the external teeth 31 needs to be meshed with each tooth of the internal teeth 1251 once, so that when the impeller rotates N times, the external teeth 31 rotates 1 time, the speed reduction ratio is 1\ N, the speed can be reduced by N times, and unsmooth meshing when the difference in the number of teeth is too large is prevented. In this embodiment the first number of teeth is 12-14 and the second number of teeth is correspondingly 11-13, preventing too low a number of teeth leading to insufficient strength.

It should be understood that the rotating member 2 may also be a motor, the motor is provided with a transmission shaft and an output shaft which rotate around the first axis, wherein one end of the transmission shaft extends along a direction parallel to the first axis, the output shaft forms an output end of the motor, the output shaft is parallel to the first axis and is fixedly connected with the transmission shaft, the output shaft of the motor rotates to drive the switching member 3 to move, and the motor can be completely arranged in the water passing cavity or only the output shaft thereof is arranged in the water passing cavity. The water outlets of the water passing chamber in this embodiment include the first water outlet 1211 and the second water outlet 1212, but only one or more water outlets may be provided, and the first water outlet 1211 and the second water outlet 1212 may be sized such that the first water passing hole 321 communicates with only one of them or allows both of them to communicate with each other.
