In addition to intermittently shielding the first water outlet holes 430 by means of the first shielding portions 710, referring to fig. 13 and 14, in another embodiment of the present invention, the outgoing water tray 400 includes a plurality of track grooves 440 recessed toward the opposite side from the second tooth portions 420, the plurality of track grooves 440 are uniformly arranged along the circumferential direction of the outgoing water tray 400, the plurality of first water outlet holes 430 includes a plurality of fifth hole portions 433 and a plurality of sixth hole portions 434, for example, a part of the plurality of first water outlet holes 430 is the fifth hole portions 433, and another part of the plurality of first water outlet holes 430 is the sixth hole portions 434. The fifth holes 433 are provided in the end wall of the outlet tray 400, and the sixth holes 434 are provided in the bottom wall of the track groove 440. The shutter assembly 700 includes a plurality of shutter pieces 720 and a plurality of elastic members 730, and the elastic members 730 may be springs, rubber having elasticity, silicone, or the like. The shielding blocks 720 are connected to the inner water discharging disk 600 through the elastic members 730, so that the shielding blocks 720 can elastically move along the radial direction of the inner water discharging disk 600, and the shielding blocks 720 are used for shielding the corresponding sixth hole portions 434. For example, referring to fig. 15, when the shielding block 720 shields a part of the sixth hole 434, the other sixth hole 434 may be drained, and the shielding part sequentially shields the adjacent sixth hole 434 in the process that the inner drain pan 600 drives the shielding block 720 to rotate.

It will be appreciated that when the inner drain pan 600 rotates, the plurality of shielding blocks 720 may be driven to move in the track groove 440, for example, the shielding blocks 720 may extend away from the first axis under the elastic force of the elastic member 730, so as to shield the sixth hole 434. When the shutter block 720 moves from one track groove 440 to another track groove 440, that is, when the shutter block 720 is located between the two track grooves 440, the sixth hole portion 434 may be opened, and the shutter block 720 compresses the spring. With this arrangement, the fifth hole 433 can hold water for a long time, and the sixth hole 434 intermittently discharges water under the intermittent shielding of the shielding block 720, so that the water discharge device 1000 has a certain massage effect when discharging water.

It should be noted that, in the process that the inner water outlet tray 600 drives the shielding block 720 to rotate, since the first sealing ring is disposed between the outer water outlet tray 400 and the housing 100, the second sealing ring is disposed between the outer water outlet tray 400 and the inner water outlet tray 600, and the first sealing ring and the second sealing ring have elasticity. And gaps exist between the outgoing water tray 400 and the housing 100, and between the outgoing water tray 400 and the inner water tray 600 along the radial direction of the outgoing water tray 400, so that the outgoing water tray 400 can move within a small range. The shielding block 720 has an impact effect on the track grooves 440 when the shielding block 720 passes over the connection of the adjacent track grooves 440 under the elastic force of the elastic member 730. Therefore, the blocking piece 720 repeatedly impacts the inner wall of the track groove 440 during the rotation process, so that the outgoing water tray 400 vibrates, irregularities of water flow when the first water outlet 430 and the second water outlet 610 are used for discharging water can be increased, the direction of the water column is changed continuously, and more diversified feeling can be provided when the user is flushed, so that the shower massage experience of the user is provided.

For example, referring to fig. 16, the abscissa in fig. 16 represents the water inlet pressure, and the ordinate represents the vibration frequency of the outlet water tray 400, and as the water pressure increases, the vibration frequency of the outlet water tray 400 increases. When the number of teeth of the second gear 210 is greater than that of the third gear 330, the inner water outlet tray 600 and the outer water outlet tray 400 can be driven to do acceleration motion relative to the rotation speed of the impeller 200, and the transmission speed ratio is a. With a certain number of track grooves 440, the frequency of the shielding block 720 periodically pushing against the track grooves 440 increases with the increase of the water pressure, so that the outgoing water tray 400 forms low-amplitude and high-frequency vibration enhanced pulse outgoing water. When the number of teeth of the second gear 210 is equal to the number of teeth of the third gear 330, the rotational speeds of the inner water outlet tray 600 and the outer water outlet tray 400 are substantially the same as those of the impeller 200, and the impeller 200 plays a role in transmitting power, and the transmission speed ratio is B. Under the condition that the number of the track grooves 440 is fixed, the frequency of periodically propping against the track grooves 440 by the shielding block 720 increases along with the increase of the water pressure, so that the outgoing water tray 400 forms low-amplitude high-frequency vibrating pulse outgoing water. When the number of teeth of the second gear 210 is smaller than that of the third gear 330, the inner water outlet tray 600 and the outer water outlet tray 400 can be driven to do deceleration motion relative to the rotation speed of the impeller 200, and the transmission speed ratio is C. Under the condition that the number of the track grooves 440 is fixed, the frequency of periodically propping against the track grooves 440 by the shielding block 720 increases along with the increase of the water pressure, so that the outgoing water tray 400 forms low-amplitude high-frequency vibrating pulse outgoing water. Therefore, through different tooth ratios, the rotation speed of the inner water outlet disc 600 and the outer water disc 400 can be changed, so that the vibration frequency of the outer water disc 400 is changed, and the vibration frequency is adjusted to be proper according to actual conditions.

Referring to fig. 14, in the embodiment of the present invention, a first guiding surface 721 is disposed at an end of the shielding block 720 facing away from the inner water outlet tray 600, a second guiding surface 441 is disposed at a side of the track groove 440 facing the inner water outlet tray 600, that is, a sidewall of the track groove 440, and the shielding block 720 is configured to move between adjacent track grooves 440 through guiding cooperation of the first guiding surface 721 and the second guiding surface 441 during rotation of the inner water outlet tray 600 relative to the outer water outlet tray 400. The first guide surface 721 and the second guide surface 441 serve as guides for guiding the direction of the shielding block 720, and improve the guiding accuracy. For example, two first guiding surfaces 721 are disposed at one end of the shielding block 720 facing away from the inner water outlet disc 600, and the two first guiding surfaces 721 are disposed at an included angle and connected. The side wall of the track groove 440 comprises two second guiding surfaces 441 which are arranged at an included angle and are connected, and the second guiding surfaces 441 of two adjacent track grooves 440 are also arranged at an included angle.

Referring to fig. 14, in the embodiment of the present invention, a positioning groove 620 is formed along the outer periphery of the inner water outlet tray 600, an elastic member 730 is disposed in the positioning groove 620, one end of a shielding block 720 is connected to the elastic member 730 and is positioned and connected in the positioning groove 620, and the other end of the shielding block 720 protrudes out of the inner water outlet tray 600. Therefore, in the process that the inner water outlet disc 600 drives the shielding block 720 to rotate, the shielding block 720 can stretch and retract in the positioning groove 620 along the radial direction of the inner water outlet disc 600 under the action of the elastic force of the elastic member 730 through the guiding cooperation of the first guiding surface 721 and the second guiding surface 441, so that the sixth hole 434 is shielded or opened, and the pulsed water outlet is realized.

In the embodiment of the present invention, the inner diameter of the water outlet end of the fifth hole 433 is larger than the inner diameter of the water outlet end of the sixth hole 434, so that the diameter of the water column when the fifth hole 433 is discharged is larger than the diameter of the water column when the sixth hole 434 is discharged. When the water outlet device 1000 discharges water, water columns with different diameters are combined to discharge water, and meanwhile, the sixth hole part 434 discharges water in a pulse mode under intermittent shielding of the shielding block 720; the water column may also be spiral in the case where the inner and outer water trays 600 and 400 are rotated. Therefore, a certain massage effect can be achieved, and the shower experience of a user is improved.
