the flow dividing channel 122 includes a restriction section 122a, where at least one place of the restriction section 122a has a cross-sectional area smaller than the area of the communication port and the water outlet (at least one place of the restriction section 122a has a cross-sectional area smaller than the area of the communication port and the water outlet), that is, the flow rate of at least one place of the restriction section 122a is smaller than the flow rate of the communication port and the water outlet, that is, the place of the smallest cross-sectional area of the flow dividing channel 122 is located in the restriction section 122a, so that the liquid forms turbulence at the outlet of the flow dividing channel 122, that is, the primary kinetic energy of the liquid flowing out from the water outlet 101.
It should be noted that, the three of N water outlets, N sub-channels, and N communication ports are in one-to-one correspondence, i.e., the N sub-channels are respectively connected with the N groups of water outlets and the communication ports in one-to-one correspondence, i.e., different sub-channels are connected with different water outlets and communication ports, and there is no same water outlet or communication port connected with two sub-channels at the same time.
According to the water drinking disc, the shrinkage limiting section is arranged on the diversion channel, so that turbulence is formed at the water outlet, water flow entering the water drinking disc has certain initial kinetic energy, so that the liquid in the water drinking disc is in a flowing state, power capable of taking away foreign matters (such as dirt and the like in the water drinking disc, which can comprise any solids insoluble in water) is generated, and the water quality in the water drinking disc is improved.
When N is greater than or equal to 2, the water inlet 121a is connected with the communication port 121b in series, that is, the N sub-channels 122 are connected with the main channel 121 in parallel through the communication port 121b, and the main channel 121 is used for injecting water into the N sub-channels 122 almost simultaneously, so that the N water outlets 101 are used for discharging water almost simultaneously.
According to a preferred embodiment of the present invention, the bypass channel 122 extends from the communication port 121b to the restriction 122a, and the cross-sectional area gradually decreases, and then extends from the restriction 122a to the water outlet 101, and the cross-sectional area gradually increases, that is, the cross-sectional area in the bypass channel gradually decreases and then increases along the direction of fluid flow, and the place where the cross-sectional area is the smallest is located in the restriction 122a. So set up, on the one hand, guarantee the passageway stability of subchannel 122, avoid the too big impact force that the passageway wall surface received somewhere, on the other hand, avoid the fluid to produce the noise when passing through the subchannel, improve the result of use of drinking water dish.

Preferably, the ratio of the opening area of the communication opening 121b to the minimum cross-sectional area of the restriction 122a is 1.3:1 or more, so as to avoid the formation of a small initial kinetic energy of the water flow at the water outlet.
In order to improve the stability of the fluid in the water outlet channel 12, the connection between the main flow channel 121 and the diversion channel 122 adopts arc transition, and also avoids the vortex formed at the connection position of the main flow channel 121 and the diversion channel, which affects the fluency of the fluid flow in the water outlet channel.
In order to avoid splashing of the water flowing out of the water outlet 101, the opening direction of the water outlet 101 is tangential to the wall of the water trough 11, that is, the fluid flowing out of the water outlet 101 is tangential to the wall of the water trough 11, so that the fluid flowing out of the water outlet 101 obtains a centripetal force tangential to the wall of the water trough 11, so that the fluid entering the water trough 11 can form vortex therein, and the fluidity of the liquid in the water trough 11 is improved. Preferably, when N is greater than or equal to 2, the opening directions of all the water outlets 101 are clockwise or anticlockwise so that N fluid columns entering the water trough 11 form vortexes with identical spiral directions, and the fluidity of the liquid in the water trough 11 is further improved. Further preferably, the N water outlets 101 are located at the same height in the water trough 11 and are evenly distributed.

Preferably, the shape of the main flow channel 121 matches with the shape of the drinking water tray 1, and in this embodiment, the shape of the main flow channel 121 is a circular ring.
The shape and the extending direction of the N sub-channels are the same, and the same extending direction means clockwise rotation or counterclockwise rotation. Preferably, the arcs of the N sub-channels are located substantially on the same circle to better form a liquid vortex in the trough 11.
