Technical Field

After rectification and buffering, the impact force of the clear water decreases, and there will be no splashing of water. At the same time, it is different from the soft and weak bubble water, so it has a certain impact force; the water outlet angle and the water outlet slope can effectively avoid the sticky flow of the water flow, so that the water flow will not adhere to the side wall of the water outlet, affecting the water outlet shape of the clear water; the first rectifying net and the first rectifying sheet are fixed on the first On the first annular step surface inside the shell, there is a first buffer zone between the first rectifying piece and the water outlet of the first shell; the first diverter body has a diverter port, and in one use, the diverter port is annularly distributed on the outer peripheral side of the first diverter body, and a water retaining portion 143 is formed on the inner periphery of the diverter port, and the water retaining portion is used to slow down the speed of water flowing into the first shell; the first rectifying net has a plurality of water outlet holes, and the water outlet holes are arranged in a hexagonal shape; the first rectifying piece is a stainless steel filter screen or a nylon filter screen, and also has a plurality of water outlet holes; the first annular step surface and the first buffer step are used to limit the height of the first rectifying piece in the first shell to form a first buffer zone.
[0044] Wherein: the bubble water outlet module includes a hollow third shell 310, a third buffer zone 311 is arranged in the third shell, the third buffer zone can be connected with the water inlet end of the third shell, a third buffer step 312 is arranged in the third shell, the third buffer step is arranged at the bottom of the third buffer zone, the third buffer step is located on the periphery of the water outlet 313 of the third shell, the third classroom water outlet is coaxially arranged with the third buffer zone and the third buffer step, the cross-sectional area of the third buffer zone is larger than the cross-sectional area of the water outlet of the third shell; the diameter of the water outlet of the third shell gradually increases along the water outlet direction so that The water inlet end of the third shell water outlet forms a sharp angle 314, and the sharp angle is an acute angle.

The water flowing out of the third shell water outlet can impact one end face of the water baffle, and the water flow with a certain impact force impacts one end face (upper end face) of the water baffle, so that a bubble water (also known as light bulb water, lampshade water) with a good shape can be formed.
[0045] Preferably, one end face of the water baffle is a plane 321, which can be perpendicular to the direction of water flow impact, and the outer peripheral edge 322 of the plane is a right angle, which can ensure that the water flow vertically impacts the plane and a uniform and good water jump phenomenon occurs, thereby forming an excellent bubble water shape.
[0046] Furthermore, it also includes a third rectifying net 330 located in the third shell, the middle part of the third rectifying net is connected to one end of the connecting rod 340, the other end of the connecting rod can extend out of the outside of the third shell, and the other end of the connecting rod is matched and connected with one end face of the water baffle, so that there is a certain distance between the plane and the water outlet of the third shell, which is convenient for forming an excellent bubble water shape. A third annular step surface 316 is arranged in the third shell, and the lower end face of the third rectifying net abuts on the third annular step surface, and the third rectifying net is coaxially arranged with the connecting rod and the water baffle.

[0050] Preferably, the cross-sections of the water inlet and the water outlet of the water outlet are elliptical, and the size of the water outlet gradually increases along the water outlet direction. Figure 3 The dotted line is the outlet end of the water outlet. The arc edge makes the outermost water splash of the sheet water have more water flow ratio, and at the same time, no sharp corners are generated to cause excessive squeezing of the outer water flow, thus preventing the sheet water from spreading outward and splashing.
[0051] Furthermore, the maximum diameter of the chamber is larger than the long axis size of the water inlet end of the water outlet, and the long axis size of the water outlet channel is larger than the maximum diameter of the chamber, and even larger than the major diameter of the second buffer zone. The water inlet end of the water outlet is connected to the middle of the chamber along the water flow direction, and the chamber can be coaxially arranged with the water outlet. A second buffer step 214 is also arranged in the second shell, and the second buffer step is located on the outer peripheral side of the opening of the water inlet end of the chamber.

When the second rectifying net is installed in the second shell, the second protrusion can be matched and connected with the second groove, and at the same time, radial rotation of the rectifying net can be avoided.
[0055] Specifically, the sheet water outlet module is as follows: the water flows into the second shell, passes through the second rectifying net and the second rectifying sheet, and then enters the second buffer zone, thereby forming a laminar flow state (making the water film of the sheet water longer) and then flows out from the outlet.
