The above embodiment is the most basic solution of the present application, and has been able to solve the problems raised in the background art and achieve the object of the present invention. In the following, the performance of the above basic scheme is further improved to achieve better performance.

[0048] Further, the first engaging portion may be a circumferentially disposed guide groove 13, and the second engaging portion may be a convex portion 28, and the convex portion 28 of the water dividing body 20 is mounted on the casing 10 In the slot 13. Further, it may be alternately arranged, that is, the first mating portion may be a boss portion, and the second mating portion may be a guide groove.

[0049] As can be seen from the above description, the first engaging portion and the second engaging portion may be any structure capable of achieving a mutually restricting rotation angle.

[0050] Further, the inner wall of the casing 10 is provided with a vertical fixing groove 14, and the outer wall of the water guiding body 30 is provided with a vertical fixing rib 36; or, the inner wall of the casing 10 is provided with a vertical fixing rib, and the water guiding body 30 The outer wall is provided with a vertical fixing groove; the housing 10 and the water guiding body 30 are fixed by a mating connection of the fixing groove 14 and the fixing rib 36.

[0051] As can be seen from the above description, the fixing groove and the fixing rib cooperate to restrict the circumferential rotation between the housing and the water guiding body.

Further, a seal ring 60 is attached between the outer wall surface of the top end of the water guiding body 20 and the casing 10 with reference to FIGS. 2 and 10 and FIG.

[0053] As can be seen from the above description, the provision of a sealing ring between the water guiding body and the casing prevents the water from overflowing between the water guiding body and the water dividing body and continuing to escape outwardly between the casing and the water guiding body.

[0054] Further, referring to FIG. 2, the inner edge of the water outlet end 12 of the housing 10 is provided with a convex portion 15, and the outer side wall of the first water outlet channel 31 of the water guiding body 30 is provided with a recessed portion 37. The housing 10 is engaged with the recessed portion 37 of the water guiding body 30 by the boss portion 15. Specifically, the boss portion 15 may be provided as a boss portion having a transition slope to be more easily fitted to the recess portion 37.

[0055] Further, referring to FIG. 10, or the first annular vertical plate 23 is provided with an internal thread 吋, the outer casing 10 covers the outer surface of the first annular vertical plate; or the first annular vertical plate 23 The external thread 吋 is provided, and the cover height of the outer casing 10 is offset from the external thread.

[0056] As can be seen from the above description, the above structure can match different water discharge devices, and the applicability is stronger. When the external thread 吋 is set, after the water dividing body and the water outlet device are locked, the outer casing is covered by the outer thread due to the covering height, so There is a certain spacing between the settings to ensure a smooth rotation of the housing.

[0057] Further, in combination with FIG. 3 to FIG. 5, a plurality of the flow guiding holes 21 may be disposed and uniformly distributed in the water dividing body.

The water inlet 311 of the first water outlet channel 31 and the water inlet 321 of the second water outlet channel 32 are respectively disposed in a plurality of annular channels and are uniformly distributed on the top surface of the water guiding body 30, the first water outlet. The water inlet 311 of the channel 31 and the water inlet 321 of the second water outlet channel 32 are adjacently arranged, and the water outlet 312 of the first water outlet channel 31 is disposed around the water outlet 322 of the second water outlet channel 32; the water inlets 311 and 321 are in the water guiding body The distribution position on the 30 is matched with the flow guiding hole 21 on the water dividing body 20, and the area of the flow guiding hole 21 is smaller than the area of the water inlets 311, 321 .

[0058] As can be seen from the above description, the arrangement of the plurality of flow guiding holes and the water inlet allows the water flow to be transmitted more rapidly and stably downward. In the solution shown in Figures 1 to 6, eight rectangular flow guiding holes are provided, and correspondingly, water inlets and eight inlets of the first sector of the eight fan-shaped water outlets are provided on the water guiding body. The inlet of the fan-shaped second outlet passage. The setting method of the above-mentioned "adjacent staggered arrangement" is as shown in FIG. 6, that is, the water inlet of a first water outlet channel, the water inlet of a second water outlet channel, the water inlet of a first water outlet channel, and the inlet of a second water outlet channel. The nozzles are arranged adjacently.

[0059] Specifically, referring to FIG. 3, the water split body 20 has a better structure: a second annular vertical plate 22 is disposed on a side of the water dividing body 20 on the water guiding hole 21 toward the center of the water dividing body disk surface, and two adjacent ones are adjacent to each other. A baffle 24 connecting the second annular riser 22 and the first annular riser 23 is disposed between the guide holes 21, and the height of the second annular riser 22 is greater than the first annular riser 23 and the baffle twenty four.

[0060] It can be seen from the above description that the inner first annular vertical plate and the baffle constitute an independent water inlet space of the diversion hole, and the water flow first flows into the second annular vertical plate to be fully filled before flowing into the water inlet space. Therefore, the water entering the independent space will be relatively stable, and is not affected by the front inlet water flow condition, thereby ensuring a continuous negative pressure at the outlet of the diversion hole to continuously take in air for mixing.

[0061] Further, referring to FIG. 1, FIG. 2 and FIG. 4, an annular first rectifying net 50 may be further included, and the water discharge area of the first water outlet passage 31 is contracted along the water inlet 311 toward the water outlet 312, and the water outlet is retracted. A protruding diffuser block 313 is disposed in the 312. The first rectifying net 50 is installed in the water outlet 312 of the first water outlet passage 31 at a side of the diffuser block 313 near the water outlet 312.

[0062] As can be seen from the above description, the gradually shrinking water outlet channel can form a higher pressure effluent water flow, and the diffusing flow block can disperse the water, so that the water flow tends to be gentle, ensuring that the final effluent water is more tidy, Du After the high-pressure water is discharged, the water column is scattered. The diffuser block can also reduce the impact of the high-pressure water on the rectifying net. After the high-pressure water flows through the diffusing flow of the diffusing block, it is rectified by the rectifying net, and the water is more tidy.

[0063] Further, with reference to FIG. 1 to FIG. 3, a J-shaped hook 25 may be further disposed on the lower end surface of the water-dividing body 20, and the hook body 251 of the hook 25 is disposed outward. The hook rod 252 of the connecting hook body 251 is provided with a convex point 253 facing outward; the water guiding body 30 is provided with an annular plate 34 fixedly connected to the plurality of the first water outlet channel 31 and the second water outlet channel 32. On the wall surface of the water inlets 311, 321 , the inner wall of the annular plate 34 is spaced apart from the plurality of grooves 341 matched with the above-mentioned bumps 253, and the position of each groove 341 on the annular plate 34 corresponds to each of the annular plates 34. The water inlet 311, 321 of the outer wall; the hook body 251 of the hook 25 is engaged with the lower end surface of the annular plate 34 for rotatably connecting the water dividing body 20 and the water guiding body 30, and the bump 253 is embedded in the groove 341

[0064] wherein the rubber hook sleeve 26 is disposed in the space surrounded by the hooks 25. The lower end of the rubber plug sleeve 26 is provided with a rectifying column 27 extending into the lower end of the second water flow channel 32.

[0065] It can be seen from the above description that the above-mentioned connecting structure can realize the rotational connection between the water dividing body and the water guiding body; during the rotation, the groove rotates with the water guiding body to push the hook rod inwardly through the convex point until the other groove is embedded. On the bump, the cooperation of the bump and the groove allows the user to have a gear position feeling in the rotating water guiding body, that is, each time the groove moves from one convex point and the other groove is embedded in the convex point, the user can The feedback of whether the rotation is in place is obtained from the change of the magnitude of the force applied; meanwhile, since the position of each groove on the annular plate corresponds to each water inlet located on the outer wall of the annular plate, the bump is from a concave every time of rotation After the trough is transferred to the next groove to complete the gear shift, the diversion hole is completely rotated from the current outlet passage to the other outlet passage, thereby changing the water discharge. In addition, by providing a rubber stopper in the hook, the rotating water guiding body is pressed inwardly by the convex point, and the rubber stopper is pressed, and the pressing process is softened due to the elasticity of the rubber stopper. The switching feel is improved, and on the other hand, the support of the rubber stopper to the hook rod can also make the hook have a longer service life. In addition, the rectifier column is integrally disposed at the lower end of the rubber plug sleeve and extends into the lower end of the second water outlet passage, thereby achieving better rectification.

[0066] Obviously, the connection manner in the above improvement is not unique to the basic solution of the present application, and the hook may be disposed on the water guiding body to set the groove structure on the water-dividing body, or the hook may be hooked. Inward setting, etc., are all improvements that are easy to think of. And, the diameter and the number of the rectifying columns can be set according to actual conditions. In the embodiment shown in FIG. 1, the rectifying columns are provided with six. [0067] Further, referring to FIG. 2, FIG. 6, and FIG. 7, the water dividing body 20 in the modification may be connected to the inner surface of the side wall of the top end of the water guiding body 30 through its circumference, with emphasis on the circumference and the side. A sealing ring 60 is provided between the inner faces of the walls to form a sealed connection.

[0068] As can be seen from the above description, the sealing ring is provided so that the water flow cannot overflow through the contact surface of the water dividing body and the water guiding body, and the water leakage can be prevented from affecting the use effect.

[0069] Further, referring to FIG. 1, FIG. 2 and FIG. 5, the solution may further include a second water outlet net 70, which includes an outer ring net 71 and an inner ring net 72, and the outer ring net 71 surrounds the inner ring. The mesh 72 is disposed in a ring shape, and the horizontal cross-sectional shape of the water outlet hole of the outer ring net 71 can be set to a C shape and the water discharge area is contracted from the inside to the outside, and the outer ring net 71 is docked to the water outlet 312 of the first water outlet channel 31, The inner ring net 72 is docked to the water outlet 322 of the second water outlet channel 32.

[0070] As can be seen from the above description, the installation of the water outlet network can further improve the effluent effect of the water flow.

[0071] The second water outlet net 70 may further include a second rectifying net 73. The upper surface of the inner ring net 72 is provided with a plurality of convex supporting portions 721 to support the second rectifying net 73.

[0072] As can be seen from the above description, the supporting portion is provided to support the second rectifying net to create a certain gap between the second rectifying net and the inner ring net, so that the second rectifying net is opposite to the water flow from the second water outlet channel. The rectifying action is better, thereby further improving the effluent effect after passing through the water outlet net.

Further, for the connection scheme of the second water outlet net 70 and the water guiding body 30, an annular partition wall 74 may be disposed between the outer ring net 71 and the inner ring net 72, and a convex body is disposed on the partition wall 74. 741; matchingly, a recess 351 is formed on the partition 35 between the water outlet 312 of the first water outlet passage 31 and the water outlet 32 2 of the second water outlet passage 32 on the water guiding body 30, on the partition wall The protrusion 741 is loosely fastened in the concave portion 351

[0074] It can be seen from the above description that the connection between the second water outlet mesh and the water guiding body adopts a buckle joint and an interference fit relationship, which can save the welding step or the rubber seal, thereby achieving the advantages of convenient assembly and material saving, and the cooperation is achieved. The seal of the relationship is equivalent to the sealability of the rubber ring, and there is no problem of water leakage.

[0075] wherein, the solution shown in FIG. 1 and FIG. 2 may further include a water inlet assembly 40, the water inlet assembly 40 includes a filter net 41, a flow control elastic piece 42 and a first water outlet net 43; the filter net 41 is convex at the center and passes through The circumference is fixed to the upper end of the first water outlet net 43, the first water outlet net 43 is fixed to the upper end of the water dividing body 20, and the flow control elastic piece 42 is mounted on the first water outlet net 43 and located in the cavity formed by the central protrusion of the filter net 41, a water outlet 43 The water outlet hole 431 is provided at the center, and the water outlet hole 431 faces a portion of the water dividing body 20 that is enclosed by the second annular vertical plate 22. The water inlet assembly is arranged above the water dividing body to pre-modulate the water flow: the filter first filters the impurities in the water to prevent the impurities from damaging the subsequent functional components in the device; the flow control shrapnel can control the flow rate so that the water flows through the flow shrapnel It is stable and does not have undulations due to changes in water pressure (the specific working principle is that the greater the water pressure, the larger the shrapnel deformation, the smaller the water outlet below the shrapnel; the smaller the water pressure, the smaller the shrapnel deformation, the water flow under the shrapnel The larger the outlet; the water pressure is inversely proportional to the water outlet, thus acting to stabilize the water flow); Finally, the first outlet network concentrates the water flow in the center of the outlet hole and the water flow falls into the second part of the water body. It accumulates in the space enclosed by the annular riser, and when it is full, it overflows into the guide hole.
