The first water outlet hole 131, the second water outlet hole 132, the third water outlet hole 133, and the fourth water outlet hole 134 of the water outlet structure 121, the second water outlet structure 122, the third water outlet structure 123, and the fourth water outlet structure 124 are connected to the first water inlet cavity 111, and the fixing seat 11 is provided with a spring positioning bead, and the spring positioning bead includes a spring 113 and a positioning marble 114. The water diversion body 12 is provided with three positioning holes 125 that cooperate with the spring positioning bead. When the water diversion body 12 is rotated relative to the fixing seat 11, the spring positioning bead is fixed with the three positioning holes 125 in turn, and the second water outlet structure 122, the third water outlet structure 123, and the fourth water outlet structure 124 are connected to the second water inlet cavity 112 in turn. It should be noted that in this embodiment, the water outlet net 13 is made of metal, but it is not limited to this, and can also be injection molded.

[0057] The first water inlet cavity 111 is located in the middle of the fixing seat 11, the first water outlet structure 121 is cylindrical and located in the middle of the water diversion body 12, and the first water outlet holes 131 include a plurality of holes and are all located in the middle of the water outlet net 13. Specifically, the first water outlet holes 131 are evenly distributed radially with the midpoint of the water outlet net 13 as the center. When the water outlet assembly 10 of the present invention discharges water through the first water inlet cavity 111, the first water outlet structure 121, and the first water outlet holes 131, the water outlet mode of the water outlet assembly 10 is concentrated water, such as Figure 5 As shown, the concentrated water here can be bubble water, soft water or pinhole water.

[0058] The second water inlet chamber 112 includes two, which are symmetrically arranged on both sides of the first water inlet chamber 111, the second water outlet structure 122, the third water outlet structure 123, and the fourth water outlet structure 124 each include two, which are symmetrically arranged on both sides of the first water outlet structure 121, and the second water outlet structure 122 is a blade water outlet structure. The water outlet end of the blade water outlet structure passes through the second water outlet hole 132 and extends out of the water outlet net 13. When the water outlet component 10 of the present invention passes through the second water inlet chamber 112 and the second water outlet structure 122 to discharge water, the water outlet mode of the water outlet component 10 is blade water, such as Figures 6 to 8 shown.

[0059] like Figures 7 and 8 As shown, the blade water outlet structure includes a third water inlet chamber 1221 in the shape of a semi-ellipsoid or a hemisphere, and an inverted V-shaped groove 1222 is provided at the bottom end of the third water inlet chamber 1221, and the two inclined surfaces of the V-shaped groove 1222 are symmetrical about the axis of the third water inlet chamber 1221, and the V-shaped groove 1222 is connected with the third water inlet chamber 1221 to form a narrow and long water outlet nozzle 1223, and the water trace sprayed out through the water outlet nozzle 1223 is in the shape of a narrow and long strip, and the angle between the two inclined surfaces of the V-shaped groove 1222 is α, and α is 90 degrees. The water flows into the blade water outlet structure, and then is ejected from the water outlet nozzle 1223 formed by the V-shaped groove 1222 at the bottom of the water outlet cavity. Since the water flows from a larger cavity suddenly through a small cross-section, the water flow will suddenly accelerate at this time, and then pass through the water outlet nozzle 1223 formed by the V-shaped groove 1222, centrifugal force will be generated at this time. According to the theory of fluid mechanics, the water flow will be differentiated by the centrifugal force and guided into sheet-like water splashes, thereby forming blade water with greater impact force and wider coverage.

[0060] The third water outlet structure 123 is a bulb water outlet structure, the outlet end of the bulb water outlet structure passes through the third water outlet hole 133 and extends out of the water outlet net 13, the bulb water outlet structure includes an impeller 123a, and the impeller 123a has a fan-shaped baffle. When the water outlet component 10 of the present invention passes through the second water inlet chamber 112 and the third water outlet structure 123 to discharge water, the water flow forms a spiral water flow under the guidance of the impeller 123a, and the water flow has a certain flow rate. Finally, the water outlet component 10 flows out bulb water with a large impact force, such as Fig. 9 , Fig.10 shown.

[0061] The fourth water outlet structure 124 is a through hole provided on the water diversion body 12, and the fourth water outlet structure 124 is connected to the fourth water outlet hole 134. The fourth water outlet hole 134 includes a plurality of holes and is evenly arranged along the periphery of the water outlet net 13. The fourth water outlet hole 134 includes two evenly arranged inner and outer circles, and its aperture is small. When the water outlet assembly 10 of the present invention passes through the second water inlet cavity 112 and the third water outlet structure 123 to discharge water, the water outlet mode of the water outlet assembly 10 is shower water, such as Fig.11 shown.

[0062] The outer wall of the fixing seat 11 is provided with a mounting thread 115. The arrangement of the mounting thread 115 makes it easy to disassemble the water outlet assembly 10. As long as the corresponding shower head is provided with an internal thread 21 matching the mounting thread 115, it can be quickly disassembled and assembled, which is convenient and quick. In this embodiment, a sealing ring 16 is provided between the first water outlet structure 121, the second water outlet structure 122, the third water outlet structure 123 and the water outlet net 13, and a sealing ring 16 is provided between the water outlet net 13 and the gland 14.

[0063] Reference Figures 5 to 13 As shown, a shower head includes a shower head body 20 and the above-mentioned water outlet assembly 10, wherein the shower head body 20 has an internal thread 21 that is matched with the mounting thread 115 on the fixing seat 11, and the shower head body includes a first water outlet channel 22 and a second water outlet channel 23 that can be switched with each other, a switching mechanism 24 that controls the first water outlet channel 22 and the second water outlet channel 23 to switch with each other, and a switching channel 25 that is connected to both the first water outlet channel 22 and the second water outlet channel 23, wherein the switching channel 25 is connected to the water inlet channel of the shower head body, and the switching mechanism 24 is arranged in the switching channel 25, and the switching mechanism 24 includes a sealing shaft guide sleeve 241 that is sealed and installed, and a sealing shaft guide sleeve 241 that is arranged through the sealing shaft guide sleeve 24 1 and can axially reciprocate relative to the sealing shaft guide sleeve 241, the sealing shaft 242 has a sealing end located in the switching channel 25 and an operating end opposite to the sealing end, the sealing end has a sealing structure that movably seals the connection between the switching channel 25 and the first water outlet flow channel 22 and the second water outlet flow channel 23, a return spring 243 is provided between the sealing structure and the sealing shaft guide sleeve 241, and the two ends of the return spring 243 respectively abut against the sealing structure and the sealing shaft guide sleeve 241, a button 244 is provided on the shower body, and the button 244 can be flipped on the shower body, and the operating end of the sealing shaft 242 is linked to the button 244.

[0064] The switch mechanism 24 of the shower body is an automatic reset structure, and its automatic reset principle is: Figure 5As shown, the sealing structure is blocked at the connection between the switching channel 25 and the second water outlet channel 23 under the action of the reset spring 243. At this time, the water in the shower body flows out through the switching channel 25 and the first water outlet channel 22. At this time, if the water source is cut off, the shower is always in this state (initial state). When the water source is turned on again, the shower still discharges water through the first water outlet channel 22. To switch the state, press the button 244 when the shower is filled with water. Figure 6 , Fig. 9 , Fig.11 As shown, the button 244 flips, driving the sealing structure of the sealing shaft 242 to move to block the connection between the switching channel 25 and the first water outlet channel 22. At this time, the water flows out through the switching channel 25 and the second water outlet channel 23. In this state, the return spring 243 is compressed. At this time, the sealing structure is under the pressure of the water flow, and the sealing structure overcomes the elastic force of the return spring 243 and is always blocked at the connection between the switching channel 25 and the first water outlet channel 22. At this time, if the water source is cut off, the pressure of the water flow on the sealing structure is eliminated, and the sealing structure returns to the initial position under the action of the return spring 243, that is, the sealing structure is blocked at the connection between the switching channel 25 and the second water outlet channel 23. At the same time, the sealing shaft 242 and the button 244 return to the initial position. When the water source is turned on again, the shower is also in the initial state, that is, water flows out through the first water outlet channel 22, thereby realizing automatic resetting of the sealing structure.

[0065] After the water outlet assembly 10 of the present invention is installed with the shower body 20, the first water outlet channel of the shower body 20 is communicated with the first water inlet chamber 111 of the water outlet assembly 10, and the second water outlet channel is communicated with the second water inlet chamber 112 of the water outlet assembly 10. When the shower is switched to the first water outlet channel to discharge water, the water outlet assembly 10 discharges concentrated water through the first water outlet hole 131. When the shower is required to discharge bulb water, blade water or shower water, the switching mechanism 24 is used to switch the shower to the second water outlet channel to discharge water, and the water dividing body 12 is rotated until the second water inlet chamber 112 is connected to the corresponding water outlet structure, so that bulb water, blade water or shower water can be obtained. A common shower head with two water channels on the market is equipped with the water outlet assembly 10 of the present invention, so that a common shower head has four water outlet modes to meet various usage requirements. In addition, the automatic reset function of the switching mechanism 24 of the shower head body 20 in this embodiment ensures that after the shower head is cut off from the water source and turned on again, the shower head is always in the initial state, that is, water is discharged through the first water outlet channel 22, and the shower head discharges concentrated water. Concentrated water is usually the most commonly used water spray form in kitchen showers, such as bubble water, soft water or pinhole water, which can effectively prevent splashing.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
