[0015] The eleventh technical solution is based on the tenth technical solution, wherein the first switching mechanism includes a reset member, a blocking member and a water diversion valve, the reset member is located between the blocking member and the main body, the water diversion valve is sealed and fixed to the first valve cavity, the water diversion valve is circumferentially provided with a water diversion port, and the water diversion port is connected to the first water outlet channel; the blocking member is sealed and plugged into the water diversion valve, and is suitable for moving axially relative to the water diversion valve along the first valve cavity when subjected to external force to block the second water outlet channel, connect the water inlet end of the first valve cavity with the water diversion port, and compress the reset member to deform it; when the external force is released, the reset member is deformed and restored, driving the blocking member to reset to block the water diversion port, and connect the water inlet end of the first valve cavity with the second water outlet channel.

[0016] The twelfth technical solution is based on the first technical solution, wherein the water outlet assembly also includes a second switching mechanism, the second switching mechanism is provided with a water inlet and a switching valve, and the switching valve is installed on the water inlet; the main body is also provided with a water passage and a third water outlet channel, and the water passage is suitable for connecting to the first water outlet channel; the main body is rotatably connected to the second switching mechanism to control the switching valve to switch the water inlet to connect to the water passage or the third water outlet channel.

[0017] The thirteenth technical solution relates to a water outlet device, which comprises a water outlet body and a water outlet component as described in any one of the first to twelfth technical solutions, wherein the water outlet component is arranged at the water outlet end of the water outlet body.

[0018] Compared with the prior art, the above technical solution has the following beneficial effects:

[0019] In the first technical solution, the water outlet assembly includes a body, the body is provided with a first water outlet channel and an air storage chamber, the first water outlet channel has a first water outlet, the air storage chamber is provided with a first through hole, the first through hole is located at the front end of the first water outlet along the water flow direction, and the first through hole connects the air storage chamber and the first water outlet channel so that the water flow squeezes part of the gas in the first water outlet channel into the air storage chamber; thus, when the water outlet assembly is used for the first time, the water flows into the first water outlet channel, the gas in the first water outlet channel is driven by the water flow, a part of it is discharged from the first water outlet, and a part of it enters the air storage chamber through the first through hole, when the water flows through the first through hole, a part of the water flows into the air storage chamber and mixes with the gas in the air storage chamber, when the water-gas mixture in the air storage chamber and the pressure of the water flow in the first water outlet channel reach equilibrium, the water flow no longer flows into the air storage chamber, and flows out directly from the first water outlet. Since the air storage chamber accommodates a part of the gas discharged from the first water outlet channel, the amount of gas discharged through the first water outlet is reduced, thereby reducing the disturbance of the water column caused by the gas discharge in the water outlet channel. Compared with the prior art, the present invention adopts a structure in which an air storage cavity is arranged in the main body, thereby improving the user experience.

[0020] In the second technical solution, at least one bend is set in the first water outlet channel to increase the flow resistance of the water along the first water outlet channel, reduce the flow rate of the water reaching the first water outlet, and make the gas in the water channel mix with the water as much as possible, so that the water column is softer and the experience is better; the first through hole is facing the direction of the water flow, which is more conducive to the water flow driving the gas in the first water outlet channel to enter the air storage chamber, and flow into the air storage chamber to mix with the gas.

[0021] In the third technical solution, the water outlet chamber divides the first water outlet channel into channel A and channel B which are interconnected. Channel A is connected to the first water outlet, and channel B is connected to the air storage chamber. The flow cross-sectional area of ​​the water outlet chamber is larger than the cross-sectional areas of channels A and B, which has the effect of further decelerating and converging the water flow flowing in from channel B, and has a certain acceleration on the water flow flowing into channel A, which is beneficial to maintaining the stability of the water column when water flows out of the first water outlet.

[0022] In the fourth technical solution, the water outlet cavity structure allows water to flow from channel B into the second cavity, and then be divided into two or more flow channels through the second through hole and then enter the first cavity, making the water flow smoother.

[0023] In the fifth technical solution, the first cavity includes an inner cavity and an outer cavity which are interconnected. The outer cavity surrounds the inner cavity to form a cavity-in-cavity structure. The inner cavity is connected to channel A, and the outer cavity is connected to the second through hole. Water flows into the outer cavity from the second through hole, and then flows into the inner cavity to enter channel A. Since the flow cross-section of the inner cavity is smaller than the flow cross-section of the outer cavity, the inner cavity converges the incoming water flow, forming concentrated water upwelling into channel A, which increases the flow velocity when the water enters channel A, and can maintain the integrity of the water column out of the first water outlet when the water pressure is low.

[0024] In the sixth technical solution, when water flows from channel B into the second cavity, since the second plug post extends toward channel B, the water flow is blocked by the second plug post and slowed down, thus becoming smooth.

[0025] In the seventh technical solution, the grille further rectifies and converges the water flow into the outlet cavity to form a soft outlet water column.

[0026] In the eighth technical solution, the filter net can rectify the water flow and filter out impurities in the water, making the water column from the first water outlet healthier and clearer.

[0027] In the ninth technical solution, the flow limiter can limit the flow when the water flow is relatively large, so as to achieve the effect of stabilizing the water column.

[0028] In the tenth technical solution, a first valve chamber is provided and a first switching mechanism is installed to switch between the first water outlet channel and the second water outlet channel, so as to diversify the functions of the water outlet component.

[0029] In the eleventh technical solution, the blocking member cooperates with the reset member to move the blocking member axially along the first valve cavity to switch the water inlet end of the first valve cavity to connect to the first water outlet channel or the second water outlet channel. The structure is relatively simple and easy to press.

[0030] In the twelfth technical solution, the main body is rotatably connected to the second switching mechanism to control the second switching mechanism to switch the water inlet to the water channel or the third water outlet channel, so that the water outlet component integrates more functional water outlets and has a compact structure.

[0031] In the thirteenth technical solution, the water outlet device includes the water outlet component described in any one of the first to twelfth technical solutions, and has corresponding technical effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] See also Fig.19 , 20The figure shows a schematic diagram of the first state and a schematic diagram of the second state of the water outlet assembly in this embodiment when the first switching mechanism 4 is used. As shown in the figure, when the button 41 is pressed against one end of the blocking member 43, the button 41 rotates relative to the main body 21, and drives the blocking member 43 to move axially relative to the valve cavity of the water diversion valve 42, so that the blocking portion 434 blocks the water outlet hole 254 of the first valve cavity 25, thereby blocking the second water outlet channel 212, and makes the water diversion port 4213 communicate with the water inlet hole 253 of the first valve cavity 25, thereby connecting the water channel 211 and the first water outlet channel 24. At this time, the water flow back pressure acting on the blocking portion 434 causes the blocking member 434 to The spring force deforms the first water outlet channel 24, and when the button 41 is released, the water passage 211 and the first water outlet channel 24 remain in communication; at this time, water flows from the water passage 211 into the B channel 242 of the first water outlet channel 24 through the water inlet hole 253 and the water diversion port 4213, and flows through the air storage chamber 23; when used for the first time, since there is gas in the first water outlet channel 24, the gas is driven by the water flow, and part of the gas flows into the air storage chamber 23, and part of the gas continues to flow through the water outlet chamber 26, the A channel 241, and finally flows out of the first water outlet 2 21 is discharged; part of the water flow flows into the air storage chamber 23 until the pressure of the air storage chamber 23 and the first water outlet channel 24 is balanced, and the rest of the water flow continues to flow through the water outlet chamber 26 and the A channel 241, and finally flows out from the first water outlet 221 at an angle, forming a stable water column, which is convenient for rinsing the mouth; when the button 41 is pressed away from the end of the blocking member 43, the button 41 rotates in the opposite direction relative to the main body 21, driving the blocking member 43 to move in the opposite direction, and the blocking portion 434 blocks the water diversion port 4213, connecting the water inlet hole 25 of the first valve chamber 25. 3 and the water outlet hole 254, thereby connecting the water channel 211 and the second water outlet channel 212, blocking the first water outlet channel 24, and the spring deformation is restored; water flows from the water channel 211 through the water inlet hole 253 through the first valve chamber 25, and enters the second water outlet channel 212 from the water outlet hole 254, and the water flow can be controlled by operating the bubbler; or the water inlet end of the water channel 211 is closed, so that the back pressure of the water flow acting on the blocking part 434 is released, the spring deformation is restored, the blocking member 43 is driven to move in the opposite direction, and the button 41 is driven to reset. As other prior art documents have already described in detail the use of the second switching mechanism 5, it will not be repeated here.

[0079] Compared with the prior art, this embodiment has the following beneficial effects:

[0080] In this embodiment, the water outlet assembly includes a main body 2, which includes a main body 21 and a first water outlet part 22. The main body 2 is provided with a first water outlet channel 24; the main body 21 is provided with a first valve chamber 25 and an air storage chamber 23, the first water outlet part 22 is provided with a first water outlet 221, and the first water outlet channel 24 runs through the main body 21 and the first water outlet part 22 and is connected to the first water outlet 221; the first valve chamber 25 is used to install a first switching mechanism 4 to control the water circuit. The first water outlet channel 24 is connected to the water outlet end of the first valve chamber 25, and the air storage chamber 23 is located between the water outlet end of the first valve chamber 25 and the first water outlet 221. The air storage chamber 23 is provided with a first through hole 231 facing the direction of the water flow, and the first through hole 231 connects the air storage chamber 23 and the first water outlet channel 24; therefore, when the water outlet assembly is used for the first time, water flows into the first water outlet channel 24 from the water outlet end of the first valve chamber 25, and the gas in the first water outlet channel 24 is driven by the water flow, a part of which is discharged from the first water outlet 221, and a part of which enters the air storage chamber 23 from the first through hole 231. When the water flows through the first through hole 231, a part of the water flows into the air storage chamber 23 and mixes with the gas in the air storage chamber 23. When the pressure of the water-gas mixture in the air storage chamber 23 and the water flow in the first water outlet channel 24 reaches equilibrium, the water flow no longer flows into the air storage chamber 23, but directly flows out from the first water outlet 221. Since the gas storage chamber 23 accommodates a portion of the gas discharged from the first water outlet channel 24, the amount of gas discharged through the first water outlet 221 is reduced, thereby reducing the disturbance of the water column caused by the gas discharge in the water outlet channel. Compared with the prior art, the present invention adopts a structure in which the gas storage chamber 23 is arranged in the body 2, which improves the user experience.

[0081] In this embodiment, the first through hole 231 faces the direction of water flow, which is more conducive to the water flow driving the gas in the first water outlet channel 24 to enter the gas storage cavity 23 and flow into the gas storage cavity 23 to mix with the gas.

[0082] In this embodiment, the first water outlet 221 is arranged upward and the water outlet direction is 70-78° to the horizontal direction, preferably 74°, which effectively ensures the integrity of the shape of the water column under different water pressures and improves the mouthwash experience.

[0083] In this embodiment, the first water outlet channel 24 is divided into an A channel 241 connected to the first water outlet 221 and a B channel 242 connected to the air storage chamber 23 and the first valve chamber 25 by setting a water outlet chamber 26, and the flow cross-sectional area of ​​the water outlet chamber 26 is larger than the cross-sectional area of ​​the A and B channels 242, which has the effect of further decelerating and converging the water flow flowing into the B channel 242, and has a certain acceleration on the water flow flowing into the A channel 241, which is beneficial to maintaining the stability of the water column when the water flows out of the first water outlet 221.

[0084] In this embodiment, four bends are provided in the B channel 242 to increase the flow resistance of the water along the first water outlet channel 24, so that the gas in the water channel is fully mixed with the water flow, which not only reduces the flow rate of the water reaching the water outlet chamber 26, but also reduces the content of the gas existing alone, thereby making the outlet water column softer and providing a better experience.

[0085] In this embodiment, the water outlet chamber 26 includes a first chamber 261 and a second chamber 262. The second chamber 262 is connected to the first chamber 261 via two opposite second through holes 263, so that water flows from the B channel 242 into the second chamber 262, and then is divided into two or more flow channels through the second through holes 263 and then enters the first chamber 261, and the water flow becomes smoother.

[0086] In this embodiment, a flow restrictor is placed in the second chamber 262 to limit the flow when the water flow is relatively large, so as to achieve the effect of stabilizing the water column.

[0087] In this embodiment, the first plug post 2224 is plugged into the inner wall of the grille 2612 to divide the first cavity 261 into an inner cavity and an outer cavity that are interconnected. The outer cavity surrounds the inner cavity, the inner cavity is connected to the A channel 241, and the outer cavity is connected to the second through hole 263; therefore, water flows into the outer cavity from the second through hole 263, flows through the grille 2612 into the inner cavity, and enters the A channel 241 to flow out from the first water outlet 221. The grille 2612 has a rectifying effect on the water flowing through. Since the cross-section of the inner cavity is smaller than that of the outer cavity, the inner cavity formed by the first plug post 2224 and the grille 2612 has a convergence effect on the incoming water flow, forming concentrated water upwelling into the A channel 241, so that the flow rate of water increases when entering the A channel 241, and the integrity of the water column out of the first water outlet 221 can be maintained when the water pressure is low.

[0088] In this embodiment, the second plug post 2622 extends toward the B channel 242 , and plays a role in decelerating and buffering the water flow flowing from the B channel 242 into the second chamber 262 .

[0089] In this embodiment, a filter screen is provided in the inner cavity to rectify the water flow and filter out impurities in the water, so that the water column out of the first water outlet 221 is healthier and clearer.

[0090] In this embodiment, the button 41 is used to switch the mechanism to switch the water passage 211 to connect to the first water outlet channel 24 or the second water outlet channel 212. The structure is relatively simple and easy to operate.

[0091] In this embodiment, the body 2 is rotatably connected to the second switching mechanism 5, and controls the second switching mechanism 5 to switch the water inlet to connect to the water channel 211 or the third water outlet channel 213, so that the water outlet component integrates multifunctional water outlet and has a compact structure.
