Description

TECHNICAL FIELD

[0001] The utility model relates to water purification technical field, especially a kind of water outlet nozzle and water purifier. BACKGROUND

[0002] With the gradual popularization of water purifier in modern society and the iterative development of water purifier itself, most of the high-end water purifiers in the current market are equipped with sterilization device. However, due to the limitation of the structure characteristics of the sterilization device itself, the sterilization device in the prior art is arranged at a position which is a certain distance away from the discharge port relative to the end of the fluid flow path. In the foregoing case, the fluid after sterilization by the sterilization device can still breed bacteria during the process of passing to the discharge port, resulting in that there are still many bacteria in the discharged fluid, and the total number of bacteria exceeds the standard and is not conducive to the safety of drinking.

[0003] Most of the water outlet nozzles in the current market lack flow stabilization for the fluid leaving the discharge port. In the absence of flow stabilization capability, the fluid leaving the discharge port may drip on one hand, and may also splash on the other hand.

[0004] Therefore, there is a demand in the market for a water outlet nozzle and water purifier which can reduce the bacteria breeding in the fluid after sterilization and has flow stabilization capability. SUMMARY

[0005] The technical problem to be solved by the utility model is to realize the flow stabilization of fluid, and provide a water outlet nozzle and water purifier.

[0006] The utility model solves the above technical problem by the following technical scheme:

[0007] A water outlet nozzle is used for a water purifier, and the water outlet nozzle is arranged at a discharge port at the end of a fluid flow path. The water outlet nozzle comprises:

[0008] A main channel is arranged between the inlet and the outlet of the water outlet nozzle.

[0009] Wherein, along the flow direction of the fluid in the main channel, the radial side of the main channel is sequentially provided with a first opening and a second opening, and a flow stabilization loop located outside the main channel is communicated between the first opening and the second opening.

[0010] Wherein, along the flow direction of the fluid, the inlet, the first opening, the flow stabilization loop, the second opening and the outlet are sequentially communicated.

[0011] In the present scheme, the radial side of the main channel is sequentially provided with the first opening and the second opening, and the flow stabilization loop located outside the main channel is communicated between the first opening and the second opening. In other words, when the fluid flows through the main channel, the first opening becomes the inlet of the flow stabilization loop, and the second opening becomes the outlet of the flow stabilization loop.

[0012] In the foregoing arrangement, the flow path of the fluid in the water outlet nozzle is arranged in sequence from the inlet, the first opening, the flow stabilizing circuit, the second opening and the outlet. Thus, the flow path in the present scheme is longer than the conventional communication mode of directly communicating from the inlet of the water outlet nozzle to the outlet of the water outlet nozzle, and the fluid can utilize the longer flow path to slow down sufficiently, realizing the flow stabilizing effect on the fluid.

[0013] Preferably, the middle section of the main channel is provided with a partition plate, which divides the main channel into an inlet channel and a discharge channel;

[0014] The first opening is located at one end of the inlet channel towards the partition plate, and the second opening is located at one end of the discharge channel towards the partition plate; and / or, a plurality of first openings are distributed circumferentially in the inlet channel, and a plurality of second openings are distributed circumferentially in the discharge channel.

[0015] In the present scheme, the main channel is divided into two sections by the partition plate, one section connected to the inlet of the water outlet nozzle is the inlet channel, and the other section connected to the outlet of the water outlet nozzle is the discharge channel. On the one hand, the partition plate can prevent the fluid from flowing directly from the inlet of the water outlet nozzle to the outlet of the water outlet nozzle; on the other hand, after the fluid enters the main channel from the inlet of the water outlet nozzle, it will impact on the partition plate and slow down thereby, constituting a flow stabilizing effect on the fluid. Subsequently, the fluid slowed down by impacting on the partition plate flows into the flow stabilizing circuit from the first opening, and after passing through the flow stabilizing circuit, it flows to the discharge channel from the second opening, and finally is discharged from the outlet of the water outlet nozzle, so that the fluid can further be buffered and slowed down in the flow stabilizing circuit by flowing through the flow stabilizing circuit, further playing a flow stabilizing effect.

[0016] Further, the first opening is located at one end of the inlet channel towards the partition plate, so that after the fluid is slowed down by impacting on the partition plate, it can flow to the flow stabilizing circuit from the first opening, saving the process of guiding the fluid in the inlet channel to the first opening, avoiding the turbulence that the fluid itself may generate in the foregoing process, and further optimizing the flow stabilizing effect.

[0017] In addition, the second opening is located at one end of the discharge channel towards the partition plate, so that after the fluid enters the discharge channel from the second opening, it is naturally guided by gravity to flow to the outlet of the water outlet nozzle, thereby avoiding the turbulence that the fluid may generate by flowing towards the partition plate against gravity after entering the discharge channel from the second opening, and further optimizing the flow stabilizing effect.

[0018] On the other hand, multiple first openings are circumferentially spaced in the inlet channel, and multiple second openings are circumferentially spaced in the outlet channel, so that the fluid can enter the steady flow loop uniformly from the first opening and flow out of the steady flow loop uniformly from the second opening, avoiding turbulence that may be caused by uneven fluid distribution.

[0019] Preferably, the current stabilizing circuit is an annular chamber surrounding the radial side of the main channel. A guide pipe is provided in the current stabilizing circuit, which divides the current stabilizing circuit into a first circuit chamber and a second circuit chamber. The first circuit chamber is spaced between the main channel and the second circuit chamber.

[0020] The guide pipe has a first connecting port at the inlet end facing the outlet nozzle and a second connecting port at the outlet end facing the outlet nozzle. The first and second connecting ports connect the second circuit chamber and the first circuit chamber.

[0021] In this design, the guide pipe divides the annular flow stabilization loop into a first loop chamber and a second loop chamber. A first connecting port is provided at the end of the guide pipe facing the inlet of the water outlet, and a second connecting port is provided at the end of the guide pipe facing the outlet of the water outlet. This allows the fluid to enter the first loop chamber from the first opening, where it is initially buffered, and then flows further into the second loop chamber from the first and second connecting ports, where it is buffered a second time. This further optimizes the flow stabilization effect.

[0022] Preferably, a sealing ring is provided in the first circuit chamber. The sealing ring is located at the position separated by the first opening and the second opening on the main channel, and the sealing ring is sealed against the inner surface of the guide tube and the outer surface of the main channel.

[0023] Along the direction of fluid flow, the inlet, the first opening, the first connecting port, the second connecting port, the second opening, and the outlet are connected in sequence.

[0024] In this design, the sealing ring is positioned on the main channel at the location separated by the first opening and the second opening. The sealing ring is tightly abutted against the inner surface of the guide tube and the outer surface of the main channel. As a result, the fluid entering the first loop chamber from the first opening is forced to the first connecting port. The fluid entering the second loop chamber from the first connecting port flows along the length of the second loop chamber, then returns to the first loop chamber from the second connecting port, and then enters the discharge channel through the second opening connected to the first loop chamber. That is, the fluid flows sequentially through the inlet, the first opening, the first connecting port, the second connecting port, the second opening, and the outlet. In this way, the fluid itself travels a long path, which helps the fluid itself to use the long path for buffering, thereby further optimizing the flow stabilization effect.

[0025] Preferably, the flow guide pipe is made of Teflon material.

[0026] In this solution, the flow guide pipe is made of Teflon material, which is itself corrosion-resistant, high-temperature-resistant and has a small friction coefficient, ensuring the service life of the flow guide pipe.

[0027] Preferably, the water outlet nozzle further comprises a shell, and the main channel, the flow guide pipe, the first loop chamber and the second loop chamber are all located inside the shell.

[0028] In this solution, the shell protects the main channel, the flow guide pipe, the first loop chamber and the second loop chamber located inside the shell, and also prevents accidental leakage of fluid from the water outlet nozzle.

[0029] Preferably, the outlet of the water outlet nozzle is provided with a flow stabilizing unit through which fluid passes, and the flow stabilizing unit is provided with a guide surface that guides the fluid flowing to the outlet of the water outlet nozzle.

[0030] In this solution, the flow stabilizing unit is provided with a guide surface, which guides the fluid when it flows onto the guide surface, so that the fluid can flow to the outlet of the water outlet nozzle and out of the discharge port in a smooth manner, playing a flow stabilizing role. On the other hand, the flow stabilizing unit also increases the surface tension of the fluid at the outlet of the water outlet nozzle, reducing the risk of dripping.

[0031] Preferably, the flow stabilizing unit comprises a plurality of flow guide ribs, the guide surface is located on the flow guide ribs, the plurality of flow guide ribs are distributed circumferentially with the center of the outlet of the water outlet nozzle as the reference, and the space between adjacent two flow guide ribs communicates the inside of the main channel with the outlet of the water outlet nozzle.

[0032] In this solution, the plurality of flow guide ribs are distributed circumferentially with the center of the outlet of the water outlet nozzle as the reference, and the space between adjacent two flow guide ribs communicates the inside of the main channel with the outlet of the water outlet nozzle, thereby assisting the fluid to flow out of the discharge port uniformly; wherein the respective guide surfaces on the plurality of flow guide ribs can independently guide the fluid, and can also prevent turbulence by the mutual cooperation between the guide surfaces, effectively preventing splashing, and achieving an optimized flow stabilizing effect.

[0033] Preferably, the water outlet nozzle further comprises a sterilization part for sterilizing the water flow in the main channel, and the shell is provided with a containing cavity for containing the sterilization part.

[0034] In this solution, the sterilization part included in the water outlet nozzle is used to achieve the sterilization effect on the fluid and / or the main pipeline. Further, the water outlet nozzle is arranged at the discharge port at the end of the fluid flow path, so that the fluid after sterilization can be directly discharged through the discharge port, thereby avoiding the growth of bacteria in the process of flowing to the discharge port.

[0035] The water purifier further comprises the water outlet nozzle.

[0036] In the present solution, the water purifier achieves the flow stabilizing effect on the fluid by being provided with the water outlet nozzle of any of the above.

[0037] The positive progress effect of the utility model lies in: in the water outlet nozzle of the utility model, the radial side surface of the main channel is sequentially provided with a first opening and a second opening, and the first opening and the second opening are communicated with a flow stabilizing loop located outside the main channel; in other words, when the fluid flows through the main channel, the first opening becomes the inlet of the flow stabilizing loop, and the second opening becomes the outlet of the flow stabilizing loop.

[0038] Under the foregoing setting mode, the flow path adopted by the fluid in the water outlet nozzle is arranged in sequence through the inlet, the first opening, the flow stabilizing loop, the second opening and the outlet. Therefore, compared with the conventional communication mode of directly communicating from the inlet of the water outlet nozzle to the outlet of the water outlet nozzle, the flow path in the present solution is longer, and the fluid can utilize the longer flow path to sufficiently slow down, thereby achieving the flow stabilizing effect on the fluid.

[0066] The utility model will be further illustrated by way of examples below, but the utility model is not limited in the scope of the examples.

[0067] As Figures 1-3 shown, the embodiment provides a water outlet nozzle 1 for a water purifier, the water outlet nozzle 1 is arranged at the discharge port 2 at the end of the fluid flow path, and the water outlet nozzle 1 comprises:

[0068] A main channel 10 is arranged between the inlet 11 and the outlet 12 of the water outlet nozzle 1.

[0069] Wherein, along the flow direction of the fluid in the main channel 10, the radial side of the main channel 10 is sequentially provided with a first opening 31 and a second opening 32, and the first opening 31 and the second opening 32 are communicated with a flow stabilizing loop 40 located outside the main channel 10.

[0070] Wherein, along the flow direction of the fluid, the inlet 11, the first opening 31, the flow stabilizing loop 40, the second opening 32 and the outlet 12 are sequentially communicated.

[0071] In specific implementation, the radial side of the main channel 10 is sequentially provided with the first opening 31 and the second opening 32, and the first opening 31 and the second opening 32 are communicated with the flow stabilizing loop 40 located outside the main channel 10; in other words, when the fluid flows through the main channel 10, the first opening 31 becomes the inlet 11 of the flow stabilizing loop 40, and the second opening 32 becomes the outlet 12 of the flow stabilizing loop 40.

[0072] In the foregoing arrangement, the flow path of the fluid in the water outlet nozzle 1 is arranged in sequence from the inlet 11, the first opening 31, the flow stabilizing circuit 40, the second opening 32 and the outlet 12. Thus, the flow path in the present embodiment is longer than the conventional arrangement of directly connecting from the inlet 11 of the water outlet nozzle 1 to the outlet 12 of the water outlet nozzle 1, and the fluid can be sufficiently slowed down by the longer flow path, thereby achieving the flow stabilizing effect on the fluid.

[0073] In the present embodiment, the flow path constructed by the foregoing arrangement is provided with smooth walls, thereby providing a relatively simple and easy-to-produce structure. However, those skilled in the art can further improve the walls of the flow path, for example, by adding protrusions on the walls, so that the fluid can be slowed down after impacting on the protrusions, thereby further achieving the flow stabilizing effect on the fluid, which is not limited in the present embodiment.

[0074] As shown in Figures 1-3 , the middle section of the main channel 10 is provided with a partition plate 15, which divides the main channel 10 into an inlet channel 21 and an outlet channel 22;

[0075] wherein the first opening 31 is located at one end of the inlet channel 21 facing the partition plate 15, and the second opening 32 is located at one end of the outlet channel 22 facing the partition plate 15; and / or, a plurality of first openings 31 are circumferentially spaced apart in the inlet channel 21, and a plurality of second openings 32 are circumferentially spaced apart in the outlet channel 22.

[0076] In specific implementation, the main channel 10 is divided into two sections by the partition plate 15, one section connected to the inlet 11 of the water outlet nozzle 1 is the inlet channel 21, and the other section connected to the outlet 12 of the water outlet nozzle 1 is the outlet channel 22. On the one hand, the partition plate 15 can prevent the fluid from directly flowing from the inlet 11 of the water outlet nozzle 1 to the outlet 12 of the water outlet nozzle 1. On the other hand, after the fluid enters the main channel 10 from the inlet 11 of the water outlet nozzle 1, it will impact on the partition plate 15 and be slowed down thereby, thereby achieving the flow stabilizing effect on the fluid. Subsequently, the fluid slowed down by impacting on the partition plate 15 flows into the flow stabilizing circuit 40 from the first opening 31, and then flows to the outlet channel 22 from the second opening 32 after passing through the flow stabilizing circuit 40, and finally is discharged from the outlet 12 of the water outlet nozzle 1, so that the fluid can be further buffered and slowed down in the flow stabilizing circuit 40 by flowing through the flow stabilizing circuit 40, thereby further achieving the flow stabilizing effect.

[0077] Furthermore, the first opening 31 is located at the end of the inlet channel 21 facing the baffle 15, so that after the fluid impacts the baffle 15 and is thus decelerated, it can flow from the first opening 31 into the flow stabilization circuit 40. This saves the process of the fluid being guided to the first opening 31 in the inlet channel 21, avoids the turbulence that the fluid itself may generate in the aforementioned process, and further optimizes the flow stabilization effect.

[0078] In addition, the second opening 32 is located at the end of the discharge channel 22 facing the baffle 15, so that after the fluid enters the discharge channel 22 from the second opening 32, it is naturally guided by gravity to flow to the outlet 12 of the water outlet 1. This avoids the turbulence that may be generated when the fluid enters the discharge channel 22 from the second opening 32 and flows against gravity toward the baffle 15, thus further optimizing the flow stabilization effect.

[0079] On the other hand, multiple first openings 31 are circumferentially spaced in the inlet channel 21, and multiple second openings 32 are circumferentially spaced in the outlet channel 22, so that the fluid can enter the flow stabilizing circuit 40 uniformly from the first openings 31 and flow out of the flow stabilizing circuit 40 uniformly from the second openings 32, avoiding turbulence that may be caused by uneven fluid distribution.

[0080] In this embodiment, the baffle 15 has a flat plate structure, thus providing a relatively simple and easy-to-manufacture structure. However, those skilled in the art should be able to conceive of adjusting the structural shape of the baffle 15 itself, such as providing a buffer surface or other flow stabilizing structure commonly found in the art on the baffle 15, which can play a buffering role. This embodiment does not limit this.

[0081] Furthermore, in this embodiment, both the first opening 31 and the second opening 32 are circular holes, thus providing a relatively simple and easy-to-manufacture structure. However, those skilled in the art should be able to conceive of adjusting the openings in this embodiment according to actual needs, such as replacing the circular hole structure with a square hole structure or an elliptical hole structure, etc., and this embodiment does not limit this.

[0082] like Figures 1-3 As shown, the current stabilizing circuit 40 is an annular chamber surrounding the radial side of the main channel 10. A guide pipe 60 is provided in the current stabilizing circuit 40, which divides the current stabilizing circuit 40 into a first circuit chamber 81 and a second circuit chamber 82. The first circuit chamber 81 is spaced between the main channel 10 and the second circuit chamber 82.

[0083] The guide pipe 60 has a first connecting port 71 at one end facing the inlet 11 of the outlet 1, and a second connecting port 72 at one end facing the outlet 12 of the outlet 1. The first connecting port 71 and the second connecting port 72 connect the second circuit chamber 82 and the first circuit chamber 81.

[0084] In practical implementation, the guide pipe 60 divides the annular flow stabilization circuit 40 into a first circuit chamber 81 and a second circuit chamber 82. The end of the guide pipe 60 facing the inlet 11 of the outlet 1 is provided with a first connecting port 71, and the end of the guide pipe 60 facing the outlet 12 of the outlet 1 is provided with a second connecting port 72. This allows the fluid to enter the first circuit chamber 81 from the first opening 31, where it is first buffered, and then flows further into the second circuit chamber 82 from the first connecting port 71 and the second connecting port 72, where it is buffered again, thereby further optimizing the flow stabilization effect.

[0085] like Figures 1-3 As shown, where Figure 3 The internal flow path is schematically shown using dashed lines and arrows. A sealing ring 83 is provided in the first loop chamber 81. The sealing ring 83 is located on the main channel 10 at the position separated by the first opening 31 and the second opening 32, and the sealing ring 83 is sealed against the inner surface of the guide tube 60 and the outer surface of the main channel 10.

[0086] Along the direction of fluid flow, inlet 11, first opening 31, first connecting port 71, second connecting port 72, second opening 32 and outlet 12 are connected in sequence.

[0087] In specific implementation, the sealing ring 83 is set at the position separated by the first opening 31 and the second opening 32 on the main channel 10, and the sealing ring 83 is sealed against the inner surface of the guide tube 60 and the outer surface of the main channel 10. As a result, the fluid entering the first circuit chamber 81 from the first opening 31 is forced to the first connecting port 71. The fluid entering the second circuit chamber 82 from the first connecting port 71 flows along the length of the second circuit chamber 82 and then returns to the first circuit chamber 81 from the second connecting port 72. Then it enters the discharge channel 22 through the second opening 32 connected to the first circuit chamber 81. That is, the fluid flows through the inlet 11, the first opening 31, the first connecting port 71, the second connecting port 72, the second opening 32 and the outlet 12 in sequence. In this way, the fluid itself travels a long path, which helps the fluid itself to use the long path for buffering, thereby further optimizing the flow stabilization effect.

[0088] In the present embodiment, the sealing ring 83 is arranged at a position on the main channel 10 where the partition 15 is also arranged inside the main channel 10, the sealing ring 83 is located at the same level as the partition 15 as much as possible, and the sealing ring 83 and the partition 15 are both spaced between the first opening 31 and the second opening 32. In the foregoing arrangement, the sealing ring 83 does not become a structural obstacle when the first opening 31 or the second opening 32 is arranged, so that the first opening 31 and the second opening 32 can be arranged at a position as close to the partition 15 as possible, so that the fluid directly flows from the first opening 31 to the steady flow circuit 40 in the shortest path after impacting on the partition 15 and being decelerated thereby, further saving the process of the fluid being guided into the first opening 31 in the inlet channel 21, avoiding the turbulence that the fluid itself can generate in the foregoing process, and further optimizing the steady flow effect. At the same time, it also makes the fluid directly guided by gravity to flow to the outlet 12 of the water outlet nozzle 1 after entering the discharge channel 22 from the second opening 32, thereby avoiding the turbulence that the fluid can generate when resisting gravity and flowing towards the partition 15 after entering the discharge channel 22 from the second opening 32, further optimizing the steady flow effect.

[0089] It should be noted that the present embodiment specifically adopts the arrangement of a single flow guide pipe 60, thereby giving a relatively simple and easy-to-produce and install manner. However, those skilled in the art can also conceive to further improve the present embodiment by adopting a manner of layer-by-layer nesting of multiple flow guide pipes 60, thereby further lengthening the fluid path in the steady flow circuit 40 and making it a labyrinth, which is not limited by the present embodiment.

[0090] As shown in Figures 1-3 , the flow guide pipe 60 is made of Teflon material.

[0091] In specific implementation, the flow guide pipe 60 is made of Teflon material, which is itself corrosion-resistant, high-temperature-resistant and has a small friction coefficient, ensuring the service life of the flow guide pipe 60. As an alternative embodiment, those skilled in the art can also conceive to replace the Teflon material with other materials having similar properties, which is not limited by the present embodiment.

[0092] As shown in Figures 1-3 , the water outlet nozzle 1 further includes a housing 100, and the main channel 10, the flow guide pipe 60, the first circuit chamber 81 and the second circuit chamber 82 are all located inside the housing 100.

[0093] In specific implementation, the housing 100 protects the main channel 10, the flow guide pipe 60, the first circuit chamber 81 and the second circuit chamber 82 located inside it, and also prevents accidental leakage of fluid from the water outlet nozzle 1.

[0094] The water outlet nozzle 1 in the embodiment is installed by using the threaded connection between the shell 100 and the discharge port 2. Alternatively, those skilled in the art can also think of other installation methods such as embedding, which are common in the art, to replace the threaded connection in the embodiment, and the embodiment does not limit this.

[0095] As shown in Figures 1-3 , the outlet 12 of the water outlet nozzle 1 is provided with a flow stabilizing unit 90 for fluid to pass through, and the flow stabilizing unit 90 is provided with a guide surface 901 for guiding the fluid flowing to the outlet 12 of the water outlet nozzle 1.

[0096] In specific implementation, the flow stabilizing unit 90 is provided with the guide surface 901, so that the fluid is guided when flowing to the guide surface 901, so that the fluid can flow to the outlet 12 of the water outlet nozzle 1 in a smooth manner and flow out of the discharge port 2, thereby playing a flow stabilizing role. On the other hand, the flow stabilizing unit 90 also increases the surface tension of the fluid at the outlet 12 of the water outlet nozzle 1, thereby reducing the risk of dripping.

[0097] As shown in Figures 1-3 , the flow stabilizing unit 90 includes a plurality of flow guide ribs 91, and the guide surface 901 is located on the flow guide ribs 91. The plurality of flow guide ribs 91 are distributed in a circumferential direction with the center of the outlet 12 of the water outlet nozzle 1 as a reference, and the space between adjacent two flow guide ribs 91 connects the inside of the main channel 10 and the outlet 12 of the water outlet nozzle 1.

[0098] In specific implementation, the plurality of flow guide ribs 91 are distributed in a circumferential direction with the center of the outlet 12 of the water outlet nozzle 1 as a reference, and the space between adjacent two flow guide ribs 91 connects the inside of the main channel 10 and the outlet 12 of the water outlet nozzle 1, thereby assisting the fluid to flow out of the discharge port 2 uniformly; wherein the respective guide surfaces 901 on the plurality of flow guide ribs 91 can independently guide the fluid, and can also prevent turbulence by cooperation between the guide surfaces 901, can effectively prevent splashing, and has an optimized flow stabilizing effect.

[0099] In the embodiment, the flow guide rib 91 has a cuboid shape, and the two sides of the cuboid are the guide surfaces 901, thereby providing a relatively simple arrangement. However, those skilled in the art can also think of further improving the specific shape of the flow guide rib 91 in specific implementation, for example, using a flow guide rib 91 with a shape like a blade, and the embodiment does not limit this.

[0100] As shown in Figures 1-3 , the water outlet nozzle 1 further includes a sterilization part 50 for sterilizing the water flow in the main channel 10, and the shell 100 is provided with a containing cavity 51 for containing the sterilization part 50.

[0101] In the specific implementation, the sterilization part 50 included in the water outlet nozzle 1 is used to realize the sterilization of the fluid and / or the main pipe. Further, the water outlet nozzle 1 is arranged at the discharge port 2 at the end of the fluid flow path, so that the sterilized fluid can be directly discharged through the discharge port 2, thereby avoiding the growth of bacteria in the fluid during the process of flowing to the discharge port 2.

[0102] The sterilization part 50 used in the embodiment is an LED sterilization unit, which realizes the sterilization function by irradiating the steady current loop 40 with light. It should be noted that in the case of using the LED sterilization unit, those skilled in the art can think of using an isolation structure with airtight function and capable of projecting light between the LED sterilization unit and the steady current loop 40, such as a light-transmitting plate, etc., so as to ensure that the LED sterilization unit will not be short-circuited due to the leakage of the fluid. As an alternative embodiment, those skilled in the art can also use other common sterilization devices in the art to replace the LED sterilization unit according to actual needs, such as silver contact type sterilization devices or ultraviolet sterilization devices, etc. When replacing the sterilization device, those skilled in the art can think of making adaptive adjustments to the specific structure of the water outlet nozzle 1, which is not limited in the embodiment.

[0103] The embodiment also provides a water purifier (not shown in the figure), which also includes the above-mentioned water outlet nozzle 1.

[0104] In the scheme, the water purifier is provided with the above-mentioned water outlet nozzle 1, which realizes the steady flow of the fluid.

[0105] Although the specific embodiments of the present application are described above, those skilled in the art should understand that this is only an example, and the protection scope of the present application is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present application, and these changes and modifications all fall within the protection scope of the present application.
