[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 from the discharge port relative to the end of the fluid flow path. In the foregoing case, the fluid sterilized 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.

[0045] The utility model will be further explained by the mode of embodiment below, but will not therefore limit the utility model in the embodiment range.

[0046] As Figures 1-3 Shown, the utility model provides a water outlet nozzle 1, and the water outlet nozzle 1 is arranged at the discharge port 2 at the fluid flow path end, and the water outlet nozzle 1 includes:

[0047] Main channel 10, and the main channel 10 is arranged and is communicated between the inlet and the outlet of water outlet nozzle 1;

[0048] Sterilization part 50, and the sterilization part 50 is arranged at the outside of main channel 10 and acts on main channel 10, and the sterilization part 50 is sterilized to the water flow in main channel 10 through heating.

[0049] In specific implementation, the sterilization part 50 is arranged outside the main channel 10 and acts on the main channel 10, the sterilization part 50 uses the temperature raised by heating to heat the main channel 10 itself and / or the fluid flowing through the main channel 10, the sterilization method is convenient and the sterilization effect is good. Further, the water outlet nozzle 1 is arranged at the discharge port 2 at the end of the fluid flow path, so that the fluid sterilized can be directly discharged through the discharge port 2, thereby avoiding the growth of bacteria in the process of flowing to the discharge port 2. Therefore, the water outlet nozzle 1 in the scheme has simple and compact structure, and occupies small physical space, so that the application scene is more extensive.

[0050] In the embodiment, the main channel 10 directly communicates with the inlet and outlet of the water outlet nozzle 1, thereby providing a relatively simple arrangement. However, those skilled in the art can conceive that other auxiliary structures commonly used in the art, such as a one-way valve, can be arranged at the connection position of the main channel 10 and the inlet of the water outlet nozzle 1 or the connection position of the main channel 10 and the outlet of the water outlet nozzle 1 according to actual needs, so that the water outlet nozzle 1 can be specialized for specific application scenarios, and the embodiment does not limit this.

[0051] As shown in Figures 1-3 , the sterilization part 50 is arranged in close contact with the outer surface of the main channel 10.

[0052] In specific implementation, the sterilization part 50 is arranged in close contact with the outer surface of the main channel 10, so that when the sterilization part 50 is heated, for example, the sterilization part 50 is powered on by a power source to cause an electrothermal effect, the temperature raised on the sterilization part 50 is directly transmitted to the outer surface of the main channel 10 through heat conduction, and the temperature raised on the outer surface of the main channel 10 is further transmitted to the inner surface of the main channel 10 through heat conduction, thereby realizing sterilization of the inner surface of the main channel 10 and / or the fluid flowing through the inside of the main channel 10, and optimizing the sterilization process.

[0053] In the embodiment, the inner surface of the sterilization part 50 and the outer surface of the main channel 10 are both smooth curved surfaces, so that the inner surface of the sterilization part 50 and the outer surface of the main channel 10 fit each other. However, those skilled in the art can also conceive that the surfaces of the sterilization part 50 and the main channel 10 in contact with each other can be adjusted in shape, for example, to make them interlock, thereby further increasing the contact area therebetween and optimizing the effect of heat conduction, and the embodiment does not limit this.

[0054] As shown in Figures 1-3 , the sterilization part 50 extends from the inlet of the main channel 10 to the outlet of the main channel 10 and is arranged around the radial outside of the main channel 10.

[0055] In the embodiment, the sterilization part 50 extends from the inlet of the main channel 10 to the outlet of the main channel 10 and is arranged radially outside the main channel 10, so that the high temperature of the sterilization part 50 can be transmitted to the inner surface of the entire main channel 10, ensuring that the inner surface of the entire main channel 10 and / or the fluid flowing through the main channel 10 can be sterilized by high temperature all the way, further ensuring sufficient sterilization effect.

[0056] In the embodiment, the length of the single sterilization part 50 is substantially equal to the length of the main channel 10, and the sterilization part 50 is arranged radially outside the main channel 10, so as to provide a relatively simple arrangement. However, those skilled in the art can also conceive, in the embodiment, that the single sterilization part 50 is replaced by multiple sterilization parts 50, so as to allow the multiple sterilization parts 50 to provide progressive heating in the extension direction of the main channel 10, which is not limited in the embodiment.

[0057] As shown in Figures 1-3 , the heating temperature of the sterilization part 50 is not lower than 80℃ and not higher than 90℃.

[0058] In the embodiment, when the heating temperature of the sterilization part 50 is not lower than 80℃ and not higher than 90℃, the sterilization effect can be considered and the service life of the main channel 10 is not affected.

[0059] As shown in Figures 1-3 , the main channel 10 is made of 304 stainless steel.

[0060] In the embodiment, the main channel 10 is made of 304 stainless steel, and the main channel 10 made of the foregoing material has good heat transfer performance and high temperature resistance. The good heat transfer performance ensures that the main channel 10 can be raised to a high enough temperature to ensure its sterilization effect, and the good high temperature resistance ensures that the main channel 10 is not easily damaged by heat, thereby ensuring its service life.

[0061] As an alternative embodiment, those skilled in the art can also conceive that other materials with good heat transfer performance and high temperature resistance are used to replace the 304 stainless steel in the embodiment, such as titanium metal, which is not limited in the embodiment.

[0062] As shown in Figures 1-3 , the outlet of the water outlet nozzle 1 is provided with a flow stabilizing unit 90 for fluid, and the flow stabilizing unit 90 is provided with a guide surface 901 for guiding the fluid flowing out of the outlet of the water outlet nozzle 1.

[0063] In a specific implementation, the flow stabilizing unit 90 is provided with a guide surface 901, so that when the fluid flows onto the guide surface 901, the fluid is guided in a way that the fluid can flow to the outlet 12 of the outlet nozzle 1 and flow out of the discharge port 2 in a smooth manner, thereby playing a role of stabilizing the flow. On the other hand, the flow stabilizing unit 90 also increases the surface tension of the fluid at the outlet 12 of the outlet nozzle 1, thereby reducing the risk of dripping.

[0064] 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 of the outlet nozzle 1 as a reference. The space between the adjacent two flow guide ribs 91 connects the inside of the main channel 10 and the outlet of the outlet nozzle 1.

[0065] In a specific implementation, the plurality of flow guide ribs 91 are distributed in a circumferential direction with the center of the outlet of the outlet nozzle 1 as a reference. The space between the adjacent two flow guide ribs 91 connects the inside of the main channel 10 and the outlet of the outlet nozzle 1, thereby assisting the fluid to flow out of the discharge port 2 uniformly. The respective guide surfaces 901 of the plurality of flow guide ribs 91 can independently guide the fluid, and can also prevent turbulence by cooperating with each other through the guide surfaces 901, thereby effectively preventing splashing and playing an optimized flow stabilizing effect.

[0066] In the present embodiment, the flow guide ribs 91 are in the shape of a cuboid, and the two sides of the cuboid are the guide surfaces 901, thereby providing a relatively simple arrangement. However, in a specific implementation, those skilled in the art can also think of further improving the specific shape of the flow guide ribs 91, such as using flow guide ribs 91 in the shape of blades, and the present embodiment does not limit this.

[0067] Further, the flow guide ribs 91 in the present embodiment can also play a role of providing additional cooling for the fluid flowing out of the discharge port 2. Specifically, by providing a plurality of flow guide ribs 91 and guide surfaces 901 on the flow guide ribs 91, the contact area of the fluid flowing through the flow guide ribs 91 after being sterilized by high temperature is increased by the guide surfaces 901, thereby being able to more fully conduct heat with the air and be cooled.

[0068] As shown in Figures 1-3 , the outlet nozzle 1 can be converted between a normal state and a sterilization state; wherein,

[0069] When the outlet nozzle 1 is in the normal state, the sterilization part 50 is in a non-working state;

[0070] When the outlet nozzle 1 is in the sterilization state, the sterilization part 50 is in a working state to be heated.

[0071] In practical implementation, the water outlet 1 can switch between normal state and sterilization state, so that the sterilization unit 50 can be activated for sterilization when needed, that is, the sterilization unit 50 can be activated for heating, thereby optimizing the working process of the sterilization unit 50.

[0072] More specifically, in this embodiment, the sterilization unit 50 can be switched between a normal state and a sterilization state by the control system. When the control system detects that the water outlet 1 has been used for more than 30 minutes since its last use, the control system will control the sterilization unit 50 to enter the working state for heating and sterilization; when the control system detects that the sterilization unit 50 has been heating continuously for more than 15 minutes, the control system will control the sterilization unit 50 to enter the non-working state, and so on.

[0073] like Figures 1-3 As shown, the water outlet 1 includes a housing 100, a main channel 10, and a sterilization section 50 located inside the housing 100.

[0074] In practice, the outer casing 100 protects the main channel 10 and the sterilization section 50 located inside it, and also prevents fluid from accidentally leaking from the water outlet 1.

[0075] In this embodiment, the water outlet 1 is installed using a threaded connection between the outer casing 100 and the discharge port 2. As an alternative implementation, those skilled in the art should also be able to conceive of using common installation methods in the art, such as fitting, to replace the threaded connection in this embodiment, and this embodiment does not limit this to such methods.

[0076] A water purifier, which further includes the aforementioned water outlet 1.

[0077] In practical implementation, the water purifier reduces the bacteria that proliferate in the sterilized fluid by setting the aforementioned water outlet 1.
