[0079] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0080] like Figures 1 to 4 As shown, the utility model provides a water outlet, which includes a shell 1, the shell 1 has a first flow channel 2 and a second flow channel 3 which are independent of each other, the first flow channel 2 is used to output drinking water, and the second flow channel 3 is used to output domestic water; a first water outlet 101, the first water outlet 101 is located at the water outlet end of the shell 1, and a part of the first flow channel 2 is formed inside the first water outlet 101; a second water outlet 102, the second water outlet 102 is located at the water outlet end of the shell 1, the second water outlet 102 is arranged around the outer periphery of the first water outlet 101, and a part of the second flow channel 3 is formed between the second water outlet 102 and the first water outlet 101; a jet part 4, the jet part 4 is arranged between the first water outlet 101 and the second water outlet 102, and the jet part 4 has at least one water outlet hole 401 which is connected to the second flow channel 3, and the water outlet hole 401 is used to make the domestic water flowing through the second flow channel 3 be output in a jet manner.

[0081] In the utility model, a shell 1 of the water outlet is provided with a first flow channel 2 and a second flow channel 3 which are independent of each other, and a first water outlet portion 101 and a second water outlet portion 102 are provided at the water outlet end of the shell 1, wherein the second water outlet portion 102 is arranged around the outer periphery of the first water outlet portion 101, so that a part of the first flow channel 2 is formed inside the first water outlet portion 101, and a part of the second flow channel 3 is formed between the first water outlet portion 101 and the second water outlet portion 102. In actual use, drinking water can be output through the first flow channel 2 and domestic water can be output through the second flow channel 3 according to different needs of users, thereby achieving the purpose of a water outlet being able to output different water qualities and meeting the water needs of different scenarios. For example, if the user needs to output drinking water, the second flow channel 3 will not output water, and only drinking water will be output through the first flow channel 2; if the user needs domestic water (such as ozone water) to wash fruits and vegetables, the first flow channel 2 will not output water, and only domestic water will be output through the second flow channel 3, thereby improving the user experience.

[0082] In the utility model, since the second water outlet 102 is arranged on the outer periphery of the first water outlet 101, and a jet part 4 is arranged between the first water outlet 101 and the second water outlet 102, the jet part 4 has a water outlet hole 401 connected with the second flow channel 3, domestic water can be output in a jet manner through the water outlet hole 401 on the jet part 4, so that the domestic water ejected from the water outlet hole 401 will not contact the first water outlet 101, and no domestic water will remain on the first water outlet 101. Therefore, when outputting drinking water, the water quality of the drinking water will not be contaminated by the domestic water remaining on the first water outlet 101, and the user's water safety is guaranteed while meeting the user's water demand.

[0083] In an optional embodiment of the present invention, the flow area of ​​the water outlet 401 located on the jet portion 4 is 0.2 mm 2 -3mm 2 After domestic water flows in and fills the second flow channel 3 formed between the first water outlet 101 and the second water outlet 102, the flow area of ​​the water outlet 401 is set so that the water output through the water outlet 401 can present a jet effect to achieve the purpose of jet flushing, which can not only achieve a good cleaning effect on fruits and vegetables, but also prevent water droplets from splashing after the jet is formed, thereby preventing the output domestic water from splashing and remaining on the first water outlet 101, and will not pollute the output drinking water. Among them, the flow area of ​​the water outlet 401 is the cross-sectional area of ​​the water outlet 401.

[0084] Further, such as Figure 3 As shown, the water outlet hole 401 on the jet part 4 is a circular hole, and the aperture of the water outlet hole 401 is 0.5mm-2mm, so that domestic water can be output in the form of a jet.

[0085] Further, such as Figure 3 As shown, there are multiple water outlet holes 401 located on the jet portion 4, and the multiple water outlet holes 401 are evenly and spaced apart with the same center of a circle, so that the multiple water outlet holes 401 cooperate to form multiple rings arranged inside and outside, wherein the spacing between two adjacent water outlet holes is greater than or equal to 1 mm, so that domestic water can not only be output in a jet manner through the water outlet holes 401, but also the domestic water output by two adjacent water outlet holes 401 will not interfere with each other, thereby ensuring the jet effect.

[0086] In an optional embodiment of the present invention, Figure 2 , Figure 3 As shown, the first water outlet 101 and the second water outlet 102 are coaxial sleeve structures, and the central axis of the water outlet hole 401 located on the jet part 4 is parallel to the central axis of the first water outlet 101, thereby ensuring that domestic water and pure water are output in the same direction and avoiding mutual influence when outputting domestic water and pure water.

[0087] In another optional embodiment of the utility model, along the water outlet direction of the water outlet 401, the central axis of the water outlet 401 is tilted away from the central axis of the first water outlet portion 101, so that the water ejected from the water outlet 401 is tilted away from the first water outlet portion 101, thereby avoiding the output of domestic water affecting the output of pure water.

[0088] In a specific embodiment of the present invention, Figures 1 to 3 As shown, at least part of the shell 1 is cylindrical, and the first water outlet 101 is a central tube penetrating the shell 1. The central tube is coaxially arranged with the shell 1, and a part of the first flow channel 2 is formed in the central tube, and a part of the second flow channel 3 is formed between the outer wall of the central tube and the inner wall of the shell 1. Among them, the jet part 4 is annular, and the jet part 4 is detachably arranged between the shell 1 and the central tube. The annular outer edge of the jet part 4 is sealed and connected to the inner wall of the shell 1, and the annular inner edge of the jet part 4 is sealed and connected to the outer wall of the central tube. Among them, a first sealing ring 5 can be arranged between the annular outer edge of the jet part 4 and the inner wall of the shell 1, and the first sealing ring 5 is sealed and pressed between the annular outer edge of the jet part 4 and the inner wall of the shell 1, and a second sealing ring 6 is arranged between the annular inner edge of the jet part 4 and the outer wall of the central tube, and the second sealing ring 6 is sealed and pressed between the annular inner edge of the jet part 4 and the outer wall of the central tube, so as to ensure good sealing between the jet part 4 and the central tube and the shell 1, and avoid water leakage at the connection position. Of course, the jet portion 4 may also be formed integrally with the central tube and the shell 1 .

[0089] Specifically, Figure 4As shown, when the jet portion 4 is detachably connected to the shell 1, a plurality of protrusions 402 may be arranged on the outer wall of the jet portion 4 at intervals along its circumference, and a plurality of snap-fitting portions (snap-fitting holes 1021 or snap-fitting grooves) may be arranged on the second water outlet portion 102 of the shell 1 along its circumference. The plurality of snap-fitting portions cooperate with the plurality of protrusions 402 and correspond one to one. The plurality of protrusions 402 may be snap-fitted with the corresponding snap-fitting portions, respectively, thereby realizing the detachable assembly of the jet portion 4, facilitating the inspection and replacement of the jet portion 4, and ensuring long-term and stable water discharge from the water outlet.

[0090] In an optional embodiment of the present invention, Figure 1 , Figure 2 As shown, the water outlet end of the central tube protrudes from the jet part 4, so as to avoid the influence of the domestic water ejected from the water outlet hole 401 of the jet part 4 on the output pure water. It is preferred that the plane where the water outlet end of the central tube is located (i.e., the first plane 1011 where the pure water and the water outlet end of the central tube are separated when outputting pure water) protrudes from the end face of the water outlet side of the jet part 4 (i.e., the second plane 403 where the domestic water and the jet part 4 are separated when outputting domestic water) by 1-10mm. Within this range, the domestic water ejected from the water outlet hole 401 will not adhere to the central tube or the water outlet end of the central tube when the pressure in the second flow channel 3 is low due to the water outlet end of the central tube protruding from the jet part 4 too long, nor will the ejected domestic water splash to the water outlet end of the central tube due to the water outlet end of the central tube protruding from the jet part 4 too short, causing the pure water to be contaminated by the domestic water.

[0091] In the utility model, the shell 1 has independent first flow channel 2 and second flow channel 3. Since the shell 1 of the water outlet extends in different directions at different positions, the water outlet end of the shell 1 can generally extend in the vertical direction. Of course, it can also have a certain angle with the vertical direction (that is, an inclined setting).

[0092] In a specific embodiment of the present invention, Figures 1 to 4As shown, the first flow channel 2 includes a first section first flow channel 201 and a second section first flow channel 202 that are connected, the second section first flow channel 202 is formed inside the first water outlet 101, and the first section first flow channel 201 and the second section first flow channel 202 are not parallel or not located in a straight line. Specifically, the second section first flow channel 202 can extend generally in the vertical direction, and the first section first flow channel 201 can extend generally in the horizontal direction, so that there is a corner at the connection between the first section first flow channel 201 and the second section first flow channel 202; the second flow channel 3 includes a first section second flow channel 301 and a second section second flow channel 302 that are connected, the second section second flow channel 302 is formed between the first water outlet 101 and the second water outlet 102, and the first section second flow channel 301 and the second section second flow channel 302 are not parallel or not located in a straight line. Specifically, the second section second flow channel 302 may be annular and extend generally in the vertical direction, and the first section second flow channel 301 may extend generally in the horizontal direction, so that there is a corner at the connection between the first section second flow channel 301 and the second section second flow channel 302. By setting the first section first flow channel 201 in the first flow channel 2 and the first section second flow channel 301 in the second flow channel 3, it is convenient for the first flow channel 2 and the second flow channel 3 to be connected to the upstream water pipe.

[0093] Since there is a corner at the connection between the first section second flow channel 301 and the second section second flow channel 302, when domestic water just enters the second section second flow channel 302 from the first section second flow channel 301, there will be a large rotation inertia, resulting in the water flow in the second section second flow channel 302 cannot be smoothly output. In a specific embodiment of the utility model, Figure 2 , Figure 4 As shown, in the utility model, along the flow direction of domestic water, a rectifying member 7 is arranged in the second section second flow channel 302 and upstream of the jet portion 4, the rectifying member 7 is annular, the rectifying member 7 is located between the outer wall of the central tube and the inner wall of the shell 1, and the annular inner edge of the rectifying member 7 is sealed with the outer wall of the central tube, the annular outer edge of the rectifying member 7 is sealed with the inner wall of the shell 1, and a plurality of flow holes 701 are spaced and evenly arranged along the circumference of the rectifying member 7. When the rotating domestic water flows to the position of the rectifying component 7, the rectifying component 7 will have a certain rectifying effect on the rotating flow direction and turbulent flow of the domestic water. The domestic water flows downward from the multiple flow holes 701, so that the domestic water entering the second section second flow channel 302 can be output smoothly, thereby forming a stable water flow with a low degree of water-gas mixing to flow to the jet part 4. Since the rectifying component 7 has a stabilizing effect on the output of the domestic water, it prevents the output domestic water from deviating from a certain direction or angle, thereby ensuring the output water type of the domestic water, and further ensuring that the domestic water can be output in a stable jet manner.

[0094] Further, such as Figure 2 , Figure 4 As shown, along the flow direction of domestic water, in the second section second flow channel 302, a filter screen 8 is arranged upstream of the jet part 4 and downstream of the rectifying part 7. The filter screen 8 is annular, and the filter screen 8 is located between the outer wall of the central tube and the inner wall of the shell 1, and the annular inner edge of the filter screen 8 is sealed with the outer wall of the central tube, and the annular outer edge of the filter screen 8 is sealed with the inner wall of the shell 1. The filter screen 8 further plays a stabilizing role in the output of domestic water, ensuring that the domestic water is output in a stable jet manner. Among them, the filter screen 8 can be but not limited to an 80-mesh filter screen, which can not only play a stabilizing role in the output of domestic water, but also when there is no need to output domestic water, the filter screen 8 can play a water locking role to prevent the remaining part of the domestic water in the second water outlet 102 from dripping.

[0095] Since there is a corner at the connection point between the first section first flow channel 201 and the second section first flow channel 202, when drinking water just enters the second section first flow channel 202 from the first section first flow channel 201, there will be a large rotation inertia, resulting in the water flow in the second section first flow channel 202 cannot be smoothly output. In a specific embodiment of the present utility model, Figure 2 As shown, a plurality of rectifying ribs 9 are evenly arranged in the first water outlet portion 101, and the rectifying ribs 9 extend along the extension direction of the portion of the first flow channel 2 corresponding to the first water outlet portion 101, and the plurality of rectifying ribs 9 are spaced and evenly arranged along the circumferential direction of the portion of the first flow channel 2 corresponding to the first water outlet portion 101, which can play a certain rectifying role on the rotating flow direction and turbulent flow of drinking water, thereby ensuring the smooth output of drinking water.

[0096] In an optional embodiment of the present invention, the drinking water includes pure water; and / or the domestic water includes ozone water.

[0097] The characteristics and advantages of the water outlet of the utility model are:

[0098] 1. The water outlet can output water of different quality to meet the water demand in different scenarios. For example, if the user needs to output drinking water, the second flow channel 3 will not output water, and only drinking water will be output through the first flow channel 2; if the user needs domestic water (such as ozone water) to wash fruits and vegetables, the first flow channel 2 will not output water, and only domestic water will be output through the second flow channel 3, thereby improving the user experience.

[0099] Second, in the water outlet, the jet part 4 is arranged so that domestic water can be discharged in a jet manner. The domestic water discharged in this way will not come into contact with the first water outlet part 101, and no domestic water will remain on the first water outlet part 101. Therefore, when drinking water is discharged, the water quality of the drinking water will not be contaminated by the domestic water remaining on the first water outlet part 101, thereby ensuring the user's water safety while meeting the user's water demand.

[0100] like Figures 5 to 7 As shown, the utility model provides a water outlet device, which includes a shell 10 and the above-mentioned water outlet nozzle 20, and the water outlet nozzle 20 is arranged at the water outlet end of the shell 10; wherein, an independent first water pipe 30 and a second water pipe 40 are arranged in the shell 10, the first water pipe 30 is connected to the first flow channel 2 of the water outlet nozzle 20, and drinking water is transported to the first flow channel 2 of the water outlet nozzle 20 through the first water pipe 30; the second water pipe 40 is connected to the second flow channel 3 of the water outlet nozzle 20, and domestic water is transported to the second flow channel 3 of the water outlet nozzle 20 through the second water pipe 40.

[0101] Further, such as Figures 5 to 7 As shown, the housing 10 includes a base portion 1001 and an extension portion 1002, the water outlet 20 is arranged at the end of the extension portion 1002, and the first water pipe 30 and the second water pipe 40 are both arranged in the base portion 1001 and the extension portion 1002.
