[0002] At present, a water purifier is usually equipped with a dual-temperature faucet for supplying cold water and hot water. Generally, the existing dual-temperature faucet has only one water outlet pipeline. When in use, the control valve is used to control the cold water to be sent from the cold water pipeline to the water outlet pipeline, or the control valve is used to control the hot water to be sent from the hot water pipeline to the water outlet pipeline. Such a dual-temperature faucet has the following problems: the shared water outlet pipeline is prone to temporarily store the corresponding water during the cold and hot water switching process. For example, after using cold water, part of the cold water will be temporarily stored in the water outlet pipeline. When switching to hot water, the water obtained in the initial stage is mixed with the cold water, thus bringing inconvenience to the normal drinking of users. There is another type of dual-temperature faucet that is provided with independent cold water outlets and hot water outlets.

Specific embodiments

[0030] The technical solution of the present utility model will be described and explained more clearly and completely below in conjunction with the accompanying drawings and by describing the preferred embodiments of the present utility model.

[0031] A faucet water outlet nozzle proposed by the present utility model includes an independent first water inlet channel and a second water inlet channel; a first water outlet channel communicating with the first water inlet channel; a second water outlet channel communicating with the second water inlet channel, the second water outlet channel is arranged on the periphery of the first water outlet channel and is concentric with the first water outlet channel; a second uniform water flow channel structure and a water flow shaping structure are sequentially arranged in the second water outlet channel along the water flow direction, the second uniform water flow channel structure includes a plurality of holes distributed along the circumferential direction, and the water flow shaping structure has a raised curved surface.

[0032] In the above technical solution of the faucet water outlet nozzle of the present utility model, the first water outlet flow channel penetrates through the second water outlet flow channel, and the two are concentrically arranged. While keeping the two water outlet flow channels independent of each other, the integrity of the faucet is enhanced, greatly improving the user experience.

[0033] As Figures 1 to 3 shown in the preferred embodiment, the faucet water outlet nozzle 100 includes a housing 1 and a water outlet pipe component 2. An accommodation cavity 10 is formed inside the housing 1, and the water outlet pipe component 2 is arranged in the accommodation cavity 10.

[0034] Combined with Figure 4 shown in the figure, a first water inlet flow channel 110 and a second water inlet flow channel 120 are formed on the housing 1. Specifically, a first water inlet pipe 11 and a second water inlet pipe 12 extending outward are provided on the side wall of the housing 1, and the two water inlet pipes are independent of each other. A first water inlet flow channel 110 is formed inside the first water inlet pipe 11, and a second water inlet flow channel 120 is formed inside the second water inlet pipe 12.

[0035] Combined with Figure 5 shown in the figure, the water outlet pipe component 2 includes a first water outlet pipe 21 and a top assembly flange 22. The top assembly flange 22 is used to cooperate with the top of the housing 1 and is fixed on the housing 1 by screws 3. The first water outlet pipe 21 extends downward along the vertical direction from the top assembly flange 22, and a first water outlet flow channel 210 is formed inside it. The first water outlet flow channel 210 is communicated with the first water inlet flow channel 110, so that the water flowing into the first water inlet flow channel 110 can flow out through the first water outlet flow channel 210. The top end of the first water outlet flow channel 210 has a top cover 23 for closing the top end.

[0036] A first uniform water flow channel structure 24 is arranged in the first water outlet flow channel 210, so that the water flow flowing into the first water outlet flow channel 210 from the first water inlet flow channel 110 can uniformly pass through the first uniform water flow channel structure 24, thereby becoming more stable. The first uniform water flow channel structure 24 includes a plurality of water guide sheets 240 extending along its axial direction, and the water guide sheets 240 are arranged in a radial pattern. Further, a cylinder 241 is provided at the center of the first water outlet flow channel 210, the water guide sheets 240 are radially distributed around the cylinder 241, and one side of the water guide sheets 240 is connected to the cylinder 241, and the other side is connected to the inner wall of the first water outlet pipe 21.

[0037] The water outlet pipe component 2 further includes a flow channel connection port 25, which is formed on the side wall of the first water outlet pipe 21 and is used to connect the first water inlet flow channel 110 and the first water outlet flow channel 210. A first groove 250 is formed around the flow channel connection port 25 for accommodating a first seal 41, and the first seal 41 is partially embedded in the first groove 250, so that a seal is maintained between the flow channel connection port 25 and the first water inlet flow channel 110.

[0038] The water outlet pipe component 2 is also provided with a second groove 220 on the side wall where the top assembly flange 22 mates with the inner wall of the housing 1, for accommodating the second seal 42, so as to keep the upper end of the water outlet pipe component 2 and the housing 1 sealed.

[0039] The space between the housing 1 and the water outlet pipe component 2 forms a second water flow channel 14, which is located on the periphery of the first water flow channel 210 and is concentric with the first water flow channel 210. The second water flow channel 14 communicates with the second water inlet channel 12, so that the water flowing in from the second water inlet channel 12 can flow out through the second water flow channel 14. Such a design makes the second water flow channel 14 and the first water flow channel 210 independent of each other, and the water entering from the first water inlet channel 110 and the second water inlet channel 120 will not mix inside.

[0040] Combined Figure 6 As shown, a second uniform water flow channel structure 15 and a water flow shaping structure 16 are sequentially arranged in the second water flow channel 14 along the water flow direction, and they are located on the periphery of the first water outlet pipe 21. Further, the second uniform water flow channel structure 15 includes a plurality of holes 150 distributed along the circumferential direction, so that the water flow entering the second water flow channel 14 from the second water inlet channel 120 can uniformly pass through the holes 150 and thus become more stable. The water flow shaping structure 16 has a convex curved surface 160. Specifically, the curved surface 160 protrudes from the inner side where the first water outlet pipe 21 is located towards the outer side where the housing 1 is located. Preferably, the maximum outer diameter of the curved surface 160 is less than or equal to the maximum circumferential outer diameter where the holes 150 are located. Here, the maximum circumferential outer diameter refers to the diameter of the circle where the outermost hole wall of the holes 150 is located. The advantage of such a design is that the flowing water in the second water flow channel 14 will fall onto the curved surface 160 after passing through the holes 150, and the shape of the water flow after flowing through the curved surface 160 is more beautiful.

[0041] Preferably, in this embodiment, the second uniform water flow channel structure 15 and the water flow shaping structure 16 are integrally designed, with the second uniform water flow channel structure 15 located above and the water flow shaping structure 16 located below, further enhancing the integrity of the product.

[0042] Preferably, a spoiler ring 17 is also provided in the second water flow channel 14. It is a curved surface protruding outward from the outer wall of the first water outlet pipe 21, and the spoiler ring 17 is located above the second uniform water flow channel structure 15. Further, the maximum outer diameter of the spoiler ring 17 is less than the maximum circumferential outer diameter where the holes 150 are located.

[0043] Since the water inlet channel is basically horizontal, when water flows into the housing 1 from the second water inlet channel 120 and impacts the outer wall of the water outlet pipeline component 2, the water will rotate rapidly. The rotating water will cause the water flow to be unstable. In the present utility model, a second water flow equalizing channel structure 15 is arranged in the second water outlet channel 14, and a spoiler ring 17 is arranged above the second water flow equalizing channel structure 15, so that the flow channel space is filled with water before water equalization, thereby effectively blocking the tangential flow of the water, and enabling the water to flow out along the holes 150 of the second water flow equalizing channel structure 15, further improving the stability of the water flow.

[0044] Preferably, a plurality of radially distributed water outlet holes 18 are arranged at the outlet of the second water outlet channel 14, so that the water flow in the second water outlet channel 14 flows out of the water outlet holes 18 evenly again after passing through the spoiler ring 17, the second water flow equalizing channel structure 15 and the water flow shaping structure 16, further improving the stability of the water flow and the aesthetics of the water shape.

[0045] The present utility model also proposes a water purifier faucet, which includes the above-mentioned faucet water outlet nozzle 100. When the above-mentioned faucet water outlet nozzle 100 is applied to a water purifier faucet, the first water inlet channel 110 and the second water inlet channel 120 are respectively connected to the normal temperature water outlet and the hot water outlet of the water purifier, and the first water outlet channel 210 and the second water outlet channel 14 respectively provide cold water and hot water, thereby forming a dual-temperature faucet. Of course, the second water outlet channel 14 can also be set to provide cold water, and the first water outlet channel 210 can be set to provide hot water.

[0046] Preferably, the cross-sectional area of the second water outlet channel 14 can be set to be larger than the cross-sectional area of the first water outlet channel 210, so that the water shape of the hot water flowing out of the second water outlet channel 14 is more rounded, the water column profile is thicker, the hot water flow rate is large, but the hot water flow velocity is low, which can avoid the risk of scalding caused by hot water splashing during the water receiving process of users.

[0047] The above specific embodiments only describe the preferred embodiments of the present utility model, rather than limiting the protection scope of the present utility model. Without departing from the design concept and spirit scope of the present utility model, various deformations, substitutions and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model according to the text description and drawings provided by the present utility model shall all fall within the protection scope of the present utility model. The protection scope of the present utility model is determined by the claims.
