[0029] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0031] The embodiment of the present application provides a water spout to solve the problem of intermittent hot water spraying. The embodiment will be described below with reference to the accompanying drawings.

[0032] In the embodiments of the present application, Figure 1 and Figure 2 As shown, the water outlet is provided with a slow flow chamber 21, a water vapor separation chamber 22 and a water outlet 31 which are connected in sequence. The slow flow chamber 21 is used to reduce the flow rate of water entering the water vapor separation chamber 22. A steam outlet 23 is provided on the side wall of the water vapor separation chamber 22. In this way, the slow flow chamber 21 is used to slow down the speed of hot water entering the water vapor separation chamber 22, so as to increase the contact time and contact area of ​​the hot water in the water vapor separation chamber 22, promote the water vapor in the hot water to be discharged into the steam outlet 23, reduce the water vapor content in the hot water, and finally improve the imagination of intermittent hot water spraying, and ensure the safety of users.

[0033] Exemplarily, "the slow flow chamber 21 is used to reduce the flow velocity of water entering the water vapor separation chamber 22" can be setting the flow cross-sectional area of ​​part of the slow flow chamber 21 to be smaller than the flow cross-sectional area of ​​the water inlet end of the slow flow chamber 21, or it can be setting flow blocking protrusions at different positions on the inner wall of the slow flow chamber 21 to prevent the water from falling directly and reduce the flow velocity of the water.

[0034] In some embodiments, Figure 2 As shown, the flow cross-sectional area of ​​the water outlet of the slow flow chamber 21 is smaller than the flow cross-sectional area of ​​the water inlet of the slow flow chamber 21; the flow cross-sectional area of ​​the slow flow chamber 21 decreases from the water inlet to the water outlet. In this way, the water flow velocity and flow rate are gradually reduced, which can not only promote water vapor separation by reducing the water flow velocity, but also reduce the amount of hot water in the water vapor separation chamber 22, making it easier for water vapor to escape.

[0035] In some embodiments, Figure 2 and Figure 3 As shown, the outlet end of the slow flow cavity 21 is provided with a slow flow side wall 24, and the slow flow side wall 24 is inclined. Here, the slow flow side wall 24 is inclined relative to the vertical direction or the horizontal direction, which reduces the water flow velocity on the one hand and guides the water flow direction on the other hand.

[0036] In some embodiments, Figure 2 and Figure 3 As shown, the water outlet of the slow flow cavity 21 is further provided with a flow blocking side wall 11, which is disposed between the slow flow side wall 24 and the steam outlet 23, and the slow flow side wall 24 and the flow blocking side wall 11 enclose the water outlet of the slow flow cavity 21. Here, the flow blocking side wall 11 blocks the water flow from splashing into the steam outlet 23.

[0037] In some embodiments, Figure 3 and Figure 4As shown, the slow flow chamber 21 is located in the water vapor separation chamber 22 and is spaced apart from the side wall of the water vapor separation chamber 22, and the steam outlet 23 is higher than the water outlet end of the slow flow chamber 21. In this way, increasing the longitudinal distance between the steam outlet 23 and the water outlet end of the slow flow chamber 21 is conducive to preventing water from entering the steam outlet 23.

[0038] The slow-flow side wall 24 extends toward the side wall where the steam outlet 23 is located. Here, it means that the distance between the slow-flow side wall 24 and the side wall of the water vapor separation chamber 22 where the steam outlet 23 is located gradually decreases along the water outlet end of the slow-flow chamber 21. In this way, the water flowing out from the water outlet end of the slow-flow chamber 21 flows to the side wall of the water vapor separation chamber 22 where the steam outlet 23 is located, which helps the separated steam to be quickly discharged through the steam outlet 23, thereby further optimizing the separation effect.

[0039] In some embodiments, Figure 2 , Figure 3 and Figure 4 As shown, a steam flow channel 4 is also provided, and the steam flow channel 4 is arranged at intervals on the circumferential side of the water vapor separation chamber 22, and the steam outlet 23 connects the steam flow channel 4 and the water vapor separation chamber 22; in this way, the steam discharge path is extended through the steam flow channel 4 to prevent the splashing liquid in the water vapor separation chamber 22 from flowing out from other directions except the water outlet end of the water outlet nozzle.

[0040] In some embodiments, the steam outlet 23 is arranged obliquely, and the steam inlet end of the steam outlet 23 is lower than the steam outlet end of the steam outlet 23. Here, the steam outlet 23 is arranged obliquely relative to the vertical direction or the horizontal direction; the steam inlet end of the steam outlet 23 is lower than the steam outlet end of the steam outlet 23 means: the end of the steam outlet 23 connected to the water vapor separation chamber 22 is lower than the end of the steam outlet 23 connected to the steam flow channel 4. In this way, it is conducive to guiding the rising steam into the steam flow channel 4 through the steam outlet 23, and accelerating the discharge of steam.

[0041] In some specific embodiments, Figure 2 and Figure 3 As shown, the steam channel 4 extends along the axial direction of the water outlet and penetrates the water outlet end of the water outlet, so that the generated steam and hot water flow out from the water outlet in the same direction, which is not easy to detect.

[0042] In some specific embodiments, Figure 3 As shown, a plurality of steam outlets 23 are provided.

[0043] In some embodiments, Figure 4 and Figure 5As shown, the water outlet part 31 includes a diverter plate 311 and a water outlet plate 312 which are arranged in sequence along the water flow direction; the diverter plate 311 is fixedly connected to the water outlet end of the water outlet nozzle, and a plurality of protrusions 314 are provided on the side of the diverter plate 311 facing the water outlet plate 312, a plurality of diverter holes 32 are provided on the diverter plate 311, and a plurality of water passing holes 33 are provided on the water outlet plate 312. The plurality of diverter holes 32 and the plurality of water passing holes 33 are connected, and the water outlet plate 312 can be movably mounted on the protrusion 314 or detached from the protrusion 314. When the water outlet is used for a long time, the water is heated by the heating device, and the calcium bicarbonate and magnesium bicarbonate in the water are gradually decomposed, so that the concentration of calcium and magnesium salts in the water increases until it is higher than the solubility at the current temperature, and calcium carbonate and magnesium hydroxide that are insoluble in water are precipitated. The water hole 33 is easily blocked by scale, resulting in water failure. Therefore, by pushing the water outlet plate 312, the protrusion 314 on the diverter plate 311 facing the water outlet plate 312 passes through the water hole 33 of the water outlet plate 312 to puncture and remove the scale, thereby ensuring normal water output.

[0044] In some embodiments, Figure 4 and Figure 5 As shown, the water outlet part 31 also includes a water outlet cover plate 313, which is located on the side of the water outlet plate 312 away from the diverter plate 311, and the water outlet cover plate 313 is fixedly connected to the water outlet end of the water outlet nozzle. The diverter plate 311 and the water outlet cover plate 313 jointly limit the movement range of the water outlet plate 312.

[0045] The water outlet cover plate 313 is provided with a water outlet hole 34 and an avoidance hole 36 , the water outlet hole 34 is connected with the water through hole 33 , and the water outlet plate 312 is provided with a pressing protrusion 315 , which passes through the avoidance hole 36 to allow external force to push the water outlet plate 312 .

[0046] In some embodiments, the water outlet portion 31 further includes a reset member 35 , which is located between the diverter plate 311 and the water outlet plate 312 , and is used to push the water outlet plate 312 toward the water outlet cover plate 313 .

[0047] Here, the reset member 35 refers to a structure capable of restoring the water outlet plate 312 to an initial position; illustratively, the reset member 35 may be a spring or a compression sheet having elasticity. Figure 7 , Figure 8 and Fig. 9 As shown, in this way, the pressing protrusion 315 is pushed upward by external force, the reset member 35 is compressed, and the water outlet plate 312 moves upward, so that the protrusion 314 on the diverter plate 311 is inserted into the water hole 33 on the water outlet plate 312 to achieve descaling, and the pressing protrusion 315 of the water outlet plate 312 is released, and the reset member 35 is reset, so that the water outlet plate 312 returns to its original state, that is, it is against the water outlet cover plate 313, and at this time, the water hole 33 of the water outlet plate 312 is separated from the protrusion 314 on the diverter plate 311, so that water can be discharged normally.

[0048] In some specific embodiments, the protrusion 314 is a truncated cone structure, and one end of the protrusion 314 facing the water outlet cover plate 313 is set to be flat-bottomed. In this way, the end of the protrusion 314 with a flat bottom is not easy to damage the water hole 33.

[0049] In some specific embodiments, Figure 4 , Figure 5 and Figure 6 As shown, the water outlet part 31 also includes a water outlet lower shell 3, a diverter plate 311, a water outlet plate 312 and a water outlet cover plate 313 are arranged in the water outlet lower shell 3, a sealing ring is provided between the diverter plate 311 and the water outlet lower shell 3, and a sealing ring is provided between the water outlet cover plate 313 and the water outlet lower shell 3, which can prevent water from flowing out from the surrounding gaps.

[0050] In some embodiments, at least some of the water outlet holes 34 and at least some of the water through holes 33 are arranged in a one-to-one correspondence, and the central axes of the correspondingly arranged water outlet holes 34 and water through holes 33 coincide with each other. In this way, water can flow through the water through holes 33 and water outlet holes 34 quickly.

[0051] In some embodiments, at least some of the flow diverter holes 32 and at least some of the water passing holes 33 are not arranged one by one, but are arranged in a staggered manner. In this way, the multiple flow diverter holes 32 and water passing holes 33 that are not arranged in a corresponding manner can disrupt the water flow, so that the water will not fill the water outlet, which is conducive to the separation of water vapor and reduces the kinetic energy of the water. After the water is stored in the container, it is not easy to generate liquid splashing and loud noise.

[0052] In some embodiments, Figure 4 , Figure 5 and Figure 6 As shown, a plurality of water inlet holes 37 are provided on one end of the water outlet 31 facing the water vapor separation chamber 22, and the total cross-sectional area of ​​the plurality of water inlet holes 37 is larger than the cross-sectional area of ​​the lower end of the water vapor separation chamber 22. In this way, a single water column is divided into multiple water columns, which is convenient for further separation of water vapor on the one hand, and is convenient for reducing kinetic energy of water and noise on the other hand.

[0053] Furthermore, in some specific embodiments, the water outlet portion 31 also includes a water outlet inner shell 316, a diverter plate 311, a water outlet plate 312 and a water outlet cover plate 313 are arranged in the water outlet inner shell 316, and a plurality of water inlet holes 37 are arranged at the end of the water outlet inner shell 316 facing the water vapor diversion cavity.

[0054] In some embodiments, Figure 4 As shown, the water outlet nozzle includes an upper water outlet shell 1, a middle water outlet shell 2 and a lower water outlet shell 3 which are connected in sequence. The water outlet end of the upper water outlet shell 1 and the water inlet end of the water outlet shell 2 are positioned and matched by a stopper and connected by ultrasonic welding. The water outlet end of the middle water outlet shell 2 and the water inlet end of the lower water outlet shell 3 are positioned and matched by a stopper and connected by ultrasonic welding.

[0055] Furthermore, the flow-blocking side wall 11 is arranged at the water outlet end of the water outlet upper shell 1 and extends into the water outlet middle shell 2, the slow-flow side wall 24 is arranged in the water outlet shell 2 to form a slow-flow cavity 21 with the flow-blocking side wall 11, the water vapor separation cavity 22 and the upper part of the steam flow channel 4 are formed in the water outlet shell 2, the water outlet part 31 is formed in the water outlet lower shell 3, and the water outlet lower shell 3 also includes a water outlet outer shell 317, and the water outlet outer shell 317 is arranged on the outside of the water outlet inner shell 316 to form the lower part of the steam flow channel 4.
