DETAILED DESCRIPTION

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Combination Figures 1 to 3The water outlet device 100 of the drinking water equipment 1000 according to the embodiment of the present invention includes: a shell, the shell has an inlet 101, an outlet 102, a first flow channel 110 and a second flow channel 120, the first flow channel 110 and the second flow channel 120 extend in the up-down direction, the upper end of the first flow channel 110 is connected to the inlet 101 and the lower end is connected to the outlet 102, the upper end of the second flow channel 120 is connected to the upper end of the first flow channel 110 and the lower end is connected to the outlet 102.

[0034] Specifically, the upper end of the first flow channel 110 is connected to the inlet 101 and the lower end is connected to the outlet 102, and the first flow channel 110 extends in the up-down direction, so that water can enter the first flow channel 110 from the inlet 101 and automatically flow downward based on gravity, and flow out from the outlet 102, thereby realizing the water outlet function of the water outlet device 100. Furthermore, when the water outlet device 100 discharges high-temperature hot water or boiling water, water vapor accompanies the water outlet process. If water and water vapor flow out of the outlet 102 in a mixed state, the water flow out of the outlet 102 will be discontinuous and unstable, resulting in intermittent water outlet, drifting or dispersion, etc. The irregular water outlet trajectory of the hot water and the mixing of water vapor can easily scald the user, posing a safety hazard. Therefore, when the water outlet device 100 discharges high-temperature hot water or boiling water, after the hot water enters the housing from the inlet 101, the water can flow downward through the first flow channel 110 and out of the outlet 102, so that the hot water flowing out of the first flow channel 110 is stable and the water output is round; and the water vapor can flow upward to the second flow channel 120 connected to the upper end of the first flow channel 110, and the water vapor enters the second flow channel 120 and is discharged from the outlet 102. It should be noted that the second flow channel 120 can realize water vapor separation and provide an airflow path, and can also extend the flow path of the high-temperature airflow or water vapor, reducing the risk of high-temperature airflow injuring people.

[0035] Furthermore, combined with Figure 2The water outlet device 100 also includes a guide part 20, which extends in the up-down direction, and the upper end is connected to the lower periphery of the second flow channel 120. The peripheral wall of the guide part 20 is provided with a hollow structure 201, which can improve the stability of water outlet. Specifically, when the water outlet flow rate is large, part of the water entering the inlet 101 flows out from the first flow channel 110. Due to the large water flow rate, part of the water can overflow from the first flow channel 110 to the second flow channel 120, that is, part of the water can flow out from the second flow channel 120, which can play a buffering effect, slow down the impact of the water flow, and ease the water outlet flow. When the water flows to the lower end of the second flow channel 120, the water can be guided to flow downward through the guide part 20, thereby improving the water outlet stability and the shape of the water outlet and the water outlet stability. At the same time, the hollow structure 201 of the guide part 20 can make the second flow channel 120 communicate with the atmosphere, so that a large flow of water can be evenly gathered in the second flow channel 120, preventing the formation of a water film, resulting in a negative pressure inside the water outlet device 100, and the remaining water is accumulated in the cavity, thereby helping to improve the water outlet stability and water outlet effect when a large flow of water is discharged.

[0036] According to the water outlet device 100 of the drinking water equipment 1000 according to the embodiment of the present invention, by providing the second flow channel 120 connected to the first flow channel 110, a water vapor separation effect can be achieved when discharging high-temperature water, thereby improving the water outlet stability; when discharging a large flow of low-temperature water, water can overflow from the first flow channel 110 to the second flow channel 120, so that water can be discharged from the first flow channel 110 and the second flow channel 120 at the same time, and a guide part 20 for guiding the water flow is provided at the lower end of the second flow channel 120, and a hollow structure 201 connected to the atmosphere is provided at the lower end of the guide part 20, which can prevent the formation of negative pressure in the water outlet device 100 and improve the water outlet effect.

[0037] It should be noted that the water outlet device 100 can discharge low-flow high-temperature water. Since the water outlet flow rate is low, the high-temperature water can all flow from the first flow channel 110, and the high-temperature water vapor enters the second flow channel 120 and is discharged from the second flow channel 120. The water outlet device 100 can discharge a large flow of low-temperature water. At this time, after the water enters the first flow channel 110, a part of it flows directly out of the first flow channel 110, and a part overflows to the second flow channel 120 and flows out of the second flow channel 120. The guide part 20 at the lower end of the second flow channel 120 can be used to guide the water flow and improve the stability of the water outlet. The hollow structure 201 of the guide part 20 can also balance the air pressure inside and outside the water outlet device 100 and improve the smoothness of the water outlet. Alternatively, the water outlet device 100 can discharge a large amount of high-temperature water, so that part of the water can flow out from the first flow channel 110, and part of the high-temperature water and high-temperature water vapor can overflow into the second flow channel 120. At the lower end of the second flow channel 120, the high-temperature steam can be discharged from the hollow structure 201, and the high-temperature water can be drained out through the drainage part.

[0038] Combination Figure 3In some embodiments of the present invention, the second flow channel 120 is arranged around the first flow channel 110, which can improve the flow effect of water or high-temperature water vapor from the first flow channel 110 to the second flow channel 120. In actual application, water overflowing from the first flow channel 110 can enter the second flow channel 120 along the circumferential direction, and the steam can also enter the second flow channel 120 along the circumferential direction, which is beneficial to improve the water or steam inlet flow rate and uniformity.

[0039] In some other embodiments of the present invention, the second flow channel 120 is disposed on one side of the first flow channel 110 , for example, the second flow channel 120 can be disposed side by side with the first flow channel 110 .

[0040] Combination Figure 3 and Figure 6 In some embodiments of the present invention, the housing includes a first housing 11 and a second housing 12, the first housing 11 is disposed around the outside of the second housing 12, the first flow channel 110 is disposed inside the second housing 12, and the second flow channel 120 is disposed between the first housing 11 and the second housing 12. For example, the first flow channel 110 and the second flow channel 120 are coaxially disposed, and the second flow channel 120 is disposed outside the first flow channel 110, so that the water or gas in the first flow channel 110 can flow to the second flow channel 120 along the circumferential direction, which is conducive to improving the uniformity of the flow rate and circulation, thereby improving the water and gas outlet effects, and can also improve the compactness of the structure, which is conducive to miniaturization of the water outlet device 100.

[0041] In some embodiments of the present invention, the upper edge of the guide portion 20 is connected to the lower edge of the first shell 11, so that when the guide portion 20 is used, water or gas discharged from the second flow channel 120 can be discharged from the second flow channel 120 through the guide portion 20, which is beneficial to improving the water outlet effect.

[0042] In some embodiments of the present invention, the guide portion 20 surrounds the lower end of the second shell 12 and is inclined inward in the extending direction from top to bottom, so as to guide the water flowing out of the second flow channel 120 to flow toward the outlet 102 of the first flow channel 110. When the user receives water, the water outflows of the first flow channel 110 and the second flow channel 120 can be gathered together and flow out from the outlet 102, which is beneficial to improve the water outlet effect. In addition, there is a gap between the lower periphery of the guide portion 20 and the lower end of the second shell 12, and the gap can provide a certain water outlet space for the second flow channel 120, so as to prevent the water outflow of the second flow channel 120 from mixing into the water outflow of the first flow channel 110, but gradually converge with the first flow channel 110 at the outlet 102, so that the water outlet shape is round and stable, without interruption or shaking.

[0043] In some embodiments of the present invention, the guide portion 20 is inclined inward in the extending direction from top to bottom, so as to guide the water flow inward to merge with the water flow of the first flow channel 110, thereby improving the water outlet effect.

[0044] In some embodiments of the present invention, the hollow structure 201 includes multiple ones distributed along the circumference of the guide portion 20, which can improve the connectivity between the water outlet device 100 or the second flow channel 120 and the external atmosphere, improve the internal and external air pressure balance of the water outlet device 100, and help to improve the uniform convergence of the water flow in the second flow channel 120. It can also avoid water being squeezed in the flow channel, which is beneficial to improving the water outlet effect.

[0045] Combination Figure 2 In some embodiments of the present invention, the guide portion 20 includes a plurality of guide ribs 21, and the plurality of guide ribs 21 are spaced apart along the guide portion 20, and a hollow structure 201 is provided between adjacent guide ribs 21. The guide ribs 21 can be used to guide water flow, and the plurality of guide ribs 21 can improve the water flow diversion effect. The plurality of guide ribs 21 spaced apart can guide and disperse the water flow, improve the uniformity of the water flow, and can also form a hollow structure 201 connecting the inside and outside of the second flow channel 120 at the interval between two guide ribs 21.

[0046] In some embodiments of the present invention, the guide ribs 21 are constructed in a form in which the width gradually decreases from top to bottom, which can guide the flow of water, help improve the diversion effect, improve the fluid flow state, and thus improve the water outflow form.

[0047] In some embodiments of the present invention, the guide part 20 includes a reinforcing rib 22, and the reinforcing rib 22 connects a plurality of guide ribs 21. The reinforcing rib 22 can connect a plurality of guide ribs 21 extending in the up-down direction, which is beneficial to improve the structural strength and structural stability of the guide part 20. When the guide part 20 is impacted by water flow, it can disperse the force. Specifically, in combination with Figure 3 The reinforcing rib 22 is connected to the middle part of the guide rib 21 along the up-down direction. The plurality of guide ribs 21 and the reinforcing rib 22 form an integral structure.

[0048] In some embodiments of the present invention, Figure 2 The housing further includes a third housing 13, the outlet 102 is disposed in the third housing 13, the flow guide 20 is disposed in the third housing 13, and the lower end of the first flow channel 110 is disposed in the third housing 13. The third housing 13 can shield the outlet 102 and the flow guide 20, so that the water flowing out of the first flow channel 110 and the water flowing out of the flow guide 20 or the discharged steam can be in the third housing 13, thereby preventing the water from splashing or the steam from diffusing, facilitating the water to be collected, and improving the water discharge effect.

[0049] Combination Figure 4 and Figure 6In some embodiments of the present invention, the housing further comprises a fourth housing 14, an inlet 101 is provided in the fourth housing 14, a lower portion of the fourth housing 14 extends into the first flow channel 110, a lower end of the fourth housing 14 is closed, and a connecting hole 104 is provided at the lower periphery, and the connecting hole 104 is connected to the first flow channel 110. Specifically, the incoming water can enter from the inlet 101 of the fourth housing 14, and then flow into the first flow channel 110 from the connecting hole 104 at the lower periphery. Since the lower end of the fourth housing 14 is closed, the impact force of the water flow can be mitigated. A plurality of connecting holes 104 are provided along the lower periphery. When the water flows out from the plurality of connecting holes 104, a slow flow effect can be achieved, so that the flow rate of the incoming water entering the first flow channel 110 is relatively stable, and then the water flows out from the first flow channel 110.

[0050] When high-temperature water enters the fourth shell 14, the water flow rate can be slowed down when the high-temperature water flows out through the connecting hole 104, which is conducive to water vapor separation. When the steam is discharged from the connecting hole 104, it can enter the second flow channel 120. Therefore, the high-temperature water flowing out of the connecting hole 104 enters the first flow channel 110 for circulation. After entering the first flow channel 110, the high-temperature steam moves upward and can enter the second flow channel 120 connected to the upper end of the first flow channel 110 and flow out from the second flow channel 120. When the water inlet flow rate is large, a large amount of water enters the fourth shell 14 from the inlet 101. The impact force of the water with a large flow rate is relatively large. The closed structure at the lower end of the fourth shell 14 and the connecting holes 104 at the periphery can form a buffer structure. When the large flow rate of water enters the first flow channel 110 through the buffer structure, a slow flow can be achieved. A part of the water can overflow from the first flow channel 110 to the second flow channel 120 connected to the upper end of the first flow channel 110 to achieve a second slow flow, which can further reduce the impact force of the water flow. The water in the first flow channel 110 and the second flow channel 120 converge at the outlet 102, which can improve the stability and uniformity of the water outlet.

[0051] In some embodiments of the present invention, Figure 4 and Figure 6 The connecting hole 104 is configured in a grid shape, which can improve the uniformity of the water outflow and improve the effect of reducing the impact of the water flow. Specifically, when the water flows from the fourth shell 14 into the first flow channel 110, it is blocked by the closed end of the fourth shell 14 and the surrounding wall, which has a buffering effect. The water flow rate flowing out of the connecting hole 104 is relatively stable, and the connecting effect between the fourth shell 14 and the first flow channel 110 is improved.

[0052] Combination Figure 6 There is an arc-shaped transition between the lower periphery of the fourth shell 14 and the lower closed end, which can play a guiding effect and is easy to shape during manufacturing.

[0053] In other embodiments of the present invention, Figure 4A guide plate is provided at the periphery of the lower end of the fourth shell 14, and the closed end is provided on the inner side of the guide plate.

[0054] Combination Figure 6 In some embodiments of the present invention, the first flow channel 110 includes a first flow segment 10a and a second flow segment 10b connected in the up-down direction, and the inner diameter of the second flow segment 10b is smaller than the inner diameter of the first flow segment 10a. In other words, the inner diameter of the upper part of the first flow channel 110 is larger than the inner diameter of the lower part. During the water flow process, the flow channel of the first flow channel 110 becomes narrower, which can play a role in converging. A step structure is constructed between the first flow segment 10a and the second flow segment 10b. When the water flows to the step structure, the step structure can have a slow flow effect, reduce water pulsation, and improve the water outlet effect. In other words, in the first flow channel 110, the flow channel is in the form of progressive contraction from top to bottom.

[0055] The lower part of the fourth housing 14 is located at the upper part of the first flow section 10a, so that the water flow can continue to flow for a distance in the first flow channel 110 after flowing out of the connecting hole 104, which is conducive to the stability of the water flow when the water flows to the outlet 102. The lower part of the fourth housing 14 is located at the upper part of the first flow section 10a, which means that the distance between the lower end of the first flow section 10a and the lower end of the fourth housing 14 is large. The increase in the space of the first flow section 10a is conducive to increasing the water flow space, thereby facilitating an increase in the water output.

[0056] Specifically, the lower portion of the fourth housing 14 located above the first flow segment 10a may be located at 1 / 2 of the length of the first flow segment 10a in the vertical direction, or at a flow segment above 1 / 2; or may be located at 2 / 3 or above of the length of the first flow segment 10a in the vertical direction. In short, there is a certain gap between the lower portion of the fourth housing 14 and the lower end of the first flow segment 10a, which is conducive to extending the flow path of water.

[0057] Furthermore, combined with Figure 6In some embodiments of the present invention, the first flow channel 110 includes a third flow segment 10c connected to the second flow segment 10b in the up-down direction, and a step structure is constructed between the third flow segment 10c and the second flow segment 10b, and the inner diameter of the third flow segment 10c is smaller than the inner diameter of the second flow segment 10b. In other words, the third flow segment 10c is also reduced relative to the second flow segment 10b, which has the effect of converging. The step structure between the second flow segment 10b and the third flow segment 10c can further play a slow flow effect, thereby improving the water outlet stability. Therefore, in the direction from top to bottom, the first flow segment 10a, the second flow segment 10b and the third flow segment 10c construct a progressive structure, the flow segment cross-sectional area gradually decreases, and the two step structures can play the effect of gradually slowing down the water flow velocity during the circulation process, improve the buffering effect on the water flow, so that the water flow at the outlet 102 can be discharged in a straight line. Especially when the high-temperature water flow rate is large, the water outlet effect of the high-temperature water can be improved, thereby improving the water outlet stability and avoiding scalding users.

[0058] Combination Figure 4 In some embodiments of the present invention, the second shell 12 includes a first section 121 and a second section 122 connected in the up-down direction, and the second shell 12 is provided with a plurality of first support plates 124, and the plurality of first support plates 124 extend from the first section 121 to the second section 122 in the up-down direction, and the first support plates 124 are supported between the first shell 11 and the second shell 12. Specifically, the first support plate 124 of the first section 121 can be supported between the inner wall of the first shell 11 and the first section 121 of the second shell 12, so as to construct the second flow channel 120, which is beneficial to improve the stability of the water outlet device 100. The first support plate 124 of the second section 122 can be supported between the first shell 11 and the second shell 12 in the lateral or left-right direction, and can also be supported between the first shell 11 and the second shell 12 in the up-down direction, thereby, a flow channel from the second flow channel 120 to the guide portion 20 can be constructed between the plurality of first support plates 124 (see Figure 6 That is to say, the first support plate 124 can not only construct a flow channel for water and gas, but also improve the structural stability of the assembly of the first shell 11 and the second shell 12.

[0059] Furthermore, the second shell 12 is cylindrical, and the outer diameter of the second section 122 is smaller than the outer diameter of the first section 121. Thus, at the lower end of the second flow channel 120, the flow channel of the second flow channel 120 near the outlet 102 becomes larger, or the flow channel of the second flow channel 120 becomes larger at the position where the first section 121 and the second section 122 are connected, which can reduce the flow velocity of the water flow, help alleviate the impact force of the water flow, help reduce pressure, help improve the stability of the water flow, reduce eddy currents and turbulence, and ensure smooth water flow.

[0060] Combination Figure 6The flow area of ​​the first flow channel 110 gradually decreases in the direction approaching the outlet 102, while the flow area of ​​the second flow channel 120 gradually expands in the direction approaching the outlet 102. As a result, the flow velocities of the water outlets of the first flow channel 110 and the second flow channel 120 at the outlet 102 are slightly different, so that the water of the first flow channel 110 and the second flow channel 120 flowing out of the outlet 102 can easily merge together, and the shape of the water outlet after the merger is round and stable, which can improve the user experience.

[0061] In some embodiments of the present invention, the second housing 12 further includes a third section 123, the outer diameter of the second section 122 is greater than the outer diameter of the third section 123, and the flow guide 20 surrounds the third section 123 and has a gap with the third section 123. Thus, the third section 123 can provide a flow guide space for the flow guide 20, thereby improving the water outlet effect of the water flowing out of the second flow channel 120.

[0062] In some embodiments of the present invention, the third section 123 is constructed into a tube that gradually shrinks from top to bottom, which is conducive to gathering water flow and improving the water outlet effect. The tubular outer wall of the third section 123 can also cooperate with the guide part 20 to play a guide effect when the water outlet of the second flow channel 120 is large.
