[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] Combination Figures 1 to 6 According to an embodiment of the present invention, the water outlet device 100 of the drinking water equipment 1000 includes: a first housing 11 and a second housing 12. The first housing 11 has an inlet 101, an outlet 102, and a first flow channel 110. The second housing 12 is disposed inside the first housing 11, and the first flow channel 110 is disposed inside the second housing 12, forming a second flow channel 120 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 arranged, and the second flow channel 120 is disposed outside the first flow channel 110. In this way, water or gas in the first flow channel 110 can flow circumferentially to the second flow channel 120, which helps to improve the flow rate and uniformity of circulation, thereby improving the water and gas output effect, and also improving the compactness of the structure, which is conducive to realizing the miniaturization of the water outlet device 100.

[0036] Specifically, the first flow channel 110 and the second flow channel 120 extend in the vertical 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.

[0037] More 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. The first flow channel 110 extends vertically, allowing water to enter the first flow channel 110 from the inlet 101 and flow downwards automatically due to gravity, exiting from the outlet 102, thus realizing the water outlet function of the water outlet device 100. Furthermore, when the water outlet device 100 dispenses high-temperature hot water or boiling water, water vapor is present during the water dispensing process. If water and water vapor flow out of the outlet 102 in a mixed state, the water flow at the outlet 102 will be discontinuous and unstable, resulting in intermittent, drifting, or dispersed water dispensing. The irregular trajectory of the hot water and the mixing of water and vapor can easily scald users, posing a safety hazard. Therefore, when the water outlet device 100 dispenses high-temperature hot water or boiling water, the hot water enters the casing through inlet 101 and flows downwards through the first flow channel 110 and out through outlet 102. This results in a stable flow of hot water from the first flow channel 110 and a smooth, rounded outlet shape. Meanwhile, water vapor flows upwards to the second flow channel 120, which is connected to the upper end of the first flow channel 110. The water vapor enters the second flow channel 120 and exits through outlet 102. It should be noted that the second flow channel 120 not only separates water vapor and provides an airflow path, but also extends the flow path of the high-temperature airflow or water vapor, reducing the risk of injury from the high-temperature airflow.

[0038] Furthermore, combined Figure 2 The water outlet device 100 also includes a guide section 20, which extends vertically and connects at its upper end to the lower periphery of the second flow channel 120. The peripheral wall of the guide section 20 has a hollow structure 201, which can improve the stability of the water outlet. Specifically, when the water flow rate is large, part of the water entering through the inlet 101 flows out through the first flow channel 110. Due to the large water flow rate, some water can overflow from the first flow channel 110 to the second flow channel 120, that is, some water can flow out through the second flow channel 120, which can play a buffering role, reduce the impact force of the water flow, and moderate the water flow. When the water flows to the lower end of the second flow channel 120, it can be guided downward by the guide section 20, which improves the stability of the water outlet and the shape of the water outlet. At the same time, the hollow structure 201 of the guide section 20 can make the second flow channel 120 open to the atmosphere, so that the large flow of water can be evenly collected in the second flow channel 120, preventing the formation of a water film and causing negative pressure to be formed inside the water outlet device 100, which will accumulate the excess water in the cavity, thereby improving the water outlet stability and water outlet effect when the large flow of water is discharged.

[0039] According to an embodiment of the present invention, the water outlet device 100 of the drinking water equipment 1000, by setting a second flow channel 120 that connects to the first flow channel 110, can achieve water vapor separation when discharging high-temperature water, thereby improving the stability of water discharging; 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 the first flow channel 110 and the second flow channel 120 discharge water simultaneously. Furthermore, a guide section 20 for guiding 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 section 20, which can prevent the formation of negative pressure inside the water outlet device 100 and improve the water discharging effect.

[0040] It should be noted that the water outlet device 100 can discharge high-temperature water at a low flow rate. Due to the low flow rate, all the high-temperature water can flow through the first channel 110, and the high-temperature water vapor enters the second channel 120 and is discharged from the second channel 120. The water outlet device 100 can also discharge low-temperature water at a high flow rate. In this case, after the water enters the first channel 110, part of it flows directly out of the first channel 110, and part overflows into the second channel 120 and flows out from the second channel 120. The guide section 20 at the lower end of the second channel 120 can be used to guide the water flow and improve the stability of the water discharge. The hollow structure 201 of the guide section 20 can also balance the air pressure inside and outside the water outlet device 100, improving the smoothness of the water discharge. Alternatively, the water outlet device 100 can output high-temperature water with a large flow rate. In this way, some water can flow out from the first flow channel 110, and some high-temperature water and high-temperature water vapor can overflow to the second flow channel 120. At the lower end of the second flow channel 120, high-temperature steam can be discharged from the hollow structure 201, and high-temperature water can be drained out through the diversion part.

[0041] Combination Figure 3 In some embodiments of this utility model, 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, the water overflowing from the first flow channel 110 can enter the second flow channel 120 in the circumferential direction, and the vapor can enter the second flow channel 120 in the circumferential direction, which is conducive to improving the flow rate and uniformity of water or steam.

[0042] 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 may be disposed side by side with the first flow channel 110.

[0043] In some embodiments of this utility model, the upper edge of the guide section 20 is connected to the lower edge of the first housing 11, which facilitates the application of the guide section 20. Water or gas discharged from the second flow channel 120 can be discharged through the guide section 20 from the second flow channel 120, which helps to improve the water output effect.

[0044] In some embodiments of this utility model, the guide portion 20 surrounds the lower end of the second housing 12 and slopes inward in the downward extending direction. It can guide the water flowing out from the second flow channel 120 toward the outlet 102 of the first flow channel 110. When the user collects water, the water from the first flow channel 110 and the second flow channel 120 can converge and flow out from the outlet 102, which helps to improve the water output effect. In addition, there is a gap between the lower periphery of the guide portion 20 and the lower end of the second housing 12. The gap can provide a certain water output space for the second flow channel 120, preventing the water from the second flow channel 120 from mixing with the water from the first flow channel 110. Instead, the water gradually merges with the first flow channel 110 at the outlet 102, making the water output shape smooth and stable, without interruption or shaking.

[0045] In some embodiments of this utility model, the guide portion 20 is inclined inward in the downward extending direction, which can guide the water flow inward to merge with the water flow in the first flow channel 110, thereby improving the water output effect.

[0046] In some embodiments of this utility model, the hollow structure 201 includes a plurality of hollow structures distributed circumferentially along the guide portion 20, which can improve the communication effect 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, facilitate the uniform collection of water flow in the second flow channel 120, and prevent water from being squeezed into the flow channel, thereby improving the water outlet effect.

[0047] Combination Figure 2 In some embodiments of this utility model, the flow guiding part 20 includes a plurality of flow guiding ribs 21, which are spaced apart along the flow guiding part 20, and a hollow structure 201 is provided between adjacent flow guiding ribs 21. The flow guiding ribs 21 can be used to guide water flow, and the plurality of flow guiding ribs 21 can improve the flow guiding effect. The spaced distribution of the plurality of flow guiding ribs 21 can guide and disperse water flow, improve the uniformity of water flow, and also form a hollow structure 201 connecting the inside and outside of the second flow channel 120 at the interval between two flow guiding ribs 21.

[0048] In some embodiments of this utility model, the guide rib 21 is configured such that its width gradually decreases from top to bottom, which can guide the water flow, improve the guiding effect, improve the fluid flow state, and thus improve the water outflow pattern.

[0049] In some embodiments of this utility model, the flow guide 20 includes a reinforcing rib 22, which connects multiple flow guide ribs 21. The reinforcing rib 22 can connect multiple flow guide ribs 21 extending in the vertical direction, which helps to improve the structural strength and stability of the flow guide 20. When the flow guide 20 is impacted by water flow, it can disperse the force. Specifically, combined with Figure 3The reinforcing rib 22 is connected to the middle of the guide rib 21 along the vertical direction. Multiple guide ribs 21 and reinforcing ribs 22 form a structure as a whole.

[0050] In some embodiments of this utility model, combined with Figure 2 The housing also includes a third housing 13, with an outlet 102 disposed within the third housing 13, a guide section 20 disposed within the third housing 13, and the lower end of the first flow channel 110 disposed within the third housing 13. The third housing 13 can shield the outlet 102 and the guide section 20, allowing water flowing out of the first flow channel 110 and water or exhaust gas flowing out of the guide section 20 to remain within the third housing 13, thereby preventing water splashing or steam diffusion, facilitating water collection, and improving water output efficiency.

[0051] Combination Figure 4 and Figure 6 In some embodiments of this utility model, the housing further includes a fourth housing 14, an inlet 101 disposed in the fourth housing 14, the lower part of the fourth housing 14 extending into the first flow channel 110, the lower end of the fourth housing 14 being closed, and a connecting hole 104 being provided on the lower periphery, the connecting hole 104 communicating with the first flow channel 110. Specifically, 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 on the lower periphery. Since the lower end of the fourth housing 14 is closed, it can mitigate the impact force of the water flow. Multiple connecting holes 104 are provided along the lower periphery, and when the water flows out from the multiple connecting holes 104, it can have a slowing effect, making the flow rate of the water entering the first flow channel 110 relatively stable, and then flowing out from the first flow channel 110.

[0052] When high-temperature water enters the fourth shell 14, the water flow rate is slowed down when it 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. Thus, 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 vapor moves upward and can enter the second flow channel 120 connected to the upper end of the first flow channel 110, and then flow out from the second flow channel 120. When the inlet flow rate is large, a large amount of water enters the fourth housing 14 from the inlet 101. The impact force of the large flow rate is large. The closed structure at the lower end of the fourth housing 14 and the connecting holes 104 on the periphery can form a buffer structure. When the large flow rate of water enters the first flow channel 110 through the buffer structure, it can achieve a slow flow. Some 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 output.

[0053] In some embodiments of this utility model, combined with Figure 4 andFigure 6 The connecting hole 104 is designed in a grid shape, which can improve the uniformity of water flow and enhance the effect of mitigating the impact force of water flow. Specifically, when water flows from the fourth housing 14 into the first flow channel 110, it is blocked by the closed end of the fourth housing 14 and the peripheral wall, which has a buffering effect. The water flow velocity flowing out of the connecting hole 104 is relatively stable, and the communication effect between the fourth housing 14 and the first flow channel 110 is improved.

[0054] Combination Figure 6 The lower periphery of the fourth shell 14 and the lower closed end are arc-shaped transitions, which can play a guiding role and are easy to form during manufacturing.

[0055] In other embodiments of this utility model, combined with Figure 4 The lower periphery of the fourth housing 14 is provided with a guide plate, and the closed end is located inside the guide plate.

[0056] Combination Figure 6 In some embodiments of this utility model, the first flow channel 110 includes a first flow section 10a and a second flow section 10b connected in the vertical direction, with the inner diameter of the second flow section 10b being smaller than the inner diameter of the first flow section 10a. That is, the upper inner diameter of the first flow channel 110 is larger than the lower inner diameter. During water flow, the flow channel of the first flow channel 110 narrows, which can serve as a confluence. A stepped structure is constructed between the first flow section 10a and the second flow section 10b. When water flows to the stepped structure, the stepped structure can slow down the flow, reduce water pulsation, and improve the water output. Alternatively, the flow channel 110 gradually narrows from top to bottom.

[0057] The lower part of the fourth shell 14 is located above the first flow section 10a. This allows the water to continue flowing for a distance within the first flow channel 110 after exiting the connecting hole 104, improving the stability of the water flow when it reaches the outlet 102. The lower part of the fourth shell 14 being located above the first flow section 10a means that the distance between the lower end of the first flow section 10a and the lower end of the fourth shell 14 is relatively large. This increased space in the first flow section 10a improves the water flow space, thereby increasing the output water volume.

[0058] Specifically, the lower part of the fourth shell 14, located above the first flow section 10a, can be at or above 1 / 2 of the vertical length of the first flow section 10a; or it can be at or above 2 / 3 of the vertical length of the first flow section 10a. In general, there is a certain gap between the lower part of the fourth shell 14 and the lower end of the first flow section 10a, which facilitates extending the water flow path.

[0059] Furthermore, combined Figure 6In some embodiments of this utility model, the first flow channel 110 includes a third flow segment 10c that connects to the second flow segment 10b in the vertical direction. A stepped 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 that of the second flow segment 10b. That is, the third flow segment 10c is also tapered relative to the second flow segment 10b, which serves as a confluence effect. The stepped structure between the second flow segment 10b and the third flow segment 10c can further slow down the flow, thereby improving the stability of the water outlet. Thus, from top to bottom, the first flow segment 10a, the second flow segment 10b, and the third flow segment 10c construct a progressive structure, with the flow segment cross-sectional area gradually decreasing. The two stepped structures can gradually slow down the water flow velocity during the flow process, improving the buffering effect on the water flow, so that the water flow at the outlet 102 can exit in a straight line. Especially when the high-temperature water flow rate is large, it can improve the water outlet effect for high-temperature water, thereby improving the stability of the water outlet and preventing scalding of users.

[0060] Combination Figure 4 In some embodiments of this utility model, the second housing 12 includes a first segment 121 and a second segment 122 connected in the vertical direction. The second housing 12 is provided with a plurality of first support plates 124, which extend vertically from the first segment 121 to the second segment 122, and are supported between the first housing 11 and the second housing 12. Specifically, the first support plate 124 of the first segment 121 can be supported between the inner wall of the first housing 11 and the first segment 121 of the second housing 12, thereby constructing a second flow channel 120, which helps to improve the stability of the water outlet device 100. The first support plate 124 of the second segment 122 can be supported between the first housing 11 and the second housing 12 in the horizontal or left-right direction, or vertically, thereby constructing a flow channel between the second flow channel 120 and the guide portion 20 (see...). Figure 6 In other words, the first support plate 124 can not only create a channel for the flow of water and gas, but also improve the structural stability of the assembly of the first shell 11 and the second shell 12.

[0061] 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 connection between the first section 121 and the second section 122. This can reduce the water flow velocity, help alleviate the impact force of the water flow, reduce pressure, improve the stability of the water flow, reduce eddies and turbulence, and ensure smooth water flow.

[0062] Combination Figure 6The flow area of ​​the first flow channel 110 gradually decreases in the direction near the outlet 102, while the flow area of ​​the second flow channel 120 gradually increases in the direction near the outlet 102. As a result, the flow velocity of the water from the first flow channel 110 and the second flow channel 120 at the outlet 102 is relatively small, making it easy for the water from the first flow channel 110 and the second flow channel 120 flowing out of the outlet 102 to merge together. After merging, the water outlet shape is round and stable, which can improve the user experience.

[0063] In some embodiments of this utility model, the second housing 12 further includes a third segment 123, the outer diameter of the second segment 122 is larger than the outer diameter of the third segment 123, and the flow guide 20 surrounds the third segment 123 and has a gap with the third segment 123. Thus, the third segment 123 can provide flow guide space for the flow guide 20, improving the water discharge effect of the water flowing out of the second flow channel 120.

[0064] In some embodiments of this utility model, the third segment 123 is constructed as a tube that gradually narrows from top to bottom, which is conducive to collecting water flow and improving the water output effect. Furthermore, the tubular outer wall of the third segment 123 can also cooperate with the guide portion 20 to achieve a guiding effect when the water output of the second flow channel 120 is large.

[0065] In some embodiments of the present invention, the water outlet device 100 further includes a third housing 13, an outlet 102 disposed within the third housing 13, a flow guide 20 disposed within the third housing 13, and the lower end of the first flow channel 110 disposed within the third housing 13; and / or the third housing 13 is integrally formed with the first housing 11.

[0066] In some embodiments of this utility model, the water outlet device 100 further includes a fourth housing 14, an inlet 101 is provided in the fourth housing 14, the lower part of the fourth housing 14 extends into the first flow channel 110, the lower end of the fourth housing 14 is closed, and a connecting hole 104 is provided on the lower periphery, the connecting hole 104 is connected to the first flow channel 110.

[0067] Combination Figure 1 and Figure 4 In some embodiments of the present invention, the fourth housing 14 covers the first housing 11. The fourth housing 14 is provided with a plurality of second support plates 142 arranged circumferentially. The lower ends of the plurality of second support plates 142 abut against the second housing 12. An overflow channel 130 connecting the first flow channel 110 and the second flow channel 120 is formed between the plurality of second support plates 142.

[0068] Specifically, the second housing 12 has an end plate that covers the upper end of the first housing. A water inlet pipe is located on the upper side of the end plate, and a buffer structure is constructed on the lower side of the end plate. The buffer structure is cylindrical, with its lower end closed. Multiple connecting holes 104 are spaced apart on its sidewalls. Water entering the inlet 101 from the water inlet pipe can flow slowly through the buffer structure and then be discharged circumferentially into the first flow channel 110. Multiple second support plates 142 are spaced circumferentially at the lower end of the end plate. These second support plates 142 are located on the upper part of the buffer structure cylinder and connect the lower end of the end plate to the sidewall of the buffer structure. The lower ends of the multiple second support plates 142 abut against the upper end of the second housing 12, and an overflow channel 130 connecting the first flow channel 110 and the second flow channel 120 is formed between the multiple second support plates 142.

[0069] Therefore, the overflow channel 130 can be close to the connecting hole 104, and the high-temperature gas of the high-temperature water can easily be discharged from the connecting hole 104 and directly enter the second flow channel 120 through the overflow channel 130. When the water flow rate is large, the water coming out of the connecting hole 104 can also easily overflow from the overflow channel 130 close to the connecting hole 104 into the second flow channel 120, thereby improving the diversion effect and flow slowing effect of the water outlet device 100.

[0070] In some embodiments of this utility model, the fourth housing 14 is integrally formed, which facilitates manufacturing and assembly and simplifies the structure of the water outlet device 100.
