DETAILED DESCRIPTION

[0032] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0033] COMBINATION Figures 1 to 3The water outlet device 100 of the water drinking equipment 1000 according to the embodiment of the present application comprises a shell having 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 communicated with the inlet 101 and the lower end is communicated with the outlet 102, and the upper end of the second flow channel 120 is communicated with the upper end of the first flow channel 110 and the lower end is communicated with the outlet 102.

[0034] Specifically, the upper end of the first flow channel 110 is connected with the inlet 101 and the lower end is connected with 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 of the outlet 102, realizing the water outlet function of the water outlet device 100. Further, when the water outlet device 100 outputs high-temperature hot water or boiling water, water vapor is accompanied during the water outlet process, and 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 water outlet interruption, floating and scattering, etc. The irregular water outlet trajectory of hot water and the mixing of water vapor are easy to scald the user, and there is a safety hazard. Therefore, when the water outlet device 100 outputs high-temperature hot water or boiling water, after the hot water enters the shell from the inlet 101, the water can flow downward from the first flow channel 110 and flow out of the outlet 102, so that the hot water flow out of the first flow channel 110 is stable, and the water outlet form is round. The water vapor can flow upward to the second flow channel 120 connected with 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 on the one hand to provide an air flow path, and on the other hand can prolong the flow path of high-temperature gas flow or water vapor, reducing the risk of high-temperature gas flow injury.

[0035] Further, in combination with Figure 2, the water outlet device 100 further comprises a flow guide part 20 extending in the up-down direction and connected to the lower end of the second flow channel 120, and the peripheral wall of the flow guide part 20 is provided with a hollow structure 201, which can improve the water outlet stability. Specifically, when the water outlet flow is large, part of the water entering the inlet 101 flows out from the first flow channel 110. Due to the large water flow, 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 have a buffering effect, can slow down the water flow impact force, and can moderate the water flow. When the water flows to the lower end of the second flow channel 120, the flow guide part 20 can guide the water flow to flow downward, improve the water outlet stability and the water shape of the water outlet, and improve the water outlet stability. At the same time, the hollow structure 201 of the flow guide part 20 can make the second flow channel 120 communicate with the atmosphere, so that the large-flow water can be uniformly collected in the second flow channel 120, prevent the formation of water film, cause the formation of negative pressure in the water outlet device 100, and accumulate the remaining water in the cavity, thereby improving the water outlet stability and water outlet effect when large-flow water is outlet.

[0036] According to the water outlet device 100 of the water drinking equipment 1000 of the embodiment of the present application, by arranging the second flow channel 120 communicating with the first flow channel 110, the water vapor separation effect can be realized when high-temperature water is outlet, thereby improving the water outlet stability; when large-flow low-temperature water is outlet, the 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 can simultaneously outlet water, and the flow guide part 20 arranged at the lower end of the second flow channel 120 can guide the water flow, and the hollow structure 201 arranged at the lower end of the flow guide part 20 can communicate with the atmosphere, thereby preventing the formation of negative pressure in the water outlet device 100 and improving the water outlet effect.

[0037] It should be noted that the water outlet device 100 can outlet low-flow high-temperature water. Due to the low water outlet flow, the high-temperature water can completely flow out 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 outlet large-flow low-temperature water. At this time, part of the water directly flows out from the first flow channel 110 after entering the first flow channel 110, and part of the water overflows to the second flow channel 120 and flows out from the second flow channel 120. The flow guide part 20 at the lower end of the second flow channel 120 can be used to guide the water flow and improve the water outlet stability, and the hollow structure 201 of the flow guide part 20 can also have the effect of balancing the air pressure inside and outside the water outlet device 100, thereby improving the water outlet smoothness. In addition, the water outlet device 100 can outlet large-flow high-temperature water. At this time, 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 to 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 guided to flow out by the flow guide part.

[0038] In combination with Figure 3In some embodiments of the present application, the second flow channel 120 is arranged around the first flow channel 110, which can improve the flow effect of water or high-temperature steam 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 steam can also enter the second flow channel 120 in the circumferential direction, which is beneficial to improve the water or steam inflow and uniformity.

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

[0040] In combination Figure 3 And Figure 6 In some embodiments of the present application, the shell includes a first shell 11 and a second shell 12, the first shell 11 is arranged around the outside of the second shell 12, the first flow channel 110 is arranged in the second shell 12, and the second flow channel 120 is arranged between the first shell 11 and the second shell 12. For example, the first flow channel 110 and the second flow channel 120 are coaxially arranged, and the second flow channel 120 is arranged outside the first flow channel 110. In this way, the water or steam of the first flow channel 110 can flow to the second flow channel 120 in the circumferential direction, which is beneficial to improve the flow and the uniformity of the flow, thereby improving the water outlet and the gas outlet effect, and also improving the compactness of the structure, which is beneficial to realize the miniaturization of the water outlet device 100.

[0041] In some embodiments of the present application, the upper periphery of the flow guide part 20 is connected to the lower periphery of the first shell 11, which is convenient for arranging the flow guide part 20. In application, the water or steam discharged from the second flow channel 120 can be discharged from the second flow channel 120 through the flow guide part 20, which is beneficial to improve the water outlet effect.

[0042] In some embodiments of the present application, the flow guide part 20 surrounds the lower end of the second shell 12 and is inclined inward in the downward extending direction, which can guide the water flowing out of the second flow channel 120 to flow towards the outlet 102 of the first flow channel 110. When the user receives water, the water outlets of the first flow channel 110 and the second flow channel 120 can be collected together and flow out of the outlet 102, which is beneficial to improve the water outlet effect. In addition, the lower periphery of the flow guide part 20 and the lower end of the second shell 12 have a gap, which can provide a certain water outlet space for the second flow channel 120, so as to avoid the water of the second flow channel 120 mixing into the water flow of the first flow channel 110, but gradually converging with the first flow channel 110 at the outlet 102, so that the water outlet form is smooth and stable, without flow interruption or shaking.

[0043] In some embodiments of the present application, the flow guide part 20 is inclined inward in the downward extending direction, which can guide the water flow inward to converge with the water flow of the first flow channel 110, thereby improving the water outlet effect.

[0044] In some embodiments of the present application, the hollow structure 201 is distributed along the circumference of the flow 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 also avoid water from being squeezed in the flow channel, thereby improving the water outlet effect.

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

[0046] In some embodiments of the present application, the flow guide rib 21 is configured in a form of gradually decreasing width from top to bottom, which can guide water flow, facilitate the improvement of the flow guiding effect, and improve the fluid flow state, thereby improving the water flow out shape.

[0047] In some embodiments of the present application, the flow guide portion 20 includes a reinforcing rib 22, and the reinforcing rib 22 connects the plurality of flow guide ribs 21. The reinforcing rib 22 can connect the plurality of flow guide ribs 21 extending in the up-down direction, thereby improving the structural strength and stability of the flow guide portion 20. When the flow guide portion 20 is impacted by water flow, the reinforcing rib 22 can disperse the force. Specifically, in combination Figure 3 The reinforcing rib 22 is connected to the middle part of the flow guide rib 21 in the up-down direction. The plurality of flow guide ribs 21 and the reinforcing rib 22 are integrally formed.

[0048] In some embodiments of the present application, in combination Figure 2 The shell further includes a third shell 13, the outlet 102 is arranged in the third shell 13, the flow guide portion 20 is arranged in the third shell 13, and the lower end of the first flow channel 110 is arranged in the third shell 13. The third shell 13 can shield the outlet 102 and the flow guide portion 20, so that the water flowing out of the first flow channel 110 and the water or gas flowing out of the flow guide portion 20 can be in the third shell 13, thereby preventing water from splashing or gas from diffusing, facilitating the collection of water, and improving the water outlet effect.

[0049] In combination Figure 4 And Figure 6In some embodiments of the present application, the shell further comprises a fourth shell 14, the inlet 101 is arranged on the fourth shell 14, the lower part of the fourth shell 14 extends into the first flow channel 110, the lower end of the fourth shell 14 is closed, and the lower periphery is provided with a communication hole 104 which is in communication with the first flow channel 110. Specifically, water can enter from the inlet 101 of the fourth shell 14, and then flow into the first flow channel 110 from the communication hole 104 on the lower periphery. Since the lower end of the fourth shell 14 is closed, the effect of moderating the impact force of the water flow can be achieved. The communication hole 104 is arranged in multiple along the lower periphery. When the water flow flows out from the multiple communication holes 104, the effect of slowing down the flow can be achieved, so that the flow rate of the water entering the first flow channel 110 is relatively stable, and then flows out from the first flow channel 110.

[0050] When the high-temperature water enters the fourth shell 14, the flow rate of the high-temperature water flowing out from the communication hole 104 can be slowed down, which is beneficial for water-vapor separation. When the steam is discharged from the communication hole 104, it can enter the second flow channel 120. Thus, the high-temperature water flowing out from the communication hole 104 enters the first flow channel 110, and the high-temperature vapor body moves upward after entering the first flow channel 110, and can enter the second flow channel 120 connected to the upper end of the first flow channel 110, and then flows out from the second flow channel 120. When the water inflow is large, a large amount of water enters the fourth shell 14 from the inlet 101, and the impact force of the water with large flow rate is large. The closed structure of the lower end of the fourth shell 14 and the communication hole 104 on the periphery can form a buffer structure. When the water with large flow rate enters the first flow channel 110 through the buffer structure, the water can be slowed down once, 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, and the water can be slowed down again, so that the impact force of the water flow can be further slowed down. The water in the first flow channel 110 and the second flow channel 120 converges at the outlet 102, so that the stability and uniformity of the water when flowing out can be improved.

[0051] In some embodiments of the present application, in combination with Figure 4 and Figure 6 , the communication hole 104 is arranged in a grid shape, so that the uniformity of the water flowing out can be improved, and the effect of slowing down the impact force of the water flow can be improved. Specifically, when the water flow enters the first flow channel 110 from the fourth shell 14, the water flow is blocked by the closed end and the peripheral wall of the fourth shell 14, so that the effect of slowing down the water flow can be achieved. The flow rate of the water flowing out from the communication hole 104 is relatively stable, and the communication effect of the fourth shell 14 and the first flow channel 110 can be improved.

[0052] In combination with Figure 6 , the lower end periphery of the fourth shell 14 and the closed end of the lower end are arc-shaped, so that the effect of guiding the flow can be achieved, and the fourth shell 14 is easy to be formed and manufactured.

[0053] In some embodiments of the present application, in combination with Figure 4The lower end of the fourth shell 14 is provided with a flow guide plate, and the closed end is arranged on the inner side of the flow guide plate.

[0054] In combination Figure 6 In some embodiments of the present application, the first flow channel 110 includes a first flow section 10a and a second flow section 10b which are communicated along the up-down direction, and the inner diameter of the second flow section 10b is smaller than that of the first flow section 10a. That is, the inner diameter of the upper part of the first flow channel 110 is larger than that of the lower part, and the flow channel of the first flow channel 110 is narrowed in the water flow process, which can play a converging effect. A step structure is formed between the first flow section 10a and the second flow section 10b, and when the water flow flows to the step structure, the step structure can play a slow flow effect, which can reduce the water flow pulsation and improve the water outlet effect. Or in the first flow channel 110, the flow channel is gradually contracted from top to bottom.

[0055] The lower part of the fourth shell 14 is located at the upper part of the first flow section 10a, so that the water flow can continue to flow in the first flow channel 110 for a distance after flowing out of the communication hole 104, which is beneficial to the water flow stability when the water flow flows to the outlet 102. The lower part of the fourth shell 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 shell 14 is large, and the increase of the space of the first flow section 10a is beneficial to improve the water flow space, thereby increasing the water outlet amount.

[0056] Specifically, the lower part of the fourth shell 14 located at the upper part of the first flow section 10a can be located at the flow section of 1 / 2 or more than 1 / 2 of the length dimension of the first flow section 10a along the up-down direction; or can be located at the flow section of 2 / 3 or more than 2 / 3 of the length dimension of the first flow section 10a along the up-down direction, etc. In summary, the lower part of the fourth shell 14 and the lower end of the first flow section 10a have a certain interval, which is beneficial to prolong the water flow path.

[0057] Further, in combination Figure 6In some embodiments of the present application, the first flow channel 110 includes a third flow section 10c connected to the second flow section 10b in the up-down direction, a step structure is formed between the third flow section 10c and the second flow section 10b, and the inner diameter of the third flow section 10c is smaller than the inner diameter of the second flow section 10b. That is, the third flow section 10c is also in the form of tapering with respect to the second flow section 10b, and plays a role of converging flow. The step structure between the second flow section 10b and the third flow section 10c can further play a role of slowing down flow, thereby improving the outflow stability. In this way, from top to bottom, the first flow section 10a, the second flow section 10b and the third flow section 10c form a progressive structure, the cross-sectional area of the flow section gradually decreases, and the two step structures can gradually slow down the flow velocity of the water flow in the flow process, improve the buffering effect of the water flow, and make the water flow at the outlet 102 flow along a straight line. Especially when the high-temperature water flow is large, the outflow effect of the high-temperature water can be improved, thereby improving the outflow stability and avoiding scalding the user.

[0058] In combination Figure 4 In some embodiments of the present application, the second shell 12 includes a first section 121 and a second section 122 connected in the up-down direction, the second shell 12 is provided with a plurality of first support plates 124 extending 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 plates 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, thereby forming the second flow channel 120 and improving the stability of the water outlet device 100. The first support plates 124 of the second section 122 can be supported between the first shell 11 and the second shell 12 in the transverse or left-right direction, or in the up-down direction, thereby forming flow channels between the second flow channel 120 and the flow guide part 20 (see Figure 6 ) between the plurality of first support plates 124. That is, the first support plates 124 can form a flow passage for water and steam, and can also improve the structural stability of the assembly of the first shell 11 and the second shell 12.

[0059] Further, the second shell 12 is in the form of a cylinder, the outer diameter of the second section 122 is smaller than the outer diameter of the first section 121, thereby the flow channel of the second flow channel 120 near the outlet 102 at the lower end of the second flow channel 120, or the flow channel of the second flow channel 120 at the position where the first section 121 and the second section 122 are connected, can be enlarged, which can slow down the flow velocity of the water flow, help to relieve the impact force of the water flow, facilitate to reduce the pressure, improve the stability of the water flow, reduce the vortex and turbulence, and ensure smooth flow.

[0060] In combination Figure 6, the first flow channel 110 gradually decreases in flow area in the direction close to the outlet 102, and the second flow channel 120 gradually increases in flow area in the direction close to the outlet 102, so that the flow rates of the water from the first flow channel 110 and the second flow channel 120 at the outlet 102 are small, the water from the first flow channel 110 and the second flow channel 120 at the outlet 102 is easy to converge, and the water after convergence is stable, which can improve the user experience.

[0061] In some embodiments of the present application, the second shell 12 further comprises 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 part 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 part 20, and improve the water outlet effect of the water flowing out of the second flow channel 120.
