[0049] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0050] The embodiments of the present application will be described below in conjunction with Figures 1 to 9 .

[0051] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 , according to the embodiments of the present application, on the one hand, a water outlet nozzle structure is disclosed, which comprises a water outlet seat provided with a water inlet hole 11 and a water outlet cavity 13 communicated with the water inlet hole 11, and the bottom of the water outlet seat is further provided with an exhaust passage and a water outlet structure, the exhaust passage is communicated with the water outlet cavity 13 and the outside, and the water outlet structure is communicated with the water outlet cavity 13.

[0052] The water outlet structure of the present application is as follows: water flows into the water outlet cavity 13 from the water inlet hole 11, and then flows out of the water outlet structure through the water outlet cavity 13 to be used by the user. On the one hand, the gas in the water in the water outlet cavity 13 can be discharged to the outside through the exhaust passage. On the other hand, negative pressure is easily formed in the water outlet cavity 13 during water outlet, and external gas can flow into the water outlet cavity 13 through the exhaust passage under the action of the negative pressure, so that the air pressure in the water outlet cavity 13 is balanced. By separating the water outlet and the exhaust, the water flow stability of the water outlet structure is ensured, and the water flow fluctuation, flow interruption or splitting caused by air intake / exhaust is avoided, so that the user experience is ensured.

[0053] It can be understood that when the water outlet cavity 13 is in negative pressure due to water outlet, external air will flow into the water outlet cavity 13 through the unobstructed exhaust passage; when the internal gas of the water outlet cavity 13 needs to be discharged, the internal gas will be discharged to the outside through the unobstructed exhaust passage, so as to avoid the influence of the gas on the water outlet through the water outlet structure, realize the separation of the water outlet and the exhaust, and ensure the stability of the water flow at the water outlet structure.

[0054] In some embodiments, the water outlet seat includes a first water outlet part 1 and a second water outlet part 2. The first water outlet part 1 has a water inlet hole 11 and a first exhaust hole 12. The bottom of the first exhaust hole 12 penetrates the first water outlet part 1, and the top of the first exhaust hole 12 communicates with the water outlet cavity 13. The second water outlet part 2 is arranged below the first water outlet part 1 and cooperates with the first water outlet part 1 to form the water outlet cavity 13. The second water outlet part 2 is provided with a water outlet structure and a second exhaust hole 23. The top of the second exhaust hole 23 penetrates the second water outlet part 2, and the top of the second exhaust hole 23 and the bottom of the first exhaust hole 12 correspondingly communicate to form an exhaust passage. The second exhaust hole 23 communicates with the outside.

[0055] During the water outlet process, the gas in the water in the water outlet cavity 13 can flow to the second exhaust hole 23 through the first exhaust hole 12 and be discharged to the outside. External gas can be sucked into the second exhaust hole 23 under the action of negative pressure, flow through the first exhaust hole 12, and then flow into the water outlet cavity 13, so that the air pressure in the water outlet cavity 13 is balanced, thereby ensuring the water flow stability of the water outlet structure.

[0056] Of course, the specific structure of the water outlet seat is not limited to the above form. For example, the water outlet seat can also be provided in an integrated structure, or the water outlet seat can be formed by splicing more parts.

[0057] The shape and size of the first water outlet part 1 match the shape and size of the second water outlet part 2. Specifically, the shape and size of the first water outlet part 1 and the second water outlet part 2 can be circular, oval or geometric. For example, the first water outlet part 1 and the second water outlet part 2 can be square, and the two cooperate to form a square water outlet cavity 13, but are not limited thereto.

[0058] As shown in FIG. 1, the water outlet seat 1 is provided with a water outlet cavity 13, and the water outlet cavity 13 is provided with a water outlet structure 2. The water outlet cavity 13 is provided with a water inlet hole 11 and a first exhaust hole 12. The bottom of the first exhaust hole 12 penetrates the first water outlet part 1, and the top of the first exhaust hole 12 communicates with the water outlet cavity 13. The second water outlet part 2 is arranged below the first water outlet part 1 and cooperates with the first water outlet part 1 to form the water outlet cavity 13. The second water outlet part 2 is provided with a water outlet structure and a second exhaust hole 23. The top of the second exhaust hole 23 penetrates the second water outlet part 2, and the top of the second exhaust hole 23 and the bottom of the first exhaust hole 12 correspondingly communicate to form an exhaust passage. The second exhaust hole 23 communicates with the outside. Figures 1 to 5As shown, in some embodiments, the water outlet structure further includes a top cover 3, which covers the opening at the top of the first water outlet 1. There is a flow gap between the top cover 3 and the top of the first vent hole 12, and the first vent hole 12 is connected to the water outlet cavity 13 through the flow gap.

[0059] The top cover 3 can seal the water outlet chamber 13 to ensure the water outlet chamber 13 is airtight and prevent impurities from entering the water outlet chamber 13 and polluting the water quality. The flow gap between the first vent hole 12 and the top of the top cover 3 can facilitate the connection between the first vent hole 12 and the water outlet chamber 13, which is conducive to the exhaust of the water outlet chamber 13 and the entry of external gas into the water outlet chamber 13.

[0060] In this embodiment, when the water outlet cavity 13 is set to be square, the top cover 3 is also set to be square and matches the size of the top opening of the first water outlet part 1 so as to better seal the water outlet cavity 13.

[0061] The first vent 12 extends vertically along the inside of the water outlet cavity 13. The top of the first vent 12 is set below the top edge of the water outlet cavity 13. When the top cover 3 is placed on the first water outlet 1, the top of the first vent 12 and the top cover 3 have a fitting gap so as to communicate with the water outlet cavity 13. The bottom of the first vent 12 is through and communicates with the second vent 23.

[0062] To improve exhaust efficiency, in this embodiment, two first exhaust holes 12 are provided in the water outlet cavity 13. The two first exhaust holes 12 are symmetrically arranged on the two side walls of the water outlet cavity 13, and a water flow channel is formed between the two first exhaust holes 12 to facilitate water flow to the water outlet structure.

[0063] Preferably, the two first vent holes 12 are located close to the outlet structure. Two second vent holes 23 are also provided, with each of the two second vent holes 23 corresponding to one of the two first vent holes 12. The water flow channels between the two second vent holes 23 and between the two first vent holes 12 are connected. The water flow channels are connected to the outlet structure and have a converging function, allowing the water in the outlet chamber 13 to flow towards the outlet structure after converging through the water flow channels, ensuring consistent water flow.

[0064] like Figure 5 , Figure 8 or Figure 9 As shown, in some embodiments, the water inlet 11 includes a hot water inlet 111, and the water outlet 13 is provided with a baffle 14. The baffle 14 and the hot water inlet 111 are correspondingly arranged. The bottom of the baffle 14 has a water passage gap. The hot water flowing into the hot water inlet 111 is impacted by the baffle 14 and flows from the water passage gap below the baffle 14 to the water outlet structure.

[0065] By setting the baffle 14 in the water outlet cavity 13, the hot water flowing into the hot water inlet hole 111 will first impact on the baffle 14 to achieve water-gas separation, wherein the hot water flows downward along the wall of the baffle 14, flows from the water gap below the baffle 14 to the water outlet structure, the separated gas flows upward, passes through the gap between the first exhaust hole 12 and the top cover 3, flows to the second exhaust hole 23, and flows out to the outside, achieving the exhaust of the water outlet cavity 13.

[0066] Specifically, the two ends of the baffle 14 are fixedly connected with the two side walls of the water outlet cavity 13 respectively, the bottom of the baffle 14 and the bottom wall of the water outlet cavity 13 have a water passing gap, and the top of the top plate and the top cover 3 have a gas passing gap, so that the gas in the water flow can flow through the first exhaust hole 12 and the second exhaust hole 23 through the gas passing gap and be exhausted.

[0067] Meanwhile, the water inlet hole 11 includes a normal temperature water inlet hole 112, and the setting position of the hot water inlet hole 111 is higher than that of the normal temperature water inlet hole 112. The normal temperature water flows into the water outlet cavity 13 through the normal temperature water inlet hole 112 and flows to the water outlet structure through the water gap. When the user takes hot water, the hot water flows into the water outlet cavity 13 from the hot water inlet hole 111, and when the user takes normal temperature water, the normal temperature water flows into the water outlet cavity 13 from the normal temperature water inlet hole 112.

[0068] As shown in FIGS. Figure 4 and Figure 5 In some embodiments, the water outlet structure includes a first water outlet hole 21 and a second water outlet hole 22, wherein the first water outlet hole 21 is in communication with the water outlet cavity 13, and the second water outlet hole 22 is arranged along the outer wall surface of the first water outlet hole 21. When the water outlet flow is less than a preset value, the water in the water outlet cavity 13 flows out through the first water outlet hole 21, and when the water outlet flow is greater than or equal to the preset value, part of the water in the water outlet cavity 13 flows out from the first water outlet hole 21 to the second water outlet hole 22, and the water flowing out of the second water outlet hole 22 flows along the outer wall surface of the first water outlet hole 21 and can flow together with the water flowing out of the first water outlet hole 21.

[0069] By setting the water outlet structure in the form of including the first water outlet hole 21 and the second water outlet hole 22, in the case that the water outlet flow is less than the preset value, that is, when the water outlet flow is small, the water in the water outlet cavity 13 can flow out in time through the first water outlet hole 21, and in the case that the water outlet flow is greater than or equal to the preset value, that is, when the water outlet flow is large, part of the water will overflow from the first water outlet hole 21 to the second water outlet hole 22 in the process of the water in the water outlet cavity 13 flowing out from the first water outlet hole 21, the second water outlet hole 22 shares the water outlet, and the water flowing out of the second water outlet hole 22 flows along the outer wall surface of the first water outlet hole 21 and can converge with the water flowing out of the first water outlet hole 21, thereby ensuring the consistency of the water flow at the end of the water outlet and reducing the splitting of the water flow.

[0070] And when hot water is taken, if the water flow fluctuates and splits, it is easy to cause the water flow to splash and scald the user, affecting the safety of the user taking water.

[0071] Preferably, the first water outlet hole 21 and the second water outlet hole 22 are arranged at the lowest position of the water outlet cavity 13, facilitating the water in the water outlet cavity 13 to flow out.

[0072] In the embodiment, the second water outlet hole 22 is provided with two and symmetrically arranged on both sides of the first water outlet hole 21, and the two second water outlet holes 22 can timely discharge the water overflowing from the first water outlet hole 21 when the water flow is large, ensuring the stability of the water flow of the first water outlet hole 21 and reducing the fluctuation of the water flow.

[0073] In other alternative embodiments, the number of the second water outlet hole 22 can also be set as needed, for example, three or four, etc.

[0074] As shown in the drawings, Figures 4 to 7 In some embodiments, the water outlet nozzle structure further includes a flow guide sleeve 4 arranged below the water outlet structure, and the flow guide sleeve 4 is sleeved on the first water outlet hole 21 and gap-fitted with the outer wall surface of the first water outlet hole 21.

[0075] The arrangement of the flow guide sleeve 4 can further guide and converge the water flowing out of the first water outlet hole 21, ensure the consistency of the water flow at the end of the water outlet, and avoid the splitting of the water flow.

[0076] As shown in the drawings, Figure 4 , Figure 6 and Figure 7 In some embodiments, the flow guide sleeve 4 is provided with a converging hole 41 and a buffer groove 42 in communication with the converging hole 41, wherein the flow guide sleeve 4 is sleeved on the first water outlet hole 21 through the converging hole 41, the inner wall of the converging hole 41 and the outer wall surface of the first water outlet hole 21 have a gap, the buffer groove 42 corresponds to the second water outlet hole 22, and the water of the second water outlet hole 22 can flow into the converging hole 41 through the buffer groove 42.

[0077] When the water flow is large, the water flowing out of the second water outlet hole 22 flows downward along the outer wall surface of the first water outlet hole 21, part of the water directly flows into the gap between the inner wall surface of the flow collecting hole 41 and the outer wall surface of the first water outlet hole 21, part of the water flows into the buffer groove 42 first, and then flows into the gap between the inner wall surface of the flow collecting hole 41 and the outer wall surface of the first water outlet hole 21 through the buffer groove 42, and finally flows together with the water flowing out of the first water outlet hole 21 to form a water flow, so that the buffer groove 42 can buffer the water flowing out of the second water outlet hole 22 when the water flow is large, and reduce the surging flow.

[0078] It can be understood that when the water flow is small, the water flowing out of the second water outlet hole 22 will not flow into the buffer groove 42, but will flow along the outer wall surface of the first water outlet hole 21 and then flow together with the water flowing out of the first water outlet hole 21 to form a water flow.

[0079] In the embodiment, the buffer groove 42 is provided with two buffer grooves which are symmetrically arranged on both sides of the flow collecting hole 41, and the two buffer grooves 42 and the two second water outlet holes 22 are one-to-one corresponding. In other embodiments, the number of buffer grooves 42 is adjusted according to the number of second water outlet holes 22, and is not limited to the embodiment.

[0081] In some embodiments, the flow guide sleeve 4 is further provided with a third exhaust hole 43 which is in communication with the outside, and the third exhaust hole 43 and the second exhaust hole 23 are in communication.

[0082] By providing the third exhaust hole 43 on the flow guide sleeve 4, the gas in the water outlet cavity 13 is sequentially discharged to the outside through the first exhaust hole 12, the second exhaust hole 23 and the third exhaust hole 43, realizing water outlet and gas discharge, and at the same time, the external gas flows into the water outlet cavity 13 through the third exhaust hole 43, the second exhaust hole 23 and the first exhaust hole 12 in sequence, realizing dynamic balance of internal and external air pressure.

[0083] One end of the second exhaust hole 23 extends towards the water outlet cavity 13 to facilitate communication with the first exhaust hole 12, the other end of the second exhaust hole 23 extends towards the water outlet structure, and the bottom of the second exhaust hole 23 is penetrated and in communication with the third exhaust hole 43.

[0084] In the embodiment, the third exhaust hole 43 is provided with two third exhaust holes which are symmetrically arranged, and the two third exhaust holes 43 and the two second exhaust holes 23 are one-to-one corresponding to improve the exhaust efficiency. In other embodiments, the number of third exhaust holes 43 is adjusted according to the number of second exhaust holes 23, and is not limited to the embodiment.

[0085] The third exhaust hole 43 is shaped to match the shape of the second exhaust hole 23.

[0086] In some embodiments, the guide sleeve 4 and the second water outlet portion 2 are fixedly installed through the guide connecting structure.
