In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] like Figure 1-Figure 3 As shown, this embodiment provides an anti-turbulence water nozzle, which includes a cavity shell 1 and a damping drainage net 2. The cavity shell 1 has a buffer cavity 10, and the shell wall of the cavity shell 1 is provided with a hot water inlet 11 and a confluence outlet 13. The damping drainage net 2 is arranged in the buffer cavity 10, and the damping drainage net 2 is opposite to the hot water inlet 11 and arranged at intervals. The damping drainage net 2 extends from top to bottom, and the lower end is connected to the inner wall of the buffer cavity 10, so that the hot water flowing onto the damping drainage net 2 flows to the inner wall of the buffer cavity 10 along the extension direction of the damping drainage net 2.

[0035] When the anti-turbulence water nozzle is working, when hot water enters the buffer chamber 10 from the hot water inlet 11, part of the hot water passes through the damping drainage net 2. Due to the resistance, the hot water that passes through the damping drainage net 2 flows downward along the surface of one side of the damping drainage net 2, and the hot water that does not pass through the damping drainage net 2 flows downward on the other surface of the damping drainage net 2. The hot water flowing downward is affected by the multiple mesh holes on the damping drainage net 2, and the bubbles in the hot water are significantly eliminated, thereby greatly improving the water flow shape of the outlet water, making the outlet water shape of the heated water flow stable. After the hot water flows to the inner wall of the buffer chamber 10 in a gentle manner, it flows out from the confluence outlet 13, which is also conducive to the elimination of bubbles.

[0036] In this embodiment, the mesh size of the damping drainage net 2 is determined according to parameters such as the flow rate and temperature of the hot water to achieve the function of damping drainage. Exemplarily, the damping drainage net 2 is a metal net.

[0037] like Figure 2 and Figure 3As shown, optionally, a cold water inlet 12 is further provided on the shell wall of the cavity shell 1, and the hot water inlet 11 and the cold water inlet 12 are both located on the side wall of the cavity shell 1, the hot water inlet 11 is higher than the cold water inlet 12, and the lower end of the damping drainage net 2 is connected to the edge of the cold water inlet 12. The damping drainage net 2 drains the hot water to the cold water inlet 12, so that the hot water and the cold water in the cold water inlet 12 merge, and at the beginning of the merging of the hot water and the cold water, the meshes on the damping drainage net 2 can continue to play the role of eliminating bubbles, eliminating bubbles formed by the excessive temperature difference between the hot water and the cold water.

[0038] like Figure 2 and Figure 3 As shown, the anti-turbulence water nozzle also includes a buffer net 3, which covers the confluence outlet 13 and is attached to the shell wall of the cavity shell 1. The buffer net 3 is used for the confluence of cold water and hot water to pass through, eliminate the slight flow fluctuations of the water flow, and make the water flow gather to a certain extent, so that the water flow is stable and continuous when it flows out of the confluence outlet 13, that is, improves the water type. In this embodiment, the mesh size of the buffer net 3 is determined according to parameters such as the flow rate and temperature after the hot water and cold water are mixed, so as to improve the water type. Exemplarily, the buffer net 3 is a metal net.

[0039] like Figure 2 and 3 As shown, optionally, the hot water inlet 11 is located at the upper end of the side wall of the cavity shell 1, and the cold water inlet 12 is located at the lower end of the side wall of the cavity shell 1, and the hot water inlet 11 is located directly above the cold water inlet 12. The hot water inlet 11 and the cold water inlet 12 are vertically distributed at the upper and lower ends of the side wall of the cavity shell 1, which is conducive to increasing the flow stroke of hot water on the damping drainage net 2, thereby improving the effect of eliminating bubbles. The hot water inlet 11 is located directly above the cold water inlet 12, which is convenient for draining hot water to the cold water inlet 12 by gravity, ensuring the stability of the flow direction.

[0040] like Figure 2 and Figure 3 As shown, optionally, the confluence outlet 13 is provided on the bottom wall of the chamber shell 1 and is located at one end of the bottom wall in the horizontal direction away from the cold water inlet 12, and the bottom wall of the chamber shell 1 gradually decreases along the direction from the cold water inlet 12 to the confluence outlet 13. After the hot water and the cold water converge at the cold water inlet, they flow to the confluence outlet 13 along the bottom wall of the chamber shell 1 under the action of gravity. The confluence outlet 13 is located at one end of the bottom wall in the horizontal direction away from the cold water inlet 12. The confluenced water flows to the confluence outlet 13 after a longer journey, which is conducive to improving the stability of the water flow.

[0041] like Figure 2 and Figure 3As shown, optionally, the anti-turbulence water nozzle also includes a water guiding shell 4 and an anti-overflow pipe 5, the water guiding shell 4 is connected to the outside of the cavity shell 1, and is provided with a first inlet 44, a second inlet 46 and a water outlet 47. The first inlet 44 is correspondingly connected to the confluence outlet 13, the upper end of the anti-overflow pipe 5 is located in the buffer cavity 10, and is higher than the cold water inlet 12 and the confluence outlet 13, the lower end of the anti-overflow pipe 5 extends downward through the bottom wall of the cavity shell 1 to be connected with the second inlet 46, and the anti-overflow pipe 5 is located between the cold water inlet 12 and the confluence outlet 13 in the horizontal direction.

[0042] That is to say, the confluence in the buffer chamber 10 enters the water-guiding housing 4 from the first inlet 44 and finally flows out from the water outlet 47. On the other hand, when there is too much fluid in the buffer chamber 10, the confluence overflows into the anti-overflow pipe 5, flows through the second inlet 46 into the water-guiding housing 4, and finally flows out from the water outlet 47, thereby avoiding the pressure buildup in the chamber shell 1 due to the significant increase in the water inlet of the hot water inlet 11 and the cold water inlet 12, thereby avoiding affecting the water pressure of the confluence outlet 13 and improving the stability of the water flow. The anti-overflow pipe 5 is located between the cold water inlet 12 and the confluence outlet 13 in the horizontal direction, which is conducive to increasing the flow stroke and improving the buffering effect of the buffer chamber 10.

[0043] Optionally, the anti-turbulence water nozzle further includes a water baffle 6, which is arranged on the side of the overflow prevention pipe 5 facing the hot water inlet 11, and the water baffle 6 extends upward from the overflow prevention pipe 5 to be higher than the hot water inlet 11. The water baffle 6 is used to install and support the damping drainage net 2, and can prevent the water of the hot water inlet 11 from directly entering the overflow prevention pipe 5.

[0044] Optionally, the water-conducting housing 4 includes an inner tube portion 41 and an outer tube portion 42, the outer tube portion 42 is sleeved outside the inner tube portion 41 at intervals to form an overflow channel 45 between the inner tube portion 41 and the outer tube portion 42, the upper end of the inner tube portion 41 is a first inlet 44, the first inlet 44 is connected to the confluence outlet 13, the lower end of the inner tube portion 41 and the lower end of the overflow channel 45 around it jointly form a water outlet 47, and the upper end of the overflow channel 45 is a second inlet 46. The inner and outer arrangements of the inner tube portion 41 and the outer tube portion 42 allow the overflowing fluid and the fluid from the confluence outlet 13 to flow out from the water outlet 47, making it convenient for users to receive water.

[0045] Optionally, the water guide housing 4 further includes a guide portion 43, the upper end of the guide portion 43 is connected to the bottom wall of the chamber housing 1, and the lower end is connected to the outer tube portion 42 to communicate with the second inlet 46, and the lower end of the overflow prevention pipe 5 is located directly above the guide portion 43. The guide portion 43 is used to receive the fluid flowing out of the overflow prevention pipe 5 and guide it to the overflow channel 45.

[0046] This embodiment also provides a quick-heating water dispenser, which includes a water supply body and the above-mentioned anti-turbulence water nozzle, wherein the hot water inlet 11 of the anti-turbulence water nozzle is connected to the hot water outlet of the water supply body. The quick-heating water dispenser uses the above-mentioned anti-turbulence water nozzle to output hot water with stable water type.
