Description

Technical Field

[0001] This utility model relates to a water outlet valve device, specifically a water outlet device that causes water to flow out in a concentrated stream. Background Technology

[0002] Water dispensers, tea bars, and other similar appliances require their nozzles to deliver a continuous, focused stream of water regardless of flow rate, providing users with a smooth and consistent flow. Patent CN202320985936.9 proposes a diverting and focusing water nozzle and module, whose structure can focus the water flow from the main and secondary drain holes regardless of the inflow volume. However, because the main drain hole is not centered on the peripheral secondary drain holes, when using a nozzle with this structure, the liquid flow falling and converging through the secondary drain holes is misaligned with the liquid flow in the main drain hole, failing to completely converge into a single stream, resulting in some water droplets splashing. In addition, when the water pressure in the inlet pipe of the water outlet module is high, the water flow will directly bypass the diversion plate between the main channel and the secondary channel and directly spray into the water accumulation chamber of the secondary outlet hole, flowing out of the water outlet hole before the main outlet hole. At this time, multiple water flows will be discharged at the same time and cannot be gathered into a bundle at the center, which will also cause water splashing. Utility Model Content

The upper end of the diversion plate leaves a gap with the top wall of the water collection cavity of the water outlet box, and the main channel and the secondary channel are interconnected in the upper part of the water collection cavity.

[0016] Specific Implementation Example 1: Please refer to the appendix Figure 1 -Appendix Figure 8 , A water outlet device for concentrating water flow includes a water outlet 1, a water outlet box 2, and a box cover 3.

[0017] The water outlet box 2 has a hollow water collection cavity inside, with the upper side of the water collection cavity extending through the upper part of the water outlet box 2, forming a semi-open structure. The bottom wall of the water collection cavity of the water outlet box 2 is inclined to one side, and the water outlet 1 penetrates through the lower end of the bottom wall of the water outlet box 2 and is detachably connected and fixed to the water outlet box 2. The box cover 3 is detachably installed on the upper end of the water outlet box 2 to close the upper opening of the water collection cavity.

[0018] The water collection chamber of the water outlet box 2 has a vertically extending diversion plate 13 near the lower end, and the diversion plate 13 is fixedly connected to the inner wall of the water outlet box 2. Figure 2 As shown, the middle of the diversion plate 13 forms a protruding U-shaped bend towards the lower end of the water accumulation chamber, and the diversion plate 13 at the bend is separated from the inner wall of the water outlet box 2. Figure 3 and Figure 4 As shown, the bottom of the diverter plate 13 at the curved and recessed section is fixedly connected to a horizontal wall, which is higher than the lowest point of the bottom wall of the water collection chamber of the water outlet box 2. A recessed cavity is formed between the horizontal wall of the curved and recessed section of the diverter plate 13 and the lowest point of the water collection chamber of the water outlet box 2. The diverter plate 13 divides the bottom of the water collection chamber of the water outlet box 2 into two independent parts, forming a main flow channel and a secondary flow channel. The main flow channel includes the part above the horizontal wall of the bottom of the curved and recessed side of the diverter plate 13, and the bottom space of the water collection chamber from the curved and recessed side of the diverter plate 13 to the highest point of the bottom wall of the water outlet box 2. The secondary flow channel includes the recessed cavity formed between the horizontal wall of the curved and recessed section of the diverter plate 13 and the lowest point of the water collection chamber, and the bottom space of the water collection chamber from the curved and protruding side of the diverter plate 13 to the lowest point of the bottom wall of the water outlet box 2. The upper end of the diverter plate 13 is separated from the cover 3 above the water outlet box 2, and the main flow channel and the secondary flow channel are interconnected in the upper part of the water collection chamber. The main flow channel is used to receive the water that needs to be discharged from the water accumulation chamber, and the secondary flow channel is used to receive the portion of the water in the main flow channel that overflows from the top of the diversion plate 13.

[0019] The water outlet 1 has a vertically extending main drain hole 11 and secondary drain holes 12. The main drain hole 11 is located at the center of the water outlet 1, and its inlet extends upward to form a protruding neck 111. Four secondary drain holes 12 are evenly spaced around the main drain hole 11, with adjacent secondary drain holes 12 separated by supporting ribs. The neck 111 above the main drain hole 11 abuts against the bottom horizontal wall of the curved recessed part of the diversion plate 13. A through hole is provided on the bottom horizontal wall of the curved recessed part of the diversion plate 13, corresponding to the main drain hole 11 at the center of the neck 111, thus connecting the main drain hole 11 with the main flow channel. The peripheral space of the neck 111 is above the secondary drain holes 12, corresponding to the valley cavity formed between the horizontal wall of the curved recessed part of the diversion plate 13 and the lowest point of the water accumulation chamber, thus connecting the secondary drain holes 12 with the secondary flow channel.

[0020] The lower part of the water outlet 1 is conical. The outlet of the main drain hole 11 is located at the center of the conical end of the water outlet 1. The outlets of the four secondary drain holes 12 are located on the conical surface of the water outlet 1, and are arranged in a ring around the outlet of the main drain hole 11, with uniform spacing between them. The height of the outlet of the secondary drain hole 12 is higher than the height of the outlet of the main drain hole 11, and the outlets of the secondary drain holes 12 and the outlets of the main drain holes 11 are connected by a conical surface.

[0021] Water flow convergence principle: The water flowing out of the secondary outlet 12 will converge towards the conical end of the outlet 1 under the guidance of the conical surface. The water flows from the four secondary outlets 12 converge at one point, and the converged water flow coincides with the water flow of the main outlet 11 located at the center of the conical end, and together they converge into a single water flow.

[0022] Preferred, such as Figure 8 As shown, each secondary row of holes 12 has a flow guiding rib 121 as a flow guiding structure. The four flow guiding ribs 121 are arranged around the main row of holes 11, with a uniform spacing between them. Each flow guiding rib 121 is located on the wall surface of the secondary row of holes 12 on the side closest to the main row of holes 11, and the side wall of the flow guiding rib 121 is separated from the other holes of the secondary row of holes 12. The flow guide 121 is vertically arranged and extends from the inlet end of the secondary drain hole 12 to the outlet end of the secondary drain hole 12. The flow guide 121 forms a gradually inclined flow slope 1211 near the outlet end of the secondary drain hole 12, which is close to the side of the main drain hole 11. The flow slope 1211 is located above the conical surface connecting the outlet of the secondary drain hole 12 to the outlet of the main drain hole 11. By utilizing the wall effect, the water flow in the secondary drain hole 12 is guided from the inner wall surface of the secondary drain hole 12 to the conical surface. Finally, under the guidance of the conical surface, it flows to the outlet of the main drain hole 11 until it converges with the water flow in the main drain hole 11, preventing the water flow from flowing to the outer wall surface of the secondary drain hole 12 and splashing during the falling process.

[0023] Two water inlet pipes 14 are horizontally installed on the high end side of the bottom wall of the water outlet box 2, penetrating the side wall of the water outlet box 2. The two water inlet pipes 14 are arranged horizontally side by side on the upper part of the side wall of the water outlet box, and are used to allow water from an external water source to flow into the water outlet box 2.

[0024] Preferred, such as Figure 6 As shown, on the lower surface of the cover 3, near the side where the water inlet pipe 14 is located in the water outlet box 2, a water-blocking and flow-retarding plate 21 extends downwards. The water-blocking and flow-retarding plate 21 correspondingly and intermittently blocks the outlet of the water inlet pipe 14 located within the water accumulation chamber. The water-blocking and flow-retarding plate 21 is positioned horizontally between the diversion plate 13 and the outlet of the water inlet pipe 14 to prevent excessive water pressure in the water inlet pipe 14 from causing water to directly spray over the diversion plate 13 and enter the secondary flow channel, resulting in the secondary outlet 12 discharging water before the main outlet 11. Figure 4 As shown, the lower end of the water-blocking and flow-slowing plate 21 is not higher than the upper end of the flow-dividing plate 13, forming a bend blocked by the water-blocking and flow-slowing plate 21. The overflow of water in the main channel is restricted by the water-blocking and flow-slowing plate 21 and will overflow into the secondary channel in a relatively stable and gentle manner to help the water flow at the outlet of the secondary discharge hole 12 and the water flow at the outlet of the main discharge hole 11 converge and merge.

[0025] On one side of the high end of the bottom wall of the water outlet box 2, there is a vent pipe 22 that extends upward through the bottom wall. The vent pipe 22 is on the side facing away from the water inlet pipe 14 at the top, so that the water accumulation chamber of the water outlet box 2 can be connected with the outside atmosphere to ensure the air pressure balance inside the water accumulation chamber when water is discharged.

[0026] Preferred, such as Figure 4 As shown, the lowest point of the upper lateral opening of the vent pipe 22 is not lower than the maximum height of the water inlet pipe 14, so as to prevent water from entering the vent pipe 22.

[0027] Preferably, the lower surface of the cover 3 is provided with a vertically extending guide column 31. The guide column 31 is located directly above the main drain hole 11 of the water outlet 1. When the water level in the water accumulation chamber drops and the state of water flowing out of the main drain hole 11 and the secondary drain hole 12 after overflow changes to the state of water flowing out of only the main drain hole 11, the water flow attached to the wall at the top of the water outlet box 2 will be guided down to the main drain hole 11 directly below.

[0028] Preferably, the entire water outlet box 2 is made of hydrophobic PP material so that residual water droplets on the walls of the main and secondary channels in the water accumulation chamber can fall and be discharged, reducing the phenomenon of intermittent dripping of water outlet 1 after drainage.

[0029] Preferably, the lower conical surface of the water outlet 1 and the surface of the inner guide rib 121 of the secondary drain hole 12 are made of hydrophilic material PA to enhance the wall adhesion effect of the water flow, so as to help the water flow at the outlet of the secondary drain hole 12 and the water flow at the outlet of the main drain hole 11 converge.

[0030] Drainage diversion principle: such as Figure 5 As shown, when water is injected into the water collection chamber through the inlet pipe 14, the water first flows along the inclined bottom wall of the water collection chamber in the main channel, and finally flows out through the main outlet hole 11; Figure 6 As shown, after water is continuously introduced into the main channel of the water accumulation chamber, not all the water can be discharged through the main drain hole 11. The water accumulates in the main channel, and the liquid level in the main channel gradually rises. When the liquid level in the main channel continues to rise until it is higher than the upper edge of the diversion plate 13 and overflows, the overflowing water will enter the secondary channel. The water flows along the secondary channel to the peripheral space of the neck 111, that is, the concave cavity formed between the horizontal wall of the curved and concave part of the diversion plate 13 and the lowest point of the water accumulation chamber. Finally, it flows into the secondary drain hole 12 and is discharged. According to the above-mentioned confluence principle, the water flow is combined with the water flow of the main drain hole 11.

[0031] The above description is only a preferred embodiment of the present utility model and is intended to illustrate the principle and effect of the present utility model, and is not intended to limit the present utility model. All variations, modifications and substitutions within the spirit and principle of the present design are within the protection scope of the present utility model.
