[0014] (III) Beneficial effects

[0015] Compared with the prior art, the present utility model provides a water outlet structure for preventing dripping of a water outlet nozzle of a water purifier, which has the following beneficial effects:

[0016] 1. In the water outlet structure for preventing dripping of the water outlet nozzle of the water purifier, the filtered water enters the annular flow channel through the connector. As the liquid level inside the annular flow channel rises, the water flow passes through the diversion port and enters the inside of the water outlet pipe, and then the water flow is divided by the grille, so that the water flow slowly flows down from the water outlet pipe; after stopping draining, when the water droplets inside the water outlet pipe drip downward, under the action of tension, the water droplets adhere to the inner wall of the silica gel pipe, inhibiting the dripping of the water droplets.

[0017] 2. In the water outlet structure for preventing dripping of the water outlet nozzle of the water purifier, the filtered water enters the annular flow channel through the connector. Under the blocking action of the partition plate, it flows in the clockwise direction, and when passing through the flow blocking plate, under the blocking action of the convex strip on the water flow, a turbulent flow is formed, accelerating the discharge of steam in the water. The steam flows upward, passes through the fan-shaped notch, flows above the arc-shaped cover plate, and finally is discharged through the steam pipe, thereby preventing a large amount of steam and water flow from being discharged from the water outlet pipe at the same time, and avoiding the water flow from splashing under the action of steam when discharging water.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 5 , a water outlet structure for preventing dripping of a water purifier water outlet nozzle, including a sleeve 1, a sealing cover 2 is fixedly installed at the top of the sleeve 1, and the top of the sleeve 1 is sealed by the sealing cover 2. A connector 3 is connected and communicated with the side surface of the sleeve 1, a water outlet pipe 4 is arranged along the central axis of the sleeve 1, the top end of the water outlet pipe 4 is fixedly installed at the bottom of the sealing cover 2, the water outlet pipe 4 penetrates through the sleeve 1 and extends below the sleeve 1, a diversion port 5 is formed through the circumferential surface of the upper half of the water outlet pipe 4, and the position of the diversion port 5 is higher than the position of the connector 3. Filtered water is conveyed into the sleeve 1 through the connector 3. As the liquid level inside the sleeve 1 rises, the filtered water then passes through the diversion port 5 and enters the inside of the water outlet pipe 4, and finally is discharged through the water outlet pipe 4. A protection cover 6 is fixedly installed on the circumferential surface of the lower half of the water outlet pipe 4, and the discharged water is blocked by the protection cover 6 to prevent the water from splashing everywhere. A silicone tube 7 is sleeved outside the bottom end of the water outlet pipe 4, and the protection cover 6 is sleeved outside the silicone tube 7. After the drainage is completed, when the remaining water inside the water outlet pipe 4 drips, under the action of tension, it adheres to the silicone tube 7 to inhibit the dripping of water droplets.

[0026] A grille 8 is fixedly installed inside the water outlet pipe 4, and the grille 8 is lower than the bottom wall of the diversion opening 5. The center of the grille 8 is an inner pipe with a regular hexagon cross-section, and connecting bars are connected between the six edges of the inner pipe and the inner wall of the water outlet pipe 4. The grille 8 diverts the water flow inside the water outlet pipe 4, playing a role in slowing down the flow.

[0027] A partition 9 is fixedly installed between the inner wall of the sleeve 1 and the outer wall of the water outlet pipe 4, and the opening of the connector 3 and the diversion opening 5 are separated by the partition 9. Since an annular flow channel is formed between the sleeve 1 and the water outlet pipe 4, and the partition 9 is inside the flow channel, after water is conveyed into the sleeve 1 by the connector 3, under the blockage of the partition 9, the water flow flows in the annular flow channel in the clockwise direction until the flow channel reaches the rear side of the partition 9. Thus, along the distance that the water flow flows inside the sleeve 1, the kinetic energy of the water flow is reduced through the frictional action of the inner wall of the sleeve 1 and the outer wall of the water outlet pipe 4, so that when the water flow enters the inside of the water outlet pipe 4, the flow is relatively slow, avoiding excessive water flow velocity during drainage and splashing everywhere when impacting in containers such as cups.

[0028] The upper part of the circumferential surface of the sleeve 1 is connected with a steam pipe 11. The steam pipe 11 is communicated with the inside of the sleeve 1. The top end of the steam pipe 11 is located above the sealing cover 2, and the bottom end of the steam pipe 11 is higher than the top wall of the diversion opening 5. When hot water enters the inside of the sleeve 1 through the connector 3, steam is discharged from the water and discharged through the steam pipe 11, preventing the steam and the water flow from being discharged from the water outlet pipe 4 at the same time and causing splashing when the hot water is discharged.

[0029] An arc-shaped cover plate 10 is fixedly installed between the inner wall of the sleeve 1 and the outer wall of the water outlet pipe 4. One end of the arc-shaped cover plate 10 is fixedly installed on the front side of the partition 9, and a fan-shaped gap is formed between the other end of the arc-shaped cover plate 10 and the rear side of the partition 9. The arc-shaped cover plate 10 is higher than the top wall of the diversion opening 5 and lower than the bottom end of the steam pipe 11. The arc-shaped cover plate 10 blocks the water flow, preventing the steam from driving the water inside the sleeve 1 to splash upward and enter the inside of the steam pipe 11 when the steam flows upward. The hot water splashed upward by the steam adheres to the bottom of the arc-shaped cover plate 10 and then drips into the inside of the sleeve 1. The steam can flow upward from the fan-shaped gap and then be discharged from the steam pipe 11. A plurality of flow blocking plates 12 are fixedly installed between the bottom wall of the sleeve 1 and the bottom of the arc-shaped cover plate 10. The flow blocking plates 12 are arc-shaped, and the center of the arc of the flow blocking plates 12 coincides with the axis of the sleeve 1. Convex strips 13 are evenly fixed on both sides of the flow blocking plates 12, and the cross-section of the convex strips 13 is triangular. Through the arrangement of the flow blocking plates 12 and the convex strips 13, the water flow is blocked, and turbulence is formed in the annular flow channel, accelerating the discharge of steam in the water.

[0030] Working principle: The filtered water enters the annular flow channel through the connector 3. Under the blocking effect of the partition plate 9, it flows in the clockwise direction. When passing through the flow blocking plate 12, under the blocking effect of the convex strip 13 on the water flow, a turbulent flow is formed, accelerating the discharge of steam in the water. The steam flows upward, passes through the fan-shaped notch, flows above the arc-shaped cover plate 10, and finally is discharged through the steam pipe 11.

[0031] As the liquid level inside the annular flow channel rises, the water flow passes through the diversion port 5 and enters the inside of the water outlet pipe 4. Then, the water flow is shunted by the grille 8, causing the water flow to slowly flow down from the water outlet pipe 4. After stopping the drainage, when the water droplets inside the water outlet pipe 4 drip downward, under the action of tension, the water droplets adhere to the inner wall of the silica gel tube 7, inhibiting the dripping of water droplets.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
