Description

Technical Field

[0001] The utility model relates to a water outlet device and a water purifier. Background Art

[0002] As commercial water purifiers become more and more popular, people's requirements for the use of commercial water purifiers are also getting higher and higher. At present, the room temperature water of many commercial direct drinking machines is generally stored in water storage barrels. The initial water pressure of the water storage barrel is relatively large after it is full of water, which causes water to always spray out from the water outlet when the user uses it, affecting the user experience. At present, in order to prevent the water nozzle from spraying, many current water purifiers are equipped with drainage plates in the water nozzles, but the drainage effect of this drainage plate is not good, especially when there is a certain air pressure difference between the water purifier and the outside, it is easy to cause water to splash out of the water outlet, affecting the user experience. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defect that the water spout in the prior art easily causes water splashing, and to provide a water spout device and a water purifier.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A water outlet device, the water outlet device comprising:

[0006] case;

[0007] A central tube installed inside the shell;

[0008] The central tube has a water inlet and a water outlet and a water flow channel connected to the water inlet and the water outlet;

[0009] A flow guide member is installed at the water outlet, and the middle part of the flow guide member has a flow guide hole and a plurality of drainage holes arranged around the flow guide hole, the inner diameter of the flow guide hole is smaller than the inner diameter of the water flow channel, and the depths of the flow guide hole and the drainage hole along the water flow direction are not less than a preset depth value.

[0010] In the present solution, the water outlet device is provided with a guide member at the water outlet of the central tube, and the guide member is provided with a guide hole and a plurality of drainage holes, so that the guide member forms a plurality of partition walls. When water flows through the guide member, it is separated by the partition walls. At the same time, the inner wall of the middle guide hole plays a role in draining and stabilizing the water in the middle, and the inner wall of the drainage hole on the peripheral side plays a role in draining and stabilizing the water at the edge to prevent water splashing. The depth of the guide hole and the drainage hole along the water flow direction is not less than the preset depth value, thereby improving the water drainage and flow stabilization effect, and preventing the guide member from being too thin, resulting in the shallow depth of the guide hole and the drainage hole, and poor drainage and flow stabilization effect.

[0011] When water enters the water flow channel from the water inlet and then flows through the guide holes and a plurality of drainage holes on the guide member, it is separated by the partition wall of the guide member and then guided and stabilized by the partition wall, so that the outflowing water no longer splashes and the water shape is beautiful.

[0012] Preferably, the water outlet device also includes a guide net, which is installed between the central tube and the guide member. The middle part of the guide net has a blocking portion, and the projection of the blocking portion along the water flow direction covers the guide hole. The guide net has a plurality of diversion holes, and the diversion holes are arranged around the blocking portion.

[0013] In this solution, a guide net is arranged upstream of the guide member, and the blocking part of the guide net prevents the water from directly rushing into the guide hole, reducing the flow rate of the water. The water can only flow into the guide member through a plurality of diversion holes, slowing down the water flow, reducing the water pressure, and avoiding water splashing at the water outlet. Preferably, a plurality of diversion holes are evenly spaced around the blocking part to improve the uniformity of the water.

[0014] Preferably, the middle portion of the guide net bulges toward the direction of incoming water to form an arc-shaped structure.

[0015] In this solution, the arc-shaped structure can quickly divert water in the middle to the surrounding edges, so that water can quickly flow out through the diversion holes at the edges without splashing at the water outlet, preventing the water resistance of the guide net from being too large and causing the water flow rate to be too low.

[0016] Preferably, one end of the guide member close to the guide net matches the bottom of the arc-shaped structure, and a preset gap is reserved between the guide net and the guide member.

[0017] In this solution, one end of the guide member close to the guide net matches the bottom of the arc-shaped structure, which facilitates the transfer of water in the middle to the surrounding side and reduces the water pressure in the middle. A preset gap is retained between the guide net and the guide member, so that water flows evenly through the preset gap, thereby improving the uniformity of the water flow.

[0018] Preferably, the water outlet device further comprises a sealing ring, which is installed between the guide net and the central tube and is used to seal the gap between the peripheral edges of the guide net and the central tube.

[0019] In this solution, a sealing ring is provided to improve the sealing effect and prevent water from overflowing.

[0020] Preferably, the water outlet device further comprises a first fastener, the first fastener is sleeved on the peripheral side of the flow guide, and the first fastener is embedded in the interior of the housing;

[0021] And / or, the water outlet device further includes a second fastener, the second fastener is sleeved on the central tube, and the second fastener is snap-connected to the shell.

[0022] In this solution, the first fastener fixes the guide member inside the shell to prevent the guide member from swinging under the reaction of water. The second fastener fixes the central tube on the shell to improve the fixing effect.

[0023] Preferably, the preset depth value is 15 mm.

[0024] In this solution, the preset depth value is set to 15 mm to improve the water drainage and flow stabilization effects.

[0025] Preferably, a plurality of the drainage holes are evenly spaced around the guide hole.

[0026] In this solution, the above-mentioned structural arrangement is adopted to make water flow evenly through the guide member, thereby improving the uniformity of the water.

[0027] Preferably, the drainage hole is fan-shaped, and the small end of the fan-shaped hole is arranged close to the drainage hole.

[0028] In this solution, the above-mentioned structural setting is adopted, and the fan-shaped drainage holes make most of the water flow to the edge of the guide member, reducing the water flow in the middle, that is, reducing the water pressure in the middle, to achieve a better drainage and stabilizing flow effect.

[0029] A water purifier comprises the water outlet device as described above.

[0030] On the basis of conforming to the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present utility model.

[0031] The positive progressive effect of the utility model is that: the water outlet device is equipped with a guide member at the water outlet of the central tube, and the guide member is provided with a guide hole and a plurality of drainage holes, so that the guide member forms a plurality of partition walls. When water flows through the guide member, it is separated by the partition walls. At the same time, the inner wall of the guide hole in the middle plays a role in draining and stabilizing the water in the middle, and the inner wall of the drainage hole on the peripheral side plays a role in draining and stabilizing the water at the edge to prevent water splashing. The depth of the guide hole and the drainage hole along the water flow direction is not less than a preset depth value, thereby improving the water drainage and flow stabilization effect, and preventing the guide member from being too thin, resulting in the shallow depth of the guide hole and the drainage hole, and poor drainage and flow stabilization effect.

[0032] When water enters the water flow channel from the water inlet and then flows through the guide holes and a plurality of drainage holes on the guide member, it is separated by the partition wall of the guide member and then guided and stabilized by the partition wall, so that the outflowing water no longer splashes and the water shape is beautiful.

[0056] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0057] like Figure 1-Figure 7 As shown, the present embodiment discloses a water outlet device, which includes a shell 1, a central tube 2 and a guide member 3. The central tube 2 is installed inside the shell 1. The central tube 2 has a water inlet 21 and a water outlet 22 and a water flow channel connected to the water inlet 21 and the water outlet 22. The guide member 3 is installed at the water outlet 22. The middle part of the guide member 3 has a guide hole 31 and a plurality of drainage holes 32 arranged around the guide hole 31. The inner diameter of the guide hole 31 is smaller than the inner diameter of the water flow channel. The depths of the guide holes 31 and the drainage holes 32 along the water flow direction 10 are not less than a preset depth value.

[0058] like Figure 4-Figure 6 As shown, the water outlet device is provided with a guide member 3 at the water outlet 22 of the central tube 2, and a guide hole 31 and a plurality of drainage holes 32 are arranged on the guide member 3, so that the guide member 3 forms a plurality of partition walls. When water flows through the guide member 3, it is separated by the partition walls. At the same time, the inner wall of the guide hole 31 in the middle plays a role in draining and stabilizing the water in the middle, and the inner wall of the drainage hole 32 on the peripheral side plays a role in draining and stabilizing the water at the edge to prevent water splashing. The depths of the guide holes 31 and the drainage holes 32 along the water flow direction 10 are not less than the preset depth value, so as to improve the water drainage and stabilization effect, and prevent the guide member 3 from being too thin, resulting in the shallow depths of the guide holes 31 and the drainage holes 32, and poor drainage and stabilization effects.

[0059] When water enters the water flow channel from the water inlet 21 and then flows through the guide holes 31 and a plurality of drainage holes 32 on the guide member 3, it is separated by the partition wall of the guide member 3 and then guided and stabilized by the partition wall, so that the outgoing water no longer splashes and the water shape is beautiful.

[0060] In this embodiment, the preset depth value is 15 mm, which improves the water drainage and flow stabilization effects.

[0061] like Figure 4 and Figure 5 As shown, in this embodiment, a plurality of drainage holes 32 are evenly spaced around the guide hole 31, so that water flows evenly through the guide member 3, thereby improving the uniformity of the water.

[0062] like Figure 4 and Figure 5 As shown, in this embodiment, the drainage hole 32 is fan-shaped, and the small end of the fan is arranged close to the guide hole 31. The fan-shaped drainage hole 32 allows most of the water to flow to the edge of the guide member 3, reducing the water flow in the middle, that is, reducing the water pressure in the middle, to achieve a better drainage and stabilizing effect.

[0063] like Figure 3 , Figure 4 and Figure 7As shown, in this embodiment, the water outlet device further includes a guide net 4, which is installed between the central tube 2 and the guide member 3. The middle part of the guide net 4 has a blocking portion 41, and the projection of the blocking portion 41 along the water flow direction 10 covers the guide hole 31. The guide net 4 has a plurality of diverter holes 42, which are arranged around the blocking portion 41. The guide net 4 is arranged upstream of the guide member 3, and the blocking portion 41 of the guide net 4 prevents the water from directly rushing into the guide hole 31, reducing the flow rate of the water. The water can only flow to the guide member 3 through the plurality of diverter holes 42, slowing down the water flow, reducing the water pressure, and avoiding water splashing at the water outlet 22. Preferably, the plurality of diverter holes 42 are evenly spaced around the blocking portion 41 to improve the uniformity of the water.

[0064] like Figure 4 and Figure 7 As shown, in this embodiment, the middle part of the guide net 4 protrudes toward the direction of the incoming water to form an arc-shaped structure 43. The arc-shaped structure 43 can quickly divert the water in the middle to the surrounding edges, so that the water can quickly flow out through the diversion holes 42 at the edges without splashing at the water outlet 22, thereby preventing the water resistance of the guide net 4 from being too large and causing the water flow rate to be too low.

[0065] like Figure 4 As shown, in this embodiment, one end of the guide member 3 close to the guide net 4 matches the bottom of the arc-shaped structure 43, so as to facilitate the water in the middle to move to the peripheral side and reduce the water pressure in the middle. At the same time, a preset gap is reserved between the guide net 4 and the guide member 3, so that water flows evenly through the preset gap, thereby improving the uniformity of the water flow.

[0066] When water flows in from the water inlet 21, the water will first be sprayed onto the upper surface of the guide net 4. However, since there is no hole in the middle of the upper surface of the guide net 4, the water cannot flow out at this time and can only flow out quickly from the diversion holes 42 around the guide net 4. At the same time, the diversion holes 42 not only effectively reduce the water inlet flow rate of the water inlet 21, but also divide the water into several small water columns. These small water columns are further divided and formed by the guide member 3 to form a double-partitioned water outlet structure. At this time, the water at the water outlet 22 is no longer sprayed, but is discharged according to the divided shape of the guide member 3.

[0067] like Figure 3 and Figure 4 As shown, in this embodiment, the water outlet device also includes a sealing ring 5, which is installed between the guide net 4 and the central tube 2 to seal the gap between the surrounding edges of the guide net 4 and the central tube 2 to prevent water from overflowing and improve the sealing effect.

[0068] like Figure 2-Figure 5As shown, in this embodiment, the water outlet device further includes a first fastener 6, which is sleeved on the circumference of the guide member 3 and embedded in the housing 1. The first fastener 6 fixes the guide member 3 inside the housing 1 to prevent the guide member 3 from swinging under the reaction of water.

[0069] like Figure 1-Figure 4 As shown, in this embodiment, the water spout device further includes a second fastener 7, which is sleeved on the central tube 2 and is snap-connected to the housing 1. The second fastener 7 fixes the central tube 2 to the housing 1, thereby improving the fixing effect. The second fastener 7 is snap-connected to the housing 1, which is also convenient for disassembly and assembly, thereby improving the speed of disassembly and assembly. A protrusion is provided on the second fastener 7, and a groove is provided on the housing 1. The protrusion is embedded in the groove to form a snap-connection.

[0070] The central tube 2 can be made of stainless steel or an injection molded part.

[0071] In order to facilitate the rapid positioning and fixing of the shell 1 and the body of the water purifier, the upper surface of the shell 1 is provided with fixing holes and limiting columns.

[0072] The flow guide 3 is threadedly connected to the central tube 2. The outer peripheral surface of the flow guide 3 is a hexahedron, which is convenient for disassembly and assembly.

[0073] In this embodiment, the housing 1, the central tube 2 and the flow guide 3 are separately arranged components to increase assembly speed. In other alternative embodiments, the housing and the central tube can be arranged integrally, or the housing, the central tube and the flow guide 3 can be arranged integrally.

[0074] This embodiment also discloses a water purifier, which includes the water outlet device as described above.
