Description

Technical Field

[0001] The utility model relates to the field of bathroom products, in particular to a water drainage device. Background Art

[0002] Shower water is popular among consumers because it has multiple columnar water flows, strong impact force and good cleaning performance. For example, Chinese patent CN204781152U has developed a bubbler with inner circle bubble water and outer circle shower water, which can realize inner circle or outer circle water discharge by switching the water path. Another similar water discharge device is CN216910655U. However, when the shower water of these two products is discharged, the water flow from top to bottom impacts the end face between the entrances of two adjacent water outlets, and the water flow rebounds in the connection area between the water outlets. Please refer to CN216910655U Figure 3 , the water flow will impact the end surface above the water outlet 14; or please refer to CN204781152U Figure 5 and Figure 6 , the water flow will impact the end face above the outer ring net 71, causing the water flow to rebound. Even if the first finishing net 50 is housed, it is still impossible to avoid the water flow impacting the end face above the outer ring net 71 downwards.

[0003] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

[0004] The main purpose of the utility model is to provide a water drainage device, which solves the problem mentioned in the background technology that water flow impacts the end surface between adjacent water outlets to cause rebound and affect the water flow through the water outlets, and can quickly guide the water flow into the water outlets for discharge.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A water drainage device comprises a water outlet end plate and a drainage body, wherein a plurality of water outlet holes are formed on the water outlet end plate; the drainage body is located between the entrances of two adjacent water outlet holes, the drainage body comprises a first guide surface and a second guide surface, a ridge line is formed at the junction of the tops of the first guide surface and the second guide surface, and the ridge line is located at the highest point of the drainage body; the first guide surface and the second guide surface extend obliquely from the ridge line toward the entrances of the water outlet holes on the corresponding sides.

[0007] Furthermore, the bottom of the guide body is integrally formed on the water outlet end plate between the inlets of two adjacent water outlet holes.

[0008] Furthermore, the drainage and water outlet device also includes an inner surrounding wall and an outer surrounding wall; the water outlet end plate is connected to the inner surrounding wall and the outer surrounding wall; a plurality of water outlet holes are distributed on the water outlet end plate at annular intervals and surround the inner surrounding wall; the drainage body is integrally connected to the inner surrounding wall and / or the outer surrounding wall, and the ridges on the drainage body extend to the inner surrounding wall and the outer surrounding wall.

[0009] Furthermore, the water outlet end plate is installed between the inner surrounding wall and the outer peripheral wall; the diversion body is integrally connected to the inner surrounding wall and the outer peripheral wall, and the bottom of the diversion body is separately arranged from the water outlet end plate; the bottom of the diversion body is in contact with the water outlet end plate between the entrances of two adjacent water outlet holes.

[0010] Furthermore, the water outlet end plate is annular, the water outlet end plate is integrally connected to the inner surrounding wall and the outer surrounding wall, and the bottom of the guide body is integrally formed on the water outlet end plate between the inlets of two adjacent water outlet holes.

[0011] Furthermore, along the projection direction perpendicular to the water outlet end plate, the diversion body occupies half or more of the area of ​​the water outlet end plate region between the water outlet holes; the height between the highest point of the diversion body and the entrance of the water outlet hole is less than the height of the water outlet hole; and the minimum distance between the bottom edges of the first guide surface and the second guide surface is greater than the diameter of the water outlet hole.

[0012] Further, the first guide surface and the second guide surface are symmetrically arranged, and the ridge line is located at the center position of two adjacent water outlet holes; or, the first guide surface and the second guide surface are asymmetrically arranged, and the distance between the ridge line and the water outlet hole corresponding to the first guide surface is smaller than the distance between the ridge line and the water outlet hole corresponding to the second guide surface.

[0013] Furthermore, a plurality of water outlet holes on the water outlet end plate are distributed in a single ring shape; and the first guide surface on the guide body is arranged opposite to the second guide body on the adjacent guide body.

[0014] Furthermore, a plurality of mutually adjacent water outlet holes share a drainage body, and a plurality of ridge lines on the drainage body are connected to form a cone point.

[0015] Furthermore, the first guide surface and / or the second guide surface extends from the ridge line to the inlet edge of the water outlet.

[0016] After adopting the above structure, the water drainage device of the utility model has at least the following beneficial effects:

[0017] 1. The water flow entering from upstream impacts the drainage body, and the first guide surface and the second guide surface quickly guide the water flow to the corresponding side of the water outlet for discharge, avoiding the water flow rebounding in the connection area between the water outlets, so as to reduce the situation where the water hammer effect hinders the water flow. In addition, the water flow flowing along the first guide surface and the second guide surface toward the water outlet will also guide the upstream water flow, so that the water flow is concentrated toward the water outlet, reducing the energy loss of the water flow and increasing the water outlet speed and impact force. Since the top junction of the first guide surface and the second guide surface forms a ridge, the water-facing surface at the junction is very small, which can smoothly split the oncoming water flow and guide it to the first guide surface and the second guide surface on both sides.

[0018] Second, the guide body can be formed on the water outlet end plate; it can also be formed on other components, such as being set on the inner wall or the outer wall. In this way, the water outlet end plate can be replaced with a water outlet end plate with different water splash effects, and it only needs to have the same number and layout of water outlet inlets as the water outlet end plate before replacement.

[0019] The diversion body can also be integrally formed on the water outlet end plate and then assembled to components such as the inner surrounding wall and the outer surrounding wall. In this way, water outlet end plates with different numbers of water outlet holes can be easily selected for installation. Since the diversion body is integrally produced on the water outlet end plate during injection molding of the water outlet end plate, other components such as the inner surrounding wall and the outer surrounding wall of the water outlet device can use the original components without any changes.

[0020] The drainage body, the water outlet end plate, the inner surrounding wall and the outer surrounding wall may also be integrally injection molded, which not only increases the connection strength but also saves the assembly step.

[0021] 3. When there are multiple adjacent water outlet holes around the water outlet hole, a guide body is arranged between the adjacent water outlet holes, and a cone point is formed at the connection of the ridges of the multiple guide bodies, so that the water flow impacting the cone point is guided to multiple guide surfaces and guided to the water outlet holes on the corresponding side.

[0022] Compared with the prior art, the utility model can quickly guide the water flow rushing toward the water outlet end plate to the water outlet hole for discharge, avoiding the water flow directly impacting the end surface between two adjacent water outlet holes and rebounding to produce water hammer, thereby ensuring that the water flow discharged from the water outlet hole has better speed and impact force.

[0037] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0038] like Figures 2 to 11 As shown, it is a drainage and water outlet device involved in the utility model, including a water outlet end plate 1 and a drainage body 2, and a plurality of water outlet holes 11 are formed on the water outlet end plate 1; the drainage body 2 is located between the entrances of two adjacent water outlet holes 11, and the drainage body 2 has a first guide surface 21 and a second guide surface 22, and a ridge line 23 is formed at the top junction of the first guide surface 21 and the second guide surface 22, and the ridge line 23 is located at the highest point of the drainage body 2; the first guide surface 21 and the second guide surface 22 extend obliquely from the ridge line 23 toward the entrance direction of the water outlet hole 11 on the corresponding side.

[0039] Thus, compared to Figure 1For a water outlet device without a guide body 2, the utility model sets a guide body 2, and the water flow entering from the upstream impacts the guide body 2, and the first guide surface 21 and the second guide surface 22 quickly guide the water flow to the corresponding side of the water outlet 11 for discharge, thereby avoiding the water flow from rebounding in the connection area between the water outlets 11, and reducing the situation where the water hammer effect hinders the water flow. Moreover, the water flow flowing toward the water outlet 11 along the first guide surface 21 and the second guide surface 22 will also guide the upstream water flow, so that the water flow is concentrated toward the water outlet 11 (such as Fig. 9 As shown in the figure), it reduces the energy loss of water flow and increases the water outlet speed and impact force.

[0040] Since the top junction of the first guide surface 21 and the second guide surface 22 forms a ridge 23, the water-facing surface at the junction is very small, and the oncoming water flow can be smoothly split and directed to the first guide surface 21 and the second guide surface 22 on both sides. It should be noted that due to mold processing reasons, a process chamfer needs to be formed at the ridge 23 instead of completely turning from the first guide surface 21 to the second guide surface 22 without transition. Of course, this process chamfer only eliminates the tip of the ridge 23 to facilitate injection molding, and the ridge 23 itself is still very narrow.

[0041] As the first embodiment of the present application, the bottom of the diversion body 2 is integrally formed on the water outlet end plate 1 between the entrances of two adjacent water outlet holes 11, and the water outlet end plate 1 is then assembled to components such as the inner surrounding wall 3 and the outer surrounding wall 4. In this way, water outlet end plates 1 with different numbers of water outlet holes 11 can be conveniently selected for installation. Since the diversion body 2 has been integrally produced on the water outlet end plate 1 when the water outlet end plate 1 is injection molded, other components such as the inner surrounding wall 3 and the outer surrounding wall 4 of the water outlet device can use the original components without any changes.

[0042] As a second embodiment of the present application, the drainage and water outlet device also includes an inner surrounding wall 3 and an outer wall 4; the water outlet end plate 1 is connected to the inner surrounding wall 3 and the outer wall 4; a plurality of water outlet holes 11 are distributed on the water outlet end plate 1 at annular intervals and surround the inner surrounding wall 3; the drainage body 2 is integrally connected to the inner surrounding wall 3 and / or the outer wall 4; the ridge 23 on the drainage body 2 extends to the inner surrounding wall 3 and the outer wall 4, so that when the water flow passes between the inner surrounding wall 3 and the outer wall 4, it can be fully guided by the drainage body 2 to the entrance of the water outlet hole 11.

[0043] The diversion body 2 is formed integrally on the inner surrounding wall 3 or the outer peripheral wall 4, so that the water outlet end plate 1 can be replaced with a water outlet end plate 1 with different water splash effects, and only needs to have the same number and layout of the water outlet holes 11 inlet as the water outlet end plate 1 before replacement. Preferably, the diversion body 2 is integrally connected with the inner surrounding wall 3 and the outer peripheral wall 4, and the diversion body 2 is supported by the inner surrounding wall 3 and the outer peripheral wall 4, which has better stability, and can make the diversion body 2, the inner surrounding wall 3 and the outer peripheral wall 4 form an integral part and be injection molded together; the water outlet end plate 1 is installed between the inner surrounding wall 3 and the outer peripheral wall 4; the bottom of the diversion body 2 is separately arranged from the water outlet end plate 1, and the bottom of the diversion body 2 contacts the water outlet end plate 1 between the inlets of two adjacent water outlet holes 11, so as to minimize the gap at the bottom of the diversion body 2 and avoid turbulence.

[0044] Preferably, as the third embodiment of the present application, the water outlet end plate 1 is annular, the water outlet end plate 1 is integrally connected with the inner surrounding wall 3 and the outer peripheral wall 4, and the bottom of the diversion body 2 is integrally formed on the water outlet end plate 1 between the inlets of two adjacent water outlet holes 11. The diversion body 2, the water outlet end plate 1, the inner surrounding wall 3 and the outer peripheral wall 4 are integrally injection molded, which not only has high connection strength, but also saves the assembly step.

[0045] Preferably, along the projection direction perpendicular to the water outlet end plate 1, the guide body 2 occupies half or more of the area of ​​the water outlet end plate 1 between the water outlet holes 11; (e.g. Fig.11 (as shown) the height H1 between the highest point of the diversion body 2 and the entrance of the water outlet hole 11 is smaller than the height H2 of the water outlet hole 11.

[0046] like Figure 3 As shown, the minimum distance A between the bottom edges of the first guide surface 21 and the second guide surface 22 is greater than the diameter d of the water outlet 11. By increasing the area occupied by the guide body 2, it is helpful to better guide the water flow and reduce the end surface proportion at the entrance of the water outlet 11. Preferably, the first guide surface 21 and / or the second guide surface 22 extends from the ridge line 23 to the entrance edge of the water outlet 11, so that there is no end surface around the entrance of the water outlet 11, such as Figure 7 shown.

[0047] Preferably, the first guide surface 21 and the second guide surface 22 are symmetrically arranged, and the ridge line 23 is located at the center of two adjacent water outlet holes 11; or Figure 8 The first guide surface 21 and the second guide surface 22 are arranged asymmetrically, and the distance between the ridge line 23 and the water outlet hole 11 corresponding to the first guide surface 21 is smaller than the distance between the ridge line 23 and the water outlet hole 11 corresponding to the second guide surface 22 .

[0048] Preferably, the plurality of water outlet holes 11 on the water outlet end plate 1 are distributed in a single ring shape; the first guide surface 21 on the guide body 2 is arranged opposite to the second guide body 2 on the adjacent guide body 2. In this way, two adjacent water outlet holes 11 each correspond to a first guide surface 21 and a first and second guide surface 22, so that the water outlet effect of the water outlet holes 11 can be kept consistent as much as possible; if not arranged in this way, one of the water outlet holes 11 may correspond to two first guide surfaces 21, and the other water outlet hole 11 may correspond to two second guide surfaces 22, so that the water outlet speeds of the two water outlet holes 11 may be greatly different.

[0049] Preferably, Figure 4 As shown, a plurality of mutually adjacent water outlet holes 11 share a guide body 2, and a plurality of ridges 23 on the guide body 2 are connected to form a cone point 24. When there are a plurality of adjacent water outlet holes 11 around the water outlet hole 11, a guide body 2 is arranged between the adjacent water outlet holes 11, and the connection of the ridges 23 of the plurality of guide bodies 2 forms a cone point 24, so that the water flow impacting on the cone point 24 is directed to a plurality of guide surfaces and directed to the water outlet holes 11 on the corresponding side.

[0050] When multiple circles of water outlet holes 11 are distributed on the annular water outlet end plate 1 , there may be a situation where multiple water outlet holes 11 share one guide body 2 . At this time, the ridge line 23 plays a role similar to a ridge line, guiding the water flow to the corresponding water outlet holes 11 .

[0051] Compared with the prior art, the utility model can quickly guide the water flow rushing toward the water outlet end plate 1 to the water outlet hole 11 for discharge, avoiding the water flow directly impacting the end surface between two adjacent water outlet holes 11 and rebounding to produce water hammer, thereby ensuring that the water flow discharged from the water outlet hole 11 has better speed and impact force.

[0052] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
