[0002] Existing waterscape return inlet designs often cannot effectively cope with the inflow of lightweight debris such as leaves and plastic bags that are common in the natural environment. These debris easily accumulate at the return inlet, causing blockage and affecting the normal operation of the water circulation system. Once a blockage occurs, due to design defects, the cleaning work becomes extremely difficult, which is not only time-consuming and labor-intensive, but sometimes even requires professional intervention, increasing maintenance costs. Utility Model Content

[0003] The main purpose of the utility model is to provide a water return device and a sewage discharge system, which are intended to separate debris and water, reduce the blockage of the water return device by debris, and improve the stability of the operation of the water return device.

[0004] In order to achieve the above-mentioned purpose, the utility model proposes a water return device, comprising:

[0005] A box body, the upper end of which is open, the box body having a first side wall in the transverse direction, the bottom of the box body being divided into a storage area and a water flow area in the transverse direction, the storage area being located between the first side walls of the water flow area, and the water flow area being provided with a plurality of water flow holes; and

[0006] The cover body is arranged to cover the upper end of the box body and has a gap between the cover body and the upper end of the first side wall to define a water inlet therebetween. The cover body is movably arranged relative to the box body to be able to cover and open the open end of the box body.

[0007] In one embodiment, the cover is slidably arranged at the upper end of the box body along the transverse direction.

[0008] In one embodiment, a blocking protrusion is provided on the water flow area and adjacent to the storage area.

[0009] In one embodiment, at least a portion of the upper end of the first side wall is recessed, so that the water inlet is defined between the upper end of the first side wall and the cover body.

[0010] In one embodiment, a guide surface is formed at the upper end of the first side wall, and the guide surface is arranged to be inclined downward in a direction close to the interior of the box body.

[0011] In one embodiment, the upper end of the first side wall is folded in the transverse direction to form a folded edge extending in the transverse direction and arranged obliquely, and the upper side surface of the folded edge forms the guide surface.

[0012] In one embodiment, the folded edge is folded outward from the upper end of the first side wall.

[0013] In one embodiment, a support surface is provided on the upper portion of the box body, and a sliding surface is provided at the lower end of the cover body and is in sliding engagement with the support surface.

[0014] In one embodiment, the upper end of the cover has at least one installation area for arranging a decorative element.

[0015] The utility model provides a sewage discharge system, including the water return device, and the water return device includes:

[0016] A box body, the upper end of which is open, the box body having a first side wall in the transverse direction, the bottom of the box body being divided into a storage area and a water flow area in the transverse direction, the storage area being located between the first side walls of the water flow area, and the water flow area being provided with a plurality of water flow holes; and

[0017] The cover body is arranged to cover the upper end of the box body and has a gap between the cover body and the upper end of the first side wall to define a water inlet therebetween. The cover body is movably arranged relative to the box body to be able to cover and open the open end of the box body.

[0018] In the technical solution of the present invention, the water inlet provided between the cover and the box body allows wastewater mixed with debris to pass over the first side wall and enter the box body through the water inlet. At this time, under the action of gravity, the wastewater mixed with debris falls into the storage area. After entering the bottom of the storage area, the wastewater flows horizontally to the water flow area and then flows out of the water flow hole located in the water flow area. As the wastewater flows away, the debris is separated from it and, under the action of gravity, is deposited in the storage area and the water flow area. Because the storage area is located between the first side walls of the water flow area, the debris deposited in the storage area is greater than that in the water flow area, thereby reducing the blockage of the water flow hole by debris and improving the stability of the operation of the water return device. When too much debris is deposited in the box body and the drainage of the water hole is affected, the debris in the box body can be cleaned by opening the cover body movably arranged at the open end of the box body, and the cover body can be re-covered on the open end of the box body after cleaning.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] Existing waterscape return inlet designs often cannot effectively cope with the inflow of lightweight debris such as leaves and plastic bags that are common in the natural environment. These debris easily accumulate at the return inlet, causing blockage and affecting the normal operation of the water circulation system. Once a blockage occurs, due to design defects, the cleaning work becomes extremely difficult, which is not only time-consuming and labor-intensive, but sometimes even requires professional intervention, increasing maintenance costs.

[0033] like Figure 1 and Figure 2 As shown, in order to solve the above technical problems, the present invention proposes a water return device 100, comprising a box body 1 and a cover body 2. The upper end of the box body 1 is open, and the box body 1 has a first side wall 11 in the transverse direction. The bottom of the box body 1 is divided into a storage area 12 and a water flow area 13 in the transverse direction. The storage area 12 is located between the water flow area 13 and the first side wall 11. The water flow area 13 is provided with a plurality of water flow holes 14; the cover body 2 is arranged to cover the upper end of the box body 1, and a gap is formed between the cover body 2 and the upper end of the first side wall 11 to define a water inlet 15 therebetween. The cover body 2 is movably arranged relative to the box body 1 to be able to cover and open the open end of the box body 1.

[0034] In the technical solution of the present invention, the water inlet 15 provided between the cover 2 and the box body 1 allows wastewater mixed with impurities to pass over the first side wall 11 and enter the box body 1 through the water inlet 15. At this time, under the action of gravity, the wastewater mixed with impurities falls into the storage area 12. After entering the bottom of the storage area 12, the wastewater flows laterally to the water flow area 13 and then flows out of the water flow hole 14 located in the water flow area 13. As the wastewater flows away, impurities are separated from it and, under the action of gravity, are deposited in the storage area 12 and the water flow area 13. Because the storage area 12 is located between the first side wall 11 of the water flow area 13, more impurities are deposited in the storage area 12 than in the water flow area 13, thereby reducing the blockage of the water flow hole 14 by impurities and improving the operational stability of the water return device 100. When too much debris is deposited in the box body 1 and the drainage of the water hole 14 is affected, the debris in the box body 1 can be cleaned by opening the cover 2 movably arranged at the open end of the box body 1, and the cover 2 can be re-closed on the open end of the box body 1 after cleaning.

[0035] It can be understood that the movable setting of the cover body 2 and the box body 1 can be through a hinge connection (the cover body 2 is connected to the box body 1 through a hinge, so that the cover body 2 can be rotated to open or close within a certain range.), a snap connection (a snap is provided on the edge of the cover body 2, and a snap groove is provided at the corresponding position of the box body 1. Through the cooperation of the snap and the snap groove, the cover body 2 can be firmly fixed on the box body 1, and it is also convenient to open.) or a sliding setting.

[0036] In one embodiment, the cover 2 is slidably disposed in a transverse direction on the upper end of the box body 1. In this way, by sliding the cover 2 in a transverse direction, the open end of the box body 1 can be opened without tilting or completely removing the cover 2, thereby cleaning out debris therein and reducing the difficulty of opening the cover 2.

[0037] In one embodiment, a support surface is provided on the upper portion of the box body 1, and a sliding surface is provided on the lower end of the cover body 2 and slides with the support surface. In this way, the support surface and the sliding surface are in contact and slide with each other, so that the two generate relative motion. And because the box body 1 and the cover body 2 are in surface contact, the stability of the connection between the two is increased, and the cover body 2 can slide smoothly on the box body 1. The sliding surface can be formed by protruding on the side wall of the upper end of the box body 1 to form the support surface, or a guide rail is provided on the side wall of the upper end of the box body 1 to form the support surface. The sliding surface is the part where the lower end surface of the cover body 2 contacts the support surface.

[0038] like Figure 3and Figure 4 As shown, since the water return device 100 of the present invention is located next to a pool, the box body 1 can be configured to suit the length of different pools. When the cover body 2 is longitudinally extended, the area of ​​the support surface needs to be further increased to further enhance the stability of the connection between the cover body 2 and the box body 1. To this end, in one embodiment, a support portion 17 is provided longitudinally on the upper portion of the box body 1, with the upper end of the support portion 17 forming the support surface. This longitudinally extended support portion 17 increases the contact area between the support surface and the sliding surface, thereby enhancing the stability of the cover body 2 on the box body 1. There are various ways to configure the support portion 17. For example, the support portion 17 can be configured as a flat plate, so that the upper end of the plate can contact the lower end of the cover body 2. Alternatively, the support portion 17 can be configured as multiple circular tubes arranged side by side. The circular tubes can withstand greater pressure, thereby enhancing the support effect on the lower end of the cover body 2. It should be noted that the size of the plate material of the round tube can be set according to actual needs and is not particularly limited here.

[0039] Furthermore, in order to improve the smoothness between the support portion 17 and the cover 2 and reduce the sliding wear therebetween, thereby improving the convenience of use and the lifespan, in some embodiments, balls, bearings, and lubricating oil may be provided on the support portion 17, either singly or in combination, to reduce the friction between the support surface and the sliding surface.

[0040] Since the sliding direction of the cover body 2 in the lateral direction can be toward the side of the pool or toward the side of the land surface, it is necessary to control the sliding stroke between the cover body 2 and the box body 1 regardless of whether it is toward the pool or the land surface. To this end, a limiting structure can be provided to limit the sliding stroke of the box body 1, for example, by a mechanical limit block, an elastic limiter or a magnetic limiter. Specifically, in one embodiment, a plurality of support portions 17 are provided, and a limiting protrusion 21 is provided on the lower end of the cover body 2 toward the direction of the opening, and the limiting protrusion 21 is provided between two adjacent support portions 17. In this way, when the cover body 2 slides to the edge of the box body 1, the limiting protrusion 21 can contact and stop the support portion 17, thereby reducing the possibility of the cover body 2 moving excessively and detaching from the box body 1 during the sliding process, thereby improving the reliability of the use of the water return device 100. The shape of the limiting protrusion 21 can be a cylindrical limiting protrusion 21, a rectangular limiting protrusion 21, a triangular limiting protrusion 21, or a special-shaped limiting protrusion 21, without particular limitation. Specifically, in one embodiment, a plurality of limiting protrusions 21 can be provided to disperse the limiting pressure of a single limiting protrusion 21. Furthermore, a connecting portion is provided between two adjacent limiting protrusions 21, and the connecting portion abuts against the support portion 17 to limit the movement direction between the limiting protrusion 21 and the support portion 17.

[0041] Since some debris will flow into the water flow area 13 along with the wastewater, debris will be present in the water flow area 13, causing blockage of the water flow hole 14, thereby reducing the drainage volume of the water flow hole 14. In view of this, in one embodiment, a blocking protrusion 16 is provided on the water flow area 13 and adjacent to the storage area 12. In this way, the blocking portion blocks the debris in the storage area 12, thereby reducing the amount of debris in the storage area 12 that can remain in the storage area 12 as much as possible, reducing the blockage of the water flow hole 14 in the water flow area 13, increasing the drainage volume of the water flow hole 14, and reducing the cleaning cycle of the debris in the box. The blocking portion can be set as a protrusion, a grid, or a filter structure.

[0042] It can be understood that the water inlet 15 is used to allow wastewater containing impurities in the pool to enter the box body 1 through here. To this end, the water inlet 15 can be set at the lower end of the cover body 2 or on the first side wall 11, or between the first side wall 11 and the cover body 2 and spaced relative to the two. Specifically, in one embodiment, the upper end of the first side wall 11 is at least partially recessed so that the water inlet 15 is defined between the upper end of the first side wall 11 and the cover body 2. This arrangement allows the water inlet 15 to independently maintain the function of returning water at all times without being affected by the state of the cover body 2. The shape of the water inlet 15 can be designed to be rectangular, circular or other shapes according to actual needs to ensure that wastewater mixed with impurities can flow smoothly. In addition, the first side wall 11 can be partially recessed to form one or more water inlets 15, or all of it can be recessed and extended along the longitudinal direction of the box body 1.

[0043] In order to allow wastewater mixed with debris to flow smoothly through the water outlet, in one embodiment, a guide surface 111 is formed at the upper end of the first side wall 11. The guide surface 111 is arranged to be inclined downward in the direction close to the interior of the box body 1. In this way, by simultaneously utilizing the principles of gravity and fluid mechanics, the flow efficiency is improved. When wastewater flows in from the upper end of the first side wall 11, the inclined design of the guide surface 111 can guide the wastewater and the debris therein to flow smoothly along the guide surface 111, reducing the accumulation of debris at the water outlet and thus avoiding the occurrence of blockage. At the same time, the inclined guide surface 111 also helps to reduce the resistance of the wastewater during flow, accelerate the speed of the wastewater, and use the kinetic energy of the wastewater to further push the debris through. It is understandable that the setting method of the guide surface 111 can be achieved by providing a guide plate or a guide pipe at the upper end of the first side wall 11.

[0044] In order to facilitate the setting of the guide surface 111, in one embodiment, the upper end of the first side wall 11 is folded laterally to form a folded edge 112 that extends laterally and is arranged at an angle, and the upper side surface of the folded edge 112 forms the guide surface 111. In this way, through a simple folding operation, the required guide surface 111 can be formed without the need for additional materials or complex processing. This reduces production costs and simplifies the manufacturing process. The folded edge 112 and the first side wall 11 are integrally formed, so they have high structural strength and durability. This ensures that the guide surface 111 is not easily damaged or deformed during long-term use, thereby extending the service life of the equipment. In addition, it should be noted that in order to improve the use strength of the return water device 100, the return water device 100 is made of metal materials, such as iron, steel, copper, aluminum alloy and stainless steel. The one-piece folding arrangement can reduce connection marks produced at the folded corners and reduce damage to the first side wall 11 , thereby improving the corrosion resistance of the first side wall 11 and extending the service life of the water return device 100 .

[0045] Since the first side wall 11 is positioned adjacent to the pool, in order to further enhance the installation strength of the folded edge 112, in one embodiment, the folded edge 112 is folded outward from the upper end of the first side wall 11. This allows the lower end surface of the folded edge 112 to abut against the installation environment, providing additional support for the folded edge 112 and helping to reduce the possibility of the folded edge 112 loosening or deformation due to stress during long-term use.

[0046] Since the cover plate is directly exposed to the outside, it would be obtrusive to the surrounding environment and reduce the aesthetic appeal. In one embodiment, the upper end of the cover body 2 has at least one mounting area for decorative elements. Thus, by placing decorative elements such as stones, flowers, and trees on the mounting area, the cover body 2 can be integrated with the surrounding environment, obscuring the view and enhancing its aesthetics. It is understood that the decorative elements can be secured in the mounting area by means of glue, mounting holes, grooves, or connectors 22.

[0047] To facilitate the installation of decorative components, in one embodiment, the mounting area is provided with a longitudinally extending connector 22. The upper portion of the connector 22 is clearance-fitted with the mounting area to define a mounting groove. This allows the decorative component to be positioned within the mounting groove, enabling longitudinal movement. Due to friction between the decorative component and the upper end surface of the cover 2, the decorative component secured to the mounting area by the connector 22 remains secure without external forces. Lateral movement of the cover 2 will not affect the decorative component. To enhance symmetry, the connector 22 is V-shaped.

[0048] In one embodiment, to enhance the mounting strength of the water return device 100, a mounting portion is provided on the outside of the housing 1. The mounting portion has a through hole through which a bolt can pass to secure the housing 1. One or more mounting portions may be provided, and the mounting portion may be located at the upper or lower end of the housing 1, depending on actual site requirements and not specifically limited herein.

[0049] The present invention also proposes a sewage discharge system, which includes a return water device 100. The specific structure of the return water device 100 refers to the above embodiment. Since the sewage discharge system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0050] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
