Description

Technical Field

[0001] This utility model relates to the field of water inlet technology, and in particular to a straight-insertion water inlet with a side outlet. Background Technology

[0002] Traditional components in swimming pool water circulation systems, such as inlets and outlets, present numerous problems. Traditional outlets typically only receive water flowing back from the surface or bottom, failing to effectively clean dust and debris accumulated at the bottom. This leads to the long-term accumulation of these impurities, affecting water quality and pool bottom cleanliness. Furthermore, manual cleaning requires tools like vacuum cleaners, making the process cumbersome. Additionally, the upward-facing inlet and outlet of traditional outlets allows impurities to spread outwards, further complicating cleaning. Moreover, traditional outlets often require pre-installation, a complex and time-consuming process that demands skilled installers. Improper installation can result in difficult and costly remediation later. Furthermore, the structural design of some outlets makes them prone to entanglement and blockage by large debris such as hair, hindering removal and cleaning. Long-term accumulation of these debris can affect the normal operation of the water circulation system and may even damage equipment. Therefore, a new type of swimming pool outlet is needed that effectively solves these problems, offering advantages such as efficient cleaning, convenient installation, and easy maintenance, thereby improving the overall performance and ease of maintenance of the swimming pool.

[0003] Chinese patent document CN221878318U discloses a wet pond overflow structure. It primarily addresses the problems of ineffective drainage pressure and pollution, leading to increased costs and construction inconvenience. The proposed technical solution includes: plain soil and a foundation pit excavated within the plain soil; a concrete layer for support, installed at the bottom of the foundation pit; a sewage discharge assembly for rainwater discharge, located within the foundation pit; and a diversion assembly for increasing drainage capacity and collecting clean rainwater, installed on the sewage discharge assembly.

[0004] However, the above solution has at least the following technical problems during implementation: the outlet is located on the top cover, and the vertical design causes dust and debris to accumulate at the outlet, requiring a vacuum cleaner for cleaning, which is labor-intensive and inefficient. Therefore, there is an urgent need to propose a straight-insertion type water outlet with a side outlet. Summary of the Invention

[0005] In view of the above technical problems, this disclosure provides a straight-insertion water outlet with a side outlet, which solves the technical problem that in the prior art, the water outlet is set on the top cover, and the vertical design causes dust and debris to accumulate at the water outlet position, which can only be cleaned with a vacuum cleaner, resulting in a large workload and low work efficiency.

[0006] According to one aspect of this disclosure, a straight-insertion water inlet with side outlets is provided, including a base, a detachable top cover on the base, multiple side outlets on the side of the base, and a return water pipe connected to the base through the side outlets to form a water flow channel. An annular support block is provided on the inner wall of the return water pipe to support an adjustable pressure plate. The diameter of the adjustable pressure plate is smaller than the inner diameter of the return water pipe. An adjusting screw is installed through the middle of the adjustable pressure plate. The adjusting screw is installed in a hollow cylindrical structure. The hollow cylindrical structure is fixed to the annular support block by a connecting rod. The inner wall of the hollow cylindrical structure is provided with a thread that fits the adjusting screw, so that the rotation of the adjusting screw drives the lifting and lowering of the adjustable pressure plate.

[0007] In some embodiments of this disclosure, the base is a hollow frustum shape, with a stepped top surface for mounting a top cover, and the sides are inclined at an angle of 30° to 60° to the horizontal plane.

[0008] In some embodiments of this disclosure, a plurality of bolt holes are evenly distributed circumferentially above the base, and bolts are installed in the bolt holes through elastic sealing washers to install the top cover in a detachable manner.

[0009] In some embodiments of this disclosure, the height of the side water outlets is lower than that of the top cover, and there are four side water outlets arranged symmetrically.

[0010] In some embodiments of this disclosure, the cross-section of the side outlet is square, circular, or fan-shaped.

[0011] In some embodiments of this disclosure, a limiting part is provided at the top of the hollow cylindrical structure.

[0012] In some embodiments of this disclosure, the straight-insertion water outlet is installed on an overflow pipe or an inlet / outlet pipe, and a buffer structure is installed at the corner of the water pipe. The buffer structure includes multiple springs, and the ends of the springs are fixedly connected to a receiving plate.

[0013] In some embodiments of this disclosure, an O-ring is provided between the base and the top cover.

[0014] In some embodiments of this disclosure, the inner wall of the side outlet is provided with a wear-resistant coating.

[0015] The beneficial effects of this utility model are as follows:

[0016] The unique side-outlet design allows water to flow along the bottom of the pool, stirring up dust and debris accumulated around the inlet and carrying it into the return pipe. This solves the problem of previous systems where the inlet and outlet faced upwards, leading to dust and debris buildup at the bottom and requiring a vacuum cleaner for cleaning. An adjustable pressure plate inside allows for adjusting the water flow. It can be directly bonded to 1.0MPA PVC water pipes without prior pre-installation; installation can be done after floor tiles are laid, saving time, increasing efficiency, and reducing difficulty. The top cover is removable for easy removal of large debris like hair. The top cover also features internal water flow channels for greater impact force and better cleaning results.

[0017] The design features a frustum-shaped base with a stepped top surface, ensuring precise installation with the top cover. The side outlets are angled at 30°~60° to optimize fluid dynamics. Four symmetrically distributed side outlets guarantee even water distribution. An innovative screw-plate adjustment mechanism achieves precise flow control. The gap between the adjustable plate and the return pipe can be precisely adjusted. A limit switch prevents over-adjustment, ensuring operational safety. A wear-resistant coating on the inner wall of the side outlets extends service life. An O-ring seal ensures leak-free operation over extended periods. Modular disassembly design reduces maintenance time. A removable top cover allows for real-time monitoring of the internal status. Standardized interface design ensures compatibility with existing piping systems. An expandable installation buffer structure reduces water flow impact noise. Attached Figure Description

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example 1

[0027] This example discloses a straight-insertion water inlet with a side outlet; see [link to relevant documentation]. Figures 1 to 7 ;

[0028] The device includes a base 1, a detachable top cover 2 on top of the base 1, multiple side outlets 3 on the side of the base 1, and a return water pipe 4 connected to the base 1 through the side outlets 3 to form a water flow channel. An annular support block 5 is provided on the inner wall of the return water pipe 4 to support an adjustable pressure plate 6. The diameter of the adjustable pressure plate 6 is smaller than the inner diameter of the return water pipe 4. An adjusting screw 7 is installed through the middle of the adjustable pressure plate 6. The adjusting screw 7 is installed in a hollow cylindrical structure 8. The hollow cylindrical structure 8 is fixed to the annular support block 5 by a connecting rod 9. The inner wall of the hollow cylindrical structure 8 is provided with a thread that fits the adjusting screw, so that the rotation of the adjusting screw 7 drives the lifting and lowering of the adjustable pressure plate 6.

[0029] The base 1 is a hollow frustum shape with a stepped top surface for mounting the top cover, and the sides are inclined at an angle of 30° to 60° to the horizontal plane.

[0030] Multiple bolt holes are evenly distributed around the base 1 along the circumference. Bolts 11 are installed in the bolt holes through elastic sealing washers, and the top cover 2 is installed in a detachable manner.

[0031] The height of the side outlet 3 is lower than that of the top cover 2, and there are 4 side outlets 3 arranged symmetrically.

[0032] The cross-section of the side outlet 3 is square, circular, or fan-shaped.

[0033] A limiting part is set at the top of the hollow columnar structure 8.

[0034] An O-ring is provided between the base 1 and the top cover 2.

[0035] The inner wall of the side outlet 3 is coated with a wear-resistant coating.

[0036] During the work process,

[0037] In the closed state, water will not enter the side outlet 3, and the entire overflow outlet is in standby mode. The adjustable pressure plate 6 is fixed in the initial position by the adjusting screw 7, at which point the return pipe 4 is closed. In the start state, water begins to flow into the return pipe 4 through the side outlet 3. Due to the design of the side outlet 3, the water flow can transition smoothly. When adjusting the flow rate, the operator can change the height position of the adjustable pressure plate 6 by rotating the adjusting screw 7: clockwise rotation: the pressure plate moves down, reducing the flow area of ​​the return water pipe 4 and reducing the overflow; counterclockwise rotation: the pressure plate moves up, increasing the flow area and increasing the overflow; the limiting part at the top of the hollow cylindrical structure 8 can prevent over-adjustment from causing damage to the mechanism; under stable working conditions, after the pressure plate is adjusted to the appropriate position, the water flows steadily through the annular gap between the side outlet 3 and the edge of the adjustable pressure plate 6. The wear-resistant ceramic coating 15 effectively resists the scouring of high-speed water flow, and the O-ring seal ensures the sealing of the device; when rapid drainage is required, the adjustable pressure plate 6 can be raised to the highest position to make the return water pipe 4 completely unobstructed; when complete closure is required, the pressure plate can be lowered to the lowest position to achieve the interception function. Example 2

[0038] The principle of this example is the same as that of Example 1, the specific difference being: see [link / reference] Figures 5 to 7 ;

[0039] A straight-insertion water outlet is installed on the overflow pipe 12. A buffer structure can be installed at the corner of the overflow pipe 12. The buffer structure includes multiple springs 13, and the ends of the springs 13 are fixedly connected to the receiving plate 10.

[0040] During operation, when water flows into the overflow pipe 12, the water comes into contact with the receiving plate 10, causing the spring 13 to deform and buffer the impact force of the water flow, preventing damage to the overflow pipe caused by prolonged water flow impact.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0042] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this application and their equivalents, this utility model also intends to include these modifications and variations.
