Description

Technical Field

[0001] This application belongs to the field of regulator manufacturing technology, specifically a rotary water flow regulator. Background Technology

[0002] A flow regulator is a drainage device installed in places such as washbasins, primarily used for drainage to control the flow rate or opening / closing of the drain. Common types include pop-up, flap, and cover types. A pop-up flow regulator controls the opening and closing of the drain outlet by pressing; a spring supports the drain outlet, and external pressure is transmitted to the spring, causing it to expand and contract, thus opening and closing the drain outlet. A flap flow regulator uses external force to flip a water-blocking plate downwards, creating different flip angles to control the flow rate and opening / closing. A cover flow regulator uses an independent cover that fits over the drain outlet to control its opening and closing.

[0003] The spring-loaded flow regulator has two main drawbacks: firstly, its complex structure and reliance on springs for operation mean that the entire device will fail when the springs tire or even fail; secondly, it is prone to accumulating dirt and requires regular cleaning. The flap-type flow regulator requires precise dimensional matching between the baffle plate and the base, and may experience incomplete closure after prolonged use. The cover-type flow regulator only has two states: covered and uncovered, with no intermediate state, making it impossible to achieve gradient adjustment of drainage flow. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies by designing a rotary water flow regulator that uses a combination of a first filter plate and a second filter plate. This regulator can prevent incomplete closure while simultaneously filtering water, thus solving the problems of current flow regulators being complex in structure, unable to filter, and prone to incomplete closure after prolonged use.

[0005] To achieve the above objectives, the following technical solution is adopted: A rotary water flow regulator includes a base, a first filter plate, and a second filter plate. The base has an upward-opening concave cavity, which is cylindrical. The first and second filter plates are coaxially arranged within the concave cavity. The first filter plate is coaxially and sealed within the concave cavity. An outlet is provided at the bottom of the concave cavity. A rotating shaft is dynamically sealed on the first filter plate. The second filter plate is coaxially and fixedly mounted on the rotating shaft. The second filter plate has a plurality of second holes arranged in a circular array around the rotating shaft. The first filter plate has a plurality of first holes arranged in a circular array around the rotating shaft. The lower surface of the second filter plate is slidably and sealedly connected to the upper surface of the first filter plate. The second filter plate has a first position where it rotates around the rotating shaft to completely block the first holes, and a second position where it rotates around the rotating shaft to completely expose the first holes.

[0006] Preferably, both the first and second filter plates are made of ductile iron or stainless steel.

[0007] Preferably, the first hole and the second hole have the same shape and size.

[0008] Preferably, the first filter plate has a plurality of first holes arranged in an equidistant array around the rotation axis, and the second filter plate has a plurality of second holes arranged in an equidistant array around the rotation axis.

[0009] Preferably, the first hole on the first filter plate is fan-shaped.

[0010] Preferably, a drain pipe is provided on the base outside the cavity, and one end of the drain pipe is connected to the cavity through a water outlet.

[0011] Preferably, the drain pipe is integrally formed with the base.

[0012] Preferably, the inner circumferential surface of the outlet is provided with an internal thread, and one end of the drain pipe is provided with an external thread that mates with the internal thread.

[0013] Compared with the prior art, the beneficial effects of this application are: This application employs a combination of a first filter plate and a second filter plate to design a rotary water flow regulator that can prevent incomplete closure while simultaneously filtering water. This solves the problems of current flow regulators, such as complex structures, inability to filter water, and the tendency for incomplete closure after prolonged use. Attached Figure Description

[0016] Reference Figure 1 - Figure 4A rotary water flow regulator includes a base 1, a first filter plate 2, and a second filter plate 3. The base 1 has an upward-opening concave cavity 4, which is cylindrical. The first filter plate 2 and the second filter plate 3 are coaxially arranged inside the concave cavity 4. The first filter plate 2 is coaxially and sealed within the concave cavity 4. The bottom of the concave cavity 4 has a water outlet 5. A rotating shaft 6 is dynamically sealed on the first filter plate 2. The second filter plate 3 is coaxially and fixedly arranged on the rotating shaft 6. The second filter plate 3 has a plurality of second holes 7 arranged in a circular array around the rotating shaft 6. The first filter plate 2 has a plurality of first holes 8 arranged in a circular array around the rotating shaft 6. The lower surface of the second filter plate 3 is slidably and sealedly connected to the upper surface of the first filter plate 2. The second filter plate 3 has a first position where it rotates around the rotating shaft 6 to completely block the first holes 8, and a second position where it rotates around the rotating shaft 6 to completely expose the first holes 8.

[0017] In this embodiment, the first filter plate 2, the second filter plate 3, and the base 1 work together to perform their functions. The first filter plate 2 and the second filter plate 3 are the core components for water flow regulation. By rotating the second filter plate 3, their relative movement is adjusted, controlling the misalignment between the first hole 8 on the first filter plate 2 and the second hole 7 on the second filter plate 3, thus controlling the water flow rate and even the opening and closing of the drain outlet. The base supports the first filter plate 2 and the second filter plate 3 upwards. Its opening size and shape are the same as those of the first filter plate 2 and the second filter plate 3. A wing ring 10 is provided on the outer edge of the opening of the cavity 4 on the base 1 for easy removal. In use, the base 1 is connected downwards to the drain pipe 9 through the outlet 5. The drain pipe 9 is connected below the base 1 to drain the water flowing through the first filter plate 2 and the second filter plate 3.

[0018] As a preferred method, the first filter plate 2 and the second filter plate 3 are made of ductile iron or stainless steel, because ductile iron or stainless steel has high rigidity and mechanical strength, is corrosion resistant, and is not easy to rust.

[0019] As a preferred embodiment, the first hole 8 and the second hole 7 are of the same shape and size. A plurality of the first holes 8 are arranged in an equidistant array around the rotation axis 6 on the first filter plate 2, and a plurality of the second holes 7 are arranged in an equidistant array around the rotation axis 6 on the second filter plate 3. The shape of the first hole 8 on the first filter plate 2 is fan-shaped.

[0020] The first filter plate 2 and the second filter plate 3 are typically divided into 16 equal fan-shaped sections, forming a first hole 8 and a second hole 7. Solid fan-shaped sections and empty fan-shaped sections (pores) are distributed alternately, each accounting for half of the total. A circular rotating shaft 6 is located at the center. The first and second filter plates 2 and 3, with their certain thickness and mass, are better able to resist larger water flow impacts and are less prone to displacement. During use, the second filter plate 3 is rotated. When the second filter plate 3 completely overlaps with the solid fan-shaped section of the first filter plate 2 (the first hole 8 of the first filter plate 2 and the second hole 7 of the second filter plate 3 also completely overlap), the flow rate is at its maximum, and the water passage capacity is at its greatest. When the solid fan-shaped section of the second filter plate 3 partially overlaps with the solid fan-shaped section of the first filter plate 2 (the first hole 8 and the second hole 7 also partially overlap), the porosity gradually decreases, and the water passage capacity gradually diminishes. When the solid fan-shaped section of the second filter plate 3 completely separates from the solid fan-shaped section of the first filter plate 2 (the first hole 8 and the second hole 7 also completely separate), the porosity is zero, the water flow is completely blocked, and drainage stops.

[0021] As a preferred embodiment, a drain pipe 9 is provided on the base 1 outside the recess 4, and one end of the drain pipe 9 is connected to the recess 4 through a water outlet 5. By directly providing the drain pipe 9, the drain pipe 9 and the base 1 become a single unit, which facilitates storage and transportation and reduces subsequent assembly time.

[0022] As a preferred embodiment, the drain pipe 9 is integrally formed with the base 1. This provides greater stability.

[0023] As a preferred embodiment, the inner circumferential surface of the outlet 5 is provided with an internal thread, and one end of the drain pipe 9 is provided with an external thread that mates with the internal thread. This arrangement facilitates the removal of the drain pipe 9 from the base 1.
