Description

Technical Field

[0001] This application relates to the field of drainer technology, specifically a spring-loaded drainer with anti-overflow function. Background Technology

[0002] In modern family life, pop-up drains have become an indispensable plumbing accessory in kitchens, bathrooms, and other areas. Pop-up drains control the flow of water by the up-and-down movement of a popping core, making them easy to operate and highly practical. They can conveniently fill the sink according to usage needs.

[0003] Currently, when water is stored in the pool using a bouncing drain device, the water level can easily rise continuously until it overflows when left unattended, requiring manual cleaning of the overflowing water. It does not have an overflow prevention function. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a spring-loaded drain with an anti-overflow function. This device allows for water storage in a pool without continuous human supervision. When the water level reaches a certain height, the spring-loaded drain automatically drains the water, preventing overflow due to a continuously rising water level. This solves the problem that current spring-loaded drains, when unattended, easily cause the water level to rise continuously until overflow, requiring manual cleaning of the overflowing water, thus lacking an anti-overflow function.

[0005] To achieve the goal of eliminating the need for continuous human supervision when filling a pool with a spring-loaded drain, and automatically draining the water when the water level reaches a certain height to prevent overflow due to a continuously rising water level, this application provides the following technical solution: a spring-loaded drain with an anti-overflow function, comprising a housing, the housing including a connecting cover, a water-stop cover at the water outlet in the middle of the connecting cover, an overflow hole penetrating vertically in the middle of the water-stop cover, and an overflow hole at the bottom of the water-stop cover. An overflow pipe is provided, and a spring is connected to the bottom of the overflow pipe. Multiple water outlets are arranged in a ring array on the outer surface of one end of the overflow pipe. A spring is provided at the bottom of the inner wall of the overflow pipe, and a connecting block is provided at one end of the spring. A first sealing ring is provided on the outer surface of the middle part of the connecting block. The first sealing ring is made of soft rubber. A second sealing ring is provided on the inner wall of the middle part of the overflow pipe. The second sealing ring is made of hard rubber. Multiple top rods are arranged in a ring array on the inner wall of the middle part of the overflow pipe through multiple fixing plates. The top rods are located below the first sealing ring.

[0006] With the above solution, when the pool is filled with water, the water in the pool will enter the overflow pipe through the overflow hole. The water in the pool will exert pressure on the connecting block and the first sealing ring. When the pressure of the water in the pool on the connecting block exceeds the elastic force of the spring, the connecting block and the first sealing ring will move downward. The push rod will push open the first sealing ring, thereby allowing the water in the pool to be discharged through the overflow pipe. This achieves the effect that when filling the pool with water using the spring-loaded drain device, no continuous manual monitoring is required. When the water level in the pool reaches a certain height, the spring-loaded drain device can automatically discharge the water in the pool, which can prevent the water from overflowing due to the continuous rise of the water level in the pool.

[0007] Furthermore, two limiting rods are provided on both sides of the bottom of the connecting block. The outer surface of the middle part of the two limiting rods is inserted into the inner wall of the middle part of the two limiting frames. The two limiting frames are set on both sides of the inner wall of the middle part of the overflow pipe by fixing rods.

[0008] The above solution uses two limiting rods at the bottom of the connecting block to slide within the inner walls of the two limiting frames, thus fixing the trajectory of the connecting block's movement and improving its stability during movement.

[0009] Furthermore, the outer surface of the end of the push rod near the first sealing ring is hemispherical.

[0010] The above solution allows the hemispherical shape of one end of the push rod to smoothly contact the first sealing ring, while preventing the push rod from scratching the first sealing ring and improving the service life of the first sealing ring.

[0011] Furthermore, the inner walls of the plurality of water outlets are each provided with a first filter screen.

[0012] The above solution protects the outlet by setting up the first filter screen, preventing debris attached to the water when draining from between the stop cover and the connecting cover from entering the overflow pipe through the outlet.

[0013] Furthermore, a second filter screen is provided on the inner wall of the overflow hole.

[0014] The above solution, by setting up a second filter screen, can prevent debris in the pool from entering the overflow pipe through the overflow hole, thus preventing it from affecting the operation of the components inside the overflow pipe.

[0015] Furthermore, the bottom of the connecting cover is provided with an internally threaded tube, and the inner wall of the middle part of the internally threaded tube is threadedly connected to the outer surface of one end of the interception net.

[0016] The above method allows the interceptor net to be removed from the connecting cover, making it easy to clean the net.

[0017] Furthermore, the outer surface of one end of the bouncing device is provided with an external thread, and the threaded outer surface of one end of the bouncing device is threadedly connected to the inner wall of the middle part of the bottom of the interception net.

[0018] The above solution allows the bouncing device to be removed from the interception net, facilitating the disassembly and cleaning of the entire drainage system.

[0019] Furthermore, the inner wall of the second sealing ring is funnel-shaped, and the shape of the inner wall of the second sealing ring is adapted to the shape of the first sealing ring.

[0020] The above scheme allows the first sealing ring to fit tightly against the second sealing ring, improving the sealing effect between the two. At the same time, the first sealing ring can slide downward inside the second sealing ring under the action of water pressure, thereby allowing the first sealing ring to be lifted up by the push rod.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This anti-overflow pop-up drainer works by allowing water to flow from the pool into the overflow pipe through the overflow hole when the pool is filled. The water in the pool exerts pressure on the connecting block and the first sealing ring. When the pressure of the water on the connecting block exceeds the spring force, the connecting block and the first sealing ring move downwards. The push rod pushes open the first sealing ring, allowing the water in the pool to be discharged through the overflow pipe. This achieves the effect of eliminating the need for continuous manual monitoring when filling the pool with water using the pop-up drainer. When the water level in the pool reaches a certain height, the pop-up drainer can automatically discharge the water in the pool, which can prevent water from overflowing due to the continuous rise of the water level in the pool.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 3 , Figure 4 and Figure 5 The overflow-proof bouncy drain in this embodiment includes a housing 1, which includes a connecting cover 101. A water-stop cover 2 is provided at the water outlet in the middle of the connecting cover 101. An overflow hole 3 is provided in the middle of the water-stop cover 2, which runs vertically through the water. An overflow pipe 4 is provided at the overflow hole 3 at the bottom of the water-stop cover 2. A bouncy device 15 is connected to the bottom of the overflow pipe 4. Multiple water outlets 5 are provided in a ring array on the outer surface of one end of the overflow pipe 4. A spring 6 is provided at the bottom of the inner wall of the overflow pipe 4. A connecting block 7 is provided at one end of the spring 6. A first sealing ring 8 is provided on the outer surface of the middle of the connecting block 7.

Multiple top rods 10 are provided in a ring array on the inner wall of the middle of the overflow pipe 4 through multiple fixing plates. The top rods 10 are located below the first sealing ring 8.

[0033] Please see Figure 4 and Figure 5 Two limiting rods 11 are provided on both sides of the bottom of the connecting block 7. The outer surface of the middle part of the two limiting rods 11 is inserted into the inner wall of the middle part of the two limiting frames 12. The two limiting frames 12 are set on both sides of the inner wall of the middle part of the overflow pipe 4 by fixing rods. The movement trajectory of the connecting block 7 can be fixed by the sliding of the two limiting rods 11 at the bottom of the connecting block 7 within the inner wall of the middle part of the two limiting frames 12, thereby improving the stability of the connecting block 7 when it moves.

[0034] Please see Figure 4 and Figure 5The outer surface of the end of the push rod 10 near the first sealing ring 8 is hemispherical. The hemispherical shape of the push rod 10 allows it to smoothly contact the first sealing ring 8, while preventing the push rod 10 from scratching the first sealing ring 8 and improving the service life of the first sealing ring 8.

[0035] Please see Figure 3 , Figure 4 and Figure 5 The inner walls of multiple water outlets 5 are equipped with first filter screens 13. The first filter screens 13 can protect the water outlets 5 and prevent the garbage attached to them when draining water from between the water stop cover 2 and the connecting cover 101 from entering the overflow pipe 4 through the water outlets 5.

[0036] Please see Figure 3 and Figure 5 The inner wall of the overflow hole 3 is provided with a second filter screen 14. The second filter screen 14 can prevent debris in the water tank from entering the overflow pipe 4 through the overflow hole 3, thus preventing it from affecting the operation of the components in the overflow pipe 4.

[0037] Please see Figure 2 , Figure 3 and Figure 6 The bottom of the connecting cover 101 is provided with an internally threaded tube 102. The inner wall of the middle part of the internally threaded tube 102 is threadedly connected to the outer surface of one end of the interception net 103, so that the interception net 103 can be removed from the connecting cover 101 and can be easily cleaned.

[0038] Please see Figure 2 , Figure 3 and Figure 6 The outer surface of one end of the bouncing device 15 is provided with an external thread, and the threaded outer surface of one end of the bouncing device 15 is threadedly connected to the inner wall of the middle part of the bottom of the intercepting net 103, so that the bouncing device 15 can be removed from the intercepting net 103, making it convenient to disassemble and clean the entire drain device.

[0039] Please see Figure 4 and Figure 5 The inner wall of the second sealing ring 9 is funnel-shaped, and the shape of the inner wall of the second sealing ring 9 is adapted to the shape of the first sealing ring 8, so that the first sealing ring 8 can fit tightly with the second sealing ring 9, improving the sealing effect of the first sealing ring 8 and the second sealing ring 9. At the same time, the first sealing ring 8 can slide downward inside the second sealing ring 9 under the action of water pressure, so that the first sealing ring 8 can be lifted by the push rod 10.

[0040] In this embodiment, the spring-loaded drain with anti-overflow function allows water to enter the overflow pipe 4 through the overflow hole 3 when the pool is filled with water. The water in the pool exerts pressure on the connecting block 7 and the first sealing ring 8. When the pressure of the water in the pool on the connecting block 7 exceeds the elastic force of the spring 6, the connecting block 7 and the first sealing ring 8 move downwards. The push rod 10 pushes open the first sealing ring 8, thereby allowing the water in the pool to be discharged through the overflow pipe 4. This achieves the effect of not requiring continuous human supervision when filling the pool with water using the spring-loaded drain. When the water level in the pool reaches a certain height, the spring-loaded drain can automatically discharge the water in the pool, which can prevent water from overflowing due to the continuous rise of the water level in the pool.

[0041] The working principle of the above embodiment is as follows: By pressing down on the water-stop cover 2, the overflow pipe 4 drives the spring device 15 to work, causing the water-stop cover 2 to open and close based on the connecting cover 101. This allows the water-stop cover 2 and the connecting cover 101 to drain and store water normally. When filling the pool with water, the water-stop cover 2 is closed, and the water in the pool enters the overflow pipe 4 through the overflow hole 3, generating a downward pressure on the connecting block 7 and the first sealing ring 8. At the same time, the elastic force of the spring 6 supports the connecting block 7. When the water level in the pool reaches a certain height, the pressure generated on the connecting block 7 and the first sealing ring 8 in the overflow pipe 4 exceeds the elastic force of the spring 6, causing the connecting block 7 to open and close. Block 7 moves the first sealing ring 8 downwards. As the first sealing ring 8 moves downwards, its bottom contacts the outer surface of one end of the top rod 10. The top rod 10 then lifts the edge of the first sealing ring 8, causing it to curl and deform. This releases the tight seal between the first sealing ring 8 and the second sealing ring 9. Water in the overflow pipe 4, connecting block 7 and the area above the first sealing ring 8, can flow downwards through the gap created by the curling of the first sealing ring 8 and the second sealing ring 9. The water is then discharged through the outlet 5 in conjunction with the intercepting net 103, causing the water in the pool to drain and lowering the water level to prevent overflow.
