Description

Technical Field

[0001] This utility model relates to drainers, and more particularly, to a drainer structure. Background Technology

[0002] Existing drain assembly structures, such as the Chinese utility model patent CN217150498U (Disclosure No. CN217150498U) describing an odor-proof housing and odor-proof spring-loaded plug, mainly include an outer shell comprising a cover portion and a peripheral wall portion. The cover portion is located above the peripheral wall portion and has an opening in its center. An odor-proof housing is located below the peripheral wall portion, and this housing has a water outlet that communicates with the opening. A cover plate is rotatably mounted at the water outlet, and a torsion spring is located at the pivot between the cover plate and the odor-proof housing. The torsion spring drives the cover plate to rotate and fit against the water outlet, thus achieving the odor-proof function at the lower end. A filter frame is also installed inside the outer shell, with drainage holes. A spring-loaded portion is installed in the center of the filter frame, and a press-down cover is installed above the spring-loaded portion. By pressing the press-down cover, the spring-loaded portion can control the press-down cover to rise or fall.

[0003] The actual drainage action of the above-mentioned drain is as follows: the pop-up part will pop up the press cover, and the water flow will pass through the opening, the drain hole and the outlet in sequence along the cover. During this process, if there are debris such as hair or debris mixed in the water flow, the debris will be filtered into the filter frame.

[0004] Over time, biofilm will form on the inner wall of the outer casing of the aforementioned type of drainer. This biofilm has strong adhesion and is difficult to remove with regular rinsing. A gap is left between the outer wall of the filter frame and the inner wall of the outer casing to facilitate the placement and removal of the filter frame. Similarly, we can see that the drainage holes on the filter frame are horizontally arranged. This means that the drainage speed of the entire drainer is determined by the water passage gap between the outer wall of the filter frame and the inner wall of the outer casing. However, as the thickness of the biofilm increases, it directly reduces the water passage gap between the outer wall of the filter frame and the inner wall of the outer casing, affecting the final drainage speed and shortening the overall lifespan of the drainer. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a drain device structure that can maintain the drainage speed for a long time and effectively extend its service life.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A drain assembly structure includes a drain pipe with an inlet and an outlet at both ends, and a debris removal section. The debris removal section includes a first debris removal component and a second debris removal component, with the end of the first debris removal component rotatably connected to the second debris removal component. The second impurity removal component is provided with a second rotary drive component, and the inner wall of the drain pipe is provided with a first rotary drive component; When the impurity removal part is lifted up and down, the first rotary drive member and the second rotary drive member come into contact with each other, and the second impurity removal member rotates circumferentially.

[0007] Through the above technical solution, during the lifting and lowering of the debris removal section, the first and second rotating drive components cooperate to drive the second debris removal component to rotate circumferentially. The rotating second debris removal component can scrape off the biological sludge adhering to the inner wall of the drain pipe, preventing the sludge from continuously thickening and compressing the water flow area inside the pipe. This helps maintain a relatively stable drainage path in the long term and alleviates the problem of slowing down drainage speed over time. Simultaneously, the rotating debris removal section has a better collection effect on debris, and debris is less likely to scatter during cleaning, thus extending the overall effective service life of the drain assembly.

[0008] Preferably, the first rotary drive component includes a spiral groove located on the inner wall of the drain pipe; The second rotary drive includes a second impurity removal plate located on the second impurity removal component; When the impurity removal section is lifted up and down, the end of the second impurity removal plate abuts and engages with the spiral groove.

[0009] The above technical solution, employing a structure that combines a spiral groove with a second cleaning plate, eliminates the need for additional power components. A simple lifting motion allows the cleaning plate to naturally rotate along the spiral groove, resulting in a simple and reliable structure. Furthermore, the spiral groove itself can serve as part of the water passage. As the end of the second cleaning plate moves along the groove wall, it directly cleans accumulated dirt within the groove, reducing the impact of sludge buildup on water flow.

[0010] Preferably, there are two or more spiral grooves, and the second impurity removal plate is matched with the spiral groove in a one-to-one correspondence.

[0011] By using the above technical solution, two or more spiral grooves are set up and correspond one-to-one with the second impurity removal plate. During the lifting process, the rotation of the second impurity removal component is more stable and the circumferential force is more uniform. At the same time, the multi-point contact with the pipe wall provides a wider coverage of the inner wall cleaning, which can more thoroughly clean the sludge in all parts of the pipe wall and help maintain the stability of the overall water flow area.

[0012] Preferably, the spiral groove extends to the end face of the water inlet.

[0013] With the above technical solution, the spiral groove extends to the end face of the inlet, allowing the second debris removal plate to move to the vicinity of the inlet. This also helps to clean the areas around the inlet that are prone to accumulating dirt, reducing the obstruction of water flow caused by the accumulation of debris and sludge at the inlet. In addition, it also makes it easier to install the second debris removal plate into the spiral groove.

[0014] Preferably, the second impurity removal plate is bent on the side facing the outlet to form a guide plate; The direction of water flow after impacting the guide vane is the same as the direction of water flow along the spiral groove.

[0015] With the above technical solution, when the water flows down from the inlet, it will hit the guide plate. The guided water can form a swirling flow along the spiral groove, which has a stronger scouring effect on the pipe wall and can also slow down the adhesion speed of the sludge on the pipe wall to a certain extent, thereby increasing the drainage speed.

[0016] Preferably, it also includes a cover, on which a connecting groove is provided through, the end of the drain pipe is connected to the connecting groove, and the water inlet is connected to the connecting groove.

[0017] With the above technical solution, the cover can be supported on the end face of the drain, which facilitates the positioning and installation of the entire drain; the connecting groove is connected to the inlet, which can play a preliminary role in converging the incoming water flow, allowing the water to enter the drain pipe more concentratedly.

[0018] Preferably, the wall of the connecting groove is provided with an extension edge, and the end of the drain pipe near the water inlet is turned outward with a flange, which is installed against the extension edge.

[0019] With the above technical solution, the drain pipe is installed by flanging against the extension edge, which makes positioning convenient during assembly, makes the connection between the drain pipe and the cover more stable, and also reduces the accumulation of dirt in the gaps at the joint.

[0020] Preferably, the extension edge is provided with an installation notch, and the outer wall of the drain pipe is provided with an installation protrusion, the installation protrusion and the installation notch cooperating with each other.

[0021] Through the above technical solution, after the installation protrusion and the installation notch engage with each other, the circumferential relative rotation between the drain pipe and the cover can be restricted, ensuring the stability of the spiral groove inside the drain pipe and the relative position of the cover, and also improving the overall assembly firmness.

[0022] Preferably, the outer wall of the drain pipe is provided with a spiral wall, and the protrusions of the spiral wall form the mounting protrusion.

[0023] The above technical solution utilizes the spiral structure of the pipe wall itself to directly form the installation protrusion, eliminating the need for additional protrusion components and resulting in a stronger overall structure. At the same time, the spiral pipe wall also enhances the structural strength of the drain pipe itself, making it easier to align with the notch and screw it in during installation.

[0024] Preferably, the cover is provided with an inclined drainage groove, and the inclined direction of the inclined drainage groove is consistent with the rotation direction of the spiral groove.

[0025] Through the above technical solution, the inclined drainage channel on the cover can guide the water flow on the platform into the drain pipe along the swirling direction, which corresponds to the swirling direction of the spiral groove inside the pipe, making the water swirling effect smoother, improving the flushing force of the water flow, and also helping to reduce the accumulation of debris at the cover.

[0026] Preferably, it also includes an odor-proof closing valve, which is installed at the water outlet.

[0027] The above technical solution involves installing an odor-proof closing valve at the water outlet, which can seal the outlet when there is no drainage, preventing odors from the sewer pipe from flowing back into the room, thus meeting both drainage and odor prevention needs.

[0028] Preferably, a limiting protrusion is provided on the inner wall of the drain pipe, the limiting protrusion is located on the side near the water outlet, and the second impurity removal plate abuts against the limiting protrusion.

[0029] Through the above technical solution, the limiting protrusion can block the downward movement of the second impurity removal part, preventing the impurity removal part from falling excessively out of the mating position, ensuring that each lifting can stably enter the specified stroke of the spiral groove mating, and also maintaining the predetermined installation position of the impurity removal part in the pipe.

[0030] Preferably, the first rotary drive component includes a spiral protrusion located on the inner wall of the drain pipe; The second rotary drive includes a second impurity removal plate located on the second impurity removal component. The second impurity removal plate has a mating groove that cooperates with the spiral protrusion. The end of the second impurity removal plate abuts against the inner wall of the drain pipe.

[0031] By employing the above technical solution, the combination of spiral protrusions and mating grooves can also drive the second cleaning component to rotate when the cleaning part is lifted, thus achieving the effect of cleaning the pipe wall. In this structure, the end of the second cleaning plate directly abuts the pipe wall, providing more thorough cleaning contact with the flat inner wall and offering another way to achieve rotational drive, which can be adapted to different processing and usage scenarios.

[0034] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0035] Example 1: A drain assembly structure, see [link / reference] Figure 4 It includes a drain pipe 1, with an inlet 2 at the upper end and an outlet 3 at the lower end.

[0036] A first rotary drive component 6 is provided on the inner wall of the drain pipe 1. The first rotary drive component 6 includes a spiral groove 7 located on the inner wall of the drain pipe 1. The number of spiral grooves 7 is two or more, and in this embodiment, the number of spiral grooves 7 is six. The ends of all spiral grooves 7 extend to the end face of the water inlet 2.

[0037] It is also provided with a cleaning part 4, which includes a first cleaning component 41 and a second cleaning component 42. The end of the first cleaning component 41 is rotatably connected to the second cleaning component 42.

[0038] A second rotary drive member 5 is provided on the second impurity removal member 42. The second rotary drive member 5 includes second impurity removal plates 51 located on the second impurity removal member 42. The number of second impurity removal plates 51 is the same as the number of spiral grooves 7, and the second impurity removal plates 51 are matched one-to-one with the spiral grooves 7. In this embodiment, the number of second impurity removal plates 51 is also 6.

[0039] When the impurity removal part 4 is lifted up and down, the end of the second impurity removal piece 51 abuts and engages with the spiral groove 7, and the second impurity removal part 42 rotates circumferentially.

[0040] See Figure 3 A guide vane 511 is formed by bending the second impurity removal plate 51 on the side wall near the outlet 3. The direction of water flow after the water flowing into the inlet 2 hits the guide vane 511 is consistent with the direction of water flow along the spiral groove 7.

[0041] It also includes a cover 8, with a connecting groove 9 extending through the middle of the cover 8. The connecting groove 9 has an extension edge 10 on its wall, thus forming a stepped surface on the wall of the connecting groove 9. The end of the drain pipe 1 near the inlet 2 has an outwardly turned flange 12. After the drain pipe 1 passes through the connecting groove 9, the flange 12 abuts against the stepped surface formed by the extension edge 10. The entire end of the drain pipe 1 is connected to the connecting groove 9, and the inlet 2 communicates with the connecting groove 9.

[0042] The cover 8 is provided with an inclined drainage groove 15, the inclined direction of which is consistent with the rotation direction of the spiral groove 7.

[0043] An installation notch 11 is provided on the extension edge 10, and a spiral pipe wall 14 is provided on the outer pipe wall of the drain pipe 1. The protruding ridges of the spiral pipe wall 14 form an installation protrusion 13. The installation protrusion 13 and the installation notch 11 cooperate with each other.

[0044] A limiting protrusion 17 is provided on the inner wall of the drain pipe 1. In this embodiment, the limiting protrusion 17 is an annular protrusion. The limiting protrusion 17 is located on the side close to the outlet 3. The second impurity removal plate 51 abuts against the limiting protrusion 17, thereby positioning the second impurity removal plate 51.

[0045] In addition, it also includes an odor-proof closing valve 16, which is installed at the water outlet 3.

[0046] Actual drainage process: First, insert the entire drain pipe 1 of the drain assembly into the ground drain outlet. The cover 8 rests against the opening of the ground drain outlet. Water on the ground flows sequentially through the inclined drainage channel 15, the inlet 2, the spiral channel 7, and the outlet 3, opening the anti-odor closing valve 16, allowing water to flow out smoothly. During this water flow process, the water on the ground is guided by the inclined drainage channel 15, the spiral channel 7, and the guide plate 511, creating a swirling vortex effect. When the water contains impurities, such as hair, these impurities are blocked by the second impurity removal plate 51.

[0047] It is worth mentioning that when there is a large amount of water on the ground, the water entering the drain pipe 1 is guided by the inclined diversion channel 15, the spiral channel 7, and the guide plate 511, and the water flow will generate a stronger rotating vortex effect, resulting in better drainage.

[0048] (2) Actual cleaning process: The operator holds the first cleaning component 41 and applies upward force. The second cleaning plate 51 can move along the spiral groove 7. The second cleaning plate 51 drives the second cleaning component 42 to rotate. At this time, the impurities on the second cleaning plate 51 will be subjected to circumferential winding force, making it difficult for them to accidentally fall off the second cleaning plate 51. The end of the second cleaning plate 51 can also clean the dirt attached to the spiral groove 7.

[0049] Example 2: The difference from Example 1 is that the structures of the first rotary drive member 6 and the second rotary drive member 5 are changed.

[0050] That is, the first rotary drive 6 includes a spiral protrusion 18 located on the inner wall of the drain pipe 1.

[0051] The second rotary drive 5 includes a second debris removal plate 51 located on the second debris removal member 42. The second debris removal plate 51 is provided with a mating groove 19 that cooperates with the spiral protrusion 18. The end of the second debris removal plate 51 abuts against the inner wall of the drain pipe 1.

[0052] When the cleaning part 4 is pulled up and down, the spiral protrusion 18 and the mating groove 19 cooperate with each other, the second cleaning part 42 rotates circumferentially, and the end of the second cleaning plate 51 directly touches the pipe wall, making more thorough cleaning contact with the flat inner wall. The cleaning part 4 in the rotating state has a better effect on collecting debris, and the debris is not easy to scatter when it is taken out for cleaning, which can extend the effective service life of the drainer.

[0053] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
