Description

Technical Field

[0001] This utility model belongs to the field of drain device technology, and in particular relates to a concealed pop-up drain device. Background Technology

[0002] In daily life, washbasins are common sanitary ware, and the ease of use and difficulty of cleaning and maintenance of their drains are of great concern. Traditional washbasins have a drain outlet at the bottom of the basin, along with a drain assembly. However, when the washbasin needs to drain water, users have to put their hands into the sewage to turn on the drain, which is both unhygienic and extremely inconvenient, resulting in a poor user experience.

[0003] To address the inconvenience of traditional drainers, for example, utility model patent CN219060219U discloses an integrated pop-up drainer for concealed drain outlets. This drainer includes a drainer housing and a pop-up body. The drainer housing consists of a base and an upwardly extending limiting cylinder. The lower part of the limiting cylinder has several drain outlets. The pop-up body includes a pop-up core and a connecting part. The pop-up core is detachably installed below the connecting part. A limiting device is provided on the outer surface of the connecting part. The pop-up body is mounted on the drainer housing.

[0004] While this type of integrated pop-up drain improves operational issues to some extent, it still reveals significant drawbacks in actual use. These pop-up drains are typically installed in the recesses of washbasins, which, due to their structural characteristics, are prone to accumulating dirt and grime. Furthermore, the confined space of these recesses means that cleaning requires disassembling the drain, a cumbersome and complex process that not only consumes considerable time and effort but also risks damaging components and shortening its lifespan due to frequent disassembly.

[0005] Based on this, the present invention provides a novel concealed bouncing water device to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a concealed pop-up drain. During the drainage process, the water flow naturally drives the cleaning component to rotate, thoroughly cleaning the groove in the ceramic basin that houses the drain and keeping the groove clean and tidy. At the same time, when deep cleaning is required, other structures above the pop-up core and outside the mounting cylinder can be removed from the pop-up core. At this time, the cleaning component can become an independent cleaning tool, and deep cleaning of the groove can be performed directly without the need for other auxiliary cleaning tools.

[0007] The present invention adopts the following technical solution: a concealed bouncing drain device, which includes an installation cylinder, a first connecting cylinder, a second connecting cylinder and a push cylinder arranged sequentially from bottom to top along the axial direction;

[0008] A bouncing core is fixedly installed inside the mounting cylinder;

[0010] The second connecting cylinder is connected to the end of the first connecting cylinder away from the mounting cylinder, and the mounting height of the second connecting cylinder on the first connecting cylinder is adjustable;

[0011] The push cylinder is fixedly connected to the end of the second connecting cylinder away from the first connecting cylinder.

[0012] Furthermore, a sealing ring is fitted onto the outer peripheral wall of the first connecting cylinder near the end of the mounting cylinder, and the sealing ring is adapted to the reserved gap between the mounting cylinder and the first connecting cylinder.

[0013] Furthermore, a ceramic plate is fixedly installed at the end of the push cylinder away from the second connecting cylinder.

[0014] Furthermore, at least one overflow hole is provided on the peripheral wall of the end of the push cylinder away from the second connecting cylinder.

[0015] Furthermore, a guide ring is fitted onto the peripheral wall of the end of the push cylinder away from the second connecting cylinder. The guide ring is fixedly connected to the push cylinder through multiple guide brackets, and the installation position of the guide ring is below the overflow hole.

[0016] Furthermore, a fixing sleeve is fixedly installed inside the first connecting cylinder. One end of the fixing sleeve is connected to the bouncing end of the bouncing core, and the other end of the fixing sleeve is connected to the end of the first connecting cylinder away from the mounting cylinder through an adjustment component.

[0017] Furthermore, the adjustment assembly includes a receiving cylinder, a spring, and a push rod;

[0018] The receiving cylinder is disposed on the other end face of the fixed sleeve, and the bottom end of the receiving cylinder is fixedly connected to the other end of the fixed sleeve; the spring is installed inside the receiving cylinder, and one end of the spring is connected to the bottom end of the receiving cylinder.

[0019] The bottom end of the push rod extends into the receiving cylinder and is connected to the other end of the spring, and the push rod is fixedly installed inside the second connecting cylinder;

[0020] Two sliders are symmetrically arranged on the outer peripheral wall of the second connecting cylinder, and two semi-circular sliding plates are symmetrically fixed to the inner peripheral wall of the first connecting cylinder. Multiple spaced grooves are opened parallel to each other along the arc direction on the sliding plates. Each groove has a fixed groove at the bottom. The fixed groove communicates with the groove to form an L-shaped sliding track. The slider is slidably installed in the L-shaped sliding track. When the slider slides into the fixed groove, the second connecting cylinder is fixedly installed on the first connecting cylinder.

[0021] Furthermore, the side wall of the container cylinder is provided with at least one rectangular hydrophobic hole.

[0022] Furthermore, the cleaning component includes:

[0023] A rotating ring is sleeved and installed on the outer peripheral wall of the first connecting cylinder near the mounting cylinder, and is rotatably connected to the outer peripheral wall of the first connecting cylinder.

[0024] A cleaning blade is fixedly connected to the rotating ring, and the cleaning blade is composed of three surfaces: a straight surface, an arc surface, and a curved surface.

[0025] A brush, the brush being disposed on the lower surface of the cleaning blade;

[0026] A scraper is fixedly installed on the upper surface of the cleaning blade and located at the arc surface, and the arc of the scraper is the same as the arc of the arc surface.

[0027] A rotating blade is fixedly installed on the upper surface of the cleaning blade and located at the curved surface, and the curvature of the rotating blade is the same as that of the curved surface.

[0028] Furthermore, a sponge sheet is provided on the outer wall surface of the scraper on the side away from the rotating ring;

[0029] And / or the scraper is provided with at least one water passage hole.

[0030] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0031] 1) The concealed pop-up drain device of this utility model is very easy to operate. The user only needs to press the push-button cylinder, which drives the second connecting cylinder. The second connecting cylinder, through its connection with the first connecting cylinder, transmits force to the pop-up end of the pop-up core, causing the pop-up core to move and realize the opening and closing of the drain channel, thereby controlling the drainage and water stop of the drain device.

[0032] During drainage, the water flow naturally rotates the cleaning component, thoroughly cleaning the recessed area of ​​the ceramic basin where the drain assembly is located, keeping the recess clean and tidy. Notably, for deep cleaning, the other structures above the spring-loaded core and outside the mounting sleeve can be detached from the spring-loaded core. In this case, the cleaning component becomes an independent cleaning tool, allowing for direct deep cleaning of the recessed area without the need for other auxiliary tools. Therefore, the cleaning component effectively cleans the area where the ceramic basin contacts the drain assembly, effectively preventing dirt buildup, maintaining the cleanliness and hygiene of the ceramic basin, and extending its lifespan.

[0033] Furthermore, the installation height of the second connecting tube on the first connecting tube of this drain assembly is flexibly adjustable, a feature that allows it to adapt to various sizes of sinks or containers. Whether it's a shallow or deep sink, it can easily handle it, greatly enhancing the versatility of the drain assembly. This not only reduces installation difficulty but also eliminates the need for custom-made drain assemblies for installation environments of different depths, effectively saving costs.

[0034] 2) The fixed groove in the L-shaped sliding track provides a stable positioning point for the slider. When the slider slides into the fixed groove, the second connecting cylinder is firmly fixed to the first connecting cylinder with the assistance of the spring force, preventing loosening or displacement during use and ensuring the stability of the overall structure of the drain assembly. At the same time, the spring acts as a buffer during adjustment, reducing the impact force during adjustment, avoiding rigid collisions between components, extending the service life of each component of the drain assembly, and making the adjustment process smoother and more comfortable.

[0035] 3) The brush and scraper work simultaneously, cleaning the bottom and sides of the groove separately, greatly improving cleaning efficiency and effectively removing various dirt and impurities from the ceramic basin's grooves. At the same time, the rotating blades, driven by the force of water flow, achieve a degree of automatic cleaning, eliminating the need for manual operation and providing a more convenient and labor-saving user experience. Furthermore, the curvature of the scraper matches the arc surface of the cleaning blades, allowing the cleaning components to better conform to the shape of the ceramic basin's grooves during operation, ensuring thorough cleaning without blind spots and guaranteeing effective cleaning results.

Detailed Implementation

[0047] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] The following is in conjunction with the appendix Figure 1 To be continued Figure 9 The present invention will be described in detail with reference to specific embodiments:

[0049] like Figure 1-9 As shown, this utility model provides a concealed bouncing drain device, including an installation cylinder 1, a first connecting cylinder 2, a second connecting cylinder 3, and a push-button cylinder 4 arranged sequentially from bottom to top along the axial direction; at the same time, in this embodiment, the installation cylinder 1, the first connecting cylinder 2, the second connecting cylinder 3, and the push-button cylinder 4 are arranged coaxially.

[0050] The mounting cylinder 1 is a cylindrical structure with openings at both ends, and a spring-loaded core 10 is fixedly installed inside it. In use, the mounting cylinder 1 is fixedly installed on the ceramic basin to achieve the fixed installation of the concealed spring-loaded drain.

[0051] The first connecting cylinder 2 is also a cylindrical structure with openings at both ends. Its end near the mounting cylinder 1 is connected to the bouncing end of the bouncing core 10, and a cleaning component 6 is sleeved on the outer peripheral wall of the first connecting cylinder 2 near the mounting cylinder 1.

[0052] The second connecting cylinder 3 is also a cylindrical structure with openings at both ends. It is connected to the end of the first connecting cylinder 2 away from the mounting cylinder 1, and the mounting height of the second connecting cylinder 3 on the first connecting cylinder 2 is adjustable.

[0053] The push cylinder 4 is fixedly connected to the end of the second connecting cylinder 3 away from the first connecting cylinder 2.

[0054] The concealed pop-up drain device of this utility model is very easy to operate. The user only needs to press the actuating cylinder 4, which drives the second connecting cylinder 3. The second connecting cylinder 3, through its connection with the first connecting cylinder 2, transmits force to the popping end of the popping core 10, causing the popping core 10 to move and realize the opening and closing of the drain channel, thereby controlling the drainage and water stop of the drain device.

[0055] During drainage, the water flow naturally rotates the cleaning component 6, thoroughly cleaning the recessed area of ​​the ceramic basin that houses the drain, maintaining its cleanliness. Notably, for deep cleaning, the other structures above the spring-loaded core 10 and outside the mounting cylinder 1 can be detached from the spring-loaded core 10. In this case, the cleaning component 6 becomes an independent cleaning tool, allowing for direct deep cleaning of the recessed area without the need for other auxiliary tools. Therefore, the cleaning component 6 effectively cleans the area where the ceramic basin contacts the drain, preventing dirt buildup, maintaining the cleanliness of the ceramic basin, and extending its lifespan.

[0056] Furthermore, the installation height of the second connecting cylinder 3 on the first connecting cylinder 2 of this drain assembly is flexibly adjustable, a feature that allows it to adapt to various sizes of sinks or containers. Whether it's a shallow or deep sink, it can easily handle it, greatly enhancing the versatility of the drain assembly. This not only reduces installation difficulty but also eliminates the need for custom-made drain assemblies for installation environments of different depths, effectively saving costs.

[0057] Furthermore, in some specific embodiments, such as Figure 6 , 7 As shown, the bouncing core 10 is fixedly installed inside the mounting cylinder 1 by multiple bouncing brackets 11 evenly arranged on its outer periphery. That is, one end of the bouncing bracket 11 is fixedly connected to the inner wall of the mounting cylinder 1, and the other end is connected to the outer wall of the bouncing core 10. In this embodiment, three bouncing brackets 11 are provided and evenly distributed along the circumference of the inner wall of the mounting cylinder 1, fixing the bouncing core 10 at the position of the central axis of the mounting cylinder 1.

[0058] A fixing sleeve 20 is fixedly installed inside the first connecting cylinder 2. The fixing sleeve 20 is fixedly installed inside the first connecting cylinder 2 by multiple fixing brackets 21 evenly arranged on its outer periphery. That is, one end of the fixing bracket 21 is connected to the inner wall of the first connecting cylinder 2, and the other end is connected to the outer wall of the fixing sleeve 20. In this embodiment, three fixing brackets 21 are provided and are evenly distributed along the circumference of the inner wall of the first connecting cylinder 2, fixing the fixing sleeve 20 at the position of the central axis of the first connecting cylinder 2.

[0059] Meanwhile, an internal thread is provided at the end of the fixed sleeve 20 that connects to the spring end of the spring core 10, and an external thread is provided at the end of the spring core 10 near the first connecting cylinder 2. The external thread fits onto the internal thread, realizing a threaded connection between the fixed sleeve 20 and the spring core 10. The threaded connection method makes the connection between the fixed sleeve 20 and the spring core 10 tight and reliable. During the force transmission process, it can effectively avoid problems such as poor force transmission or component detachment caused by loose connection, ensuring the accuracy and stability of the drain switch operation. When it is necessary to remove other structures above the spring core 10 and outside the mounting cylinder 1 from the spring core 10, simply rotate in the opposite direction to separate the external thread from the internal thread to complete the disassembly operation. No complicated tools or operating procedures are required, reducing maintenance costs and time costs, and improving the maintainability of the drain.

[0060] Furthermore, in some specific embodiments, such as Figure 2 , 4As shown in Figures 6 and 7, the outer diameter of the first connecting cylinder 2 is slightly smaller than the inner diameter of the mounting cylinder 1, thus forming a reserved gap between the mounting cylinder 1 and the first connecting cylinder 2. Correspondingly, a sealing ring 22 is fitted onto the outer peripheral wall of the first connecting cylinder 2 near the end of the mounting cylinder 1. The sealing ring 22 is adapted to the reserved gap between the mounting cylinder 1 and the first connecting cylinder 2 and is used to seal the reserved gap between the mounting cylinder 1 and the first connecting cylinder 2.

[0061] When the bouncing core 10 is not bouncing, the sealing ring 22 is tightly fitted at the reserved gap between the mounting cylinder 1 and the first connecting cylinder 2, effectively preventing water flow and achieving the water-stopping function. When the bouncing core 10 is subjected to external force and bounces, the first connecting cylinder 2 will move with it, causing the sealing ring 22 to move away from the reserved gap. At this time, the reserved gap opens, and water can flow into the cavity of the mounting cylinder 1 through the reserved gap, thereby achieving the drainage function.

[0062] In this embodiment, two spaced-apart mounting rings 23 are fixedly installed on the outer peripheral wall of the first connecting cylinder 2 near the mounting cylinder 1. The two mounting rings 23 are parallel and coaxial with both the mounting cylinder 1 and the first connecting cylinder 2, and the outer diameter of the mounting rings 23 is the same as the inner diameter of the mounting cylinder 1. A sealing ring 22 is installed between the two mounting rings 23. When the bouncing core 10 is in a non-bouncing state, the mounting rings 23 are inserted into the top part of the mounting cylinder 1. At this time, the sealing ring 22 located between the two mounting rings 23 seals the pre-reserved gap between the mounting cylinder 1 and the first connecting cylinder 2. The sealing ring 22 installed between the two mounting rings 23 serves to limit and fix the sealing ring 22. During the operation of the bouncing core 10, especially when it is not bouncing, the mounting rings 23 extend into the top part of the mounting cylinder 1, which can prevent the sealing ring 22 from shifting or deforming excessively, always maintaining a good sealing state, effectively extending the service life of the sealing ring 22, and improving the overall sealing performance.

[0063] Furthermore, in some specific embodiments, the pressing cylinder 4 is not only fixedly connected to one end of the second connecting cylinder 3, but the outer diameter of the pressing cylinder 4 is equal to the outer diameter of the first connecting cylinder 2, which improves the aesthetics.

[0064] More specifically, a ceramic disc 40 is fixedly installed at the end of the push-button cylinder 4 away from the second connecting cylinder 3. The ceramic disc 40 has a smooth and delicate surface and a rich variety of colors and textures, which can add a unique visual effect to the push-button cylinder 4, making the drain assembly more aesthetically pleasing and textured. This allows it to better blend with different styles of bathroom or kitchen decoration environments, enhancing the overall decorative quality of the space. At the same time, the surface texture of the ceramic disc 40 is warm and smooth, comfortable to the touch, and does not produce a cold or rough discomfort when in contact with the skin, providing a better tactile experience for the user during operation.

[0065] More specifically, at least one overflow hole 41 can be formed on the peripheral wall of the push-button cylinder 4 at the end away from the second connecting cylinder 3. When the pop-up drain seals the ceramic basin, the overflow hole 41 can effectively prevent excessive water in the basin from overflowing. In this embodiment, in order to achieve a better overflow effect, two overflow holes 41 are symmetrically formed on the peripheral wall of the push-button cylinder 4.

[0066] More specifically, a guide ring 42 is coaxially sleeved on the peripheral wall of the end of the actuating cylinder 4 away from the second connecting cylinder 3. The guide ring 42 is fixedly connected to the actuating cylinder 4 by multiple guide brackets 43, and the installation position of the guide ring 42 is below the overflow hole 41. In this embodiment, six guide brackets 43 are provided and evenly distributed along the circumference of the guide ring 42.

[0067] During operation of the push-button cylinder 4, the guide ring 42 is fixedly connected to the push-button cylinder 4 via multiple guide brackets 43, providing precise guidance for the up-and-down movement of the push-button cylinder 4. This ensures that the push-button cylinder 4 maintains a stable movement trajectory even with frequent pressing, preventing shaking, deviation, or jamming, thus guaranteeing the stability and reliability of the drain's push-button function and making user operation smoother. Simultaneously, the guide ring 42 is installed below the overflow hole 41, effectively preventing water flow and debris from directly impacting the overflow hole 41. During drainage, the water flow may carry some impurities; the guide ring 42 prevents these impurities from clogging the overflow hole 41, ensuring the normal drainage function of the overflow hole 41, extending its service life, and ensuring its continued effectiveness in preventing overflow from the ceramic basin.

[0068] Furthermore, in some specific embodiments, a fixing sleeve 20 is fixedly installed inside the first connecting cylinder 2. One end of the fixing sleeve 20 is connected to the spring end of the spring core 10, and the other end of the fixing sleeve 20 is connected to the end of the first connecting cylinder 2 away from the mounting cylinder 1 via an adjusting component 5, so as to adjust the installation height of the second connecting cylinder 3 on the first connecting cylinder 2. The adjusting component 5 allows the installation height of the second connecting cylinder 3 on the first connecting cylinder 2 to be flexibly adjusted to adapt to water tanks or containers of different depths.

[0069] Specifically, such as Figure 2 , 4 As shown in Figures 6, 7, and 8, the adjusting assembly 5 includes a receiving cylinder 52, a spring 53, and a push rod 55.

[0070] The receiving cylinder 52 is a cylindrical structure with the same outer diameter as the fixed sleeve 20. It is disposed on the other end face of the fixed sleeve 20, and the bottom end of the receiving cylinder 52 is fixedly connected to the other end of the fixed sleeve 20. The spring 53 is installed inside the receiving cylinder 52, and one end of the spring 53 is connected to the bottom end of the receiving cylinder 52.

[0071] The bottom end of the push rod 55 extends into the receiving cylinder 52 and is connected to the other end of the spring 53. The push rod 55 is fixedly installed inside the second connecting cylinder 3, and the push rod 55 and the second connecting cylinder 3 are coaxially arranged. In this embodiment, the push rod 55 is connected to the second connecting cylinder 3 through three circumferentially evenly distributed push rod supports 551.

[0072] The outer diameter of the second connecting cylinder 3 is smaller than the inner diameter of the first connecting cylinder 2, allowing for nested installation. Two sliders 50 are symmetrically arranged on the outer periphery of the second connecting cylinder 3. Two semi-circular sliding plates 51 are symmetrically fixed to the inner periphery of the first connecting cylinder 2. Multiple spaced grooves 510 are parallel to each other along the arc direction on the sliding plates 51. Each groove 510 has a fixing groove 511 at its bottom for accommodating the slider 50. The fixing groove 511 communicates with the groove 510 to form an L-shaped sliding track. The slider 50 is slidably installed within the L-shaped sliding track. When the slider 50 slides into the fixing groove 511, the second connecting cylinder 3 is fixedly installed on the first connecting cylinder 2. In this embodiment, the sliding plate 51 is semi-circular, with the same arc as the first connecting cylinder 2. Four grooves 510 are provided, parallel and spaced apart, with the length of each groove 510 being less than the length of the sliding plate 51.

[0073] The adjustment process of the adjustment component 5 is roughly as follows: When it is necessary to adjust the position of the second connecting cylinder 3 on the first connecting cylinder 2, a rotational force is applied to the second connecting cylinder 3. Since the push rod 55 is fixed inside the second connecting cylinder 3, and the bottom end of the push rod 55 is connected to the spring 53 inside the receiving cylinder 52, the external force pushes the second connecting cylinder 3, causing the push rod 55 to compress or stretch the spring 53. At the same time, the slider 50 on the outer peripheral wall of the second connecting cylinder 3 slides in the L-shaped sliding track (formed by the connection of the sliding groove 510 and the fixed groove 511) on the sliding plate 51 on the inner peripheral wall of the first connecting cylinder 2.

[0074] Once the slider 50 has slid along the groove 510 to the appropriate position, the second connecting cylinder 3 is pushed further, causing the slider 50 to slide into the fixing groove 511. At this time, the elastic force of the spring 53 acts on the push rod 55, and then on the second connecting cylinder 3, so that the slider 50 is stably held in the fixing groove 511, realizing the fixed installation of the second connecting cylinder 3 on the first connecting cylinder 2, and completing the height adjustment and positioning.

[0075] To readjust the position of the second connecting cylinder 3, reverse the operation, overcome the elastic force of the spring 53 to make the slider 50 slide out of the fixed groove 511, slide it again in the groove 510 to the new position, and then slide it into the corresponding fixed groove 511 for fixing.

[0076] The fixed groove 511 in the L-shaped sliding track provides a stable positioning point for the slider 50. When the slider 50 slides into the fixed groove 511, the second connecting cylinder 3 is firmly fixed to the first connecting cylinder 2 with the assistance of the spring 53, preventing loosening or displacement during use and ensuring the stability of the overall structure of the drain assembly. At the same time, the spring 53 acts as a buffer during adjustment, reducing the impact force during adjustment, avoiding rigid collisions between components, extending the service life of each component of the drain assembly, and making the adjustment process smoother and more comfortable.

[0077] More specifically, the end of the receiving cylinder 52 facing away from the fixed sleeve 20 is open. A top plate 54 is installed inside the receiving cylinder 52, located at the top of the spring 53, that is, near the opening of the receiving cylinder 52. The outer diameter of the top plate 54 is equal to the inner diameter of the receiving cylinder 52, and the upper surface of the top plate 54 is connected to the bottom end of the push rod 55 to form a stable structure.

[0078] When the push rod 55 is subjected to force, it presses downward against the top plate 54, which in turn compresses the spring 53. Because the spring 53 is elastic, after the external force is removed, it generates an upward elastic force, pushing the top plate 54 and push rod 55 back to their original positions. This allows the push rod 55 to move up and down within a certain range, thereby driving the second connecting cylinder 3 to move up and down. The outer diameter of the top plate 54 is equal to the inner diameter of the receiving cylinder 52, ensuring a tight fit and stable force transmission during the movement of the push rod 55. This prevents swaying or deviation and guarantees the stability of the entire device. Simultaneously, the spring 53 acts as a buffer; when subjected to external impact, it absorbs some energy, reducing the impact on other components and extending the device's service life.

[0079] Meanwhile, an annular snap-fit ​​edge 520 can be formed along the circumference of the inner wall surface of the opening end of the receiving cylinder 52. The snap-fit ​​edge 520 is used to prevent the top plate 54 from being ejected into the mounting cylinder 52 by the spring 53.

[0080] Furthermore, in some specific embodiments, the side wall of the receiving cylinder 52 is provided with at least one rectangular drainage hole 521, which is used to drain water accumulated inside the receiving cylinder 52 and extend its service life. In this embodiment, two drainage holes 521 are vertically arranged and symmetrically positioned.

[0081] Furthermore, in some more specific embodiments, such as Figure 2 , 5 As shown in Figures 6 and 9, the cleaning component 6 is used to clean the groove wall and bottom wall of the ceramic basin that accommodates the drainer, and it includes:

[0082] Rotating ring 60, the rotating ring 60 is sleeved and installed on the outer peripheral wall of the first connecting cylinder 2 near the mounting cylinder 1, and is rotatably connected to the outer peripheral wall of the first connecting cylinder 2;

[0083] A cleaning blade 61 is fixedly connected to the rotating ring 60. The cleaning blade 61 is composed of three surfaces: a straight surface 610, an arc surface 611, and a curved surface 612.

[0084] A brush 62 is disposed on the lower surface of the cleaning blade 61 and is used to clean the bottom wall of the groove in the ceramic basin that accommodates the drainer.

[0085] Scraper 63 is fixedly installed on the upper surface of the cleaning blade 61 and located at the arc surface 611. The arc of the scraper 63 is the same as the arc of the arc surface 611.

[0086] A rotating blade 64 is fixedly mounted on the upper surface of the cleaning blade 61 and located at the curved surface 612. The curvature of the rotating blade 64 is the same as that of the curved surface 612. In this embodiment, the angle between the rotating blade 64 and the cleaning blade 61 is an obtuse angle. When water flows and impacts the rotating blade 64, the obtuse angle design makes the contact area and angle between the water flow and the rotating blade more conducive to converting the kinetic energy of the water flow into the rotational power of the rotating blade 64. Compared with right angles or acute angles, obtuse angles allow the water flow to act more fully on the rotating blade 64, making it easier for the rotating blade 64 to start rotating under the action of the water flow and to obtain a greater rotational speed, thereby more effectively driving the cleaning blade 61 to rotate and improving the rotational efficiency of the entire cleaning assembly.

[0087] During operation, when water flows through the drain, it impacts the rotating blade 64 fixed to the curved surface 612 on the upper surface of the cleaning blade 61. Because its curvature matches that of the curved surface 612, it drives the cleaning blade 61 to rotate. The cleaning blade 61 is connected to a rotating ring 60 that is fitted onto the outer peripheral wall of the first connecting cylinder 2 and can rotate relative to it, causing the entire cleaning assembly to rotate around the first connecting cylinder 2. During rotation, the brush 62 on the lower surface of the cleaning blade 61 scrubs the bottom wall of the groove. The side surface surrounded by the straight surface 610, the arc surface 611, and the curved surface 612 contacts the groove wall. With the help of the scraper 63, which is installed at the arc surface 611 and has the same curvature, it can better fit the groove wall and scrape off the dirt attached to the groove wall.

[0088] The brush 62 and scraper 63 work simultaneously, cleaning the bottom and sides of the groove respectively, greatly improving cleaning efficiency and effectively removing various dirt and impurities from the ceramic basin's groove. Meanwhile, the rotating blades 64, driven by the force of water flow, achieve a degree of automatic cleaning, eliminating the need for manual operation and providing a more convenient and labor-saving user experience. Furthermore, the curvature of the scraper 63 matches the arc surface 611 of the cleaning blades 61, allowing the cleaning components to better conform to the shape of the ceramic basin's groove during operation, ensuring thorough cleaning without blind spots and guaranteeing effective cleaning results.

[0089] Specifically, a receiving groove 24 is formed on the outer peripheral wall of the first connecting cylinder 2 near the mounting cylinder 1. Correspondingly, the rotating ring 60 is installed in the receiving groove 24 and can rotate within it. The receiving groove 24 provides an axial mounting position for the rotating ring 60, restricting its axial movement. This ensures that during operation, the cleaning components such as the cleaning blades 61, brushes 62, scrapers 63, and rotating blades 64 can stably clean the walls and bottom of the ceramic basin groove, preventing the cleaning position from shifting due to axial movement of the rotating ring 60 and affecting the cleaning effect. Simultaneously, the presence of the receiving groove 24 provides a certain degree of constraint on the rotating ring 60, reducing the risk of it detaching from the first connecting cylinder 2.

[0090] In this embodiment, the rotating ring 60 is divided into a first ring portion 601 and a second ring portion 602. Both ends of the first ring portion 601 are provided with mounting holes, and both ends of the second ring portion 602 are provided with mounting protrusions that match the mounting holes. The mounting protrusions are installed into the mounting holes to achieve a fixed connection between the first ring portion 601 and the second ring portion 602.

[0091] In this embodiment, five cleaning blades 61 are evenly arranged along the circumferential direction of the first connecting cylinder 2. The height of the rotating blades 64 gradually increases, with the highest point near the scraper 63. When water flows through the drain and impacts the rotating blades 64, the gradually increasing height design allows the rotating blades 64 to have greater contact with the water flow. The higher point near the scraper 63 means that more water flow energy can be intercepted at this position. The water flow generates a greater impact force on the higher part of the rotating blades 64, which is then converted into a stronger rotational torque. This makes the rotating blades 64 drive the cleaning blades 61 to rotate more smoothly and efficiently, improving the rotational speed and power of the entire cleaning assembly and better utilizing the energy of the water flow to achieve the cleaning function.

[0092] Furthermore, in some specific embodiments, a sponge sheet is provided on the outer wall surface of the scraper 63 on the side away from the rotating ring 60. The sponge sheet is used to clean the wall of the ceramic basin that accommodates the drain recess. The sponge has good water absorption and adsorption properties, which can effectively absorb water stains, oil stains, and other dirt on the wall of the ceramic basin recess and remove them from the surface of the wall. Compared with the scraper 63 alone, it can better remove some sticky stains and improve the thoroughness of cleaning. At the same time, the sponge sheet has a certain degree of elasticity and softness, which can act as a buffer between the scraper 63 and the wall of the ceramic basin, avoiding excessive scraping that may occur when the scraper 63 directly contacts the wall, thereby preventing scratches or damage to the wall of the ceramic basin and protecting the surface integrity and aesthetics of the ceramic basin.

[0093] At the same time, at least one water passage hole 630 can be provided on the scraper 63, for example, two elongated holes can be provided. The main function of these water passage holes 630 is to allow the water in the ceramic basin to flow smoothly into the groove that accommodates the drain.

[0094] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
