Description

Technical Field

[0001] This utility model relates to the technical field of wastewater sanitary pipeline devices, and in particular to odor-proof sealing. Background Technology

[0002] With the continuous development of modern life and people's increasing demand for a comfortable quality of life, the functions of modern bathrooms have been expanded in depth. Sunken bathrooms, with their larger space and beautiful appearance, are becoming increasingly popular. However, the drainage system of sunken bathrooms is buried under the ground, making cleaning very inconvenient. A reasonable pipe system needs to be installed before the floor tiles and cement are laid. The drainage and odor prevention of the bathroom rely on in-floor drains with water seals. In-floor drains are pipe components that are pre-installed in the bathroom floor, and their purpose is to block odors during bathroom use. For example, Chinese patent CN202672324U discloses a novel odor-proof floor drain, providing the following technical solution: This utility model discloses a novel odor-proof floor drain, relating to a water supply and drainage product installed in a fixed building for sewage discharge. The odor-proof floor drain includes a mounting base, a drain hole, an odor-proof component, and a leakage component. Its disclosed technical feature is a split-type mounting base, mainly composed of a base and a removable, sealed insert connected to the top of the base. The upper body can be appropriately heightened at the factory, so that if the mounting base is installed too high on the ground during actual construction, the height of the upper body can be adjusted simply by cutting, thus greatly facilitating construction. However, the aforementioned novel odor-proof floor drain cannot be quickly disassembled to clean hair and other debris, leading to easy clogging during actual use and thus failing to achieve its odor-proof function. Utility Model Content

[0003] This invention solves the problems of difficulty in quick disassembly, inconvenience in cleaning, and easy clogging in the prior art, and proposes a floor drain that can be quickly disassembled, achieving the goals of being aesthetically pleasing, easy to disassemble, convenient to maintain, odor-proof, and not prone to clogging.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quick-detachable floor drain includes a floor drain body and a floor drain metal panel. A filter screen is installed below the floor drain metal panel. A floor drain end cap is connected to the top of the floor drain body to form a whole. The filter screen has a round hole in the middle and a notch on the side of the round hole. The floor drain metal panel has a protrusion.

[0006] The advantage of this design is that it achieves functional partitioning through a four-layer structure of main body / end cap / filter / panel. The round holes and notches form an axial limiting channel, and the protrusions form a rotating buckle structure, providing a mechanical basis for subsequent quick disassembly. At the same time, the double-layer interception of the filter and metal mesh improves the hair capture efficiency.

[0007] Preferably, the notch is the same size and shape as the protrusion.

[0008] The advantage of this design is that it ensures that the protrusion can accurately fit into the notch to form a positioning when rotated into place, avoiding assembly interference caused by dimensional deviations. At the same time, when rotated in the opposite direction, the protrusion and the notch are misaligned to generate a lifting force, and the reliable switching between self-locking and release is achieved by using geometric matching relationship.

[0009] Preferably, the metal panel of the drain is connected to the drain body by a thread, and the top of the drain end cap is provided with a mounting groove that is adapted to the drain panel.

[0010] The advantages of this design are that the threaded connection provides a stable axial preload to prevent the panel from loosening, the mounting groove forms a radial constraint to limit horizontal displacement, and the dual fixing mechanism ensures sealing while enabling one-handed rotation operation, which is in line with ergonomic design.

[0011] Preferably, the drain body and the drain end cap are welded together as a whole, the drain end cap is provided with a through hole, and the edge of the through hole is provided with a recessed structure that is adapted to the filter screen.

[0012] The advantages of this design are that the welding process eliminates joint gaps and improves the waterproof rating, the recessed through holes form a flow guide slope to accelerate drainage, and at the same time provide a stepped support surface for the filter screen to prevent the filter screen from shifting under the impact of fluid.

[0013] Preferably, the shaft of the drain metal panel passes through the circular hole and is connected to the drain body.

[0014] The advantage of this design is that it uses a central shaft through-type design to achieve linkage control of rotational motion and axial lifting. The guiding effect of the shaft ensures the accuracy of the panel rotation trajectory, while the shaft itself can also serve as a drainage channel to enhance fluid flow.

[0015] Preferably, the protrusion is located on the bottom side of the axis of the drain metal panel.

[0016] The advantage of this design is that placing the protrusions in the stress concentration area of ​​the shaft can improve the structural strength, and setting the bottom side to shorten the lever arm reduces the rotational torque. Combined with the notch, it forms an eccentric lifting mechanism, so that the filter screen generates axial displacement as the panel rotates.

[0017] Preferably, the filter screen adopts a comb-shaped design, and the metal panel of the floor drain is vortex-shaped.

[0018] The advantage of this design is that the comb-shaped grid forms a multi-level hair interception layer and facilitates reverse combing and cleaning, the vortex panel texture generates a centripetal flow guiding effect to accelerate drainage, and the spiral texture enhances surface friction to facilitate twisting operation.

[0019] Preferably, the drain body is provided with connecting pipes on both sides.

[0020] The advantage of this design is that the dual-channel structure achieves redundant drainage paths, can adapt to the needs of branch pipe access in different directions, and the symmetrical arrangement on both sides balances the fluid pressure, reducing the turbulence noise generated when draining from one side.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0022] 1. This utility model achieves functional zoning through a four-layer structure consisting of a main body, end caps, a filter, and a panel, providing highly efficient hair capture capabilities. The dual interception design of the filter and metal mesh significantly improves hair capture efficiency and reduces drainage problems caused by hair blockage. Simultaneously, the axial limiting channel formed by the round holes and notches, combined with the rotating snap-fit ​​structure formed by the protrusions, makes disassembly simple and quick, allowing users to easily clean and maintain the drain, avoiding the complex and time-consuming disassembly issues of traditional floor drains.

[0023] 2. The threaded connection and mounting groove of this utility model ensure the stability and sealing of the drain's metal panel, preventing panel loosening and leakage. By providing stable axial preload and radial restraint, the dual fixing mechanism makes the drain more reliable during use. At the same time, this design is ergonomic, allowing users to easily operate it with one hand, improving convenience and comfort.

[0024] 3. The welded structure and through-hole design of this utility model improve its waterproof rating and fluid flow. The welding process eliminates joint gaps, forming a sunken through-hole to accelerate drainage and ensure that the filter screen is not easily displaced. The central shaft ensures the linkage control of the panel's rotational movement and axial lifting, enhancing the overall structural strength of the drain, reducing torque during operation, making the use process smoother, and improving user experience and satisfaction.

[0031] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. The proportions of the components are not drawn to scale, and the proportions and dimensions shown in the drawings should not limit the essential technical solutions of this utility model. These embodiments do not exhaustively describe all details, nor do they limit this utility model to merely the specific embodiments described.

[0032] See Figures 1 to 4 As shown, a quick-detachable floor drain includes a floor drain body and a floor drain metal mesh. A filter screen is installed below the floor drain metal mesh. The floor drain body is connected to a floor drain end cap to form a whole. The filter screen has a round hole in the middle and a notch on the side of the round hole. The floor drain metal panel has a protrusion.

[0033] This utility model achieves functional partitioning through a four-layer structure: main body / end cap / filter / panel. The round hole and notch form an axial limiting channel, which, together with the protrusion, forms a rotating buckle structure, providing a mechanical basis for subsequent quick disassembly. At the same time, the double-layer interception of the filter and metal mesh improves the hair capture efficiency.

[0034] like Figure 1 In one embodiment shown, Figure 1This is a structural schematic diagram of one embodiment of a quick-detachable floor drain according to the present invention. The present invention relates to a quick-detachable floor drain, comprising a floor drain body 1 and a floor drain metal panel 4. A high-efficiency filter screen 3 is installed at the bottom of the floor drain metal panel 4 to ensure the interception of impurities during fluid flow. The upper part of the floor drain body 1 is welded to the floor drain end cap 2 to form a complete structure, enhancing overall stability and sealing. Furthermore, the top of the floor drain end cap 2 is designed with an installation groove adapted to the floor drain panel 4, further improving the structural integrity and ease of operation of the device. The welded connection between the floor drain body 1 and the floor drain end cap 2 effectively eliminates potential connection gaps, thereby improving waterproof performance. The floor drain end cap 2 is also designed with a through hole, the edge of which adopts a recessed structure to adapt to the filter screen 3, so as to better stabilize the position of the filter screen and prevent it from shifting under the impact of water flow.

[0035] The filter screen 3 features a comb-shaped structure, effectively creating multi-stage interception layers to improve the capture efficiency of hair and other debris. Meanwhile, the drain metal panel 4 has a vortex shape, which not only enhances aesthetics but also creates a centripetal flow effect, increasing drainage speed. To accommodate different drainage needs, the drain body 1 has connecting pipes on both sides, forming a dual-channel structure for redundant drainage paths. This dual-channel design ensures balanced fluid pressure distribution during single-sided drainage, reducing noise caused by turbulence and improving the user experience.

[0036] The advantages of this invention lie in its functional partitioning of the four-layer structure (body / end cap / filter / panel), ensuring the effective operation of different functional modules. The combination of the filter 3 and the drain metal panel 4 achieves efficient double-layer interception, significantly improving the capture rate of hair and other debris. Furthermore, the welded connection eliminates seams, significantly enhancing the waterproof rating and overall strength, ensuring safe use under high water pressure. The recessed through-hole design creates a guiding slope for fluid as it passes through the filter 3, further accelerating drainage efficiency. The threaded connection between the drain metal panel 4 and the drain body 1 provides stable pre-tightening force, preventing the panel from loosening due to vibration or use. Simultaneously, the mounting groove allows for rotation, conforming to ergonomic design principles. Users can easily perform one-handed rotation, greatly reducing inconvenience during use.

[0037] like Figure 2 In one embodiment shown, Figure 2This is a top view of the filter screen of an embodiment of the quick-detachable floor drain according to this utility model. The filter screen 3 of this utility model has a central circular hole 3.1 and notches 3.2 on its sides to facilitate smooth fluid flow. The metal panel 4 of the floor drain passes through the circular hole 3.1 and is connected to the floor drain body 1. The filter screen 3 adopts a comb-shaped structure design, which enables it to efficiently intercept debris and improve its performance.

[0038] The combination of the round holes 3.1 and notches 3.2 in the filter screen 3 provides axial restraint, ensuring that the drain metal panel 4 can be stably and accurately positioned during rotation, facilitating subsequent operation and maintenance. The comb-shaped design of the filter screen 3 effectively increases the interception layers, improving the capture efficiency of hair and other debris, and enhancing overall drainage performance. These features work together to make this drain excellent in both functionality and ease of use, meeting the needs of both residential and commercial spaces for efficient and reliable drainage systems.

[0039] like Figure 3 In one embodiment shown, Figure 3 This is a schematic diagram of the filter screen and metal panel structure of an embodiment of a quick-detachable floor drain according to this utility model. The quick-detachable floor drain designed in this utility model mainly consists of a floor drain body 1, a floor drain metal panel 4, and a floor drain end cap 2. A high-efficiency filter screen 3 is installed below the floor drain metal panel 4 to intercept debris. The floor drain body 1 is welded to the floor drain end cap 2 to form a whole, enhancing the stability and sealing of the structure. The floor drain metal panel 4 has a protrusion 4.3, which serves a positioning and locking function in the design. The metal panel 4 is connected to the body 1 by an internal thread 4.2, ensuring the stability of the floor drain during use. Furthermore, the top of the floor drain end cap 2 has a mounting groove that matches the metal panel 4, facilitating installation and disassembly.

[0040] The shaft of the metal panel 4 of the floor drain passes through the circular hole 3.1 and connects to the floor drain body 1, thereby realizing the linkage control of rotation and lifting. This design not only provides a convenient operation method, but also ensures the precise fit between the components, making the equipment more reliable in actual use. Through the above design, the functions of each part of the floor drain are effectively divided, and they can be quickly disassembled when needed, facilitating cleaning and maintenance.

[0041] This design offers numerous advantages. First, the overall structure of the drain is meticulously designed for quick disassembly and easy cleaning. The filter screen 3 effectively prevents debris from entering the drain pipe, ensuring unobstructed drainage, while its comb-shaped design adds layers of interception, significantly improving the filtration effect. Second, the internal thread 4.2 connection between the protrusions 4.3 on the drain's metal panel 4 and the main body 1 not only enhances the fixing performance but also facilitates quick disassembly and installation by the user when needed, reducing maintenance time.

[0042] Furthermore, the mounting groove design on the top of the drain end cap 2 ensures a tighter fit between the metal panel 4 and the main body 1, preventing leaks or poor drainage caused by loosening. This design significantly improves the lifespan and stability of the drain, adapting to the needs of various environments, including residential, commercial, and industrial settings.

[0043] In practical applications, the efficiency and convenience of this type of floor drain make it an ideal choice, especially in places that require frequent cleaning, such as bathrooms and kitchens. Users can easily remove the metal panel 4 for cleaning, avoiding the problem of dirt accumulation caused by water flow, thus effectively reducing the possibility of odors and bacterial growth.

[0044] like Figure 4 In one embodiment shown, Figure 4 This is a partially enlarged view of the shaft of the metal panel of a floor drain according to an embodiment of the present invention, which is a quick-detachable floor drain.

[0045] The metal panel 4 of the floor drain has a protrusion 4.3, the cross-sectional size and shape of which are consistent with the notch 3.2, allowing them to fit together. The metal panel 4 of the floor drain is connected to the floor drain body 1 by an internal thread 4.2, ensuring the stability and sealing of the structure. At the same time, the protrusion 4.3 is located on the bottom side of the shaft of the metal panel 4, further enhancing the overall fixing effect.

[0046] First, the matching shape of the protrusion 4.3 and the notch 3.2 ensures good positioning and locking functions, helping to maintain the stability of the metal panel 4 during use and reducing loosening caused by vibration or water flow. The internal thread 4.2 connection allows users to easily and quickly install and remove the metal panel 4, facilitating subsequent cleaning and maintenance and greatly improving ease of use. Furthermore, this structural design effectively prevents sewage leakage and debris blockage, improving the efficiency of the drainage system and ensuring good drainage performance in daily use. Therefore, this design not only enhances the functionality of the floor drain but also extends its service life, meeting users' needs for efficient and reliable drainage equipment.

[0047] In another embodiment, this utility model consists of four parts: a drain body 1, a drain end cap 2, a comb-shaped filter screen 3, and a drain metal panel 4. The drain body 1 and the drain end cap 2 are connected as a whole by welding or other means to form a drain body with a sealed space. The drain metal panel 4 is connected to the drain body 1 by threads to prevent horizontal movement of the metal panel. The comb-shaped filter screen 3 has a small circular hole in the middle, allowing the shaft of the drain metal panel 4 to pass through. The small notch of the comb-shaped filter screen 3 is the same size as the small protrusion of the drain metal panel 4. During installation, the small notch and small protrusion are aligned. During disassembly and cleaning, the drain metal panel can be quickly disassembled by rotating it. Since the small notch and small protrusion are unlikely to overlap after rotation, the comb-shaped filter screen 3 can be taken out together, and hair and other blockages can be cleaned by the comb teeth, which is convenient and quick. Under the premise of ensuring smooth drainage, this invention solves the problem of hair blockage and achieves the purpose of easy disassembly and cleaning during use.

[0048] In summary, this utility model proposes a quick-disassembly floor drain with a unique structural design. It consists of four parts: the drain body, a metal mesh, a filter, and end caps, forming an efficient and reliable drainage system. The filter, located below the metal mesh, has a central hole with notches on its sides, and the metal panel features raised sections. This design allows for functional zoning, enabling different components to perform their respective functions and improving overall efficiency.

[0049] First, the drain's four-layer structure (body, end caps, filter, and metal panel) greatly enhances its ability to capture hair and other debris. The dual interception design of the filter and metal mesh effectively reduces drainage problems caused by hair blockage, while avoiding the tedious and time-consuming cleaning of traditional drains. The axial limiting channel formed by the round holes and notches, combined with the rotating snap-fit ​​structure formed by the protrusions, allows users to easily and quickly disassemble each part during cleaning and maintenance, greatly improving ease of use.

[0050] Secondly, the metal panel of the drain is connected to the main body via threads, and the top of the drain end cap has a mounting groove that fits the metal panel. This design not only provides stable axial preload to prevent loosening and leakage during use, but also restricts horizontal displacement through radial constraints, forming a double fixing mechanism to ensure the reliability and safety of the drain in daily use. Furthermore, this design is ergonomic, allowing users to easily operate it with one hand, improving convenience and comfort.

[0051] The welded structure and through-hole design of the central axis further enhance the waterproof rating and fluid flow of the drain. The welding process eliminates gaps at the joints, creating recessed through-holes that accelerate drainage while providing a stepped support surface for the filter screen, preventing displacement under fluid impact. The central axis design enables synchronized control of rotational movement and axial lifting, ensuring precise panel rotation. This not only strengthens the overall structure of the drain but also reduces operating torque, making operation smoother and providing a better user experience.

[0052] Furthermore, the shaft of the drain metal panel passes through a circular hole and connects to the main body, forming a stable support structure. A protrusion located on the bottom side of the metal panel shaft places it in a stress concentration area, effectively improving structural strength and shortening the lever arm to reduce rotational torque. Combined with the eccentric lifting mechanism formed by the notch, this allows the filter screen to undergo axial displacement when the panel rotates, further enhancing drainage efficiency.

[0053] Finally, connecting pipes are installed on both sides of the drain body, forming a dual-channel structure. This design provides redundant drainage paths, accommodating branch pipe access requirements in different directions. Simultaneously, the symmetrical arrangement on both sides balances fluid pressure and reduces turbulence noise generated during unilateral drainage. This design ensures the drain maintains optimal performance under various usage environments.

[0054] This utility model is not limited to the above-described embodiments. Any changes made to its shape or material composition, as long as the structural design provided by this utility model is adopted, are considered a variation of this utility model and should be regarded as within the protection scope of this utility model.
