Description

Technical Field

[0001] This utility model relates to the field of floor drain device technology, and in particular to a floor drain core. Background Technology

[0002] Floor drains are key components connecting indoor floor drainage to sewer pipes. Their core functions are to ensure smooth drainage, intercept debris, prevent blockages, and block odors and pests from entering the room. Traditional floor drains and existing improved floor drains have revealed many insurmountable problems in long-term use, mainly in the following aspects: inconvenient filtration and cleaning, and poor user experience: most floor drains rely on fixed filters or basket-type filters to intercept hair, fibers, and other debris.

[0003] When debris accumulates and clogs the filter holes, users must disassemble the filter components (e.g., by hand or with tools to remove the filter screen or lift the filter basket). The disassembly process can be troublesome (especially for deeply recessed or complex floor drains), and precise repositioning is required after cleaning; otherwise, the sealing or drainage performance will be affected, seriously impacting the user experience and the long-term reliability of the floor drain.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-5 The drain core shown includes a drain body 1, a filter element 2, and a shaping element 3 disposed in a drain installation groove. The drain body 1 has a drainage channel 4, and the shaping element 3 is located above the drain body 1. The filter element 2 includes a flexible filter cylinder 5 and a handle 6. The flexible filter cylinder 5 can be deformed relative to the shaping element 3 to be pulled into or out of the drainage channel 4. When the flexible filter cylinder 5 is inside the drainage channel 4, the opening faces upward, and when the flexible filter cylinder 5 is outside the drainage channel 4, the opening faces downward. The flexible filter cylinder 5 has filter holes 7 on its peripheral wall, and the flexible filter cylinder 5 is made of an elastic material. The handle 6 is provided on the flexible filter cylinder 5 for pulling the flexible filter cylinder 5. The flexible filter cylinder 5 and the shaping element 3 are integrally formed or fixedly connected. In this embodiment, the filter element 2 as a whole or the flexible filter cylinder 5 is made of materials such as rubber, silicone, or thermoplastic elastomer, which can ensure that it can be shaped after being pulled in or out.

[0023] The flexible filter cartridge 5 can switch between two states: pull-in and pull-out. When the flexible filter cartridge 5 is pulled out, simply pull it upwards using the handle 6. Its body deforms relative to the rigid shaping ring 10 and is pulled out of the drainage channel 4, at which point the opening naturally faces downwards. The intercepted waste can be easily removed, and the dirt can be manually scraped off the surface, achieving quick cleaning without disassembly.

[0024] The flexible filter cylinder 5 extends radially outward from its outer edge to form a flange 8, and an annular groove 9 is provided on the end face of the flange 8; the shaping component 3 includes a rigid shaping ring 10, which is embedded in the annular groove 9; the rigid shaping ring 10 has a central hole 11 coaxially arranged with the flexible filter cylinder 5, and the flexible filter cylinder 5 can be axially displaced relative to the central hole 11 to achieve the switching between the two states of the cylinder body being pulled in and pulled out. The flexible filter cylinder 5 and the rigid shaping ring 10 are integrated or fixedly connected through the nested structure of the annular groove 9, which ensures the morphological stability of the flexible filter cylinder 5 during the deformation and pulling process, and provides precise guidance (central hole 11) for the movement (axial displacement) of the flexible filter cylinder 5, preventing deflection and jamming. In this embodiment, normal traction will not pull the filter component 2 out completely, but only the central flexible filter cylinder 5 will be pulled.

[0025] The annular groove 9 is provided with several supporting protrusions 12 along its circumference. A rigid shaping ring 10 is placed on the upper end of the supporting protrusions 12. The lower end face of the rigid shaping ring 10 and the upper end face of the annular groove 9 form a drainage gap 13. The upper end face of the rigid shaping ring 10 is provided with several drainage holes 14 along its circumference. The drainage gap 13 formed by the lower end face of the rigid shaping ring 10 and the upper end face of the annular groove 9, and the circumferential drainage holes 14 on its upper end face, constitute an additional drainage channel 4. In addition to directly entering the drainage channel 4, water can also enter the drainage channel 4 through the drainage gap 13, greatly improving the drainage reliability of the floor drain. The supporting protrusions 12 further ensure the existence and stability of the drainage gap 13.

[0026] The handle 6 is located at the center of the flexible filter cylinder 5. Several filter holes 7 are provided and arranged around the handle 6 on the inner wall of the flexible filter cylinder 5. The size of the filter holes 7 is set according to the actual situation to prevent large particles of impurities from entering the pipe and causing pipe blockage.

[0027] The handle 6 has a columnar structure and extends to the outer end of the opening of the flexible filter cartridge 5. It can be lower than the opening or flush with it. Of course, in this application, it is preferred to extend beyond the opening.

[0028] The upper end of the drain body 1 is provided with a positioning retaining ring 15, and the lower end face of the flange 8 is provided with an annular connecting part 18 coaxially arranged with the central hole 11. The annular connecting part 18 is provided with an annular groove 19 for the positioning retaining ring 15 to be embedded, which can quickly assemble the filter element 2 and the drain body 1. In this embodiment, the diameter of the annular connecting part 18 is larger than the diameter of the central hole 11. The flexible sealing sleeve 16 is fitted over the drain body 1, which can tightly fit the inner wall of the drain installation groove of different sizes and shapes, effectively preventing water from leaking from the gap between the drain core and the installation groove, and ensuring that all water flows through the filtration system.

[0029] The drain body 1 has a hinged cover 17 at its lower opening, which is based on a torsion spring structure. This is existing technology and will not be described in detail in this application. When there is no water flow or the water flow is small, the cover 17 automatically closes under the action of the torsion spring, tightly sealing the drain pipe opening and completely preventing odors, mosquitoes, and cockroaches from flowing back into the room. When draining, the force of the water flow can easily push open the cover 17, ensuring smooth drainage. This design saves more space and is less prone to drying out and failure than traditional water-sealed odor prevention.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples of this utility model and are not intended to limit it. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
