Description

Technical Field

[0001] The present application relates to the technical field of floor drains, and particularly to a floor drain core and a floor drain. Background Art

[0002] A floor drain is a drainage appliance connecting the ground and a drainage pipe system, and is an important interface connecting the drainage pipe system and the indoor ground. As an important component of the drainage system in a residence, a floor drain can guide wastewater into the sewer pipe smoothly. In addition to discharging wastewater, the quality of indoor air is directly affected by the quality of the floor drain. Therefore, generally, a floor drain also needs to have functions such as preventing odors, preventing mosquitoes, and preventing backflow, and these functions are mainly achieved through the floor drain core.

[0003] The floor drain core is the core part of the floor drain, which is used to realize the drainage and odor prevention functions of the floor drain. At present, there are two ways to seal harmful gases in commercially available floor drains: water seal and mechanical seal. Among them, there is a silicone floor drain core in the mechanically sealed floor drain core. The sealing principle of the silicone floor drain core is to use two relatively thin silicone sheets or a silicone bag with an open bottom to seal. When draining water, the bottom of the silicone is washed open by water. After the drainage is completed, the bottom of the silicone automatically fits and seals under the action of its own elastic force to achieve the odor prevention effect.

[0004] However, the existing silicone floor drain cores have the problem that they cannot balance drainage efficiency and sealing performance, and cannot effectively ensure the sealing performance of the floor drain core while improving the drainage efficiency. Summary of the Utility Model

The upper end of the elastic hose is butt-jointed and fixed with the installation sleeve ring, and the lower end of the elastic hose gradually contracts and forms an elastically openable and closable sealing lip at the port of the lower end.

[0007] Wherein, in the sealed state, the sealing lip closes to form an arc-shaped seal.

[0008] In a feasible implementation manner, the arc-shaped seal is in an S shape, and the perimeter of the arc-shaped seal is equal to the perimeter of the water inlet at the upper end of the elastic hose.

[0009] In a feasible implementation manner, the lower end of the elastic hose gradually contracts to form a V-shaped connecting pipe, and the V-shaped connecting pipe is connected to the sealing lip.

[0010] In a feasible implementation, the flexible hose further includes a water intake straight pipe, the upper end of the water intake straight pipe is connected to the mounting collar, and the lower end of the water intake straight pipe is connected to the V-shaped connecting pipe.

[0018] Compared with the prior art, the present application has the following beneficial effects:

[0019] A floor drain core and a floor drain provided by the present application, by setting the sealing shape of the sealing lip to an arc shape, compared with a straight sealing lip, can expand the cross-sectional area of the water outlet of the sealing lip and improve the drainage efficiency of the floor drain core.

[0045] A floor drain is a drainage appliance that connects the ground to the drainage pipe system. It is an important interface between the drainage pipe system and the indoor ground. As an important component of the drainage system in a residence, a floor drain can guide wastewater smoothly into the sewer pipe. In addition to discharging wastewater, the performance of a floor drain also directly affects the indoor air quality. Therefore, a floor drain generally also needs to have functions such as preventing odors, preventing mosquitoes, and preventing backflow of water, and these functions are mainly achieved through the floor drain core.

[0046] The floor drain core is the core part of the floor drain, which is used to realize the drainage and odor prevention functions of the floor drain. At present, there are two ways to seal harmful gases in commercially available floor drains: water seal and mechanical seal. Among them, there is a silicone floor drain core in the mechanically sealed floor drain core. The sealing principle of the silicone floor drain core is to use two relatively thin silicone sheets or a silicone bag with an open bottom to seal. When draining water, the bottom of the silicone is washed open by water. After the drainage is completed, the bottom of the silicone automatically fits and seals under the action of its own elastic force to achieve the odor prevention effect.

[0047] However, the existing silicone floor drain cores have the problem of being unable to balance drainage efficiency and sealing performance. Refer to Figures 1 to 2 , because the upper water receiving cavity of the elastic hose 200 of the existing floor drain core made of silicone is tubular, the middle part is "V"-shaped transition connection, and the lower sealing lip 300 is elastically sealed by two silicone sheets fitting together. The sealing mouth of the sealing lip 300 is in a straight line shape. When wastewater drains into the water receiving cavity and then flows down to the sealing lip 300, the water flow flushes open the two sealing films for drainage; when the water is drained, the two sealing films return to their positions and fit together for sealing under the action of the memory elastic force. Refer to Figure 3 , in the silicone floor drain core with a straight-line sealing lip 300, the width of the sealing lip 300 is equal to the width of the water receiving cavity. Suppose that if the silicone floor drain core with a straight-line sealing lip 300 is installed in a circular sewer pipe and the water receiving cavity is circular, then the perimeter of the water outlet of the sealing lip 300 is equal to 2*d (d is the diameter of the water receiving cavity), which is less than the perimeter of the water inlet of the water receiving cavity, πd. Therefore, the cross-sectional area of the water outlet of the sealing lip 300 is at least 36% smaller than the cross-sectional area of the water inlet of the water receiving cavity. In order to obtain a cross-sectional area of the water outlet of the sealing lip 300 that is the same or similar to the cross-sectional area of the water inlet of the water receiving cavity, refer to Figures 4 to 5 , someone designed a semi-circular lip sealing form, which can improve the drainage efficiency of the floor drain core, but because the deformation of the sealing lip 300 is too large, the reset sealing effect of the floor drain core becomes poor. Someone else designed a cross-shaped (refer to Figures 6 to 7 ) or Y-shaped lip sealing form, which also has the problem that the deformation of the sealing lip 300 is too large and there are gaps when the sealing lip 300 is reset, resulting in poor sealing performance of the sealing lip 300.

[0048] In summary, the existing technology has not effectively solved the problem that the silicone floor drain core can still effectively ensure the sealing performance of the floor drain core while improving the drainage efficiency.

[0049] In response to the above technical problems, the present application proposes a floor drain core. By setting the sealing shape of the sealing lip of the floor drain core to an arc shape, the floor drain core can take into account both drainage efficiency and sealing. While efficiently draining water, it also has good anti-odor function.

[0050] The technical solution of the floor drain core provided by the present application is described in detail below through specific embodiments. It should be noted that the following embodiments may exist alone or in combination with each other, and the same or similar contents may not be described repeatedly in different embodiments.

[0051] Figures 8 to 9 This is a schematic diagram of the structure of a floor drain core provided in an embodiment of the present application, see Figures 8 to 9 In some embodiments, the floor drain core includes a mounting collar 100 and an elastic hose 200, the upper end of the elastic hose 200 is fixedly docked with the mounting collar 100, and the lower end of the elastic hose 200 gradually shrinks and forms a sealing lip 300 that can be elastically opened and closed at the port at the lower end;

[0052] In the sealed state, the sealing lip 300 is closed to form an arc-shaped seal.

[0053] In this embodiment, the floor drain core is installed in the floor drain. In the initial state, the sealing lip 300 will close to form an arc seal under the action of its own elastic force. When wastewater flows into the floor drain core from the water inlet at the installation ring 100, the wastewater flows downward to impact the sealing lip 300. The force of the wastewater will open the sealing lip 300, causing the sealing lip 300 to expand and open, so that the wastewater can be discharged smoothly. When the drainage is completed, due to the elastic force of the elastic hose 200 itself, the sealing lip 300 in the open state will rebound and return to the sealed state. The rebound sealing characteristics of the sealing lip 300 are used to prevent the odor from flowing back into the sewer pipe 600.

[0054] contrast Figure 3 and Figure 10 , the sealing shape of the sealing lip 300 is set to an arc shape. Compared with the straight-shaped sealing lip 300, the water outlet cross-sectional area of the sealing lip 300 can be enlarged, thereby improving the drainage efficiency of the floor drain core. At the same time, compared with the cross-shaped or Y-shaped sealing shape, the arc-shaped sealing lip 300 has the advantages of small deformation and better sealing effect. Therefore, the use of the arc-shaped sealing lip 300 can take into account both drainage efficiency and sealing performance, so that the floor drain core has a good deodorizing function while efficiently draining water.

[0055] See also Figure 9 Preferably, the arc seal is S-shaped, and the circumference of the arc seal is equal to the circumference of the water inlet at the upper end of the elastic hose 200.

[0056] Among them, when the arc seal is S-shaped, and the circumference of the arc seal is consistent with the circumference of the water inlet at the upper end of the elastic hose 200, the cross-sectional area of the water inlet can be equal to the cross-sectional area of the water outlet, thereby maximizing the drainage efficiency of the floor drain core while meeting the sealing requirements.

[0057] See also Figure 8 In some embodiments, the lower end of the elastic hose 200 gradually shrinks to form a V-shaped connecting tube 202 , and the V-shaped connecting tube 202 is connected to the sealing lip 300 .

[0058] Among them, since the sealing lip 300 needs to be fitted and closed in the sealed state, in order to provide the sealing lip 300 with an opening and closing deformation space, part of the flexible hose is a V-shaped V-shaped connecting tube 202, so as to ensure that the sealing lip 300 has sufficient elastic deformation space when it is opened and unfolded. In addition, after being stretched open, the V-shaped connecting tube 202 can also provide the sealing lip 300 with a restoring and rebounding elastic force, so as to ensure that the sealing lip 300 can shrink and close normally later.

[0059] See also Figure 8 Preferably, the elastic hose 200 also includes a water receiving straight pipe 201 , the upper end of the water receiving straight pipe 201 is connected to the mounting ring 100 , and the lower end of the water receiving straight pipe 201 is connected to the V-shaped connecting pipe 202 .

[0060] Among them, since the sealing lip 300 is opened under the action of wastewater, it takes a certain amount of time for it to change from a closed state to an open state. If the distance between the water inlet of the floor drain core and the sealing lip 300 is too short, the sealing lip 300 may not be able to discharge the wastewater in time, resulting in wastewater overflow. By setting part of the pipe fittings of the elastic hose 200 as a water receiving straight pipe 201, the overall length of the floor drain core can be increased, the distance between the water inlet of the floor drain core and the sealing lip 300 can be extended, and the wastewater can be guided to be discharged smoothly from the sealing lip 300, reducing overflow and ensuring smooth drainage.

[0061] In some embodiments, the mounting collar 100 and the elastic hose 200 are made of silicone material.

[0062] First, because silicone is an excellent waterproof material, it can maintain stable waterproof performance during long-term use and will not age or crack over time. Therefore, the mounting ring 100 and the elastic hose 200 made of silicone material have good water resistance and waterproof performance.

[0063] Secondly, because silica gel has good corrosion resistance to most acids, alkalis and organic solvents, it can be used for a long time in various chemical environments without being damaged. Therefore, the mounting ring 100 and the elastic hose 200 made of silica gel material have good corrosion resistance and chemical stability.

[0064] Thirdly, since silica gel has good elasticity and flexibility and can be deformed according to needs without being easily broken or deformed. This enables the silica gel floor drain core to closely fit the floor drain water outlet, forming an effective seal. Therefore, the mounting collar 100 and the flexible hose 200 made of silica gel material have good elasticity and flexibility.

[0065] Fourthly, since silica gel can maintain elasticity and performance in the temperature range of -60°C to 250°C, this means that the silica gel floor drain core can work properly under various temperature conditions. Therefore, the mounting collar 100 and the flexible hose 200 made of silica gel material have good high and low temperature resistance.

[0066] Fifthly, since the surface of silica gel is smooth, therefore, the mounting collar 100 and the flexible hose 200 made of silica gel material are not easily adhered with dirt, which can effectively avoid the influence of dirt on the sealing performance of the floor drain core.

[0067] In addition, besides the above advantages, there will be an aging problem for silica gel after long-term use. The aging, hardening or cracking of silica gel will lead to a decline in the sealing performance of the floor drain core. Therefore, after long-term use, it is necessary to replace according to the silica gel state of the floor drain core to ensure that the floor drain core can work effectively.

[0068] Preferably, the mounting collar 100 and the flexible hose 200 are integrally formed.

[0069] Among them, for the mounting collar 100 and the flexible hose 200 made of silica gel material, designing the mounting collar 100 and the flexible hose 200 as an integrally formed structure has the following advantages: simplifying the manufacturing process, the integral forming process is relatively simple, and the overall required contours, holes, surface treatments, etc. of the mounting collar 100 and the flexible hose 200 can be completed in one mold, thus greatly reducing the production time and cost; improving the accuracy and repeatability, the integral forming process can improve the production accuracy and repeatability of the silica gel mounting collar 100 and the flexible hose 200, ensuring that the quality and performance of each product reach the same standard; being firm and solid, the integrally formed structure makes the silica gel floor drain core more firm and solid, capable of withstanding greater pressure and impact force, and improving the service life; reducing the cost, compared with the traditional split structure, the integrally formed silica gel floor drain core does not require additional assembly and connection processes, reducing the production cost.

[0070] Specifically, the integral forming process of the mounting collar 100 and the flexible hose 200 made of silica gel material can adopt a silica gel extrusion forming process or a silica gel injection molding process.

[0071] Figures 11 to 12 For the structural schematic diagram of the floor drain provided by the embodiment of the present application, refer to Figures 11 to 12, in some embodiments, the floor drain includes a floor drain main body 500 and the above-mentioned floor drain core. A first installation step 501 is provided on the floor drain main body 500;

[0072] Among them, the floor drain main body 500 is installed at the water inlet of the sewer pipe 600. The installation collar 100 is installed in cooperation with the first installation step 501, so that the floor drain core is hoisted in the sewer pipe 600.

[0073] In this embodiment, by providing the first installation step 501 on the floor drain main body 500, the floor drain core can be conveniently installed on the floor drain main body 500, and the installation position of the floor drain core can be ensured to be accurate.

[0074] Refer to Figure 13 , in some embodiments, a floor drain cover 400 is provided at the top of the floor drain main body 500, and a plurality of filter holes 401 are arranged on the floor drain cover 400.

[0075] Among them, the floor drain cover 400 provided with the filter holes 401 can block dirt and sundries from entering the sewer pipe 600. In places such as the kitchen or bathroom, food residues, hair and other sundries often fall on the ground. Without the filtering function of the floor drain cover 400, these sundries will enter the drainage pipe, which may cause the floor drain core to be blocked by dirt or sundries and cause problems such as sewage backflow.

[0076] Refer to Figure 12 , preferably, a second installation step 502 is provided on the floor drain main body 500, and the floor drain cover 400 is installed in cooperation with the second installation step 502.

[0077] Among them, by providing the second installation step 502 on the floor drain main body 500, the floor drain cover 400 can be conveniently installed on the floor drain main body 500, and the installation position of the floor drain cover 400 can be ensured to be accurate.

[0078] Preferably, the floor drain main body 500 and the floor drain cover 400 are made of metal materials.

[0079] Among them, the metal material has excellent anti-corrosion performance. The floor drain is an important facility connecting the bathroom and the sewer, often exposed to sewage and humid environments, so anti-corrosion performance is crucial. Metal materials such as copper and stainless steel have excellent anti-corrosion performance, are not easily corroded, cracked, deformed or aged, and can ensure the long-term stability and service life of the floor drain. Secondly, the metal material has excellent durability. Compared with other materials, the floor drain made of metal material has a longer service life. The strength and toughness of the metal material enable it to withstand long-term use and the erosion of sewage, and are not easily broken or cracked. In addition, some metal materials such as copper also have antibacterial properties, which can prevent the growth of bacteria and mold and keep the bathroom clean. Thirdly, the metal material also has a high aesthetic degree. The surface of the metal floor drain can be polished, sprayed, oxidized and other treatments to give it different textures and colors. For example, the copper floor drain has a warm and elegant texture, which can highlight the overall aesthetic degree and style of the bathroom. The stainless steel floor drain has a smooth and bright surface and a high-class texture, which can well integrate into the modern home decoration style.

[0080] In addition, the metal material also has good environmental protection and recyclability. The metal material is non-toxic and harmless, will not pollute the water quality, and meets the modern family's requirements for environmental protection and health. At the same time, the metal material can be recycled and reused, reducing resource waste and environmental pollution. In summary, the metal material is an ideal choice for making floor drains due to its excellent anti-corrosion performance, excellent durability, high aesthetic degree, good environmental protection and recyclability.

[0081] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0082] Those skilled in the art will easily think of other implementation schemes of this application after considering the specification and practicing the utility model disclosed here.
