Description

Technical Field

[0001] The utility model relates to the field of sewer accessories, in particular to an anti-odor core. Background Art

[0002] At present, in order to prevent the odor from the sewer from entering the room, an anti-odor core that can be automatically sealed has appeared. Most of these anti-odor cores are now formed of elastic materials (such as plastic, silicone or rubber, etc.) to form an integrated, relatively connected and connected round tube part and flat tube part (for example: China's authorized announcement number CN209874018U, CN208965646U and CN216999997U and other patent documents disclosed), so the structure of this kind of anti-odor core is relatively soft.

[0003] When installing the deodorizing core, in order to ensure the sealing, the round tube part is usually tightly embedded in the drainage hole on the relevant drainage accessories. Among them, in order to ensure the smoothness of drainage, the inner wall of the round tube part is usually made relatively smooth; in addition, no other auxiliary disassembly structure for fingers to act on is provided on the round tube part. Therefore, when disassembling the deodorizing core, most people act on the inner wall of the round tube part with their fingers and move the deodorizing core upward. Since the round tube part is relatively soft and the inner wall is smooth, it is difficult for fingers to effectively exert force on the round tube part, making it difficult to separate the deodorizing core from the drainage hole, which easily leads to poor convenience in disassembling the deodorizing core.

[0004] At the same time, the shrinkage of the circular tube on this type of deodorizing core is very weak. When the temperature of the sewage passing through is very low, the circular tube is easily contracted by the cold, which may reduce the tightness of the circular tube or cause the circular tube to separate from the drainage hole, which may easily cause the deodorizing core to slide downward or even separate from the drainage hole and enter the sewer. Therefore, the stability of the installation and positioning of this type of deodorizing core is limited.

[0005] Therefore, it is very necessary to redesign the structure of the deodorizing core. Utility Model Content

[0006] The purpose of the utility model is to solve the above-mentioned problems and shortcomings and to provide a combined deodorizing core, which can facilitate the disassembly force to act stably and effectively when disassembling the combined deodorizing core, so that the deodorizing core can be easily separated from the drainage hole, thereby facilitating the disassembly of the deodorizing core; and it can also achieve a more stable and reliable positioning effect, and it is not easy to get loose even when the sewage temperature is very low, which can greatly improve the stability of the installation and positioning of the deodorizing core.

[0007] The technical solution of the utility model is achieved in this way:

[0008] A combined deodorizing core is characterized in that it comprises a soft cylinder body and a hard cylinder body, wherein the lower end of the soft cylinder body is contracted to form a flat mouth portion that can be closed automatically, a positioning convex ring is arranged on the upper end wall of the soft cylinder body, and an annular groove is arranged on the outer wall of the hard cylinder body, the hard cylinder body is embedded in the upper end of the soft cylinder body, and the annular groove is clamped on the positioning convex ring.

[0009] Preferably, a shifting protrusion is provided on the inner wall of the hard cylinder.

[0010] Preferably, the dialing protrusion is a vertically arranged protrusion.

[0011] Preferably, a lap convex ring is provided on the outer wall of the hard cylinder body, and the lap convex ring is arranged so as to protrude from the outer wall of the soft cylinder body.

[0012] Preferably, a clamped ring is integrally formed on the upper outer wall of the flexible cylinder body, and the clamped ring is clamped on the overlapping convex ring.

[0013] Preferably, the soft cylinder body includes an integrally formed cylindrical portion, a funnel portion, and at least three V-shaped patches, the positioning convex ring is arranged on the inner wall of the cylindrical portion, the funnel portion is butt-jointed to the lower port of the cylindrical portion, the funnel portion is provided with a plurality of lower water slits arranged around its vertical center line, and the lower water slits intersect at the vertical center line of the funnel portion, the number of the lower water slits is equal to the number of V-shaped patches, the V-shaped patches are sheets with a V-shaped horizontal cross-section, each V-shaped patch is arranged on the bottom surface of the funnel portion, and each V-shaped patch is arranged around the vertical center line of the funnel portion, the outer corners of each V-shaped patch are located on the vertical center line of the funnel portion, and the outer surfaces of adjacent V-shaped patches are also abutted together, a flat mouth portion is formed between the outer surfaces of adjacent V-shaped patches, and each flat mouth portion is located directly below each lower water slit.

[0014] Preferably, a plurality of convex ring portions are arranged on the outer circumferential surface of the cylindrical portion.

[0015] Preferably, a vertically arranged reinforcing convex strip is provided on the outer circumferential surface of the cylindrical portion, and the upper end of the reinforcing convex strip is connected to the convex ring portion, and the lower end of the reinforcing convex strip is connected to the outer sides of two adjacent V-shaped patches.

[0016] The utility model has the beneficial effects that the combined deodorizing core adopts the combined structure of the soft cylinder and the hard cylinder, and the positioning convex ring is arranged on the upper wall of the soft cylinder, which can effectively enhance the structural strength of the upper end of the soft cylinder, so that when the positioning convex ring is clamped in the annular groove on the hard cylinder, the soft cylinder and the hard cylinder can be stably and reliably assembled together, so the combined structure of the combined deodorizing core is very stable and reliable. This can make the soft cylinder effectively detach from the installation place with the hard cylinder during disassembly. Since the hard cylinder is embedded in the upper port of the soft cylinder, the hard cylinder can provide a stable and reliable place for the disassembly force, which can help to make the disassembly force stably and effectively act, so that the deodorizing core can be conveniently separated from the drain hole, and then it can help to improve the convenience of disassembling the deodorizing core. At the same time, the hard cylinder can play a very stable and reliable positioning effect on the soft cylinder, even when the sewage temperature is very low, it can also avoid the situation that the soft cylinder appears loose, which can help to greatly improve the stability of the installation and positioning of the deodorizing core.

[0025] like Figures 1 to 7As shown, the utility model describes a combined deodorizing core, comprising a soft cylinder body 1 and a hard cylinder body 2, wherein the lower port of the soft cylinder body 1 is contracted to form a flat mouth portion 10 that can be closed automatically, a positioning convex ring 11 is provided on the upper mouth wall of the soft cylinder body 1, and an annular groove 21 is provided on the outer wall of the hard cylinder body 2, the hard cylinder body 2 is embedded in the upper port of the soft cylinder body 1, and the annular groove 21 is clamped on the positioning convex ring 11.

[0026] The combined deodorizing core adopts a combined structure of a soft cylinder body 1 and a hard cylinder body 2, and a positioning convex ring 11 is arranged on the upper wall of the soft cylinder body 1, which can effectively enhance the structural strength of the upper end of the soft cylinder body 1, so that when the positioning convex ring 11 is clamped in the annular clamping groove 21 on the hard cylinder body 2, the soft cylinder body 1 and the hard cylinder body 2 can be stably and reliably assembled together, so the combined structure of the combined deodorizing core is very stable and reliable. This allows the soft cylinder body 1 to be effectively separated from the installation position along with the hard cylinder body 2 during disassembly.

[0027] Since the hard cylinder body 2 is embedded in the upper port of the soft cylinder body 1, the hard cylinder body 2 can provide a stable and reliable place for the disassembly force to act, which can help the disassembly force to act stably and effectively, thereby conveniently separating the deodorizing core from the drainage hole, and further helping to improve the convenience of disassembling the deodorizing core.

[0028] At the same time, the hard cylinder body 2 can play a very stable and reliable positioning effect on the soft cylinder body 1, and can prevent the soft cylinder body 1 from loosening even when the sewage temperature is very low, which can greatly improve the stability of the installation and positioning of the deodorizing core.

[0029] like Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the inner wall of the hard cylinder body 2 is provided with a toggle convex portion 22. The toggle convex portion 22 is provided to facilitate the finger action, so that the disassembly force can act on the combined deodorizing core more stably and reliably, thereby further improving the convenience of disassembly and maintenance of the combined deodorizing core.

[0030] like Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the convex part 22 is a vertically arranged convex piece, which is not only convenient for fingers to grasp, but also greatly reduces the influence of the convex part 22 on the water, thereby helping to further improve the applicability of the combined deodorizing core.

[0031] like Figure 7As shown, the corners of the moving protrusion 22 are arc transition corners 221, which can reduce the damage caused by scratches, thereby making disassembly and assembly safer.

[0032] like Figure 6 and Figure 7 As shown, a lap convex ring 23 is provided on the outer wall of the hard cylinder body 2, and the lap convex ring 23 is arranged so as to protrude from the outer wall of the soft cylinder body 1, and the lap convex ring 23 is located above the annular clamping groove 21. The lap convex ring 23 is not only conducive to lap positioning, but also provides a clamping position, which can play a more stable and reliable positioning role when installing and positioning the combined deodorizing core, thereby helping to further improve the reliability of the combined deodorizing core.

[0033] like Figure 6 and Figure 7 As shown, the toggle convex portion 22, the overlapping convex ring 23 and the hard cylinder body 2 are integrally formed of a hard plastic structure or a stainless steel structure. This ensures that the hard cylinder body 2 has a high structural strength, thereby playing a very stable and reliable positioning role, and thus can well meet the needs of actual use.

[0034] like Figures 1 to 5 As shown, a clamped ring 12 is integrally formed on the upper outer wall of the soft cylinder body 1, and the clamped ring 12 is clamped on the overlapping convex ring 23. The clamped ring 12 can provide flexible contact, which can help to make the overlapping or clamped part have high sealing performance, thereby helping to further improve the reliability and applicability of the combined deodorizing core.

[0035] like Figure 8 As shown, when installing and using, the drainage hole 201 of the drainage fitting 20 is made into a countersunk hole shape, so that the overlapping convex ring 23 or the overlapping convex ring 23 and the clamped ring 12 are overlapped in the large hole of the drainage hole, so that the requirements of overlapping positioning can be met. At the same time, when clamping positioning is adopted, the overlapping convex ring 23 or the overlapping convex ring 23 and the clamped ring 12 can be clamped by the relevant drainage fittings, so that the requirements of clamping positioning can be met. Thus, the requirements of actual use can be met. The above-mentioned drainage fittings can be floor drains, drainage pipes, etc.

[0036] like Figures 2 to 5As shown, the soft cylinder body 1 includes an integrally formed cylindrical portion 13, a funnel portion 14, and at least three V-shaped patches 15. The positioning convex ring 11 is arranged on the inner wall of the cylindrical portion 13, and the funnel portion 14 is docked on the lower end of the cylindrical portion 13. The funnel portion 14 is provided with a plurality of lower water seams 141 arranged around its vertical center line, and each lower water seam 141 intersects at the vertical center line of the funnel portion 14. The number of the lower water seams 141 is equal to the number of the V-shaped patches 15. The V-shaped patch 15 is a sheet material with a V-shaped horizontal cross section. Each V-shaped patch 15 is arranged on the bottom surface of the funnel portion 14 and arranged around the vertical center line of the funnel portion 14. The outer corners 151 of each V-shaped patch 15 are located on the vertical center line of the funnel portion 14. The outer surfaces 152 of adjacent V-shaped patches 15 are abutted together, and a flat mouth portion 10 is formed between the outer surfaces 152 of adjacent V-shaped patches 15. Each flat mouth portion 10 is located directly below each water discharge seam 141. Such a soft cylinder body 1 is not only convenient for water discharge, but also has an effective automatic closing and sealing effect, thereby having a very reliable deodorizing effect.

[0037] like Figure 5 As shown, a plurality of convex ring portions 131 are provided on the outer circumferential surface of the cylindrical portion 13. The provision of the convex ring portions 131 can improve the stability and sealing of the embedded installation, thereby helping to further improve the reliability and applicability of the combined deodorizing core.

[0038] like Figure 2 As shown, the outer circumferential surface of the cylindrical portion 13 is provided with a vertically arranged reinforcing ridge 132, and the upper end of the reinforcing ridge 132 is connected to the convex ring portion 131, and the lower end of the reinforcing ridge 132 is connected to the outer sides of two adjacent V-shaped patches 15. This can further improve the structural strength of the combined deodorizing core, thereby helping to further improve the durability of the combined deodorizing core.

[0039] like Figure 2 As shown, an identification portion 1321 is provided on the outer wall of the reinforcing convex strip 132. The identification portion 1321 is an identification convex portion or concave portion used to identify the product, such as: product name, merchant logo, trademark, other identification graphics, etc., so as to meet the identification requirements.

[0040] like Figures 1 to 5 As shown, the positioning convex ring 11, the clamped ring 12, the cylindrical portion 13, the funnel portion 14, the V-shaped patches 15, the convex ring portions 131 and the reinforcing convex strips 132 are integrally formed of soft plastic, silicone or soft rubber, etc., so that the effect of automatic closing and sealing can be stably achieved, thereby being able to well meet the needs of actual use.
