Description

Technical Field

[0001] This utility model relates to an odor-proof core for drainers or floor drains, specifically a soft rubber sealing odor-proof core. Background Technology

[0002] Existing odor-proof cores mainly include those with flap, U-shaped, and duckbill silicone structures. Among them, the duckbill silicone odor-proof core is the most common. In order to ensure the sealing effect, the duckbill silicone drain outlet is kept closed in its natural state. It is difficult for the drain outlet to fully open to the maximum cross-sectional area. The clamped part is more likely to be blocked by dirt. When dirt blocks the drain outlet, it cannot be completely closed, and odors and other harmful gases can easily enter the room.

[0003] To address this issue, the applicant designed a combined odor-proof core, as disclosed in utility model publication number CN208309762U. The core includes a cylindrical body, characterized by: a connecting seat within the cylindrical body, with a drainage space between the connecting seat and the inner wall of the cylinder; a conical sealant fixed to the lower part of the connecting seat, with the outer edge of the lower edge of the sealant contacting the inner wall of the cylinder and sealing the lower end of the cylinder. This utility model employs a conical sealant sealing structure, with the upper end of the conical sealant fixed to the bottom of the connecting seat, and the lower edge of the conical sealant fitting against the inner wall of the shell to form a seal. It features fast drainage and a good sealing effect. However, the lower edge of the conical sealant in this odor-proof core will deform after a period of use, at which point the lower edge of the conical sealant may not fully adhere to the inner wall of the cylinder, thus affecting the sealing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a soft rubber sealing and odor-proof core. A restoring support ring is provided on the outer edge of the inclined soft rubber sealing plate. When a certain amount of water accumulates inside the odor-proof core, the gravity of the water causes the inclined soft rubber sealing plate to deform and shrink to achieve drainage. After drainage, the inclined soft rubber sealing plate automatically restores itself under the action of the original support ring and re-seals. The reset support ring can prevent the problem of the inclined soft rubber sealing plate deforming and failing to fit against the inner wall of the cylinder. It has the characteristics of reasonable structure, convenient assembly, reliability and durability.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] A soft rubber sealing and odor-proof core includes a cylinder, characterized in that: a sloping soft rubber sealing plate is provided on the inner wall of the cylinder near the lower port, and a connecting part is provided at the bottom of one side of the sloping soft rubber sealing plate. The sloping soft rubber sealing plate is fixed to the inner wall of the cylinder through the connecting part. When the sloping soft rubber sealing plate is in the unfolded state, it can seal the lower port of the cylinder. When there is a certain amount of water in the cylinder, the sloping soft rubber sealing plate deforms and contracts under the weight of the water, making the lower port of the cylinder open.

[0007] The connecting part is fixed to the inner wall of the cylinder by a tubular body; the outer wall of the tubular body matches the size of the inner wall of the cylinder, and the tubular body is connected to the inner wall of the lower end of the cylinder.

[0008] The inner wall of the lower port of the cylinder is provided with internal threads, and the outer wall of the tubular body is provided with external threads. The tubular body is screwed onto the inner wall of the lower port of the cylinder by the threads; a radial screw groove is provided at the lower end of the tubular body.

[0009] An insertion groove is provided on the inner wall of the tubular body, and the connecting part is a connecting column. The connecting column is located at the bottom of the highest side of the inclined soft rubber sealing plate. The connecting column is inserted into the insertion groove, and the outer edge of the inclined soft rubber sealing plate is sealed to the inner wall of the tubular body.

[0010] A downwardly extending recovery support ring is provided on the outer edge of the inclined soft rubber sealing plate, and a transfer groove is provided on the recovery support ring at the position corresponding to the connecting column.

[0011] The height of the recovery support ring gradually increases from the lowest side to the highest side of the inclined soft rubber sealing plate.

[0012] The inclined soft rubber sealing plate and the recovery support ring are an integral structure.

[0013] This invention features a sloping soft rubber sealing plate at or near the lower end of the cylinder. Made of soft rubber, the plate seals against the inner wall of the cylinder under normal conditions by utilizing the tension of the rubber material itself. When there is a certain amount of water inside the cylinder, the weight of the water causes the sloping soft rubber sealing plate to deform and contract, thus creating a channel at the lower end of the cylinder. Simultaneously, a restoring support ring is provided on the outer edge of the sloping soft rubber sealing plate. This ring prevents the thin, deformed sloping soft rubber sealing plate from failing to fully recover and not fitting properly against the inner wall of the cylinder. The increased contact area with the inner wall of the cylinder further enhances the sealing effect. Attached Figure Description

[0018] like Figure 1-4As shown, a soft rubber sealing odor-proof core includes a cylindrical body 1. A handle 5 is provided at the upper end of the cylindrical body 1. An inclined soft rubber sealing plate 2 is provided on the inner wall of the cylindrical body 1 near the lower end. A connecting part is provided at the bottom of one side of the inclined soft rubber sealing plate 2. The connecting part is fixed to the inner wall of the cylindrical body by a tubular body 3. An insertion groove 31 is provided on the inner wall of the tubular body 3. The connecting part is a connecting post 21, which is located at the bottom of the highest side of the inclined soft rubber sealing plate 2. The connecting post 21 is inserted into the insertion groove 31. The outer edge of the inclined soft rubber sealing plate 2 is tightly sealed to the inner wall of the tubular body 3. The lower end of the cylinder 1 has an internal thread, and the outer wall of the tubular body 3 has an external thread. The tubular body 3 is screwed onto the inner wall of the lower end of the cylinder 1. A radial screw groove 32 is provided at the lower end of the tubular body 3. The outer wall of the tubular body 3 matches the size of the inner wall of the cylinder 1. The tubular body 3 is connected to the inner wall of the lower end of the cylinder 1. When the inclined soft rubber sealing plate 2 is in the unfolded state, it can seal the lower end of the cylinder 1. When there is a certain amount of water in the cylinder 1, the inclined soft rubber sealing plate 2 deforms and contracts under the weight of the water, making the lower end of the cylinder 1 open.

[0019] A downwardly extending recovery support ring 4 is provided on the outer edge of the inclined soft rubber sealing plate 2. The inclined soft rubber sealing plate 2 and the recovery support ring 4 are an integral structure. A transfer groove 41 is provided on the recovery support ring 4 at the position corresponding to the connecting column 21. The height of the recovery support ring 4 gradually increases from the lowest side to the highest side of the inclined soft rubber sealing plate 2.

[0020] This invention features a sloping soft rubber sealing plate at or near the lower end of the cylinder. The sloping soft rubber sealing plate is made of soft rubber material. A restoring support ring is also provided on the outer edge of the sloping soft rubber sealing plate. This restoring support ring increases the contact area with the inner wall of the cylinder or tubular body, resulting in a better sealing effect. Under normal conditions, when no force is applied, the sloping soft rubber sealing plate and the restoring support ring utilize the tension of the soft rubber material itself to achieve a seal by engaging the edges with the inner wall of the cylinder or tubular body. When a certain amount of water accumulates inside the odor-proof core, the gravity of the water causes the sloping soft rubber sealing plate to deform and shrink. At this point, the sloping soft rubber sealing plate cannot seal the lower end of the cylinder. The more water there is, the greater the deformation and the faster the drainage. After drainage, the sloping soft rubber sealing plate automatically recovers under the action of the original support ring and re-seals. The restoring support ring prevents the sloping soft rubber sealing plate from deforming and failing to adhere to the inner wall of the cylinder.

[0021] This invention utilizes the deformation and contraction of a sloping soft rubber sealing plate under stress to achieve drainage. The height of the restoring support ring 4 on the outer edge of the sloping soft rubber sealing plate gradually increases from the lowest side to the highest side. The lowest point of the sloping soft rubber sealing plate has the least support force, and it will deform and drain water first during deformation. As the water volume of the odor-proof core increases, the sloping soft rubber sealing plate will deform from bottom to top, increasing the drainage speed. In addition, this invention also sets the sloping soft rubber sealing plate 2 on the tubular body 3. The tubular body can be screwed or snapped onto the lower end of the cylinder, making installation and disassembly very convenient and with good versatility. Compared with the prior art, this invention has the characteristics of reasonable structure, convenient assembly, reliability and durability.
