Description

Technical Field

[0001] This invention relates to the field of anti-odor floor drain technology, specifically a water-sealed anti-odor device for vertical pipes. Background Technology

[0002] Currently, in indoor drainage systems such as kitchens and bathrooms, direct discharge from floor drains and backflow of odors in sink drain pipes are common. This is because existing pipe systems rely on S-bends at the bottom of the water inlet to prevent backflow. While this anti-backflow structure is effective to some extent, when the air pressure inside the pipe is high, or when odors are present above the S-bend, the sewer odors can still rise back up, producing unpleasant smells indoors and directly affecting people's lives. To solve this problem, a normally closed silicone self-sealing sleeve is available on the market. When draining water, the previously closed lower end opens under the impact of the water flow, and automatically closes when not draining. However, after a period of use, this type of anti-odor fitting will exhibit incomplete closure, failing to reliably prevent backflow and odors.

[0003] The existing method for preventing odors in floor drains is to add a flip-type opening and closing mechanism at the water outlet of the floor drain to achieve drainage and odor prevention. This structure is a mechanical opening and closing sealing structure. However, in actual use, since the drainage contains impurities and is not clean water, once impurities get stuck on the flip-type opening and closing mechanism, it cannot automatically close completely, thus losing its odor-preventing sealing performance.

[0004] In addition to the factors mentioned above, both products suffer from manufacturing precision and aging issues, thus their odor-proof reliability and stability cannot be guaranteed. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes a water-sealed odor prevention device for vertical pipelines.

[0006] The technical solution adopted in this invention is as follows: A water-sealed odor-proof device for vertical pipes includes a cylindrical body, a long baffle, a first short baffle, a second short baffle, a support column, an upper cover plate, and a lower cover plate. The long baffle, the first short baffle, and the second short baffle are fixedly connected by the support column. The upper ends of the long baffle and the first short baffle are flush, and the lower ends of the long baffle and the second short baffle are flush. The sum of the heights of the first short baffle and the second short baffle is greater than the height of the long baffle. The outer edges of the long baffle, the first short baffle, and the second short baffle are sealed and fixedly mounted on the sidewall of the inner hole of the cylindrical body, forming three spaces circumferentially within the inner hole of the cylindrical body. The upper cover plate seals and covers the large arc enclosed by the upper edges of the long baffle, the first short baffle, and the cylindrical body. On the notch, the small arc-shaped notch enclosed by the long baffle, the first short baffle, and the upper edge of the cylindrical body serves as the water inlet. The lower cover seals and covers the large arc-shaped notch enclosed by the long baffle, the second short baffle, and the lower edge of the cylindrical body. The small arc-shaped notch enclosed by the long baffle, the second short baffle, and the lower edge of the cylindrical body serves as the water outlet. Water flows from the water inlet into the water inlet cavity formed by the cylindrical body, the long baffle, the first short baffle, and the lower cover. When the water level exceeds the upper edge of the second short baffle, water flows from the upper edge of the second short baffle into the water outlet cavity formed by the cylindrical body, the long baffle, and the upper cover, and flows out from the lower outlet. The height difference between the lower edge of the first short baffle and the upper edge of the second short baffle is the water seal height.

[0007] Furthermore, an axial limiting ring is provided on the outer circular wall at the upper end of the cylindrical body.

[0008] Furthermore, an axial sealing ring is provided at the lower side of the axial limiting ring.

[0009] Furthermore, a floor drain with filtering capabilities is provided at the upper end of the axial limiting ring.

[0010] Furthermore, the long baffle, the first short baffle, and the second short baffle are evenly distributed circumferentially, and the long baffle, the first short baffle, and the second short baffle form three spaces of equal arc length along the circumferential direction of the inner hole of the cylindrical body.

[0011] Furthermore, a water-receiving ring is provided on the upper end face of the upper cover plate, and the lower end of the water-receiving ring is sealed to the upper outer circle of the cylindrical body.

[0012] Furthermore, a reducing water inlet pipe is sealed at the upper end of the water inlet ring, and one or more water inlet branch pipes are provided on the reducing water inlet pipe. This structure is particularly suitable for connecting double-chamber sinks in the kitchen to prevent odors from rising from the bottom pipe of the sink.

[0013] Furthermore, the sealing connection between the lower end of the water-receiving ring and the upper end of the cylindrical body is either a glued adhesive sleeve or a threaded connection.

[0014] Furthermore, the lower end of the cylindrical body is sealed with a variable diameter water outlet pipe.

[0015] Furthermore, the height of the first short baffle and the second short baffle are both 2 / 3 of the height of the long baffle, and serrated silicone sealing lips are provided at both the upper and lower ends of the cylindrical body.

[0016] The advantages of this invention are: The core objective of this invention is to achieve axial water seal to effectively prevent upward leakage of odors. A compartmentalized component, consisting of a long baffle, a first short baffle, a second short baffle, and a support column, is installed within a cylindrical body. The long baffle, the first short baffle, and the second short baffle are fixedly connected by the support column. The upper ends of the long baffle and the first short baffle are flush, and the lower ends of the long baffle and the second short baffle are flush. The sum of the heights of the first short baffle and the second short baffle is greater than the height of the long baffle. The long baffle, the first short baffle, and the second short baffle are fixedly integrated within the inner hole of the cylindrical body via the support column, forming three circumferential spaces within the inner hole of the cylindrical body. A top cover seals and covers the long baffle, the first short baffle, and the upper end of the cylindrical body. The large arc-shaped notch enclosed by the long baffle, the first short baffle, and the upper edge of the cylindrical body serve as the water inlet. The lower cover seals over the large arc-shaped notch enclosed by the long baffle, the second short baffle, and the lower edge of the cylindrical body. The small arc-shaped notch enclosed by the long baffle, the second short baffle, and the lower edge of the cylindrical body serves as the water outlet. Water flows from the inlet into the water inlet cavity formed by the cylindrical body, the long baffle, the first short baffle, and the lower cover. When the water level exceeds the upper edge of the second short baffle, the water flows from the upper edge of the second short baffle into the water outlet cavity formed by the cylindrical body, the long baffle, and the upper cover, and flows out from the lower outlet. The height difference between the lower edge of the first short baffle and the upper edge of the second short baffle is the water seal height.

[0017] With this structural design, an axial water seal can be formed along the axis inside the cylindrical body, replacing the traditional S-bend water seal structure, and the radial dimension is smaller.

[0018] An axial limiting ring is provided on the outer circular wall at the upper end of the cylindrical body, and an axial sealing ring is provided below the axial limiting ring. In this way, it can be directly inserted into the drain pipe below the floor drain, and a floor drain with a filtering function can be installed above the axial limiting ring.

[0019] A water-receiving ring is provided on the upper end face of the top cover plate. The lower end of the water-receiving ring is sealed to the upper outer circle of the cylindrical body. A reducing diameter water-receiving pipe is provided at the upper end of the water-receiving ring. One or more water-receiving branch pipes are provided on the reducing diameter water-receiving pipe. This structure is particularly suitable for connecting double-chamber sinks in the kitchen to prevent odors from rising from the bottom pipe of the sink.

[0020] This axial water seal structure can be directly fitted into the vertical drain pipe under the sink, overcoming the shortcomings of existing flexible rubber tube structures that are prone to aging and failure when flushing and automatically closing when water stops, and the poor sealing reliability of flip-top tongue-type drains that fail when blocked by debris. It completely solves the problem of poor odor prevention in traditional drains, ensuring clean air in the area. Compared to traditional simple drain cores, it forms a stable water seal chamber that can retain sufficient water to form an axial water seal section, using the sealing properties of water to prevent sewer odors from rising into the room, thus preventing odor diffusion at its source and improving indoor air quality.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The present application will be further described in detail below with reference to the accompanying drawings. Example 1: A water-sealed odor-proof device for vertical pipes, such as Figure 1-6 As shown, the device includes a cylindrical body 1, a long baffle 2, a first short baffle 3, a second short baffle 4, a support column 5, an upper cover plate 6, and a lower cover plate 7. The long baffle 2, the first short baffle 3, and the second short baffle 4 are fixedly connected by the support column 5. The upper ends of the long baffle 2 and the first short baffle 3 are flush, and the lower ends of the long baffle 2 and the second short baffle 4 are flush. The sum of the heights of the first short baffle 3 and the second short baffle 4 is greater than the height of the long baffle 2. The outer edges of the long baffle 2, the first short baffle 3, and the second short baffle 4 are sealed and fixed in the inner hole of the cylindrical body 1, forming three uniformly sized spaces along the circumference of the inner hole of the cylindrical body 1. The upper cover plate 6 seals and covers the large arc-shaped notch enclosed by the upper edges of the long baffle 2, the first short baffle 3, and the cylindrical body 1. The small arc-shaped notch enclosed by the baffle 2, the first short baffle 3, and the upper edge of the cylindrical body 1 is the water inlet 8. The lower cover 7 seals and covers the large arc-shaped notch enclosed by the long baffle 2, the second short baffle 4, and the lower edge of the cylindrical body 1. The small arc-shaped notch enclosed by the long baffle 2, the second short baffle 4, and the lower edge of the cylindrical body 1 is the water outlet 9. Water flows from the water inlet 8 into the water inlet cavity enclosed by the cylindrical body 1, the long baffle 2, the first short baffle 3, and the lower cover 7. When the water level exceeds the upper edge of the second short baffle 4, the water flows from the upper edge of the second short baffle 4 into the water outlet cavity enclosed by the cylindrical body 1, the long baffle 2, and the upper cover 6, and flows out from the lower outlet 9. The height difference between the lower end of the first short baffle 3 and the upper end of the second short baffle 4 is the water seal height.

[0031] When this water-sealed odor-proof device for vertical pipes is applied to floor drains for odor prevention, an axial limiting ring 10 is provided on the outer circular wall of the upper end of the cylindrical body 1, and an axial sealing ring 11 is provided at the lower side of the axial limiting ring 10. It is directly inserted into the drain pipe under the floor drain. The axial sealing ring 11 and the axial limiting ring 10 achieve axial limiting and sealing. The floor drain cover is placed on the upper port of the axial limiting ring 10, thereby filtering impurities in the flowing water. The axial water seal structure of this invention can effectively prevent odor leakage and cross-contamination.

[0032] When this water-sealed odor-proof device for vertical pipes is applied to the odor-proofing of kitchen and bathroom sink drainage systems, a water-receiving ring 12 is provided on the upper end face of the upper cover plate 6. The lower end of the water-receiving ring 12 is sealed to the upper outer circle of the cylindrical body (1), and the upper end of the water-receiving ring 12 is sealed to the variable diameter water-receiving pipe body. Multiple water-receiving branch pipes can be set on the variable diameter water-receiving pipe body. The drain pipe on the sink is sealed and installed on the corresponding drain branch pipe. For the current double-sink sink sink, three water-receiving branch pipes are provided on the variable diameter water-receiving pipe body.

[0033] In the two usage scenarios mentioned above, the sealing connection between the lower end of the water receiving ring 12 and the upper end of the cylindrical body 1 can be fixed by adhesive-bonded fitting or by threaded sealing between the lower end of the water receiving ring 12 and the upper end of the cylindrical body 1.

[0034] In this example, the heights of the first short baffle 3 and the second short baffle 4 are both 2 / 3 of the height of the long baffle 2, that is, the water seal height difference is 1 / 3 of the height of the long baffle 2.

[0035] To improve the sealing performance between the tubular body 1 and the corresponding insertion tube, a silicone lip serrated sealing structure 13 can be added to the outer circular wall at both ends of the tubular body 1.

[0036] There are many embodiments of the present invention, but the core is the structural scheme defined in claim 1. Any technical solution that adopts the same or equivalent functions as claim 1 is within the protection scope of the present invention.

[0037] The application scenarios of this invention are not limited; it can be used in any situation where there is a requirement to prevent reverse gas leakage.
