Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage technology, and in particular to a drainage collector for a flat pipe. Background Technology
[0002] Some existing buildings use inter-floor drainage in their bathrooms, with horizontal branch pipes laid in the downstairs apartment without a water trap, making it easy for foul odors to back up, especially in summer. However, modifying the drainage pipes downstairs is very inconvenient, requiring communication with the downstairs owner, leaving residents feeling helpless. Moreover, the manifolds on the market are too tall to be installed on the same floor; and low-height manifolds for same-floor drainage are prone to backflow when draining from multiple points. Utility Model Content
[0003] To address the aforementioned problems, this utility model aims to provide a drainage collector for flat pipes, thereby solving the issues of high-low collectors lacking a water seal and being prone to backflow.
[0004] The technical problem solved by this utility model can be achieved by the following technical solution: a drainage collector for a flat pipe, comprising a collector body, a flow guide cover, and a water seal assembly. The flow guide cover is provided on the upper part of the collector body, and multiple drainage inlets are provided on the side of the collector body. The water seal assembly is provided on the lower part of the collector body. The water seal assembly includes a first water seal and a second water seal. The first water seal is connected to the lower part of the collector body, and the second water seal is connected to the first water seal. The second water seal covers the lower end of the first water seal.
[0005] The main body of the collector has four drainage inlets on its side, and the orientation of the four drainage inlets is offset from the center of the main body of the collector.
[0006] The drainage inlet is a flat inlet, and the drainage inlet is connected to a flat pipe.
[0007] A flower-shaped bracket is provided above the flow guide cover, and flower-shaped pieces are provided on the flower-shaped bracket.
[0008] An O-ring is provided between the main body of the collector and the water seal assembly.
[0009] The lower part of the collector body is provided with a placement port, and the placement surface of the placement port is inclined.
[0010] The second water seal is an outer cover of the lower end of the first water seal. The second water seal is a cup-shaped container with a post in the center. The first water seal is a hollow sleeve with a connecting rod at the top. The connecting rod has a hole in the center. The post is inserted into the hole to connect the second water seal to the first water seal.
[0011] Compared with existing technologies, this utility model has the following advantages: The collector's low height facilitates installation. During installation, the collector is installed above the existing drainage pipe, and a horizontal drainage pipe is installed in a groove on the same floor, connecting to the collector's inlet. The collector's inlet uses a flat pipe, reducing the groove depth and enabling drainage modification within the same floor. A water seal is provided at the bottom to prevent odors, and the water seal is easy to remove. When draining from multiple water points, the water flow is not misaligned, preventing backflow.

Detailed Implementation
[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0022] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] Combined with appendix Figures 1 to 8 As shown, this embodiment discloses a drainage collector for a flat pipe, including a collector body 4, a flow guide cover 3, a flower plate bracket 2, a flower plate 1, and a water seal assembly. The flow guide cover 3 is placed on the upper part of the collector body 4, and multiple drainage inlets 41 are provided on the side of the collector body 4. The water seal assembly is located at the lower part of the collector body 4. The water seal assembly includes a first water seal 6 and a second water seal 7. The first water seal 6 is connected to the lower part of the collector body 4, and the second water seal 7 is connected to the first water seal 6. The second water seal 7 covers the lower end of the first water seal 6.
[0024] A decorative tile support 2 is installed above the flow guide cover 3, and decorative tiles 1 are placed on the support 2. The support 2 is fixed to the tile layer with cement and cannot be removed. The flow guide cover 3 is placed above the collector body 4 and is removable. The flow guide cover 3 is funnel-shaped and guides the water flow from the four inlets on the collector body 4, preventing the water from flowing against each other and instead causing it to swirl downwards, thus avoiding backflow.
[0025] The drain inlet 41 is a flat opening, which connects to a flat pipe. Using a flat pipe reduces the depth of the groove, allowing for drainage modifications within the same floor. The flat pipe connects to water points such as sinks. Four drain inlets 41 are located on the side of the collector body 4. The orientation of these four drain inlets 41 is offset from the center of the collector body 4 to prevent water flow from colliding and to create swirling currents.
[0026] An O-ring 5 is provided between the collector body 4 and the water seal assembly. A placement port 42 is provided at the lower part of the collector body 4, and the placement surface of the placement port 42 is inclined. The upper edge of the first water seal component 6 rests on the placement surface. A sealing ring groove is provided on the placement surface, and the O-ring 5 is placed within the sealing ring groove.
[0027] The second water seal 7 covers the lower end of the first water seal 6. The second water seal 7 is a cup-shaped container with a central insertion post 71. The first water seal 6 is a hollow sleeve with a connecting rod 61 at its upper part. The connecting rod 61 has a central insertion hole 62. The insertion post 71 is inserted into the insertion hole 62 to connect the second water seal 7 to the first water seal 6. A nut is threaded onto the top of the insertion post 71. After the insertion post 71 is inserted into the insertion hole 62, its top protrudes out of the insertion hole 62. The nut is then tightened, making the water seal easy to disassemble and assemble.
[0028] During installation, the collector is installed above the old drainage pipe 8, and a horizontal drainage pipe is installed in a groove on the same floor to connect to the inlet of the collector. The collector's low height facilitates installation. During installation, the collector is installed above the old drainage pipe 9, and a horizontal drainage pipe is installed in a groove on the same floor to connect to the inlet of the collector. The collector's inlet uses a flat pipe, which reduces the groove depth and allows for drainage modification within the same floor.
[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
