Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and more specifically, to an elbow pipe fitting with an exhaust structure, and also to a drainage structure using the elbow pipe fitting. Background Technology

[0002] Currently, in drainage renovation projects, relocating the balcony drainage point is the most common option for most families to meet daily living needs. Balconies often have drainage facilities such as washing machines, sinks, and mop sinks. To prevent backflow of odors, the original developer often installed a water trap at the lower end of the drainage pipe at the designated drainage point. During daily use, multiple drainage facilities can cause a large instantaneous water flow in the drainage pipe, creating an air blockage with the original water seal in the water trap, leading to poor drainage, backflow, and other problems, causing inconvenience to users' daily lives.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an elbow pipe fitting and drainage structure with an exhaust structure, which can discharge the gas in the pipe during the drainage process, thus helping to improve the smoothness of drainage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bend pipe fitting with an exhaust structure, comprising a bend body and an exhaust pipe, wherein the bend body includes an interface one and an interface two located at both ends; the exhaust pipe is located outside the bend body and is integrally formed with the bend body, wherein the first end of the exhaust pipe is connected to the bend body, and the second end of the exhaust pipe extends away from the interface two.

[0006] The present invention is further configured such that an exhaust port is provided on the outer arc side of the elbow body, and the first end of the exhaust pipe is connected to the exhaust port.

[0007] The present invention is further configured such that a blind plate is fixedly connected to the second end of the exhaust pipe, and the blind plate seals the exhaust pipe.

[0008] The present invention is further configured such that an annular groove is formed at the connection between the outer periphery of the blind plate and the exhaust pipe, and the thickness of the annular groove is less than the thickness of the blind plate.

[0009] The present invention is further configured to include an extension pipe, which is located inside the elbow body and communicates with the exhaust port.

[0010] The present invention is further configured such that the extension tube extends toward the second interface, and the outer wall of the extension tube is directly opposite the first interface.

[0011] The present invention is further configured such that the first interface and the second interface can be mutually inserted and adapted, the first interface being a socket and the second interface being a plug, and the inner periphery of the first interface forming an annular positioning step.

[0012] This utility model also provides a drainage structure, including the elbow fitting as described above, and further including a drainage pipe one, a drainage pipe two, and an exhaust pipe. The drainage pipe one is connected to the interface one, the drainage pipe two is connected to the interface two, and the exhaust pipe is connected to the exhaust pipe.

[0013] The present invention is further configured such that the first interface of the elbow fitting is arranged horizontally, the second interface is arranged downwardly, and the exhaust pipe is arranged upwardly; the first drainage pipe and the exhaust pipe are partially covered by a paving layer.

[0014] The present invention is further configured such that the drainage pipeline includes a first drainage pipe, a drainage elbow, and a second drainage pipe. The first drainage pipe is arranged horizontally, the second drainage pipe is arranged vertically, the first drainage pipe and the second drainage pipe are connected by a drainage elbow, and the first drainage pipe is connected to an interface.

[0015] The present invention is further configured such that the exhaust pipeline includes an exhaust elbow one, an exhaust pipe one, an exhaust elbow two, and an exhaust pipe two; the exhaust pipe one is arranged horizontally, and the exhaust pipe two is arranged vertically; the exhaust pipe one is connected to the exhaust pipe through the exhaust elbow one, and the exhaust pipe one and the exhaust pipe two are connected by the exhaust elbow two.

[0016] In summary, this utility model has the following beneficial effects:

[0017] An exhaust pipe can create an exhaust branch on the outside of the elbow fitting. During drainage, water flows in from one interface and out from the other, and the air remaining in the pipe can be discharged upwards through the exhaust pipe, maintaining the air pressure balance in the pipe and achieving smooth and efficient drainage.

[0018] By installing an extension pipe inside the elbow body, the extension pipe can serve as a downward extension of the vent and vent pipe. The outer wall of the extension pipe can block the water flow from the interface, so that the water flow will not directly enter the vent and can prevent water from flowing back and overflowing from the vent and vent pipe.

[0019] By pre-installing a blind flange at the second end of the exhaust pipe, the exhaust pipe is sealed off. This pre-installed blind flange structure allows users to choose between using it as a regular elbow fitting or, if the blind flange is removed, as an elbow fitting with an exhaust system.

Detailed Implementation

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

[0030] Example 1

[0031] This embodiment discloses a bend pipe fitting 100 with a venting structure, refer to... Figures 1-3As shown, it includes an elbow body 1 and an exhaust pipe 4. The elbow body 1 includes an interface 2 and an interface 3 located at both ends. Generally, the interface 2 and the interface 3 are roughly in the shape of a right-angle bend, and the specific bending angle can be adjusted according to actual needs.

[0032] The exhaust pipe 4 is located outside the elbow body 1 and is integrally formed with the elbow body 1, using high-polymer plastic injection molding. The exhaust pipe 4 has a first end 41 and a second end 42, wherein the first end 41 is connected to the elbow body 1, and the second end 42 of the exhaust pipe 4 extends away from the interface 2 3.

[0033] The exhaust pipe 4 forms an exhaust branch on the outside of the elbow fitting 100. During drainage, water flows in from interface 1 2 and out from interface 2 3. The air remaining in the pipeline can be discharged upward from the exhaust pipe 4, maintaining the air pressure balance in the pipeline and achieving smooth and efficient drainage.

[0034] Reference Figure 3 As shown, an exhaust port 101 is provided on the outer arc side 102 of the elbow body 1. The first end 41 of the exhaust pipe 4 is connected to the exhaust port 101, enabling the elbow body 1 and the exhaust pipe 4 to be interconnected. The second end 42 of the exhaust pipe 4 extends away from the interface 2 3. When the elbow fitting 100 is installed, the interface 2 3 faces upward for drainage, and the second end 42 of the exhaust pipe 4 faces upward for exhaust.

[0035] Furthermore, to facilitate the connection between the elbow fitting 100 and the existing pipeline structure, interface 2 and interface 3 can be configured as structures capable of mutual insertion. An annular positioning step 21 is formed on the inner circumference of interface 2, which enables positioning of the insertion structure.

[0036] Among them, interface 2 is a socket and interface 3 is a spigot. The end pipe of drainage pipe 200 can be inserted and installed at interface 2, and interface 3 can be inserted and installed at the corresponding interface of drainage pipe 700, which facilitates the assembly of elbow fitting 100 with other pipe structures.

[0037] Example 2

[0038] This embodiment discloses another type of elbow fitting 100 with a venting structure, which is based on Embodiment 1 and further refers to... Figure 4 , Figure 5 Please provide a detailed explanation.

[0039] In this embodiment, the elbow fitting 100 further includes an extension pipe 6, which is located inside the elbow body 1. The elbow body 1, the exhaust pipe 4, and the extension pipe 6 are integrally formed. The extension pipe 6 communicates with the exhaust port 101 and is generally coaxially arranged with the exhaust pipe 4. The extension pipe 6 can serve as an extension of the exhaust pipe 4 extending into the inside of the elbow body 1.

[0040] The end of the extension pipe 6 facing away from the exhaust port 101 extends towards the interface 2 3, and the outer wall of the extension pipe 6 is directly opposite the interface 2. The extension pipe 6 can normally allow the exhaust port 101 and the exhaust pipe 4 to exhaust upwards, and the outer wall of the extension pipe 6 can block the water flow from the interface 2, so that the water flow will not directly enter the exhaust port 101, thus preventing the water flow from the exhaust port 101 and the exhaust pipe 4 from backflowing and overflowing.

[0041] Example 3

[0042] This embodiment discloses another type of elbow fitting 100 with a venting structure, which is based on Embodiment 1 or Embodiment 2, and further refers to... Figure 6 , Figure 7 Please provide a detailed explanation.

[0043] In this embodiment, a blind flange 5 is fixedly connected to the second end 42 of the exhaust pipe 4, which seals the exhaust pipe 4. During the manufacturing process, the blind flange 5 is integrally formed with the exhaust pipe 4, which can seal the second end 42 of the exhaust pipe 4, meaning that in the initial state, the exhaust pipe 4 cannot exhaust gas.

[0044] During installation, if a venting structure is required for the pipeline, the blind flange 5 can be opened to allow the vent pipe 4 to pass through, thus enabling venting. If a venting structure is not required, the blind flange 5 can remain open, and the elbow fitting 100 will still allow for normal drainage. The pre-set blind flange 5 structure allows users to choose between using it as a regular elbow fitting or opening the blind flange 5 to use it as an elbow fitting 100 with a venting structure.

[0045] Furthermore, an annular groove 51 is formed at the connection between the outer periphery of the blind flange 5 and the exhaust pipe 4. The thickness of the annular groove 51 is less than the thickness of the blind flange 5. The wall thickness of the annular groove 51 is relatively thin and its strength is relatively low, which makes it easier to open the blind flange 5.

[0046] Example 4

[0047] This embodiment discloses a drainage structure, referring to... Figure 8 As shown, it includes the elbow fitting 100 as in any of the above embodiments, and also includes a drainage pipe 200, a drainage pipe 700, and an exhaust pipe 300.

[0048] Drainage pipe 200 is connected to interface 2 as the water inlet of the drainage structure; drainage pipe 700 is connected to interface 3 as the water outlet of the drainage structure. Exhaust pipe 300 is connected to exhaust pipe 4 as the exhaust outlet of the drainage structure.

[0049] In this embodiment, the first interface 2 of the elbow fitting 100 is arranged horizontally, the second interface 3 is arranged downwards, and the exhaust pipe 4 is arranged upwards. Both the first drainage pipe 200 and the exhaust pipe 300 are partially arranged horizontally and covered by the covering layer 500, and some extend upwards to the upper side of the covering layer 500. In particular, the upper end of the exhaust pipe 300 needs to have a certain height to prevent water overflow at the upper end of the exhaust pipe 300.

[0050] Specifically, the drainage pipeline 200 includes a drainage pipe 201, a drainage elbow 202, and a drainage pipe 203. The drainage pipe 201 is arranged horizontally, and the drainage pipe 203 is arranged vertically. The drainage pipe 201 and the drainage pipe 203 are connected by the drainage elbow 202, and the drainage pipe 201 is connected to interface 2.

[0051] The exhaust pipe 300 includes an exhaust elbow 301, an exhaust pipe 302, an exhaust elbow 303, and an exhaust pipe 304. The exhaust pipe 302 is arranged horizontally, and the exhaust pipe 304 is arranged vertically. The exhaust pipe 302 is connected to the exhaust pipe 4 through the exhaust elbow 301, and the exhaust pipe 302 and the exhaust pipe 304 are connected through the exhaust elbow 303.

[0052] During installation, the elbow body 1, drainage pipe 200, and exhaust pipe 300 are partially embedded in the cement mortar layer 400, and covered by the paving layer 500. Exhaust pipe 300's exhaust pipe 302 is embedded under the paving layer 500, while exhaust pipe 304 extends upwards and can be encased by the riser 600. Drainage pipe 200's drainage pipe 201 is embedded under the paving layer 500, while drainage pipe 203 extends upwards from the paving layer 500 to connect to the user's drainage pipes.

[0053] During drainage, water flows into drainage pipe 1 200, passes through elbow fitting 100, and then exits downward from drainage pipe 2 700. During drainage, the gas stored in the pipe (especially drainage pipe 2 700) can be discharged upward from exhaust pipe 4 and exhaust pipe 30, which can maintain the pressure balance in the pipe and facilitate smooth and efficient drainage.

[0054] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
