[0002] A joint is a component that connects different objects or parts. In the process of building water supply and drainage, pipes are used to transport water flow. In order to avoid blockage during water delivery, anti-blocking joints are needed for connection. Anti-blocking joints are joints that can prevent pipe blockage. They can prevent larger impurities in sewage from clogging the pipe during drainage.
[0003] When an existing anti-blocking joint of a building water supply and drainage pipe is in use, the filter screen is usually directly installed in the anti-blocking joint. After long-term use, the filtered impurities are directly blocked by the filter screen, which easily leads to accumulation and adhesion, thereby blocking the filter holes and affecting normal drainage. At the same time, when cleaning the impurities accumulated in the anti-blocking joint, it needs to be disassembled, which is a cumbersome process and greatly affects the water flow efficiency.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise clearly and specifically defined.
[0031] In the description of the present application, the term "for example" is used to mean "used as an example, illustration or description". Any embodiment described as "for example" in the present application is not necessarily to be construed as being more preferred or advantageous than other embodiments. In order to enable any technician in the field to implement and use the utility model, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the utility model obscure. Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.
[0032] In order to avoid disassembly and effectively extend the working time of the anti-blocking joint, this embodiment provides an anti-blocking joint for building water supply and drainage pipes, see Figure 1 , Figure 4, comprising a joint body 1, and an anti-fouling component 2 arranged in the joint body 1; more specifically, the water inlet end and the water outlet end of the joint body 1 are respectively connected with the water inlet pipe 3 and the water outlet pipe 4 through a connector 11; in the implementation process, the anti-fouling component 2 is arranged at the water outlet end of the joint body 1, and a dirt accommodating space 5 is formed between the outer surface of the anti-fouling component 2 and the inner wall of the joint body 1. When the water flows into the joint body 1 from the water inlet pipe 3 and flows toward the water outlet pipe 4, the water flows into the space 5 along the outer surface of the anti-fouling component 2 after entering from the water inlet end of the joint body 1. At the same time, the water flows into the interior of the anti-fouling component 2 through the first water passing hole 21 opened on the anti-fouling component 2 and then flows out from the water outlet end of the joint body 1, that is, the dirt in the water flow is intercepted by the anti-fouling component 2 in the dirt accommodating space 5, so that the filtered water flows through the water outlet pipe 4. In more detail, the first water passage holes 21 are arranged along the outer surface of the anti-fouling component 2, and the opening rate along the outer surface is not less than 80%, so as to increase the filtering area for sewage.
[0033] In order to enhance the anti-blocking effect, the anti-fouling component 2 is a cylindrical filter screen structure and is coaxially arranged with the joint body 1. More specifically, a connecting piece 6 is provided in the joint body 1 along its longitudinal direction, so that the anti-fouling component 2 is fixed on the connecting piece 6 to keep the anti-fouling component 2 always coaxially arranged with the joint body 1. Preferably, the outer edge of the connecting piece 6 can be fixedly connected to the inner wall of the joint body 1 to prevent water from flowing through the gap where the connection point between the two is located; in order to allow the water in the anti-fouling component 2 to flow into the water outlet pipe 4, a through hole is opened on the connecting piece 6, and the through hole is adapted to the anti-fouling component 2 (that is, the size of the through hole is adapted to the circular end face of the cylindrical filter screen); further, the connecting piece 6 can be a stainless steel connecting plate; during the flow of sewage, due to the cylindrical structure design and installation The direction is opposite to the direction of water flow, so that the dirt is first accumulated in the dirt holding space 5 on the side of the anti-fouling component 2 close to the water outlet pipe 4, thereby playing a certain anti-blocking effect, which is convenient for effectively extending the normal working time of the anti-blocking joint, reducing the cleaning frequency, and improving the water flow efficiency; at the same time, when the dirt in the sewage contacts the outer surface of the anti-fouling component 2, it will not be directly blocked compared with the existing baffle structure, but because the contact area becomes smaller, it will pass along the contact point with the anti-fouling component 2, and at the same time, the flow of water will form a circulation around the anti-fouling component 2 due to centrifugal force, so as to drive the dirt to rotate around the anti-fouling component 2. At this time, the dirt and the surface of the anti-fouling component 2 produce friction, which is convenient for cleaning most of the dirt stuck to the surface of the anti-fouling component 2, so that the anti-fouling component 2 has a certain self-cleaning ability.
[0034] In the specific implementation process, in order to discharge the dirt accumulated in the joint body 1, see Figure 1-Figure 4The anti-fouling component 2 also includes a dirt collection container 7 arranged at the outer bottom of the connector body 1, and a sewage discharge pipe 8 connected to the dirt collection container 7; the dirt collection container 7 has an opening at the top and is adapted to be connected to the sewage discharge port 12 at the bottom of the connector body 1, so that the dirt in the connector body 1 is discharged from the sewage discharge port 12 to the dirt collection container 7 and then discharged from the sewage discharge pipe 8. For the convenience of control and to avoid a large amount of liquid or dirt from being blocked in the dirt collection container 7, a sewage discharge solenoid valve 81 is provided on the sewage discharge pipe 8 near the liquid outlet end of the sewage collection container 7. The sewage collection container 7 is preferably in a funnel shape, and the end with a small opening is connected to the sewage discharge pipe 8 to facilitate the timely discharge of dirt from the sewage collection container 7 to avoid blockage; when there is no need to backwash the interior of the connector body 1, the sewage discharge solenoid valve 81 is always kept in a closed state. In this process, even if a small amount of water or liquid is retained in the sewage collection container 7, it does not affect the water flow from the water inlet pipe 3 to the filter and movement of the sewage intercepted by the connector body 1 to the water outlet pipe 4.
[0035] In the specific implementation process, see Figure 1-Figure 4 , this embodiment also includes a backwashing component 9, a backwashing pipe 91 in the backwashing component 9 is coaxially arranged with the anti-fouling component 2, and extends toward one end of the joint body 1 to communicate with the anti-fouling component 2 and one end of the water pipe 92, and the other end of the water pipe 92 extends out of the joint body 1. In order to enhance the stability of the backwashing pipe 91, the pipe sections of the backwashing pipe 91 and the water pipe 92 extending into the joint body 1 can be made of stainless steel; when it is necessary to backwash and clean the inside of the joint body 1, open the backwashing pipe 91 connected to the outside of the water pipe 92. The water flows through the water pipe 92 and the backwash pipe 91 in sequence, and then sprays into the connector body 1 through the second water holes 93 opened on the backwash pipe 91, and then sprays out from the first water hole 21 of the anti-fouling component 2 under the pressure and self-weight of the water flow to disperse the dirt in the dirt holding space 5, and at the same time, the dirt blocked in the first water hole 21 can be washed away, and finally the water and the dirt enter the dirt collection container 7 through the sewage outlet, and can be discharged from the sewage pipe 8 by opening the sewage discharge solenoid valve 81. Preferably, in order to make the water flow spray evenly and rinse the anti-fouling component 2 more cleanly, the second water holes 93 are opened at equal intervals along the length direction of the backwash pipe 91. Furthermore, the length of the backwash pipe 91 in the anti-fouling component 2 matches it. Preferably, the backwash pipe 91 has a small gap between one end of the water inlet pipe 3 and the end of the anti-fouling component 2, so that the second water hole 93 on the end face sprays water toward the corresponding surface of the anti-fouling component 2.
[0036] The utility model is achieved in this way:
[0037] 1. Install the joint body 1 between the water inlet pipe 3 and the water outlet pipe 4, and ensure that the anti-fouling component 2 is close to the side of the water outlet pipe 4;
[0038] 2. Turn on the water flow so that the water flows from the water inlet pipe 3 through the anti-blocking joint and the water outlet pipe 4 in sequence. In this process, the water flows into the interior of the anti-fouling component 2 from the first water hole 21 and enters the tail of the joint body 1 through the through hole on the connecting piece 6, and then enters the water outlet pipe 4, while the dirt in the water flow is blocked by the anti-fouling component 2 in the space 5 between it and the inner wall of the joint body 1;
[0039] 3. When the dirt blocking the connector body 1 needs to be cleaned after long-term use, open the backwash pipe 91, the water pipe 92, and the sewage solenoid valve 81, and deliver clean water to the connector body 1, first spray it into the anti-fouling component 2 through the second water hole 93, and then spray it out from the first water hole 21 to flush the dirt into the sewage collecting container 7, and finally discharge it from the sewage pipe 8. There is no need to disassemble the anti-blocking connector during the whole process, which is convenient, simple and efficient.
[0040] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
