[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0033] The terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0034] Referring to "embodiment" or "embodiment manner" herein means that a specific feature, structure or characteristic described in connection with the embodiment or embodiment manner may be included in at least one embodiment of the present utility model. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0035] At present, the mechanical strength of plastic injection molded water pipe fittings such as water pipe joints, valve fittings, pipe bodies, etc. is relatively low, and it is easy to be damaged under high-pressure environments. Especially for the threaded connection parts, due to their structure, the threaded connection parts may be deformed or the threads may slip after a long time, making the above plastic injection molded water pipe fittings not reusable.

[0036] In view of this, the present utility model provides a runner structure 100, and the runner structure 100 can strengthen the structural strength of plastic injection molded water pipe fittings.

[0037] Please refer to Figure 1 and Figure 2 , a runner structure 100, comprising: a connecting member 10, the connecting member 10 includes a diversion portion 11, a connecting portion 12 and a water inlet 13, the connecting portion 12 is arranged at one end of the connecting member 10, the connecting portion 12 is arranged on the outer periphery of the diversion portion 11, a water inlet 13 is arranged on the side of the connecting member 10 away from the diversion portion 11, the water inlet 13 is used for connecting with a water pipe, the connecting portion 12 is provided with an external thread, and the water inlet 13 is provided with an internal thread;

[0038] The runner 20 includes at least one connection port 21, the connection port 21 is used for connecting with the connecting portion 12, and the connection port 21 is provided with an internal thread;

[0039] The length of the connecting portion 12 is greater than the length of the connection port 21. When the internal thread of the connection port 21 is connected to the external thread of the connecting portion 12, the diversion portion 11 is located inside the runner 20.

[0040] When the external thread of the connecting member 10 of the above runner structure 100 is connected to the internal thread of the runner 20, the connecting portion 12 extends into the connection port 21, so as to provide protection for the runner 20. Specifically, when water flows through the runner 20, the connecting member 10 is stressed first and then the runner 20 is stressed. In this way, the connecting member 10 can provide buffering for the runner 20, reduce the influence of water pressure on the mechanical strength of the injection molded water pipe fittings, and further reduce the probability of damage and thread slipping of the injection molded water pipe fittings due to their long-term exposure to high-pressure environments.

[0041] It can be understood that the diversion part 11 of the above-mentioned connector 10 is used to pass water flow. The connection part 12 is arranged on the diversion part 11 and is used to connect with the connection port 21 to realize the connection between the diversion part and the connection port 21. Specifically, an external thread is arranged on the connection part 12, and an internal thread is arranged on the connection port 21. By matching the internal thread of the connection part 12 with the external thread of the connection port 21, the connection between the connection part 12 and the connection port 21 can be realized; the water inlet 13 is used to connect with a water pipe to provide water flow for the flow channel 20. An internal thread is arranged on the water inlet 13, and through the internal thread, it can be connected with a pipeline to stably supply water from the pipeline into the flow channel 20. In this embodiment, the connector 10 provides a transition and buffer for the flow channel 20, and thus plays a protective role for the flow channel 20.

[0042] The external thread is arranged on the connection part 12 so that the connector 10 can extend into the flow channel 20. In this way, the connection part 12 can play a certain protective role for the connection port 21, because the connection part of the flow channel 20 is the weakest part of the flow channel 20. When the connector 10 extends into the flow channel 20, it can reduce the water pressure required by the connection port 21 of the flow channel 20, and thus reduce the probability of damage and thread slipping of the plastic water pipe fittings due to their long-term exposure to high-pressure environments.

[0043] It can be understood that, as Figure 1 shown, the length of the connection part 12 is L2, and the length of the connection port 21 is L1. The length of L2 is greater than the length of L1. The length of the connection part 12 is greater than the length of the connection port 21. In this way, after the connection part 12 and the connection port 21 are connected, the thread arranged on the connector 10 can be completely connected with the thread of the connection part 12. At the same time, the connection part 12 can also be completely covered by the connector 10 and can be completely connected with the connection part 12. In this way, it can play a comprehensive protective role for the plastic injection water pipe fittings, enabling the water flow to directly flow into the main body part of the plastic injection water pipe fittings, and thus reducing the damage to the connection port 21.

[0044] Please refer to Figure 2 and Figure 3 , in some embodiments, the connector 10 is made of a metal material.

[0045] It can be understood that the connector 10 is made of a metal material. Metal materials usually have high strength and toughness, can withstand large forces and pressures, can effectively resist the pressure of water flow, and can maintain their original shape after being subjected to the pressure of water flow without deforming due to water pressure. Moreover, they also have good corrosion resistance and can be used for a long time in harsh environments.

[0046] Please refer to Figure 2 and Figure 3 , in some embodiments, the flow channel 20 is composed of a metal layer 22 and a plastic layer 23, and the internal thread is arranged on the metal layer 22.

[0047] It can be understood that the outside of the flow channel 20 is a plastic layer 23, and the inside of the flow channel 20 is a metal layer 22. When the water flow in the flow channel 20 enters the flow channel 20, it acts on the metal layer 22 of the flow channel 20. The metal layer 22 of the flow channel 20 can effectively resist the pressure of the water flow and will not deform due to the water pressure. In this way, it can protect the plastic layer 23 outside the flow channel 20 and prevent the water pressure from directly acting on the plastic layer 23 to cause deformation of the flow channel 20 or damage to the flow channel 20. Setting the internal thread on the metal layer 22 not only facilitates the formation of the thread but also can improve the structural strength of the connection port 21 of the flow channel 20. After the internal thread at the connection port 21 is disassembled multiple times, the situation of the internal thread slipping is reduced, and the internal thread is still effective, thereby enhancing the structural strength of the internal thread and reducing the probability of the internal thread jamming.

[0048] Please refer to Figure 2 and Figure 3 , in some embodiments, the plastic layer 23 is the main body of the flow channel 20, and the metal layer 22 is arranged inside the plastic layer 23.

[0049] It can be understood that the main body part of the flow channel 20 is set as the plastic layer 23, that is, it is set by injection molding. Its main is the outer shape of the flow channel 20. The metal layer 22 is arranged outside the plastic layer 23, and the metal layer 22 adheres to the outer wall of the plastic layer 23. The metal layer 22 can effectively resist the pressure and impact force of the water flow and will not deform due to the water pressure. In this way, it can protect the plastic layer 23 outside the flow channel 20 and prevent the water pressure from directly acting on the plastic layer 23 to cause deformation of the flow channel 20 or damage to the flow channel 20.

[0050] Please refer to Figures 4 to 6 , in some embodiments, the flow channel 20 includes a flow channel water inlet 24, a water outlet 25 and a sewage outlet 26;

[0051] The axis of the flow channel water inlet 24 is collinear with the axis of the sewage outlet 26, the axis of the water outlet 25 is perpendicular to the axis of the flow channel water inlet 24, a first valve body 40 is arranged at the water outlet 25, and a second valve body 50 is arranged at the sewage outlet 26;

[0052] A filter element 30 is arranged on one side of the water outlet 25 close to the flow channel water inlet 24.

[0053] It can be understood that the flow channel 20 can include a flow channel water inlet 24, a water outlet 25 and a sewage outlet 26. Among them, the axis of the flow channel water inlet 24 is collinear with the axis of the sewage outlet 26, that is, the flow channel water inlet 24 and the sewage outlet 26 are arranged in the same flow channel 20. The axis of the water outlet 25 is perpendicular to the axis of the flow channel water inlet 24 or the axis of the sewage outlet 26, that is, the water outlet 25 is perpendicular to the flow channel water inlet 24.

[0054] In some embodiments, the flow channel structure further includes: a filter member 30, a first valve body 40, and a second valve body 50;

[0055] The filter member 30 is disposed on one side of the water inlet 24 of the flow channel close to the water outlet 25, the first valve body 40 is disposed at the water outlet 25, and the second valve body 50 is disposed at the sewage outlet 26.

[0056] It can be understood that a filter member 30 is provided on one side of the water outlet 25 close to the water inlet 24 of the flow channel. The filter member 30 is used to filter the water flowing from the water inlet 24 of the flow channel to the water outlet 25. The water flows in from the water inlet 24 of the flow channel. When the water flows through the filter element, the filter screen 31 can filter out large particle impurities in the water flow, and the large particles are retained in the pipeline under the influence of gravity. Then the filtered water flow enters the water purifier through the water outlet 25, so that large particle impurities can be prevented from entering the water purifier and damaging the filter element of the water purifier.

[0057] It can be understood that a first valve body 40 is provided at the water outlet 25, and a second valve body 50 is provided at the sewage outlet 26. The first valve body 40 and the second valve body 50 can be closed simultaneously, but generally they are not opened simultaneously. When water needs to be supplied to the water purifier, the first valve body 40 is opened and the second valve body 50 is closed. The water flow enters the flow channel 20 from the water inlet 24 of the flow channel, is filtered by the filter member 30, and then is discharged from the water outlet 25;

[0058] When the impurities filtered in the flow channel 20 need to be cleaned, the second valve body 50 is opened and the first valve body 40 is closed. The water flow enters the flow channel 20 from the water inlet 24 of the flow channel and then is discharged from the sewage outlet 26. After the water flow flushes the filter screen 31, the impurities in the flow channel 20 and the flow channel 20, the flushed sundries and water flow flow out through the sewage outlet 26, achieving the purpose of cleaning the filter member 30 and the filter screen 31.

[0059] Please refer to Figure 6 , in some embodiments, the second valve body 50 can be a plug 60 or an electromagnetic valve.

[0060] It can be understood that the second valve body 50 is used to open or seal the sewage outlet 26. When the sewage outlet 26 needs to be connected to a pipeline, the sewage outlet 26 can be provided as an electromagnetic valve.

[0061] In some cases, the sewage outlet 26 can collect the discharged water flow through some collection containers. In this case, the sewage outlet 26 can be set as a plug 60. It should be particularly noted that the plug 60 needs to be detachably arranged on the sewage outlet 26 to facilitate removing the plug 60 when cleaning the sewage outlet 26.

[0062] Please refer toFigure 7 , in some embodiments, the plug 60 is detachably disposed at the sewage outlet 26. The plug 60 includes a docking portion 61 and a sealing portion 62. The docking portion 61 is provided with an external thread, and the external thread is connected to the sewage outlet 26.

[0063] It can be understood that the plug 60 is detachably disposed on the sewage outlet 26 by means of threaded connection. Specifically, an internal thread is provided at the sewage outlet 26, and an external thread is provided on the plug 60. By connecting the internal thread of the sewage outlet 26 and the external thread on the plug 60, the plug 60 can be detachably disposed on the sewage outlet 26. The plug 60 includes a docking portion 61 and a sealing portion 62. Among them, the docking portion 61 is used to connect to the sewage outlet 26. The external thread on the plug 60 is provided on the docking portion 61, and the sealing portion 62 is disposed on the side of the plug 60 close to the docking portion 61. The sealing portion 62 is mainly used to seal the sewage outlet 26 so that the sewage outlet 26 does not leak.

[0064] Please refer to Figure 5 , in some embodiments, the filter element 30 includes: a filter screen 31 and a diaphragm 32, and the filter screen 31 and the diaphragm 32 are arranged in sequence along the water flow direction.

[0065] It can be understood that the filter element 30 includes a filter screen 31 and a diaphragm 32. The filter screen 31 and the diaphragm 32 are arranged in sequence along the water flow direction, that is, the water flow first flows through the filter screen 31 and then through the diaphragm 32, and then flows into the second flow channel 20. Among them, the filter screen 31 is used to filter larger particles, and the diaphragm 32 can filter other finer impurities, so that the filter element 30 has a better filtering effect.

[0066] Please refer to Figure 6 , in some embodiments, the flow channel structure 100 further includes a first flowmeter 251, a second flowmeter 241 and a controller;

[0067] The first flowmeter 251 is disposed at the water outlet 25, the second flowmeter 241 is disposed at the flow channel water inlet 24, the controller is disposed outside the flow channel 20, and both the first flowmeter 251 and the second flowmeter 241 are electrically connected to the controller.

[0068] It can be understood that the first flowmeter 251 is arranged at the water outlet 25, and the water output of the water outlet 25 can be counted when the water outlet 25 discharges water. The second flowmeter 241 is arranged at the water inlet 24 of the flow channel. When water flows into the water inlet 24 of the flow channel, the second flowmeter 241 counts the water volume of the water inlet 24 of the flow channel. The controller can be arranged at any position, and both the first flowmeter 251 and the second flowmeter 241 are electrically connected to the controller. The controller is used to compare the water flow rates of the first flowmeter 251 and the second flowmeter 241. When the difference in the water flow rates of the first flowmeter 251 and the second flowmeter 241 is large, it may indicate that part of the filter screen 31 is blocked, or there are other faults in the flow channel 20. The controller can issue an alarm. In this way, the sewage outlet 26 can be selected to be opened to clean the flow channel 20 and the filter element 30. When the controller still alarms after cleaning, the water flow rates of the water inlet 24 and the water outlet 25 of the flow channel can be restored to normal through maintenance or other means, avoiding other problems caused by water flow reasons.
