Description

Technical Field

[0001] The present invention relates to the technical field of pipe fittings, and more specifically, to a dual-channel outlet pipe fitting and a water outlet system for a household water supply pipeline. Background Art

[0002] A variety of components are provided in the household water supply pipeline, such as a pre-filter, a ball valve, a globe valve, a microbubble generator, etc. These commonly used pipeline components basically have only one or zero channels for external communication. For example, the pre-filter has only one sewage discharge channel for discharging sewage except for the two ends connected to the pipeline ports, the microbubble generator has only one air inlet channel connected to the outside, and the antifreeze valve has only one drainage channel connected to the outside; when a certain household water supply pipeline component needs to open one or two external channels simultaneously or as required, the existing technologies and structures do not have this function. Therefore, the solution for a household water supply pipeline component to simultaneously open a dual channel is a technical problem that needs to be solved by those skilled in the art.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0055] In addition, if terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0056] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0057] As Figures 1 to 3 shown ( Figure 3 the dotted line in [ ] shows the water flow channel, and the arrow shows the water flow direction), the embodiments of the present invention provide a dual-channel outlet water pipe fitting 100 for a water supply pipeline, including a first channel component 110, a second channel component 130, and a tubular connector 150;

[0058] The first channel component 110 has a first water flow channel 101 and a first valve 120 for realizing the disconnection or unblocking of the first water flow channel 101;

[0059] A second water flow channel 102 communicating with the first water flow channel 101 is formed between the outer wall of at least a part of the first channel assembly 110 and the inner wall of the tubular connector 150;

[0060] The second channel assembly 130 has a third water flow channel 103, a fourth water flow channel 104, and a second valve 140 for realizing the disconnection or unblocking of the fourth water flow channel 104;

[0061] The first water flow channel 101 communicates with the third water flow channel 103, and the second water flow channel 102 communicates with the fourth water flow channel 104.

[0062] For the dual-channel water outlet fitting 100 of the water supply pipeline provided by the present invention, the first water flow channel 101 and the third water flow channel 103 communicate to form a water flow channel A, and the second water flow channel 102 and the fourth water flow channel 104 communicate to form a water flow channel B. By setting the first valve 120 and the second valve 140, the opening or closing of the water flow channel A or B can be controlled. For example, when the first valve 120 is opened, the water flow channel A is unblocked, and when the second valve 140 is opened, the water flow channel B is opened. Therefore, the dual-channel water outlet fitting 100 of the water supply pipeline provided by the embodiments of the present invention is integrated on the household water supply pipeline, and can realize the separate and independent adjustment of the opening and closing of the two channels, and can realize the opening or closing of one or both of the two channels. Moreover, the water outlet fitting can be integrated in an external connection hole. Such a design has a simple structure, is convenient for processing and forming, occupies less position for the channels, and has a beautiful appearance.

[0063] Specifically, there are 4 specific ways to open and close the channels of the dual-channel water outlet fitting 100 of the water supply pipeline, such as Figure 3 shown, both the water flow channels A and B are unblocked; as Figure 4 shown, both the water flow channels A and B are blocked; as Figure 5 shown, the water flow channel A is unblocked and the water flow channel B is blocked; as Figure 6 shown, the water flow channel A is blocked and the water flow channel B is unblocked.

[0064] As Figures 7 to 11 shown, in an optional embodiment, the first channel assembly 110 includes a first valve 120 and a dual-channel connector 111; the first valve 120 includes a first housing 121, a sensitive element 122, and a push rod 123;

[0065] The sensitive element 122 is disposed within the first housing 121. One end of the push rod 123 is located within the first housing 121 in contact with the sensitive element 122, and the other end extends out of the first housing 121. The dual-channel connector 111 has a first cavity 112 and a second cavity 113 that communicate with each other. The first cavity 112 and the second cavity 113 are connected through a water passage hole 114. The first housing 121 is connected to the dual-channel connector 111 corresponding to the first cavity 112, and there is a water passage gap 115 at the connection between the two that allows water to pass through. The other end of the push rod 123 is located within the first cavity 112. The sensitive element 122 is an element whose volume automatically changes with changes in environmental conditions. When the volume of the thermal-sensitive element increases, it can push the push rod 123 so that the other end of the push rod 123 abuts against the water passage hole 114 to close the water passage hole 114 (as Figure 7 shown). When the volume of the thermal-sensitive element decreases, it can pull back the push rod 123 to connect the first cavity 112 and the second cavity 113, that is, the first water flow passage 101 is unblocked (as Figure 8 shown).

[0066] The unblocking of the first water flow passage 101 can achieve the unblocking of the water flow passage A. Therefore, the specific setting of the first valve 120 can achieve the automatic unblocking or closing of the water flow passage A according to changes in the surrounding environment.

[0067] Furthermore, the sensitive element 122 is a thermal-sensitive element. That is, when the water flow temperature within the pipe fitting changes or the temperature around the pipe fitting changes, the first valve 120 can achieve automatic opening and closing.

[0068] Furthermore, the thermal-sensitive element is paraffin. That is, when the temperature of the environment where the pipe fitting is located is relatively high (above 4 degrees Celsius), when the paraffin is in a molten state, the volume of the paraffin is relatively large and it pushes the push rod 123 to block the water passage hole 114, and the first valve 120 is closed. At this time, the water flow passage A is in a closed state. When the temperature of the environment where the pipe fitting is located is relatively low (below 4 degrees Celsius), when the paraffin is in a solid state, the volume of the paraffin is relatively small, and it pulls back the push rod 123 to release the blockage of the water passage hole 114. At this time, the water flow passage A is in an open state. When the thermal-sensitive element is paraffin, when the temperature of the pipe fitting environment is too low, it can achieve the automatic opening of the water flow passage A. In the case of water flow, it will effectively improve the situation of water freezing in the pipeline and achieve a good anti-freezing effect.

[0069] Optionally, a first sealing washer 116 is provided at the end of the push rod 123 away from the sensitive element 122. The setting of the first sealing washer can ensure better tightness when the first valve 120 is closed.

[0070] Optionally, the first housing 121 includes a receiving portion 121a and a connecting portion 121b. The receiving portion 121a and the connecting portion 121b are snap-fitted to each other, and a sealing ring 161 is provided therebetween. The sensitive element 122 is filled in the receiving portion 121a, and the push rod 123 is disposed in the connecting portion 121b. A sealing ring 161 is sleeved on the outer wall of one end of the push rod 123 close to the sensitive element 122, and the outer periphery of the sealing ring 161 sleeved on the outer wall of the push rod 123 abuts against the inner wall of the connecting portion 121b.

[0071] Further, one end of the connecting portion 121b is provided with a plurality of connecting blocks 121c in a circle. The inner wall of the first cavity 112 in the double-channel connector 111 is provided with internal threads, and the outer walls of the plurality of connecting blocks 121c are provided with external threads. The plurality of connecting blocks 121c are threadedly connected to the double-channel connector 111, and the gaps between adjacent connecting blocks 121c communicate with the outside of the water supply pipeline double-channel outlet pipe fitting 100.

[0072] Optionally, as Figures 12 to 17 shown, the second channel assembly 130 includes a second housing 131 and a second valve 140; the second valve 140 includes a switch assembly 141 and a valve ball 142.

[0073] The second housing 131 communicates with the tubular connector 150. The second housing 131 has a valve ball mounting cavity 132. The double-channel connector 111 passes through the tubular connector 150 and enters the second housing 131 to communicate with the valve ball mounting cavity 132. The second housing 131 is provided with a water outlet 133. The tubular connector 150, the gap between the valve ball 142 and the valve ball mounting cavity 132, and the water outlet 133 are sequentially communicated; a second water flow channel 102 is formed between the tubular connector 150 and the double-channel connector 111. The second housing 131 has a water flow cavity 134 communicating with the second water flow channel 102. The switch assembly 141 is connected to the valve ball 142. The valve ball 142 is provided with a ball inner channel 143. By rotating the switch assembly 141 to drive the valve ball 142 to rotate, the valve ball 142 can be in an open state and a closed state. In the open state, one end of the ball inner channel 143 communicates with the water outlet 133, and the other end communicates with the water flow cavity 134 to form a fourth water flow channel 104 (as Figure 13 shown, the dotted line in the figure indicates the water flow cavity 134); in the closed state, the spherical surface of the valve ball blocks the end of the water flow cavity 134 to interrupt the communication (as Figure 12 shown).

[0074] Optionally, the second housing 131 is provided with a first connecting short pipe 135. The first connecting short pipe 135 is inserted into the tubular connector 150 and threadedly connected to the inner wall of the tubular connector 150. A sealing ring 161 is provided between the first connecting short pipe 135 and the tubular connector 150.

[0075] Optionally, the second housing 131 includes a cover body 136 and a housing main body 137. The cover body 136 is connected to the tubular connecting body 150, and the valve ball 142 is disposed within the housing main body 137;

[0076] A connecting ring 136a is disposed within the cover body 136. The outer wall of the connecting ring 136a is connected to the inner wall of the cover body 136 through a plurality of connecting ribs 136b. The housing main body 137 is provided with a second connecting short tube 137a, and the second connecting short tube 137a communicates with the valve ball mounting cavity 132. One end of the tubular connecting body 150 away from the sensitive element is inserted into the second connecting short tube 137a, and the second connecting short tube 137a is inserted into the connecting ring 136a and the two are threadedly connected.

[0077] The connection between the second connecting short tube 137a and the connecting ring 136a also realizes the connection between the cover body 136 and the housing main body 137. To achieve sealing, one of the two contact surfaces between the cover body 136 and the housing main body 137 is provided with a sealing groove 137f, and a sealing ring 161 is disposed within the groove.

[0078] Optionally, a first water chamber 136c is formed between the inner wall of the cover body 136 and the outer wall of the connecting ring 136a. A second water chamber 137c is disposed within the housing main body 137. The first water chamber 136c and the second water chamber 137c communicate to form a water passage chamber 134. A second sealing washer 137d is disposed at the end of the housing main body 137 corresponding to the water passage chamber 134. When the operating switch assembly 141 causes the spherical surface of the valve ball to block the end of the water passage chamber 134, the second sealing washer 137d can play a good sealing role to completely close the passage.

[0079] Optionally, an assembly hole 137b is formed in the housing main body 137. The switch assembly 141 passes through the assembly hole 137b and is connected to the valve ball 142. A third sealing washer 137e is disposed at the inner wall of the housing main body 137 where the assembly hole 137b is formed. The setting of the third sealing washer 137e can prevent the water inside the pipe fitting from leaking through the assembly hole 137b.

[0080] Further, the assembly hole 137b is a threaded hole. The switch assembly 141 includes a fitting 144, a valve stem 145, and a handle 146. The outer wall of the fitting 144 is provided with threads, and it is connected to the second housing 131 through the threaded hole. A through hole is formed in the middle of the fitting 144. One end of the valve stem 145 is connected to the valve ball 142, and the other end passes through the through hole and is connected to the handle 146. A sealing ring 161 is sleeved on the outer wall of the valve stem 145 to achieve sealing between the valve stem 145 and the fitting 144.

[0081] Further, the dual-channel water outlet pipe fitting 100 of the water supply pipeline further includes a drainage joint 138 and a drainage pipe 139. The joint of the drainage pipe 139 is connected to the second housing 131 and is arranged at the water outlet 133 and communicates with the water outlet 133. The drainage pipe 139 is connected to the drainage joint, and the water in the water flow channels A and B is discharged from the water outlet pipe.

[0082] An embodiment of the present invention also provides a dual-channel water outlet system 10 for a household water supply pipeline, including a dual-channel pipe body 11, a functional element 12, a mounting body 13, and the dual-channel water outlet pipe fitting 100 provided by the embodiment of the present invention.

[0083] Specifically, the dual-channel pipe body 11 has a first inlet 11a, a second outlet 11b, a second inlet 11c communicating with the first inlet 11a, and a first outlet 11d communicating with the second outlet 11b; the first inlet communicates with the mounting body 13, the first outlet 11d communicates with the functional element 12, and the functional element 12 is located inside the mounting body 13; the functional element 12 communicates with the first water flow channel 101, and the gap between the outer wall of the functional element 12 and the inner wall of the mounting body 13 communicates with the second water flow channel 102.

[0084] When the pipeline is not draining water, both the water flow channels A and B are in a non-communication state, and the water flow path is to enter the pipe fitting from the first inlet 11a, enter the functional element 12 through the second inlet 11c, and then flow out from the first outlet 11d and the second outlet 11b in sequence.

[0085] Further, the functional element 12 is a pre-filter or a microbubble generating mechanism. As shown in the figures of the present invention, the functional element 12 is a pre-filter. When the pre-filter needs to discharge sewage, by operating the handle, the water inside the pre-filter will be discharged from the water flow channel B to the pipeline, playing a role in sewage discharge. Therefore, the dual channels can be opened simultaneously without interference, can be closed simultaneously, and can also open one of the channels according to needs.

[0086] In summary, for the dual-channel water outlet pipe fitting provided by the present invention, the first water flow channel and the third water flow channel are connected to form a water flow channel A, and the second water flow channel and the fourth water flow channel are connected to form a water flow channel B. By setting the first valve and the second valve, it is possible to control the opening or closing of the water flow channel A or B. For example, when the first valve is opened, the water flow channel A is unobstructed, and when the second valve is opened, the water flow channel B is opened. Therefore, the dual-channel water outlet pipe fitting provided by the embodiment of the present invention integrated on the household water supply pipeline can independently adjust the opening and closing of the two channels separately; and this water outlet pipe fitting can be integrated in an external connection hole, and can realize the opening or closing of one or both of the two channels. Such a design has a simple structure, is convenient for processing and forming, occupies less space for the channels, and has a beautiful appearance.

[0087] In a preferred embodiment, when the first valve is set as a temperature-sensitive valve, the first water flow channel can be automatically adjusted according to temperature changes, effectively avoiding freezing of the pipeline due to too low temperature.

[0088] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
