Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0047] like Figure 1 and Figure 2 As shown, a pipeline assembly 100 according to an embodiment of the present invention includes an outer pipe 110, a core rod 120, a sealing element, and a transition structure 114.
[0048] Specifically, the outer pipe 110 has a water outlet window 113 on its peripheral wall, which connects the outside and inside of the outer pipe 110. One end of the core rod 120 is located inside the outer pipe 110, and the core rod 120 can move between a first position and a second position along the axial direction of the outer pipe 110. When the core rod 120 is in the first position, the outer pipe 110 and the core rod 120 form a first water passage; when the core rod 120 is in the second position, the outer pipe 110 and the core rod 120 form a second water passage. A sealing element is located on the outer wall of the core rod 120 and fits against the inner wall of the outer pipe 110 to divide the internal space of the outer pipe 110 into multiple parts, allowing water to flow along the first or second water passage. Specifically, as shown... Figure 4 and Figure 7 As shown, the outer pipe 110 has a first channel 111 inside, and the water outlet window 113 is connected to the first channel 111. The first channel 111 is along the axial direction of the outer pipe 110 (e.g., Figure 4The mandrel 120 extends and penetrates both ends of the outer tube 110 in the direction indicated by the middle arrow a. One end of the outer tube 110 forms a water inlet 115, which is connected to a water source to supply water to the pipeline assembly 100. The mandrel 120 is inserted into the outer tube 110 from the other end. A sealing element is provided on the portion of the mandrel 120 located inside the outer tube 110. The sealing element fits against the peripheral wall of the first channel 111, thereby dividing the first channel 111 into multiple parts. The sealing element can be a rubber sealing ring. The outer wall of the mandrel 120 can be provided with a mounting groove extending circumferentially along the mandrel 120. The sealing element is embedded in the mounting groove, and a portion of the sealing element protrudes from the mounting groove to contact the inner wall of the outer tube 110 to fix the sealing element and reduce the friction between the sealing element and the mandrel 120 during the movement of the mandrel 120. When the core rod 120 moves between the first and second positions along the axial direction of the outer tube 110, the seal can move from one side of the water outlet window 113 to the other side.
[0049] The transition structure 114 is connected to the sidewall of the outlet window 113, so that the seal moving from one side of the outlet window 113 to the other side has at least a portion of its outer edge separated from the outlet window 113, thereby reducing the contact friction between the seal and the sidewall of the outlet window 113 and reducing the wear of the seal. It is understood that during the movement of the seal from one side of the outlet window 113 to the other, the seal contacts and rubs against the edge and sidewall of the outlet window 113, and the sidewall of the outlet window 113 often forms an angle with the inner wall of the exterior, making the seal prone to wear. Furthermore, part of the outer edge of the seal undergoes contact with the inner wall of the exterior, embedding into the outlet window 113, and then contact with the inner wall of the exterior again, causing repeated deformation of the seal and making it prone to fatigue damage. The transition structure 114 separates part of the outer edge of the seal from the water outlet window 113 during the process of the seal moving from one side of the water outlet window 113 to the other side, reducing the contact friction between the seal and the water outlet window 113, reducing the degree of repeated deformation of the seal, and extending the service life of the seal.
[0050] like Figure 5 and Figure 6 As shown, there can be multiple seals, including a first seal 125, a second seal 126, and a third seal 127. The core rod 120 moves between a first position and a second position, causing the outer tube 110 and the inner tube to form a first water passage or a second water passage. The second seal 126 moves along the axial direction of the outer tube 110 (as shown by arrow a in the figure) and can move from one side of the water outlet window 113 to the other side. Figure 5 As shown, when the core rod 120 is in the first position, a first water channel is formed between the outer tube 110 and the core rod 120. The first seal 125 and the second seal 126 are located on one side of the water outlet window 113, and the third seal 127 is located on the other side of the water outlet window 113. Figure 6 As shown, when the core rod 120 is in the second position, a second water channel is formed between the outer tube 110 and the core rod 120. The first seal 125 is located on one side of the water outlet window 113, and the second seal 126 and the third seal 127 are located on the other side of the water outlet window 113. Therefore, it can be understood that during the movement of the core rod 120 between the first and second positions, the second seal 126 passes through the location of the water outlet window 113 and rubs against the edge of the water outlet window 113 near the inside of the outer tube 110. The second seal 126 is prone to wear, resulting in a shortened service life of the second seal 126 and easy leakage of the pipeline assembly 100.
[0051] exist Figure 3 In the example, the water outlet window 113 is quadrilateral. Along the axial direction of the outer tube 110, the water outlet window 113 has opposing first sidewalls 1131 and second sidewalls 1132. When the core rod 120 moves from the first position to the second position, the second seal 126 rubs against the edges of the first sidewall 1131 and the second sidewall 1132 once each. That is, when the seal moves from one side of the water outlet window 113 to the other, it rubs against the edge of the water outlet window 113 at least twice. By providing the transition structure 114, when the seal moves from one side of the water outlet window 113 to the other, a portion of the outer edge of the seal is separated from the water outlet window 113, reducing the contact area between the first sidewall 1131 and the second sidewall 1132 and the seal, avoiding or reducing friction between the second seal 126 and the edge of the water outlet window 113, thereby improving the service life of the second seal 126.
[0052] According to the embodiment of the present utility model, the pipeline assembly 100, by providing a transition structure 114 connected to the side wall of the water outlet window 113, allows part of the outer edge of the seal to be separated from the water outlet window 113 during the process of the seal moving from one side of the water outlet window 113 to the other side, thereby reducing the contact friction area between the seal and the water outlet window 113, reducing the friction on the seal, extending the service life of the seal, and reducing the probability of failure of the pipeline assembly 100.
[0053] According to some embodiments of the present invention, the transition structure 114 is disposed inside the water outlet window 113, and the transition structure 114 divides the water outlet window 113 into at least two sub-windows, thereby preventing the seal from deforming into the water outlet window 113 and avoiding friction between the seal and the side wall of the water outlet window 113.
[0054] In some embodiments, in the axial direction of the outer tube 110, the outlet window 113 has opposing first sidewalls 1131 and second sidewalls 1132. A transition structure 114 is connected to both the first sidewalls 1131 and 1132. The seal can move along the transition structure 114 to move from one side of the outlet window 113 to the other. The transition structure 114 is connected to both the first sidewalls 1131 and 1132, forming an isolation area on the first sidewalls 1131 and 1132. When the seal moves from one side of the outlet window 113 to the other, the isolation area separates from the seal, reducing the contact area between the first sidewalls 1131 and 1132 and the seal, reducing the frictional force on the seal, and extending the service life of the seal.
[0055] One end of the transition structure 114 is connected to the first sidewall 1131. The portion where the first sidewall 1131 and the transition structure 114 are connected forms the aforementioned isolation area. The transition structure 114 and the first sidewall 1131 have at least one first connection point on the side near the interior of the outer tube 110. This reduces the length of the friction portion between the first sidewall 1131 near the interior of the outer tube 110 and the seal, thus reducing wear on the seal. The other end of the transition structure 114 is connected to the second sidewall 1132. The portion where the second sidewall 1132 and the transition structure 114 are connected forms the isolation area. The transition structure 114 and the second sidewall 1132 have at least one second connection point on the side near the interior of the outer tube 110, thereby reducing the length of the friction portion between the edge of the second sidewall 1132 near the interior of the outer tube and the seal, thus reducing wear on the seal. The transition structure 114 is located inside the water outlet window 113 and can act as a barrier, reducing the volume of the part of the seal embedded in the water outlet window 113 during movement, thereby reducing the degree of deformation of the seal as it approaches and moves away from the water outlet window 113.
[0056] like Figure 10As shown, according to some embodiments of the present invention, the transition structure 114 includes at least one rib 1141. One end of the rib 1141 is connected to the first sidewall 1131 to form a first connection point, and the other end of the rib 1141 is connected to the second sidewall 1132 to form a second connection point. The rib 1141 divides the water outlet window 113 into at least two sub-windows, suppressing deformation of the seal within the water outlet window 113. The location where the first sidewall 1131 connects to one end of the rib 1141 forms an isolation area. During the movement of the seal from one side of the water outlet window 113 to the other side, the seal is separated from this isolation area. The location where the second sidewall 1132 connects to the other end of the rib 1141 forms an isolation area. During the movement of the seal from one side of the water outlet window 113 to the other side, the seal is separated from this isolation area, thereby reducing wear on the seal. Furthermore, as the seal moves from one side of the outlet window 113 to the other, the ribs 1141 abut against the seal, thereby preventing the seal from deforming into the outlet window 113, reducing the contact area between the seal and the sidewall of the outlet window 113, and suppressing the degree of deformation of the seal. In some embodiments, there may be two or more ribs 1141, and the ribs 1141 are arranged in a direction perpendicular to the axis of the outer tube 110 (e.g., Figure 10 The distribution (as indicated by the middle arrow b) further reduces the area of friction between the first sidewall 1131, the second sidewall 1132 and the seal, thereby reducing the wear of the seal.
[0057] like Figure 8 As shown, in some embodiments, the transition structure 114 fills the water outlet window 113. The transition structure is connected to both the first sidewall 1131 and the second sidewall 1132, and the portions of the first sidewall 1131 and the second sidewall 1132 connected to the transition structure form an isolation area. The transition structure 114 has at least two through holes, making the transition structure 114 mesh-like. Specifically, the transition structure 114 is flat and has multiple through holes, making the transition structure 114 mesh-like. The mesh-like transition structure 114 divides the water outlet window 113 into multiple sub-windows. On the one hand, this reduces the friction length between the first sidewall 1131, the second sidewall 1132 and the seal, reducing the wear of the seal; on the other hand, it prevents the seal from deforming and embedding itself into the water outlet window 113 when it moves to the water outlet window 113, thereby reducing the degree of deformation of the seal when passing through the water outlet window 113.
[0058] like Figure 7 and Figure 8As shown, according to some embodiments of the present invention, the water outlet window 113 has a third sidewall 1133 and a fourth sidewall 1134 parallel to the axial direction of the outer pipe 110. The transition structure 114 includes a first arcuate surface 1142 and a second arcuate surface 1143. The first arcuate surface 1142 connects the third sidewall 1133 and the inner wall of the outer pipe 110, and the second arcuate surface 1143 connects the fourth sidewall 1134 and the inner wall of the outer pipe 110, making the connection between the third sidewall 1133, the fourth sidewall 1134 and the inner wall of the outer pipe 110 smoother. During the process of the seal moving from one side of the water outlet window 113 to the other side, the seal can move along the first arcuate surface 1142 and the second arcuate surface 1143, reducing the friction between the seal and the third sidewall 1133 and the fourth sidewall 1134, and reducing the wear of the seal.
[0059] like Figure 9 As shown, according to some embodiments of the present invention, the transition structure 114 is columnar and is disposed on the peripheral wall of the pipe body, extending towards the outside of the outer pipe 110. The water outlet window 113 is disposed at the end of the transition structure 114 away from the outer pipe 110. The transition structure 114 has a through hole connecting the interior of the outer pipe 110 and the water outlet window 113, so that the first sidewall 1131 and the second sidewall 1132 are both away from the interior of the outer pipe, forming an isolation area. The transition structure 114 forms a bend at the end near the outer pipe 110, making the transition structure 114 trumpet-shaped. A transition curved surface 1144 is formed between the inner wall of the transition structure 114 and the inner wall of the outer pipe 110. The seal can slide along the transition curved surface 1144, separating the seal from both the first sidewall 1131 and the second sidewall 1132. The isolation area is the first sidewall 1131 and the second sidewall 1132. Thus, when the core rod 120 moves between the first position and the second position, the seal can slide along the transition surface 1144 to approach or move away from the water outlet window 113, making the movement of the seal smoother and reducing the wear of the seal.
[0060] like Figure 4 and Figure 12As shown, according to some embodiments of the present invention, the outer tube 110 is provided with a first channel 111, and the water outlet window 113 is connected to the first channel 111. The first channel 111 extends along the axial direction of the outer tube 110 and passes through both ends of the outer tube 110. One end of the outer tube 110 forms a water inlet 115, which is connected to a water source to supply water to the pipeline assembly 100. The core rod 120 is inserted into the outer tube 110 from the other end. The core rod 120 is provided with a second channel 122 and a third channel 124. The core rod 120 is provided with a first connecting groove 123, a second connecting groove 129, and a water outlet 121. The second channel 122 passes through the end of the core rod 120 located in the first channel 111 and is connected to the first channel 111. The first connecting groove 123 is connected to the second channel 122 and is connected to the outside of the core rod 120. The outlet 121 connects to the outside of the core rod 120, the third channel 124 connects to the outlet 121, and the second connecting groove 129 connects to the third channel 124, and the second connecting groove 129 connects to the outside of the core rod 120. The first connecting groove 123 and the second connecting groove 129 are spaced apart and not directly connected to each other. The third sealing element 127 is located between the first connecting groove 123 and the second connecting groove 129. The second sealing element 126 is located on the side of the first connecting groove 123 away from the second connecting groove 129, and the first sealing element 125 is located on the side of the second sealing element 126 away from the second sealing groove.
[0061] like Figure 5 As shown in the diagram, the arrows indicate the direction of water flow. When the core rod 120 is in the first position, the first connecting groove 123 is connected to the water outlet window 113, and the first channel 111, the second channel 122, and the water outlet window 113 form a first water path, allowing water to flow along it. Specifically, when the core rod 120 is in the first position, the first connecting groove 123 is opposite to and connected to the water outlet window 113. The second seal 126 is located on the side of the water outlet window 113 near the inlet 115, and the third seal 127 is fitted against the inner wall of the first channel 111 to prevent water from flowing along the first channel 111 into the second connecting groove 129. Water flows from the inlet 115 into the first channel 111, then into the second channel 122, and from the first connecting groove 123 to the water outlet window 113, thus providing water for the user. It is understandable that when the core rod 120 is in the first position, the second connecting groove 129 is located in the first channel 111. A fourth sealing element 128 can be provided on the side of the second connecting groove 129 away from the first connecting groove 123. The fourth sealing element 128 fits against the inner wall of the first channel 111 to ensure the sealing of the pipeline assembly 100.
[0062] like Figure 6As shown, the arrows in the figure indicate the direction of water flow. When the core rod 120 is in the second position, the first connecting groove 123 and the second connecting groove 129 are connected through the first channel 111. The first channel 111, the second channel 122, the third channel 124 and the outlet 121 form a second water path, and water can flow along the second water path. Specifically, the end of the first channel 111 away from the inlet 115 forms a connecting section 112. When the core rod 120 is in the second position, the second seal 126 is located on the side of the outlet window 113 away from the inlet 115 to isolate the outlet window 113 from the first connecting groove 123. The first connecting groove 123 and the second connecting groove 129 are both connected to the connecting section 112. The third seal 127 is located inside the connecting section 112. The diameter of the connecting section 112 is larger than the diameter of the third seal 127, so that at least one part of the third seal 127 is not in contact with the inner wall of the connecting section 112. Thus, the first connecting groove 123 and the second connecting groove 129 are connected through the connecting section 112 of the first channel 111. The fourth seal 128 is located inside the connecting section 112 and is in contact with the inner wall of the connecting section 112 to ensure the sealing of the pipeline assembly 100. Water flows from the inlet 115 into the first channel 111, then into the second channel 122, and from the first connecting groove 123 into the connecting section 112. The water in the connecting section 112 flows into the third channel 124 through the second connecting groove 129, and finally flows out from the outlet 121 to be provided to the user.
[0063] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the pipeline assembly 100 further includes an elastic element 130. One end of the elastic element 130 is connected to the core rod 120, and the other end is connected to the outer tube 110. When the core rod 120 moves from the second position to the first position, the elastic element 130 can apply a force to the core rod 120 toward the second position. The elastic element 130 can be a column spring. One end of the elastic element 130 is connected to the outer tube 110, and the other end is connected to the inner core. When the core rod 120 moves from the second position to the first position, the elastic element 130 is compressed and generates an elastic force to drive the core rod 120 to move toward the second position.
[0064] like Figure 1As shown, this utility model provides a water outlet device, which can be a shower head or a faucet. The water outlet device includes a base, a water outlet assembly 200, and a pipe assembly 100 as described above. Specifically, the base is connected to a water source, the outer pipe 110 is connected to the base, and the inlet 115 of the outer pipe 110 is connected to the base. In some embodiments, the base and the outer pipe 110 are connected by a pull-out water pipe, which can be pulled out to adjust the position of the pipe assembly 100, making it more convenient to use. The water outlet assembly 200 is connected to the pipe assembly 100. Specifically, the outer pipe 110 is provided with a connecting part 116, which is plate-shaped. The connecting part 116 is connected to the water outlet assembly 200 by fasteners. A groove 117 is formed on the connecting part 116, and a water outlet window 113 is located on the bottom wall of the groove 117. The water outlet assembly 200 is connected to the water outlet window 113. The water outlet assembly 200 is provided with at least one water outlet hole 201. When the core rod 120 is in the first position, water is transported to the pipeline assembly 100 through the base. In the pipeline assembly 100, the water flows along the first water path and then flows to the water outlet assembly 200. Finally, it is provided to the user through the water outlet hole 201.
[0065] In summary, this utility model embodiment provides a pipeline assembly 100, which forms a first water channel or a second water channel within the pipeline assembly 100 by moving the core rod 120 between a first position and a second position to meet the user's water usage needs. By providing a transition structure 114 connected to both the first sidewall 1131 and the second sidewall 1132, during the movement of the seal from one side of the water outlet window 113 to the other side, a portion of the outer edge of the seal is separated from the water outlet window 113, avoiding or reducing friction between the second seal 126 and the edge of the water outlet window 113, thereby reducing the frictional force on the seal, extending the service life of the seal, and reducing the probability of failure of the pipeline assembly 100.
[0066] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit it. It should be pointed out that those skilled in the art can make several improvements and substitutions without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
