Description

Technical Field

[0001] This utility model relates to the field of dispenser technology, and more specifically, to a dispenser and a dispenser assembly having the same. Background Technology

[0002] Currently, distributors are typically installed in pipeline systems to distribute the flow path of fluids. A distributor usually includes a housing, one end of which is connected to an inlet pipe, and the other end is provided with multiple connection holes. These connection holes are connected to multiple branch pipes. After the fluid enters the housing through the inlet pipe, it can enter the multiple branch pipes through the multiple connection holes to achieve fluid diversion.

[0003] In existing technologies, welding is typically used to connect the housing and the distributor pipe. To extend the welding fit length and improve the connection strength between the distributor pipe and the housing, a fitting flange is formed on the outer periphery of the connecting hole by drawing or stamping the housing. The distributor pipe is then welded to the fitting flange. However, due to the thickness of the housing, the length of the fitting flange is limited when the housing is drawn or stamped, thus limiting the welding fit length between the distributor pipe and the housing, which affects the connection strength between the distributor and the distributor pipe. Utility Model Content

[0004] This utility model provides a distributor and a distributor assembly having the same, which further improves the connection strength between the distributor and the shunt pipe on the existing basis.

[0005] According to one aspect of the present invention, a distributor is provided, comprising: a housing having a distribution cavity having an inlet end and an outlet end disposed opposite to each other, the outlet end having a plurality of connecting holes, the outer periphery of the connecting holes having a mating flange for inserting a diverter tube; an extension structure disposed within the distribution cavity near one end of the connecting holes, the extension structure including a insertion hole, the insertion hole being recessed inward from the end face of the extension structure, the insertion hole having a stepped surface for abutting against the diverter tube, the insertion hole and the connecting holes being aligned one-to-one; the mating flange extending outward or inward of the distribution cavity, when the mating flange extends inward of the distribution cavity, the mating flange is located within the insertion hole, and there is a gap between the free end of the mating flange and the stepped surface.

[0006] Furthermore, the dispenser also includes a limiting member disposed within the dispensing cavity, the limiting member having a insertion hole.

[0007] Furthermore, when the mating flange extends into the inner side of the distribution cavity, the mating flange insertion hole engages with the mating flange, and the end of the limiting member near the mating flange abuts against the inner wall of the distribution cavity.

[0008] Furthermore, the limiting component also has multiple diversion holes, and multiple insertion holes are arranged one-to-one with the multiple diversion holes. The insertion holes and diversion holes are interconnected. The inner diameter of the insertion hole is larger than the inner diameter of the diversion hole. A stepped surface is formed between the inner diameter of the insertion hole and the diversion hole. The stepped surface is used to limit the displacement of the diversion pipe into the distribution cavity.

[0009] Furthermore, the length of the weld formed by the flange and the gap fit is greater than or equal to 3mm.

[0010] Furthermore, when the mating flange extends into the inner side of the distribution cavity, a welding groove is provided at the port of the connecting hole on the side away from the distribution cavity, and the welding groove is used to place the welding ring.

[0011] Furthermore, the limiting member has a flow guide boss on the side opposite to the connecting hole, and multiple flow diversion holes surround the outer periphery of the flow guide boss. The diameter of the flow guide boss gradually increases from the inlet end to the outlet end.

[0012] Furthermore, the guide boss has a conical structure, and the cone angle of the guide boss is α, where 45°≤α≤135°.

[0013] Furthermore, in the axial direction of the housing, the projection of the flow divider hole at least partially coincides with the projection of the flow guide boss, and the flow divider hole penetrates the flow guide boss.

[0014] Furthermore, in the axial direction of the housing, the projection of the limiting member has a first reference circle and a second reference circle, the projection of the guide boss forms the first reference circle, the second reference circle passes through the center of multiple diversion holes, and the first reference circle and the second reference circle coincide.

[0015] According to another aspect of the present invention, a distributor assembly is provided, the distributor assembly including a distributor and a diverter tube, the distributor being the aforementioned distributor, and the diverter tube being welded to the housing of the distributor by means of a mating flange and an extension structure.

[0016] Applying the technical solution of this application, the distributor includes a housing and an extension structure. The inlet end of the housing is used to connect to an inlet pipe. Fluid enters the distribution chamber through the inlet pipe and flows to multiple distribution holes through the distribution chamber, so that the fluid enters the distribution pipe to achieve fluid distribution. When assembling the distribution pipe and the housing, the distribution pipe can be welded to the housing through a mating flange. During the welding connection, solder can flow into the space between the distribution pipe and the mating flange to form a weld, achieving a welded connection between the housing and the distribution pipe. When the mating flange extends outward from the distribution chamber, i.e., when the housing is pulled outward from the distribution chamber to form the mating flange, the distribution pipe can continue to extend into the insertion hole, and the solder melts and enters the space between the insertion hole and the distribution pipe. When the mating flange extends inward from the distribution chamber, i.e., when the housing is pulled inward from the distribution chamber to form the mating flange, the distribution pipe can continue to extend into the insertion hole, and the solder melts and enters the gap, extending the weld length and further improving the welding strength between the distribution pipe and the housing. By setting an extension structure, damage that may occur due to the increased length of the mating flange during the processing of the housing can be prevented without increasing the length of the mating flange. This extends the flow path of the solder, improves the welding effect, ensures the connection strength between the distributor pipe and the housing, and reduces the risk of leakage from the distributor.

[0030] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] like Figures 1 to 3 As shown, this embodiment of the utility model provides a distributor, which includes a housing 100 and an extension structure. The housing 100 has a distribution cavity 110, which has an inlet end 111 and an outlet end 112 disposed opposite to each other. The outlet end 112 is provided with a plurality of connection holes 120, and the outer periphery of the connection holes 120 is provided with a mating flange 130 for inserting a diverter tube 01. The extension structure is disposed within the distribution cavity 110 near one end of the connection holes 120. The extension structure includes a insertion hole 220, which is recessed inward from the end face of the extension structure. The insertion hole 220 has a stepped surface 230 for abutting against the diverter tube 01. The insertion hole 220 and the connection holes 120 are aligned one-to-one. The mating flange 130 extends outward or inward to the distribution cavity 110. When the mating flange 130 extends inward to the distribution cavity 110, the mating flange 130 is located inside the insertion hole 220, and there is a gap 300 between the free end of the mating flange 130 and the stepped surface 230.

[0032] Applying the technical solution of this application, the distributor includes a housing 100 and an extension structure. The inlet end 111 of the housing 100 is used to connect to the inlet pipe. Fluid enters the distribution chamber 110 through the inlet pipe and flows through the distribution chamber 110 to multiple diversion holes 210, so that the fluid enters the diversion pipe 01 to achieve fluid distribution. When assembling the diversion pipe 01 and the housing 100, the diversion pipe 01 can be welded to the housing 100 through the mating flange 130. During the welding connection, solder can flow into the space between the diversion pipe 01 and the mating flange 130 to form a weld, thus achieving the welding connection between the housing 100 and the diversion pipe 01. When the mating flange 130 extends outward from the distribution chamber 110, that is, when the housing 100 is pulled outward from the distribution chamber 110 to form the mating flange 130, the diversion pipe 01 can continue to extend into the insertion hole 220, and the solder melts and enters the space between the insertion hole 220 and the diversion pipe 01; when the mating flange 130 extends inward from the distribution chamber 110... When the housing 100 is pulled inwards towards the distribution cavity 110 to form the mating flange 130, the distributor tube 01 can continue to extend into the insertion hole 220. The gap 300 will create a capillary effect on the molten solder, causing it to flow towards and enter the gap 300. The solder within the gap 300 can then form a welded connection with the outer wall of the distributor tube 01, thereby extending the weld length and further improving the weld strength between the distributor tube 01 and the housing 100. By setting the extension structure, damage that may occur due to increasing the length of the mating flange 130 during its processing can be prevented without increasing the length of the housing 100. This extends the flow path of the solder, improves the welding effect, ensures the connection strength between the distributor tube 01 and the housing 100, and reduces the risk of leakage in the distributor.

[0033] Specifically, the dispenser also includes a limiting member 200, which is disposed within the dispensing cavity 110, such as... Figure 4 and Figure 5 The insertion holes 220 shown are formed on the limiting member 200, and multiple insertion holes 220 are arranged one-to-one with multiple mating flanges 130. With this arrangement, the gap 300 between the stepped surface 230 and the diversion tube 01 can provide flow space for the solder. The solder entering the gap 300 can fix the limiting member 200 and the diversion tube 01, extend the welding area, and improve the connection strength between the diversion tube 01 and the housing 100.

[0034] Furthermore, when the mating flange 130 extends into the distribution cavity 110, the mating flange 130 can be inserted into the insertion hole 220, and the end of the limiting member near the mating flange 130 abuts against the inner wall of the distribution cavity 110. In this way, the housing 100 and the mating flange 130 can be inserted into the insertion hole 220, providing a positioning basis for the limiting member 200, ensuring that the insertion hole 220 can be aligned with the diverter pipe 01, thereby ensuring the accuracy of the assembly of the limiting member 200.

[0035] In this application, the limiting member 200 also has multiple diversion holes 210, and multiple insertion holes 220 are arranged one-to-one with the multiple diversion holes 210. The insertion holes 220 and the diversion holes 210 are interconnected. The inner diameter of the insertion hole 220 is larger than the inner diameter of the diversion hole 210. A stepped surface 230 is formed between the inner diameter of the insertion hole 220 and the diversion hole 210. The stepped surface 230 is used to limit the displacement of the diversion pipe 01 into the distribution cavity 110. With this arrangement, the stepped surface 230 can limit the distance of the diversion pipe into the distribution cavity 110. When the diversion pipe passes through the connecting hole 120 and moves to abut against the stepped surface 230, it can be determined that the diversion pipe is installed in place, thus achieving the positioning of the diversion pipe. At the same time, the stepped surface 230 can also limit the continued flow of solder, ensuring that the solder in the gap 300 does not flow excessively, thereby ensuring that a sufficient amount of solder can be maintained at the gap 300 to ensure the welding strength.

[0036] Specifically, the weld length formed by the flange 130 and the gap 300 is greater than or equal to 3mm. When this distance is less than 3mm, the welding area between the distributor pipe and the housing 100 is too small, the connection strength is poor, it cannot effectively fix the distributor pipe and the housing 100, and it will increase the risk of fluid leakage in the distribution cavity 110. This application ensures the welding strength of the distributor pipe and reduces the risk of internal leakage in the distribution cavity 110 by setting the distance between the port of the connecting hole 120 on the side away from the limiting member 200 and the stepped surface 230 to be greater than or equal to 3mm. Specifically, the distance between the port of the connecting hole 120 on the side away from the limiting member 200 and the stepped surface 230 can be set to 3mm, 4mm, or 5mm.

[0037] Reference Figure 3 As shown, when the mating flange 130 extends into the inner side of the distribution cavity 110, a welding groove 121 is provided at the port of the connecting hole 120 on the side away from the distribution cavity 110. The welding groove 121 is used to place the welding ring for welding work between the diverter pipe and the housing 100.

[0038] like Figure 6 and Figure 7As shown, the limiting member 200 has a flow guide boss 240 on the side opposite to the connecting hole 120. Multiple flow dividers 210 surround the outer periphery of the flow guide boss 240, and the diameter of the flow guide boss 240 gradually increases from the inlet end 111 to the outlet end 112. When the fluid flows unevenly and impacts the limiting member 200, it will generate significant noise in the distribution chamber 110 and cause uneven flow rates of the fluid entering the multiple flow dividers. By setting the flow guide boss 240, when the fluid flows through the flow guide boss 240 and out through the flow dividers 210, the fluid will first impact the flow guide boss 240 and then flow to the flow dividers 210 after being guided by the flow guide boss 240. The flow guide boss 240 helps to distribute the fluid evenly and reduces the noise of the fluid. Moreover, when the fluid is multiphase or mixed with multiple fluids, the impact of the fluid on the flow guide boss also helps to mix the fluid evenly and improves the distribution effect of the distributor.

[0039] In a preferred embodiment of this application, the guide boss 240 has a conical structure. This design reduces the resistance of the fluid passing through the guide boss 240, ensuring effective fluid flow. Figure 5 As shown, the cone angle of the guide boss 240 is α, where 45°≤α≤135°. When α<45°, the cone angle is too small; when α>135°, the cone angle is too large. Neither can effectively guide the fluid and ensure thorough mixing, thus reducing the guiding effect of the guide boss 240. By setting 45°≤α≤135°, the guiding and mixing effect of the guide boss 240 on the fluid can be guaranteed, allowing the fluid to flow more stably and reducing fluid flow noise. Specifically, α can be set to 45°, 90°, or 135°.

[0040] Furthermore, in the axial direction of the housing 100, the projection of the diversion hole 210 at least partially coincides with the projection of the guide boss 240, and the diversion hole 210 penetrates the guide boss 240. With this configuration, the fluid guided by the guide boss 240 can directly enter the diversion hole 210 and exit the distribution chamber 110, making the fluid flow path smoother, reducing the turning points in the fluid flow path, thereby reducing the flow resistance of the fluid in the distribution chamber 110 and ensuring the fluid flow efficiency.

[0041] Reference Figure 6As shown, along the axial direction of the housing 100, the projection of the limiting member 200 has a first reference circle and a second reference circle. The projection of the guide boss 240 forms the first reference circle, and the second reference circle passes through the center of the multiple diversion holes 210. The first reference circle and the second reference circle coincide, meaning that the center of the multiple diversion holes 210 is on the projection circle of the end face of the guide boss 240 near the limiting member 200. This arrangement allows some fluid to be guided through the guide boss 240, while some fluid directly enters the diversion holes 210. This reduces turbulence caused by fluid that fails to directly enter the diversion holes 210 flowing back to them due to the structural deflection of the housing 100. This ensures more reliable fluid diversion when entering the diversion holes 210, improves the diversion effect of the guide boss 240, and reduces noise generated by fluid flow.

[0042] In this application, the outlet end 112 has an end plate, the connection hole 120 is disposed on the end plate, the inner wall of the housing 100 has a limiting protrusion 140, and the limiting member 200 is disposed between the end plate and the limiting protrusion 140. With this arrangement, the displacement of the limiting member 200 can be restricted axially by the end plate and the limiting protrusion 140, ensuring the stability of the limiting member 200 installed in the distribution cavity 110, thereby improving the limiting effect of the limiting member 200 on the diversion pipe.

[0043] In some feasible embodiments of this application, the limiting protrusion 140 can be a dot-shaped protrusion formed by stamping inward on the housing 100, and the limiting member 200 is limited by stamping out multiple dot-shaped limiting protrusions 140.

[0044] In some other embodiments of this application, the limiting protrusion 140 may be an annular protrusion formed by inward spinning of the housing 100 to limit the limiting member 200.

[0045] According to another aspect of this application, a distributor assembly is also provided, comprising a distributor and a diverter pipe 01. The distributor is the one described above, and the diverter pipe 01 is welded to the housing 100 of the distributor via a mating flange 130 and an extension structure. This arrangement prevents the diverter pipe 01 from separating from the distributor or causing welding instability, ensures that there is no leakage at the connection between the diverter pipe 01 and the distributor, guarantees the connection strength between the diverter pipe 01 and the distributor, and improves the overall sealing performance and structural strength of the distributor assembly.
