[0066] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the inventive aspects of the example implementations to those skilled in the art. Like reference numerals refer to like elements throughout the figures, and descriptions of the same elements will be omitted from descriptions of the same elements in different figures.

[0067] In the following description of various example embodiments of the present application, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration various example structures, systems, and steps in which aspects of the present application can be practiced. It is to be understood that other specific arrangements of parts, structures, example devices, systems, and steps can be utilized and that structural and functional modifications can be made without departing from the scope of the present application. Also, while the terms "over," "under," "between," and the like can be used in the present description for the purpose of explanation only, such terms can be used in the context of relative positioning in the example structures shown in the drawings. Nothing in this specification should be construed as requiring a specific three dimensional orientation of structures in order to fall within the scope of the present application.

[0068] It is to be understood that the terms "including", "comprising", "consisting" and "having" and any variations thereof used in the present application are intended to cover the instance in which one or more steps, components, features, structures, and / or elements are present, but do not exclude the presence of one or more other steps, components, features, structures, and / or elements. For example, a process, method, system, product, or apparatus that comprises a list of steps or units is not necessarily limited to the listed steps or units, but can optionally further comprise additional steps or units not listed, or can optionally further comprise other steps or units inherent to such process, method, system, product, or apparatus.

[0069] Relative terms such as "lower" or "bottom" and "upper" or "top" can be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the "lower" side of other elements would then be oriented on "upper" sides of the other elements. The exemplary term "lower" can therefore encompass both an orientation of "lower" and "upper," depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as "below" or "beneath" other elements would then be oriented "above" the other elements. The exemplary terms "below" or "beneath" can therefore encompass both an orientation of "below" and "above," depending on the particular orientation of the figure.

[0070] Referring to Figures 1 to 3 The present application provides a distributor 1 comprising a first section 10, a second section 20 and a third section 30. The first section 10 has a first cavity 101; the second section 20 has a second cavity 201; the third section 30 has a third cavity 301. Wherein the first section 10, the second section 20 and the third section 30 are all formed with connecting holes for connecting connecting pipes, the first section 10, the second section 20 and the third section 30 are connected into one body, the first cavity 101, the second cavity 201 and the third cavity 301 are communicated to form an inner cavity of the distributor 1, the cross-sectional area of the first cavity 101 is larger than that of the second cavity 201, and the cross-sectional area of the second cavity 201 is larger than that of the third cavity 301.

[0071] The distributor 1 of the present application is connected by a multi-section cavity structure, the cavities of the multi-section structure are communicated to form an inner cavity of the distributor 1 for distributing fluid, and the cross-sectional area of the first cavity 101 is larger than that of the second cavity 201, and the cross-sectional area of the second cavity 201 is larger than that of the third cavity 301, the inner cavity of the distributor 1 is designed in a variable size form, which can meet the needs of different flow rates of different outflow pipes.

[0072] Wherein, the cross section refers to the plane perpendicular to the axis direction of each section of the distributor 1.

[0073] In the embodiment, the first cavity 101, the second cavity 201 and the third cavity 301 are all cylindrical in shape, the diameter of the cross section of the first cavity 101 is D1, the diameter of the cross section of the second cavity 201 is D2, and the diameter of the cross section of the third cavity 301 is D3, and D1>D2>D3. The inner cavities of the distributor 1 are all designed to be cylindrical in shape, which is convenient for processing and can reduce fluid disturbance and turbulence during fluid flow distribution, maintain the stability and sustainability of fluid flow in the distributor 1, avoid dead zones of fluid in the inner cavities of the distributor 1, facilitate uniform fluid mixing, and improve distribution uniformity. The diameters of the fluid flow cavities gradually decrease, which can achieve more flow with a larger diameter and less flow with a smaller diameter, meet the flow requirements of the outlet pipes, and enhance the fluid distribution capacity of the distributor 1.

[0074] In the embodiment, the second section 20 connects the first section 10 and the third section 30. The second section 20 is located between the first section 10 and the third section 30, so that the cross-sectional area (in the embodiment, the diameter) of the inner cavities of the distributor 1 gradually decreases, which can improve the stability of fluid flow when the fluid is distributed through the distribution pipe and meet different requirements of the flow of the fluid flowing out of the second cavity 201 and the third cavity 301.

[0075] In the embodiment, the distributor 1 further includes a fourth section 40, the fourth section 40 is connected with the third section 30, the fourth section 40 has a fourth cavity 401, and the fourth section 40 is provided with a connecting hole for connecting the pipes. The fourth cavity 401 is in communication with the first cavity 101, the second cavity 201 and the third cavity 301. The distributor 1 further includes the fourth section 40, which can increase the number of pipes for distributing fluid, improve the capacity of the distributor 1 for distributing fluid, improve production efficiency, and reduce cost. The cross-sectional area of the fourth cavity 401 is smaller than that of the third cavity 301. The cavity of the fourth section 40 is smaller, which can also maintain the stability of fluid flow, and meet the requirements of small flow of the outlet pipes.

[0076] In the embodiment, the diameters of the connecting holes on the first section 10, the second section 20, the third section 30 and the fourth section 40 gradually decrease. In this way, the flow of each pipe connected with the connecting holes can be further controlled. The connecting holes all extend outward to form flanges.

[0077] In this embodiment, the fourth cavity 401 is cylindrical in shape, and the diameter of the cross-section of the fourth cavity 401 is D4, where D3 > D4. The cylindrical shape facilitates processing and reduces fluid disturbance and turbulence during the fluid flow distribution process, maintaining the stability and sustainability of the fluid flow within the distribution. This avoids dead zones in the fluid within the distributor 1, promoting uniform fluid mixing. In this embodiment, the first segment 10 includes a first connecting hole 102, the second segment 20 includes a second connecting hole 202, the third segment 30 includes a third connecting hole 302, and the fourth segment 40 includes a fourth connecting hole 402.

[0078] In this embodiment, the first segment 10 has a closed structure at one end of the dispenser 1, and an open structure at the other end connected to the second segment 20. The fourth segment 40 has a closed structure at one end of the dispenser 1, and an open structure at the other end connected to the third segment 30. Both ends of the second segment 20 and the third segment 30 are open structures.

The fourth segment 40 has a closed structure at one end of the dispenser 1, and an open structure at the other end connected to the third segment 30.

Therefore, in the following description of the present embodiment, mainly the differences from the distributor 1 of the first embodiment will be described. Among them, the distributor 1 of the third embodiment mainly selects the open structure with both ends open for the two end segments (the first segment 10 and the fourth segment 40) of the distributor 1, and sets end covers 50 at both ends of the distributor 1 to block the inner cavity of the distributor 1.

Figure 6 Figure 7 In the present embodiment, referring to Figs. 1 to 3, the end cover 50 includes a cover body 502 and a cover edge 501, the cover edge 501 connects the cover body 502 and forms a cover cavity 503 with the cover body 502, the cover cavity 503 communicates with the inner cavity of the distributor 1 when installed, and the cover edge 501 is fixed to the first segment 10 and the fourth segment 40, which can be fixed by welding or other detachable fixing methods such as threads, and when fixed by the detachable fixing method, a sealing structure needs to be provided at the position of the cover edge 501 that connects with the first segment 10 and the fourth segment 40, such as the inner side or the outer side.

[0083] The distributor 1 of the present application also has a fourth embodiment, which has substantially the same structure in basic configuration as the distributor 1 of the first embodiment. Figure 4 Therefore, in the following description of the distributor 1 of the fourth embodiment, the structures already described in the first embodiment will not be repeated. In addition, the same reference numerals are marked for the structures of the distributor 1 that are the same as those described in the first embodiment. Therefore, in the following description of the present embodiment, mainly the differences from the distributor 1 of the first embodiment will be described. Among them, the distributor 1 of the fourth embodiment mainly selects the open structure with both ends open for the two end segments of the distributor 1, and sets end covers 50 at both ends of the distributor 1 to block the inner cavity of the distributor 1. The structure of the end cover 50 and other contents are similar to those of the end cover 50 in the third embodiment of the distributor 1, and will not be described here. Figure 4 Figure 4 Figure 4

The end cover 50 of the present application can be directly blanked by stamping, or can be stretched after blanking and then planarized.

[0085] Referring to Figures 8 to 10 The present application also provides a distributor assembly 2, comprising a distributor 1 and a connector pipe, the connector pipe comprising a first connector pipe 11, a second connector pipe 21 and a third connector pipe 31, the first connector pipe 11 being connected to the first section 10 through the first connecting hole 102, the second connector pipe 21 being connected to the second section 20 through the second connecting hole 202, and the third connector pipe 31 being connected to the third section 30 through the third connecting hole 302. The distributor 1 is the distributor 1 of the embodiment of the present application. Figures 1 to 3

[0086] The distributor assembly 2 of the present application is connected by the distributor 1 with multiple sections of cavity structure, the cavities of the multiple sections are communicated to form the inner cavity of the distributor 1 for distributing fluid, the inner cavity of the distributor 1 is designed in the form of variable size to meet the needs of different flow rates of different outlet pipes, and each section of the distributor 1 is connected to different connector pipes to meet the diversified needs of fluid distribution.

[0087] In the present embodiment, the distributor 1 further comprises a fourth section 40 connected and communicated with the third section 30, and the connector pipe further comprises a fourth connector pipe 41 connected to the fourth section 40 through the fourth connecting hole 402.

[0088] In the present embodiment, the cross-sectional area of the pipe cavity of the first connector pipe 11 is greater than or equal to that of the second connector pipe 21, and the cross-sectional area of the pipe cavity of the second connector pipe 21 is greater than that of the third connector pipe 31. The cross-sectional areas of the pipe cavities of the connector pipes are different, so that the flow rates of the fluids passing through the connector pipes are different to meet the needs of the equipment connected by the connector pipes.

[0089] In the present embodiment, the inner diameter of the first connector pipe 11 is d1, the inner diameter of the second connector pipe 21 is d2, and the inner diameter of the third connector pipe 31 is d3, so that d1≥d2>d3. Such design can make the flow rate of the fluid passing through the connector pipe with large inner diameter large and the flow rate of the fluid passing through the connector pipe with small inner diameter small. d1≥d2>d3 can further enhance the flow rate control of the distributor 1 for distributing fluid and improve the use efficiency of the distributor 1, so that the distributor assembly 2 can play a greater role in the process of distributing fluid.

[0090] ​In the present embodiment, the third connecting pipe 31 includes a first sub-pipe 311 and a second sub-pipe 312, the first sub-pipe 311 connects the third section 30 through the first sub-hole 3021, the second sub-pipe 312 connects the third section 30 through the second sub-hole 3022, the inner diameter of the first sub-pipe 311 and the inner diameter of the second sub-pipe 312 are equal, and both are equal to the inner diameter of the third connecting pipe 31. The two sub-pipes with equal inner diameters connect the third section 30 of the distributor 1, which can allow the distributor assembly 2 to distribute fluid to more associated devices through more connecting pipes. The two sub-pipes with equal inner diameters are convenient to process, simple in structure, and can be connected to external devices with the same fluid flow demand.

[0091] In the present embodiment, the inner diameter of the first connecting pipe 11 is d1, the inner diameter of the second connecting pipe 21 is d2, the inner diameter of the third connecting pipe 31 is d3, and the inner diameter of the fourth connecting pipe 41 is d4, then d1≥d2>d3≥d4. d2>d3 can further enhance the flow control of the distributor assembly 2 in distributing fluid, so that the fluid flow in the connecting pipe with a larger inner diameter is more, and the fluid flow in the connecting pipe with a smaller inner diameter is less, which can meet the external devices with different flow demands. d1≥d2, or d3≥d4, can also enhance the flow control of the distributor assembly 2 in distributing fluid, and meet the external devices with different flow demands.
