DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that when a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed to the other component or there may be a central component at the same time.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0039] When different reagents need to be packaged for use, it is very inconvenient to use different packaging equipment. However, when switching between the same packaging equipment, cross-contamination is likely to occur between the pipelines, making it difficult to keep them clean. In addition, contamination is likely to occur at the access valve port each time different reagents are switched. The overall packaging safety, efficiency, and convenience are all low.

[0040] Based on this, the present application provides an in-situ cleaning and dispensing system 100, which can clean the dispensing system structure in-situ, and switch different materials in-situ for feeding and dispensing. It should be noted that cleaning includes but is not limited to one or more of washing, sterilization, emptying, and drying. Furthermore, the in-situ cleaning and dispensing system 100 provided by the present application is used in the field of material dispensing, including but not limited to the dispensing of materials such as biological reagents, chemical reagents, food and beverages.

[0041] See also Figures 1 to 5 The in-situ cleaning and dispensing system 100 provided in the present application includes a feeding device group 10, a cleaning pipeline group 20, a cleaning multi-way valve group 70, a feeding pipeline group 30, a feeding multi-way valve 40 and a dispensing device 60;

[0042] The feeding device group 10 includes a plurality of feeding devices 1001, each of which includes a feeding source 15 and a reversing valve 11. The feeding source 15 of at least one feeding device 1001 is gas, the feeding source 15 of at least one feeding device 1001 is cleaning liquid, and the feeding source 15 of at least one feeding device 1001 is a material to be packaged; the reversing valve 11 has at least three valve ports, which are respectively defined as an inner valve port 111, a cleaning valve port 112, and a reversing valve port 113. and a feed valve port; wherein the inner valve port 111 is connected to the feed source 15, the cleaning valve port 112 is connected to one of the valve ports of the cleaning multi-way valve group 70 through a cleaning pipeline 21 in the cleaning pipeline group 20; the feed valve port is connected to one of the feed inlets 41 of the feed multi-way valve 40 through a feed pipeline 31 in the feed pipeline group 30; the material distribution device 60 is driven and connected to the feed outlet 42 of the feed multi-way valve 40 to provide a driving force for pumping out the feed source;

[0043] The cleaning multi-way valve group 70, the material feeding multi-way valve 40, and each reversing valve 11 can cooperate with each other to switch the provided material supply source 15 and the flow path of the material supply source 15 to complete in-situ cleaning, in-situ feeding, and in-situ material distribution.

[0044] The in-situ cleaning dispensing system 100 provided in the present application can use cleaning liquid to perform in-situ cleaning of any flow path and valve port through the coordination between pipelines and valves, and use gas to complete the emptying and drying of residual liquid, so that each flow path in the dispensing system remains clean, and cross-contamination problems after material storage, material access and material switching are effectively avoided, so that different materials to be packaged can be quickly switched and packaged in the same packaging pipeline system, thereby greatly improving the packaging efficiency, packaging convenience and packaging safety.

[0045] See also Figure 1 and Figure 4 In one embodiment, the reversing valve 11 is a three-way valve, that is, a three-position three-way valve. It is understood that in other embodiments, the reversing valve 11 may also be a four-way valve or other types of valve bodies, as long as the function of the in-situ cleaning and dispensing system 100 is not affected.

[0046] See also Figure 1 and Figure 4 In one embodiment, the cleaning multi-way valve group 70 includes a plurality of T-type three-way valves 71 arranged in series, and two valve ports of the plurality of T-type three-way valves 71 are connected in parallel and opposite to each other in sequence to form a main bypass channel 701, and the other valve ports of the plurality of T-type three-way valves 71 correspond to form a plurality of branch bypass channels 702. In other words, a plurality of branch bypass channels 702 are connected in parallel and aggregated to a main bypass channel 701, and each branch bypass channel 702 can be switched on and off with the aggregated main bypass channel 701. The pipeline flow channel configuration equivalent to the cleaning multi-way valve group 70 is composed of a plurality of T-type structure pipelines and a plurality of multi-way valves in parallel, and a separate valve is provided at each inlet and outlet to control the on and off of the main bypass channel 701 and the branch bypass channel 702. It can be understood that adjacent T-type three-way valves 71 are connected by connecting pipes.

[0047] Since the cleaning multi-way valve group 70 is an intermediate valve station connected to the cleaning pipeline 21 of each feeding device 1001 in the whole system, it is equivalent to a collection device for switching cleaning liquid and clean air. At the same time, during the initialization process of the in-situ cleaning and material distribution system, it is also necessary to use cleaning liquid to clean and sterilize the cleaning multi-way valve group 70. Therefore, it is necessary to clean the flow channel in the multi-way valve group 70 with a flow direction design so that there are no blind ends and cleaning dead corners when the cleaning liquid passes through. At the same time, after the cleaning is completed, a flow direction design is also required to ensure that the clean air can drain the cleaning liquid in the valve group of the cleaning pipeline 21, and there is also no blind end and dead corner. Therefore, when the cleaning multi-way valve group 70 is composed of multiple T-type three-way valves 71 connected in parallel, it is necessary to require the two ends of the cleaning multi-way valve group 70 in the horizontal direction, one end is used for the access of cleaning liquid (for example, ethanol), and the other end is used for the access of gas (for example, clean air), so that the cleaning liquid or gas can pass through all valve bodies, and blind ends and dead corners are not easy to appear.

[0048] Therefore, in one embodiment, a feed source 15 is configured as a feed device 1001 for gas and a feed source 15 is configured as a feed device 1001 for cleaning liquid, respectively, through the cleaning pipelines 21 connected to each other, and are horizontally connected from both sides to the two valve ports at both ends of the main bypass channel 701. In other words, when the cleaning multi-way valve group 70 is in the form of multiple parallel T-shaped structures, the T-shaped structures are required to be arranged in a positive direction, so that at least one cleaning liquid is horizontally connected from one end, at least one gas is horizontally connected from the other end, and all the materials to be distributed are connected from the lower end of the T-shaped structure, and the cleaning liquid and gas can flow through the entire main bypass channel 701 and both sides of the main bypass channel 701, and can also flow out from each branch bypass channel 702 through the main bypass channel 701, effectively avoiding the occurrence of cleaning dead corners and blind ends.

[0049] It is understood that in other embodiments, the cleaning multi-way valve group 70 may also be composed of other forms of parallel and / or series pipelines and different valves. For example, in one embodiment, the cleaning multi-way valve group 70 is composed of a multi-inlet single-outlet multi-way switching valve and a single-inlet multi-outlet multi-way switching valve in series. In this case, there is no restriction on the access position of the feeding device 1001 configured as a gas and the feeding device 1001 configured as a cleaning liquid.

[0050] See also Figure 1 and Figure 4 In one embodiment, the feed source 15 is configured as a gas feed device 1001, and further includes a one-way valve 12 and a filter 13. The feed source 15 is configured as a gas feed device 1001, and the reversing valve 11 of the gas feed device 1001 is an inverted T-type three-way valve, wherein the inner valve port 111 faces upward and is sequentially connected to the one-way valve 12, the filter 13 and the feed source 15. That is, the installation position relationship of the three-way valve, the one-way valve 12 and the filter 13 of the gas feed device 1001 requires that the filter 13 is on the one-way valve 12, the one-way valve 12 is on the three-way valve, and the three are installed vertically in series, and the three-way valve is installed in an inverted T shape.

[0051] With such an arrangement, the inverted T-type three-way valve can ensure that when the system is connected to the air intake device 102 for air supply, the cleaning liquid can also clean the inside of the three-way valve of the corresponding air supply feeding device 1001 through the cleaning pipeline, while ensuring that when the one-way valve 12 is switched to open the air intake, the cleaning liquid will not flow back into the air supply device 1001 for air supply.

[0052] In one embodiment, the feeding device 1001 in which the feeding source 15 is configured as gas further includes a storage container, which is connected to the side of the filter 13 away from the reversing valve 11 and is used to store the feeding source 15 configured as gas. In some embodiments, the gas may be clean air, and the air may not need to be stored in a storage container, but may be directly filtered through the filter 13 to become clean air and pass into the in-situ cleaning dispensing system 100. When the gas is nitrogen, helium, high-temperature steam or other gases, a storage container may be used for storage, so as to facilitate access and sterilization and cleaning.

[0053] See also Figure 1 and Figure 4 In one embodiment, the feeding device 1001 in which the feed source 15 is configured as a cleaning liquid or a material to be packaged further includes a storage container 14 and a filter 13. The storage container 14 is provided with a first hole and a second hole, wherein the first hole is connected to the inner valve port 111 of the reversing valve 11, and the second hole is connected to the filter 13. That is, when the feed source 15 is a liquid, a storage container 14 may be provided to store the feed source 15, and a hole for air intake is required to be provided so that the feed source 15 can be pumped out of the storage container 14 for packaging or use. The filter 13 is provided at the second hole to prevent the feed source 15 in the storage container 14 from being contaminated by the external environment.

[0054] Furthermore, when the cleaning liquid or the material to be packaged is volatile, the feed source is easily lost due to volatilization or pollutes the external environment after volatilization. Therefore, in some embodiments, the feed source 15 is configured as a feed device 1001 for the cleaning liquid or the material to be packaged, and further includes a one-way valve 12, and the second hole can be connected to the filter through the one-way valve 12 to reduce or avoid the risk of liquid loss or environmental pollution.

[0055] In one embodiment, the storage container 14 includes a receiving portion 141 and a blocking portion 142 connected to each other, and the first hole and the second hole are provided in the blocking portion 142; wherein the blocking portion 142, the one-way valve 12, the reversing valve 11 and the filter 13 are an integrated structure. It can be understood that the integrated structure is convenient for use, and is convenient for overall sterilization and cleaning.

[0056] It is understood that the gas includes but is not limited to one or more of air, nitrogen, helium, and high-temperature steam. The cleaning liquid includes but is not limited to one or more of bleach, acid and alkali solution, organic solvent, alcohol, water, and high-temperature steam.

[0057] It is understood that the use of a cleaning liquid with a bactericidal effect can simultaneously complete the cleaning and sterilization of the pipeline. The use of a volatile, residue-free cleaning liquid can facilitate rapid drying after cleaning. For example, the use of ethanol as a cleaning liquid can take into account the advantages of both sterilization and easy drying after cleaning.

[0058] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 In one embodiment, the material feeding multi-way valve 40 is a multi-inlet and single-outlet multi-way switching valve. Specifically, the material feeding multi-way valve 40 includes a main body 44 and a valve core 43 movably connected to the main body 44. The main body 44 is provided with a plurality of material feeding branches 45 and a material feeding main path 46. By rotating the valve core 43, different material feeding branches 45 can be switched to be connected to the material feeding main path 46.

[0059] It can be understood that the end of each feed branch 45 away from the valve core 43 is the feed inlet 41 of the feed multi-way valve 40, and the end of the feed main line 46 away from the valve core 43 is the feed outlet 42 of the feed multi-way valve 40. The feed sources 15 of multiple feeding devices 1001 enter the feed multi-way valve 40 from different feed branches 45 respectively, and share the same feed main line 46 to output to the outside of the feed multi-way valve 40. Therefore, when switching the material to be packaged, at least the path from the output main line to the end of the feed distribution equipment 60 needs to be cleaned.

[0060] See also Figure 3 It can be understood that in other embodiments, the material delivery multi-way valve 40 can also be a multi-input and multi-output multi-way switching valve. That is, in other embodiments, the material delivery multi-way valve 40 can have multiple material delivery outlets 42. In this way, each material delivery outlet 42 can be connected to a material distribution device 60 to increase the number of portions of the material to be distributed each time according to demand.

[0061] It can be understood that in some embodiments, the reversing valve and the cleaning multi-way valve group can also be implemented as Figure 2 and Figure 3 In other words, as long as the functions of in-situ cleaning, in-situ feeding and in-situ dispensing of the in-situ cleaning and dispensing system can be realized, in other embodiments, the types and configurations of the reversing valve, the cleaning multi-way valve group and the feeding multi-way valve are not limited.

[0062] See also Figure 1 , Figure 4 and Figure 5 Furthermore, the in-situ cleaning material distribution system 100 further includes a liquid distribution multi-way head 50, and the material distribution device 60 is connected to a material delivery outlet 42 of the material delivery multi-way valve 40 through the liquid distribution multi-way head 50. The liquid distribution multi-way head 50 facilitates the uniform distribution of the material to be distributed flowing to the material delivery multi-way valve 40 to the material distribution device 60.

[0063] See also Figure 1 , Figure 4 and Figure 5The liquid-distributing multi-way head 50 includes a main flow channel 52 and a plurality of branch flow channels 51 connected to the same end of the main flow channel 52; one end of the main flow channel 52 away from the branch flow channel 51 is connected to the material delivery outlet 42 of the material delivery multi-way valve 40; the other ends of the plurality of branch flow channels 51 are respectively connected to a plurality of liquid dispensing inlets 601 of the material distributing device 60; wherein the plurality of branch flow channels 51 are symmetrically arranged along the central axis of the main flow channel 52 in an annular direction, and the central axis of each branch flow channel 51 has an angle with the central axis of the main flow channel 52, and the angle is a right angle or an acute angle. With such an arrangement, each branch flow channel 51 has equal resistance, which is convenient for even and stable material distribution.

[0064] Furthermore, the central axes of the multiple branch flow channels 51 intersect at the same point on the central axis of the main flow channel 52; and / or, the flow channel shapes of the multiple branch flow channels 51 are the same; and / or, the inner wall finish of the multiple branch flow channels 51 is the same; and / or, the flow channel lengths of the multiple branch flow channels 51 are equal; and / or, the inner diameters of the multiple branch flow channels 51 are equal. In this way, it is possible to further ensure that the resistance, flow velocity, and flow rate of each flow channel are equal, and further reduce the risk of uneven flow rate in each branch flow channel 51. In addition, the smooth inner wall of the flow channel and the smooth structural transition can further avoid the occurrence of cleaning dead corners.

[0065] See also Figure 5 Furthermore, along the gravity direction, the liquid-separating multi-way head 50 is installed above the material-feeding multi-way valve 40. In other words, the main flow channel 52 of the liquid-separating multi-way head 50 is at the bottom, and the branch flow channels 51 are evenly distributed and obliquely upward, and the flow direction of the liquid in the liquid-separating multi-way head 50 is upward or obliquely upward. In this way, the inlet is located in the middle of the bottom, and the design of the branches being symmetrical and evenly distributed obliquely upward can facilitate the smooth discharge of gas bubbles in the flow channel, avoid the accumulation of bubbles to form air chambers, and further avoid the formation of air chambers to cause uneven flow.

[0066] See also Figure 5 Further, in this embodiment, the feed inlet 41 and the feed outlet 42 of the feed multi-way valve 40 are both facing upward. In this way, it is convenient to discharge the bubbles in the feed multi-way valve 40 and to connect the pipeline with the feed inlet 41.

[0067] Exemplarily, the degree of the angle is defined as a, 20°≤a≤60°. In this way, the fluid flow is more convenient and the air bubbles in the flow channel are discharged.

[0068] See also Figure 4 and Figure 5In one embodiment, each branch flow channel 51 includes a converging section 511 and a joint section 512 which are coaxially arranged and connected to each other. The end of the converging section 511 away from the joint section 512 is connected to the main flow channel 52. The joint section 512 is used to connect to the material distribution device 60. The inner diameter of the joint section 512 is larger than the inner diameter of the converging section 511, so as to form a sealing end surface 513 at the junction of the joint section 512 and the converging section 511. The sealing end surface 513 is used to achieve a sealed connection with the material distribution device 60.

[0074] Furthermore, the lower support shell 81 includes a plurality of panels, which are spliced ​​by buckling up and down, and buckling in front and back. This can prevent the risk of external liquid entering the shell and causing malfunction. In addition, the cable interface of the material distribution device 60 adopts a waterproof or shielding design to prevent the risk of being splashed by liquid in a laboratory environment.

[0075] See also Figure 4 and Figure 5 It should be noted that at least the material delivery inlet 41 of the material delivery multi-way valve 40 needs to be located in the upper protective shell 82, so as to facilitate the observation of the connection of the pipeline and the flow of the fluid in the pipeline.

[0076] The upper protective shell 82 includes an annular baffle 821 and a cover body 822 . The cover body 822 is disposed on the top of the annular baffle 821 and circumferentially blocks a portion of the side wall of the annular baffle 821 .

[0077] See also Figure 4 and Figure 5 In one embodiment, the in-situ cleaning and distributing device further includes at least one pipeline organizing member 91, which is installed on the housing 80, and at least one side of the pipeline organizing member 91 has a plurality of accommodating positions 911 for accommodating the pipe body. In this way, the cleaning pipeline, the material delivery pipeline 31 and the distributing pipeline can be fixed by the pipeline organizing member 91. The pipeline organizing member 91 can support and organize the pipeline, enhance the stability of the pipeline installation, and facilitate clearer distinction and observation of the status of each pipeline.

[0078] See also Figure 4 and Figure 5 In one embodiment, the pipeline arrangement member 91 is detachably mounted on the housing 80. Thus, after the pipeline arrangement member 91 is removed from the housing 80, it is easier to operate and arrange or remove the pipelines to be arranged.

[0079] In one embodiment, at least one side of the pipeline organizer 91 is provided with a mounting slot, and the pipeline organizer 91 is mounted on the top edge of the annular baffle 821 through the mounting slot and is located between the cover 822 and the annular baffle 821. In this way, it is convenient to centrally observe the connection status of each pipeline and the flow status of the fluid in each pipeline.

[0080] It is understood that in other embodiments, the pipe arrangement member 91 can also be fixed to the housing 80 in other ways. For example, a mounting protrusion is provided on at least one side of the pipe arrangement member 91, and a snap-fit ​​hole is provided on the protective shell, and the pipe arrangement member 91 is mounted on the protective shell through the snap-fitting of the mounting protrusion and the snap-fit ​​hole. It is understood that in other embodiments, the pipe arrangement member 91 can also be bonded to the housing 80.

[0089] See also Figure 1 , Figure 4 and Figure 5 In one embodiment, the in-situ cleaning dispensing system 100 also includes a collecting device 95, which includes a storage element 951 and a collecting tube 952.

[0096] See also Figure 1By way of example, the specific structure of the in-situ cleaning and dispensing system 100 in one embodiment is specifically described by taking the feeding device group 10 provided with 10 feeding devices 1001 as an example.

[0097] See also Figure 1 For ease of understanding, the feeding device 1001 whose feeding source 15 is gas is defined as the air inlet device 102, the feeding device 1001 whose feeding source 15 is cleaning liquid is defined as the liquid inlet device 101, and the other feeding devices 1001 whose feeding sources 15 are materials to be packaged are all defined as the feeding devices 103. The air inlet device 102 is numbered ⑩, the liquid inlet device 101 is numbered ⑨, and the other 8 feeding devices 1001 are numbered ①-⑧ respectively.

[0098] The cleaning multi-way valve group 70 includes 8 T-type three-way valves 71 arranged in a forward direction and connected in sequence. The 8 lower valve ports of the 8 T-type three-way valves 71 form 8 branch bypass channels 702, and are respectively connected to the cleaning valve ports 112 of the 8 feeding devices 1001 through 8 cleaning pipelines 21. The parallel valve ports of the 8 T-type three-way valves 71 are connected in sequence to form the main bypass channel 701, and the valve ports of the two T-type three-way valves 71 on both sides that are away from each other are respectively connected to the cleaning valve ports 112 of the liquid inlet device 101 and the cleaning valve ports 112 of the air inlet device 102 through two cleaning pipelines 21. Figure 1 , the eight T-type three-way valves 71 of the cleaning multi-way valve group 70 are numbered V1-V8 respectively. Among them, along the main bypass channel 701, the valve port of V8 away from V1 is connected to the cleaning valve port 112 of the liquid inlet device 101⑨ through the cleaning pipeline 21, the valve port of V1 away from V8 is connected to the cleaning valve port 112 of the air inlet device 102⑩ through the cleaning pipeline 21, and the lower valve ports of V1 to V8 are respectively connected to the cleaning valve ports of the feeding device 103①-103⑧ in sequence through a cleaning pipeline.

[0099] Furthermore, the feed multi-way valve 40 of the in-situ cleaning feed dispensing system 100 includes 10 feed inlets 41 and 1 feed outlet 42. The feed valve ports of 10 feeding devices 1001 are respectively connected to the 10 feed inlets 41 through 10 feed pipelines 31; the feed outlet 42 is connected to the feed dispensing equipment 60 through a liquid dispensing multi-way head 50, wherein the liquid dispensing multi-way head 50 has 1 main flow channel 52 and 8 branch flow channels 51, that is, 1 liquid dispensing inlet and 8 liquid dispensing outlets, the liquid dispensing inlet is connected to the feed outlet 42, the 8 liquid dispensing outlets are respectively connected to the 8 material dispensing liquid inlets of the feed dispensing equipment 60 through 8 liquid dispensing pipelines 61, and the 8 material dispensing liquid outlets of the feed dispensing equipment 60 are respectively connected to the 8 liquid dispensing nozzles 90 through 8 liquid dispensing pipelines 61.

[0100] See also Figure 1Furthermore, the distributing device 60 is provided with a second liquid contacting part 94, the input port of the collecting pipe 952 of the collecting device 95 is connected to the second liquid contacting part 94, and the anti-return structure 953 is configured as a one-way valve 12 arranged between the input port and the output port of the collecting pipe 952.

[0101] Furthermore, the cleaning liquid in the liquid inlet device 101⑨ is configured as ethanol, and the gas in the air inlet device 102⑩ is configured as air. It should be noted that the air entering the in-situ cleaning dispensing system 100 is clean air, which can be clean air directly introduced, or it can be clean air formed by filtering natural air through the filter 13 of the air inlet device 102. The materials to be packaged in the feeding devices 103①-⑧ are different biological reagents. In the present embodiment, the cleaning liquid is specifically a 75% ethanol solution. It will be understood that in other embodiments, the concentration of ethanol is not limited.

[0102] It should be noted that before the in-situ cleaning dispensing device is used for dispensing, initialization treatment needs to be completed to avoid contamination of the biological reagents to be packaged. Initialization treatment refers to using the ethanol in the liquid inlet device 101⑨ to clean and sterilize the flow path and valve body to which the fluid can flow in the entire in-situ cleaning dispensing system 100, and using the clean gas in the air inlet device 102 to empty and dry the residual ethanol in the flow path and valve body after cleaning and sterilization. After the initialization is completed, the flow path required for the dispensing of the target biological reagent can be connected by cooperating with the cleaning multi-way valve group 70, the material delivery multi-way valve 40 and each reversing valve 11, and the liquid dispensing pump of the dispensing device 60 is started in the positive direction to dispense once or multiple times as required.

[0103] It should be noted that when the next target biological reagent to be packaged is different from the last biological reagent that has been packaged, the flow path from the feeding multi-way valve 40 to the end of the dispensing device 60 needs to be cleaned and sterilized by ethanol and clean air and emptied and dried. It can be understood that the cleaning and sterilization process and the emptying and drying process can be repeated as needed to ensure thorough cleaning.

[0104] In addition, it should be noted that when there is a need to recycle the liquid, the liquid separation pump of the material separation device 60 can also be reversely started. For example, when the biological reagent is very precious and expensive, the liquid separation pump can also be reversely started after packaging to make the residual biological reagent in the corresponding flow path flow back to the storage container 14 of the original feeding device 1001 to reduce loss and save costs.

[0105] It is further understood that multiple cleaning liquids and gases can also be provided. For example, the feed source 15 in the feeding device ⑨ can be configured as ethanol, and the feed source 15 in the feeding device ⑧ can be configured as distilled water. After the pipeline is cleaned and sterilized using the ethanol in the feeding device ⑨, it can be cleaned again using the distilled water in the feeding device ⑧, and then the residual liquid in the flow path can be emptied and dried using clean air. In other words, the cleaning strategy and the emptying strategy can be designed according to the cleaning difficulty and requirements of different reagents. When the reagent cleaning difficulty is high, it can be repeatedly switched between cleaning with the cleaning liquid and emptying with the gas to achieve the purpose of cleaning.

[0106] In summary, the in-situ cleaning and dispensing system 100 provided in the present application, in which the cleaning multi-way valve group 70 and the material delivery multi-way valve 40 serve as two intermediate valve stations to cooperate with the reversing valve 11 of each feeding device 1001, and can open and close the flow of any flow path and switch the output of any feeding source 15 according to needs, to complete the in-situ cleaning, in-situ feeding and in-situ dispensing processes, effectively solve the problems of cross-contamination during material storage, material access and material switching, and greatly improve the packaging efficiency, packaging convenience and packaging safety.

[0107] See also Figure 5 The present invention further provides a liquid-separating multi-way head 50, which includes a main flow channel 52 and a plurality of branch flow channels 51, wherein one end of the plurality of branch flow channels 51 is connected to the same end of the main flow channel 52;

[0108] Multiple branch channels 51 are symmetrically arranged along the central axis of the main channel 52, and each branch channel 51 has an angle with the central axis of the main channel 52, which is a right angle or an acute angle. In this way, each branch channel 51 has equal resistance, which facilitates uniform and stable liquid separation.

[0109] Furthermore, the central axes of the multiple branch flow channels 51 intersect at the same point on the central axis of the main flow channel 52; and / or, the flow channel shapes of the multiple branch flow channels 51 are the same; and / or, the inner wall finish of the multiple branch flow channels 51 is the same; and / or, the flow channel lengths of the multiple branch flow channels 51 are equal; and / or, the inner diameters of the multiple branch flow channels 51 are equal. In this way, it is possible to further ensure that the resistance, flow velocity, and flow rate of each flow channel are equal, and further reduce the risk of uneven flow rate in each branch flow channel 51. In addition, the smooth inner wall of the flow channel and the smooth structural transition can further avoid the occurrence of cleaning dead corners.

[0110] Exemplarily, the degree of the angle is defined as a, 20°≤a≤60°. In this way, the air bubbles in the flow channel are discharged while the fluid flow is facilitated.

[0111] In one embodiment, each branch flow channel 51 includes a confluence section 511 and a joint section 512 that are coaxially arranged and interconnected, and one end of the confluence section 511 away from the joint section 512 is connected to the main flow channel 52, and the joint section 512 is used to connect the material distribution device 60; the inner diameter of the joint section 512 is larger than the inner diameter of the confluence section 511, so as to form a sealing end face 513 at the junction of the joint section 512 and the confluence section 511. The sealing end face 513 is used to be sealed and connected with the external component. In this way, the external component can achieve equal diameter end-to-end sealing between the sealing end face 513 and the liquid separation multi-way head 50, which is conducive to achieving no fluid dead zone, avoiding liquid accumulation and incomplete cleaning.

[0112] See also Figure 5 Furthermore, the joint section 512 is provided with an internal thread. Thus, the joint section 512 can be threadedly connected with the external component, thereby increasing the reliability of connection and sealing.

[0115] In one embodiment, the anti-return structure 953 is configured as a part of the tube body of the collection tube 952, and the part of the tube body is bent in a U-shape to form a liquid-sealed buffer chamber into which a barrier liquid can be injected. In this way, when the collected material is a gas or a volatile liquid, the loss of the collected material due to the return flow can be effectively avoided, and the pollution problem caused by the return flow can be avoided.

[0116] Furthermore, the collecting device 95 is also provided with a liquid sealing structure, which is arranged between the input port and the liquid sealing buffer chamber and is used to inject the barrier liquid into the liquid sealing buffer chamber.

[0117] In one embodiment, the anti-return structure 953 is configured as a one-way valve or a floating valve. It is understood that in other embodiments, the anti-return structure 953 can also be configured as other types of valve bodies that can play a blocking role.
