[0025] like Figure 1-3As shown, a variable microfluidic module of a delivery system proposed in an embodiment of the utility model comprises a lower mold 1 and an upper mold 2, a core plate 3 is inlaid and installed in the lower mold 1, a pad 4 is provided on the core plate 3, the pad 4 is inlaid and installed in the upper mold 2, the lower mold 1 and the upper mold 2 are fixed by bolts through an L-shaped connector 5, an inlet 6 and an outlet 7 are provided on the lower mold 1 and the upper mold 2, the inlet 6 and the outlet 7 are connected to the flow channel 8 on the core plate 3, a guide block 10 is provided inside the flow channel 8 on the core plate 3, a hollow hole 11 can be provided on the core plate 3, and screw holes 12 are provided on the lower mold 1 and the upper mold 2;

[0026] Lower mold 1 and upper mold 2: As the main structural body of the module, they provide support and installation space for internal components. They are fixed by L-shaped connectors 5 and bolts to ensure the overall stability and sealing of the module.

[0027] The core plate 3 is one of the core components of the module and is embedded in the lower mold 1. The flow channel 8 thereon is the main path for the fluid to flow. It also carries structures such as the guide block 10 and the hollow hole 11.

[0028] Pad 4: It is inlaid and installed in the upper mold 2 and cooperates with the core plate 3 to play a certain auxiliary and supporting role.

[0029] L-shaped connector 5: The lower mold 1 and the upper mold 2 can be firmly connected from both sides through four symmetrically arranged connectors and the bolt holes thereon, ensuring the stability of the structure under various use environments.

[0030] Inlet 6 and outlet 7: The inlet 6 is used for the introduction of fluid, and the outlet 7 is used for the output of fluid. They are connected with the flow channel 8 to realize the input and output channels of the fluid.

[0031] Flow channel 8: It is the main flow path of the fluid, and its design and layout determine the flow pattern and behavior of the fluid.

[0032] U-shaped plate 9: It plays the role of dividing the fluid in the flow channel 8, so that different fluids can be added simultaneously through the two inlets 6, thereby increasing the functionality and flexibility of the module.

[0033] The guide block 10 guides and regulates the fluid in the flow channel 8 and forms a U-shaped guide groove with the U-shaped plate 9 to achieve a specific fluid flow effect.
