[0075] As an example, different from the general plastic sheet microfluidic chip that does not contain circuits, the microfluidic chip in this embodiment is manufactured based on CMOS technology combined with MEMS technology, in which circuits are integrated and can be miniaturized. Among them, fluid inlets and outlets, flow channels and part of the circuit (such as key components for performing electric drive) are manufactured using MEMS technology, and the CMOS circuit for realizing logic control is manufactured using CMOS technology.

[0076] As an example, see Figures 3 to 5 ,in, Figure 3 The schematic diagram of the three-dimensional structure of the chip packaging circuit board 2 is shown. In this embodiment, the chip packaging circuit board 2 is a PCB hard board, and the surface of the chip packaging circuit board 2 is provided with a pin pad 201 and a first circuit interface 202; Figure 4 The schematic diagram of the three-dimensional structure of the chip package base 3 is shown, and the chip package base 3 includes an input through hole 301 and an output through hole 302; Figure 5 The three-dimensional structure diagram of the input conduit 4 is shown. The input conduit 4 can be made of stainless steel or hard plastic capillaries. The output conduit 5 (not shown separately) adopts the same structure as the input conduit 4.

[0077] As an example, the microfluidic chip 1, the chip packaging circuit board 2, the chip packaging base 3, the input conduit 4 and the output conduit 5 can be pre-packaged together to form a microfluidic chip packaging structure.

[0078] As an example, the chip package base 3 is provided with a boss 303, the input through hole 301 and the output through hole 303 both penetrate the boss 303 from top to bottom, the microfluidic chip 1 is placed on the boss 303 with the front side facing downward, and the input through hole 301 is aligned with the fluid inlet 101, and the output through hole 302 is aligned with the fluid outlet 102. The chip package circuit board 2 is provided with a receiving groove 203, the receiving groove 203 penetrates the chip package circuit board 2 from top to bottom, the boss 303 extends into the receiving groove 203, and the microfluidic chip is located in the receiving groove 203, and the pin pad 201 of the chip package circuit board 2 and the chip lead pin 103 of the microfluidic chip 1 can be connected by wire bonding technology through a wire (not shown).

[0079] See also Figure 8 , which is a schematic diagram of the three-dimensional structure of the wireless control circuit board 6, and the wireless control circuit board 6 includes a wireless communication module and a second circuit interface 601. When the microfluidic chip packaging structure is connected to the second circuit interface 601 of the wireless control circuit board 6 through the first circuit interface 201, the wireless control circuit board 6 receives an external control signal through the wireless communication module, and controls the operation of the microfluidic chip 1 according to the external control signal.

[0080] As an example, the wireless communication module 6 includes but is not limited to at least one of a WIFI module, a Bluetooth module, a Zigbee module and a millimeter wave module. Through the wireless communication module, any number of wireless microfluidic control modules can form a collaborative network to jointly complete complex microfluidic control operations.

[0081] As an example, the wireless control circuit board 6 is integrated with a power supply.

[0082] As an example, see Fig. 9 The wireless microfluidic control module further includes a snap bracket 7, and at least a part of the microfluidic chip packaging structure and the wireless control circuit board 6 are both snapped in the snap bracket 7 to improve contact stability, and the snap bracket 7 can also serve as a protective shell. After the microfluidic chip 1 is used, the microfluidic chip packaging structure can be removed from the snap bracket 7 as a whole, and a new microfluidic chip packaging structure can be replaced to connect with the wireless control circuit board 6, and the replacement process is convenient and quick.

[0083] See also Fig.10 and Fig.11 ,in, Fig.10 It is a schematic diagram of the exploded structure of the microfluidic chip packaging structure, the buckle bracket 7 and the wireless control circuit board 6 before assembly, Fig.11It shows a schematic diagram of the overall structure after the microfluidic chip packaging structure, the snap bracket 7 and the wireless control circuit board 6 are assembled.

[0085] As an example, the first circuit interface 202 includes a conductive contact (e.g., a conductive metal contact), which is located on the upper surface of the chip packaging circuit board 2, and the second circuit interface 601 includes a spring pin, which protrudes from the lower surface of the wireless control circuit board 6. With this circuit interface design, the microfluidic chip packaging structure and the wireless control circuit board 6 can be stacked vertically, which is conducive to miniaturization.

[0086] In other embodiments, the first circuit interface 202 and the second circuit interface 601 may also use other matching connectors, for example, the first circuit interface may include a conductive pin (such as an edge gold finger), the conductive pin protruding from the side of the chip packaging circuit board, and the second circuit interface includes a slot matching the conductive pin. Compared with the way that the conductive contact and the spring pin contact up and down, the edge contact method may cause the wireless microfluidic control module to occupy more area and be difficult to miniaturize.

[0087] It should be pointed out that, according to the different specific connection modes between the microfluidic chip packaging structure and the wireless control circuit board 6, the specific structure of the snap bracket can also be adjusted, and the protection scope of the present invention should not be excessively limited here.

[0088] In the wireless microfluidic control module of this embodiment, the microfluidic chip, chip packaging circuit board, chip packaging base, input conduit and output conduit microfluidic chip constitute a microfluidic chip packaging structure, wherein the chip packaging circuit board adopts a PCB hard board, and the electrical signal can be led out through the circuit interface. The microfluidic chip packaging structure and the wireless control circuit board can achieve fast and convenient electrical connection through a matching circuit interface, eliminating the cumbersome wiring connection process of the FPC soft board. At the same time, in the wireless microfluidic control module of this embodiment, the wireless control circuit board includes a wireless communication module, which can realize a collaborative network between any number of wireless microfluidic control modules to jointly complete complex microfluidic control operations.

The output port 810 is used to be connected to the input conduit of a micropump type wireless microfluidic control module 9, and the input port 811 is used to be connected to the output conduit of the micropump type wireless microfluidic control module 9.

[0092] As an example, the four micropump type wireless microfluidic control modules 9 cooperate to complete the fluid control operation, wherein the first micropump type wireless microfluidic control module and the second micropump type wireless microfluidic control module are turned on for 10 seconds at the same time, and the first liquid sample in the first liquid reservoir 801 and the second liquid sample in the second liquid reservoir 802 are driven to the fifth liquid reservoir 805. After 120 seconds of reaction, the third micropump type wireless microfluidic control module drives the third liquid sample in the third liquid reservoir 803 to the fifth liquid reservoir 805 to continue the reaction. After 50 seconds, the fourth micropump type wireless microfluidic control module drives the reacted liquid in the fifth liquid reservoir 805 to the fourth liquid reservoir 804, completing sample collection and subsequent experiments. The above is only an example. In other embodiments, the specific fluid control process can be adjusted as needed, and the microfluidic chip in the wireless microfluidic control module can also be of other types, such as microvalve, micromixer, microseparator, microdroplet generator, etc., and the protection scope of the present invention should not be excessively limited here.
