Referring to FIG. 1 and FIG. 2 together, the circuit board 100 of the embodiment of the present invention can be used in the biological detecting device 1000. The circuit board 100 includes a substrate 120 having a mounting surface 122, a connector 140 disposed at an edge 1222 of the mounting surface 122, and an electronic component 160 disposed on the mounting surface 122 and located inside the connector 140. The connector 140 is for connecting to the work device 200 through a cable.

Referring again to FIG. 2, the biodetection device 1000 of the present embodiment includes a circuit board 100 and a work device 200.

That is, the circuit board 100 of the embodiment of the present invention can be used for the bio-detection device 1000, or the bio-detection device 1000 of the embodiment of the present invention includes the circuit board 100 of the embodiment of the present invention. The circuit board 100 of the embodiment of the present invention sets the connector 140 that needs to be connected to the working device 200 at the edge 1222 of the mounting surface 122 of the substrate 120, thereby facilitating the insertion and removal of the working device 200, thereby reducing or avoiding the insertion of the working device 200. Pulling damage to other components of the board 100.

In certain embodiments, the biological detection device 1000 includes a genetic sequencing device including a laser, a fan, a camera, a switch, a photoelectric switch, a bubble sensor, a temperature sensor, a motor, a contact switch, an electromagnet, a power source, a solenoid valve, and the like.

The connector 140 refers to a connector for connection with the work device 200, and includes, for example, a USB, an HDMI connector, an IEEE connector, a radio frequency coaxial connector, and the like. The electronic component 160 includes a processing chip (such as an MCU, etc.) and common electronic components (resistors, capacitors, inductors, etc.).

In some embodiments, in order to facilitate placement and use of the circuit board 100, the connector 140 and the electronic component 160 are typically disposed on one of the mounting faces 122 of the substrate 120.

It will be appreciated that the edge 1222 of the mounting surface 122 is an area that is closer to the outer contour of the mounting surface 122 than the central portion of the mounting surface 122. In some examples, the edge 1222 refers to the area of the mounting surface 122 that is at a greater distance from the center point (not shown) of the mounting surface 122 than the predetermined distance to the outer contour. The preset distance can be set according to requirements. For example, when the number of the connectors 140 is relatively large, the preset distance can take a smaller value. Thus, the width of the edge 1222 is relatively large, and a larger number of connectors 140 can be set; When the number of connectors 140 is relatively small, the preset distance can take a larger value, and thus, the width of the edge 1222 is relatively small, satisfying the setting of a smaller number of connectors 140.

It should be noted that, in other embodiments, the preset distance may include multiple. In one example, the preset distance includes two, and the two preset distances are respectively a first preset distance and a second preset distance. The edge 1222 of the mounting surface 122 may refer to the center of the mounting surface 122 and the mounting surface 122. The lateral distance of the point is greater than the first predetermined distance or the area where the longitudinal distance is greater than the second predetermined distance.

In some embodiments, the circuit board 100 of the embodiment of the present invention can be applied to a desktop type detecting device such as a desktop type biological detecting device, a desktop cleaning robot, or the like. In this way, the performance of the desktop detecting device can be ensured, and the volume of the desktop detecting device can be reduced to enable the desktop detecting device to work normally in a small working space such as a desktop. In some embodiments, the substrate 120 is substantially rectangular and includes four edges 1222 along which the connectors 140 are distributed.

As such, the connectors 140 can be disposed on the four edges 1222, respectively, to facilitate connection of the external device 200 with the connector 140.

Specifically, when the circuit board 100 is cut, the rectangular circuit board is most conveniently cut and the material utilization rate is high, and therefore, the substrate 120 of the circuit board 100 can be designed to be rectangular. When the shape of the substrate 120 is a rectangle, that is, when the shape of the mounting surface 122 is a rectangle, the connector 140 can be disposed along the four edges 1222 of the rectangle, so that when the external arrangement 200 and the connector 140 need to be connected, it can be conveniently The external device 200 is coupled to the connector 140, and can shorten the length of the cable to which the external device 200 is connected to the connector 140 and prevent the cables from interlacing with each other.

In some embodiments, the substrate 120 may be designed in a circular shape, a square shape, a triangular shape, or the like according to requirements, and is not specifically limited herein. For example, in one embodiment, the space of the bio-detecting device 1000 for accommodating the circuit board 100 is cylindrical, and then designing the circuit board 100 to be circular helps to place the circuit board 100 into the accommodating space of the bio-detecting device 1000. .

Referring to FIG. 3, in some embodiments, the connector 140 includes a peripheral connector 142 and an inner perimeter connector 144 that is disposed inside the peripheral connector 142.

As such, the connector 140 can be reasonably set.

In some embodiments, the number of connectors 140 may be more, resulting in the connector 140 not being able to be disposed at a peripheral position of the edge 1222, so that the partial connector 140, that is, the peripheral connector 142, may be disposed at a peripheral position of the edge 1222. A portion of the connector 140, i.e., the inner perimeter connector 144, is disposed at the inner circumferential edge of the edge 1222. It should be noted that the peripheral position of the edge 1222 refers to the position of the edge 1222 of the mounting surface 122 near the outer contour of the mounting surface 122, and the inner circumferential position of the edge 1222 refers to the center of the mounting surface 122 near the mounting surface 122. The location of the point. Therefore, the inner peripheral connector 144 disposed inside the peripheral connector 142 means that the inner peripheral connector 144 is disposed on the edge 1222 near the center point of the mounting surface 122, and the peripheral connector 142 is disposed on the edge 1222 near the mounting surface 122. The position of the outer contour.

In some embodiments, the connector 140 includes multiple types, and the functions and connection structures of the plurality of connectors 140 of the same type are the same, and the functions and connection structures of the connectors 140 of any two types are different.

As such, the connection of the connector 140 of the same type and the corresponding external device 200 can be facilitated, and the problem that the connector 140 and the non-corresponding external device 200 are connected may cause damage to the circuit board 100.

Specifically, the connectors 140 having the same function may be referred to as the connectors 140 of the same type. If the connectors 140 of the same type include multiple, the multiple connectors 140 of the same type may adopt the same connection structure, for example, The connectors 140 connected to the laser are referred to as connectors 140 of the same type and employ the same connection structure. The same connection structure of the plurality of connectors 140 of the same type facilitates the connection of the connector 140 and the corresponding external device 200, so that one external device 200 can be connected with any one of the corresponding plurality of connectors 140 of the same type. The difference in the connection structure of any two types of connectors 140 can prevent the board 100 from being damaged due to the connection between the connector 140 and the non-corresponding external device 200, such as the connector 140 of the laser and the connector 140 of the power source. The same connection structure causes the power supply to be directly connected to the connector 140 of the laser due to the user's wrong connection, thereby causing damage to the circuit board 100.

In some embodiments, the same type of connector 140 includes multiple and adjacent arrangements. As such, it is convenient to connect the same type of connector 140 to the corresponding external device 200.

It can be understood that in order to ensure the tidyness and beauty of the external device 200, generally the same type of external device 200 (the external device 200 having the same function) is placed together, and therefore, in order to facilitate the connection of the same type of connector 140 with the corresponding external device 200 A plurality of connectors 140 of the same type may be adjacently arranged. In addition, a plurality of connectors 140 of the same type are disposed adjacent to each other such that a plurality of connectors 140 of the same type share a certain circuit structure, for example, a plurality of connectors 140 of the same type share a chip for detecting an operating current, and the like.
