[0038] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0039] Please refer to the attached Figures 1 to 6 , an embodiment of the present application provides a liquid addition assembly 100 for a biochip. The liquid addition assembly 100 is used to add liquid to the biochip. The liquid addition assembly 100 includes a base 10, an upper cover 20, a sealing ring 30, and a cover plate 40. The upper cover 20 is disposed on the upper side of the base 10. The sealing ring 30 is located between the upper cover 20 and the base 10. The cover plate 40 is disposed on the upper side of the upper cover 20.

[0040] In the embodiment of the present application, the base 10 serves as a support member of the biochip liquid adding assembly 100. The base 10 is used to support the upper cover 20, the sealing ring 30, and the cover plate 40. The base 10 is provided with a receiving groove 10a; the receiving groove 10a is recessed from top to bottom by the base 10. The receiving groove 10a is used to receive the biochip. The outer contour of the biochip is adapted to the inner contour of the receiving groove 10a, so that the biochip can be placed into the receiving groove 10a from top to bottom. The upper surface of the biochip is provided with a liquid adding area.

[0041] In the embodiment of the present application, the upper cover 20 is rotatably connected to the base 10 to facilitate adjusting the position of the upper cover 20 relative to the base 10. The upper cover 20 is closed towards the base 10; the upper cover 20 is located on the upper side of the base 10 and clamps the biochip in the receiving groove 10a with the base 10, so that the upper cover 20 restricts the upper end of the biochip, ensuring the position of the biochip relative to the receiving groove 10a; the upper cover 20 is provided with an opening 20a, and the opening 20a exposes the liquid adding area of the biochip; the opening 20a is used for liquid to pass through, so that the liquid can flow through the opening 20a to the liquid adding area of the biochip.

[0042] In the embodiment of the present application, the sealing ring 30 is located between the upper cover 20 and the base 10. The sealing ring 30 is connected to the lower surface of the upper cover 20. The sealing ring 30 hermetically contacts the upper surface of the biochip as the upper cover 20 closes towards the base 10, and is disposed around the outside of the liquid adding area, forming a sealed space, preventing the liquid in the liquid adding area from flowing out to the external environment through the connection between the upper cover 20 and the base 10 and preventing the leakage of the liquid in the liquid adding area.

[0043] In the embodiment of the present application, the cover plate 40 is located on the upper side of the upper cover 20 and closes the opening 20a of the upper cover 20. A liquid storage space 20b is formed among the cover plate 40, the opening 20a of the upper cover 20, the sealing ring 30, and the biochip. The liquid storage space 20b is used to store liquid. The liquid in the liquid storage space 20b contacts the liquid adding area of the biochip. At this time, the liquid enters the liquid adding area of the biochip through the opening 20a. At the same time, the liquid is stored in the liquid storage space 20b, and a sealed space is formed by the contact between the sealing ring 30 and the lower surface of the upper cover 20 and the upper surface of the biochip, thereby ensuring the storage of the liquid in the liquid storage space 20b and preventing the leakage of the liquid. At the same time, when replacing the liquid, only the cover plate 40 needs to be opened, and the liquid is exported out through the opening 20a, so as to replace other liquids for the liquid adding area of the biochip, avoiding the need to open the upper cover 20 and the base 10 when the liquid needs to be replaced, and improving the convenience of the biochip liquid adding assembly 100 for liquid.

[0044] The upper cover 20 and the base 10 are stacked in the up-down direction. The sealing ring 30 is located between the upper cover 20 and the biochip and is arranged around the outside of the liquid addition area, preventing the liquid in the liquid addition area from flowing out to the external environment through the outside of the liquid addition area and preventing the liquid leakage in the liquid addition area.

[0045] The lower side wall of the upper cover 20 is provided with an annular groove 20c. The sealing ring 30 is sealingly sleeved in the annular groove 20c, facilitating the accommodation of the sealing ring 30 in the upper cover 20 through the annular groove 20c. Thus, the inner side wall of the annular groove 20c restricts the position of the sealing ring 30, further ensuring the position accuracy of the sealing ring 30. The lower surface of the sealing ring 30 extends downward beyond the opening 20a of the annular groove 20c and sealingly contacts the upper surface of the biochip, enabling the upper cover 20 to be sealingly connected to the upper surface of the biochip through the sealing ring 30, and thus facilitating the sealing ring 30 to block the liquid in the liquid addition area from flowing out to the external environment.

[0046] The sealing ring 30 is located above the accommodation groove 10a and does not exceed the inner contour of the accommodation groove 10a, facilitating the sealing ring 30 to seal the gap between the accommodation groove 10a and the biochip, and thus preventing the liquid between the accommodation groove 10a and the biochip from flowing out to the external environment.

[0047] The cover plate 40 is located above the upper cover 20. The lower surface of the cover plate 40 contacts the upper surface of the upper cover 20 and can block or open the opening 20a of the upper cover 20, facilitating the connection or detachment of the cover plate 40 from the upper cover 20. When the cover plate 40 blocks the opening 20a of the upper cover 20, it prevents the liquid in the liquid addition area from flowing upward to the external environment. When the cover plate 40 opens the opening 20a of the upper cover 20, it facilitates the liquid to flow into the liquid addition area through the opening 20a.

[0048] The upper surface of the cover plate 40 is provided with a handle 41 for the user to hold, facilitating the user to lift the cover plate 40 through the handle 41, and thus improving the disassembly convenience of the cover plate 40.

[0049] The base 10 is provided with a column 11 at the rear side of the base 10. The upper cover 20 is rotatably connected to the column 11 and flips in the front-back direction, facilitating the adjustment of the position of the upper cover 20 relative to the column 11 to cover the base 10, and thus enabling the upper cover 20 to rotate relative to the base 10 through the column 11.

[0050] The base 10 is connected to a rotating pin 12. The rotating pin 12 is rotatably connected to the base 10 and flips in the up-down direction. This facilitates the adjustment of the position of the rotating pin 12 relative to the base 10. When the rotating pin 12 flips upward, it penetrates through the left or right side wall of the upper cover 20 and clamps the upper cover 20, facilitating the adjustment of the clamping force on the biochip between the base 10 and the upper cover 20 through the rotating pin 12.

[0051] The rear side wall of the upper cover 20 is connected to the column 11 through a hinge 13. The front side wall of the upper cover 20 is snap-fitted to the front side wall of the base 10, so that one end of the upper cover 20 can rotate relative to the column 11 through the hinge 13, and the other end of the upper cover 20 is fixed to or disengaged from the base 10.

[0052] A snap-fitting arm 14 is connected to the front side wall of the base 10. The snap-fitting arm 14 is rotatably connected to the base 10 to facilitate adjusting the position of the snap-fitting arm 14 relative to the base 10. The snap-fitting arm 14 is turned upward to be snap-fitted into the snap-fitting groove on the front side wall of the upper cover 20, so that the other end of the upper cover 20 can be snap-fitted to the base 10 through the snap-fitting arm 14. When the snap-fitting arm 14 disengages from the snap-fitting groove on the front side wall of the upper cover 20, the upper cover 20 can rotate relative to the column 11.
