Figure 2 A schematic structural diagram of another biochip cleaning and drying device provided in some embodiments of the present application. Figure 3 A cross-sectional view of a biochip cleaning and drying device provided in accordance with some embodiments of the present application.

[0047] The embodiment of the present application provides a cleaning and drying device for a biochip, comprising a box body 1, an adjusting rod 2 and a connecting seat 3, wherein a mounting seat 11 is arranged in the box body 1; the adjusting rod 2 is located in the box body 1, and one end of the adjusting rod 2 is fixed on the mounting seat 11, and the connecting seat 3 is located in the box body 1, a rotating hole 33 is opened on the connecting seat 3, the other end of the adjusting rod 2 is inserted into the rotating hole 33, the connecting seat 3 can rotate around the adjusting rod 2, and a nozzle is arranged on the connecting seat 3, the nozzle comprises a water spray nozzle 32 and an air blowing nozzle 31, one end of the air blowing nozzle 31 is connected to an air pipe arranged outside the box body 1 to provide a purge gas for the biochip 10, and one end of the water spray nozzle 32 is connected to a water pipe arranged outside the box body 1 to provide a cleaning liquid for the biochip 10.

[0048] In the embodiment of the present application, a mounting seat 11 is provided in the box body 1, the adjusting rod 2 is fixed on the mounting seat 11, and the connecting seat 3 rotates around the adjusting rod 2, so as to adjust and control the spraying angle of the nozzle on the connecting seat 3, thereby enabling the biochip 10 to be fully cleaned and dried, thereby avoiding damage or contamination of the biochip 10, and preventing the chip from being completely dried and liquid from remaining on the chip, which seriously affects the quality of the next process.

[0049] The cleaning and drying device of the biochip is an important device in the use of the biochip 10. After the detection, some biological solution extracted during the detection will remain on the biochip 10. In order to ensure the accuracy of the detection of the biochip 10, relevant technicians will use the cleaning and drying device of the biochip 10 to assist the cleaning work of the biochip 10.

[0050] The box body 1 is a carrier of the cleaning and drying device of the biochip, and is used to support and carry the cleaning mechanism and the drying mechanism to form the cleaning and drying device. In the embodiment of the present application, it is used to support and carry the connecting seat 3 and the adjusting rod 2.

[0051] Optionally, the box body 1 is made of corrosion-resistant material. The box body 1 made of corrosion-resistant material can avoid being corroded by the biological solution adhering to the biochip 10, which may cause damage to the box body 1 and reduce the service life of the box body 1.

[0052] At the same time, the mounting seat 11 in the box body 1 can also be made of corrosion-resistant material, thereby extending the service life of the mounting seat 11.

[0053] The connection seat 3 is equipped with a cleaning nozzle and a drying nozzle for realizing the cleaning and drying functions.

[0054] The adjusting rod 2 is arranged in the box body 1 and is rotatably connected with the connecting seat 3 so that the angle of the connecting seat 3 can be adjusted.

[0055] Optionally, in some embodiments, the box body 1 and the mounting seat 11 are an integrally formed structure. By setting the box body 1 and the mounting seat 11 as an integrally formed structure, on the one hand, there is no need to connect the box body 1 and the mounting seat 11 through additional connection processes such as welding or bonding, thereby simplifying the manufacturing process. At the same time, compared with connecting the box body 1 and the mounting seat 11 through connection processes such as welding or bonding, the box body 1 and the mounting seat 11 in an integral structure have a higher connection firmness, thereby being able to improve the overall structural strength of the cleaning and drying device of the biochip. Of course, in other embodiments, the box body 1 and the mounting seat 11 may also adopt a split structure, which are prepared separately and then connected and fixed by welding or the like, which will not be repeated here.

[0056] In addition, by dividing the water spray nozzle 32 and the air nozzle into two independent parts, it is possible to avoid that when one of the water spray nozzle 32 and the air nozzle is damaged, the other also needs to be repaired or replaced, thereby reducing the replacement cost.

[0057] refer to Figure 1 , Figure 2 and Figure 4 As shown, Figure 4 A schematic structural diagram of an adjusting rod 2 and a connecting seat 3 of another biochip cleaning and drying device provided in some embodiments of the present application.

[0058] In one of the embodiments, the cleaning and drying device of the biochip also includes a fastener 4, a fixing hole 34 is opened on the connecting seat 3, the fixing hole 34 is perpendicular to the rotating hole 33 and is connected to the rotating hole 33, the fastener 4 is passed through the fixing hole 34, and the fastener 4 can abut against the adjusting rod 2 to fix the position of the connecting seat 3 on the adjusting rod 2.

[0059] By opening a fixing hole 34 connected to the rotating hole 33 on the connecting seat 3, and then passing a fastener 4 through the fixing hole 34 to abut against the adjusting rod 2, the position of the connecting seat 3 on the adjusting rod 2 is fixed, so that the angles of the water nozzle 32 and the air blowing nozzle 31 relative to the biochip 10 are fixed, thereby achieving accurate cleaning and drying of a certain position on the biochip 10.

[0060] Optionally, in an embodiment of the present application, the fixing hole 34 is a threaded hole, and the fastener 4 is a bolt. The bolt is rotated into or out of the threaded hole through the thread to fix the connecting seat 3. The fixing hole 34 and the fastener 4 are arranged as a threaded hole and a bolt, which can be convenient for staff to operate and adjust, thereby further accelerating the cleaning efficiency of the biochip 10.

[0061] In addition, in the embodiment of the present application, the end of the adjusting rod 2 connected to the connecting seat 3 is cylindrical, and the rotating hole 33 connecting the connecting seat 3 to the adjusting seat is a cylindrical countersunk hole. However, the end of the bolt in contact with the adjusting rod 2 is usually a circular plane, so the contact area of ​​the end in contact with the adjusting rod 2 is small, resulting in a poor fixing effect. Therefore, a protrusion can be provided at the end of the bolt in contact with the adjusting rod 2 to increase the contact area, thereby greatly improving the fixing effect and preventing the connecting seat 3 from loosening during the process of cleaning or drying the biochip 10.

[0062] In one embodiment, the adjusting rod 2 is slidably disposed on the mounting seat 11 along its length direction.

[0063] The adjusting rod 2 is slidably connected to the mounting seat 11 , so that the position of the connecting seat 3 along the length direction of the adjusting rod 2 can be adjusted, thereby expanding the applicable range of the water spray nozzle 32 and the air blowing nozzle 31 on the connecting seat 3 .

[0064] Optionally, the adjusting rod 2 is fixed to the mounting seat 11 by means of a snap connection, and one of the adjusting rod 2 and the mounting seat 11 is provided with a snap convex, and the other is provided with a snap groove. There may be multiple snap grooves, which are arranged in sequence along the length direction of the adjusting rod 2, so that the position of the adjusting rod 2 on the mounting seat 11 along its own length direction can be adjusted. Compared with the traditional welding connection method, the snap connection method does not require the use of high-temperature welding equipment, and the installation site is safer without open flames, while reducing production costs and installation difficulties. In addition, the snap connection method is easy and quick to operate, can save tedious preparation work and waiting time, improve construction efficiency, and save time cost. In addition, the snap connection method not only has a low operating cost, but also can be quickly disassembled and adjusted during use and maintenance, and can be reused after disassembly, thereby reducing material loss and energy consumption, reducing production costs, and is an economical and practical connection method.

[0065] In one embodiment, the biochip cleaning and drying device further comprises a fixing seat 5, the fixing seat 5 is fixed on the mounting seat 11, the adjusting rod 2 is located between the fixing seat 5 and the mounting seat 11, and the fixing seat 5 is used to fix the position of the adjusting rod 2 on the mounting seat 11.

[0066] By setting the fixing seat 5 and setting the adjusting rod 2 between the fixing seat 5 and the mounting seat 11, the position of the adjusting rod 2 on the mounting seat 11 is further fixed, making the connection between the adjusting seat and the mounting seat 11 more firm, thereby improving the overall structural strength of the cleaning and drying device of the biochip 10.

[0067] like Figure 5 and Figure 6 As shown, Figure 5A schematic structural diagram of a box body 1 of another biochip cleaning and drying device provided in some embodiments of the present application. Figure 6 A schematic structural diagram of a box body 1 of another biochip cleaning and drying device provided in some embodiments of the present application.

[0068] In one embodiment, an opening 12 is formed on the side wall of the box body 1 , and the connecting seat 3 is at least partially located at the opening 12 .

[0069] The opening 12 can be provided to facilitate connection between the water spray nozzle 32 and the air blowing nozzle 31 on the connection seat 3 and the external water supply mechanism and air supply mechanism, thereby avoiding wear between the water pipe, the air pipe and the box body 1, and reducing the service life of the water pipe, the air pipe and the box body 1.

[0070] In one embodiment, the box body 1 is formed by vertically enclosing a first side wall 13 , a second side wall 14 , a third side wall 15 and a fourth side wall 16 in sequence, the first side wall 13 is arranged opposite to the third side wall 15 , and the second side wall 14 is arranged opposite to the fourth side wall 16 .

[0071] In the embodiment of the present application, the connecting seat 3 includes two first seat bodies 35 and two second seat bodies 36, the two first seat bodies 35 are respectively fixedly connected to the first side wall 13 and the third side wall 15, and the first seat body 35 is provided with an air blowing nozzle 31; and, the two second seat bodies 36 are respectively fixed to the second side wall 14 and the fourth side wall 16, and the first seat body 35 is provided with an air blowing nozzle 31; wherein the air blowing nozzle 31 on the first seat body 35 and the air blowing nozzle 31 on the second seat body 36 are respectively connected to their corresponding air pipes.

[0072] By respectively arranging the air blowing nozzles 31 on the two first base bodies 35 and the two second base bodies 36, it is possible to simultaneously blow air on the four surfaces of the biochip 10, thereby greatly improving the drying effect of the biochip 10 and improving the drying efficiency.

[0073] In one embodiment, a water spray nozzle 32 is further disposed on the first seat body 35 , and the water spray nozzles 32 on the first seat body 35 are respectively connected to corresponding water pipes.

[0074] By arranging water nozzles 32 on the two first seat bodies 35, it is possible to flush the two opposite surfaces of the biochip 10, thereby achieving the flushing effect of the biochip 10. Of course, in other embodiments, water nozzles 32 can also be arranged on the two second seat bodies 36. However, due to actual usage scenarios and manufacturing cost considerations, in this embodiment, water nozzles 32 are only arranged on the two first seat bodies 35.

[0075] like Figure 1-Figure 2As shown, in one of the embodiments, an air circuit adapter 7 and a liquid circuit adapter 8 are also provided on one end of the connecting base 3 away from the water nozzle 32 and the air nozzle. One end of the air circuit adapter 7 is connected to the air nozzle, and the other end is connected to the air pipe. One end of the liquid circuit adapter 8 is connected to the water nozzle 32, and the other end is connected to the water pipe.

[0076] By providing the gas circuit adapter 7 and the liquid circuit adapter 8, the structure of the flushing and drying assembly inside the box body 1 is made more compact, and both the air pipe and the water pipe can be connected to the box body 1 through the gas circuit adapter 7 and the liquid circuit adapter 8, which reduces the number of parts, reduces the cost of processed parts, and improves the convenience of pipeline assembly and replacement. In addition, a pipeline adapter is reserved outside the cleaning box body 1 so that the cleaning box body 1 can be modularized, so that the structural assembly and pipeline layout can be independent of each other.

[0077] like Figure 1-Figure 2 As shown, in one of the embodiments, the cleaning and drying device of the biochip also includes a waste liquid recovery bucket 6, which is arranged outside the box body 1 and connected to the box body 1. A through hole is opened at the bottom of the box body 1 to connect the waste liquid recovery bucket 6 with the box body 1.

[0078] By setting a waste liquid recovery bucket 6 at the bottom of the box body 1, the water nozzle 32 and the air nozzle spray liquid and gas respectively to rinse and dry the biochip 10. The waste liquid after rinsing can flow into the waste liquid recovery bucket 6 to collect and process the waste liquid, thereby preventing the waste liquid from flowing out and polluting the working environment.

[0079] like Figure 3 and Figure 6 As shown, in one embodiment, a collecting groove is provided at the bottom of the box body 1, and the collecting groove is funnel-shaped, and the bottom of the collecting groove is connected to the waste liquid recovery bucket 6. The recovery groove 17 includes four recovery parts, and the four recovery parts are respectively connected to the first side wall 13, the second side wall 14, the third side wall 15 and the fourth side wall 16. By providing a funnel-shaped collecting groove at the bottom of the box body 1, it is possible to facilitate the waste liquid to flow into the waste liquid recovery bucket 6, thereby preventing the waste liquid from accumulating in the box body 1, corroding the box body 1 and various components in the box body 1, causing the box body 1 and various components in the box body 1 to be damaged, and reducing the service life.

[0080] In one embodiment, the biochip cleaning and drying device further comprises a cover body, which is disposed on the top of the box body 1. The cover body is provided with an inlet, and the biochip 10 can enter the box body 1 through the inlet for cleaning and drying.

[0081] By arranging the cover body on the box body 1 , during the cleaning and drying process of the biochip 10 , waste liquid can be splashed out of the box body 1 to pollute the working environment.

[0082] In some embodiments, in addition to the components of the cleaning box 1, the entire instrument also includes other components such as a cylinder, a water pump, a clamp and a robotic arm, and they are also involved in the rinsing and drying of the biochip 10.

[0083] Workflow:

[0084] First, adjust the angle of the connection seat 3. After the adjustment is completed, place the cover on the box body 1, and clamp the biochip 10 through the feeding port by the clamping claws to clamp the biochip 10 into the box body 1. At the same time, the water pump works, and the water nozzle 32 sprays liquid to rinse the front and back of the chip, and fully cleans all positions on the front and back of the chip. After the cleaning is completed, the cylinder starts to work and blows the four sides of the chip dry. The gas fully dries the residual liquid on the chip. Flushing the chip residue and blowing the chip dry can ensure the detection accuracy of the biochip 10, and can better prevent the residue and liquid from falling during the movement and contaminating the instrument and other samples. Finally, the waste liquid flows into the waste liquid recovery bucket 6 through the recovery tank 17.

[0085] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
