[0024] The application provides a liquid discharging device, which can be used for discharging liquid in a liquid suction member. Please refer to Figure 1 、 Figure 2 The liquid discharging device 100 can include a support assembly 10, a fixing assembly 20, and a squeezing assembly 30. The support assembly 10 is used for supporting the fixing assembly 20 and the squeezing assembly 30. The fixing assembly 20 includes a fixing member 21, which is installed on the support assembly 10, and a fixing hole 211 is formed in the fixing member 21, which is used for accommodating a liquid discharging member 50. The liquid discharging member 50 includes a tube body 51 and a push rod 52. The tube body 51 is inserted into the fixing hole 211, so that the tube body 51 can be fixed on the fixing member 21, preventing the tube body 51 from being displaced during the liquid discharging operation, thereby facilitating the liquid discharging operation. The tube body 51 is provided with a cavity 511 for accommodating a liquid suction member, and the push rod 52 is partially arranged in the cavity 511. The push rod 52 is movably connected with the tube body 51, so that the push rod 52 can move relative to the tube body 51 when subjected to a pushing force, thereby squeezing the liquid suction member. One end of the tube body 51 is provided with a liquid discharging hole 512, which communicates with the cavity 511. When the push rod 52 squeezes the liquid suction member, the liquid suction member is compressed, and the liquid in the liquid suction member is discharged from the liquid discharging hole 512. The liquid discharging member 50 can be a disposable liquid discharging member or a non-disposable liquid discharging member. When the liquid discharging member 50 is a non-disposable liquid discharging member, the liquid discharging member 50 can be repeatedly used after being cleaned, thereby reducing the use cost. When the liquid discharging member 50 is a disposable liquid discharging member, a new liquid discharging member is used for each liquid discharging operation, thereby avoiding the interference of residual substances in the liquid discharging member 50 with the next test. Exemplarily, the liquid discharging member 50 can be a syringe. When the liquid discharging member 50 is a syringe, a needle can be installed at one end of the tube body 51, which is provided with the liquid discharging hole 512.

[0025] Please continue to refer to Figure 1The extrusion assembly 30 comprises a machine body 31 and an extrusion piece 32. The machine body 31 is installed on the support assembly 10. The machine body 31 is spaced apart from the fixing piece 21, so that the extrusion piece 32 has a certain movement stroke to facilitate the application of force to the push rod 52. The extrusion piece 32 is movably connected to the machine body 31. For example, a displacement channel 311 is formed in the machine body 31, and the extrusion piece 32 movably penetrates the displacement channel 311. The extrusion piece 32 can move in the displacement channel 311 along the extension direction of the displacement channel 311. The extrusion piece 32 is configured to push the push rod 52 to move axially to extrude the liquid suction piece accommodated in the cavity 511, so as to discharge the liquid in the liquid suction piece.

[0026] The liquid discharge device 100 provided in the present application has the fixing hole 211 formed in the fixing piece 21, and the tube body 51 is inserted into the fixing hole 211, so that the tube body 51 can be fixed on the fixing piece 21 to prevent the tube body 51 from being displaced during the liquid discharge operation, thereby facilitating the liquid discharge operation. The extrusion piece 32 is configured to push the push rod 52 to move axially to extrude the liquid suction piece accommodated in the cavity 511, so as to discharge the liquid in the liquid suction piece. The liquid suction piece can be pushed by the extrusion piece 32 to discharge the liquid. Compared with manually extruding the liquid suction piece to discharge the liquid, the liquid discharge device 100 can improve the efficiency of the liquid discharge operation and reduce the workload of manual operation.

[0027] A motor can be arranged in the machine body 31. The motor is drivingly connected to the extrusion piece 32. The motor drives the extrusion piece 32 to move, so as to push the push rod 52 to move axially. This can improve the efficiency of the liquid discharge operation and reduce the workload of manual operation.

[0028] In an embodiment, referring to Figure 3 The extrusion assembly 30 comprises an operating piece 33. One end of the operating piece 33 is drivingly connected to the extrusion piece 32. The one end of the operating piece 33 is used to apply an external force. The one end of the operating piece 33 for applying the external force can be located outside the machine body 31 to facilitate operation. The operating piece 33 is configured to drive the extrusion piece 32 to move under the action of the external force, so as to push the push rod 52 to move axially. The operating piece 33 and the extrusion piece 32 can be in gear transmission connection. For example, the extrusion piece 32 is provided with a toothed structure extending in the axial direction. One end of the operating piece 33 is connected to a gear. The gear is engaged with the toothed structure. The push rod 52 can move axially by rotating the operating piece 33. The operating piece 33 drives the extrusion piece 32 to move under the action of the external force. Compared with the motor driving the extrusion piece 32 to move, the liquid discharge device 100 does not need to consume electric energy during the liquid discharge operation, which can reduce the use cost of the liquid discharge device 100.

[0029] A clamp can be arranged on the outer periphery of the fixing hole 211, so as to clamp and fix the tube body 51 in the fixing hole 211 from the side.

The limiting flange 22 is arranged on the hole wall of the fixing hole 211 to fix the pipe body 51, and compared with clamping and fixing the pipe body 51 by the clamp, the material quantity of the fixing member 21 can be reduced, so that the production cost is reduced.

[0031] Referring to Figure 2 , Figure 3 In an embodiment, the fixing member 21 is provided with a limiting groove 212 on the side close to the pressing member 32, the limiting groove 212 is communicated with the fixing hole 211, when the pipe body 51 is inserted into the fixing hole 211, one end of the pipe body 51 away from the liquid discharge hole 512 is clamped in the limiting groove 212, so that the pipe body 51 is clamped and fixed in the fixing hole 211. The limiting groove 212 is arranged to fix the pipe body 51, and the material quantity of the fixing member 21 can be reduced, so that the production cost is reduced.

[0032] It can be understood that the fixing member 21 can be provided with only the limiting flange 22 or the limiting groove 212, or provided with both the limiting flange 22 and the limiting groove 212.

[0033] The fixing member 21 and the main body 31 of the machine body can be fixedly installed on the support assembly 10, so that the liquid discharge device 100 has good integrity.

[0034] In an embodiment, as Figure 3 shown, the support assembly 10 comprises a support column 11, the fixing member 21 and the main body 31 of the machine body are spacedly installed on the support column 11. The fixing member 21 and / or the main body 31 of the machine body are movably connected with the support column 11. At least one of the fixing member 21 and the main body 31 of the machine body is movably connected with the support column 11, so that the position of the fixing member 21 or the main body 31 of the machine body relative to the support column 11 is adjustable, so as to adjust the distance between the fixing member 21 and the main body 31 of the machine body, so that the fixing member 21 can fix liquid discharge members 50 of different specifications, thereby enhancing the versatility of the liquid discharge device 100.

[0035] The connection mode of the fixing member 21 or the main body 31 of the machine body with the support column 11 can be clamping or threaded connection. For example, the end of the fixing member 21 or the main body 31 of the machine body is connected with a buckle structure, and the fixing member 21 or the main body 31 of the machine body can be clamped on the support column 11 through the buckle structure.

[0036] In an embodiment, the fixing member 21 is movably connected with the support column 11, and the relative position between the fixing member 21 and the main body 31 of the fuselage can be changed by sliding the fixing member 21, so as to adjust the distance between the fixing member 21 and the main body 31 of the fuselage. For example, a hole is formed in the fixing member 21, and the support column 11 is arranged in the hole of the fixing member 21, so that the fixing member 21 can slide on the support column 11; or a sliding groove is formed in the support column 11, and the end of the fixing member 21 is accommodated in the sliding groove, so that the fixing member 21 can slide on the support column 11. Please refer to Figure 3 The connection between the fixing member 21 and the support column 11 is provided with a first locking member 23, and the first locking member 23 is used to lock the fixing member 21 on the support column 11, so that the fixing member 21 can be fixed on the support column 11 after the position is changed, thereby preventing the fixing member 21 from being displaced during the liquid discharge operation. The first locking member 23 can be a screw or a bolt, and a through hole is formed in the side wall of the fixing member 21, and the screw or the bolt passes through the through hole to fix the fixing member 21 on the support column 11.

[0037] In an embodiment, as shown in Figure 3 The main body 31 of the fuselage is movably connected with the support column 11, and the connection between the main body 31 of the fuselage and the support column 11 is provided with a second locking member 34, and the second locking member 34 is used to lock the main body 31 of the fuselage on the support column 11. The movable connection between the main body 31 of the fuselage and the support column 11 can refer to the movable connection between the fixing member 21 and the support column 11, and correspondingly, the arrangement of the second locking member 34 can refer to the arrangement of the first locking member 23.

[0038] The support assembly 10 can include one support column 11, or multiple support columns 11, for example, two, three, four or more. When the number of support columns 11 is greater than or equal to three, the multiple support columns 11 are respectively connected to the outer periphery of the fixing member 21 and the main body 31 of the fuselage, and the ends of the multiple support columns 11 can form a plane, thereby stably supporting the fixing assembly 20 and the extrusion assembly 30.

[0039] Please refer to Figure 3 In an embodiment, the support assembly 10 includes a base 12, and the support column 11 is connected to the base 12. The support column 11 is arranged to be connected to the base 12, the base 12 forms a support for the fixing assembly 20 and the extrusion assembly 30, and can stably support the fixing assembly 20 and the extrusion assembly 30, and at this time, the number of support columns 11 can be smaller, for example, the support column 11 can be one or two, thereby reducing the number of support columns 11.

[0040] In an embodiment, as shown in Figure 3As shown, one end of the pressing member 32 is provided with a first limiting member 35, and the other end of the pressing member 32 is provided with a second limiting member 36, which are used to limit the movement stroke of the pressing member 32 relative to the body 31. Exemplarily, the first limiting member 35 can be arranged at the end of the pressing member 32 away from the fixing member 21. The first limiting member 35 and the second limiting member 36 can be screws or flanges protruding from the fixing member 21. The first limiting member 35 can prevent the pressing member 32 from having too large a stroke when pushing the push rod 52, so as to prevent damage to the drainage member 50; and the second limiting member 36 can prevent the pressing member 32 from having too large a stroke when returning, so as to prevent the pressing member 32 from falling off the displacement channel 311.

[0041] Please refer to Figure 3 In an embodiment, the first limiting member 35 is in the shape of a rod, the extension direction of the first limiting member 35 is parallel to the extension direction of the pressing member 32, and the position of the first limiting member 35 relative to the pressing member 32 in the extension direction of the first limiting member 35 is configured to be adjustable. The first limiting member 35 can be threadedly connected with the pressing member 32, and the relative position of the first limiting member 35 and the pressing member 32 can be adjusted by rotating the first limiting member 35, so as to adjust the maximum stroke of the pressing member 32 when pushing the push rod 52, so that the pressing member 32 can apply force to drainage members 50 of different specifications, thereby enhancing the versatility of the drainage device 100.

[0042] In an embodiment, as Figure 3 shown, the drainage device 100 comprises a collection container 40 arranged near the end of the tube body 51 where the drainage hole 512 is arranged, and the collection container 40 is used to collect the liquid discharged by the liquid suction member. The collection container 40 can be a measuring cup, through which the discharge amount of the liquid can be read, so as to approximately obtain the liquid suction amount data of the liquid suction member, which can reduce the workload of subsequent testing of the liquid suction amount. In addition, the difference in adsorption of different components in the liquid by the liquid suction member can also be detected by detecting the change in the composition of the liquid in the collection container 40.

[0043] The following is an example ​The drainage device 100 shown in the middle is used to illustrate the drainage operation process. First, loosen the second locking member 34, adjust the height of the body 31 to the highest position of the support column 11, and tighten the second locking member 34 to fix the body 31. Open the push rod 52 of the drainage member 50, put the suction member into the pipe body 51, then install it into the push rod 52, fix the pipe body 51 on the fixing member 21, and expose the end of the pipe body 51 with the drainage hole 512 to the fixing hole 211. Loosen the first locking member 23, adjust the height of the fixing member 21 so that the push rod 52 can contact the end of the pressing member 32, and tighten the first locking member 23 to fix the fixing member 21. Place the collection container 40 on the base 12 so that the collection container 40 is located below the drainage hole 512 of the drainage member 50. Slowly press the operating member 33, which drives the pressing member 32 to move, and the pressing member 32 pushes the push rod 52 to squeeze the suction member, so that the liquid discharged from the suction member enters the collection container 40, until the push rod 52 is pressed to the bottom of the pipe body 51, and the drainage operation is completed. Compared with manually squeezing the suction member to drain, the drainage device 100 is more time-saving and labor-saving, which can improve the efficiency of the drainage operation and reduce the workload of manual operation.
