[0015] (III) Beneficial Effects

[0016] This utility model provides a waste liquid collection device for a biochemical analyzer, which has the following beneficial effects: 1. This waste liquid collection device for a biochemical analyzer, through the arrangement of a conveying component and a pushing component, allows the biochemical analyzer body to discharge waste liquid into the collection tank along the connecting pipe via an internal pump-liquid conveying system during use. The waste liquid then passes through a filter screen to separate impurities from the liquid. When there are too many impurities in the filter screen, a vibration motor is activated, causing the filter screen to vibrate on a spring. Simultaneously, a conveying pump is activated to extract the filtered liquid from the bottom, conveying it along the conveying pipe to the connecting pipe, and spraying it out from a high-pressure flushing nozzle at the bottom. A synchronous motor drives a threaded rod to rotate simultaneously, and a pusher block moves the connecting pipe to flush the liquid. Impurities enter the waste collection tank along the partition, thus preventing filter screen blockage and improving filtration efficiency. At the same time, the high-pressure flushing nozzle washes the filter screen, further removing residual impurities, reducing manual intervention, and lowering the risk of leakage.

[0017] 2. The waste liquid collection device of this biochemical analyzer, through the setting of the telescopic component, allows the waste liquid to enter through the through hole on the positioning plate when it enters from the connecting pipe, and squeezes the piston, causing the telescopic spring to deform under force and generate elastic force. Then the piston moves to the cavity, and the waste liquid enters the collection tank. When the waste liquid discharge ends, the telescopic spring pulls the piston to re-seal the pipe in order to restore its deformation, thereby avoiding the evaporation or backflow of residual waste liquid and causing pipe pollution, while reducing the impact of sudden changes in waste liquid flow rate on the system.

The filter screen 10 facilitates the filtration of impurities. A conveying component 3 is connected through to one side of the bottom of the collection box 2. The conveying component 3 and the pushing component 5 prevent the filter screen 10 from clogging and improve the filtration efficiency. At the same time, a high-pressure flushing nozzle 22 flushes the filter screen 10 to further remove residual impurities, reduce manual intervention, and reduce the risk of leakage. A connecting pipe 4 is connected through to one end of the conveying component 3, and pushing components 5 are fixedly connected to both ends of the connecting pipe 4. A connecting pipe 6 is connected through to the top of the collection box 2, and a positioning piece 7 is sleeved inside the connecting pipe 6. A telescopic component 8 is fixedly connected to the bottom of the positioning piece 7. The telescopic component 8 prevents residual waste liquid from evaporating or flowing back and causing pipeline blockage. To reduce pollution and minimize the impact of sudden changes in wastewater flow rate on the system, the conveying assembly 3 includes a conveying pump 301 connected to one side of the bottom of the collection tank 2, with a conveying pipe 302 connected to the output end of the pump 301. The pushing assembly 5 includes push blocks 501 fixedly connected to both ends of the connecting pipe 4, with a threaded rod 502 threadedly connected inside the push blocks 501. A synchronous motor 17 is fixedly connected to one end of the threaded rod 502, and a support shell 18 is fitted onto the surface of the synchronous motor 17. A slide rail 19 is rotatably connected to the surface of the threaded rod 502, and the push blocks 501 are slidably connected inside the slide rail 19. The push blocks 501 drive the connecting pipe 4. The telescopic assembly 8 includes a telescopic spring 801 fixedly connected to the bottom of the positioning plate 7, with a piston 802 fixedly connected to the bottom of the telescopic spring 801.

[0022] Furthermore, several sets of elastic devices 11 are fixedly connected to the bottom of both sides of the filter screen 10. Support bars 12 are fixedly connected to the bottom of each elastic device 11 and are fixedly connected to one side of the support frame 9. The support bars 12 provide support for the elastic devices 11. A support plate 13 is fixedly connected to the bottom of the filter screen 10, and a vibration motor 14 is fixedly connected to the bottom of the support plate 13. The vibration motor 14 drives the filter screen 10 to vibrate. A partition 15 is fixedly connected to one side of the collection box 2, and a waste collection trough 16 is slidably connected to one side of the collection box 2. The waste collection trough 16 facilitates the collection of impurities. Two sets of sliding grooves 20 are fixedly connected to the inner walls of both sides of the collection box 2. Activated carbon filters 21 are slidably connected inside the sliding grooves 20, further filtering harmful substances in the waste liquid. Several sets of high-pressure flushing nozzles 22 are provided at the bottom of the connecting pipe 4. A positioning rod 23 is fixedly connected to the top of the piston 802. The positioning rod 23 is slidably connected to the inside of the positioning plate 7. The positioning rod 23 plays a role in maintaining the stability of the piston 802 movement.

[0023] In this invention, the working steps of the device are as follows: First step: During use, the biochemical analyzer body 1 discharges waste liquid into the collection tank 2 through the internal pump liquid delivery system along the connecting pipe 6. Then, the impurities and liquid in the waste liquid are separated by the filter screen 10. When there are too many impurities in the filter screen 10, the vibration motor 14 is started, which makes the filter screen 10 shake on the elastic device 11. At the same time, the delivery pump 301 is started to draw out the liquid after filtration at the bottom, which reaches the connecting pipe 4 along the delivery pipe 302 and is sprayed out from the high pressure flushing nozzle 22 at the bottom. Then, the synchronous motor 17 drives the threaded rod 502 to rotate at the same time, and the push block 501 drives the connecting pipe 4 to move and flush. The impurities enter the waste collection tank 16 along the partition plate 15. The second step: When the waste liquid enters from the connecting pipe 6, it enters through the through hole on the positioning plate 7 and squeezes the piston 802, causing the telescopic spring 801 to deform under force and generate elastic force. Then the piston 802 moves to the cavity, and the waste liquid enters the collection box 2. When the waste liquid is discharged, the telescopic spring 801 pulls the piston 802 to re-seal the pipe in order to restore its deformation.
