DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following is a detailed description of the present utility model in conjunction with the drawings and embodiments:

[0027] The full-automatic biochemical analyzer described in the utility model includes an analyzer body 1. Two accommodating cavities 2 are recessed downward on the upper end surface of the analyzer body 1. Reagent bins 3 are arranged in both of the two accommodating cavities 2. A colorimetric cuvette 4 is arranged on the upper end surface of the analyzer body 1 between the two accommodating cavities 2. Two sampling needles 5 are also arranged on the upper end surface of the analyzer body 1. The reagent to be tested is placed in the left reagent bin 3, and the sample reagent is placed in the right reagent bin 3. The left sampling needle 5 is a reagent needle, and the right sampling needle 5 is a sample needle. Then, the reagent needle sucks the reagent from the reagent to be tested and puts it into the colorimetric cuvette 4, and the sample needle sucks the reagent from the sample reagent and puts it into the colorimetric cuvette 4. After the reaction, it is detected by a spectrophotometer, and a value is measured and transmitted to a computer to complete the test of the chemical components of the reagent. The sampling needle 5 is a prior art, which can rotate and move up and down, and can achieve the purpose of sucking the reagent and putting it into the colorimetric cuvette 4. The transmission mechanism of the sampling needle 5 will not be elaborated.

[0028] Since during measurement, the two sampling needles 5 continuously suck the reagent from the reagent bin 3 and put it into the colorimetric cuvette 4, after a long time of use, the upper end surface of the reagent bin 3 is likely to adhere to different reagents, and the reagent will also adhere to the jacks 6 in the reagent bin 3. Therefore, it is necessary to clean the reagent bin 3 regularly. To solve this problem, in this embodiment, a number of jacks 6 are evenly opened on the upper end surface of the reagent bin 3. Test tubes containing reagents are inserted into the jacks 6. The reagent bin 3 is sleeved with a plunger rod 7 through each jack 6. A driving device is arranged inside the analyzer body 1, and the driving device drives the plunger rod 7 to move up and down in the jack 6 of the reagent bin 3. During normal use, the driving device can adjust the up and down position of the plunger rod 7 in the jack 6 of the reagent bin 3 to adapt to reagent test tubes of different lengths. A number of drainage holes 8 are also opened on the reagent bin 3. The drainage holes 8 are evenly arranged along the circumference of the reagent bin 3. The top end of the drainage hole 8 is opened on the inner side wall of the corresponding jack 6, and the bottom end of the drainage hole 8 is opened on the lower part of the outer surface of the reagent bin 3. When it is necessary to clean the reagent bin 3, all the test tubes in the reagent bin 3 are taken out, and then clean water is poured into the accommodating cavity 2. Then, the driving device drives each plunger rod 7 to move up and down in the jack 6 of the reagent bin 3, so that the plunger rod 7 physically scrapes and cleans the inner side wall of the jack 6. Each time the plunger rod 7 moves downward, the top end of the plunger rod 7 will move below the top end of the drainage hole 8. At this time, part of the clean water will flow out along the jack 6 and the drainage hole 8. As the plunger rod 7 continuously moves up and down, clean water is continuously added into the accommodating cavity 2 to clean the reagent bin 3. The cleaning water flowing out from the bottom end of the drainage hole 8 enters the inside of the analyzer body 1, and then the cleaning water is centrally treated. Through holes corresponding to the drainage holes 8 are opened on the side wall of the accommodating cavity 2, which can allow the clean water to flow out through the through holes.

[0029] In order to achieve the purpose of synchronous movement of the plunger rods 7 in the two reagent bins 3, in this embodiment, bottom plates 9 are provided below the reagent bins 3 on both the left and right sides, and are fixedly arranged with the bottom ends of the corresponding plunger rods 7. A connecting plate 10 is fixedly arranged between the two bottom plates 9. An actuator block 11 is fixedly arranged on the lower end surface of the connecting plate 10. The driving device drives the actuator block 11 to move up and down, so as to achieve the purpose of each plunger rod 7 moving up and down in the insertion hole 6 of the reagent bin 3.

[0030] In order to achieve the purpose of driving the actuator block 11 to move up and down, in this embodiment, a guide post 12 is fixedly arranged on the side surface of the actuator block 11. A guide plate 13 is slidably arranged on the inner bottom wall of the analyzer body 1 in the left - right direction. A guide groove is formed on the side surface of the guide plate 13 close to the guide post 12. The free end of the guide post 12 is located in the guide groove. When the guide plate 13 moves left and right, the guide post 12 slides in the guide groove through the guide groove, and the guide groove enables the guide post 12 to move up and down. The guide post 12 then drives each plunger rod 7 to move up and down in the insertion hole 6 of the reagent bin 3 through the actuator block 11, the connecting plate 10 and the bottom plate 9 in sequence.

[0031] In this embodiment, the guide groove includes two inclined grooves 14 with their top ends connected. The two inclined grooves 14 are symmetrically arranged in the left - right direction. When the guide plate 13 moves left and right, when the guide post 12 is located at the bottom end of the inclined groove 14, the plunger rod 7 moves down to the lowest position. At this time, the top end of the plunger rod 7 is lower than the top end of the drainage hole 8. When the guide post 12 is located at the top end of the inclined groove 14, the plunger rod 7 is at the highest position.

[0032] In order to achieve the purpose of driving the guide plate 13 to move left and right, in this embodiment, a hydraulic telescopic rod 15 is fixedly arranged on the inner side wall of the analyzer body 1 in the left - right direction. The output end of the hydraulic telescopic rod 15 is fixedly provided with a connecting block 16. The left side surface of the connecting block 16 is fixedly arranged with the guide plate 13. The hydraulic telescopic rod 15 drives the guide plate 13 to move in the left - right direction through the connecting block 16.

[0033] In this embodiment, there are two guide plates 13, which are symmetrically arranged in the front and back on the front and back sides of the actuator block 11. Both of the two guide plates 13 are fixedly arranged with the connecting block 16. There are two guide posts 12, which are respectively fixedly arranged on the front side surface and the back side surface of the actuator block 11. The free ends of the two guide posts 12 are both located in the guide grooves of the corresponding guide plates 13. During use, the hydraulic telescopic rod 15 drives the two guide plates 13 to move in the left - right direction through the connecting block 16. The two guide plates 13 synchronously limit and drive the corresponding guide posts 12 to move up and down through the guide grooves. The two guide posts 12 jointly drive the actuator block 11 to move up and down.

[0034] For the purpose of discharging the clear water flowing out from the drain hole 8 from inside the analyzer body 1, in this embodiment, a space chamber 17 with a bottom surface inclined from left to right is provided below the inner bottom wall of the analyzer body 1. Communication holes 18 are evenly provided on the inner top wall of the space chamber 17, and an overflow hole 19 is provided on the right side surface of the space chamber 17; when cleaning the reagent cartridge 3, the clear water continuously flows out from the drain hole 8 of the reagent cartridge 3, gathers inside the analyzer body 1, and flows downward into the space chamber 17 through the communication holes 18. Then, the clear water entering the space chamber 17 flows from left to right to the right side and flows out from the overflow hole 19 and is discharged to the outside of the analyzer body 1; then, the cleaning water flowing out from the overflow hole 19 is collected and centrally processed.

[0035] The working principle of the present utility model is that during normal use, the reagent needle sucks the reagent from the reagent to be tested and places it into the colorimetric cell 4, and the sample needle sucks the reagent from the sample reagent and places it into the colorimetric cell 4. Then, after the reaction, it is detected by a spectrophotometer, and a value is measured and transmitted to the computer; when it is necessary to clean the reagent cartridge 3, all the test tubes in the reagent cartridge 3 are taken out, and then clear water is poured into the accommodating cavity 2. Then, the hydraulic telescopic rod 15 drives each plunger rod 7 to move up and down in the insertion hole 6 of the reagent cartridge 3 through the connecting block 16, the guiding plate 13, the guide post 12, the execution block 11 and the bottom plate 9 in sequence, so that the plunger rod 7 cleans the insertion hole 6 of the reagent cartridge 3. Each time the plunger rod 7 moves downward, the top end of the plunger rod 7 will move below the top end of the drain hole 8. At this time, a part of the clear water will flow out along the insertion hole 6 and the drain hole 8. As the plunger rod 7 continuously moves up and down, clear water is continuously added to the accommodating cavity 2. When cleaning the reagent cartridge 3, the clear water continuously flows out from the drain hole 8 of the reagent cartridge 3, gathers inside the analyzer body 1, and flows downward into the space chamber 17 through the communication holes 18. Then, the clear water entering the space chamber 17 flows from left to right to the right side and flows out from the overflow hole 19 and is discharged to the outside of the analyzer body 1; then, the cleaning water flowing out from the overflow hole 19 is collected and centrally processed.
