[0046] like Figure 1-Figure 8As shown, this embodiment provides a highly efficient dustproof blood analyzer for laboratory, comprising an analyzer body 1, a transparent protective cover 2 is provided at the detection port at the front end of the analyzer body 1, a storage box 3 which is connected to the inside of the transparent protective cover 2 is provided on one side of the analyzer body 1, an air purification mechanism 4 is installed on the top of the storage box 3, the exhaust port of the air purification mechanism 4 is connected to the inside of the storage box 3, a sample placing port 5 is provided on the side of the front end of the storage box 3 away from the analyzer body 1, a transparent window 6 is provided on the outside of the storage box 3, a sample discharge port 7 is provided on the side of the front end of the storage box 3 close to the analyzer body 1, a conveying mechanism 8 is provided between the inside of the transparent protective cover 2 and the storage box 3, a storage mechanism 9 is provided inside the storage box 3 along the width direction, and a cap removal mechanism 11 is provided between the conveying mechanism 8 and the ends of the storage mechanism 9.

[0047] The general working principle is as follows: when in use, first open the air purification mechanism 4, input clean air into the storage box 3, discharge the dusty gas inside the storage box 3 and the transparent protective cover 2 to the outside of the equipment, and then insert the blood sample tubes with the test tube caps not removed from the sample opening 5 into the storage box 3, and use the storage mechanism 9 to store them in sequence. When analyzing the blood samples, the test tubes on the storage mechanism 9 are first passed through the uncapping mechanism 11 to remove the top test tube caps, and then the conveying mechanism 8 is used to convey the blood sample tubes toward the detection port of the analyzer body 1, and then the detection head on the analyzer body 1 is moved down and inserted into the test tubes to detect the blood samples, thereby ensuring the accuracy of the detection. When the detection is completed, the conveying mechanism 8 discharges the useless blood samples from the sample discharge port 7.

[0048] In this embodiment, a door panel 501 is hingedly mounted on the side of the lofting opening 5 , and a return spring 502 is provided between the inner side of the door panel 501 and the side of the lofting opening 5 .

[0049] Local working principle: The use of the door panel 501 at the sample opening 5 can effectively isolate the entry of external gas. At the same time, the use of the door panel 501 reduces the exhaust rate of the internal gas of the storage box 3.

[0050] In this embodiment, the conveying mechanism 8 includes a first roller 801, a second roller 802, a first rubber conveyor belt 803, a first limiting groove 804 and a conveying motor 805. The first roller 801 is rotatably installed below the detection port of the analyzer body 1, and the second roller 802 is rotatably installed inside the storage box 3. The first rubber conveyor belt 803 is installed between the first roller 801 and the second roller 802. The first limiting groove 804 is evenly and vertically opened on the outer side of the first rubber conveyor belt 803. A conveying motor 805 with an output end connected to the first roller 801 is installed below the detection port of the analyzer body 1.

[0051] Partial working principle: When the test tube is transported, the test tube is located inside the first limiting groove 804. By controlling the conveying motor 805 to drive the rotation of the first roller 801, the rotation of the first rubber conveyor belt 803 can be controlled, thereby controlling the movement of the test tube inside the first limiting groove 804.

[0052] In this embodiment, a stopper 702 is arranged on the inner side of the sample discharge port 7 so as to be inclined toward the first rubber conveyor belt 803, and the bottom end of the stopper 702 is in contact with the top of the first rubber conveyor belt 803, a receiving box 703 is arranged on the outer side of the sample discharge port 7, and a rubber partition 701 is symmetrically arranged on the inner side of the sample discharge port 7.

[0053] Local working principle: When the blood sample tube after testing moves toward the sample discharge port 7, since the top of the blood sample tube is higher than the first rubber conveyor belt 803, when it reaches the sample discharge port 7, as the first rubber conveyor belt 803 continues to move, the block 702 applies a thrust to the tube, squeezing it out from the sample discharge port 7 into the receiving box 703.

[0054] In this embodiment, the storage mechanism 9 includes a protective shell 901, a third roller 902, a fourth roller 903, a second rubber conveyor belt 904, a second limiting groove 905, a guide block 10 and a rotating assembly. The protective shell 901 is horizontally fixed inside the storage box 3, and a gap is left between the bottom end of the protective shell 901 and the inner bottom of the storage box 3. The second roller 802 is rotatably mounted on the front end of the protective shell 901, and the end of the protective shell 901 away from the second roller 802 is rotatably mounted with the third roller 902. The protective shell 901 A fourth roller 903 is rotatably installed on one end of 01 close to the second roller 802, a second rubber conveyor belt 904 is arranged between the third roller 902 and the fourth roller 903, second limiting grooves 905 are evenly arranged on the outer side of the second rubber conveyor belt 904, a guide block 10 is obliquely arranged on one side of the protective shell 901 close to the second roller 802, and the bottom of the guide block 10 is attached to the top of the second rubber conveyor belt 904, and a rotating component for controlling the rotation of the fourth roller 903 is arranged at the bottom of the protective shell 901.

[0055] Local working principle: When storing and transporting test tubes, the rotating component is used to control the second rubber conveyor belt 904 to rotate counterclockwise, and the test tubes can be stored at this time. When the rotating component controls the second rubber conveyor belt 904 to rotate clockwise, the test tubes will be transported. Since the horizontal plane of the sample opening 5 is higher than the horizontal plane of the bottom of the protective shell 901, the test tubes will not be discharged from the sample opening 5 during inspection and transportation. When the second rubber conveyor belt 904 drives the test tubes to move toward the first rubber conveyor belt 803, when the test tubes inside the second limiting groove 905 are aligned with the first limiting groove 804, as the second rubber conveyor belt 904 continues to move, the guide block 10 will apply thrust to the test tubes, pushing the test tubes into the first limiting groove 804 to complete the transfer of the test tubes.

[0056] In this embodiment, the rotating assembly includes a driving gear 906 and a driven gear 907. The driving gear 906 is located at the bottom of the protective shell 901, and the driving gear 906 is installed at the bottom end of the second roller 802. The driven gear 907 is installed at the bottom end of the fourth roller 903, and the driving gear 906 and the driven gear 907 are meshed.

[0057] Partial working principle: Since the driving gear 906 at the bottom end of the second roller 802 is meshed with the driven gear 907 at the bottom end of the fourth roller 903, the first rubber conveyor belt 803 and the second rubber conveyor belt 904 rotate synchronously, and the transportation of the test tube is more stable.

[0058] In this embodiment, the cap removal mechanism 11 includes a rubber column 1101, a rotating motor 1102, an electric telescopic rod 1103, a clamping plate 1104, a guide groove 1105, a rubber guide plate 1106 and a collection box 1107. The rotating motor 1102 is installed at the inner front end of the storage box 3. The output end of the rotating motor 1102 is installed with a rubber column 1101, and the rubber column 1101 is located at the top of the second rubber conveyor belt 904. The electric telescopic rod 1103 is installed below the rotating motor 1102. 03, and the output end of the electric telescopic rod 1103 faces the second rubber conveyor belt 904, a clamping plate 1104 is installed at the output end of the electric telescopic rod 1103, a guide groove 1105 is obliquely opened at the bottom of the electric telescopic rod 1103, a collecting box 1107 connected to the bottom end of the guide groove 1105 is provided at the front end of the storage box 3, the top of the guide groove 1105 and the protective shell 901 are located on the same horizontal plane, and the top of the guide groove 1105 is provided with a rubber guide plate 1106 that fits with the top of the protective shell 901.

[0059] Local working principle: when the test tubes on the second rubber conveyor belt 904 are conveyed toward the first rubber conveyor belt 803, after the test tubes are aligned with the ends of the splint 1104, the electric telescopic rod 1103 is started to control the splint 1104 to squeeze and fix the test tubes, and the rubber column 1101 contacts the test tube caps. The rotating motor 1102 controls the rubber column 1101 to rotate clockwise to remove the test tube caps, which fall into the gap between the second rubber conveyor belt 904 and the front end of the storage box 3. As another group of test tubes moves forward, the test tube caps are pushed into the guide groove 1105 by the rubber guide plate 1106 and stored in the collection box 1107.

[0060] In this embodiment, the air purification mechanism 4 includes a purification box 401, an air inlet 402, a filter 403, an air intake fan 404, a passage 405 and a dust removal component 406. The purification box 401 is fixed on the top of the storage box 3. The bottom of the purification box 401 is provided with a passage 405 which is connected to the storage box 3. The side of the purification box 401 is provided with an air inlet 402. The inside of the purification box 401 is provided with a filter 403 near the air inlet 402. The inside of the purification box 401 is provided with an air intake fan 404 near the passage 405. The outside of the filter 403 is provided with a dust removal component 406.

[0061] Partial working principle: When purifying the air, the air intake fan 404 is started to draw external gas into the purification box 401. After the external dust-containing gas is filtered by the filter 403, it enters the storage box 3 through the opening 405.

[0062] In this embodiment, the dust removal assembly 406 includes a rotating rod 4061, a shield 4062, a toothed disc 4063, a rack 4064, a vertical slot 4065, a tension spring 4066, a support rod 4067, a brush plate 4068 and an ash discharge port 4069. The rotating rod 4061 is evenly rotated and installed between the two ends of the air inlet 402. The shield 4062 is fixed on the air inlet 402, and the ends of the shield 4062 are fixed with a toothed disc 4063. The inner side of the purification box 401 is vertically slidably provided with a rack. 4064, the rack 4064 is meshed with multiple sets of toothed discs 4063, a vertical groove 4065 is provided at the bottom of the purification box 401, a tension spring 4066 is provided between the bottom end of the rack 4064 and the bottom end of the vertical groove 4065, a support rod 4067 is evenly fixed on the side of the rack 4064 away from the air inlet 402, a brush plate 4068 that fits the surface of the filter 403 is provided at the end of the support rod 4067 along the length direction of the filter 403, and a dust discharge port 4069 is provided at the bottom of the purification box 401.

[0063] Local working principle: when the air intake fan 404 is started, the interior of the purification box 401 is in a negative pressure state, and the gas will exert a certain thrust on the baffle 4062 when entering from the air inlet 402. At this time, the bottom end of the baffle 4062 is tilted toward the inside of the purification box 401, and when the baffle 4062 is tilted, the gear plate 4063 is controlled to rotate, and the rack 4064 is controlled to move upward. The rack 4064 moves upward and drives the brush plate 4068 to slide upward on the surface of the filter 403. When the detection is completed, the baffle 4062 is reset due to gravity. At this time, the rack 4064 drives the brush plate 4068 to move downward, and the brush plate 4068 automatically cleans the surface of the filter 403.

[0064] like Figure 1-Figure 8 As shown, this embodiment provides a highly efficient dustproof detection method for a blood analyzer in a laboratory as follows:

[0065] Step 1: Before use, start the air intake fan 404 to draw air from the outside, and after filtering and dust removal by the filter 403, the air enters the storage box 3. The pressure inside the storage box 3 increases, and clean air is discharged from the gap between the sample opening 5 and the sample discharge opening 7. The dusty air from the outside will not enter the storage box 3.

[0066] Step 2: When storing the blood sample, the conveying motor 805 is started to drive the first rubber conveyor belt 803 and the second roller 802 to rotate clockwise, and the rotation of the second roller 802 cooperates with the transmission of the gear to control the second rubber conveyor belt 904 to rotate counterclockwise, and the test tube is inserted from the sample opening 5 into the second limiting groove 905 to store the test tube;

[0067] Step 3: During the test, the conveying motor 805 drives the first rubber conveyor belt 803 to rotate counterclockwise, and the second rubber conveyor belt 904 drives the test tube to rotate clockwise. After the test tube is aligned with the end of the clamping plate 1104, the electric telescopic rod 1103 is started to control the clamping plate 1104 to squeeze and fix the test tube, and the rubber column 1101 contacts the test tube cap. The rotating motor 1102 controls the rubber column 1101 to rotate clockwise to remove the test tube cap, and the test tube cap falls into the gap between the second rubber conveyor belt 904 and the front end of the storage box 3. As another group of test tubes moves forward, the rubber guide plate 1106 pushes the test tube cap into the guide groove 1105 and stores it in the collection box 1107.
