DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figure 1 The utility model provides a technical solution: an allergen fluorescent immunoassay analyzer.

[0024] Among them, disinfectant water is stored inside the disinfection base 1, an insulation board 101 is fixedly connected to the left side of the top of the disinfection base 1, a detection partition 103 is fixedly connected to the right side of the top of the disinfection base 1, a fluorescence analysis device 4 is arranged on the inner side of the top of the detection partition 103, a fixing rod 201 is fixedly connected between the side walls of the disinfection base 1, bearings 202 are sleeved on the left and right sides of the fixing rod 201, a connecting rod 203 is arranged between the two bearings 202, a motor 204 is arranged on the right side of the disinfection base 1, the motor 204 passes through the side wall of the disinfection base 1 and is connected to the connecting rod 203, a conveying rack 2 is arranged on the outside of the bearing 202, a sample box 3 is arranged between the two conveying racks 2, a pin 301 is installed through the sample box 3 near the bottom center, and a drying component 5 is arranged on the front of the disinfection base 1.

[0025] In this embodiment, two fixing rods 201 are fixedly connected inside the disinfection base 1. The right side of the fixing rod 201 is connected to the inner wall of the disinfection base 1. A hole with a diameter larger than the fixing rod 201 is opened on the disinfection base 1 at the corresponding position on the left side, and a bearing 202 is arranged in the hole. Similarly, a bearing 202 is also sleeved at the contact position between the right fixing rod 201 and the inner wall of the disinfection base 1. The two bearings 202 are exactly the same in size and are connected by four connecting rods 203. The left bearing 202 is connected to the motor 204, and the bearing 202 is driven to rotate by the motor 204. The outer side of the bearing 202 is close to the conveying frame 2. The conveying frame 2 is made of soft material and can be bent. As the bearing 202 rotates, the two conveying frames 2 rotate, driving the sample box 3 on the conveying frame 2 to rotate clockwise. The sample box 3 is fixed to the conveying frame 2 by the latch 301 and moves with the conveying frame 2. The direction is consistent, and the sample is placed in the sample box 3 at the top front end of the instrument. As the motor 204 rotates, the conveyor frame 2 is driven by the bearing 202 to transport the sample box 3 to the detection partition 103, and the fluorescence analysis device 4 detects the sample in the sample box 3. After the detection is completed, the motor 204 continues to rotate. When the sample box 3 moves to the inner end of the disinfection base 1, it will turn over as the direction of the conveyor frame 2 changes, and immerse in the disinfectant poured into the disinfection base 1. After being soaked in the disinfectant, it rises from the front end of the disinfection base 1. The disinfectant cleans the sample box 3 and removes the remaining sample traces. The conveyor frame 2 contacts the drying component 5, and the disinfectant is removed through the drying effect of the drying component 5. Finally, the sample box 3 is turned to be placed horizontally, and the sample can continue to be placed for detection, thereby avoiding contamination of the sample by multiple uses of the sample box 3.

[0026] Among them, a protective plate 503 is arranged on the back of the drying component 5, a heating wire 501 is arranged on the back of the protective plate 503, a fan 502 is arranged on the back of the heating wire 501, and heat dissipation holes 102 are opened on both sides of the heat insulation plate 101.

[0027] In this embodiment, the heating wire 501 and the fan 502 are connected through an external power supply. The heating wire 501 generates heat to heat the surrounding air. The fan 502 blows the hot air to the surface of the sample box 3. The hot air evaporates the disinfectant water and blows the disinfectant water away from the surface of the sample box 3, so that the sample box 3 becomes dry for continued use. The protective plate 503 can prevent people from contacting the heating wire 501 and causing burns. The heat dissipation holes 102 discharge the hot air to both sides to balance the air pressure inside and outside.

[0028] A guide plate 104 is disposed on the back of the disinfection base 1 , and a waste box 105 is disposed at the bottom of the guide plate 104 .

[0029] In this embodiment, after being detected by the fluorescence analysis equipment 4, the sample box 3 continues to be transported forward through the conveying rack 2, and turns to be vertically downward after passing the first fixed rod 201. The sample in the sample box 3 falls out of the sample box 3 due to the influence of gravity, and falls into the waste box 105 after hitting the guide plate 104. The top of the guide plate 104 is an inclined surface, which is higher near the disinfection base 1 and lower far from the disinfection base 1, thereby ensuring that the sample moves forward and enters the waste box 105, which is convenient for subsequent collection and sorting.

[0030] The fixing rods 201 between the heat insulation plates 101 are fixedly connected to the heat insulation plates 101 , and the fixing rods 201 between the detection partitions 103 are fixedly connected to the detection partitions 103 .

[0031] In this embodiment, two of the four fixed rods 201 are respectively arranged in the heat insulation board 101 and the detection partition 103. The heat insulation board 101 blocks the drying component 5 from blowing hot air toward the detection partition 103. The detection partition 103 protects the fluorescence analysis equipment 4 to reduce the interference of the external environment on the detection process.

[0032] The bearing 202 and the connection between the bearing 202 and the motor 204 are waterproofed.

[0033] In this embodiment, since a large amount of disinfectant water is stored inside the disinfection base 1, the two middle and lower parts of the four fixed rods 201 together with the bearings 202 are immersed in the disinfectant water. At the same time, the motor 204 is required to drive the device to operate. Therefore, waterproof treatment is required to prevent the disinfectant water from seeping into the bearings 202 or the motor 204 and causing damage.

[0034] Working principle: put the sample in the sample box 3 at the top, start the two motors 204, the motor 204 drives the bearing 202 through the connecting rod 203, and then drives the conveyor frame 2 to rotate clockwise with the four fixed rods 201 as the axis. The sample box 3 carries the sample into the fluorescence analysis device 4 in the detection partition 103 for allergen detection. After the detection is completed, the conveyor frame 2 changes direction through the fixed rod 201 in the upper right corner, the sample box 3 faces downward, and the sample in the sample box 3 falls into the waste box 105 for recovery by gravity. Then the conveyor frame 2 passes the fixed rod 201 in the lower right corner. After turning, the sample box 3 is turned over and immersed in the disinfectant water in the disinfection base 1. After being disinfected with the disinfectant, it turns through the fixed rod 201 in the lower left corner. The conveying rack 2 drives the sample box 3 to enter the drying component 5. The fan 502 of the drying component 5 blows the air heated by the heating wire 501 to dry the disinfectant, thereby cleaning the sample box 3. Samples can be placed in each sample box 3 and queued up for testing in turn. After being discarded, the samples can be disinfected with disinfectant water and reused to avoid contamination of subsequent sample boxes 3 by the samples, thereby realizing batch inspection of allergens in the samples.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
