Description
Technical Field
[0001] This invention belongs to the field of analyzer technology, specifically relating to a handheld fluorescence immunoassay analyzer with dustproof function. Background Technology
[0002] Handheld fluorescence immunoassay analyzers, with their small size and portability, have been widely used in many fields such as food safety testing, outdoor rescue, and home medical care, providing great convenience for testing personnel and enabling them to conduct testing anytime, anywhere. However, in actual use, because the test paper slot is always open whether in use or not, dust and dirt can easily enter the analyzer. Once this dust and dirt accumulates on the optical components, it reduces the detection efficiency of the fluorescence signal, obstructs the field of view during testing, and thus seriously affects the accuracy of the test results. Summary of the Invention
[0003] (1) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, the present invention aims to provide a handheld fluorescence immunoassay analyzer with dustproof function. This analyzer is designed to solve the problem that existing handheld fluorescence immunoassay analyzers are prone to dust and dirt entering through the test paper insertion holes, affecting the accuracy of test results.
[0005] (2) Technical solution
[0006] To address the aforementioned technical problems, this invention provides a handheld fluorescence immunoassay analyzer with dustproof functionality. The analyzer includes an analyzer body and a test paper insertion hole at one end of the analyzer body. A dustproof component is located at the end of the test paper insertion hole near the outer side of the analyzer body. The dustproof component includes a dustproof plate, a driving component, and a toggle component. The dustproof plate can be elastically raised and lowered within the test paper insertion hole. An installation cavity is formed inside the analyzer body at the end near the test paper insertion hole. The driving component and the toggle component are rotatably installed within the installation cavity. One side of the toggle component is located outside the analyzer body. Rotating the toggle component drives the driving component to open the test paper insertion hole from the dustproof plate.
[0007] Preferably, the dustproof plate includes an L-shaped baffle, with shielding plates fixedly connected to both the left and right sides of the L-shaped baffle. A fixing rod is fixedly connected to the other end of the shielding plate, and a ball is fixedly connected to the other end of the fixing rod. Two fixing seats are fixedly connected to the top of the inner wall of the front of the analyzer body. Two sliding rods are fixedly connected to the upper surface of the L-shaped baffle. A spring is sleeved on the outer surface of the top of the sliding rod and passes through the fixing seat. The sliding rod is slidably connected to the fixing seat.
[0008] Furthermore, a sponge pad is fixedly connected to the lower surface of the L-shaped baffle, and clearance grooves communicating with the mounting cavity are opened on both the left and right sides of the test paper insertion hole, with the baffle located in the clearance groove.
[0009] Furthermore, the driving component includes a disc, a gear, a first rotating shaft, and a torsion spring. The disc and the gear are fixedly connected to the upper and lower sides of the outer surface of the first rotating shaft, respectively. The bottom end of the first rotating shaft is rotatably connected to the inner wall of the mounting cavity through a bearing. The torsion spring is sleeved and installed on the inner bottom of the first rotating shaft. An arc-shaped top plate corresponding to the sphere is fixedly connected to the edge of the upper surface of the disc. The upper surface of the arc-shaped top plate gradually increases from the sphere.
[0010] Furthermore, a first limiting block is fixedly connected to the outer surface of the disc, and a second limiting block is fixedly connected to the top of the arc-shaped top plate.
[0011] Furthermore, the actuating component includes a dial and a second rotating shaft. The dial is fixedly connected to the outer surface of the second rotating shaft. The bottom end of the second rotating shaft is rotatably connected to the inner wall of the mounting cavity through a bearing. The end of the dial located inside the mounting cavity is fixedly connected with multiple tooth grooves, which mesh with gears. The end of the dial located outside the analyzer body is provided with anti-slip textures. The analyzer body is provided with clearance holes corresponding to the dial.
[0012] Furthermore, there are two driving components, two actuating components, and two mounting cavities, located on the left and right sides of the analyzer body, respectively.
[0013] Furthermore, the analyzer body includes an upper housing and a lower housing. The upper housing is equipped with buttons and a display screen. Inside the analyzer body, above the test paper insertion hole, are the detection board and the main control board.
[0014] (3) Beneficial effects
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0016] This invention features a dustproof component at the end of the test paper slot near the analyzer body. During use, rotating the actuating element opens the test paper slot by rotating the driving element, allowing the test paper to be inserted without the need for fingers to touch the dustproof element, ensuring smooth and accurate insertion. After testing, the spring's restoring force returns the dustproof element to its original position, closing the test paper slot. This effectively prevents dust from entering the analyzer during and after testing, ensuring the cleanliness of the internal optical components and improving the accuracy of the fluorescence immunoassay analyzer's results.

[0027] This specific embodiment is a handheld fluorescence immunoassay analyzer with dustproof function, and its structural schematic diagram is shown below. Figures 1-7As shown, the analyzer includes an analyzer body 1 and a test paper insertion hole 2 at one end of the analyzer body 1. A dustproof component 3 is provided at the end of the test paper insertion hole 2 near the outside of the analyzer body 1. The dustproof component 3 includes a dustproof plate 4, a driving component 5, and a toggle component 6. The dustproof plate 4 can be elastically raised and lowered within the test paper insertion hole 2. A mounting cavity 7 is provided inside the end of the analyzer body 1 near the test paper insertion hole 2. The driving component 5 and the toggle component 6 are rotatably mounted in the mounting cavity 7. One side of the toggle component 6 is located on the analyzer body 1. Externally, rotating the toggle 6 drives the drive 5 to open the dustproof plate 4 and test paper insertion hole 2. The analyzer body 1 includes an upper housing 101 and a lower housing 102. The upper housing 101 is equipped with a button 103 and a display screen 104. Inside the analyzer body 1 and above the test paper insertion hole 2, a detection board 105 and a main control board 106 are installed. The button 103 enables the detection board 105 and the main control board 106 to detect the inserted test paper and display the results on the display screen 104.
[0028] The handheld fluorescence immunoassay analyzer's detection board 105 and main control board 106 can read and analyze common pet disease detection reagents. It also features an AI health engine on the software side, which uses machine learning and deep learning algorithms to intelligently assess the pet's health status. After obtaining the test results calculated by the main control board 106, the AI health engine will comprehensively evaluate various factors, such as the pet's breed, age, gender, and historical test data, to determine the pet's health status and provide corresponding health tips, offering highly valuable diagnostic advice to doctors.
[0029] Supervised learning in machine learning algorithms builds data models using a large amount of labeled pet health data, such as test data samples of healthy and sick pets. These data samples cover test indicators of pets of different breeds, ages, and genders in various common disease states, including blood routine, biochemical indicators, infectious disease test results, etc.
[0030] Deep learning algorithms further enhance the intelligence level of AI health engines. For example, deep neural networks (DNNs) contain multiple hidden layers and can automatically extract deep features from a large amount of detection data. These deep learning algorithms can continuously optimize model parameters and improve the accuracy and reliability of judging the health status of pets.
[0031] like Figure 6 and Figure 7As shown: In this embodiment, the dustproof plate 4 includes an L-shaped baffle 401. A shielding plate 402 is fixedly connected to both the left and right sides of the L-shaped baffle 401. The left and right sides of the L-shaped baffle 401 contact the inner walls of the left and right sides of the test paper insertion hole 2. The shielding plate 402 contacts the inner wall of the front of the lower housing 102, ensuring there are no gaps around the L-shaped baffle 401. A fixing rod 403 is fixedly connected to the other end of the shielding plate 402. A ball 404 is fixedly connected to the other end of the fixing rod 403. Two fixing seats 405 are fixedly connected to the top of the inner wall of the front of the analyzer body 1. Two sliding rods 406 are fixedly connected to the upper surface of the L-shaped baffle 401. A spring 407 is sleeved on the outer surface of the top of the sliding rod 406 and passes through the fixing seat 405. The sliding rod 406 is slidably connected to the fixing seat 405. In this way, the L-shaped baffle 401 can drive the sliding rod 406 to slide up and down along the fixing seat 405 and compress the spring 407, making opening and closing smoother.
[0032] like Figure 7 and Figure 9 As shown: In this embodiment, a sponge pad 408 is fixedly connected to the lower surface of the L-shaped baffle 401, and clearance grooves 409 communicating with the mounting cavity 7 are provided on both the left and right sides of the test paper insertion hole 2. The baffle 402 is located in the clearance grooves 409. The sponge pad 408 can increase the sealing with the bottom and reduce the local pressure when in contact with the test paper, so as to better perform the test.
[0033] like Figure 6 , Figure 7 and Figure 9As shown: In this embodiment, the driving component 5 includes a disc 501, a gear 502, a first rotating shaft 503, and a torsion spring 504. The disc 501 and gear 502 are respectively fixedly connected to the upper and lower sides of the outer surface of the first rotating shaft 503. The bottom end of the first rotating shaft 503 is rotatably connected to the inner wall of the mounting cavity 7 through a bearing. The torsion spring 504 is sleeved and installed on the inner bottom of the first rotating shaft 503. An arc-shaped top plate 505 corresponding to the sphere 404 is fixedly connected to the edge of the upper surface of the disc 501. The upper surface of the arc-shaped top plate 505 gradually increases from the sphere 404. The actuating component 6 includes a dial 601 and a second rotating shaft 602. The dial 601 is fixedly connected to the outer surface of the second rotating shaft 602. The bottom end of the second rotating shaft 602 is rotatably connected to the inner wall of the mounting cavity 7 through a bearing. A plurality of toothed grooves 603 are fixedly connected to one end of the dial 601 located inside the mounting cavity 7. The toothed groove 603 meshes with the gear 502. The dial 601 has anti-slip texture on one end outside the analyzer body 1. The analyzer body 1 has a clearance hole 604 corresponding to the dial 601. By rotating one side of the dial 601, the dial 601 rotates away from the dustproof plate 4. At the same time, the toothed groove 603 on one side of the dial 601 causes the gear 502, the first rotating shaft 503, the disc 501 and the arc-shaped top plate 505 to rotate and compress the torsion spring 504. Since the ball 404 on one side of the L-shaped baffle 401 is located at the lower part of the arc-shaped top plate 505, the higher part of the arc-shaped top plate 505 will gradually squeeze the ball 404 during the rotation. This causes the fixed rod 403, the baffle 402, the L-shaped baffle 401 and the slide rod 406 to move upward and compress the spring 407. During the movement, the L-shaped baffle 401 can open the test paper insertion hole 2.
[0034] like Figure 6 and Figure 7 As shown: In this embodiment, a first limiting block 506 is fixedly connected to the outer surface of the disc 501, and a second limiting block 507 is fixedly connected to the top of the arc-shaped top plate 505. The first limiting block 506 restricts the reset of the disc 501, so that the ball 404 is located at the lowest point of the arc-shaped top plate 505. The second limiting block 507 restricts the rotation of the actuating member 6, so that the actuating member 6 can better open the dustproof plate 4 and prevent the ball 404 from falling off the arc-shaped top plate 505.
[0035] To facilitate opening the dust cover 4 with both the left and right hands, such as Figure 1 and Figure 6 As shown: In this embodiment, there are two driving components 5, two toggle components 6, and two mounting cavities 7, which are located on the left and right sides of the analyzer body 1, respectively.
[0036] Working principle: When in use, hold the analyzer body 1 and use your thumb to rotate the dial 601 on one side. At this time, the dial 601 rotates away from the dustproof plate 4. Simultaneously, the toothed groove 603 on one side of the dial 601 causes the gear 502, the first rotating shaft 503, the disc 501, and the arc-shaped top plate 505 to rotate and compress the torsion spring 504. Since the ball 404 on one side of the L-shaped baffle 401 is located at the lower part of the arc-shaped top plate 505, the higher part of the arc-shaped top plate 505 will gradually squeeze the ball 404 during the rotation, causing the fixing rod 403 and the baffle to... Plate 402, L-shaped baffle 401 and slide bar 406 move upward and compress spring 407. During the movement, L-shaped baffle 401 can open test paper insertion hole 2. Then, the other hand inserts the test paper into test paper insertion hole 2. Then, the dial 601 is released. At this time, the restoring force of torsion spring 504 makes disc 501 return to its original position, and the restoring force of spring 407 makes L-shaped baffle 401 return to its original position. Then, the detection board 105 and main control board 106 detect the inserted test paper by pressing button 103 and display the result on display screen 104.
[0037] All technical features in this embodiment can be freely combined according to actual needs.
[0038] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
