[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Reference Figs. 1-3 A smear applicator for testing includes a main body 1, a fixing mechanism, and a scraping mechanism. The main body 1 is provided with feet 16. The fixing mechanism includes a fixing block 11 and a pushing block 12. The scraping mechanism includes a mounting frame 3, a mounting base 2, and a glass slide 13. The mounting frame 3 is provided with a second motor 31, a micro air pump 33, a sample storage box 34, and a dispensing head 35. The mounting base 2 is provided with a first motor 21, a rotating shaft 24, and a slider 22. The slider 22 is provided with a scraper 23. The feet 16 are located on the main body 1. At the four corners of the lower surface, the fixing block 11 and the push block 12 are located on the upper surface of the main body 1, the mounting bracket 3 and the mounting base 2 are located on the upper surface of the main body 1, the second motor 31, the micro air pump 33 and the sample storage box 34 are mounted on the mounting bracket 3, the applicator head 35 is located below the sample storage box 34, the first motor 21 and the rotating shaft 24 are mounted on the mounting base 2, the slider 22 is threadedly connected to the rotating shaft 24, and the scraper 23 is fixedly connected to the slider 22.
[0019] The feet 16 at the four corners of the lower surface of the main body 1 provide stable support for the smear applicator, keeping it stable on the worktable. The fixing block 11 and the push block 12 in the fixing mechanism are located on the upper surface of the main body 1. The two work together to firmly fix the glass slide 13, preventing displacement during the smearing process and ensuring the accuracy of the smear. In terms of the smearing mechanism, the second motor 31 on the mounting frame 3 drives the connected rotating shaft 311 to rotate, thereby moving the mounting frame 3 up and down to facilitate the sample drop operation; the micro air pump 33 is installed on the mounting frame 3 to provide air pressure to the sample storage box 34, causing the sample to drop onto the glass slide 13 through the smearing head 35; the sample storage box 34 is located above the smearing head 35 and is used to store the sample and facilitate its delivery to the smearing head 35; the first motor 21, the rotating shaft 24 and the slider 22 on the mounting base 2 work together to drive the slider 22 to move, which in turn drives the scraper 23 to perform the smearing operation.
[0020] The fixing block 11 has positioning blocks 111 on both sides, and the main body 1 has a sliding groove 14, in which the push block 12 slides.
[0021] Positioning blocks 111 are located on both sides of fixing blocks 11, and their function is to position the slide 13. The sliding groove 14 on the main body 1 provides a sliding track for the push block 12. The push block 12 slides in the sliding groove 14 and contacts the slide 13 through the positioning blocks 111, so that the slide 13 can be accurately positioned in a specific position during the fixing process. This ensures that the slide 13 is accurately positioned during the coating operation and provides a guarantee for the smooth progress of subsequent coating work.
[0022] A spring 15 is provided on the rear side wall of the push block 12, and the other end of the spring 15 is connected to the side wall of the slide groove 14.
[0023] When the push block 12 and the fixing block 11 are used to fix the glass slide 13, the spring 15 will be compressed or stretched due to the sliding of the push block 12. The resulting elastic force can make the push block 12 fit the glass slide 13 better, enhance the fixing effect of the glass slide 13, ensure its stability during the coating process, and reduce the possibility of displacement.
[0024] The mounting base 2 is provided with a first positioning rod 25, the output end of the first motor 21 is connected to the rotating shaft 24, and the slider 22 is slidably connected to the first positioning rod 25.
[0025] The first positioning rod 25 on the mounting base 2 serves a positioning and guiding function. The first motor 21, acting as a power source, has its output end connected to the rotating shaft 24. When the first motor 21 rotates, it drives the rotating shaft 24 to rotate synchronously, thus providing power for subsequent mechanical movements. The slider 22 is slidably connected to the first positioning rod 25, allowing the slider 22 to slide along the length of the first positioning rod 25. This restricts the movement trajectory of the slider 22, ensuring it can only move in a straight line along the first positioning rod 25. This guarantees the accuracy and stability of the slider 22's movement and also makes the relative positional relationship between the slider 22 and other components clearer and more controllable, ensuring the coordinated operation of the entire device.
[0026] The mounting bracket 3 is provided with a second positioning rod 312 and a rotating shaft 311. The rotating shaft 311 passes through the mounting bracket 3 and is connected to the second motor 31. The mounting bracket 3 is provided with a mounting plate 32. The mounting plate 32 is provided with a threaded hole 321 and a positioning hole 322. The rotating shaft 311 passes through the threaded hole 321 and is threadedly connected to the mounting plate 32. The second positioning rod 312 passes through the positioning hole 322 and is slidably connected to the mounting plate 32.
[0027] The mounting bracket 3 is equipped with a second positioning rod 312 and a rotating shaft 311. The rotating shaft 311 passes through the mounting bracket 3 and is connected to a second motor 31. When the second motor 31 starts running, it drives the rotating shaft 311 to rotate. The mounting bracket 3 is also equipped with a mounting plate 32, which has a threaded hole 321 and a positioning hole 322. The rotating shaft 311 passes through the threaded hole 321 and forms a threaded connection with the mounting plate 32. Due to the characteristics of the thread, the rotating shaft 311 will produce a linear displacement along its axial direction when it rotates. The second positioning rod 312 passes through the positioning hole 322 and is slidably connected to the mounting plate 32. Its main function is to position and guide the mounting plate 32. When the mounting plate 32 is subjected to the force of the rotating shaft 311 or other factors that cause it to move, the second positioning rod 312 will ensure that the mounting plate 32 slides smoothly along its axial direction, restricting the mounting plate 32 to move only along the direction of the second positioning rod 312, and preventing the mounting plate 32 from deviating or shaking in other directions, thereby ensuring the stability and accuracy of the movement of the mounting plate 32, and ensuring the stable operation and normal functioning of the entire coating mechanism.
[0028] The micro air pump 33 and the sample storage box 34 are mounted on the mounting plate 32. The micro air pump 33 is provided with an air inlet 331 on the top, and the sample storage box 34 is provided with a protective cover 341 on the top. The sample storage box 34 is connected to the applicator head 35, and the micro air pump 33 is connected to the sample storage box 34.
[0029] The miniature air pump 33 has an air inlet 331 on its top. The miniature air pump 33 is connected to the sample storage box 34 and can supply gas to the sample storage box 34, propelling the sample inside to perform corresponding actions. The sample storage box 34 is equipped with a protective cover 341 on its top, which prevents the sample from being contaminated by external factors and facilitates sample addition or maintenance operations. The sample storage box 34 is connected to the applicator 35, and the sample stored in the sample storage box 34 can flow to the applicator 35 through the connecting channel.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
