[0001] This utility model relates to the field of medical laboratory equipment technology, specifically to an integrated drying and gas purification machine for glass slide staining. Background Technology

[0002] The integrated drying and gas purification machine for slide staining is a specialized piece of equipment for biomedical laboratories. Its main function is to dry stained slides and purify the gases used in the drying process. This equipment combines the traditionally separate drying and purification steps, shortening slide preparation time, increasing laboratory throughput, and featuring a built-in filtration system to reduce the harm to personnel and environmental pollution caused by volatile toxic substances such as xylene. In the prior art, patent CN 117244330 A discloses an automatic cleaning pulse dust collector, including a dust collection box, an electromagnetic pulse device, a dust detection and suction mechanism, a clamping mechanism, a vibration mechanism, a dehumidification mechanism, a mounting plate, and filter bags. The electromagnetic pulse device is fixedly connected to the left end of the dust collection box, and the dust detection and suction mechanism is electrically connected to the front end of the electromagnetic pulse device. The clamping mechanism is fixedly connected to both the left and right ends of the top of the dust collection box. Although this device can quickly disassemble and install the mounting plate and filter bags by cooperating with the arc-shaped sliding groove on the clamping block using a cylinder, the cylinder seals are prone to wear, leading to cylinder leakage. Cylinder leakage affects the fixing effect of the filter bags, which can cause the filter bags to loosen during operation and affect the filtration quality. Therefore, we propose an integrated drying and gas purification machine for glass slide staining. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This embodiment provides a technical solution: an integrated drying and gas purification machine for glass slide staining, including a body 1, a protective door 3 hinged to the left side of the front end of the body 1, a placement platform 4 provided in the middle of the bottom wall of the body 1, an electric heating wire 5 provided on the upper side inside the body 1, a cavity 13 provided on the lower side inside the body 1, an air inlet 7 provided in the air inlet on the left side of the upper end of the body 1, and an exhaust port 11 provided on the right end of the body 1. The electric heating wire 5 is a nickel-chromium alloy heating wire with high resistivity, which can heat up rapidly after being energized. It also includes a purification mechanism 6.

[0023] Purification mechanism 6 includes a filter chamber 61, a filter element 62, a sealing door 63, and a fixing assembly 64. The filter chamber 61 is located on the right side inside the body 1, and the filter element 62 is placed inside the filter chamber 61. The sealing door 63 is hinged to the upper side of the top wall of the filter chamber 61. The fixing assembly 64 is located inside the filter chamber 61 and is used to fix the filter element 62. The fixing assembly 64 includes a fixing plate 641, a horizontal plate 642, a push plate 643, an adjusting plate 644, a sliding column 645, an adjusting seat 646, a mounting rod 647, and a transmission plate 648. The fixing plate 641 is located on the left side of the bottom wall of the filter chamber 61. Plate 642 is slidably connected to a groove in the middle of the left wall of cavity 13. A push plate 643 is provided at the left end of the horizontal plate 642. The right end of the fixed plate 641 contacts the left end of the filter element 62, and the left end of the push plate 643 contacts the right end of the filter element 62. An adjusting plate 644 is provided at the right end of the horizontal plate 642. A sliding column 645 is provided in a guide groove in the middle of the right end of the adjusting plate 644. An adjusting seat 646 is slidably connected to the rear side of the outer arc surface of the sliding column 645. The adjusting seat 646 is slidably connected to the inner wall of the guide groove. An installation rod 647 is provided on the right side of the bottom wall of the filter chamber 61. The upper side of the outer arc surface of the installation rod 647 rotates. A transmission plate 648 is connected, with its left end rotatably connected to the right end of an adjusting seat 646. During movement, the drive assembly slides within the drive groove and rotates relative to it, causing the drive rod 16 to rotate the transmission plate 648 around the mounting rod 647. As the transmission plate 648 rotates, it exerts a leftward thrust on the adjusting plate 644 via the adjusting seat 646, thus moving the adjusting plate 644 to the left. The adjusting plate 644 then drives the push plate 643 to the left via the cross plate 642. When the left end of the push plate 643 is connected to the right end of the filter element 62... When touched, the push plate 643 will continue to drive the filter element 62 to move to the left. When the distance between the left end of the laser rangefinder 12 and the right end of the push plate 643 is equal to f, it means that the left end of the filter element 62 is in contact with the right end of the fixing plate 641, thereby realizing the limiting and fixing of the filter element 62 (the filter element 82 is an activated carbon filter element, which is mainly made of activated carbon particles or activated carbon fibers and has a high specific surface area and adsorption capacity). The driving method is optimized, the problem of the cylinder affecting the fixing effect of the filter element 62 due to air leakage is solved, the stability of the filter element 62 during purification is improved, and the purification effect of xylene is guaranteed.

[0024] Among them, the front end of the body 1 is equipped with a microcontroller 2. The input end of the microcontroller 2 is electrically connected to an external power supply, and the input end of the electric heating wire 5 is electrically connected to the output end of the microcontroller 2, which can regulate the electrical components inside the device.

[0025] Wherein: an electric push rod 14 is provided on the right side of the front wall of cavity 13, and a slider 15 is slidably connected to the right side of the bottom wall of cavity 13. The rear end of the telescopic end of the electric push rod 14 is fixedly connected to the front end of the slider 15. A drive rod 16 is provided in the middle of the upper end of the slider 15. A drive groove is provided in the middle of the upper end of the transmission plate 648. The upper end of the drive rod 16 is located inside the drive groove. The input end of the electric push rod 14 is electrically connected to the output end of the microcontroller 2. The telescopic end of the electric push rod 14 extends, thereby causing the electric push rod 14 to drive the drive rod 16 to move backward through the slider 15. At this time, the slider 15 will slide and connect with the bottom wall of the filter chamber 61, so the bottom wall of the filter chamber 61 will provide a guide support, reduce the radial force applied by the slider 15 to the electric push rod 14, and prevent the extension end of the electric push rod 14 from bending and deforming (the radial force of the electric push rod 14 is slidably borne by the bottom wall of the filter chamber 61, and the electric push rod 14 is only subjected to the front and rear axial force). During the movement, the drive rod 16 will slide inside the drive groove and rotate relative to the drive groove, so that the drive rod 16 drives the transmission plate 648 to rotate around the mounting rod 647.

[0026] A laser rangefinder 12 is installed on the lower right side of the filter chamber 61. The probe on the left end of the laser rangefinder 12 corresponds to the left and right positions of the push plate 643. The laser rangefinder 12 is bidirectionally electrically connected to the microcontroller 2. During use, the laser emitted by the built-in light source of the laser rangefinder 12 will directly reach the right end of the push plate 643. When the laser comes into contact with the right end of the push plate 643, it will be reflected. Then the laser rangefinder 12 will receive the reflected light. The laser rangefinder 12 calculates the distance between the left end of the laser rangefinder 12 and the right end of the push plate 643 by measuring the round-trip time (TOF) or phase difference of the laser.

[0027] The filter chamber 61 has a conveying port in the middle of the left wall with a conveying pipe 8. The left side of the two conveying pipes 8 is equipped with a fan 9. The input end of the fan 9 is electrically connected to the output end of the microcontroller 2. The fan 9 starts to run through the control of the microcontroller 2. At the same time, the fan 9 will generate suction when it rotates. At this time, the air and xylene inside the body 1 will be discharged into the filter chamber 61 through the conveying pipe 8.

[0028] It also includes an electric valve 10, which is connected in series on the upper side of the two air inlet pipes 7 and the right side of the two delivery pipes 8. The input end of the electric valve 10 is electrically connected to the output end of the microcontroller 2. The electric valve 10 can control the opening and closing of the air inlet pipes 7 and the delivery pipes 8.

[0029] Temperature detectors 17 are installed on the upper and lower sides of the left wall of the filter chamber 61, respectively. The probes of both temperature detectors 17 are located inside the main body 1. Xylene concentration detectors 18 are installed on the upper and lower sides of the left wall of the main body 1 and the upper and lower sides of the rear wall of the filter chamber 61, respectively. Two xylene concentration detectors 18 on the right side are located on the right side of the filter element 62. Both temperature detectors 17 and xylene concentration detectors 18 are bidirectionally electrically connected to the microcontroller 2. The two temperature detectors 17 collect the temperature signal of the precursor solution through a resistance temperature detector (RTD). The RTD converts the temperature change into a change in resistance value. Then, the temperature detectors 17... 7. The resistance value is converted into a temperature value through a built-in algorithm. Then, the temperature detector 17 transmits the calculated data to the microcontroller 2 through the built-in data transmission module. The xylene concentration detector 18 uses ultraviolet light (UV) to irradiate gas molecules, causing them to ionize. When xylene molecules pass through the detector, the energy of the ultraviolet light is sufficient to ionize the xylene molecules, generating positive ions and electrons. These ions and electrons move under the action of an electric field, forming a current signal. The magnitude of the current is proportional to the concentration of xylene. Then, the two sets of xylene concentration detectors 18 on the left transmit the calculated data to the microcontroller 2 through the built-in data transmission module.

[0030] The working principle of the integrated drying and gas purification machine for slide staining provided by this utility model is as follows: Before operation, the sealing door 63 is opened. Then, the operator measures the distance between the right end of the fixed plate 641 and the left end of the push plate 643, the thickness of the push plate 643, and the thickness of the filter element 62 (e.g., a, b, and c). Afterward, the distance between the left end of the laser rangefinder 12 and the right end of the push plate 643 is measured. During use, the laser emitted by the built-in light source of the laser rangefinder 12 directly reaches the right end of the push plate 643. When the laser comes into contact with the right end of the push plate 643, it is reflected. The laser rangefinder 12 then receives the reflected light. By measuring the time to return (TOF) or phase difference of the laser, the laser rangefinder 12 calculates the distance between the left and right ends of the push plate 643. The distance between the left end of the fixed plate 641 and the right end of the push plate 643 is set to d. Then, the laser rangefinder 12 transmits the detected information to the microcontroller 2 through its built-in data transmission module. The microcontroller 2 receives the detected data through its built-in serial communication port. Then, the thickness of the filter element 62 is subtracted from the distance between the right end of the fixed plate 641 and the left end of the push plate 643 to obtain the distance between the filter element 62 and the fixed plate 641 and the push plate 643 (set to e, e=ac). Then, the distance between the left end of the laser rangefinder 12 and the right end of the push plate 643 is added to the thickness of the push plate 63, and then the distance between the filter element 62 and the fixed plate 641 and the push plate 643 is added to obtain the distance between the laser rangefinder 12 and the right end of the push plate 643 when the filter element 62 is fixed. The distance between the left end and the right end of the push plate 643 (e.g., f, f=d+b+e) is then determined. The operator places the filter element 62 at the bottom of the filter chamber 61. Then, controlled by the microcontroller 2, the electric push rod 14 begins to operate. The telescopic end of the electric push rod 14 extends, causing the electric push rod 14 to drive the drive rod 16 backward via the slider 15. At this time, the slider 15 slides against the bottom wall of the filter chamber 61, providing a guiding support and reducing the radial force applied to the electric push rod 14 by the slider 15, preventing the telescopic end of the electric push rod 14 from bending and deforming (the radial force of the electric push rod 14 is borne by the sliding bottom wall of the filter chamber 61; the electric push rod 14 is only subjected to axial force). During the movement of the drive rod 16… The drive rod 16 slides within the drive groove and rotates relative to it, causing the transmission plate 648 to rotate around the mounting rod 647. During this rotation, the transmission plate 648 exerts a leftward thrust on the adjustment plate 644 via the adjustment seat 646, thus moving the adjustment plate 644 to the left. The adjustment plate 644 then moves the push plate 643 to the left via the cross plate 642. When the left end of the push plate 643 contacts the right end of the filter element 62, it continues to move the filter element 62 to the left. When the distance between the left end of the laser rangefinder 12 and the right end of the push plate 643 equals f, it indicates that the left end of the filter element 62 contacts the right end of the fixing plate 641, thereby achieving the limiting and fixing of the filter element 62.Then close the sealing door 63 (the locking method of the door 63 when closed is the common technology of connecting the door lock to the body 1 in the prior art). After that, the operator opens the protective door 3. The operator then places the glass slides to be dried on the upper part of the placement table 4 in sequence. After placement, close the protective door 3 (the locking method of the protective door 3 when closed is the common technology of connecting the door lock to the body 1 in the prior art). Then, through the control of the microcontroller 2, the electric heating wire 5 starts to operate and the electric valve 10 on the right side starts to operate (the electric heating wire 5 is a nickel-chromium alloy heating wire with high resistivity, which can heat up quickly after being energized). The electric valve 10 on the right side opens, and the heat generated by the electric heating wire 5 will raise the temperature inside the body 1. The two sets of temperature detectors 17 are connected by thermoelectric... A resistance sensor is used to collect the temperature signal of the precursor solution. The resistance sensor converts the temperature change into a change in resistance value. Then, the temperature detector 17 converts the resistance value into a temperature value through a built-in algorithm. The temperature detector 17 then transmits the calculated data to the microcontroller 2 through its built-in data transmission module. The microcontroller 2 receives the detected data through its built-in serial communication port. Then, the microcontroller 2 takes an intermediate value based on the data provided by the two temperature detectors 17. This intermediate value is the internal temperature of the body 1. The heating and drying time of the glass slide is usually 15-30 minutes. During the heating and drying process of the glass slide, water and xylene on the outer surface of the glass slide will evaporate. At this time, the two xylene concentration detectors 18 on the left use ultraviolet light (UV) to detect the xylene concentration. The ultraviolet light irradiates the gas molecules, ionizing them. When xylene molecules pass through the detector, the energy is sufficient to ionize them, producing positive ions and electrons. These ions and electrons move under the influence of the electric field, forming a current signal. The magnitude of the current is proportional to the concentration of xylene. Then, the two sets of xylene concentration detectors 18 on the left transmit the calculated data to the microcontroller 2 through the built-in data transmission module. The microcontroller 2 receives the detected data through the built-in serial communication port. Then, the microcontroller 2 takes an intermediate value based on the data provided by the two sets of xylene concentration detectors 18 on the left. This intermediate value is the concentration of xylene inside the machine body 1. When the concentration of xylene is higher than the set value, the fan 9 and the electric valve on the left are activated through the control of the microcontroller 2. When the machine starts operating, the electric valve 10 on the left opens, and at the same time, the fan 9 rotates, generating suction. At this time, the air and xylene inside the machine body 1 are discharged into the filter chamber 61 through the delivery pipe 8. The xylene is then filtered and purified by the filter element 82 (filter element 82 is an activated carbon filter element, mainly made of activated carbon particles or activated carbon fibers, with high specific surface area and adsorption capacity). The purified air is finally discharged through the exhaust port 11. Simultaneously, external air enters the machine body 1 through the air inlet pipe 7, and the electric heating wire 5 heats the air entering the machine body 1, thus continuing to heat and dry the glass slide. The two sets of xylene concentration detectors 18 on the right side will detect the purified air.When the xylene concentration in the purified air exceeds the set value, it indicates a decrease in the filtration efficiency of filter element 62. During subsequent replacement of filter element 62, the sealing door 63 is opened, and the electric push rod 14 starts operating under the control of the microcontroller 2. The telescopic end of the electric push rod 14 extends, causing it to drive the drive rod 16 forward via the slider 15. At this time, the slider 15 slides against the bottom wall of the filter chamber 61, providing a guiding support and reducing the radial force applied to the electric push rod 14 by the slider 15, thus preventing the telescopic end of the electric push rod 14 from bending or deforming (the radial force of the electric push rod 14...). The force is borne by the sliding of the bottom wall of the filter chamber 61 (the electric push rod 14 is only subjected to the front and rear axial force). During the movement, the drive rod 16 slides inside the drive groove and rotates relative to the drive groove, thereby causing the drive rod 16 to drive the transmission plate 648 to rotate around the mounting rod 647. During the rotation of the transmission plate 648, the transmission plate 648 will exert a rightward pulling force on the adjusting plate 644 through the adjusting seat 646, thereby causing the adjusting plate 644 to move to the right. The adjusting plate 644 will then drive the push plate 643 to move to the right and reset through the horizontal plate 642, thereby separating the push plate 643 from the filter element 62, and then the filter element 62 can be replaced.

[0031] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be AT89C51, the fan 9 can be ME92252V1-000C-A99, the electric valve 10 can be Q965F-16C, the laser rangefinder 12 can be HMLDM-UD100A, the electric actuator 14 can be DYTFD2000-550 / 45, the temperature detector 17 can be OHR-E700, and the xylene concentration detector 18 can be PGM-7340.
