[0002] In chemical experiments, hot solutions are commonly used to rinse precipitates. Their core function is to improve washing efficiency and optimize precipitate properties. They can also specifically address the issues of dissolution loss or impurity residue that occur during room-temperature washing. For certain experiments, hot solutions can also effectively remove impurities while reducing the dissolution loss of the precipitate itself, or improve precipitate properties for easier subsequent operations.

[0003] However, manually performing this type of rinsing work while wearing heat-resistant gloves is physically demanding, and inconsistent use of rinsing solution leads to unsatisfactory rinsing results. Furthermore, it poses a risk of burns to lab personnel or the solution having an irritating odor, resulting in occupational health hazards. Utility Model Content

[0026] The heating assembly 7 includes a heating device 701, a heating switch 702, and a temperature knob 703. The heating device 701 is equipped with a heating switch 702 on its front side, and the heating switch 702 is equipped with a temperature knob 703 on one side of its side. The fume hood 1 has ventilation holes on its top, left, rear, and right sides.

[0027] The auxiliary component 6 includes a heating cylinder 601, an upper liquid level sensor 602, and a lower liquid level sensor 603. The upper liquid level sensor 602 is installed on the upper side inside the heating cylinder 601. The lower liquid level sensor 603 is installed below the upper liquid level sensor 602. A high-temperature infusion pipe 9 is installed on one side inside the heating cylinder 601. A liquid pump 8 is installed at one end of the high-temperature infusion pipe 9. A liquid flow meter 10 is installed at the end of the high-temperature infusion pipe 9. A temperature sensor 11 is installed at one end of the liquid flow meter 10 through the high-temperature infusion pipe 9. A nozzle 15 is located below the temperature sensor 11. A rotating frame 12 is installed below the nozzle 15. A filter funnel 13 is arranged in a ring inside the rotating frame 12. A liquid receiving cup 14 is installed at the bottom of the filter funnel 13. A drive component 16 for assisting the rotation of the rotating frame 12 is provided in the middle of the rotating frame 12.

[0028] In practical use, the heating cylinder 601 has a double-layer vacuum design with glass as the inner wall, and the air between the two layers is removed to form a vacuum layer. The rotating frame 12 has a polytetrafluoroethylene (PTFE) surface, and the nozzle 15 has multiple densely packed small holes with a PTFE surface.

[0029] In some embodiments, the drive assembly 16 includes a stepper motor 1601, a frequency tuning knob 1602, a motor switch 1603, and a drive shaft bracket 1604. The output end of the stepper motor 1601 is mounted on the drive shaft bracket 1604. A rotating frame 12 is mounted on the bottom of the drive shaft bracket 1604, and a gear plate 18 is provided on the bottom of the rotating frame 12. A frequency tuning knob 1602 is provided on the front side of the stepper motor 1601, and a motor switch 1603 is mounted on one side of the frequency tuning knob 1602.

[0030] In use, open the fume hood 1, fill the storage bottle 2 with washing solution, adjust the frequency control knob 1602 of the motor according to the number of filter papers to be washed, fold the filter paper and lay it flat in the filter funnel 13, and place the receiving cup 14 under the filter funnel 13 accordingly, turn on the heating switch 702 and the temperature adjustment knob 703 as required, turn on the motor switch 1603, the inlet pump 5 and the outlet pump 8 to start working. The inlet flow meter 4 can detect whether the liquid volume in the storage bottle 2 meets the requirements. The design of the servo motor 21 can drive the stirring rod 22 to rotate, and the stirring rod 22 stirs the liquid in the storage bottle 2 to ensure uniform mixing. The outlet flow meter 10 is used to monitor whether the liquid volume in the heating cylinder 601 meets the requirements. The heated liquid is sprayed into the filter funnel 13 containing the filter paper through the nozzle 15 for washing operation.

[0031] It should be noted that the rinsing time is the same as the set time of the stepper motor 1601. After rinsing, the stepper motor 1601 rotates a certain angle according to the setting to rinse the filter paper in the next filter funnel 13. The temperature sensor 11 is used to monitor whether the temperature of the sprayed liquid meets the requirements. If the temperature is lower than the set temperature, the spraying will stop automatically. After heating for 5 minutes, it will continue to work. When the liquid in the heating cylinder 601 is higher than the upper liquid level sensor 602, the liquid inlet pump 5 stops working and stops delivering washing liquid to the heating cylinder 601. When the liquid in the heating cylinder 601 is lower than the lower liquid level sensor 603, the liquid inlet pump 5 starts working and begins to deliver washing liquid into the heating cylinder 601.

[0032] like Figure 2 and Figure 3 As shown, a base plate 17 is rotatably mounted on the bottom of the toothed disc 18, and the base plate 17 is located inside the fume hood 1. A liquid storage bottle 2 is located on one side of the outside of the fume hood 1, and an outlet 20 is opened on one side of the top of the liquid storage bottle 2. A normal temperature infusion pipe 3 is connected to the top of the normal temperature infusion pipe 3, and an inlet flow meter 4 is installed on the top of the normal temperature infusion pipe 3. An inlet pump 5 is installed on one side of the end of the normal temperature infusion pipe 3. The liquid storage bottle 2 is made of glass, and an inlet 19 is opened on the side of the liquid storage bottle 2 away from the outlet 20. A servo motor 21 is installed in the middle of the liquid storage bottle 2, and a stirring rod 22 is installed at the output end of the servo motor 21. A stirring component 23 for assisting in uniform heating is installed inside the heating cylinder 601.

[0033] In some embodiments, the stirring assembly 23 described above includes a transmission gear 2301, a first roller 2302, a belt 2303, a stirring blade 2304, a stirring shaft 2305, and a second roller 2306. The first roller 2302 is disposed on the top of the transmission gear 2301, and the second roller 2306 is mounted on the first roller 2302 via the belt 2303. The second roller 2306 is disposed on the bottom of the second roller 2306.

[0034] It is understandable that the stepper motor 1601 drives the drive shaft frame 1604 to rotate, which in turn drives the rotating frame 12 connected to the drive shaft frame 1604 to rotate. The rotation of the rotating frame 12 drives the gear disk 18 connected to it to rotate accordingly. The rotation of the gear disk 18 drives the transmission gear 2301 meshing with it to rotate, which in turn drives the roller 2302 connected to the transmission gear 2301 to rotate. With the design of the belt 2303, the stirring shaft 2305 and the roller 2306 can be driven to rotate accordingly. Thus, when heating liquid inside the heating cylinder 601, the rotation of the stirring shaft 2305 inside the cylinder ensures that the heated liquid is mixed evenly and avoids the problem of inconsistent heat.

[0035] In summary, when using this filter paper rinsing device, first open the fume hood 1, fill the storage bottle 2 with washing liquid, adjust the motor frequency adjustment knob 1602 according to the number of filter papers to be rinsed, fold the filter paper flat in the filter funnel 13, place the receiving cup 14 under the filter funnel 13, turn on the heating switch 702 and the temperature adjustment knob 703 as needed, turn on the motor switch 1603, the inlet pump 5 and the outlet pump 8 to start working, the inlet flow meter 4 can detect whether the liquid volume in the storage bottle 2 meets the requirements, the design of the servo motor 21 can drive the stirring rod 22 to rotate, the stirring rod 22 stirs the liquid in the storage bottle 2 to ensure uniform mixing, the outlet flow meter 10 is used to monitor whether the liquid volume in the heating cylinder 601 meets the requirements, the heated liquid is sprayed into the filter funnel 13 containing the filter paper through the nozzle 15 for rinsing; After rinsing, stepper motor 1601 rotates a certain angle according to the set parameters to rinse the filter paper in the next filter funnel 13. Temperature sensor 11 monitors whether the temperature of the sprayed liquid meets the requirements. If the temperature is lower than the set temperature, spraying automatically stops, and the machine continues to work after heating for 5 minutes. When the liquid in heating cylinder 601 is higher than the upper liquid level sensor 602, the inlet pump 5 stops working and stops supplying washing liquid to heating cylinder 601. When the liquid in heating cylinder 601 is lower than the lower liquid level sensor 603, the inlet pump 5 starts working and begins to supply washing liquid into heating cylinder 601. Stepper motor 1601... During operation, the rotating frame 12 connected to the drive shaft frame 1604 can be driven to rotate. The rotation of the rotating frame 12 drives the gear disk 18 connected to it to rotate accordingly. The rotation of the gear disk 18 drives the transmission gear 2301 meshing with it to rotate, thereby driving the roller 2302 connected to the transmission gear 2301 to rotate. With the design of the belt 2303, the stirring shaft 2305 and the roller 2306 can be driven to rotate accordingly. Thus, when heating liquid inside the heating cylinder 601, the rotation of the stirring shaft 2305 inside it can ensure that the heated liquid is mixed evenly and avoid the problem of inconsistent heat.
