[0029] 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.

[0030] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a laboratory multifunctional air purification device, including a stirring tank 1, a motor 2 is fixedly connected to the bottom of the stirring tank 1, a rotating shaft 3 is fixedly connected to the output end of the motor 2, a plurality of stirring rods 4 are fixedly connected to the periphery of the rotating shaft 3, a support plate 17 is fixedly connected to the right side of the stirring tank, a vacuum pump 5 is fixedly connected to the top of the support plate 17, an exhaust pipe 6 is fixedly connected to the input end of the vacuum pump 5, an end of the exhaust pipe 6 away from the vacuum pump 5 is fixedly connected to the top of the stirring tank 1, and an exhaust pipe 6 is fixedly connected to the output end of the vacuum pump 5. The air pipe 7 is fixedly connected to the support plate 2 18 on the left side of the stirring tank 1, and the top of the support plate 2 18 is fixedly connected to the collecting box 9, and the right side of the collecting box 9 is fixedly connected to the air intake pipe 8, and the inside of the collecting box is slidably connected to the activated carbon filter 10, and the outside of the collecting box 9 is provided with fixed components on both sides, the top edge of the stirring tank 1 is fixedly connected to the feed port 15, and the bottom of the stirring tank 1 is fixedly connected to four support columns 16, the air intake pipe 8 passes through the stirring tank 1 and is arranged on the inner edge of the stirring tank 1, and the upper and lower ends of the rotating shaft 3 are rotatably connected to the inner wall of the stirring tank 1.

[0031] Specifically, when it is necessary to purify the air in the laboratory, first open the cover of the feed port 15, add an appropriate amount of disinfectant into the stirring tank 1 according to actual needs, and start the motor 2 through an external power supply. As the motor 2 starts, the rotating shaft 3 begins to rotate, thereby driving the stirring rod 4 to rotate, thereby enhancing the mixing effect of the disinfectant and the air, and ensuring that the air can be fully and evenly purified in the disinfectant. In order to further improve the purification effect, the vacuum pump 5 in the device is started. The working principle of the vacuum pump 5 is to suck away the air inside the stirring tank 1 by generating negative pressure. This negative pressure state effectively drives the work of the air intake pipe 8, so that the air in the laboratory is sucked into the disinfectant. When the air enters the disinfectant, fine bubbles are generated and are dispersed by the stirring action of the stirring rod 4. This dispersion process allows the air and the disinfectant to be more fully contacted and mixed, thereby improving the purification effect. At this time, the purified air is extracted and discharged by the vacuum pump 5, reducing the loss of the disinfectant and achieving efficient use of resources.

[0032] Reference Figure 3 and Figure 4The fixing assembly includes a frame 11, the outer side of the frame 11 is fixedly connected to the outer wall of the collecting box 9, a pull rod 12 is slidably connected inside the frame 11, a baffle 13 is fixedly connected to one side of the outside of the pull rod 12, a spring 14 is sleeved on the other side of the outside of the pull rod 12, the baffle 13 is slidably connected to the inside of the frame 11, one end of the spring 14 is fixedly connected to the middle of the baffle 13, and the other end of the spring 14 is fixedly connected to the inner wall of the frame 11, the pull rod 12 passes through the collecting box 9 and is inserted into the inside of the activated carbon filter 10.

[0033] Specifically, the activated carbon filter 10 plays a vital role in the air purification device, which can absorb and remove harmful substances in the air, such as odor, harmful gases and tiny particles. However, long-term use and irregular cleaning may cause impurities such as hair and dust to gradually clog the filter, which not only affects the filtering effect of the filter, but also may have a negative impact on the overall air purification performance. Therefore, regular cleaning of the activated carbon filter 10 is an important step to maintain the stable performance of the air purification device and extend its service life. When the activated carbon filter 10 needs to be cleaned, the user only needs to gently pull the pull rod 12. This action will drive the baffle 13 to move outward and squeeze the spring 14 connected thereto. The design of the spring 14 cleverly balances the movement and reset of the baffle 13, ensuring the smoothness of the operation. With the movement of the baffle, the user can easily take out the activated carbon filter 10 and perform necessary cleaning work. After the cleaning is completed, the user puts the cleaned activated carbon filter 10 back into the collection box 9 and inserts the pull rod 12 into the filter. At this time, the previously compressed spring 14 will gradually restore its original length and push the baffle 13 to make the pull rod 12 tightly inserted into the activated carbon filter 10. This design not only ensures the stable installation of the filter, but also avoids the reduction of the filtering effect caused by the loose filter.

[0034] Working principle: When the laboratory needs to purify the air, first open the cover of the feed port 15, add an appropriate amount of disinfectant into the mixing tank 1, start the motor 2 through an external power supply, rotate the rotating shaft 3 to drive the stirring rod 4 to rotate, start the vacuum pump 5 to suck the air inside the mixing tank 1. At this time, the mixing tank 1 becomes negative pressure, and then drive the air intake pipe 8 to suck the air in the laboratory into the disinfectant. When the air enters the disinfectant, bubbles will be generated, which will be dispersed by the continuous stirring of the stirring rod 4, so that it is fully mixed with the disinfectant to complete the purification of the air. At this time, the purified air is sucked out and discharged through the vacuum pump 5, reducing Regarding the loss of disinfectant, when the activated carbon filter 10 is used for a long time and is not cleaned regularly, impurities such as hair debris are likely to clog the activated carbon filter 10, thereby affecting its filtering effect. Therefore, the activated carbon filter 10 should be cleaned regularly. At this time, pull the pull rod 12 to drive the baffle 13 to move outward to squeeze the spring 14. At this time, the activated carbon filter 10 can be taken out for cleaning. When the cleaning is completed, the activated carbon filter 9 is placed in the collection box 9 and the pull rod 12 is inserted into the activated carbon filter 10. At this time, the spring 14 returns to its original state and pushes the baffle 13 to make the pull rod 12 tightly insert the activated carbon filter 10, thereby completing the installation and disassembly of the activated carbon filter 10.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
