Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, and in particular to a low-noise airflow guiding structure for an ultra-clean workbench. Background Technology

[0002] In fields such as biological experiments, precision electronics manufacturing, and pharmaceutical research and development, where stringent requirements for the cleanliness of the operating environment are met, laminar flow hoods, as core local purification equipment, have been widely used. Laminar flow hoods mainly rely on fans to drive air through multi-stage filtration of primary and high-efficiency filters, forming a unidirectional clean airflow in the operating area, thereby isolating external dust, microorganisms, and other contaminants, ensuring the purity of the objects being handled and the safety of the experimental process.

[0003] The airflow channels are mostly designed as single straight cylinders or right-angle bends. When the airflow passes through the bends, it is easy to form eddies. This not only causes airflow turbulence and reduces the airflow uniformity in the clean area, but also generates a lot of aerodynamic noise due to the violent collision between the airflow and the channel wall and the interaction between the eddies. Long-term use will have an adverse effect on the operator's hearing and concentration. Utility Model Content

[0016] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6This utility model provides a low-noise airflow guiding structure technical solution for an ultra-clean workbench: It includes a main body 1, inside which a guide box 2 is installed. Multiple guide plates 3 are rotatably connected to the inner wall of the guide box 2. One end of each guide plate 3 is connected to a connecting ring 4. An electric slide rail A5 is installed on the inner wall of the guide box 2. Two sliders A6 are slidably connected to the electric slide rail A5. A connecting plate 7 is connected to both sliders A6. Multiple connecting posts 8 are installed on the connecting plate 7, with each connecting post 8 located away from the connecting plate. One end of each plate 7 is slidably connected to the inner wall of the connecting ring 4. A static pressure box 9 is installed on the inner wall of the main body 1. A bracket 10 is connected to the inner wall of the static pressure box 9. An ultra-quiet fan 11 is connected to the bracket 10. The static pressure box 9 is connected to the guide box 2. A filter box 12 is connected to the main body 1. Two filter plates 13 are installed inside the filter box 12. The filter box 12 is connected to the static pressure box 9. An air inlet 14 is connected to the filter box 12. A filter screen is installed on the air inlet 14. After the ultra-clean workbench is started, the outside air is first... The air first enters through inlet 14, where a filter screen initially intercepts impurities. The air then enters filter box 12, undergoing multi-stage filtration by two internal filter plates 13 to achieve deep purification of pollutants such as dust and microorganisms. The purified air then enters static pressure box 9, where a stable power source, the ultra-quiet fan 11 on bracket 10, delivers the airflow evenly to the connected guide box 2. At this point, electric slide rail A5 drives two sliders A6 to move synchronously, displacing connecting plate 7 and multiple connecting columns 8. The connecting columns 8, through sliding cooperation with connecting ring 4, pull multiple guide plates 3 on the inner wall of guide box 2 to rotate synchronously, thereby flexibly adjusting the tilt angle of each guide plate to precisely guide the airflow entering the guide box. This ensures that the airflow is delivered to the workbench operating area in a uniform and stable state. The reasonable angle control of the guide plates 3 reduces airflow turbulence, and the ultra-quiet fan 11 further reduces overall operating noise, ultimately achieving a dual technology of clean airflow supply and low-noise operation.

[0018] The main body 1 has a shelf 21 inside, with two grooves 22. Each groove 22 has an electric actuator 23 connected to its inner wall. Each actuator 23 has a mounting block 24 connected to its output end, and a clamping plate 25 connected to each mounting block 24. Each groove 22 has a bellows-style cover 26. The main body 1 also has a lighting lamp 15 and an ultraviolet lamp 16. An electric slide rail B17 is installed inside the main body 1, with a slider B18 slidably connected to it. A connecting rod 19 is connected to the slider B18, and multiple atomizing nozzles 20 are connected to the connecting rod 19. An alcohol storage tank 28 is connected to the outer wall of the main body 1, and a pump body 29 is connected to the alcohol storage tank 28. A delivery pipe 30 is connected to the output end of the pump body 29. The end of the delivery pipe 30 away from the pump body 29 passes through the main body 1 and connects to the connecting rod 19. The shelf 21 holds the object to be processed. For objects of different sizes, the electric actuators in the grooves 22... 23 drives the mounting block 24 to extend and retract, thereby opening and closing the clamping plate 25 to stably clamp the object. The accordion-style cover 26 on the surface of the groove 22 can protect the internal electric push rod 23 and other components from external impurities or disinfectant liquids. When lighting or preliminary sterilization is required, the internal lighting 15 of the main body 1 can be turned on to provide a field of vision, and the ultraviolet lamp 16 can be turned on to achieve basic ultraviolet disinfection. If further alcohol atomization disinfection is required, the alcohol solution in the alcohol storage tank 28 will be transported to the connecting rod 19 through the delivery pipe 30 under the power of the pump body 29, and then formed into a uniform mist of alcohol through multiple atomizing nozzles 20 on it. At the same time, the electric slide rail B17 will drive the slider B18 to slide back and forth, and then drive the atomizing nozzles 20 to move synchronously through the connecting rod 19, so as to achieve all-round, no dead angle alcohol disinfection of the objects inside the main body 1 and on the shelf 21, ensuring the overall disinfection effect.

[0019] The bottom surface of the main body 1 is connected to multiple rollers 27. The outer wall of the main body 1 is connected to a hinge 31 by bolts and threads. The hinge 31 is connected to a door 32 by bolts and threads. The door 32 is equipped with a control panel. The multiple rollers 27 on the bottom surface of the main body 1 provide the whole body with flexible movement capability, and the placement position of the device can be easily adjusted according to the actual use scenario. The hinge 31 connected to the outer wall of the main body 1 by bolts and threads realizes the flexible hinge between the door 32 and the main body 1, which not only ensures the smooth opening and closing of the door 32, but also the control panel integrated on the door 32 serves as the control of the device, which can realize the issuance of commands such as starting and stopping the internal functions of the device and adjusting parameters.

[0020] The working principle of this utility model is as follows: After the equipment is started, the outside air is first initially filtered by the filter screen at the air inlet 14, and then enters the filter box 12 and undergoes deep purification through two filter plates 13. The purified air enters the static pressure box 9, where the ultra-quiet fan 11 on the bracket 10 provides power to transport the airflow to the guide box 2. At this time, the electric slide rail A5 can drive the two sliders A6 and the connecting plate 7 to move. The connecting column 8 on the connecting plate 7 slides on the inner wall of the connecting ring 4, thereby synchronously adjusting the deflection angle of multiple guide plates 3, thus flexibly optimizing the internal flow channel shape of the guide box 2 and avoiding The airflow forms a vortex, allowing it to be blown evenly and smoothly onto the workbench area, creating a stable and clean airflow barrier. Meanwhile, the electric push rod 23 on the placement plate 21 can drive the mounting block 24 and clamping plate 25 to move, achieving a stable clamping of the experimental equipment. The electric slide rail B17 drives the slider B18, connecting rod 19 and atomizing nozzle 20 to move. Together with the alcohol storage tank 28, pump body 29 and delivery pipe 30, alcohol atomization disinfection can be completed inside the workbench. The lighting lamp 15 and ultraviolet lamp 16 provide operating lighting and sterilization protection, respectively. The overall structure achieves low-noise and uniform airflow guidance.

[0021] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
