Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and in particular to an energy-saving dual-person operation purification workbench. Background Technology

[0002] Currently, clean benches are widely used in laboratory and medical environments where aseptic operation is critical. Traditional two-person clean benches typically employ a fixed design, resulting in high energy consumption from their fans and filtration systems, which significantly increases energy costs over extended periods. Furthermore, existing two-person clean benches often feature a single-zone air supply structure, leading to uneven airflow distribution within the operating area and impacting purification efficiency. In practical use, the lack of flexible energy-saving control methods often results in the equipment operating at full power, making energy optimization difficult even under low load conditions. Additionally, traditional clean bench designs rarely consider the rational allocation of space for two-person operation, potentially causing inconvenience or interference and ultimately reducing work efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide an energy-saving dual-person operation clean bench, which solves the problems mentioned in the background art.

[0004] This utility model is implemented as follows: an energy-saving dual-person operation purification workbench. The workbench mainly consists of a workbench body, an air supply module located at the top of the workbench body, a zoned airflow regulating mechanism located inside the workbench body, and operation panels installed on both sides of the workbench body. The air supply module includes a fan and a high-efficiency filter. The fan is fixed to the frame at the top of the workbench body with bolts. The high-efficiency filter is connected to the air guide channel below the fan via a snap-fit ​​structure. The bottom of the air guide channel has evenly distributed air outlets for delivering filtered clean air into the operating area. The zoned airflow regulating mechanism includes two independent guide plate assemblies. Each guide plate assembly consists of multiple adjustable-angle guide plates. The guide plates are connected to a support frame inside the workbench body via a rotating shaft. One end of the rotating shaft extends outward from the workbench body and is connected to a manual knob for adjusting the angle of the guide plates according to actual needs, thereby achieving precise control of the airflow direction.

[0005] The control panels are located on the left and right sides of the platform, each with an independent control unit. These control units are connected to the fan and the zoned airflow regulation mechanism via wires. The control units include a touchscreen and physical buttons. The touchscreen displays the current operating status and parameter settings, while the physical buttons are used for quickly switching between different operating modes. The platform has four height-adjustable feet at the bottom, connected to mounting holes on the bottom of the platform via threads. The bottom of the feet has anti-slip rubber pads to enhance stability. A transparent baffle is located on the front of the platform, connected to the platform via a slide rail. Positioning pins at both ends of the slide rail are used to fix the position of the transparent baffle and prevent it from moving during use.

[0006] The platform also houses an energy consumption monitoring module, which is connected to the fan and HEPA filter via sensors. The sensors collect real-time data on the fan's operating power and the HEPA filter's resistance, transmitting the data to the control unit for analysis. The control unit automatically adjusts the fan speed based on the collected data. When no personnel activity is detected in the operating area, the fan speed automatically decreases to a preset low-power mode, thereby reducing energy consumption. Furthermore, an exhaust duct is located at the rear of the platform, connected to an external exhaust system via a flange. An adjustable damper is located at the duct's inlet, connected to a handle on the outside of the platform via a linkage. The handle's rotation angle is proportional to the damper's opening, used to adjust the exhaust volume.

[0007] The zoned airflow regulation mechanism ensures a more uniform airflow distribution within the operating area, avoiding the problems of excessively strong or weak localized airflow caused by traditional single-zone air supply structures. The angle of the baffles can be flexibly adjusted according to the needs of different experiments or operations, thereby optimizing the airflow path and improving the purification effect. Simultaneously, two independent control panels provide convenience for dual-person operation; each operator can independently set the working mode according to their needs without interference, significantly improving work efficiency.

[0008] The beneficial effects of this utility model are as follows: the airflow distribution within the operating area is achieved through the zoned airflow adjustment mechanism, solving the problem of uneven airflow distribution in traditional clean benches; the energy consumption is significantly reduced through the energy consumption monitoring module and automatic adjustment function, especially under low load conditions, which can effectively save energy; the independent operation panel design rationally allocates space for two-person operation, reducing mutual interference during operation; the overall structure is compact, easy to install and maintain, and suitable for widespread application in laboratory and medical environments.

[0014] This utility model relates to an energy-saving dual-person operation cleanroom workbench, the overall structure of which is as follows: Figure 1 As shown, the device includes a platform 1, an air supply module 2, a zoned airflow adjustment mechanism 3, an operation panel 4, support legs 11, a transparent baffle 12, an exhaust duct 13, an air damper 14, a handle 15, and an energy consumption monitoring module 16. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] The platform 1 forms the main frame of the entire clean bench, made of stainless steel, offering excellent corrosion resistance and structural strength. An air supply module 2, consisting of a fan 5 and a high-efficiency particulate air (HEPA) filter 6, is mounted on the top of platform 1. The fan 5 is bolted to the top frame of platform 1, with its inlet connected to external air and its outlet connected to the HEPA filter 6. The HEPA filter 6 is secured to the air guide channel below the fan 5 using a snap-fit ​​mechanism. The bottom of the air guide channel has evenly distributed air outlets to deliver filtered clean air into the operating area. The design of the air guide channel ensures even air distribution throughout the operating area, preventing localized areas of excessively strong or weak airflow.

[0016] The zoned airflow regulation mechanism 3 is located inside the platform 1, and its specific structure is as follows: Figure 2As shown. The zoned airflow regulating mechanism 3 includes two independent guide vane assemblies, each consisting of multiple guide vanes 7. The guide vanes 7 are connected to a support frame inside the platform 1 via a rotating shaft. One end of the rotating shaft extends outward from the platform 1 and is connected to a manual knob 8. The manual knobs 8 are located on both sides of the platform 1, allowing operators to easily adjust the angle of the guide vanes 7 according to actual needs. The angle adjustment range of the guide vanes 7 is 0° to 90°. By manually rotating the knob 8, the rotating shaft is turned, thereby changing the tilt angle of the guide vanes 7 and achieving precise control of the airflow direction. The surface of the guide vanes 7 undergoes special treatment, resulting in low air resistance and ensuring smooth airflow.

[0017] The control panels 4 are located on the left and right sides of the platform 1, respectively, each with an independent control unit. The control unit includes a touchscreen 9 and physical buttons 10. The touchscreen 9 displays the current operating status and parameter settings, such as the fan speed 5, the resistance value of the high-efficiency filter 6, and data collected by the energy consumption monitoring module 16. The physical buttons 10 are used to quickly switch between different operating modes, such as high-speed mode, low-speed mode, and automatic mode. The control unit is connected to the fan 5 and the zoned airflow adjustment mechanism 3 via wires, allowing operators to control the equipment in real time via the touchscreen 9 or the physical buttons 10. The layout of the touchscreen 9 and physical buttons 10 is optimized to ensure convenient operation and prevent accidental touches.

[0018] The bottom of the platform 1 has four height-adjustable legs 11, which are threaded to mounting holes on the bottom of the platform 1. The height adjustment range of the legs 11 is 0 to 50 mm. The height of the platform 1 can be adjusted by rotating the legs 11 to adapt to different usage scenarios. The bottom of the legs 11 is equipped with anti-slip rubber pads, which effectively prevent the equipment from sliding when in contact with the ground, enhancing the stability of the equipment. The front of the platform 1 has a transparent baffle 12, which is connected to the platform 1 via a slide rail. The two ends of the slide rail are equipped with positioning pins to fix the position of the transparent baffle 12. The transparent baffle 12 can slide freely on the slide rail and is locked in the closed or open position by the positioning pins to prevent it from moving during use.

[0019] An exhaust duct 13 is located on the rear side of the platform 1, and the exhaust duct 13 is connected to an external exhaust system via a flange. An air damper 14 is located at the inlet of the exhaust duct 13, and the air damper 14 is connected to a handle 15 on the outside of the platform 1 via a connecting rod. The rotation angle of the handle 15 is proportional to the opening degree of the air damper 14. By rotating the handle 15, the opening degree of the air damper 14 can be adjusted, thereby controlling the exhaust volume. The design of the air damper 14 allows the operator to flexibly adjust the exhaust volume according to experimental needs, ensuring airflow balance within the operating area.

[0020] The platform 1 also houses an energy consumption monitoring module 16, which is connected to the fan 5 and the high-efficiency filter 6 via sensors. The sensors collect real-time data on the operating power of the fan 5 and the resistance of the high-efficiency filter 6, transmitting the data to the control unit for analysis. When the energy consumption monitoring module 16 detects no personnel activity in the operating area, the control unit automatically reduces the fan 5's speed to a preset low-power mode, thereby reducing energy consumption. Furthermore, the control unit can determine whether the high-efficiency filter 6 needs replacement based on changes in its resistance and prompt the operator for maintenance via the touchscreen 9.

[0021] In practical applications, the operation process of this utility model is as follows: First, adjust the height of the support legs 11 to keep the platform 1 level, then slide the transparent baffle 12 to the closed state and fix it with the positioning pin. The operator rotates the manual knob 8 to adjust the angle of the guide plate 7 according to experimental needs to optimize the airflow path. Then, start the equipment via the touchscreen 9 or physical buttons 10 on the operation panel 4 and select the appropriate working mode. The fan 5 starts running, and external air, filtered by the high-efficiency filter 6, is evenly delivered to the operating area through the air guide duct. During this process, the energy consumption monitoring module 16 collects the operating power of the fan 5 and the resistance data of the high-efficiency filter 6 in real time and transmits the data to the control unit for analysis. If no personnel activity is detected in the operating area, the control unit will automatically reduce the speed of the fan 5 to save energy. Simultaneously, the operator can adjust the opening of the damper 14 by rotating the handle 15 to meet the exhaust requirements under different experimental conditions.

[0022] This invention achieves uniform airflow distribution within the operating area through the aforementioned structural design, solving the problem of uneven airflow distribution in traditional clean benches. The zoned airflow adjustment mechanism 3 allows for flexible adjustment of the airflow path according to experimental needs, improving purification efficiency. The independent control panel 4 facilitates dual-person operation; each operator can independently set their working mode without interference. The overall structure is compact, easy to install and maintain, and suitable for widespread application in laboratory and medical environments.

[0023] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0024] First, during equipment installation, the operator must adjust the height of the support legs 11 to keep the platform 1 level. The support legs 11 are threaded into mounting holes on the bottom of the platform 1; rotating the support legs 11 adjusts their height, with an adjustment range of 0 to 50 mm. The anti-slip rubber pads on the bottom of the support legs 11 effectively prevent slippage during use, ensuring equipment stability. After leveling, the transparent baffle 12 is slid along the slide rail to the closed position and fixed in place by the positioning pins at both ends of the slide rail, forming a sealed operating area to prevent external contaminants from entering.

[0025] Subsequently, the operator manually adjusted the angle of the guide vane 7 in the zoned airflow regulating mechanism 3 according to the experimental requirements. For example... Figure 2 As shown, the baffle 7 is connected to the support frame inside the platform 1 via a rotating shaft. One end of the rotating shaft extends outward from the platform 1 and is connected to the manual knob 8. The operator can rotate the manual knob 8 to drive the rotating shaft, thereby changing the tilt angle of the baffle 7. The angle adjustment range of the baffle 7 is 0° to 90°. By precisely controlling the angle of the baffle 7, the airflow path can be optimized, making the clean air more evenly distributed in the operating area. The surface of the baffle 7 is specially treated to have low air resistance, ensuring smooth airflow and avoiding a decrease in purification effect due to airflow turbulence.

[0026] When the equipment starts, fan 5 begins operation, and outside air, filtered by HEPA filter 6, is evenly delivered to the operating area through air guide channels. The bottom of the air guide channels has evenly distributed air outlets, ensuring that the filtered clean air covers the entire operating area and preventing localized areas from being too strong or too weak. At this time, operators can view the real-time operating status of fan 5, the resistance value of HEPA filter 6, and data collected by energy consumption monitoring module 16 via touchscreen 9. If there is no personnel activity in the operating area, energy consumption monitoring module 16 will detect relevant signals and automatically reduce the speed of fan 5 to a preset low-power mode via the control unit, thereby reducing energy consumption. Furthermore, when the resistance value of HEPA filter 6 exceeds a preset threshold, the control unit will prompt the operator via touchscreen 9 to perform maintenance or replacement, ensuring the equipment is always in optimal operating condition.

[0027] In practice, when two people use the clean bench simultaneously, each can independently operate the control panels 4 on their left and right sides. Each control panel 4 has an independent control unit, including a touch screen 9 and physical buttons 10. The touch screen 9 displays the current working status and parameter settings, such as the speed of the fan 5 and the resistance value of the HEPA filter 6; the physical buttons 10 are used to quickly switch between different working modes, such as high-speed mode, low-speed mode, and automatic mode. Through the independent control panel design, each operator can independently set the working mode according to their own experimental needs without interference, significantly improving work efficiency.

[0028] Meanwhile, the operator can adjust the opening of the damper 14 in the exhaust duct 13 according to the experimental requirements. For example... Figure 1 As shown, the damper 14 is connected to the handle 15 on the outside of the platform 1 via a connecting rod. The rotation angle of the handle 15 is proportional to the opening of the damper 14. By rotating the handle 15, the operator can flexibly adjust the opening of the damper 14, thereby controlling the exhaust volume and ensuring airflow balance in the operating area. This design is particularly suitable for experimental scenarios requiring different exhaust conditions, meeting diverse experimental needs.

[0029] During prolonged use, the energy consumption monitoring module 16 continuously collects data on the operating power of the fan 5 and the resistance of the high-efficiency filter 6, and transmits the data to the control unit for analysis and processing. When no personnel activity is detected in the operating area, the control unit automatically reduces the speed of the fan 5 to a low-power mode, thereby reducing energy consumption. This energy-saving function is particularly suitable for low-load applications in laboratory or medical environments, significantly reducing the operating costs of the equipment.

[0030] In summary, this invention achieves uniform airflow distribution within the operating area through the design of the zoned airflow adjustment mechanism 3, solving the problem of uneven airflow distribution in traditional clean benches. The independent control panel 4 provides convenience for dual-person operation; each operator can independently set the working mode according to their needs without interference. The overall structure is compact, easy to install and maintain, and suitable for widespread application in laboratory and medical environments. The combination of the above steps and principles ensures the equipment's high efficiency, energy saving, and ease of operation in practical applications.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
