A biosafety cabinet with a cleaning mechanism

Abstract

This utility model discloses a biosafety cabinet with a cleaning mechanism, including a biosafety cabinet body, an operating base plate, a mounting plate, and a cleaning brush. The mounting plate is fixedly installed inside the biosafety cabinet body, and the operating base plate is inclinedly set at the bottom of the biosafety cabinet body, with the side of the operating base plate closest to the mounting plate being the lower side. The upper surface of the mounting plate is provided with a cleaning component for moving the cleaning brush to clean the side of the drainage groove inside the operating base plate. The surface of the operating base plate is rinsed by water flow, and then the cleaning component drives the cleaning brush to move left and right inside the biosafety cabinet body, and the cleaning brush moves to clean around the drainage groove. A servo motor is started, which drives the cleaning brush to move back and forth in a straight line through the first side arc plate, the connecting column, and the second side arc plate, avoiding the need for repeated forward and reverse rotation of the motor, thereby improving the service life of the motor and preventing the accumulation of dirt on the inside of the operating base plate, thus improving the cleanliness of the biosafety cabinet body.

Description

Technical Field

[0001] This utility model relates to the field of biosafety cabinet technology, specifically a biosafety cabinet with a cleaning mechanism. Background Technology

[0002] Biosafety cabinets are box-type air-purifying negative pressure safety devices that prevent the aerosol release of hazardous or unknown biological particles during experimental operations. They are widely used in scientific research, teaching, clinical testing, and production in fields such as microbiology, biomedicine, genetic engineering, and biological products. They are the most basic safety protection equipment in the primary protection barrier of laboratory biosafety. Some existing biosafety cabinets rely solely on water rinsing for automatic cleaning. While this can achieve some cleaning, the cleaning effect is limited. Stains adhering to the water outlet on the inside of the operating platform are difficult to rinse off, making subsequent cleaning quite troublesome. A search revealed that the prior art, authorized publication number CN212417976U, discloses a biosafety cabinet that is easy to clean, relating to the field of biological equipment technology. The cabinet features gloves installed inside the sleeves, with a zipper connecting the sleeves and gloves. The zipper consists of two straps, each embedded near the sleeve and glove, facilitating glove removal and ensuring a secure connection between the gloves and sleeves to prevent the gloves from slipping off the user's hands during operation. An electric telescopic rod is fixedly installed at the bottom of the cleaning chamber adjacent to the water storage chamber, and a controller is bolted to the front end of the inner wall of the cleaning chamber. A water pump is installed at the rear of the cabinet, directly behind the cleaning chamber. This eliminates the need for manual cleaning of the rotating plate, facilitating user work while maintaining a clean operating environment within the cabinet. The aforementioned patent has the limitation that it can only rely on water rinsing for automatic cleaning, which leads to the accumulation of dirt on the inside of the operating platform, making subsequent cleaning quite troublesome; therefore, we need to propose a biosafety cabinet with a cleaning mechanism.

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.

[0016] This utility model provides: a biosafety cabinet with a cleaning mechanism, such as... Figure 1-4As shown, it includes a biosafety cabinet 1, an operating base plate 5, a mounting plate 6, and a cleaning brush 15. The mounting plate 6 is fixedly installed inside the biosafety cabinet 1. The operating base plate 5 is inclinedly set at the bottom inside the biosafety cabinet 1. The side of the operating base plate 5 closest to the mounting plate 6 is set as the lower side. A drainage groove is opened at the bottom inside the biosafety cabinet 1 and below the mounting plate 6. The cleaning brush 15 is slidably set below the mounting plate 6. The upper surface of the mounting plate 6 is provided with a cleaning component for moving the cleaning brush 15 to clean the side of the drainage groove inside the operating base plate 5.

[0017] Furthermore, the cleaning assembly includes a servo motor 3, a support block 7, a rotating shaft 8, a first side arc plate 9, a connecting column 10, a second side arc plate 11, a rotating column 12, a side support block 13, and a connecting module. The servo motor 3 is bolted to the outside of the biosafety cabinet 1, and the rotating shaft 8 is keyed to the output end of the servo motor 3. The support block 7 and the side support block 13 are both fixedly installed on the upper surface of the mounting plate 6. The rotating shaft 8 rotates through the support block 7, and the rotating column 12 is rotatably positioned on the side of the side support block 13 near the support block 7. The first side arc plate 9 is fixedly positioned at the end of the rotating shaft 8 away from the servo motor 3, and the second side arc plate 11 is fixed... The connecting column 10 is fixedly located between the first side arc plate 9 and the second side arc plate 11, on the side of the rotating column 12 away from the side support block 13. The servo motor 3 is started to drive the rotating shaft 8 to rotate, and the rotating shaft 8 is supported by the support block 7. The rotating shaft 8 drives the first side arc plate 9 to rotate. The first side arc plate 9, the connecting column 10 and the second side arc plate 11 are all inclined, and the first side arc plate 9 and the second side arc plate 11 are inclined at both ends of the connecting column 10. The rotating column 12 is supported by the side support block 13, thereby ensuring that the first side arc plate 9, the connecting column 10 and the second side arc plate 11 can rotate normally.

[0018] It is worth noting that the connecting module includes a sliding block 14, a traction block 17, a traction frame 20, a connecting rod 21, and a mounting frame 22. The traction block 17 is fixedly installed on the outer arc surface of the connecting column 10, and the cleaning brush 15 is fixedly installed on the lower surface of the sliding block 14. Two sets of traction frames 20 are provided, and the connecting rod 21 is fixedly installed between the two sets of traction frames 20. The mounting frame 22 is rotatably connected to the traction frame 20 on the side away from the sliding block 14, and is rotatably connected to the end of the traction block 17 away from the connecting column 10.

Two sets of limiting posts 16 are rotatably provided between the support block 7 and the side support block 13, and the sliding block 14 is slidably sleeved on the outer arc surface of the two sets of limiting posts 16. The upper surface of the mounting plate 6 has a through opening for the cleaning brush. When the cleaning groove 18 corresponding to brush 15 is started, the first side arc plate 9, the connecting column 10 and the second side arc plate 11 tilt and rotate, thereby driving the traction block 17 to move left and right. The traction block 17 drives the mounting frame 22 to move. The mounting frame 22 drives the connecting rod 21 to move through a set of traction frames 20. The connecting rod 21 drives the sliding block 14 to move left and right through another set of traction frames 20. The sliding block 14 is limited by two sets of limit columns 16 and the traction frame 20 is limited by the stop block 19, ensuring that the traction frame 20 can drive the sliding block 14 to move. At the same time, the limit columns 16 ensure that the sliding block 14 can move linearly along the limit columns 16. Thus, the cleaning groove 18 drives the cleaning brush 15 to clean the inside of the operating base plate 5, thereby improving the cleanliness of the biosafety cabinet 1.

[0019] Specifically, the lower surface of the biosafety cabinet 1 is fixedly provided with several sets of support legs 2, and the front side of the biosafety cabinet 1 is provided with a closed window 4. The biosafety cabinet 1 is supported by several sets of support legs 2, which facilitates the drainage effect of the drainage channel inside the biosafety cabinet 1.
