[0002] A biosafety cabinet is a box-type air purification negative pressure safety device that can prevent the aerosol escape of certain dangerous or unknown biological particles during the experimental operation process. It is widely used in scientific research, teaching, clinical testing, and production in fields such as microbiology, biomedicine, genetic engineering, and biological products. It is the most basic safety protection equipment in the primary protection barrier of laboratory biosafety. The air curtain isolation biosafety cabinet isolates the internal and external environments of the operation area through the air curtain to avoid harm to people and the environment. It is a relatively safe biosafety cabinet and has a good effect on improving process conditions and protecting the health of operators. Therefore, there is a particular need for an air curtain isolation biosafety cabinet.

[0003] However, for the existing air curtain isolation biosafety cabinets, after use, the inside of the cabinet body needs to be cleaned. People usually use a wiping tool to reach into the inside of the biosafety cabinet to wipe the inner wall.

[0023] Please refer to Figure 1-5, the present utility model provides a technical solution: an air curtain isolation biological safety cabinet, which includes a cabinet body 1 and a cleaning mechanism 4. Rolling wheels 2 are installed at the bottom of the cabinet body 1, an air curtain box 3 is installed at the top of the cabinet body 1, and a cleaning mechanism 4 is arranged inside the cabinet body 1;

[0024] The cleaning mechanism 4 includes a support base 401, a sterilization lamp 402, and a servo motor 405. The support base 401 is installed on the inner bottom surface of the cabinet body 1, and the sterilization lamp 402 is installed on the inner top surface of the cabinet body 1. A limit groove 403 is provided on one side of the surface of the support base 401, and a sliding groove 404 is provided on the other side of the surface of the support base 401. A servo motor 405 is installed at one end of the support base 401. A limit rod 406 is arranged inside the limit groove 403, and a one-way lead screw 407 is arranged inside the limit groove 403. One end of the one-way lead screw 407 penetrates through a slider 408. One end of the slider 408 is fixedly connected to a transverse mounting plate 409, and the other end of the slider 408 is fixedly connected to a longitudinal mounting plate 410. A longitudinal brush 411 is installed on one side of the surface of the transverse mounting plate 409, a longitudinal cleaning block 412 is installed on one side of the surface of the transverse mounting plate 409, a transverse brush 413 is installed on one side of the surface of the longitudinal mounting plate 410, and a transverse cleaning block 414 is installed on one side of the surface of the longitudinal mounting plate 410. Through the settings of the support base 401, the sterilization lamp 402, the limit groove 403, the sliding groove 404, the servo motor 405, the limit rod 406, the one-way lead screw 407, the slider 408, the transverse mounting plate 409, the longitudinal mounting plate 410, the longitudinal brush 411, the longitudinal cleaning block 412, the transverse brush 413, and the transverse cleaning block 414, when it is necessary to clean the inside of the cabinet body 1, the servo motor 405 can be turned on. At this time, the servo motor 405 drives the one-way lead screw 407 to rotate inside the limit groove 403. Since the slider 408 is fitted inside the limit groove 403, and the slider 408 is threadedly sleeved on the surface of the one-way lead screw 407, and at the same time the limit rod 406 penetrates through the slider 408 and both ends are fixedly connected to the support base 401 inside the limit groove 403. Therefore, when the one-way lead screw 407 rotates inside the limit groove 403, the slider 408 moves along the one-way lead screw 407 and the limit rod 406 inside the limit groove 403. Since one end of the slider 408 is fixedly connected to the transverse mounting plate 409, and the other end of the slider 408, the sliding groove 404, is fixedly connected to the longitudinal mounting plate 410. Therefore, when the slider 408 moves inside the limit groove 403, the slider 408 drives the transverse mounting plate 409 and the longitudinal mounting plate 410 to move. Since one end of the longitudinal brush 411 is in contact with the inner bottom surface of the cabinet body 1, one end of the longitudinal cleaning block 412 is in contact with the inner bottom surface of the cabinet body 1, one end of the transverse brush 413 is in contact with the inner side wall of the cabinet body 1, and one end of the transverse cleaning block 414 is in contact with the inner side wall of the cabinet body 1. Therefore, the longitudinal brush 411 and the longitudinal cleaning block 412 brush and clean the inner bottom surface of the cabinet body 1, and the transverse brush 413 and the transverse cleaning block 414 brush and clean the inner wall of the cabinet body 1, so as to clean the inside of the cabinet body 1. Subsequently, the sterilization lamp 402 is turned on. Since the sterilization lamp 402 is an ultraviolet lamp, the sterilization lamp 402 can perform a sterilization treatment on the inside of the cabinet body 1.

[0025] Further, four sets of rollers 2 are provided, and the rollers 2 are universal braking wheels. With the setting of the rollers 2, during use, since the rollers 2 are universal braking wheels, the rollers 2 can drive the cabinet 1 to move.

[0026] Further, eight sets of sterilization lamps 402 are provided. The sterilization lamps 402 are equally spaced in two rows. The sterilization lamps 402 are ultraviolet lamps. With the setting of the sterilization lamps 402, during use, when the sterilization lamps 402 work, they can disinfect the bacteria inside the cabinet 1.

[0027] Further, the chute 404 communicates with the limiting groove 403. The output shaft of the servo motor 405 is connected to the one-way lead screw 407. With the setting of the servo motor 405, during use, turning on the servo motor 405 can drive the one-way lead screw 407 to rotate inside the limiting groove 403.

[0028] Further, one end of the limiting rod 406 passes through the inside of the slider 408, and both ends of the limiting rod 406 are fixedly connected to the support base 401 inside the limiting groove 403. With the setting of the limiting rod 406, during use, the limiting rod 406 can further limit the slider 408 to prevent the slider 408 from deviating in direction during movement.

[0029] Further, the slider 408 is threadedly sleeved on the surface of the one-way lead screw 407. The slider 408 is fitted inside the limiting groove 403, and one end of the slider 408 passes through the chute 404. With the setting of the slider 408, during use, when the slider 408 slides inside the limiting groove 403, it can drive the transverse mounting plate 409 and the longitudinal mounting plate 410 to move.

[0030] Further, one end of the longitudinal brush 411 is in contact with the inner bottom surface of the cabinet 1, one end of the longitudinal cleaning block 412 is in contact with the inner bottom surface of the cabinet 1, one end of the transverse brush 413 is in contact with the inner side wall of the cabinet 1, and one end of the transverse cleaning block 414 is in contact with the inner side wall of the cabinet 1. With the setting of the longitudinal brush 411, the longitudinal cleaning block 412, the transverse brush 413 and the transverse cleaning block 414, during use, when the longitudinal brush 411 and the longitudinal cleaning block 412 move, they can brush and clean the inner bottom surface of the cabinet 1, and when the transverse brush 413 and the transverse cleaning block 414 move, they can brush and clean the inner wall of the cabinet 1.

[0031] Working principle: Move the cabinet body 1 to the required position through the roller 2. When it is necessary to clean the inside of the cabinet body 1, the servo motor 405 can be turned on. At this time, the servo motor 405 drives the one-way lead screw 407 to rotate inside the limit groove 403. Since the slider 408 is fitted inside the limit groove 403 and the slider 408 is threadedly sleeved on the surface of the one-way lead screw 407, and at the same time the limit rod 406 passes through the slider 408 and both ends are fixedly connected to the support base 401 inside the limit groove 403. Therefore, when the one-way lead screw 407 rotates inside the limit groove 403, the slider 408 moves along the one-way lead screw 407 and the limit rod 406 inside the limit groove 403. Since one end of the slider 408 is fixedly connected to the horizontal mounting plate 409 and the other end of the slider 408, the chute 404, is fixedly connected to the vertical mounting plate 410. Therefore, when the slider 408 moves inside the limit groove 403, the slider 408 drives the horizontal mounting plate 409 and the vertical mounting plate 410 to move. Since one end of the longitudinal brush 411 is in contact with the inner bottom surface of the cabinet body 1, one end of the longitudinal cleaning block 412 is in contact with the inner bottom surface of the cabinet body 1, one end of the horizontal brush 413 is in contact with the inner side wall of the cabinet body 1, and one end of the horizontal cleaning block 414 is in contact with the inner side wall of the cabinet body 1. Therefore, the longitudinal brush 411 and the longitudinal cleaning block 412 brush and clean the inner bottom surface of the cabinet body 1, and the horizontal brush 413 and the horizontal cleaning block 414 brush and clean the inner wall of the cabinet body 1, thereby cleaning the inside of the cabinet body 1. Subsequently, turn on the sterilization lamp 402. Since the sterilization lamp 402 is an ultraviolet lamp, the sterilization lamp 402 can perform a sterilization treatment on the inside of the cabinet body 1.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
