Description

Technical Field

[0001] This utility model belongs to the technical field of biosafety equipment, specifically relating to a benchtop biosafety cabinet. Background Technology

[0002] A benchtop biosafety cabinet is a laboratory device designed to protect laboratory personnel, the environment, and experimental materials from contamination by potentially hazardous biological agents. It creates a safe working environment by using high-efficiency particulate matter (HEPA) filters to capture tiny particles and microorganisms, and by controlling airflow inside and outside the cabinet through a specific airflow design.

[0003] Key features of benchtop biosafety cabinets include a high-efficiency air filtration system, a stable airflow pattern, and a commonly equipped ultraviolet lamp for sterilization. These cabinets are suitable for biosafety levels 1-3 laboratories, especially when handling experimental materials that may generate aerosols. They are widely used in research, teaching, clinical testing, and production in fields such as microbiology, biomedicine, genetic engineering, animal experiments, and biopharmaceuticals.

[0004] However, after the operation is completed, the debris on the work surface of the benchtop biosafety cabinet is usually scattered, which is time-consuming to clean.

[0005] This utility model addresses the above-mentioned problems by providing a tabletop biosafety cabinet that facilitates the cleaning of debris and garbage. Utility Model Content

[0006] The purpose of this invention is to provide a benchtop biosafety cabinet to solve the problem mentioned in the background art that the debris on the working surface of the benchtop biosafety cabinet is usually scattered after operation, which is time-consuming to clean.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a benchtop biosafety cabinet, comprising a biosafety cabinet body and an operating workbench disposed at the middle position of the biosafety cabinet body;

[0008] A rear movable brush is provided on the rear side of the operating workbench. A limiting groove is provided in the middle of the rear movable brush. A movable connecting slider is provided in the middle of the limiting groove. A connecting flip bar is provided on the upper side of the movable connecting slider. A flip side inner brush is provided at the end of the connecting flip bar. The connecting flip bar is rotatably connected to the flip side inner brush and the movable connecting slider via a rotating shaft. A flip side outer brush is provided on the outer side of the end of the flip side inner brush. A flip connecting block is provided at the end of the flip side outer brush. A connecting compression spring is provided inside the flip connecting block. A snap-fit ​​slope column is provided on the upper side of the connecting compression spring. A groove is provided on the front side of the operating workbench. The impurity discharge hopper is located below the groove. When the rear movable brush is pushed and pulled, it will cause the flip side inner brush to flip through the connecting flip bar. During the forward movement, the flip side inner brush gradually becomes aligned with the rear movable brush. This improvement drives the impurities on the operating workbench to the front, and it can perform a second brushing with a single movement.

[0009] Preferably, a first telescopic body is provided at the upper side of the snap-fit ​​slope column, and a second telescopic body is provided at the end of the first telescopic body.

[0010] Preferably, a data display screen is provided at the front of the biosafety cabinet, and the surface of the data display screen is covered with a protective film.

[0011] Preferably, an adjustment control button is provided on the side of the data display screen, and the adjustment control button is used to control the biosafety cabinet.

[0012] Preferably, the biosafety cabinet is provided with bottom support legs at the bottom position, and the bottom support legs are connected to the biosafety cabinet by welding.

[0013] Preferably, a bottom connecting caster wheel is provided at the bottom position of the bottom support leg, and the bottom connecting caster wheel is installed and connected to the bottom side position of the bottom support leg by screws.

[0014] Preferably, the biosafety cabinet is provided with an upper ventilation port, which is connected to the operating workbench via an internal ventilation motor.

[0015] Compared with the prior art, this utility model provides a benchtop biosafety cabinet with the following advantages:

[0016] In a benchtop biosafety cabinet, a rear movable brush is installed on the rear side of the operating table. A limit groove is located in the middle of the rear movable brush, and a movable connecting slider is located in the middle of the limit groove. A connecting flip bar is located above the movable connecting slider, and a flip side inner brush is located at the end of the connecting flip bar. The connecting flip bar is rotatably connected to the flip side inner brush and the movable connecting slider via a rotating shaft. A flip side outer brush is located at the outer end of the flip side inner brush, and a flip connecting block is located at the end of the flip side outer brush. A connecting compression spring is located inside the flip connecting block, and a locking slope is located above the connecting compression spring. The column has a groove on the front side of the operating table, with a hopper for waste disposal located below the groove. A rear-mounted moving brush, when pushed and pulled, causes a rotating inner brush on the rotating side to rotate via a connecting rotating strip. As the inner brush moves forward, it gradually aligns with the rear moving brush. This improvement drives debris on the operating table to the front, allowing for a second scrubbing with a single movement. With this improvement, impurities and waste can be pushed forward and fall into the waste disposal hopper for centralized processing. This improvement enables efficient and rapid recycling of experimental waste, reducing contamination of the biosafety cabinet and minimizing human contact with waste. Attached Figure Description
