Easily-cleaned biosafety cabinet

Abstract

The invention relates to an easily-cleaned biosafety cabinet which comprises a cabinet body and a window body and is characterized in that a lifting device, an uplifting device and a control circuit part are arranged on the window body; the uplifting device comprises a rotating shaft bracket, a connecting plate and a connecting shaft; the lifting device comprises a combination plate and glass guide rails arranged at two sides of a glass body, a lifting motor, a rotating shaft and two steel rope idler wheels respectively fixed at two ends of the rotating shaft are fixed on the combination plate; the two steel rope idler wheels are connected with the glass body through steel ropes, the rotating shaft is fixed on the combination plate through at least two support bearings; and the combination plate is fixed with the connecting plate. According to the invention, the convenience for using the biosafety cabinet and the better sealing property of an operation region are ensured, and the convenience for wiping the inner surface of the glass body is ensured. The cabinet body and glass can be easily cleaned without dead angles; and the environment inside the cabinet body can be prevented from being polluted due to no need of other sealing fixtures, thus an operator conveniently uses the biosafety cabinet.

Description

technical field [0001] The invention relates to an easy-to-clean biological safety cabinet, more specifically, to an easy-to-clean biological safety cabinet whose windows have functions of lifting and rotating. Background technique [0002] When the biological safety cabinet is used for related experiments normally, a negative pressure is formed inside the safety cabinet, and the air flow enters the cabinet from the front windshield, passes through the ventilation channel, and enters the fan suction port, and then the fan pushes the air flow to distribute to the upper and lower filters, passing through The airflow from the upper filter is directly discharged indoors or outdoors, and the airflow through the lower filter enters the operating area, merges with the airflow from the suction hole and enters the next repeated cycle process. Different experiments require the use of different experimental equipment and preparations, and some require water and air to provide water an...

AI Technical Summary

Problems solved by technology

Different experiments require the use of different experimental equipment and preparations, and some require water and air to provide water and air to support the experiment. All of them need to face the same problem: the cleaning of the safety cabinet

[0003] The windows of traditional safety cabinets have two arrangements: one is that the glass guide rail is fixedly installed in front of the cabinet body, and the glass moves up and down along the front of the cabinet body in the guide rail. When the safety cabinet needs to be cleaned, the glass rises to the highest point. Clean the inside of the cabinet. However, it is more troublesome to clean the upper end of the inside of the safety cabinet glass. It needs to disassemble the glass or the cleaning personnel are inside the cabinet, and the glass can only be cleaned by falling down.

No matter which cleaning method is used, it is inconvenient for customers; the upper end of the inner glass of the safety cabinet has become a dead corner for cleaning of ordinary safety cabinets

The other is that the glass is fixed on the front frame, the window can be rotated and lifted, but the glass cannot slide up and down. This can be very convenient to clean the cabinet and glass, but when the operator finishes the experiment, another seal is required. The tooling seals the front window operation port, which makes it inconvenient to use
