Standing and sitting dual-purpose fume hood

Abstract

A standing and sitting dual-purpose fume hood comprises a fume hood body. The fume hood body is formed by combining an upper cabinet, a table board, a lower cabinet, a water pipe, wire and gas pipe containing interlayer together. The table board is arranged on the lower cabinet and in the upper cabinet. The standing and sitting dual-purpose fume hood is characterized in that a movable storage cabinet capable of ascending and descending is arranged in the lower cabinet; a water pipe, wire and gas pipe overhauling space is reserved in the lower cabinet; the movable storage cabinet capable of ascending and descending, the reserved water pipe, wire and gas pipe overhauling space and lifting castors mounted at the bottoms of four stand columns of the storage cabinet constitute the standing and sitting dual-purpose fume hood. The purposes to be realized are that a storage cabinet with a single function is created into a four-wheel drive multifunctional storage cabinet on the basis of not changing the basic structure of an existing fume hood to replace a laboratory chair and realize the standing and sitting purposes of the fume hood.

Description

technical field [0001] The invention relates to the technical field of laboratory appliances, in particular to a dual-purpose fume hood for standing and sitting. Background technique [0002] The production of the existing fume hood is basically a combination of the upper cabinet, the table and the lower cabinet. The upper cabinet is the experimental operation space and the focus of production. Various functions are relatively complete. The table is the pretreatment work surface before the experiment. The lower body cabinet is mainly used for storing lockers and reserved maintenance space for water and electricity pipelines; a laboratory fume hood patent (2013203544605) proposes that the lower layer (lower body cabinet) is provided with storage that can move back and forth relative to the cabinet body cabinet, if attached figure 1 As shown, although the locker has realized the forward and backward displacement for easy maintenance, it still only plays the function of the lo...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: on the basis of basically not changing the basic structure of the existing fume hood, innovate the single-function locker into a 4-wheel drive multifunctional locker, replace the experimental chair, and realize the function of the fume hood. It is dual-purpose for standing and sitting; its technical effect is: first, the laboratory chair is replaced by a locker, which saves laboratory space and reduces the investment in laboratory construction; In the room, in order to avoid cross-infection of viruses, follow the principle of single flow direction, and strictly control the airflow, material flow, and human flow. For example, it is strictly forbidden to move chairs from the reagent preparation area to the sample processing area or PCR amplification area or product analysis area. , and the chair is a tool that can be easily moved. In order to avoid cross-infection, the number of seats needs to be limited, but in order to improve the detection accuracy, it is necessary to sit and do experiments, and the fixed single-function locker , changed to a mobile type, can be lifted, and can be used for both sitting and standing, providing a humanized functional service for different heights of experimenters who are standing and doing experiments; third, it is convenient for the maintenance of water, electricity and gas pipelines, and reduces the maintenance workers' workload. Labor intensity and difficulty of assembly and disassembly. During maintenance, because the locker can be completely moved outside the fume hood, the maintenance space and brightness are increased, and humanized functional services are provided for the maintenance personnel. Fourth, according to the length of the fume hood, Equipped with two or three mobile lockers, when there are many biochemical testers, all of them will be moved out as seats, when one is doing the test, one mobile locker will be pushed out, and when the pipeline is inspected, all the lockers will be pushed out, which is flexible and convenient for work Fifth, in the laboratory where logistics is strictly restricted, the locker can be used as a simple handling tool to carry the existing utensils and articles in the laboratory, so as to reduce the risk of cross-infection of foreign supplies without disinfection probability
