[0024] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] like Figure 1-Figure 3 shown.

[0027] A laboratory workbench comprises a workbench body, an air filtering device, a waste liquid collecting device, a dustproof device, a disinfecting device and a gas generating device.

[0028] The workbench body includes a laboratory cabinet, support columns, and universal wheels 5. Four support columns are installed at the bottom of the laboratory cabinet, and universal wheels 5 are arranged at the bottom of the support columns. An air filter device, a waste liquid collection device, a dust prevention device, a disinfection device, and a gas generating device are arranged inside the laboratory cabinet.

[0029] An operation panel 6 is provided inside the experimental cabinet, and the operation panel 6 can control the operation, stop, timing and operating power of each device.

[0030] An air filter device is provided on one side of the test cabinet, and the air filter device includes an intelligent fan 2 and a primary filter 1. The intelligent fan 2 filters the air inside the test cabinet through the primary filter 1 and then discharges it out of the test cabinet. The intelligent fan 2 can adjust the exhaust air volume according to the operation panel 6. When the air inside the test cabinet causes some substances or particles to gather in the air and the concentration in the air increases due to experiments or operations, the air inside the test cabinet needs to be filtered and discharged through the primary filter 1. At the same time, fresh air is obtained from the outside of the test cabinet to enter the test cabinet to continue the experiment. If the air filtered by the primary filter 1 meets the emission standards, it will enter the exhaust fan for discharge. If it does not meet the air emission standards, it will enter the air purifier for further filtration and treatment.

[0031] During the experiment, due to operational errors, dangerous reagents were spilled in the operating area of ​​the laboratory cabinet. At this time, a waste liquid collection device is provided inside the laboratory cabinet, which can collect the waste liquid spilled inside the laboratory cabinet. The waste liquid collection device includes a groove, an anti-corrosion hose, and a waste liquid collection bucket. The groove is provided inside the laboratory cabinet, and other planes inside the laboratory cabinet are higher than the groove, so that the waste liquid spilled inside the laboratory cabinet can flow along the inside of the laboratory cabinet into the groove. One end of the anti-corrosion hose is connected to the bottom of the groove, and the other end of the anti-corrosion hose is provided above the waste liquid collection bucket. The waste liquid inside the laboratory cabinet will be able to converge into the groove along the bottom surface, and the waste liquid flowing into the groove can flow along the anti-corrosion hose into the waste liquid collection bucket.

[0032] A dustproof device is provided on the outside of the laboratory cabinet, and the dustproof device includes a dustproof curtain 16. The dustproof curtain 16 is fixed to the side of the workbench. A dustproof curtain fixing position 7 is provided on the top of the side of the workbench. A circular magnet 15 is provided on the dustproof curtain 16 at a position corresponding to the dustproof curtain fixing position 7. The dustproof curtain 16 is fixed to the outside of the laboratory cabinet by the circular magnet 15 and the dustproof curtain fixing position 7. The dustproof curtain 16 is made of polyester pongee material, and a circular magnet 15 is provided at the edge of the dustproof curtain 16. The dustproof curtain 16 can more strictly prevent dust from the workbench. At the same time, when the disinfection device is started, the operation panel 6 does not start the disinfection device if it does not detect that the dustproof curtain 16 is fixed to the dustproof curtain fixing position 7.

[0033] A lighting device is provided at the upper position inside the experimental cabinet. In this embodiment, the lighting device is a light pipe 10. A movable glass 9 is provided near the light pipe 10. When the light pipe 10 fails, the movable glass 9 can be adjusted to replace the light pipe 10. The light pipe 10 can be started by the control operation panel 6, and the light intensity can be adjusted by the control operation panel 6.

[0034] A disinfection device is provided inside the experimental cabinet. In this embodiment, the disinfection device adopts an ultraviolet light tube 8. When the disinfection device is started in the operation panel 6, the disinfection device will be started with a delay of a period of time. After a period of time, it is detected whether the dust curtain 16 is fixed on the dust curtain fixing position 7. When the dust curtain 16 is fixed on the side of the experimental cabinet, the disinfection device remains turned on and lasts for a period of time.

[0035] A gas generator 11 is also provided inside the test cabinet, and the gas generator 11 can generate a certain amount of chlorine dioxide, which can further disinfect the test cabinet. The gas generator 11 includes a hollow cover 12, a control module 13, and a nozzle 14. The control module 13 is provided with a timing device inside, and the operation panel 6 can delay the start of the gas generator 11. A chlorine dioxide generating device is provided inside the nozzle 14, and the generated chlorine dioxide can diffuse from the hollow cover 12 to the inside of the test cabinet to disinfect the inside of the test cabinet. The gas generator 11 is selected as a common chlorine dioxide generating device on the market. Before starting the gas generator 11, the operation panel 6 detects whether the dust curtain 6 is fixed to the side of the test cabinet and whether the air filter device has a fault. The gas generator 11 is started only when the dust curtain 6 and the air filter device are operating normally.

[0036] When the operation panel 6 detects that the dust curtain 6 is fixed on the side of the laboratory cabinet and the air filter device is operating normally, the disinfection device is started. At this time, the ultraviolet light tube 8 is started to disinfect the experimental area inside the laboratory cabinet. Because the disinfection effect of the ultraviolet light tube 8 is not good, in order to improve the cleanliness level in the safety bench, the gas generating device 11 is started at this time. The gas generating device 11 generates a certain amount of chlorine dioxide to further disinfect the inside of the laboratory cabinet, thereby further enhancing the cleanliness level in the safety bench.

[0037] The working steps of this embodiment are to confirm whether the air filter device, the waste liquid collection device and the disinfection device can be used normally before conducting the experiment.

[0038] Before starting the experiment, turn on the ultraviolet light tube 8 and irradiate for 5-10 minutes to kill bacteria on the surface of the workbench. Make sure that the dust curtain 16 is installed when starting the ultraviolet light tube 8. Prevent the operator from being directly exposed to the ultraviolet light tube, which may cause certain damage to the skin and eyes.

[0039] After the ultraviolet light tube 8 has been irradiated for a period of time, the ultraviolet light tube 8 is turned off and the air filtering device is started.

[0040] Conduct experimental operations. A waste liquid collection device is provided inside the workbench. When reagents, samples and other liquids are spilled during the experiment, the waste liquid inside the workbench can flow from the bottom of the workbench into the waste liquid collection device. A groove is provided on the bottom of the workbench, and an anti-corrosion hose is provided inside the groove. One end of the anti-corrosion hose is connected to the waste liquid collection bucket.

[0041] After the experiment, clean the workbench to remove residual samples and contaminants. Cleaning can be done with detergent or disinfectant.

[0042] After cleaning, the workbench is further disinfected using the ultraviolet light tube 8. When it is confirmed that the air filter device can operate normally, the gas generating device 11 is started to disinfect the workbench to further improve the cleanliness of the laboratory workbench.

[0043] After the disinfection is finished, the gas generating device 11 is turned off, the ultraviolet light tube 8 is turned off, and finally the power supply of the workbench is turned off. Ensure that the dust curtain 6 is fixed on the dust curtain 7 through the circular magnet 15.
