Problems solved by technology

Due to the thinness of the diffuser hole, repeated wiping around the diffuser hole will easily cause the burr of the diffuser hole, damage the diffuser hole and the wiping cloth, and once the diffuser hole is burr, it is easier to absorb dust and affect the clean working environment of the purification workbench

Embodiment 1

[0028] like Figure 1-3 As shown, an easy-to-clean laboratory purification workbench includes a workbench body 2 and an isolation cover 4 arranged on the workbench body 2. The front side and bottom end of the isolation cover 4 are respectively opened. The back side of the isolation cover 4 is provided with an air supply device 6 and a diffuser plate 8 sequentially forward, and a sterilizing device 12 is also provided inside the isolation cover 4 and below the top wall 42 . The diffuser plate 8 is provided with a number of diffuser holes 81 , and the peripheral edge of each diffuser hole 81 is provided with an annular protrusion 82 on the diffuser plate 8 . The surface of the annular protrusion 82 is a smooth curved surface.

[0029] Specifically, the workbench body 2 includes a horizontal work platform 21 and a column support 22 vertically supporting the work platform 21 . The working platform 21 includes a square worktop 211 . The opening edge of the bottom end of the isolat...

Embodiment 2

[0032] like Figure 4 As shown, an easy-to-clean laboratory purification workbench differs from Embodiment 1 in that: the longitudinal section shape of the surface of the annular protrusion 82 is a semicircular arc 822, and the inner peripheral side of the annular protrusion 82 is aligned with the The wall 811 of the diffusion hole 81 is tangent to each other.

Embodiment 3

[0034] like Figure 5 As shown, an easy-to-clean laboratory purification workbench differs from Embodiment 2 in that: the connection between the outer peripheral side of the annular protrusion 82 and the front side 83 of the diffuser plate 8 is a rounded corner 14 .

[0035] When the purification workbench of the present embodiment 1-3 is used, the dust and particles are not easy to adhere to the surface of the diffuser hole 81 and get stuck in the diffuser hole 81, even if there is adhesion and jamming, the cleaning is relatively easy and lint-free side, greatly reducing the cleaning time and improving the efficiency of the purification workbench.

Abstract

The invention relates to an easily cleaned laboratory clean workbench which comprises a workbench body and an isolating case arranged on the workbench body, wherein an opening is formed in the front side of the isolating case, an air feeding device and a diffusion plate are sequentially ahead arranged at the back side of the isolating case, sterilization devices are also arranged inside the isolating case and below the top wall of the isolating case, the easily cleaned laboratory clean workbench is characterized in that a plurality of diffusion holes are formed in the diffusion plate, circular bulges are arranged on the peripheral edges of the diffusion holes and the diffusion plate, and the surfaces of the circular bulges are smooth curved surfaces. According to the laboratory clean workbench, the circular bulges are arranged on the peripheral edges of the diffusion holes and the diffusion plate, the thickness and strength of the diffusion holes can be increased through the circular bulges, the laboratory clean workbench is not easy to bur after being repeatedly wiped, dust and particles are prevented from accumulating at corners of burs, the shape and the structure of the diffusion holes can be protected, the cleaning difficulty can be lowered, the working efficiency can be improved, and the service life of a wiping material can be prolonged.

Description

technical field [0001] The invention relates to a laboratory appliance, in particular to a purification workbench. Background technique [0002] The purification workbench is a kind of air purification equipment with strong versatility to provide a local high-cleanness working environment. Its use has good effects on improving process conditions, improving product quality and increasing yield. It can also be connected into an assembly line. It has the advantages of low noise and strong mobility. Widely used in medical and health, biopharmaceutical, food, medical science experiments, optics, electronics, aseptic room experiments, aseptic microbial inspection, plant tissue culture inoculation and other research and production departments that require a local clean and sterile working environment. [0003] In the specific space of the clean bench, clean air flows in a set direction to form an airflow. According to the airflow direction, the existing purification workbench can...
