Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laboratory cabinets, in particular to a bottom surface exhaust type laboratory cabinet. Background Art
[0002] Laboratory cabinets are essential items in laboratories, and most experiments need to be conducted on chemical laboratory cabinets. When conducting chemical experiments on laboratory benches, some toxic and harmful substances are easily produced. The existing laboratory benches set the exhaust components above the laboratory cabinets, so that the generated dangerous gases flow from bottom to top and are sucked away, making it easier for operators to accidentally inhale the gases, increasing the danger to the operators themselves. For this reason, we propose a bottom exhaust type laboratory bench cabinet. Utility Model Content
[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a bottom exhaust type laboratory table cabinet.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a bottom exhaust type laboratory cabinet, comprising a laboratory cabinet and a laboratory table top, wherein a storage slot is provided inside the laboratory cabinet, a bottom bin connected to the storage slot is provided inside the laboratory cabinet, a fan for sucking air from the storage slot is provided inside the bottom bin, an installation slot is provided on the top of the laboratory table top, a support table plate that fits in the installation slot is provided inside the installation slot, and an air suction slot for ventilation is provided inside the support table plate.
[0005] Preferably, when the fan is started to suck air into the support table through the storage slot, the chemical substances above the support table and the chemical gases inside the experimental table are absorbed through the suction slot.
[0006] Preferably, a collection filter plate for collecting chemical substances is provided inside the storage tank.
[0007] Preferably, a garbage placement groove is provided on the surface of the experimental table, a hook structure is installed on the inner side of the garbage placement groove through a connecting piece, and a collection net for collecting chemical solid waste is arranged inside the garbage placement groove, and the collection net itself has deformation characteristics.
[0008] Preferably, the interior of the collecting net is hook-connected with the exterior of the hook structure via a hook groove.
[0009] Preferably, the interior of the experimental cabinet is provided with a bottom trough connected to the garbage placement trough, the interior of the bottom trough is provided with a collection box for collecting liquid garbage, and one side of the inner edge of the bottom trough is movably connected with a closed cabinet door through a hinge.
[0010] Beneficial Effects
[0011] The utility model provides a bottom exhaust type laboratory cabinet, which has the following beneficial effects:
[0012] (1) This is a bottom-exhaust type laboratory cabinet. In this article, when the operator performs chemical experiments on the laboratory table inside the cabinet, the table top of the laboratory table is provided with a detachable support table through an installation slot. When the fan inside the bottom bin is started, the fan can suck air into the storage tank, so that the dangerous gas generated above the support table is directly sucked into the storage tank through the suction groove, thereby avoiding the gas upward absorption flow process. The chemical hazardous particles on the upper surface of the support table can also be sucked into the collection filter plate inside the storage tank through the suction groove, thereby achieving the effect of improving the health of the operator himself.
[0013] (2) A bottom-exhaust type laboratory cabinet has a garbage placement trough inside the cabinet for placing experimental garbage. The inner side of the garbage placement trough is fastened with a collection net through a plurality of hook structures. The collection net itself has a deformation property. When chemical solid and liquid garbage is put into the garbage placement trough, the collection net can separate the solid garbage, while the liquid garbage penetrates downward through the collection net and is discharged, thereby avoiding the harm caused by the contact reaction between the solid and liquid garbage, thereby achieving the effect of facilitating the solid-liquid separation of chemical garbage.
[0014] (3) In a bottom exhaust type laboratory cabinet, a bottom groove is provided at the bottom of the garbage placement groove, and a collection box is placed inside the bottom groove. When the solid garbage is blocked and filtered by the collection net, the liquid garbage will be discharged downward and flowed. In this way, the liquid garbage can be collected by the collection box. When the cabinet door is opened later, the collection box can be taken out and cleaned, thereby achieving the effect of facilitating the subsequent collection and cleaning of the liquid garbage.
