Description

Technical Field

[0001] The utility model belongs to the technical field of smear equipment and relates to a glass slide drying and adsorption device. Background Art

[0002] Microbial sample smears are widely used for colony inoculation, culture, separation, and detection, and are an important task in microbial sample detection. After the existing automatic microbial sample smear device smears the sample onto the slide, it also needs to add the layering liquid to the slide through the filling module, so that the liquid content in the sample is high. The liquid on the slide needs to be evaporated before the sample is thermally fixed. In order to evaporate the liquid on the slide, the traditional practice is to dry the slide on the workbench of the smear device, and then proceed to the next step after the liquid on the slide is dry. This not only greatly reduces the work efficiency of the smear, but also causes the aerosol in the liquid to diffuse into the air, causing air pollution. Utility Model Content

[0003] The utility model aims to solve the above problems in the prior art and proposes a glass slide drying adsorption device which can prevent aerosol diffusion.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] The slide drying adsorption device comprises a main body with a cavity inside, the main body is provided with a placement plane for placing the slide, the cavity is provided with a heating plate located below the placement plane, and also comprises a negative pressure system, the air inlet of the negative pressure system is connected to the cavity, and the placement plane is provided with a plurality of adsorption holes connected to the cavity.

[0006] In the above-mentioned slide drying and adsorption device, a partition is provided in the cavity for dividing the cavity into an upper cavity and a lower cavity, the upper surface of the partition is a placement plane, an insertion port for connecting to the upper cavity is provided on one side of the main body, the lower side surface of the insertion port is flush with the placement plane, the heating plate is located in the lower cavity, and the air inlet of the negative pressure system is connected to the lower cavity.

[0007] The insertion port extends in the horizontal direction, and the glass slide inserted through the insertion port is in a horizontal state, which prevents the position of the sample on the glass slide from changing. The heat generated by the heating plate moves upward to evaporate the liquid on the upper glass slide, with high evaporation efficiency. The aerosol generated by heating is sucked away by the negative pressure system, which can effectively prevent the aerosol from spreading.

[0008] The glass slide is supported by the partition to prevent the glass slide from being uneven during the evaporation process, which can effectively prevent the position of the sample relative to the glass slide from changing.

[0009] In the above-mentioned glass slide drying and adsorption device, the heating plate is attached to the lower surface of the partition. The heating plate is a PTC heating plate, and the heat of the heating plate can be quickly transferred to the glass slide through the partition, thereby improving the evaporation efficiency.

[0010] In the above-mentioned glass slide drying adsorption device, a plurality of adsorption holes are arranged around the glass slide, so as to quickly adsorb the aerosol generated at various places of the glass slide into the lower cavity.

[0011] In the above-mentioned slide drying and adsorption device, the upper cavity has a stopper extending downward from the top of the body on one side of the insertion port. The insertion port is located at the lower side of the upper cavity. Since the upper cavity is higher than the insertion port, when the negative pressure system is not started, the aerosol generated by heating will first enter the upper cavity and will not be discharged from the insertion port.

[0012] In the above-mentioned slide drying and adsorption device, the outer top surface of the main body is provided with a plurality of downwardly recessed placement cavities, the bottom surface of the placement cavities is the above-mentioned placement plane, and the plurality of adsorption holes are arranged around the placement cavities.

[0013] In the above-mentioned slide drying and adsorption device, the heating plate is attached to the inner top surface of the main body.

[0014] In the above-mentioned slide drying adsorption device, the negative pressure system includes an adsorption tube and a fan, the air inlet end of the adsorption tube is communicated with the cavity, and the air outlet end of the adsorption tube is connected to the air inlet of the fan.

[0015] In the above-mentioned slide drying and adsorption device, the air outlet of the fan is connected to an exhaust pipe, and the air outlet end of the exhaust pipe is connected to a filter.

[0016] The filter adopts a high-efficiency filter that can capture dust particles larger than 0.5um and various suspended solids. It uses ultra-fine glass fiber paper as filter material, folded offset paper, aluminum foil and other materials as partition plates, sealed with a new type of polyurethane sealant, and is made of galvanized plate, stainless steel plate, and aluminum alloy profile as the outer frame.

[0017] Compared with the prior art, the present glass slide drying and adsorption device has the following advantages: the heating plate heats the glass slide inserted through the insertion port, so that the liquid on the glass slide evaporates quickly with high evaporation efficiency, and absorbs the aerosol generated by heating through the negative pressure system to prevent the aerosol from diffusing.

[0030] like Figure 3 As shown, a plurality of adsorption holes 7 are arranged around the glass slide a, which can quickly adsorb the aerosol generated at various locations of the glass slide a into the lower cavity 6.

The insertion port 3 is located at the lower side of the upper cavity 5. Since the upper cavity 5 is arranged higher than the insertion port 3, when the negative pressure system is not started, the aerosol generated by heating will enter the upper cavity 5 first and will not be discharged from the insertion port 3.
