Description

Technical Field

[0001] The utility model relates to the technical field of MNS sample cabinets, in particular to an MNS sample cabinet with a dustproof ventilation window structure. Background Art

[0002] In traditional MNS sample cabinets, ventilation and dust control often present an intractable conflict. These cabinets typically feature a sealed design, with internal chambers and drawers housing various electrical equipment. Proper ventilation is essential to ensure proper operation of the equipment, relying on ventilation slots, heat sinks, or fan structures to achieve air circulation and dissipate heat. However, this need for ventilation often conflicts with dust control. While larger vents or heat dissipation holes facilitate air circulation, they also facilitate dust ingress, reducing dust control effectiveness. Conversely, emphasizing dust control through tighter sealing can hinder air circulation, compromise heat dissipation, and even cause equipment overheating.

[0003] In addition to the conflict between ventilation and dust control, traditional MNS sample cabinets also present numerous inconveniences when it comes to filter replacement and dust removal. Filter replacement, a crucial component for dust control, is often complex, requiring the disassembly of multiple components to access the filter. This not only increases the difficulty and time required for maintenance, but also increases the time required. Dust removal is often a tedious task. Due to the cabinet's complex structure and numerous blind spots, thorough cleaning is difficult, even with a vacuum cleaner or manual wiping.

[0004] In response to the above problems, the present application proposes an MNS sample cabinet with a dust-proof ventilation window structure. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the prior art of MNS sample cabinets, that ventilation and dust prevention are often a pair of difficult to reconcile contradictions, and the filter is an important component of dust prevention, and its replacement process is usually complicated. An MNS sample cabinet with a dust-proof ventilation window structure is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An MNS sample cabinet with a dustproof ventilation window structure comprises a sample cabinet body, first ventilation holes are provided on both sides of the sample cabinet body, a receiving cavity is provided on one side, and a cabinet door is hinged on the opening side of the receiving cavity;

[0008] a first ventilation assembly comprising a second ventilation hole provided in the cabinet door and a first filter screen inside the second ventilation hole, wherein the first filter screen is detachably fixed by an annular gland and fixing screws, and a door handle is fixedly mounted on the cabinet door;

[0009] The second ventilation assembly comprises a fixed horizontal plate fixed to the side wall of the accommodating cavity and a slidingly installed moving horizontal plate, and a detachable clamping limiting outer frame is arranged between the two;

[0010] The limiting outer frame is internally provided with a filter plate and a second filter screen.

[0011] In a possible design, a fixed support ring is fixedly installed in the limiting outer frame, the second filter screen is clamped on one side of the fixed support ring, and a plurality of support blocks are fixed on the side of the second filter screen facing the filter plate.

[0012] In a possible design, grooves are formed on the two sides of the limiting outer frame, and connecting strip blocks are slidingly arranged through the grooves.

[0013] In a possible design, a fixed strip plate is further arranged, which is fixed to one side of the limiting outer frame and is provided with a plurality of clamping grooves;

[0014] A rotating shaft is fixed to the end of the connecting strip block, and a rotating clamping plate is rotatably arranged on the outer wall of the rotating shaft.

[0015] When the rotating clamping plate is clamped into the clamping groove, the position of the filter plate is fixed, and the overlapping area of the filter plate with the first ventilation hole is changed by sliding the filter plate transversely to adjust the ventilation volume.

[0016] In a possible design, a dust collection box is arranged at the bottom of the accommodating cavity in a pullable manner, and a dust inlet is formed in the top of the dust collection box.

[0017] A first strip hole is formed in the bottom of the moving horizontal plate, and a second strip hole is formed in the bottom of the limiting outer frame.

[0018] The intercepted dust falls into the dust collection box through the second strip hole, the first strip hole and the dust inlet in sequence.

[0019] In a possible design, a transparent window is arranged on one side of the dust collection box, which is used for observing the internal dust accumulation.

[0020] In a possible design, support legs are fixedly installed at the four corners of the bottom of the sample cabinet main body.

[0021] In use, the device realizes the ventilation effect through the first ventilation holes on the two sides, and the air convection can improve the ventilation effect.

[0022] And in order to adjust the effect of external interception of impurities according to the actual situation, at this time the filter plate can be pulled transversely inside the limiting outer frame through the connecting strip, the aperture of the filter plate and the first vent hole appears staggered, thereby the interception effect and ventilation effect can be changed, after adjustment, the rotating clamping plate can be rotated on the outer wall of the rotating shaft, at this time the rotating clamping plate is clamped into the corresponding clamping groove;

[0023] Normally, in the case of opening the cabinet door, the first filter screen can be cleaned and replaced after the annular gland and fixing screws are removed, and the transparent window can be used to understand the dust accumulation inside, the dust collection box can be transversely moved into the containing cavity, and then the dust collection box is pulled out, the moving transverse plate falls, and the limiting outer frame is not limited in the moving transverse plate and the fixed transverse plate, at this time the limiting outer frame can be taken out, and the filter plate and the second filter screen inside can be cleaned.

[0024] Beneficial effects: through the double filtering design of the first filter screen and the second filter screen, dust and other impurities in the air are effectively intercepted, ensuring that the air entering the sample cabinet is clean. At the same time, the adjustable design of the filter plate allows users to adjust the ventilation volume and filtering precision according to actual needs, further improving the dustproof effect.

[0025] The first vent hole and the second vent assembly on both sides of the sample cabinet body form a convection ventilation path, ensuring the air circulation inside the sample cabinet, effectively preventing the problem of sample deterioration or equipment failure caused by air not circulating.

[0026] Each component adopts a modular design, which is convenient for disassembly and cleaning. For example, the first filter screen is fixed in the inner side of the cabinet door through the annular gland and the fixing screws, which is convenient for users to replace or clean. The design of the dust collection box also makes the cleaning of dust simple and fast.

[0027] The support legs installed at the four corners of the bottom of the sample cabinet body ensure the stability of the entire structure. At the same time, the fixed transverse plate and the moving transverse plate in the second ventilation assembly fix the limiting outer frame through clamping, which not only ensures the stability of the structure, but also facilitates the disassembly and assembly of the limiting outer frame.
