The ventilated test cabinet can effectively improve the ventilation effect inside the test cabinet through the ventilation mechanism, prevent the items inside the test cabinet from getting damp, and avoid the phenomenon that the items inside the test cabinet become moldy due to moisture, thereby effectively improving the practicality of the test cabinet. The ventilation fan blows air to the inside of the test cabinet to form air convection inside the test cabinet, and cooperates with the ventilation slots opened inside the test cabinet to accelerate the speed of replacing the air inside the test cabinet with the outside air.

[0027] Most test cabinets use a motor to drive a screw rod to move the ventilation fan up and down to ventilate the inside of the test cabinet. However, since there are multiple pallets inside the test cabinet, not only can the ventilation not be performed on each pallet at the same time, which reduces the ventilation effect, but also requires an increase in the power supply used by the motor, which increases the cost of using the test cabinet, causing economic losses, thereby reducing the practicality of the test cabinet.

[0028] See also Figure 1-Figure 5 The embodiment of the utility model shown in the figure comprises a laboratory cabinet body 10, a plurality of pads 11 are arranged inside the laboratory cabinet body 10, and a plurality of support plates 12 are snap-fitted to the upper surfaces of the plurality of pads 11 through a snap-fit ​​assembly 13; a filter assembly 20 for filtering dust and other impurities in the air is arranged at the lower part of the interior of the laboratory cabinet body 10, a ventilation assembly 30 for ventilating the laboratory cabinet body 10 is arranged on the back of the laboratory cabinet body 10, and a plurality of ventilation openings 14 are provided on both sides of the laboratory cabinet body 10.

[0029] First, the specific structure of the snap-in assembly 13 is disclosed. The snap-in assembly 13 at least includes a snap slot 131 and a snap buckle 132 . The snap slot 131 is provided at the bottom of the support plate 12 , and the snap buckle 132 for snapping with the snap slot 131 is provided on the upper surface of the pad 11 .

[0030] The improvement lies in: placing the support plate 12 on the upper surface of the pad 11, and then pressing the support plate 12 downward so that the buckle 132 is engaged with the slot 131. This is not only convenient for installation and disassembly, saving time and effort, but also convenient for the subsequent cleaning of the support plate 12, ensuring the cleanliness of the experimental environment, increasing the cleanliness of the experimental cabinet, and also protecting the experimental objects, thereby improving the practicality of the experimental cabinet.

[0031] Secondly, the specific structure of the filter assembly 20 is disclosed. The filter assembly 20 at least includes a mounting groove 21. The bottom of the interior of the experimental cabinet body 10 is provided with a mounting groove 21. A filter 22 is arranged inside the mounting groove 21. A mesh plate 23 is arranged at the opening above the filter 22. The mesh plate 23 is made of metal.

[0032] The improvement lies in that: by connecting the filter 22 to a power source and making it work, the dust and other impurities in the air inside the laboratory cabinet body 10 can be filtered, the cleanliness of the experimental environment is ensured, the accuracy of the use of the laboratory cabinet is improved, and thus the practicality of the laboratory cabinet is improved.

[0033] The specific structure of the ventilation component 30 is disclosed again. The ventilation component 30 at least includes an installation box 31. The installation box 31 is arranged on the back side of the laboratory cabinet body 10. A ventilation fan 32 is arranged inside the installation box 31. An air distribution plate 33 is arranged at the air outlet of the ventilation fan 32. A plurality of air outlet plates 34 are arranged on the side of the air distribution plate 33 away from the ventilation fan 32. The air outlets of the plurality of air outlet plates 34 are located inside the laboratory cabinet body 10.

[0034] The improvement lies in that: a plurality of air outlet plates 34 are respectively used to position the space between each support plate 12, and the ventilation fan 32 is powered on to make it work. The wind blown out by the ventilation fan 32 is diverted to each air outlet plate 34 through the air distribution plate 33, and then flows to the space separated by each support plate 12 through the plurality of air outlet plates 34, so that the interior of the experimental cabinet body 10 is ventilated at the same time, which not only improves the ventilation effect, but also reduces the consumption of electric energy, avoids economic losses, and thus improves the use effect of the experimental cabinet.

[0035] Considering that the ventilation fan 32 generates heat when working for a long time, which may cause the ventilation fan 32 to malfunction frequently over a long period of time, a plurality of heat dissipation holes 35 are provided in the installation box 31 near the ventilation fan 32 .

[0036] The improvement lies in that the heat generated by the ventilation fan 32 can be dissipated through multiple heat dissipation holes 35, preventing heat accumulation from causing damage to the ventilation fan 32, increasing the service life of the ventilation component 30, thereby reducing the frequency of failure of the laboratory cabinet and avoiding economic losses.

[0037] In summary, the working principle of the present solution is as follows: first, place the support plate 12 on the upper surface of the pad 11, and then press the support plate 12 downward to engage the buckle 132 with the slot 131, and then connect the power supply to the filter 22 to make it work. After that, connect the power supply to the ventilation fan 32 to make it work. The wind blown out by the ventilation fan 32 is diverted to each air outlet plate 34 through the air distribution plate 33, and then flows to the space separated by each support plate 12 through multiple air outlet plates 34, so that the interior of the laboratory cabinet body 10 is ventilated at the same time, and the preparation work before the use of the laboratory cabinet is completed.
