Description

Technical Field

[0001] The utility model relates to the technical field of laboratory cabinets, in particular to a moisture-proof laboratory cabinet. Background Art

[0002] The humidity in the storage space of the experimental instrument has an important impact on the accuracy of the experimental instrument. When the humidity is high, it will cause damage to some precision parts of the experimental instrument. The space in the laboratory is large, and it is costly to maintain the humidity of the entire laboratory within a certain range. Therefore, some special cabinets are often used to store experimental instruments.

[0003] The moisture-proof method of the prior art is to place some desiccants in the cabinet. This method requires timely replacement of the desiccant, which is cumbersome to operate and requires the state of the desiccant to be observed at any time. If the water absorption of the desiccant reaches saturation and is not discovered in time, the moisture in the laboratory cabinet cannot be absorbed in time, which has an adverse effect on the precision components placed in the laboratory cabinet. Therefore, it is necessary to improve this defect.

[0004] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

There is a situation where the water absorption of the desiccant reaches a saturated state and is not discovered in time, resulting in an adverse effect on the precision parts placed in the laboratory cabinet.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A moisture-proof laboratory cabinet comprises a cabinet body, a cabinet door provided at an opening of the cabinet body for sealing the interior of the cabinet body, and further comprising:

[0008] The dehumidification unit includes a support assembly disposed in the cabinet for carrying the experimental instrument, and an exhaust assembly disposed on the upper part of the cabinet for exhausting moisture in the cabinet;

[0009] The heating unit comprises a preheating component arranged at a side of the cabinet body opposite to the exhaust component, and a sealing component arranged at the bottom of the preheating component for sealing the cabinet body and the preheating component after dehumidification.

[0010] Furthermore, the support assembly includes:

[0011] A support frame, which is provided with multiple layers at equal intervals from top to bottom inside the cabinet and is used to support the experimental instruments;

[0012] The vent is provided through the interior of the support frame near one end and is used to transport the gas at the bottom of the cabinet upward.

[0013] Furthermore, the ventilation openings are arranged in opposite directions between upper and lower adjacent support frames.

[0017] A communication hole is provided inside the first fixing block and is coaxial with the air outlet of the air pump;

[0018] A guide groove, provided inside the first fixing block;

[0019] The valve is slidably inserted in the guide groove and is used to block the air outlet of the exhaust pump.

[0020] Furthermore, the preheating component comprises:

[0021] A heat insulation board is arranged inside the cabinet near the side, and a preheating channel is formed between the heat insulation board and the cabinet;

[0022] A first air inlet is provided at an upper portion of one side of the cabinet, and the first air inlet corresponds to the preheating channel;

[0023] A heating block is fixedly connected to one side of the cabinet and is located in the preheating channel, and is used for preheating the air entering from the first air inlet.

[0024] Furthermore, the closure assembly comprises:

[0025] A second air inlet is provided at a lower position inside the heat insulation board and is used to deliver the hot air preheated in the preheating channel into the cabinet;

[0026] The second fixing block is provided with two groups, fixedly connected to one side of the heat insulation board located at the supporting assembly and located above the second air inlet;

[0027] The baffle is rotatably connected between the two groups of the second fixed blocks through an axis, and is used to close the second air inlet after dehumidification.

[0028] Compared with the prior art, the beneficial effects of the utility model are:

The exhaust pump is started, and the exhaust pump discharges the moisture in the cabinet through the connecting hole. During this process, the cabinet is in a negative pressure state, and the baffle rotates around the second fixed block to open the second air inlet. The air outside the cabinet enters the preheating channel through the first air inlet for heating and dehumidification. Subsequently, the dehumidified gas enters the cabinet through the second air inlet, and passes through the ventilation holes from the lower part of the cabinet to the upper part of the cabinet, so that the moisture in the original cabinet is completely replaced by the preheated hot air, thereby achieving dehumidification in the cabinet without the use of a desiccant. The operation is simple, and the moisture in the cabinet can be removed in a timely and comprehensive manner.

[0030] 2. After the dehumidification work is completed, the utility model turns off the start-stop switch of the heating block, turns off the exhaust pump, and pushes the valve along the guide groove to close the connecting hole. At this time, the cabinet is in a normal pressure state, and the baffle rotates around the second fixed block under the action of its own gravity to close the second air inlet, so as to prevent moisture from entering the cabinet after dehumidification again and causing moisture in the cabinet.
