Non-magnetic moisture-proof cabinet

Abstract

The invention relates to a non-magnetic moisture-proof cabinet which comprises a cabinet body and a cabinet door. A humidity control main unit and a control panel connected with the humidity control main unit are installed in the cabinet body; the humidity control main unit consists of two valves, a humidity absorbing module and a shape memory alloy spring, the humidity absorbing module is placed between the two valves, and the two valves are connected via the shape memory alloy spring; a heating ring is sleeved on the shape memory alloy spring; a metal shielding case wraps the outside of the cabinet body and is formed by enclosing an upper cover, a left cover, a right cover, a rear cover and a front cover; and one side of the front cover is abutted to the right cover, the other side of the front cover is hinged with the left cover, and the top of the front cover is connected with a pneumatic device. The humidity control range of the non-magnetic moisture-proof cabinet is 20-60%RH (relative humidity). The non-magnetic moisture-proof cabinet is not affected by external temperature difference, is power-saving and silent, is not made of consumables, and meets requirements on energy conservation and environments, a molecular sieve can be recycled, energy is saved, production cost is reduced, and the problem that stored articles are magnetized due to interference of an external magnetic field can be avoided by the shielding case.

Description

technical field [0001] The invention relates to a moisture-proof cabinet, in particular to a non-magnetic moisture-proof cabinet. Background technique [0002] With the increase of the types of daily necessities, people gradually pay more attention to the preservation of items. However, according to research, when the temperature is above 20°C and the humidity is above 60%RH, all kinds of items will be moldy or damp, resulting in the damage of many important valuable items such as precision electronic instruments, optical equipment, calligraphy and paintings, and confidential documents. This phenomenon is more serious when used, especially in island-type climate environments. Although there are various moisture-proof boxes, dehumidification rods, dehumidifiers, etc. on the existing market, the following defects still exist: 1. The desiccant needs to be replaced continuously, which not only wastes a lot of resources, but also increases the production cost of the enterpri...

Problems solved by technology

However, according to research, when the temperature is above 20°C and the humidity is above 60%RH, all kinds of items will be moldy or damp, resulting in the damage of many important valuable items such as precision electronic instruments, optical equipment, calligraphy and paintings, and confidential documents. This phenomenon is more serious when using, especially in the environment of island climate

Although there are various moisture-proof boxes, dehumidification rods, dehumidifiers, etc. on the existing market, the following defects still exist: 1. The desiccant needs to be replaced continuously, which not only wastes a lot of resources, but also increases the production cost of the enterprise , and sometimes miss the deadline for replacing the desiccant. At this time, the items to be preserved have already deteriorated or moldy, which affects the quality of the preserved items; The quantity will not only increase the cost, but also occupy the space in the cabinet; 3. It is only suitable for placing and collecting general items, and cannot shield the magnetic field. The magnetization effect is large, it is not suitable for the storage of items that require magnetic protection, and the scope of application is limited
