Description

Absorbent box structure

The invention relates to an absorbent box structure, in particular to an absorbent box structure which can quickly dry and reduce the moisture absorption material and effectively improve the moisture absorption effect.

According to the humid climate, it is an island-type national climate. Living in a humid environment, in addition to unfavorable clothing, furniture, etc., it also has a negative impact on human health, so the relevant dehumidification products will also be born. Among the dehumidification products sold in the market, chemical substances such as calcium chloride are most popular as the contents, and the storage box is divided into upper and lower two-layer accommodation space, and the upper storage space is arranged. The granular calcium chloride is discharged, and the lower layer collects the dehumidified water vapor liquid. Since the liquid contained therein contains the chemical substance of calcium chloride, if it is accidentally poured into contact with the surrounding articles, it is quite difficult to remove. And if the human body contact causes skin redness, swelling, pain and other inflammatory phenomena, it is also very difficult to recycle. Most users generally pour the liquid containing calcium chloride into the drainage system, and discard the containing box. In addition to causing serious pollution to the environment, it also causes waste of resources.

Therefore, another manufacturer has recently developed a reusable dehumidification product, which mainly has a box-shaped body, and an electric heating component is installed in the box-like body, and a plurality of moisture-absorbing materials are loaded in the box-shaped body. In order to adsorb moisture in the air, when the moisture absorption material absorbs the moisture, the electricity is supplied to the electric heating component, so that the electric heating component converts the electric energy into heat energy, and then the moisture absorption material that has absorbed the moisture is dried. Those who achieve the purpose of reuse. However, although the dehumidification product has the effect of repeating dehumidification, the electric heating component assembled in the body body causes the manufacturing cost of the dehumidification product to be improved, and when the electric heating component is assembled in the body, the inside of the body can be The space for accommodating the moisture absorbing material is relatively reduced, so that the dehumidification product has a limited amount of dehumidification, and the electric heating component is frequently activated to perform the action of drying and dehumidifying the moisture absorbing material, so that the use is inconvenient. After the other part of the electric heating component emits heat energy, its main drying range is its surrounding moisture absorbing material, and it is difficult to fully diffuse all the moisture absorbing materials inside the body. If all the moisture absorbing materials inside the body are to be dried, the electric heating is extended. The component is activated, so when the electric heating component is frequently started and the operating time is prolonged, the required power consumption cost is relatively increased. At the same time, the service life of the electric heating component is relatively shortened, and after a period of use, repair or replacement is required. Causes the user's economic burden.
