Scroll holder with automatic dehumidification mechanism

Abstract

The invention discloses a scroll holder with an automatic dehumidification mechanism. The scroll holder comprises a cylinder (1); a separator (2) is arranged at the bottom of the cylinder (1); a receiving cavity is formed between the separator (2) and the base plate of the cylinder (1); a dehumidification mechanism is arranged in the receiving cavity and comprises a power source (4), a switch (5), a humidity sensor (6), a controller (7), a fan (8) and a rotating vane (9) fixedly connected with the output shaft of the fan (8), wherein the humidity sensor (6) is used for detecting and obtaining a detection signal; the controller (7) obtains a humidity value and compares the humidity value with a preset humidity value; when the humidity value is greater than the humidity value, the controller (7) drives the output shaft of the fan (8) so as to drive the rotating vane (9) to rotate, and then damp air in the cylinder (1) can be sucked from a through hole (3) and discharged from an air outlet (10). The scroll holder with the automatic dehumidification mechanism is capable of realizing storage and dehumidification, and therefore, the utilization efficiency of the scroll holder is improved and the safety of storage and the practicability of the scroll holder are improved.

Description

technical field [0001] The invention relates to a painting cylinder with an automatic dehumidification mechanism, which belongs to the technical field of art supplies. Background technique [0002] In art supplies, painting tube is a common tool for holding paintings. It is composed of a simple cylinder, and the material is usually made of plastic, so that the calligraphy and painting works are rolled up and placed in the cylinder to prevent damage, and realize the storage function of the painting cylinder, which is convenient to place and carry, and can also prevent the calligraphy and painting works from being damaged. Long-term contact with air can achieve the effect of air isolation to a certain extent. Therefore, this kind of simple in structure, light painting cylinder obtains people's favor, is widely used. [0003] Nevertheless, there are still defects in the actual use of the painting tube. A painting tube with such a structure cannot realize classified storage, ...

AI Technical Summary

Problems solved by technology

But despite this, the painting cylinder of this structure cannot better realize the humidity maintenance function after the calligraphy and painting works are put in, and cannot detect the humidity, and cannot further realize the effect of isolating the air of the cylinder.

[0006] Therefore, the traditional cylinder cannot detect the humidity in the cylinder and extract the humidity in the cylinder, and cannot achieve the function of maintaining humidity well. If the humidity is high, it is easy to corrode the calligraphy and painting works and damage the scroll, thus Affected the function of the painting tube
