Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of activated carbon adsorption devices, and particularly relates to an activated carbon adsorption device for removing formaldehyde. Background Art
[0002] Activated carbon adsorption devices for removing formaldehyde are usually designed as a structured device, which aims to use the efficient adsorption capacity of activated carbon to capture and reduce the formaldehyde content in the air. This type of device combines the physical adsorption characteristics of activated carbon with specific engineering design to achieve effective improvement of indoor air quality. In the prior art, a carrying box is usually set on a support table, and a ventilation duct runs through the right side of the carrying box. A fan is fixed inside the ventilation duct to introduce air. However, in this method, the fan is fixed and the suction angle of the fan cannot be adjusted. The fixed suction angle of the fan means that the device has poor adaptability to the airflow direction. In actual application environments, indoor air flow conditions may change due to factors such as room layout, personnel activities, and door and window opening positions. The inability to adjust the suction angle may cause the device to be unable to effectively capture formaldehyde released from specific areas or furniture, affecting the purification efficiency.
[0003] For example, the utility model with announcement number CN214182450U discloses an activated carbon adsorption device for removing formaldehyde. In the technical solution of this patent, a carrying box is arranged at the upper end of the support platform, a filter screen is clamped on the left side of the carrying box, and a ventilation duct is arranged on the right side. A fan and a partition screen are fixed in the ventilation duct. However, in this method, the fan is fixed and the suction angle of the fan cannot be adjusted. The indoor formaldehyde distribution may not be uniform. Some corners or confined spaces may have "hot spots" with high formaldehyde concentrations. Fans with fixed suction angles may find it difficult to fully cover these areas, resulting in poor local purification effects and affecting the uniformity of air quality in the entire room. Utility Model Content
[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides an activated carbon adsorption device for removing formaldehyde, which can not only perform a preliminary filtering effect on the air through a mesh plate, intercept large dust particles entering the device, and prevent these larger impurities from directly clogging the activated carbon layer, but also adjust the suction angle of the fan through the suction device, so that the equipment can flexibly adapt to different space layouts, furniture placement and airflow conditions, ensuring the effective capture and treatment of air containing formaldehyde.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] First, by setting up a suction device and starting the telescopic push rod, the support frame can be moved up and down, thereby driving the fan to move up and down. At the same time, starting the motor can rotate the worm, thereby driving the worm gear to rotate.

The easy-to-open design of the box door 102 allows the user to replace the new activated carbon bag 210 in time according to the actual situation and the recommended cycle to ensure continuous and effective formaldehyde removal. Adsorption effect, the interior of the box 101 is evenly provided with a plurality of grooves, the interior of the grooves are all clamped with filter plates 104, a mesh plate 105 is provided on the left side of the box 101, the mesh plate 105 can play a role of preliminary filtering, intercepting large particles of dust, hair, fiber and other larger suspended matter entering the device, preventing these larger impurities from directly clogging the activated carbon layer, thereby extending the service life of the activated carbon and maintaining its adsorption performance, a suction device is provided at the right end of the mesh plate 105, and an air outlet is provided at the right end of the box 101.
