After the activated carbon 3 in the adsorption cavity 221 communicated with the outside is adsorbed for a period of time (in this embodiment, 15 days), the activated carbon 3 in the adsorption cavity 221 is in a saturated state, the first controller 25 controls the operation of the adsorption cylinder driving part 24 to drive the adsorption cylinder 22 to rotate 90 degrees, so that the adsorption cavity 221 filled with the activated carbon 3 after adsorption saturation is sealed by the flexible waterproof shielding belt 23, and secondary pollution caused by leakage of formaldehyde adsorbed on the activated carbon 3 in the adsorption cavity 221 is prevented; meanwhile, one of the adsorption chambers 221 to be used is rotated to the communication space 232 of the flexible waterproof shielding belt 23 to be exposed to the outside of the air for formaldehyde adsorption. The first controller 25 controls the operation of the adsorption cylinder driving member 24 until the activated carbon 3 in the four adsorption cavities 221 in the adsorption cylinder 22 is in an adsorption saturated state (about 60 days to 120 days), at this time, the first controller 25 controls the alarm 8 to give an alarm to remind a user to take out the formaldehyde adsorption mechanism 2 from the sofa body 1 in time, and the formaldehyde adsorption mechanism is placed outdoors for conducting an explosion and drying or ventilation treatment. When a person is on the sofa body 1 and the pressure sensor 92 detects that the pressure applied to the supporting member 15 is greater than the preset pressure value during the use of the sofa 100, the second controller 93 controls the movable door 9 to rotate to close the opening 14 of the sofa body 1, so as to further prevent the formaldehyde adsorbed in the formaldehyde adsorption mechanism 2 from being released accidentally to affect the health of the person.
When the activated carbon 3 in the adsorption cavity 221 is completely deactivated, the two opposite ends of the flexible waterproof shielding belt 23 can be disconnected through the connecting piece 4, then one end of the fixing shaft 214 is taken out of the supporting plate 213, the fixing shaft 214 is rotated to drive the adsorption cylinder 22 to rotate so that the taking and placing opening of the cylinder 224 faces upwards, the sealing cover 225 is opened, the activated carbon 3 which is deactivated in the adsorption cavity 221 is taken out, and then new activated carbon 3 with activity is put into the adsorption cavity 221 of the adsorption cylinder 22, so that the formaldehyde adsorption mechanism 2 can be reused.

The retainer plate 96 is capable of rotating between a first position and a second position when subjected to an external force. When the retainer plate 96 is located at the first position, the retainer plate 96 extends into the ejection outlet 156 and abuts against the top of the baffle 94, so that the baffle 94 is completely accommodated in the accommodating part 154, and the return spring 95 is compressed under the pressure of the baffle 94; when the retainer plate 96 is in the second position, the retainer plate 96 is located outside the ejection outlet 156 and is out of contact with the top of the shutter 94, and the elastic return action of the return spring 95 causes the shutter 94 to move along the receiving portion 154, so that part of the shutter 94 is ejected from the ejection outlet 156. The portion of the flap 94 that is ejected can act as a stop for a seat cushion placed on the support 15 to prevent the seat cushion from falling. When the cushion is not in use, the baffle 94 is received in the receiving portion 154 and fixed by the stopper plate 96, so that the normal use of the sofa 100 is not affected.
The sofa 100 according to the embodiment of the present invention is provided with the formaldehyde adsorption mechanism 2, so that the purpose of purifying formaldehyde in air can be achieved. A plurality of adsorption cavities 221 are arranged in the adsorption cylinder 22 of the formaldehyde adsorption mechanism 2 at intervals around the central axis of the adsorption cylinder, the adsorption cylinder 22 is matched with the flexible waterproof shielding belt 23, and the adsorption cylinder 22 is rotated to enable the adsorption cavities 221 to be sequentially communicated with the outside for adsorption, so that compared with a carbon bag in the prior art, the formaldehyde adsorption mechanism can prolong the service time of the formaldehyde adsorption mechanism 2, and avoid the trouble of frequently airing activated carbon; and by rotating the adsorption cylinder 22, the adsorption cavity 221 saturated in adsorption can be closed by the flexible waterproof shielding belt 23, so that the possibility of secondary pollution to indoor air caused by the re-release of adsorbed formaldehyde is reduced. Meanwhile, in the sofa 100 of the present invention, the formaldehyde adsorption mechanism 2 is disposed in the sofa body 1, so that the sofa does not occupy the usable floor space in the room, and the space for people to move in the room is not reduced.
It is understood that the number of the adsorption chambers 221 is not limited to the present embodiment, and may be set according to actual needs.
It is to be understood that the structure of the suction cylinder driving member 24 is not limited to this embodiment, and for example, in other embodiments, the suction cylinder 22 may be directly driven to rotate by a motor.
It is understood that the installation manner of the movable door 9 is not limited to the embodiment, for example, in other embodiments, the movable door 9 is slidably installed on the sofa body 1, and the movable door driving member 91 can drive the movable door 9 to slide to open or close the opening 14 of the sofa body 1.
It is to be understood that the sofa 100 is not limited to the wooden sofa in the present embodiment, and may be a cloth sofa or a leather sofa in other embodiments.
It is understood that the structure of the sofa body 1 is not limited to the present embodiment. For example, in other embodiments, the sofa body 1 may not include the armrest 17 or the backrest 16.
The above description is intended to describe in detail the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the claims of the present invention, and all equivalent changes and modifications made within the technical spirit of the present invention should fall within the scope of the claims of the present invention.
