The supporting structure includes an oblique support rod 8, and one end of the oblique support rod 8 is hinged to the base 1. A connecting hole is set at the other end of the oblique support rod 8, and a connecting seat 9 is fixedly set on the bottom surface of the side panel 3, and a through hole is set on the connecting seat 9. The connecting hole and the through hole are connected by a pin. The pin passes through the connecting hole and the through hole to support the side panel 3 horizontally on the base 1, and the upper surface of the side panel 3 in a horizontal state is on the same horizontal plane as the upper surface of the base 1. The side plate 3 is provided with a second guide rail 4. When the side plate 3 is in a horizontal state, the second guide rail 4 is located on the same straight line as the first guide rail 2. The second guide rail 4 is used to extend the second guide rail 4.

[0025] The base 1 is provided with a sliding mechanism for driving the purification box 5 to slide inside the first guide rail 2 and the second guide rail 4. The sliding mechanism includes two sliding units arranged symmetrically. The sliding unit includes two cross-arranged first connecting rods 11, and the middle part of each of the first connecting rods 11 is fixedly provided with a first sleeve 14, and the first support rod 16 is rotatably arranged in the first sleeve 14 through a bearing.

A first filter screen 24 and a second filter screen 26 are provided on both sides of the activated carbon frame 25, respectively. The aperture of the first filter screen 24 is not larger than the aperture of the second filter screen 26. The first filter screen and the second filter screen are both fixedly connected to the inside of the purification box 5. The first filter screen 24 is located between the draft fan 23 and the activated carbon frame 25, and is used to filter dust in the air. After being adsorbed by the activated carbon frame 25, the air is sent out of the purification box 5 through the second filter screen to achieve purification of the air.

[0034] When in use, the side plate 3 is supported in a horizontal state by the diagonal support rod 8, and the first guide rail 2 is aligned with the second guide rail 4. The bidirectional screw rod 6 is rotated by the crank 10, and the bidirectional screw rod 6 drives the slide seat 13 to slide relative to each other, and the slide seat 13 drives the first connecting rod 11 and the second connecting rod 12 to rotate, thereby driving the slider 18 to slide in the first slide rail and the second slide rail, and the slider 18 drives the first support rod 16 and the second support rod 17 to slide, and the first gear on the first support rod 16 is meshed with the first rack 19, and the second gear 21 on the second support rod 17 is meshed with the second rack 20, so as to realize the rotation of the first support rod 16 and the second support rod 17, adjust the purification box 5 to the same straight line, and start the induced draft fan 23 to treat the formaldehyde in the air.

[0035] After use, the bidirectional screw rod 6 is rotated in the opposite direction by the crank 10, the slide 13 moves away from each other, the slider 18 slides in the opposite direction in the first guide rail 2 and the second guide rail 4, the first gear and the second gear 21 respectively drive the first support rod 16 and the second support rod 17 to rotate, and the purification box 5 is adjusted to a parallel state, and the bidirectional screw rod 6 is continued to be rotated, and the purification box 5 is folded together in parallel.
