The formaldehyde adsorption assembly 2 is connected above the air outlet 14, and comprises a ring-shaped air guide 21 and a cup-shaped air guide 22 arranged in the ring-shaped air guide 21. The first side wall height of the ring-shaped air guide 21 is greater than the second side wall height of the cup-shaped air guide 22. The guide cover plate 4 comprises a guide plate 43 and a ring-shaped inner wall 41 protruding downward from the guide plate 43. The inner wall of the ring-shaped inner wall 41 forms a emitting port 44. When the guide cover plate 4 is connected to the upper end of the formaldehyde adsorption assembly 2, the ring-shaped inner wall 41 is inserted into the interior of the cup-shaped air guide 22. The ring-shaped air guide 21, the cup-shaped air guide 22 and the ring-shaped inner wall 41 jointly form a filtering pipeline which converges inward and reciprocally bends. Formaldehyde adsorption medium is arranged in the filtering pipeline. After the air flow passes through the adsorption medium in the filtering pipeline, the air flow is emitted from the emitting port 44 along the anti-gravity direction. The lower surface of the guide plate 43 guides the air flow between the ring-shaped air guide 21 and the cup-shaped air guide 22 to flow between the cup-shaped air guide 22 and the ring-shaped inner wall 41. The upper surface of the cup bottom of the cup-shaped air guide 22 guides the air flow between the cup-shaped air guide 22 and the ring-shaped inner wall 41 to flow to the emitting port 44. The formaldehyde adsorption medium comprises a plurality of activated carbon packs which are attached to any position of the inner side of the first side wall of the ring-shaped air guide 21, the two sides of the second side wall of the cup-shaped air guide 22, the two sides of the ring-shaped inner wall 41, the lower surface of the guide plate 43 and the upper surface of the cup bottom of the cup-shaped air guide 22. The fan 12 comprises an impeller with high rotating speed to provide large suction. The adsorption medium is located downstream of the fan 12. External air enters the body 1 vertically upward from the air inlet 11 at the bottom of the body 1. The bottom of the formaldehyde adsorption assembly 2 is provided with a bayonet, which is detachably connected with the clamping groove 13 surrounding the air outlet 14 of the body 1. The present application can set more activated carbon packs by means of the reciprocally bent filtering pipeline, thereby doubling the adsorption capacity.

[0063] In order to further enhance the effect of removing formaldehyde, an upwardly open volatile groove 23 is arranged around the ring-shaped air guide 21. The volatile groove 23 is filled with volatile formaldehyde removal gel. The volatile formaldehyde removal gel is disturbed by the upwardly emitted air flow and volatilizes upwardly. The ring-shaped air guide 21 is a circular pipe. The opening of the volatile groove 23 is a ring-shaped groove body surrounding the upper end of the ring-shaped air guide 21. A ring of air permeable holes 42 is arranged on the guide cover plate 4 outside the ring-shaped inner wall 41. The air permeable holes 42 are communicated with the opening of the volatile groove 23. After the volatile formaldehyde removal gel volatilizes, it passes through the air permeable holes 42 of the guide cover plate 4 and gradually diffuses after continuing to rise with the air flow. Since the air at the upper part of the volatile groove 23 is continuously "sucked" upwardly, the upward volatilization speed of the volatile formaldehyde removal gel in the volatile groove 23 is accelerated by one step. Compared with the existing passive volatilization formaldehyde removal gel, the present application greatly increases the effect of the volatile formaldehyde removal gel contacting with the air in the upper space, thereby improving the formaldehyde removal efficiency.
