The blowing device 42 provides power to blow air into the air inlet 43, and the cross-sectional area perpendicular to the axis of the flow channel 41 in the flow channel 41 is gradually reduced from the air inlet 43 to the air outlet 44, so that the air flowing space in the flow channel 41 is gradually reduced, the air is gradually accelerated, and the air carrying negative ions is quickly spread to a longer distance, so that the action range of the purifier is enlarged, and the effect is better; at least one guide plate 45 is arranged in the flow channel 41, so that on one hand, the function of reinforcing ribs is achieved, the structure of the flow channel 41 is more stable, on the other hand, the air in the flow channel 41 is divided by the guide plate 45, and the function of guiding the air flowing in the flow channel 41 is achieved.

In a preferred embodiment, in addition to the above, the baffle 45 is perpendicular to a tangential plane where it meets the flow channel 41.

The guide plate 45 is perpendicular to the tangent plane at the joint of the guide plate 45 and the flow channel 41, so that the included angle formed by the two sides of the flow channel 41 and the guide plate 45 is consistent, when air enters the air outlet part 44 from the air inlet part 43, the guide plate 45 divides the air in the flow channel 41, and the air divided by the guide plate 45 is more uniform.

In a preferred embodiment, in addition to the above-mentioned embodiment, in a direction perpendicular to the axis of the flow channel 41, the farthest position on the baffle 45 is spaced from the flow channel 41 by the width of the baffle 45, and the width of the baffle 45 gradually increases from the air inlet portion 43 to the air outlet portion 44. Because the guide plate 45 has a certain thickness, when air enters the air outlet part 44 from the air inlet part 43, the guide plate 45 with a certain thickness blocks the flow of the air, the width of the guide plate 45 is gradually increased from the air inlet part 43 to the air outlet part 44, so that the windward side of the guide plate 45 is a slope, the blocking effect of the guide plate 45 on the air flow is reduced, and the acceleration effect of the air after passing through the flow channel 41 is facilitated.
