[0033] The embodiments of the present utility model will be further described below with reference to the accompanying drawings.

[0034] According to some embodiments of the present utility model, with reference to Figures 1 to 4, the air deodorizer includes a body 100, a filter assembly 300 and a fan assembly 310. An air inlet area 110, a purification area 120 and an air extraction area 130 are provided inside the body 100. The air extraction area 130 is located above the air inlet area 110 and the purification area 120. The purification area 120 is respectively communicated with the air extraction area 130 and the air inlet area 110. The body 100 is provided with an air outlet hole 133 communicated with the air extraction area 130, and the body 100 is provided with a first air inlet hole 131 and a second air inlet hole 132 communicated with the air inlet area 110. An adjusting plate 230 is provided inside the body 100, and the adjusting plate 230 is used to open or close the first air inlet hole 131. The second air inlet hole 132 can be detachably connected to an air extraction pipe 140 or a cover plate 150. When the second air inlet hole 132 is connected to the air extraction pipe 140, the air extraction pipe 140 can suck external gas into the air inlet area 110; when the second air inlet hole 132 is connected to the cover plate 150, the cover plate 150 blocks the second air inlet hole 132; the filter assembly 300 is arranged in the purification area 120, and the filter assembly 300 is used to purify gas. The filter assembly 300 is an activated carbon filter net 141, and the activated carbon filter net 141 can purify gas and remove odor. The fan assembly 310 is arranged in the air extraction area 130, and the air inlet end of the fan assembly 310 faces the purification area 120.

[0035] Referring to Figure 1 and Figure 2 , when the second air inlet hole 132 is connected to the air extraction pipe 140 and the adjusting plate 230 closes the first air inlet hole 131, after the fan assembly 310 is turned on, the gas enters the air inlet area 110, the purification area 120 and the air extraction area 130 in sequence through the air extraction pipe 140. When the gas is in the purification area 120, it is purified and deodorized by the filter assembly 300. When the gas reaches the air extraction area 130, it is then discharged through the air outlet hole 133. The suction end of the air extraction pipe 140 can be moved to a designated position at any time to avoid the need to move the body 100, and it can adapt to various environments. For example, when a 3D printer is working, there is a transparent cover covering the 3D printer, and peculiar smell is generated inside. Usually, the cover needs to be opened to let the peculiar smell disperse, but this will pollute the surrounding environment. However, the air deodorizer of this embodiment can insert the suction end of the air extraction pipe 140 into the transparent cover without removing the transparent cover, avoiding the dispersion of the peculiar smell gas inside. Or, when the space is limited and it is not convenient to move the air deodorizer, only the suction end of the air extraction pipe 140 needs to be close to the source of the peculiar smell, without moving the entire air deodorizer. Or, when the source of the peculiar smell is located in a narrow area, the air extraction pipe 140 is also convenient to penetrate into the narrow area to extract gas.

[0036] Referring to Figure 3 and Figure 4When the second air inlet 132 is connected to the cover plate 150 and the adjustment plate 230 opens the first air inlet 131, the cover plate 150 blocks the second air inlet 132. After the fan assembly 310 is turned on, the gas enters the air inlet area 110, the purification area 120 and the exhaust area 130 in sequence through the first air inlet 131. When the gas is in the purification area 120, it is purified and deodorized by the filter assembly 300. The gas reaches the exhaust area 130 and is then discharged through the air outlet 133. In this state, the air deodorizer can purify the surrounding air.

[0037] According to some embodiments of the present utility model, referring to Figures 1 to 4 , the machine body 100 includes a first shell 210 and a second shell 220, the first shell 210 is located above the second shell 220, the first shell 210 and the second shell 220 are detachably connected, the inner cavity of the first shell 210 is the exhaust area 130, and the second shell 220 is provided with an annular baffle 221, which separates the inner cavity of the second shell 220 into a purification area 120 and an air inlet area 110. The area between the outer wall of the annular baffle 221 and the inner wall of the second shell 220 constitutes the air inlet area 110, and the inner cavity of the annular baffle 221 constitutes the purification area 120, and the air inlet area 110 is annular and surrounds the purification area 120. The upper end of the annular baffle 221 is connected to the top wall of the second shell 220, and there is a gap between the lower end of the annular baffle 221 and the bottom of the second shell 220. The gas can enter the purification area 120 from the air inlet area 110 through the gap. The upper end of the air inlet area 110 is connected to the outside through the first air inlet hole 131.

When the adjusting plate 230 rotates to block the first air inlet holes 131 with the blocking hole strips 231, all the first air inlet holes 131 are blocked. When the adjusting plate 230 rotates to stagger the blocking hole strips 231 from the first air inlet holes 131, external gas can pass through the first air inlet holes 131 and then enter the air inlet area 110 downward through the gaps between two adjacent blocking hole strips 231.

[0040] According to some embodiments of the present invention, referring to Figure 2 , a filter screen 141 is provided in the air extraction pipe 140. The filter screen 141 can filter solid impurities to prevent impurities from entering the interior of the machine body 100 and damaging the machine body 100.

The flow dividing plate 160 is annular, and the flow dividing plate 160 is provided with a plurality of flow dividing holes 161 that are circumferentially distributed along the axis of the flow dividing plate 160. When the gas enters the air inlet area 110 downward from the first air inlet holes 131, the flow dividing plate 160 can further divide the gas. The gas is divided through the plurality of flow dividing holes 161 and then moves downward to ensure that the gas can enter the purification area 120 evenly, improving the purification effect.

[0042] Further, in this embodiment, the second air inlet hole 132 is located below the flow dividing plate 160.
