In the embodiment of the present invention, as shown in fig. 1 and fig. 2, the air purifier 100 includes a housing 110, two filter screen layers 120, two anion generators 130 and a centrifugal fan 140, the housing 110 is provided with two air inlets 111 and one air outlet 112, the two air inlets 111 are disposed at two opposite sides of the housing 110, the two filter screen layers 120 are both mounted in the housing 110 and are respectively located at the two air inlets 111, the two anion generators 130 are disposed in the housing 110, and one anion generator 130 is disposed near one filter screen layer 120. The centrifugal fan 140 is disposed in the casing 110 and located between the two filter mesh layers 120, two air inlet ends of the centrifugal fan 140 are respectively disposed toward the two filter mesh layers 120, and an air outlet end of the centrifugal fan 140 is disposed toward the air outlet 112.

This centrifugal fan 140 hangs and installs in casing 110, and two air inlet ends of centrifugal fan 140 set up towards two filter screen layers 120 respectively, and two filter screen layers 120 are located two air intakes 111 respectively, and centrifugal fan 140's air inlet end is relative with air intake 111 promptly, and the air inlet angle is zero, and centrifugal fan 140's air-out end sets up towards air outlet 112, has reduced air purifier 100's structural resistance. After entering the air purifier 100 from the air inlet 111, the air is directly filtered by the filter screen layer 120 and discharged by the negative ion generator 130, so that living germs in the air are killed, and the air can be discharged out of the air purifier 100 by the air outlet machine without turning the air flow in the air purifier 100.

According to the technical scheme, two air inlets 111 and one air outlet 112 are formed in two opposite sides of a shell 110, filter screen layers 120 are mounted on the shell 110 at the positions of the two air inlets 111, a centrifugal fan 140 is arranged in the shell 110 and located between the two filter screen layers 120, two air inlet ends of the centrifugal fan 140 are respectively arranged towards the two filter screen layers 120, and an air outlet end of the centrifugal fan 140 is arranged towards the air outlet 112. That is, the air inlet end of the centrifugal fan 140 is opposite to the air inlet 111, the air outlet end of the centrifugal fan 140 is opposite to the air outlet 112, and the negative ion generator 130 is disposed in the housing 110 near the filter screen layer 120. After the air enters the air purifier 100 from the air inlet 111, the air is directly filtered by the filter screen layer 120 and discharged by the negative ion generator 130, so that living germs in the air are killed, the air can be discharged out of the air purifier 100 by the air outlet machine without turning the air flow in the air purifier 100, and the filtering efficiency of the purifier is improved. And the both sides of casing 110 all are equipped with air intake 111, have increased air inlet efficiency, have further improved the filtration efficiency of clarifier.

To further improve the filtering efficiency, in one embodiment, the centrifugal fans 140 are equidistant from the two air inlets 111. That is, the two air inlets 111 are symmetrical with respect to the centrifugal fan 140, and at this time, the negative pressures generated by the centrifugal fan 140 at the air inlets 111 are equal. The time for the airflow to reach the inlet ends of the two centrifugal fans 140 from the two air inlets 111 is equal, so that the flow rates at the two sides are balanced, and the air inlet efficiency is improved.

Further, in one embodiment, the rotational axis 160 of the centrifugal fan 140 passes through the center of the filter mesh layer 120. That is, the rotation axis 160 of the centrifugal fan 140 substantially coincides with the center line of the filter screen layer 120, so that the air at the position with the same distance from the center of the filter screen layer 120 has the same magnitude of negative pressure, thereby making the air intake more balanced and improving the air intake efficiency.

Referring to fig. 1 and fig. 2 in a sub-combination manner, in an embodiment, the housing 110 further includes an air outlet duct 116, one end of the air outlet duct 116 is communicated with the air outlet end of the centrifugal fan 140, and the other end is communicated with the air outlet 112. Specifically, the air outlet duct 116 not only communicates with the air outlet end of the centrifugal fan 140 and the air outlet 112, but also separates the air outlet 112 of the air purifier 100 from other internal spaces of the air purifier 100, so that the filtered air can only flow out from the air outlet duct 116. And at the same time, the centrifugal fan 140 and the housing 110 are fixedly connected, so that the centrifugal fan 140 can be stably fixed inside the air purifier 100.

The air outlet duct 116 may be connected to the air outlet end of the centrifugal fan 140 through a screw. Of course, in other embodiments, the air outlet duct 116 and the air outlet end of the centrifugal fan 140 may be fixed by clamping or welding. The outlet duct 116 may be connected to the housing 110 by screws. Of course, in other embodiments, the air outlet duct 116 and the housing 110 may be fixed by clamping or welding.

In one embodiment, the anion generator 130 is disposed between the centrifugal fan 140 and the filter screen layer 120. When the airflow enters the air inlet 111, the airflow passes through the filter screen layer 120 to filter out impurities in the air, and then passes through the discharge region of the anion generator 130, the anion generator 130 can ionize the air, so that a large amount of anion charges are distributed in the inner space of the air purifier 100, and the anion charges can kill germs in the air. The negative ion generator 130 is arranged between the centrifugal fan 140 and the filter screen layer 120, so that air can enter the negative ion discharge area through the filter screen layer 120, and the germ inactivation efficiency is improved.

In order to better collect the filtered impurities, in an embodiment, a filter cavity 113 and a dust collection cavity 114 which are communicated with each other are arranged at the air inlet 111 of the housing 110, the filter screen layer 120 is installed in the filter cavity 113, and the impurities filtered by the filter screen layer 120 fall into the dust collection cavity 114.
