The conductive rod 251 is connected to the negative ion generator 250, and is disposed in the gas flow path between the third inlet 233 and the third outlet 243.

Thus, when the air flow flows from the third inlet 233 to the third outlet 243, it is possible to pass through the conductive rod 251 and to sediment the particles by the negative ions. Optionally, the negative ion generator 250 is disposed proximate to the third outlet 243. Thus, a certain blocking effect is generated on the airflow, and particles in the airflow collide with the negative ion generator 250 and adhere to the surface of the negative ion generator 250.

Optionally, the conductive rod 251 extends from the third outlet 243 in the direction of the third inlet 233. When the gas flows in the gas flow path between the third inlet 233 and the third outlet 243, the gas flows with the conductive rod 251 for a longer time, which is advantageous for settling the particles. Optionally, the third inlet 233 is provided with an inlet end cap 234, the inlet end cap 234 is provided with a bracket 235, and the bracket 235 is connected to the conductive rod 251.

In this way, the negative ion generator 250 is firmly stabilized.

In some embodiments, as shown in connection with fig. 1, the air purifier further includes a centrifugal fan 30. The centrifugal fan 30 is disposed in the second space 11 between the casing 21 and the housing 10, and the air intake side is disposed corresponding to the air flow outlet of the purifying device 20.

The centrifugal fan 30 can drive the airflow to flow, and the centrifugal fan 30 is disposed in the second space 11, and the air intake side is disposed corresponding to the airflow outlet of the purifying device 20, so that the airflow purified by the purifying device 20 can be continuously conveyed, for example, to the outside of the air purifier. The centrifugal fan 30 accelerates the incoming gas by rotation of the impeller, decelerates and changes the flow direction, changes the radial direction when the gas flows through the impeller, and then sends the gas out from the outer peripheral ring of the impeller.

In some embodiments, as shown in connection with fig. 2, the casing 10 is provided with an air outlet 12, and the air outlet 12 is disposed corresponding to the outer circumference of the centrifugal fan 30. The air outlet 12 is arranged at the position corresponding to the outer periphery of the centrifugal fan 30 of the shell 10, so that the air flow discharged by the centrifugal fan 30 can flow out of the air purifier in the original direction, and the air supply intensity can be kept. In addition, the air outlets 12 are circumferentially distributed on the housing 10, so that purified air can flow into the room along all directions, and the air updating efficiency can be improved.

Alternatively, the housing 10 includes a cylindrical side wall and end caps provided at both ends of the cylindrical side wall, and the air inlet 13 is provided at the cylindrical side wall. The air inlet 13 is arranged on the cylindrical side wall, and compared with the air inlet arranged on the end cover, the air inlet 13 can have a larger air inlet area, so that the air inflow of the air purifier is improved. Optionally, the air inlet 13 is arranged along the circumference of the cylindrical sidewall. Through the air inlet 13, the air flow can enter the inside of the housing 10 from all directions, and the air inflow of the air purifier is lifted.

In some embodiments, as shown in connection with fig. 1 and 5, the air purifier further includes a mounting bracket 40. The fixing base 40 is disposed between the centrifugal fan 30 and the purifying device 20, and is provided with a passage for the air flow to pass through, and configured to fix the purifying device 20. The fixing base 40 is fixed in the shell 10 of the air purifier, and the purifying device 20 is fixed on the fixing base 40 and is firm and stable. The holder 40 is between the centrifugal fan 30 and the purification apparatus 20, and air flow can flow from the purification apparatus 20 to the centrifugal fan 30 through the passage, and thus be discharged out of the air purifier. Optionally, the channels are arranged in correspondence of the second end face 213 of the purification device 20. The second end face 213 is provided with an air flow outlet for facilitating the flow of air from the interior of the purification apparatus 20 into the passage.

Alternatively, as shown in connection with fig. 1, the fixing seat 40 partitions the second space 11 into a purifying space in which the purifying device 20 is located and an exhaust space in which the centrifugal fan 30 is located. The fixing seat 40 not only can fix the purifying device 20, but also can divide the second space 11, different functions are realized in different spaces, the internal structure of the air purifier is compact and reasonable, and the volume of the air purifier is reduced.

Alternatively, as shown in fig. 1 and 2, the air inlet 13 is disposed on a side wall of the housing 10 corresponding to the purifying space, and the air outlet 12 is disposed on a side wall of the housing 10 corresponding to the exhausting space. In this way, the air flow enters the purifying space from the air inlet 13, then enters the purifying device 20, after being purified by the purifying device 20, flows into the exhaust space through the channel of the fixing seat 40, and is discharged from the air outlet 12 of the exhaust space under the driving of the centrifugal fan 30. When the centrifugal fan 30 is operated in the exhaust space, a negative pressure region is formed in the purifying space, and the air purifier is further caused to suck in external air from the air inlet 13.

Optionally, the volume of the purge space is greater than the volume of the exhaust space. Since the air flow enters the purifying space and then enters the purifying device 20 with smaller volume, the air flow is affected by a certain wind resistance of the purifying device 20. The volume of the purification space is increased so that the air flow which has not yet entered the purification device 20 can slightly stay in the purification space and then enter the purification device 20. The purified air flow can be directly discharged by a centrifugal fan, and the exhaust space does not occupy too large volume.

Optionally, as shown in fig. 3, the second end surface 213 is provided with a clamping piece 2130, and the clamping piece 2130 is clamped with the fixing base 40. The fixing of the purification apparatus 20 on the fixing base 40 is achieved by the clamping of the clamping piece 2130 and the fixing base 40.

In some embodiments, as shown in connection with fig. 1, 5, the channels include a first channel 401 and a second channel 402. The first channel 401 communicates with the air outlet and the air inlet side of the centrifugal fan 30; the second passage 402 communicates with the second space 11 and the air intake side of the centrifugal fan 30.

The air flow purified by the purifying device 20 can be discharged out of the air purifier through the first channel 401 under the driving of the centrifugal fan 30; the air stream that has not been purified by the purification apparatus 20 may exit the air purifier through the second passage 402. Although part of the air in the second space 11 is discharged without being purified, the resistance of the purifying device 20 to the air flow can be reduced, so that a large amount of air can smoothly enter and exit the air purifier, and the air is gradually purified in the continuous circulating inflow and outflow process of the air.

Alternatively, the second channel 402 is provided at the outer periphery of the first channel 401. In this way, the first channel 401 and the second channel 402 are distributed on the fixing base 40 reasonably, so that the air flow in the second space 11 can flow from the outer circumference of the purifying device 20 to the exhaust space.

Optionally, as shown in fig. 6, the air purifier further includes a filter screen 50, where the filter screen 50 is disposed inside the air inlet 13 of the air purifier. Thus, when the air flow enters the air purifier from the air inlet 13, the filter screen 50 can intercept larger particles such as dust in the air flow, and primarily purify the air flow. Optionally, the filter screen 50 is accordion pleated. Thus, when the airflow passes through the filter screen 50, the contact area between the airflow and the filter screen 50 can be increased, so that particles in the airflow are easy to strike on the surface of the filter screen 50, and the filtering effect is improved.
