The connection pipe 222 is connected to the discharge ion tube 220 from the first inlet 231, so that the high voltage pack 221 can provide high voltage power to the discharge ion tube 220. By providing the second inlet 232, the flow rate of the gas entering the interior of the housing 21 can be increased, and even if the gas flow entering from the second inlet 232 does not flow through the discharge ion tube 220, the gas flow can be purified by providing other purification components in the housing 21. Also, the second inlet 232 raises the amount of intake air of the purification apparatus 20, and can reduce the wind resistance of the purification apparatus 20 to the airflow entering from the casing 10.

The second outlet is disposed opposite to the second inlet 232, so that the gas can flow between the second outlet and the second inlet 232 to form a gas passage.

In some embodiments, as shown in connection with fig. 1, 3, 4, a first space 26 is formed between the discharge ion tube 220 and the enclosure 21; the airflow inlet 23 further comprises a third inlet 233, the airflow outlet further comprises a third outlet 243, and the third inlet 233 and the third outlet 243 communicate with the first space 26. The air flows into the first space 26 from the third inlet 233 and then flows out from the third outlet 243, and an air passage is formed between the third inlet 233 and the third outlet 243, thereby increasing the intake amount of the purifying device 20, reducing the wind resistance formed inside the air purifier by the purifying device 20, and facilitating the smooth flow of the air stream of the air purifier.

Optionally, the purification apparatus 20 further comprises a control board 27, and the control board 27 is disposed in the first space 26. The air is purified by the negative ion module 25 and the high-voltage ion module 22 through the control board 27. Optionally, the control board 27 is disposed below the high voltage packet 221.

In some embodiments, the purification apparatus 20 further comprises a negative ion module 25. The anion module 25 is disposed within the first space 26 and is configured to agglomerate particles in the settled gas stream.

The negative ion module 25 can generate negative ions, and particulate matters such as PM2.5 with positive potential can be condensed into large particles to be settled due to the negative potential of the negative ion module. The first space 26 is provided with an anion module 25 which can condense and settle particles in the air, so that the particles can be separated from the air. The air flow enters the first space 26 through the third inlet 233, is purified by the negative ion module 25, and then flows out from the third outlet 243. With this embodiment, the air flow entering the purification device 20 is partly passed through the discharge ion tube 220 for sterilization and is partly passed through the first space 26 for sedimentation purification. When the amount of intake air of the purifier 20 is increased, the wind resistance of the purifier 20 to the airflow in the casing 10 is also reduced, the airflow can smoothly flow into and out of the purifier 20, and the air purification and sterilization effects are generated. Even if the air flow entering the purifying device 20 cannot simultaneously perform the purifying and sterilizing functions, the degree of cleanliness of the air can be gradually improved as the air is continuously circulated into the air purifier.

Thus, when the gas flows from the third inlet 233 to the third outlet 243, the gas passes through the conductive rod 251, and the particles are settled by the negative ions. Optionally, a negative ion generator 250 is disposed adjacent to the third outlet 243. Thus, a certain blocking effect is generated on the airflow, and the particles in the airflow collide with the negative ion generator 250 and adhere to the surface of the negative ion generator 250. Optionally, a dust collecting groove is formed on the surface of the negative ion generator 250. The dust collecting groove collects settled particles, and is convenient for centralized cleaning.

Optionally, the conductive rod 251 extends from the third outlet 243 in the direction of the third inlet 233. The gas flow, when flowing in the gas flow path between the third inlet 233 and the third outlet 243, has a longer interaction time with the conductive rod 251, which is beneficial for the settling of the particles. Optionally, the third inlet 233 is provided with an inlet cover 234, the inlet cover 234 is provided with a bracket 235, and the bracket 235 is connected with the conductive rod 251. Thus, one end of the conductive rod 251 can be fixed through the support 235, so that the conductive rod 251 is firmer and more stable, and the conductive rod 251 is prevented from shaking unstably due to the impact of airflow. Optionally, the bracket 235 is provided with a mounting groove into which the conductive rod 251 extends. The current-conducting rod 251 extends into the mounting groove, and the fixing of the current-conducting rod 251 is facilitated. Optionally, a negative ion generator 250 is fixed within the first space 26. Thus, 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 housing 21 and the casing 10, and the air intake side is disposed corresponding to the air outlet of the purifying device 20.

The centrifugal fan 30 can drive the air flow, the centrifugal fan 30 is arranged in the second space 11, the air inlet side is arranged corresponding to the air outlet of the purifying device 20, and the air flow 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 gas introduced by the rotation of the impeller, then decelerates, changes the flow direction so that the gas changes to a radial direction while passing through the impeller, and then is discharged from the outer circumference of the impeller.

In some embodiments, as shown in fig. 2, the housing 10 is provided with an air outlet 12, and the air outlet 12 is disposed corresponding to an outer periphery of the centrifugal fan 30. The casing 10 is provided with the air outlet 12 at a position corresponding to the outer circumference of the centrifugal fan 30, so that the air flow discharged from the centrifugal fan 30 can conveniently 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 distributed in the circumferential direction of the housing 10, so that the purified air can flow into the room along various directions, which is beneficial to improving the air renewal efficiency.

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. Air intake 13 sets up in the cylindric lateral wall, compares and sets up in the end cover, can possess bigger air inlet area, promotes air purifier's air input. Alternatively, the air inlet 13 is provided along the circumferential direction of the cylindrical side wall. The air inlet 13 allows air flow to enter the interior of the housing 10 from various directions, thereby increasing the air intake of the air cleaner.

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

Alternatively, as shown in fig. 1, the fixing base 40 divides the second space 11 into a purification space where the purification apparatus 20 is located and an exhaust space where the centrifugal fan 30 is located. Fixing base 40 not only can fix purifier 20, can also separate the division to second space 11, and different functions are realized to different spaces, make air purifier inner structure compact reasonable, are favorable to reducing air purifier's volume.

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 purification space, and the air outlet 12 is disposed on a side wall of the housing 10 corresponding to the exhaust space. Thus, the air flow enters the purifying space from the air inlet 13, then enters the purifying device 20, and after being purified by the purifying device 20, flows into the exhaust space through the channel of the fixing base 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 operates in the exhaust space, a negative pressure region is formed in the cleaning space, and thus the air cleaner sucks external air from the air inlet 13.

Optionally, the volume of the purification space is larger 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, it will be affected by the wind resistance of the purifying device 20. The volume of the purification space is increased so that the gas flow which has not entered the purification apparatus 20 can stay a little in the purification space and then enter the purification apparatus 20. The purified air flow can be directly discharged by a centrifugal fan, and the exhaust space does not need to occupy too large volume.

Optionally, as shown in fig. 3, a clip 2130 is disposed on the second end surface 213, and the clip 2130 is engaged with the fixing base 40. The fixing of the purification device 20 on the fixing seat 40 is realized by the clamping of the clamping piece 2130 and the fixing seat 40.

In some embodiments, as shown in connection with fig. 1 and 5, the channels include a first channel 401 and a second channel 402. The first channel 401 is communicated 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.

Under the driving 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; the air stream, which is not purified by the purification apparatus 20, may exit the air purifier through the second passage 402. Although the air in the second space 11 is discharged without being purified, the resistance of the air flow generated by the purifying device 20 can be reduced, so that a large amount of air can be smoothly introduced into and discharged from the air purifier, and the air can be gradually purified during the continuous circulation of the air in and out.

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 reasonably distributed on the fixing base 40, so that the air flow in the second space 11 can flow from the outer periphery of the purifying device 20 to the exhaust space.

Optionally, as shown in fig. 6, the air purifier further includes a filter screen 50, and 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, filter screen 50 is accordion-pleated. Therefore, when the air flow passes through the filter screen 50, the contact area between the air flow and the filter screen 50 can be increased, so that particles in the air flow are easy to impact on the surface of the filter screen 50, and the filtering effect is improved.

Optionally, as shown in fig. 5 and 6, the fixing seat 40 is provided with a groove 403, the groove 403 is disposed around the periphery of the channel, and one side of the filter screen 50 can be clamped into the groove 403. Thus, it is convenient to fix the filter net 50 to the inside of the intake port 13. When the filter screen 50 is in an accordion shape, one side of the filter screen 50 is clamped in the groove 403, and the filter screen 50 is not completely attached to the groove 403 but has a gap for collecting dust falling from the filter screen 50. For example, the filter screen 50 is enclosed into a cylinder shape and is vertically arranged, the fixing seat 40 is arranged at the lower part of the filter screen 50, and the lower side of the filter screen 50 is clamped into the groove 403. Thus, particles such as dust caught by the filter net 50 may slide down and enter the groove 403.

Optionally, a groove 403 is provided in the outer periphery of the second channel 402. Thus, the air flow is filtered by the filter net 50 and then flows from the first passage 401 or the second passage 402 to the exhaust space.

Optionally, the shell 10 is provided with a USB interface, and a power board is disposed in the shell 10 and electrically connected to the USB interface. The air purifier is connected with a power supply through a USB interface. The power supply may be a dc power supply.
