However, since people need to operate the range hood before the range hood, even if the air curtain mechanism 70 is provided, the oil smoke still leaks from the air curtain mechanism 70, and the escaped oil smoke can be completely sucked by the air purification device 50. In addition, an air curtain mechanism 70 may be further provided outside the air purification device 50, so that an air curtain is also formed around the air purification device 50, thereby better removing oil smoke. In addition, the back of the range hood 10 is generally close to a wall, so the air curtain mechanism 70 may be a single piece independently arranged in three directions outside the range hood 10, surround the range hood 10, or form a shape surrounding the range hood 10. The air curtain mechanism 70 may be disposed only at a position facing the user on the front side of the range hood 10, or may surround the range hood 10.

As shown in fig. 3, a three-way valve 30 is disposed on the air outlet 20 of the range hood 10, a first end of the three-way valve 30 is connected to the air outlet 20 and the air outlet housing of the range hood 10, a second end of the three-way valve 30 is communicated with an external flue for discharging the oil smoke generated by the range hood 10 through the flue, a third end of the three-way valve is connected to an air purifying device 50 through a communication pipeline 40, and the three-way valve 30 can switch the oil smoke generated by the range hood 10 to be discharged to the external flue or to be discharged to the air purifying device 50. In order to better remove the oil smoke, other structures such as the oil smoke removing device 60 may be provided in the communication duct 40.

The air purification device 50 includes at least one upward air inlet 11 for connecting with the communication pipeline 40, i.e. connecting with the range hood 10, and includes at least one air inlet 11 communicating with the room and at least one air outlet 12 communicating with the room. The air cleaning apparatus 50 includes a housing 1, and an air cleaning unit 2 provided in the housing 1. The housing 1 is flat and square as shown in fig. 2 and 3, and the housing 1 is provided with an air inlet 11 and an air outlet 12.

As shown in fig. 4 and 5, the air inlet 11 of the housing 1 is located on the upper surface and the lower surface of the housing 1, and the air outlet 12 is located on the circumferential surface of the housing 1. The air inlet of the air purification unit 2 faces the air inlet 11, and the air outlet of the air purification unit 2 may or may not face the air outlet 12 of the housing 1.

As shown in fig. 4 and 5, the casing 1 has two air inlets 11 on the upper surface and the lower surface, and two air outlets 12 are respectively disposed on two opposite peripheral surfaces of the casing 1. And the air outlet of the air cleaning unit 2 is arranged towards the air outlet 12 and the air inlet of the air cleaning unit 2 is arranged towards the air inlet 11. Therefore, two air purification units 2 are provided in the air purification apparatus. In particular, the upper surface and the lower surface of the housing 1 are respectively provided with openings to form the air inlet 11, the air inlet 11 exposes the air inlet of the air purification unit 2, and the air inlet of the air purification unit 2 is located at the position of the air inlet 11. The inner side of the air outlet 12 of the casing 1 is provided with a fan 5, so that the air flow in the casing 1 is guided to the air outlet 12 and discharged, and the air flow is guided to the air outlet 12 and discharged. Namely, the air purification unit 2 and the fan 5 are sequentially arranged in an air flow channel between the air inlet 11 and the air outlet 12 of the shell 1, and other functional modules can be arranged between the air purification unit 2 and the fan 5. The fan 5 is a vortex fan.

As shown in fig. 6, 7 and 8, the air inlets of the two air purification units 2 are respectively arranged downwards and upwards, and the air outlets thereof are two and are respectively arranged towards the air outlets on the two opposite peripheral walls of the housing 1. The external oil smoke gas enters the air purification unit 2 from the air inlet 11 of the housing 1, that is, the air inlet of the air purification unit 2, and is discharged from the air outlet of the air purification unit 2 after oil smoke separation is performed by the air purification unit 2, and the air outlet of the air purification unit 2 is perpendicular to the air inlet thereof, and then is discharged to the outside of the housing 1 from the air outlet 12 of the housing 1. On the wind channel between the air outlet of the air purification unit 2 and the fan 5 of the air outlet 12 of the shell 1, a sterilization module 3 and a refrigeration and heating module 4 can be arranged in sequence, and other functional modules such as a smell removal module and a dehumidification module can be arranged. Therefore, the soot gas passing through the air purifier can be purified and filtered into a clean gas, and further directly discharged from the outlet 12 of the casing 1.

As shown in fig. 9-14, for the structure of the two sets of air purification units 2, each set of air purification units 2 includes at least two cyclone tubes 21 extending in the same direction side by side, the cyclone tubes 21 are hollow and cylindrical, and the two ends of the cyclone tubes 21 are provided with openings to form air outlets 213, and the middle part of the side wall 211 of the cyclone tube 21 is provided with an opening extending along the axial direction of the cyclone tube 21 to form an air inlet 212. The periphery of the air inlet 212 is formed with a circle of wind scoops 214 extending outward, the wind scoops 214 include two opposite first guide surfaces 2141 and second guide surfaces 2142 extending in the axial direction of the cyclone tube 1, wherein the first guide surfaces 2141 extend perpendicularly from the air inlet 212 outward along the tangent line of the sidewall 211 of the cyclone tube 21, and the second guide surfaces 2142 extend from the air inlet 212 outward gradually away from the first guide surfaces 2141. Therefore, under the action of the fan, the oil smoke entering the cyclone tube 21 from the air inlet 212 can rotate and accelerate in the cyclone tube 21, and then the oil smoke gas collides with the sidewall of the cyclone tube 21, because there is friction between oil droplets and the sidewall of the cyclone tube 21, the oil droplet molecules will remain in the sidewall of the cyclone tube 21, and the gas separated from the oil droplet molecules gradually moves towards both ends, and is discharged from the air outlet 213.
