Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 and 2 show a perspective view and an internal structure view of an air cleaning apparatus according to some embodiments of the present invention, respectively. Referring to fig. 1 and 2, the air cleaning apparatus includes:

the air conditioner comprises a box body 1, an air inlet 2 and an air outlet 3; and

the primary filtering unit 4, the secondary filtering unit 5 and the fan 6 are sequentially arranged between the air inlet 2 and the air outlet 3;

wherein, the primary filter unit 4 comprises a nozzle unit 7 with the flow area gradually reduced along the airflow direction and a porous component 8 which is arranged at the outlet side of the nozzle unit 7 and is formed by metal wires, and the porous component 8 is used for capturing the oil mist in the air when the air passes through.

Fig. 3 is a perspective view of a nozzle unit in an embodiment of the present invention. In some embodiments, referring to fig. 3, the nozzle unit 7 includes a plurality of conical nozzles 9 and a support plate 10 supporting the conical nozzles 9, and the flow area of the conical nozzles 9 is gradually reduced in the air flow direction.

After the fan 6 is started, air in the environment is sucked into the box body 1 from the air inlet 2, and the air is discharged from the air outlet 3 after being filtered by the primary filtering unit 4 and the secondary filtering unit 5 in sequence. The primary filter unit 4 is used for removing larger solid particles and most of the oil mist in the air, and the secondary filter unit 5 is used for filtering small particles and remaining small oil mist particles in the air.

The primary filter unit 4 is responsible for the primary filtration of the oil mist. The primary filtering unit 4 is divided into two steps when filtering oil mist, wherein the first step is to accelerate air containing oil mist, and the first step is realized by a nozzle unit 7 with the flow area gradually reduced along the airflow direction; the second step is to capture the oil mist in the air, which is achieved by the porous member 8 formed by the wire. The porous member 8 has pores which allow air to pass therethrough and has a large specific surface area. The air impacts the porous member 8 at a relatively high velocity, causing the oil mist particles to strike the porous member 8 and become stuck to the wire. Further, after an oil layer is formed on the wire, the viscosity of the surface of the wire is increased, so that oil mist particles in the air can be further captured when the oil mist particles continue to collide. In addition, due to the viscosity of the oil layer, a part of the larger and smaller solid particles may also adhere to the porous member 8. The porous member 8 is formed by using a metal wire, which has the advantage of low cost, and prolongs the service life of the high-cost secondary filter unit 5.

In some embodiments, the inlet side of the nozzle unit 7 is also provided with a porous member 8. The air is degreased once before it enters the nozzle unit 7.

In some embodiments, the primary filter unit 4 further comprises a primary filter element 11, the nozzle unit and the porous member being disposed between the primary filter element and the air inlet; the secondary filtration unit 5 comprises a high efficiency filter cartridge. The primary filter element 11 and the high-efficiency filter element further filter the air. Since the primary filter unit 4 has removed most of the oil mist from the air, the oil removal pressure of the primary filter element 11 and the high-efficiency filter element is greatly reduced.

Fig. 4 to 6 show schematic views of porous members in different embodiments, respectively. In some embodiments, the porous member 8 is formed from a side-by-side arrangement of wires; alternatively, the porous member 8 is woven from intersecting wires; alternatively, the porous member 8 comprises a wire ball formed by a wire cluster. The porous member 8 is supported on an outer frame which also defines a passage for the gas flow together with the outer frame of the nozzle unit 7 and the outer frame of the primary filter cartridge 11. As shown in FIG. 3, the porous members 8 are arranged in parallel by a transverse wire or longitudinally or obliquely, and air can pass between the adjacent wires. The metal wire may have a plurality of layers in the moving direction of the gas flow. As shown in fig. 4, the porous member 8 may be a metal mesh woven from crossed wires, through which air may pass, the mesh size being selected as desired. The metal mesh may have multiple layers. As shown in fig. 5, the porous member 8 may be a wire ball formed by aggregating wires, and the wires in the wire ball are relatively disordered and the formed pores are more irregular than those in the former two, so as to achieve better oil removing effect. Optionally, one wire ball is provided for each nozzle.

In some embodiments, referring to fig. 2, the inside of the box 1 sequentially includes, from bottom to top, a first area 13 provided with the first-stage filtering unit 4, a second area 14 provided with the second-stage filtering unit 5, and a third area 15 provided with the fan 6, a side wall of the first area 13 is provided with an air inlet 2, a side wall or a top wall of the third area 15 is provided with an air outlet 3, the nozzle unit 7 is opposite to the air inlet 2, and the air flow passes through the first-stage filtering unit 4 in the transverse direction and then passes through the second-stage filtering unit 5 in the vertical direction. The primary filter unit 4 does not completely fill the first zone 13 but forms a buffer zone in front of the outlet of the primary filter unit 4. The air flow enters the buffer zone after passing through the primary filter unit 4 transversely and then passes through the secondary filter unit 5 upwards. Purifier side air inlet, top are aired exhaust, and inside adopts middle and upper layout mode down, and such overall arrangement has the advantage that area is little.

In some embodiments, referring to fig. 2, the air conditioner further includes a manual quick clamp 17, the air inlet 2 is formed in a side wall of the box body 1, the manual quick clamp 17 abuts the primary filter unit 4 against an inner side of the side wall of the box body 1, and the nozzle unit 7 is opposite to the air inlet 2. The primary filter unit 4 adopts a fastening mode of the manual quick clamp 17, is quick to disassemble and assemble, and is convenient to replace the primary filter element 11 and disassemble the primary filter unit for cleaning.

In some embodiments, referring to fig. 2, a first supporting frame 18 for supporting the primary filtering unit 4 is disposed at a lower end of the first region 13, a second supporting frame 19 for supporting the secondary filtering unit 5 is disposed between the first region 13 and the second region 14, and manual quick clamps 17 for tightly supporting the primary filtering unit 4 on a side wall of the box 1 are respectively disposed on the first supporting frame 18 and at a bottom of the second supporting frame 19.

In some embodiments, referring to fig. 2, the four corners of the second supporting frame 19 are respectively provided with handle bolts 20 extending upward and supporting the frame of the secondary filtering unit 5, and a limiting portion 21 is provided above the secondary filtering unit 5 for limiting the frame of the secondary filtering unit 5 from above. The secondary filtering unit 5 also adopts a quick-release structure, so that the secondary filtering unit 5 is convenient to replace. In some embodiments, a manual quick clamp may be used in place of the handle bolt 20.

In some embodiments, referring to fig. 7, the front surfaces of the first section 13 and the second section 14 have a detachable panel 22. The panel 22 covers the front faces of the first and second sections 13 and 14, and when the panel 22 is removed, the primary and secondary filter units 4 and 5 can be directly replaced.
