Detailed Description

Referring to fig. 1, the air cleaner includes a housing 1, a primary filter unit 2 and a secondary filter unit 3 disposed in the housing 1. An air inlet 4 and an air outlet 5 are arranged on the shell 1, an air passage 6 is arranged between the air inlet 4 and the air outlet 5, and the primary filtering unit 2 and the secondary filtering unit 3 are respectively arranged in the air passage 6. For example, the air inlet 4 is disposed at a side of the housing 1, and the air outlet 5 is disposed at a top of the housing 1. Of course, the positions of the intake vent 4 and the outtake vent 5 are not limited thereto. The air inlet 4 is communicated with the interior of the processing machine through a pipeline, air in the processing machine firstly enters the primary filtering unit 2 from the air inlet 4, most of oil mist in the air is retained in the primary filtering unit 2, and the primarily filtered air enters the secondary filtering unit 3 for further purification.

Referring to fig. 1, the primary filter unit 2 includes a capture device 7 and a primary fan 8. Specifically, referring to fig. 2 or 3, the catching device 7 includes a plurality of air inlet holes 9 and a catching member 10 disposed at an outlet side of the air inlet holes 9. The cross-sectional area of the air inlet openings 9 decreases in the direction of the air inlet, for example, the air inlet openings 9 may have a conical shape or a structure similar to a cone. Since the sectional area of the inlet openings 9 becomes gradually smaller, the wind is accelerated through the inlet openings 9. The trap member 10 has a porous structure with a large specific surface area, such as a ball, a brush, a net, etc. Wherein, the silk ball is a ball shape with multiple pores formed by rolling one or more line bodies; the brush comprises densely arranged bristles, and gaps are formed among the bristles; the net is formed by interlacing of wire bodies and has a pore structure. The primary fan 8 is used to create a pressure difference between the front side and the rear side of the trap 7, so that air enters the trap 7 from the air inlet holes 9 at a high velocity and impacts the trap member 10 having a large specific surface area, and most of the oil mist in the air is retained on the trap member 10.

In some embodiments, referring to fig. 1, the primary fan 8 is disposed at an outlet side of the capturing device 7, and the air entering the air duct 6 from the air inlet 4 is filtered by the capturing device 7 and then enters the primary fan 8.

In some embodiments, referring to fig. 2 or 3, the capturing device 7 includes a wind inlet plate 11 and a base plate 12 opposite to the wind inlet plate 11, the wind inlet plate 11 is provided with a nozzle 17, the nozzle 17 is provided with wind inlet holes 9, and the capturing member 10 is disposed on the base plate 12. Specifically, the air inlet plate 11 is provided with a plurality of holes, and the nozzles 17 are fixed in the holes. Further, referring to fig. 2, the catching member 10 is a steel wire ball, and is disposed corresponding to the air inlet hole 9. The substrate 12 may be a grid with steel wire balls bound to the grid with as large a gap as possible to reduce the resistance of air passing through the grid. Alternatively, referring to fig. 3, the catching members 10 may be metal bristles densely arranged on the base plate 12. When the air containing oil mist impacts the steel wire balls or the metal bristles, the oil mist in the air is stuck on the steel wire balls or the metal bristles, and the oil filtering effect is obvious.

In some embodiments, and with reference to fig. 4, the recovery member 10 is a metal mesh disposed opposite the air inlet plate 11, the air inlet plate 11 is provided with nozzles 17, and the nozzles 17 are provided with air inlet holes 9. Specifically, the air inlet plate 11 is provided with a plurality of holes, and the nozzles 17 are fixed in the holes. When the air containing oil mist hits the wire, the oil mist is also stuck to the wire.

In some embodiments, an oil receiving pan (not shown in the drawings) is arranged below the capturing device 7, and when more oil is deposited on the capturing part 10, oil drops can drop downwards, and the oil receiving pan can receive the dropped oil drops to prevent the oil drops from polluting the inside of the air purifier.

Referring to fig. 1, the secondary filter unit 3 includes a high efficiency filter element 13 and a secondary fan 14. The secondary filter unit 3 further filters the air of the primary filter unit 2. Because the primary filter unit 2 removes most of oil mist in the air, the oil content of the air entering the secondary filter unit 3 is low, and the service life of the secondary filter unit 3 is greatly prolonged.

In order to ensure the safety of the primary fan 8, the suction flow of the secondary fan 14 should be greater than that of the primary fan 8, so as to ensure that the interior of the air passage 6 is in a negative pressure state, and prevent oil mist from entering the fan circuit and damaging the fan.

The primary filter unit 2 serves the purpose of trapping most of the oil mist in the air by forcing the air to strike the porous trap member 10 at a high velocity, and therefore it is necessary to keep the suction amount of the primary fan 8 stable. If the amount of air provided by the machine does not meet the suction air volume requirement of the primary air blower 8, the air will impact the capture element 10 at a lower velocity, which impairs the oil removal capacity of the primary filter unit 2.

In the embodiment of the present disclosure, referring to fig. 5, a plurality of first adjusting ports 15 are disposed on the housing 1, and the first adjusting ports 15 communicate the air duct 6 between the primary filtering unit 2 and the air inlet 4 with the outside of the air purifier. The primary fan 8 with larger air suction volume is selected, the purification requirement of the processing machine with larger space size can be met, and the air can be supplemented through the first adjusting port 15 for the processing machine with smaller space size. When the amount of air in the processing machine is insufficient, the air outside the air cleaner can be supplemented to the primary filter unit 2 through the first adjusting port 15. The first adjusting openings 15 may be disposed around the air inlet 4, and the number of the first adjusting openings 15 may be plural, and the opening number of the first adjusting openings 15 is selected according to the air pressure level in the processing machine. When the amount of air in the processing machine is small, a larger number of first adjusting ports 15 can be opened to supplement more air to the primary filter unit 2. Of course, one or more first adjusting openings 15 with larger diameters may also be used, and a baffle (not shown in the figure) capable of opening and closing is arranged at the opening, and the size of the air inlet cross section area of the first adjusting opening 15 is adjusted by changing the opening and closing degree of the baffle. The first regulation port 15 may be disposed around the intake vent 4 of the air cleaner, but is not limited to this position.

In some embodiments, referring to fig. 6, the housing 1 is further provided with a plurality of second regulating ports 16, and the second regulating ports 16 communicate the air passage 6 between the primary filter unit 2 and the secondary filter unit 3 with the outside of the air purifier. The second regulating orifice 16 has at least the following functions: (1) compensating a part of the intake air from the outside to meet the larger air suction volume of the secondary fan 14; (2) when the high-efficiency filter element 13 is blocked, air can be discharged to the outside through the second adjusting opening 16, so that the air duct 6 can be prevented from forming a positive pressure area to damage the primary fan 8; (3) the service life of the filter element can be effectively evaluated through the second adjusting port 16, and when the second adjusting port 16 discharges air to the outside, the filter element is blocked, so that a user is reminded that the filter element needs to be replaced.

The air purifier adopts a double-stage filtering technology, the first-stage filtering unit 2 is additionally arranged, the first-stage filtering unit 2 filters most oil mist in the air by virtue of the capturing device 7 with low cost, the service life of the high-efficiency filter element 13 is greatly prolonged, the first-stage fan 8 and the second-stage fan 14 can select the fixed air volume fan with low cost, and the use cost of the air purifier is reduced.
