The main body has two air inlets (not shown in the figure) and two air outlets 2. The air inlet is located on the bottom surface of the main body 1, and the air inlet has a conventional structure, and there is no special structure, so it will not be described in detail here. The air outlet 2 is located on the top surface of the main body 1, and the air outlet 2 and the air inlet are both equipped with outer covers (the air outlet outer cover 3 is like figure 1 (Shown), the main body 1 is provided with an axial fan 4, the axial fan 4 is facing the air outlet 2, the axial fan 4 is installed on the fan mounting plate 5 of the main body 1, and the fan mounting plate 5 is located on the axial flow The outer circumference of the fan 4 is provided with a plurality of baffles 6, and the design of the baffles 6 can ensure that a plurality of wind flows are formed and flow out from the filter unit evenly. The air outlet channel formed by the adjacent baffle 6 is provided with a tuyere 7 which is connected with the second filter layer 9. The advantage of the axial flow fan 4 is that it has the advantages of 3-level speed adjustable, low power, self-carrying wind, low noise level, and strong suction, and it can completely suck oil fume into the filter unit. The axial fan 4 is only one of the options of the embodiment of the present invention, and other types of fans, such as centrifugal fans, can also be applied to the embodiments of the present invention.
[0040] The filter unit is arranged on the main body 1, and the filter unit includes at least two filter layers. The material of the filter layers can be the same or different. The purpose is to intercept and adsorb oil fume in stages, which can achieve rapid cooling of oil fume while improving the treatment effect of oil fume , And facilitate the maintenance of the filter layer. In an embodiment of the present invention, the filter unit includes a first filter layer 8, a second filter layer 9 and an air storage chamber 10 located between the first filter layer 8 and the second filter layer 9 arranged in the order from bottom to top, The structure of the first filter layer 8 includes a stainless steel filter screen, which is used to initially intercept macromolecular oil fume; the stainless steel filter screen is detachably connected to the main body 1, specifically: the stainless steel filter screen is equipped with "l" steel at both ends The steel sheet 11 is embedded in the “T”-shaped groove 12 on both sides of the main body 1. In order to prevent the relative sliding of the stainless steel filter screen after turning on the fan, a rotatable baffle 13 is provided at the outer end of the "T"-shaped groove 12. The baffle 13 is inserted on the screw 14 to realize the rotation function. It is fixed on the "T" groove 12, when the stainless steel filter screen is placed in the "T" groove 12, rotating the baffle 13 to block the opening of the "T" groove 12 can stabilize the stainless steel filter screen.
[0041] In an embodiment of the present invention, an oil storage tank 15 is provided below the stainless steel filter screen 8. The macromolecular oil fume intercepted by the stainless steel filter screen 8 forms oil droplets and is intercepted by the oil storage tank 15. The oil storage tank 15 can also be removed from the main body One way to remove it is: the oil storage tank 15 is provided with a convex edge 16 at both ends, and the convex edge 16 is provided with a groove 17 inward, and the main body 1 is located under the "T" groove 12 with a convex strip 18, The strip 18 matches the groove 17. When the oil storage tank 15 is pulled outward, the convex strip 18 slides relatively in the groove 17. The oil storage tank 15 and the convex strip 18 are made of plastic or stainless steel, which can prevent corrosion and Heat resistant. The inner side of the groove 17 and the surface of the convex strip 18 are roughened, and the mutual friction force between the contact surface of the convex strip 18 and the groove 17 is used to stabilize the oil storage tank 15.
[0042] In addition, the main body 1 is provided with a side cover 19, which is used to cover the stainless steel filter screen 8 and the oil storage tank 15. The side cover 19 can be designed as a structure that is completely detached from the main body 1, or a single side The disassembly structure, as long as the purpose of covering the stainless steel filter screen 8 and the oil storage tank 15 can be achieved. The design of the side cover belongs to a conventional structure and will not be described in detail here. When the stainless steel filter 8 and/or the oil storage tank 15 need to be cleaned, first open the side cover 19, and directly pull out the stainless steel filter 8 from the "T" groove 12, and/or directly pull out the oil storage tank 15 for cleaning OK.
[0043] The second filter layer 9 includes a kapok layer 20, a polylactic acid fiber layer 21, and an acrylic resin layer 22 in order from bottom to top. The kapok layer 20 has good water absorption and can further absorb oil smoke while removing moisture in the oil smoke. Then enter the polylactic acid fiber layer 21 and the acrylic resin layer 22 in sequence to further absorb oil fume and reduce the loss of these two treatment layers. The upper part of the second filter layer 9 communicates with the air outlet 2. The second filter layer 9 can also be detached from the main body 1, specifically: the main body 1 is provided with 4 spring clips (existing mechanism), the spring clips 23 and the main body 1 are fixed by bolts, when the side cover 19 is opened After removing the first layer of filter screen 8 and the oil storage tank 15, move the four spring clips 23, and the second layer of filter element 9 can be removed from the main body 1, and also taken out from the side cover 19.
[0044] In an embodiment of the present invention, two atomizing nozzles 24 are provided on the upper side of both sides of the air storage chamber 10, and the two atomizing nozzles 24 located on the same side of the main body 1 are connected to one by a micro pressure pump 25 The lotion storage bottle 26 and the two lotion storage bottles 26 are respectively arranged in the storage bottle slot 27 on the outer sides of the main body 1, and the micro pressure pump 25 is connected to the charging power module. In addition, in order to collect the oil droplets left from the inner wall of the air storage chamber 10, the bottom of the inner wall of the air storage chamber 10 is provided with an annular oil control groove 28. The inside of the annular oil control groove 28 has a "concave" structure, and the annular oil control groove 28 is provided with an oil outlet. The pipeline communicates with the oil storage tank 15 (not shown in the figure). There are two oil outlet pipelines 36 in total, which extend from the rear of the main body 1 to the top of the oil storage tank to ensure that oil droplets can fall into the oil storage tank 15.

Example Embodiment

[0049] Example 2
[0050] A specific embodiment of the present invention provides a method for filtering oil fume produced by barbecue, which uses the filter of embodiment 1, and includes the following steps:
[0051] Prepare oil fume lotion and put it into lotion storage bottle;
[0052] Turn on the fan and introduce the oil fume from the air inlet into the filter unit. After the first filter layer is filtered, the large particles in the oil fume are intercepted;
[0053] At the same time, the micro pressure pump is turned on, and the remaining oil fume entering the air storage chamber is wrapped in it under the action of the atomized lotion. A small part of it will hang on the inner wall of the air storage chamber, and most of the droplets will be affected by the fan. Continue to enter the second filter layer for processing; the processed gas is discharged from the air outlet. The test results of oil fume concentration before and after treatment are shown in Table 1.

Example Embodiment

[0054] Example 3
[0055] The specific embodiment of the present invention provides a method for filtering oil fume generated by barbecue. The operating method and environment for generating oil fume are approximately the same as that of embodiment 2. The difference between the filter used and embodiment 1 is that no atomizing nozzle is designed in the air storage room , There is no lotion storage bottle and other related devices, and the second filter layer has only one layer structure of acrylic resin layer. The treatment method is the same as in Example 2 except for the atomization process. The test results of oil fume concentration before and after treatment are shown in Table 1.
