[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] See also Figure 1 The embodiment of the present application provides an air curtain range hood, comprising a frame 10, an air guide plate 20 and a filter module 30. The frame 10 is provided with an air outlet 11, a smoke extraction port 12 and an air inlet 13. The air outlet 11 is communicated with the air inlet 13. The air guide plate 20 is connected to the frame 10 and is located between the air outlet 11 and the smoke extraction port 12, and is used to separate a natural wind area and an oil fume area. The filter module 30 is movably connected to the frame 10 and is located between the air inlet 13 and the air outlet 11, and is used to filter the natural wind flowing from the air inlet 13 to the air outlet 11.

[0034] In this embodiment, the smoke extraction port 12 can be one or more. When there are multiple smoke extraction ports 12, the multiple smoke extraction ports 12 are arranged at intervals along the width direction of the frame 10, and the multiple smoke extraction ports 12 are all located on the same side of the air guide plate 20. Therefore, whether there are multiple smoke extraction ports 12 or one smoke extraction port 12, only one air guide plate 20 is needed to separate it from the air outlet 11. In this way, multiple smoke extraction ports 12 can be set without adding air guide plates 20, thereby improving the speed of extracting oil smoke; the air outlet 11 can be one or more. When there are multiple air outlets 11, the air guide plates 20 are located at the same side of the frame 10. The filter module 30 is disposed between the smoke outlet 12 and one of the multiple air outlets 11 to separate the natural wind area and the oil fume area, so that the natural wind area and the oil fume area can be arranged separately; the air inlet 13 can be connected to the multiple air outlets 11. Specifically, the multiple air outlets 11 can be connected to the air inlet 13 through the same air duct. The filter module 30 is disposed in the air duct, so that the natural wind blown in from the air inlet 13 is filtered by the filter module 30 and blown out from the multiple air outlets 11, thereby reducing the impurities contained in the natural wind, and at the same time increasing the air volume of the natural wind blown in, thereby improving the comfort of using the range hood. When there is only one air outlet 11, the air guide plate 20 is disposed between the air outlet 11 and the smoke outlet 12 to separate the natural wind area and the oil fume area; the filter module 30 is disposed between the air outlet 11 and the air inlet 13 to filter the natural wind flowing from the air inlet 13 to the air outlet 11. The filter module 30 can move relative to the frame 10 in the front-rear direction, so that the filter module 30 can be installed on or removed from the frame 10 , thereby facilitating the replacement of the filter module 30 .

[0035] In actual application, the wind curtain range hood also includes a fan 40 and a smoke extractor 50, both of which are installed on the frame 10, the input end of the fan 40 is connected to the air inlet 13, and is used to suck external natural wind into the air inlet 13, the output end of the fan 40 is connected to the filter module 30, and the natural wind entering from the air inlet 13 is guided to the filter module 30, and after being filtered by the filter module 30, it is finally blown out from the air outlet 11; the input end of the smoke extractor 50 is connected to the smoke outlet 12, and is used to absorb oil smoke.

[0036] Compared with the prior art, the present application provides an air curtain smoke machine, including a frame 10, an air guide plate 20 and a filter module 30. The frame 10 is provided with an air outlet 11, a smoke outlet 12 and an air inlet 13. The air outlet 11 is connected to the air inlet 13. The air guide plate 20 is connected to the frame 10 and is located between the air outlet 11 and the smoke outlet 12. The filter module 30 is movably connected to the frame 10 and is located between the air inlet 13 and the air outlet 11. The present application sets the air guide plate 20 to connect the air outlet 11 and the smoke outlet 12. 12 is separated, and the air outlet 11 and the smoke outlet 12 are arranged relatively separately, so that the air outlet 11 and the smoke outlet 12 are avoided from being connected, and the natural wind output by the air outlet 11 is prevented from mixing with the oil smoke sucked by the smoke outlet 12, so that the natural wind is separated from the oil smoke, and the smoke collecting effect of the range hood is improved; by setting the filtering module 30, the natural wind flowing from the air inlet 13 to the air outlet 11 is filtered, so that the natural wind discharged through the air outlet 11 is free of impurities, thereby improving the use effect of the range hood.

[0037] See also Figure 2 and Figure 3 There are multiple air outlets 11, including a first air outlet 111, a second air outlet 112 and a third air outlet 113. The second air outlet 112 and the third air outlet 113 are located on both sides of the first air outlet 111, respectively. The second air outlet 112, the third air outlet 113 and the first air outlet 111 are arranged along the outer contour of the smoke extraction port 12. In this embodiment, the multiple air outlets 11 are arranged along the outer contour of the smoke extraction port 12, and a wind curtain area is formed between the multiple air outlets 11. The smoke extraction port 12 is in the wind curtain area. When the natural wind is output from top to bottom through the multiple air outlets 11, the wind curtain area limits the oil smoke within its range, so that the smoke extraction port 12 can absorb the oil smoke in the wind curtain area, and the oil smoke is limited in the wind curtain area, so as to prevent the smoke extraction port 12 from incompletely sucking the oil smoke, and further improve the smoke collection effect of the range hood.

[0038] Among them, the second air outlet 112 and the third air outlet 113 are arranged relatively along the left and right directions of the frame 10, and the distance between the second air outlet 112 and the third air outlet 113 is greater than the distance of the smoke outlet 12; the first air outlet 111 is located in front of the second air outlet 112 or the third air outlet 113, and at the same time, the first air outlet 111 is located in front of the smoke outlet 12, and the second air outlet 112 and the third air outlet 113 are respectively located on the left and right sides of the smoke outlet 12, so that the natural wind output between the first air outlet 111, the second air outlet 112 and the third air outlet 113 can block the oil smoke, so as to facilitate the smoke outlet 12 to keep the oil smoke within the suction range during the suction process to prevent oil smoke leakage.

[0039] See also Figure 4The above-mentioned air guide plate 20 includes a connecting portion 21 and an air guide portion 22. The connecting portion 21 is connected to the frame 10, and the air guide portion 22 is connected to the connecting portion 21, and serves as a partition between the natural wind area and the oil fume area. The air guide portion 22 is arranged on the side of the connecting portion 21 facing away from the frame 10, and the air guide portion 22 is connected to the connecting portion 21, so that the air guide portion 22 is fixed between the air outlet 11 and the smoke outlet 12. The air guide portion 22 serves as a partition between the natural wind area and the oil fume area, so that the natural wind is separated from the oil fume, and the connection between the air outlet 11 and the smoke outlet 12 is avoided, and the natural wind output from the air outlet 11 is prevented from mixing with the oil fume sucked by the smoke outlet 12, thereby improving the smoke collection effect of the range hood. Optionally, the connecting portion 21 and the air guide portion 22 are an integrally formed structure, which improves the connectivity between the connecting portion 21 and the air guide portion 22 and ensures the stability of the air guide plate 20.

[0040] See also Figure 5 The above-mentioned connecting portion 21 is in the air outlet 11, and the connecting portion 21 is connected to the inner side wall of the air outlet 11 formed in the frame 10. In the present embodiment, the present application is provided with a plurality of air outlets 11, wherein the first air outlet 111 is arranged adjacent to the smoke outlet 12, so the connecting portion 21 is in the first air outlet 111, and the outer contour of the connecting portion 21 contacts the inner contour of the air outlet 11, so that the connecting portion 21 is fixed to the air outlet 11, thereby facilitating the air guide plate 20 to be fixed between the first air outlet 111 and the smoke outlet 12, so that the natural wind is separated from the oil smoke; the outer contour of the connecting portion 21 is adapted to the inner contour of the air outlet 11, and optionally, the air outlet 11 is conical, and the air outlet 11 gradually widens from the inside to the outside, on the contrary, the connecting portion 21 gradually widens from the outside to the inside.

[0041] See also Figure 6 The air guide portion 22 is arranged obliquely relative to the surface of the frame 10, and guides the natural wind output through the first air outlet 111 or the oil smoke sucked through the smoke extraction port 12. At this time, the air guide portion 22 is arranged obliquely relative to the front surface of the frame 10, and tilted downward. The air guide portion 22 guides the natural wind output through the first air outlet 111 or the oil smoke sucked through the smoke extraction port 12. The natural wind output from the first air outlet 111 is tilted as the upper surface of the air guide portion 22 is tilted, so that the natural wind output from the first air outlet 111 is tilted toward the user's chest along the tilted direction, avoiding the natural wind output from the first air outlet 111 from being directed toward the user's head, thereby improving the user experience. In addition, the oil smoke sucked by the smoke extraction port 12 is tilted as the lower surface of the air guide portion 22 is tilted, so that the oil smoke sucked by the smoke extraction port 12 is tilted toward the range hood along the tilted direction.

[0042] Among them, the connecting part 21 is swingably connected to the frame 10, and the angle of the air guide part 22 is adjusted as the connecting part 21 swings relative to the frame 10, thereby modulating the inclination angle of the air guide part 22 relative to the surface of the frame 10, and then adjusting the flow direction of the natural wind output through the air outlet 11. At the same time, by setting the swing angle of the connecting part 21, it can drive the air guide part 22 to swing to cover the first air outlet 111 or the smoking port 12, so that according to the user's use needs, the air guide part 22 can selectively cover the first air outlet 111 and the smoking port 12 to control the opening and closing of the first air outlet 111 and the smoking port 12.

[0043] See also Figure 7 The filter module 30 includes a housing 31 and at least one filter element 32. The housing 31 is movably connected to the frame 10. The filter element 32 is connected to the housing 31. The filter element 32 is used to filter the natural wind flowing from the air inlet 13 to the air outlet 11. The housing 31 is a main body and carries at least one filter element 32. There may be multiple filters 32. The multiple filters 32 are all installed on the housing 31. The multiple filters 32 are stacked up and down along the height direction of the housing 31. The filter effect of the filter element 32 relative to the natural wind is increased by arranging multiple filters 32, thereby improving the filter effect of the filter module 30. The filtering precision of the multiple filters 32 stacked up and down along the height direction of the housing 31 is different, so as to realize the multi-stage filtering function of the filter module 30. The housing 31 is movably connected to the frame 10. Specifically, the housing 31 can be moved along the front and rear direction of the frame 10, so that the housing 31 is exposed from the inside of the frame 10, so that the filter element 32 can be replaced in time to prevent affecting the filtering effect.

[0044] The frame 10 is provided with a slot 14, which connects the air outlet 11 and the air inlet 13. The filter element 32 is accommodated in the shell 31. The shell 31 is movably connected to the slot 14 and moves in the horizontal direction. The slot of the slot 14 faces the front of the frame 10. The shell 31 is movably connected to the slot 14 along the front and rear directions of the frame 10. At this time, the shell 31 can be selectively pulled out of the slot 14 or stored in the slot 14 under the action of external force, so that the installation and replacement of the shell 31 are relatively simple. The slot 14 connects the first air outlet 111 and the air inlet 13, so that natural wind is filtered from the air inlet 13 and then blown to the first air outlet 111 by the filter element 32.

[0045] See also Figure 7 , Figure 8 and Fig. 9The filter module 30 also includes a snap member 33 and a plurality of clamping arms 34. The snap member 33 is arranged on the shell 31. The plurality of clamping arms 34 are swingably connected to the frame 10 and clamp or release the snap member 33. At this time, the plurality of clamping arms 34 are arranged on one side of the frame 10. The plurality of clamping arms 34 are swingably connected to the frame 10, so as to adjust the plurality of clamping arms 34 to approach or move away from each other, so as to make the plurality of clamping arms 34 clamp or release the snap member 33. When the plurality of clamping arms 34 clamp the snap member 33, the shell 31 is fixed to the frame 10 by clamping the snap member 33 by the plurality of clamping arms 34, so as to facilitate the natural wind to be filtered through the filter element 32 connected to the shell 31, and prevent the shell 31 from being separated from the frame 10; when the plurality of clamping arms 34 release the snap member 33, the shell 31 moves relative to the frame 10 under the action of external force, so as to expose it from the frame 10.

[0046] The plurality of clamping arms 34 are arranged relative to each other and enclose an arc-shaped slot, and the snap member 33 is engaged in the arc-shaped slot, and the outer contour of the snap member 33 is adapted to the inner contour of the arc-shaped slot, so that the clamping arms 34 clamp the snap member 33 more firmly. When the plurality of clamping arms 34 clamp the snap member 33, the plurality of clamping arms 34 approach each other and clamp the snap member 33 in the arc-shaped slot to fix the shell 31 to the frame 10. When the plurality of clamping arms 34 release the snap member 33, the plurality of clamping arms 34 move away from each other, so that the shell 31 can be exposed from the frame 10 under the pull of external force.

[0047] See also Fig. 9 and Fig.10 The filter module 30 also includes a moving member 35 and a positioning member 36. The frame 10 is provided with a moving groove 15 and a track groove 16. The moving member 35 is arranged on one side of the clamping arm 34. The moving member 35 is movably connected to the moving groove 15 and is triggered by the latch 33; one end of the positioning member 36 is connected to the moving member 35, and the other end is inserted into the track groove 16; the moving member 35 is arranged on the rear side of the clamping arm 34, and the moving member 35 is movably connected to the moving groove 15, so as to adjust the position of the moving member 35 relative to the frame 10, and the moving member 35 is triggered by the latch 33. When the latch 33 contacts the moving member 35 for the first time, multiple clamping arms 34 clamp the latch 33, so that the housing 31 is fixed to the frame 10. When the latch 33 contacts the moving member 35 for the second time, multiple clamping arms 34 release the latch 33, so that the housing 31 moves relative to the frame 10 under the action of external force.

[0048] Specifically, the moving member 35 is elastically connected to the moving groove 15 so that the moving member 35 can move elastically relative to the frame 10. One end of the positioning member 36 is connected to the moving member 35, and the other end is inserted into the track groove 16. The positioning member 36 is inserted into the track groove 16 as the moving member 35 moves, so that the track groove 16 limits the movement of the positioning member 36. Optionally, the track groove 16 is V-shaped.

[0049] Among them, the track groove 16 is a V-shaped line with continuous line segments, and the track groove 16 has a first position and a second position. When the other end of the positioning member 36 is in the first position of the track groove 16, the other end of the positioning member 36 is limited by the inner side wall of the track groove 16 to facilitate the engagement of the moving member 35 relative to the frame 10; when the other end of the positioning member 36 is in the second position of the track groove 16, the other end of the positioning member 36 moves along the inner side wall of the track groove 16 to facilitate the movement of the moving member 35 relative to the frame 10.

[0050] In order to realize the elastic movement of the moving member 35 and the frame 10, a spring 37 is provided between the moving member 35 and the frame 10, one end of the spring 37 is connected to the frame 10, and the other end of the spring 37 is connected to the moving member 35, thereby realizing the elastic movement of the moving member 35 relative to the frame 10. Optionally, the spring 37 applies an elastic force to the moving member 35, so that the moving member 35 moves relative to the frame 10 under the action of the elastic force.

[0051] See again Figure 7 The shell 31 is provided with a receiving groove 311, and the filter element 32 is detachably connected to the receiving groove 311 and can be detached from or accommodated in the receiving groove 311. At this time, the receiving groove 311 is recessed inwardly from the shell 31, and the notch of the receiving groove 311 faces the right. The filter element 32 is detachably connected to the receiving groove 311 and can be detached from or accommodated in the receiving groove 311, so that the filter element 32 can be replaced after long-term use. When the filter element 32 is accommodated in the receiving groove 311, the filter element 32 is fixed to the shell 31, so that the filter element 32 can filter the natural wind flowing from the air inlet 13 to the air outlet 11. When the filter element 32 is detached from the receiving groove 311, the filter element 32 can be replaced. Among them, the moving direction of the filter element 32 relative to the shell 31 and the moving direction of the shell 31 relative to the frame 10 have an angle, and the angle is 0 to 180 degrees; optionally, the moving direction of the filter element 32 relative to the shell 31 is the left-right direction, and the moving direction of the shell 31 relative to the frame 10 is the front-back direction, so as to facilitate operations in different directions, thereby improving the convenience of movement of the shell 31 relative to the frame 10, and the convenience of movement of the filter element relative to the shell 31.

[0052] Different from the prior art, the embodiment of the present application provides an air curtain range hood, including a frame 10, an air guide plate 20 and a filter module 30. The frame 10 is provided with an air outlet 11, a smoke extraction port 12 and an air inlet 13. The air outlet 11 is connected to the air inlet 13. The air guide plate 20 is connected to the frame 10 and is located between the air outlet 11 and the smoke extraction port 12, and is used to separate the natural wind area and the oil fume area. The filter module 30 is movably connected to the frame 10 and is located between the air inlet 13 and the air outlet 11, and is used to filter the natural wind flowing from the air inlet 13 to the air outlet 11. Compared with the prior art, the present application separates the air outlet 11 and the smoke outlet 12 by setting an air guide plate 20. The air outlet 11 and the smoke outlet 12 are arranged relatively separately, thereby avoiding the air outlet 11 and the smoke outlet 12 from being connected, and preventing the natural wind output by the air outlet 11 from mixing with the oil smoke sucked by the smoke outlet 12, so as to separate the natural wind from the oil smoke, thereby improving the smoke collection effect of the range hood; by setting a filter module 30, the natural wind flowing from the air inlet 13 to the air outlet 11 is filtered, so that the natural wind discharged through the air outlet 11 is free of impurities, thereby improving the use effect of the range hood.

[0053] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
