[0023] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] Please refer to Figures 1-6 , a filter screen structure of an extractor hood, comprising a first screen 1, a second screen 2 is clamped on the inner side of the first screen 1, a buckle pipe 11 is arranged on one side of the first screen 1, a first clamping groove 12 is arranged on the inner side of the buckle pipe 11, a plurality of 13 are arranged on the inner wall of the first screen 1, a limiting piece 21 is arranged on one side of the second screen 2, and a plurality of second clamping grooves 27 are arranged on the inner wall of the second screen 2.

[0025] Among them, the first screen 1 is clamped in combination with one side of the second screen 2 in a concave shape, the outer side of the second screen 2 is located on the same horizontal plane as the outer side of the first screen 1, the positions of 13 and the second clamping groove 27 are staggered with each other, the limiting piece 21 is clamped with the first clamping groove 12, and the clamping block 24 is located on the outer side of the first clamping groove 12 and abuts against the outer wall of the first screen 1.

[0026] Specifically, as shown in Figure 3 , the first screen 1 and the second screen 2 are clamped through the first clamping groove 12 and the limiting piece 21, and 13 and the second clamping groove 27 are staggered with each other, which can avoid the situations of oil hanging and oil leakage. Figure 3 Figure 2

[0027] According to Figure 7 , a sliding groove 22 is arranged on the inner wall of the limiting piece 21, a fixed rod 23 is fixedly arranged on the inner wall of the sliding groove 22, a clamping block 24 is slidably connected to the inner wall of the sliding groove 22, a limiting groove 25 is arranged on the inner wall of the clamping block 24, and a limiting rod 26 is slidably connected to the inner wall of the limiting groove 25.

[0028] Among them, the cross-sectional shape of the limiting rod 26 is T-shaped, the cross-sectional shape of the limiting groove 25 is adapted to the T-shaped, one side of the clamping block 24 is fixedly connected with the second clamping groove 27, and the other side of the second clamping groove 27 is fixedly connected with the fixed rod 23.

[0029] Specifically, by pushing the two clamping blocks 24 to move towards the inner wall of the limiting piece 21 and compressing the second clamping groove 27, until the clamping block 24 is completely located in the sliding groove 22, at this time, the limiting piece 21 is separated from the first clamping groove 12, and the separation of the first screen 1 and the second screen 2 can be realized.

[0030] ​​In summary, this range hood filter structure, through the arrangement of several 13s and second slots 27, works in conjunction with each other to improve the extraction of fumes without causing oil buildup or dripping. Furthermore, the staggered positions of the 13s and second slots 27 prevent the interior of the range hood from being seen through the first and second mesh screens 1 and 2, ensuring an aesthetically pleasing exterior. The engagement of the first slot 12 and the limiting member 21 facilitates the separation of the first and second mesh screens 1 and 2. Therefore, if the fume separation efficiency is slow during use, the limiting member 21 and the first slot 12 can be separated to achieve separation of the first and second mesh screens 1 and 2. Subsequently, the first and second mesh screens 1 and 2 can be cleaned separately, achieving convenient oil screen cleaning, improved grease separation in the fumes, and noise reduction.
