In this embodiment, the number of the buffer blocks 113 is two, for example, and the two buffer blocks 113 are respectively disposed on two sides of the bottom end of the first plate 11.

Referring to fig. 1 to 3, in an embodiment, a first oil screen 114 is disposed at the first air inlet 111, and a plurality of first filtering holes 1141 are disposed on the first oil screen 114. Specifically, the first oil screen 114 is a concave surface recessed toward the inside of the smoke collection chamber 101. Thus, on the one hand, the first oil screen 114 performs a filtering function on oil smoke and a guiding function on oil stains; on the other hand, when the surface of the first oil screen 114 is a concave surface, the first oil screen has a good smoke collecting effect, and is beneficial to sucking external oil smoke into the smoke collecting cavity 101. Specifically, the shape of the first filter holes 1141 may be, for example, a strip-shaped hole, a square-shaped hole, a circular hole, an elliptical hole, etc., and is not limited herein and may be set according to actual conditions. In addition, the first oil screen 114 is detachably and fixedly disposed on a mouth wall of the first air inlet 111. When the first oil screen 114 needs to be cleaned and maintained, the first oil screen 114 is detached from the first air inlet 111, so that the first oil screen 114 can be cleaned or maintained. In addition, when the first oil screen 114 is fixedly arranged on the opening wall of the first air inlet 111, the stability is better, and a better smoke gathering effect and a filtering effect are achieved.

Referring to fig. 1 to 3, in an embodiment, a second oil net 13 and a second plate 14 are further disposed on the front surface of the body 10, and the first plate 11, the second oil net 13 and the second plate 14 are sequentially connected from top to bottom. The fuselage 10 also includes a bottom panel 15, and the second panel 14 is connected to the bottom panel 15. The second oil screen 13 is provided with a plurality of second filter holes 131, and the smoke collection chamber 101 is communicated with the external environment of the body 10 through the second filter holes 131. Therefore, no matter the door panel 20 closes or opens the first air inlet 111, the smoke collection chamber 101 is communicated with the external environment of the body 10 through the second filtering hole 131, so that when the opening and closing type range hood works, at least a part of oil smoke enters the smoke collection chamber 101 after being filtered through the second oil mesh 13 and is discharged into the common flue.

Similar to the first filter holes 1141, the second filter holes 131 may be, for example, elongated holes, square holes, circular holes, elliptical holes, etc., which are not limited herein and may be arranged according to actual situations.

Referring to fig. 1 to 3, in one embodiment, the second oil screen 13 and the second plate 14 are concave surfaces that are concave toward the interior of the smoke collection chamber 101. Therefore, the formed concave surface has a gathering effect on the oil smoke, and the oil smoke is favorably sucked into the smoke collection cavity 101 through the second oil net 13.

Referring to fig. 1 to 3, further, the body 10 further includes two side panels 16 disposed opposite to each other. Two sides of the bottom panel 15, two sides of the first plate 11, two sides of the second oil screen 13 and two sides of the second plate 14 are respectively and correspondingly connected with the two side panels 16.

Referring to fig. 1, 3 and 5, a smoke barrier 17 is further disposed on the front surface of the body 10 between the first plate 11 and the second oil screen 13. The first plate 11 is connected to the second oil screen 13 through a smoke barrier 17. The smoke barrier 17 and the second oil screen 13 are inclined at the same angle with respect to the back surface plate 18. The inclination angle of the first plate 11 with respect to the back plate 18 is a1, the inclination angle of the smoke barrier 17 with respect to the back plate 18 is a2, and the inclination angle of the second oil net 13 with respect to the back plate 18 is a 3. Wherein a1 is less than a2, a1 is, for example, from 10 ° to 30 °, a2 is, for example, from 30 ° to 75 °, and a is, for example, from-10 ° to 10 °. Thus, the first plate 11, the smoke barrier 17, the second oil screen 13, and the second plate 14 form a structure similar to a step. In the working process of the opening-closing type range hood, when the door panel 20 opens the first air inlet 111, a part of oil smoke enters the smoke collection cavity 101 through the second oil screen 13, and the other part of oil smoke flows upwards along the smoke baffle 17 and enters the smoke collection cavity 101 through the first oil screen 114, so that the smoke exhaust effect of the opening-closing type range hood can be further improved.
