[0027] As shown in Figures 1 to 7 The present embodiment provides a range hood, which comprises a hood main body 1, the hood main body 1 has an air inlet 11, further comprises a first oil screen 2, a second oil screen 3, a driving device 4 and a panel assembly 5, wherein the first oil screen 2 and the second oil screen 3 are arranged at the position of the air inlet 11, one end of the first oil screen 2 is hinged to the hood main body 1, the other end is hingedly connected to one end of the second oil screen 3, the other end of the second oil screen 3 is hinged to the middle part of the panel assembly 5, the upper end of the panel assembly 5 is slidingly connected to the hood main body 1, the output end of the driving device 4 is connected to the first oil screen 2 to drive the first oil screen 2 to make a turnover movement, the first oil screen 2 drives the second oil screen 3 to make a turnover movement, and finally drives the panel assembly 5 to expand outward, and the first oil screen 2, the second oil screen 3 and the panel assembly 5 jointly expand or reduce the air inlet 11.

[0028] In the present embodiment, the first oil screen 2 and the second oil screen 3 are rotated to drive the panel assembly 5 to move back and forth along the horizontal direction of the hood main body 1, the first oil screen 2, the second oil screen 3 and the panel assembly 5 jointly expand or reduce the air inlet 11, so that the range hood realizes the straight suction and exhaust function of the top suction hood shape, and realizes the low air inlet 11 suction and exhaust function of the side suction hood shape, the range hood combining the suction and exhaust functions of the above two shapes, further moves the air inlet 11 of the range hood downward and further expands the area of the air inlet, so that the range hood realizes a lower air inlet negative pressure area and a larger air inlet negative pressure area, in addition, when the range hood reduces the air inlet 11 to enter the shutdown state after cooking, it also realizes a smaller kitchen space occupation area of the range hood, so that the kitchen is more beautiful and clean, the structure is simple, the air inlet 11 of the range hood can be further moved downward, and the smoke suction area of the air inlet 11 is further expanded.

[0029] Further, the panel assembly 5 comprises a movable panel 51, a fixed shell 52 and a sliding mechanism 53, wherein the movable panel 51 is movably arranged on the smoke machine body 1 through the sliding mechanism 53 arranged on the smoke machine body 1 and can be moved and unfolded in the horizontal direction, the fixed shell 52 is arranged on the back of the movable panel 51 and located at the position above the smoke inlet 11, the active end of the sliding mechanism 53 is connected with the fixed shell 52, the middle part of the movable panel 51 is connected with the second oil screen 3, the structure is simple and reasonable, and under the rotating action of the first oil screen 2 and the second oil screen 3, the movable panel 51 moves forward and backward along the horizontal direction of the smoke machine body 1 through the sliding mechanism 53.

[0030] Preferably, the sliding mechanism 53 comprises a first guide rail 531 and a second guide rail 532, wherein the first guide rail 531 and the second guide rail 532 are arranged on the two sides of the smoke machine body 1 respectively, and the two sides of the fixed shell 52 are connected with the first guide rail 531 and the second guide rail 532 respectively, which is reasonable in design and can make the smoke machine body 1 and the movable panel 51 slide together, and also limits the expansion and contraction movement of the movable panel 51.

[0031] Specifically, the fixed shell 52 has a first surrounding plate 521, a second surrounding plate 522 and a third surrounding plate 523 connected in sequence, wherein the first surrounding plate 521 is arranged at the left side of the movable panel 51, the second surrounding plate 522 is arranged at the upper end of the movable panel 51, and the third surrounding plate 523 is arranged at the right side of the movable panel 51, and through the combined action of the first surrounding plate 521, the second surrounding plate 522 and the third surrounding plate 523, the external oil fume is prevented from entering the smoke machine body 1 directly through the movable panel 51, which is simple in structure and can effectively prevent the external oil fume from entering the smoke machine body 1 directly through the movable panel 51.

[0032] In the embodiment, the front panel is arranged at the lower position of the movable panel 51, so as to form the air inlet 11 of the range hood between the front panel and the movable panel 51. When the air inlet 11 of the range hood is reduced, the range hood can continue to guide the external oil fume into the range hood main body 1. Thus, the range hood uses the low gear to cope with the scene of less oil fume during cooking, that is, the range hood can continue to extract the oil fume according to the current state of the air inlet 11 at the wind speed of the low gear. If it is needed to increase the suction capacity of the range hood, the actions of the first oil screen 2, the second oil screen 3 and the movable panel 51 can be controlled to expand the air inlet 11. Thus, the range hood uses the high gear to cope with the scene of more oil fume during cooking, that is, the range hood can continue to extract the oil fume according to the state of the expanded air inlet 11 at the wind speed of the high gear. Thus, the negative pressure area of the air inlet 11 of the range hood is further lowered, and the smoke suction area of the air inlet 11 is further expanded, thereby greatly improving the suction capacity of the range hood. In the embodiment, the first guide rail 531 includes a first inner guide rail and a first outer guide rail. The first inner guide rail is mounted on the inner wall of the range hood main body 1, and the first outer guide rail is mounted on the outer wall of the first surrounding plate 521. The first inner guide rail and the first outer guide rail are cooperatively actuated to slidably connect the first surrounding plate 521 and the range hood main body 1 together. Similarly, the second guide rail 532 includes a second inner guide rail and a second outer guide rail. The second inner guide rail is mounted on the inner wall of the range hood main body 1, and the second outer guide rail is mounted on the outer wall of the third surrounding plate 523. The second inner guide rail and the second outer guide rail are cooperatively actuated to slidably connect the third surrounding plate 523 and the range hood main body 1 together. Thus, the fixed shell 52 moves along with the movable panel 51 in the horizontal direction of the range hood main body 1, thereby effectively preventing the external oil fume from directly entering the range hood main body 1 through the movable panel 51, and further preventing the air in the range hood main body 1 from flowing out through the movable panel 51. In addition, as the movable panel 51 is opened forward, the included angle between the first oil screen 2 and the second oil screen 3 is expanded from the original included angle 103° to 168°. Thus, the area of the air inlet 11 of the range hood is further expanded. The increased area of the air inlet 11 after the air inlet 11 is expanded is 2.5 times that when the air inlet 11 is reduced. Due to the change of the angle during the expansion of the first oil screen 2 and the second oil screen 3, the air inlet 11 of the range hood is lowered and expanded, so that the air inlet 11 is closer to the source of the oil fume during cooking.

[0033] Further, the panel assembly 5 further includes a mounting bracket 54 arranged at the back position of the movable panel 51. The movable panel 51 is hingedly connected with the second oil screen 3 through the mounting bracket 54.
