The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides an air suction cover with adjustable air suction area, includes the air suction cover body, its characterized in that:
at least one group of horizontally distributed panels are arranged inside the opening at the bottom of the air suction cover body, and at least one side edge of each panel is close to the edge of the opening of the air suction cover body and is fixedly connected or slidably connected with the inner wall of the air suction cover body.
Two opposite side outsides that the panel is close to the opening edge of the cover body that induced drafts are equipped with rather than the at least a set of slider of being connected, and the slider that is located same side slides and sets up on same guide rail, just the guide rail tip respectively through the end socket with the interior wall connection of the cover body that induced drafts is fixed.
The panels are provided with at least two groups, and the panels are mutually distributed in parallel or vertically.
The air suction cover body comprises an air suction pipe positioned at the top, a conical section positioned at the middle part and a vertical section positioned at the bottom, and the inner wall of the vertical section is provided with a panel connected with the vertical section.
The bottom surface of the panel positioned at the bottom end is of an inverted cone structure.
The utility model has the advantages that: structural design is reasonable, through setting up the panel that can move about for the opening size and the opening position of cover body bottom of induced drafting all can obtain the adjustment, can concentrate on operation point position upper portion, is used for making local negative pressure effect increase through the adjustment area of induced drafting, has ensured the collection effect of waste gas.

In the figure: 100 air suction cover bodies, 101 conical sections, 102 vertical sections, 103 air suction pipes, 200 panels, 301 end seats, 302 guide rails and 303 sliding blocks.
Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Example one
According to the description of fig. 1 to 4: the embodiment provides an air suction hood with an adjustable air suction area, which comprises an air suction hood body 100, wherein the air suction hood body 100 comprises an air suction pipe 103 positioned at the top, a conical section 101 positioned at the middle part and a vertical section 102 positioned at the bottom, the air suction pipe 103 is used for being connected with a waste gas collecting pipeline, and the interior of the vertical section 102 is used for being assembled with a panel 200;
two groups of horizontally distributed panels 200 are arranged inside an opening at the bottom of the air suction hood body 100, the panels 200 are arranged one above the other, a gap between the panels 200 and the opening is 0.2-0.5cm, the side edges of the front side and the rear side of each of the two groups of panels 200 are respectively arranged close to the edge of the opening of the air suction hood body 100, two groups of sliders 303 connected with the panels 200 are arranged outside the side edges of the front side and the rear side of each of the panels 200, the sliders 303 are respectively positioned at the two end parts of the side edge where the sliders 303 are positioned, the sliders 303 positioned on the same side edge are arranged on the same guide rail 302 in a sliding manner, the guide rail 302 is a cylindrical guide rail 302 and penetrates through the sliders 303 to be connected in a sliding manner, the end parts of the guide rail 302 are respectively connected and fixed with the inner wall of the air suction hood;
further, the bottom of the lower panel 200 is a conical structure, and the conical structure is a rectangular pyramid, and is used for guiding the rising exhaust gas, so that the exhaust gas enters the opening position at the bottom of the suction hood body 100 and is collected;
when the air suction hood with the structure is used, the two groups of panels 200 can be independently arranged in a left-right sliding mode, when the two groups of panels 200 are overlapped, the opening area of the opening of the air suction hood body 100 is the largest, when the two groups of panels 200 are distributed in a crossed mode or are adjacent in edge, the corresponding opening area is changed, meanwhile, the opening position between the edge of the panel 200 and the inner wall of the air suction hood body 100 is adjusted by sliding the two groups of panels 200 leftwards or rightwards, the position is used as a main waste gas collecting opening, a strip-shaped gap opening is further arranged between the edge of the panel 200 and the inner wall of the air suction hood body 100 and used for collecting waste gas at the edge of the air suction hood body 100, at the moment, as the power of an external draught fan is not changed, when the opening area of the air suction hood body 100 is reduced, the negative pressure effect corresponding to the opening, the phenomenon that partial waste gas cannot be collected due to small suction force is avoided.
Example two
According to FIG. 5: the embodiment provides an air suction hood with adjustable air suction area, which comprises an air suction hood body 100 and two groups of panels 200, and the difference from the first embodiment is that:
wherein the front side and the rear side of a set of panel 200 and the inner wall sliding connection of the cover body 100 that induced drafts, and the left and right sides and the right side of another set of panel 200 and the inner wall sliding connection of the cover body 100 that induced drafts for distribute perpendicularly between two sets of panels 200, at this moment, through sliding panel 200, make the open position of the cover body 100 bottom that induced drafts adjust more in a flexible way, can be located arbitrary one corner department of the cover body 100 that induced drafts, be convenient for adjust according to the operation position.
The above is only the preferred embodiment of the present invention, as long as the preferred embodiment is realized by the same means, the objective technical solution of the present invention all belongs to the protection scope of the present invention.
