Drawings
Fig. 1 is a schematic structural diagram of the primary filter with adjustable width of the present invention.
Fig. 2 is an internal structure view of the primary filter with adjustable width of the present invention.
Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1, a width-adjustable primary filter includes two side frames 10 and a filter screen 20, a plurality of connecting rods 30 are disposed between the two side frames 10, the connecting rods 30 are respectively disposed at two ends of the side frames 10, the connecting rods 30 are sequentially connected end to end, the connecting rods 30 are rotatably connected through a movable rotating shaft 31, one end of the connecting rod 30, which is connected to the side frames 10, is connected through the movable rotating shaft 31, the connecting rod 30 is movably connected to the side frames 10, the two side frames 10 and the connecting rods 30 form a rectangular filtering area, the filter screen 20 is disposed in the filtering area, and the periphery of the filter screen 20 is fixedly connected to the side frames 10 and the connecting rods 30, respectively.
The filter screen 20 is made of non-woven fabric or nylon net, the filter screen 20 can be bent, and the part of the filter screen 20 corresponding to the movable rotating shaft 31 is provided with a crease. The filter net 20 may be folded in a curved manner along the fold.
When two side frames 10 are far away from each other and are found to be stretched, the connecting rods 30 are rotatably adjusted through the movable rotating shafts 31, so that the angle between the connecting rods 30 is increased, the distance between the two side frames 10 is changed, the area covered by the filter screen 20 which is fixedly connected with the side frames 10 and the connecting rods 30 and is used for fixing the connecting rods 30 is also increased, and the larger filter area required by the air inlet is met. The maximum filtering area can be set up by 180 degrees between the connecting rod 30 and the connecting rod 30, so that the filtering net 20 is in a flat state to achieve a larger filtering area.
On the contrary, when people need to use at less air intake, extrude two side frames 10 towards the direction that is close to each other to make the angle between two connecting rods 30 diminish, become the M style of calligraphy extrusion between the connecting rod 30, reduce the distance between two side frames 10, make filter screen 20 follow connecting rod 30 and also become the M style of calligraphy extrusion. And when the filter screen 20 is in an M shape, the contact between the filter screen 20 and the air can be increased, and the filtering effect is enhanced.
Adjust through above-mentioned structure to the width of adjustment primary filter, in order to reach and satisfy in the use, different air outlet width sets up.
In the above structure, the filter screen 20 adopts a double-layer structure, and performs double filtration on the air passing through the primary filter, thereby achieving a better filtering effect.
Referring to fig. 2, a reinforcing rod 11 is disposed between two opposite movable rotating shafts 31, two ends of the reinforcing rod 11 are respectively and fixedly connected to the movable rotating shafts 31, the movable rotating shafts 31 are located between two layers of filter screens 20, and the reinforcing rod 11 is fixedly connected to the filter screens 20. The whole strength of the primary filter is enhanced by the reinforcing rods 11, and the filter screen 20 can be prevented from being deformed when receiving large wind.
The utility model provides a just imitate filter of adjustable width is equipped with a plurality of connecting rod between two side frames, and the connecting rod sets up respectively in the both ends of side frame, and the connecting rod is end to end connection in proper order, through activity pivot rotatable coupling between connecting rod and connecting rod. When the two side frames are stretched when being far away from each other, the connecting rods are rotationally adjusted through the movable rotating shafts, so that the angle between the connecting rods is increased, the distance between the two side frames is changed, the area covered by the filter screens for fixing the connecting rods with the side frames and the connecting rods is also increased, and the larger filtering area required by the air inlet is met; on the contrary, when people need use at less air intake, extrude two side frames towards the direction of being close to each other to make the angle between two connecting rods diminish, extrude into the M style of calligraphy between the connecting rod, reduce the distance between two side frames, make the filter screen follow the connecting rod and also become the M style of calligraphy and extrude, thereby adjust primary filter's width, in order to reach and satisfy in the use, different air outlet width sets up.
