[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1 - 2, an embodiment provided by the present utility model: an adjustable filter, including a housing 1 for connecting various components. The top of the housing 1 is fixedly connected with a top cover 2 through bolts for cooperating with the housing 1. The front and rear sides of the top cover 2 are both fixed to the housing 1 through bolts, which facilitates positioning the position of the indicator 21 on its top. A hole adapted to the adjusting block 31 is provided in the middle of the top cover 2. A filter element 4 is arranged inside the housing 1 for filtering. An adjusting member 3 is arranged above the filter element 4 for adjusting the shielding degree between a plurality of baffle plates 34 and a plurality of vertical plates 45 to adjust the intake air volume of the filter element 4, thereby changing the outlet air volume of the device. The middle part of the bottom surface of the housing 1 is fixedly connected with an air outlet pipe 12 for discharging the filtered gas. The front and rear parts of the bottom surface of the housing 1 are both fixedly connected with air inlet pipes 11 for introducing gas. The lower part of the inner wall of the housing 1 is fixedly connected with a support seat 13 for cooperating with the installation of the filter element 4. The upper left and right sides of the outer wall of the support seat 13 are both fixedly connected with fixing plates 14 for cooperating with the positioning columns 15. The top of the fixing plate 14 is fixedly connected with a positioning column 15 for positioning the limiting plate 42.

[0033] As Figures 3 - 5 shown, a plurality of groups of indicators 21 are fixedly connected to the middle part of the top surface of the top cover 2. One group consists of three lines with gradually decreasing lengths in sequence, and the distance between each line is the same, for displaying the size of the outlet air volume after adjustment. The adjusting member 3 includes a top plate 33. The middle part of the top surface of the top plate 33 is fixedly connected with an adjusting block 31 for driving the top plate 33 to rotate. The adjusting block 31 penetrates through the top cover 2 and is movably connected therewith. An arrow 32 is fixedly connected to the left side of the adjusting block 31, which is used to display the position of the clamping flap 35 and cooperate with the indicator 21 to display the adjustment degree. A plurality of baffle plates 34 are fixedly connected to the middle part of the bottom surface of the top plate 33, which can shield the gap between the vertical plates 45 to adjust the size of the intake air volume, thereby controlling the outlet air volume. A connecting flap 36 is fixedly connected to the left side of the bottom surface of the top plate 33, which has a certain deformation ability and can control the clamping flap 35 to move up and down to a certain extent to cooperate with the clamping flap 35 to be clamped into the groove between two inclined blocks 44. A clamping flap 35 is fixedly connected to the lower part of the connecting flap 36 for cooperating with the inclined block 44 to limit the position of the adjusted adjusting member 3.

[0034] Further, the filter element 4 includes two connecting rings 41 for connecting various components. A filter element 46 is fixedly connected between the two connecting rings 41 for filtering. A plurality of vertical plates 45 are arranged inside the filter element 46 for cooperating with the baffle 34 to control the air output. The upper and lower ends of the plurality of vertical plates 45 are respectively fixedly connected to the two connecting rings 41. On the left and right sides of the outer wall of the lower connecting ring 41, limiting plates 42 are fixedly connected for positioning and limiting the position of the filter element 4. The positioning post 15 passes through the limiting plate 42 and is movably connected thereto. A connecting groove 43 is formed on the top surface of the upper connecting ring 41 for cooperating with the connection of the clamping flap 35. A plurality of inclined blocks 44 are fixedly connected to the lower part of the inner wall of the connecting groove 43. Their shape is similar to a triangular prism. One side has a relatively gentle slope angle and the other side has a relatively vertical slope angle for cooperating with the clamping flap 35 so that the adjusting block 31 can only rotate when the clamping flap 35 moves in the direction of the relatively gentle surface. When moving in the opposite direction, the clamping flap 35 will be stuck. A groove can be formed between every two adjacent inclined blocks 44 to cooperate with the limitation of the clamping flap 35.

[0035] Working principle: During use, when it is necessary to adjust the air output of the filter, rotate the adjusting block 31 to drive the top plate 33 to rotate. When the top plate 33 rotates, the connecting flap 36 connected thereto will move accordingly. Since the clamping flap 35 connected to the connecting flap 36 will move in position accordingly when the connecting flap 36 moves, it will move along the relatively gentle slope of the inclined block 44. The top plate 33 connected to the adjusting block 31 will drive the baffle 34 to rotate accordingly, thereby blocking the gap between the two vertical plates 45. At this time, the arrow 32 on the adjusting block 31 will turn towards the indicator 21 on the top cover 2. According to the prompt of the indicator 21, when the appropriate air output is adjusted, the rotation of the adjusting block 31 can be stopped. At this time, under the elastic action of the connecting flap 36, the connecting flap 36 will return to its original shape and drive the clamping flap 35 to be stuck between the grooves formed by the two inclined blocks 44, thereby fixing the position of the adjusting member 3, and the adjustment of the air output of the filter can be completed.

[0036] When it is necessary to replace the filter element 4, loosen the bolts between the housing 1 and the top cover 2, then remove the top cover 2, then take out the adjusting member 3 from the filter element 4, then lift the filter element 4 upward to drive the limiting plate 42 to disengage from the positioning post 15, then align the limiting plate 42 at the lower part of the new filter element 4 with the positioning post 15 and press it down to position the filter element 4, then insert the plurality of baffles 34 at the lower part of the adjusting member 3 into the filter element 4, place the top plate 33 on the upper connecting ring 41, make the clamping flap 35 be stuck in the groove formed between the plurality of inclined blocks 44 in the connecting groove 43, then cover the top cover 2 on the housing 1, make the adjusting block 31 pass through the hole in the middle of the top cover 2, and then fix the top cover 2 and the housing 1 with bolts.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
