The two side walls of the accommodating groove 22 are provided with through grooves corresponding to the positions of the pressing plates 311, the inner top wall of each through groove is level with the top wall of each vertical groove, and the inner bottom wall of each through groove is level with the top surface of the dust filter net 1 inserted into the slot 21. Both ends of the pressing plate 311 are respectively fixed with the vertical sections 3142 of the corresponding ends through the corresponding end through grooves. When the upper end of the dust filtering net 1 is limited by the pressing plate 311, the pressing plate 311 is supported by the two vertical sections 3142, and meanwhile, the pressing plate 311 is also supported by the inner bottom wall of the through groove, so that the pressing plate 311 is more stable.

The length of roof 312 is less than the length of slot 21, and the upper and lower end of passageway 5 communicates with slot 21 and spacing groove 4 respectively has been seted up to the position that protecgulum 2 corresponds the roof 312 board, and roof 312 is located under filter screen 1 for roof 312 upwards moves at passageway 5 through rotating knob 33, through with filter screen 1 bottom surface contact, thereby ejecting filter screen 1 slot 21, and filter screen 1 takes more conveniently after ejecting.

The distance between the top surface of the top plate 312 and the bottom surface of the dust screen 1 is greater than the depth of the slot 21, and the distance between the top surface of the top plate 312 and the bottom wall of the accommodating groove 22 is the same as the upward moving distance of the connecting part 314, before the top plate 312 moves upward to contact the dust screen 1, the transverse part 3141 drives the upper pressing plate 311 to move upward, the upper pressing plate 311 is separated from the upper surface of the dust screen 1, the limiting fixing effect on the dust screen 1 is released, when the top plate 312 moves upward to contact the dust screen 1 until the connecting part 314 moves upward, the connecting part 314 drives the pressing plate 311 to move upward, and when the upper surface of the top plate 312 is flush with the inner bottom wall of the accommodating groove 22, the transverse part 3141 moves upward to the top end of the transverse part 3141 corresponding to the limiting groove 4, so as to be limited, and at this time, the connecting part 314 cannot move upward at the maximum, so that the top plate 312 and the sliding block 313 cannot move upward, and the rotating rod 322 which is in threaded connection with the sliding block 313 cannot rotate, so that the knob 33 cannot rotate, and the knob 33 cannot rotate to indicate that the dust screen 1 is ejected from the slot 21. At this time, a gap is formed between the upper surface of the dust filter net 1 and the lower pressing plate 311, so that the dust filter net 1 can be conveniently taken out.

The pressing plate 311 is trapezoid, and the length of the upper top surface is smaller than that of the lower bottom surface, so that the pressing plate 311 can enter the channel 5 more easily, and the situation that the pressing plate 311 is blocked by the front covers 2 at two sides of the channel 5 is prevented.

An auxiliary limiting plate 6 is fixed on the side face of the pressing plate 311, and the outer side face of the auxiliary limiting plate 6 is attached to the inner side face of the dust filtering net 1. The auxiliary limiting plate 6 limits the inner side surface of the dust filtering net 1, so that the dust filtering net 1 is positioned in the front cover 2 more stably.

In summary, when the dust filter net 1 is detached, the front cover 2 is released from the fixing, and then the front cover 2 is rotated so that the inner side surface of the front cover 2 faces the operator. By rotating the knob 33 to rotate the rotating rod 322, the rotating rod 322 rotates to enable the sliding block 313 to move upwards in the sliding groove 331, the sliding block 313 drives the transverse segment 3141 to move upwards, the transverse segment 3141 drives the top plate 312 fixed with the transverse segment 3141 and the two vertical segments 3142 to move upwards, and the vertical segments 3142 drive the pressing plate 311 to move upwards. The pressing plate 311 drives the auxiliary limiting plate 6 to move upwards, before the top plate 312 contacts the dust filter net 1, the pressing plate 311 leaves the top surface of the dust filter net 1, and the auxiliary limiting plate 6 leaves the inner side surface of the dust filter net 1, so that a space for taking the dust filter net 1 is formed between the auxiliary limiting plate 6 and the dust filter net 1. After the upper surface of the top plate 312 contacts with the lower surface of the dust filter net 1, the top plate 312 continues to move upward, lifting the dust filter net 1 upward until the dust filter net 1 is lifted out of the slot 21, so that the lower surface of the dust filter net 1 is level with the inner bottom wall of the accommodation groove 22. In this process, the horizontal segment 3141, the vertical segment 3142, the pressing plate 311 and the auxiliary limiting plate 6 also follow the top plate 312 to move upward, so that the space for taking the pressing plate 311 and the auxiliary limiting plate 6 with the dust filter net 1 is not reduced, and the dust filter net 1 is convenient to take out. The dust filter net 1 is inclined towards the outer side of the front cover 2 under the guidance of the slot 21, so that the dust filter net 1 is not easy to topple when the limit is lost, and when the dust filter net 1 is ejected out of the slot 21, the transverse section 3141 contacts with the top wall of the limit groove 4 corresponding to the section, so that the top plate 312 fixed with the transverse section 3141 stops moving upwards, the top plate 312 stops moving upwards, the sliding block 313 stops rotating the rotating rod 322, and the knob 33 connected with the rotating rod 322 stops rotating. The rotation of knob 33 stops to indicate that top plate 312 has pushed dust filter net 1 out of slot 21, and dust filter net 1 in receiving slot 22 can be removed.

In the process of installing the dust filter net 1, the dust filter net 1 is directly placed in the accommodating groove 22, at this time, the dust filter net 1 is supported by the top plate 312, and as the knob 33 is rotated, the slider 313 in threaded connection with the rotating rod 322 moves down, thereby driving the top plate 312 to move down, the top plate 312 moves down, the dust filter net 1 enters the slot 21 under the action of gravity, and in the process of entering the slot 21, the dust filter net 1 gradually assumes a vertical state under the guidance of the slot 21. When the dust filter net 1 completely enters the slot 21, the knob 33 is continuously rotated, the sliding block 313 moves downwards to drive the top plate 312 to move downwards, the top plate 312 drives the horizontal segment 3141 and the vertical segment 3142 to move downwards, and the vertical segment 3142 drives the pressing plate 311 and the auxiliary limiting plate 6 to move downwards. When the transverse segment 3141 contacts with the bottom wall of the limit groove 4, the knob 33 stops rotating, at this time, the pressing plate 311 contacts with the upper surface of the dust filter net 1, the auxiliary limit plate 6 contacts with the inner side surface of the dust filter net 1, the pressing plate 311 limits the upper side of the dust filter net 1, the dust filter net 1 cannot move upwards, and the auxiliary limit plate 6 limits the inner side surface of the dust filter net 1, so that the dust filter net 1 is more stable. The disassembly and the assembly of the dust filter net 1 are realized by rotating the knob 33, so that the disassembly and the assembly are more convenient.
