[0053] In the embodiment, in order to avoid the sliding ring 74 from being separated from the rotating shaft 73, a circular ring is fixedly installed on the outer top end of the rotating shaft 73.

[0054] In the embodiment, in order to realize the shielding protection of the motor 93, the drive gear 931, the toothed disc one 923 and the toothed disc two 932, and avoid affecting the overall aesthetics due to direct exposure, a protective shell 94 is fixedly installed on the bottom side of the mounting ring one 9, and the protective shell 94 is in movable and sealing contact with the outer circumferential side of the mounting ring two 91.

[0055] In the embodiment, in order to facilitate the operator to control the circular plate 22 to slide along the axis of the air inlet pipe 2, so as to control the clamping state between the limiting pin 25 and the limiting hole, a handle is fixedly installed on the circular plate 22 and is in sliding connection with the air inlet pipe 2.

[0056] In this embodiment, in order to facilitate positioning and fixing of the support ring three 31 and the spherical filter plate 3, and at the same time achieve the effect of facilitating disassembly and replacement, an installation groove is formed on the inner wall of the bottom of the cylindrical box 1, a semi-ring 32 is movably and sealingly clamped and installed in the arc-shaped opening and the installation groove below, a magnetic block 33 is fixedly installed on the top inner wall of the installation groove, the material of the semi-ring 32 is magnetic material, and the semi-ring 32 and the magnetic block 33 are in an adsorbed fixed state. A recess is formed on the bottom side of the semi-ring 32, and an arc-shaped rod is fixedly installed in the recess.

[0057] Working principle: in use, first install the device at the required position, and control the circular plate 22 to slide away from the cylindrical box 1 by the handle, so that the limiting pin 25 can be pulled out of the limiting hole, then control the air inlet pipe 2 and adjust the air inlet pipe 2 to a position convenient for connecting with the external air pipe, then connect the air inlet pipe 2 with the external air pipe, so as to complete the installation.

[0058] After installation, connect the power supply, then start the motor 93, the motor 93 controls the rotation of the installation ring two 91 through the driving gear 931 and the second gear disc 932, and controls the rotation of the worm 92 under the cooperation of the first gear disc 923 and the transmission gear 922, so as to control the deflection of the air deflector 911 under the cooperation of the worm gear 921 and the rotating pin 912, thereby achieving the purpose of controlling the air deflector 911 to adjust the wind direction. In order to realize accurate control of the deflection angle of the air deflector 911, the motor 93 adopts a servo motor.

[0059] When another air guiding scheme is needed, the installation ring one 9 is removed from the bottom of the cylindrical box 1. When the air inlet pipe 2 blows air into the cylindrical box 1, it will blow on the spoiler 53, thereby providing driving force for the scraping strip 52 and controlling the synchronous rotation of the hollow shaft 5 and the mounting frame 51. The movement of the scraping strip 52 can clean the spherical filter plate 3. The dust and other impurities cleaned will fall on the inner wall of the bottom of the cylindrical box 1 along the outer side of the spherical filter plate 3 and the outer side of the support ring three 31, and then under the action of the airflow, it can enter the annular box 4. After the air is filtered by the spherical filter plate 3 and then filtered again by the filter material in the filter material box 8, it is discharged downward through the plurality of through holes.

[0060] When the wind direction needs to be adjusted, the electromagnet 76 is powered on, so that the electromagnet 76 adsorbs the sliding ring 74, so that the sliding ring 74 can drive the plurality of fixed rods 741 to move upward and insert into the corresponding circular hole, and under the action of the circular ring, the limiting ring 75 can be prevented from falling off the rotating shaft 73, so that the rotating shaft 73 can be driven to rotate when the hollow shaft 5 rotates, and the reciprocating screw rod 72 can be controlled to rotate. The rotation of the reciprocating screw rod 72 can control the up-down reciprocating movement of the sliding frame 71. Since the bottom side of the sliding frame 71 is hingedly installed on the circular block, and the ends of the plurality of semi-rigid supporting rods 6 close to each other are hingedly installed on the circular block, the plurality of semi-rigid supporting rods 6 can be controlled to deform reciprocatingly, thereby achieving the effect of adjusting the orientation of the plurality of through holes. At the same time, the control of power transmission between the hollow shaft 5 and the rotating shaft 73 is realized by controlling the opening and closing of the electromagnetic valve.

[0061] When the spherical filter plate 3 needs to be replaced, the arc-shaped rod controls the semi-ring 32 to be pulled down, so that the magnetic block 33 is disconnected from the semi-ring 32, thereby controlling the support ring three 31 and the spherical filter plate 3 to be taken out from the arc-shaped opening below in a rotating manner, and then the new spherical filter plate 3 is installed in the cylindrical box 1 from the arc-shaped opening below. The setting of the magnetic block 33 and the semi-ring 32 made of magnetic material can ensure the stability of the support ring three 31 and the spherical filter plate 3 after installation, which can ensure the stability of the spherical filter plate 3 and the support ring three 31, and does not affect the quick disassembly and assembly of the support ring three 31 and the spherical filter plate 3. In order to ensure that the support ring three 31 and the spherical filter plate 3 can be smoothly taken out from the arc-shaped opening below, the vertical projection of the arc-shaped opening below is set as 1 / 2 ring.

[0062] During the operation of the entire device, the setting of the protective shell 94 can not only provide shielding protection for the motor 93, the drive gear 931, the toothed disc one 923 and the toothed disc two 932, but also avoid safety hazards and aesthetic problems caused by direct exposure.
