[0003] When a traditional filter box is installed, the direction of the air inlet duct is usually fixed, which is not convenient to adjust according to needs, which will affect the convenience of installation to a certain extent. At the same time, the debris filtered out during filtering will often adhere to the filter plate, which will not only affect the air filtering effect of the filter plate, but also require regular cleaning and replacement operations, which will increase the frequency and difficulty of maintenance.

The bottom of the cylindrical box 1 is detachably mounted with a mounting ring 1 9 by bolts, and a mounting ring 2 91 is rotatably mounted on the mounting ring 1 9, and the mounting ring 2 91 is adapted to the air outlet, and a plurality of rotating pins 912 arranged in parallel with each other are rotatably mounted on the inner wall of the mounting ring 2 91, and air guide plates 911 are radially fixedly mounted on the plurality of rotating pins 912, and two adjacent air guide plates 911 are in active contact, and a worm gear 921 is fixedly sleeved on the plurality of rotating pins 912, and a worm 92 is rotatably mounted on the mounting ring 2 91, and the worm 92 is meshed with the plurality of worm gears 921, and can control the synchronous deflection of the plurality of air guide plates 911 when the worm 92 rotates, thereby achieving the air outlet. In order to improve the wind guiding effect, a toothed disc 1 923 is fixedly installed on the bottom side of the mounting ring 1 9, one end of the worm 92 extends to the outside of the mounting ring 2 91 and is fixedly sleeved with a transmission gear 922, which meshes with the toothed disc 1 923 and can control the rotation of the worm 92 when the mounting ring 2 91 rotates, a motor 93 is fixedly installed on the bottom side of the mounting ring 1 9, a driving gear 931 is fixedly sleeved on the output shaft of the motor 93, a toothed disc 2 932 is fixedly installed on the outside of the mounting ring 2 91, the driving gear 931 meshes with the toothed disc 2 932 and can control the rotation of the mounting ring 2 91, so that the direction of the wind outlet can be adjusted with the cooperation of multiple wind guide plates 911; The annular box 4 is fixedly installed on the outside of the cylindrical box 1 and keeps in communication with the cylindrical box 1. It can collect the debris cleaned on the spherical filter plate 3. A discharge port is opened at the bottom of the annular box 4, and an arc-shaped sealing plate 41 is sealed and slidably installed in the discharge port, which can facilitate the operator to discharge the debris in the annular box 4.

[0026] In this embodiment, in order to prevent 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.

[0027] In this embodiment, in order to provide shielding and protection for the motor 93, the driving gear 931, the gear disc 1 923 and the gear disc 2 932, and at the same time avoid the situation where the overall aesthetics are affected by direct exposure, a protective shell 94 is fixedly installed on the bottom side of the mounting ring 1 9, and the protective shell 94 is in active sealing contact with the outer peripheral side of the mounting ring 2 91.

[0028] In this embodiment, in order to facilitate the operator to control the circular plate 22 to slide axially along the air inlet pipe 2, thereby achieving the clamping state between the control limit pin 25 and the limit hole, a handle slidably connected to the air inlet pipe 2 is fixedly installed on the circular plate 22.

[0029] In this embodiment, in order to facilitate the positioning and fixing of the support ring 31 and the spherical filter plate 3, and at the same time to facilitate the disassembly and replacement of them, a mounting groove is opened on the bottom inner wall of the cylindrical box 1, and the semi-ring 32 is movably sealed and clamped in the arc-shaped opening and the mounting groove below. A magnetic block 33 is fixedly installed on the top inner wall of the mounting groove. The semi-ring 32 is made of magnetic material, and the semi-ring 32 and the magnetic block 33 are in an adsorbed and fixed state. A groove is opened on the bottom side of the semi-ring 32, and an arc rod is fixedly installed in the groove.

[0030] Working principle: When in use, first install the device at the desired position and control the circular plate 22 to slide toward the side away from the cylindrical box 1 through the handle, so that the limit pin 25 can be pulled out of the limit hole, and then control the air inlet pipe 2 and adjust the air inlet pipe 2 to a position convenient for connection with the external air duct, and then connect the air inlet pipe 2 with the external air duct to complete the installation.

[0031] After the installation is completed, the power is turned on, and then the motor 93 is turned on. The motor 93 controls the rotation of the installation ring 2 91 through the driving gear 931 and the toothed disc 2 932. At the same time, the worm 92 can be controlled to rotate with the cooperation of the toothed disc 1 923 and the transmission gear 922, so that the deflection of the air guide plate 911 can be controlled with the cooperation of the worm wheel 921 and the rotating pin 912, thereby achieving the purpose of controlling the air guide plate 911 to adjust the wind direction. In order to achieve precise control of the deflection angle of the air guide plate 911, the motor 93 adopts a servo motor.

[0032] When another air guide scheme is needed, the mounting ring 9 is removed from the bottom of the cylindrical box 1. When the air inlet pipe 2 draws air into the cylindrical box 1, it will blow on the spoiler 53, thereby providing drive for the scraper bar 52 and controlling the synchronous rotation of the hollow shaft 5 and the mounting frame 51. The movement of the scraper bar 52 can clean the spherical filter plate 3. The dust and other debris cleaned will fall on the bottom inner wall of the cylindrical box 1 along the outer side of the spherical filter plate 3 and the outer side of the support ring 3 31, and then enter the annular box 4 under the action of the airflow. The air is filtered through the spherical filter plate 3 and then filtered again through the filter material in the filter box 8 before being discharged downward through multiple through holes.

[0033] When the wind direction needs to be adjusted, the electromagnet 76 is energized so that the electromagnet 76 adsorbs the sliding ring 74, thereby controlling the sliding ring 74 to drive the multiple fixed rods 741 to move upward and insert into the corresponding circular holes. At the same time, under the action of the circular ring, the limit ring 75 can be prevented from falling off the rotating shaft 73, thereby driving the rotating shaft 73 to rotate when the hollow shaft 5 rotates, and then controlling the rotation of the reciprocating screw rod 72. The rotation of the reciprocating screw rod 72 can control the up and down reciprocating movement of the sliding frame 71. Since the bottom side of the sliding frame 71 is hingedly mounted on the circular block, and the ends of the multiple semi-rigid support rods 6 that are close to each other are hingedly mounted on the circular block, the multiple semi-rigid support rods 6 can be controlled to perform reciprocating deformation, thereby achieving the effect of adjusting the directions of the multiple through holes, and at the same time, the power transmission between the hollow shaft 5 and the rotating shaft 73 is controlled by controlling the switch of the solenoid valve.

[0034] When the spherical filter plate 3 needs to be replaced, the semi-ring 32 is pulled downward by controlling the arc rod to disengage the magnetic block 33 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 at the bottom in a rotating manner. Then, the new spherical filter plate 3 is replaced and then installed into the cylindrical box 1 from the arc-shaped opening at the bottom. The arrangement 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 working stability of the spherical filter plate 3 and the support ring three 31 without affecting 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 in and put in from the arc-shaped opening at the bottom, the vertical projection of the arc-shaped opening at the bottom is arranged in a 1 / 2 ring shape.

[0035] 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 driving gear 931, the gear plate 1 923 and the gear plate 2 932, but also avoid the potential safety hazards and aesthetic problems caused by direct exposure.

[0036] Embodiment 2 On the basis of the first embodiment, we further optimized the structural design of the filter box, and especially made significant improvements to its installation and maintenance convenience.

[0037] Reference Fig.10 and Fig.11First, we introduced a mounting tube 10 with a convex cross-section, a mounting frame 101 is fixedly installed at the bottom of the mounting tube 10, and a mounting opening with the same inner diameter as the mounting tube 10 is opened on the mounting frame 101. Secondly, an opening and closing door 102 in a rectangular frame shape is hingedly installed at the bottom of the mounting frame 101, and a grille plate 103 is fixedly installed on the opening and closing door 102 by bolts.
