[0008] The purpose of this invention is to design an intelligent air purifier to solve the above problems in the prior art. Summary of the Invention

[0013] A cleaning device is provided on the inner wall of the housing and between the high-voltage electrostatic dust removal and sterilization air purification device and the elastic wave-shaped filter screen;

[0014] The cleaning device includes a bracket, which is arranged on the inner wall of the shell and is located between the high-voltage electrostatic dust removal and sterilization air purification device and the elastic wavy filter screen, a self-rotating disc is rotatably provided at the middle position of the bottom end surface of the bracket, and a rotating driving member is provided between the self-rotating disc and the bracket; a movable column, one end of the movable column is arranged on the self-rotating disc for rotation up and down, the axis of the movable column is arranged at a preset angle to the horizontal plane, an up and down driving member is provided between one end of the movable column and the self-rotating disc, a placement groove is provided in the movable column, a telescopic member is provided on the movable column and located in the placement groove, the telescopic end of the telescopic member passes through the movable column, and a sphere is provided at the telescopic end of the telescopic member and located outside the movable column, and the sphere is located between the crest and the trough of the elastic wavy filter screen;

[0015] With the cooperation of the rotating drive part, the rotating disk, the telescopic part, the upper and lower drive parts, and the movable column, the sphere periodically revolves around the rotating disk for several circles. The diameter of the sphere revolving around the rotating disk decreases as the number of rotations of the rotating disk increases. Each time the sphere revolves around the rotating disk, it passes through the position between the crest and the trough of the elastic wave-shaped filter screen, so that when the sphere passes through the position between the crest and the trough of the elastic wave-shaped filter screen, the crest of the elastic wave-shaped filter screen is first hit and then elastically deformed. When the sphere passes through the position between the crest and the trough of the elastic wave-shaped filter screen, the trough of the elastic wave-shaped filter screen is first pulled and then elastically deformed.

[0016] Furthermore, a rolling device is provided between the sphere and the telescopic end of the telescopic member;

[0017] The rolling-through device is used to allow the ball to roll through the position between the crests and troughs of the elastic wavy filter when the ball passes through the position between the crests and troughs of the elastic wavy filter, so as to reduce the friction between the ball and the elastic wavy filter.

[0018] Furthermore, the rolling-through device includes a connecting block, which is arranged between the sphere and the telescopic end of the telescopic member, and the sphere is universally connected to the connecting block.

[0019] Furthermore, the rotation driving member includes a first rotation motor, a fixed end of the first rotation motor is arranged at a middle position of the bottom end surface of the bracket, and a rotating end of the first rotation motor is transmission-connected to the rotating disk.

[0020] Furthermore, the upper and lower driving members include two connecting plates, the two connecting plates are arranged on the bottom end surface of the rotating disk, the two connecting plates are symmetrically arranged, and a linkage shaft is rotatably arranged between the two connecting plates, and a second rotating motor is arranged on one of the connecting plates, and the rotating end of the second rotating motor is transmission-connected to the linkage shaft, and one end of the movable column is connected to the linkage shaft and is located between the two connecting plates.

[0021] Furthermore, the bottom end surface of the shell is open and not sealed, and the bottom end surface of the shell is detachably provided with an opening and closing plate;

[0022] When the cleaning device and the fan are not working and there are large particles and / or strips on the elastic wave filter screen on the opening and closing plate, operate the opening and closing plate to separate from the shell to remove the large particles and / or strips on the opening and closing plate from the shell.

[0023] Furthermore, a PM2.5 sensor, a virus sensor, a bacteria sensor, a formaldehyde sensor, a temperature sensor, and a humidity sensor are provided on the inner wall of the shell and below the elastic wave-shaped filter.

[0024] Furthermore, it further comprises a contact plate, one end of which is arranged at the bottom end of the movable column, and the other end of which extends to the axis of the rotating disk;

[0025] During the period when the sphere periodically revolves around the rotating disk for several circles, the abutment plate does not contact the elastic wave-shaped filter screen, thereby preventing the elastic wave-shaped filter screen from being worn during the period when the abutment plate revolves around the rotating disk for several circles;

[0026] After the sphere periodically revolves around the rotating disk for several circles, the retractable end of the telescopic part is shortened to the shortest, the upper and lower driving parts drive one end of the movable column to rotate up and down periodically, and the rotating driving part drives the rotating disk to rotate periodically by a predetermined angle until it completes one circle, so that the abutment plate revolves around the rotating disk once and periodically abuts against several wave crests of the elastic wave-shaped filter screen during the period when the abutment plate revolves around the rotating disk once.

[0027] Therefore, the present invention provides the following effects and / or advantages:

[0028] 1) The fan is used to drive the air outside the shell to first enter the shell from a number of air inlets, and then pass through the elastic wave-shaped filter, the cleaning device, the high-voltage electrostatic dust removal and sterilization air purification device in sequence, and then be discharged from the shell from a number of air outlets; the several air inlets are used to allow the air outside the shell to enter the shell from a number of air inlets when the fan is working; the high-voltage electrostatic dust removal and sterilization air purification device is used to sterilize the microorganisms in the air and adsorb the particulate matter in the air after the air enters the shell from a number of air inlets; the elastic wave-shaped filter is used to intercept large particulate matter and / or strip-shaped objects in the air before the air enters the shell from a number of air inlets and is processed by the high-voltage electrostatic dust removal and sterilization air purification device, so as to extend the service life and cleaning cycle of the high-voltage electrostatic dust removal and sterilization air purification device; the several air outlets are used to discharge the air treated by the high-voltage electrostatic dust removal and sterilization air purification device to the outside of the shell.

[0029] When the fan is not working, the rotating driving member drives the rotating disc to rotate several times and stops for a predetermined time after each rotation of the rotating disc; during each stop of the rotating driving member driving the rotating disc, the telescopic end of the telescopic member is shortened by a predetermined amount, and the upper and lower driving members drive one end of the movable column to rotate downward by a predetermined angle, so that the ball is located between the crest and the trough of the elastic wave-shaped filter before the rotating driving member drives the rotating disc to rotate next time, so that the diameter of the ball revolving around the rotating disc decreases as the number of rotations of the rotating disc increases.

[0030] With the cooperation of the rotating drive part, the rotating disk, the telescopic part, the upper and lower drive parts and the movable column, the sphere periodically rotates around the rotating disk for several times, the diameter of the sphere rotating around the rotating disk decreases as the number of rotations of the rotating disk increases, and the sphere passes through the position between the crest and the trough of the elastic wave-shaped filter each time it rotates around the rotating disk, so that when the sphere passes through the position between the crest and the trough of the elastic wave-shaped filter, the crest of the elastic wave-shaped filter is first hit and then elastically deformed, so that the large particles and / or strips at the crest of the elastic wave-shaped filter are first quickly separated and then the remaining large particles and / or strips are gradually separated, so that when the sphere passes through the position between the crest and the trough of the elastic wave-shaped filter, the trough of the elastic wave-shaped filter is first pulled and then elastically deformed, so that the large particles and / or strips at the trough of the elastic wave-shaped filter are first quickly separated and then the remaining large particles and / or strips are gradually separated.

[0031] To sum up: when the fan is not working, there is no need to manually clean the elastic wave-shaped filter and the large particles and / or strips on the elastic wave-shaped filter can be cleaned circle by circle from the outside to the inside; when cleaning circle by circle, the large particles and / or strips at the crest of the elastic wave-shaped filter can be quickly detached first and then the remaining large particles and / or strips can be detached one after another, and the large particles and / or strips at the trough of the elastic wave-shaped filter can be quickly detached first and then the remaining large particles and / or strips can be detached one after another; before the elastic wave-shaped filter intercepts the large particles and / or strips in the air entering the shell from several air inlets next time, the interception efficiency and interception quality of the elastic wave-shaped filter can be restored, and the interception efficiency and interception quality of the elastic wave-shaped filter can be greatly reduced next time.

[0032] 2) The rolling device is used to allow the ball to roll through the position between the crests and troughs of the elastic wavy filter when the ball passes through the position between the crests and troughs of the elastic wavy filter, so as to reduce the friction between the ball and the elastic wavy filter, thereby reducing the damage caused by the ball to the elastic wavy filter, thereby extending the service life of the elastic wavy filter while cleaning large particles and / or strips on the elastic wavy filter.

[0033] 3) When the cleaning device and the fan are not working and there are large particles and / or strips on the elastic wavy filter screen on the opening and closing plate, operate the opening and closing plate to separate from the shell to remove the large particles and / or strips on the opening and closing plate from the shell, thereby preventing the air from driving the large particles and / or strips on the opening and closing plate to flow toward the elastic wavy filter screen when the fan drives the air outside the shell to enter the shell through the several air inlets next time, thereby reducing the interception efficiency and interception quality of the elastic wavy filter screen for the large particles and / or strips in the air entering the shell through the several air inlets.

[0034] 4) During the period when the sphere periodically revolves around the rotating disk for several circles, the abutment plate does not contact the elastic wavy filter screen, so as to prevent the abutment plate from causing wear to the elastic wavy filter screen during the period when the sphere periodically revolves around the rotating disk for several circles.

[0035] After the sphere periodically revolves around the rotating disk for several circles, the retractable end of the retractable part is shortened to the shortest, the upper and lower driving parts drive one end of the movable column to rotate up and down periodically, and the rotating driving part drives the rotating disk to rotate periodically by a predetermined angle until it completes one circle, so that the same abutment plate revolves around the rotating disk once and periodically abuts against several wave crests of the elastic wave-shaped filter screen during the period when the same abutment plate revolves around the rotating disk once, thereby allowing large particles and / or strips at several wave crests and several wave troughs of the elastic wave-shaped filter screen to quickly detach at the same time.

[0036] In summary: when the fan is not working and the large particles and / or strips on the elastic wave filter are cleaned from the outside to the inside, the large particles and / or strips in the middle of the elastic wave filter can be cleaned centrally. During the centralized cleaning, the large particles and / or strips at several peaks and troughs of the elastic wave filter can be quickly removed at the same time.

[0037] Before the elastic wave filter intercepts large particles and / or strips in the air entering the shell through several air inlets next time, the interception efficiency and interception quality of the elastic wave filter can be greatly restored, and the interception efficiency and interception quality of the elastic wave filter can be prevented from being greatly reduced next time.

[0051] The fan 6 is used to drive the air outside the shell 1 to first enter the shell 1 through several air inlets 2, and then pass through the elastic wave-shaped filter 4, the cleaning device, the high-voltage electrostatic dust removal and sterilization air purification device 5 in sequence, and then be discharged from the shell 1 through several air outlets 3; several of the air inlets 2 are used to allow the air outside the shell 1 to enter the shell 1 through several air inlets 2 when the fan 6 is working; the high-voltage electrostatic dust removal and sterilization air purification device 5 is used to sterilize the microorganisms in the air and adsorb the particulate matter in the air after the air enters the shell 1 through several air inlets 2; the elastic wave-shaped filter 4 is used to intercept large particles and / or strips in the air before the air enters the shell 1 through several air inlets 2 and is processed by the high-voltage electrostatic dust removal and sterilization air purification device 5, so as to extend the service life and cleaning cycle of the high-voltage electrostatic dust removal and sterilization air purification device 5; several of the air outlets 3 are used to discharge the air treated by the high-voltage electrostatic dust removal and sterilization air purification device 5 to the outside of the shell 1.

[0052] When the fan 6 is not working, the rotating driving member drives the rotating disc 8 to rotate several times and stops for a predetermined time after each rotation of the rotating disc 8; during each stop of the rotating driving member driving the rotating disc 8, the telescopic end of the telescopic member 11 is shortened by a predetermined amount, and the upper and lower driving members drive one end of the movable column 9 to rotate downward by a predetermined angle, so that the ball 12 is located between the crest and the trough of the elastic wave-shaped filter screen 4 before the rotating driving member drives the rotating disc 8 to rotate next time, so that the diameter of the ball 12 revolving around the rotating disc 8 decreases as the number of rotations of the rotating disc 8 increases;

[0053] Under the cooperation of the rotating drive member, the rotating disk 8, the telescopic member 11, the upper and lower driving members, and the movable column 9, the sphere 12 periodically revolves around the rotating disk 8 for several circles. The diameter of the sphere 12 revolving around the rotating disk 8 decreases as the number of rotations of the rotating disk 8 increases. Each time the sphere 12 revolves around the rotating disk 8, it passes through the position between the crest and the trough of the elastic wave-shaped filter 4, so that the crest of the elastic wave-shaped filter 4 is hit first when the sphere 12 passes through the position between the crest and the trough of the elastic wave-shaped filter 4. Then elastic deformation occurs, so that the large particles and / or strips at the crest of the elastic wave-shaped filter 4 are quickly separated first and then the remaining large particles and / or strips are separated one after another, so that when the sphere 12 passes through the position between the crest and the trough of the elastic wave-shaped filter 4, the trough of the elastic wave-shaped filter 4 is first pulled and then elastic deformation occurs, so that the large particles and / or strips at the trough of the elastic wave-shaped filter 4 are quickly separated first and then the remaining large particles and / or strips are separated one after another;

[0054] When the fan 6 is not working, there is no need to manually clean the elastic wave-shaped filter screen 4, and large particles and / or strips on the elastic wave-shaped filter screen 4 can be cleaned circle by circle from the outside to the inside; when cleaning circle by circle, large particles and / or strips at the wave crests of the elastic wave-shaped filter screen 4 can be quickly separated first, and then the remaining large particles and / or strips can be separated one by one; large particles and / or strips at the wave troughs of the elastic wave-shaped filter screen 4 can be quickly separated first, and then the remaining large particles and / or strips can be separated one by one;

[0055] Before the elastic wave-shaped filter 4 intercepts the large particles and / or strips in the air entering the shell 1 through the several air inlets 2 next time, the interception efficiency and interception quality of the elastic wave-shaped filter 4 can be restored, and the interception efficiency and interception quality of the elastic wave-shaped filter 4 can be greatly reduced next time.

[0056] A rolling device is provided between the sphere 12 and the telescopic end of the telescopic member 11;

[0057] The rolling-through device is used to allow the ball 12 to roll through the position between the crests and troughs of the elastic wavy filter screen 4 when the ball 12 passes through the position between the crests and troughs of the elastic wavy filter screen 4, so as to reduce the friction between the ball 12 and the elastic wavy filter screen 4, thereby reducing the damage caused by the ball 12 to the elastic wavy filter screen 4, thereby extending the service life of the elastic wavy filter screen 4 while cleaning the large particles and / or strips on the elastic wavy filter screen 4.

[0058] The rolling-through device includes a connecting block 13 , which is disposed between the sphere 12 and the telescopic end of the telescopic member 11 . The sphere 12 is universally connected to the connecting block 13 .

[0059] The rotation driving member includes a first rotation motor 14 . The fixed end of the first rotation motor 14 is arranged at the middle position of the bottom end surface of the bracket 7 . The rotating end of the first rotation motor 14 is transmission-connected to the rotating disk 8 .

[0061] The bottom end surface of the shell 1 is open and not sealed, and the bottom end surface of the shell 1 is detachably provided with an opening and closing plate 17;

[0062] When the cleaning device and the fan 6 are not working and there are large particles and / or strips on the elastic wavy filter 4 on the opening and closing plate 17, the opening and closing plate 17 is operated to separate from the shell 1 to remove the large particles and / or strips on the opening and closing plate 17 from the shell 1, thereby preventing the air from driving the large particles and / or strips on the opening and closing plate 17 to flow toward the elastic wavy filter 4 when the fan 6 drives the air outside the shell 1 to enter the shell 1 through the several air inlets 2 next time, thereby reducing the interception efficiency and interception quality of the elastic wavy filter 4 for the large particles and / or strips in the air entering the shell 1 through the several air inlets 2.

[0063] A PM2.5 sensor (not shown), a virus sensor (not shown), a bacteria sensor (not shown), a formaldehyde sensor (not shown), a temperature sensor (not shown), and a humidity sensor (not shown) are provided on the inner wall of the shell 1 and below the elastic wavy filter 4.

[0066] During the period when the sphere 12 periodically rotates around the rotating disk 8 for several circles, the abutment plate 18 does not contact the elastic wave-shaped filter screen 4, so as to prevent the abutment plate 18 from causing wear to the elastic wave-shaped filter screen 4 during the period when the sphere 12 periodically rotates around the rotating disk 8 for several circles;

[0067] After the sphere 12 periodically revolves around the rotating disk 8 for several circles, the retractable end of the retractable member 11 is shortened to its shortest, the upper and lower driving members drive one end of the movable column 9 to periodically rotate up and down, and the rotating driving member drives the rotating disk 8 to periodically rotate by a predetermined angle until it completes one circle, so that the abutment plate 18 revolves around the rotating disk 8 once and periodically abuts against several wave crests of the elastic wave-shaped filter screen 4 during the period when the abutment plate 18 revolves around the rotating disk 8 once, thereby allowing large particles and / or strips at several wave crests and several wave troughs of the elastic wave-shaped filter screen 4 to quickly escape;

[0068] When the fan 6 is not working and the large particles and / or strips on the elastic wave-shaped filter 4 are cleaned circle by circle from the outside to the inside, the large particles and / or strips in the middle of the elastic wave-shaped filter 4 can be cleaned in a concentrated manner. During the concentrated cleaning, the large particles and / or strips at several peaks and several troughs of the elastic wave-shaped filter 4 can be quickly separated at the same time;
