Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0036] like Figure 1-11 As shown, the present application provides an air purification device, including a placement seat 1, a purification seat 2 is installed on the upper end surface of the placement seat 1, a purification chamber 201 is opened inside the purification seat 2, a plurality of filter cartridges 3 are installed on the cavity wall of the purification chamber 201, a plurality of the filter cartridges 3 are arranged in a circular array inside the purification chamber 201, a filter net is arranged on the outer surface of each of the filter cartridges 3, a purification liquid seat 4 is installed inside the purification chamber 201 and close to one side of the plurality of the filter cartridges 3, a disinfectant is filled inside the purification liquid seat 4, a cleaning mechanism is arranged inside the purification chamber 201, and the cleaning mechanism is used to clean impurities adhered to the outer wall of the filter cartridge 3;

[0037] During operation, when the air purification device in the present invention is used, the placement seat 1 is placed in an air circulation place. During the circulation of external air, it will enter the purification chamber 201 inside the purification seat 2, and under the preliminary filtration of multiple filter cartridges 3, impurities in the air can be preliminarily filtered, and the impurities will be blocked on the surface of the filter cartridge 3. Then, the disinfectant inside the purification liquid seat 4 can remove harmful substances in the air; subsequently, through the action of the cleaning mechanism, impurities and dust adhered to the outer wall of the filter cartridge 3 can be cleaned, and the filter cartridge 3 is preliminarily cleaned, thereby increasing the use time of each filter cartridge 3 and facilitating the subsequent continued purification of the air.

[0038] The cleaning mechanism includes a circular support plate 5 slidably arranged at the bottom of the purification seat 2, and a plurality of support columns 501 are installed on the upper end surface of the circular support plate 5. The top ends of the plurality of support columns 501 are arranged in a one-to-one correspondence with the bottom ends of the plurality of filter cartridges 3, and the top ends of each of the support columns 501 and the bottom ends of each of the filter cartridges 3 are connected through a connecting unit; a plurality of elastic frames 6 are installed on the bottom wall of the purification seat 2, a contact 1 7 is installed at the bottom end of the circular support plate 5, and a contact 2 8 is installed at a position corresponding to the contact 1 7 at the bottom of the purification seat 2, and a plurality of cleaning rings 9 are arranged on the surface of the purification seat 2, and the cleaning rings 9 are located above the filter cartridges 3, and each of the cleaning rings 9 and each of the filter cartridges 3 are arranged in a one-to-one correspondence;

[0039] During operation, when the filter cartridge 3 and the purification liquid holder 4 purify the air normally, the circular support plate 5 does not change, and the contact 1 7 and the contact 2 8 do not contact each other; as the air impurities adhered to the surface of the filter cartridge 3 increase, the weight of all the filter cartridges 3 will gradually increase. When the weight of all the filter cartridges 3 is greater than the supporting force of the elastic frame 6 at the bottom of the circular support plate 5, all the filter cartridges 3 will drive the circular support plate 5 to move downward, so that the circular support plate 5 drives the contact 1 7 to move toward the side close to the contact 2 8, and then the contact 1 7 and the contact 2 8 will contact each other. At this time, the external circuit is connected, so that the external controller will control all the cleaning rings 9 to move downward, so that the inner wall of the cleaning ring 9 automatically cleans the impurities adhered to the outside of the filter cartridge 3, so as to avoid excessive impurities adhering to the outer wall of the filter cartridge 3, which affects its normal air filtering function, and the operation is more convenient.

[0040] The cleaning mechanism also includes an electric telescopic rod 10 fixedly mounted on the inner wall of the purification seat 2, a sliding ring 11 is fixedly mounted on the telescopic end of the electric telescopic rod 10, and a plurality of fixed support rods 12 are mounted on the upper end surface of the sliding ring 11, and each of the fixed support rods 12 is connected to the side wall of the cleaning ring 9 on a side away from the sliding ring 11;

[0041] During operation, when contact 1 7 and contact 2 8 are in contact and the external circuit is turned on, the external controller will control the telescopic end of the electric telescopic rod 10 to move downward, so that the electric telescopic rod 10 drives the sliding ring 11 and all the fixed support rods 12 to move downward, and the fixed support rods 12 drive the cleaning ring 9 to move downward, so that the cleaning ring 9 cleans the adhered impurities on the outer surface of the filter cartridge 3 from top to bottom, and the operation is more convenient.

[0042] The inner wall of each cleaning ring 9 is sleeved with a cleaning brush, and the surface of each cleaning ring 9 is provided with an adsorption hole 13, and the adsorption hole 13 is arranged corresponding to the external suction pipe;

[0043] During operation, when the cleaning ring 9 moves from top to bottom, the cleaning brush on the inner wall of the cleaning ring 9 removes impurities on the outer surface of the filter cartridge 3, and the impurities remain on the cleaning brush surface of the inner wall of the cleaning ring 9. When the cleaning ring 9 moves to the bottom of the filter cartridge 3, the adsorption holes 13 on the outer wall of the cleaning ring 9 just correspond to the external suction pipe. Figure 8 As shown, the impurities in the cleaning ring 9 can be removed by suction through the external suction pipe, thereby facilitating the subsequent use of the cleaning ring 9.

[0044] After one cleaning is completed, the electric telescopic rod 10 is controlled to move up again to restore all the cleaning rings 9 to their initial positions.

[0045] A rotating shaft 14 is rotatably arranged inside the purification liquid seat 4, and a plurality of stirring blades 141 are fixedly installed on the outer circumference of the rotating shaft 14. A spiral groove 15 is provided on the outer circumference of the rotating shaft 14. A linkage support rod 16 is installed on the inner wall of the sliding ring 11. The side of the linkage support rod 16 away from the sliding ring 11 is arranged inside the spiral groove 15.

[0046] During operation, when the sliding ring 11 moves downward following the electric telescopic rod 10, the sliding ring 11 will simultaneously drive the linkage support rod 16 of the side wall to move downward. Since the end of the linkage support rod 16 is arranged inside the spiral groove 15, the rotating shaft 14 can rotate at a certain angle under the mutual limitation of the linkage support rod 16 and the spiral groove 15, so that the rotating shaft 14 drives the stirring blade 141 to rotate. When the stirring blade 141 stirs the disinfectant inside the purification liquid seat 4, the combination effect of the internal disinfectant and harmful substances in the air is improved.

[0047] The length of the spiral groove 15 is matched with the moving distance of the sliding ring 11; a sphere is arranged at the contact position between the end of the linkage support rod 16 and the spiral groove 15, and a circular groove matched with the rotating shaft 14 is opened inside the purification liquid seat 4; when working, the circular groove is arranged to facilitate the rotation of the rotating shaft 14 inside the purification liquid seat 4, and the sphere is arranged at the end of the linkage support rod 16, which can facilitate the mutual engagement with the spiral groove 15, so that the rotating shaft 14 rotates at a certain angle.

[0048] The connecting unit includes an annular groove 17 formed on the bottom wall of each filter cartridge 3, and the groove wall of the annular groove 17 is formed with two arc-shaped grooves 171. The top of the support column 501 is installed inside the arc-shaped groove 171 through a rubber arc block 18; the shape of the rubber arc block 18 and the arc-shaped groove 171 are adapted to each other;

[0049] During operation, when the filter cartridge 3 is in normal use, the rubber arc block 18 will be located inside the arc groove 171. Under the mutual limitation of the rubber arc block 18 and the arc groove 171, the stability of the filter cartridge 3 during use can be ensured, ensuring that it can purify the air normally.

[0050] The upper end surface of the purification seat 2 is installed with an electric telescopic rod 2 19, the telescopic end of the electric telescopic rod 2 19 is installed with a sliding ring 20, and the upper end surface of the sliding ring 20 is installed with a plurality of brackets 21, and the end of the bracket 21 away from the sliding ring 20 is connected to the upper end surface of the filter cartridge 3;

[0051] During operation, when the filter cartridge 3 needs to be replaced after long-term use, the telescopic end of the electric telescopic rod 19 is controlled to move upward, and the telescopic end of the electric telescopic rod 19 drives the sliding ring 20 to move upward, and the sliding ring 20 drives multiple brackets 21 to move upward, and the bracket 21 drives the filter cartridge 3 away from the support column 501, so that the rubber arc block 18 on the surface of the support column 501 is pushed out from the inside of the arc-shaped groove 171, and then the filter cartridge 3 can be replaced, and the operation is relatively convenient.

[0052] A spring is arranged inside the rubber arc block 18, and a rounded corner is arranged on the surface of the arc-shaped slot 171. The end of the bracket 21 is clamped with the upper end surface of the filter cartridge 3. During operation, since a spring is arranged inside the rubber arc block 18 and a rounded corner is arranged on the surface of the arc-shaped slot 171, the rubber arc block 18 can be conveniently clamped inside the arc-shaped slot 171, and the rubber arc block 18 can be conveniently taken out from the arc-shaped slot 171, and the filter cartridge 3 can be replaced. After one replacement is completed, the new filter cartridge 3 can be placed inside the purification seat 2.

[0053] A guide frame adapted to the bracket 21 is disposed inside the purification seat 2. The arrangement of the guide frame facilitates the bracket 21 to move up and down.

[0054] Working principle: When the air purification device in the present invention is used, the placement seat 1 is placed in an air circulation place. During the circulation of external air, it will enter the purification chamber 201 inside the purification seat 2, and under the preliminary filtration of multiple filter cartridges 3, impurities in the air can be initially filtered, and the impurities will be blocked on the surface of the filter cartridge 3. Then, the disinfectant inside the purification liquid seat 4 can remove harmful substances in the air; then, through the action of the cleaning mechanism, the impurities and dust adhered to the outer wall of the filter cartridge 3 can be cleaned, and the filter cartridge 3 is preliminarily cleaned, thereby increasing the use time of each filter cartridge 3 and facilitating the subsequent continued purification of the air; when the filter cartridge 3 and the purification liquid seat 4 purify the air normally , at this time, the circular support plate 5 has not changed, and the contact 1 7 and the contact 2 8 are not in contact; as the air impurities adhered to the surface of the filter cartridge 3 increase, the weight of all the filter cartridges 3 will gradually increase. When the weight of all the filter cartridges 3 is greater than the supporting force of the elastic frame 6 at the bottom of the circular support plate 5, all the filter cartridges 3 will drive the circular support plate 5 to move downward, so that the circular support plate 5 drives the contact 1 7 to move to the side close to the contact 2 8, and then the contact 1 7 and the contact 2 8 will contact. At this time, the external circuit is connected, so that the external controller will control all the cleaning rings 9 to move downward, so that the inner wall of the cleaning ring 9 automatically cleans the impurities adhered to the outside of the filter cartridge 3, so as to avoid excessive impurities adhering to the outer wall of the filter cartridge 3, affecting its normal air filtering function, and the operation is more convenient;

[0055] When the contact 1 7 and the contact 2 8 are in contact, and the external circuit is turned on, the external controller will control the telescopic end of the electric telescopic rod 10 to move downward, so that the electric telescopic rod 10 drives the sliding ring 11 and all the fixed support rods 12 to move downward, and the fixed support rod 12 drives the cleaning ring 9 to move downward, so that the cleaning ring 9 cleans the adhered impurities on the outer surface of the filter cartridge 3 from top to bottom, and the operation is more convenient; when the cleaning ring 9 moves from top to bottom, the cleaning brush on the inner wall of the cleaning ring 9 removes the impurities on the outer surface of the filter cartridge 3, and the impurities remain on the cleaning brush surface of the inner wall of the cleaning ring 9. When the cleaning ring 9 moves to the bottom of the filter cartridge 3, the adsorption hole 13 on the outer wall of the cleaning ring 9 just corresponds to the external suction pipe. Figure 8 As shown, the impurities in the cleaning ring 9 can be removed by suction through the external suction pipe, thereby facilitating the subsequent use of the cleaning ring 9;

[0056] When the sliding ring 11 moves downward with the electric telescopic rod 10, the sliding ring 11 will simultaneously drive the linkage support rod 16 of the side wall to move downward. Since the end of the linkage support rod 16 is arranged inside the spiral groove 15, the rotating shaft 14 can rotate at a certain angle under the mutual limitation of the linkage support rod 16 and the spiral groove 15, so that the rotating shaft 14 drives the stirring blade 141 to rotate. Under the stirring of the disinfectant inside the purification liquid seat 4 by the stirring blade 141, the combination effect of the internal disinfectant and the harmful substances in the air is improved; when the filter cartridge 3 needs to be replaced after long-term use, at this time, by controlling the telescopic end of the electric telescopic rod 2 19 to move upward, the telescopic end of the electric telescopic rod 2 19 drives the sliding ring 20 to move upward, the sliding ring 20 drives multiple brackets 21 to move upward, and the bracket 21 drives the filter cartridge 3 away from the support column 501, so that the rubber arc block 18 on the surface of the support column 501 is pushed out from the arc-shaped groove 171, and then the filter cartridge 3 can be replaced, and the operation is relatively convenient.

[0057] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
