The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.
As shown in fig. 1 to 7, an embodiment of the present application provides an air cleaner, which includes a housing 1, a bracket 3, a rotating member 4, a transmission shaft 5, and at least two filter plates 2, wherein the housing 1 has an air inlet 11 and an air outlet 12, the filter plates 2 are arranged in the housing 1 along the direction from the air inlet 11 to the air outlet 12, the filter plates 2 have through holes 21, the central axes of the through holes 21 are perpendicular to the surfaces of the filter plates 2, the bracket 3 is arranged in the housing 1, the rotating member 4 is rotatably arranged on the bracket 3, the transmission shaft 5 is connected with the rotating member 4 and can rotate therewith, and the transmission shaft 5 is rotatably arranged in the through holes 21 of the filter plates 2; wherein, all be equipped with scraper blade 6 between two arbitrary adjacent filter 2, scraper blade 6 is connected and can rotate along with transmission shaft 5, and scraper blade 6 extends along the radial of transmission shaft 5, and scraper blade 6 is close to the surface setting of filter 2.
Based on the structure, the rotating piece 4 drives the scraping plate 6 to rotate, so that the scraping plate 6 scrapes off dust accumulated on the surface of the filter plate 2, thereby realizing an automatic dust removing function, eliminating the need of manually cleaning the air filter frequently, reducing the cleaning and maintenance time and prolonging the service period; in addition, the scraping plate 6 can clean the air filter in real time and continuously, so that the ventilation and filtering effects of the air filter are guaranteed, and the efficiency of the engine is further improved. Secondly, the structure that filter 2 and scraper blade 6 alternate set up is compacter for this air cleaner's volume is less, and occupation space is less.
Alternatively, in the present embodiment, considering that when the scraper 6 scrapes off dust on the surface of the filter plate 2, part of the dust remains on the filter plate 2, particularly may remain in the filter holes, as shown in fig. 4 and 5, the two side surfaces of the scraper 6 each have a spring piece 61, the spring pieces 61 are disposed near the surface of the filter plate 2, the filter plate 2 has a protrusion 22 corresponding to the spring pieces 61, the spring pieces 61 can reach a compressed state and a released state along with rotation of the scraper 6, and when the spring pieces 61 are in the compressed state, the protrusion 22 abuts against the spring pieces 61 and compresses the spring pieces 61; when the elastic piece 61 is in the released state, the elastic piece 61 and the boss 22 are staggered from each other. Based on this, when shell fragment 61 changes from compressing tightly the state to release the state, shell fragment 61 takes place to kick-back to clap filter 2, thereby make the dust in filter 2 especially the filtration pore drop, thereby further optimized the dust removal effect, guaranteed the ventilation of this air cleaner.
Alternatively, as shown in fig. 4 and 5, in the present embodiment, the elastic sheet 61 includes a fixing section 611, a main body section 612 and a wing section 613, the fixing section 611 is connected with the scraper 6, the main body section 612 is connected with the fixing section 611, the main body section 612 is inclined in a direction away from the surface of the scraper 6, the wing sections 613 are two and respectively provided on two sides of the main body section 612, and the wing section 613 is inclined towards the surface of the scraper 6 and forms an abutment inclined plane, and the abutment inclined plane is used for abutting against the protruding portion 22. It will be appreciated that the body section 612 is provided adjacent to the surface of the filter plate 2, which upon rebound can flap the filter plate 2. In this way, in the process of converting the elastic sheet 61 from the release state to the compression state, the protruding portion 22 is firstly abutted against the abutting inclined surface and then is gradually abutted against the main body section 612, so that the relative movement of the protruding portion 22 and the main body portion is gentle, the power loss of the rotating member 4 in the contact process of the main body portion and the protruding portion 22 is small, that is, the rotating member 4 and the scraping plate 6 rotate more smoothly, the damage of the elastic sheet 61 or the filter plate 2 caused by the rigid collision between the main body portion and the protruding portion 22 can be prevented, and the functions of protecting the elastic sheet 61 and the filter plate 2 are achieved.
Alternatively, in the present embodiment, considering that the volume and size of the blade 6 affect the ventilation amount of the air cleaner, too large a size of the blade 6 may obstruct the air intake of the air cleaner, and too small a size of the blade 6 makes it difficult to provide the elastic piece 61, so that it is necessary to reasonably set the structure of the blade 6. As shown in fig. 5, the scraper 6 includes a first plate portion 62 and a second plate portion 63, wherein a first end of the first plate portion 62 is connected to the transmission shaft 5, two second plate portions 63 are provided, the two second plate portions 63 are respectively erected on two side surfaces of the first plate portion 62, and the second plate portions 63 are closely attached to the surface of the filter plate 2; the longitudinal cross-sectional area of the first plate portion 62 along the axial direction of the transmission shaft 5 gradually decreases from the second end of the first plate portion 62 to the first end thereof, the elastic piece 61 is disposed on the first plate portion 62, the elastic piece 61 is disposed near the second end of the first plate portion 62, and the second plate portion 63 is disposed between the elastic piece 61 and the transmission shaft 5. Based on this, the elastic sheet 61 is disposed at the wider second end of the second plate 63, and the first plate 62 is disposed on the second plate 63, so that the occupied area of the first plate is smaller, and the width of the second plate 63 gradually decreases from the second end to the first end, which is beneficial to reducing the influence on the ventilation.
Alternatively, as shown in fig. 1, in this embodiment, the end of the scraper 6 away from the transmission shaft 5 has a scraping head 64, the scraping head 64 protrudes from the outer circumferential wall of the filter plate 2, the inner circumferential wall of the housing 1 has an annular collecting groove 13 corresponding to the scraping head 64, the scraping head 64 extends into the collecting groove 13, and the scraping head 64 slides in the collecting groove 13 when rotating with the scraper 6. On this basis, the dust scraped off by the scraper 6 can be collected in the collecting tank 13 to prevent the dust from flying in the housing 1, and the scraper head 64 can slide in the collecting tank 13 to clean the dust collected in the collecting tank 13, thereby optimizing the effect of collecting the dust after dust removal.
Optionally, as shown in fig. 1, in this embodiment, the device further includes a collecting box 14 disposed on the housing 1, where the collecting box 14 protrudes from the outer peripheral wall of the housing 1 along the radial direction of the transmission shaft 5, and the collecting box 14 is in communication with the collecting tank 13. In this way, the scraping head 64 can continuously scrape dust in the collecting tank 13 into the collecting box 14, thereby further optimizing the dust collecting effect. Preferably, the collecting box 14 is detachably connected with the shell 1, so that the collecting box 14 can be conveniently dismounted and mounted, dust in the collecting box can be cleaned, the shell 1 does not need to be integrally dismounted, and the dust can be cleaned conveniently.
Alternatively, as shown in fig. 4, in the present embodiment, considering that dust easily flies onto the filter plate 2 when the scraper head 64 scrapes dust in the collecting tank 13, one end of the scraper head 64 to which the scraper blade 6 is attached has a baffle 641, and the baffles 641 are provided in two and provided on both sides of the scraper head 64 facing the filter plate 2, respectively. Based on this, the shutter 641 functions to block dust, preventing dust from flying onto the filter plate 2 when the scraping head 64 scrapes dust in the collecting tank 13.
Alternatively, as shown in fig. 4, in the present embodiment, the baffle 641 abuts against the outer peripheral wall of the filter plate 2. Thus, when the scraper head 64 rotates, the shutter 641 can further scrape dust on the outer peripheral wall of the filter plate 2.
Alternatively, as shown in fig. 7, in the present embodiment, the outer wall of the housing 1 has a mounting block 15, and the mounting block 15 has a first connection hole 151 extending in the axial direction of the drive shaft 5.

The impeller 41 is arranged in a manner that the air filter is of a pure mechanical structure, and the reliability and the safety are high. Of course, the rotating member 4 is not limited to the arrangement form of the impeller 41, and may be any other arrangement form such as a motor, so long as the rotating member 4 can drive the scraper 6 to rotate, and when the rotating member 4 is in any other arrangement form, the bracket 3 may be disposed at any other position in the housing 1, and is not limited to the space between the air inlet 11 and the filter plate 2, so long as the function of supporting the rotating member 4 can be achieved.

Based on this, compared with the arrangement mode that the single impeller 41 directly drives the transmission shaft 5 to rotate, the plurality of impellers 41 can rotate in the same direction by utilizing the air inlet in all directions, so that the second gear 43 and the first gear 42 can drive the scraper 6 to rotate better, and the scraper 6 can rotate more smoothly. Of course, it is also possible to provide that a single impeller 41 is connected to the drive shaft 5 for rotating the scraper 6.
