[0002] An air purifier is a device that improves indoor air quality. Through various technologies such as filtration and adsorption, it effectively removes visible pollutants from the air, providing people with fresh and healthy air. This helps alleviate allergy symptoms, prevent respiratory diseases, and protect human health, playing a particularly important role in places with severe air pollution or special needs.

[0003] The surface of air purifier filters easily attracts pet hair and dust. Pet hair can clog the air intake holes on the filter surface, reducing the air purifier's filtration capacity. Users need to clean the hair on the filter surface frequently or replace the filter, which means the user experience needs improvement. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an air purifier that can improve the user experience.

[0006] An air purifier, comprising:

[0007] A columnar hollow filter element, along its axial direction, the columnar hollow filter element includes a first end and a second end opposite to each other;

[0008] A fan, located at the first end, is used to draw outside air from the side wall of the columnar hollow filter element into the hollow cavity of the columnar hollow filter element.

[0009] An impurity scraping component moves relative to the columnar hollow filter element to scrape off impurities adhering to the sidewall of the columnar hollow filter element.

[0010] An impurity container is fixed in position relative to the impurity scraper and moves relative to the columnar hollow filter. The impurity container has a receiving cavity. An impurity inlet is provided on the side of the impurity container opposite to the direction of movement of the columnar hollow filter.

[0037] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0038] Reference Figures 1 to 5 An air purifier includes a columnar hollow filter element 1, a fan 2, an impurity scraping element 3, and an impurity containing element 4. Along the axial direction of the columnar hollow filter element 1, the columnar hollow filter element 1 includes a first end 11 and a second end 12 opposite to each other.

[0039] The fan 2 is located on the first end 11 and is used to draw outside air from the side wall of the columnar hollow filter element 1 into the hollow cavity of the columnar hollow filter element 1.

[0040] The impurity scraping component 3 moves relative to the columnar hollow filter component 1 to scrape off the impurities attached to the side wall of the columnar hollow filter component 1.

[0041] The impurity container 4 is fixed in position relative to the impurity scraper 3 and moves relative to the columnar hollow filter 1. The impurity container 4 is provided with a receiving cavity 41. On the side of the impurity container 4 opposite to the direction of movement of the columnar hollow filter 1, there is an impurity inlet 42. The impurities scraped by the impurity scraper 3 are accumulated and contained in the receiving cavity 41.

[0042] The working principle of this embodiment is as follows: When the fan 2 is started, external air is drawn from the side wall of the columnar hollow filter element 1 into the hollow cavity of the columnar hollow filter element 1. After the air flows in through the columnar hollow filter element 1, it is filtered and purified, and clean air is discharged. Impurities attached to the air accumulate on the surface of the columnar hollow filter element 1. When the amount of impurities accumulated on the surface of the columnar hollow filter element 1 reaches a certain amount, the columnar hollow filter element 1 moves relative to the impurity scraping component 3. The impurity scraping component 3 scrapes the impurities on the surface of the columnar hollow filter element 1 into the receiving cavity 41 of the impurity receiving component 4. The impurity receiving component 4 can temporarily store impurities to improve the filtration quality of the air purifier and reduce the frequency of filter element replacement.

[0043] Specifically, the air purifier in this embodiment can be used to filter pet hair. When pet hair easily clogs the air inlet holes on the filter surface, reducing the filtration capacity of the air purifier, the air purifier in this embodiment can solve the technical problem that users need to frequently clean the pet hair on the filter surface.

[0044] Specifically, in this embodiment, the columnar hollow filter element 1 moves in two ways relative to the impurity scraping element 3 and the impurity containing element 4: the first is that the columnar hollow filter element 1 remains stationary while the impurity scraping element 3 and the impurity containing element 4 move around the periphery of the columnar hollow filter element 1; the second is that the columnar hollow filter element 1 rotates on its own axis while the impurity scraping element 3 and the impurity containing element 4 remain stationary.

[0045] Specifically, the columnar hollow filter element 1 is a hollow cylinder.

[0046] More specifically, in order to optimize the filtration effect and improve the filtration quality, the outer diameter of the fan 2 is equal to the diameter of the first end 11. That is, the air blown in the fan 2 is completely filtered by the columnar hollow filter element 1 after flowing in through the side wall of the columnar hollow filter element 1, so as to improve the filtration quality of the air and reduce the impurity content in the filtered air.

[0047] In one embodiment, the second end 12 is in a closed state and has no communication with the outside world, that is, the columnar hollow filter element has only one open opening, located at the first end 11.

[0048] In one embodiment, the air purifier further includes a housing 5, which has a plurality of air inlets 51. The fan 2 and the columnar hollow filter element 1 are disposed in the housing 5, and the impurity scraping element 3 and the impurity containing element 4 are both fixed to the inner wall of the housing 5.

[0049] The outer casing 5 serves as a connecting structure to fix the relative positions of the fan 2, the columnar hollow filter element 1, the impurity scraper 3, and the impurity container 4, preventing changes in the positional relationship between the components. In this embodiment, the outer casing 5 rotates, causing the impurity scraper 3 and the impurity container 4 to scrape the impurities on the surface of the columnar hollow filter element 1; or the columnar hollow filter element 1 rotates, causing the impurity scraper 3 and the impurity container 4 to scrape the impurities attached to its surface.

[0050] Specifically, the air inlets 51 are evenly distributed on the outer shell 5, and air enters the cavity of the columnar hollow filter 1 evenly along the periphery of the filter element 1. Impurities are evenly attached to the outside of the columnar hollow filter 1, thus avoiding insufficient cleaning in some areas when cleaning the columnar hollow filter 1.

[0051] In one embodiment, the air purifier further includes a drive member 6 that is tractively connected to the second end 12, the drive member 6 being used to drive the columnar hollow filter 1 to rotate relative to the impurity scraper 3 and the impurity container 4.

[0052] It is understood that the rotation rate of the columnar hollow filter element 1 relative to the impurity scraping element 3 is equal to the rotation rate of the columnar hollow filter element 1 relative to the impurity containing element 4.

[0053] Specifically, the output end of the driving component 6 is connected to the axis of the columnar hollow filter 1, driving the columnar hollow filter 1 to rotate on its own axis.

[0054] Reference Figure 4 In one embodiment, the impurity scraping member 3 is provided with a wiping member 7 that has deformation capability. The wiping member 7 has at least one contact line with the surface of the columnar hollow filter member 1, and the contact line is parallel to the axis of the columnar hollow filter member.

[0055] In this embodiment, the contact method and contact direction between the wiping member 7 and the surface of the columnar hollow filter 1 are defined to ensure that after the wiping member 7 scrapes off the impurities, the impurities can enter the receiving cavity 41 through the impurity inlet 42 as the columnar hollow filter 1 rotates.

[0056] It is understandable that when the wiping member 7 contacts the surface of the columnar hollow filter 1 in a surface contact manner, it means that there are several contact lines between the wiping member 7 and the surface of the columnar hollow filter 1.

[0057] Specifically, the wiping element 7 is a brush.

[0058] In one embodiment, the impurity scraping member 3 and the impurity receiving member 4 are fixedly connected, and both the impurity scraping member 3 and the impurity receiving member 4 are detachably connected to the outer shell 5.

[0059] When the impurity container 4 contains a sufficient amount of impurities, the space of the container cavity 41 is filled. The impurity container 4 is then removed from the outer shell 5, the container cavity 41 is cleaned, and the impurity container 4 is then reinstalled onto the outer shell 5.

[0060] Reference Figure 4 and Figure 5 In one embodiment, the impurity scraping member 3 and the impurity receiving member 4 are integrally formed. The impurity receiving member 4 is then removed.

[0061] In one embodiment, the outer shell 5 is provided with a slot 52, which is parallel to the axis of the columnar hollow filter element 1, and the impurity scraping element 3 and the impurity receiving element 4 are engaged with the slot 52.

[0062] Because the impurity scraper 3 and the impurity container 4 are designed as a single unit, the impurity scraper 3 can be pulled out of the slot 52 along the length of the slot 52.

[0063] Reference Figure 4 In one embodiment, the radial section of the columnar hollow filter element 1 is defined as the first surface;

[0064] On the first surface, the slot 52 is composed of two L-shaped blocks 521 fixed inside the outer shell 5. The two L-shaped blocks are arranged opposite to each other to form the slot 52. The slot width of the slot 52 is d. The impurity scraping component 3 includes a first limiting block 31 for being inserted into the slot 52, a first fixing block 32 located outside the slot 52, and a connecting block 33 connecting the first limiting block 31 and the first fixing block 32. The width of the connecting block 33 is less than or equal to d, and the widths of the first limiting block 31 and the first fixing block 32 are greater than d.

[0065] In one embodiment, along the axial direction of the columnar hollow filter element 1, the impurity container 4 is provided with a rear end cover 43, which is used to limit the overflow of impurities in the container cavity 41.

[0066] In one embodiment, along the axial direction of the columnar hollow filter element 1, the lengths of the impurity scraping element 3 and the impurity receiving element 4 are both longer than or equal to the length of the columnar hollow filter element 1, so as to cover the length of the columnar hollow filter element 1 and ensure that the impurity scraping element 3 can fully contact the columnar hollow filter element 1.

[0067] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
