However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] See also Figure 1 and Figure 2 An air filter 100 provided in one embodiment of the present invention includes a housing 10 , a housing cover 11 disposed on the top of the housing 10 , and an air filter element 12 disposed in the housing 10 .

[0028] See also Figure 2 and Figure 3 The air filter element 12 includes a containing box 121, in which a containing cavity is provided which runs through both ends of the containing box 121, and the containing cavity is filled with a plurality of filter material modules 122 made of plant fibers, and adjacent filter material modules 122 are separated by partitions 123, and both ends of the containing box 121 are provided with external nets 124.

[0029] It should be noted that in this embodiment, a plurality of filter material modules 122 are used. On the one hand, it is not necessary to design a special mold according to the shape of the containing box 121, which is convenient for the processing of the filter material module 122; on the other hand, the volume of the filter material module 122 is small, and the force of the internal plant fiber is relatively small, so that the structure of the filter material module 122 takes longer to be finalized. The filter material module 122 includes coarse fiber, medium fiber and fine fiber. After multiple tests and verifications by the applicant, the particle diameter range of the coarse fiber is 0.4-0.5 mm, the particle diameter range of the fiber is 0.25-0.35 mm, and the particle diameter range of the fine fiber is 0.15-0.25 mm. The role of the coarse fiber is to serve as a gradient support material for supporting the medium fiber and the fine fiber; the role of the medium fiber is to serve as a gradient support material for the fine fiber; the role of the fine fiber is to serve as the main filling material and to form a tiny air filtration channel.

[0030] Specifically, in this embodiment, the coarse fiber is made of rattan or melon vine, because this type of fiber is rich in wax, light in texture, good in toughness, multi-porous and has adsorption properties, thereby preserving the aroma of the fragrant medium fiber for a long time; the medium fiber is made of camphor wood or gardenia, because this type of fiber contains natural fragrance and has antibacterial, refreshing and other health care effects; the fine fiber is made of bamboo, because this type of fiber has a fine fiber diameter, good fluidity, and excellent water absorption, and has natural anti-mildew and antibacterial effects.

[0031] It can be understood that in other inventions, the coarse fiber can be jute, coix straw or peanut shell in addition to rattan or melon vine; the medium fiber can be camphor wood or gardenia, or one or more of sandalwood, nanmu, agarwood, pine, rosewood, cypress, rose, jasmine, osmanthus or lavender; the fine fiber can be coconut shell in addition to bamboo.

[0032] See also Figure 4 In order to match the inner cavity structure of the housing 10, the cross-sectional shape of the housing box 121 is a trapezoid. It can be understood that in other embodiments, the cross-sectional shape of the housing box 121 can be a rectangle, a triangle or a circle in addition to a trapezoid, depending on the inner cavity structure of the housing 10.

[0033] See also Figure 5 The partition 123 includes a horizontal plate 1231 and a vertical plate 1232, and the horizontal plate 1231 and the vertical plate 1232 form a "cross" structure. The partition 123 is used to separate the filter material modules 122 to avoid the force between the plant fibers of the adjacent filter material modules 122, thereby shortening the structural shaping time of the filter material modules 122.

[0034] Specifically, in this embodiment, the partition 123 is made of camphor wood, which can not only separate the filter material module 122, but also further enhance the fragrance of the air filter element 12 due to its natural fragrance. It can be understood that in other embodiments, the partition 123 can be made of sandalwood, nanmu, agarwood, pine, rosewood or cypress in addition to camphor wood.

[0035] It should be noted that, in this embodiment, in order to weld the outer net 124 to the outer wall of the containing box 121, the edge of the outer net 124 extends outwardly at the end of the containing box 121 to overlap, and the length of the overlap is not less than 5 cm. In order to prevent the particles of the plant fiber from passing through the outer net 124, the mesh number of the outer net 124 is less than 150 meshes.

[0036] See also Figure 1 and Figure 2 The shell 10 is provided with a receiving cavity for receiving the receiving box 121, and the shape of the receiving cavity is the same as the shape of the receiving box 121. The bottom of the shell 10 and the top of the shell cover 11 are respectively provided with evenly distributed air holes, and the function of the air holes is to facilitate the passage of air and enter the air filter element 12 for filtration.

[0037] Furthermore, a mounting portion 101 with a "T"-shaped cross-section is formed on the outer wall of the shell 10, and the mounting portion 101 includes a connecting portion 1011 connected to the outer wall of the shell 10, and a "T"-shaped end 1012 vertically connected to the connecting portion 1011, and a snap-fit ​​strip 1013 is vertically provided on the connecting portion 1011, and the snap-fit ​​strip 1013 is located on one side of the shell 10. The function of the mounting portion 101 and the snap-fit ​​strip 1013 is to facilitate the installation of the air filter 100.

[0038] In summary, in the air filter element 12 of the present invention, since the filter material module 122 is made of plant fiber, the cost is low, and since it does not contain any additives, it has no side effects on the human body during use.

[0039] The above-mentioned embodiments only express certain implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
