[0035] This embodiment is an air filter with air treatment function, referring to Figure 1-6 , which comprises a first filter element 11, a second filter element 12 and an air treatment plug-in 2 arranged between the first filter element 11 and the second filter element 12. The first filter element 11 and the second filter element 12 have the same structure, both comprising a wave-shaped folded filter paper 101 and a frame 102 at least partially surrounding the folded filter paper 101, the outer side of the folded filter paper 101 parallel to the folding line is called a folding side, the outer side of the folded filter paper 101 perpendicular to the folding line is called a vertical side, and the frame 102 surrounds the vertical side of the folded filter paper 101. The air treatment plug-in 2 is arranged parallel to the folding line direction of the folded filter paper 101, and a connecting portion 22 is provided on both sides of the air treatment plug-in 2. The first filter element 11 and the second filter element 12 are connected to each other through the connecting portions 22 on both sides of the air treatment plug-in 2. The air treatment plug-in has a receiving cavity 211 and a vent 24 connecting the receiving cavity 211 with the outside, and the receiving cavity 211 has a functional object for fresh air built in.

[0036] By arranging the air treatment plug-in 2 between the first filter element 11 and the second filter element 12, the air filter not only has the function of filtering dust or other impurities, but also has the function of emitting fragrance, deodorizing or sterilizing. Moreover, since the air treatment plug-in 2 connects the first filter element 11 and the second filter element 12 to form a filter element as a whole, the filter element as a whole can be installed in the filter element installation cavity of the original assembly, and there is no need to design a separate space for the aromatherapy as in the prior art. It can be installed without modifying the equipment, which optimizes the structure of the air filter and improves the application adaptability of the product. In this embodiment, the first filter element 11 and the second filter element 12 have the same thickness size. Of course, in other embodiments, they can also have different thickness sizes. In this way, the air treatment plug-in connects the first filter element 11 and the second filter element 12 of different thickness sizes to form a special-shaped filter element, which is suitable for air filters with different cavity requirements, further improving the application adaptability.

[0037] In this embodiment, refer to Figure 5The connecting portion 22 is a slot structure, the air treatment plug-in 2 includes a container 21 and a clamping block, the accommodating cavity 211 is arranged in the container 21, the clamping block is arranged outside the container 21, and a gap is left between the clamping block and the container 21 to form a slot structure, the outermost filter paper of the folded filter paper 101 of the first filter element 11 is clamped in the slot structure on one side of the air treatment plug-in 2, and the outermost filter paper of the folded filter paper 101 of the second filter element 12 is clamped in the slot structure on the other side of the air treatment plug-in 2, so that the air treatment plug-in 2 firmly connects the first filter element 11 and the second filter element 12 together. Preferably, the gap width of the slot structure is 0.5-1 mm, and the appropriate gap width helps the connecting portion 22 to better clamp and fix the filter paper of the air filter.

[0038] In this embodiment, the air treatment plug-in 2 further includes a cover 23, and the accommodating cavity 211 is provided with an opening, and the cover 23 is used to open or close the opening. Figure 6 , a strip-shaped slide groove 212 is formed at the opening of the container 21 for the cover 23 to slide, and an outlet for the cover 23 to slide out is formed at one end of the container 21. By sliding the cover 23 in the strip-shaped slide groove 212, the cover 23 can slide and open and close on the opening of the container 21. When the smell of the functional object in the accommodating cavity 211 becomes weak or ineffective, the functional object can be taken out and replaced by opening the cover 23, which is more economical and environmentally friendly. The other end of the strip-shaped slide groove 212 of the container 21 is closed, and a limit strip 213 is provided at the top of the strip-shaped slide groove 212. A groove 233 matching the limit strip 213 is provided at the top of the cover 23. After the cover 23 slides to cover the opening, the limit strip 213 is embedded in the groove 233, thereby limiting the cover 23 on the opening of the container 21. Of course, in other embodiments, the cover 23 can also be limited to the opening of the container 21 by relying on the friction force of the cover 23 on the container 21.

[0039] In this embodiment, the air treatment plug-in 2 has two parallel containers 21, each of which is provided with a accommodating cavity 211 and is respectively connected to a cover body 23. By providing two accommodating cavities 211, different types of functional objects can be placed on the air treatment plug-in 2, such as aromatherapy, deodorants, antibacterial agents, etc. The user can freely choose to place substances with different functions according to needs to achieve different effects, with a wide range of use and a high degree of freedom.

[0040] In this embodiment, the surface of the air treatment plug-in 2 is recessed in the surfaces of the first filter element 11 and the second filter element 12, or the surface of the air treatment plug-in 2 is flush with the surfaces of the first filter element 11 and the second filter element 12. In this way, when the filter element is installed in the cavity of the assembly, the installation will not be affected by the protrusion of the air treatment plug-in 2 from the surface of the filter element, thereby improving the versatility of the air treatment plug-in 2, and the filter element can also fit better in the cavity, which is beneficial to the filtering effect.

[0041] In this embodiment, there are multiple vents 24, and two vent design methods are given as examples: first, several vents 24 can be formed on the cover 23, and the vents 24 on the cover 23 can be used as air inlets and air outlets; second, at least one vent 24 is formed on the cover 23 as an air outlet, and at least one vent 24 is formed on the bottom of the container 21 as an air inlet. The vent 24 in this embodiment is the second design method: the shape of the vent 24 on the cover 23 can be a certain hollow pattern or LOGO, which can not only play a ventilation role, but also improve the overall aesthetics; the shape of the vent 24 at the bottom of the container 21 is circular, oval, square, triangular, etc. The aperture of all vents 24 used as air inlets or air outlets is smaller than the diameter of the functional object in the accommodating cavity 211 to prevent it from falling out. By setting multiple vents 24, it is convenient for gas to enter and exit the container 21, and the characteristics of the functional object in the accommodating cavity 211 are released into the air.

[0042] In this embodiment, a protrusion is extended from one end of the cover body 23. When the cover body 23 slides and completely covers the opening, the protrusion of the cover body 23 protrudes from the container 21, so that a person can pull the cover body 23 by hand when sliding the cover body 23 left or right; alternatively, at least one convex strip 234 is formed on the top of the cover body 23 to facilitate a person's hand to act on the cover body 23 to slide the cover body 23 left or right.

[0046] The cover 23 of this embodiment includes a cover portion 231 connected to the container 21 and a flip cover portion 232 rotatably connected to the cover portion 231. The flip cover portion 232 is rotated to open and close on the opening of the container 21. A handle 235 is provided on the end of the flip cover portion 232. Half of the cover 23 can be opened by directly holding the handle 235. The cover 23 of this embodiment can be first installed and limited to the opening of the container 21 by sliding as in Example 1, and the flip cover portion 232 is then connected to the container 21 by forming a friction force with the container 21, or by providing a buckle at the end of the flip cover portion 232 to close the opening of the container 21.

[0047] The cover portion 231 in this embodiment is the same size as the flip cover portion 232. Of course, in other embodiments, the cover portion 231 may be smaller and the flip cover portion 232 may be larger, or the cover portion 231 may only be used as the size of a rotating shaft, and the cover body 23 may be rotated on the opening of the container 21 to open and close.

[0048] Example 3

[0049] This embodiment discloses an air filter with air treatment function, referring to Fig. 9 , the only difference from Embodiment 2 is that the frame 102 is different.
