[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Example 1

[0029] This embodiment discloses a ring-shaped air filter with air treatment function, referring to Figure 1-2, which comprises an annular filter paper 1, which is specifically an annular folded filter paper, and the two ends of the annular filter paper 1 are respectively connected with an upper cover 2 and a base 3, and the upper cover 2, the base 3 and the inside of the annular filter paper 1 form an inner cavity, and the upper cover 2 is provided with an air outlet 21 connected with the inner cavity, and air enters the inner cavity from the outside of the annular filter paper 1 and is then discharged from the air outlet 21, and the base 3 is connected with an air treatment component 4 for refreshing air, and the air treatment component 4 can be an aromatherapy component, and the air treatment component 4 is located in the inner cavity. By providing the base 3 and installing the air treatment component 4 on the base 3, when the air filter is ventilated and filtered of particulate matter, the air passing through the inner cavity will contact the air treatment component 4, so that the fragrance is emitted and discharged from the air outlet 21 with the filtered air, which has the effect of refreshing the air, and the inner cavity space of the annular air filter is fully utilized, avoiding the problem in the prior art that the annular filter paper 1 is shortened in height due to the installation of the aromatherapy component on the top, which affects the filtering efficiency, thereby ensuring good air filtering efficiency and refreshing air effect, and making the air filter structure more compact and optimized.

[0030] In this embodiment, refer to Figure 3-4 The air treatment component 4 includes an outer cover 41 and a fresh air functional part 42 arranged in the outer cover 41. The outer cover 41 has ventilation holes 411 on its surface. The outer cover 41 has an air guide surface 412 on its surface. The air guide surface 412 is inclined toward the air outlet 21. Specifically, the outer cover 41 is conical or trumpet-shaped. The conical outer cover 41 with the inclined air guide surface 412 has a guiding effect on the air. In this way, after the air enters the inner cavity from the outside of the annular filter paper 1, the outer cover 41 can guide the air toward the air outlet 21, which is beneficial to the circulation of the air after filtration, thereby better ensuring the smoothness of air filtration. Among them, the ventilation holes 411 are long strips extending along the height direction of the outer cover 41. A plurality of ventilation holes 411 are radially opened on the outer cover 41, which is beneficial to better ventilation and fragrance.

[0031] In this embodiment, the ratio of the height of the air treatment component 4 to the height of the annular filter paper 1 is 1 / 10 to 1 / 3. If the height of the air treatment component 4 is too high, it will affect the airflow. If the height of the air treatment component 4 is too low, most of the airflow will flow away directly and it will be difficult to take away the fragrance on the surface of the air treatment component 4. Therefore, setting the height ratio between the air treatment component 4 and the annular filter paper 1 within a specific range can better balance the air filtration efficiency and the fresh air effect of the air filter.

[0032] In this embodiment, the air treatment component 4 is detachably mounted on the base by snapping. Specifically, a card block 31 is provided on the base 3, and a card slot 413 that is snap-fitted with the card block 31 is provided at the bottom of the outer cover 41 of the air treatment component 4. When installing, the card block 31 can be snapped into the card slot 413 or removed from the card slot 413 by rotating the air treatment component 4, so as to achieve detachable installation, so as to replace the fresh air functional part. Of course, in other embodiments, the air treatment component 4 can also be detachably mounted on the base 3 by Velcro. Since the air treatment component 4 is detachably mounted in the filter element, it is not only convenient and quick to install and disassemble, but also stable after installation and not easy to fall out. Users can freely choose whether to install the air treatment component 4 according to their needs, or install air treatment components 4 with different functions, which is more personalized.

[0033] In the present embodiment, the fresh air functional component 42 is in the shape of a rod. Taking the aromatherapy stick as an example, the fresh air functional component 42 is an aromatherapy stick formed by integrating functional materials (spices, flavors, etc.) with injection molding plastic. In addition to being an aromatherapy stick, it can also be a deodorizing stick, a sterilizing stick, a vitamin C stick, etc. The aromatherapy stick masks the odor in the air by emitting fragrance, the deodorizing stick eliminates odor by reacting with odorous substances in the air, the sterilizing stick eliminates odor caused by complex bacteria by inhibiting or killing bacteria in the air, and the vitamin C stick makes the air fresher by emitting moist components into the air. Users can choose different fresh air functional components 42 for installation according to their needs, so that the air filtered by the air filter has the functions of removing odor, sterilizing, emitting fragrance or releasing vitamin C to meet the different needs of users.

[0034] In this embodiment, an end cover 43 is provided on the top of the outer cover 41, and a clamping member 431 for clamping the fresh air functional component 42 is provided under the end cover 43. The base 3 is provided with a positioning column 32 coaxial with the clamping member 431. The upper end of the fresh air functional component 42 is inserted into the clamping member 431, and the lower end thereof is inserted into the positioning column 32, so that the fresh air functional component 42 is stably installed between the clamping member 431 and the positioning column 32.

[0035] In this embodiment, the annular air filter is cylindrical in shape as a whole. In other embodiments, it can also be designed to be elliptical in shape as a whole according to needs.

[0036] Example 2

[0037] This embodiment discloses an annular air filter with air treatment function, which is different from the embodiment 1 in that Figure 5-6The one-piece aromatherapy stick fresh air functional part 42 is replaced by a container 421 and a functional material 422 (such as fragrance beads) built into the container 421. The top of the container 421 is connected to the end cover 43. The side wall of the container 421 is provided with a through hole as an air inlet 423. The top of the end cover 43 is provided with an air outlet 432. The air outlet 432 can be formed as a hollow LOGO or a pattern. The air inlet 423 and the air outlet 432 on the fresh air functional part 42 can not only further improve the odor emission effect, but also help to further improve the air circulation smoothness of the inner cavity of the annular filter paper 1, thereby improving the air filtration efficiency.
