Description

Technical Field

[0001] This utility model relates to the technical field of automotive air conditioning parts, and in particular to a filter with fragrance. Background Technology

[0002] The car air conditioning filter is an important component of the car air conditioning system. Its main function is to filter out impurities such as dust, pollen, and odors from the air entering the car, providing a relatively clean air environment for the occupants and protecting their respiratory health. As people's living standards improve, their demands for the comfort of the car's interior environment are also increasing. Many users use car air fresheners to improve the odor environment inside their cars. However, most car air fresheners on the market require separate air freshener bottles or boxes, and also need to be equipped with independent fragrance control devices. This means that during use, the air fresheners not only take up extra space inside the car, but are also not very convenient to operate, requiring users to frequently adjust them manually or charge the battery regularly. In addition, during the car's operation, due to road bumps and other reasons, existing air fresheners may leak, and the leaked fragrance liquid will stain the car's interior, causing unnecessary trouble for users, thus limiting their options.

[0003] The reason for this problem is that existing fragrance diffusers and car air conditioning filters are independent of each other and cannot work together. Users need to operate and maintain the fragrance diffuser and the filter separately, which increases the user's steps and maintenance costs. In addition, most existing fragrance diffuser carriers use open or semi-open liquid storage structures. When the car is bumpy, the fragrance liquid inside is prone to leakage from the gaps or openings of the carrier due to shaking. Some fragrance diffuser boxes that use electric heating to diffuse fragrance require frequent charging or battery replacement, which has limitations. Utility Model Content

[0004] The purpose of this invention is to provide a fragrance-infused filter to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fragrance-infused filter, comprising a filter screen, wherein a fragrance unit is fixedly mounted on one side of the filter screen, and the fragrance unit comprises a fragrance box, a structural component, and a ball-type one-way valve. The structural component is integrally formed inside the fragrance box, and multiple sets of ball-type one-way valves are arranged on both sides inside the structural component, which ensure that the airflow can only be transmitted in one direction.

[0006] Preferably, the ball-type check valve includes a guide block and a check ball; The cross-section of the guide block is tapered from top to bottom; the one-way ball is movably engaged inside the guide block, and the one-way ball is tightly fitted to the inner wall of the guide block.

[0007] Preferably, the ball-type check valve further includes an anti-detachment plate: The anti-detachment plate is installed inside the structural component, and the anti-detachment plate has air holes inside.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This utility model provides, for example Figures 1 to 2The fragrance filter shown includes a filter 1, with a fragrance unit 2 fixedly mounted on one side of the filter 1. The fragrance unit 2 includes a fragrance box 21, a structural component 22, and a ball-type one-way valve 23. The structural component 22 is integrally formed inside the fragrance box 21. Multiple sets of ball-type one-way valves 23 are arranged on both sides inside the structural component 22. The ball-type one-way valves 23 ensure that the airflow can only be transmitted in one direction.

[0016] Example 1: In this example, when the car air conditioner is turned on, the airflow enters from the air inlet of the car air conditioner. It is first filtered by the filter screen 1. Then, part of the airflow blows from the air intake filter 25 of the fragrance box 21 towards the structural component 22. Under the action of the airflow, the one-way ball 232 in the ball valve 23 is blown. The one-way ball 232 moves upward and forms a gap between itself and the inner wall of the guide block 231. The airflow enters the structural component 22 through this gap and then flows through the fragrance layer 24, carrying the fragrance emitted by the fragrance layer 24. After being filtered by the air outlet filter 26, it merges with another part of the airflow filtered by the filter screen 1 and enters the car interior together, providing clean air with a comfortable fragrance. When the car air conditioner is turned off, the airflow stops, and the one-way ball 232 falls back under its own gravity and fits tightly against the inner wall of the guide block 231, preventing the fragrance layer 24 from continuously dissipating its fragrance and ensuring the service life of the fragrance layer 24, so that it can be consistent with the service life of the filter screen 1.

[0017] like Figure 3 The fragrance filter shown includes a filter 1, with a fragrance unit 2 fixedly mounted on one side of the filter 1. The fragrance unit 2 includes a fragrance box 21, a structural component 22, and a ball-type one-way valve 23. The structural component 22 is integrally formed inside the fragrance box 21. Multiple sets of ball-type one-way valves 23 are arranged on both sides inside the structural component 22. The ball-type one-way valves 23 ensure that the airflow can only be transmitted in one direction.

[0018] The ball-type one-way valve 23 includes a guide block 231 and a one-way ball 232. The cross-section of the guide block 231 is tapered from top to bottom. The one-way ball 232 is movably engaged inside the guide block 231, and the one-way ball 232 is tightly fitted to the inner wall of the guide block 231. The ball-type one-way valve 23 also includes an anti-detachment plate 233: the anti-detachment plate 233 is disposed inside the structural component 22, and the anti-detachment plate 233 has air holes inside, which is used to prevent the one-way ball 232 from detaching from the inside of the guide block 231. A fragrance layer 24, which is a microporous ceramic fragrance carrier, is fixedly assembled in the middle section of the structural component 22. An air inlet filter 25 is fixedly assembled at one end of the structural component 22. An air outlet filter 26 is fixedly assembled at the other end of the structural component 22.

[0019] Example 2: In this example, the filter 1 is made of activated carbon filter 1 material, and is cut and processed according to the size of the air conditioning filter 1 of different car models. The fragrance box 21 is made of plastic material injection molding, and its interior is integrally molded with the structural component 22. The structural component 22 and the fragrance box 21 are spliced ​​structures, which are spliced ​​and fixed by clips. The structural component 22 has mounting holes on both sides for installing the ball-type one-way valve 23. The guide block 231 is fixed in the mounting hole by clipping. Then, the one-way ball 232 is placed inside the guide block 231 to ensure that the one-way ball 232 is tightly attached to the inner wall of the guide block 231. Then, the anti-detachment plate 233 is fixed inside the structural component 22 by screws, located at the upper end of the one-way ball 232. The air holes on the anti-detachment plate 233 are used to ensure that the airflow can pass normally. The fragrance layer 24 is fixed in the middle of the structural component 22 by adhesive bonding. The fragrance layer 24 is a microporous ceramic fragrance carrier. It should be noted that the service life of the internal filter 1 of a car is usually limited and it needs to be replaced when it reaches the end of its service life. However, the fragrance layer 24 used in this application has the same service life as the filter 1, so that the fragrance layer 24 can be replaced at the same time as the filter 1, without causing waste. The intake filter 25 is installed at one end of the structural component 22 by snap-fit, and the exhaust filter 26 is installed at the other end by snap-fit. The intake filter 25 and the exhaust filter 26 can be non-woven fabric filters, thus completing the preparation of the device.

[0020] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
