Technical Field
[0001] This utility model belongs to the technical field of automotive air filtration equipment, specifically relating to an oxygen-enriched air filtration component for automobiles. Background Technology
[0002] As people's living standards continue to improve, automobiles have become an important means of daily transportation. During vehicle operation, the air quality inside the car directly affects the health and comfort of the driver and passengers. As a key component ensuring in-vehicle air quality, the performance of the automotive air filter is of paramount importance.
[0003] Currently, most common automotive air filter components on the market only have basic air filtration functions, mainly using simple filters to intercept larger impurities such as dust and particles in the air. However, facing increasingly complex air environments, these traditional filter components have many limitations. On the one hand, their filtration accuracy is limited, making it difficult to effectively remove small particles, harmful gases, and moisture from the air, failing to meet people's demand for high-quality in-vehicle air. On the other hand, traditional components generally do not have oxygen-enriching functions. In the long-term closed space of the car, especially in special scenarios such as traffic congestion and high-altitude areas, the oxygen content inside the car will gradually decrease, causing discomfort symptoms such as dizziness and fatigue for drivers and passengers, affecting driving safety and comfort. Therefore, those skilled in the art have provided an automotive oxygen-enriching air filter component to solve the above-mentioned problems. Utility Model Content
[0004] The purpose of this invention is to provide a simple and reasonably designed oxygen-enriched air filter assembly for automobiles in order to solve the above-mentioned problems.
[0005] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a shell, and filter components are installed inside the shell. The filter components include a multi-stage filter plate, a pervaporation membrane, an oxygen molecular sieve, and a compressor installed inside the shell. The pervaporation membrane is located between the multi-stage filter plate and the compressor. The compressor and the multi-stage filter plate are located on one side of the pervaporation membrane. The pervaporation membrane is located inside a working hood installed inside the shell. The input end of the compressor is connected to the side wall of the working hood, and the output end of the compressor is connected to the input end of the oxygen molecular sieve.
[0006] As a further optimization of this utility model, one end of the oxygen molecular sieve is connected to an oxygen supply pipe that penetrates the front sidewall of the outer shell, and the other end of the oxygen molecular sieve is connected to a nitrogen discharge pipe located inside the outer shell.
[0007] As a further optimization of this utility model, a fan that cooperates with the nitrogen exhaust pipe is installed on the inner side wall of the outer shell.
[0008] As a further optimization of this utility model, an exhaust grille is installed on the rear side wall of the outer shell at the exhaust end of the fan.
[0009] As a further optimization of this utility model, a metal barrier mesh is installed on the inner wall of the outer shell and on one side of the filter assembly.
[0010] As a further optimization of this utility model, a box cover is installed on the top of the outer shell, located above the metal barrier mesh and the multi-stage filter plate.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. This utility model, through the setting of core components such as multi-stage filter plates, pervaporation membranes, oxygen molecular sieves, and compressors, forms a complete air treatment system. The multi-stage filter plates consist of primary, medium, and high-efficiency filter layers, which can perform fine filtration of the air layer by layer, removing large dust particles, pollen, and tiny suspended particles and other impurities. The pervaporation membrane further removes moisture from the air. The oxygen molecular sieve, using the pressure swing adsorption principle, separates oxygen and nitrogen in the air with the cooperation of the compressor, and delivers oxygen-enriched air to the car interior through an oxygen supply pipe, realizing the organic combination of air purification and oxygenation functions, providing a healthier and more comfortable air environment for the occupants of the vehicle.
[0013] 2. In this utility model, the cover installed on the top of the outer shell is fixed with bolts, which is easy to disassemble, making the inspection and replacement of internal components such as filter components simple and easy; the metal barrier mesh installed on the inner wall of the outer shell can effectively protect the filter components, reduce the risk of equipment damage caused by external impacts and other factors, extend the service life of the components, and reduce maintenance costs.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0019] Example 1
[0020] like Figure 1 As shown, this utility model includes a housing 1, which is rectangular in shape for easy installation in a specific location inside a car. Inside the housing 1 is a core filter assembly 2, which includes a multi-stage filter plate 201, a pervaporation membrane 202, an oxygen molecular sieve 203, and a compressor 204. The multi-stage filter plate 201 is tightly installed inside the housing 1 near the air inlet and consists of a primary filter layer, a medium-efficiency filter layer, and a high-efficiency filter layer, capable of sequentially filtering out large dust particles, pollen, and tiny suspended particles from the air. The pervaporation membrane 202 is located between the multi-stage filter plate 201 and the compressor 204, specifically installed inside a specially designed working hood within the housing 1. This working hood is a sealed structure to ensure effective air treatment. The pervaporation membrane is a polymer or ceramic thin film with selective permeation function, its surface densely covered with nanoscale micropores, exhibiting preferential adsorption and diffusion capabilities for water molecules. After the air passes through the multi-stage filter plate 201 to filter particulate impurities, it enters the working hood where the pervaporation membrane 202 is located. Water vapor in the air is adsorbed by the membrane material and, driven by the vapor pressure difference on both sides of the membrane, it permeates through the membrane layer to form liquid water which is discharged (or condensed and collected). The dry air then continues to enter the compressor 204. The input end of the compressor 204 is connected to the side wall of the working hood through a pipe, and the output end of the compressor 204 is connected to the input end of the oxygen molecular sieve 203 through another pipe. The compressor 204 can pressurize the air after it has been treated by the pervaporation membrane 202, so that it can smoothly enter the oxygen molecular sieve 203.
[0021] like Figures 1-3 As shown, one end of the oxygen molecular sieve 203 is connected to an oxygen supply pipe 206, which penetrates the front side wall of the outer shell 1 to deliver the separated oxygen-enriched air to the interior of the vehicle. The other end of the oxygen molecular sieve 203 is connected to a nitrogen exhaust pipe 205, which is located inside the outer shell 1 and is used to exhaust the separated nitrogen. On the inner side wall of the outer shell 1, a fan 4 that cooperates with the nitrogen exhaust pipe 205 is installed. The fan 4 is fixed to the inner wall of the outer shell 1 by a bracket, and its air inlet is connected to the nitrogen exhaust pipe 205 to accelerate the exhaust of nitrogen. An exhaust grille 6 is installed on the rear side wall of the outer shell 1. The exhaust grille 6 is located at the exhaust end of the fan 4 and is used to exhaust the nitrogen discharged by the fan 4 to the outside of the vehicle.
[0022] like Figure 2 , Figure 3 As shown, a metal barrier mesh 3 is bolted to the inner wall of the outer casing 1 and located on one side of the filter assembly 2. The metal barrier mesh 3 can prevent the filter assembly 2 from being accidentally impacted and play a protective role. A box cover 7 is installed on the top of the outer casing 1, which is located above the metal barrier mesh 3 and the multi-stage filter plate 201. The box cover 7 is fixedly connected to the outer casing 1 by bolts, which facilitates the inspection and replacement of internal components such as the filter assembly 2.
[0023] It should be noted that when this utility model is in use: outside air first enters through the air inlet on the outer shell 1, and after being filtered layer by layer by the multi-stage filter plate 201 to remove impurities, it enters the pervaporation membrane 202 inside the working hood to further remove moisture and other substances from the air. Then, under the action of the compressor 204, the air enters the oxygen molecular sieve 203, where the oxygen molecular sieve 203 separates oxygen and nitrogen. The oxygen-enriched air is delivered to the interior of the car through the oxygen supply pipe 206, while the nitrogen is discharged to the outside of the car through the nitrogen exhaust pipe 205 and under the action of the fan 4 through the exhaust grille 6, thereby realizing the function of providing oxygenated and clean air inside the car.
[0024] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
