Description

Technical Field

[0001] This utility model relates to the field of air conditioner filter water barrier design technology, specifically, to an air conditioner filter with an added water barrier layer on the outer layer of the air conditioner filter. Background Technology

[0002] Most air conditioning filters used in the industry consist of an air conditioning filter layer and an outer sealing layer connected by an EVA adhesive coating to form a sealed outer channel. Outside air enters the vehicle through the air conditioning filter. When the outside air humidity increases in humid weather or when the air is being cooled, the circulating air cools the air conditioning filter paper, causing it to absorb moisture and become damp, thus affecting filtration efficiency and increasing air intake resistance. Damp filter material can also breed bacteria. In some cases, condensation droplets can even enter the lowest ventilation opening of the vehicle directly through the ventilation duct. To solve this problem and reduce mold contamination caused by damp filter, this solution adds a PBT woven mesh water-proof layer to the outside of the existing product to isolate and collect moisture in the incoming air. After collection, small raindrops are collected through the top nylon sponge water storage layer on the outside, adding a barrier layer to the moisture on the air conditioning filter material from the outside, allowing only dry air to enter the vehicle interior.

[0026] Example

[0027] like Figure 1 and Figure 2 This utility model proposes an air conditioner filter with an added water-proof layer on the outer layer of the air conditioner filter screen. The air conditioner filter includes: an outer edge sealing layer 1, an EVA coating layer 2, an air conditioner filter element 3, a PBT woven mesh water-proof layer 4, and a top nylon sponge water-absorbing layer 5.

[0028] The EVA coating layer 2 covers the inner perimeter of the outer sealing layer 1; the outer sealing layer 1 and the air conditioning filter material 3 are bonded together by the EVA coating layer 2; the water-absorbing layer 5 is connected to the outer sealing layer 1 to form a sealed outer shell; the water-absorbing layer 5 is located outside the water-proof layer 4, and the water-proof layer 4 is in contact with the air conditioning filter material 3.

[0029] When the vehicle's air conditioning system is turned on, air from the outside environment passes through the air conditioning filter before entering the vehicle's interior. The working principle is as follows: Figure 3 As shown, large particles, fibers, and even leaves from the outside air enter the air conditioning system through the ducts. When the outside air comes into contact with the air conditioning filter, the PBT woven mesh waterproof layer 4 first comes into contact with the air, blocking and trapping particles and moisture larger than 300 micrometers. Particles smaller than 300 micrometers pass through the air conditioning filter element material 3, trapping particulate matter from the air outside the set range on the filter element surface, allowing clean air that meets design specifications to enter the vehicle interior and meet different usage needs.

[0030] Air conditioning filters, as important components of passenger and commercial vehicles, are suitable for both gasoline and electric vehicles. This solution is based on the general air conditioning filter structure, adding a top nylon sponge water-absorbing layer 5 and a PBT woven mesh water-proof layer 4 to its air intake surface. This allows water molecules in humid air to be trapped on the surface of the PBT woven mesh water-proof layer 4. When a certain amount accumulates, it forms small water droplets, which slide off around the air conditioning filter as the vehicle moves. Utilizing the water-absorbing properties of the top nylon sponge water-absorbing layer 5, the small water droplets are trapped, preventing them from spreading and entering the vehicle's interior. The outer sealing layer 1 of the automotive air conditioning filter is used to provide air conditioning... The filter element material 3 is supported and positioned by the folded paper. The outer edge sealing layer 1 is fully coated with EVA adhesive layer 2, which makes the air conditioning filter element material 3 and the outer edge sealing layer 1 firmly bonded and form a sealed whole. The top nylon sponge water-absorbing layer 5 and the outer edge sealing layer 1 together form a sealed shell. The external air can only enter the vehicle interior after being filtered by the PBT woven mesh water-proof layer 4 and the air conditioning filter element material 3. When the external air humidity decreases, the moisture in the top nylon sponge water-absorbing layer 5 will gradually dry with the air intake during driving, thus ensuring that the air in the entire circulation system is dry and clean.

[0031] The waterproof layer 4 is made of a waterproof material with a microporous structure, which can effectively block liquid water from passing through while maintaining air circulation.

[0032] The absorbent layer 5 is made of highly absorbent resin fibers, which can quickly absorb and lock in excess moisture carried in the air, preventing moisture from penetrating into the air conditioning system.

[0033] The EVA coating layer 2 contains an antibacterial agent, which can effectively inhibit the growth of bacteria and mold on the filter and ensure air quality.

[0034] The air conditioning filter material 3 adopts a multi-layer structure, including but not limited to a pre-filter layer, a HEPA high-efficiency filter layer, and an activated carbon adsorption layer, so as to effectively filter particulate matter and harmful gases of different sizes.

[0035] The outer sealing layer 1 is made of elastic material, which can adapt to the installation interface of different models of air conditioners, ensuring sealing while facilitating installation and replacement.

[0036] A reinforcing mesh layer is provided between the water-proof layer 4 and the air conditioning filter material 3 to enhance the structural stability between the two layers and extend their service life.

[0037] The surface of the water-absorbing layer 5 is provided with water-guiding channels, which can guide the absorbed water to be discharged to the outside of the air conditioner along a specific path, thus avoiding water accumulation.

[0038] The EVA coating layer 2 is fixed by ultraviolet curing technology, which ensures bonding strength while reducing the release of volatile organic compounds, making it more environmentally friendly.

[0039] The air conditioner filter is designed with a detachable structure, which makes it convenient for users to clean or replace the components regularly, and maintenance is simple.

[0040] A color indicator strip is provided between the waterproof layer 4 and the absorbent layer 5. When the absorbent layer reaches saturation, the color changes to remind the user to replace it in time, thus improving the convenience of use.
