Description

Technical Field

[0001] The utility model belongs to the technical field of filters and relates to an impact-resistant and high-life filter. Background Art

[0002] An air conditioner filter is a device for filtering dust particles and microorganisms in the air and is mainly applied to air conditioning systems and ventilation systems. Among them, an air conditioner drying filter is a fitting for a refrigeration system and is mainly used to clean harmful substances in the system to protect important components such as expansion valves and compressors. Its main function is to adsorb moisture from the refrigeration system, which is a very important function. The inside of the drying filter is mainly composed of molecular sieves with excellent hygroscopicity as desiccants. These desiccants can effectively absorb moisture in the refrigerant, ensure the unobstructed flow of the capillary tube, and enable the refrigeration system to operate normally. If the desiccant fails due to excessive moisture absorption, it needs to be replaced in a timely manner. In addition, there is another structure of the drying filter that does not contain desiccants and only contains a metal mesh, which is used to collect solid impurities in the system and lubricating oil to prevent the system, capillary tube, and expansion valve from being blocked, thereby ensuring the unobstructed flow of the pipeline system. However, the current structure of the air conditioner drying filter is relatively single, usually composed of only a simple filter screen and desiccant. After long-term use, the filtering effect will be poor; at the same time, most of the existing filters are integrally manufactured, and cutting and separation are required during replacement and maintenance, resulting in a high maintenance cost. Summary of the Utility Model

[0010] In the above-mentioned impact-resistant high-life filter, two annular grooves are correspondingly formed on the outer wall of the main body, and anti-slip patterns are provided on the outer wall of the main body between the two annular grooves.

[0011] In the above-mentioned impact-resistant high-life filter, the outer wall diameters of the main body, the first section and the second section are the same, and the outer wall diameters of the input pipe and the output pipe are both smaller than the outer wall diameter of the main body.

[0012] In the above-mentioned impact-resistant high-life filter, the inner wall diameter of the input pipe is larger than the inner wall diameter of the output pipe, and the input pipe and the output pipe are both connected in a through manner inside the first section and the second section.

[0013] In the above-mentioned impact-resistant high-life filter, positioning grooves are formed on both sides of the outer side of the input pipe. The positioning grooves are semi-circular groove structures and are arranged correspondingly.

[0014] In the above-mentioned impact-resistant high-life filter, the adsorption beads are round beads made of adsorption material. The adsorption beads are evenly placed inside the spring respectively, and the diameters of several adsorption beads are connected in contact.

[0015] Compared with the existing technology, the advantages of the present utility model are as follows:

[0016] In the present utility model, a secondary filter plate is fixedly installed inside the main body, and at the same time, a first section and a second section are respectively screwed and connected to both ends of the main body through threads, so that the main body, the first section and the second section can form a complete sealed whole.
