Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, and more specifically, to an air filter structure of an air compressor. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. They can be divided into several types according to their working principles, lubrication methods, and performance. Air compressors are large equipment. When the air is taken in, the air filter structure is required to purify the air entering the air because the air contains small particles of impurities and dust.

[0003] However, there are various types of air filtering structures in the prior art. For example, invention patent CN216537420U relates to an air filtering device for an air compressor. The utility model is provided with an upper shell, an air inlet is provided on the left side of the upper shell, and a lower shell is attached to the lower side of the upper shell; an air outlet is provided on the right side of the lower shell, and bolts are provided at both ends of the upper shell and the lower shell; a filter is provided inside the lower shell, and a quick-change mechanism is provided at both ends of the filter; the quick-change mechanism includes a fixed plate, a positioning unit, a push plate and an auxiliary movable unit, and both ends of the filter are inserted in the fixed plate; the side of the fixed plate away from the filter is fixedly connected to the lower shell, and the positioning unit is inserted inside the two ends of the filter; the upper side of the positioning unit is fixedly connected to the push plate, and an auxiliary movable unit is provided at the middle end of the push plate, so that the internal filter can be quickly disassembled and replaced after the air filtering device has been used for a period of time, thereby improving the filtering effect of the air filtering device.

[0004] Although the air filter device can quickly disassemble and assemble the filter to facilitate cleaning or replacement of the filter, since water vapor will also be introduced into the air compressor along with the air, the moisture in the air is likely to reduce the life of the equipment and increase the failure rate of the equipment. The device is difficult to intercept and remove water vapor in the air, and it is easy to generate loud noise when the air enters and exits, which affects the practicality of the device and cannot meet current usage needs. In order to avoid this phenomenon, it is very necessary to design an air filter structure for an air compressor. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0006] In order to achieve the above object, the utility model provides an air filter structure of an air compressor, which is achieved by the following specific technical means:

The end of the heat conducting pipe away from the filter assembly is connected to the air pipe, and one end of the air pipe extends into the fixed outer shell, and the heat conducting pipe and the fixed outer shell are interconnected through the air pipe.

[0009] Preferably, the heat conducting pipe is serpentine in shape, and the air flowing in the serpentine heat conducting pipe can prolong the residence time of the air, so that the air can be effectively dried in the serpentine heat conducting pipe.

[0010] Preferably, an air outlet pipe is embedded in a surface of a side of the fixed shell away from the air supply pipe, a first sound insulation felt is coaxially arranged on the outer surface of the air outlet pipe, and a second sound insulation felt is coaxially arranged on the outer surface of the filter cartridge.

[0014] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0015] When air is introduced into the air compressor from the air intake pipe, the air first passes through the purification of the filter cartridge to remove impurities and then enters the drying box. Then, the electric heating plate is energized and the two electric heating plates are used to heat the set heat pipe. As the air flows in the serpentine heat pipe, the residence time of the air can be extended, and the heat pipe is used to perform preliminary drying treatment on the air transported in the pipe. The multiple sound-absorbing sponges arranged in an alternating manner can form a curved air transmission channel. When the air flows in the air transmission channel, the residual moisture of the introduced gas can be absorbed, the water vapor contained in the air can be removed, and the moisture in the air can be prevented from entering the air compressor. At the same time, the sound-absorbing sponge can absorb the noise generated by the gas flow. With the arrangement of the first sound insulation felt and the second sound insulation felt, the noise can be further isolated, and the noise generated by the air compressor during air intake can be silenced, thereby increasing the service life of the equipment and tools and meeting the current usage needs.
