Description

An air-cooled air compressor integrated with a gas tank Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air-cooled air compressor integrated with a gas tank. Background Art

[0002] An air compressor, or simply an air compressor, is the main component of an air source device. It converts the mechanical energy of a prime mover (usually an electric motor) into gas pressure energy and is a device that generates compressed air. Some air compressors are equipped with a gas tank to store compressed air for easy user access. For example, a Chinese patent application (publication number: CN202900568U) discloses a gas tank-type air compressor comprising a housing, a gas tank, and a core assembly. The housing houses the core assembly and is fixedly connected to the gas tank. The core assembly includes a drive assembly, a transmission assembly, and a pump head assembly. The drive assembly is connected to the pump head assembly through the transmission assembly, and the pump head assembly is connected to the gas tank via an air pipe. The drive assembly, transmission assembly, and pump head assembly are arranged horizontally on the top of the gas tank. The core assembly is surrounded by an inner core housing. Its compact structure and rational layout facilitate ventilation and heat dissipation of core components, as well as easy disassembly and installation. Its small size and light weight make it easy to carry and use. It also reduces noise during operation and facilitates installation of ventilation equipment, extending the service life of the entire machine.

[0003] When the air compressor is working, it will generate water vapor and bring the water vapor into the gas tank. Conventional gas tanks are usually made of iron. After long-term use, the inside of the gas tank is prone to rust, affecting normal use. Therefore, the inner wall of the gas tank is usually sprayed with anti-rust paint. However, the gas tank of the above-mentioned gas tank air compressor is integrally formed, and the hole opened on the gas tank is small, which makes it difficult to evenly spray the anti-rust paint to the inner wall of the gas tank. Therefore, it is necessary to improve it. Utility Model Content
