The invention relates to the field of air compressors, in particular to a mute air compressor which comprises a case with an inner cavity, an air cylinder arranged on the case and a cylinder cover arranged on the air cylinder, a valve plate used for separating the air cylinder from the cylinder cover is arranged between the air cylinder and the cylinder cover, and a compression chamber is arranged between the interior of the air cylinder and the valve plate; an air inlet chamber and an air outlet chamber which are not directly communicated with each other are arranged between the cylinder cover and the valve plate, and the air inlet chamber and the air outlet chamber are separated by a partition plate arranged in the cylinder cover; the air inlet chamber and the compression chamber are selectively communicated in a one-way mode, and the compression chamber and the air outlet chamber are selectively communicated in a one-way mode. An air inlet for communicating the inner cavity with external air and a first air inlet channel communicated with the inner cavity are formed in the case; the air cylinder is provided with a second air inlet channel connected with the air outlet end of the first air inlet channel, the valve plate is provided with a first through hole communicated with the air outlet end of the second air inlet channel, and the first through hole is communicated with the air inlet chamber. The air inlet path is prolonged, and noise generated when the air compressor works is effectively reduced.
Description
technical field [0001] The invention relates to the field of air compressors, in particular to a silent air compressor. Background technique [0002] Air compressor is a kind of equipment for compressing gas, which is widely used in various fields of industrial production, mainly used to provide power source for pneumatic tools and so on. However, the air compressor will generate a lot of noise when it is working, especially the noise generated by the air flow, which will have a certain impact on people's production and life. In order to reduce the above-mentioned noise, a muffler is usually installed at the intake position of the air compressor (usually located on the cylinder head). The principle of the muffler is roughly divided into two types, one is to change the volume of the air path suddenly, and the other is to lengthen the path. . [0003] Existing silent air compressors, such as Chinese utility model patent (publication number: CN208885524U, publication date: 20...
