Detailed Description
As shown in fig. 1, a cylinder assembly of an air compressor, which is a part of a head of the air compressor, is installed on a housing of the air compressor, and a piston reciprocates in the cylinder assembly during operation, thereby compressing air. The cylinder assembly comprises a cylinder 6 positioned at the lower part and a cylinder cover 8 positioned at the upper part, and a valve plate 7 is arranged between the cylinder 6 and the cylinder cover 8.
As shown in fig. 2, the lower portion of the cylinder 6 is provided with an extension plate 63 extending downward, the cylinder 6 is positioned on the casing of the air compressor through the extension plate 63, the right side of the cylinder 6 is provided with an air inlet channel 61 penetrating up and down, the valve plate 7 is provided with a first through hole 73 communicating with the air outlet end of the air inlet channel 61, and the air outlet end of the first through hole 73 is communicated with the inside of the cylinder cover 8.
As shown in fig. 3, a chamber is arranged inside the cylinder head 8, and is divided into an inlet chamber 801 and an outlet chamber 802 which are not directly communicated through a partition plate 81, a baffle 83 is arranged in the inlet chamber, a silencing cavity 82 is formed between the baffle 83 and the inner wall of the cylinder head 8, and the silencing cavity 82 is used for installing silencing sponge. The silencing cavity 82 is communicated with the air inlet chamber through the opening 84, the silencing cavity 82 is located at the air outlet end of the first through hole 73, so that when the air compressor enters air, the air sequentially enters the silencing cavity 82 through the air inlet channel 61 and the first through hole 73, under the action of the silencing sponge, the entering air is silenced, and then the air flows into the air inlet chamber.
The specific structure of the valve plate 7 is as shown in fig. 2, a valve plate air inlet 71 and a valve plate air outlet 72 penetrating the upper and lower surfaces are provided on the valve plate 7, an air inlet valve plate 711 is provided below the valve plate air inlet 71, and an air outlet valve plate 721 is provided above the valve plate air outlet 72. A compression chamber is formed between the valve plate 7 and the cylinder 6. The partition plate 81 partitions the valve plate air inlet 71 and the valve plate air outlet 72, so that an air inlet chamber 801 and an air outlet chamber 802 which are not communicated are formed inside the cylinder head 8.
With the above structure, when the volume of the compression chamber is increased and the pressure difference between the intake chamber 801 and the compression chamber can open the intake valve plate 711, air pushes the intake valve plate 711 downward from the intake chamber into the compression chamber under the action of negative pressure. When a certain amount of air is reserved in the compression chamber, the piston in the cylinder 6 moves upwards, the volume of the compression chamber starts to be gradually reduced, the air in the compression chamber starts to be compressed, so that the pressure of the compression chamber is increased, and when the pressure difference between the compression chamber and the air outlet chamber can push the air outlet valve plate 721 up, the compressed air in the compression chamber passes through the air outlet valve plate 721 and enters the air outlet chamber.
As shown in fig. 2, the valve plate 7 is provided with a second through hole 74 communicated with the air outlet chamber, and the cylinder 6 is provided with an air outlet channel 62 communicated with the air outlet end of the second through hole 74, so that the path of air exhaust is prolonged, and the noise is reduced.
On the basis of the structure, the following improvements can be further made:
as shown in fig. 3, the muffling cavity 82 is located at one end of the cylinder cover 8, and is cylindrical, and the volume of the muffling cavity 82 is approximately equal to that of the intake chamber 801, and the cross section of the muffling cavity 82 is far larger than the diameter of the first through hole 73, which is beneficial to improving the muffling effect.
As shown in fig. 3, the edge portion 85 is provided on the edge of the cylinder head 8, the mounting hole 851 is provided on the edge portion 85, and a screw is provided in the mounting hole 851, so that the cylinder head 8, the valve plate 7, and the cylinder 6 are connected by a screw when mounted, thereby facilitating the mounting and dismounting.
As shown in fig. 3, a plurality of parallel radiating fins are arranged on the outer surfaces of the cylinder 6 and the cylinder cover 8, so that the radiating effect is improved.
