[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] See attached Figure 1-7 As shown, a dual-channel air pump for a breast pump includes a pump body 1, a first valve body 4, and a second valve body 5, and a silent chamber 2 connected to the pump body 1.

The silent chamber 2 is provided with an integrated pipe member 3, which is provided with an air inlet 31 connected to the air intake chamber 21, an air passage 32 connected to the first valve body 4, and an air passage 33 connected to the second valve body 5. The provision of the integrated pipe member 3 allows the various components to be directly connected through the structure, that is, the air passage within the structure connects the various components. This not only avoids the original error of the air pipe connection and the error of the air pipe itself, but also ensures consistent suction force on both breast cups. The internal air passage connection eliminates air passage transmission noise, greatly reducing air passage transmission noise. The provision of the silent chamber 2 can isolate most of the noise within the silencer chamber, allowing the silencer chamber to be larger in volume, with strong overall rigidity and sound insulation performance. The air passage 32 of the first valve body 4 and the air passage 33 of the second valve body 5 are symmetrically arranged, which further reduces possible air passage errors and makes the suction of the double-sided breast shield more consistent.

The integrated arrangement makes the structure easy to install and the overall structure is simple and stable. The integrated pipe member 3 extends in one direction with an extension arm 36, and the air inlet duct 31 is arranged in the extension arm 36. The air inlet duct 31 can be reasonably extended by the extension arm 36, and cooperates with the silent chamber 2 so that the gas can pass through the entire silent chamber 2, and the overall noise reduction effect is better.
