The low-noise air pumping device comprises an air pump body, an air pump end cover, a pressure regulating valve, a control panel, a control electromagnetic valve, a silencing block and a controller cover, the air pump end cover is fixed to the air pump body in a fastening connection mode through a buckle or a screw, the pressure regulating valve is installed in a pressure regulating valve installation hole of the air pump end cover, and the control panel is connected with the control electromagnetic valve. The control electromagnetic valve and the control panel are fixed into a whole through screws, and the controller cover is fixed to the air pump end cover in a buckle or screw fastening mode. The low-noise air pumping device for the pneumatic waist support is simple in structure, and the pressure-regulating and air-releasing flow channel is arranged in the air pump end cover, so that pressure-regulating and air-releasing air flow noise is shielded in the air pumping device by the air pump body and the air pump end cover, and the pressure-regulating and air-releasing noise is eliminated; and the electromagnetic valve exhaust groove is covered in the controller cover, and the exhaust noise reduction block for suppressing the exhaust noise of the electromagnetic valve is arranged in the electromagnetic valve exhaust groove, so that the exhaust noise of the electromagnetic valve is suppressed, and the low-noise performance of the air pumping device is realized.
本发明提供了一种用于气动腰托的低噪音泵气装置,包括:气泵体、气泵端盖、调压阀、控制板、控制电磁阀、消音块和控制器罩,气泵端盖通过卡扣或螺钉紧固的连接方式固定在气泵体上,调压阀安装在气泵端盖的调压阀安装孔内,螺钉将控制电磁阀与控制板固定成一个整体,控制器罩通过卡扣或螺钉紧固的方式固定在气泵端盖上。本用于气动腰托的低噪音泵气装置结构简单,通过在气泵端盖内部设置调压泄气流道使调压泄气的气流噪音被气泵体和气泵端盖屏蔽在泵气装置内部而消除了调压泄气噪音的同时,电磁阀排气槽被罩在控制器罩内部并且在电磁阀排气槽内设置有抑制电磁阀排气噪音的排气消音块而抑制了电磁阀排气噪音,实现本泵气装置的低噪音性能。
