Description
技术领域technical field
本发明涉及气泵电路技术领域，尤其涉及一种双电压气泵驱动电路及其泵体。The invention relates to the technical field of air pump circuits, in particular to a dual-voltage air pump drive circuit and a pump body thereof.
技术背景technical background
褥疮通常发生在因病或伤残或因伤残而长期卧床者。长期卧床者因体弱无力或残缺或意识丧失无法自主调节体位，长时间处于同一种卧位。在这种情况下，若护理工作稍有疏忽，便极不可能形成褥疮，防褥疮气床垫是专为减轻长期卧床病人的烦恼和痛苦，为减轻护理人员的劳动强度而设计制造的。它适用于长期卧床病人，是目前预防褥疮最有效的医疗器械之一。现在市场上用于防褥疮气床垫充气泵产品多为单一的电压类型：110V或220V，但有部分国家民用电同时使用110V和220V两种电压，如巴西，上述产品电器在使用时要碰到不同电压时，要用变压器来变压，比较麻烦。Bed sores usually occur in people who are bedridden for a long time because of illness or disability or because of disability. The long-term bedridden person is unable to adjust the body position independently due to weakness or disability or loss of consciousness, and stays in the same lying position for a long time. In this case, if the nursing work is a little negligent, it is extremely unlikely to form bedsores. The anti-bedsore air mattress is specially designed and manufactured to relieve the troubles and pains of long-term bedridden patients and to reduce the labor intensity of nurses. It is suitable for long-term bedridden patients and is currently one of the most effective medical devices for preventing bedsores. At present, most of the anti-decubitus air mattress air pump products on the market are of a single voltage type: 110V or 220V, but some countries use both 110V and 220V for civil electricity, such as Brazil, and the electrical appliances of the above products must be touched when using To different voltages, it is troublesome to use a transformer to change the voltage.
